Abstract
A device for adjusting the pre-pressing quantity of openings spring comprises an opening spring and a pressed block limited at the end of a spring shell body, wherein the pressed block is connected with a bracket which extends outside the end of the spring shell body. The device is characterized in that the bracket is connected with the pressed block through a thread spinning component. The devicehas the advantages of simple and compact structure, reliable work and the like, can effectively avoid the affection to the opening speed of breakers owing to the limitation of the spring manufacturing level, the environmental temperature and the like.
Description
Technical field
The utility model relates to a kind of adjusting device that is used for the electric spring operation machine tripping spring precompressed amount of circuit breaker.
Background technology
Be not used in the device of regulating tripping spring precompressed amount in the electric spring operation machine of original circuit breaker, as shown in Figure 1, because restriction of spring manufacture level and ambient temperature etc. exert an influence to breaker open operation speed, often, cause the very big loss of human and material resources because of the opening velocity more converting mechanism tripping spring that goes beyond the scope repeatedly.
Summary of the invention
The purpose of this utility model provides a kind of device of scalable electric spring operation machine tripping spring precompressed amount, can effectively offset because restriction of spring manufacture level and ambient temperature etc. to the influence that breaker open operation speed causes, make opening time reach the specification requirement of circuit breaker.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of device of adjusting tripping spring precompressed amount comprises tripping spring and is subject to the briquetting of spring housing end that briquetting connects the bracket that stretches out outside the spring housing end, it is characterized in that, is connected by a slash member between described bracket and the briquetting.
In the such scheme, described slash member comprises a screw rod that is installed with clamp nut, and an end of this screw rod connects bracket, and the other end is connected with briquetting by the spring housing end, and described screw rod is threaded with a thread bush.
The utlity model has advantages such as simple in structure, compact, reliable operation.Overcome such mechanism in cooperating the body process of the test, often because of the opening velocity more shortcoming of converting mechanism tripping spring that goes beyond the scope repeatedly.
Description of drawings
Fig. 1 is original cylindrically coiled spring structure chart in the electric spring operation machine.
Fig. 2 is an installation diagram of the present utility model.
Fig. 3 is the tripping spring structure figure that has the utility model device.
Among Fig. 1 to Fig. 3: 1, bracket; 2, clamp nut; 3, thread bush; 4, briquetting.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 2, shown in Figure 3, a kind of device of adjusting tripping spring precompressed amount comprises tripping spring and is subject to the briquetting 4 of spring housing end that briquetting connects the bracket 1 that stretches out outside the spring housing end, is connected by a slash member between bracket and the briquetting.The slash member comprises a screw rod that is installed with clamp nut 2, and an end of this screw rod connects bracket 1, and the other end is connected with briquetting 4 by the spring housing end, and screw rod is threaded with a thread bush 3.
This compact conformation, practicality.Can pass through thread bush 3 spinning left, change the initial precompressed position of tripping spring, adjustable range is A (Fig. 3), thereby realizes regulating the initial precompression of cylindrically coiled spring.
The utility model can effectively be offset owing to the influence to breaker open operation speed such as restriction of spring manufacture level and ambient temperature.And join an amount of adjusting that circuit breaker provides opening velocity for it, satisfied technical conditions of joining circuit breaker have been reduced or remitted the secondary of such mechanism or even have repeatedly been changed tripping spring.Thereby effectively raise the efficient of joining examination, reduced maintenance costs such as maintenance cost, fee of material.
Claims (2)
