Description

Structure improved Travelling trunk pulling handle

The utility model relates to a kind of Travelling trunk pulling handle structure, but refers to the pull bar of the suitcase of a kind of stepless location especially.

The Tiebar structure of at present commercially available a kind of suitcase is numerous, though can provide convenience for the traveller travels outdoors, in use still has some unsurmountable defectives.As the inventor at first to file utility model patent " Travelling trunk pulling handle ", patent No. ZL94238575.6, the pull bar of this suitcase are two-part, though can adjust the height of pull bar, can't adopt stepless to locate the requirement of satisfying the user; The sleeve of this Travelling trunk pulling handle is hollow tube, and be provided with some locating holes in this sleeve, therefore when the suitcase load-carrying tows, often low the causing of intensity because of sleeve pipe can't load-carrying tow flexural deformation, and then makes the interior hollow lever of sleeve stuck and can't adjust the height of pull bar again.

In sum, the inventor is to be engaged in Travelling trunk pulling handle manufacturing industry many years of experience based on aforesaid disappearance, and tows test through load-carrying, proposes the utility model eventually.

But the purpose of this utility model is to provide a kind of stepless the location and Travelling trunk pulling handle one-hand operation; And increase the intensity of this pull bar, make it to be adapted to heavy duty and tow.

The purpose of this utility model is achieved in that a kind of structure improved Travelling trunk pulling handle, comprises that leader's body, controlling organization, lower cover, transmission mechanism, interlinked mechanism, hollow lever and sleeve form; Wherein the two ends of handle body are provided with open-work, then establish a pull bar slot in open-work is other, then are provided with a clamping block groove in the lower end of pull bar slot; Pull bar in the controlling organization is located at a side of handle body, and this pull bar closes with the clamping block bolt that is inserted in the pull bar slot, the both sides of clamping block respectively are provided with an arc hole and a keyhole, and a long bolt is inserted in this arc hole, and an end of this long bolt protrudes from the clamping block groove outside; The upper end of the depression bar in this protruding end compressing transmission mechanism, the below of this depression bar is then sheathed goes into spring and locating piece; The lower end of depression bar is connected in the gore of interlinked mechanism, and the hypotenuse of the hypotenuse of this gore and a valve seat joins, and is installed in the stationary magazine creel, and the projection of valve seat is subjected to the contact of a spring and protrudes from outside the breach of stationary magazine creel; Above-mentioned depression bar is located in the hollow lever, and this hollow lever is set in the sleeve; It is characterized in that described sleeve is hollow form, its cross sectional shape is combined by round and a rectangle intersection, sleeve is circular in the cross section to have extended chimeric wall with the rectangle intersection position along inner edge, be fitted with the locating hole seat in the rectangular end outside chimeric wall, then be provided with locating hole on this locating hole seat, the projection sleeve of above-mentioned valve seat is gone in it.

The utility model in use, as long as stir pull bar with finger, it is down movable along the circular arc in the arc hole of clamping block to make pull bar drive long bolt, so that the depression bar of the past lower compression transmission mechanism of long bolt down, the gore that down drives its lower end simultaneously at depression bar down, send length each other with the long hypotenuse that impels gore and valve seat, valve seat is subjected to the relation of gore that the valve seat projection is contracted to stationary magazine creel by the breach of stationary magazine creel, so that whole pull bar is the movable telescopic state; Be back to the origin-location at pull bar by springback, so that depression bar is not when being subjected to the compressing of long bolt, depression bar is subjected to springback to go back to the origin-location and also drives gore up, and valve seat is subjected to the extruding of spring and make projection protrude in the breach of stationary magazine creel, and insert in the locating hole of the locating hole seat in the sleeve of desired height, thereby finish the location height of steady brace stepless; Because the locating hole seat that inserts in the rectangular end of sleeve is an entity shape, therefore strengthen the intensity of sleeve greatly in addition, made the utility model can be suitable for load-carrying and tow, thereby realized the purpose of this utility model.
