Description

A kind of door lock

The utility model relates to a kind of lock, relates to a kind of door lock of pin with lock particularly.

In the prior art, common door lock lock pin is the clinohedral that has tapering, only needs when locking a door one to bump and can finish gently.But this door lock poor safety performance is inserted from crack between a door and its frame with rigid thin slice and just to be easy to door-lock opening.In addition, after door lock was run into, in case key is forgotten indoor, just very difficult door is opened entered within doors.For overcoming above-mentioned shortcoming, having occurred a kind of lock pin in the market again is the door lock of facing body directly, and this door lock needs just can lock or open door lock by means of key.But this door lock easily causes the frequent impact of lock pin and pin-and-hole box owing to face the exposure outside for a long time of body lock pin directly, has both damaged door lock, has also caused noise and inconvenience.

The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and security performance is good, long service life.

For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model comprises lock housing, lock pin carrier, lock pin, knob etc., it is characterized in that: the lock pin carrier connects with lock pin is movable, spring is arranged therebetween, lock pin overcomes elastic force and can revolve to the knob direction and turn 90 degrees, and the corresponding lock pin of lock housing has a breach.

The utility model is taked above-mentioned structure, has following beneficial effect: because lock pin of the present utility model and carrier have adopted movable connecting mode, rotatable 90 degree also fall in the breach of lock housing, thereby lock pin can overcome in the breach of elastic force retraction lock housing when bumping, can not cause the serious collision of lock pin and pin-and-hole box.When the utility model is locked a door, need spring into again in the pin-and-hole box thereafter by key with in lock pin carrier and the lock pin retraction lock housing, thereby the security performance height, avoided the serious collision of lock pin and pin-and-hole box simultaneously, and improved its application life.

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Fig. 1 is that the utility model lock pin connects figure with the lock pin carrier.

Fig. 2 is the utility model lock housing and lock pin constitutional diagram.

By Fig. 1, Fig. 2 as can be seen: the utility model comprises: lock pin 1, lock pin carrier 2, lock housing 3, knob 4.

As seen from Figure 1: lock pin 1 connects by screw 5 activities with lock pin carrier 2, and spring 6 is arranged on the screw 5, makes lock pin 1 need overcome elastic force when a sideway swivel.

As seen from Figure 2, corresponding lock pin 1 has a breach 7 on the lock housing 3, falls into wherein after lock pin 1 being revolved turn 90 degrees.

Claims (2)

1, a kind of door lock, comprise: lock housing (3), lock pin carrier (2), lock pin (1), knob (4) etc., it is characterized in that: lock pin carrier (2) connects with lock pin (1) is movable, spring (6) is arranged therebetween, lock pin (1) overcomes elastic force and can revolve to the knob direction and turn 90 degrees, and the corresponding lock pin of lock housing (3) (1) has a breach (7).

2, a kind of door lock according to claim 1 is characterized in that: lock pin (1) connects by screw (5) is movable with lock pin carrier (2), and spring (6) is arranged on the screw (5).
