Description

Technical Field

[0001] This application relates to the field of circuit installation technology, and in particular to a dual-plate adjustable frame junction box. Background Technology

[0002] A junction box is a device used to protect the connection points of electrical circuits. Its main function is to enclose the wire joints in a safe space, preventing the joints from being directly exposed, thereby preventing leakage, short circuits, mechanical damage, or intrusion of foreign objects.

[0003] According to the preset wiring, the junction box is fixed to the wall, equipment or bracket by means of threaded connection or embedded in the preset groove, so as to ensure the stability of the junction box and avoid damage to the wiring by external force.

[0004] Regarding the aforementioned technologies, the inventor believes that existing junction boxes require workers to use tools for disassembly and assembly during installation. Especially in humid environments such as rainy seasons and under bridges, it is necessary to regularly check the condition of the internal wiring. Each inspection requires tools for disassembly and assembly, making the operation cumbersome and inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a dual-plate adjustable frame junction box to improve the problem of inconvenient junction box replacement.

[0006] The technical solution for the double-plate adjustable frame junction box provided in this application is as follows:

[0007] A double-plate adjustable frame junction box includes a base plate, which is provided with several horizontal plates and vertical plates. A top plate is provided at the end of each horizontal plate away from the base plate, and several wiring ports are provided on each vertical plate. The base plate is provided with several limiting screws, and each limiting screw is fitted with an elastic connector. One end of the elastic connector is connected to the base plate, and the other end is connected to the top plate. A limiting nut is provided at the end of each limiting screw that passes through the top plate, and the limiting nut is provided with an extension plate.

[0008] By adopting the above technical solution, the top plate is pressed tightly by adjusting the fit depth between the limit nut and the limit screw. Under the action of the elastic connector, the top plate always remains in contact with the limit nut. Workers can easily adjust the fit depth between the limit nut and the limit screw by manually turning the extension plate, thereby improving the problem of inconvenient disassembly and assembly of the junction box.

[0009] Optionally, the base plate has several rotating parts at both ends, and the other end of the rotating parts connected to the base plate is connected to the longitudinal plate. The longitudinal plate has several insert plates, the transverse plate has slots for inserting the insert plates, the insert plates have snap-fit ​​connectors, and the slots have snap-fit ​​blocks that can engage with the snap-fit ​​connectors.

[0010] By adopting the above technical solution, when facing humid environments such as plum rains and underpasses, workers can manually rotate and open the longitudinal plate, thereby conveniently controlling the connection status between the longitudinal plate and the transverse plate, and reducing the moisture content inside the junction box by ventilation or using tools such as blowers.

[0011] Optionally, the slot is provided with a placement groove for placing the locking block, the bottom of the placement groove is provided with an elastic element, the elastic element is connected to the locking block, and the locking block is provided with a pull rod that passes through the horizontal plate.

[0012] By adopting the above technical solution, when the insert plate is inserted into the slot, the locking connector and the locking block form an abutment state, and the locking block squeezes the elastic element into the placement groove, which facilitates the passage of the locking connector; when the engagement is released, it is only necessary to pull the pull rod to retract the locking block into the placement groove, which can quickly release the locking engagement, reduce the wear of the locking block, and thus effectively extend the service life of the workpiece.

[0013] Optionally, the card connector is provided with guide fillet.

[0014] By adopting the above technical solution, when the insert plate and the slot are inserted and mated, a guide rounded corner is provided on the mating end face of the card connector and the card block. During the process of inserting the insert plate into the slot, the rounded corner can guide the card connector to slide smoothly into the card block. After being inserted into place, the side of the card connector without the guide rounded corner is in close contact with the card block, thereby facilitating the quick insertion of the insert plate while ensuring the stable mating between the insert plate and the slot.

[0015] Optionally, the engaging block is provided with a bevel, which can abut against the guide fillet.

[0016] By adopting the above technical solution, when the insert plate and the slot are engaged, the inclined surface on the locking block and the guide rounded corner on the locking connector form a sliding contact. The combination design of the inclined surface and the guide rounded corner can guide the locking connector to smoothly form a locking state with the locking block. At the same time, after the locking is in place, it is locked by the geometric structure, thereby ensuring the connection stability between the locking connector and the locking block.

[0017] Optionally, the placement slot is provided with a blocking block.

[0018] By adopting the above technical solution, the blocking block and the lower end of the locking block abut against each other, which can effectively prevent the locking block from coming out of the placement groove. When the locking block retracts into the placement groove under the action of the elastic element, the limiting effect of the blocking block can ensure that the locking block can reliably engage with the locking connector when it resets under the elastic support, and can also ensure the normal working performance of the locking block.

[0019] Optionally, the placement slot is provided with a securing slot for the blocking block to be secured.

[0020] By adopting the above technical solution, the embedding groove can position and install the blocking block at the slot opening, while ensuring that the upper surface of the blocking block is coplanar with the side wall of the slot, thereby reducing the interference of the blocking block on the insertion operation of the insert plate.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By adjusting the fit depth between the limit nut and the limit screw to press the top plate tightly, the top plate always remains in contact with the limit nut under the action of the elastic connector. Workers can easily adjust the fit depth between the limit nut and the limit screw by manually turning the extension plate, thereby improving the problem of inconvenient disassembly and assembly of the junction box.

[0023] 2. When facing damp environments such as plum rains or under bridges, workers can manually rotate and open the longitudinal plate to easily control the connection between the longitudinal and transverse plates, thereby reducing the moisture content inside the junction box through ventilation or the use of tools such as blowers;

[0024] 3. When the insert plate is inserted into the slot, the locking connector and the locking block form an abutment state. The locking block squeezes the elastic element and retracts into the placement groove, facilitating the passage of the locking connector. To release the engagement, simply pull the lever to retract the locking block into the placement groove, which can quickly release the locking engagement, reduce wear on the locking block, and thus effectively extend the service life of the workpiece.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] A double-plate adjustable frame junction box, as shown in the reference Figure 1 The system includes a horizontal base plate 1, which is provided with several horizontal plates 11 and vertical plates 12. In this embodiment, both the horizontal plates 11 and the vertical plates 12 are vertical plates. The number of both the horizontal plates 11 and the vertical plates 12 is preferably two. The base plate 1 and the horizontal plates 11 are fixedly connected by welding.

[0033] Reference Figure 1 A horizontal top plate 13 is provided at the end of the horizontal plate 11 away from the bottom plate 1. The top plate 13 is provided with a raised shell 15 in the shape of a hollow square box with a transparent bottom by welding. When the top plate 13 is close to the bottom plate 1, the hollow raised shell 15 can increase the distance between the top plate 13 and the wires in the junction box, reducing the possibility of the top plate 13 affecting the wire connection. The side wall of the top plate 13 has a sealing ring to keep the inside of the junction box closed.

[0034] Reference Figure 1 and Figure 2 The base plate 1 has several rotating parts 3 fixed at both ends. The other end of the rotating parts 3 connected to the base plate 1 is connected to a longitudinal plate 12. The longitudinal plate 12 is provided with several wiring ports 14. In this embodiment, the rotating parts 3 are preferably hinges. The number of rotating parts 3 is preferably 2, and the number of wiring ports 14 is preferably 2. The rotating longitudinal plate 12 facilitates observation of the wiring situation inside the junction box.

[0035] Reference Figure 2 and Figure 3 The base plate 1 is provided with a plurality of limiting screws 2, and the limiting screws 2 are fitted with elastic connectors 21. One end of the elastic connector 21 is connected to the base plate 1, and the other end is connected to the top plate 13. A limiting nut 22 is provided at one end of the limiting screw 2 that passes through the top plate 13. In this embodiment, the number of limiting screws 2 is preferably 4, and the elastic connector 21 is preferably a spring. By adjusting the fitting depth between the limiting nut 22 and the limiting screw 2, the top plate 13 is pressed tightly. Under the action of the elastic connector 21, the top plate 13 always remains in contact with the limiting nut 22.

[0036] Reference Figure 2 and Figure 3 The limit nut 22 is provided with a vertical plate-shaped extension plate 23 by welding. Workers can adjust the tightness of the fit between the limit nut 22 and the limit screw 2 by manually turning the extension plate 23, reducing the original cumbersome disassembly and assembly procedures, thereby improving the problem of inconvenient disassembly and assembly of the junction box.

[0037] Reference Figure 2 and Figure 4The longitudinal plate 12 is fixedly provided with several long plate-shaped insert plates 31 by welding. The transverse plate 11 is provided with slots 32 for inserting the insert plates 31. The insert plates 31 are fixedly provided with square-shaped snap-fit ​​connectors 33 by welding. The slots 32 are provided with snap-fit ​​blocks 34 that can engage with the snap-fit ​​connectors 33. The snap-fit ​​blocks 34 are square-shaped. When the insert plate 31 is inserted into the slot 32, the snap-fit ​​connectors 33 and snap-fit ​​blocks 34 form a snap-fit ​​structure. Through the tight cooperation between the two, the insert plate 31 can be effectively prevented from falling out of the slot 32, thereby reducing the impact on the overall stability of the junction box.

[0038] Reference Figure 4 The slot 32 is provided with a placement groove 4 for placing the locking block 34. An elastic element 41 is provided at the bottom of the placement groove 4. The elastic element 41 is connected to the locking block 34. The locking block 34 is provided with a pull rod 36 that passes through the horizontal plate 11. In this embodiment, the elastic element 41 is preferably a spring, and the pull rod 36 is in the shape of a round rod. When the insert plate 31 is inserted into the slot 32, the locking connector 33 and the locking block 34 form an abutment state. The locking block 34 squeezes the elastic element 41 and retracts it into the placement groove 4, which facilitates the passage of the locking connector 33. When the engagement is released, it is only necessary to pull the pull rod 36 to retract the locking block 34 into the placement groove 4 to quickly release the locking engagement.

[0039] Reference Figure 4 and Figure 5 The snap-fit ​​connector 33 is provided with an arc-shaped guide rounded corner 35, and the snap-fit ​​block 34 is provided with a slope 37 that can abut against the guide rounded corner 35. In this embodiment, the arc of the guide rounded corner 35 is preferably a quarter circle, and the slope angle of the slope 37 is preferably 45 degrees. When the insert plate 31 and the slot 32 are engaged, the slope 37 on the snap-fit ​​block 34 and the guide rounded corner 35 on the snap-fit ​​connector 33 form a sliding contact, guiding the snap-fit ​​connector 33 to smoothly form a snap-fit ​​state with the snap-fit ​​block 34.

[0040] Reference Figure 5 The placement groove 4 is provided with a square ring-shaped blocking block 42. The blocking block 42 abuts against the lower end of the locking block 34, which can effectively prevent the locking block 34 from coming out of the placement groove 4. When the locking block 34 retracts into the placement groove 4 under the action of the elastic member 41, the limiting effect of the blocking block 42 can ensure that the locking block 34 can reliably engage with the locking connector 33 when it is reset under elastic support, and can also ensure the normal working performance of the locking block 34.

[0041] Reference Figure 5 The placement slot 4 is provided with a fixing slot 43 for the blocking block 42 to be fixed. The fixing slot 43 can position the blocking block 42 at the opening of the placement slot 4, while ensuring that the upper surface of the blocking block 42 is coplanar with the side wall of the slot 32, thereby reducing the interference of the blocking block 42 on the insertion operation of the insert plate 31.

[0042] The implementation principle of this application embodiment is as follows:

[0043] Install the base at the pre-set wiring location, pass the wire through the wiring port 14 and connect it inside the junction box. Then, align the top plate 13 with the limit screw 2 for installation. The worker can manually turn the extension plate 23 to tighten the limit nut 22 along the limit screw 2. When it is necessary to open the junction box, simply disengage the limit nut 22 from the limit screw 2 by hand. No tools are needed to disassemble and install the junction box, improving the convenience of disassembly and assembly operations when regularly inspecting the junction box in humid environments.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
