Description

Technical Field

[0001] The utility model belongs to the technical field of electric boxes, and more specifically, it particularly relates to a prefabricated assembly construction structure for the integration of the connection between the base of an electric box and the incoming and outgoing line bridge. Background Technique

[0002] For an electric box protection switch device, that is, except for the installation surface, all sides enclose a low-voltage switch. Electrical system components such as switches, protection, and monitoring in this cabinet are installed in a closed shell that can be made of steel or insulating structural materials. There can be no isolation measures between each circuit in the cabinet, or a grounding metal plate or insulating plate can also be used for isolation. The existing prefabricated assembly construction structure for the integration of the connection between the base of an electric box and the incoming and outgoing line bridge has the following problems. First, for on-site box body punching and bolt connection punching, there are safety hazards for operating workers. Cutting iron filings fly into the box, which not only causes waste of labor costs for cleaning inside the box before power transmission later, but also the sharp edges and burrs of the holes are easy to cut the wires, leading to leakage or short-circuit accidents. Second, using 20# channel steel to make the base wastes steel. The weight of the support base is relatively heavy, which is not conducive to handling and reduces the installation efficiency. Using 5# angle steel welded into the support base, the bottom of the support is hollow, and the quality and appearance are poor. Using iron sheets or fireproof boards to enclose around the angle steel support base is laborious, and the quality is difficult to guarantee. The grounding welding of the base requires frequent use of a welding machine, which is not conducive to safety management. Therefore, a prefabricated assembly construction structure for the integration of the connection between the base of an electric box and the incoming and outgoing line bridge is proposed. Content of the Utility Model

The connection quality between the box and cabinet and the bridge is beautiful and the joints are neat, so as to solve the problems of on-site box body punching and bolt connection punching in the above background technique, where there are safety hazards for operating workers, cutting iron filings fly into the box, which not only causes waste of labor costs for cleaning inside the box before power transmission later, but also the sharp edges and burrs of the holes are easy to cut the wires, leading to leakage or short-circuit accidents.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: an integrated prefabricated assembly construction structure for connecting the electric box base and the incoming and outgoing line bridge frames, including a box body and a panel. The box body and the panel are hinged to each other. Multiple prefabricated incoming line knockout holes are opened in the middle of the top surface of the box body. Multiple first prefabricated holes are also opened on the top surface of the box body. Two incoming and outgoing line bridge frames are also provided on the top surface of the box body. Multiple second prefabricated holes are opened on the outer sides of the two incoming and outgoing line bridge frames.

Multiple third prefabricated holes are opened on the outer sides of the two connecting pieces. The positions of the multiple third prefabricated holes correspond to the positions of the first prefabricated holes and the second prefabricated holes respectively. The two connecting pieces and the box body are fixedly connected by screws.

[0005] As a preferred technical solution of the utility model, a frame body is provided below the box body. The length of the frame body is the same as the length of the box body, and the width of the frame body is the same as the width of the box body. The frame body is made of steel material.

[0007] As a preferred technical solution of the utility model, two connecting plates are fixed to the inner top of the frame body. Two fourth prefabricated holes are opened on the outer sides of the two connecting plates.

[0008] As a preferred technical solution of the utility model, multiple fifth prefabricated holes are opened on the bottom surface of the box body. The positions of the fifth prefabricated holes correspond to the positions of the fourth prefabricated holes. The connecting plates and the box body are fixedly connected by screws. A bottom plate is fixed to the outer bottom of the frame body. Multiple sixth prefabricated holes are opened on the outer side of the bottom plate.

[0009] As a preferred technical solution of the utility model, two guide rods are fixed to the inner top of the box body. A first clamping plate and a second clamping plate are slidably connected between the two guide rods. The first clamping plate and the second clamping plate are both made of plastic material.

[0010] As a preferred technical solution of the utility model, both the first clamping plate and the second clamping plate are in an arc-shaped structure. The first clamping plate and the second clamping plate are arranged in an opposite structure. Two first springs and two second springs are respectively fixed to the opposite sides of the first clamping plate and the second clamping plate.

It effectively avoids inconsistent processes and poor appearance, and eliminates the need for later edge wrapping and closing work. It solves the problems of using 20# channel steel as the base, wasting steel, the heavy weight of the support base being unfavorable for handling, reducing the installation efficiency, using 5# angle steel welded into the support base with the bottom of the support being hollow, resulting in poor quality and appearance, using iron sheets or fireproof boards to enclose around the angle steel support base being labor-consuming, and it is difficult to guarantee the quality, and the frequent use of welding machines for grounding welding of the base being unfavorable for safety management.

[0014] 3. In the prefabricated and assembled construction structure for the connection between the electric box base and the incoming and outgoing cable trays, the first clamping plate and the second clamping plate clamp the cable under the action of the first spring and the second spring respectively, thereby positioning the cable. Since both the first clamping plate and the second clamping plate are arc-shaped structures, the first clamping plate and the second clamping plate intersect with each other to form an enclosed space, making the fixation more secure.
