Detailed implementation manners

[0026] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0027] As Figure 1 、 2As shown in FIGS. 3, 5, and 6, in this embodiment, it includes a cabinet body 1 and a base 2. The base 2 is fixed below the cabinet body 1. A support plate 3 is provided inside the base 2. Four corners at the lower end of the support plate 3 are rotatably connected with rollers 5. Through grooves 4 corresponding to the rollers 5 are formed on both sides at the lower end of the base 2. A lifting drive assembly is provided inside the base 2. The lifting drive assembly includes a forward and reverse motor 7, a main gear 9, a lead screw 8, a synchronous gear 10, and a limiting shaft 6. The forward and reverse motor 7 is fixed to the inner top end of the base 2. The main gear 9 is connected to the power end of the forward and reverse motor 7. Two lead screws 8 are provided and are distributed left and right and are rotatably connected inside the base 2. The support plate 3 is threadedly sleeved with the lead screws 8. Two synchronous gears 10 are provided and are fixedly sleeved around the two lead screws 8 one by one. The synchronous gears 10 are both meshed with the main gear 9. Two limiting shafts 6 are provided and are distributed left and right and are fixed inside the base 2. The support plate 3 is slidably sleeved with the limiting shafts 6.

[0028] When it is necessary to move the power supply cabinet, the forward and reverse motor 7 works to drive the main gear 9 to rotate forward. The main gear 9 will drive the two synchronous gears 10 to rotate synchronously. Therefore, the synchronous gears 10 will drive the lead screws 8 to rotate. Then the lead screws 8 will drive the support plate 3 to move downward along the limiting shafts 6, so as to drive the rollers 5 to move out of the through grooves 4 through the support plate 3 until the power supply cabinet is supported by the rollers 5. At this time, the base 2 is separated from the ground. Then, by rotating the rollers 5, the power supply cabinet can be easily and labor - savingly moved, so that the power supply cabinet can be conveniently moved for use.

[0029] As Figure 2 、 3 、5, and 6 show, in this embodiment, it includes a cabinet body 1 and a base 2. The forward and reverse motor 7 is fixed to the inner top end of the base 2. The main gear 9 is connected to the power end of the forward and reverse motor 7. Two lead screws 8 are provided and are distributed left and right and are rotatably connected inside the base 2. The support plate 3 is threadedly sleeved with the lead screws 8. Two synchronous gears 10 are provided and are fixedly sleeved around the two lead screws 8 one by one. The synchronous gears 10 are both meshed with the main gear 9. Two limiting shafts 6 are provided and are distributed left and right and are fixed inside the base 2. The support plate 3 is slidably sleeved with the limiting shafts 6.

[0030] When it is necessary to stably support the power supply cabinet, the forward and reverse motor 7 works to drive the main gear 9 to rotate reversely. The main gear 9 will drive the synchronous gears 10 and the lead screws 8 to rotate synchronously. So the lead screws 8 will drive the support plate 3 to move upward along the limiting shafts 6 to reset until the support plate 3 drives the rollers 5 to be received into the base 2. At this time, the base 2 contacts the ground. Then the base 2 supports the cabinet body 1, which is beneficial to ensuring the stability of the power supply cabinet during support use and effectively avoiding the situation that the power supply cabinet accidentally moves due to the rotation of the rollers 5.

[0031] As shown Figure 2-4 in the figure, in this embodiment, it includes a cabinet body 1 and a base 2. An alarm 18 and a GPS locator 19 are installed inside the base 2. A groove 12 is formed in the middle of the lower end of the base 2. A bottom plate 13 is provided in the groove 12. An installation cavity 11 is formed inside the base 2. The installation cavity 11 corresponds to the groove 12 up and down. A pressing plate 15 is provided inside the installation cavity 11. A pressing rod 14 is fixed to the upper end of the bottom plate 13. The pressing rod 14 slides through the base 2 and penetrates into the installation cavity 11. The pressing plate 15 is fixed to the upper end of the pressing rod 14. A return spring 16 and a touch switch 17 that are connected to the inner bottom end of the installation cavity 11 are provided below the pressing plate 15. The upper end of the return spring 16 is connected to the lower end of the pressing plate 15.

[0032] When the base 2 contacts the ground, on the premise that the bottom plate 13 is received in the groove 12, at this time the bottom plate 13 contacts the ground, that is, the ground pushes the bottom plate 13 upward. Moreover, the pressing plate 15 is set to stretch the return spring 16, and the pressing plate 15 is set to be away from the touch switch 17. Therefore, the touch switch 17 is in an off state. Therefore, on the premise that the touch switch 17 is connected in series with the alarm 18, when the touch switch 17 is off, the alarm 18 does not emit an alarm sound. If an outsider moves the power supply cabinet without permission, it is necessary to separate the base 2 from the ground to move the power supply cabinet. Therefore, when the base 2 is separated from the ground, the return elastic force of the return spring 16 will drive the pressing plate 15, the pressing rod 14 and the bottom plate 13 to move downward, so that the bottom plate 13 moves downward out of the groove 12. At the same time, the pressing plate 15 will press and activate the touch switch 17. Then the touch switch 17 will control the alarm 18 to emit an alarm sound, which is beneficial to reminding outsiders not to move the power supply cabinet without permission, and is beneficial to reminding the surrounding staff to arrive at the scene to stop the movement, so that the power supply cabinet has a certain anti-movement alarm function. Combined with the GPS locator 19 to locate the position of the power supply cabinet, the anti-theft performance of the mobile power supply cabinet is effectively guaranteed.

[0033] As shown Figure 2-4 in the figure, in this embodiment, a first switch receiver 21 close to the forward and reverse motor 7 is installed inside the base 2. The forward and reverse motor 7 is connected in series with the first switch receiver 21. An electromagnet 20 and a second switch receiver 22 are connected to the inner top end of the installation cavity 11. The second switch receiver 22 is connected in series with the electromagnet 20. The pressing plate 15 is made of metal iron. The electromagnet 20 corresponds to the pressing plate 15 up and down. A remote control transmitter 23 is provided outside the cabinet body 1. Both the first switch receiver 21 and the second switch receiver 22 are signal-connected to the remote control transmitter 23.

[0034] When the staff needs to move the power supply cabinet normally, the first switch receiver 21 is controlled to work by operating the remote control transmitter 23. The first switch receiver 21 will control the forward and reverse motor 7. On the premise that the remote control transmitter 23 is placed beside the staff, therefore, outsiders cannot control the lifting drive assembly to move the rollers 5 up and down, so outsiders cannot drive the power supply cabinet to move through the rollers 5, thus preventing outsiders from easily moving the power supply cabinet. And when the staff moves the power supply cabinet normally, in order to prevent the alarm 18 from alarming accidentally, the second switch receiver 22 is controlled to work by the remote control transmitter 23. The second switch receiver 22 will control the electromagnet 20 to be energized and work. At this time, the electromagnet 20 will adsorb upwards the pressing plate 15 made of metal iron. At the same time, the pressing plate 15 will drive the pressure rod 14 and the bottom plate 13 to move upwards. Therefore, when the staff moves the power supply cabinet normally, the pressing plate 15 will not move downwards and press the touch switch 17, which helps to avoid false alarms.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiment is a preferred implementation scheme of the present utility model. In addition, there are other implementation methods. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
