Abstract

The present invention relates to a positioning device for a slide rail capable of restricting a mobile track under extension by a positioning piece connected to the mobile track and a retainer connected to a fixed track and dismissing the restriction by the operation of a relief piece, wherein the positioning piece connected to the mobile track has a flexible bar and a stopping pin; the flexible bar having a taper at its terminal and the stopping pin having a protruding column; the relief piece having a slot for hollow slot for accommodating the protruding column; the hollow slot having at least a cant corresponding to the protruding column; the retainer having a retaining piece corresponding to the flexible bar and a stopper corresponding to the stopping pin. When the mobile track is pulled outwardly, by the taper of the flexible bar propping to the retaining piece and the stopping pin propping to the stopper to restrict the mobile track bidirectionally and the operation of the relief piece, the stopping pin is capable of departing from the stopper and consequentially dissociating the mobile track.

V. Description of the Invention (1) [Technical Field] The present invention relates to a kind of slide rail positioning device, in particular, a movable rail body is stretched relative to a fixed rail body, and must be matched with a release member = ... there is an appropriate two-way Limits are lifted. The knowledge of cattle can limit the formation of it [Prior art] The learner 'is as shown in Figure 12 and used to describe the structure of the slide rail ^ τ ^ not commonly used, generally used Water in the drawer = activity, as disclosed in the legend, it is a three-segment type [also has two slaves δ and juice using its locally identical mechanism Yuandou second track is defined by location distinction, after the main-human + /, One weight / month.rr, including inner rail (A), middle coach (B) and outer rail (C), between the inner rail (A) and the middle rail, and between the middle rail and the outer rail. For the auxiliary sliding members (D) and (E) with balls, to facilitate sliding, and the = rail U) and the middle rail (B) are provided with a locking member (F) and a stop (G). ^ Provide that the inner rail (A) can be unidirectionally positioned when it is pulled out to the limit. In 1, 1 t is one end pivoted on the inner side of the inner rail (A) and can be pivoted and deflected / and the main body of the locking member faces inward. The pulling direction of the rail (A) is extended with a spring rod (fi), and a protrusion (F3) is provided on the side of the shift lever (F2), and the = force cup (^) is pressed against the inner rail (A ) Inner edge, so that the locking member (F) has the elastic force of partial return and protection. Hold the protruding position of the convex part (F3) and ^ cough = seat ⑹ is fixed at the front end of the middle rail 可供 for the inner rail ⑴ to insert the pedestal / the grooves conforming to the shape of the two sides of the body 加以) to support the building, and On the seat surface between the grooves (G1) on both sides, a protruding bar-shaped abutment block (G2) is formed; and the above-mentioned conventional articles are used in combination. As shown in FIG. 13, the sleeve is inserted into the middle rail. Tanaka rail (A) — when the operator stretches to the limit, it moves with the inner rail (a).

Page 8 1236523 V. Description of the invention (2) The stopper 可以 can prevent its inner rail (A) from being disengaged from the middle rail (β) by the convex part (F3) of the abutment block rail. Also, if you want to remove the inner) from the middle handle (B) (that is, the same timing as when the drawer is detached), the bureau y uses the locking member (F) lever (F2) to protrude from the middle rail (B) stop. The ^ 卩 lever section outside the seat (G) is used to press down the shift lever (F2), so that the locking member (F) is deflected and the ^ convex portion (F3) can be released from the stop of the stop (0) At the block (G2), the middle rail (B) can be pulled away without reaching the inner rail (A). The above-mentioned device of the locking member (F) and the stopper (G) can only prevent the inner rail U) from being directly separated from the middle rail (B) when the second track is pulled outside, and cannot be used by the The positioning of the locking member (F) and the stop (G) also provides the situation that the inner rail A is easily retracted into the middle rail (β). In this case, when the operator pulls out the "xuan inner rail (A) ) And it is inconvenient to use the items on its drawer (such as the keyboard) or to repair the parts combined with the slide rails. In addition, similar to the aforementioned consumer goods, U.S. Patent Nos. 4,547,973, 5,255,983, 5,542,759, 5,730,514, and 65,029, 10 also disclose conventional technologies in this field. Based on Shang Chen, the structural model of the conventional sliding control used for pull-out limiting positioning has the need for further improvement. The applicant is betting on in-depth research ’and finally has the invention. [Summary of the Invention] The purpose of the present invention is to provide a slide rail positioning device, which aims to prevent the slide rail from detaching from the slide rail in an extended state, and at least it can be limited that the movable rail body will not be easily inside. Shrinking, and can be coordinated with the operation of the release member to facilitate the release of the anti-detachment or anti-inner positioning effect.
