Description

Technical Field

[0002] Electrical equipment refers to various devices used for the production, transformation, transmission, distribution, and use of electrical energy. They are widely used in industry, commerce, and households, covering the entire power system from power generation to consumption. Electrical equipment typically utilizes distribution boxes. Distribution boxes can house multiple meters simultaneously and are used for distributing electrical energy, protecting circuits, and facilitating circuit opening and closing. They are usually assembled from switchgear, measuring instruments, protective devices, and auxiliary equipment in enclosed or semi-enclosed metal cabinets or panels, forming a low-voltage power distribution system.

[0003] Existing distribution boxes are generally equipped with grounding structures. When the insulation of the equipment inside the distribution box is damaged or there is a leakage, grounding can greatly reduce the voltage to ground of the metal casing, thereby reducing the risk of electric shock. However, existing distribution boxes do not have leakage alarm structures for protection, which may cause leakage accidents to continue to occur undetected, increasing the risk of electric shock and fire. At the same time, when the distribution box is leaking current, people may be electrocuted without alarm warning, which may even endanger their lives in severe cases. Utility Model Content

[0029] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the buffer 107 includes a first rotating seat 107a, a first rotating shaft 107b, a damping rod 107c, and a damping sleeve 107d.

[0034] Specifically, the locking component 108 includes a slot 108a, a spring 108b, and a moving block 108c. The slot 108a is opened inside the door 104, the spring 108b is fixed inside the slot 108a, and the moving block 108c is fixed to one end of the spring 108b.

[0035] The slot 108a allows the spring 108b to extend and retract within it. The extension and retraction of the spring 108b can drive the moving block 108c to move. The movement of the moving block 108c can drive the slide rod 108d and the limit rod 108g to move.

[0036] Specifically, the locking component 108 also includes a slide rod 108d and a push ball 108e. The slide rod 108d is fixed to the bottom of the moving block 108c and is slidably connected to the inner wall of the door 104. The push ball 108e is fixed to the bottom end of the slide rod 108d.

[0037] The slide bar 108d is used to connect the push ball 108e and the moving block 108c, and the push ball 108e is used to push the slide bar 108d to move.

[0038] Specifically, the locking component 108 also includes a limiting groove 108f and a limiting rod 108g. The limiting groove 108f is formed on the inner wall of the empty groove 108a, the limiting rod 108g is slidably connected to the inner wall of the limiting groove 108f, and the limiting rod 108g is fixed to the outside of the moving block 108c.

[0039] The sliding of the limiting rod 108g within the limiting groove 108f can improve the stability of the movement of the moving block 108c.

[0040] Specifically, the locking component 108 also includes a locking rod 108h and a moving groove 108i. The locking rod 108h is fixed to the outside of the moving block 108c, and the moving groove 108i is opened on the inner wall of the door 104. The locking rod 108h is slidably connected to the inner wall of the moving groove 108i.

[0041] The lever 108h can move within the moving slot 108i, improving the stability of the lever 108h's movement.

[0042] Specifically, the locking component 108 also includes a locking ball 108j and a locking groove 108k. The locking ball 108j is fixed to one end of the locking rod 108h, and the locking groove 108k is opened in the inner wall of the distribution box 101. The locking ball 108j is locked into the inner wall of the locking groove 108k.

[0043] The ball 108j is inserted into the slot 108k, which facilitates the locking and fixing of the box door 104 and the distribution box 101. Example 3

[0044] Reference Figure 1 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the grounding component 205 includes a grounding wire 205a and a locking pin 205b. The grounding wire 205a is fixed to the inner wall of the distribution box 101, and the locking pin 205b is fixed to the outside of the grounding wire 205a.

[0046] The grounding wire 205a can be connected to the grounding terminal and the locking pin 205b installed in the distribution box 101. The locking pin 205b can be inserted into the sleeve 205c.

[0047] Specifically, the grounding component 205 also includes a sleeve 205c, a discharge post 205d, a cone 205e, and a slot 205f. The sleeve 205c is fitted onto the outside of the locking pin 205b, the discharge post 205d is fixed to the bottom of the sleeve 205c, the cone 205e is fixed to the bottom of the discharge post 205d, and the slot 205f is opened on the outside of the discharge post 205d.

[0048] The sleeve 205c allows workers to use a hammer to strike the cone 205e, causing it to move downwards. The discharge column 205d can transmit the electrical charge generated by leakage to the ground. The cone 205e can be inserted into the ground. The notch 205f can improve the effect of the cone 205e when it is inserted into the ground.

[0049] In use, the worker strikes the sleeve 205c with a hammer to lower the cone 205e into the ground until the top of the sleeve 205c is flush with the ground. Then, the locking pin 205b, connected to the grounding wire 205a, is inserted into the sleeve 205c, ensuring contact between the locking pin 205b and the inside of the sleeve 205c. This ensures that the distribution box 101 is grounded, improving its safety. When using the distribution box 101, the meter 102 inside can be controlled by opening the box door 104. Opening the box door 104 pushes the push ball 108e, causing the slide rod 108d to move upwards. The movement of the slide rod 108d then moves the moving block 108c upwards. The moving block 108c moves to compress the spring 108b, which in turn moves the locking rod 108h. The movement of the locking rod 108h causes the locking ball 108j to move within the locking slot 108k, thus pulling the locking ball 108j out of the locking slot 108k and opening the box door 104. At the same time, the box door 104 pulls the damping rod 107c to slide within the damping sleeve 107d. When a leakage occurs in the distribution box 101, the leakage protector 201 detects the leakage and transmits a signal to the outer casing 202, triggering the sound outlet 203 and the warning light 204 to provide an alarm. The electrical charge generated by the leakage in the distribution box 101 is transmitted to the ground through the grounding wire 205a.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
