Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a retractable clamp. Background Art

[0002] At present, in the connection of pipe fittings, valves and pipeline accessories, the pipes are mostly connected to quick connectors by clamps to tighten them so as to facilitate the flow of media between the pipes.

[0003] Among them, after searching, the patent with the authorization publication number CN219176709U discloses a non-slip retractable clamp. During use, the clamp of the above patent cannot adjust the width of the clamp according to the connection range of the pipe fitting, which makes the pipe fitting connection unstable, resulting in poor use of the clamp and cannot meet the pipe fitting connection application. Utility Model Content

[0004] The utility model aims to solve the problem that the existing clamp cannot be used to adjust the width of the clamp according to the connection range of the pipe during use, which makes the pipe connection unstable, resulting in poor use of the clamp and cannot meet the pipe connection use. A retractable clamp is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A telescopic clamp comprises two first half hoops and two second half hoops, wherein the first half hoops are rotatably connected to the second half hoops, and a plurality of guide rods are slidably inserted between the two first half hoops and the two second half hoops, wherein a support frame is rotatably sleeved between the two ends of the two guide rods, a threaded cylinder is rotatably connected between the inner walls at both ends of one of the support frames, and a guide cylinder is rotatably connected between the inner walls at both ends of the other support frame, a butterfly screw is slidably inserted in the guide cylinder, and the butterfly screw is threadably inserted into the threaded cylinder.

[0007] Furthermore, one end of the threaded barrel is fixedly connected with a guide cover.

[0008] Furthermore, a steel sheet is fixedly connected to the inner side of the first half hoop.

[0009] Furthermore, an arcuate groove is provided on the inner side of the second half hoop, and the steel sheet is located in the arcuate groove.

[0010] Furthermore, both ends of the guide rod are fixedly connected to limit rings.

[0011] Furthermore, a first anti-slip pad is bonded to one side of the steel sheet.

[0012] Furthermore, a second anti-slip pad is bonded to the inner sides of the first half hoop and the second half hoop.

[0013] The beneficial effects of the utility model are:

[0014] 1. By pulling the first half hoop and the second half hoop to slide on the guide rod, the width of the clamp can be adjusted according to the connection range of the pipe fitting, thereby improving the applicability of the clamp.

[0015] 2. By inserting the steel sheet into the arc groove, the contact area between the two ends of the clamp is increased, thereby improving the stability of the clamp fixation.

[0016] 3. The setting of the limiting ring can limit the two ends of the guide rod, thereby preventing the first half hoop and the second half hoop from falling off the guide rod, so as not to affect the use of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4A retractable clamp comprises two first half hoops 1 and two second half hoops 2, the first half hoops 1 and the second half hoops 2 are rotatably connected, and a plurality of guide rods 3 are slidably inserted between the two first half hoops 1 and the two second half hoops 2, and the first half hoops 1 and the second half hoops 2 are pulled to slide on the guide rods 3, so that the width of the clamp is adjusted according to the connection range of the pipe fitting, wherein a support frame 4 is rotatably sleeved between the two ends of the two guide rods 3, a threaded cylinder 5 is rotatably connected between the inner walls of the two ends of one of the support frames 4, and a guide cylinder 6 is rotatably connected between the inner walls of the two ends of the other support frame 4, a butterfly screw 7 is slidably inserted in the guide cylinder 6, and the butterfly screw 7 is threadedly inserted with the threaded cylinder 5, the butterfly screw 7 is inserted into the guide cylinder 6, and then inserted into the threaded cylinder 5 through the guide cover 8, and then the butterfly screw 7 is tightened with the threaded cylinder 5, so as to fix the clamp.

[0024] A guide cover 8 is welded to one end of the threaded tube 5, a steel sheet 9 is welded to the inner side of the first half hoop 1, and an arc groove 10 is provided on the inner side of the second half hoop 2. The steel sheet 9 is located in the arc groove 10. The steel sheet 9 is inserted into the arc groove 10 to increase the contact area between the two ends of the clamp, thereby improving the stability of the clamp fixation. Limiting rings 11 are welded to both ends of the guide rod 3, and the limiting rings 11 limit the two ends of the guide rod 3 to prevent the first half hoop 1 and the second half hoop 2 from falling off the guide rod 3. A first anti-slip pad 12 is bonded to one side of the steel sheet 9, and a second anti-slip pad 13 is bonded to the inner side of the first half hoop 1 and the second half hoop 2. The design of the first anti-slip pad 12 and the second anti-slip pad 13 increases the friction between the clamp and the pipe fitting, thereby improving the stability of the clamp fixation.

[0025] The working principle of this embodiment is as follows: when in use, first, unscrew the butterfly screw 7, then pull the first half hoop 1 and the second half hoop 2 to slide on the guide rod 3, so as to adjust the width of the clamp according to the connection range of the pipe fitting, then, embrace the first half hoop 1 and the second half hoop 2 on the pipe fitting, then, merge the first half hoop 1 and the second half hoop 2 together, and insert the steel sheet 9 into the arc groove 10, then insert the butterfly screw 7 into the guide cylinder 6, and then insert it into the threaded cylinder 5 through the guide cover 8, then, tighten the butterfly screw 7 and the threaded cylinder 5 to fix the clamp.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
