[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Based on the above-mentioned prior art, when multiple high and low voltage electrical cabinets are combined, the existing bolt connection method is used to reduce the technical problem of the combination efficiency. Please refer to Figure 1-Figure 4 The utility model provides a combined high and low voltage electrical cabinet, which utilizes a combined plate 5 on the side of one electrical cabinet body 1, a combined groove 4 on the upper side of the adjacent combined electrical cabinet body 1, and a limit mechanism 6 fixed in the combined groove 4, so that two adjacent electrical cabinet bodies 1 can be combined and effective shock absorption protection is provided on the combined connection to avoid separation. In addition, the transmission component 65 is used to realize the synchronous movement of the I-type plate 91 to achieve a stable parking effect; the high and low voltage electrical cabinet is composed of an electrical cabinet body 1 wrapped outside the high and low voltage electrical components and an inspection door 2 connected by hinges on one side of the opening of the electrical cabinet body 1. A roller 3 is installed on the bottom surface of the electrical cabinet body 1. The electrical cabinet body 1 can be conveniently moved by the roller 3, so that the combined surface of the electrical cabinet body 1 can be conveniently changed to perform combined operations at any position.

[0024] Among them, in order to solve the problem of low combination efficiency caused by using bolts to combine and connect multiple high and low voltage electrical cabinets, the end faces separated on both sides of the electrical cabinet body 1 in the technical solution are respectively installed with a combination groove 4 and a combination plate 5 for fixing the combination, and a slot 7 is installed at the bottom of the combination groove 4. The combination plate 5 adopts an L-shaped structure, and the lower end of the L-shaped combination plate 5 is matched with the notch of the slot 7 for use;

[0025] Furthermore, a limiting mechanism 6 with a limiting connection is installed at the top of the combination slot 4, and its specific structure is composed of a limiting plate 61 installed horizontally in the combination slot 4, and a plurality of evenly distributed pins 62 are installed on the lower end surface of the limiting plate 61, and the pins 62 are made of cylindrical rubber, and grooves are provided on two separated surfaces of the cylindrical rubber; a plurality of vertically connected pin grooves 8 are provided on the combination plate 5, and the rubber columns are fixed by screws on the relative surfaces of the inner cavity of the pin groove 8, and the size of the rubber columns is consistent with the grooves for damping connection, and the combination plate 5 on one side of an electrical cabinet body 1 is combined and plugged into the combination slot 4 opened on one side of an adjacent electrical cabinet body 1, and at the same time, the pins 62 on the lower end surface of the limiting plate 61 on this side are plugged and combined in the pin grooves 8 opened on the combination plate 5, so as to achieve the effect of stably combining two adjacent electrical cabinet bodies 1;

[0026] Specifically, in order to ensure that the connection between two adjacent electrical cabinet bodies 1 is not affected by external force vibration, a number of evenly distributed shock-absorbing components 63 are installed on the upper end surface of the limit plate 61 in the technical solution. The shock-absorbing component 63 is composed of a movable sleeve and a fixed shock-absorbing spring on the outside of the movable sleeve. When the combination plate 5 is correspondingly combined in the combination groove 4, the limit plate 61 connected to the combination groove 4 through the shock-absorbing component 63 will be plugged and fixed with the combination plate 5. At the same time, the shock-absorbing component 63 will effectively offset the external force vibration through the movable sleeve and the shock-absorbing spring formed thereon, thereby ensuring the stability of the connection.

[0027] In order to stably combine two adjacent electrical cabinet bodies 1 and realize stable parking of the electrical cabinet body 1, a support rod 64 is installed at the center line position of the limit plate 61 in the technical solution, and a transmission component 65 for horizontal transmission is installed at the upper end of the support rod 64, as well as a stabilizing component 9 for stably parking the roller 3 installed on the electrical cabinet body 1;

[0028] Specifically, the stabilizing assembly 9 is composed of an I-shaped plate 91 that is movable and lifted in a cavity 10 that penetrates through the front and rear of the lower part of the electrical cabinet body 1. The upper transverse plate of the I-shaped plate 91 moves up and down in the cavity 10. One side of the I-shaped plate 91 is rotatably connected with a screw rod 92 through a screw rod sleeve that penetrates through it. A linear guide rod 93 is installed on the other side of the I-shaped plate 91 relative to the screw rod 92. The linear guide rod 93 is connected to a guide limit position at a corresponding position of the upper transverse plate of the I-shaped plate 91.

[0029] Furthermore, in order to realize the transmission of power, the transmission assembly 65 in the present technical solution is composed of a first transmission gear 651 and a second transmission gear 652 which are horizontally meshed and connected. The first transmission gear 651 is sleeved and fixed on the upper end of the support rod 64, wherein a section of the support rod 64 is provided with an external thread, and the outer part of the external thread and the corresponding support end on the electrical cabinet body 1 are penetrated by a groove and provided with a matching internal thread. The first transmission gear 651 is rotatably connected to a concentrically distributed support sleeve 653 through a bearing, and the lower end of the support sleeve 653 is welded to the support end of the support rod 64 provided on the electrical cabinet body 1, and is combined in the corresponding combination groove 4 through the combination plate 5. At this time, the combination plate 5 will drive the support rod 64 abutted on the limit plate 61 to move upward. The upper support end of the electrical cabinet body 1 adopts a threaded rotational fitting connection method, so that the upward movement of the support rod 64 drives the support rod 64 to rotate, so that the first transmission gear 651 fixed on the support rod 64 rotates and drives the second transmission gear 652 meshing with it to rotate, and the second transmission gear 652 is fixed on the screw rod 92. At this time, the screw rod 92 will be driven to rotate by the second transmission gear 652. Since the first transmission gear 651 and the second transmission gear 652 are meshingly connected on the same horizontal plane, opposite drive is achieved, thereby driving the I-type plate 91 that is rotationally connected to the screw rod 92 to move vertically downward under the guidance of the linear guide rod 93 on the other side, so that the front and rear support parts of the I-type plate 91 contact the ground, maintaining the overall stability of parking.

[0030] Among them, in order to improve the heat dissipation capacity inside the electrical cabinet body 1, a radiator 11 is installed at the top of the cavity 10 in the present technical solution and is connected to the bottom of the mounting cavity for multiple electrical components arranged on the electrical cabinet body 1. The radiator 11 is fixed to the top of the cavity 10 by screws. Since the radiator 11 is fixed in the cavity 10 and the cavity 10 is arranged at the lower part of the electrical cabinet body 1, the design of the cavity 10 can, on the one hand, raise the height of the mounting cavity in the electrical cabinet body 1 from the ground to prevent water from entering the mounting cavity on the electrical cabinet body 1, and on the other hand, reduce the entry of dust from the outside, thereby maintaining good heat dissipation capacity while reducing the entry of dust.
