The blocking at moment is kept in use, in case other people maloperations cause unnecessary personal injury.But conventional opens
Closing cabinet only has front cabinet door to have perfect blocking function, and two rear cabinet doors are then separately fixed at out by bolted connection
It closes on cabinet, does not have blocking function.And traditional lock is also difficult on the basis of not destroying switchgear original structure directly
It is used on the rear cabinet door of switchgear.Therefore, it is necessary to a kind of buckle structures that can be directly used for switchgear rear cabinet door.
Summary of the invention
The object of the present invention is to provide a kind of switchgear after-frame door buckle structures.It can be directly installed on switch
On cabinet rear cabinet door, and have structure simple, the good feature of latch effect.
Technical solution of the present invention: a kind of switchgear after-frame door buckle structure, including being separately fixed on after-frame door
Upper bed-plate and lower bottom base, are connected with the first bolt between upper bed-plate and lower bottom base, lower bottom base is equipped with the second bolt, the second bolt
Upper end is located above lower bottom base, and the second bolt lower end extends to below lower bottom base and is connected with lock body, the upper bed-plate and bottom
It is equipped with and bolted fixation hole on seat.
A kind of switchgear after-frame door buckle structure above-mentioned, first bolt be located at upper bed-plate on the outside of fixation hole and
On lower bottom base.
A kind of switchgear after-frame door buckle structure above-mentioned, the lower bottom base are equipped with lockhole, and lockhole side is equipped with limit
Position step, first bolt lower end extend to below limited step, and second bolt passes through lockhole and connects lock body.
A kind of switchgear after-frame door buckle structure above-mentioned, first catch top, which is equipped with, to be located above upper bed-plate
Baffle, the first bolt middle part are equipped with strip hole.
A kind of switchgear after-frame door buckle structure above-mentioned, second bolt side are equipped with fixture block, fixture block setting length
In hole, the bottom of fixture block bottom and strip hole is bonded to each other.
A kind of switchgear after-frame door buckle structure above-mentioned, the shape of second bolt are L shape, the second catch top
Equipped with the folded plate being located above lower bottom base.
Compared with prior art, upper bed-plate and lower bottom base are connect with two after-frame doors of switchgear by the present invention respectively, and
Make to be connected with each other between upper bed-plate and lower bottom base by the first bolt, by buckleing the fixture block of the second bolt after the placement of the first bolt
Enter in strip hole, and it can be limited by the cooperation of the second bolt and lockhole, inserts the first bolt in the second bolt
It is in locking state after entering, prevents moving up and down for the first bolt；And the first bolt then can be to upper bed-plate under after locked
Fixation hole on pedestal is stopped, and is prevented other people from extracting the first bolt out in the state that the second bolt is locked and is unscrewed fixation hole
The bolt at place, structure is simple, and latch effect is good；By the cooperation of fixation hole and the first bolt, it is used in the spiral shell of connection after-frame door
Bolt can be fixed directly through upper bed-plate and lower bottom base, so that the present invention be allow to be directly installed on existing switchgear after-frame
Men Shang reduces the installation difficulty of user and improves the applicability of itself.In addition, the present invention by each External Shape into
One step limits, and can make each part that can use plate machine-shaping, reduce production cost and difficulty of processing of the invention.Institute
With the present invention can be directly installed on switchgear rear cabinet door, and have structure simple, the good feature of latch effect.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the top view of lower bottom base.
The label in accompanying drawing is: 1- upper bed-plate, 2- lower bottom base, the first bolt of 3-, the second bolt of 4-, 5- lock body, 6- are fixed
Hole, 201- lockhole, 202- limited step, 301- baffle, 302- strip hole, 401- fixture block, 402- folded plate.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of switchgear after-frame door buckle structure is constituted as shown in Figure 1, including being separately fixed at after-frame door
On upper bed-plate 1 and lower bottom base 2, be connected with the first bolt 3 between upper bed-plate 1 and lower bottom base 2, lower bottom base 2 is equipped with second and inserts
Pin 4,4 upper end of the second bolt are located at 2 top of lower bottom base, and 4 lower end of the second bolt extends to 2 lower section of lower bottom base and is connected with lock body 5,
Be equipped on the upper bed-plate 1 and lower bottom base 2 with bolted fixation hole 6, bolt is after passing through upper bed-plate 1 or lower bottom base 2
It is sequentially connected after-frame door and switch cabinet.
First bolt 3 is vertically arranged on the upper bed-plate 1 and lower bottom base 2 in 6 outside of fixation hole.
The lower bottom base 2 is equipped with lockhole 201, and 201 side of lockhole is equipped with limited step 202,3 lower end of the first bolt
202 lower section of limited step is extended to, second bolt 4 passes through lockhole 201 and connects lock body 5；Mechanical code lock can be selected in lock body 5
Or padlock.
It is equipped with the baffle 301 for being located at 1 top of upper bed-plate at the top of first bolt 3, is equipped with strip hole in the middle part of the first bolt 3
302。
Second bolt, 4 side is equipped with fixture block 401, and fixture block 401 is arranged in strip hole 302,401 bottom of fixture block and strip
