Abstract
The utility model provides a valve self-locking mechanism of a centrally-mounted switch cabinet, which comprises a fixed plate, a bent plate, an upper connection plate, a lower connection plate and a locking device, wherein the upper connection plate and the lower connection plate are respectively hinged at the front end of the fixed plate; the locking device is fixedly arranged at the back end of the fixed board; and the bent plate locks the upper connection plate via the locking device. The valve self-locking mechanism of the centrally-mounted switch cabinet is characterized in that the locking device comprises a bending plate and a sidesway plate, wherein the bending plate is fixed on the fixed plate; the bent plate is hinged on the bending plate; a sliding groove is arranged on the bending side wall of the bending plate; the sidesway plate is mounted inside the sliding groove and can move horizontally; a plane exists where the upper connection plate and the fixed plate are hinged; a locking groove is arranged on the plane; and the locking groove is engaged with the sidesway plate extending out from the sliding groove of the bending plate. The self-locking mechanism is simple in structure and has the self-locking function; when a handcart is drawn out of the cabinet body, a maintainer can lock the valve plate during the maintenance process for blocking a contact box and a static contact, thereby avoiding electric shock injury caused by mis-operation.
Description
Technical field
The utility model relates to a kind of electric device, relates in particular to a kind of valve self-locking mechanism of mid-switch cubicle.
Background technology
Mid-switch cubicle circuit breaker be installed on the handcart, fixed contact is installed in the switch cubicle and is connected with high-tension line, utilize the propelling of circuit breaker cart or pull out realize moving contact and fixed contact be connected or disconnection connection and the disconnection of realization circuit.Because fixed contact often is live end, jeopardize personal safety in order to prevent the maintenance personal from when overhauling circuit, launching an attack fixed contact because of carelessness, the valve up and down that links with circuit breaker cart is set in the fixed contact dead ahead is used for blocking charged fixed contact, carry out security protection; Valve is by the interlock of transmission mechanism and handcart up and down, when handcart advances up and down valve open, when handcart is pulled out up and down valve close.When valve is closed up and down, in order to prevent misoperation it is opened, generally be provided with valve self-locking device up and down.But switch cubicle valve self-locking mechanism complex structure of the prior art, the cost height, different circuit breakers can not be general, and switch cubicle need increase installing hole, and it is big to take up room, and structure is not compact.
The utility model content
In order to solve the above problem that exists in the background technology, the utility model provides a kind of valve self-locking mechanism of mid-switch cubicle, this self-locking mechanism is simple in structure, has auto-lock function, after handcart was drawn out of cabinet, the maintainer can pin valve plate when maintenance, block contact box and fixed contact, the electric shock injury of having avoided misoperation to bring.
For achieving the above object, the utility model adopts following technical scheme:
A kind of valve self-locking mechanism of mid-switch cubicle, comprise fixed head, bent plate, upper plate, lower plate and locking device, win in succession on described and descend to win in succession and be hinged on the front end of fixed head respectively, described locking device is fixedly mounted on the rear end of fixed head, described bent plate is by winning in succession in the locking device locking, it is characterized in that, described locking device comprises bent plate and sidesway plate, described bent plate is fixed on the fixed head, bent plate is hinged on the bent plate, has sliding tray on the crooked sidewall of bent plate, described sidesway plate is installed in the sliding tray and can move left and right, on win in succession and have a plane with the hinged place of fixed head, have lock slots on the plane, lock slots and the sidesway plate engagement of stretching out from the bent plate sliding tray.
Be provided with extension spring between the bottom of described bent plate and the fixed head.
The beneficial effects of the utility model are:
1, simple in structure, have auto-lock function.
2, do not take up room;
3, the easily maintenance of back of breaking down.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the structural representation of the utility model embodiment 1;
Wherein: fixed head 1, upper plate 2, lower plate 3, bent plate 4, bent plate 5, sidesway plate 6.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further described:
Embodiment 1
As shown in Figure 1, a kind of valve self-locking mechanism of mid-switch cubicle, comprise fixed head 1, bent plate 4, upper plate 2, lower plate 3 and locking device, win 2 and 3 front ends that are hinged on fixed head 1 respectively of winning in succession down on described in succession, described locking device is fixedly mounted on the rear end of fixed head 1, described bent plate 4 is by winning 2 in succession in the locking device locking, described locking device comprises bent plate 5 and sidesway plate 6, described bent plate 5 is fixed on the fixed head 1, bent plate 4 is hinged on the rear wall of bent plate 5, the crooked sidewall of bent plate 5 is provided with two open slots, these two open slots are sliding tray, and described sidesway plate 6 is installed in the sliding tray and can move left and right, on win in succession and 2 have a plane with the hinged place of fixed head 1, has lock slots on the plane, lock slots and sidesway plate 6 engagements of stretching out from the bent plate sliding tray.
Be provided with extension spring between the bottom of described bent plate 4 and the fixed head 1.
During work, on win in succession with under win in succession respectively and to link to each other with valve up and down by transmission mechanism, on the rotation of winning in succession or winning in succession down can make up and down valve open or close.When pulling out handcart, bent plate 4 is rotated counterclockwise around axle under the effect of extension spring, drives sidesway plate 6 and slides to the right, and described sidesway plate stretches in the lock slots on the plane of winning in succession, and making wins in succession can not rotate, this moment of valve locking up and down.After advancing handcart, bent plate 4 turns clockwise around axle under the effect of handcart push pedal, drives sidesway plate 6 and slides left, and sidesway plate 6 skids off from lock slots, and it is free to rotate to win in succession on this moment, and latch-release can operate as normal.
It will be recognized by those skilled in the art, under the prerequisite that does not depart from protection scope of the present invention, can carry out various modifications, variation and combination to above-mentioned execution mode, and think that this modification, variation and combination are within the scope of originality thought.
