Abstract
The invention discloses a breaker welded crank arm comprising a top connecting portion, an arm body, and a bottom connecting portion. The arm body is a cuboid the lower part of which is equipped with a shaft hole. The bottom connecting portion is a cylinder and the diameter of the left end of the cylinder is less than that of the right end of the cylinder. The top connecting portion is a cylinder and the diameter of the left end of the cylinder is less than that of the right end of the cylinder. The right end face of the top connecting portion is welded on the left side of the upper part of the arm body. The top surface of the arm body is lower than the top face of the top connecting portion. The left end of the bottom connecting portion passes through a shaft hole on the lower part of the arm body from right to left. The bottom connecting portion is welded on a position where the bottom connecting portion and the shaft hole contact. The axis of the bottom connecting portion and the axis of the shaft hole are arranged in a same straight line. The axis of the top connecting portion and the axis of the bottom connecting portion are in parallel and are located at the central surface of the arm body. The breaker welded crank arm is simple in structure, easy to operate, and good in stability.
Description
Technical field
The present invention relates to field of circuit breakers, relate in particular to a kind of breaker welding connecting lever field.
Background technology
Connecting lever is one of parts conventional in machinery equipment, is connected to realize related motion by screw with other partsEtc. function. In breaker, the stability influence of connecting lever is to close switch insurance fusing or the loose contact of breakerAnd cause closing coil short circuit, and form like this electric loop fault, finally cause primary cut-out not closeConsequence, the unstable complex manufacturing that also can cause of connecting lever in addition, manufacturing cost increase.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of the invention is: a kind of Stability Analysis of Structures is provided, superior performanceBreaker welding connecting lever. The technical solution used in the present invention is:
A kind of breaker welding connecting lever, comprises connecting portion, and arm body and lower connecting portion, is characterized in that: described arm bodyFor cuboid, its lower end is provided with axis hole, and described lower connecting portion is cylindrical body, and left end diameter to be less than right-hand member straightFootpath, described upper connecting portion is cylindrical body, and left end cylindrical body diameter is less than right-hand member cylindrical body diameter, described onConnecting portion right side is welded on the left side that arm is held with it, and arm is surperficial lower than the highest of upper connecting portion with it, instituteState lower connecting portion left end right-to-left through the axis hole of arm body lower end, described lower connecting portion with the contacting of axis holePosition welding, the axis of described lower connecting portion axis and axis hole is located along the same line, described upper connecting portion axleLine is parallel with lower connecting portion axis, and is positioned on the median plane of arm body.
Further, described lower connecting portion right-hand member is provided with a groove.
Further, described lower connecting portion surface is provided with chamfering with end face intersection.
Further, described upper connecting portion left end is provided with a cavity.
Further, described upper connecting portion left end outer surface is provided with some through holes, and the axis of described through hole is positioned at sameOne plane.
Further, described through hole number is 4, and symmetrical, and the angle of described adjacent through-holes is 30 °.
Further, described upper connecting portion left end is provided with several height grooves.
Further, the distance of described upper connecting portion axis and lower connecting portion axis is 58mm.
Compared with prior art, its beneficial effect is in the present invention:
Pass through welding by upper connecting portion and arm body, lower connecting portion is through the axis hole of arm body lower end and also welding, upper companyConnect portion's axis parallel with lower connecting portion axis, and be positioned on the median plane of arm body, establish recessed at lower connecting portion right-hand memberGroove, upper connecting portion left end is established height groove, and this simple in structure, easy operating, is rigidly connected and makes connectionPortion, arm body, lower connecting portion position are relatively constant, thereby have ensured stability and the reliability of welding connecting lever,Improved the mechanical strength of connecting lever, this connection and the structure setting to upper connecting portion and lower connecting portion also makeObtain breaker and be more conducive in the course of the work divide-shut brake.
