Abstract
The utility model relates to an interlocking mechanism for low-voltage drawer type switch cabinet having the effect of prevention of misoperation and safety action. The interlocking mechanism comprises a fulcrum frame 7, a connecting rod 4, a dowel rod 10, bolts 5, 6, 8, 9. when a switch is locked, a drive rod 2 drives a sliding plate 1 to move upward, making a switch handle 3 move upward, and turning on or off the switch. Simultaneously, the end of the connecting rod 4 is moved upward following the sliding plate 1, but the B end is moved downward, making the dowel rod 10 also move downward, therefore the end can be extended out of a base plate 11. The switch is switched off in an opposite direction; the dowel rod 10 is retracted. The mechanism is of a simple structure, convenient maintenance, safe and convenient operation.
Description
The utility model relates to the link-type operation interlocking gear that having of a kind of low pressure drawer-type switch cabinet prevents the misoperation safety protective action.
In operation, maintenance and the service work of low pressure drawer-type switch cabinet, because the requirement on the electric industry work safety, switch cubicle should have the function of the misoperation of preventing, be that switch can not be pushed into run location from the maintenance position with drawer at closing position, switch can not be pulled to the maintenance position from run location with drawer in the separating brake position.The structural design of the operation interlocking gear that uses is unreasonable at present, much can be malfunctioning after operation in a few years, lose original function, and make troubles for operation, maintenance and the service work of low pressure drawer-type switch cabinet.
The purpose of this utility model is to overcome the deficiency of prior art, and traditional interlocking gear is carried out architecture advances, makes its application, maintenance, maintenance conveniently, handling safety.
The making process of low pressure drawer-type switch cabinet is: during combined floodgate, rotate the operating handle on the low pressure drawer-type switch cabinet door, make drive link 2 motions by transmission mechanism, drive link 2 drives slide plate 1 and moves upward, and makes upwards action of switch handle 3, and switch closes a floodgate.
The purpose of this utility model is achieved through the following technical solutions: during combined floodgate, the A end of connecting rod 4 also follows slide plate 1 to move upward, and the B end then moves downward, and promptly connecting rod 4 clockwise rotates around bolt 8, pin rod 10 is also and then moved downward, and its end stretches out from negative 11 like this.Direction is opposite during separating brake, pin rod 10 withdrawals.
Utilize this mechanism, when switch during at closing position, pin rod 10 stretches out, because its barrier effect can not be pushed into run location from the maintenance position with drawer; When switch during at run location, switch is not separated, pin rod 10 can not be withdrawn, and drawer can not be pulled out.So just protect the safety of operating personnel and equipment, prevented misoperation.
The utility model has following advantage compared with the prior art: this mechanism design is reasonable, and is simple in structure, is easy to safeguard, easy to operate, and various aspects of performance such as safety and maintenance all can meet the demands.This mechanism is made sturdy and durable by steel plate, need not safeguard specially, and save material, has simplified installation, maintenance, maintenance process, has reduced making, maintenance, maintenance, mounting cost.
Accompanying drawing 1 is the utility model operation interlocking gear assembling schematic diagram;
Accompanying drawing 2 is embodiment master, end views of accompanying drawing 1 central bearing point frame 7;
Accompanying drawing 3 is embodiment master, end views of connecting rod 4 in the accompanying drawing 1;
Accompanying drawing 4 is embodiment front views of pin rod 10 in the accompanying drawing 1;
Below in conjunction with accompanying drawing use of the present utility model is elaborated:
The utility model is made up of fulcrum frame 7, connecting rod 4, pin rod 10 and bolt 5,6,8,9.This mechanism action principle is seen Fig. 1.Fulcrum frame 7 is fixed on the switch housing by bolt 6, the A end of connecting rod 4 is fixed on the slide plate 1 by bolt 5, bolt 5 can slide in the A of connecting rod 4 end slotted hole, and the A of connecting rod 4 end can rotate around bolt 5, parts 1,4, can make parallel the moving of slide plate 1 convert the rotation of connecting rod 4 between 5 around bolt 5, the B end of connecting rod 4 is connected with pin rod 10 by bolt 9, bolt 9 can slide in the B of connecting rod 4 end slotted hole, and the B of connecting rod 4 end can rotate around bolt 9, connecting rod 4 is connected by bolt 8 with fulcrum frame 7, and connecting rod 4 can rotate around bolt 8, parts 4,8,9, connecting rod 4 is moved around the straight line that the rotation of bolt 8 converts pin rod 10 to, and guarantee that all the time pin rod 10 is perpendicular with the pin-and-hole of base plate 11.During combined floodgate; drive link 2 drives slide plate 1 and moves upward; make upwards action of switch handle 3, switch closes a floodgate, and the A end of connecting rod 4 and then slide plate 1 moves upward; connecting rod 4 is clockwise rotated around bolt 8; then B end drive pin rod 10 moves downward, and its end stretches out from negative 11 like this, and direction is opposite during separating brake; pin rod 10 withdrawals; utilize this mechanism, when switch during at closing position, pin rod 10 stretches out; because its barrier effect can not be pushed into drawer run location from the maintenance position or when switch during at run location; switch is not separated, pin rod 10 can not be withdrawn, and drawer can not be pulled out; so just protect the safety of operating personnel and equipment, prevented misoperation.
