Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

A kind of lock body, comprise lock case 9 and be arranged on latch bolt assembly 1 in lock case, latch bolt flap 2, push pedal 3, generous tongue assembly 4, generous tongue shift fork 5, square shaft turn-take 6, square shaft drive block 7, back-moving spring 8 forms; Latch bolt assembly comprises latch bolt 12, interior latch bolt 11, stage clip 13, limiting plate 14; Generous tongue assembly 4 comprises generous tongue 41, drag hook 42, locks and turn-take 43.Generous tongue shift fork 5 there is the first projection 21, generous tongue 41 has the first limit sliding chutes 22 and the second limit sliding chutes 24; Generous tongue shift fork rotates around its central axis 23, is slided in the first limit sliding chutes 22 by the first projection 21, drives the flexible of generous tongue.Generous tongue 41 there is the second projection 25, drag hook has the 3rd limit sliding chutes 26, drag hook has straight-tooth 27, lock upper Cylinder Gear 28 of turn-taking; Second projection 25 embeds in limit sliding chutes 26, can be slided in the 3rd limit sliding chutes 26 by the second projection 25 when generous tongue moves, drive the flexible of drag hook, straight-tooth 27 on drag hook engages each other with Cylinder Gear 28, make to lock and turn-take around its central axis rotation, lock realization of turn-taking and stretch out and take in.

Shown in Fig. 1, Fig. 2 (door opening state), when square shaft turn-take 6 by external force rotate clockwise time, the third gear limit (63) that square shaft is turn-taked promotes square shaft drive block 7 and rotates clockwise around its central axis, gear 71 on square shaft drive block engages each other with generous tongue shift fork gear 51, generous tongue is dialled and counterclockwise rotates around its central axis 23; Slided in the first limit sliding chutes 22 by the first projection 21 of generous tongue shift fork, drive the retraction of generous tongue; Generous tongue 41 has the second projection 25, drag hook has the 3rd limit sliding chutes 26(Fig. 5, Fig. 6), drag hook there is straight-tooth 27, lock upper Cylinder Gear 28 of turn-taking; Second projection 25 embeds in limit sliding chutes 26, can be slided in the 3rd limit sliding chutes 26 by the second projection 25 when generous tongue moves, drive the retraction of drag hook, straight-tooth 27 on drag hook engages each other with Cylinder Gear 28, make to lock and turn-take around its central axis rotation, lock and turn-take in retraction lock case.

When square shaft turn-take 6 rotate clockwise by external force time, square shaft turn-take on the first rib (61) promote push pedal and move up, push pedal promotes latch bolt flap 2 and rotates clockwise around its central axis, draws in latch bolt assembly; Thus realize the object of enabling.

Shown in Fig. 3, Fig. 4 (state of locking a door), when square shaft turn-take 6 by external force upwards rotate counterclockwise time, the second rib (62) that square shaft is turn-taked promotes square shaft drive block 7 and rotates counterclockwise around its central axis, gear 71 on square shaft drive block engages each other with generous tongue shift fork gear 51, generous tongue is dialled and rotates around its central axis 23 clockwise direction; Slided in the first limit sliding chutes 22 by the first projection 21 of generous tongue shift fork, drive stretching out of generous tongue; Generous tongue 41 has the second projection 25, drag hook has the 3rd limit sliding chutes 26(Fig. 5, Fig. 6), drag hook there is straight-tooth 27, lock upper Cylinder Gear 28 of turn-taking; Second projection 25 embeds in limit sliding chutes 26, can be slided in the 3rd limit sliding chutes 26 by the second projection 25 when generous tongue moves, drive stretching out of drag hook, straight-tooth 27 on drag hook engages each other with Cylinder Gear 28, make to lock and turn-take around its central axis rotation, locking turn-takes stretches out outside lock case; Thus the object that realization is locked a door.

Shown in Fig. 5, Fig. 6 (state of locking a door), the rear elevation of the front view that generous tongue assembly is retracted, illustrates on generous tongue 41 and has the second projection 25, drag hook has the 3rd limit sliding chutes 26, drag hook has straight-tooth 27, lock upper Cylinder Gear 28 of turn-taking; Second projection 25 embeds in limit sliding chutes 26, and the straight-tooth 27 on drag hook engages each other with Cylinder Gear 28.

Shown in Fig. 7 (state of locking a door), when square shaft turn-take 6 power disappear time, latch bolt assembly 1, by the elastic force effect of self latch bolt spring 13, spring back to the state ejecting lock case outside, and generous tongue remains on the state of indentation lock case inside.

Shown in the sectional view of K-K shown in Fig. 8, generous tongue shift fork 5 has first store oil groove A, second and store oil groove B, second and store oil groove C, more than store savings lubrication oil in oil groove, lubrication oil effect is the friction that reduces between part and increases the application life of lock body.
