Abstract
The utility model discloses a vacuum circuit breaker energy storage spring assembly, include: frame, frame, energy -stored spring and pin, bent plate and screw, be equipped with the threaded holes and pinhole on the bent plate, the screw hole has two at least, screw quantity is unanimous with screw hole quantity, the screw passes the screw hole, be fixed in the frame with the bent plate on, on energy -stored spring one end is fixed in the frame, the other end connects the pin, the pin passes the pinhole and is connected as an organic wholely with the bent plate. The utility model discloses changed the structure of pin direct mount on the frame, utilized the bent plate and the screw that increase to cooperate to one person's power is fixed the energy -stored spring on the frame, makes the installation of energy -stored spring more economize manual work and laborsaving, and promoted the factor of safety of installation.
Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances field, relates in particular to a kind of vacuum circuit-breaker energy-stored spring device.
Background technology
Along with the progress of technology, energy-stored spring is more and more common in High-Voltage Electrical Appliances field as a kind of circuit breaker operation mechanism, and the operating mechanism of energy-stored spring adopts manually or electric operating, has higher closing speed, and can realize automatic reclosing.In practice, energy-stored spring one end of vacuum circuit-breaker is fixed on support, the other end is connected on the framework on support top by pin, and spring spring body slightly stretches and makes its installation length L1 be greater than its natural length L.The energy accumulation spring mechanism of this traditional structure when mounted, needs at least 3 people, wherein 1 people's stable frame, and 1 people keeps stretching energy-stored spring, and pin pierces into and is fixed on framework by last 1 personal responsibility, and this mounting means had both been taken a lot of work effort, also dangerous.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of vacuum circuit-breaker energy-stored spring device.
Its concrete technical scheme adopted is as follows:
A kind of vacuum circuit-breaker energy-stored spring device, comprising: support, framework, energy-stored spring, pin, bent plate and screw; Described bent plate is provided with screwed hole and pin-and-hole, described screwed hole has two at least, described screw number is consistent with screwed hole quantity, described screw passes screwed hole, is fixed on framework by bent plate, described energy-stored spring one end is fixed on support, other end connecting pins, and described pin connects as one through pin-and-hole and bent plate.
By adopting this technical scheme: when carrying out energy-stored spring and installing, be first connected on energy-stored spring by pin, and through the pin-and-hole on bent plate, both are connected on pin.Then, to screw in the screwed hole on bent plate with a longer screw through framework, with this, primary stretching is carried out to spring; Then, the screw that precession is shorter in another screwed hole, the screw that taking-up first is longer simultaneously, carries out secondary stretching to spring, and the bent plate the most at last that so circulates is fixed on framework.Thus, utilize the bending plate that increases and screw to match, achieve the technique effect be easily fixed on by this energy accumulation spring with 1 people on framework.The improvement of this mounting means, makes the installation of energy accumulation spring both save labor, safety again.
Preferred scheme is, in above-mentioned vacuum circuit-breaker energy-stored spring device: described bent plate is U-shaped, described screwed hole has 4, lays respectively at the corner of bent plate bottom surface, and described pin-and-hole is positioned on the two sides of bent plate.
Compared with prior art, the utility model changes the structure be directly installed on by pin on framework, the bent plate of increase and screw is utilized to match, with the power of a people, energy-stored spring is fixed on framework, make the installation process of energy-stored spring more less manpower and laborsaving, and improve the coefficient of safety of installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the energy-stored spring mechanism of prior art.
In above-mentioned accompanying drawing each component names and component names corresponding relation as follows:
1, support; 2, framework; 3, energy-stored spring; 4, pin; 5, bent plate; 6, screw; Screwed hole; 52, pin-and-hole.
Embodiment
Below in conjunction with instantiation, the utility model is further described.
Embodiment 1 of the present utility model as shown in Figure 1:
A kind of vacuum circuit-breaker energy-stored spring device, comprise: support 1, framework 2, energy-stored spring 3 and pin 4, bent plate 5 and screw 6, described bent plate 5 are provided with screwed hole 51 and pin-and-hole 52, described bent plate 5 is U-shaped, described screwed hole 51 has 4, lay respectively at the corner of bent plate 5 bottom surface, described pin-and-hole 52 is positioned on the two sides of bent plate 5.Described screw 6 quantity is consistent with the quantity of screwed hole 51, described screw 6 passes screwed hole 51, is fixed on framework 2 by bent plate 5, described energy-stored spring 3 one end is fixed on support 1, other end connecting pins 4, and described pin 4 connects as one through pin-and-hole 52 and bent plate 5.
Energy-stored spring mechanism of the prior art shown in comparison diagram 2, the distinctive points of embodiment 1 is: pin 4 is not directly installed on framework 2, but is first arranged on bent plate 5, and then bent plate 5 is fixed as one by screw 6 and framework 2.
The technique effect that such structure is brought is: in the practice process carrying out energy-stored spring installation: be first connected on energy-stored spring 3 by pin 4, and through the pin-and-hole 52 on bent plate 5, both is connected on pin 4.Then, on bent plate 5 with a longer screw 6 through the screwed hole 51 on precession bent plate 5, in process, primary stretching is carried out to energy-stored spring 3; Then, the screw 6 that precession is shorter in the screwed hole 51 at diagonal angle, bent plate 5 bottom surface, exits first longer screw 6 simultaneously, carries out secondary stretching, so circulate, be finally fixed on framework 2 by bent plate 5 with screw 6 energy-stored spring 3.
Should be understood that; the above; be only specific embodiment of the utility model; but protection range of the present utility model is not limited thereto; the technical staff of any skilled is in technical scope disclosed in the utility model; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Protection range of the present utility model is as the criterion with the protection range of claims.
