[0002] As the name implies, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. The low voltage distribution cabinets are then led to the distribution boards, control boxes and switch boxes of various power users. The equipment in the distribution device is a combination of switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices that are assembled into one to meet the design functional requirements.

[0003] When the existing high and low voltage distribution box is closed, it is necessary to use a key to open the door lock and flip the protective plate from one side of the distribution box to open it so as to inspect the distribution box. When the key is lost, the door lock cannot be opened. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a high and low voltage distribution box that is easy to maintain, which solves the problem that when the key of the existing high and low voltage distribution box is lost, the door lock cannot be opened and the protective plate cannot be opened from the surface of the distribution box, making it inconvenient to maintain the distribution box.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high and low voltage distribution box that is easy to maintain, including a distribution box body, a base is fixedly installed at the bottom of the distribution box body, and a protective plate is provided on the top of the base, L-shaped clips are symmetrically fixedly installed on both sides of the protective plate, and concave frames are symmetrically fixedly installed on both sides of the distribution box body on the protective plate, three groups of fixing rods are equidistantly fixedly installed on one side of the concave frame, and fixed clips are slidably installed on one end surface of the three groups of fixing rods, and a fixing spring is provided on the surface of the fixing rod located between the concave frame and the fixed clip.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a high and low voltage distribution box that is easy to maintain, including a distribution box body 1, a base 2 is fixedly installed at the bottom of the distribution box body 1, the base 2 includes a bottom plate 201, two groups of rubber convex strips 202 are fixedly installed on one side of the top of the bottom plate 201, and the rubber convex strips 202 are in contact with the protective plate 3. Due to the provision of the rubber convex strips 202, when the protective plate 3 moves on the top of the bottom plate 201, the rubber convex strips 202 rub against the surface of the protective plate 3, ensuring that the protective plate 3 will not move and slide out of the top of the bottom plate 201 at will.

[0020] Side panels 203 are symmetrically fixedly installed on both sides of the bottom plate 201, and a slide groove 204 is provided on the top of the side panel 203. A protective plate 3 is slidably installed between the two groups of slide grooves 204. The slide groove 204 ensures that the protective plate 3 will not tilt or deflect when sliding between the two groups of side panels 203, and at the same time limits the moving range of the protective plate 3.

[0021] Two groups of fixing plates 4 are symmetrically fixed on the top of one side of the protective plate 3, and a mounting rod 401 is fixedly installed between the two groups of fixing plates 4. A roller 402 is rotatably installed on the surface of the mounting rod 401. By providing the roller 402, the roller 402 is close to the ground when the protective plate 3 is parallel to the ground, ensuring that the end of the protective plate 3 away from the bottom plate 201 will not tilt and fall and contact the ground, thereby avoiding damage caused by friction between the protective plate 3 and the ground when the protective plate 3 is pushed.

[0022] L-shaped clips 301 are symmetrically fixedly installed on both sides of the protective plate 3, and concave frames 5 are symmetrically fixedly installed on both sides of the distribution box main body 1 located on the protective plate 3. Three groups of fixed rods 501 are equidistantly fixedly installed on one side of the concave frame 5, and fixed clips 502 are slidably installed on one end surface of the three groups of fixed rods 501. The fixed clips 502 are T-shaped, and the fixed clips 502 correspond to the L-shaped clips 301. One side of the fixed clips 502 is higher than the L-shaped clips 301. Because the L-shaped clips 301 and the fixed clips 502 are provided, when the fixed clips 502 are inserted into the gap between the L-shaped clips 301 and the protective plate 3, it is convenient to fix the protective plate 3 and the distribution box main body 1.

[0023] A fixing spring 503 is provided on the surface of the fixing rod 501 between the concave frame 5 and the fixing clip 502. Due to the fixing spring 503, the fixing clip 502 is pushed toward the L-shaped clip 301 under the elastic action of the fixing spring 503, thereby clamping and fixing the protective plate 3.

[0024] A fixing stud 504 is fixedly installed on one side of the concave frame 5 between two groups of adjacent fixing rods 501, and the fixing stud 504 passes through the fixing clip 502 and is fixedly connected to the distribution box body 1. A fixing screw sleeve 505 is provided on the surface of the fixing stud 504 located between the concave frame 5 and the fixing clip 502. By providing the fixing screw sleeve 505, after the fixing clip 502 is inserted into the gap between the L-shaped clip 301 and the protective plate 3, the fixing screw sleeve 505 is tightened to ensure that the fixing clip 502 clamps and fixes the protective plate 3.

[0025] The working principle of the utility model is:

[0026] Push the fixed clamping strips 502 away from each other, rotate the protective plate 3 to cover the surface of the distribution box body 1, until the L-shaped clamping strip 301 corresponds to the fixed clamping strip 502, loosen the fixed clamping strip 502, and under the elastic action of the fixing spring 503, the fixed clamping strip 502 is clamped between the L-shaped clamping strip 301 and the protective plate 3, and the protective plate 3 is clamped and fixed, and the fixing screw sleeve 505 is tightened to fix the fixed clamping strip 502, ensuring that the protective plate 3 covers one side of the distribution box body 1 and does not tilt and detach;

[0027] When inspecting the distribution box body 1, loosen the fixing screw sleeve 505, push the fixing clip 502 to both sides to make the fixing clip 502 disengage from the L-shaped clip 301, control the protective plate 3 to flip on one side of the distribution box body 1 until the protective plate 3 is parallel to the ground, and the roller 402 is close to the ground, pushing the protective plate 3 to slide between the two sets of side plates 203, and push the protective plate 3 to the top of the bottom plate 201, and fix the protective plate 3 under the friction of the rubber convex strip 202, so as to inspect the distribution box body 1.
