Abstract
Description
Technical Field
[0001] The utility model relates to a drawer seat of a frame type circuit breaker, in particular to a door plate linkage mechanism of the drawer seat of the frame type circuit breaker. Background Art
[0002] Frame circuit breakers, also known as universal circuit breakers, are mechanical switchgear that can connect, carry and disconnect current under normal circuit conditions, and can also connect, carry for a certain time and disconnect current under specified abnormal circuit conditions. It is mainly used to distribute electrical energy and protect lines and power equipment from overload, undervoltage, short circuit and other faults. Frame circuit breakers are usually installed in switch cabinets through drawer seats, which have interlocking devices to ensure safety during equipment operation and maintenance.
[0003] At present, a door panel linkage mechanism is used in the drawer seat of the frame type circuit breaker to control the movement of the insulating door panel when the frame type circuit breaker enters and exits the drawer seat, so as to ensure that the busbar is blocked by the insulating door panel when it is not connected. However, the existing pull plate mechanism has a complex structure, does not move smoothly, and is easy to get stuck. Summary of the invention
[0004] In view of the above-mentioned deficiencies, the utility model provides a pull plate mechanism for a frame type circuit breaker drawer seat which has a simple structure and is easy to operate.
[0005] In order to achieve the above purpose, the utility model adopts a door panel linkage mechanism of a frame-type circuit breaker drawer seat, including side panels on both sides, a main shaft, a fan-shaped large gear, a transmission gear, a connecting rod, a door panel bracket, and an insulating door panel. The fan-shaped large gear is connected to both ends of the main shaft, the transmission gear is hinged on the side panel above the fan-shaped large gear, the transmission gear is linked to the door panel bracket through a connecting rod, the insulating door panel is connected to the door panel bracket, a connecting rod groove is formed at the center of the connecting rod, the connecting rod is connected to the side panel through the connecting rod groove and slides, the lower end of the connecting rod is connected to the top of the transmission gear, the door panel bracket is hinged to the side panel above the connecting rod, the top of the connecting rod is connected to the door panel bracket, and a torsion spring for rotating the door panel bracket downward is provided on the door panel bracket.
[0006] The utility model is further configured such that the lower end of the connecting rod is pressed against the outer edge end of the transmission gear, and the upper end of the connecting rod is hinged on the door panel bracket. The connection between the connecting rod and the transmission gear is reliable and easy to assemble.
[0007] The beneficial effect of the utility model is that the insulating door panel is controlled in linkage by using a connecting rod and a door panel bracket, the connecting rod is directly linked with the transmission gear, and the linkage is direct and reliable; the connection between the connecting rod and the transmission gear is non-fixed, and no connection assembly is required, making the production and assembly of the drawer seat more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1It is a schematic diagram of a specific embodiment of the utility model with one side panel removed.
[0009] Figure 2 It is a side view of a specific embodiment of the utility model with one side panel removed. DETAILED DESCRIPTION
[0010] like Figure 1 , Figure 2 As shown, the specific embodiment of the utility model is a door panel linkage mechanism of a frame-type circuit breaker drawer seat, including side panels 1 on both sides, a main shaft 2, a fan-shaped large gear 3, a transmission gear 4, a connecting rod 5, a door panel bracket 6, and an insulating door panel 7. The fan-shaped large gear 3 is connected to both ends of the main shaft 2, and the transmission gear 4 is hinged on the side panel above the fan-shaped large gear 3 and meshes with the fan-shaped large gear 3. The transmission gear 4 is linked to the door panel bracket 6 through the connecting rod 5, and the insulating door panel 7 is connected to the top of the door panel bracket 6 and moves with the door panel bracket The frame 6 moves up and down with the rotation, a connecting rod groove 51 is formed in the center of the connecting rod 5, a connecting rod shaft 11 is arranged on the side panel 1, the connecting rod groove 51 is passed through the connecting rod shaft 11 on the side panel 1, and the connecting rod 5 slides on the connecting rod shaft 11 through the cooperation between the connecting rod groove 51 and the connecting rod shaft 11. The lower end of the connecting rod 5 is pressed against the outer end of the upper edge of the transmission gear 4, the door panel bracket 6 is hinged on the side panel 1 above the connecting rod 5, the upper end of the connecting rod 5 is hinged on the door panel bracket 6, and the door panel bracket 6 is provided with a torsion spring 8 for rotating the door panel bracket 6 downward.
