Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sleeves, in particular to a heat shrinkable sleeve with high sealing performance. Background Art
[0002] Heat shrink tubing is a special polyolefin heat shrink tubing. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance, and the inner layer has the advantages of low melting point, waterproof sealing, and high adhesion. The expansion sleeve sometimes needs to be docked. The current heat shrink tubing is prone to gaps after docking, which affects the sealing of the tubing. Utility Model Content
[0003] The utility model aims to provide a heat shrinkable sleeve with high sealing performance, which solves the problem that the existing heat shrinkable sleeves are prone to produce gaps after being butted, thereby affecting the sealing performance of the sleeves.
[0004] Technical Solution
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a highly sealing heat shrinkable sleeve, comprising a first tube body, the right end of the first tube body contacts the second tube body, the surfaces of the first tube body and the second tube body are respectively fixedly connected with a first docking ring and a second docking ring, the first docking ring and the second docking ring overlap each other, the upper surfaces of the first docking ring and the second docking ring are both provided with a fixing groove, the interiors of the two fixing grooves are both clamped with a fixing block, a top plate is fixedly connected between the two fixing blocks, the upper surface of the first tube body is fixedly connected with a fixing bar, the right side of the fixing bar is provided with a spring groove, the inner wall of the spring groove is fixedly connected with a spring, the right end of the spring is fixedly connected with a fixing rod, and the right end of the fixing rod is fixedly connected with a clamp.
[0006] Furthermore, there are two clamping members, which are respectively located at the upper left corner and the upper right corner of the top plate for clamping.
[0007] Furthermore, the inner wall of the clamp is overlapped with the side surfaces of the first docking ring and the second docking ring.
[0008] The utility model provides a heat shrink tubing with high sealing performance. It has the following beneficial effects:
[0009] The highly sealed heat shrinkable sleeve can seal and fasten the joints of the two sleeves to each other through the mutual cooperation between the first docking ring, the second docking ring, the top plate, the fixing groove, the fixing block, the clamp, the fixing rod, the spring groove, the fixing strip and the spring, thereby solving the problem that the existing heat shrinkable sleeves are prone to gaps after docking, thereby affecting the sealing of the sleeves. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 For this utility model Figure 1 A magnified view of the local structure at point A.
[0012] Among them, 1 is a first tube body, 2 is a second tube body, 3 is a first docking ring, 4 is a second docking ring, 5 is a top plate, 6 is a fixing groove, 7 is a fixing block, 8 is a clamp, 9 is a fixing rod, 10 is a spring groove, 11 is a fixing strip, and 12 is a spring. DETAILED DESCRIPTION
[0013] like Figure 1-2 As shown, the embodiment of the utility model provides a heat shrink sleeve with high sealing performance, including a first tube body 1, the right end of the first tube body 1 contacts the second tube body 2, the surfaces of the first tube body 1 and the second tube body 2 are respectively fixedly connected with a first docking ring 3 and a second docking ring 4, the first docking ring 3 and the second docking ring 4 overlap each other, the upper surfaces of the first docking ring 3 and the second docking ring 4 are both provided with a fixing groove 6, the interiors of the two fixing grooves 6 are clamped with a fixing block 7, a top plate 5 is fixedly connected between the two fixing blocks 7, the upper surface of the first tube body 1 is fixedly connected with a fixing bar 11, the right side of the fixing bar 11 is provided with a spring groove 10, the inner wall of the spring groove 10 is fixedly connected with a spring 12, the right end of the spring 12 is fixedly connected with a fixing rod 9, the right end of the fixing rod 9 is fixedly connected with a clamp 8, the number of the clamps 8 is two, the two clamps 8 are respectively located at the upper left corner and the upper right corner of the top plate 5 for clamping, and the inner wall of the clamp 8 overlaps the side of the first docking ring 3 and the second docking ring 4.
[0014] Working principle: Pull the two clamps 8 in opposite directions. After the first tube body 1 and the second tube body 2 are connected, place the top plate 5 downward first so that the fixing block 7 is inserted into the fixing groove 6 to fix the first tube body 1 and the second tube body 2. Then release the two clamps 8. At this time, the two springs 12 will push the fixing rod 9 to reset, so that the two clamps 8 will clamp the top plate 5 to limit the position.
