Locking and unlocking structure of switching device

Abstract

The invention discloses a locking and unlocking structure of a switching device, and the structure has effects of reducing occupation of the structural space and being simple in assembly and low in loss. The switching device comprises a body and an operation button arranged on the body; the body is provided with first and second stop portions, the body defines a cavity, a reaction cylinder is combined with a wiring module. A first elastic device is configured between the reaction cylinder and the body, so that the cylinder is in the initial combination position (or the position where the wiring module is in an ON state). The reaction cylinder is assembled with a limiter and a second elastic device; and when the second elastic device moves in response to motion of the operation button, thelimiter is driven to move from the position of the first stop portions to the position of the second stop portions, so that the wiring module is in an OFF state. The problem that a known structure needs a larger operation force and is low in structural stability is solved.

Description

technical field [0001] The present invention relates to a locking and unlocking structure of a switch device; in particular, it refers to a combination of a switch device including a body, a reaction cylinder and a limiter. The second elastic device achieves the invention of labor-saving operation and low component loss. Background technique [0002] Applied in electrical, electronic, and automatic control systems, the switch device that allows the operator to operate the machine or power on and off is a well-known art. The old law has also revealed that this type of switchgear is used as an emergency switch. In the event of improper operation by personnel, equipment failure, etc., personnel can perform emergency power-off or circuit-break operations to avoid serious injury or loss. For example, China Taiwan No. 94222288 "Emergency Switch Structure for Test Equipment" and No. 98201163 "Emergency Switch Device" patent cases have provided typical embodiments. [0003] The em...

Problems solved by technology

And, the known structural matching type is easy to cause wear of the components, the difference in the force of the cooperation between the various inserts and the different degree of wear of each insert, which affects the operation button and the base must be kept in the center position as much as possible, and the Reduce the stability of the conduction state of the contacts of the operation button, the base and the wiring module, and the quality of the entire emergency switch device, etc.
