Abstract
The invention relates to a mechanical interlocking device between a handcart and a back door. The mechanical interlocking device between the handcart and the back door is simple in structure due to ingenious arrangement of the structure. According to the mechanical interlocking device between the handcart and the back door, a mechanical interlocking mode is adopted to achieve the matching of relevant parts, and then the effect that the back door is opened only under the condition that the handcart returns to a test position and the handcart can enter a working position only under the condition that the back door is completely closed is achieved. The mechanical interlocking device between the handcart and the back door has the advantages of being compact in structure, simple, practical, easy and convenient to operate, long in service life and the like.
Description
Technical field
The present invention relates to the mechanical interlocks at a kind of handcart and back door, it is mainly used in the mid-cabinet.
Background technology
Do not have earthed switch in the mid-cabinet, in order to guarantee the safety of operating personnel and equipment, must possess following function, namely have only handcart to fall back on test position, just the back door can open, otherwise, have only when the back door and close fully, handcart just can enter the service position; As the interlock not having, being easy to produce relevant issues, existing interlock is generally electric, and its reliability is relatively poor, and damages easily, and the life-span is shorter.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of mechanical interlock, and it has compact conformation, characteristics such as long service life.
The technical solution used in the present invention is for this reason: comprise front side board (7), front side board (7) is provided with left location notch and right location notch, and described left location notch, right location notch can pass through operating handle (16);
The rear end of operating handle (16) arranges one can be by the front axle (10) of its compacting, the operating axis (4) that the rear end of described front axle (10) is provided with and front axle (10) cooperates and can be driven rotation by it, described front axle (10), operating axis (4) connect by briquetting (11), front axle (10) is gone up outer sheathed stage clip one (8), and this stage clip (8) supports and is located on the briquetting (11);
Operating axis (4) rear end sets gradually interlocking segment (3) and rear door buckling (2), wherein be connected with on the interlocking segment (3) with operating axis (4) interlock block shaft (12), the block (14) that this block shaft (12) is provided with stage clip two (13) and is supported by stage clip two (13), block shaft (12) is blocked by the back door and suppressed by it; The locked groove that described snap close (2) and be arranged on back door locking plate (1) correspondence that plays on the back door back door locking effect, this back door locking plate (1) are provided with and snap close (2) is corresponding;
Front side board (7) is provided with slide down moving part (9), and this slide down moving part (9) connects the handcart guide rail, and the block piece that slide down moving part (9) is made up of briquetting (11), front axle (10) is spacing.
Advantage of the present invention is: interlock of the present invention is mechanical type, and by structure setting cleverly, it has the characteristics of compact conformation, and it mainly adopts mechanically linkage manner, realizes the cooperation of each associated components, thereby realize having only handcart to fall back on test position, the back door just can be opened, otherwise, have only when the back door and close fully, handcart just can enter the function of service position, and it has compact conformation, simple and practical, characteristics such as operation is light, life-span length.
Description of drawings
Structural representation when Fig. 1,2,3 is in manual experiment for the present invention.
Fig. 4,5,6 is in the structural representation of handcart service position for the present invention.
1 is that back door locking plate, 2 is that snap close, 3 is that interlocking segment, 4 is that operating axis, 5 is that fixed block, 6 is that fixed support, 7 is that front side board, 8 is that stage clip one, 9 is that slide down moving part, 10 is that front axle, 11 is that briquetting, 12 is that block shaft, 13 is that stage clip two, 14 is that block, 15 is that support, 16 is operating handle among the figure.
Embodiment
Structure of the present invention is as follows: support 15 is fixed on front side board 7 rear sides, and fixed support 6 is fixed on front side board 7 front sides, and operating axis 4 front and back are separately fixed on front side board 7 and the support 15 by fixed block 5.
Operate as follows: handcart is when test position, press slide down moving part 9 and expose handle hole, the bossing of operating handle 16 is aimed at the location notch hole on front side board 7 left sides, and push down the front end that front axle 10 inserts operating axis 4, make it to withdraw from the location notch hole of front side board 7, clockwise rotate 120 degree then, make the location notch hole on bossing aligning front side board 7 the right of operating handle 16, extract operating handle 16, make front axle 10 under the pressure effect of stage clip 1, stretch out outside the front side board 7, and be fixed on this position.Push down slide down moving part 9 after briquetting 11 rotations simultaneously, make slide down moving part 9 can not on move.When slide down moving part 9 moves down, drive the latch fitting that the is associated car guide rail that reaches, thereby stop handcart to be pushed into the service position from test position.
Snap close 2 is under the rotation of operating axis 4 drives, 120 degree turn clockwise, leave the locked groove of back door locking plate 1 on the back door, open at the back door, block shaft 12 is stretched out outside the cabinet under the pressure effect of stage clip 2 13 simultaneously, block 14 moves to interlocking segment 3 with block shaft 12 and is in same plane, because interlocking segment 3 is blocked by block 14, operating axis 4 can not be rotated counterclockwise.
Have only when the back door drives back door locking plate 1 and close fully, push down block shaft 12, and block 14 and interlocking segment 3 are staggered, the bossing of operating handle 16 is aimed at the slotted eye on front side board 7 the right and pushed down front axle 10, make front axle 10 under the pressure of stage clip 1, withdraw from the slotted eye on the right and be rotated counterclockwise 120 and spend, be fixed in the slotted eye on its left side, extract operating handle 16 then.Snap close 2 inserts in the locked groove of back door locking plate 1 under the rotation of operating axis 4 drives, and pins the back door.
After briquetting 11 was rotated counterclockwise 120 degree with operating axis 4, it can not push down slide down moving part 9, and slide down moving part 9 moves under the drive of the latch fitting that is associated, and drives locking part and withdraws from the handcart guide rail, and handcart can be moved to the service position.Because the locking part that is connected with slide down moving part 9 is blocked by the baffle plate on the handcart, slide down moving part 9 can not be pressed, so this device can not be operated, and the back door can not be opened.
