Abstract
The utility model relates to a door opening power-off device for electrical boxes, composed of an actuating mechanism, a transmission mechanism and a locking mechanism. The utility model is characterized in that the transmission mechanism and the actuating mechanism are transmitted by a flexible shaft. The actuating mechanism which is composed of a bracket, a supporting board, a transmission plate, an unlocking plate, a shaft pin, a ferrule, a hollow rivet and a spring is installed on the unlocking mechanism of a power switch. The flexible shaft penetrates into the small holes on the upper ends of the bracket and the transmission plate and is locked by a check ring, so the flexible shaft can move to and fro to contact the unlocking mechanism of the power switch. A sleeve barrel whose inner part is provided with a push rod, another spring and another flexible shaft can be installed on door frame of an electrical box. When the door of the electrical box is opened, the push rod pops up under the action of the spring, and the flexible shaft transmits the actuating mechanism and contacts the unlocking mechanism.
Description
The utility model relates to a kind of electric box that is used for and opens the linkage that chamber door is cut off the electricity supply.
For safety utilization of electric power, the mains switch in the electric box must be carried out mechanical interlocking with the chamber door of electric box, promptly one opens the electric box door, and mains switch must trip immediately, cuts off the electricity supply, and is called for short door opening electrical outage.The DZ series automatic switch of traditional mode of production is installed in when making mains switch in the electric box, and link-type door opening electrical outage device is housed.This apparatus parts is many, complex structure; Troublesome poeration must be pulled the handle of door opening electrical outage device earlier when opening electric chamber door, make the switch outage, rotate the electric box door locking handle again door opened, if operation sequence anti-damage device and switch easily; The linkage action is insensitive, because operating physical force acts on the handle of switch, action required power is big.
The purpose of this utility model provides electric box door opening electrical outage device a kind of simple in structure, easy to operate.
The door opening electrical outage device that the utility model proposes is by actuator, transmission mechanism and latching device are formed, it is characterized in that adopting between transmission mechanism and the actuator flexible axle transmission, actuator is by support, supporting plate, driver plate, the dropout plate, pivot pin, lasso, tubular rivet and spring constitute, actuator is installed on the tripping mechanism of mains switch, support, other plate and supporting plate are fixed into one with tubular rivet, the support upper end is provided with through hole can allow the axle core of flexible axle pass, the axle core passes driver plate upper end aperture simultaneously and locks with back-up ring, driver plate is supported on the pivot pin that is installed between supporting plate and the other plate by lasso, and can swing around pivot pin, the driver plate lower end is fastening with tubular rivet and dropout plate, between the supporting plate on dropout plate and the support spring is housed, the dropout plate can back and forth touch the tripping mechanism of mains switch under the effect respectively of driver plate and spring.Sleeve in the transmission mechanism is a hollow cylinder, the push rod that the middle part is provided with groove is housed in the front end endoporus, collar and fastening with screw is housed in the endoporus of rear end, insert flexible axle in the collar, between flexible axle end and the push rod spring is housed, the barrel forward end lateral surface is installed the latching device of being made up of fore-set, nut, spring and cover plate, and the sleeve rear end lateral surface is provided with screw thread and equipped 2 clamp nuts.Sleeve is placed on the electric box doorframe, fix and the push rod of sleeve is contacted with electric chamber door by clamp nut, when chamber door is shut, door compressing push rod, push rod discharges actuator by flexible axle, the switch energising of can closing, when chamber door was opened, push rod ejected under the effect of spring, driver plate in the flexible axle transmission actuator and dropout plate, the dropout plate touches the tripping mechanism in the mains switch, and mains switch is disconnected, and realizes the door opening electrical outage function.
The electric box door opening electrical outage apparatus structure that the utility model proposes is simple, easy to operate, and opening electric chamber door need not other action, and switch is that automatic trip disconnects; Also convenient by dress, owing to adopted the flexible axle connection, switch can be installed in the optional position, no specific (special) requirements; The employing flexible axle flexibly connects, and action required power is little, and has improved reliability.
Followingly concrete enforcement of the present utility model is further described with reference to accompanying drawing.It shown in the accompanying drawing structure chart of door opening electrical outage device, its structure comprises actuator, transmission mechanism and latching device, it is characterized in that adopting between transmission mechanism and the actuator flexible axle (11) transmission, actuator is by support (14), supporting plate (13), driver plate (15), dropout plate (22), pivot pin (18), lasso (19), tubular rivet (17) (20) and spring (21) constitute, actuator is installed on the tripping mechanism of mains switch, support (14), other plate (12), supporting plate (13) is fixed into one with tubular rivet (17), support (14) upper end is provided with through hole can allow the axle core of flexible axle (11) pass, and the axle core passes driver plate (15) upper end aperture simultaneously also with back-up ring (16) locking.Flexible axle (11) adopts the shutter flexible shaft line of camera, and the cable release of camera has been approved product at home, and its structure is light and handy, and operating physical force is little, and dependable performance, and the length of flexible axle (11) can be decided according to user's actual needs.Driver plate (15) is supported on the pivot pin (18) that is installed between supporting plate (13) and the other plate (12) by lasso (19), and can swing around pivot pin (18), driver plate (15) lower end is fastening with tubular rivet (20) and dropout plate (22), between the supporting plate (13) on dropout plate (22) and the support (14) spring (21) is housed, dropout plate (22) can back and forth promote the tripping mechanism of mains switch under the effect respectively of driver plate (15) and spring (21).Sleeve in the transmission mechanism (6) is a hollow cylinder, collar (10) and fastening with screw (9) is housed in the front end endoporus, insert flexible axle (11) in the collar (10), between flexible axle (11) end and the push rod (1) spring (7) is housed, sleeve (6) rear end lateral surface is provided with screw thread and is furnished with 2 clamp nuts (8), sleeve (6) front end lateral surface is installed by fore-set (2), nut (5), the latching device that spring (4) and cover plate (3) are formed, nut (5) is fixed in the circular hole of sleeve (6) side, fore-set (2) and spring (4) are housed in the middle of the nut (5), and the top is pushed down with cover plate (3).When electric box needs repairing, can when opening, chamber door close a switch by locker, this moment, the fore-set (2) of locker was inserted in the intermediate groove of push rod in the transmission mechanism (1), push rod (1) can't be moved, be that the door opening electrical outage device is locked ineffective, locker can discharge automatically when chamber door is shut again, and when chamber door was opened again, switch promptly tripped and still carries out the door opening electrical outage action.
