Abstract
The utility model provides a keyboard return spring. The spring comprises a deformation main body and a shell wrapping the entire deformation main body. Main body cover sheets are arranged on two ends of the deformation main body. The deformation main body is in a spiral shape with more than one spiral ring, each of which is a circle with the same diameter. The rings extend outwards in a spiral manner along the same center line at the same intervals to form the deformation main body. There are two pieces of the cover sheets, including a first cover sheet and a second cover sheet. The shell is in a cylindrical shape with the same height as the deformation main body and a diameter larger than that of the deformation main body, and the entire shell is a through hole which is hollow inside. The spring is good in stability, easy to install, and large in contact area.
Description
Technical field
The utility model relates to a kind of back-moving spring of keyboard.
Background technology
In today of industrial develop rapidly, the mankind more and more pursue simply, efficient and performance.Electronic and information industry fast development, computer as the representative industry of electronic and information industry be more in decades at a tremendous pace, short development and popularity rate far beyond people's the imagination.Keyboard is as requisite input tool in computer, also constantly perfect in development at full speed.On traditional keyboard, mostly adopt balancing pole to control the bounce-back after pressing, although the cost compare of balance is low, during use, also can reach qualified effect, can contact area considerably less due to balancing pole, the volume of itself is also very little, when installing, just to installation, bring very large difficulty like this, although and balancing pole has certain rebound reset function, can not professional back-moving spring after all, and because volume is little, contact area is few, be easy to occur to slide and displacement, the non-constant of stability.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of good stability is provided, the back-moving spring of the easy for installation and keyboard that contact area is large.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A back-moving spring for keyboard, comprises distortion main body, and the two ends of described distortion main body are provided with main body cover plate, and in the shape of a spiral, spring also comprises the shell in whole distortion main body is wrapped in to main body.
As preferably, described cover plate has two, is divided into the first cover plate and the second cover plate.
As preferably, described the first cover plate is positioned at the upper end of main body, and the second cover plate is positioned at the lower end of main body.
As preferably, the diameter of described cover plate equals the diameter of main body.
As preferably, described shell is cylindrical, and centre is hollow, and integral body is through hole shape.
As preferably, the height of shell equals the height of main body, and housing diameter is greater than the diameter of main body.
As preferably, described main body is comprised of along the outside spiral extension of same center line by same ratio more than one round screw thread circle body.
As preferably, the diameter of each round screw thread circle body is all identical.
The utility model is provided with shell and cover plate; under the protection of shell; the situation that just spring gryposis can not occur or be shifted suddenly; effectively guaranteed the stability of spring; the design of cover plate allows back-moving spring when installing and use; can be convenient with equipment connection on, also allow equipment while using touch completely with Compress Spring.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of the back-moving spring of a kind of keyboard of the utility model;
Fig. 2 is the vertical view of the back-moving spring of a kind of keyboard of the utility model.
In figure: 1, shell; 2, distortion main body; 20, spiral circle body; 21, cover plate.
Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Consult shown in Fig. 1 to Fig. 2, a kind of back-moving spring of keyboard, comprises distortion main body 2, and the shell 1 in whole distortion main body 2 is wrapped in; The two ends of described distortion main body 2 are provided with main body cover plate 21, and described main body 2 in the shape of a spiral, is comprised of along the outside spiral extension of same center line by same ratio more than one round screw thread circle body 20, and the diameter of each round screw thread circle body 20 is all identical; Described cover plate 21 has two, is divided into the first cover plate and the second cover plate; Described shell 1 is cylindrical, highly equals the height of main body 2, and the diameter of shell 1 is greater than the diameter of main body 2, and centre is hollow, and integral body is through hole shape.
The diameter of described cover plate 21 equals the diameter of main body 20, and described the first cover plate is positioned at the upper end of main body 20, and the second cover plate is positioned at the lower end of main body 20.
The beneficial effects of the utility model are: because the back-moving spring of keyboard is provided with shell and cover plate; under the protection of shell; the situation that just spring gryposis can not occur or be shifted suddenly; effectively guaranteed the stability of spring; the design of cover plate allows back-moving spring when installing and use; can be convenient with equipment connection on, also allow equipment while using touch completely with Compress Spring.
In the description of this specification, the description of reference term " embodiment ", " example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiment or example.
