The present invention relates to a claw power supply structure, and more particularly to a claw equipped with a flexible cable having suspension and power supply functions, which achieves the effects of simplified structure, more durability and easier manipulation.
A conventional claw machine, as shown in
1. When the claw 15 moves back and forth and moves up and down, the elastic spiral cable 19 is extended, retracted and shaken on and on. The elastic spiral cable 19 constantly rubs against the periphery of the wire hole 21, which makes the elastic spiral cable 19 easy to wear and tear. After a period of time, because of bending back and forth, the inner wires 20 of the elastic spiral cable 19 may be broken to cause malfunction of the claw 5.
2. When the player manipulates the claw 15 to catch an article, the shaking elastic spiral cable 19 will affect the player's line of sight, hinder judgment in the position to catch the article, and make the claw 15 be in a skewed state with uneven center of gravity. This will reduce the enthusiasm and interest of players.
3. When the elastic spiral cable 19 is displaced along with the horizontal moving seat 13 and the claw 15, the shaking elastic spiral cable 19 may be entangled with the article. The traveling horizontal moving seat 13 makes the article and the elastic spiral cable 19 being pulled each other and may damage the inner wires 20.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to solve the aforesaid problems and to provide a claw power supply structure, which has better and more practical effects. The claw is suspended by a flexible cable, and the flexible cable supplies power to the claw. The claw is in a catch state when it is energized, or it is not in a catch state when it is not energized. The flexible cable will not be rubbed or pulled, achieving the effects of simplified structure and more durability.
In order to achieve the foregoing object, a claw power supply structure is provided. The claw power supply structure comprises a moving seat and a claw. The moving seat includes a base and a reel pivoted to the base. Both sides of a periphery of the reel have a pair of flanges. A pair of electrically conductive rings is provided on respective sides of the two flanges, facing away from each other. The base includes an electrically conductive plate bracket with a power supply, two electrically conductive plates that extend from the electrically conductive plate bracket and are in contact with the respective electrically conductive rings, and a flexible cable having at least two inner wires wound on the reel. The flanges each have a perforation. First ends of the inner wires of the flexible cable are inserted through the perforations of the flanges and connected to the electrically conductive rings, respectively. Second ends of the inner wires of the flexible cable are connected to a top of the claw. The claw includes a drive member. The drive member includes an outer cylinder. The outer cylinder has an accommodation groove therein. An electromagnetic coil is provided in the accommodation groove. A top of the outer cylinder is covered with a top cover. The top cover has a central through hole. The flexible cable passes through the central through hole, and the inner wires of the flexible cable are electrically connected to the electromagnetic coil.
In one embodiment of the present invention, the base further includes a power connection bracket and a power connection cable connected between the power connection bracket and the electrically conductive plate bracket.
In one embodiment of the present invention, the perforations of the flanges are located on inner peripheries of the respective electrically conductive rings.
In one embodiment of the present invention, an outer layer of the flexible cable is made of PVC (polyvinyl chloride), PUR (polyurethane) or TPE (thermoplastic elastomer) to cover the inner wires.
With the above-mentioned structure, the flexible cable will not be rubbed or pulled and will not obstruct the player's line of sight, achieving the effects of simplified structure, more durability and easier manipulation.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
Referring to
The moving seat 30 includes a vertical base 31 and a motor 32 on the base 31. The motor 32 is configured to drive a reel 33 pivoted to the base 31 to rotate. Both sides of the periphery of the reel 33 have a pair of flanges 331. A pair of electrically conductive rings 34 is provided on the sides of the two flanges 331, facing away from each other. The base 31 includes a power connection bracket 35, an electrically conductive plate bracket 36, two electrically conductive plates 37 that extend from the electrically conductive plate bracket 36 and are in contact with the respective electrically conductive rings 34, a power connection cable 38 connected between the power connection bracket 35 and the electrically conductive plate bracket 36 for the two electrically conductive plates 37 to be energized to form a power supply, and a flexible cable 39 having at least two inner wires 391 wound on the reel 33. The flanges 331 each have a perforation 332 on the inner edges of the two electrically conductive rings 34. The first ends of the inner wires 391 of the flexible cable 39 are inserted through the perforations 332 and connected to the electrically conductive rings 34, respectively. The second ends of the inner wires 391 of the flexible cable 39 are connected to the top of the claw 40.
The claw 40 includes a drive member 41, a ferromagnetic moving rod 43, and a plurality of fingers 42 driven by the ferromagnetic moving rod 43. The drive member 41 includes an outer cylinder 44. The outer cylinder 44 has an accommodation groove 45 therein. A pipe 46 having an axial hole 47 is provided inside the accommodation groove 45. An electromagnetic coil 48 is sleeved on the outer periphery of the pipe 46. A magnetically conductive member 49 is provided on the top of the axial hole 47 of the pipe 46. The top of the outer cylinder 44 is covered with a top cover 50. The top cover 50 has a central through hole 51. The flexible cable 39 passes through the central through hole 51, and the inner wires 391 are electrically connected to the electromagnetic coil 48. The ferromagnetic moving rod 43 movably passes through the bottom of the accommodation groove 45 and the bottom of the pipe 46 and is inserted in the axial hole 47. When the flexible cable 39 and the electromagnetic coil 48 are energized, the magnetically conductive member 49 generates a magnetic force to attract the ferromagnetic moving rod 43 for the fingers 42 to be in a catch state. When the flexible cable 39 and the electromagnetic coil 48 are not energized, the magnetically conductive member 49 does not generate a magnetic force and releases the ferromagnetic moving rod 43 for the fingers 42 to be in a release state. With the above-mentioned structure, the flexible cable 39 supplying power to the claw 40 will not be rubbed or pulled and will not obstruct the player's line of sight, achieving the effects of simplified structure, more durability and easier manipulation.
