[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1

[0028] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a plug shielding pipe for drainage line in live working, the device comprises a pipe body 100, an outer shell 200 and an inner ring 300;

[0029] The outer shell 200 is fixedly connected to the outer side of the tube body 100 , the inner ring 300 is arranged inside the outer shell 200 , and the inner ring 300 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 outside of the tube body 100, a guide block 102 is fixedly connected to the inside of the tube body 100, and a fastening block 103 is arranged inside the guide block 102;

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

[0032] Furthermore, two groups of guide grooves 102a are formed on the inner wall of the guide block 102, and the two groups of guide grooves 102a are symmetrically arranged.

[0033] Furthermore, the top of the fastening block 103 is fixedly connected to a sphere 103a, and the bottom of the fastening block 103 is fixedly connected to a corner block 103b. The sphere 103a is located on the outside of the tube body 100, and the material of the sphere 103a is 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, and the guide block 103c is slidably connected to the inside of the guide groove 102a. A groove 103d is formed on the outer side of the ball 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 defined on the inner wall of the inner ring 300 , and a second inner cavity 303 is defined 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 provided with the anti-slip strip 301 is conical, and the first inner cavity 302 is configured to be conical.

[0037] Preferably, a convex 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 thread groove 201 .

[0038] When in use, first insert the drainage wire through the opening of the tube body 100 into the inside of the tube body 100 until it is in a proper position. Then the operator holds and rotates the inner ring 300, and the inner ring 300 is gradually moved from the inner tube body 100 opening of the outer shell 200 in the cooperation of the threaded plate 303b on the outside of the inner ring 300 and the threaded groove 201 until the threaded plate 303b is separated from the threaded groove 201.

[0039] During the movement of the inner ring 300 toward the opening of the tube body 100, the second inner cavity 303 opened inside 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, driving the corner block 103b at the bottom of the fastening block 103 to move. When the threaded plate 303b is disengaged from the threaded groove 201, the fastening block 103 at this time drives the corner block 103b at the bottom to be embedded into the outside of the rubber sleeve outside the drainage line, thereby fixing the tube body 100 on the outside of the drainage line for shielding the drainage line.

[0040] In summary, after the drainage wire is inserted into the tube body 100 , the inner ring 300 can be rotated to fix the tube body 100 on the outside of the drainage wire to shield the drainage wire.

[0041] Example 2

[0042] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a thread groove 201 and a circular groove 202 are provided on the inner wall of the housing 200 . The diameter of the circular groove 202 is larger than the diameter of the thread groove 201 . A spring 203 is provided inside the circular groove 202 .

[0043] Furthermore, one end of the spring 203 is fixedly connected with a swivel 203 a , and the swivel 203 a 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 drainage line. At the same time, the inner ring 300 will continue to slide under the pulling force of the spring 203. At this time, the sliding inner ring 300 will drive the convex ring 303a in the second inner cavity 303 to squeeze the groove 103d on the outside of the ball 103a. At this time, under the effect of squeezing, the fastening block 103 will be tilted as a whole, thereby changing the angle at which the corner block 103b is embedded in the rubber sleeve on the outside of the drainage line.

[0045] When the guide block 102 is made of insulating rubber, the change of the angle of the corner block 103 b is not affected.

[0046] In summary, after the drainage wire is inserted into the tube body 100, the inner ring 300 can be rotated to embed the corner block 103b into the rubber sleeve outside the drainage wire, so that the drainage wire can be shielded while the tube body 100 can be fixed on the outside of the drainage wire. At the same time, the elasticity of the spring 203 drives the change of the angle of the corner block 103b embedded in the rubber sleeve outside the drainage wire. Even if an accidental touch occurs, the inclined corner block 103b can increase the friction with the rubber sleeve outside the drainage wire to prevent 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 and then rotated to complete the disassembly. This method is not only convenient for overall operation, but also can prevent the device from falling off easily after being set on the outside of the drainage line, thus achieving self-locking.

[0048] Example 3

[0049] Reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, and is based on the second embodiment:

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