Abstract

The invention discloses a door locking mechanism of a high-voltage switch cabinet, which comprises a rotating arm capable of driving a movable door to move, wherein the tail end of the rotating arm is articulated with the rear downside of a handcart frame; the front upside of the handcart frame is articulated with an interlocking baffle; a hook is fixedly mounted on the interlocking baffle; a buckle fixedly mounted on a door body and matched with the hook is arranged at the front of the hook; a connecting rod arranged in the longitudinal direction of the handcart frame is articulated between the rotating arm and the interlocking baffle; and the connecting rod can drive the interlocking baffle to move to lock the hook in the buckle under the driving of the rotating arm. With the adoption of the structure, when a handcart is cranked to a working position from a testing position, the rotating arm moves, the movable door is opened, and the connecting rod drives the interlocking baffle to move to lock the hook in the buckle under the driving of the rotating arm, so that a door locking function is achieved, and the door locking mechanism is simple in structure and reliable to operate, and prevents potential safety hazards caused by door opening due to misoperation.

Description

The high-tension switch cabinet lock door mechanism
 
Technical field
The present invention relates to the interlocking device that uses in a kind of high pressure complete set of equipments, specifically a kind of high-tension switch cabinet lock door mechanism.
Background technology
At present the high-tension switch cabinet produced of domestic manufacturer is not installed lock door mechanism, when handcart when test position is shaken into the service position, door can be opened in the handcart, has potential safety hazard in case there is the people that door is opened the misoperation meeting.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, operation is reliable, prevents the high-tension switch cabinet lock door mechanism that misoperation is opened the door after can making handcart enter into the service position.
In order to solve the problems of the technologies described above, high-tension switch cabinet lock door mechanism of the present invention, comprise a pivoted arm that can drive valve action, the end of pivoted arm is hinged on the back lower place of cart frame, the front upper place of described cart frame is hinged with an interlocking baffle plate, hook of fixed installation on the interlocking baffle plate, the place ahead of hook is provided with a snap close that matches with hook that is fixedly mounted on the body, be hinged with a connecting rod that is provided with along the cart frame longitudinal direction between connecting lever and the interlocking baffle plate, under the drive of connecting lever, can make connecting rod drive the action of interlocking baffle plate hook look is fixed in the snap close.
After adopting above-mentioned structure, because interlocking baffle plate that the front upper place of cart frame is provided with and the pivoted arm that is hinged on the cart frame back lower place, be hinged with connecting rod between pivoted arm and the interlocking baffle plate, be provided with thus, when handcart when test position is shaken into the service position, pivoted arm action valve is opened, making simultaneously connecting rod drive the action of interlocking baffle plate under the drive of pivoted arm fixes on hook look in the snap close, the function that realization is locked a door, it is simple in structure, operation is reliable, has prevented the potential safety hazard that misoperation is opened the door and brought.
Description of drawings
Fig. 1 is the unlocked state structural representation of high-tension switch cabinet lock door mechanism of the present invention;
Fig. 2 is the lock-out state structural representation of high-tension switch cabinet lock door mechanism of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, high-tension switch cabinet lock door mechanism of the present invention is described in further detail.
As shown in the figure, high-tension switch cabinet lock door mechanism of the present invention, comprise a pivoted arm 1 that can drive valve action, the end of pivoted arm 1 is hinged on the back lower place of cart frame 2, connecting lever 1 is undertaken hinged by rotating shaft 3 and cart frame 2 and can 3 rotate around the shaft, the front upper place of cart frame 2 is hinged with an interlocking baffle plate 5, hook 6 of fixed installation on the interlocking baffle plate 5, hook the place ahead of 6 be provided with one be fixedly mounted on the body with hook 6 snap closes that match 7, snap close 7 matches with hook 6 and merges and hook can be locked, be hinged with a connecting rod 4 that is provided with along cart frame 2 longitudinal directions between connecting lever 1 and the interlocking baffle plate 5, under the drive of connecting lever 1, can make 5 actions of connecting rod 4 driving interlocking baffle plates will link up with 6 and be locked in the snap close 7.
Its operation principle is as follows:
When handcart shakes into the service position from test position, driving pivoted arm 1 clockwise rotates, open valve, the engagement of handcart dynamic/static contact, pulling connecting rod 4 moved right when pivoted arm 1 rotated, drive interlocking baffle plate 5 and hook 6 when connecting rod 4 moves and be rotated counterclockwise simultaneously, make hook 6 be locked in the snap close 7, realize locking a door function.
