Description

Slide rail structure

The present invention relates to a slide rail structure, and more particularly to a slide rail structure having a large reset stroke. Background technique

At present, common drawers, keyboards, etc., in order to facilitate the pull-out and reset, will combine the slide rail device with inner, middle and outer slide rails, and the slide rail device is fixed on the book frame or the bottom of the table by using the outer slide rails. The inner slide rail is combined with the outer side of the drawer and the keyboard to facilitate the drawer, the keyboard pumping, etc., based on the outer slide rail fixed with the book frame and the desktop, and is accommodated through the middle, inner and outer slide rails. Steel ball, to achieve the drawer, keyboard pumping effort to pull out, push into the reset effect.

In order to make the middle and inner slide rails have the effect of positioning and automatic resetting when the inner and inner slide rails are accommodated inside the outer slide rail, a reset unit is provided at the bottom of the outer slide rail, and the reset unit is used to exert the above effects; however, The reset unit needs to occupy a certain length of space at the bottom of the outer slide rail. Therefore, in order to match the space of the reset unit, the length of the middle and inner slide rails needs to be shorter than the length of the outer slide rail, otherwise it may not be completely included in the outer slide rail, and The length of the middle and inner slide rails needs to be shorter than that of the outer slide rails. Therefore, when the outer, middle and inner slide rails are all deployed, the overall length of the slide rails must be smaller than the ideal full length, and the so-called ideal full length is If the actual length of the full slide is closer to the ideal full length, the full extension ratio is better, and the smaller length can be used to achieve a larger extension effect, and the middle rail and the inner rail are not required to be used. The length of the rail breaks the strength of the middle rail, because the sliding rail of the buffer mechanism generally cuts the middle rail into a concave shape at the end of the contact buffer mechanism, so as to accommodate the buffer mechanism to lengthen the length of the middle rail Such a slide rail exhibits a longer and stronger strength, and can exhibit an extension effect, so that the slide rail can exert the maximum extension effect, and the utility model also has high utilization for the slide rail.

Referring to FIG. 1 , a slide rail device 9 mainly includes: an outer slide rail 90 , a middle slide rail 91 , an inner slide rail 92 , a slide rail 93 , and a buffer 94 . The outer slide rail 90 has a U-shaped cross section, and the outer slide rail 90 defines a sliding space 903 by sealing the two open end stop blocks 901 and the fixed seat 902. The middle slide rail 91 is limited by the slide rail 93, so it is necessary to open a gap 910 on the middle slide rail 91. The inner slide rail 92 is received in the sliding space 903 and is free to slide relative to the outer slide rail 90, and a hooking member 920 is disposed at one end of the inner slide rail 92 corresponding to the fixed seat 902. The sliding rail 93 is a closed rail that is fixed on the fixing base 902 and received between the inner sliding rail 92 and the fixed seat 902. When the sliding rail 91 slides, the sliding rail 93 is received in the notch 910. Inside. The sliding rail 93 is engaged with the hooking member 920 on the inner sliding rail 92 by a positioning fastener 930 to be in a predetermined distance (ie, the positioning movement of the positioning fastener 930 is closed). The limit of the slide rail 93). The bumper 94 is disposed on the mount 902.

Since the gap 910 is formed in the middle slide rail 91 of the above-mentioned prior art structure, the length of the middle slide rail 91 and the structural loss are caused, which is inconvenient to use. Moreover, the inner slide rail 92 also has no other matching design, so that the inner slide rail 92 cannot effectively extend or contract. Therefore, this prior art rail device still has the drawback of poor extension length.

On the other hand, the prior art slide reset device 9 has an automatic resetting and cushioning effect, but since the damper 94 is disposed at the bottom end of the outer slide rail 90, and the damper 94 is generally a gas. The chamber is used to push the air chamber to obtain a reaction force, thereby providing a cushioning effect. Because the buffer 94 itself and the push rod have a considerable length, they occupy a part of the length of the outer slide rail 90, and when the inner slide rail 92 is automatically reset, it needs to be indirectly pushed against the buffer 94 to have a buffering effect, so the inner slide The length of the rail 92 is rather limited, so the full length of the body is also considerably limited, so that the existing design is not practical. '

Furthermore, the overall design of the slide rail, in addition to the above-mentioned full length, the size adaptability of the reset unit and the outer slide rail is another point. Generally, the reset unit is the inner wall of the outer slide rail, so the reset unit must be external The inner diameter of the slide rail is matched, otherwise it will not be able to displace along the outer slide rail. However, in the case of corresponding outer slide rails of different sizes, it is necessary to design different size reset units to adapt to the outer slide rails. For storage and production, There is a inconvenience. In view of the above two major points concerning the overall length and size adaptability of the slide rails, the applicants of the present invention are often unable to be considered. Therefore, the research and development has improved the present case, and it is hoped that the structure of the present invention can be used to improve the lack of the prior art. Summary of the invention

For the above purpose or other purposes, the present invention adopts the following technical solution: a slide rail structure, The utility model comprises an outer slide rail, a middle slide rail, an inner slide rail and a reset unit. Wherein, the outer slide rail has an outer rail space, the outer rail space is used to accommodate the middle slide rail, the inner slide rail and the reset unit; the middle slide rail can slide in the outer rail space, and the middle slide rail has a middle rail space The inner slide rail can be accommodated; the inner slide rail is accommodated in the middle slide rail and can slide in the middle rail space. The reset unit is assembled at one end of the outer rail space, and the reset unit includes a fixing member disposed in the outer rail space such that one end of the outer rail space has a closed end; a sliding rail disposed at one end of the fixing member, and the sliding rail is disposed on the middle rail a doffering space at the bottom; a movable member disposed in the outer rail space and slidable along the sliding track, the sliding member can slide the movable member in the outer rail space; a snap member disposed on the movable member; at least one An elastic member disposed between the fixing member and the movable member; a guiding member disposed on the inner sliding rail; and a sliding space at the bottom of the middle sliding rail, when the inner sliding rail slides in the outer rail space, the sliding rail It can be extended into the dodge space to increase the sliding range of the middle slide rail and increase the length of the middle slide rail; a dodging groove provided on the fixing member and the movable member can be crossed when the inner slide rail slides in the outer rail space The dodge slot reaches the closed end of the outer slide rail, so that the length of the inner slide rail is as long as the outer slide rail segment.

Compared with the prior art, the reset unit of the novel slide rail structure is provided with a slide rail on the fixing member, so that the movable member can be matched with the inner wall width dimension of the outer slide rail, and a reset unit of a specification can be matched with various sizes. The use of the outer rails can help to simplify the warehousing and manufacturing problems and reduce inventory and reduce manufacturing costs. Because the sliding track corresponds to the dodging space of the middle sliding rail, the middle sliding rail is not obstructed by the sliding rail, and can effectively extend into the outer rail space to be close to the end, and then cooperate with the design of the dodging groove on the reset unit to make the inner sliding The rail can also be shrunk to the end of the outer rail space. Because the outer slide rail has better accommodation, the length of the middle slide rail and the inner slide rail can be increased, so that the novel has a better overall length and increases during the whole exhibition. The proportion of the entire exhibition. The utility model further comprises a buffering member, wherein the buffering member can be disposed at the same end or different end of the outer sliding rail as the resetting unit, and the buffering function provided by the buffering member can alleviate the contraction speed of the elastic member, and the buffering member is arranged in the middle sliding The bottom of the rail is in the doffer space, so the reset unit can appropriately reduce its length, and the range in which the middle rail can be slipped is increased, so that a longer middle rail can be used, so that the body has a better full length. Therefore, this practical type is a new type that is quite practical and creative, and it is worthy of promotion by the industry and publicized to the public. DRAWINGS
