DETAILED DESCRIPTION

[0021] Hereinafter, embodiments of the switch for a power distribution cabinet of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 The switch installation structure of a distribution cabinet of an embodiment of the utility model is shown, which includes: a mounting plate 5 in the inner cavity of the distribution cabinet 1 and a clamping block 7 fixedly installed on the rear side of the electric switch 6: the inner cavity of the distribution cabinet 1 is fixedly connected with two symmetrical hanging plates 3, the mounting plate 5 is fixedly connected to the front of the hanging plate 3, the front of the hanging plate 3 is penetrated by a screw 4, the screw 4 is threadedly connected to the distribution cabinet 1, a groove 1 is provided at the bottom of the clamping block 7, a spring 11 is provided in the inner cavity of the groove 1, and a limit arc block 10 is provided at the bottom of the clamping block 7, and the spring 11 is provided in the inner cavity of the groove 1. One end of the spring 11 is welded to the limiting arc block 10, and the other end of the spring 11 is welded to the inner wall of the groove 1. Through the setting of the limiting arc block 10, when replacing the switch, after unlocking, the limiting arc groove 13 will limit the limiting arc block 10, so that the undamaged electric switch 6 will not fall off the inner cavity of the installation groove 8, ensuring the stability of other switches. The top of the card block 7 is fixedly connected with a rack 9, and the bottom of the card block 7 is fixedly connected with a positioning block 12. A plurality of positioning grooves 14 are provided at the bottom of the installation groove 8. The positioning block 1 2 is slidably connected with the positioning groove 14, a limiting arc groove 13 is provided at the bottom of the inner cavity of the installation groove 8, and the limiting arc groove 13 is adapted to the limiting arc block 10. The front of the installation plate 5 is provided with a mounting groove 8, and the top of the inner cavity of the installation groove 8 is provided with a groove 2 17. A sliding rod 16 is provided through the top of the installation plate 5, and a pull block 15 is fixedly connected to the top of the sliding rod 16. Through the setting of the pull block 15, a force point can be provided for pulling the sliding rod 16 later, which is convenient for the user to operate the sliding rod 16, so that the rack 1 9 and the rack 2 19 is disengaged from the card, which facilitates the disassembly between the mounting groove 8 and the card block 7, and provides convenience for the later disassembly of the switch. The slide bar 16 penetrates into the inner cavity of the groove 17 and slides in the inner cavity of the groove 17. The bottom of the slide bar 16 is fixedly connected with a rack 19, and the rack 19 is engaged with the rack 19. The inner cavity of the groove 17 is provided with two symmetrical springs 18. One end of the spring 18 is welded to the top of the inner cavity of the groove 17, and the other end of the spring 18 is welded to the top of the rack 19.

[0023] Working principle: when the utility model is used, the user first takes the electric switch 6, moves the position of the electric switch 6 to insert the card block 7 into the installation groove 8, so that the card block 7 will be stuck in the inner cavity of the mounting plate 5. During the insertion of the card block 7, the plane of the teeth of the rack 1 9 will then abut against the plane of the teeth of the rack 2 19 to ensure that the card block 7 will not shake in the cavity of the installation groove 8, and then the limiting arc groove 13 will limit the limiting arc block 10 at the bottom of the card block 7. At this time, the spring 11 in the inner cavity of the limiting arc block 10 will be deformed by extrusion, so that the limiting arc block 10 at the bottom of the card block 7 will not separate from the inner cavity of the limiting arc groove 13, and then the positioning groove 14 will limit the positioning block 12, and then the positioning groove 14 will stabilize the positioning block 12, avoiding The electric switch 6 is prevented from moving left and right. Finally, when a single switch of the distribution cabinet is damaged, the pull block 15 and the slide rod 16 are pulled upwards, and the rack 19 will slide deep into the inner cavity of the groove 17 and squeeze the spring 18. At this time, the rack 19 and the rack 19 are disengaged, and the user holds the electric switch 6 with his hand and applies force outward, and the clamping block 7 is disengaged from the inner cavity of the mounting groove 8. At this time, the limiting arc block 10 is disengaged from the inner cavity of the limiting arc groove 13, and the positioning block 12 is also disengaged from the inner cavity of the positioning groove 14. At this time, the single damaged electric switch 6 is successfully removed. Subsequently, the limiting arc groove 13 and the positioning groove 14 are set to replace the single electric switch 6, so that the clamping blocks 7 on other electric switches 6 will not be disengaged from the inner cavity of the mounting groove 8 during the process of removing the switch.

[0024] To sum up: the switch installation structure of the distribution cabinet, by picking up the electric switch 6, the block 7 enters the inner cavity of the installation groove 8, so that the rack 2 19 is engaged with the rack 1 9, and the block 7 is fixed in the inner cavity of the mounting plate 5, and the block 7 is positioned by the positioning groove 14 and the positioning block 12, so that the limiting arc block 10 enters the inner cavity of the limiting arc groove 13, so that the electric switch 6 is fixed on the mounting plate 5. When the switch is damaged and needs to be disassembled, the electric switch 6 is held by hand, the engagement between the rack 2 19 and the rack 1 9 is unlocked, and the block 7 on the rear side of the electric switch 6 is separated from the inner cavity of the mounting groove 8, so that the switch can be quickly installed and can be replaced independently when damaged, thereby improving the efficiency of switch maintenance in the distribution cabinet.
