Embodiment Construction
[0032] As shown in the figure, the present invention is a simple integrated low-voltage switchgear drawer interlocking mechanism, such as Figure 11-13 As shown, the main cabinet 13 is an MNS cabinet with a conventional C profile structure. The main component inside each drawer unit 12 is a molded case circuit breaker 1 switch. The vertical row 14 is wired from the horizontal busbar to provide the main incoming line power to the plastic case inside the drawer. Plug-in 15, when the drawer is pushed to the working position, the first-time incoming line plug-in is engaged with the vertical row, and the first-time outgoing line plug-in is dynamically and statically engaged to realize the function of the molded case outgoing line transfer cabinet. The drawer layer partition 17 is installed with the main cabinet body, the main load-bearing parts and interlocking parts of the drawer. Guide rail 16, the drawer bearing 21 and the guide rail limit post 22 on both sides of the drawer u...

The invention relates to a simple integrated low-voltage switch cabinet drawer interlocking mechanism. An interlocking rod pin shaft, an interlocking rod pin shaft positioning piece, a square shaft, a square shaft linkage rod, a crank, a handle clamping piece, a handle clamping piece and the like are arranged in each drawer unit, one end of the square shaft is connected with a handle, the other end of the square shaft is connected with the square shaft linkage rod, the square shaft linkage rod is connected with the crank, and the crank is connected with the handle clamping piece; when the handle is rotated, the square shaft rotates to drive the square shaft linkage rod to horizontally move, so that the crank is driven to horizontally move, the handle clamping piece horizontally moves in the clamping groove of the fixing plate under the action of the crank, and the handle clamping piece controls the opening and closing operation of the molded case circuit breaker. The drawer interlocking mechanism is suitable for manual operation drawer interlocking in a power distribution scheme of the low-voltage switch cabinet, the installation precision and convenience are improved, the problems of deflection and clamping stagnation of the drawer due to uneven stress are solved, the safety, convenience, flexibility and reliability of the low-voltage switch cabinet are improved, and the drawer interlocking mechanism is simple in structure, convenient to install, high in efficiency, low in cost and convenient to apply and popularize.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a simple integrated low-voltage switch cabinet drawer interlocking mechanism. Background technique [0002] Most of the low-voltage drawer mechanisms are now composed of three parts, which are the operating mechanism that controls the opening and closing of the plastic case, the push mechanism that controls the entry and exit of the drawer, and the interlock mechanism for safety control. The general operating mechanism is a separate manufacturer, and the propulsion mechanism and interlocking mechanism are from another manufacturer. When the three mechanisms are used together, the problem of insufficient opening and closing travel of the molded case circuit breaker often occurs. The complex structure of the split mechanism will increase the difficulty of interlocking and assembly. In addition, some drawer push mechanisms now mostly use a swing-in mechanism. During th...
