Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The perspective exploded view of Fig. 1 locking device one of the present utility model detailed description of the invention.
Detailed description of the invention
Be described in detail to the technical scheme in the utility model embodiment below, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
As shown in Figure 1, locking device 100 of the present utility model is installed in refrigerator door, thus, be conducive to saving space, be particularly useful for multi-door refrigerator, the gap between a body can be reduced, and the grade of outward appearance can be promoted.
Locking device 100 comprises: spring 10, mobile engagement with cams 20, fixed engagement cam 30 and fixed axis 40.
Spring 10 one end keeps axial restraint, and the other end and mobile engagement with cams 20 lean.Thus one end of spring 10 keeps fixing in position in the axial direction, and the other end can stretch with the motion of mobile engagement with cams 20.By using, spring 10 is flexible eliminates a play for body above-below direction, makes the rotation of held stationary in a body switching process.In addition, by selecting the spring of larger coefficient of elasticity can realize larger coupling mechanism force, switch gate coupling mechanism force is not by the impact of door body weight.
Further, the Men Tizhong of refrigerator has installation cavity 200, and spring 10, mobile engagement with cams 20, fixed engagement cam 30 and fixed axis 40 are arranged in this installation cavity 200.Meanwhile, the one end of installing cavity 200 is provided with shell blanking cover 50, and one end and the shell blanking cover 50 of spring 10 lean, and keep axial location to fix.Preferably, shell blanking cover 50 is fixed on the one end of installing cavity by trip bolt 60.
Mobile engagement with cams 20 can match with fixed engagement cam 30, and the mating surface of the two is arcwall face, and mobile engagement with cams 20 keeps being synchronized with the movement with refrigerator door.Meanwhile, fixed engagement cam 30 is fixedly connected with the hinge 300 of refrigerator door by fixed axis 40.
To achieve these goals, the madial wall installing cavity 200 offers mounting groove, and the sidewall of mobile engagement with cams 20 is provided with installs protruding 21, and mobile engagement with cams 20 is slided by installation protruding 21 and is arranged in mounting groove.Setting like this, is mounted opposite cavity, and mobile engagement with cams 20 can be slided in the axial direction, and in radial directions, does not produce displacement.Thus when refrigerator door is opened, mobile engagement with cams 20 can with refrigerator door generation synchronous axial system.
In addition, the mating surface of mobile engagement with cams 20 has arc-shaped recess, fixed engagement cam 30 mating surface has arc convex, and arc-shaped recess can match with arc convex.Preferably, the quantity of arc-shaped recess and arc convex is respectively two, and two arc-shaped recess positions are relative.
The two ends of fixed axis 40 form link 41, and two ends link 41 inserts in the hinge 300 of fixed engagement cam 30 and refrigerator door respectively, the plane that the side of link 41 comprises arcwall face and is connected with arcwall face.So, link limits the rotary motion of fixed engagement cam 30, and when refrigerator door is opened, fixed engagement cam 30 can keep fixing with hinge 300.
Thus when refrigerator door is opened, because fixed engagement cam 30 position keeps fixing, mobile engagement with cams 20 keeps being synchronized with the movement with refrigerator door, and mobile engagement with cams 20 produces pivoting friction with fixed engagement cam 30.Meanwhile, the mating surface due to the two is arcwall face, and mobile engagement with cams 20 is by the displacement that produces along mating surface upwards and Compress Spring 10.When reaching certain angle, two cams only rotate, and no longer produce displacement upwards, and spring 10 is in compression stable state.
Further, when refrigerator door close the door reach certain angle time, because spring 10 is in compressive state, under the effect of spring 10 elastic force, mobile engagement with cams 20 moves down, and can produce the component of rotation direction, accelerates to close the door, until refrigerator door is closed and produced coupling mechanism force, now move engagement with cams 20 and be again combined together with fixed engagement cam 30.
In sum, locking device of the present utility model is installed on refrigerator door inside, saves space, is particularly useful for multi-door refrigerator, can reduces the gap between a body, be conducive to the lifting of appearance.In addition, by using telescopic spring to eliminate a play for body above-below direction, the rotation of held stationary in a body switching process is made.In addition, by selecting the spring of larger coefficient of elasticity can realize larger coupling mechanism force, switch gate coupling mechanism force is not by the impact of door body weight.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
