Description
Technical field
The utility model relates to door interlock in a kind of mid-cabinet, is applicable to the interlocking device of the mid-handcart cabinet of withdraw-type.Belong to handcart cabinet electric fittings technical field.
Background technology
At present, the mid-handcart cabinet of withdraw-type is widely used.But the mid-handcart cabinet of the withdraw-type of prior art all is not provided with middle door interlock.There is following shortcoming in this mid-handcart cabinet: (1) when handcart was in the service position, middle door can be opened arbitrarily, causes security incident easily.(2) in the running of handcart cabinet, because the needs of various detections or maintenance often require to open middle door.When switchgear during in running status, promptly need middle door to be opened with specific purpose tool, this is a comparatively complicated operations process, often because operation or improper use cause device damage or cause security incident.
The utility model content
The utility model technical issues that need to address, i.e. the purpose of this utility model is for door interlock in a kind of mid-cabinet being provided, both having overcome the defective that middle door can be opened arbitrarily, can make things convenient for again, safe release.
Technical problem of the present utility model can solve by following measure: door interlock in a kind of mid-cabinet, its design feature is: in the mid-handcart cabinet of withdraw-type preceding, between door and the internal chamber wall interlock is set, this device mainly comprise power transmission shaft guide plate, power transmission shaft, braking roll, preceding in a stopper, connecting axle, connecting lever bearing, rocking arm and connecting lever; The power transmission shaft guide plate is fixed on the intracavity sidewall of handcart cabinet, power transmission shaft is positioned at the gathering sill of power transmission shaft guide plate, the front end of power transmission shaft is continuous with preceding middle door by braking roll, the rear end connecting axle is connected with rocking arm; the other end of rocking arm is connected with connecting lever by hinge; the connecting lever bearing is fixed on the madial wall of mid-handcart cabinet; the middle part of rocking arm is connected with the connecting lever bearing by hinge, and a preceding middle door stopper clogs unlock hole.
The utlity model has following outstanding effect:
1, the utility model is owing to be provided with middle door interlock cashier's office in a shop at the mid-wheelbarrow switch of withdraw-type, therefore, when handcart is in the service position in door can not open, overcome the defective that door can be opened arbitrarily in the withdraw-type of prior art.
2, because middle door interlock is provided with emergency release, therefore, in the time of need opening middle when being in an emergency, the interlocking of door need not specific purpose tool in can removing by emergency release, and is safe, simple, convenient, fast.
3, one of the utility model characteristics are to be provided with control device at the Qianmen of equipment, the effect of this device is as after front door lock is opened with specific purpose tool, just can open after operating this device, the top of this device is provided with spacing hole that cooperates with device in the equipment and the release that is used for the spacer pin of device in the releasing equipment and uses the hole.Usually under the state on the Qianmen emergency release cover with special cap with the hole.
4, two of the utility model characteristics is to be provided with control device in cabinet, acting as when the Qianmen is in closed condition and locks of this device, as handcart in the equipment from the test position to the service position, in the spacing hole on the cover linkage drive spacer pin insertion Qianmen, the device action of calling before the restriction, handcart is in the service position in the equipment thereby reach, and the purpose of door can not be opened in the Qianmen under the Explosion-proof Lock disarm state.Under abnormal condition, in the time of can not returning because of the service position as handcart in the equipment, because the special construction on the spacer pin, remove on the Qianmen emergency release with the special cap on the hole, unload spacer pin with screwdriver, the Qianmen lock-out state is removed, and the Explosion-proof Lock of outwarding winding can be opened the Qianmen, in case abnormal condition is removed, should recover in the equipment immediately and interlock on the Qianmen.

Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structure right view of the utility model embodiment 1.
Embodiment
Fig. 1, Fig. 2 constitute embodiment 1 of the present utility model.As can be seen from Figure 1, present embodiment mainly comprises power transmission shaft guide plate 1, power transmission shaft 2, braking roll 3, preceding middle door stopper 4, connecting axle 6, connecting lever bearing 7, rocking arm 8 and connecting lever 9; Power transmission shaft guide plate 1 is fixed on the intracavity sidewall of handcart cabinet 10, power transmission shaft 2 is positioned at the gathering sill of power transmission shaft guide plate 1, the front end of power transmission shaft 2 by braking roll 3 with preceding in door 5 link to each other, rear end connecting axle 6 is connected with rocking arm 8; other end of rocking arm 8 is connected with connecting lever 9 by hinge; connecting lever bearing 7 is fixed on the madial wall of mid-handcart cabinet 10; middle part of rocking arm 8 is connected with connecting lever bearing 7 by hinge, and a preceding middle stopper 4 clogs unlock hole.
In the present embodiment: power transmission shaft guide plate 1 usefulness sunk screw is fixedly mounted on the equipment interior plate, in order to supporting drive shaft 2, braking roll 3 is assemblied on the power transmission shaft 2, middle 5 emergency release hole before 4 shutoff of door stopper in preceding, connecting axle 6 is contained on the power transmission shaft 2, connecting lever bearing 7 is as the strong point of rocking arm 8, concrete transmission process is: when handcart enters the service position, connecting lever 9 is depressed; rocking arm 8 moves in the direction of the clock, and power transmission shaft 2 and assembling braking roll 3 thereon are in direction is outdoors released the interlocking hole of inserting the door upper slide, and this moment, a door upper slide can not move up; the gathering sill small end is in the guide finger gathering sill to deviate from the slide plate, and door is locked.When handcart was return test position, connecting lever 9 resetted, and rocking arm 8 is by counterclockwise rotating, braking roll 3 direction in door that drives power transmission shaft 2 and assemble on it replys outside the interlocking hole of a upper slide, slide plate can move up and make gathering sill break away from guide finger, at this moment outwards pulls, and door can be opened.In case of emergency, remove a last stopper 4, lay down braking roll from unlock hole with screwdriver, the lock-out state of door is disengaged, and door can be opened in the test position method of operation by handcart.
The specification requirement of present embodiment is as follows:
1, assembling should meet the general assemble condition.
2, when handcart is in test position, middle door can be opened, and when handcart was in the service position, closed condition can not be opened, be in to middle door.
