Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a waterproof device for cable group conduit penetrating walls. Background Technology

[0002] In the construction of infrastructure such as power and communications, it is often necessary to pass through building walls with cable groups through conduits to connect lines between different areas. Waterproofing at the wall penetration points is crucial. If the waterproofing measures are not in place, moisture can easily seep in through the gaps between the conduit and the wall and the cable, which may cause problems such as cable short circuits and corrosion, seriously affecting the normal operation of the power or communication system, and may even threaten the structural safety of the building.

[0003] Traditional methods of waterproofing cable conduits penetrating walls involve simply filling gaps with sealant. However, over time and with environmental changes, the sealant is prone to aging and cracking, leading to a decline in waterproofing performance. Furthermore, traditional methods require damaging the original waterproofing structure during cable maintenance or replacement, making subsequent repairs complex and difficult to restore to the original waterproofing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof device for cable conduit penetration through walls, in order to solve the problems mentioned in the background art of the traditional waterproof method for cable conduit penetration through walls, which uses simple sealant to fill the gaps. As time goes by and the environment changes, the sealant is prone to aging and cracking, resulting in a decline in waterproof performance. In addition, the traditional method requires the destruction of the original waterproof structure when maintaining or replacing cables, and the subsequent repair work is complicated and difficult to restore the original waterproof effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof cable conduit wall penetration device, including a limiting frame one, which and a limiting frame two are both rectangular and fit against the wall surface. A positioning sealing plate one is embedded and fixed inside the limiting frame one, and the positioning sealing plate one is penetrated by the cable body. The two ends of the cable body respectively penetrate the positioning sealing plate one and the positioning sealing plate two. The limiting frame one and the limiting frame two constitute the main structure on the outside of the wall penetration device.

[0006] The limiting frame one and the limiting frame two have the same structure, and the positioning sealing plate two is embedded and fixed inside the limiting frame two. The limiting frame one has an expansion plate one on one side wall, the limiting frame two has an expansion plate two on one side wall, and the positioning sealing plate two is parallel to the positioning sealing plate one.

[0007] The first limiting frame and the second limiting frame are respectively engaged with protective sleeves, and sealing rings are installed at both ends of the protective sleeves. The outer wall of the protective sleeves is fitted with two corrugated protruding rings, and the protective sleeves penetrate the two limiting plates.

[0008] By adopting the above technical solution, the sealing rings and corrugated protrusions at both ends of the protective sleeve adapt to the expansion and contraction of the wall through elastic deformation, thereby improving the reliability of waterproofing.

[0009] Preferably, the positioning sealing plate one and the positioning sealing plate two are evenly provided with holes through which the cable body passes, and the positioning sealing plate one has a limit ring one inside the hole, and the positioning sealing plate two has a limit ring two inside the hole.

[0010] By adopting the above technical solution, the uniform hole design within the positioning sealing plate optimizes cable arrangement and avoids sealing failure caused by compression.

[0011] Preferably, both the first limiting ring and the second limiting ring are gaskets made of silicone material, and both the first limiting ring and the second limiting ring have a cross-shaped opening structure in the middle.

[0012] By adopting the above technical solution, the high elasticity and aging resistance of the adhesive ensure a long-term sealing effect, and the star-shaped structure can adapt to cables of different diameters.

[0013] Preferably, the first expansion plate has a threaded hole for connecting expansion bolts, and the first expansion plate and the second expansion plate have the same structure, with the threaded holes of the two plates aligned.

[0014] Using the above technical solution, the threaded hole design of expansion plate one and expansion plate two allows for a secure connection to the wall via expansion bolts, preventing the device from loosening.

[0015] Preferably, the two corrugated protrusions abut against the surface of a limiting plate, and the upper and lower ends of the limiting plate are respectively embedded in a connecting plate.

[0016] Using the above technical solution, the corrugated protruding ring abuts against the limiting plate, dispersing the vibration stress of the wall and protecting the sealing structure.

[0017] Preferably, an anti-slip sleeve is sandwiched between the two limiting plates, and the holes in the anti-slip sleeve are penetrated by the cable body.

[0018] Using the above technical solution, the anti-slip sleeve and the limiting plate work together to form an additional waterproof barrier to cope with high humidity environments.

[0019] Preferably, the connecting plate is connected to the anti-slip sleeve by bolts, and the anti-slip sleeve and the connecting plate are arranged in a perpendicular direction.

[0020] By adopting the above technical solution, the bolt connection between the connecting plate and the anti-slip sleeve maximizes the sealing contact area within a limited space, thereby improving the waterproof effect.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the waterproof cable conduit wall penetration device:

[0022] 1. This waterproof device tightly wraps the cable body with the cross-shaped silicone structure of limiting ring one and limiting ring two, forming the first waterproof barrier. The sealing rings at both ends of the protective sleeve cooperate with the corrugated raised rings to prevent water from penetrating along the outer wall of the sleeve, forming the second line of defense. The vertical connection structure between the anti-slip sleeve and the connecting plate further enhances the overall sealing performance, thereby realizing the triple waterproof protection structure of this device.

[0023] 2. Limiting frame one and limiting frame two adopt a snap-fit ​​connection protective sleeve, combined with the bolt fixing structure of expansion plate one and expansion plate two, which can quickly complete the wall installation of the device. The uniform hole design of positioning sealing plate one and positioning sealing plate two, combined with the star-shaped opening of the silicone limiting ring, facilitates the provision of multiple individual accommodating spaces for cable groups, which is convenient for cables of different diameters and improves versatility.

[0024] 3. The combination structure of rectangular limiting frame and protective sleeve provides mechanical support for the cable group, effectively resisting external impact and vibration, and preventing waterproof failure due to physical damage. The corrugated protrusion ring between the rectangular limiting frame can evenly distribute external stress to the entire device through its abutment structure with the limiting plate, avoiding structural damage caused by local stress concentration. The elastic structure of the corrugated protrusion ring adapts to slight deformation of the wall or thermal expansion and contraction of the cable, and maintains sealing pressure through its own deformation, avoiding the risk of water leakage caused by structural displacement.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a waterproof device for cable group sleeves penetrating walls, including a limiting frame 1, a positioning sealing plate 2, a limiting ring 3, a cable body 4, an expansion plate 5, a second limiting frame 6, an expansion plate 7, a second positioning sealing plate 8, a second limiting ring 9, a protective sleeve 10, a corrugated protruding ring 11, a limiting plate 12, an anti-slip sleeve 13, and a connecting plate 14;

[0034] Among them, the limiting frame 1 and the limiting frame 2 6 are both rectangular and fit the wall surface. The positioning sealing plate 1 2 is embedded and fixed in the limiting frame 1 1, and the positioning sealing plate 1 2 is penetrated by the cable body 4. The two ends of the cable body 4 respectively penetrate the positioning sealing plate 1 2 and the positioning sealing plate 2 8. The limiting frame 1 1 and the limiting frame 2 6 constitute the main structure on the outside of the wall-penetrating device.

[0035] Limiting frame 1 and limiting frame 2 6 have the same structure, and a positioning sealing plate 2 8 is embedded and fixed inside the limiting frame 2 6. The side wall of limiting frame 1 has an expansion plate 5, and the side wall of limiting frame 2 6 has an expansion plate 2 7. The positioning sealing plate 2 8 is parallel to the positioning sealing plate 1 2. Holes through which the cable body 4 passes are evenly opened in the positioning sealing plate 1 2 and the positioning sealing plate 2 8. The hole of the positioning sealing plate 1 2 has a limiting ring 3, and the hole of the positioning sealing plate 2 8 has a limiting ring 2 9. Both the limiting ring 1 3 and the limiting ring 2 9 are gaskets made of silicone material. The middle of the limiting ring 1 3 and the limiting ring 2 9 is provided with a cross-shaped opening structure. The expansion plate 1 5 has a threaded hole for connecting expansion bolts, and the expansion plate 1 5 and the expansion plate 2 7 have the same structure. The positions of the threaded holes of the two are aligned.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, the limiting frame 1 and limiting frame 2 6, through the expansion plate 1 5 and expansion plate 2 7, are fixed with expansion screws to form a rigid anchoring structure, thus avoiding sealing failure due to wall settlement. The positioning sealing plate 1 2 and positioning sealing plate 2 8 within the limiting frame 1 and limiting frame 2 6 are embedded and fixed to form equidistant parallel sealing surfaces, dividing the wall-penetrating path of the cable group 4 into independent sealing units. Then, the cable body 4 passes through the limiting ring 1 3 into the protective sleeve 10, and finally exits through the limiting ring 2 9. Thus, the limiting rings 1 3 and 2 9 within the wall-penetrating hole are made of silicone and have a cross-shaped opening in the center. When the cable body 4 passes through, the silicone limiting rings use their elasticity to tightly adhere to the cable surface, preventing moisture from seeping through the gap between the cable and the positioning sealing plate, thus providing a preliminary sealing effect. The holes in the positioning sealing plate 1 2 and positioning sealing plate 2 8 facilitate the passage of the cable group through the independent sealing units, such as... Figures 1-3 As shown;

[0037] The first limiting frame 1 and the second limiting frame 6 are respectively engaged with protective sleeves 10, and sealing rings are installed at both ends of the protective sleeves 10. Two corrugated protruding rings 11 are respectively fitted on the outer wall of the protective sleeves 10, and the protective sleeves 10 pass through two limiting plates 12. The two corrugated protruding rings 11 abut against the surface of one limiting plate 12, and the upper and lower ends of the limiting plates 12 are respectively embedded in a connecting plate 14. An anti-slip sleeve 13 is sandwiched between the two limiting plates 12, and the hole in the anti-slip sleeve 13 is penetrated by the cable body 4. The connecting plate 14 is connected to the anti-slip sleeve 13 by bolts, and the anti-slip sleeve 13 and the connecting plate 14 are arranged in a perpendicular direction.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, since the protective sleeve 10 is engaged with the limiting frame 1 and the limiting frame 6 respectively, the sealing rings at both ends of the sleeve effectively prevent moisture from seeping in from the contact part between the end of the protective sleeve 10 and the limiting frame. The two corrugated protruding rings 11 on the outer wall of the protective sleeve 10 abut against the surface of the limiting plate 12. When the device is subjected to external force or undergoes a slight displacement due to environmental factors, the corrugated protruding rings 11 can absorb stress through their own deformation and maintain a sealed state. At the same time, they further prevent moisture from seeping between the outer wall of the protective sleeve 10 and other components.

[0039] The upper and lower ends of the limiting plate 12 are respectively embedded in the connecting plate 14. An anti-slip sleeve 13 is sandwiched between the two limiting plates 12, and the inner hole of the anti-slip sleeve 13 is penetrated by the cable body 4. The anti-slip sleeve 13 plays the role of fixing the position of the cable body and preventing the cable from damaging the sealing structure due to shaking or other factors. The connecting plate 14 is connected to the anti-slip sleeve 13 by bolts, which firmly connects the components together and assists in sealing, ensuring the stability of the overall structure and maintaining waterproof performance.

[0040] Working principle: When using this cable conduit wall-penetrating waterproof device, the limiting frame 1 and the limiting frame 2 6 are fixed to the wall with expansion screws to form an outer support structure. The positioning sealing plate 1 2 and the positioning sealing plate 2 8 are embedded in the frame. The silicone limiting ring 1 3 and the silicone limiting ring 2 9 in the holes tightly wrap the cable body 4 through the star-shaped opening to achieve the first layer of waterproofing. The sealing rings at both ends of the protective sleeve 10 prevent water from seeping in. The corrugated protruding ring 11 on the outer wall abuts against the limiting plate 12, absorbing stress and enhancing the seal through elastic deformation. The anti-slip sleeve 13 fixes the cable position. The connecting plate 14 is bolted to the limiting plate 12 to ensure the stability of the overall structure. The multiple seals work together to achieve efficient waterproofing and increase the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
