Description

Technical Field

[0001] This utility model relates to the field of water supply pipeline connection technology, and in particular to a quick connection device for water supply pipelines. Background Technology

[0002] Water supply pipes can be divided into metal pipes, composite pipes, and plastic pipes. Metal pipes are mainly divided into copper pipes and stainless steel pipes. Metal pipes are safe, hygienic, and durable, making them the ideal water pipes for home renovation. A typical example of composite pipes is aluminum-plastic composite pipes, but they have been gradually phased out due to their thermal expansion and contraction. A typical example of plastic pipes is PPR water pipes, which have advantages such as safety, non-toxicity, easy installation, and low price, making them the most commonly used water pipes in home renovation. During the construction of water supply pipes, connecting devices are often needed to connect the pipes to ensure normal water supply.

[0003] Currently, there are many ways to connect water supply pipes. Traditional connection methods mostly require the use of tools for reinforcement, which cannot quickly connect water supply pipes and is a waste of time and manpower. To address this, we propose a quick connection device for water supply pipes to solve the above problems. Utility Model Content

A threaded hole is opened on the front side of the limiting frame. A bearing is fixedly embedded on the front side of the movable block. A threaded rod is fixedly installed on the inner ring of the bearing. The outer surface of the threaded rod is threadedly connected to the inner wall of the threaded hole. A knob is fixedly installed at the front end of the threaded rod.

[0007] In a further embodiment, a first connecting block is fixedly installed on the inner wall of the connector, and a first limiting groove is provided on the back of the first connecting block, and the front of the fixing block is in contact with the inner wall of the first limiting groove.

[0008] In a further embodiment, a second connecting block is fixedly installed on the inner wall of the connector, and a second limiting groove is provided on the front side of the second connecting block, and the back side of the movable block is in contact with the inner wall of the second limiting groove.

[0009] In a further embodiment, a first water supply pipe is provided on the outside of the connector, and a first annular block is fixedly installed on the outer surface of the left end of the first water supply pipe.

[0010] In a further embodiment, a second water supply pipe is provided on the outside of the connector, and a second annular block is fixedly installed on the outer surface of the right end of the second water supply pipe.

[0011] In a further embodiment, the inner wall of the connector is provided with an annular groove, and the outer surfaces of the first annular block and the second annular block are in contact with the inner wall of the annular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device can conveniently limit the connection between the first and second water supply pipes by opening an annular groove on the inner wall of the connector. By threading the outer surface of the threaded rod to the inner wall of the threaded hole and installing a knob at the front end of the threaded rod, the operator can easily adjust the position of the moving block by turning the knob. Through the cooperation of the fixed block, the moving block, the first limiting groove and the second limiting groove, the first connecting block and the second connecting block can be easily squeezed together, so that the device can quickly connect the water supply pipes together.

[0022] Please see Figure 1-4In this utility model, a quick connection device for water supply pipes includes a connector 2, a limiting frame 5, and a moving block 9. A fixing block 11 is fixedly installed on the inner wall of the limiting frame 5, and a threaded hole 15 is opened on the front side of the limiting frame 5. A bearing 14 is fixedly embedded on the front side of the moving block 9, and a threaded rod 10 is fixedly installed on the inner ring of the bearing 14. The outer surface of the threaded rod 10 is threadedly connected to the inner wall of the threaded hole 15, and a knob 4 is fixedly installed at the front end of the threaded rod 10. By embedding the bearing 14 on the front side of the moving block 9 and fixing the rear end of the threaded rod 10 to the inner ring of the bearing 14, the threaded rod 10 can rotate freely. By installing the knob 4 at the front end of the threaded rod 10, the operator can easily rotate the threaded rod 10. By threading the outer surface of the threaded rod 10 to the inner wall of the threaded hole 15, the operator can easily adjust the position of the moving block 9.

[0023] A first connecting block 8 is fixedly installed on the inner wall of the connector 2. A first limiting groove 12 is provided on the back of the first connecting block 8. The front of the fixing block 11 contacts the inner wall of the first limiting groove 12. By contacting the front of the fixing block 11 with the inner wall of the first limiting groove 12, the fixing block 11 can play a certain limiting role on the first connecting block 8. A second connecting block 6 is fixedly installed on the inner wall of the connector 2. A second limiting groove 13 is provided on the front of the second connecting block 6. The back of the moving block 9 contacts the inner wall of the second limiting groove 13. By contacting the back of the moving block 9 with the inner wall of the second limiting groove 13, the moving block 9 can play a certain limiting role on the second connecting block 6. When the moving block 9 moves continuously, it can gradually squeeze the second connecting block 6 toward the first connecting block 8.

[0024] The connector 2 has a first water supply pipe 1 on its exterior. A first annular block 17 is fixedly installed on the outer surface of the left end of the first water supply pipe 1. The connector 2 has a second water supply pipe 3 on its exterior. A second annular block 7 is fixedly installed on the outer surface of the right end of the second water supply pipe 3.

The connector 2 has an annular groove 16 on its inner wall. The outer surfaces of the first annular block 17 and the second annular block 7 are in contact with the inner wall of the annular groove 16. By opening the annular groove 16 on the inner wall of the connector 2 and contacting the outer surfaces of the first annular block 17 and the second annular block 7 with the inner wall of the annular groove 16, the connector 2 can firmly fix the first annular block 17 and the second annular block 7 together.

[0025] The working principle of this utility model is as follows:

[0026] First, the worker aligns the right end of the first water supply pipe 1 with the left end of the second water supply pipe 3. Then, the worker places the connector 2 on the outer surface of the first annular block 17 and the second annular block 7, and makes the front of the fixing block 11 contact the inner wall of the first limiting groove 12. Then, the worker rotates the knob 4, which drives the threaded rod 10 to rotate. Through the engagement of the threaded rod 10 with the threaded hole 15 and the bearing 14 with the threaded rod 10, the rotation of the threaded rod 10 drives the moving block 9 to move. When the back of the moving block 9 contacts the inner wall of the second limiting groove 13, the worker continues to rotate the knob 4. When the moving block 9 presses the second connecting block 6 and the first connecting block 8 together, the first water supply pipe 1 and the second water supply pipe 3 can be quickly connected together.
