The mechanism comprises a fixing frame fixedly arranged above a drawer bottom plate, a breaker operating mechanism used for enabling a breaker switch to be disconnected or closed is arranged on the fixing frame, a drawer interlocking mechanism used for enabling a drawer to be unlocked when the breaker switch is disconnected or locked when the breaker switch is closed and a driving shaft fixedly connected between the breaker operating mechanism and the drawer interlocking mechanism and used for driving the breaker operating mechanism and the drawer interlocking mechanism to act simultaneously, the driving shaft is arranged between the fixing frames in a penetrating mode, the head end of the driving shaft is exposed outside the fixing frame, the tail end of the driving shaft is fixedly connected with the breaker operating mechanism, and the drawer interlocking mechanism is fixedly connected between the head end and the tail end of the driving shaft.
However, the above-mentioned patent still has the problem, for example, a special matching operation mechanism is required to be assembled for each molded case circuit breaker model of the power distribution unit (each drawer loop) of the traditional power distribution cabinet, so that thousands of molded case circuit breakers of different models need to be matched for thousands of models of operation mechanisms due to differences in external dimensions and switching strokes, so that manufacturers for manufacturing and producing the product cannot form large-scale mass production, confusion is caused for management, product inventory overstocking is caused in a large amount, and users cannot form a large amount of waste of accessories due to various models and easy type selection errors, cost is increased due to incapability of interchanging, and the like.
Disclosure of Invention
Aiming at the problems, the invention provides the operating mechanism which has a simple structure and convenient use, adopts a mounting structure mode to subvert the traditional mode of mounting on the circuit breaker and solves the limitation that each model of the molded case circuit breaker of each manufacturer needs to be specially matched with one operating mechanism.
The technical scheme adopted by the invention for solving the problems is as follows:
an operating mechanism of a novel low-voltage molded case circuit breaker of a power distribution cabinet comprises a fixed support, wherein mounting plates are arranged on two sides of the fixed support; the shell, the shell is fixed to be set up on the fixed bolster, be equipped with the cavity in the shell, be equipped with operating device in the cavity.
Furthermore, the operating mechanism comprises a sliding rod fixed in the cavity, a sliding block is sleeved on the sliding rod, return springs are arranged at two ends of the sliding rod, a positioning block is arranged at the front end of the sliding block, and a rotating arm device is arranged on the positioning block.
The big or small design of adaptation switch that can be bigger through the design of slider, reset spring lets the switch break off with the fingers and thumb the adaptability resilience after the limit off with the fingers and thumb, gives the square shaft of giving the assignee and can adjust the position of returning to the normal position, lets the switch operation more humanized.
Furthermore, the rotating arm device comprises a shaft sleeve arranged on the shell, a rotating arm is arranged at the rear end of the shaft sleeve, a sliding groove is formed in the rotating arm, and the positioning block is movably arranged in the sliding groove.
Furthermore, the front end of the shaft sleeve is provided with a shaft hole, a tooth-shaped square hole is arranged in the shaft hole, and a square shaft is arranged on the tooth-shaped square hole.
The operating mechanism can be suitable for more switches through the design of the tooth-shaped square hole, and meanwhile, the direction of the square shaft is adjusted, so that the switch is not limited by the original square hole and the angle of the switch is not inclined.
Furthermore, the square shaft is further provided with a limiting fixing plate, the limiting fixing plate is L-shaped, one end of the limiting fixing plate is fixedly arranged on the fixing support, and the square shaft penetrates through the limiting fixing plate.
Through spacing fixed plate, the shaft of letting passes through the axle sleeve and fixes on operating device with spacing fixed plate, lets the live length of square shaft can increase greatly.
Furthermore, the rear side of the shell is also provided with a cover plate, and a hollow part is arranged on the cover plate.
The invention has the advantages that:
1. the invention has simple structure, easy processing and low cost;
2. because the technical requirements on the operating mechanism (the horizontal direction and the vertical direction when the switch is switched) are weak, the stroke of the circuit breaker produced by each manufacturer is slightly different, and the original square is changed into a multi-tooth shape by improving the design of the shaft hole, so that the problem that the connection between the connecting rod and the handle is not at a 90-degree position due to different strokes of the switches is solved;
3. in order to meet the current specification of each gear of the low-voltage molded case circuit breaker, the operating mechanism is divided into 3 types, namely, an A gear (630A-800A), a B gear (250A-400A) and a C gear (63A-125A), and thousands of types are changed into 3 types for general use. The production scale standardization is greatly improved, the user model selection confusion is relieved, and the maintenance and exchange are convenient;
4. the invention has the advantages of easy manufacture, convenient assembly, stable structure and durability.
In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided. The present invention will be described in further detail below with reference to the drawings.
