Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a rodent-proof control cabinet cable inlet sealing device. Background Technology

[0002] The core function of the control cabinet cable entry hole sealing device is to seal the holes through which cables pass through the cabinet. Through physical barriers and structural design, it prevents small animals such as rats and cockroaches from entering the control cabinet through the cable entry hole, avoiding short circuits, equipment failures or shutdowns caused by cable chewing. It also improves the overall performance of electrical equipment in terms of safety, reliability and maintainability, and is an indispensable protective component in industrial automation and electrical systems.

[0003] Existing control cabinet cable inlet sealing devices are mostly simple seals with poor versatility. They are difficult to adapt to cables of different thicknesses and are prone to gaps, allowing rats to crawl in or dust and moisture to enter. In terms of strength, some of the sealing devices are made of materials that are not strong enough and are easily chewed through by rats, thus failing to provide effective protection and failing to meet the requirements for efficient rat-proofing and anti-clogging. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rodent-proof control cabinet cable inlet sealing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rodent-proof control cabinet cable inlet sealing device includes a rubber plug, a conduit, and a control cabinet side panel. A cable hole is formed through one side of the control cabinet side panel, and the rubber plug is inserted through the cable hole. An elastic gripper A is fixedly connected to the inner end of the rubber plug near the inner side of the control cabinet side panel. The elastic gripper A is generally funnel-shaped, with an elastic gripper B on one side of its smallest outlet end. The elastic gripper B is fixedly connected to the rubber plug, and its structure is the same as that of the elastic gripper A. Several extension plates are integrally connected to the smallest outlet end of the elastic gripper B. One end of the conduit is fixedly connected inside the rubber plug, and the extension plates are sleeved inside the conduit. Several elastic sealing modules are provided in the interlayer between the inner wall of the conduit and the extension plates. The inner side of each elastic sealing module is fixedly connected to the outer side of the extension plates, and the outer side of each elastic sealing module is integrally connected to the inner wall of the conduit.

[0007] As a further embodiment of this utility model, a metal mesh is fixedly connected in the tube layer of the conduit, and the metal mesh is isolated from the elastic sealing module through the tube layer of the conduit. A flange is fixedly connected to the outside of the end of the conduit near the elastic gripper B.

[0008] As a further embodiment of this utility model, one side of the flange is attached to the outer wall of the control cabinet side plate and fixedly connected by bolts, and the flange is fixedly connected to the outside of the control cabinet side plate by bolts.

[0009] As a further embodiment of this utility model, an elastic metal guard plate is provided on one side of the flange, and several magnets are fixedly connected to the vertical opening of the elastic metal guard plate. The vertical openings of the elastic metal guard plate overlap each other and are magnetically attracted and bonded by the magnets.

[0010] As a further embodiment of this utility model, the elastic metal guard plate is sleeved on the outside of the conduit, and a number of anti-rodent spikes are fixedly installed on the outside of the elastic metal guard plate and arranged radially. A handle is integrally connected to the outside of the elastic metal guard plate, and the two ends of the handle are located in the gaps between the number of anti-rodent spikes.

[0011] As a further embodiment of this utility model, a positioning plate is provided on the side of the control cabinet away from the flange. The positioning plate is covered by a rubber plug and part of the control cabinet side plate. The positioning plate is fixedly connected to a rubber ring on one side of the rubber plug by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. After the rubber plug is inserted into the wiring hole on the side panel of the control cabinet, the funnel-shaped structure of the elastic gripper A and elastic gripper B can expand elastically as the cable is inserted. When the cable passes through, the contraction force of the two grippers will hold the cable tightly. The double-layer elastic gripper design enhances the sealing performance of the cable. Even if the cable thickness is different, it can fit tightly through elastic deformation, effectively preventing rats from gnawing on the cable or crawling into the control cabinet through the hole. When the extension plate moves with the cable, it will drive the elastic sealing module to deform, further filling the gap between the cable and the conduit. The cooperation between the extension plate and the elastic sealing module further improves the sealing accuracy and reduces the entry of dust and moisture.

[0014] 2. The metal mesh inside the conduit enhances its strength and improves its rodent-proof capabilities, preventing rats from entering the control cabinet by chewing through the conduit. Simultaneously, an elastic metal protective plate is fitted over the conduit, with magnets at its vertical openings that can attract and close, forming a protective layer around the conduit. The elasticity of the metal protective plate adapts to conduits of different diameters, enhancing the device's versatility. Rodent-proof spikes are radially fixed to the outside of the elastic metal protective plate; when rats try to climb, the spikes will block them, creating a physical barrier that increases the difficulty of climbing and effectively prevents them from approaching the conduit.

[0025] Reference Figures 1-6 A rodent-proof control cabinet cable inlet sealing device includes a rubber plug 1, a conduit 2, and a control cabinet side plate 4. A cable hole 401 is provided through one side of the control cabinet side plate 4, and the rubber plug 1 is inserted into the cable hole 401. An elastic gripper A101 is fixedly connected to the end of the rubber plug 1 closest to the inside of the control cabinet side plate 4. The elastic gripper A101 is generally funnel-shaped, and an elastic gripper B102 is provided on one side of its smallest outlet end. The elastic gripper B102 is fixedly connected to the rubber plug 1. The gripper B102 has the same structure as the elastic gripper A101. The minimum outlet end of the elastic gripper B102 is integrally connected with several extension plates 103. One end of the tubing 2 is fixedly connected to the inside of the rubber stopper 1. The extension plates 103 are sleeved inside the tubing 2. Several elastic sealing modules 202 are provided in the interlayer between the inner wall of the tubing 2 and the extension plates 103. The inner side of the elastic sealing modules 202 is fixedly connected to the outside of the extension plates 103, and the outer side of the elastic sealing modules 202 is integrally connected to the inner wall of the tubing 2.

[0026] In use, after the rubber plug 1 is inserted into the wiring hole 401 of the control cabinet side plate 4, the bucket-shaped structure of the elastic gripper A101 and elastic gripper B102 can expand elastically as the cable is inserted. When the cable passes through, the contraction force of the two grippers will hold the cable tightly. The double-layer elastic gripper design enhances the sealing performance of the cable. Even if the cable thickness is different, it can fit tightly through elastic deformation, effectively preventing rats from gnawing on the cable or crawling into the control cabinet through the hole. When the extension plate 103 moves with the cable, it will drive the elastic sealing module 202 to deform, further filling the gap between the cable and the conduit 2. The cooperation between the extension plate 103 and the elastic sealing module 202 further improves the sealing accuracy and reduces the entry of dust and moisture.

[0027] In this embodiment, a metal mesh 201 is fixedly connected in the pipe layer of the conduit 2. The metal mesh 201 and the elastic sealing module 202 are isolated through the pipe layer of the conduit 2. A flange 203 is fixedly connected to the outside of the end of the conduit 2 near the elastic gripper B102.

[0028] In use, the metal mesh 201 inside the conduit 2 can enhance the strength of the conduit 2 and improve the rodent-proof ability of the conduit 2, preventing rodents from entering the control cabinet by biting through the conduit 2. The flange 203 is fixed to the outside of the control cabinet side plate 4 by bolts, tightly connecting the conduit 2 to the side plate to form a stable support.

[0029] In this embodiment, one side of the flange 203 is attached to the outer wall of the control cabinet side plate 4 and is fixedly connected by bolts. The flange 203 is fixedly connected to the outside of the control cabinet side plate 4 by bolts.

[0030] During use, the fixing of flange 203 makes the connection between the entire sealing device and the side plate more secure. The bolt fixing method ensures a tight connection between the sealing device and the side plate, preventing the device from shifting due to vibration and other factors, ensuring the stability of the sealing structure, enhancing the overall reliability of rodent protection, preventing the device from loosening and causing sealing failure, and providing an installation foundation for the external protective structure.

[0031] In this embodiment, an elastic metal guard plate 3 is provided on one side of the flange 203. Several magnets 301 are fixedly connected to the vertical opening of the elastic metal guard plate 3. The vertical openings of the elastic metal guard plate 3 overlap each other and are magnetically attracted and bonded by the magnets 301.

[0032] In use, the elastic metal guard plate 3 is fitted over the outside of the conduit 2. The magnet 301 at its vertical opening can be attracted and closed, forming a protective layer that wraps around the conduit 2. When the cable needs to be repaired, the elastic metal guard plate 3 can be pried open, and after repair, it can be closed again by the magnet 301. The elastic metal guard plate 3 can prevent rats from directly gnawing on the conduit 2. The magnet 301 connection is easy to install and remove and does not affect cable maintenance. The elasticity of the elastic metal guard plate 3 can adapt to conduits 2 of different diameters, improving the versatility of the device.

[0033] In this embodiment, the elastic metal guard plate 3 is sleeved on the outside of the conduit 2. Several anti-rat spikes 302 are fixedly installed on the outside of the elastic metal guard plate 3 and arranged radially. A handle 303 is integrally connected to the outside of the elastic metal guard plate 3, and the two ends of the handle 303 are located in the gaps between the several anti-rat spikes 302.

[0034] When in use, the handle 303 is placed in the gap of the anti-rat spikes 302 to facilitate the operator to open and close the guard plate. The anti-rat spikes 302 are fixed radially on the outside of the elastic metal guard plate 3. When rats climb, they will be blocked by the spikes. The radial design of the anti-rat spikes 302 forms a physical barrier, increasing the difficulty for rats to climb and effectively preventing them from approaching the conduit 2.

[0035] In this embodiment, a positioning plate 5 is provided on the side of the control cabinet side plate 4 away from the flange 203. The positioning plate 5 covers the rubber plug 1 and part of the control cabinet side plate 4. The positioning plate 5 is fixedly connected to the rubber ring on one side of the rubber plug 1 by bolts.

[0036] In use, the positioning plate 5 covers the rubber plug 1 and part of the side plate and is fixed to the rubber ring of the rubber plug 1 with bolts, pressing the rubber plug 1 into the wiring hole 401 of the control cabinet side plate 4. The fixing of the positioning plate 5 makes the rubber plug 1 fit more tightly with the side plate, preventing the rubber plug 1 from loosening due to cable pulling or vibration, ensuring that the elastic gripper always maintains a good sealing state, and improving the overall anti-rodent bite effect.

[0037] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The rubber plug 1 is inserted into the wiring hole 401 of the control cabinet side plate 4 and initially fixed by interference fit. The elastic gripper A101 and elastic gripper B102 inside the rubber plug 1 are in the shape of a bucket. When the cable is inserted, it expands elastically and contracts to hug the cable after passing through, forming the first layer of seal. The extension plate 103 moves with the cable, causing the elastic sealing module 202 to deform and fill the gap between the cable and the conduit 2, forming the second layer of seal. One end of the conduit 2 is fixed to the rubber plug 1, and the internal metal mesh 201 enhances the strength. The other end is connected to the side plate by bolts through the flange 203 to ensure a stable fit. The elastic metal guard plate 3 is fitted over the conduit 2. The magnet 301 at its vertical opening is attracted and closed. The anti-rat spikes 302 are fixed radially on the outside of the guard plate. The handle 303 is installed in the gap between the spikes. The positioning plate 5 covers the rubber plug 1 and part of the side plate and is pressed onto the rubber ring of the rubber plug 1 by bolts to prevent the rubber plug 1 from shifting. This device employs a multi-layered structure to prevent rodent bites and blockages. Elastic grippers A101 and B102 tightly hold the cable, while the conduit 2 and metal mesh 201 prevent biting. An elastic metal guard plate 3 provides barrier protection, and radial rodent spikes 302 form a physical barrier, creating a multi-layered rodent-proof system. The double-layered grippers and elastic sealing module 202 can accommodate cables of varying thicknesses, and the elastic metal guard plate 3 adapts to different pipe diameters, providing comprehensive protection. Simultaneously, the tight fit between elastic grippers A101, B102, and the elastic sealing module 202 prevents dust, moisture, and debris from entering, avoiding cable malfunctions or poor heat dissipation due to accumulation. The tight connections of all components prevent the intrusion of insects and other foreign objects, ensuring internal cleanliness and reducing the risk of malfunction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
