Abstract

The utility model relates to a length-adjustable draw bar, which comprises a base, a main bar, a branch bar, a handle and a switch. The main bar is disposed on the base, the branch bar is movably connected with the main bar, the handle is connected with the branch bar, the switch is disposed at the lower end of the branch bar, an abutting bar is disposed between the handle and the switch, and a mounting strip is arranged on the base and disposed inside the main bar and provided with concave holes which match with the switch in a gripped manner and are uniformly arrayed in the longitudinal direction. A user can position the switch in an optional concave hole according to needs, accordingly the purpose of optionally adjusting the length of the draw bar can be achieved, and the length-adjustable draw bar is convenient in use and simple in structure.

Description

A kind of length adjustment pull bar

Technical field

The utility model relates to a kind of length adjustment pull bar.

Background technology

The vigorous of general mood owing to travel in recent years makes suitcase and auxiliary product thereof also attract attention greatly jointly, even becomes the target that manufacturer the most actively researches and develops.And now on the market the most common to promptly be the suitcase of scalable pull bar length, utilize the son of suitcase upper connecting rod, female pipe box to close so that the length of pull bar can be adjusted, with reduce palpus the application of force and draw difference on the line height.Yet existing pull bar can only have two length to regulate when adjusting length, i.e. and minimum length the highest, and it is regulated length and fixes, and can not arbitrarily adjust its length according to user's needs, the use inconvenience.

Summary of the invention

But the technical problems to be solved in the utility model provides a kind of length regulated at will, and easy to use, length adjustment pull bar simple in structure.The utility model is achieved through the following technical solutions:

A kind of length adjustment pull bar of the present utility model comprises base, and is arranged on the female bar on the base, reaches the sub bar that flexibly connects with female bar, and the handle that links to each other with sub bar, and is arranged on the switch of sub bar lower end, is provided with between described handle and the switch and supports bar; Described base is provided with mounting bar, and described mounting bar is arranged in female bar, and described mounting bar is provided with in a longitudinal direction with switch and holds shrinkage pool cooperation, evenly distributed mutually.

As improvement, described switch comprises main part, and is arranged on the partes glabra in the main part, and is arranged on the spring of partes glabra side, and with support the bar butt, be used to promote the movable block of partes glabra; Described shrinkage pool holds mutually with partes glabra.

As improvement, described handle is provided with the button that promotes to support bar.

Length adjustment pull bar of the present utility model, because described base is provided with mounting bar, described mounting bar is arranged in female bar, described mounting bar is provided with in a longitudinal direction with switch and holds shrinkage pool cooperation, evenly distributed mutually, the user can be as required, switch is positioned at arbitrarily in the shrinkage pool, thereby reaches the length of adjusting yoke arbitrarily, it is easy to use, and is simple in structure.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.

Fig. 1 is the stereogram of the utility model length adjustment pull bar;

Fig. 2 is the cutaway view that female bar cooperates with sub bar in the utility model length adjustment pull bar.

The specific embodiment

See also Fig. 1 to shown in Figure 2, a kind of length adjustment pull bar of the present utility model, comprise base 1, and be arranged on female bar 2 on the base 1, reach the sub bar 3 that flexibly connects with female bar 2, reach the handle 4 that links to each other with sub bar 3, and be arranged on the switch 5 of sub bar 3 lower ends, be provided with between described handle 4 and the switch 5 and support bar 6; Described base 1 is provided with mounting bar 7, and described mounting bar 7 is arranged in female bar 2, and described mounting bar 7 is provided with in a longitudinal direction with switch 5 and holds shrinkage pool 70 cooperation, evenly distributed mutually.The user can be as required, switch 5 is positioned at arbitrarily in the shrinkage pool 70, thereby reaches the length of adjusting yoke arbitrarily, and it is easy to use, and is simple in structure.

Wherein, described switch 5 comprises main part 50, and is arranged on the partes glabra 51 in the main part 50, and is arranged on the spring 52 of partes glabra 51 sides, and with support bar 6 butts, be used to promote the movable block 53 of partes glabra 51; Described shrinkage pool 70 holds mutually with partes glabra 51.Described switch 5 is fixed on the sub bar 3 by a clamping element 8.Described handle 4 is provided with the button 40 that promotes to support bar 6, supports bar 6 and supports movable block 53, thereby realize holding of partes glabra 51 and shrinkage pool 70.

The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field; all equivalences of being done according to the described process for making of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
