Abstract

The utility model relates to a pull rod assembly for a suitcase, which is composed of a pull rod and a rod holder which can be fixed on the suitcase, wherein a bearing concave which can be inserted by the pull rod is arranged on the rod holder, a fastening mechanism is arranged between the end part of the pull rod and the bearing concave of the rod holder, and the pull rod and the rod holder are conveniently disassembled or installed and positioned by utilizing the fastening mechanism. The utility model has the advantages of simple structure, reasonable design, convenient operation and control, and no space occupation in the suitcase; furthermore, the utility model is particularly suitable for being designed into a suitcase with single pull rod, and the utility model has the characteristics of compactness and portability.

Description

The case drawbar assembly

Technical field:

The utility model belongs to the small stores field, relates in particular to the dismountable case drawbar assembly of a kind of pull bar.

Background technology:

Existing most case and bag all are equipped with pull bar and horn ring, realize that the slip of case and bag tows, and alleviate the journey hard work.The pull bar major part is a multi-section structure, in the majority with two joints and three joints, respectively with two or three sheathed forming of rod member, be in inboard Rod end and be fixed with elastic plug, the horizontal bolt of the elasticity of stopper ejects and can pin on the rod member preformed hole of the outside, in the time of can being implemented in the retraction at least and location when being pulled to maximum.The tradition pull bar is all hidden and is located in the case and bag, takies space in the valuable case, and how solving this contradiction promptly becomes problem of the present utility model.

Summary of the invention:

The purpose of this utility model is a kind of pull bar of design detachably separates collection with case and bag a case drawbar assembly.

Technical solutions of the utility model are achieved in that a kind of case drawbar assembly, are made up of pull bar and the pole socket that can be fixed on the case and bag, wherein offer one on the pole socket and can make holding of pull bar insertion recessed, and tie rod end and pole socket hold recessed and be provided with engaging support mechanism.Utilize engaging support mechanism to make and be convenient to dismounting between pull bar and pole socket or the location is installed.

It is scalable in holding the pin-and-hole that cooperates with it that resilient key in recessed and tie rod end are provided with that described engaging support mechanism refers to that pole socket is provided with, and controlling by system of resilient key is convexly set in the pole socket surface.Control by system and can remove the locked state of resilient key, be convenient to control the dismounting of pull bar pull bar.

The utility model is simple in structure, reasonable in design, control conveniently, do not account for space in the case, is particularly useful for being designed to the case and bag of single pull bar, has small and exquisite, light characteristics.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further:

Fig. 1 rod assembly one schematic perspective view

Another angle schematic perspective view of Fig. 2 Fig. 1

Fig. 3 rod assembly two schematic perspective views

Wherein

1-pull bar 11-pin-and-hole 12-skewed slot

2-pole socket 21-screw hole 22-holds recessed

23-resilient key 24-is by system 25-protruding pin

The specific embodiment:

See figures.1.and.2, the case drawbar assembly, main body is by steel pipe or pull bar 1 pipe fitting of aluminium alloy stretching and the pole socket 2 of plastic cement injection mo(u)lding, be reserved with on the pole socket 2 in order to be positioned at the screw hole 21 on the case and bag, also offer on the pole socket 2 one can make that pull bar 1 inserts hold recessedly 22, pull bar 1 end and pole socket hold recessed 22 and are provided with engaging support mechanism.

Engaging support mechanism refers to pole socket 2 resilient key 23 is installed in the legend, resilient key 23 is scalable in holding in recessed 22, the pin-and-hole 11 that cooperates with it that pull bar 1 end is provided with, controlling by system 24 of resilient key 23 is convexly set in pole socket 2 surfaces, remove when sealed, only with hand or pin dub by system 24 can make resilient key 23 retractions.This resilient key is a prior art, and is identical with the plug structure that is installed on tie rod end.

With reference to Fig. 3, engaging support mechanism can also be divided into pole socket hold recessed 22 and pull bar 1 end on protruding pin 25 and skewed slot 12.Pull bar 1 end is inserted and to be held in recessed 22, and with 12 mouthfuls of alignment of skewed slot protruding pin 25, and rotating rod 1 makes protruding pin 25 slip into skewed slot 12 depths can to realize both sealed location; Inverse operation can be removed.Protruding pin also can be in pull bar one side, and corresponding skewed slot can be opened in pole socket one side.

Remove above-mentioned two kinds of engaging support mechanisms, also can adopt threaded engagement mechanism, hold in recessed 22 and be provided with internal thread, the external screw thread that cooperates is with it established in pull bar 1 end.

Pull bar 1 can adopt multi-section structures such as binodal or three joints, at least respectively be provided with a pin-and-hole 11 in proximal end, two ends up and down on the wherein outer lateral bracing strut, wherein Di Bu pin-and-hole 11 cooperates the more piece pull bar effect that can pin folding retraction with the stopper of inboard tie rod end, and the more piece pull bar after avoiding dismantling skids off; And the pin-and-hole 11 on outer lateral bracing strut top provides when using, and interior lateral bracing strut is pulled out location and stressed effect.
