Description

Technical Field

[0001] The utility model relates to the technical field of cable installation auxiliary equipment, in particular to a casing with good safety. Background Art

[0002] When cables are introduced into underground or outdoor structures, they must pass through the walls, components or plates inside the structures. The passed parts often become the weakest parts of the entire structure's waterproofing. Therefore, when cables are introduced into underground or outdoor structures, they are generally installed in pre-buried steel pipes, which are then filled and sealed with sealant to prevent groundwater or outdoor water from entering the room through the gap between the cable and the casing.

[0003] After searching, Chinese patent announcement number: CN208423703U discloses a waterproof casing, including making it easier to fill sealant into the empty space of the casing body, so that the sealant can fully play its sealing role, and prevent groundwater from flowing through the gap in the casing body. The first waterproof fastening device and the second waterproof fastening device prevent groundwater from flowing through the gap between the outer wall of the casing body and the wall.

[0004] However, during actual use of the above-mentioned sleeve, when using sealant to fill the gap between the cable and the sleeve, if the cable moves after the sealant is completely cured, cracks may appear at the joints between the sealant and the cable, which may cause external moisture to penetrate into the room through the gaps, causing potential problems. At the same time, if resealing is required, it will become quite difficult. Therefore, a sleeve with good safety is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a sleeve with good safety, aiming to improve the problem in the prior art that the gap between the sleeve and the cable is sealed by sealant, and gaps will appear after long-term use.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a sleeve with good safety, including a cable, a sleeve body is sleeved on the outside of the cable, a fixing cylinder is fixedly connected to the front side of the sleeve body, a threaded groove is provided on the inner wall surface of the fixing cylinder, an annular threaded plate is threadedly connected to the interior of the fixing cylinder through the threaded groove, and a rubber ring is provided inside the fixing cylinder.

[0007] As a further description of the above technical solution:

[0008] The rear inner wall surface of the fixing cylinder is fixedly connected to a limiting ring, and the back surface of the annular threaded plate is fixedly connected to a limiting rod.

[0009] As a further description of the above technical solution:

[0010] A handle is fixedly connected to the front side surface of the annular threaded plate, and an anti-slip groove is provided on the outer wall surface of the handle.

[0011] As a further description of the above technical solution:

[0012] A plurality of cavities are provided inside the rubber ring, and the cavities are arranged in a honeycomb structure inside the rubber ring.

[0013] As a further description of the above technical solution:

[0014] The center of the back side of the fixing cylinder is provided with a hollow structure, and the fixing cylinder is sleeved on the outside of the cable.

[0015] As a further description of the above technical solution:

[0016] A gap is left between the inner wall of the annular threaded plate and the outer wall surface of the cable.

[0017] As a further description of the above technical solution:

[0018] The rubber ring is sleeved on the outside of the cable.

[0019] As a further description of the above technical solution:

[0020] The rear end of the limiting rod is inserted into the gap between the limiting ring and the inner wall of the fixing cylinder.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: a casing with good safety, including a cable 1, a casing body 2 is provided on the outside of the cable 1, the casing body 2 can be pre-buried inside the wall, and the cable 1 is introduced into the room through the casing body 2. The casing body 2 protects the outer side of the part of the cable 1 located inside the wall after passing through the wall. The front side of the casing body 2 is fixedly connected to a fixing cylinder 3, and the center of the back side of the fixing cylinder 3 is hollow, which can prevent the fixing cylinder 3 from hindering the cable 1 from passing through the casing body 2. The fixing cylinder 3 is sleeved on the outside of the cable 1 and is located on the outside of the wall.

[0033] Reference Figure 1-Figure 3The inner wall surface of the fixing cylinder 3 is provided with a thread groove 4, and the interior of the fixing cylinder 3 is threadedly connected to an annular threaded plate 5 through the thread groove 4. When the annular threaded plate 5 rotates, it will perform linear motion in the front and rear directions relative to the fixing cylinder 3 under the limit of the thread groove 4. A gap is left between the inner wall of the annular threaded plate 5 and the outer wall surface of the cable 1, which can avoid contact friction between the annular threaded plate 5 and the cable 1, thereby reducing the friction resistance endured by the annular threaded plate 5 when rotating. A handle 6 is fixedly connected to the front side surface of the annular threaded plate 5, and the staff can drive the annular threaded plate 5 to rotate quickly through the handle 6, which is convenient for the staff to use the annular threaded plate 5. The outer wall surface of the handle 6 is provided with an anti-slip groove, which can increase the friction between the handle 6 and the user's palm to avoid slipping.

[0034] A rubber ring 7 is provided inside the fixing tube 3, and the rubber ring 7 is sleeved on the outside of the cable 1. When the annular threaded plate 5 moves toward the rear side, the rubber ring 7 will be squeezed, causing the rubber ring 7 to produce elastic deformation, so that the rubber ring 7 can further seal the gap between the cable 1 and the sleeve body 2. At the same time, since the rubber ring 7 can automatically restore its deformation after being squeezed, the situation where the cable 1 shakes and causes gaps on the outside can be avoided. A number of cavities 8 are opened inside the rubber ring 7, and the cavity 8 is arranged in a honeycomb structure inside the rubber ring 7. By providing the cavity 8, a greater degree of deformation of the rubber ring 7 can be achieved, and at the same time, the internal stress of the rubber ring 7 can be reduced, so that the annular threaded plate 5 can quickly squeeze the rubber ring 7, which is convenient for the staff to operate and more labor-saving.

[0035] Reference Figure 4-Figure 5 The rear inner wall surface of the fixed cylinder 3 is fixedly connected to the limiting ring 9, and the back side of the annular threaded plate 5 is fixedly connected to the limiting rod 10. When the annular threaded plate 5 rotates and moves, it can drive the limiting rod 10 to move synchronously. The rear end of the limiting rod 10 is inserted into the gap between the limiting ring 9 and the inner wall of the fixed cylinder 3. After the annular threaded plate 5 enters the interior of the fixed cylinder 3, the limiting rod 10 will be inserted into the gap between the limiting ring 9 and the inner wall of the fixed cylinder 3. At this time, the limiting ring 9 will guide and limit the movement of the limiting rod 10 to prevent the limiting rod 10 from deviating during the movement, and then limit the movement of the annular threaded plate 5 to prevent the annular threaded plate 5 from deviating during the rotation and causing it to be stuck in the fixed cylinder 3 and unable to move.

[0036] Working principle: Insert the rubber ring 7 into the fixed tube 3, and then embed the sleeve body 2 in the wall for fixation, and then pass the sleeve body 2 into the room. At this time, the rubber ring 7 is sleeved on the outside of the cable 1. Then the staff can rotate the handle 6 to drive the annular threaded plate 5 to rotate, so that the annular threaded plate 5 moves backward under the limit of the thread groove 4, and squeezes the rubber ring 7 so that the rubber ring 7 can be elastically deformed, and the gap between the cable 1 and the sleeve body 2 is further sealed. After the rubber ring 7 hardens after long-term use, the handle 6 can be directly rotated to drive the annular threaded plate 5 to rotate out of the fixed tube 3, releasing the squeezing of the rubber ring 7, so that the rubber ring 7 can be quickly taken out and replaced, which is easy to operate and maintain.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
