Detailed description of the invention
Referring to figs. 1 through Fig. 2, this utility model embodiment is described further。
Present embodiment discloses a kind of Novel interlocking mechanism, as it is shown in figure 1, include earthing operation axle 1, earthing operation axle 1 rotates when earthing divide-shut brake；Described earthing operation axle 1 is fixed with cam 2, described cam 2 is conflicted and is connected to pressing plate 3, the lower section of described pressing plate 3 is fixedly connected with drive link 6, described drive link 6 is arranged with mounting seat 4, described mounting seat 4 is fixed on the housing of switch cubicle, is provided with the spring 5 promoting drive link 6 to reset between described mounting seat 4 and pressing plate 3, and spring 5 is sheathed on drive link 6, the end of described drive link 6 is rotatably connected to connecting rod, and the middle part of described connecting rod is provided with rotating fulcrum 9；The other end that described connecting rod is connected with drive link 6 is provided with locked groove 10, the U-shaped structure of locked groove 10, and the front lower door-plate 12 of switch cubicle is provided with the locking bolt 11 of cylinder, and earthing operation axle 1 band moving cam 2 rotation control locked groove 10 is sealed with locking bolt 11 or separates。
Illustrate below in conjunction with use state: when switch cubicle is in normal operating condition, earthing is in separating brake, cam 2 is set to the state of extruding pressing plate 3 by original state, drive link is pressed for 6 times, and make one end that connecting rod is provided with locked groove 10 lift with locking bolt 11 formed coordinate, now front lower door-plate 12 cannot be opened, and plays the effect of security protection；When overhauling, open front lower door-plate 12 to be necessary for first being closed a floodgate by earthing, operated axle 1 by earthing and rotate the releasing cam 2 squeezing action to pressing plate 3 with moving cam 2, now pressing plate 3 be subject to spring 5 effect drive drive link 6 lift, one end that drive link 6 is connected with connecting rod is lifted, owing to being provided with rotating fulcrum 9 in the middle part of it in lever construction, now it is provided with one end of locked groove 10 just away from locking bolt 11, it is achieved thereby that the unblock of front lower door-plate 12。
Effect of the present utility model is in that, relative to prior art, its structure is relatively simple, and parts are less, and convenient installation, cost is relatively low。
It addition, for the switch cubicle of different model, there is the situation that earthing operation axle 1 position is different, it is preferred that as it is shown in figure 1, described connecting rod offers some installing holes 8 for connecting drive link 6 along its length。By adopting such scheme, the convenient link position regulated between drive link 6 and connecting rod, then coordinate the installation site changing mounting seat 4, so that pressing plate 3 and cam 2 are conflicted, to use suitable in the switch cubicle of different model better。
