A type of plug shielding pipe for live-line working

Abstract

This invention relates to the technical field of auxiliary tools for drain lines, and discloses a drain line plug shielding tube for live-line work, comprising a tube body, an outer shell, and an inner ring; the outer shell is fixedly connected to the outside of the tube body, the inner ring is disposed inside the outer shell and sleeved inside the tube body, and one end of the tube body is designed to be open. When the drain line is inserted into the tube body, rotating the inner ring will embed the corner block into the outer rubber sleeve of the drain line, thus shielding the drain line while fixing the tube body to the outside of the drain line. At the same time, under the elasticity of the spring, the angle at which the corner block is embedded into the outer rubber sleeve of the drain line changes. Even if accidental contact occurs, the tilted corner block can increase the friction with the outer rubber sleeve of the drain line, preventing it from falling off.

[0027] Example 1

[0028] Reference Figures 1-4 The first embodiment of the present invention provides a plug shielding tube for live working guide wires. This device includes a tube body 100, an outer shell 200 and an inner ring 300.

[0029] The outer shell 200 is fixedly connected to the outside of the tube body 100, the inner ring 300 is disposed inside the outer shell 200 and is sleeved inside the tube body 100, and one end of the tube body 100 is designed to be open.

[0030] Specifically, a reinforcing rib 101 is fixedly connected to the outer side of the pipe body 100, and a guide block 102 is fixedly connected to the inner side of the pipe body 100. A fastening block 103 is provided inside the guide block 102.

[0031] The reinforcing ribs 101 are set in multiple groups and are located at one end near the end of the tube body 100. The guide block 102 is made of insulating rubber.

[0032] Furthermore, the inner wall of the guide block 102 is provided with two sets of guide grooves 102a, which are symmetrically arranged.

[0033] Furthermore, a sphere 103a is fixedly connected to the top of the fastening block 103, and a corner block 103b is fixedly connected to the bottom of the fastening block 103. The sphere 103a is located on the outside of the tube body 100 and is made of magnetic material. The corner block 103b is located on the inside of the tube body 100, and the cross-section of the corner block 103b is designed to be perpendicular to the center line of the tube body 100.

[0034] Preferably, a guide block 103c is fixedly connected to the outer side of the fastening block 103, the guide block 103c is slidably connected inside the guide groove 102a, and a groove 103d is provided on the outer side of the sphere 103a.

[0035] It should be noted that an anti-slip strip 301 is fixedly connected to the outer side of the inner ring 300, a first inner cavity 302 is opened on the inner wall of the inner ring 300, and a second inner cavity 303 is opened on the inner wall of the inner ring 300.

[0036] Preferably, the inner walls of the first inner cavity 302 and the second inner cavity 303 are made of magnets, the outer wall of the inner ring 300 with the anti-slip strip 301 is conical, and the first inner cavity 302 is also conical.

[0037] Preferably, a protruding ring 303a is fixedly connected to the inner wall of the second inner cavity 303, and a threaded plate 303b is fixedly connected to the outer side of the inner ring 300. The threaded plate 303b is located inside the outer shell 200 and is threadedly connected to the threaded groove 201.

[0038] In use, first insert the drain line into the inside of the tube 100 through the opening until it is in the appropriate position. Then, the operator holds and rotates the inner ring 300. With the cooperation of the threaded plate 303b on the outer side of the inner ring 300 and the threaded groove 201, the inner ring 300 will gradually move from the opening of the tube 100 inside the outer shell 200 until the threaded plate 303b disengages from the threaded groove 201.

[0039] As the inner ring 300 moves toward the opening of the tube body 100, the second inner cavity 303 opened on the inner side of the inner ring 300 and the conical design of the second inner cavity 303 gradually squeeze the ball 103a at the top of the fastening block 103, causing the corner block 103b at the bottom of the fastening block 103 to move. When the threaded plate 303b disengages from the threaded groove 201, the fastening block 103 will then cause the corner block 103b at the bottom to embed into the outside of the rubber sleeve outside the drain line, thereby fixing the tube body 100 to the outside of the drain line for shielding the drain line.

[0040] In summary, by inserting the drainage line into the tube body 100 and rotating the inner ring 300, the tube body 100 can be fixed to the outside of the drainage line for shielding the drainage line.

[0041] Example 2

[0042] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the inner wall of the outer shell 200 is provided with a threaded groove 201 and a circular groove 202. The diameter of the circular groove 202 is larger than the diameter of the threaded groove 201, and a spring 203 is provided inside the circular groove 202.

[0043] Furthermore, one end of the spring 203 is fixedly connected to a rotating ring 203a, which is rotatably connected inside the circular groove 202.

[0044] When the threaded plate 303b is rotated to disengage from the threaded groove 201, the tube body 100 can be fixed on the outside of the drain line. At the same time, under the tension of the spring 203, the inner ring 300 will continue to slide. The sliding inner ring 300 will cause the convex ring 303a in the second inner cavity 303 to squeeze the groove 103d on the outside of the ball 103a. Under the action of squeezing, the fastening block 103 will tilt as a whole, thereby changing the angle at which the corner block 103b is embedded in the rubber sleeve on the outside of the drain line.

[0045] With the guide block 102 made of insulating rubber, the angle of the corner block 103b will not be affected.

[0046] In summary, after the drainage line is inserted into the tube body 100, rotating the inner ring 300 will embed the corner block 103b into the outer rubber sleeve of the drainage line, thus shielding the drainage line and fixing the tube body 100 to the outside of the drainage line. At the same time, under the elasticity of the spring 203, the angle at which the corner block 103b is embedded into the outer rubber sleeve of the drainage line will change. Even if accidental contact occurs, the tilted corner block 103b can increase the friction with the outer rubber sleeve of the drainage line, preventing it from falling off.

[0047] When disassembly is required, the inner ring 300 needs to be pulled to make the threaded plate 303b fit against one end of the threaded groove 201 before rotation can be completed. This method not only makes the overall operation convenient, but also prevents the device from easily falling off after being sleeved on the outside of the drain line, thus achieving self-locking.

[0048] Example 3

[0049] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the second embodiment:

[0050] In summary, by first vertically embedding corner block 103b into the outside of the drainage line rubber sleeve, and then changing the angle of corner block 103b, the vertical embedding effect of corner block 103b is more secure than directly embedding corner block 103b into the outside of the drainage line rubber sleeve by tilting corner block 103b. At the same time, changing the angle of corner block 103b after embedding can further improve the installation stability and avoid the occurrence of unsafe accidents caused by pipe body 100.
