Abstract

The utility model discloses a door locking mechanism for a high-voltage switch cabinet. The mechanism includes a connecting lever capable of driving a movable door to move; the tail end of the connecting lever is hinged at the rear lower part of a trolley frame; an interlocking baffle is hinged at the upper front part of the trolley frame; a hook is fixed on the interlocking baffle; a lock catch, which is installed on the door body and is in cooperation with the hook, is arranged in front of the hook; a connection rod which is arranged along the longitudinal direction of the trolley frame is hinged between the connecting lever and the interlocking baffle; and under the drive of the connecting lever, the connection rod drives the interlocking baffle to move so that the hook is locked in the lock catch. Through adoption of the above-mentioned structure, when the trolley is switched from a test position to a work position, the connecting lever drives the movable door to open and at the same time, under the drive of the connecting lever, the connection rod drives the interlocking baffle to move so that the hook is locked in the lock catch and thus door locking function is realized. The door locking mechanism is simple in structure, reliable in operation and capable of preventing potential safety hazard resulted from error operation.

Description

The high-tension switch cabinet lock door mechanism
Technical field
The utility model 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, and when handcart shook into the service position from test 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 problems to be solved in the utility model 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 utility model, 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 arranges 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 the interlocking baffle plate that the front upper place of cart frame arranges 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, arrange thus, when handcart shook into the service position from test position, pivoted arm action valve was 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 the utility model high-tension switch cabinet lock door mechanism;
Fig. 2 is the lock-out state structural representation of the utility model high-tension switch cabinet lock door mechanism.
Embodiment
Below in conjunction with the drawings and specific embodiments, high-tension switch cabinet lock door mechanism of the present utility model is described in further detail.
As shown in the figure, high-tension switch cabinet lock door mechanism of the present utility model, 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 arranges 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.
