Description

Technical Field

[0001] The utility model relates to the technical field of electric control boxes, in particular to a convenient disassembly and assembly type electric control box. Background Art

[0002] The electric control box is an important electrical control device that can effectively manage and control various electrical equipment in the power system to ensure the safe, reliable and efficient operation of the system. Therefore, it is widely used in industrial automation, public facilities, multi-functional detection and intelligent buildings. Its structure generally contains one or more modules for control, measurement, signal, protection and regulation, and the manufacturer is responsible for fully assembling them together with structural components.

[0003] In actual use, the electric control box generally needs to be fixed by guide rails, but conventional guide rail clips are difficult to disassemble and assemble, and the electric control box is easy to fall off the guide rail when the mass is large; and in some special scenarios, such as when the guide rail is set vertically, it is required that there is a large friction between the guide rail clips and the guide rails to prevent the electric control box from sliding along the vertically set guide rails; for example, when the electric control box needs to freely adjust the horizontal position, it is necessary to reduce the friction between the guide rail clips and the guide rails. However, these technical requirements are extremely difficult to achieve while meeting the requirements of convenient disassembly and assembly and anti-falling.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to design a convenient disassembly and assembly type electric control box to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the utility model. Utility Model Content

[0010] The preferred technical solution is that when the guide rail is arranged in a vertical or inclined direction, the functional pressing block is made of a material with a high friction coefficient to prevent the guide rail clamp from sliding along the guide rail under the action of the electric control box's own gravity.

[0011] The preferred technical solution is: when the guide rail is arranged in the horizontal direction, the functional pressing block is made of a material with a low friction coefficient, so that the electric control box can slide freely along the guide rail through the guide rail clamp.

[0012] The preferred technical solution is: there are two guide rail clips, which are arranged in parallel to avoid the electric control box falling off due to the failure of one of the guide rail clips.

[0013] The preferred technical solution is: at least two groups of guide slots are provided on the guide baffle, and both sides of the universal daughter card are slidably connected to the guide slots, so that the ease of disassembly, assembly and positioning of the universal daughter card is improved through the guide slots.

[0014] The preferred technical solution is: a fixing screw hole is provided on the guide baffle, and an auxiliary extraction screw is provided on the universal daughter card, and the auxiliary extraction screw is connected to the fixing screw hole to facilitate the disassembly and assembly between the universal daughter card and the guide baffle.

[0015] The preferred technical solution is: a PCIE connector is provided on the universal daughter card, a PCIE interface is correspondingly provided on the backplane CPU module, and the PCIE connector and the PCIE interface can be connected in a plug-in manner.

[0016] Due to the application of the above technical solution, the convenient disassembly and assembly type electric control box provided by the utility model has the following advantages over the prior art:

[0017] (1) The guide rail clamp is formed by using a clamp groove, a triangular prism-shaped protrusion and a splint-shaped clamp groove, thereby reducing the difficulty of disassembling and assembling the guide rail clamp and the guide rail;

[0018] (2) An anti-dropout boss is provided in the groove of the clamp, and the anti-dropout boss is used to change the direction of the force between the guide rail and the triangular prism-shaped protrusion, so as to prevent the triangular prism-shaped protrusion from being deformed due to the force and falling off the guide rail;

[0019] (3) A functional pressure block is arranged in the groove of the clamp, and the friction between the guide rail clamp and the guide rail is changed by using the functional pressure block made of different materials. BRIEF DESCRIPTION OF THE DRAWINGS
