Description

Middle rail for sliding rail slide-and-guide rod structure

Technical field

The utility model relates to sliding rail technical field, especially a kind of middle rail for sliding rail slide-and-guide rod structure.

Background technique

Sliding rail is also known as guide rail, slideway, refer to the drawer being fixed on the cabinet body of furniture, for furniture or cabinet plate enter and leave it is movable Hardware connecting component.The drawer that sliding rail is suitable for the wooden furniture such as with steel drawer such as cabinet, furniture, official document cabinet, bathroom cabinet connects It connects.

Currently, the structure of traditional sliding rail includes the middle rail being slidably connected on outer rail by middle rail ball retainer, in place In the internal rail being slidably connected on outermost middle rail by internal rail ball retainer, in the sliding rail course of work, during middle rail passes through Rail ball retainer with respect to outer rail carry out sliding motion, thus realize in rail relative to outer rail stretching with protrude into.

Guide post installation trouble in the prior art, functional reliability are poor.

Utility model content

The applicant provides a kind of structurally reasonable middle rail for sliding rail sliding for the disadvantage in above-mentioned existing production technology Guide post structure, to can limit it using slide-and-guide rod structure and move axially and have the function of anti-attrition.

Technical solution used by the utility model is as follows:

A kind of middle rail for sliding rail slide-and-guide rod structure, the structure of guide post are as follows: including connecting column, the two of the connecting column End has each extended over symmetrical front guide post and rear guide post, and above three pillar is in same axial location；The connection The middle part of column is equipped with positioning transfer part, and the end of the positioning transfer part is equipped with the anti-attrition piece greater than its end, the anti-attrition piece Horizontal plane it is parallel with three pillar axis.

As a further improvement of the above technical scheme:

Further include middle rail, slot respectively on the outside of the both ends of the middle rail, guide post is installed in the slot, the guide post The end that side chute and positioning transfer part and anti-attrition piece outside middle rail clasp slot is cut in outside front guide post and rear guide post, anti-attrition piece Outer end face is between the sliding rail face cooperated with the sliding slot.

The beneficial effects of the utility model are as follows:

The utility model is compact-sized, reasonable, easy to operate, by slotting in middle rail, is turned in the middle part of guide post by positioning Fitting is provided with anti-attrition piece, can effectively prevent the friction between on the inside of middle rail bottom portion and external slide rail, meanwhile, limit guiding The axial movement of column, functional reliability is good, and installation and removal are convenient.

Detailed description of the invention

Fig. 2 is the structural schematic diagram of the utility model.

Wherein: 1, middle rail；101, slot；2, guide post；3, front guide post；4, connecting column；5, positioning transfer part；6, anti-attrition Piece；7, rear guide post.

Specific embodiment

With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.

As depicted in figs. 1 and 2, the middle rail for sliding rail slide-and-guide rod structure of the present embodiment, the structure of guide post 2 are as follows: packet Connecting column 4 is included, the both ends of connecting column 4 have each extended over symmetrical front guide post 3 and rear guide post 7, and above three pillar is located In same axial location；The middle part of connecting column 4 is equipped with positioning transfer part 5, and the end of positioning transfer part 5 is equipped with greater than its end Anti-attrition piece 6, the horizontal plane of anti-attrition piece 6 are parallel with three pillar axis.

Further include middle rail 1, slot 101 on the outside of the both ends of middle rail 1 respectively, guide post 2 is installed in slot 101, before guide post 2 The outer side chute of middle rail 1 is cut in outside guide post 3 and rear guide post 7 and positioning transfer part 5 and anti-attrition piece 6 clasp the end of slot 101, is subtracted The outer end face of grinding 6 is between the sliding rail face cooperated with the sliding slot.

In actual use, guide post 2 is installed in the two sides external notches 101 of middle rail 1, slot 101 first, positioning turns Fitting 5 and anti-attrition piece 6 clasp the end of slot 101, and the outer end of anti-attrition piece 6 faces outwardly.It has better guiding function, limits simultaneously It is moved axially, reliable operation.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is within the protection scope of the utility model referring to claim, can make any type of modification.
