Description

Electric cabinet

Technical Field

The utility model relates to an electric cabinet, in particular to an electric cabinet suitable for a high-speed well pump.

Background

Along with the development of the well pump industry, the traditional well pump has the problems of huge volume and inconvenient installation and well descending, and is gradually replaced by a high-speed well pump, and the high-speed well pump has relatively small volume and can be conveniently installed and well descending. The high-speed well pump often needs to be matched with an electric cabinet, the electric cabinet comprises a box body, a back plate fixed inside the box body, and a controller is fixed on the back plate through self-tapping screws. Because the backplate is thinner, the controller needs to be dismantled often again and be maintained or change, and after many dismouting, the screw hole on the backplate becomes invalid easily, leads to the controller unable to fix. If the common screw is used to match with the nut to fix the controller, the back plate is firstly disassembled during fixed installation, the nut is used to lock the common screw behind the back plate, so that the controller is fixed on the back plate, and then the back plate fixed with the control box is fixed on the back wall of the box body. When the controller is removed, the entire back plate is removed, then the screws are removed to remove the controller from the back plate, and then the back plate is fixed to the back wall. Therefore, the common screw and nut matched mode is adopted to fix the controller, so that the problems of complex disassembly and assembly, low disassembly and assembly efficiency, high labor intensity and the like exist.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provide an electric cabinet, wherein a cushion block is additionally arranged at the rear side of a back plate, the thickness of a self-tapping screw acting on the back plate is increased, when a controller is dismounted for a plurality of times, threaded holes on the back plate and the cushion block are not easy to lose effectiveness, and the self-tapping screw can be effectively fixed on the back plate and the cushion block for a long time, so that a control block is convenient to dismount, the dismounting efficiency is improved, and the dismounting strength is reduced.

The technical aim of the utility model is mainly solved by the following technical scheme: the utility model provides an electric cabinet, includes the box, fixes backplate in the inner chamber of box, through self-tapping screw fixing the controller on the backplate, its characterized in that the back of backplate sets firmly the cushion, self-tapping screw passes in proper order connecting hole on the controller backplate with the cushion, self-tapping screw is fixed the backplate with on the cushion. The cushion block is additionally arranged at the rear side of the back plate, the thickness of the self-tapping screw acting on the back plate is increased, when the controller is disassembled and assembled for many times, the threaded holes on the back plate and the cushion block are not easy to lose efficacy, and the self-tapping screw can be effectively fixed on the back plate and the cushion block for a long time, so that the control block is convenient to disassemble and assemble, the disassembly efficiency is improved, and the disassembly and assembly strength is reduced.

And further optimizing the scheme of cushion block setting: the cushion block 8 is fixed on the back surface of the back plate 1 through a screw 11, the screw 11 penetrates through the back plate 1 from front to back, and the screw 11 is provided with a nut 12 on the back side of the back plate 1, so that the cushion block 8 is fixed on the back surface of the back plate 1. On the basis of the technical scheme, the connection direction of the screw 11 for fixing the cushion block 8 is further limited, so that the nut 12 is hidden at the rear side of the back plate 1, and the front side of the back plate 1 only exposes the screw head part of the screw 11, thereby being beneficial to the simplicity of the whole structure and improving the visual effect of the whole product.

The setting position of the screw 11 is located at the periphery of the setting position of the self-tapping screw 10, and is used for avoiding the self-tapping screw 10 and the controller 9. The self-tapping screw 10 is convenient to use, and tools such as a screwdriver and the like are convenient to detach in the avoiding space, so that the operation is convenient, and the operation efficiency is improved.

The scheme of setting up of cushion 8 has multiple, and the main points of cushion 8 setting up mainly embody in: the partial arrangement of the cushion block 8 is beneficial to saving materials and reducing cost, is beneficial to reducing the overall weight, and is required to be matched with the arrangement position of the fixed foot 13 of the controller 9.

The scheme of the cushion block 8 disclosed in this embodiment is as follows: the upper side and the downside of controller 9 set up fixed foot 13 respectively, fixed foot 13 all towards the periphery of controller 9 extends, cushion 8 is rectangular shape, cushion 8 is two, correspond respectively the upper end and the lower extreme setting of controller 9, and with fixed foot 13 cooperation, self-tapping screw 10 pass screw hole on the fixed foot 13 and fix on backplate 1 and cushion 8.

Further optimizing the above scheme, the controller 9 is in a cuboid shape, the four corners of the controller 9 are respectively provided with corresponding fixing feet 13, and the fixing feet 13 extend outwards along the diagonal direction of the controller 9.

Still further preferably, four fixing pins 13 are disposed on the controller 9, two fixing pins 13 are disposed on the upper side and the lower side of the controller 9, and two fixing pins 13 on each side are fixed on a corresponding cushion block 8.

Example 2: as shown in fig. 1-3, an electric cabinet, based on embodiment 1, differs from embodiment 1 in the preferred scheme of the different arrangement schemes of the cushion block 8: the left side and the right side of the controller 9 are respectively provided with a fixed foot 13, the fixed feet 13 extend towards the periphery of the controller 9, the cushion block 8 is in a strip shape, two cushion blocks 8 are respectively arranged corresponding to the left side and the right side of the controller 9 and are matched with the fixed feet 13, and the tapping screw 10 penetrates through threaded holes in the fixed feet 13 and is fixed on the back plate 1 and the cushion block 8.

Further refine the above scheme: four fixing feet 13 are arranged on the controller 9, two fixing feet 13 are respectively arranged on the left side and the right side of the controller 9, and the two fixing feet 13 on each side are fixed on a corresponding cushion block 8.

The foregoing description is only of the preferred embodiments of the utility model and is not intended to limit the utility model. In the above-described embodiments, the present utility model is susceptible to various modifications and changes.
