Description
Technical Field
[0001] The utility model relates to a distribution box, in particular to a double-layer protection type switch box. Background Art
[0002] The power distribution system at the construction site should be equipped with a main distribution box, a distribution box, and a switch box, and they should be set up in a hierarchical manner in the order of "main-sub-open" to form a "three-level distribution" mode. According to the requirements of the specification of "one machine, one switch, one leakage, and one box", each electrical equipment at the construction site should be equipped with a special switch box. In actual use, due to the large number of electrical equipment at the construction site, a large number of switch boxes are required. However, due to the poor safety awareness of the workers at the construction site, non-professional electricians have repeatedly violated the regulations and privately repaired the wiring. The problem of one switch in the switch box for multiple machines and private wiring has been repeatedly banned.
[0003] Therefore, a technical solution is currently needed to solve the technical problem that the existing switch box cannot prevent non-professional electricians at the construction site from performing wiring operations inside the switch box. Utility Model Content
[0004] The invention purpose of the utility model is to provide a double-layer protection switch box to solve the technical problem in the prior art that the switch box cannot prevent non-professional electricians on the construction site from performing wiring operations inside the switch box.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A double-layer protective switch box includes a box body, an opening is provided on one side of the box body, a circuit switch is provided in the box body, a first protective door and a second protective door are provided at the opening, the first protective door and the second protective door are stacked, the second protective door is provided on a side of the first protective door away from the box body, and an operation window corresponding to the position of the circuit switch is provided on the first protective door.
[0007] The utility model discloses a double-layer protection switch box. When in use, electrical components and circuit switches are installed inside the box. A first protection door and a second protection door both seal the inner space of the box at the opening. When the second protection door is opened, the circuit switch in the box can be operated through the operation window on the first protection door. When the first protection door and the second protection door are opened, the electrical components in the box can be operated. In this way, in the absence of a key to the first protection door lock, ordinary operators can only open and close the circuit switch, thereby avoiding the need for ordinary operators to perform wiring operations on the switch box, thereby avoiding the phenomenon of one switch for multiple machines and private connection.
[0008] As a preferred solution of the utility model, the box body includes a left side plate, a right side plate, a rear side plate, a bottom plate and a top plate, and the left side plate, the right side plate, the rear side plate, the bottom plate and the top plate are enclosed to form a box body structure with an opening on one side. The box body is enclosed by the left side plate, the right side plate, the rear side plate, the bottom plate and the top plate to form a rectangular box body, which has a simple structure and is easy to process, thereby reducing the manufacturing cost of the box body. At the same time, the box body has little interference with the operation of the operator, and the installation of various electrical components in the box body is relatively simple.
[0009] As a preferred solution of the utility model, it also includes a support frame, which includes two frames arranged opposite to each other, the two frames are respectively connected to the bottom sides of the bottom plate, and the frame includes two legs, and a reinforcing rod is connected between the two legs. The support frame can support the box body to a position away from the ground, so as to avoid the box body from being damp due to long-term contact with the ground, and at the same time, it can also reduce dust from entering the box body, thereby protecting the electrical components in the box body.
[0010] As a preferred solution of the utility model, the two frames are arranged in an eight-shaped shape at the bottom of the box body, thereby improving the supporting capacity of the support frame to the box body, making the box body more stable when placed on the ground and not prone to tipping or displacement due to external forces.
[0011] As a preferred solution of the utility model, a drainage slope is provided on the top of the top plate, and the edge of the top plate extends out of the side of the box body. In the case of outdoor operation, the drainage slope can lead rainwater to the surrounding of the box body for discharge, avoiding the problem of rainwater entering the box body and causing corrosion of the electrical components inside the box body.
[0012] As a preferred solution of the utility model, the bottom plate is provided with a wiring hole connected to the internal space of the box. By providing the wiring hole at the bottom of the box, the external circuit is connected to the electrical components inside the box, which can prevent the collision of surrounding people or other objects with the external circuit, causing unstable wiring.
[0013] As a preferred solution of the utility model, an insulating rubber ring is arranged around the inner wall of the wiring hole. The insulating rubber ring has a protective effect on the external circuits entering and exiting the box body, and reduces the wear of the circuits at the wiring hole.
[0014] As a preferred solution of the utility model, an insulating plate is provided inside the rear side plate, and the insulating plate is used to install electrical components, thereby regulating the arrangement of electrical components in the box and reducing leakage accidents caused by aging of circuits or components.
[0015] As a preferred solution of the utility model, a braided soft copper wire is connected between the second protection door and the box body, so that the box body and the second protection door maintain the same potential, avoiding the second protection door from being charged, and playing a role in protecting the operating personnel.
[0016] As a preferred solution of the utility model, the inner wall of the second protective door and the inner wall of the box are both provided with studs, and the studs are sleeved with clamping nuts, and collars are respectively provided at both ends of the braided soft copper wire, and the collars are used to be sleeved on the studs, and the clamping nuts are used to press the collars onto the inner wall of the second protective door or onto the inner wall of the box. Since the second protective door needs to be opened and closed frequently, the braided soft copper wire is frequently pulled under the drive of the second protective door, and is prone to breakage and wear. In this solution, studs are respectively provided on the inner wall of the box and the inner wall of the second protective door, so that the two ends of the braided soft copper wire are detachably connected to the box and the second protective door, respectively, so that it is convenient to replace the braided soft copper wire after it is damaged, and the structure is simple and easy to operate.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0018] The present application sets two layers of protective doors on the switch box, so that ordinary operators can only open the second protective door and perform the opening and closing operations of the circuit switch at the operating window of the first protective door, thereby avoiding ordinary operators from performing wiring operations on the switch box, thereby avoiding the phenomenon of one switch for multiple machines and private wiring.
