Description

A quick-connect mechanism for electrical boxes Technical Field

[0001] This utility model relates to the field of electrical box technology, and in particular to a quick connection mechanism for electrical boxes. Background Technology

[0002] An electrical box is a device that assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel, mainly used in low-voltage power distribution systems. Its main function is to connect, disconnect, and protect electrical circuits to ensure the safe operation of the power system.

[0003] Currently, electrical components (such as circuit breakers, contactors, and relays) inside traditional electrical boxes are typically mounted on DIN rails. These rails only support horizontal adjustment, resulting in limited vertical space. During wiring operations, the narrow operating area is easily obstructed by the circuit breaker itself, affecting wiring efficiency. This is especially problematic in complex wiring layouts, making it difficult to flexibly adapt to different wiring scenarios and achieve rapid connection, thus impacting the operational efficiency of construction workers.

[0004] Therefore, we propose a quick-connection mechanism for electrical boxes to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a quick connection mechanism for electrical boxes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick connection mechanism for an electrical box, comprising a base and a body, wherein a sliding groove is provided on one side of the base, and a screw is rotatably provided in the sliding groove via an adjusting component, and a screw block is threaded on the screw, the screw block slidingly contacting the inner wall of the sliding groove;

[0007] The screw block is detachably mounted on the device body. Each of the two ends of the device body is symmetrically provided with a plug port, and each plug port is provided with a pressure cap corresponding to the thread.

[0008] Preferably, the adjustment assembly consists of an isolation cover, a rotating cap, protrusions, a driving wheel, and a driven wheel. The isolation cover is located at the top notch of the base, the driving wheel is rotatably located inside the isolation cover, the rotating cap is located at the shaft end of the driving wheel and on the upper surface of the isolation cover, and the protrusions are equidistantly located on the outer wall of the rotating cap.

[0009] Preferably, the driven wheel is located at the shaft end of the screw, and the driving wheel and the driven wheel mesh with each other and are both located inside the isolation cover.

[0010] Preferably, the outer wall of the device is symmetrically provided with writing seats, the writing seats are provided with writing areas, the protruding part of the device is glued with an identification plate, the identification plate records the model of the device, and the device is provided with a rotating operating button.

[0011] Preferably, the base has a track groove on the side facing away from the slide groove, the inner wall of the track groove has a slot, and the screw block has a positioning hole at the corresponding position.

[0012] Preferably, a threaded groove is provided at a corresponding position on the outer wall of the device, and the bolt structure passes through the strip hole and the positioning hole in sequence and is threaded onto the threaded groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] During the use of this utility model electrical box quick connection mechanism, electrical components such as circuit breakers inside the electrical box can have their bases placed on the circuit breaker body during installation. During the connection process, the bolt structure is inserted into the positioning hole through the slot and finally screwed into the reserved screw groove of the body, thus fixing the bolt block and the body together.

[0015] Then, it can be slidably inserted into the pre-set guide rail inside the electrical box through the track groove on the base. During the wiring process, when the space above the device is insufficient, the device can be adjusted by adjusting the components to move up and down on the base, thereby increasing the wiring space above the device. When the space below the device is insufficient, the device can be adjusted by adjusting the components to move up on the base, thereby increasing the wiring space below the device.

[0016] When the adjustment component is working, the operator manually rotates the cap block, which drives the drive wheel to rotate. Through the meshing action of the gear teeth between the drive wheel and the driven wheel, the screw is driven to rotate. Under the principle of the lead screw, the rotation of the screw is converted into the lifting and lowering action of the device on the base.

[0017] When wiring, insert the wire end into the plug hole, and then rotate the clamp cap with a tool. The thread engagement between the clamp cap and the plug hole will press the wire end tightly into the device body to complete the wiring operation.

[0018] Furthermore, the power line corresponding to the circuit breaker can be written on the writing base for easy retrieval by personnel;

[0019] This utility model, through the sliding cooperation between the base and the guide rail, combined with the screw drive design of the adjustment component, allows the circuit breaker to be flexibly raised and lowered in the vertical direction. The meshing transmission between the driving wheel and the driven wheel achieves precise control, breaking through the limitation of traditional guide rails being limited to horizontal adjustment, significantly expanding the wiring space, adapting to complex working conditions, and achieving the purpose of rapid connection.

[0027] Example 1

[0028] As shown in Figures 1-4, the present invention proposes a quick connection mechanism for an electrical box, which includes a base 1 and a body 2. A groove 9 is provided on one side of the base 1. A screw 6 is rotatably provided in the groove 9 through an adjusting component 4. A screw block 5 is threaded on the screw 6. The screw block 5 slides in contact with the inner wall of the groove 9.

[0029] The screw block 5 is detachably mounted on the body 2. A track groove 3 is provided on the side of the base 1 facing away from the sliding groove 9. A slotted hole 7 is provided on the inner wall of the track groove 3. A positioning hole 8 is provided at the corresponding position of the screw block 5. A threaded groove is provided at the corresponding position on the outer wall of the body 2. The bolt structure passes through the slotted hole 7 and the positioning hole 8 in sequence and is threaded onto the threaded groove. During the installation of electrical components such as circuit breakers inside the electrical box, the base 1 can be externally mounted on the circuit breaker body 2. During the connection process, the bolt structure is inserted through the slotted hole 7 into the positioning hole 8 and finally screwed in. The screw block 5 can be fixed to the pre-reserved screw groove in the device body 2. Then, it can be slidably inserted into the pre-set guide rail in the electrical box through the track groove 3 on the base 1. During the wiring process, when the upper space of the device body 2 is insufficient, the device body 2 can be adjusted up and down on the base 1 by adjusting component 4, thereby increasing the upper wiring space of the device body 2. When the lower space of the device body 2 is insufficient, the device body 2 can be adjusted up on the base 1 by adjusting component 4, thereby increasing the lower wiring space of the device body 2.

[0030] The device body 2 has symmetrically arranged plug ports 11 at both ends. Each plug port 11 has a corresponding threaded cap 10. When wiring, the wire end is inserted into the plug port 11, and then the cap 10 is rotated by a tool. Under the thread engagement action between the cap 10 and the plug port 11, the wire end is pressed tightly into the device body 2 to complete the wiring operation.

[0031] The threaded clamping mechanism between the plug 11 and the cap 10 ensures a secure connection at the wire end and prevents poor contact. At the same time, the adjusting component 4 maintains a stable position during the lifting process through the self-locking characteristic of the screw, avoiding accidental displacement.

The gear teeth of the driving wheel 404 and the driven wheel 405 mesh and are both located inside the isolation cover 401. When the adjustment component 4 is working, the operator manually rotates the rotating cap 402, which drives the driving wheel 404 to rotate. Through the gear tooth meshing action between the driving wheel 404 and the driven wheel 405, the screw 6 is driven to rotate. Under the principle of the lead screw, the rotation action of the screw 6 is transformed into the lifting action of the device 2 on the base 1.
