The utility model is used for a drawing cabinet with multiple layers.

Description

Can realize the railroad of drawer interlocking

Technical field

The utility model relates to a kind of drawer slide rail, particularly a kind of railroad of realizing the drawer interlocking.

Background technology

Traditional drawer slide rail is not provided with mutual interlocking gear, and the upper and lower drawer of cabinet can all outwards be pulled out simultaneously, mutually without any influence.For higher or bigger file cabinet, if simultaneously a plurality of drawers are outwards pulled out, may cause cabinet to topple over, jeopardize user's safety.The present inventor has proposed a kind of technical scheme that addresses the above problem through years of researches, in use reaches very desirable effect, can limit drawer and outwards pull out simultaneously, avoids occurring the phenomenon appearance that cabinet is toppled over, protection user safety.

Summary of the invention

The purpose of this utility model is to provide a kind of and prevents that cabinet from toppling over, a kind of railroad of realizing the drawer interlocking easy to use.

The purpose of this utility model is achieved in that a kind of railroad of realizing the drawer interlocking, can form along the movable slide rail that this fixed rack slides by fixed rack and at least one, wherein: an end of described fixed rack is provided with locating piece, the locating piece middle part is provided with and the consistent chute of movable slide rail moving direction, is provided with mutual correspondence and the push rod mounting groove vertical with chute in the locating piece on chute both sides; Be provided with slide block in chute, the front part sides of slide block is the inclined-plane, is provided with push rod in the push rod mounting groove, and the inclined-plane contact-making surface of push rod and slide block front portion also is the inclined-plane, and the push rod end on both sides offsets; Be provided with shift fork on slide block top, an end and the locating piece of shift fork are hinged, are dynamically connected by bearing pin between shift fork and the slide block, are provided with extension spring between shift fork and locating piece, are provided with shifting block in the movable slide rail end corresponding with shift fork.

Chute middle part described in the railroad of the above-mentioned drawer realized interlocking is provided with the guiding convex tendon, is provided with block in the chute outer end.

After the utility model adopted said structure, push-and-pull activity slide rail can the interlock shift fork, drove slide block and moved in chute, thereby change the relative position of push rod, realized once pulling out a drawer, prevented the purpose that cabinet is toppled over.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of railroad of realizing the drawer interlocking of the present utility model, can form along the movable slide rail 2 that this fixed rack 1 slides by fixed rack 1 and two, left end at fixed rack 1 is provided with locating piece 3, locating piece 3 middle parts are provided with and the consistent chute 31 of movable slide rail 2 moving directions, be provided with guiding convex tendon 33 at chute 31 middle parts, slide block 4 is moved steadily; Be provided with block 34 in chute 31 outer ends, be used to limit slide block 4 and skid off chute 31.In the locating piece 3 on chute 31 upper and lower both sides, be provided with mutual correspondence and the push rod mounting groove 32 vertical with chute 31; Be provided with slide block 4 in chute 31, the front part sides of slide block 4 is inclined-plane 41, is provided with push rod 5 in push rod mounting groove 32, and push rod 5 also be inclined-plane 51 with inclined-plane 41 contact-making surfaces of slide block 4 front portions, and the push rod on upper and lower both sides 5 offsets the formation interlock in the end; Be provided with shift fork 6 on slide block 4 tops, an end and the locating piece 3 of shift fork 6 are hinged, are dynamically connected by bearing pin 7 between shift fork 6 and the slide block 4, are provided with extension spring 8 between shift fork 6 and locating piece 3, are provided with shifting block 21 in movable slide rail 2 ends corresponding with shift fork 6.Pulling out movable slide rail 2 can interlock shift fork 6, drives slide block 4 and moves right in chute 31, and push rod 5 is withstood in slide block 4 two sides, and push rod 5 can not upper and lowerly be moved, and presents the state among Fig. 1, limits another group drawer and opens.Push move movable slide rail 2 can interlock shift fork 6, driving slide block 4 is moved to the left in chute 31, top push rod 5 is under the effect of own wt, the inclined-plane 51 of bottom contacts with the inclined-plane 41 of slide block 4 upsides, upper and lower push rod 5 all can upper and lowerly move, present the state among Fig. 2, another group drawer can be opened.

State when the utility model specifically uses is represented one or four layers of drawout cubicle among the figure as shown in Fig. 3 to Fig. 7, Fig. 3 shows the state that four layers of drawer are not all opened; Fig. 4 shows the 4th layer of drawer unlatching of topmost, and push rod 5 is lockable, and its excess-three layer drawer of bottom can not be opened; Fig. 5 shows the 3rd layer of drawer unlatching on top, and push rod 5 is lockable, and its excess-three layer drawer can not be opened; Fig. 6 shows the second layer drawer unlatching on top, and push rod 5 is lockable, and its excess-three layer drawer can not be opened; Fig. 7 shows the ground floor drawer unlatching of foot, and push rod 5 is lockable, and its excess-three layer drawer can not be opened.
