door lock

Abstract

The invention provides a door lock which comprises a cam, a bias force device, a positioning device and a slide pin, wherein the cam is equipped with a cam hook and a shaft, the cam can be rotated around the shaft, the cam comprises a head part and a tail part, and the cam head part has an opening; the bias force device applies bias force to the cam; the positioning device is equipped with a first stable position and a second stable position; and the slide pin comprises a first end and a second end, the first end of the slide pin is fixed on the tail part of the cam, and the second end of the slid pin forms movable fitting with the positioning device, so that the slide pin can move between the first stable position and the second stable position in the positioning device when the cam is rotated. The door lock provided by the invention is characterized in that a door of electric appliance equipment can be opened by pushing; the lock has a small size and a compact structure; and the production cost can be effectively reduced.

Description

Technical field [0001] The invention relates to a door lock of an electrical appliance (such as a washing machine), and more particularly to a door lock that realizes opening the door of an electrical appliance (such as a washing machine) by pushing the door. Background technique [0002] The door lock can be used to lock or open the door of electrical equipment (such as washing machine). For most existing door locks, when opening the door of an electrical appliance (such as a washing machine), the user must first hold the handle on the door of the electrical appliance (such as a washing machine), and then apply a pulling force outwards. Open the door. This kind of operation brings at least the following problems: 1) When the door of electrical equipment (such as washing machine) is pulled outwards, it is often necessary to use a large force to open the door, which is more laborious; 2) The action of sliding the door often requires manual operation , But when the hands are occu...

AI Technical Summary

Problems solved by technology

This operation brings at least the following problems: 1) when pulling the door of an electrical appliance (such as a washing machine) outwards, it is often necessary to use a relatively large force to pull the door open, which is laborious; 2) the action of pulling the door often requires manual operation , but when the hands are occupied (such as holding a pile of clothes to be washed) or there are other reasons (such as hand injuries), it is very inconvenient to pull the door at this time; 3) In order to realize the sliding door, it is necessary to design on the door The handle may not only affect the appearance of electrical equipment, but also increase the design and production costs

However, for the above-mentioned existing door locks that realize opening the door by pushing the door, there are problems of large volume, complex structure and high production cost.
