The positioning block 53 is convexly provided with a positioning protrusion 531 and correspondingly embedded. The second guiding groove 24 is disposed in the second guiding groove 24, and the linking block 54 is folded over the positioning block 53 in the receiving groove 53 and is opposite to the first guiding groove 24. The side of the linking block 54 is provided with a convex rib 541. Abutting against the upper edge of the first guiding groove 24, so that the linking block 54 can be slid along the upper edge of the first guiding groove 24 by the convex rib 541, and the embedded block of the front end of the passive sliding block 50 is pivoted. The 56 is abutted against the lower wall of the second guide groove 24, and an elastic member 291 is connected between the nesting post 25 and the sleeve 29 of the engaging portion 22, and the elastic member 291 is oppositely received by the engaging portion 22. In the long groove 221, by the above structure, a push type slide rail structure is completed.

The state in which the structure is actually used, as shown in FIG. 4, when the rail body 10 is not actuated and the inner rail 12 and the outer rail 11 are in a retracted positioning state, the passive slider 50 is in the positioning device 20. The inner portion of the engaging portion 22 is such that the linking block 54 of the passive slider 50 abuts against the upper wall of the receiving groove 52, and the rib portion 541 abuts against the upper edge of the first guiding groove 23, and the positioning block The 53 series is stacked under the linking block 54 , and the positioning post 531 of one side is fitted into the positioning notch 311 of the positioning convex portion 31 along the second guiding groove 24 , and is moved upward and upward to disengage from the second guiding slot. 24 is limited to the inside of the through slot 27, and the guiding inclined wall 42 of the linking guide block 40 correspondingly falls into the yaw space 282, and the limiting recess 43 is pushed upwards immediately below the positioning guiding block 30, thereby The passive slider 50 is in a positioning state on the engaging portion 22 of the positioning device 20, and the inlay block 56 at the front end of the passive slider 50 is positioned in the opposite direction from the limiting stud 121 of the inner rail 12. The inner rail 12 is restrained from being positioned in the outer rail 11 to form a retracted state, and the elastic member 291 is formed into a stretched state. When the inner rail 12 is to be slid out from the outer rail 11 by the above state, please also refer to As shown in FIGS. 5-8, the inner rail 12 is first pressed inwardly, and the inner rail 12 is forwardly abutted against the passive slider 50, so that the passive slider 50 is first displaced inward on the engaging portion 22, and the passive portion is at this time. The positioning block 53 inside the slider 50 is displaced downward due to the gap in the cavity 52, so that the positioning protrusion 531 is displaced downward along the wall edge of the through slot 27 and abuts against the linkage The limiting groove 43 of the guiding block 40 further causes the guiding inclined wall 42 of the linking guide block 40 to float upward, so that the positioning protrusion 531 slides along the interlocking guiding block 40 to the second guiding slot 24 to be disengaged. The state of the interlocking block 54 is displaced backward by the passive slider 50 and is placed against the positioning protrusion 31 of the positioning guide block 30 against the protruding post 542, thereby reusing the passive slider 50 after being disengaged from the positioning state. The springback of the elastic member 291 is reset, so that the passive slider 50 is further displaced outwardly on the engaging portion 22, and the positioning guide block 30 is further slid down the through slot 27 into the second guiding slot 24, and abuts against the linking guide block. The limiting groove 43 of the 40, so that the front end guiding inclined wall 42 is lifted up and away from the linking guide groove, so that the guiding guide block 40 and the second guiding groove 24 are guided, and the internal groove of the receiving groove 52 is connected.

On the side of the portion 31, when the passive slider 50 is further displaced inwardly to the end of the stroke of the engaging portion 22, the positioning block 53 is brought inwardly and the positioning protrusion 531 passes through the second guiding slot 24 to pass through the slot. The displacement section of 27 is further abutted against the abutment post 542 of the linkage block 54 The positioning protrusion 31 is positioned to be pushed and slid along the through slot 27 against the second guiding slot 24, and the positioning slot 311 of the positioning protrusion 31 is opposite to the front of the positioning protrusion 531, and finally placed When the inner rail 12 is opened, the passive slider 50 is rebounded by the elastic member 291 and then displaced outward. At this time, the positioning block 53 is inserted into the positioning notch 311 by the positioning protrusion 531, and is displaced forwardly. The positioning block 30 is positioned to move the positioning protrusion 31 of the positioning guide block 30 upward along the through slot 27, and the positioning block 53 is restricted by the positioning protrusion 531 in the positioning slot 311, so that the positioning block 53 is synchronized with the positioning convexity. The portion 31 is displaced upward in the cavity 52, and the rib 541 is attached to the upper edge of the first guiding groove 23 against the linking block 54, thereby positioning the positioning post 531 and the positioning convex portion of the positioning block 53. The positioning notch 311 of the 31 is restricted to form a positioning state in the through groove 27, whereby the inner rail 12 can be retracted and the positioning of the outer rail 11 is formed.

With the structure of the above specific embodiment, the following benefits can be obtained: the slide rail body 10 of the present invention is provided with a positioning device 20 and a passive slider 50, and the positioning device 20 is internally provided with a positioning of the passive slider 50. The guiding block 30 and the interlocking guiding block 40 enable the sliding rail to have a state of being fixed and fixed by pressing. When the drawer is connected with the inner rail 12 to push and fold, the crucible can drive the passive slider 50 to the positioning device 20. The engaging portion 22 is slidably moved, and the positioning block 53 and the linking block 54 are displaced relative to the second guiding groove 23 and the first guiding groove 24 on the engaging portion 22, and the positioning block 53 and the positioning guide block 30 are reused. The interlocking relationship between the interlocking guide blocks 40 forms a positioning state, and the positioning block 53 and the positioning guide block 30 limit the positioning, and the limiting studs 121 of the inner rail 12 are also simultaneously constrained by the fitting block 56, thereby The passive slider 50 and the positioning device 20 form a positioning state, and the positioning of the inner rail 12 and the intrusion block 56 of the passive slider 50 is restricted, so that the drawer member can be positioned when being folded, and the drawer member is prevented from being folded. Sliding out again to form a missing user When reopening and wish, and then the drawer rail 12 is pressed inwardly from the restrictor member can serve joint The position state, that is, the drawer can be pulled out for use, to increase the utility of the drawer slide.
