DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a wall-penetrating sleeve assembly, comprising two left and right sleeve positioning heads 1, a sleeve telescopic body 2 is fixedly connected between the two sleeve positioning heads 1, a positioning bag assembly 3 is arranged on the outer surface of the two sleeve positioning heads 1, and an adjustment assembly 4 is connected to the far ends of the two sleeve positioning heads 1; due to the arrangement of the sleeve telescopic body 2, the sleeve length can be adapted to different wall thicknesses, i.e., drilling depths, under the cooperation of the two sleeve positioning heads 1, thereby effectively improving the scope of application; and at the same time, greatly reducing the complexity of the production process;

[0023] The positioning bag assembly 3 includes a positioning air bag 31 fixedly sleeved on the outer surface of the casing positioning head 1, the outer surface of the positioning air bag 31 is integrally formed with a number of evenly distributed anti-slip reinforcement ribs 32, an air cavity 33 is provided inside the positioning air bag 31, and a number of evenly distributed through holes 34 are provided between the facing surfaces of the positioning air bag 31 and the casing positioning head 1; due to the setting of the positioning bag assembly 3, the expansion and contraction of the positioning air bag 31 can be controlled by adjusting the assembly 4 with the cooperation of the casing positioning head 1, so that the outer surface of the positioning bag assembly 3 can be closely fitted with the inner wall of the borehole of different diameters; not only can the effect of fixing the casing be achieved, but more importantly, the sealing of both ends of the borehole is greatly improved.

[0024] Among them, the sleeve positioning head 1 includes a positioning connector 11 fixedly connected to the left and right ends of the sleeve telescopic body 2, a through hole 12 is opened in the middle of the positioning connector 11, and a sealing cavity 13 is opened inside the positioning connector 11, and the inner walls of the through hole 12 and the sealing cavity 13 are smooth; due to the setting of the sealing cavity 13, the smooth movement of the adjusting piston ring 41 can be ensured, and then with the cooperation of the through hole 34, the adjusting piston ring 41 can ensure that the air in the sealing cavity 13 can be pressed into the air cavity 33 when it moves, so that the positioning airbag 31 expands, so that its outer surface fits tightly with the inner wall of the drill hole.

[0025] The positioning connector 11 is fixedly sleeved inside the positioning airbag 31 , one end of the through hole 34 is connected to the air cavity 33 , and the other end of the through hole 34 is connected to the sealing cavity 13 .

[0026] Among them, the inner diameter of the through hole 12 is smaller than the minimum inner diameter of the sleeve telescopic body 2, and the inner diameter of the sealing cavity 13 is larger than the inner diameter of the through hole 12; due to the setting of the through hole 12, it can be ensured that the two sides of the wall can be connected to each other after the equipment is fixedly installed, so as to facilitate operations such as pipe threading or wire threading.

[0027] Among them, the adjusting component 4 includes an adjusting piston ring 41 which is movably sleeved inside the sealing chamber 13, and the end of the outer surface of the adjusting piston ring 41 which is away from the sleeve telescopic body 2 is sealingly sleeved inside the sealing chamber 13, and the end of the outer surface of the adjusting piston ring 41 which is close to the sleeve telescopic body 2 is a conical column, and the radial length of the conical column is greater than the diameter of the through hole 34; due to the setting of the conical housing, the situation where the outer surface of the adjusting piston ring 41 blocks the through hole 34 can be avoided, thereby ensuring that the sealing chamber 13 can always be connected with the interior of the air cavity 33 through the through hole 34.

[0028] The outer surface of the adjusting piston ring 41 is connected to a linkage sleeve 42 on one side away from the sleeve telescopic body 2 , and the other end of the linkage sleeve 42 passes through the sealing cavity 13 and extends to the outside of the positioning connector 11 and is fixedly connected to an adjusting ring 43 .

[0029] The inner diameter of the adjusting ring 43 is larger than the inner diameter of the through hole 12 . The outer surface of the linkage sleeve 42 is movably sleeved inside the positioning connector 11 . The inner wall of the linkage sleeve 42 is threadedly sleeved inside the positioning connector 11 .

[0030] The working principle and use process of this utility model:

[0031] First, pull the left and right sleeve positioning heads 1 to move them away from each other, so as to stretch the sleeve telescopic body 2 so that the overall length of the sleeve positioning heads 1 and the sleeve telescopic body 2 increases, and then insert the entire device into the drilled hole in the wall, and then press the sleeve positioning heads 1 at both ends to bring the two closer to each other until the overall length of the device is the same as the wall thickness, that is, the drilling depth. At this time, rotate the two adjusting rings 43 to drive the adjusting piston ring 41 to rotate as a whole through the linkage sleeve 42. Due to the cooperation of the positioning connecting head 11, the linkage sleeve 42 will move left and right while rotating, and then the adjusting piston ring 41 will move along the inside of the sealing cavity 13, so that the air in the sealing cavity 13 can be pressed into the air cavity 33 through the through hole 34, so that the positioning airbag 31 begins to expand as a whole, and under the friction resistance between the anti-slip reinforcement rib 32 and the hole wall, the outer surface of the positioning bag assembly 3 is finally tightly fitted with the hole wall.
