Abstract

An operative coupling and interlocking device of a drawer rail comprises an operative coupling board base mounted to a rear end of a bottom rail. The operative coupling board base receives a hook bar and operative coupling boards to respectively insert them into a middle portion and upper and lower sides thereof. The operative coupling board base also receives in an interior thereof a slide block that is slidable frontward and rearward. The slide block has opposite sides that form slopes that respectively push, in a frontward direction, the two operative coupling boards to move outward. The slide block and the hook bar are movable in unison. A spring is arranged between the slide block and the operative coupling board base. The bottom rail comprises a slidable rail mounted thereto and engageable with and driving the hook bar frontward. When the slidable rail of the present invention is moved frontwards and engages and drives the hook bar frontward, the slidable block may push the two operative coupling board outward with an increased extent. Further, the operative coupling boards have enlarged surface area and can thus smoothly slide. When a plurality of the present inventions are used in a vertical cascade manner, a bettered effect of locking can be achieved.

Description

Drawer slide linkage interlocking device

The invention relates to a structure of a slide rail, in particular to a drawer slide interlocking interlocking device.

The existing drawer slide rail, as shown in FIG. 7, is provided with a bottom rail 70, and a linkage plate base 71 is fixed at the rear end portion of the bottom rail. The middle of the linkage plate base 71 is extended in the front and rear directions. The linear hole portion 711 further extends downward at the front end of the linear hole portion 711 to form a fastening hole portion 712, and the upper and lower sides of the interlocking plate base 71 are located upward and downward on the upper and lower sides of the fastening hole portion 712. A latching block 72 is fastened to the upper and lower sides of the bottom rail 70 by the respective engaging projections 72, and a through-bar perforation 721 is vertically penetrated in the middle of each of the engaging projections 72, and the perforated rod perforated 721 A linkage rod 73 is disposed in a movable upper and lower movement manner, and a triangular insertion block 731 is formed at one end of each linkage rod 73 in the bottom rail 70. The two insertion blocks 731 extend toward the top rod 732, and when the two linkages are linked When the rods 73 are close to each other, the inner ends of the two top rods 732 are abutted against each other; and a sliding card block 74 is disposed in a form in which the portion of the interlocking plate base 71 between the two engaging projections 72 is slidable forward and backward. A spring 741 is coupled between the rear end of the slide card block 74 and the rear end of the link plate base 71, and is also at the rear end of the slide card block 74. A fastening hole 742 is defined. The fastening hole 742 is a long hole extending in the upper and lower directions. A hook 75 is slidably disposed in the linear hole portion 711 and the fastening hole portion 712 of the linkage plate base 71. The inner end of the hook 75 protrudes inwardly and passes through the buckle hole 742 inwardly, and a triangular cavity is recessed in the shape of each of the insert blocks 731 on the upper and lower sides of the front end portion of the sliding block 74. 743; A rear rail 76 is disposed on the inner side of the bottom rail 70 in a front and rear sliding manner, a front rail 77 is disposed on the inner side of the rear rail 76, and a hooking groove 771 is obliquely opened on the rear end surface of the front rail 77. The hooking groove 771 can hook the inner end of the hook 75, and the hook 75 is pulled forward from the straight hole portion 711 to the position of the hooking hole portion 712, so that the sliding card block 74 moves forward relative to the linking plate base 71 and In the fixed position, at this time, the upper and lower edges of the slide card block 74 will eject the interlocking lever 73 in the upward and downward directions, respectively.

When the existing drawer slide rails are arranged, as shown in FIG. 8, the drawer slide rails are arranged in pairs on the left and right sides, and the drawers are combined on the inner side of the front rails 77 of the pair of drawer slide rails, and the slide rails of each drawer are also arranged. The upper and lower positions are provided with other drawer slide rails, and the adjacent linkage rods 73 are connected in series between the upper and lower drawer slide rails, so that the pairs of drawer slide rails are arranged in a chain between upper and lower. .

When the existing drawer slide rail is used, as shown in FIG. 8 and FIG. 9, when one of the drawers is pulled forward, the hooking groove 771 of the front rail 77 pulls the hook 75 forward, and the hook 75 will follow. When the straight hole portion 711 moves forward, the slide card block 74 is moved forward, and finally the hook bar 75 is moved to the front end of the straight hole portion 711 and falls into the buckle hole portion 712 for positioning, thereby simultaneously fixing the position of the slide card block 74.

During the forward movement of the slide card block 74, the upper and lower sides of the slide card block 74 are also moved forward from the position of the linkage rod 73, and then the upper and lower edges of the slide card block 74 will be The two linkage rods 73 are respectively top and bottom, and the interlocking rod 73 that is ejected is moved by the rod body to interlock the linkage rods 73 of the upper and lower adjacent drawer slide rails, and one of the linkage rods 73 of the adjacent drawer slide rails is again The other linkage rod 73 is ejected by the ejector rod 732, so that the linkage rods 73 of the other drawer slide rails can clamp the position of the sliding card block 74 in such a manner. The front rails 77 of the other drawer slides are fixed by the hooks 75 to achieve the function of pulling only one drawer at a time.

Although the foregoing conventional drawer slide rail can achieve multiple sets of settings, only one drawer can be pulled forward at a time, but since the insert block 731 of the linkage rod 73 of each drawer slide rail is inserted into the slide card block 74 The side of the pocket 743, and the width of each of the sliding blocks 74 is limited, so that the depth of each of the pockets 743 is limited, and the width of the interlocking rod 73 is pushed outward to a smaller extent. Further, the linkage rod 73 is a rod. The movement mode in which the linkage rods 73 are inserted into the linkage rod perforations 721 and can slide up and down lacks guidance, so that the movement of the linkage rods 73 is less stable, so that the linkage rods 73 of the existing drawer slide rails cannot be compared. Smooth and reliable chain driving effect.

Since the two linkage rods of the existing drawer slide rail are configured as a rod body, the guide is lacking and the action range is small, so that the action is less smooth.

In the present invention, since the two interlocking elements 40 are opened forward by the sliding block 30, the depth of insertion of the two interlocking elements 40 into the sliding block slot 212 is not limited by the width of the sliding block 30, so that it can be set to a deeper shape. The sliding block 30 can push the linking member 40 out for a long stroke. Further, as shown in FIG. 1, since the leading edge of each of the linking plate perforations 231 is provided with a guiding ejector guiding groove 232, the engaging interlocking member 40 is at the leading edge. The ejector rod 42 is provided to be movable by the ejector rod 42 sliding up and down along the ejector guiding groove 232, so that the sliding block 30 can move the linking member 40 up and down in a relatively stable and smooth manner. This can be achieved by a plurality of interlocking movement interlocking elements 40 between the present invention to achieve a better effect of moving stable and indeed locking the sliding block 30.
