Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Embodiment
Embodiment is as a kind of new design of draw-bar box, the system run into for specific crowd during use
Row problem, sufficient thinking is done with setting in the occupation mode of varying environment and the Structure Designing Problem of draw-bar box to draw-bar box
Meter, the purpose for meeting modern society's theme such as hommization, efficient, safety is reached.
A kind of Multifucntional draw-bar box, such as Fig. 1 and Fig. 2, including casing 1, the top of casing 1 is provided with pull bar 2, casing 1
Bottom be provided with away wheel 3, in addition to damping crawler component 4 and rotary switch, rotary switch is movably connected in the sidepiece of casing 1,
Rotary switch 5 includes rotating part 51 and screens portion 52, and screens portion 52 is connected to the end of rotating part 51, and the sidepiece of casing 1 is provided with
More than one damping crawler component 4, such as Fig. 7, casing 1 is provided with the folding groove 6 for being used for accommodating damping crawler component 4, and damping is climbed
Row component 4 includes support frame 41, rear baffle 42, cylinder 43, the first spring 44, second spring 45, connector 46 and some rollers
47, one end of support frame 41 is flexibly connected the inner side of folding groove 6, and the other end of support frame 41 is provided with crawling wheel 48, rear baffle 42
The bottom of folding groove 6, one end connection support frame 41 of cylinder 43 are fixed on, the other end of cylinder 43 connects through the first spring 44
On rear baffle 42, rear baffle 42 is provided with some connectors 46, and roller 47 is movably connected in one end of connector 46, connector 46
The other end is through second spring 45 and is connected on rear baffle 42, and support frame 41 is provided with some through holes passed through for roller 47
49。
This kind of Multifucntional draw-bar box, it is simple efficient by setting damping crawler component 4, complicated landform can be realized
Such as the walking of stair, step freely, save trouble and labor.While can walking freely in the plane, the tune of the height of pull bar 2 is realized
Section.By setting second spring 45, the damping of pair roller 47 is realized.By setting the first spring 44 and cylinder 43, realize to branch
The resilient support of support 41.
Compared with existing pull bar 2 casees, the Novel pull rod 2 casees of embodiment easily facilitates a variety of use demands of people, addition
Support frame 41, elastic roller 47, the structure design of elastic neck and rotary switch so that pull bar 2 casees not only makes on level land
With free and relaxed, and stair using when saved many troubles.As shown in fig. 7, support frame 41 is connected by axle with casing 1,
It is connected to an outer cylinder 43 around second spring 45 simultaneously in-between so that support frame 41 can slowly be opened around axle.Bottom
Roller 47 realize support frame 41 and can be slided in the state of Unscrew together with casing 1.The place on 41 preceding surface of support frame
Reason also cause itself in the closed state, elastic roller 47 be enough it is exposed.Elastic roller 47 into arranging device on rear baffle 42, rear portion
Second spring 45 cause the resilient enough of roller 47.
Damping crawler component 4 also includes pressing ereisma, is located at by ereisma between support frame 41 and rear baffle 42, after being located at by ereisma
On baffle plate 42, support frame 41 is provided with iron plate, and iron plate by ereisma with being correspondingly arranged.Rear baffle 42 is respectively arranged on by ereisma and cylinder 43
Both ends.By ereisma as shown in fig. 6, making it block or eject by pressing support frame 41.
Damping crawler component 4 also includes elastic neck 410 and inclined-plane shell fragment 411, and elastic neck 410 is located at support frame 41
Sidepiece, inclined-plane shell fragment 411410 are correspondingly arranged located at the inwall of folding groove 6 and with elastic neck 410, inclined-plane shell fragment 411410 and branch
Bottom spring is provided between support 41.The height of elastic bevel surface gradually increases setting to bottom land from the notch of folding groove 6.
In embodiment, the locking of support frame 41 is by being arranged on the inclined-plane shell fragment 411410 of the inwall of folding groove 6 corresponding thereto
The collective effect of elastic neck 410 for being arranged on the sidepiece of support frame 41 is realized.As shown in fig. 6, under released state, the support frame of locking
41 by external force when inwardly being promoted, and inclined-plane shell fragment 411410 inwardly extrudes in ramp effect lower stress, is separated with elastic neck 410,
Support frame 41 after unblock obtains certain speed in the presence of by ereisma, is able to quick to open；And lock support frame 41 is former
Reason is same as above.
The both sides of casing 1 are respectively equipped with folding groove 6, damping crawler component 4 are respectively equipped with folding groove 6, rotary switch is set
Between two folding grooves 6.Rotating part 51 uses disc, and the both sides of rotating part 51 are respectively equipped with screens portion 52, screens portion 52
Using square or semicircle.Rotary switch is as shown in fig. 7, rotate the switching for realizing rotary switch around jackshaft.
The Novel pull rod 2 casees no matter on level land or on stair using user can be allowed free and relaxed.Make when on level land
Used time, unfolding mode is as shown in figure 5, pin steps on rotary switch, then gently presses lower bracing frame 41, and support frame 41 ejects, in vapour
Slowly opened in the presence of cylinder 43.As shown in figure 3, connected between support frame 41 and casing 1 outside one around second spring 45
Cylinder 43, so as to not only enable support frame 41 slowly to open, and second spring 45 and the perfect adaptation of cylinder 43 cause case
The height that body 1 can be adapted from main regulation and hand, so as to reach the target of anticipation.When in stair in use, as shown in figure 4,
The characteristics of being used with reference to user, rows of elastic roller 47 not only enables casing 1 to be slided in staircase, and elastic roller 47
Impact is effectively buffered, so as to effectively solve the problems, such as 2 casees stair climbings of pull bar.
