[0009] The upper cover is also provided with a guide plate, and the guide plate is provided with a guide ramp; the bottom shell is provided with a guide pin that is arranged opposite to the guide ramp.

[0010] The guide plate has an L-shaped structure.

[0011] The switch assembly includes a guide rail and a switch mounted on the guide rail.

[0012] The upper cover is provided with a rotatable knob, which is used to turn the switch off when rotated.

[0013] It also includes a bracket, which has a rotating plate, and the knob has a rotating shaft that extends into the housing and is linked to the rotating plate.

[0014] The rotating plate is provided with a long groove, and the handle of the switch is provided with a linkage plate, on which a guide rod is provided that cooperates with the long groove.

[0015] The bracket is mounted on the guide rail.

[0016] The beneficial effects of this utility model are: This utility model provides an explosion-proof box with a guiding structure, which can guide when the top cover is closed, making the positioning more accurate. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings. An explosion-proof box with a guiding structure includes a box body 1, a switch assembly 2 inside the box body, and a bottom shell 11 with a conical guide protrusion 111 on its upper surface. A top cover 12 is rotatably connected to the bottom shell, and a guide groove 121 is provided on its lower surface. The guide protrusion is positioned opposite to the guide groove and is located within the guide groove when the box body is closed. The guide protrusion has a conical structure. When the top cover is closed, if there is a slight deviation, the guide groove will fall onto the circumferential outer wall of the guide protrusion (which is inclined). Then, as the top cover is closed further, the outer wall of the guide protrusion will automatically center the guide groove, achieving a positioning function.

[0024] In this embodiment, as shown in the figure, at least two guide protrusions are provided. Preferably, they can be arranged diagonally opposite each other.

[0025] In this embodiment, as shown in the figure, the upper cover is further provided with a guide plate 123, and the guide plate is provided with a guide ramp 124; the bottom shell is provided with a guide pin 112 opposite to the guide ramp. Meanwhile, to further enhance the guiding effect, the guide ramp and guide pin also provide guidance when the upper cover is closed.

[0026] In this embodiment, as shown in the figure, the guide plate has an L-shaped structure. The bottom of the L-shape is provided with the guide ramp, and the top horizontal plate serves as a limit.

[0027] In this embodiment, as shown in the figure, the switch assembly includes a guide rail 21 and a switch 22 mounted on the guide rail. The switch can be a circuit breaker, etc., and how the circuit breaker is mounted on the guide rail is existing technology.

[0028] In this embodiment, as shown in the figure, the upper cover is provided with a rotatable knob 118, which, when rotated, is used to disconnect the switch. This allows for convenient operation of the switch without opening the upper cover.

[0029] In this embodiment, as shown in the figure, a bracket 23 is also included. The bracket is provided with a rotating plate 231, and the knob is provided with a rotating shaft 113. The rotating shaft extends into the housing and is linked to the rotating plate. The switch is turned off by rotating the rotating plate through the rotating shaft.

[0030] In this embodiment, as shown in the figure, the rotating plate is provided with a long slot 232, the switch handle is provided with a linkage plate, and a guide rod 223 that cooperates with the long slot is provided on the linkage plate. The linkage plate is provided with a linkage block 225, and the rotating shaft is provided with a linkage groove 226 to realize linkage connection. The structure is simple and easy to use. The linkage plate is originally provided on the switch and belongs to the prior art. Its purpose is to connect the handles of multiple circuit breakers together.

[0031] In this embodiment, as shown in the figure, the bracket is mounted on the guide rail. Mounting can be achieved using methods such as screw installation.
