Description

Technical Field

[0001] The utility model relates to the technical field of watertight plugging of cable pipe holes, in particular to a self-expanding watertight plugging device for cable pipe holes. Background Art

[0002] Cable pipe hole watertight plugging devices often use flanges of various types to fix and seal the two ends of the cable after passing through a box or a wall. Since the size of the flange is fixed, flanges of various sizes and types are required to adapt to the passing and fixing of holes of various sizes of walls or boxes, which is cumbersome and costly to operate.

[0003] The existing cable pipe hole watertight plugging technology mostly uses flanges for sealing and plugging. The flanges cannot adapt to a variety of hole sizes and cannot be completely sealed. For example, a cable pipe sealing device disclosed in publication number CN208508487U includes a sealing belt, one side of the sealing belt is provided with uniform perforations from top to bottom, the other side of the sealing belt is provided with a threading belt corresponding to the perforation position, the threading belt is provided with anti-falling protrusions, and the sealing belt is provided with a number of U-shaped clips for clamping the sealing belt interface at the closed part, and an elastic sealing layer is provided on the inner side of the sealing belt. This scheme uses a cable pipe sealing device for sealing, which has waterproof, rat-proof, anti-theft and other effects, and can avoid adverse effects such as water accumulation and mud. However, this scheme cannot completely fix the cable pipe, is easy to shake, and cannot adapt to the use of cable pipes of various sizes.

[0004] Therefore, it is necessary to invent a self-expanding cable pipe hole watertight plugging device to solve the above problems. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 The self-expanding cable pipe hole watertight plugging device shown comprises a cable pipe body 1, a No. 1 sleeve 3, a No. 2 sleeve 4 and a No. 3 sleeve 5. The cable pipe body 1 can penetrate into a wall or a box body 2, and the No. 1 sleeve 3, the No. 2 sleeve 4 and the No. 3 sleeve 5 are sequentially sleeved on the side end of the cable pipe body 1 extending into the wall or the box body 2. The No. 2 sleeve 4 and the No. 3 sleeve 5 clamp the wall or the box body 2 through an expansion mechanism.

[0024] The cable tube body 1 and the wall or box body 2 are fixed in position by respectively tightening and inserting the two ends of the second sleeve 4 into the first sleeve 3 and the third sleeve 5, so as to prevent shaking and wear.

[0025] The expansion mechanism includes an elastic sleeve 1 401, an elastic sleeve 2 402 and a self-expanding foam capsule 403. The elastic sleeve 1 401 and the elastic sleeve 2 402 are respectively fixedly connected to the two ends of the No. 2 sleeve 4. A self-expanding foam capsule 403 is arranged in each gap between the elastic sleeves 402. The expansion mechanism also includes an isolation layer 404, a stripping film 405 and a rubber gasket 406. The isolation layer 404 is arranged on the inner side of the elastic sleeve 2 402. The ends of the isolation layer 404 and the stripping film 405 can contact each other. The other end of the stripping film 405 is connected to the rubber gasket 406.

[0026] The self-expansion mechanism not only fixes the position between the fixed cable tube body 1 and the wall or box body 2, but also completely seals the gap between them, improves the sealing performance, and is moisture-proof and waterproof and tightly connected.

[0027] A plurality of pins 501 are evenly fixedly connected to the No. 3 sleeve 5, and a plurality of spikes 502 are fixedly provided on the pins 501. The plurality of spikes 502 are all inclined, and the angle opening directions are in the same direction. The elastic sleeve 1 401 and the elastic sleeve 2 402 are initially in a contracted state, and the length of the elastic sleeve 1 401 is twice the length of the elastic sleeve 2 402. The gap width between the elastic sleeve 2 402 is greater than the gap width of the elastic sleeve 1 401. The self-expanding foam capsules 403 are fixed in each gap between the elastic sleeve 2 402, and the surface thereof is easily punctured. The number and position of the plurality of self-expanding foam capsules 403 correspond to the pins 501.

[0028] The self-expanding foam capsule 403 is punctured by the contact between the insertion needle 501 and the spike portion 502 to expand the foam material, fill the gap between the No. 1 sleeve 3 and the No. 2 sleeve 4, and fill the gap between the cable tube body 1 and the wall or box body 2. After standing, the edges of the excess foam material on the surface can be cleaned, and the surface of the cable tube body 1 can be isolated by the isolation layer 404 and the stripping film 405 to prevent contamination.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the utility model, first sleeve No. 1 sleeve 3 is sleeved onto the cable tube body 1, then sleeve No. 2 sleeve 4 is sleeved onto the cable tube body 1, then the end of the cable tube body 1 is passed through the hole of the wall or box body 2, then sleeve No. 3 sleeve 5 is sleeved onto the end passing through the wall or box body 2 and connected to No. 2 sleeve 4, and the No. 1 sleeve 3 and the No. 2 sleeve 4 are tightened;

[0031] Refer to the instruction manual Figure 3-5 When using the utility model, the first sleeve 3 is screwed onto the second sleeve 4 to preliminarily fix the position of the cable tube body 1 and the wall or box body 2. When the third sleeve 5 is inserted into the second sleeve 4, the needle 501 and the spike 502 will puncture the self-expanding foam capsule 403, and the foam will expand, forming a sealed and fixed state between the second sleeve 4 and the third sleeve 5. After standing for a period of time, the positions of the second sleeve 4 and the third sleeve 5 will be completely fixed, and the cable tube body 1 and the wall or box body 2 will be completely fixed;

[0032] Since the foam glue will fill the gap of the elastic sleeve 2 402 and the gap between the second sleeve 4 and the third sleeve 5, it can avoid contamination to the surface of the wall or the box body 2. The contact between the isolation layer 404 and the peeling film 405 is used to isolate the foam glue material from the surface of the cable tube body 1 without affecting the pressure of the foaming and squeezing.
