Description
Technical field
This utility model relates to a kind of luggage case, specifically a kind of pull bar brake type luggage case.
Background technology
The brake unit material of the most most of luggage cases mostly is plastics, adopt the brake pedal mode that tramps with one's feet and limit luggage wheel assembly rotation, when forgetting that the luggage wheel assembly of braking is released braking just tows, will damage producing bottom wheel, shorten the service life of luggage case.
Summary of the invention
For the problem overcoming prior art to exist, the purpose of this utility model is to provide a kind of pull bar brake type luggage case, and this luggage case pull-up telescopic lever can release braking, with drawing with walking, puts down pull bar and can realize braking, the safest, easy, efficiently.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pull bar brake type luggage case, including casing, is provided with fixing bar in casing, and connecting on fixing bar has telescopic upper end pull bar, it is characterised in that: being provided with roller and ratchet at box bottom, roller is fixing with ratchet to be connected, and has concentric rotating shafts；It is provided with brake bar at box bottom, is provided with the ratchet suitable with ratchet in the lower end of brake bar；Brake bar upper end is connected with braking rope, and the other end of braking rope is fixed on telescopic upper end pull bar after fixing bar, is provided with the pulley making braking rope change draw direction, is provided with scalable tape measure spring mechanism at braking rope in casing；Brake bar is set with spring.
Further, being externally provided with sleeve at brake bar, spring is positioned at sleeve, is provided with bearing between brake bar and sleeve.Sleeve is provided with oil filler point.
This utility model is provided with handle at telescopic upper end pull bar top, and braking rope is fixed on telescopic upper end pull bar and handle junction.In casing, the left and right sides is equipped with fixing bar, and both sides are equipped with braking rope in fixing bar.
This utility model has, at roller top, the stock that a ratchet stretches out, braking rope and stock are gone out head part fix, when needs pawl wheel, braking rope is kept to be in relaxation state, i.e. ratchet mechanism off position can (note: spring itself has elastic force, when making camber of spring without external force, extended make ratchet embedding ratchet two tooth between, owing to ratchet fixes with bonded with axle with luggage wheel assembly, therefore luggage wheel assembly can be realized and fix function)；When needs release braking, being pulled upwardly by braking rope, ratchet leaves ratchet, and luggage case recovers to rotate.
Wheel bar upper end has pouring orifice, bottom to have sealing ring (seeing figure in detail), and a little lubricating oil is injected pouring orifice, keeps spine bar normal with rack inner wall two ends lubrication, moves up and down during bar lighter.Ratchet mechanism belongs to intermittent motion mechanism, and the luggage wheel assembly size of neglecting greatly of this mechanism actual determines, i.e. mechanism's diameter is less than luggage wheel assembly diameter.
This utility model pull-up telescopic lever can release braking, with drawing with walking, puts down pull bar and can realize braking, the safest, easy, efficiently.

Fig. 2 is brake structure magnified partial view in lower end in this utility model.
Fig. 3 is reversible ratchet mechanism structural representation in this utility model.
Detailed description of the invention
A kind of pull bar brake type luggage case, including casing 20, is provided with fixing bar 12 in casing, and connecting on fixing bar has telescopic upper end pull bar 11.Being provided with roller 21 and ratchet 22 at box bottom, roller and ratchet have concentric rotating shafts 23, and roller is fixed with ratchet and is connected；It is provided with brake bar 24 at box bottom, is provided with the ratchet 25 suitable with ratchet in the lower end of brake bar；Brake bar upper end is connected with braking rope 3 by drag hook, and the other end of braking rope is fixed on telescopic upper end pull bar after fixing bar, is provided with the pulley making braking rope change draw direction, is provided with scalable tape measure spring mechanism 6 at braking rope in casing；Brake bar is set with spring 9.Being externally provided with sleeve 1 at brake bar, spring is positioned at sleeve, is provided with bearing 8 and sealing ring 4, is provided with oil filler point 7 on sleeve between brake bar and sleeve.
Being provided with handle 10 at telescopic upper end pull bar top, braking rope is fixed on telescopic upper end pull bar and handle junction by screw 2.In casing, the left and right sides is equipped with fixing bar, and both sides are equipped with braking rope in fixing bar.
The castor that bottom of luggage case is rolled with bottom by ratchet is meshed, thus reaches the effect of braking, utilizes spring card slot to realize upper and lower the moving freely of ratchet above ratchet, utilizes pulley to change pull bar and the roller not transmission effect in unified plane.
nullSuch as Fig. 1、Shown in Fig. 2，Two ends, luggage case all inner bodies left and right are symmetrical，So left and right two luggage wheel assembly of close trunk draw bar part only need to be allowed to realize braking function can realize the braking function of whole luggage case，Luggage case uses pull bar band pawl and engaging between ratchet，Steel wire rope is used to be connected between pull bar with ratchet，Spring spool is used to realize Telescopic between ratchet and axle，Ensure pull bar flexible come freely up and down the moving of band pawl，Thus realize the braking effect of pulley,Trunk draw bar is generally general scaler pull bar common on market，It is fixed on luggage case bottom，Braking rope termination is fixed together with pull bar handle position，I.e. when telescopic lever is fully extended，The drag hook driving reversible ratchet mechanism upper end moves up，Ratchet is made to leave ratchet surface，Release luggage wheel assembly on-position，When luggage case upper end pull bar is put down completely，When i.e. trunk draw bar is in contraction state，Guarantee that ratchet realizes luggage wheel assembly braking in embedding ratchet，Unnecessary brake cable is involved in and stores by the most collapsible Tape spring mechanism.
When needs pawl wheel, braking rope is kept to be in relaxation state, i.e. ratchet mechanism off position gets final product (note: spring has elastic force itself, when making camber of spring without external force, extended ratchet is made to embed between ratchet two tooth, owing to ratchet fixes with bonded with axle with luggage wheel assembly, therefore luggage wheel assembly can be realized and fix function) when needs release braking, being pulled upwardly by braking rope, ratchet leaves ratchet, and luggage case recovers to rotate.
Wheel bar upper end has pouring orifice, bottom to have sealing ring (seeing figure in detail), and a little lubricating oil is injected pouring orifice, keeps spine bar normal with rack inner wall two ends lubrication, moves up and down during bar lighter.
nullDuring pull bar is flexible, ensure that steel wire rope can shrink，Prevent from hindering moving freely of pull bar，So that it is guaranteed that freely the stretching of ratchet，When pull bar declines，Steel wire rope can bend，Spring wind tape mechanism is utilized to be stored by braking rope，Guarantee that it moves freely，The internal braking rope length of Tape spring need to be equal to the greatest length of luggage case telescopic bar institute tensible，Add Extensible pulling rod for trunk bottom part to the length of pulley，That is，When trunk draw bar is pulled to top，Braking rope wants the drag hook pull-up that can be connected by reversible ratchet mechanism with luggage case braking rope，Guarantee that ratchet leaves ratchet surface，Release luggage wheel assembly on-position，When luggage case upper end pull bar is put down completely，Guarantee that ratchet realizes luggage wheel assembly braking function in embedding ratchet，Unnecessary brake cable is involved in and stores by the most collapsible Tape spring mechanism.The luggage case lower left corner and the lower right corner are respectively arranged with a pulley and pulley frame, pulley is used for placing braking rope, braking rope is made to connect the drag hook of reversible ratchet mechanism, due to castor for trunk with pull bar the most in the same plane, utilize pulley to change the direction of doing exercises of steel wire rope, guarantee that ratchet is reliable with the connection of pull bar, preferably realize braking effect.
