Further illustration of the present invention is provided below, in conjunction with the accompanying drawings and examples.
The following are only preferred embodiments of the present invention, and should not limit the scope of the invention.
As shown in
In specific use, the user clamps the pipe body 01 through the pipe holding mechanism 2, then places the corresponding model of the joint 02 into the joint locating fixture 4, and installs the joint locating fixture 4 into the internal space 300 of the carrier 3. The power component 5 drives the carrier 3 to approach the pipe holding mechanism 2, enabling the joint 02 held in the joint locating fixture 4 to connect to the end of the pipe body 01 held by the pipe holding mechanism 2. Its structural design is simple and can achieve a quick connection between the joint 02 and the pipe body 01. Generally speaking, the pipe body 01 refers to a hose for conveying fluid. Depending on the size of the hose nozzle, different specifications of the joint 02 need to be assembled. This invention sets a detachable joint locating fixture 4, which can be used in combination with the carrier 3, to realize the rapid assembly of various models of pipe body 01 and joint 02, making it very convenient for the user to operate.
In a feasible implementation scheme, as shown in
In this embodiment, the pipe holding mechanism 2 includes a fixed seat 20 fixed on the main body 1, two positioning seats 21 sliding on the fixed seat 20, and a transmission component 22. The two positioning seats 21 are arranged symmetrically on the left and right, and the transmission component 22 is transmissionally connected to each of the positioning seats 21. The transmission component 22 can drive the two positioning seats 21 to approach each other to clamp the pipe body 01.
Each of the positioning seats 21 includes a slider 210, a pipe clamp 211, and a locking component 212. The slider 210 is slidably mounted on the fixed seat 20. The pipe clamp 211 is fixedly connected to the slider 210 through the locking component 212, and the pipe clamp 211 has a pipe clamping groove 2110.
Specifically, the transmission component 22 is drivingly connected to the slider 210.
The pipe clamping groove 2110 of the pipe clamp 211 is shaped with corrugated teeth 2111 corresponding to the corrugated structure of the pipe body 01.
In specific use, first place the pipe body 01 between the pipe clamping grooves 2110 of the two pipe clamps 211, and then use the transmission component 22 to drive the two sliders 210 to approach each other to clamp the pipe body 01. Furthermore, setting corrugated teeth 2111 in the pipe clamp 211 that correspond to the corrugated structure of the pipe body 01 can further enhance the clamping force and prevent the pipe body 01 from rotating or falling off.
In this embodiment, the transmission component 22 includes a bidirectional screw 220 rotationally mounted on the fixed seat 20 and a rotating handle 221 mounted on the end of the bidirectional screw 220. The bidirectional screw 220 has a forward thread portion 2200 and a reverse thread portion 2201. Each of the positioning seats 21 is provided with a first threaded hole 2100. The first threaded hole 2100 of one positioning seat 21 is transmissionally connected to the forward thread portion 2200 of the bidirectional screw 220, and the first threaded hole 2100 of the other positioning seat 21 is transmissionally connected to the reverse thread portion 2201 of the bidirectional screw 220.
When installing the pipe, the user rotates the rotating handle 221, thereby driving the bidirectional screw 220 to rotate. The rotating bidirectional screw 220 brings the two positioning seats 21 closer together through the forward thread portion 2200 and the reverse thread portion 2201.
In this embodiment, the carrier 3 includes a main shell 30, a split shell 31 hinged to the main shell 30, and a locking part 32 mounted on the main shell 30. The main shell 30 has a first split groove 3000. The split shell 31 has a second split groove 3001. The first split groove 3000 and the second split groove 3001 are combined to form the internal space 300 of the carrier 3. The split shell 31 can be opened or locked relative to the main shell 30, and the locking part 32 is used to open or lock the split shell 31 relative to the main shell 30 for the joint locating fixture 4 to be put in or taken out.
In a feasible embodiment, the locking part 32 includes a reset elastic component 320 and a locking plug 321. The main shell 30 has a first column hole 301, a locking slot 302 communicating with the first column hole 301, and a second column hole 303 communicating with the locking slot 302. The split shell 31 has a buckle foot 310 that can extend into the locking slot 302. One end of the locking plug 321 is equipped with a stop part 3210 for keeping the buckle foot 310 inside the locking slot 302. The reset elastic component 320 is located in the second column hole 303. The end of the locking plug 321 with the stop part 3210 passes through the first column hole 301, the locking slot 302, and extends into the second column hole 303, pushing against the reset elastic component 320. The other end of the locking plug 321 is exposed at the first column hole 301.
In the initial state, the split shell 31 and the main shell 30 maintain a locked state. At this time, the buckle foot 310 of the split shell 31 remains in the locking slot 302. When it is necessary to load the joint locating fixture 4 into the internal space 300, the user only needs to hold the locking plug 321, making the stop part 3210 of the locking plug 321 fully extend into the second column hole 303. This unlocks the stop action of the stop part 3210 on the buckle foot 310, which can make the split shell 31 open relatively. Its structure design is compact and very convenient for user operation.
In this embodiment, the joint locating fixture 4 includes two positioning blocks 40 that are set in halves and are relatively independent. Each positioning block 40 has a positioning groove 41. The two positioning blocks 40 are assembled in pairs and used in combination. After the positioning grooves 41 of the two positioning blocks 40 are combined, they form a positioning space 400 for clamping the joint 02. The type of joint locating fixture 4 also corresponds to various specifications. The size of the positioning groove 41 of each corresponding type of joint locating fixture 4 is consistent with the international standard size of the joint 02, which positions the joint 02.
In a more specific implementation plan, one end of each positioning block 40 far from the positioning groove 41 is configured as an opening. The inner wall of the opening is provided with an internal thread part 401. Generally speaking, inside the main body clamping mechanism 2 of the pipe body 01, the connecting end of the pipe body 01 extends to the opening of the positioning block 40. By setting the internal thread part 401, the worn and mixed threads at the connecting end of the pipe body 01 (like the mixed braided threads often appearing after the cutting wear of the braided hose end) can be better guided into the opening, so that the connecting end of the pipe body 01 is completely wrapped inside the joint 01.
In this embodiment, the power member 5 includes a base 50, a rotary screw 51, and a power handle 52. The base 50 has a second threaded hole 500. The rotary screw 51 is rotatably assembled in the second threaded hole 500 of the base 50. One end of the rotary screw 51 is fixedly connected with the carrier 3, and the other end of the rotary screw 51 is fixedly connected with the power handle 52. The power handle 52 can drive the carrier 3 towards the pipe holding mechanism 2 through the rotary screw 51, so that the joint 02 is screwed into the end of the pipe body 01. The user can drive the rotary screw 51 to screw in or out clockwise through the power handle 52 to achieve the carrier 3 moving towards or away from the pipe holding mechanism 2.
The above content is only the preferred embodiment of the present invention. For those skilled in the art, according to the idea of the present invention, there will be changes in specific implementation methods and application ranges. The contents of this specification should not be construed as limiting the invention.
