Abstract

The utility model provides a circuit breaker operation link rod mechanism, including operation link rod and bearing structure, bearing structure sets up in operation link rod's middle part, and operation link rod is supported fixedly by bearing structure. In order solving current operation link rod owing to reasons such as self gravity can produce, the difficult connecting rod spread groove of aiming at on the outside switch when docking once more, the operation is inconvenient, and makes operation link rod produce easily to warp, just if things go on like this need change operation link rod again, cause the wasting of resources, improvement cost scheduling problem. The utility model belongs to the circuit breaker field.

Description

A kind of breaker operator linkage

Technical field

The utility model relates to a kind of linkage, belongs to distribution control field.

Background technology

Breaker in existing distribution box, external switch is in transmission connection by operator link and breaker control end, thereby, can be by the Kai Heguan of operator link control breaker by controlling external switch, but because the two ends of operator link are connected with breaker with external switch respectively, in the time of opening operation plate face, console switch can be along with operation panel be towards outer motion, operator link must have one end and separate, what existing switch board designed is that operator link position remains unchanged, when each shutoff operation plate face, connecting rod link slot on external switch (being operating grip) all needs again to dock with the end of operator link, and due to the reason of operator link self gravitation and respective support structure is not set, operator link has certain sinking after separating with the connecting rod link slot on external switch, while again docking, operator link is difficult for aiming at the connecting rod link slot on external switch, operation inconvenience, and easily make operator link produce distortion, if things go on like this just need to again change operator link, cause the wasting of resources, raise the cost.

Summary of the invention

The purpose of this utility model is: a kind of breaker operator linkage is provided, to solve existing operator link because the reasons such as self gravitation can produce sinking, while again docking, be difficult for aiming at the connecting rod link slot on external switch, operation inconvenience, and easily make operator link produce distortion, if things go on like this just need to again change operator link, cause the wasting of resources, the problem such as raise the cost.

For addressing the above problem, intend adopting so a kind of breaker operator linkage, comprise operator link and supporting construction, described supporting construction is arranged at the middle part of operator link, and operator link is fixed by support construction supports.

Described supporting construction is the gripper shoe arranging along vertical, offers through hole in supporting construction, and described operator link along continuous straight runs is arranged in through hole.

The diameter of through hole is greater than the maximum outside diameter of operator link, and the two difference≤2mm.

The utility model compared with prior art, major advantage is to add cartridge support structure at the middle part of operator link, avoid the problem offseting downward due to the effect of operator link self gravitation, thereby avoid in the time of shutoff operation panel, the operator link distortion cannot alignment function link end causing due to the connecting rod link slot on external switch, and use more conveniently, without often changing connecting rod, reduce costs.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below with reference to accompanying drawings the utility model is described in further detail,

Embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, the present embodiment provides a kind of breaker operator linkage, comprise operator link 1 and supporting construction 2, described supporting construction 2 is the gripper shoe arranging along vertical, in supporting construction 2, offer through hole 21, supporting construction 2 is arranged at the middle part of operator link 1, and operator link 1 along continuous straight runs is arranged in through hole 21, and the slightly larger in diameter of through hole 21 is in the maximum outside diameter (difference≤2mm) of operator link 1.
