Description

Case handle

Technical field

The utility model relates to a kind of mechanism of handgrip, specifically a kind of handle that is applied to case and bag.

Background technology

It is closure state that existing case handle design can realize greatly handgrip non-working condition, when using, handgrip can turn an angle, be convenient for people to use, after use finishes, handgrip is got back to closure state automatically, and so handgrip can not have influence on the facility that people use case and bag because of having occupied certain space.Realizing this functional compartments handgrip design is all to utilize the elastic potential energy of spring to realize.In existing design, between handgrip and handle bracket, by projection, be rotatably connected, spring fitting is at the outer surface of projection, both ends of the spring is separately fixed on handgrip and handle bracket, handgrip has had certain elastic potential energy at non-working condition (being exactly closure state), handle rotation, more increased the elastic potential energy of spring, after use finishes, handgrip is because closure state is got back in the elastic potential energy effect of spring automatically, this design has been undoubtedly, but because spring fitting is at the outer surface of axle, easily cause the two ends of spring because elastic potential energy is crossed strong and torsional deformation, the elastic failure that finally causes spring, in the time of this external mounting spring, in order to obtain an initial elastic potential energy, spring one end need to be fixed, the other end rotates to an angle to obtain elastic potential energy, owing to there is no position-limit mechanism, after rotating to an angle, need to use the lid that covers spring to block spring, then fast the lid that blocks spring is arranged on handle bracket, such installation is obviously inconvenient, to the operating technology of installing, require high, and need special-purpose equipment, when in use spring drops, consumer cannot install voluntarily, the elastic potential energy of initial increase spring is too small, cannot make handgrip automatically reset to closure state.

Summary of the invention

In order to overcome the weak point of background technology of the present utility model, the utility model provides a kind of spring to be not easy that distortion was lost efficacy, the case handle of easy for installation, stable connection.

The technical solution of the utility model is: the utility model provides a kind of case handle, comprise handgrip and handle bracket, handgrip two ends are provided with projection, handle bracket is provided with projection installing hole, projection is installed in rotation in projection installing hole, described projection is provided with spring mounting hole, in described spring mounting hole, spring is installed, one end that described spring inserts in spring mounting hole is provided with fixed bar, in handgrip projection, be provided with fixed mechanism, described fixed bar matches with fixed mechanism, and the fixed bar of spring is fixed in the spring mounting hole of projection, the other end of spring is provided with motion bar, projection installing hole inwall on described motion bar and handle bracket connects, described handgrip projection outside is provided with limited block, described limited block is corresponding with the motion bar position of spring, and the end face restraint bar that limited block matches with motion bar rotates towards this end face direction.

The beneficial effect of technique scheme is: spring mounting hole is set in projection and one end fixed bar of spring is fixed on the fixed mechanism in projection, again projection installing hole inwall on the other end of spring and handle bracket is connected, while making handle rotation, drive that one end of fixed bar of spring to rotate with handgrip, and the spring other end all the time with handle bracket on projection installing hole inwall connect, keep motionless, thereby reach spring self savings potential energy when unclamping handgrip, handgrip automatically replies, and at handgrip projection arranged outside limited block, and the end face restraint bar that limited block matches with motion bar rotates towards this end face direction, this structure can be when mounting spring, after the fixed bar of spring is fixed on fixed mechanism, manually motion bar is rotated to required angle, provide spring required elastic potential energy, and this elastic potential energy can provide handgrip to automatically reply, and when using handgrip, the process that handgrip is pulled up to use state from closure state is again the process that a potential energy increases, the elastic potential energy of spring is further increased, more can guarantee that handgrip automatically replies, and can according to personal like preset rotate motion bar around the number of turns, to reach the initial size of the elastic potential energy of spring, thereby directly have influence on dynamics and speed that handgrip automatically replies, in this process, after motion bar pitch of the laps tightens in advance, can be stuck on limited block, preventing that motion bar from not stressing automatically replies, thereby the elastic potential energy of spring is discharged, and this spring need to can not installed voluntarily and adjust voluntarily according to hobby by professional tool.

Further, the fixed bar of described spring is for to extend outward horizontal fixed bar along spring axial direction, described fixed mechanism is the locating hole matching with the fixed bar of described spring, this structure when mounted, the horizontal fixed bar of spring is inserted in locating hole, fix with handgrip, this connected mode is stable connection, reliable comparatively.

Further, the fixed bar of described spring is for to extend outward horizontal fixed bar along spring axial direction, described fixed mechanism is the locating slot matching with the fixed bar of described spring, this structure when mounted, the horizontal fixed bar of spring is inserted in locating slot, and when rotation motion bar adds elastic potential energy in advance, laterally fixed bar will finally be against on one end sidewall of locating slot, finally realize spring and handgrip fixes, the comparatively same stable connection of this connected mode, reliably, and install more for convenience, be that locating slot is wider, laterally fixed bar can insert in locating slot comparatively easily.

Further, the fixed bar of described spring is for to extend outward horizontal fixed bar along spring axial direction, described fixed mechanism is the locating piece matching with the fixed bar of described spring, this structure when mounted, spring is packed in spring mounting hole, and when rotation motion bar adds elastic potential energy in advance, laterally fixed bar will finally be against on locating piece, finally realize spring and handgrip fixes, the comparatively same stable connection of this connected mode, reliably, and install more convenient, be that spring can pack in spring mounting hole more conveniently, and horizontal fixed bar can be matched with locating piece.

Further, the motion bar of described spring is provided with the extension rod perpendicular with motion bar, the axis of described extension rod parallels with the axis of spring, the axial lateral surface of extension rod and the projection installing hole inwall on handle bracket connect, this structure at motion bar when projection installing hole inwall on handle bracket matches, can increase the area that coordinates contact, stressed more balance, the axial direction of the extension rod simultaneously paralleling with axle of spring is perpendicular with the release direction of the elastic potential energy of spring, the lateral surface and the projection installing hole inwall that are extension rod length direction connect, and formation interaction force, this interaction force is at the lateral surface of the length direction of whole extension rod, compare with traditional mode of going butt projection installing hole inwall to form some cooperation with spring end, this mode is more reliable, can there is not the phenomenon that spring end snaps in the projection installing hole inwall of plastic material.

Further, in the spring mounting hole of described handgrip, be provided with outward extending fixed leg, described spring housing fixed leg outside, this structure can be so that spring inner ring matches with fixed leg, match with spring mounting hole in the outer ring of spring, thereby reach the reliable effect of spring fitting, can also effectively prevent the oblique compression of spring, thereby impact is used simultaneously.
