Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and specifically, to a power distribution cabinet door. Background Art

[0002] In the design of existing power distribution cabinets, the opening and closing of the door panel usually rely on simple mechanical structures such as hinges and latches.

[0003] The existing simple distribution cabinet door is only limited by a single bolt. The force is concentrated, and the door panel or the bolt is prone to deformation during use. The locking effect of a single position is average, and the safety is average.

[0004] In summary, if a latch system that can provide multi-stage locking and unlocking and simultaneously control the opening and closing around the entire door panel can be provided, it will achieve better use. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a power distribution cabinet door to facilitate the opening and closing of the distribution cabinet door.

[0006] The utility model adopts the following technical solutions to achieve the invention purpose:

[0007] A power distribution cabinet door, including a door panel, is characterized in that:

[0008] Card slots are respectively and fixedly connected to both sides of the door panel. A card block can be inserted into each of the card slots, and the card block can pass through the card slot and be inserted into a limit snap ring fixed to the distribution cabinet body;

[0009] One ends of two opposite card blocks are respectively and fixedly connected to one end of a connecting rod. The other end of the connecting rod is hinged to one end of a short rod. The other end of the short rod is hinged to one end of a crank arm. The center of the crank arm is hinged to the door panel. The other ends of the crank arms are respectively hinged to one ends of swing rods. The other ends of the two swing rods are respectively hinged to both ends of a moving block. The moving block is fixedly connected to a square plate. The square plate is fixedly connected to one end of a cross bar. The cross bar is fixedly connected to a rack. The rack meshes with a gear. The central axis of the gear is rotationally connected to the door panel.

[0010] As a further limitation of this technical solution, a handle is fixedly connected to the end of the central axis of the gear.

[0011] As a further limitation of this technical solution, a limit slide rail is also fixedly connected to one side of the middle part of the door panel. A limit block is matched in the limit slide rail. Both sides of one end of the limit block are respectively fixedly connected to side bars. The outer sides of the two side bars are respectively attached to the inner side of the limit slide rail. One end of a side bar is fixedly connected to a square block, and the square block fixes the rack.

[0012] As a further limitation of the technical solution, the other end of the limiting block can be inserted into the limiting card slot fixed on the power distribution cabinet.

[0013] As a further limitation of the technical solution, both the card slot and the limiting slide rail are made of stainless steel.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0015] Rotating the handle can drive the gear to rotate. The gear can move the limiting block along the direction of disengaging from the limiting slide rail through the movement of the rack, the square block, the side strip and the limiting block, and then disengage from the limiting card slot fixed on the power distribution cabinet body;

[0016] The rack can also drive the cross bar to move. Through the movement of the cross bar, the square plate, the moving block and the swing rod, the crank arm swings. The crank arm drives the short rod to swing, the short rod drives the connecting rod to move, and the connecting rod drives the clamping block to move along the direction of disengaging from the card slot, and then disengage from the limiting snap ring fixed on the power distribution cabinet body, realizing the release of the power distribution cabinet body and the door panel;

[0017] Rotating the handle in the reverse direction enables the clamping block to be inserted into the limiting snap ring and the limiting block to be inserted into the limiting card slot, realizing the locking of the door panel and the power distribution cabinet body. Through a series of hinge and meshing mechanisms, the door panel of the device can achieve multi-stage locking and unlocking during the opening and closing processes, thereby improving the operation safety;

[0018] By rotating a single handle, the opening and closing of the entire door panel can be controlled, simplifying the operation process. The card slot and the limiting slide rail made of stainless steel enhance the corrosion resistance and wear resistance of the components and extend the service life of the product.

The square plate 16 is fixedly connected to one end of a cross bar 13. The cross bar 13 is fixedly connected to a rack 12. The rack 12 meshes with a gear 9. The central axis of the gear 9 is rotationally connected to the door panel 1.

[0030] The end of the central axis of the gear 9 is fixedly connected to a handle 7.

[0031] One side of the middle part of the door panel 1 is also fixedly connected with a limit slide rail 5. A limit block 6 is matched in the limit slide rail 5. On both sides of one end of the limit block 6, side strips 10 are respectively fixedly connected. The outer sides of the two side strips 10 are respectively attached to the inner side of the limit slide rail 5. One end of one side strip 10 is fixedly connected with a square block 11, and the square block 11 fixes the rack 12.

[0033] Both the card slot 2 and the limit slide rail 5 are made of stainless steel.

[0034] During use, rotating the handle 7 can drive the gear 9 to rotate. The gear 9 can drive the rack 12 to move. The rack 12 drives the square block 11, the side strip 10 and the limit block 6 to move. The limit block 6 moves along the direction of separating from the limit slide rail 5, and then separates from the limit card slot fixed on the power distribution cabinet body. At the same time, the rack 12 also drives the cross bar 13 to move. The cross bar 13 drives the square plate 16 and the moving block 14 to move. The moving block 14 drives the swing rod 15 to swing. The swing rod 15 drives the crank arm 8 to swing. The crank arm 8 drives the short rod 4 to swing. The short rod 4 drives the connecting rod 3 to move. The connecting rod 3 drives the clamping block 31 to move along the direction of separating from the card slot 2, and then separates from the limit snap ring fixed on the power distribution cabinet body, realizing the release of the power distribution cabinet body and the door panel 1. Rotating the handle in the reverse direction enables the clamping block 31 to be inserted into the limit snap ring and the limit block 6 to be inserted into the limit card slot, realizing the locking of the door panel 1 and the power distribution cabinet body 1.
