[0025] As shown in the figure, a circuit breaker face mask includes an inverted L-shaped first mask body 1 and a second mask body 2. The front panel of the second mask body 2 can move along the length direction of the front panel of the first mask body 1. The side panel of the first mask body 1 is located on the side away from the second mask body 2, and the side panel of the second mask body 2 is located on the side away from the first mask body 1. An opening and closing door is jointly connected to the front panels of the first mask body 1 and the second mask body 2. The opening and closing door includes a first opening and closing plate 3 and a second opening and closing plate 4 that can move along the length direction of the first opening and closing plate 3. A first U-shaped groove 101 with an opening facing the second mask body 2 is provided on the front panel of the first mask body 1. A second U-shaped groove 201 with an opening facing the first mask body 1 is provided on the front panel of the second mask body 2. The first opening and closing plate 3 is installed in the first U-shaped groove, and the second opening and closing plate 4 is installed in the second U-shaped groove. In this embodiment, the circuit breaker face mask is set in the form of splicing and telescoping of the first mask body 1 and the second mask body 2, making it more suitable for circuit breakers of various specifications. A telescopic opening and closing door is provided on the front side panels of the first mask body 1 and the second mask body 2 and is used in cooperation with the telescoping between the first mask body 1 and the second mask body 2. After the circuit breaker face mask is installed on the circuit breaker, only the opening and closing door needs to be opened to operate the switch body on the circuit breaker. The circuit breaker is protected by the circuit breaker face mask to avoid accidental touch.

[0026] A plurality of connecting ears 9 are provided on the outer sides of the side panels of the first mask body 1 and the second mask body 2 for installing screws to fixedly connect the circuit breaker face mask to a wall or other installation surfaces.

The first guiding edges 5 are clamped in the first guiding grooves 102 and can move along the first guiding grooves 102. In this embodiment, the cross-sections of the first guiding grooves 102 and the first guiding edges 5 are both arc-shaped structures, and the centers of the arcs of the arc-shaped structures are both located inside the arc-shaped structures to prevent the first mask body 1 and the second mask body 2 from separating front and back.

[0028] Two horizontally arranged second guiding edges 6 are symmetrically provided on the front side of the second opening and closing plate 4. Second guiding grooves 301 are provided on the rear side of the first opening and closing plate 3 corresponding to the second guiding edges 6. The second guiding edges 6 are clamped in the second guiding grooves 301 and can move along the second guiding grooves 301. In this embodiment, the cross-sections of the second guiding grooves 301 and the second guiding edges 6 are also arc-shaped structures, and the centers of the arcs of the arc-shaped structures are both located inside the arc-shaped structures to prevent the first opening and closing plate 3 and the second opening and closing plate 4 from separating.

[0029] One end of the first opening / closing plate 3 away from the second housing 2 is hinged in the first C-shaped groove 101. A limiting through groove 401 is provided at the edge of the end of the rear side of the second opening / closing plate 4 away from the second housing 2. A positioning convex edge 202 integrally formed with the second housing 2 is fixedly connected in the second C-shaped groove 201 corresponding to the limiting through groove 401. When the second opening / closing plate 4 is closed in the second C-shaped groove, the positioning convex edge 202 abuts in the limiting through groove 401 to ensure that the second opening / closing plate 4 will not be pushed excessively into the rear side of the second housing 2.

[0030] One end of the front side of the second opening / closing plate 4 away from the first housing 1 is rotatably connected with a limiting block 8. An L-shaped overlapping block 7 is fixedly connected forward on the second housing 2 at the outer side of the second C-shaped groove 201, and the vertical section of the overlapping block 7 is away from the second housing 2 and arranged upward. The limiting block 8 can be overlapped in the overlapping block 7. In this embodiment, the limiting block 8 is also of an L-shaped structure, and the end of the horizontal section is rotatably connected to the edge of the second opening / closing plate 4, and the horizontal section is overlapped in the overlapping block 7. When the opening / closing door needs to be opened, the limiting block 8 can be turned away from the upper side of the overlapping block 7.

[0031] L-shaped first limiting edges 103 are provided at both the top and bottom of the first housing 1, and L-shaped second limiting edges 203 are provided at both the top and bottom of the second housing 2, and the horizontal section of the second limiting edge 203 is located at the rear side of the horizontal section of the first limiting edge 103. In this embodiment, the first limiting edge 103 and the second limiting edge 203 are provided to shield and protect the connection part of the power cord and the circuit breaker.

[0032] Heat dissipation holes 10 are provided on the side panels of the first housing 1 and the second housing 2.

[0033] The working process of this embodiment is as follows:

[0034] Insert the first housing 1 and the second housing 2 together, adjust the insertion length of the first housing 1 and the second housing 2 according to the width dimension of the circuit breaker, and adjust the telescopic length of the opening / closing door; then buckle the circuit breaker face mask on the outside of the circuit breaker and connect it to the wall through screws. When the opening / closing door needs to be opened, turn the limiting block 8 away from the upper side of the overlapping block 7, and then operate the switch body on the circuit breaker.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
