Abstract
The utility model discloses a kind of case drawbar structures, including the first trombone slide, first, second guide sleeve and the second trombone slide are installed in first trombone slide, second trombone slide is located in first, second guide sleeve, and the ball being pressed into contact on the outside of several and second trombone slide is provided in first, second guide sleeve.In this case drawbar structure, positioning is contacted with the second trombone slide by the ball in the first, second guide sleeve, the transverse shakiness of case drawbar is greatly reduced, keeps the overall structure of case drawbar more stable, and keep case drawbar flexible more smooth instead of conventional slip structure with rolling structure.
Description
Technical field
The utility model relates to a kind of guide rail structure, especially a kind of case drawbar structure.
Background technique
In luggage structure, case drawbar is important building block, and length is scalable with convenient to use.In existing skill
In art, case drawbar is formed by several sleeve combinations, realizes that pull rod is flexible by the mutual fitting of casing.However, this
In Tiebar structure, the gap between casing is larger, is easy to appear transverse shakiness, structural instability, and enhanced stretch resistance is big, uses
It is not smooth enough.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of case drawbar structure, stable structure, use is smooth.
In order to solve the above-mentioned technical problem, a kind of case drawbar structure of the utility model, including the first trombone slide, described
First, second guide sleeve and the second trombone slide are installed, second trombone slide is located at first, second guide sleeve in one trombone slide
It is interior, the ball being pressed into contact on the outside of several and second trombone slide is provided in first, second guide sleeve.
Third, the 4th guide sleeve and third trombone slide are installed, the third trombone slide is located at described in second trombone slide
In third, the 4th guide sleeve, it is provided with several outer side compressions with second trombone slide in the third, the 4th guide sleeve and connects
The ball of touching makes case drawbar have three section stretching structures, has bigger tensile elongation, using more convenient.
It is separately provided for enabling pull rod with the rolling groove of the ball engagement on the outside of second trombone slide, third trombone slide
Structure is more stable, stretches more smooth.
Be respectively arranged with the first locating slot in first, second guide sleeve, have on the outside of second trombone slide with this
First positioning chimb of a positioning groove corresponding matching；It is respectively arranged with the second locating slot in the third, the 4th guide sleeve, it is described
Have on the outside of third trombone slide and positions chimb with the second of the second locating slot corresponding matching.Enable product structure cooperation accurate.
The beneficial effects of the utility model are: passing through the ball in the first, second guide sleeve in this case drawbar structure
Positioning is contacted with the second trombone slide, greatly reduces the transverse shakiness of case drawbar, keeps the overall structure of case drawbar more stable,
And keep case drawbar flexible more smooth instead of conventional slip structure with rolling structure.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to Fig.1, a kind of case drawbar structure of the utility model, including the first trombone slide 1 are equipped in first trombone slide 1
First, second guide sleeve 2,3 and the second trombone slide 4, the second trombone slide 4 are located in the first, second guide sleeve 2,3, and first, second leads
Several balls 5 being pressed into contact with the second trombone slide 4 outside are provided with into set 2,3.
In the present embodiment, third, the 4th guide sleeve 6,7 and third trombone slide 8 are installed, third is drawn in second trombone slide 4
Pipe 8 is located at third, in the 4th guide sleeve 6,7, is provided in third, the 4th guide sleeve 6,7 several with the second trombone slide 8 outside
The ball 5 being pressed into contact with.Second trombone slide, 4,8 outside of third trombone slide are separately provided for the rolling groove 9 with ball engagement.The
One, the first locating slot 10 is respectively arranged in the second guide sleeve 2,3, it is right with first locating slot 10 to have on the outside of the second trombone slide 4
The the first positioning chimb 11 that should cooperate.The second locating slot 12 is respectively arranged in third, the 4th guide sleeve 6,7, outside third trombone slide 8
Side, which has, positions chimb 13 with the second of 12 corresponding matching of the second locating slot.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
