Description

Technical Field

[0001] This utility model relates to the field of power distribution box technology, and in particular to a power distribution box that is protected against electric shock. Background Technology

[0002] Distribution boxes are used in situations where the loads are relatively dispersed and there are few circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Currently, when inspecting components inside the power distribution box, it is often necessary to disconnect the power beforehand to prevent operators from getting electric shocks. However, there are still cases of operators getting electric shocks because they forget to disconnect the power, which seriously endangers their personal safety. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a power distribution box that is protected against electric shock. It overcomes the shortcomings of the prior art and effectively solves the problem that electric shock still occurs due to operators forgetting to turn off the power, which seriously endangers the personal safety of operators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric shock resistant distribution box includes a box body with a door hinged to the front of the box body. A locking mechanism is connected between the door and an inner wall of one side of the box body. The locking mechanism includes a switch, an arc-shaped shell fixed to the inner wall of one side of the box body, a rotating disk rotatably connected to the door, a connecting rod inserted into the rotating disk, a handle fixed to one end of the connecting rod, a movable rod fixed to the other end of the connecting rod, a fixed rod fixed to one end of the outer wall of one side of the movable rod, a U-shaped block fixed to one end of the fixed rod, and a T-shaped block fixed to the other end of the movable rod.

[0007] The operator rotates the handle by gripping it. The handle, through a connecting rod, drives the movable rod to rotate, which in turn drives the rotating disk, fixed rod, and U-shaped block to rotate. This disconnects the switch handle. The handle, through the connecting rod, moves the movable rod away from the arc-shaped shell, causing the T-shaped block to detach from the arc-shaped shell and the U-shaped block to detach from the switch handle. This allows the door to be opened while simultaneously cutting off power to the box.

[0008] Preferably, mounting plates are fixed on both sides of the back of the switch, and the mounting plates are connected and fixed to one side of the inner wall of the enclosure.

[0009] The switch is installed and fixed to the enclosure using the mounting plate.

[0010] Preferably, the rotation center of the electric gate handle and the center of the rotating disk are located on the same horizontal axis, and the U-shaped block and the electric gate handle form a plug-in fit.

[0011] Rotate the rotating disc and use the U-shaped block to open and close the switch handle.

[0012] Preferably, the front side of the rotating disk is provided with a sliding groove, and the sliding groove and the connecting rod are in sliding fit.

[0013] The connecting rod moves along the slide groove, which in turn drives the movable rod to move.

[0014] Preferably, the back of the rotating disk is provided with a T-shaped groove, and the T-shaped groove forms a sliding fit with the movable rod.

[0015] The movable rod moves along the T-slot to prevent it from detaching from the back of the rotating disk.

[0016] Preferably, the arc-shaped shell has an opening at the top of its arc-shaped outer wall near the rotating disk, and the opening is inserted into the T-shaped block.

[0017] The T-shaped block is inserted into the arc-shaped shell through the opening.

[0018] The beneficial effects of this utility model are as follows:

[0019] The operator rotates the handle, causing the movable rod to rotate the rotating disk, fixed rod, and U-shaped block, thereby disconnecting the switch handle. The handle, through the connecting rod, moves the movable rod away from the arc-shaped shell, causing the T-shaped block to detach from the arc-shaped shell and the U-shaped block to detach from the switch handle. This allows the door to be opened while simultaneously cutting off power to the box, effectively solving the problem of electric shock caused by operators forgetting to disconnect the power, which seriously endangers the personal safety of operators.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example:

[0026] Reference Figure 1-3 An electric shock-proof distribution box includes a box body 1, a door 2 hinged to the front of the box body 1, and a locking mechanism 3 connected between the door 2 and the inner wall of one side of the box body 1. The locking mechanism 3 includes a switch 4, an arc-shaped shell 6 fixed to the inner wall of one side of the box body 1, a rotating disk 7 rotatably connected to the door 2, a connecting rod 8 inserted into the rotating disk 7, a handle 9 fixed to one end of the connecting rod 8, a movable rod 10 fixed to the other end of the connecting rod 8, a fixed rod 11 fixed to one end of the outer wall of one side of the movable rod 10, a U-shaped block 12 fixed to one end of the fixed rod 11, and a T-shaped block 13 fixed to the other end of the movable rod 10.

[0027] Mounting plates 5 are fixed on both sides of the back of the switch 4. The mounting plates 5 are connected and fixed to the inner wall of one side of the housing 1. The switch 4 is installed and fixed to the housing 1 through the mounting plates 5. The rotation center of the switch 4 handle and the center of the rotating disk 7 are located on the same horizontal axis. The U-shaped block 12 is inserted into the switch 4 handle. The rotating disk 7 is rotated, and the U-shaped block 12 is used to open and close the switch 4 handle.

[0028] The front of the rotating disk 7 has a sliding groove, which is slidably engaged with the connecting rod 8. The connecting rod 8 moves along the sliding groove, thereby driving the movable rod 10 to move. The back of the rotating disk 7 has a T-shaped groove, which is slidably engaged with the movable rod 10. The movable rod 10 moves along the T-shaped groove to prevent it from detaching from the back of the rotating disk 7. The top of the arc-shaped shell 6 near the arc-shaped outer wall of the rotating disk 7 has an opening, which is inserted into the T-shaped block 13. The T-shaped block 13 is inserted into the arc-shaped shell 6 through the opening.

[0029] Working principle:

[0030] During operation, the operator rotates the handle 9 by gripping it. The handle 9 drives the movable rod 10 to rotate via the connecting rod 8. The movable rod 10 drives the rotating disk 7, the fixed rod 11, and the U-shaped block 12 to rotate, thereby disconnecting the handle of the power switch 4. The handle 9 also drives the movable rod 10 to move away from the arc-shaped shell 6 via the connecting rod 8, causing the T-shaped block 13 to disengage from the arc-shaped shell 6 and the U-shaped block 12 to disengage from the handle of the power switch 4. This allows the door 2 to be opened while simultaneously cutting off the power inside the box 1.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
