Abstract
The utility model relates to an energy storage spring mechanism for an operating mechanism of a circuit breaker. The energy storage spring mechanism comprises a spring support, two energy storage springs sleeved on two guide rods of the spring support, a supporting plate which is sleeved on the two guide rods of the spring support in a penetrating manner and can support the two energy storage springs, fixing plates and a shaft, wherein the shaft penetrates the spring support and the fixing plates and supports the supporting plate; a single-spring supporting plate supporting the lower end of the energy storage spring is arranged between the lower part of each energy storage spring and the supporting plate, and four bends are respectively formed at four edges of each single-spring supporting plate; a round hole allowing a long pin to penetrate is formed at the lower part of each guide rod of the spring support; and the upper surface of the supporting plate is flat. The above structure takes full account of the space of the operating mechanism of the circuit breaker, and enables the energy storage springs to be modularized and conveniently mounted through adding fabrication holes; as the upper surface of the supporting plate is flat, the processing technology of cold-punching a lug boss is omitted; the thickness is increased to improve the strength; the two single-spring supporting plates are added; and therefore, the strength is enhanced through optimal design of the supporting plate, and the mechanical service life is prolonged.
Description
Technical field
The utility model belongs to a kind of parts of circuit breaker, particularly relates to a kind of energy-stored spring mechanism of circuit breaker operation mechanism.
Background technology
Shortcomings such as the energy-stored spring mechanism of circuit breaker operation mechanism needs special-purpose mold for directly on operating mechanism, installing usually at present, and assembly technology is complicated, and it is big to take up room.In addition, rupture easily through life test, make its circuit breaker close not brake application as the supporting plate that can hold two energy-stored springs of energy-stored spring mechanism.And on this supporting plate, enclose and prevent two energy-stored spring translations and be provided with a plurality of convexities that therefore hard processing cost of supporting plate material is higher again.This is the circuit breaker miniaturization, a technical barrier in the high life design.
Summary of the invention
The utility model can be saved the operating mechanism space with the energy-stored spring mechanism moduleization for the technical problem that exists in the solution known technology provides a kind of, improves the energy-stored spring mechanism of the circuit breaker operation mechanism in life-span.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: it includes spring support, two and is sleeved on energy-stored spring on two guide rods of said spring support, is set on supporting plate, fixed head and the axle that can hold said two energy-stored springs on two guide rods of said spring support; Described axle passes in spring support and the fixed head and supports described supporting plate; A single spring bracket plate of holding this energy-stored spring lower end is respectively arranged below described each energy-stored spring and between the described supporting plate, a bending that prevents said energy-stored spring translation is respectively arranged on the four direction of described single spring bracket plate; Respectively there is one can penetrate the circular hole of having strong market potential in the guide rod bottom of described spring support; The described upper surface of holding the supporting plate of said two energy-stored springs is the plane.
Advantage and the good effect that the utlity model has are: this structure has taken into full account the circuit breaker operation mechanism space, can be with the energy-stored spring modularization, and make it easy to install through increasing fabrication hole; Can be the plane above the supporting plate of holding two energy-stored springs of the present invention, save the processing technology of cold punching boss, and can increase thickness; Improved the intensity of supporting plate; And the design that two single spring bracket plates have been arranged, increased intensity through optimal design like this to supporting plate, improved mechanical endurance.

Fig. 3 is the perspective view of single spring bracket plate.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Like Fig. 1,2, shown in 3; On two guide rods 7 of spring support 1, respectively be set with an energy-stored spring 2; A single spring bracket plate 3 of holding these energy-stored spring 2 lower ends is respectively arranged below each energy-stored spring 2, have in the centre on the four direction of single spring bracket plate 3 in the hole that can pass guide rod 7 bending that prevents energy-stored spring 2 translations is respectively arranged; Be the supporting plate of holding two single spring bracket plates 34 that is set on two guide rods 7 below single spring bracket plate 3 on two guide rods 7, the upper surface of supporting plate 4 is the plane; Guide rod 7 bottoms at spring support 1 respectively have one can penetrate the circular hole of having strong market potential; Axle 5 passes in spring support 1 and the fixed head 8 and supports supporting plate 4.
Like Fig. 1, shown in 2, the energy-stored spring 2 of the utility model is inserted in and is inserted in single spring bracket plate 3, supporting plate 4 behind the spring support 1 again, makes energy-stored spring 2 compressions through mold pressing palette 4, and axle 5 passes in spring support 1 and the fixed head 8 and supports supporting plate 4.Compress supporting plate 4 once more, axle 5 moves the aperture that exposes diameter 3mm until spring support 1 together with one of which, and pin 6 passes this hole and supports axle 5, and the power of this parts energy-stored spring 2 all acts on the pin 6.These pin 6 effects are to make energy-stored spring 2 compressions one segment distance, are convenient to like this install.Fixed head 8 is connected with lever in the operating mechanism, and energy storage is withstood axle 5 through lever and come compressed energy-storage spring 2, can take out pin 6 after energy-stored spring 2 is compressed.Thereby the energy-stored spring mechanism that makes circuit breaker operation mechanism has realized a modular independent global facility, wherein sells 6 and has solved the difficult problem of assembling effectively.In addition the design limit of single spring bracket plate 3 position of energy-stored spring 2, energy-stored spring 2 balance in guide rod 7 is moved.
