Description
Technical field
The present invention relates to a kind of drawer unit interlock that is used for low-voltage complete equipment drawer-type switch cabinet, belong to the low-voltage distribution apparatus technical field.
Background technology
Drawer-type switch cabinet in use all will pass through the operation of separation, experiment, three stations of combined floodgate in the low-voltage complete equipment; Existing drawer-type switch cabinet is not owing to there is reliable lock hole; Therefore can there be potential safety hazard in operating personnel in operating process; Afterwards for therefore the handling safety that guarantees operating personnel has adopted interlocking gear to realize the operational lock hole of separating, test, closing a floodgate three stations, however existing drawer unit interlocking gear is general adopt about the mode that locks up and down of locking or steel wire rope, employing has such interlock now; Because the setting of structure itself, the convenience that makes its stability and operation is not very desirable; Adopt existing such mechanism's volume very big simultaneously, take effective installing space of drawer unit, therefore existing this interlocking gear can not satisfy people's instructions for use.
Summary of the invention
The technical problem that the present invention will solve 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 invention comprises through 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; Drawer-bottom board is provided with separation, experiment, the lock hole of three stations that close a floodgate, and the front end below of lever is provided with the roller that can enter in the lock hole; Be provided with the compression spring that under lock-out state, makes roller be positioned at lock hole between said lever leading portion top and the shell body; Said lever back segment top is provided with a slide block that is installed on the drawer panel and can horizontally slips, and said 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 first darker groove of the degree of depth and the second more shallow groove of the degree of depth on the bottom surface of said slide block; Be provided with one section inclined-plane between first groove and second groove; The roller of lever front end can fall when the lever back segment was aimed at first groove, and the roller of lever front end was lifted when the lever back segment was aimed at second groove.
When said lever back segment was aimed at second groove, the height that roller lifts made roller portion be arranged in lock hole and can leave lock hole through 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 second groove.
Between the standing part of said 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 first groove is aimed at lever.
Said slide block is housed in the cover body, and said cover body is fixed on the drawer panel, and said back-moving spring is installed between slide block and the cover body inwall.
The said slide block outside is equipped with one and pushes away and turn round.
After adopting above-mentioned structure; Because the lever that is provided with and can make lever along the jointed shaft swing and when promoting, can make roller enter into the slide block in each lock hole; The mode of stirring about employing makes roller can place separation, experiment, three stations of combined floodgate, and the function that has automatically locking and reset, and is provided with thus; Effective installing space simple and compact for structure, that take drawer unit is little; Can there be the problem of seeking chain lock hole in easy to operate, good stability moving forward and backward in the process of drawer unit, therefore can satisfy people's instructions for use.

Embodiment
Below in conjunction with accompanying drawing and embodiment, drawer unit interlock of the present invention is done further explain.
As shown in the figure; The drawer unit interlock of the embodiment of the invention comprises through 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; Drawer-bottom board is provided with separation, experiment, the lock hole 10 of three stations that close a floodgate, and the front end below of lever 2 is provided with the roller 4 that can enter in the lock hole; Be provided with the compression spring 5 that under lock-out state, makes roller 4 be positioned at lock hole between said lever 2 leading portions top and the shell body 3; Said lever 2 back segment tops are provided with a slide block 6 that is installed on the drawer panel and can horizontally slips, and said 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 and the second more shallow groove 8 of the degree of depth of the degree of depth on the bottom surface of slide block 6; Be provided with one section inclined-plane 9 between first groove and second groove; The roller 4 of lever front end can fall when the lever back segment was aimed at first groove 7, and the roller 4 of lever front end was lifted when the lever back segment was aimed at second groove 8.
When the lever back segment was aimed at second groove 8, the height that roller 4 lifts made roller portion be arranged in lock hole 10 and can leave lock hole through 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 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 first groove is aimed at lever.
Slide block is housed in the cover body 13, and said cover body 13 is fixed on the drawer panel, and said back-moving spring 12 is installed between slide block and the cover body inwall.
Be example with the action of the embodiment of the invention in the drawer unit push-on process below, operation principle of the present invention be described:
During beginning, drawer unit is positioned at the separation point position, and this moment, lever 2 back segments were arranged in first groove 7, and the roller 4 of lever front end drops in the corresponding lock hole 10 in separation point position fully, and drawer unit can't advance; At this moment, it is moving to break away to one through push button 14 operation slide blocks, and the lever back segment 9 is relatively moved along the inclined-plane; Thereby the roller of lever front end is lifted, get into second groove 8, make slide block and lever all limited until the lever back segment; Only have part to be positioned at lock hole 10 at this position roller, can promote drawer unit forward this moment, makes roller 4 leave lock hole 10 through rolling and arrive the drawer-bottom board surface; This moment, the lever back segment broke away from second groove 8; Slide block 6 and lever 2 lose spacing each other, and slide block moves to the position of beginning under the spring force effect of back-moving spring 12, and 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 the corresponding lock hole 10 of test position, and drawer unit is locked once more and can't advances; Repeat last operating procedure this moment, just can drawer unit 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.
