Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Forward and backward axle (8) ', (8) one ends have the cylindrical of open slot for middle, end is rectangular rectangular in cross section in addition.

Front hand grip (7) ' be the middle lengthy motion picture that through hole is arranged, back handle (7) is the middle lengthy motion picture that the waist hole is arranged, also respectively there is a flange at the two ends of top edge, and two circular arc cutaway are arranged on the lower limb.

Front and back panels (6) ', (6) be disc middle, that there are through hole, hanger in two ends, the edge of rear board (6) intermediate disc, the vertical insurance breach (9) that matches with back handle (7) one end boss in addition.

Turgor pressure spring (26) tightly embeds in the open slot in the middle of rear axle (8) one ends, cooperates with two circular arc cutaway on back handle (7) lower limb, prevents from that back handle (7) automatic shift is strayed into to insure breach (9).

Front handlebar assembly (10) passes front panel (6) by band front hand grip (7) ' front axle (8) ' ' intermediate throughholes, connect into whole formation with collar, bearing pin.

Back handle assembly (11) passes rear board (6) intermediate throughholes by the rear axle (8) of band back handle (7) and turgor pressure spring (26), connects into whole formation with collar, bearing pin.

Lock housing (3) is a box-like, and perpendicular bearing, column, fixed leg, slide rod sleeve (15) are arranged on the bottom surface, and junction button is arranged on the edge.

The through hole and the breach that cooperate with fixed leg, reference column etc. on the lock housing (3) are arranged on the locking closure (4).

Lock body assembly (1) is connected by lock housing (3) spot welding or screw that dead bolt assembly (2), touching lever contact (12), pusher dog (16) are installed on the door lock plate that through hole, groove are arranged on the side and the side, again the integral body that is connected, fits in locking closure (4).

Fixed cover (5) is the middle hexagon long tube that inner bolt hole is arranged.

Pusher dog (16) has the cylindrical of square hole for middle, and two pusher dogs that stretch out are arranged on the periphery at one end.

Following bolt plate (20) has waist hole and projection (24) for the centre, and two edges have the tongue hook (25) of protrusion, recessed pusher dog groove, the vertical spring limited block of bending respectively.

Slip dead bolt (23) has through hole on being, and the monolateral polygon plain film that two projected claws parallel to each other are arranged.

Dead bolt assembly (2) is held two symmetry and the persons of being close to by bearing pin with therebetween

The slip dead bolt (23) of shape latch bolt spring (22) connects into whole formation with upper and lower bolt plate (21), (20).

And making circular arc inwall in the middle of the latch bolt spring (22) be close to projection (24) on the bolt plate (20) down, upper/lower terminal is close to upper and lower bolt plate (21), (20).

Touching lever (18) two ends are cylindrical, and middle is the rectangle that has through hole, and a termination is spherical.

Lock dog (19) has waist hole, through hole on being, there is the plate shape of arc hook at the edge.

Touching lever contact (12) is connected whole the composition by touching lever (18) that is connected with spring (17), packing ring and lock dog (19).

At first the lock body assembly (1) that assembles is put into sliding door edge edge intermediate groove, again forward and backward handle assembly (10), (11) are screwed on the inside and outside surface of moving door by the fixed cover (5) that is clamped in therebetween, and make forward and backward axle (8) on it ', (8) respectively the square opening in the middle of pusher dog (16) is tightly inserted at two ends, fixedly connected being integral is as Fig. 1, Fig. 2, shown in Figure 3.

During use, rotate front or rear handle (7 '), (7) with hand, connected pusher dog (16) is rotated, thereby the following bolt plate (20) that drives on the dead bolt assembly (2) moves toward interior along slide rod sleeve (15), and it is fixing that tongue hook (25) on it is buckled in the arc hook of lock dog (19).Rotate an angle when simultaneously two slip dead bolts (23) are by lockhole and get back in the same plane in line, then door is opened as shown in Figure 5.

If will close the door, as long as pulling moves door, after lockplate (13) on touching lever contact (12) and the doorframe on it is touched, touching lever (18) moves backward and drives connected lock dog (19) and rotates an angle, make it break away from tongue hook (25), under the effect of big spring (14), latch bolt spring (22), dead bolt assembly (2) ejects automatically, be locked in the tongue hole on the lockplate (13), two slip dead bolts (23) rotate an angle simultaneously, flick outside upper and lower jam plate (21), (20), as shown in Figure 4.

After the people enters the room, with back handle (7) backward insurance breach (9) direction on the panel (6) promote, flange on the back handle (7) just is embedded in the insurance institution that constitutes in the insurance breach (9), make latch by snap close, if the outdoor people of having rotates front hand grip (7 '), just can't rotate at this moment outdoor can't unblanking, have only indoor people earlier back handle (7) to be decorporated from insurance breach (9), and then rotate back handle (7) and lock could be opened.

The utility model is compared with prior art: this latch does not need key, as long as handle just can be opened lock before or after rotating, needs only simultaneously and touches gently that the touching lever contact just can close locking, has reduced the trouble of carrying key, and is easy to use, rapid.In addition in the back on the plate also design insurance institution is arranged, back handle is moved on the safety position, outdoor people just can't open lock, can only be unblanked by indoor people.And the dead bolt assembly is a fabricated structure, constitute by clamping slip dead bolt between upper and lower bolt plate, move the door lock after, the slip dead bolt rotates, flicks, upholds upper and lower bolt plate outer locking, increased the area of dead bolt, use saferly, reliable, provide a kind of novel structure, latch easy to use again for market simultaneously.
