Description
Technical field
The utility model belongs to draw-bar box field, particularly relates to a kind of handle of draw-bar box.
Background technology
Distance between existing draw-bar box handle and draw-bar box can not regulate, and is difficult to be suitable for the larger crowd of height differences, uses and has larger limitation.
Utility model content
The purpose of this utility model can not regulate for the distance between existing draw-bar box handle and draw-bar box to cause draw-bar box to use to have larger limitation and the height-adjustable draw-bar box handle of one provided.
The utility model is achieved by the following technical solution:
Height-adjustable draw-bar box handle, comprise handle, load-bearing band, load-bearing band runs through handle and arranges, load-bearing band one end is fixed on draw-bar box, also comprise the automatic contracting mechanism of a load-bearing band, the automatic contracting mechanism of load-bearing band is arranged on draw-bar box, the described automatic contracting mechanism of load-bearing band comprises automotive rolling mechanism and automatic locking mechanism for card, automotive rolling mechanism comprises clockwork spring, the fixed axis of fixing clockwork spring the inner, the winder that is connected with clockwork spring outer end, and the relative draw-bar box of winder is rotationally connected; Described automatic locking mechanism for card comprises shell, button, sliding shoe, back-moving spring, shell has the groove passed for load-bearing band, button runs through shell and arranges, the lower end of button contacts sliding shoe, sliding shoe and shell are slidably connected, one end of sliding shoe contacts back-moving spring, and the other end has dentalation, and dentalation contacts load-bearing band.
Sliding shoe has a baffle plate, and the rearward end of button contacts baffle plate.
Described handle is connected with load-bearing band relative sliding.
The beneficial effects of the utility model: arrange the automatic contracting mechanism that can regulate the spacing of handle and draw-bar box between the utility model load-bearing band and draw-bar box, make draw-bar box be applicable to more crowd, its limitation is less, practical.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model automatic locking mechanism for card.
Fig. 3 is the structural representation of automotive rolling mechanism of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1-Figure 3, height-adjustable draw-bar box handle, comprise handle 1, load-bearing band 2, load-bearing band 2 runs through handle 1 and arranges, load-bearing band 2 one end is fixed on draw-bar box, also comprise the automatic contracting mechanism of a load-bearing band, the automatic contracting mechanism of load-bearing band is arranged on draw-bar box, the described automatic contracting mechanism of load-bearing band comprises automotive rolling mechanism and automatic locking mechanism for card, automotive rolling mechanism comprises clockwork spring 3, the fixed axis 4 of fixing clockwork spring the inner, the winder 5 that is connected with clockwork spring outer end, and the relative draw-bar box of winder 5 is rotationally connected; Described automatic locking mechanism for card comprises shell 6, button 7, sliding shoe 8, back-moving spring 9, shell 6 has the groove 10 passed for load-bearing band 2, button 7 runs through shell 6 and arranges, the lower end of button 7 contacts sliding shoe 8, sliding shoe 8 and shell 6 are slidably connected, one end of sliding shoe 8 contacts back-moving spring 9, and the other end has dentalation, and dentalation contacts load-bearing band 2.Sliding shoe 8 has a baffle plate 11, and the rearward end of button 7 contacts baffle plate 11.Described handle 1 is connected with load-bearing band 2 relative sliding.
When needing the distance between adjusting yoke case and handle, first button is pressed, the dentalation of sliding shoe is made to depart from load-bearing band, load-bearing band is owing to losing the active force of sliding shoe rear end spring, make load-bearing band retractable, thus play regulating action, and load-bearing band is subject to the active force of clockwork spring all the time, makes load-bearing band have the function of automatically shrinking; Unclamp button when being adjusted to the height of needs between handle and draw-bar box, make back-moving spring contact sliding shoe, thus make the dentalation of sliding shoe one end contact load-bearing band, and limit load-bearing band and stretch up and down.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
