Description

The luggage case one hand is control duplex pull rod structure

Technical field

The utility model relates to a kind of luggage case duplex pull rod structure, refer to especially a kind of with singlehanded the luggage case one hand of controlling two-tube pull bar operation control duplex pull rod structure.

Background technology

The handle of general existing single tube pull rod device, for ease of gripping, generally all make T type structure, United States Patent (USP) the 6th, 434, No. 790 (Pull Rod of Luggage Travelling trunk pulling handle structural improvements) are one and represent product, and the single tube pull bar is in order to reach the identical mechanical strength of bearing with two-tube pull bar, all more than the twice greater than the two-tube caliber of two-tube at least pull bar, the consumptive material that makes the single tube pull rod device is much larger than two-tube pull bar for the caliber of general single tube pull bar.

Moreover, general singlehanded luggage case regardless of being T font pull bar or hollow pull bar, its transmission mechanism has only single downward active force, so the single tube pull bar only can be controlled in its lower end, can not be used in two-tube pull bar luggage case, also be that handgrip in the luggage packing list handgrip control duplex pull rod structure can't be broken through the technology of controlling of pull bar always, also thus cause the T type singlehanded this type of one hand of duplex pull rod live telecast that the luggage case market of duplex pull rod does not make further progress so far as yet, really remain necessity that the dealer researched and developed, breaks through.

Summary of the invention

Therefore, the purpose of this utility model is promptly in all shortcomings of improving above-mentioned existing trunk draw bar device, and provide a kind of luggage case one hand control duplex pull rod structure, it has singlehanded the luggage case telescopic lever device of two-tube pull bar, and can control the effect that two-tube pull bar opens and closes to single pushing by singlehanded.

A purpose more of the present utility model is to provide a kind of luggage case one hand control duplex pull rod structure, its structural design can be convenient luggage case singlehanded the one hand that is applicable to T type handgrip, hollow handgrip or other type etc., and have the selectivity characteristic of the polymorphic sample development of product.

Another purpose of the present utility model is to provide a kind of luggage case one hand control duplex pull rod structure, it has the one hand handle that three place's electing property comfortable grip are used, the joining place of this handgrip and two-tube pull bar has the mechanism of an alternative rotation, make handgrip when the walking of towing luggage case, the improper torsion that user's wrist is produced can give eliminating in right amount, to reach good gripping sense and labor-saving effect.

The technical solution of the utility model, include: a handle assembly, it includes a singlehanded handle, single handle pipe and transmission mechanism, and this one hand is the button that is provided with tool elasticity playback, and this button is this transmission mechanism that is in transmission connection, and this list handle pipe is the below that is connected this one hand handle; One housing is provided in a side of below single handle pipe of this handle assembly, has the space that is connected with this list handle pipe in it; The a pair of pull rod device is located at this housing below, and it includes duplex pull rod, a pair of being connected and be located at connecting elements and blocking device in this duplex pull rod; One controlling organization, be located in this housing, it includes the part that presses of this transmission mechanism of connection, this presses the following pressure side that the part both sides have this connecting elements of interlock, be that mat should one hand be pushed the single of last button, can press this controlling organization of part interlock via this, control the start that two-tube pull bar opens and closes and reach.

Aforementioned this transmission mechanism includes one and is located at the operating bar that this presses the part top by this button interlock; And this controlling organization includes one and is located at the bearing that presses part below, and one is located at the tension spring of bearing below, a pair ofly is hubbed on the housing and is subjected to this to press the seesaw unit that part is controlled, and this seesaw unit also links and controls this connecting elements; In addition, this presses part is can be formed in one with this operating bar.

Aforementioned this housing is equipped with ccontaining short cylinder post that should the list handle pipe, this cylindrical column upper end is the path barrel mast, path barrel mast lower end is a big footpath barrel mast, establish two ccontaining these on the diametrical position of footpath barrel mast greatly and press the groove of part, and should be provided with a recessed neck in list handle pipe lower end, recessed neck lower end has cross engagement groove and snapping portion, and makes this one hand the mechanism with selectivity rotation.

Aforementioned this housing and this list handle pipe also can be formed in one, and the spring of this button is replaced in this operating bar upper end sheathed, this press part be with this operating bar for spiral shell is solid mutually.

Using the beneficial effects of the utility model is to see through one hand the single pressing operation of last button, can control the start that the two-tube pull bar of luggage case opens and closes, and should one hand one hand handle applicable to classes such as general hollow or T types, also be applicable to one hand handle with selectivity rotation or fixed.
