Description

The slide door or window self-locking device

Technical field:

The utility model relates to lock technology field, is the self-locking device that a kind of slide door or window is used specifically.

Background technology:

At present, door and window generally adopts plug-type, and for safety, people install lock on slide door or window, but existing lock structure complexity, opening, locking needs key etc., very inconvenient, also has without key, but must be under the complete closing state of door and window, the ability manual locking, and security performance is bad, and locking at an arbitrary position can not be fixed.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of slide door or window self-locking device is provided, and mainly solves existing lock for sliding door and window complex structure, uses inconvenience, poor safety performance, the problem that can not lock at an arbitrary position.

In order to achieve the above object, the utility model is achieved in that the slide door or window self-locking device, it comprises lock body 1 and jam plate 8, its special character is that a side of described lock body 1 establishes cavity 14, in cavity 14, establish dead bolt 2, establish spring 3 on the dead bolt 2, on dead bolt 2, establish lifting appliance, on lock body 1, establish guide rail hole 7; Establish shrinkage pool 9 on the jam plate 8, shrinkage pool 9 is complementary with the tooth of dead bolt 2 lower ends.

Slide door or window self-locking device of the present utility model, tooth one side of its described dead bolt 2 lower ends is a straight flange, opposite side is a circular arc; Described lock body 1 opposite side has certain thickness, is a groove 10 between the both sides, and lifting appliance is for establishing axle 5 on the groove 10 of lock body 1, and cross bar 4 one ends pass axle 5 and are connected with dead bolt 2, and the other end of cross bar 4 is connected with depression bar 6; Described lifting appliance also can be in the position of lock body 1 corresponding dead bolt 2 and opens a hole 11, establishes a pull bar 12 by hole 11 on dead bolt 2; Described lifting appliance also can be and establish a knob 13 on lock body 1, and knob 13 is connected with dead bolt 2 by bar.

Compared with the prior art slide door or window self-locking device described in the utility model has following good effect: 1, since the tooth of dead bolt lower end be complementary with the shrinkage pool of jam plate, when dead bolt lower end insertion shrinkage pool, can be at an arbitrary position with the door and window automatic locking; 2, behind the door and window automatic locking, two fan door and windows can not unload or open from the open air; 3, simple in structure, easy to use; 4, can partly substitute safety grid.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model slide door or window self-locking device in detail.

Embodiment 1, referring to Fig. 1,2,3,4, be processed into lock body 1, one side of lock body 1 is the quadrangle of an opening, certain thickness is arranged, be processed into cavity 14 in the another side of lock body 1, between the both sides groove 10, the movable dead bolt 2 of installing in cavity 14, it is straight flange that the tooth of the lower end of dead bolt 2 is processed into a side, opposite side is a circular arc, mounting spring 3 on dead bolt 2, on dead bolt 2 lifting appliance are installed again, and lifting appliance is a fixed installation axle 5 on the groove 10 of lock body 1, cross bar 4 one ends are connected with dead bolt 2 by axle 5, and the other end of cross bar 4 is connected with depression bar 6; Offer guide rail hole 7 in lock body 1 bottom, be used for sliding on the slide rail of the bottom of slide door or window, lock body 1 is installed in the left side of the interior wing of slide door or window, the cavity of its tongue 2 with lock is installed between the two fan door and windows; Be processed into jam plate 8, be processed with shrinkage pool 9 equably on jam plate 8, shrinkage pool 9 is a plurality of, and shrinkage pool 9 is complementary with the tooth of dead bolt 2 lower ends, and jam plate 8 is installed in slide door or window exterior wing bottom inside, and the interior wing door and window can slide on jam plate 8.

Embodiment 2, referring to Fig. 5, with embodiment 1, difference is the cavity 14 of a side of lock body 1 for installation dead bolt 2, opposite side can be close to the left side of the interior wing of slide door or window, also certain clearance can be arranged, the lifting appliance of installing on the dead bolt 2 is established a pull bar 12 by hole 11 for to open a hole 11 in the position of lock body 1 corresponding dead bolt 2 on dead bolt 2.

Embodiment 3, referring to Fig. 6, with embodiment 1, difference be the lifting appliance installed on the dead bolt 2 on lock body 1, to establish a knob 13, knob 13 is connected with dead bolt 2 by bar.

Slide door or window self-locking device described in the utility model during use, when adopting the lifting appliance of embodiment 1, depression bar with hand, and under the effect of cross bar, dead bolt is raised; When adopting the lifting appliance of embodiment 2, the raising rod that makes progress, pull bar upwards moves in the hole, and dead bolt is raised immediately; When adopting the lifting appliance of embodiment 3, rotation knob, knob drive on the dead bolt by bar and carry; Thereby slide door or window freely, when unclamping hand, dead bolt moves down under the effect of spring force automatically, this moment, the dedentition of dead bolt bottom was gone in the shrinkage pool corresponding on the jam plate, thereby with the slide door or window automatic locking, can be at an arbitrary position with its automatic locking, two fan door and windows can not unload from the outside behind the automatic locking, and security performance is good.
