Abstract
The utility model discloses a bag and suitcase pull rod device. The pull rod device comprises a plurality of pipes, springs and spring seats, which are sleeved mutually. The pull rod device further comprises a bounce chock plug. The bounce chock plug is arranged between the two spring seats to support the springs. The utility model has the advantage that the bounce chock plug is added to a bounce device in the bag and suitcase pull rod device, which can avoid the instability phenomenon caused by the thin and long springs, therefore the pull rod can be used smoothly and the stuck phenomenon can not appear.
Description
Technical field
The utility model relates to the pull rod device of a kind of trolley luggage, particularly a kind of trolley luggage.
Background technology
Draw-bar box is provided with pull rod device on chest, in tow, reduce the heavy burdens greatly during with convenient walking.Described pull rod device mainly by together pipe fitting of mutual sheathing, each pipe fitting is stretched or the locking device and the bouncer of return constitute.Bouncer mainly is made of spring and the spring base that is positioned at both ends of the spring in the existing pull rod device.Because Tiebar structure characteristics, spring often belongs to thin and tall type, and only relies on the spring base location that is positioned at both ends of the spring, and thin and tall spring stability is not enough, easy buckling deformation, this just causes this pull rod device, and pull bar badly draws in use, situation stuck, that have some setbacks when using takes place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of smooth and easy, difficult stuck case drawbar device that takes place that uses is provided.
A kind of case drawbar device comprises mutual sheathing complex root pipe fitting together, spring, and spring base, its structural feature is: described pull rod device also includes the spring chock plug, and described spring chock plug is arranged between two spring bases and props up spring.
Between spring base, be provided for the spring chock plug of support spring, so just can avoid because of the meticulous long phenomenon that causes taking place in use unstability of spring, thereby make spring can remain better elastic power, and make pull rod device have all the time the pulling smooth and easy, be difficult for stuck advantage.
Spring chock plug between described two spring bases is arranged at the stage casing of spring.
In the stage casing of spring the spring chock plug is set, has the good supporting effect.
Spring chock plug between described two spring bases is stuck in spring and is arranged on the spring.
Spring chock plug between described two spring bases or be arranged on the pipe fitting.
Described spring chock plug or be I-shaped, or be flute profile.
In sum, advantage of the present utility model is:
Added the spring chock plug in the bouncer of the utility model in the case drawbar device, can avoid like this, thereby it is smooth and easy that pull bar is used, and phenomenons such as stuck can not take place because of the meticulous long unstable phenomenon that takes place of spring.
