Abstract

The invention discloses a breaking spring compression device, which comprises a support seat, a drive mechanism and a locking structure, wherein the support seat is provided with a limiting structure for moving towards one side, far away from a breaking spring, of a spring seat in a breaking spring assembly; the drive mechanism comprises a drive part and a transmission part; the transmission part moves towards the direction of the spring seat under the action of the drive part and compresses the breaking spring; a perforating hole through which a pull rod of the breaking spring assembly passes is formed in the transmission part; and the locking structure is used for keeping the breaking spring in a compressed state after the breaking spring is compressed in place. Through the compression device disclosed by the invention, the breaking spring can be conveniently pre-compressed, so that subsequent installation of the breaking spring assembly on a breaker is facilitated.

Description

technical field

[0001] The invention relates to an opening spring compression device. Background technique

[0002] Compression spring is an elastic element widely used in industries such as machinery and electrical appliances. In the compression spring assembly, its elasticity can be used to store energy, control the movement of parts and other functions. For example, opening springs used in circuit breakers, such as figure 1 As shown, it is a structural diagram of a circuit breaker. The circuit breaker includes an opening spring assembly. The opening spring assembly includes a pull rod 40 and an opening spring 50 sleeved on the pull rod 40 . The pull rod 40 is provided with a spring seat 60 . The upper end of the pull rod 40 is connected to the crank arm 30 , the lower end of the pull rod 40 passes through the support plate 70 , and the opening spring 50 is above the support plate 70 . The opening spring needs to be pre-compressed before installation, otherwise pre-comp...
