Technical Field

The invention relates to the technical field of electricity, in particular to an electric part fixing device.

Background

The electrical part is common and indispensable equipment in the field of electrical appliances; such as switches, electricity meters, circuit breakers, contactors, relays, and the like. At present, electric component widely adopts the guide rail installation, specifically is: install the guide rail in regulator cubicle or the electric box earlier, install the electric piece on the guide rail again, be provided with the buckle structure that matches with the guide rail on the electric piece, buckle structure is made by plastics, and buckle structure is elastomeric element, can stretch out and draw back in certain extent to the realization is with guide rail lock and is thrown off. The traditional buckle structure mainly adopts a press-in mode, an inclined surface is arranged on the buckle, and the buckle retreats during press-in, so that the installation of an electric component is realized; when the electric part is dismantled, the buckle is transversely drawn outwards along the guide rail, and the separation of buckle and guide rail is realized. The traditional buckle structure has the following defects: firstly, the elasticity of the buckle made of plastic is limited, so that the stroke of the buckle is limited, and the buckle has certain limitation; secondly, the elastic property of the buckle is reduced along with the aging of the plastic, and even the buckle is failed; thirdly, the friction force between the plastic buckle and the guide rail is large due to the pressing-in mode, so that the buckle is easy to wear and short in service life; fourthly, the dismounting process is complicated, and even the convenience of operation is influenced by the aid of tools.

In the prior art, chinese patent CN103260376B discloses a stop member and an electrical component mounting and fixing device having the stop member, wherein the electrical component fixing device includes a fixing base and a fixing plate. The stopping piece slides along a track on the fixed seat. The stopper comprises an elastic piece, the elastic piece is used for positioning the stopper on the track of the fixed seat and also used for providing an elastic restoring force, and the elastic restoring force pushes the stopper to press the fixed plate along the sliding direction parallel to the stopper. The invention also provides an electrical component mounting and fixing device with the stop piece. The invention utilizes the elastic deformation action of an elastic piece arranged on a stop piece to fix the fixing plate for fixing the electrical element, has simple structure and ensures that the installation and the disassembly processes of the electrical element are simple and easy. However, the device mainly depends on the deformation generated by the supporting bar to complete the disassembly and assembly of the electric appliance element, and the elastic performance of the supporting bar is limited, so that the stroke of the retainer is limited, the disassembly and assembly of the electric appliance element are inconvenient, and certain limitation is realized; and the support bars can age with the increase of the use frequency and the time, so that the stop piece fails; in addition, the support bars and the positioning columns are easy to wear, so that the service life of the equipment is short.

In the prior art, chinese patent CN206472423U discloses an electrical component fixing structure, which includes an electrical component, a pin movably mounted on the electrical component and pressed between the electrical component and the electrical component, and an electrical guide rail provided with a guide groove, wherein the pin can be positioned at a first position where the pin is engaged with the guide groove and a second position where the pin is disengaged from the guide groove. The principle that this application and tradition mode of impressing is the same, realizes electrical components's fixed through extrusion elastic rod, also has the defect the same with traditional buckle structure.

Disclosure of Invention

The invention provides an electric component fixing device, aiming at the technical problems of inconvenient operation, short service life, easy aging and failure and limitation of the existing electric component fixing device.

The technical scheme adopted by the invention is as follows: electric piece fixing device, including electric piece and the guide rail of fixed electric piece, be provided with the first spout that matches with the guide rail on the electric piece, still include:

the second sliding chute is arranged on one side of the first sliding chute where the electric part is located, and the second sliding chute is vertical and communicated with the first sliding chute;

the buckle is movably arranged in the second sliding groove, and the end part of the buckle extends out of the second sliding groove and is spaced from the first sliding groove by a certain distance;
