Description

Technical Field

[0001] The utility model relates to the technical field of fire protection pipe laying, in particular to a pipe laying cavity repairing device for fire protection engineering. Background Art

[0002] During the installation of fire protection piping, holes are created in the walls to allow the pipes to pass through. To ensure building integrity, fire and moisture resistance, and prevent pests such as rats, insects, and small animals from entering through these holes, these holes need to be sealed and repaired after the pipes are installed. This is typically done using a dedicated sealing device, one part of which is attached to the pipe and the other part is attached to the wall.

[0003] The existing sealing device has a part that is attached to the wall, and sand and gravel will fall from the upper end, which will be subjected to downward pressure. After long-term use, it will deform, causing gaps in the sealing part. Therefore, it is necessary to provide a cavity repair device for laying pipes for fire protection engineering to solve the above problem. Utility Model Content

[0007] A blocking assembly, comprising a curved splint and a sealing plate. The curved splint consists of two pieces, and the sealing plate is integrally formed and connected to the outside of one end of the curved splint.

[0008] A stabilizing assembly includes a square through hole, a connecting shaft, a torsion spring, a support plate and an anti-slip pad. The square through hole is opened at one end of the sealing plate, the connecting shaft is fixed in the middle of the square through hole, the torsion spring is sleeved on the connecting shaft, one end of the support plate is sleeved on the connecting shaft, and the side of the anti-slip pad is fixed to the end of the side of the support plate away from the connecting shaft.

[0009] Furthermore, the stabilization assembly also includes a protective cover, a fixed plate and an adjusting screw. The side of the protective cover is hinged on the sealing plate and is located on the side of the square through hole. One end of the fixed plate is fixed on the sealing plate and is located on the other side of the square through hole. The adjusting screw is screwed to the other end of the fixed plate.

[0010] Furthermore, the protective cover is connected to the square through hole, and the adjusting screw is movably connected to the protective cover.

[0011] Furthermore, the blocking assembly further comprises a fixing block and a bolt. The fixing block is integrally formed and connected to both ends of the arc-shaped clamping plate, and the bolt is inserted into the middle of the fixing block.

[0012] Furthermore, it also includes an adjustment component, which includes a groove and a mounting hole. The groove is opened at the outer end of the sealing plate, and the mounting hole is opened on the sealing plate and communicated with the groove.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model provides a stabilizing component. A curved splint is held in hand to fit the outer wall of the pipe. The support plate is moved by fingers to rotate around the connecting axis and the curved splint is pushed upward to extend the support plate into the cavity. The sealing plate fits the wall and the support plate is released. Under the action of the torsion spring, the anti-slip pad on the support plate is pressed tightly against the inner wall of the cavity. Another curved splint is placed in, and finally a bolt is passed through the through hole on the fixing block and tightened. The protective cover is then rotated to cover the square through hole and the adjusting screw on the fixing plate is turned until one end of the adjusting screw is located above the protective cover. This arrangement firmly presses the support plate and the anti-slip pad against the inner wall of the cavity through the torsion spring, thereby improving the stability of the connection between the sealing plate and the cavity.

[0016] 2. The utility model has an adjustment component. When a hole is opened, the size of the hole is different. If the hole is large, the splicing plate can be held and the plug can be inserted into the groove. The screw can be tightened from the mounting hole to fix the plug in the groove. This setting can improve the applicability of the blocking component. BRIEF DESCRIPTION OF THE DRAWINGS
