Description

Technical Field

[0001] The utility model belongs to the technical field of cable branch boxes, and in particular relates to a cable branch box with explosion-proof function. Background Art

[0002] The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer cables. It mainly plays the role of cable branching and cable transfer.

[0003] Since conventional cable branch boxes use conventional fan-shaped doors to close the internal space, the door has only one locking point. When an explosion unfortunately occurs inside, it is difficult to withstand the internal explosion shock wave, resulting in a relatively low explosion-proof coefficient of conventional cable branch boxes.

[0004] To this end, we propose a cable branch box with explosion-proof function to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low explosion-proof coefficient of conventional cable branch boxes and proposes a cable branch box with explosion-proof function.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cable branch box with explosion-proof function, including a box body, an external sliding sleeve of the box body is provided with an explosion-proof cover, the side end of the explosion-proof cover is fixedly connected with an elastic clamp, the inner part of the elastic clamp is provided with a guide column, the guide column is symmetrically arranged on the outer side of the box body, the lower part of the box body is fixedly connected with a binding frame, the lower end of the guide column is fixedly connected with the binding frame, the box body and the binding frame are slidably inserted and matched with a bolt rack, the bolt rack is rotatably installed with a knob, the knob passes through the bolt rack, the rear end of the knob is fixedly connected with a bolt, the bolt is threadedly connected and matched with the binding frame, and the binding frame is matched with the lower sleeve of the explosion-proof cover. Pull the explosion-proof cover downward so that the lower part of the explosion-proof cover is inserted into the inner side of the restraining frame, and then the bolt bracket is passed through the restraining frame, the explosion-proof cover and the box body, and then the bolts are screwed into the restraining frame to keep the bolt bracket on the restraining frame, so that the explosion-proof cover is stabilized outside the box body. When an explosion unfortunately occurs in the box body, the explosion-proof cover is used to hinder the diffusion of the explosion shock wave, and the restraining frame is used to restrain the lower part of the explosion-proof cover, thereby increasing the stability of the lower structure of the explosion-proof cover and improving the explosion-proof capability of the box body.

[0008] Preferably, a tension spring is provided between the elastic clip and the guide column, the tension spring is movably sleeved on the guide column, the upper end of the tension spring is fixedly connected to the guide column, and the lower end of the tension spring is fixedly connected to the elastic clip. The elastic force of the tension spring is used to act upward on the elastic clip, so that the elastic clip acts upward on the explosion-proof cover to overcome the influence of gravity of the explosion-proof cover, thereby reducing the lifting force of the explosion-proof cover.

[0009] Preferably, the box body comprises a box shell and fixed legs, and the fixed legs are symmetrically fixedly connected to the lower end of the box shell. The height of the box shell can be easily raised by the fixed legs.

[0010] Preferably, the restraint frame includes a frame body, a connecting frame and a connecting block, wherein the connecting frame is fixedly connected to the lower inner end of the frame body, and the connecting block is symmetrically fixedly connected to the side end of the frame body. After the explosion-proof cover is closed downward, the frame body is sleeved on the lower part of the explosion-proof cover to stabilize the lower structure of the explosion-proof cover and increase the explosion-proof ability of the lower part of the explosion-proof cover.

[0011] Preferably, the elastic clamp comprises an elastic hoop and a fixing seat, and the fixing seat is fixedly connected with the elastic hoop as a whole. The elastic hoop is clamped on the outer end of the guide column to increase the friction between the elastic clamp and the box body, so as to facilitate the positioning of the explosion-proof cover after it is lowered.

[0012] Preferably, the bolt bracket includes a plug, a slide bar and a connecting rod, the slide bar is symmetrically fixedly connected to the side end of the connecting rod, and the plug is symmetrically fixedly connected to the rear end of the connecting rod. After the explosion-proof cover is closed, the plug is passed through the frame, the explosion-proof cover and the box shell, the operating knob drives the bolt to rotate, the bolt is screwed into the front part of the frame, the bolt bracket is fixed, and the explosion-proof cover is conveniently restrained by the bolt bracket.

[0013] Preferably, the bolt bracket includes a guide block, which is fixedly connected to the rear end of the bolt. The guide block facilitates the insertion of the bolt into the box, the restraining frame and the explosion-proof cover.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Pull the explosion-proof cover downward so that the lower part of the explosion-proof cover is inserted into the inner side of the restraining frame, and then the bolt bracket is passed through the restraining frame, the explosion-proof cover and the box body, and then the bolts are screwed into the restraining frame to keep the bolt bracket on the restraining frame, so that the explosion-proof cover is stabilized outside the box body. When an explosion unfortunately occurs in the box body, the explosion-proof cover is used to hinder the diffusion of the explosion shock wave, and the restraining frame is used to restrain the lower part of the explosion-proof cover, thereby increasing the stability of the lower structure of the explosion-proof cover and improving the explosion-proof capability of the box body.

[0016] 2. Use the elastic force of the tension spring to act upward on the elastic clip, so that the elastic clip acts upward on the explosion-proof cover to overcome the influence of gravity of the explosion-proof cover, thereby reducing the lifting force of the explosion-proof cover.

[0017] 3. After closing the explosion-proof cover downwards, use the frame to cover the lower part of the explosion-proof cover to stabilize the lower structure of the explosion-proof cover and increase the explosion-proof ability of the lower part of the explosion-proof cover.

[0018] 4. Use the elastic clamp to clamp the outer end of the guide column to increase the friction between the elastic clamp and the box body, making it easier to position the explosion-proof cover after it is lowered.

[0019] 5. After closing the explosion-proof cover, insert the bolt through the frame, explosion-proof cover and box shell, operate the knob to drive the bolt to rotate, screw the bolt into the front of the frame, fix the bolt bracket, and use the bolt bracket to facilitate the restraint of the explosion-proof cover.
