Abstract
The utility model discloses a switch cabinet front door automatic locking and unlocking mechanism. The switch cabinet front door automatic locking and unlocking mechanism comprises a locking installing plate and a locking plate installed on a lower door plate. A locking plate, a locking shaft, a revolving shaft and a shaft pin are fixedly arranged on the locking installing plate. The locking plate is connected with the locking installing plate through the revolving shaft in a movable mode. The shaft pin is fixedly arranged on the locking installing plate through a long groove hole in the locking plate. The locking shaft is fixedly connected with a locking head area of the locking plate. A wheel rail is arranged on the bottom of the locking plate. The switch cabinet front door automatic locking and unlocking mechanism is simple in structure and convenient to use. When a handcart in the switch cabinet moves between the test position and the operation position, the automatic locking or unlocking of a lower door of the switch cabinet is achieved by the fact that the mechanism is positioned and driven by using a disconnector handcart. The switch cabinet front door automatic locking and unlocking mechanism is simple and convenient to operate and high in reliability.
Description
Technical field
The utility model relates to a kind of Lock for switch cabinet, specifically relates to a kind of front door of switch cabinet automatic blocking unlocking mechanism.
Background technology
Front door of switch cabinet locking is both at home and abroad at present adopted electric blocking more or with the locking of earthing switch operation macro-axis, is needed component more with the locking of ground connection macro-axis, and complex structure is prone to stuck, malfunction phenomenon.And incoming line switch cabinet and PT cabinet generally do not have earthing switch, and the Xiamen locking can only be used electric blocking, but the shortcoming of electric blocking is maloperation easily to occur, and reliability is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and shortcoming, a kind of switchboard simple in structure, easy to use Xiamen automatic locking mechanism is provided, when handcart in switchboard moves between testing position and operating position, utilize this winding machine switchboard of circuit breaker cart Locating driver Xiamen by automatic blocking or release, easy and simple to handle, reliability is high.
For reaching above-mentioned technique effect, the utility model adopts following technical scheme: a kind of front door of switch cabinet automatic blocking unlocking mechanism comprises locking installing plate and the jam plate that is arranged on lower door-plate, be fixed with latch plate, latch shaft, rotating shaft and pivot pin on the locking installing plate, locking version and locking installing plate are flexibly connected by rotating shaft, pivot pin is fixedly installed on the locking installing plate by the long slot bore on latch plate, the tapered end district of latch shaft and latch plate is fixedly connected with, and the latch plate bottom is provided with wheel track.
Preferably, described wheel track comprises horizontal segment and the arc section of connection, and the convex globoidal of arc section is downward.
Preferably, described jam plate is L-type, and jam plate is provided with locked groove.
The beneficial effects of the utility model:
Switchboard simple in structure, easy to use of the present utility model Xiamen automatic locking mechanism, when handcart in switchboard moves between testing position and operating position, utilize this winding machine switchboard of circuit breaker cart Locating driver Xiamen by automatic blocking or release, easy and simple to handle, reliability is high.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the front view that the utility model is installed;
Fig. 3 is the structural representation of the utility model jam plate.
Wherein: 1-rotating shaft, 2-locking installing plate, 3-latch plate, 4-pivot pin, 5-latch shaft, 6-jam plate, 7-wheel track.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of front door of switch cabinet automatic blocking unlocking mechanism, comprise locking installing plate 2 and the jam plate 6 that is arranged on lower door-plate, locking installing plate 2 is provided with latch plate 3, latch shaft 5, rotating shaft 1 and pivot pin 4, latch plate 3 and locking installing plate 2 are flexibly connected by rotating shaft 1, pivot pin 4 is fixedly installed on locking installing plate 2 by the long slot bore on latch plate 3, the tapered end district of latch shaft 5 and latch plate 3 is fixedly connected with, latch plate 3 bottoms are provided with wheel track 7, wheel track 7 comprises horizontal segment and the arc section of connection, and the convex globoidal of arc section is downward; Jam plate 6 is L-type, and jam plate 6 is provided with locked groove.
During use, locking installing plate 2 is installed on switch cabinet handcart chamber right side wall, and the long slot bore on latch plate 3 can move up and down along pivot pin 4, latch shaft 5 is inserted or deviate from locked groove in jam plate 6, reaches the purpose of switchboard Xiamen automatic blocking and release.
Circuit breaker cart moves to the process of operating position from testing position, the locating wheel of handcart side is advanced in the other direction along X, slide on the wheel track 7 of latch plate 3, thereby promoting latch plate 3 rotates counterclockwise centered by rotating shaft 1, latch plate 3 drives latch shaft 5 and synchronously rotates, and latch shaft 5 moves to Y-direction, when latch shaft 5 is elevated to a certain position, latch shaft 5 is inserted in the locked groove of jam plates 6, and the switchboard Xiamen is by automatic blocking.
Circuit breaker cart is during from the operating position to testing position, the handcart locating wheel is advanced along directions X, track 7 along latch plate 3 slides, and latch plate 3 borrows self gravitation to descend, and is pasting locating wheel and is descending, latch plate 3 clockwise rotates centered by rotating shaft 1, latch plate 3 drives latch shaft 5 and synchronously rotates, and latch shaft 5 moves in the other direction to Y, when latch shaft 5 drops to a certain position, latch shaft 5 is deviate from from the locked groove of jam plate 6, and the switchboard Xiamen is by automatic unlocking.
Switchboard simple in structure, easy to use of the present utility model Xiamen automatic locking mechanism, when handcart in switchboard moves between testing position and operating position, utilize this winding machine switchboard of circuit breaker cart Locating driver Xiamen by automatic blocking or release, easy and simple to handle, reliability is high.
Above-described is only preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, as the common practise of this area, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model.
