Mounting structure for appliance guide rail

Abstract

The invention discloses a mounting structure for an appliance guide rail. The mounting structure for the appliance guide rail is that a mounting groove is formed in an appliance base; at least one first fixing clamp is formed on one side of the mounting groove; a first clamping groove is formed between the first fixing clamp and a base; at least one second fixing clamp is formed on the other side of the mounting groove; a second clamping groove is formed between the second fixing clamp and the base; a first limiting block and a second limiting block are respectively formed on two sides of the second fixing clamp and respectively form a first limiting groove and a second limiting groove with the base, wherein the first limiting groove and the second limiting groove are circular arc shaped limiting grooves; two ends of a clamping spring are circular arc shaped and are respectively arranged in the first limiting groove and the second limiting groove and are in line contact with the sidewalls of the first limiting groove and the second limiting groove; and the medium section of the clamping spring is arranged in the second clamping groove. The mounting structure for the appliance guide rail has the advantages that the structure is simplified, the production cost is decreased, the mounting stability of the guide rail is ensured, and the automatic assembling can be conducted.

Description

technical field [0001] The invention relates to the technical field of electrical appliance installation, in particular to an electrical appliance guide rail installation structure. Background technique [0002] In the prior art, electrical appliances such as contactors, circuit breakers, switches, and thermal relays are usually installed with the help of guide rails when they are used and installed. Such as Image 6 As shown in the guide rail installation structure of the contactor 10, an installation groove 20 is formed on the contactor base 10. The width dimension of the installation groove 20 matches the width dimension of the guide rail (not shown in the figure). There is a buckle 30 , and a slot is formed between the buckle 30 and the base 10 . One side buckle 30 is fixedly mounted on the base 10 , while the other side buckle 30 is movably mounted on the base 10 through a spring 40 . [0003] When the guide rail is installed in the installation groove, the guide rail...

AI Technical Summary

Problems solved by technology

[0003] When the guide rail is installed in the installation groove, the guide rail snaps into the slot formed between the buckles on both sides and the base, and the guide rail is fixed by the elastic force of the spring. However, its disadvantages are: 1. The installation structure of the guide rail is relatively complicated, Make the production and processing cost higher, increase the cost; two, the described guide rail installation structural components are more, further increase the cost

[0004] There is another guide rail installation structure in the prior art. A mounting groove is formed on the base of the contactor. Buckles ar
