Description

Technical Field

[0001] This utility model belongs to the field of low-voltage circuit technology, specifically a circuit protection structure. Background Technology

[0002] Low-voltage electricity generally refers to DC circuits or audio, video, network, and telephone lines. AC voltage is generally below 36V. Household appliances such as telephones, computers, television signal inputs (cable TV lines), and audio equipment (output lines) are all low-voltage electrical equipment. The main difference between high-voltage and low-voltage electricity is their purpose. High-voltage electricity is used as a power source, while low-voltage electricity is used as a signal source.

[0003] Because low-voltage wiring poses fewer safety hazards, it does not require the same construction standards as high-voltage wiring. Wiring can be done according to needs. When running straight wires, they can be directly fixed with wire clips. Especially when encountering corners, the wires need to be strongly fixed and protected to prevent the wires from rubbing against the corner and getting damaged.

[0004] Through daily use, it was found that after the cable is fixed with the cable clip, it is slightly inconvenient to disconnect the clip when maintenance is needed. The clip needs to be pulled out, which is not convenient to use. Therefore, a new type of protective structure needs to be designed to protect the cable, while also meeting the requirements of easy installation and convenient maintenance and replacement during use. Utility Model Content

[0005] The purpose of this utility model is to provide a circuit protection structure in order to solve the above-mentioned problems.

[0006] The technical solution adopted by this utility model is as follows: a line protection structure, wherein an isolation plate is installed on the side of the wall by expansion bolts, a wire trough is installed on the front of the isolation plate, and connecting ears are integrally formed symmetrically along the side of the wire trough. A connecting component is provided between the connecting ears and the isolation plate, and a protective component for protecting the cable is provided on the front of the wire trough.

[0007] The connecting components include: outer pin, hollow groove, anti-detachment block, support block, spring, expansion bolt, expansion head, and buffer recess;

[0008] The connecting ear and the isolation plate are movably connected by an outer pin through a connecting hole. The end of the outer pin is integrally provided with a buffer recess, and the inside of the outer pin is hollow and provided with a hollow groove. The other end of the outer pin is integrally provided with a spring piece, and the spring piece is arranged in a two-lobed manner. The inner and outer walls of the two spring pieces are integrally provided with a support block and an anti-detachment block.

[0009] The outer pin is internally slidably connected with an expansion bolt, and the end of the expansion bolt is integrally provided with an expansion head. The expansion head is spherical, and the surfaces of the two support blocks are provided with grooves that fit with the expansion head.

[0010] The protective component includes: a crease, a bayonet, a cover plate, and a locking head; a cover plate is rotatably connected above the wire groove via the crease, a locking head is integrally provided at the end of the cover plate, and a bayonet is integrally provided below the wire groove; the surface of the locking head is provided with a raised edge, and the locking head is connected to the bayonet.

[0011] The end of the cable tray is movably fitted with a sleeve head, and there are two sleeve heads, which are connected by a corrugated flexible tube.

[0012] The other end of the expansion bolt is provided with a pressure head, which fits into the buffer recess, and the depth of the buffer recess is greater than the thickness of the pressure head.

[0013] The material of the wire groove, cover plate, outer pin, and expansion bolt is PE plastic.

[0014] Foam is attached to the opposite sides of the groove and the cover plate.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the rotatable cover plate allows the clip head and the clip to elastically deform and snap together, thus completing the closure of the cable tray. This flip-top disassembly and assembly method is more convenient to use, facilitates cable maintenance, and is flexible in use.

[0017] 2. In this utility model, when the wire trough needs to be installed on the isolation plate, the outer pin can be inserted into the connecting hole between the connecting ear and the isolation plate, and the expansion bolt can be inserted into the hollow groove so that the expansion head contacts the support block. Then, the pressure between the anti-detachment block and the connecting hole is used to achieve the purpose of limiting the position. When the outer pin needs to be removed, simply press the pressure head again so that the pressure head enters the buffer recess, and at the same time, the expansion head and the support block no longer interact. Then, pull out the outer pin. This structure is convenient to use, facilitates the installation and use of the wire trough, and is easy to disassemble and assemble.

[0018] 3. In this utility model, two caps are used to cover the outside of two cable trays, and the corrugated flexible conduit changes with the angle of the corner of the wall to protect the cable. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] In this utility model:

[0031] Reference Figure 1-9 A line protection structure, wherein an isolation plate 2 is installed on the side of the wall 1 by expansion bolts, a wire trough 3 is installed on the front of the isolation plate 2, and a connecting ear 301 is integrally formed symmetrically along the side of the wire trough 3. A connecting component is provided between the connecting ear 301 and the isolation plate 2, and a protective component for protecting the cable is provided on the front of the wire trough 3.

[0032] The connecting components include: outer pin 5, hollow groove 501, anti-detachment block 502, support block 503, spring piece 504, expansion bolt 6, expansion head 601, and buffer recess 7;

[0033] An outer pin 5 is movably connected between the connecting ear 301 and the isolation plate 2 through a connecting hole. The end of the outer pin 5 is integrally provided with a buffer recess 7. The outer pin 5 is hollow and has a hollow groove 501. The other end of the outer pin 5 is integrally provided with a spring piece 504, which is arranged in a two-lobed manner. The inner and outer walls of the two spring pieces 504 are integrally provided with a support block 503 and an anti-detachment block 502.

[0034] The outer pin 5 has an internal sliding connection with an expansion bolt 6, and the end of the expansion bolt 6 is integrally provided with an expansion head 601. The expansion head 601 is spherical, and the surfaces of the two support blocks 503 are provided with grooves that fit with the expansion head 601. The other end of the expansion bolt 6 is provided with a pressure head 602, which fits with a buffer recess 7. The depth of the buffer recess 7 is greater than the thickness of the pressure head 602. When the wire groove 3 needs to be installed on the isolation plate 2, the outer pin 5 can be inserted into the connection hole between the connecting ear 301 and the isolation plate 2. At this time, the anti-detachment block 502 extends to the other side of the isolation plate 2. Then, the expansion bolt 6 is inserted into the hollow groove 501, so that the expansion head 601 contacts the support block 503. The concave-convex connection achieves the purpose of limiting and forms a support. The diameter of the anti-detachment block 502 is greater than the diameter of the connection hole to prevent the spring 504 from retracting. The pressure between the anti-detachment block 502 and the connection hole achieves the purpose of limiting.

[0035] When it is necessary to remove the outer pin 5, simply press the pressure head 602 again. The pressure head 602 enters the buffer recess 7, which simultaneously causes the expansion head 601 and the support block 503 to no longer interact, and the spring piece 504 is no longer supported. Then pull out the outer pin 5. This structure is easy to use and facilitates the installation and use of the wire groove 3.

[0036] The protective components include: crease 302, bayonet 303, cover plate 304, and clip 3041;

[0037] A cover plate 304 is rotatably connected above the cable tray 3 via a crease 302. A clip 3041 is integrally provided at the end of the cover plate 304, and a slot 303 is integrally provided below the cable tray 3. The surface of the clip 3041 is provided with a raised edge, and the clip 3041 is connected to the slot 303. When the cable is placed into the cable tray 3, the cover plate 304 is rotated, so that the clip 3041 and the slot 303 undergo elastic deformation and snap together, thus completing the closure of the cable tray 3. This flip-top disassembly and assembly method is more convenient to use and facilitates cable maintenance.

[0038] The cable tray 3 is movably fitted with a sleeve head 4, and there are two sleeve heads 4. The two sleeve heads 4 are connected by a corrugated flexible tube 401. The two sleeve heads 4 are fitted over the outside of the two cable trays 3. The corrugated flexible tube 401 changes with the angle of the corner of the wall to protect the cable.

[0039] Furthermore, the cable tray 3, cover plate 304, outer pin 5, and expansion bolt 6 are made of PE plastic. PE plastic has the advantages of high strength, good toughness, high rigidity, heat resistance, and cold resistance. It also has good resistance to environmental stress cracking and tear strength, and can undergo some elastic deformation to improve durability.

[0040] Furthermore, foam 305 is attached to the opposite sides of the cable tray 3 and the cover plate 304. Foam 305 can be selectively attached to the opposite sides of the cable tray 3 and the cover plate 304. The foam 305 has self-adhesive backing, making it easy to use. The attached foam 305 can squeeze the cable to achieve the purpose of fixing the cable, which is more convenient.

[0041] Furthermore, putty can be used to seal the ends of the cable tray.

[0042] Working principle: First, install the isolation plate 2 onto the wall 1 using expansion bolts. Beforehand, cover the cable with the head cap 4 and corrugated flexible conduit 401. Then, open the cover plate 304 and place the cable into the cable tray 3. You can selectively attach foam 305 to the opposite sides of the cable tray 3 and cover plate 304. The foam 305 has self-adhesive backing for easy use. The attached foam 305 can compress the cable to secure it. Next, rotate the cover plate 304, causing the clip 3041 and the clip 303 to elastically deform and engage, thus sealing the cable tray 3. This flip-top installation method is more convenient and facilitates cable maintenance. Then, when installing the cable tray 3 onto the isolation plate 2, insert the outer pin 5 into the connecting hole between the connecting ear 301 and the isolation plate 2. The anti-detachment block 502 extends to the other side of the isolation plate 2. Then, the expansion bolt 6 is inserted into the hollow groove 501, so that the expansion head 601 contacts the support block 503. The concave-convex connection achieves the purpose of limiting and forming a support to prevent the spring piece 504 from retracting. Then, the pressure between the anti-detachment block 502 and the connection hole achieves the purpose of limiting. When it is necessary to remove the outer pin 5, simply press the pressure head 602 again. The pressure head 602 enters the buffer recess 7, and at the same time, the expansion head 601 and the support block 503 no longer interact. The spring piece 504 is no longer supported. Then, pull out the outer pin 5. This structure is convenient to use and facilitates the installation and use of the cable tray 3. Finally, the two caps 4 are put on the outside of the two cable trays 3. The corrugated hose 401 changes with the angle of the corner to protect the cable.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
