[0020] In this embodiment, the top outer surface and the bottom outer surface of the T-shaped steel sleeve 1 are fixedly connected with sliding bars, and the top inner surface and the bottom inner surface of the positioning sleeve 9 are provided with sliding grooves adapted to the sliding bars. Specifically, when the positioning sleeve 9 is inserted, the sliding grooves are aligned with the sliding bars, and the positioning sleeve 9 is put on the T-shaped steel sleeve 1.

[0021] In this embodiment, the limit block 8 is provided with a first inclined surface 23 facing forward, and the limit block 8 is provided with a second inclined surface 24 facing upward. Specifically, when the positioning sleeve 9 is inserted into the T-shaped steel sleeve 1, the positioning sleeve 9 squeezes the first inclined surface 23, so that the limit block 8 can be received in the receiving groove and the first spring 6 is compressed. When the limit sleeve 15 and the T-shaped steel sleeve 1 are released from the limit, the positioning sleeve 9 is rotated clockwise so that the positioning sleeve 9 squeezes the limit block 8, so that it is received in the receiving groove and the first spring 6 is compressed.

[0022] When the sealing performance of the spigot pipe body 2 needs to be tested, one end of the annular rubber ring of the T-shaped steel sleeve 1 is inserted into the interior of the spigot pipe body 2, and then the positioning sleeve 9 is sleeved on the other end of the T-shaped steel sleeve 1. When the positioning sleeve 9 is inserted and contacts with the limit block 8, as the positioning sleeve 9 is inserted, the positioning sleeve 9 squeezes the limit block 8, causing the first spring 6 to deform. When the limit block 8 contacts with the positioning hole 10, the limit block 8 is inserted into the positioning hole 10 under the elastic force of the first spring 6, and the positioning sleeve 9 is connected to the T-shaped steel sleeve 1, and the extrusion sleeve 12 squeezes the annular pressure plate 4, so that the two annular rubber sealing rings 3 are compressed axially along the T-shaped steel sleeve 1, thereby generating radial expansion, forming two effective seals on the inner wall of the spigot pipe mouth, and then the bell pipe body 2 is tested for sealing performance through the connecting sleeve joint 11, thereby providing convenience for the sealing performance test of the pipeline of this type of vacuum suction system.

[0023] Embodiment 2: Please refer to Figure 1-Figure 8The present invention provides a technical solution: the outer surface of the positioning sleeve 9 is fixedly connected to the limiting sleeve 15, the top outer surface of the limiting sleeve 15 is movably inserted with a first limiting rod 16, the top outer surface of the T-shaped steel sleeve 1 is provided with a first limiting hole 17, the outer surface of the first limiting rod 16 is fixedly sleeved with a disc, a second spring 18 is fixedly connected between the disc and the inner wall of the limiting sleeve 15, and the second spring 18 is sleeved on the outer surface of the first limiting rod 16.

[0024] In this embodiment, the top outer surface of the limit sleeve 15 is fixedly connected to a vertical plate, the top outer surface of the first limit rod 16 is fixedly connected to an adjustment plate 19, a second limit rod 21 is movably inserted into the outer surface of the vertical plate, a pull plate is fixedly connected to the outer surface of the second limit rod 21, a third spring 22 is fixedly connected between the pull plate and the adjustment plate 19, the third spring 22 is sleeved on the outer surface of the second limit rod 21, and two second limit holes 20 are provided on the outer surface of the adjustment plate 19.

[0025] In this embodiment, when the limit block 8 corresponds to the positioning hole 10, the first limit rod 16 corresponds to the first limit hole 17. Specifically, when the limit block 8 is inserted into the positioning hole 10, the first limit rod 16 is inserted into the first limit hole 17, thereby limiting the limit sleeve 15 and the T-shaped steel sleeve 1, thereby limiting the positioning sleeve 9.

[0026] In this embodiment, when the second limiting rod 21 corresponds to the second limiting hole 20 below, the first limiting rod 16 is disengaged from the inside of the first limiting hole 17. Specifically, the second limiting rod 21 is inserted into the second limiting hole 20 to limit the adjustment plate 19. At this time, the first limiting rod 16 is disengaged from the first limiting hole 17 to release the limit between the limiting sleeve 15 and the T-shaped steel sleeve 1.

[0027] In the specific implementation process, after the positioning sleeve 9 is inserted, the first limiting rod 16 is inserted into the first limiting hole 17, and the limiting sleeve 15 and the T-shaped steel sleeve 1 are limited by the first limiting rod 16, so that the positioning sleeve 9 and the T-shaped steel sleeve 1 are limited to avoid relative rotation between the positioning sleeve 9 and the T-shaped steel sleeve 1, thereby increasing the stability of the positioning sleeve 9 outside the annular pressure plate 4. When the positioning sleeve 9 needs to be removed, the second limiting rod 21 is pulled outward to disengage the second limiting rod 21 from the second limiting hole 20, and the third spring 22 is deformed, and then the adjustment plate 19 is pulled upward. When the second limiting rod 21 corresponds to another second limiting hole 20, the second limiting rod 21 is inserted into the second limiting hole 20 to limit the adjustment plate 19. At this time, the first limiting rod 16 is disengaged from the first limiting hole 17, and the positioning sleeve 9 is released from the limit, so that the positioning sleeve 9 can rotate. At this time, the positioning sleeve 9 is rotated so that the inner wall of the positioning hole 10 of the positioning sleeve 9 squeezes the limiting block 8, so that the first spring 6 is deformed, and the limiting block 8 is disengaged from the inside of the positioning hole 10, thereby releasing the limit of the T-shaped steel sleeve 1 and the positioning sleeve 9, so that the positioning sleeve 9 is removed from the surface of the T-shaped steel sleeve 1.

[0028] Embodiment 3: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: an extrusion sleeve 12 is movably sleeved on the outer surface of the positioning sleeve 9, and screw holes 13 are provided on the outer surfaces of the extrusion sleeve 12 and the positioning sleeve 9. There are several screw holes 13 on the outer surface of the positioning sleeve 9 and they are arranged in a linear array. The corresponding screw holes 13 of the extrusion sleeve 12 and the positioning sleeve 9 are threadedly connected with an adjusting hand wheel 14.

[0029] During the specific implementation process, the overall length of the positioning sleeve 9 and the extrusion sleeve 12 can be adjusted according to the required force of extruding the annular pressure plate 4. At this time, the adjusting hand wheel 14 is unscrewed, and the position of the extrusion sleeve 12 in the positioning sleeve 9 is adjusted so that the screw holes 13 between the extrusion sleeve 12 and the positioning sleeve 9 correspond to each other. The adjusting hand wheel 14 is screwed into the corresponding screw holes 13 to limit the extrusion sleeve 12 and the positioning sleeve 9, so that the overall length of the positioning sleeve 9 and the extrusion sleeve 12 can be adjusted, and then the extrusion force on the annular pressure plate 4 and the annular rubber sealing ring 3 can be adjusted.

[0030] Working principle: When the present invention is in use, when it is necessary to perform a sealing test on the bell-and-spigot pipe body 2, one end of the annular rubber ring of the T-shaped steel sleeve 1 is inserted into the interior of the bell-and-spigot pipe body 2, and then the positioning sleeve 9 is sleeved on the other end of the T-shaped steel sleeve 1. When the positioning sleeve 9 is inserted and contacts with the limit block 8, as the positioning sleeve 9 is inserted, the positioning sleeve 9 squeezes the limit block 8, causing the first spring 6 to deform. When the limit block 8 contacts with the positioning hole 10, the limit block 8 is inserted into the positioning hole 10 under the elastic force of the first spring 6, and the positioning sleeve 9 is connected to the T-shaped steel sleeve 1, and the extrusion sleeve 12 squeezes the annular pressure plate 4, so that the two annular rubber sealing rings 3 are compressed axially along the T-shaped steel sleeve 1, and then radial expansion is generated, forming two effective seals on the inner wall of the bell-and-spigot pipe mouth, and then the bell-and-spigot pipe body 2 is tested for sealing through the connecting sleeve joint 11, thereby providing convenience for the sealing test of the pipeline of this type of vacuum suction system.

[0031] After the positioning sleeve 9 is inserted, the first limiting rod 16 is inserted into the first limiting hole 17, and the limiting sleeve 15 and the T-shaped steel sleeve 1 are limited by the first limiting rod 16, so that the positioning sleeve 9 and the T-shaped steel sleeve 1 are limited to avoid relative rotation between the positioning sleeve 9 and the T-shaped steel sleeve 1, thereby increasing the stability of the positioning sleeve 9 outside the annular pressure plate 4. When the positioning sleeve 9 needs to be removed, the second limiting rod 21 is pulled outward to disengage the second limiting rod 21 from the second limiting hole 20, and the third spring 22 is deformed, and then the adjusting plate 19 is pulled upward. When the second limiting When the rod 21 corresponds to another second limiting hole 20, the second limiting rod 21 is inserted into the second limiting hole 20 to limit the adjustment plate 19. At this time, the first limiting rod 16 is disengaged from the first limiting hole 17, and the positioning sleeve 9 is released from the limit, so that the positioning sleeve 9 can rotate. At this time, the positioning sleeve 9 is rotated so that the inner wall of the positioning hole 10 of the positioning sleeve 9 squeezes the limiting block 8, so that the first spring 6 is deformed, and the limiting block 8 is disengaged from the inside of the positioning hole 10, thereby releasing the limit of the T-shaped steel sleeve 1 and the positioning sleeve 9, so that the positioning sleeve 9 is removed from the surface of the T-shaped steel sleeve 1.

[0032] According to the required force of extruding the annular pressure plate 4, the overall length of the positioning sleeve 9 and the extrusion sleeve 12 can be adjusted. At this time, the adjusting hand wheel 14 is unscrewed, and the position of the extrusion sleeve 12 in the positioning sleeve 9 is adjusted so that the screw holes 13 between the extrusion sleeve 12 and the positioning sleeve 9 correspond to each other. The adjusting hand wheel 14 is screwed into the corresponding screw holes 13 to limit the extrusion sleeve 12 and the positioning sleeve 9, so that the overall length of the positioning sleeve 9 and the extrusion sleeve 12 can be adjusted, and then the extrusion force on the annular pressure plate 4 and the annular rubber sealing ring 3 can be adjusted.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
