Abstract
The utility model relates to a spring box, in particular to a spring box for a coil pressing device, which comprises a seat cover provided with a cavity at high altitude; the bottom of the seat cover is provided with a bottom plate; a spring washer is arranged in the cavity of the seat cover; an upper pressing plate is pressed on the spring washer; and the upper pressing plate and the seat cover are fixed. The spring box has simple structure and stable compression effect.
Description
Technical field
The utility model relates to a kind of spring box, particularly a kind of spring box that is used for the transformer coil hold down gag.
Background technology
Spring box of the prior art generally all is that artificial mode is operated, and the force value instability between spring washer and the insulating part goes wrong insulating part easily, and what cause that coil compresses is insecure.
Summary of the invention
The utility model technical issues that need to address are, have overcome the deficiencies in the prior art part, provide a kind of contraction that makes the insulating part in the transformer to be subjected to the spring box that is used for coil compressing device of the pressure of butterfly spring packing ring all the time.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spring box that is used for coil compressing device includes a cover for seat that is provided with cavity, and the bottom of cover for seat is provided with base plate, is provided with spring washer in the cavity of described cover for seat, is crimped with top board on the spring washer, and top board and cover for seat fix.Top board is exactly described insulating part, and screw rod is to be used for compressing, and when winding during in drying, insulating part shrinks the pressure that is subjected to the butterfly spring pad all the time, and this effect is better when waiting winding dry.
As preferably, also be provided with last item on the described top board, the tube wall of last item and cover for seat fixes.
As preferably, the two ends of described last item are provided with screw rod, and the tube wall of last item and cover for seat is fixedly connected by screw rod.
As preferably, described spring washer is the butterfly spring packing ring.
Therefore, the spring box that is used for coil compressing device described in the utility model, simple in structure, compression effectiveness is stable.
