[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 4 This utility model provides a quick-connect clamp: It includes a first clamp 1, with two support plates 13 symmetrically telescopically connected to both sides of the end face of the first clamp 1. A first limiting member is provided on each side of the first clamp 1, and the two first limiting members are respectively connected to the two support plates 13. A second clamp 3 is hinged to the top surface of each of the two support plates 13, and the two second clamps 3 are fixed to each other by the second limiting members. A first rubber sheet 2 is fixedly connected to the inner side of the first clamp 1, and a second rubber sheet 11 is fixedly connected to the inner side of each of the two second clamps 3. Two slots 18 are symmetrically provided on the end face of the first clamp 1, and a plug 20 is inserted into each slot 18. The wall is symmetrically provided with two sliding grooves 24, and a slider 26 is slidably connected in each sliding groove 24. The two sliders 26 are fixed on both sides of the insert 20. A spring 25 is fixed between the inner wall of each sliding groove 24 and the slider 26. The two inserts 20 are fixed on the bottom surface of the two support plates 13. The first limiting member rotates through the slot 18 and is threadedly connected to the insert 20. The end of the second clamp 3 is fixedly connected to the second connecting block 15. The front side of the second connecting block 15 passes through the through hole 17. The support shaft 16 is rotatably sleeved in the through hole 17. A first connecting block 14 is fixed at both ends of the support shaft 16. The two first connecting blocks 14 are symmetrically fixed on the top surface of the support plate 13.

[0022] The first limiting member includes an external threaded block 19 that is threadedly connected to the insert block 20. The side of the insert block 20 is provided with a first threaded groove 21. The external threaded block 19 is threadedly connected in the first threaded groove 21. The inner wall of one side of the slot 18 is provided with a second threaded groove 22. A connecting rod 23 is movably connected in the second threaded groove 22. One end of the connecting rod 23 is fixedly connected to the external threaded block 19, and the other end is fixedly connected to the rotating block 12.

[0023] The second limiting component includes a first fixing block 10 and a second fixing block 9. The first fixing block 10 and the second fixing block 9 are respectively fixedly connected to two second clamps 3. The top surface of the second fixing block 9 is provided with a rotating groove 7. A support block 8 is rotatably connected in the rotating groove 7. A bolt 4 is fixedly connected to the end of the support block 8. The top surface of the first fixing block 10 is provided with a slot 6. The outer edge of the bolt 4 is engaged in the slot 6. A nut 5 is threaded on the outer edge of the bolt 4. The nut 5 abuts against the side of the first fixing block 10.

[0024] By using the insert block 20 and slider 26 and spring 25 to telescopically connect the support plate 13 in the slot 18 on the end face of the first clamp 1, the second clamp 3 is hinged to the top surface of the support plate 13, and the insert block 20 is fixed to the first clamp 1 by the first limiting member. This makes it easier to fix the clamp to the pipe fitting, avoiding the problem of bolts 4 and nuts 5 getting stuck when fixing the clamp to the pipe fitting with a pair of bolts 4 and nuts 5, thereby improving the convenience of installing the clamp to the pipe fitting.

[0025] Working principle: In use, first open the two second clamps 3 outwards, then lower the two second clamps 3 to engage the first clamp 1 on the upper edge of the pipe fitting, so that the first rubber sheet 2 is attached to the outer edge of the pipe fitting. Then close one of the second clamps 3 upwards, so that the second rubber sheet 11 inside the second clamp 3 is attached to the lower edge of the pipe. When closing the second clamp 3 upwards, the second rubber sheet 11 and the first rubber sheet 2 obstruct the second clamp 3, causing the corresponding support plate 13 to move downwards. When the support plate 13 moves downwards, the spring 25 is compressed, and the support plate 13 causes the insert block 20 to move slightly within the slot 18, so that the insert block 20 slightly moves within the slot 18. Then press the first clamp 1 and the second clamp 3, so that the insert block 20 returns to the slot. Inside the groove 18, the compressed spring 25 is reset, causing the first rubber sheet 2 and the second rubber sheet 11 to fit tightly against the outer edge of the pipe fitting. At this time, the first threaded groove 21 and the second threaded groove 22 are aligned. Then, the rotating block 12 is rotated, and the rotating block 12 drives the external threaded block 19 to rotate through the connecting rod 23, so that the external threaded block 19 moves from the second threaded groove 22 to the first threaded groove 21 of the insert block 20 to fix the second clamp 3. Then, the same operation steps are taken to fix the other second clamp 3 to the first clamp 1. Then, by flipping the support block 8, the support block 8 drives the bolt 4 to engage in the groove 6 of the first fixing block 10. Then, the nut 5 is rotated so that the nut 5 abuts against the outside of the first fixing block 10 to fix the two merged second retaining rings.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
