Description

Handle

Technical field

The present invention relates to a kind of handle, relate in particular to a kind of with self-return and have the handle of pooling feature.

Background technology

Existing handle is no matter be handle or the handle on safety rail on the automobile or the door on the case and bag; For attractive in appearance and do not take up space; All fixedly on applying case and bag or applying automobile sidewall or the door-plate, this just needs handle band self-return joint function when not using, and the handgrips of existing band self-return joint function is all comparatively complicated; And for the function that cooperates self-return to fit also can be equipped with the damping buffering function; Make handle that handle is pounded energetically on case and bag or automobile sidewall or door-plate, existing handgrips with this damping buffering function is very complicated, and the bigger handle of some damping force exists the defective of return fully; The too small then DeGrain of buffering of damping force can not satisfy consumer's needs.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, return is effective, damping buffering is effective handle.

For realizing above-mentioned purpose, technical solution of the present invention is such: a kind of handle comprises handle and handle set; Handle, at its lower end is provided with joint pin, and handle set is provided with adapter sleeve, and joint pin matches with adapter sleeve and realizes that handle, at its lower end and handle set are rotatably connected; The joint pin of handle is provided with returning spring; Said returning spring is between handle joint pin and handle set adapter sleeve, and returning spring provides the elastic force of handle applying return, is provided with the damping cover between the opposite side of handle joint pin and the handle set adapter sleeve; Be provided with damping grease between said damping cover and the joint pin; Damping puts and is provided with locating piece, and adapter sleeve is provided with locating slot, and the locating piece of damping cover matches with the locating slot of adapter sleeve; Damping is arranged with breach, and it is consistent that the rotation direction of the corresponding gap position of joint pin during the pull-up handle and breach open the big direction of change.

Because in the above-mentioned technical solution, handle was rotatably connected on the handle set through joint pin and cooperating of adapter sleeve, was provided with the returning spring that handle applying return elastic force is provided between handle joint pin and the handle set adapter sleeve; Also be provided with the damping cover between handle joint pin and the handle set adapter sleeve, and be provided with damping grease between damping cover and the joint pin, such structure is in the process of pull-up handle handle; The joint pin of handle sways, and overcomes the elastic force of returning spring, also will overcome the damping frictional force of damping cover to joint pin simultaneously; When using other existing damping structure, so just need overcome bigger active force, pull-up handle handle is comparatively painstaking; But in the damping structure provided by the present invention, because damping puts and is provided with locating piece and matches with the locating slot that adapter sleeve is provided with, the locating piece that damping is overlapped is fixed in the locating slot; Damping puts and is provided with breach; The ring wall of damping cover is not linked to each other end to end, and the rotation direction of the corresponding gap position of joint pin during the pull-up handle and breach to open the big direction of change consistent, like this when pull-up handle handle; The handle joint pin sways; Produce the damping friction through damping grease and damping cover, make the effect of breach through the damping friction of damping cover driven to open and become big, and open in the process that becomes big at breach by the rotation of joint pin; The diameter of damping cover is becoming big; Make space between damping cover and the joint pin become big, pressure and diminish, thereby make the damping cover diminish to the damping frictional reaction of joint pin, pull-up handle handle just compares better easily; When the released return of handle handle that is pulled up, handle is the applying return under the effect of returning spring, in this process; When the handle place was released, the restoring force of returning spring was a maximum, can drive the handle peak acceleration to applying position return; Damping this moment is enclosed within the direction deformation of dwindling towards breach under the damping function of friction of joint pin, and the diameter of damping cover makes that also along with diminishing the space between damping cover and the joint pin diminishes, pressure becomes big; Make the damping cover become big to the damping frictional reaction of joint pin; And the damping frictional force of this moment is the maximum in the whole applying return process, and along with the process of applying return, the restoring force of returning spring diminishes gradually; The acceleration that drives handle applying return is also diminishing gradually; The pressure that the deformation of same damping cover packs tightly connection also diminishes gradually, finally guarantees the handle return of comparatively mildly fitting, therefore handle provided by the invention have simple in structure, return is effective, the damping buffering good effectiveness.

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further description.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 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, and handle set 2 is provided with adapter sleeve 2-1; Joint pin 1-1 matches with adapter sleeve 2-1 and realizes that handle 1 lower end and handle set 2 are rotatably connected; It is characterized in that: the joint pin 1-1 of handle 1 is provided with returning spring 3, and said returning spring 3 is between handle 1 joint pin 1-1 and handle set 2 adapter sleeve 2-1, and returning spring 3 provides the elastic force of handle 1 applying return; Be provided with damping cover 4 between the opposite side of handle 1 joint pin 1-1 and the handle set 2 adapter sleeve 2-1; Be provided with damping grease between said damping cover 4 and the joint pin 1-1, damping cover 4 is provided with locating piece 4-1, and adapter sleeve 2-1 is provided with locating slot 5; The locating piece 4-1 of damping cover 4 matches with the locating slot 5 of adapter sleeve 2-1; Damping cover 4 is provided with breach 4-2, and it is consistent that the rotation direction of the corresponding breach 4-2 of the joint pin 1-1 during pull-up handle 1 position and breach 4-2 open the big direction of change, and this handle can be used for fields such as case and bag handle, automotive safety handrail, catch can both reach same effect.

As shown in Figure 3; Said returning spring 3 and damping cover 4 lay respectively at the outside of two joint pin 1-1, and such structure setting reserves bigger position can for the middle panel of handle; Can be in use leave bigger space for user's finger; And need not decreased food be made very longly, if certainly said returning spring 3 and damping cover 4 are positioned at the inside and outside both sides of same joint pin 1-1, such structure can be in installation process; Just can damping be overlapped 4 when only needing joint pin 1-1 of handle installation and install together, can reach the object of the invention equally with returning spring.

Like Fig. 3, Fig. 5, Fig. 7, shown in Figure 8; Said damping cover 4 be the circular rings nested structure; And locating piece 4-1 is positioned at the side end position of the breach 4-2 of damping cover 4, adopts the circular rings nested structure, can make the damping friction between damping cover 4 and the joint pin 1-1 the most even; It is also maximum to pack tightly pressure simultaneously, and the effect of damping friction is best.
