Handle
Technical field
The present invention relates to a kind of handle, relate in particular to a kind of with self-return and with the handle of pooling feature.
Background technology
Existing handle is no matter be the handle on safety rail or the door on handle or the automobile on case and bag, for attractive in appearance and do not take up space, in the time not using, all need on fixing laminating case and bag or laminating automobile sidewall or door-plate, this just needs handle band self-return joint function, the existing handgrips with self-return joint function is all comparatively complicated, and for the function that coordinates self-return laminating also can be equipped with damping buffering function, make handle in the time of self-return, can not make handle pound energetically on case and bag or automobile sidewall or door-plate, the existing handgrips with this damping buffering function is very complicated, and the handle that some damping force is larger exists the defect of return completely, the too small DeGrain of buffering of damping force, can not meet consumer's needs.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, return is effective, damping buffering is effective handle.
For achieving the above object, the technology of the present invention solution is such: a kind of handle, comprise handle and handle set, handle, at its lower end is provided with joint pin, handle set is provided with adapter sleeve, joint pin matches with adapter sleeve and realizes handle, at its lower end and handle set is rotatably connected, the joint pin of handle is provided with returning spring, described returning spring is between handle joint pin and handle set adapter sleeve, and returning spring provides the elastic force of handle laminating return, between the opposite side of handle joint pin and handle set adapter sleeve, be provided with damping sleeve, between described damping sleeve and joint pin, be provided with damping grease, damping sleeve is provided with locating piece, adapter sleeve is provided with locating slot, the locating piece of damping sleeve matches with the locating slot of adapter sleeve, damping sleeve is provided with breach, it is consistent that the rotation direction of the corresponding gap position of joint pin when pull-up handle and breach open the direction that change is large.
In above-mentioned technical solution, handle was rotatably connected on handle set by joint pin and coordinating of adapter sleeve, between handle joint pin and handle set adapter sleeve, be provided with the returning spring that handle laminating return elastic force is provided, between handle joint pin and handle set adapter sleeve, be also provided with damping sleeve, and be provided with damping grease between damping sleeve and joint pin, such structure is in the process of pull-up handle handle, the joint pin of handle sways, overcome the elastic force of returning spring, also to overcome the damping frictional force of damping sleeve to joint pin simultaneously, while using other existing damping structure, so just need to overcome larger active force, pull-up handle handle is comparatively painstaking, but in damping structure provided by the present invention, because being provided with the locating slot that locating piece is provided with adapter sleeve, damping sleeve matches, the locating piece of damping sleeve is fixed in locating slot, damping sleeve is provided with breach, the ring wall of damping sleeve is not connected end to end, and it is consistent that the rotation direction of the corresponding gap position of joint pin when pull-up handle and breach open the direction that change is large, like this in the time of pull-up handle handle, handle joint pin sways, produce damping friction by damping grease and damping sleeve, the rotation that the effect that the breach of damping sleeve is rubbed by damping is connected post drives to open and becomes large, and open in the process that becomes large at breach, the diameter of damping sleeve is becoming large, make the space between damping sleeve and joint pin become large, pressure diminishes, thereby damping sleeve is diminished to the damping frictional reaction of joint pin, pull-up handle handle just compares better easily, when be pulled up the released return of handle handle time, the handle return of fitting under the effect of returning spring, in this process, in the time that handle place is released, the restoring force of returning spring is maximum, can be with fixed handle peak acceleration to laminating position return, the direction deformation that now damping sleeve dwindles towards breach under the effect of the damping frictional force of joint pin, the diameter of damping sleeve is also along with diminishing, space between damping sleeve and joint pin is diminished, it is large that pressure becomes, make damping sleeve become large to the damping frictional reaction of joint pin, and damping frictional force is now the maximum in whole laminating return process, along with the process of laminating return, the restoring force of returning spring diminishes gradually, acceleration with fixed handle laminating return is also diminishing gradually, the pressure that the deformation of same damping sleeve packs tightly connection also diminishes gradually, the final handle return of comparatively mildly fitting that guarantees, therefore handle provided by the invention has simple in structure, return is effective, the feature that damping buffering is effective.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Fig. 9, specific embodiment provided by the invention, a kind of handle, comprise handle 1 and handle set 2, handle 1 lower end is provided with joint pin 1-1, handle set 2 is provided with adapter sleeve 2-1, joint pin 1-1 matches with adapter sleeve 2-1 and realizes handle 1 lower end and handle set 2 is rotatably connected, it is characterized in that: the joint pin 1-1 of handle 1 is provided with returning spring 3, described returning spring 3 is between handle 1 joint pin 1-1 and handle set 2 adapter sleeve 2-1, and the elastic force that returning spring 3 provides handle 1 to fit return, between the opposite side of handle 1 joint pin 1-1 and handle set 2 adapter sleeve 2-1, be provided with damping sleeve 4, between described damping sleeve 4 and joint pin 1-1, be provided with damping grease, damping sleeve 4 is provided with locating piece 4-1, adapter sleeve 2-1 is provided with locating slot 5, the locating piece 4-1 of damping sleeve 4 matches with the locating slot 5 of adapter sleeve 2-1, damping sleeve 4 is provided with breach 4-2, it is consistent that the rotation direction of the corresponding breach 4-2 of joint pin 1-1 when pull-up handle 1 position and breach 4-2 open the direction that change is large, this handle can be used for case handle, automotive safety handrail, the fields such as catch can reach same effect.
As shown in Figure 3, described returning spring 3 and damping sleeve 4 lay respectively at the outside of two joint pin 1-1, such structure setting, can give the middle panel of handle reserved larger position, can be in use for user's finger leaves larger space, and decreased food need not be made very long, if certainly described returning spring 3 and damping sleeve 4 are positioned to the inside and outside both sides of same joint pin 1-1, such structure can be in installation process, while only needing a joint pin 1-1 of mounting handle, just damping sleeve 4 can be installed together with returning spring, can reach equally object of the present invention.
As shown in Fig. 3, Fig. 5, Fig. 7, Fig. 8, described damping sleeve 4 be circular rings nested structure, and locating piece 4-1 is positioned at a side end position of the breach 4-2 of damping sleeve 4, adopt circular rings nested structure, can make the damping friction between damping sleeve 4 and joint pin 1-1 the most even, pack tightly pressure also maximum, the effect of damping friction is best simultaneously.
