Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the lack of a gap compensation mechanism in the prior art dust-proof latch, there is a gap between the pin rod and the pin hole in the lock pin mechanism, and it is easy to shake under the action of an external force, and the lock cannot be realized. Tight and noise-generating defects, thus providing a dust-proof plug with backlash compensation,

Abstract

The invention discloses a dustproof bolt with a gap compensating function. The dustproof bolt comprises a pin base arranged on a door / window frame, a movable pin slidingly arranged in a door / window leaf and suitable for inserting in the pin base, a dustproof piece arranged in the pin base, and a spring for applying partial pressure to the dustproof piece in an opening direction of the pin base. The dustproof bolt further comprises a gap compensating piece arranged in an opening of the pin base, positioned in a direction of opening and closing the door / window leaf, performing a reciprocating motion in a direction of the movable pin inserted in the pin base and applying partial pressure to the movable pin.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a dust-proof latch with a gap compensation function. Background technique [0002] During the use of the ground bolt, dust and floating soil can easily enter the socket, causing the insertion rod to be inflexible or unable to be inserted into the socket, which affects people's use. Therefore, dust-proof plugs are widely used in daily life to effectively prevent dust from entering the socket. [0003] The prior art, such as the patent document with the publication number CN201321767Y, discloses a dust-proof door latch, such as Figure 4 As shown, it includes an insertion rod (8) and a socket (9), a spring is arranged in the socket (9), and the top end of the spring is connected to the cover (10). In the natural state, the cover (10) is connected to the top of the socket (9). flush. It solves the problem that the bolt socket is easy to enter the soil. When the door needs to be...
