DETAILED DESCRIPTION OF THE INVENTION

In order to understand the technical solution of the utility model relatively intuitively and completely, a non-restrictive feature description will be provided in conjunction with the accompanying drawings of the utility model as follows:

Embodiment 1: A strength training station as shown in FIGS. 1 to 8 comprises a shell 1, two resistance mechanisms 2, a tension band 3, and a support frame.

The shell 1 comprises a top plate 11, an annular side wall, and a bottom plate 12. The annular side wall is connected between the top plate 11 and the bottom plate 12, and the annular side wall comprises an upper annular side plate 111 extending downwards from the circumference of the top plate 11 and a lower annular side plate 121 extending upwards from the bottom plate 12. The top plate 11 and the upper annular side plate 111 are integrally injection molded to form an upper shell 1a, and the bottom plate 12 and the lower annular side plate 121 are integrally injection molded to form a lower shell 1b, that is, the upper shell 1a and the lower shell 1b are made of plastic or other polymers that facilitate injection molding. The upper shell 1a and the lower shell 1b are oppositely buckled and locked by bolts, that is, the upper annular side plate 111 and the lower annular side plate 121 are oppositely buckled. Specifically, the upper annular side plate 111 comprises an upper inner side plate 1111 and an upper outer side plate 1112, the lower annular side plate 121 comprises a lower inner side plate 1211 and a lower outer side plate 1212, the upper inner side plate 1111 and the lower inner side plate 1211 are arranged in a staggered fit manner, and a lower edge of the upper outer side plate 1112 abuts against an upper edge of the lower outer side plate 1212, which can ensure the stability of buckled connection between the upper annular side plate 111 and the lower annular side plate 121. In order to increase the support strength of the lower annular side plate 121, a plurality of first rib plates 1213 are arranged between the lower inner side plate 1211 and the lower outer side plate 1212.

The support frame comprises an upper metal support plate 13 and six first support columns 122. The six first support columns 122 are supported between the upper metal support plate 13 and the top of the bottom plate 12. The top of the top plate 11 is formed with a recess 112 that accommodates the upper metal support plate 13. The upper metal support plate 13 is embedded in the recess 112 and locked with the top plate 11 by bolts. The recess 112 facilitates the positioning and mounting of the upper metal support plate 13. The upper metal support plate 13 is adapted to a top surface of the top plate 11 in shape and slightly smaller than the top surface of the top plate 11, which can improve the support strength of the product. An anti-slip pad 14 is arranged on a top surface of the upper metal support plate 13, and the anti-slip pad 14 is made of rubber or silicone. The anti-slip pad 14 can prevent a user from slipping when using the product, so as to increase the safety of the product. Specifically, the top plate, the bottom plate, and the upper metal support plate 13 are of rectangular structures.

The two resistance mechanisms 2 are distributed left and right at the bottom of the upper metal support plate 13, and the top plate 11 is provided with avoidance holes for avoiding the resistance mechanisms 2 and the first support columns 122. One end of the tension band 3 is connected to the resistance mechanism 2, and the other end extends out of the shell 1. Three of the first support columns 122 are distributed on the periphery of one resistance mechanism, and the other three first support columns 122 are distributed on the periphery of the other resistance mechanism, which can increase the mounting stability of the resistance mechanisms 2.

The bottom plate 12 is arranged opposite to the upper metal support plate 13, and a plurality of first support columns 122 are arranged between the upper metal support plate 13 and the bottom plate 12. The first support columns 122 are fixed on the bottom plate 12, the first support columns 122 are of metal tubular structures, and upper ends of the first support columns 122 are welded to the bottom of the upper metal support plate. The plurality of first support columns 122 are distributed below an area of the upper metal support plate 13 for feet to step on, which ensures the support strength of the stepping area. The bottom plate 12 is provided with positioning grooves 127 for positioning lower ends of the first support columns 122.

A space is formed between the bottom plate 12 and the upper metal support plate 13 by spacing arrangement to mount the resistance mechanisms 2 and the first support columns 122. The top plate 11 is provided with first avoidance holes 113 through which the first support columns 122 and the resistance mechanisms 2 pass. Through the first avoidance holes 113, the first support columns 122 pass through the top plate 11 and directly press against the upper metal support plate 13. The first support columns 122 further increase the support strength of the upper metal support plate 13. In order to prevent excessive pressure of the lower ends of the tubular first support columns 122 on the bottom plate 12, a metal gasket 128 that can be padded at the lower end of each first support column 122 is arranged in the positioning groove 127.

A plurality of second support columns are further arranged between the top plate 11 and the bottom plate 12, and the plurality of second support columns are distributed at intervals along the peripheries of the top plate 11 and the bottom plate 12 and located below the upper metal support plate 13. Because the first support columns 122 are arranged on the stepping area for supporting, the second support columns arranged along the peripheries can improve the support strength of the shell 1 to a greater extent. When the user steps on the upper metal support plate 13, the top plate 11 bears user's downward gravity. The second support columns can share the gravity borne by the top plate 11 to improve the support strength between the top plate 11 and the bottom plate 12. The second support column comprises an upper segment 114 formed at the bottom of the top plate 11 and a lower segment 123 formed at the top of the bottom plate 12. The lower segment 123 is connected to the lower inner side plate 1211 through a plurality of first rib plates 1213 and second rib plates 126, to enhance the stability of the lower segment 123. An upper end of the lower segment 123 is formed with a positioning groove 1231 to receive a lower end of the upper segment 114. The positioning groove 1231 facilitates positioning and mounting of the upper segment 114 and the lower segment 123. A bolt hole 1141 is provided inside the upper segment 114 by bridging, a bolt hole 1232 is provided inside the lower segment 123 by bridging, and a bolt passes through the bolt hole 1141 and is connected to the bolt hole 1232 by threads. The top plate 11 and bottom plate 12 of the shell 1 are fixedly connected by fixing the upper segment 114 and the lower segment 123. The position where the bottom plate 12 is connected to the first support column 122 and the lower segment 123 is recessed downwards and in contact with the ground, so that the first support column 122 and the lower segment 123 bear gravity and then come into contact with the ground through the bottom plate 12, thereby preventing deformation of the bottom plate 12 bearing excessive gravity.

The resistance mechanism 2 comprises a mounting seat 21, a magnetic powder brake 22, an elastic member, and a winding and storage wheel 24. The mounting seat 21 is made of metal, and the mounting seat 21 comprises a mounting plate 211, two connecting plates 212 that bend and extend upwards from two sides of the mounting plate 211, and two fixing plates 213 that extend outwards from upper edges of the two connecting plates. The fixing plates 213 are fixedly connected to the upper metal support plate 13 by bolts. The magnetic powder brake 22 comprises a brake body 221 and an output shaft 222. The brake body 221 is fixed on the top of the mounting plate 211 by bolts, and the output shaft 222 passes through the mounting plate 211 and extends downwards. The mounting plate 21 is provided with a third avoidance hole 214 through which the output shaft 222 passes. The winding and storage wheel 24 is rotatably arranged on the output shaft 222 through a one-way bearing 245, and the winding and storage wheel 24 is provided with a bearing hole 246 for mounting the one-way bearing 245. One end of the tension band 3 is connected to the winding and storage wheel 24, and the other end extends out of the shell 1. When the tension band 3 is pulled out, the winding and storage wheel 24 rotates forward and drives the output shaft 222 of the magnetic powder brake 22 to rotate through the one-way bearing 245. The elastic member drives the winding and storage wheel 24 to reverse, and the tension band 3 is wound and stored on the winding and storage wheel 24. The winding and storage wheel 24 comprises a wheel portion 241 and a spring chamber 242 that are integrally formed. An annular groove 243 for winding and storing the tension band 3 is formed on a peripheral surface of the wheel portion 241. The elastic member is a spring 23, the spring 23 is mounted in the spring chamber 242, and a lower cover 244 is arranged at the bottom of the spring chamber 242. A metal bottom cover 124 is fixed on the bottom plate 12 by bolts, the metal bottom cover 124 is provided with a limit portion 1241, the bottom plate 12 is provided with a bottom cover hole 125 through which the limit portion 1241 passes, and the limit portion 1241 passes through the bottom cover hole 125 and enters the interior of the shell 1. A fixed shaft 25 is arranged in the spring chamber 242, and a limit ring 2441 is arranged on the lower cover 244. The limit ring 2441 enables a portion of the fixed shaft 25 to pass through the lower cover 244 and connect to the limit portion 1241. The bottom of the fixed shaft 25 is provided with a limit hole 251 adapted to the limit portion 1241. The fixed shaft 25 is inserted into the limit portion 1241 through the limit hole 251, so that the fixed shaft 25 is fixed and cannot rotate. An outer end 231 of the spring 23 is fixedly connected to the spring chamber 242, and an inner end 252 of the spring 23 is fixedly connected to the fixed shaft 25. When the tension band 3 is pulled out, the tension band 3 drives the winding and storage wheel 24 to rotate, and the winding and storage wheel 24 drives the spring 23 to rotate. Because the fixed shaft 25 cannot rotate, the spring 23 produces an elastic force when rotating. The elastic force enables the spring 23 to rotate, and the spring 23 drives the winding and storage wheel 24 to rotate, thereby winding the tension band 3 back into the annular groove 243.

A grip 31 is arranged at one end, pulled out of the shell 1, of the tension band 3. The grip 31 is composed of a hollow cylinder 311 and a foam pad 312 covering a peripheral surface of the hollow cylinder 311. The hollow cylinder 311 may be made of plastic or metal to ensure comfort in use. A belt 32, a semicircular iron ring 33, and a climbing hook 34 are arranged between the hollow cylinder 311 and the tension band 3. The belt 32 passes through the hollow cylinder 311, two ends of the belt 32 fit and are connected to the semicircular iron ring 33, and the semicircular iron ring 33 is connected to the tension band 3 through the climbing hook 34. When the grip 31 is used to pull the tension band 3, the belt 32 is roughly triangular.

The climbing hook 34 facilitates connection, assembly and disassembly.

A guide assembly 26 comprises a first wheel seat 261, a second wheel seat 262, a first guide wheel 263, and a second guide wheel 264. The first wheel seat 261 is fixedly mounted at the bottom of the mounting plate 211, the second wheel seat 262 is fixedly mounted in the shell 1, the first guide wheel 263 is rotatably mounted between the first wheel seat 261 and the mounting plate 211 through a wheel axle 265, and the wheel axle 265 is vertically arranged. The first wheel seat 261 and the mounting plate 211 are provided with a wheel axle hole 2651 adapted to the wheel axle 265. The second guide wheel 264 is rotatably mounted on the second wheel seat 262 through a wheel axle 265, and the wheel axle 265 is horizontally arranged. The second wheel seat is provided with a wheel axle hole 2651 adapted to the wheel axle 265. The first guide wheel 263 guides the tension band 3 to horizontally enter into the second guide wheel 264, and the second guide wheel 264 guides the tension band 3 to pass through the shell 1. The tension band 3 that extends out from the resistance mechanism 2 is guided by the first guide wheel 263 and the second guide wheel 264 in sequence, and finally extends out of the shell 1, so that the tension band 3 is pulled out of the shell 1 from the resistance mechanism 2 more smoothly without entanglement or knotting. The top plate 11 is provided with a second avoidance hole 115 through which the tension band extends out, and the upper metal support plate 13 is further provided with a hole 131 through which the tension band passes and an annular bearing seat 132 surrounding the hole 131.

The joint bearing 15 comprises an outer ring 151 matched with the annular bearing seat 132 and a ball 152 rotatably arranged in the outer ring 151. The ball 152 is formed with a fourth avoidance hole 153 through which the tension band 3 passes. The tension band 3 passes through the second avoidance hole 115 after being pulled out of the guide mechanism 26, then passes through the hole 131 and the fourth avoidance hole 153, and is pulled out of the shell 1. In this case, when the tension band 3 is pulled in any direction, the ball 152 can adapt to the pulling direction of the tension band 3 and rotate, so that the tension band 3 can be smoothly pulled out or retracted, the friction between the tension band 3 and the fourth avoidance hole 153 is reduced, and the service life of the tension band 3 is prolonged.

A controller 4 connected to the magnetic powder brake 22 is arranged at the top of the shell 1, the controller 4 comprises a display screen, and the controller 4 is fixed to the bottom of the top plate 11 by bolts.

The controller 4 can also display exercise time for the user to record exercises and develop an exercise plan.

During exercise, the user steps on the upper metal support plate 13 or the top plate 11, adjusts the resistance of the resistance mechanisms 2 through the controller 4, and overcomes the resistance of the resistance mechanisms 2 to pull the tension band 3 out of the shell 1. When the user performs tension exercise, the support frame serves as a main stressed component, and the upper metal support plate 13 and the support mechanism cooperate to stably support human weight, so as to prevent the product from being trampled.

The two second metal profiles 82 can be vertically supported between two short edges of the upper metal support plate 84 and the lower metal support plate 83 by welding or bolts, respectively. The second metal profiles 82 comprise two parallel and opposite long plates and a connecting plate connected between the two long plates. A guide assembly 66 for guiding the tension band 7 is mounted between the two long plates. The second metal profiles 82 can further improve the strength of the support frame, and using the second metal profiles 82 to mount the guide assembly 66 can improve the mounting strength of the guide assembly 66, so that the guide assembly 66 can stably guide the tension band 7.

The resistance mechanism 6 comprises a mounting seat 61, a magnetic powder brake 62, an elastic member, and a winding and storage wheel 64. The mounting seat 61 is made of metal, and the mounting seat 61 comprises a mounting plate 611, two connecting plates 612 that bend and extend upwards from two sides of the mounting plate 611, and two fixing plates 613 that extend outwards from upper edges of the two connecting plates 612. The fixing plates 613 are fixedly connected to the upper metal support plate 84 by bolts. The magnetic powder brake 62 comprises a brake body 621 and an output shaft 622. The brake body 621 is fixed on the top of the mounting plate 611 by bolts, and the output shaft 622 passes through the mounting plate 611 and extends downwards. The mounting plate 61 is provided with a third avoidance hole 614 through which the output shaft 622 passes. The winding and storage wheel 64 is rotatably arranged on the output shaft 622 through a one-way bearing 645, and the winding and storage wheel 64 is provided with a bearing hole 646 for mounting the one-way bearing 645. One end of the tension band 7 is connected to the winding and storage wheel 64, and the other end extends out of the shell 5. When the tension band 7 is pulled out, the winding and storage wheel 64 rotates forward and drives the output shaft 622 of the magnetic powder brake 62 to rotate through the one-way bearing 645. The elastic member drives the winding and storage wheel 64 to reverse, and the tension band 7 is wound and stored on the winding and storage wheel 64. The winding and storage wheel 64 comprises a wheel portion 641 and a spring chamber 642 that are integrally formed. An annular groove 643 for winding and storing the tension band 7 is formed on a peripheral surface of the wheel portion 641. The elastic member is a spring 63, the spring 63 is mounted in the spring chamber 642, and a lower cover 644 is arranged at the bottom of the spring chamber 642. A metal bottom cover 524 is fixed on the bottom plate 52 by bolts, the metal bottom cover 524 is provided with a limit portion 5241, the bottom plate 52 is provided with a bottom cover hole 525 through which the limit portion 5241 passes, and the limit portion 5241 passes through the bottom cover hole 525 and enters the interior of the shell 5. A fixed shaft 65 is arranged in the spring chamber 642, and a limit ring 6441 is arranged on the lower cover 644. The limit ring 6441 enables a portion of the fixed shaft 65 to pass through the lower cover 644 and connect to the limit portion 5241. The bottom of the fixed shaft 65 is provided with a limit hole 651 adapted to the limit portion 5241. The fixed shaft 65 is inserted into the limit portion 5241 through the limit hole 651, so that the fixed shaft 65 is fixed and cannot rotate. An outer end 631 of the spring 63 is fixedly connected to the spring chamber 642, and an inner end 652 of the spring 63 is fixedly connected to the fixed shaft 65. When the tension band 7 is pulled out, the tension band 7 drives the winding and storage wheel 64 to rotate, and the winding and storage wheel 64 drives the spring 63 to rotate. Because the fixed shaft 65 cannot rotate, the spring 63 produces an elastic force when rotating. The elastic force enables the spring 63 to rotate, and the spring 63 drives the winding and storage wheel 64 to rotate, thereby winding the tension band 7 back into the annular groove 643.

A grip 71 is arranged at one end, pulled out of the shell 5, of the tension band 7. The grip 71 is composed of a hollow cylinder 711 and a foam pad covering a peripheral surface of the hollow cylinder 711. The hollow cylinder 711 may be made of plastic or metal to ensure comfort in use. A belt 72, a semicircular iron ring 73, and a climbing hook 74 are arranged between the hollow cylinder 711 and the tension band 7. The belt 72 passes through the hollow cylinder 711, two ends of the belt 72 are connected to the semicircular iron ring 73, and the semicircular iron ring 73 is connected to the tension band 7 through the climbing hook 74. When the grip 71 is used to pull the tension band 7, the belt 72 is roughly triangular. The triangular structure design can concentrate the force on the grip 71 at one point of the triangle, which facilitates pulling the tension band 7. The climbing hook 74 facilitates connection, assembly and disassembly.
