Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, a direct-acting plunger type actuator for a travel switch includes a transmission mechanism, a push rod 1, and a casing 2 with upper and lower openings. The transmission mechanism includes a plunger 3 with an axial groove at the lower end. , the plunger 3 is passed through the casing 2, the upper end of which is exposed outside the upper opening of the casing 2, the upper end of the push rod 1 is fixed in the groove of the lower end of the plunger 3, and the casing The openings at both ends of 2 are adapted to the plunger 3 and the push rod 1 respectively.

[0016] There is a stepped inner wall in the groove of the lower end of the plunger 3, and the upper end of the push rod 1 fixes the push rod 1 in the groove through a support 4 fixed with the stepped inner wall, and is located in the push rod 1. The middle part is sequentially provi...

Abstract

The invention relates to a direct-acting piston actuator for a travel switch, comprising a transmission mechanism, a pushing rod and a casing with an upper opening and a lower opening. The transmission mechanism comprises a piston. The lower end of the piston is provided with an axial groove. The piston is perforated into the casing. An upper end of the piston is exposed to the upper opening of the casing. An upper end of the pushing rod is fixed in the groove at the lower end of the piston. The openings at the two ends of the casing are respectively adapted to the piston and the pushing rod. Compared with the prior art, the direct-acting piston actuator for the travel switch has the characteristics of simple structure, stable performance, strong reliability, etc.

Description

technical field [0001] The present invention relates to a travel switch actuator, in particular to a direct-acting plunger type actuator for travel switches. Background technique [0002] The travel switch can convert mechanical movement into electrical signals to control mechanical action or program control, so it is widely used in control systems. In practical applications, there are defects such as unstable performance and unreliable work. In recent years, although many important control occasions have been replaced by foreign brand products, because the protection function of such products is not perfect at present, it is relatively common for the mechanism to be stuck due to the abnormal operation of the site, and the malfunction caused by the failure of the action. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a direct-acting plunger type actuator for a travel switch with simple structure, stable performa...
