Installation plates are fixedly connected to the outer sides of the left and right sides of the fixing plates. A docking collar is detachably connected to the bottom of the fixing plate. A deviation correction component is arranged inside the docking collar, and the deviation correction component can limit the bellows.
[0007] As a further description of the above technical scheme:
[0008] The deviation correction component includes a limiting groove opened inside the docking collar, and a guiding ring is slidably connected to the inner wall of the limiting groove.
[0009] As a further description of the above technical scheme:
[0010] A locking collar is threadedly connected to the bottom of the docking collar, and a fixing ring is threadedly connected to the top of the docking collar.
[0011] As a further description of the above technical scheme:
[0012] The outer part of the guiding ring is slidably connected to the inside of the locking collar, and the bottom of the fixing ring is in contact with the top of the fixing plate.
[0013] The utility model has the following beneficial effects:
[0014] 1. In the utility model, by designing the fixing plate as a split structure, it is convenient to install through the mounting plate. A blog slot is opened on the inner side of the fixing plate, which can lock the corrugated pipe and increase the sealing performance during use.
[0015] 2. In the utility model, by arranging a docking collar and a guiding ring inside the fixing plate, it can guide the corrugated pipe. At the same time, the locking collar can fix the corrugated pipe to the docking collar and the guiding ring, and the fixing ring is convenient to fix the docking collar to the wall.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a direct-insert bellows wall-penetrating fixator, which includes two fixing plates 1. First, place the fixing plates 1 in appropriate positions for docking and fixing the bellows and connecting with the mounting plate 3. Docking the two fixing plates 1 together, and then fixing them by passing bolts through the mounting plates 3 on both sides. A plurality of bo Wen slots 2 are opened on the inner sides of the two fixing plates 1. Mounting plates 3 are fixedly connected to the outer sides of the left and right sides of the fixing plates 1 to maintain the stability of the entire structure, provide additional support and stability, and facilitate fixing the entire structure in place with bolts. The bottom of the fixing plate 1 is detachably connected with a docking collar 4. Then, pass the bellows through the inside of the docking collar 4 and the fixing plate 1 in sequence. Install the docking collar 4 at the bottom of the fixing plate 1, allowing the bellows to pass through it, and using a deviation correction component to limit and guide the bellows;
[0024] Refer to Figure 3 - Figure 4 , a deviation correction component is arranged inside the docking collar 4. The deviation correction component can limit the bellows to ensure that the bellows maintains the correct position when passing through the docking collar 4 and prevent deviation. The deviation correction component includes a limiting groove 5, which is opened inside the docking collar 4. A guiding ring 6 is slidably connected to the inner wall of the limiting groove 5. The limiting groove 5 and the guiding ring 6 cooperate to provide a stable guiding channel for the bellows. The guiding ring 6 and the limiting groove 5 cooperate to precisely guide the bellows.
[0025] Press the guiding ring 6 against the limiting groove 5 inside the docking collar 4. The bottom of the docking collar 4 is threadedly connected with a locking collar 7. Tighten the locking collar 7 at the bottom of the docking collar 4. Pass the bellows through the middle of the locking collar 7 and the guiding ring 6. The outside of the guiding ring 6 is slidably connected inside the locking collar 7. After tightening, fix the guiding ring 6 in place to ensure the stability of the bellows. The top of the docking collar 4 is threadedly connected with a fixing ring 8. The bottom of the fixing ring 8 is in contact with the top of the fixing plate 1. Pass the top of the docking collar 4 through the wall and tighten the fixing ring 8 to fix the docking collar 4 to the wall for fixing the docking collar 4 to the wall and ensuring the stability of the entire structure.
