[0023] The principle and structure of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0024] Referring to Figure 1-6 , a building pipe wall-piercing connection device includes a pipe body 1. A support sleeve 2 is sleeved on the surface of the pipe body 1. A chute 7 is provided on the side surface of the support sleeve 2. A slider 9 is slidably connected in the chute 7. A limiting block 5 is fixedly connected to the right side surface of the slider 9. A threaded sleeve 3 is threadedly connected to the surface of the support sleeve 2. A limiting groove 6 is provided in the inner ring of the threaded sleeve 3. The side surface of the limiting block 5 is slidably connected and fitted with the inner wall of the limiting groove 6. A limiting hole 8 is provided on the side surface of the support sleeve 2. A support plate 10 is rotatably connected in the limiting hole 8. Two support rods 12 are rotatably connected to the side surface of the slider 9. One ends of the two support rods 12 are rotatably connected to the side surface of the support plate 10. A support block 11 is rotatably connected between the two support rods 12. A pressing plate 4 is fixedly connected to the side surface of the support block 11.

[0025] By providing the pressing plate 4, the device can be limited when the pressing plate 4 abuts against the wall hole.

[0026] Furthermore, the shape of the side surface of the slider 9 matches the shape of the inner wall of the chute 7, and the shape of the side surface of the limiting block 5 matches the shape of the inner wall of the limiting groove 6.

[0027] By providing the limiting groove 6, the threaded sleeve 3 can drive the limiting block 5 to move through the limiting groove 6.

[0028] Furthermore, the inner diameter of the threaded sleeve 3 matches the outer diameter of the support sleeve 2, and the inner diameter of the support sleeve 2 matches the outer diameter of the pipe body 1.

[0029] Furthermore, the side surface of the pressing plate 4 is set to be arc-shaped, and the number of the pressing plates 4 is set to be two.

[0030] By setting the abutting plate 4 to be arc-shaped, the arc-shaped abutting plate 4 can better fit the inner wall of the wall hole.

[0031] Furthermore, the number of the sliders 9 matches the number of the limiting blocks 5, and the number of the support plates 10 matches the number of the sliders 9.
