Abstract
The invention discloses a built-in spring device. A conductive base has an inverted-T-shaped structure. A shaft sleeve goes through a hole in a vertical plate of the conductive base and is arranged symmetrically left and right. Cover plates are arranged at outer rings at the left end and the right end of the shaft sleeve. The cover plates at the left end and the right end of the shaft sleeve are arranged symmetrically in a ][ shape. A spring is arranged in an inner hole of the shaft sleeve. A double-head bolt is arranged in the spring. Two ends of the double-head bolt screw the spring tightly through pads and nuts. The spring is made of stainless steel materials. The length of the spring after compression is more than the length of the shaft sleeve. The length of the spring exposed from the shaft sleeve after compression is less than one third of the width of the cover plate. The spring is arranged inside the shaft sleeve, pollution can be prevented, the assembling process is simple, the usage performances are raised, the cost is lowered, the built-in spring device has good stability for devices working for a long time, the service life is prolonged, and popularization and application has good economic and social benefits.
Description
Technical field
The invention belongs to electric power system accessory field, particularly the built-in spring assembly of one.
Background technology
At present, the indoor isolator contact knife contact spring used in electric power system is mostly external-compression type structure, the spring part of isolating switch generally plays contact at upper current-carrying part and acts on closely, it is the important part of isolating switch, but due to spring part long term exposure in atmosphere, expose to the weather, spring oxidation corrosion or cause heating annealing by assorted dust pollution, himself material changes, elasticity reduces, thus cause contact knife clamping force to reduce, contact resistance increases, the vicious circle of final formation contact heating aggravation, properties of product obviously reduce, if things go on like this, current-carrying part can be caused to burn.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above.
The object of the present invention is achieved like this: built-in spring assembly, comprise conductive seat, axle sleeve, it is characterized in that: described conductive seat is " ┻ " shape structure, axle sleeve is symmetrically arranged through behind the hole on conductive seat riser, the outer ring at two ends, axle sleeve left and right is provided with cover plate, the cover plate at two ends, axle sleeve left and right becomes " ］ ［ " shape symmetrical configuration to arrange, is provided with spring in the endoporus of axle sleeve.
Be provided with stud in described spring, spring is all tightened by pad, nut by the two ends of stud.
Described spring adopts stainless steel.
Length after described spring-compressed is greater than the length of axle sleeve.
The length exposing axle sleeve after described spring-compressed is less than 1/3rd of cover plate width.
Spring is built in axle sleeve by the present invention, and energy preventing pollution, assembly technology is simple, improves serviceability, reduces cost, for the equipment of long-term work, have good stability, extend useful life, apply and have good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present invention.
In figure: 1. conductive seat; 2. cover plate; 3. spring; 4. axle sleeve.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, but not as limitation of the present invention:
Built-in spring assembly, comprise conductive seat 1, axle sleeve 4, described conductive seat 1 is " ┻ " shape structure, axle sleeve 4 is symmetrically arranged through behind the hole on conductive seat 1 riser, the outer ring at axle sleeve about 4 two ends is provided with cover plate 2, cover plate 2 one-tenth " ］ ［ " shape symmetrical configuration at axle sleeve about 4 two ends is arranged, is provided with spring 3 in the endoporus of axle sleeve 4; Be provided with stud in described spring 3, spring 3 is all tightened by pad, nut by the two ends of stud.
Described spring 3 adopts stainless steel, carries out antiseptic and rustproof process; Length after described spring 3 compresses is greater than the length of axle sleeve 4; Described spring 3 exposes axle sleeve 4 length after compressing is less than 1/3rd of cover plate 2 width.
Obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all execution modes, and thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
