Abstract
The utility model relates to an overhaul tool for electric appliances and equipment and particularly relates to a spring replacement tool for a circuit breaker. The tool comprises a screw rod and a screw nut matched with the screw rod and is characterized in that the screw nut is rectangular plate-like, a positioning shaft penetrates through the rectangular plate-like screw nut and a moving block same as the rectangular plate-like screw nut in shape, one end of the screw rod pushes against one side of the moving block, a handle for rotation is fixedly arranged at the other end of the screw rod, and a spring fixing block is mounted on one side of the rectangular plate-like screw nut, which corresponds to the moving block. According to the technical scheme disclosed by the utility model, the rotation motion of the screw rod is changed to the linear movement of the moving block, and a spring in the circuit breaker is expanded for assembly and disassembly by virtue of the spring fixing block which is matched with the spring of the circuit breaker to be disassembled and assembled. The device has the characteristics of reasonable structure, convenience in use, capability of effectively improving the replacement efficiency of the spring by above 10 times and the like.
Description
Technical field
The utility model relates to a kind of electric equipment service kit, and particularly a kind of breaker spring is changed instrument.
Background technology
Fast development along with electric power; Present most of circuit breaker all adopts spring mechanism; Spring mechanism with its reliable in action, safeguard simple and the replacement liquid press mechanism; Use the back fatiguability for a long time but the weak point of spring mechanism is a spring, thereby cause circuit breaker branch, closing speed not to reach specification requirement, need to change spring.The circuit breaker of spring mechanism is because its compact layout causes spring replacing space narrow and small, and staff can't stretch into; Can't spring be elongated; Cause when changing working expenditure, effort, even if those of skill in the art change a spring also to a little 2-3 hours, unskilled personnel are just consuming time more; And can finger scuffing, extruding badly just take place, damage elements such as spring, axle sleeve sometimes.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, provides a kind of replacing spring rapidly, fast, and breaker spring rational in infrastructure is changing device more.
For the technical scheme that realizes above-mentioned purpose is: a kind of breaker spring is changed instrument; Comprise leading screw and the nut that matches with leading screw; It is characterized in that nut is tabular with rectangle, locating shaft pass the tabular nut of rectangle with the identical movable block of the tabular nut shape of rectangle, an end of leading screw withstands on a side of movable block; The other end of leading screw is fixed with rotation and uses handle, at tabular nut of rectangle and the corresponding side of movable block the spring fixed block is installed.
Above-mentioned spring fixed block is tabular, has " C " shape opening above that.
Above-mentioned spring fixed block is that screw is connected or other removably connects with the installation form of tabular nut of rectangle and movable block.
The contact-making surface of above-mentioned leading screw and movable block is spherical.
The technical scheme of the utility model is to utilize the leading screw straight line that becomes movable block that will rotatablely move to move, and the spring fixed block through the breaker spring with the need dismounting matches struts the spring in the circuit breaker, is used for dismounting and installs.It is rational in infrastructure, easy to use that this device has, and can effectively improve spring and change 10 times of efficient with first-class characteristics.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the left view of the utility model accompanying drawing 1.
Embodiment
Like accompanying drawing 1, shown in 2; On the tabular nut 5 of the rectangle of right-hand member, associated leading screw 3 is installed; The movable block 1 identical with the tabular nut shape of rectangle arranged in the left side of the tabular nut of rectangle; Locating shaft 2 passes tabular nut of rectangle and movable block, and tabular nut of rectangle and movable block can be moved along the locating shaft straight line.The left end of leading screw withstands on the right flank of movable block, and for reducing the frictional resistance between leading screw and the movable block, the contact-making surface of leading screw and movable block is spherical.At tabular nut of rectangle and the corresponding upside of movable block spring fixed block 7 is installed; The spring fixed block is tabular; Have " C " shape opening above that; Be the spring in the circuit breaker that adapts to the dismounting different size, above-mentioned spring fixed block is that screw 8 is connected or other removably connects with the installation form of tabular nut of rectangle and movable block.
During use, " C " shape opening on the two spring fixed blocks is inserted in the spring 4, with handle 6 rotating threaded shafts, promote movable block by leading screw and move right, spring is strutted, can the spring in the circuit breaker be pulled down taking-up through the rotation on the leading screw.Identical with said process during installation, existing good spring inserts in " C " shape opening on the fixed block, and rotating threaded shaft struts spring and then the spring that struts is installed in the circuit breaker, and the reverse rotation leading screw takes out this device and gets final product.
