Description
Technical Field
The utility model relates to a switch board door blocking device.
Background
The power distribution cabinet needs to be kept in a locking state in the using process, so that the charged electrical components in the power distribution cabinet are prevented from damaging operating personnel, and meanwhile, external dust is prevented from entering the power distribution cabinet to the power distribution cabinet; the existing locking structure usually adopts a crank-link mechanism, wherein a link extends from the middle part of the cabinet door to the upper side and the lower side of the cabinet door; after long-term use, the end of the connecting rod is subjected to large torque, deformation is easy to occur, and the situation that the dead point of the crank connecting rod mechanism is difficult to operate and reset also occurs.
Disclosure of Invention
The utility model aims to solve the above problem, provide a switch board door blocking device specifically realizes by following technical scheme:
a locking device for a power distribution cabinet door comprises a handle part, a locking rod and a plurality of locking hooks, wherein the handle part is rotatably connected to the side edge of a cabinet door, and the locking rod is longitudinally movably arranged in the cabinet door and is positioned on the inner side of the handle part; the part of the handle part opposite to the locking rod is arc-shaped and is provided with arc teeth; the middle part of the locking rod is provided with a straight tooth opposite to the circular arc tooth, and the straight tooth is meshed with the circular arc tooth; when the handle part rotates, the circular arc teeth drive the locking rod to move upwards or downwards; the locking rod is provided with a plurality of locking holes, the locking hooks are arranged on the side part of the cabinet body, and the locking hooks correspond to the locking holes one to one; when the cabinet door is closed, the lock hook is positioned in the lock hole; when the handle part is rotated and the cabinet door is pulled, the lock hook is separated from the lock hole.
The power distribution cabinet door locking device is further designed in that a plurality of guide sleeves are vertically arranged on the inner side of the cabinet door, and the locking rod is inserted into the guide sleeves.
The power distribution cabinet door locking device is further designed in that a damping sleeve made of elastic materials is arranged inside the guide sleeve, and the locking rod penetrates through the damping sleeve.
The beneficial effects of the utility model reside in that:
the utility model utilizes the rotation of the handle part to control the longitudinal movement of the locking rod, so that the locking hook is opposite to the locking hole of the locking rod or is hooked with the edge of the locking hole, the locking or opening state of the cabinet door is realized, the arrangement positions of the locking hook and the locking hole can be selected optionally, and the torque born by the locking hook and the locking rod can be controlled in a lower range; the dead point problem of the crank connecting rod mechanism can not occur; make the dead weight of locking lever directly transmit to the cabinet door on through setting up the damping cover, can not transmit to handle portion for locking or open mode remain stable.

Fig. 2 is a schematic structural view of an end face of a guide sleeve.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
a locking device for a power distribution cabinet door comprises a handle part 1, a locking rod 2 and a plurality of locking hooks 3, wherein the handle part is rotatably connected to the side edge of a cabinet door 4, and the locking rod is longitudinally movably arranged in the cabinet door and is positioned on the inner side of the handle part; the part of the handle part opposite to the locking rod is arc-shaped and is provided with arc teeth; the middle part of the locking rod is provided with a straight tooth opposite to the circular arc tooth, and the straight tooth is meshed with the circular arc tooth; when the handle part rotates, the circular arc teeth drive the locking rod to move upwards or downwards; the locking rod is provided with a plurality of locking holes 5, the locking hooks are arranged on the side part of the cabinet body 8, and the locking hooks correspond to the locking holes one by one; when the cabinet door is closed, the lock hook is positioned in the lock hole; when the handle part is rotated and the cabinet door is pulled, the lock hook is separated from the lock hole.
The utility model utilizes the rotation of the handle part to control the longitudinal movement of the locking rod, so that the locking hook is opposite to the locking hole of the locking rod or is hooked with the edge of the locking hole, the locking or opening state of the cabinet door is realized, the arrangement positions of the locking hook and the locking hole can be selected optionally, and the torque born by the locking hook and the locking rod can be controlled in a lower range;
the inner side of the cabinet door is vertically provided with a plurality of guide sleeves 6, and the locking rod is inserted in the guide sleeves. And a damping sleeve 7 made of elastic material is arranged in the guide sleeve, and the locking rod penetrates through the damping sleeve. The dead point problem of the crank connecting rod mechanism can not occur; make the dead weight of locking lever directly transmit to the cabinet door on through setting up the damping cover, can not transmit to handle portion for locking or open mode remain stable.
