Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with a protection function. Background Art
[0002] The distribution box is the most commonly used accessory in the power system. The electronic components are combined and fixed inside the cabinet. After power is turned on, the power system can complete the work through system calculations.
[0003] According to observations based on existing technologies, power distribution cabinets use multiple layers of protection during use, which increases the weight of the power distribution cabinet. More protection will also lead to reduced heat dissipation capacity of the power distribution cabinet, thereby reducing the service life of electronic components. Moreover, when the power distribution cabinet is powered on, it is impossible to effectively determine whether there is a leakage phenomenon. If a worker is electric shocked without knowing it, this will not only damage the electronic components in the distribution box, causing equipment short circuits and problems with the power supply system, but more importantly, it may threaten the life safety of the worker.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0023] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.
[0024] A distribution box with a protection function provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.
[0025] Combination Figure 1-4 As shown, the utility model provides a distribution box with a protection function, comprising a cabinet 1, a side wall of the cabinet 1 is fixedly connected with a rotating shaft 2, one side of the rotating shaft 2 is fixedly connected with a door panel 3, one side of the door panel 3 is rotatably connected with a handle 4, one side of the door panel 3 is slidably connected with a lock block 28, one end of the lock block 28 is provided with a moving block 5, one side of the moving block 5 is fixedly connected with a first spring 6, one side of the moving block 5 is fixedly connected with an active rack 7, the side of the active rack 7 is meshedly connected with a transmission gear 8, one side of the transmission gear 8 is meshedly connected with a driven rack 9, one side of the driven rack 9 is fixedly connected with a sliding rod 10, and one end of the sliding rod 10 is fixedly connected with a power-on block 12;
[0026] One end of the power-on block 12 is slidably connected to a protection strip 15 in a through-shape, one side of the protection strip 15 is fixedly connected to a connection block 16, the bottom of the connection block 16 is fixedly connected to a wire tube 17, and one end of the locking block 28 is slidably connected to a lock buckle 14 in a through-shape, and the lock buckle 14 is fixedly connected to one end of the connecting strip 13.
[0027] In the first embodiment, when the door panel 3 is opened, the handle 4 is rotated to drive the lock block 28 to leave the moving block 5. The moving block 5 is driven to return to its original position under the action of the first spring 6. When returning to its original position, the active rack 7 is driven to engage with the transmission gear 8, and after engagement, the driven rack 9 is driven to engage, and then the sliding rod 10 is driven to move, so that the power-on block 12 on the sliding rod 10 leaves the power-on parts in the protection strip 15, so that the cabinet 1 can be powered off. After the power is off, the staff can work normally, and after the current through the wire tube 17 and the power-on board 18 is disconnected, the equipment can be powered normally. This is the first protection system.
[0028] A power-carrying plate 18 is fixedly connected to the bottom of the cabinet 1, and a moving bar 19 is slidably connected to the side of the power-carrying plate 18 in a through-shaped manner. One end of the moving bar 19 is fixedly connected to an extrusion block 22, and a sliding bar 23 is slidably connected to the top of the extrusion block 22. The top of the sliding bar 23 is symmetrically fixedly connected to a third spring 24, and a connecting port 25 is fixedly opened on the top of the sliding bar 23. One end of the connecting port 25 is slidably connected to a power-carrying rod 26 in a through-shaped manner. A placement rack 27 is fixedly connected to the top of the power-carrying rod 26, and the placement rack 27 is fixedly connected to the inner wall of the cabinet 1, a stopper 20 is fixedly connected to one side of the moving bar 19, and a second spring 21 is fixedly connected to one side of the stopper 20, and a support block 11 is fixedly connected to one side of the sliding rod 10, and one end of the support block 11 is fixedly connected to the inner wall of the connecting bar 13.
[0029] In the second embodiment, when the door panel 3 is opened, the second spring 21 will drive the block 20 to reset, and when resetting, it can drive the moving bar 19 to move. When the moving bar 19 moves, it can drive the squeezing block 22 to leave the sliding bar 23. Under the action of the third spring 24, the sliding bar 23 can quickly leave the power-on rod 26, so that the placement rack 27 can be powered off. In the process of power off, if an uninformed person suddenly powers on the cabinet 1, the power-on board 18 and the placement rack 27 will not be powered, and the equipment will not be powered normally, thereby protecting the life safety of the staff during maintenance. This is the second protection system.
[0030] The working principle and use process of the utility model are as follows: when it is necessary to inspect or maintain the parts in the cabinet 1, the lock block 28 will leave the lock buckle 14 when the handle 4 is turned to open the door panel 3, and the moving block 5 will lose the extrusion force at the same time, and the first spring 6 will drive the active rack 7 on the moving block 5 to engage with the transmission gear 8. When the transmission gear 8 is engaged, it will drive the driven rack 9 to move, and then drive the power-on block 12 on the sliding rod 10 to leave the power-on element in the protection strip 15. At the same time, when the door panel 3 is opened, the second spring 21 will drive the moving bar 19 on the block 20 to move. When the moving bar 19 moves, it can drive the extrusion block 22 to leave the sliding bar 23. Under the push of the third spring 24, the sliding bar 23 allows the connecting port 25 to leave the power-on rod 26, thereby cutting off the power to the cabinet 1.
[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
