Please refer to Fig. 1 to Fig. 6, the slide rail top pressure opening structure of the present invention is mainly to provide the reciprocating pull of the carrier, which includes the outer slide rail 10, the inner slide rail 20 and the pull rod 30, wherein the inner slide rail 20 is installed in the outer slide rail 10, and the pull rod 30 is combined in the inner slide rail 20. By pulling the pull rod 30, the inner slide rail 20 is driven to slide, so that the carrier moves back and forth.

The utility model is provided with a top buckle 1 and a buckle 2 at the inner side of the outer slide rail 10 and the pull rod 30, and utilizes the catch action between the top buckle 1 and the buckle 2 to control the pressing and opening of the carrier.

A top fastener 1 is at the inner end of the top fastener 1, which includes a body 11, a bearing plate 12, an elastic component 13, a positioning fastener 14 and a sliding sleeve 15 and other components, wherein the body 11 and the bearing plate 12 are integrally connected The carrying plate 12 is extended from the central side of the main body 11, and the two sides of the main body 11 are respectively protrudingly provided with shaft columns 113. The connection between the main body 11 and the carrying plate 12 is provided with a movable groove 114, and the movable groove 114 is connected to the The container 111 on the back of the body 11 is provided with an elastic component 112 inside the container 111 .

A shaft hole 121 , a chute 122 and a foolproof groove 123 are arranged on the surface of the bearing plate 12 , two slide rails 125 are arranged on the back of the bearing plate 12 , and a positioning piece 124 is arranged at the end of the slide rail 125 .

The bottom surface of a positioning fastener 14 is provided with a shaft 141 and a protrusion 142, a hook 144 is provided at the inner end, and a guide post 143 is provided at the end of the surface. , the protruding block 142 is just combined inside the sliding groove 122, and the hook 144 protruding from the inner end is embedded in the movable groove 114 of the body 11, and combined with the elastic component 112 arranged in the containing groove 111; when the fastener 14 is positioned with When the shaft 141 pivots in the shaft hole 121, the protrusion 142 limits the pivoting angle in the sliding groove 122, and the hook 144 drives the elastic component 112 to move, and the elastic component 112 provides the positioning fastener 14 to return Normal settings.

A pair of elastic components 13 are sheathed on a pair of shaft posts 113 of the body 11 .

A sleeve 151 is provided at both ends of a sliding sleeve 15, the sleeve 151 can be combined with the elastic component 13, the body of the sliding sleeve 15 is combined under the bearing plate 12, and can slide on the slide rail 125 of the bearing plate 12 , and the sliding sleeve 15 can be limited by the positioning piece 124 to slide the stroke.

The body 11 of the top fastener 1 and the bottom surface of the sliding sleeve 15 are both fixedly combined with the slide rail 10 .

Referring to FIG. 1 and FIG. 6 again, there is a protruding piece 301 and a shaft 302 on the inner surface of the pull rod 30 , which can be combined and fixed by the fastener 2 . Wherein, the fastener 2 is combined with the introduction part 22 and the shaft seat 23 by the connection part 24, the introduction part 22 and the shaft seat 23 are protrudingly arranged above the connection part 24, and the connection part 24 is embedded in the pull rod 30 and fixed , the introduction part 22 of the fastener 2 has an arrow-like shape formed by the guide edge 221, the inclined surface 223 and the concave groove 222; 222 are separated by a certain distance and form a channel; the positioning hook 21 at the end of the fastener 2 is hooked on the tab 301 of the pull rod 30 , and the shaft body 302 is inserted into the shaft hole 231 .

Please also refer to FIG. 1 and FIG. 7 to FIG. 9. When the slide rail is in the locked state, the inner slide rail 20 is pressed against the sleeves 151 on both sides of the sliding sleeve 15 of the top fastener 1 after being pushed inward. And when the pull rod 30 is pushed to the inside and leans against the inner slide rail 20, the pull rod 30 will drive the inner slide rail 20 to slide, and at the same time push the sliding sleeve 15 to make the elastic component 13 produce a compressed state. When the pull rod 30 moves inward When moving to a certain degree, the fastener 2 on the pull rod 30 is in contact with the guide post 143 with its introduction part 22, and guides it along the guide edge 221 of the introduction part 22, so that the guide post 143 enters smoothly into the recessed groove 222. Positioning, when the guide post 143 is combined and positioned in the recessed groove 222 , the top fastener 1 and the fastener 2 are engaged with each other to achieve a locked state.

And, when wanting to reach the opening state to the slide rail, referring to Fig. 10 to Fig. 11, the pull bar 30 needs to be pushed out again. The other end of the opening of the concave groove 222 moves out, and returns to its original position along the slope 223 . At this time, after the pull rod 30 is disengaged from the engagement with the top fastener 1, the inner slide rail 20 is subjected to the elastic force of the pair of elastic components 13, and the inner slide rail 20 is further pushed outward by means of the sliding sleeve 15, so that the drawer carrier can be used The slide rail pushes away a gap to facilitate opening.

Between the opening and locking of the slide rail, the pivoting action of the bearing plate 12 and the fastener 2 is used to achieve the top pressure opening and locking of the slide rail, and this top pressure opening structure can be provided as a desk drawer, computer desk, etc. Drawers, industrial servers or computer cabinets, and this type of top pressure structure can achieve the effect of opening and locking by applying force to the slide rails on both sides, which can provide the cabinet with a beautiful appearance with hidden handle design, and the top The pressure type is easy to operate and the cabinet is easy to open.

In addition, please refer to Fig. 1 and Fig. 12 again. When the operator opens the cabinet body by pulling it out by mistake, it will inevitably cause damage to the slide rails. Regarding this problem, this problem is also considered in this utility model. In particular, a fool-proof groove 123 is provided on the loading plate 12 (that is, below the position where the guide post 143 of the positioning fastener 14 is set); The force touches the bearing plate 12, and the protruding guide post 143 on the bearing plate 12 bears the brunt of the most easily damaged. At this time, the anti-fooling groove 123 will play a role, and the guide post 143 can be elastically retracted, thereby avoiding improper opening. damage.

To sum up, the top pressure opening structure of the slide rail of the present invention can easily open and lock the cabinet drawers by virtue of the top pressure control, and the designed fool-proof opening structure can prevent the slide rail from being damaged.
