Description

Convenience type lock pin lock

Technical field:

The utility model relates to a kind of lockset, the particularly a kind of convenience type lock pin lock that can lock without key.

Background technology:

In the existing lock, lock and unblank all must use key, very inconvenient.The someone has invented automatic door lock for this reason, is exactly one of them as the following Chinese patent application relevant with the utility model.

Title: the convenient automatically lock of a kind of three dead bolt; Notification number: CN2421379Y; The day for announcing: February 28 calendar year 2001; The patent No.: 00227206.7; The convenient automatically lock of this three dead bolt comprises lock housing, handle etc., its principle is to be provided with rotating button hook in lock housing, in the time of in main tongue is withdrawn lock housing, button hook fastens main tongue, and at closing time, doorframe clashes into oblique tongue, and tiltedly tongue clashes into button hook again and makes the button hook rotation and thread off with main tongue, and main tongue stretches out under spring action outside the lock housing locks door; With the key rotational lock core main gyrus lingulais is contracted in the lock housing when unblanking, simultaneously with button hook jack-up, after main tongue bounced back fully, button hook fastened main tongue in spring action falls to becoming owner of the groove of tongue again.Though convenient when this lockset uses, its shortcoming is that main tongue does not have self-locking mechanism, when the gap of door was too big, instruments such as available iron plate stretched in the gap of door main tongue headed in the lock housing by force lock are opened, so its theftproof performance is not high.

Summary of the invention:

Technical problem: exist in the existing lock or use inconvenience, the problem that theftproof performance is not high, the purpose of this utility model just provides a kind of convenience type lock pin easy to use, that theftproof performance is high and locks, it solved exist in the existing lockset otherwise use inconvenience or the not high technical problem of theftproof performance.

Technical scheme:

The purpose of this utility model is achieved in that a kind of convenience type lock pin lock, comprises tapered end, lock body, main tongue, oblique tongue, handle; It is characterized in that being provided with in the lock body rotating safeguard driving lever, the safeguard driving lever links with oblique tongue driving lever; Being provided with in the lock body can be around the safeguard that is fixed on the axis of a cylinder rotation on the lock body, safeguard stretches out upper limb by safeguard driving lever one side and the safeguard driving lever matches, the opposite side of safeguard is a bottom wing, and bottom wing and tapered end driving lever match, and the side that safeguard stretches out upper limb also is provided with lock dog; Be provided with torsion spring between safeguard and lock body, make the lock dog on the safeguard press to main tongue; Lock body is provided with lead, have slotted eye on the main tongue, this slotted eye blocks lead main tongue is play the guiding role, main tongue is provided with position-limited wing, the both sides of position-limited wing are bottom and upper segments, the distance of top and main tongue axis is greater than distance following and main tongue axis, and the outside of position-limited wing has one section to tilt to bottom; Be provided with between main tongue and lock body and make main tongue stretch out the outer main tongue spring of lock body.

Described convenience type lock pin is locked, and it is characterized in that insuring having breach on the driving lever, and tiltedly the tongue driving lever is provided with the Ka Tai that can stretch in this breach.

Described convenience type lock pin lock is characterized in that lead is with location-plate outward, suit master tongue spring on the guide peg that stretches out on the location-plate, and the other end of guide peg stretches in the hole that is provided with on the main tongue.

Operating principle:

Beneficial effect:

Owing to adopted technical scheme described in the utility model, in lock body, be provided with safeguard, even when the gap of door is too big, iron plate stretches in the gap of door and main tongue can not be headed in the lock housing by force, so its theftproof performance height; And only need at closing time and will be contained in handle backward rotation on the door with the safeguard driving lever links, thereby the safeguard driving lever just will safeguard be stirred and is discharged main tongue, main tongue is ejected outside the lock housing locks door, after main tongue stretches out outside the lock body, lock dog on the safeguard contacts with bottom on the main tongue, thereby prevents that main tongue from bouncing back under external force; And at this moment because of safeguard is shifted, the safeguard driving lever bumps less than safeguard, so handle can not change the safety position of safeguard; Therefore, convenience type lock pin lock described in the utility model is easy to use, theftproof performance is high.
