Problems solved by technology

[0002] At present, the interlocking transmission of the drawers in the switchgear has many forms, such as the interlocking mechanism that is directly pushed and pulled out by hand, which is based on the intermeshing of the gear and the rack installed on the interlocking installation plate and the handle of the control gear through the connecting piece. Control the two saw-toothed locking bars pivotally mounted on the drawer body of the switch cabinet to run relatively axially, so as to lock the drawer in the isolation, test and connection positions. Although this method can lock the drawer and display it in the working position , testing, extraction or other stations, but the use of gear transmission positioning makes the overall volume of the transmission part increase, occupying the installation position of the instrument panel, and the material requirements for gear processing will be relatively high. Generally, zinc alloy is used. Moreover, multiple operations will cause wear and teeth gnashing, and need to be replaced frequently, which increases the production cost

Embodiment Construction

[0016] Such as figure 1 , figure 2 , image 3 , Figure 4 The switch cabinet drawer interlocking mechanism shown includes a rotating shaft 2 pivotally mounted on the drawer body 1, a handle 3 disposed on the rotating shaft 2, and two locking locks with sawtooth pivotally mounted on the drawer body 1. Bar 4, the two locking bars 4 form a relative axial movement through the linkage with the rotating shaft 2. The rotating shaft 2 and the two locking bars 4 are linked through an interlock mechanism 5. The interlock mechanism 5 includes a The transmission block 51, the limit piece 52 that constitutes the multi-position limit of the transmission block 51, the swing arm 53 that is connected with the transmission block 51 and is swinging, and the swing arm 53 is connected with any locking bar 4. In the linkage mechanism 5, the drive block 51 is driven by the rotating shaft 2, and the drive block 51 drives the swing arm 53 to swing, and the swing arm 53 drives the locking bar 4 to ...
