Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple and compact for structure, and easy to operate, good stability can satisfy the drawer unit interlock of people's instructions for use.
In order to solve the problems of the technologies described above, drawer unit interlock of the present utility model comprises by the middle part jointed shaft and is hinged on a lever on the shell body, shell body is fixedly mounted on the drawer-bottom board, be provided with the lock hole of separation, experiment, three stations of combined floodgate on the drawer-bottom board, the front end below of lever is provided with the roller that can enter in the lock hole; Being provided with between described lever leading portion top and the shell body makes roller be positioned at the Compress Spring of lock hole under lock-out state; Described lever back segment top is provided with a slide block that is installed on the drawer panel and can horizontally slips, and described slide block bottom surface is pressed on the lever back segment, and horizontally slipping of slide block can press lever, makes the roller of lever front end lift or fall.
Have the first darker groove of the degree of depth and the second more shallow groove of the degree of depth on the bottom surface of described slide block, be provided with one section inclined-plane between the first groove and the second groove, the roller of lever front end can fall when the lever back segment was aimed at the first groove, and the roller of lever front end was lifted when the lever back segment was aimed at the second groove.
When described lever back segment was aimed at the second groove, the height that roller lifts made roller portion be arranged in lock hole and can leave lock hole by rolling; And when roller was rolled into drawer-bottom board surperficial, the back segment of lever was positioned at the position that breaks away from the second groove.
Between the standing part of described slide block and drawer panel back-moving spring is installed, the spring force direction of back-moving spring is to make slide block move to the position that the first groove is aimed at lever.
Described slide block is housed in the cover body, and described cover body is fixed on the drawer panel, and described back-moving spring is installed between slide block and the cover body inwall.
The described slide block outside is equipped with one and pushes away and turn round.
After adopting above-mentioned structure, because the lever that arranges and can make lever swing and when promoting, can make roller enter into slide block in each lock hole along jointed shaft, the mode of stirring about employing makes roller can place separation, experiment, three stations close a floodgate, and the function that has automatically locking and reset, arrange thus, effective installing space simple and compact for structure, that take drawer unit is little, easy to operate, good stability, can there be the problem of seeking chain lock hole moving forward and backward in the process of drawer unit, therefore can satisfies people's instructions for use.

Embodiment
Below in conjunction with the drawings and specific embodiments, drawer unit interlock of the present utility model is described in further detail.
As shown in the figure, the drawer unit interlock of the utility model embodiment comprises by middle part jointed shaft 1 and is hinged on a lever 2 on the shell body 3, shell body is fixedly mounted on the drawer-bottom board 11, be provided with the lock hole 10 of separation, experiment, three stations of combined floodgate on the drawer-bottom board, the front end below of lever 2 is provided with the roller 4 that can enter in the lock hole; Be provided with the Compress Spring 5 that under lock-out state, makes roller 4 be positioned at lock hole between described lever 2 leading portions top and the shell body 3; Described lever 2 back segment tops are provided with a slide block 6 that is installed on the drawer panel and can horizontally slips, and described slide block 6 bottom surfaces are pressed on lever 2 back segments, and horizontally slipping of slide block can press lever, makes the roller of lever front end lift or fall.Have the first darker groove 7 of the degree of depth and the second more shallow groove 8 of the degree of depth on the bottom surface of slide block 6, be provided with one section inclined-plane 9 between the first groove and the second groove, the roller 4 of lever front end can fall when the lever back segment was aimed at the first groove 7, and the roller 4 of lever front end was lifted when the lever back segment was aimed at the second groove 8.
When the lever back segment was aimed at the second groove 8, the height that roller 4 lifts made roller portion be arranged in lock hole 10 and can leave lock hole by rolling; And when roller was rolled into drawer-bottom board 11 surperficial, the back segment of lever was positioned at the position that breaks away from the second groove 8.
Back-moving spring 12 is installed between the standing part of slide block 6 and drawer panel, and the spring force direction of back-moving spring 12 is to make slide block 6 move to the position that the first groove is aimed at lever.
Slide block is housed in the cover body 13, and described cover body 13 is fixed on the drawer panel, and described back-moving spring 12 is installed between slide block and the cover body inwall.
The below illustrates operation principle of the present utility model take the action of the utility model embodiment in the drawer unit push-on process as example:
During beginning, drawer unit is positioned at the separation point position, and this moment, lever 2 back segments were arranged in the first groove 7, and the roller 4 of lever front end drops in lock hole corresponding to separation point position 10 fully, and drawer unit can't advance; At this moment, operate slide blocks to a Slideslip by push button 14, the lever back segment 9 is relatively moved along the inclined-plane, thereby the roller of lever front end is lifted, until the lever back segment enters the second groove 8, make slide block and lever all limited, only there is part to be positioned at lock hole 10 at this position roller, can promote forward drawer unit this moment, make roller 4 leave lock hole 10 by rolling and arrive the drawer-bottom board surface, this moment, the lever back segment broke away from the second groove 8, and slide block 6 loses mutually spacing with lever 2, slide block moves to the position of beginning under the spring-force driven dual of back-moving spring 12, the first groove 7 is aimed at the lever back segment again;
When drawer unit was pushed into test position, the roller 4 of lever front end fell into again to lock hole 10 corresponding to test position, and drawer unit is again locked and can't advance; Repeat last operating procedure this moment, just drawer unit can be advanced into closing position.
The process that withdraws from of drawer unit is identical with above-mentioned push-on process mode of operation, and the moving direction of drawer unit only is opposite.
