Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, specifically to a mechanism for installing heat shrink tubing on power transmission lines. Background Technology

[0002] Heat shrink tubing, also known as heat shrink sleeve, is a special type of plastic tubing that shrinks in diameter when exposed to heat, tightly wrapping around the surface of cables, connectors, or other objects. The main function of heat shrink tubing is to provide insulation protection for wires, cables, and other connectors, preventing short circuits, and also providing waterproofing, moisture protection, and corrosion resistance.

[0003] When existing heat shrink tubing is applied to the outer surface of power transmission lines, the wires need to be manually passed through the opening of the heat shrink tubing. However, when the diameter of the wire is large, it is difficult to quickly pass the wire through the heat shrink tubing. Therefore, the installation of the wires is not only difficult but also inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a heat shrink tubing installation mechanism for power transmission lines. By using this device, the problem of low installation efficiency of existing heat shrink tubing installation mechanisms for power transmission lines can be solved.

An annular plate is fixedly installed on one end of the spring. The inner side of the annular plate is in contact with the outer surface of the wire.

[0007] Furthermore, the groove block is configured as a cone shape, and the inner wall of the heat shrink tubing is in contact with the outer surface of the groove block.

[0008] Furthermore, the outer surface of the groove block is provided with a wear-resistant layer, which is a component made of polytetrafluoroethylene coating.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] Please see Figures 1-4 The auxiliary component 6 includes a mounting plate 61 disposed on the upper surface of the base plate 1, and an auxiliary plate 62 disposed on one side of the mounting plate 61. The other side of the mounting plate 61 is fixedly connected to one side of the arc-shaped base 2. A groove 63 is provided on one side of the auxiliary plate 62. An electric push rod A64 is fixedly installed on the inner wall of the groove 63. A moving block 65 is fixedly installed on the telescopic end of the electric push rod A64. A round rod 66 is provided on one side of the moving block 65. A groove block 67 is fixedly installed on one end of the round rod 66. A spring 68 is fixedly installed on the inner wall of the groove block 67. An annular plate 69 is fixedly installed on one end of the spring 68. The inner side of the annular plate 69 is in contact with the outer surface of the wire 4, thereby improving the accuracy and efficiency of the installation.

[0026] The groove 67 is set in a conical shape, and the inner wall of the heat shrink tubing 3 contacts the outer surface of the groove 67. The conical design makes it easier for the groove 67 to be inserted into the heat shrink tubing 3.

[0027] The outer surface of the groove block 67 is provided with a wear-resistant layer, which is a component made of polytetrafluoroethylene coating, making the groove block 67 more wear-resistant.

[0028] A circular hole 611 is provided on one side of the mounting plate 61, and a circular rod 66 passes through the inside of the circular hole 611 to facilitate adjustment of the position of the circular rod 66.

[0029] A mounting base 7 is provided on one side of the movable block 65. A clamping plate 71 is threadedly connected to the upper surface of the mounting base 7. One end of the round rod 66 is fitted into the interior of the mounting base 7, which facilitates the disassembly and installation of the round rod 66.

[0030] The clamping assembly 5 includes an electric push rod B51 fixedly installed on the upper surface of the base plate 1, and a fixing box 52 fixedly installed on the telescopic end of the electric push rod B51. An arc-shaped pressure block 53 is fixedly installed at the bottom of the fixing box 52. The outer surface of the arc-shaped pressure block 53 contacts the inner wall of the arc-shaped base 2 to prevent the heat shrink tubing 3 from shifting and to not affect the entry of the wire 4.

[0031] A miniature fan 8 is provided on the upper surface of the fixing box 52, and a heating plate 81 is provided on the inner wall of the fixing box 52.

Then, install the round rod 66 back into the mounting base 7 and fix it. Then, insert one end of the wire 4 into the groove block 67. At the same time, the spring 68 and the annular plate 69 inside the groove block 67 clamp the wire 4. Then, by the contraction of the electric push rod B51, the fixing box 52 and the arc-shaped pressure block 53 are pressed down together, thereby fixing the heat shrink tubing 3. Then, by the extension of the electric push rod A64, the movement of the moving block 65 drives the round rod 66 and the wire 4 it holds to pass through the heat shrink tubing 3, thereby improving the tubing effect. Finally, the air heated by the heating plate 81 is passed through the ventilation hole 82 by the micro fan 8, thereby heating the heat shrink tubing 3, making it tightly wrap the wire 4, thereby improving the heat shrinking efficiency.
