[0002] As the name implies, the dual power supply control cabinet has two power supply lines, one is the normal power supply and the other is the backup power supply. The normal power supply is the city power supply, which is the power supply of our national power grid; the backup power supply is usually generated by a diesel engine; the core function of the dual power supply control cabinet is to switch between the normal power supply and the backup power supply. The dual power supply control cabinet is mainly composed of a dual power supply automatic switching device, which can automatically switch between the normal power supply and the backup power supply according to demand, and timely ensure the reliability and continuity of power supply. When the normal power supply fails due to power outages, undervoltage, overvoltage, phase failure, frequency offset and other faults, it will automatically switch to the backup power supply under the control of the dual power supply control cabinet, thereby ensuring the continuous and uninterrupted operation of related electrical equipment.

[0003] At present, mounting brackets for components related to power control are set up inside the dual power control cabinet. When the components are assembled in rows and columns, the mounting brackets are relatively fixed in connection, which causes inconvenience in actually adjusting the installation spacing between the brackets. In addition, the components are mostly installed using fasteners to achieve fastening connections, which makes the connections complicated when the components are subsequently disassembled and maintained. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a dual power switching control cabinet. The technical problem to be solved by the utility model is: there is inconvenience in actually adjusting the installation spacing between the brackets inside the dual power switching control cabinet, and there is cumbersome connection when disassembling and maintaining the components behind the cabinet door.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dual power switching control cabinet, comprising a base, a cabinet arranged on the base, a cabinet door connected to the cabinet by hinge rotation, and a dual power automatic switching switch arranged on the cabinet door, a pair of light rods are fixedly connected inside the cabinet, a plurality of device connection plates are slidably connected to the pair of light rods, a column that movably penetrates the plurality of device connection plates is fixedly connected inside the cabinet, and a card block group is fixedly connected to the column, and each device connection plate is provided with a card fixing structure for movably connecting the card block group;

The clamping plate movably penetrates the device connection plate and is movably clamped with the clamping block group. A plurality of elastic connectors and device assembly seats are arranged on each device connection plate, and a limiting groove for elastic abutment of the elastic connector is arranged on the device assembly seat.

[0007] In a preferred embodiment, the clamping block group is arranged with a plurality of clamping blocks longitudinally distributed in sequence, and the clamping blocks are arranged with an upward inclination angle.

[0008] In a preferred embodiment, the clamping plate is clamped with two adjacent clamping blocks, and a pre-measure slot for the clamping plate to pass through is arranged on the device connection plate.

[0009] In a preferred embodiment, the elastic connector includes a telescopic groove penetratingly opened on the device connection plate, a compression spring arranged in the telescopic groove, and a pair of limiting round heads slidably connected in the telescopic groove. The pair of limiting round heads are located at both ends of the compression spring, and the limiting round heads are elastically abutted against the limiting groove through the compression spring.

[0010] In a preferred embodiment, the device assembly seat has a U-shaped structure, and one end of the device assembly seat is fixedly connected with a mounting plate with a mounting hole. Rubber strips are fixedly connected to both the top and bottom inside the device assembly seat, and one end of the rubber strip is provided with an inclined mouth.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. For a dual-power switching control cabinet of the present utility model, under the action of using the smooth rod to provide balanced guiding and sliding for the device connection plate, the connection between the clamping plate and the clamping block group is controlled by opening and closing the pull rod. The open pull rod can conveniently pull the device connection plate to move vertically to adjust the installation spacing. The closed pull rod can make the clamping plate stably snap into the clamping block group under the action of gravity. And due to the upward inclination angle setting of the clamping blocks, the locking stability of the device connection plate can be improved.

[0015] 2. A dual power switching control cabinet of the utility model is provided with a limiting round head on the device connecting plate for realizing extrusion and extension by means of a compression spring. The device assembly seat loaded with the components can be inserted into the device connecting plate to realize elastic abutment with the limiting round head. Since the limiting round head can realize extrusion connection, the connection position of the device assembly seat can be limited and the disassembly by pulling can be satisfied, thereby reducing the complexity of component connection.

DETAILED DESCRIPTION

[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combined with reference Figure 1-Figure 5 The utility model provides a dual power switching control cabinet, including a base 1, a cabinet 2 arranged on the base 1, a cabinet door 3 connected to the cabinet 2 by hinge rotation, and a dual power automatic switching switch 4 arranged on the cabinet door 3, characterized in that: a pair of light rods 5 are fixedly connected inside the cabinet 2, and a plurality of device connecting plates 6 are slidably connected to the pair of light rods 5. The device connecting plates 6 can provide installation support for components of associated power control, and a column 7 that movably penetrates a plurality of device connecting plates 6 is fixedly connected inside the cabinet 2, and a block group 8 is fixedly connected to the column 7. In the present application, a through groove that adapts to the width of the column 7 and the block group 8 is provided on the device connecting plate 6, so that the device connecting plate 6 can pass through the column 7 and the block group 8 at the position, and each device connecting plate 6 is provided with a fixing structure 9 for the active connection of the block group 8.

[0025] The fixing structure 9 includes an articulated seat 91 fixedly connected to the device connecting plate 6, a pull rod 92 rotatably connected to the articulated seat 91 and a clamping plate 93 fixedly connected to the pull rod 92. The clamping plate 93 movably passes through the device connecting plate 6 and is movably clamped with the clamping block group 8. Each device connecting plate 6 is provided with a plurality of elastic connectors 10 and a device assembly seat 11. The device assembly seat 11 is provided with a limiting groove 12 for elastically abutting the elastic connector 10.

[0026] The block group 8 is composed of a plurality of blocks which are longitudinally distributed in sequence, and the blocks are inclined at an elevation angle.

[0027] The card plate 93 is engaged with two adjacent card blocks, and a pre-measured slot 13 for the card plate 93 to pass through is provided on the device connecting plate 6. The card plate 93 cooperates with the card block which is inclined at an elevation angle. In this way, when the card plate 93 is engaged with the adjacent card blocks, the gravity applied by the device connecting plate 6 and the drooping effect of the pull rod 92 when it rotates to the hinge seat 91 can improve the stability of the locking position of the device connecting plate 6 without providing an outward flipping force to the card plate 93. The pre-measured slot 13 can provide an effective moving path for the card plate 93.

[0028] Specifically, by turning the traction rod 92 around the connection point of the hinge seat 91, the rod 92 can drive the clamping plate 93 to disengage from the clamping block group 8. At this time, the rod 92 can drive the device connection plate 6 to move vertically on the optical rod 5 to adjust the distance between adjacent device connection plates 6 to meet the requirements of the vertical installation distance. Similarly, when the rod 92 drives the clamping plate 93 to connect to the clamping block group 8, due to the drooping of the rod 92, the gravity of the device connection plate 6, and the angle of the clamping block, the device connection plate 6 can achieve a stable locking effect.

[0029] The elastic connecting member 10 includes a telescopic groove 101 formed through the device connection plate 6, a compression spring 102 disposed in the telescopic groove 101, and a pair of limit round heads 103 slidably connected in the telescopic groove 101. The pair of limit round heads 103 are located at both ends of the compression spring 102, and the limit round heads 103 are elastically abutted against the limit groove 12 through the compression spring 102. In this application, the telescopic groove 101 has a groove structure that is large in the middle and small at both ends, and such a setting can prevent the limit round heads 103 from coming out. A sliding seat is integrally provided at the bottom of the limit round head 103, which can stably slide the limit round head 103 in the telescopic groove 101.

[0030] The device assembly seat 11 has a U-shaped structure, and one end of the device assembly seat 11 is fixedly connected with a mounting plate 14 with mounting holes. The mounting plate 14 can be connected to the component with screws. Rubber strips 15 are fixedly connected to both the top and bottom inside the device assembly seat 11, and one end of the rubber strip 15 is provided with an inclined mouth. The inclined mouth can facilitate the device assembly seat 11 to drive the rubber strip 15 to be clamped onto the device connection plate 6, and the rubber material is used to achieve the pre-tightening effect.

[0031] A guide inclined groove 16 is formed in the inner side wall of the device assembly seat 11 and is horizontally butted with the limit groove 12. The setting of the guide inclined groove 16 can limit the movement path of the device assembly seat 11 when the device assembly seat 11 is inserted facing the device connection plate 6. Specifically, the guide inclined groove 16 corresponds to the outside of the clamping round head 103, which can accurately control the abutment of the clamping round head 103 and the limit groove 12. The clamping round head 103 is subjected to the elastic tension force provided by the compression spring 102. In this way, the clamping round head 103 can limit the position of the device assembly seat 11 by vertically tensioning it. And due to the round head at the end of the clamping round head 103, by applying a dragging force to the device assembly seat 11, the connection of the device assembly seat 11 on the device connection plate 6 can be released, facilitating the removal of the component.

[0032] A cable organizer 17 is fixedly hung at the bottom of each device connection plate 6, and at least two cable organizers 17 are arranged on the device connection plate 6. A cable organizer 2 18 is fixedly connected to the inner wall of the cabinet 2, and a plurality of cable organizers 18 are arranged. Because the cable organizer 17 changes position along with the device connection plate 6, the cable organizer 17 can provide wire management for the components on the installation plate 14 in real time. At the same time, the cable organizer 18 is arranged longitudinally, which can facilitate the extension and management of the wires on the cable organizer 17 for the purpose of organizing the wire harness.
