Description

Technical Field

[0001] This utility model relates to the technical field of positioning clamping sleeves for copper pipe fittings, and in particular to a positioning clamping sleeve for copper pipe fittings. Background Technology

[0002] The connection between existing copper pipe fittings and plastic pipes (PEX pipe, PR pipe, PVC pipe, PE pipe, etc.) is usually achieved by using a straight-through clamping sleeve and a special crimping tool to press the sleeve against the outside.

[0003] However, the existing technology still has shortcomings. Because the straight-through clamping sleeve in the existing technology does not have a positioning device, it is easy for it to move around in the plastic tube. When clamping, it cannot be guaranteed that the clamping sleeve is clamped on the rib of the copper tube fitting, thus resulting in relatively low stability.

[0004] Therefore, we propose a positioning clamping sleeve for copper pipe fittings to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to provide a positioning clamping sleeve for copper pipe fittings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning clamping sleeve for copper pipe fittings includes a main housing; an auxiliary ring is fixedly connected to the outer circular surface of the main housing; a first thread is provided on the upper side of the outer circular surface of the main housing; a second thread is provided on the lower side of the outer circular surface of the main housing; a limiting ring is fixedly connected to the inner surface of the main housing; a pressing block is fixedly connected to the outer surface of the limiting ring; a first pressing ring is rotatably mounted on the upper side of the outer circular surface of the main housing; a first thread groove is provided on the inner surface of the first pressing ring; a second pressing ring is rotatably mounted on the lower side of the outer circular surface of the main housing; a second thread groove is provided on the inner surface of the second pressing ring; and a clamping device is fixedly connected to the outer surface of the main housing.

[0008] Preferably, the clamping device includes a clamping block fixed to the outer surface of the main housing; a rubber block is fixed to one side of the outer surface of the clamping block.

[0009] Preferably, one outer surface of the clamping block is an arc-shaped surface; one side of the clamping block is inclined outward.

[0010] Preferably, the No. 1 thread and the No. 1 thread groove are mutually engaged; the No. 2 thread and the No. 2 thread groove are mutually engaged.

[0011] Preferably, the outer surface of the auxiliary ring is provided with a first anti-slip texture; the outer surface of the first extrusion ring is provided with a second anti-slip texture; and the outer surface of the second extrusion ring is provided with a third anti-slip texture.

[0012] In this utility model, a positioning clamping sleeve for copper pipe fittings is provided. Through the arrangement of a main shell, a first thread, a second thread, a limiting ring, an auxiliary ring, a first anti-slip groove, a first compression ring, a second anti-slip groove, a first thread groove, a second compression ring, a third anti-slip groove, a second thread groove, a clamp, a clamping block, and a rubber block, the main shell is fitted onto the outer surface of the water pipe. Rotating the first compression ring causes it to move, which in turn compresses the clamping block. The first compression ring, through the clamping block, compresses the surface of the water pipe, completing the installation of the main shell. Then, the copper pipe fitting is pushed into the main shell. Rotating the second compression ring causes it to move, which in turn compresses the clamping block. The second compression ring, through the clamping block, compresses the surface of the copper pipe fitting, completing the positioning and clamping. This enables rapid installation and positioning of the copper pipe fitting, improving stability.

[0013] In this utility model, a positioning clamping sleeve for copper pipe fittings can compress the water pipe and copper pipe fittings by setting the compression block, thereby further fixing the water pipe and copper pipe fittings and improving stability.

[0014] This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description

[0021] Furthermore, the clamping device 5 includes a clamping block 51 fixed to the outer surface of the main housing 1; a rubber block 52 is fixed to one side of the outer surface of the clamping block 51.

[0022] Furthermore, one side of the outer surface of the clamping block 51 is an arc-shaped surface; one side of the clamping block 51 is inclined outward.

[0023] Furthermore, thread 11 and thread groove 32 are mutually engaged; thread 12 and thread groove 42 are mutually engaged.

[0024] Furthermore, the outer surface of the auxiliary ring 2 is provided with a first anti-slip texture 21; the outer surface of the first extrusion ring 3 is provided with a second anti-slip texture 31; and the outer surface of the second extrusion ring 4 is provided with a third anti-slip texture 41.

[0025] In this invention, during use, the main housing 1 is fitted onto the outer surface of the water pipe. Rotating the first compression ring 3 causes it to move, which in turn compresses the clamping block 51. This compression of the water pipe surface by the first compression ring 3 and the clamping block 51 completes the installation of the main housing 1. Then, the copper pipe fitting is pushed into the main housing 1. Next, rotating the second compression ring 4 causes it to move, which in turn compresses the clamping block 51. This compression of the copper pipe fitting surface by the clamping block 51 completes the positioning and tightening, enabling rapid installation and positioning of the copper pipe fitting, thus improving stability. The compression block 14 further compresses the water pipe and copper pipe fitting, further enhancing stability.
