Miniature high-temperature-resistant mechanical timing power-on and power-off device

Abstract

The invention discloses a miniature high-temperature-resistant mechanical timing power-on and power-off device, which comprises a machine core upper clamping plate, wherein a machine core lower clamping plate is arranged on the machine core upper clamping plate, a mounting cavity is formed between the machine core lower clamping plate and the machine core upper clamping plate, a strip wheel shaftis rotationally arranged on the machine core lower clamping plate, the front end of the machine core upper clamping plate is oppositely provided with a moving terminal reed and a static terminal reed,an elastic sheet is arranged at the rear end of the movable terminal reed, a movable contact is arranged on the elastic sheet, a static contact corresponding to the movable contact in position is arranged at the rear end of the static terminal reed, a positioning disc is arranged in the mounting cavity, and an on-off device matched with the positioning disc, the movable contact and the static contact is arranged in the mounting cavity. Compared with the prior art, the mechanical timing power-on and power-off device has the advantages that through reasonable adjustment of gear transmission parameters and structural layout, miniaturization of the mechanical timing device is achieved, so that the attractiveness of appearance design of household appliances is improved, and the production material cost of the household appliances can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of timing power-on, in particular to a miniature high-temperature-resistant mechanical timing power-on and power-off device. Background technique [0002] With the continuous innovation of mini household appliances, customers require miniaturization of mechanical timing power-on and power-off devices to meet the design and installation space requirements. The high-temperature-resistant mechanical timing power-on and power-off devices sold in the existing market are large in size. Can not meet the new market demand. Contents of the invention [0003] The invention realizes the miniaturization of the mechanical timing device by rationally adjusting the parameters and structural layout of the gear transmission. This utility model solves the problem of the installation space of the timing device for mini household appliances, and improves the appearance of the household appliances. The aesthetics of the desig...
