Detailed Implementation
[0021] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0022] Example 1:
[0023] like Figures 1 to 2 As shown, this utility model provides a plumbing pipe splicing device, including a pipe body 1, and further comprising:
[0024] Connector 2 is disposed on the pipe body 1, and there is an interference fit between connector 2 and the inner wall of pipe body 1;
[0025] Pressure ring 3 is located on the outside of the pipe body 1. The pressure ring 3 and the connector 2 cooperate with each other to press the pipe body 1 located between them.
[0026] The drive assembly abuts against the pressure ring 3. The output end of the drive assembly is connected to a drive unit. The drive assembly drives the drive unit to push the pressure ring 3 along the pipe body 1 to complete the compression and sealing of the pipe body 1.
[0027] In use, first insert the connector 2 into the inner wall of the pipe fitting and lock it in place. Then, put the pressure ring 3 on the outside of the pipe fitting and use the drive assembly to push the pressure ring 3 to move until the pressure ring 3 moves to a position that is aligned with the connector 2 on the inner wall of the pipe fitting. This allows the pressure ring 3 and the connector 2 to press the middle pipe fitting tightly, eliminating the troublesome steps of traditional installation, ensuring that the interface will not leak, and solving the problem of quick installation and sealing between pipe fittings.
[0028] Example 2:
[0029] like Figures 1 to 2 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, there are two connectors 2, and both ends of the connectors 2 can be inserted into the pipe body 1. The connectors 2 adopt a double-headed structure, and both ends can be inserted into the pipe body 1 for splicing. One connector 2 can connect two pipes at the same time. In use, simply insert both ends of the connector 2 into the two pipes to be spliced, and then apply pressure with the external pressure ring 3 and the drive assembly to firmly fix the two pipes together.
[0030] Furthermore, there are two pressure rings 3, located on either side of the connection point of the pipe body 1, and the pressure rings 3 are slidably connected to the pipe body 1. In use, first, place the two pressure rings 3 onto the pipes to be connected. After the middle connector 2 is inserted and aligned, push the two pressure rings 3 towards the center using the drive assembly. Because the pressure rings 3 are slidably connected, their positions can be flexibly adjusted during installation to ensure they precisely press against the joint between the pipe body and the connector 2. This results in more even force distribution during tightening, better sealing, and easy movement during assembly and disassembly without jamming.
[0031] Furthermore, the drive assembly includes a mounting part 4. A first fixing block 5 is fixedly mounted on one end of the bottom surface of the mounting part 4, and a second fixing block 6 is slidably mounted on the other end of the mounting part 4. A movable block 7 is fixedly mounted on the second fixing block 6. A sliding groove is provided inside the mounting part 4, and the movable block 7 is slidably connected to the sliding groove. In use, the fixing block is first pressed against the pressure ring 3, and then the movable block 7 is slid in the sliding groove by operating the handle 12. In this way, the second fixing block 6 will push the pressure ring 3 to move towards the center, pressing the pipe tightly onto the connector 2. The two fixing blocks, one fixed and one movable, are guided by the sliding groove to make the movement smoother, ensuring that the pressure ring 3 can firmly press the pipe, which is both labor-saving and reliable.
[0032] Furthermore, a groove 8 is provided on the top surface of the mounting part 4, and a drive handle 9 is hingedly installed in the groove 8. A connecting rod 10 is hingedly installed on one side of the groove 8, and a spring 11 connects the connecting rod 10 and the drive handle 9. A handle 12 is fixedly installed on the mounting part 4. When it is necessary to tighten the pipe fitting, simply hold the handle 12 and turn the drive handle 9. It will act like a lever, driving the moving block 7 to slide through the connecting rod 10. The function of the spring 11 is to make the operation of the drive handle 9 easier and to automatically return it to its original position.
[0033] Furthermore, the movable block 7 is evenly provided with several locking slots 13, and a drive block 14 that matches the locking slot 13 is fixedly installed on one end of the drive handle 9. When the drive handle 9 is turned, the drive blocks 14 will engage one after another in the slots of the movable block 7 like gear teeth, driving the movable block 7 to move forward step by step. This ratchet-like structure allows the pressure ring 3 to be tightened in segments. Each time the drive handle 9 is turned, it moves forward one step, which can precisely control the tightening force and prevent rebound.
[0034] Furthermore, several annular grooves 15 are formed on the outer side of the connector 2. When the connector 2 is inserted into the pipe, these annular grooves 15 serve multiple functions. First, they increase the contact area, allowing the inner wall of the pipe to fit the connector 2 more tightly. Second, during the compression process, the pipe material is squeezed and embedded into these grooves 8, forming an anti-slip texture-like effect to prevent the connector 2 from loosening. Finally, they can store a small amount of sealing material to further improve the sealing performance. In use, simply insert the grooved connector 2 into the pipe and then press it with the pressure ring 3, and these annular grooves 15 will naturally form multiple sealing rings.
[0035] The working principle of the plumbing pipe splicing device disclosed in this application is as follows:
[0036] In use, first insert the connector 2 into the pipe to be spliced, then put the pressure ring 3 on the corresponding position on the outside of the pipe. Operate the handle 12 to drive the drive handle 9 to rotate. The drive block 14 on the drive handle 9 will be locked into the locking groove 13 of the moving block 7, pushing the second fixing block 6 to move along the slide groove, so that the two pressure rings 3 squeeze the pipe in the middle. This squeezing action will cause the pipe body 1 to deform at the connector 2, forming a tight seal. The annular groove 15 on the outside of the connector 2 can enhance the sealing effect, and the bidirectional design of the connector 2 can realize the simultaneous insertion of pipes into both ends.
[0037] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
