Detailed description of the invention

Referring to figs. 1 through Fig. 6, the suppressible door lock embodiment of a kind of handle 2 of the utility model is described further.

As shown in Figures 1 to 6, the suppressible door lock of a kind of handle 2, comprise grille main body 1, trundle 4, lock core 3 and handle 2, it is characterized in that: described grille main body 1 is provided with cavity, described cavity is identical with the shape of handle 2, described handle 2 comprises head and bottom, described head is the part that handle 2 is placed in outside grille main body 1, described bottom is the part that handle 2 is placed in grille main body 1, bottom is provided with spring 7 groove and driving hole, described driving hole inwall and the laminating of trundle 4 external surface, described handle 2 is provided with stretching structure, described stretching structure comprises holder 5, spring 7, guide groove 9, slide block 8 and chute 10, described holder 5 is fixed in cavity by bolt 6, described spring 7 is positioned at spring 7 groove, described chute 10 is positioned at trundle 4 surface, described guide groove 9 is positioned at driving hole inner surface, described slide block 8 is embedded in chute 10.

Grille main body 1 is opened the cavity identical with handle 2 shape, can handle 2 be embedded in grille main body 1, prevent external force from touching the damage caused handle 2, play the effect of shutter handle 2, handle 2 is embedded in grille main body 1 simultaneously, can guarantor can not be collided by handle 2 during activity near door, and damage, and handle 2 is provided with stretching structure, can well be convenient for people to use handle 2, only need switch the retraction of handle 2 by pressing pressure and stretch out state, when handle 2 be in stretch out state time, press pressure once to loose one's grip afterwards, handle 2 enters retracted mode, press pressure more once to loose one's grip afterwards, handle 2 gets back to the state of stretching out again, reciprocal with this, realize the quick flexible of handle 2, easy to use, easy and simple to handle, also protect user while protection handle 2 is not damaged not to be subject to handle 2 and to injure.

Wherein, described slide block 8 comprises bottom slide block 8 and columnar projections 82, and be embedded at bottom described slide block 8 in chute 10, described columnar projections 82 is embedded in guide groove 9, and described guide groove 9 is provided with self-locking structure.

Columnar projections 82 is utilized to be connected with guide groove 9, be connected with chute 10 bottom slide block 8, indirectly guide groove 9 and chute 10 are connect, utilize square pin as trundle 4, first can ensure that trundle 4 not easily skids when torsion, make the power maximum using of torsion, square pin surface fits tightly with driving hole inwall simultaneously, slide block 8 is not easily deviate from, be conducive to slide block 8 and connect chute 10 and guide groove 9, two-way interaction is moved mutually, by the self-locking design that guide groove 9 is special, making handle 2 press pressure once stretches out outside grille main body 1, press pressure more once in retraction grille main body 1, realize the object of free-extension, operation is made to become easy, avoid handle 2 to be subject to external force and to touch and be damaged, it also avoid the injury that handle 2 couples of people of being exposed on the external cause.

The principle of guide groove 9 and chute 10 is further explained herein, described slide block 8 is positioned at chute 10, slide block 8 can reciprocate along chute 10, slide block 8 is provided with columnar protrusions, columnar protrusions is positioned at guide groove 9, when handle 2 is stressed be moved time, the direction of movement is direction, trundle 4 axle center 11, handle 2 drives the guide groove 9 on driving hole together to move, the movement of guide groove 9 has driven slide block 8 to move back and forth along chute 10, when handle 2 be in stretch out state time, slide block 8 is arranged in Fig. 6 and stretches out state position 91, when stressed the pressing of handle 2 is depressed into inner terminal, slide block 8 is in Fig. 6 and presses pressure position 92 for the first time, after loosing one's grip, slide block 8 enters Fig. 6 retracted mode position 93, now handle 2 is in retracted mode, when handle 2 again stressed pressing be depressed into inner terminal, slide block 8 enter Fig. 6 second time press pressure position 94, after loosing one's grip, under the active force of spring 7, handle 2 drives the guide groove 9 on driving hole inwall to move outward, and slide block 8 moves to stretching out state position 91 by pressing pressure position 94 for the second time, completes and once circulates.

Wherein, described holder 5 comprises base, sidewall and flange, and described base is fixed in cavity by bolt 6, and described sidewall is round tubular structure, and described bottom is provided with ring-type nib, described ring-type nib and flange inconsistent.

Utilize the inconsistent of flange and ring-type nib, handle 2 can not be deviate from when being in and stretching out state, the stretching structure of handle 2 is caused to damage, ensure the application life of door lock, because handle 2 often needs to press pressure and turn, axial force is received again while receiving radial load, easily cause the damage of stretching structure, bolt 6 is utilized to fix fixing for base with cavity, handle 2 is connected by stretching structure with holder 5, when damaging appears in the inner body of stretching structure, bolt 6 can be opened, holder 5 is together unloaded together with handle 2, the part of damage is changed, without the need to changing whole door lock, save material, convenient installation, improve again utilization rate and the life-span of door lock.

Wherein, described cavity is circular trough, described head is frustum cone structure, described bottom is hollow cylindrical structure, the diameter of described bottom is less than the diameter of head, when handle 2 embeds in circular trough, described head is provided with plane, and the surface of described plane and grille main body 1 is in same plane.

Handle 2 is designed to circle, the cavity area needed for handle 2 can be reduced to the full extent, save space simultaneously, simultaneously circular cavity is easy to processing, and be frustum cone structure by handle 2 head design, the inclined-plane of round platform is convex globoidal, make the shape of handle 2 head good, be easy to pinch and hold, meet the use habit of contemporary people, easy to use, embody human oriented design, when handle 2 is in retracted mode, the plane of head and the surface one of grille main body 1, make the appearance of product be no lack of sight.

The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
