Abstract
The utility model discloses an extension spring formula clip, which comprises a body, body essence is a small -size tension springs, tension springs's annular spring wire around two rings center windings, wherein be provided with an uplift circular arc on the spring wire of round, two ports of tension springs do all that the circular arc is smooth to be handled, tension springs's spring wire be the cylinder shape, its transverse section is circular, tension springs form for integrative process casting, wherein, dependence tension springs's tensile elasticity function, the clip not only can keep compressing the laminating state under normal condition, can easily pull open it moreover, insertion paper between two rings of spring wire, then loose one's grip, tension springs resumes the compression state that laminates at once. In this way, the utility model discloses simple structure, novel unique, combine the clip with tension springs's tensile elasticity characteristic ingeniously on, incessantly paper can not pressed from both sides to long -term the use yet, and is durable, long service life, the practicality is strong, has great economic benefits and market prospect.
Description
Technical field
The utility model relates to spring art, particularly relates to a kind of Extension Spring-type clip.
Background technology
Clip and paper clip, be used to the apparatus of the curved holding paper sheet made of inflection, at present, existing clip is almost the bent wire of a bit of holding paper, then in wire surface nickel plating, for prior art, this clip is short for service life, be almost disposable, ductility wiry is good, is easy to cause bending, and paper after a while, clip will landing, and compactness is not strong.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of Extension Spring-type clip, still can keep elasticity after Long-Time Service, can firmly clamp paper not landing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of Extension Spring-type clip, it is characterized in that, comprise: body, described body essence is a small-sized tension spring, the ring spring wire-wound center of described tension spring is wound around two circles, wherein a spring wire enclosed is provided with a protuberance circular arc, two ports of described tension spring all make circular arc smooth treatment, the spring wire of described tension spring is cylindrical shape, its lateral cross section is circular, and described tension spring is integrated processing casting and forms; Wherein, rely on the tensile elasticity function of tension spring, clip can not only keep compressing fit-state under normal circumstances, and can easily pull open it, between two coil spring lines, sandwich paper, then loose one's grip, tension spring recovers compressive state of fitting at once.
In the utility model preferred embodiment, it is stainless steel that described body makes material, ovalize.
In the utility model preferred embodiment, the long 3cm of this described long axis of body, the long 1.5cm of minor axis.
In the utility model preferred embodiment, the wire diameter of described tension spring is 1mm.
In the utility model preferred embodiment, two coil spring lines of the winding of described tension spring overlap.
The beneficial effects of the utility model are: the utility model structure is simple, novel unique, are attached on clip dexterously by the tensile elasticity characteristic of tension spring, Long-Time Service also can not can't clip paper, durable, long service life, practical, there are larger economic benefit and market prospects.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of Extension Spring-type clip one of the utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1-body, 2-tension spring, 3-swell circular arc.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of Extension Spring-type clip, it is characterized in that, comprise: body 1, described body 1 essence is a small-sized tension spring, and the ring spring wire-wound center of described tension spring 2 is wound around two circles, wherein a spring wire enclosed is provided with a protuberance circular arc 3, two ports of described tension spring 2 all make circular arc smooth treatment, the spring wire of described tension spring 2 is cylindrical shape, and its lateral cross section is circular, and described tension spring 2 is integrated processing casting and forms; Wherein, rely on the tensile elasticity function of tension spring 2, clip can not only keep compressing fit-state under normal circumstances, and can easily pull open it, between two coil spring lines, sandwich paper, then loose one's grip, tension spring 2 recovers compressive state of fitting at once.
Be different from prior art.
In another embodiment, it is stainless steel that described body 1 makes material, ovalize, and stainless steel is corrosion-resistant, wear-resistant, long service life.
In another embodiment, the described long 3cm of body 1 major axis, the long 1.5cm of minor axis, moulding is small and exquisite, does not take up space.
In another embodiment, the wire diameter of described tension spring 2 is 1mm.
In another embodiment, two coil spring lines of the winding of described tension spring 2 overlap, and when ensureing that spring relies on its compressibility to clamp paper, bilevel spring coil fits, but not straggly, and guarantee will cause fold to damage to paper.
The utility model structure is simple, novel unique, dexterously the tensile elasticity characteristic of tension spring is attached on clip, rely on the tensile elasticity function of tension spring, clip can not only keep compressing fit-state under normal circumstances, and can easily pull open it, from the protuberance circular arc on spring wire, between two coil spring lines, sandwich paper, then loose one's grip, tension spring recovers compressive state of fitting at once, Long-Time Service also can not can't clip paper, durable, long service life, practical, there are larger economic benefit and market prospects.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
