DETAILED DESCRIPTION

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, the present invention discloses a universal sealing structure for pipelines, comprising a fixed seat 1, a film cylinder 2, an outer rotating sleeve 3 and a spring 4. The fixed seat 1 is fixed to the wall of a cab, a machine shed, etc., and is pressed on a metal sheet by a buckle. The fixed seat 1 is sleeved with an outer rotating sleeve 3, and the film cylinder 2 is arranged inside the outer rotating sleeve 3. A stop ring 11 is arranged on the outer wall of the inner end of the fixed seat 1, and a spring 4 is sleeved on the fixed seat 1, one end of the spring 4 contacts the stop ring 11, and the other end contacts the end of the outer rotating sleeve 3.

[0025] like Figure 6 As shown, the outer wall of the fixing seat 1 is provided with an elastic protrusion 13, and the inner wall of the outer rotating sleeve 3 is provided with a circumferentially arranged linear groove 32. The elastic protrusion 13 cooperates with the linear groove 32 to limit the rotation of the outer rotating sleeve 3 on the fixing seat 1, and the outer rotating sleeve 3 can be rotated by manual operation. Figure 3 As shown, the film cylinder 2 includes two oppositely arranged first fixing rings 21 and second fixing rings 23 , a film portion 25 is arranged between the first fixing ring 21 and the second fixing ring 23 , and a through hole for the pipeline 5 to pass through is arranged in the middle of the film portion 25 .

[0026] The first fixing ring 21 extends into the fixing seat 1 and is connected to the inner wall of the fixing seat 1. The fixing seat 1 is fixed, so the first fixing ring 21 is a fixed end. The second fixing ring 23 is connected to the inner wall of the end of the outer rotating sleeve 3. When the outer rotating sleeve 3 rotates and slides on the cylindrical outer wall of the fixing seat 1, the second fixing ring 23 rotates and slides with the rotation and sliding of the outer rotating sleeve 3. Therefore, the two fixing rings 23 are movable ends. That is, one end of the film cylinder 2 is fixed with the fixing seat 1, and the other end slides with the rotation and extension of the outer rotating cylinder 3.

[0027] When one end of the film part 25 is fixed and the other end rotates and retracts, the film part 25 in the middle generates a through hole with a varying diameter due to extrusion. When the outer rotating sleeve 3 is in the initial static state, the through hole of the film cylinder 2 is the largest. When the outer rotating sleeve 3 gradually rotates and retracts, the through hole gradually becomes smaller until it is completely closed at a certain position. When the film part 25 is tightened, the through hole is squeezed, so that the through hole and the pipeline 5 are in close contact, thereby achieving sealing of the pipeline 5.

[0028] The working process of the present invention is as follows: the pipeline 5 of the plug can be inserted into the through hole of the film cylinder 2 when it is at its largest, and then the outer rotating sleeve 3 is rotated and contracted toward the inner side of the fixing seat 1 (towards the left in the figure) to adjust the through hole size of the film portion 25 in the film cylinder 2 to the same as the diameter of the wire harness, thereby achieving sealing. Figure 5 As shown, when there is no pipeline passing through the wall, the outer rotating sleeve 3 can also be rotated and retracted until the through hole is closed to achieve complete sealing.

[0029] When the outer rotating sleeve 3 is rotated into position, the outer rotating sleeve 3 cannot rotate relative to each other due to the cooperation and restriction between the elastic protrusion 13 and the linear groove 32. Due to the characteristics of the film cylinder 2, the second fixing ring 23 has a tendency to move inwards, and the spring 4 exerts a thrust on the outer rotating sleeve 3, which can prevent the outer rotating sleeve 3 from sliding inwards, thereby improving the stability of the sealing structure and finally achieving the limiting effect of the entire device.

[0030] The invention has a simple and reliable structure, can realize universal pipeline, has strong feasibility, has great practicality and strong operability. In addition, the invention has good waterproof sealing effect and low cost, and is an ideal wall-passing solution.

[0031] Example 2

[0032] like Figure 1 and Figure 2 As shown, the present invention discloses a universal sealing structure for pipelines, including a fixed seat 1, a film cylinder 2, an outer rotating sleeve 3 and a spring 4. The fixed seat 1 and the outer rotating sleeve 3 are made of plastic. The fixed seat 1 is fixed to the wall of a cab, a shed, etc., and is pressed on a metal sheet by a buckle. The outer rotating sleeve 3 is sleeved on the fixed seat 1, and the film cylinder 2 is arranged inside the outer rotating sleeve 3. A stop ring 11 is arranged on the outer wall of the inner end of the fixed seat 1, and a spring 4 is sleeved on the fixed seat 1, one end of the spring 4 is in contact with the stop ring 11, and the other end is in contact with the end of the outer rotating sleeve 3.

[0033] like Figure 6 As shown, the outer wall of the fixing seat 1 is provided with two elastic protrusions 13, which are symmetrically distributed along the axis of the fixing seat 1. The inner wall of the outer rotating sleeve 3 is provided with circumferentially arranged linear grooves 32, and the elastic protrusions 13 cooperate with the linear grooves 32 to limit the rotation of the outer rotating sleeve 3 on the fixing seat 1, and the outer rotating sleeve 3 can be rotated by manual operation. Figure 3 As shown, the film cylinder 2 includes two first fixing rings 21 and second fixing rings 23 arranged opposite to each other, and the first fixing rings 21 and second fixing rings 23 are made of metal. A film portion 25 is arranged between the first fixing ring 21 and second fixing ring 23, and the film portion 25 is a symmetrical truncated cone structure with large sides and a small middle. A through hole is arranged in the middle of the film portion 25 for the pipeline 5 to pass through.

[0034] The first fixing ring 21 extends into the fixing seat 1 and is connected to the inner wall of the fixing seat 1. Figure 4 As shown, two first connecting protrusions 22 are arranged on the outside of the first fixing ring 21, and the two first connecting protrusions 22 are integrally connected to the first fixing ring 21 and symmetrically distributed along the axis of the film cylinder 2. Two first card slots 12 are provided in the fixing seat 1, which are respectively matched with the first connecting protrusions 22. The fixing seat 1 is fixed, so the first fixing ring 21 is a fixed end. The second fixing ring 23 is connected to the inner wall of the end of the outer rotating sleeve 3, as shown in FIG. Figure 4 As shown, two second connecting protrusions 24 are arranged on the outer side of the second fixing ring 23, and the two second connecting protrusions 24 are integrally connected to the second fixing ring 23 and symmetrically distributed along the axis of the film cylinder 2. Two second clamping grooves 31 respectively matched with the second connecting protrusions 24 are provided in the fixing seat 1. When the outer rotating sleeve 3 rotates and slides on the cylindrical outer wall of the fixing seat 1, the second fixing ring 23 rotates and slides with the rotation and sliding of the outer rotating sleeve 3, so the two fixing rings 23 are movable ends. That is, one end of the film cylinder 2 is fixed with the fixing seat 1, and the other end slides with the rotation and extension of the outer rotating cylinder 3.

[0035] When one end of the film part 25 is fixed and the other end rotates and retracts, the film part 25 in the middle generates a through hole with a varying diameter due to extrusion. When the outer rotating sleeve 3 is in the initial static state, the through hole of the film cylinder 2 is the largest. When the outer rotating sleeve 3 gradually rotates and retracts, the through hole gradually becomes smaller until it is completely closed at a certain position. When the film part 25 is tightened, the through hole is squeezed, so that the through hole and the pipeline 5 are in close contact, thereby achieving sealing of the pipeline 5.
