The invention relates to a key with a balancing device, which comprises a keycap and at least one balancing elastic member, wherein the back of the keycap is equipped with a clamping portion, the balancing elastic member used to support the keycap is provided with a fixing portion and two arc-shaped elastic portions, the fixing portion is equipped with a mounting hole, the two arc-shaped elastic portions extend out from the fixing portion, and the tail ends of the arc-shaped elastic portions are mounted in the clamping portion arranged at the back of the keycap. The balancing elastic member can be a balancing spring wound by an elastic metal wire, the fixing portion is a ring portion wound by the middle portion of the elastic metal wire, and the two arc-shaped elastic portions respectively and symmetrically extend from two ends of the ring portion. The key with a balancing device is equipped with the balancing elastic member, every portion of the keycap is enabled to be uniform in stress by pressing the keycap and the key is flexible in action and convenient in use via the balancing elastic member, thereby avoiding problems that the conventional key is inflexible and easy to be locked in action and the like, and reducing the load of the return spring of a switch, and the key is widely adaptable to be compatible with a control cabinet of an industry device, a computer case and the like.
Description
Technical field
The present invention relates to the button that industrial equipment control cubicle, computer housing etc. use, specifically is a kind of button with bascule, and what this button was provided with bascule makes it stressed evenly, and flexible movements can be avoided problems such as conventional keys is stuck.
Background technology
Button is the parts that industrial equipment control cubicle, computer housing etc. generally use, and traditional button is directly installed on the push rod of the switch that is urged mostly, and resetting of button relies on the back-moving spring of switch itself to realize.It is bigger to be that the button of convenient manual operation, particularly control cubicle is done more, and button weight increases, and makes the load increase of the back-moving spring of switch itself, directly influences the useful life of switch; Switch is positioned at the button lower limb simultaneously, and the discontinuity that do not exist together of hand pressing keys end face can cause switch not have function or phenomenons such as feel is bad, card key.
Summary of the invention
In view of the prior art above shortcomings, the invention provides a kind of button with bascule, this button is provided with bascule, and the hand keycap makes its each position stressed evenly by bascule, flexible movements, conventional keys is stuck to avoid, switch does not have problems such as function.
The button that the present invention has bascule is following realization, and it comprises: keycap, and the keycap back side is provided with screens portion; And at least one supports the balance elastic component of keycap, and this balance elastic component has the fixed part of a band installing hole and two from the extended arc elastic part of this fixed part, and the latter end of this arc elastic part is installed on the screens portion at the keycap back side.
Wherein, the balance elastic component is the balancing spring of being reeled and being formed by an elastic metal wire, and its fixed part is the annulus portion of the middle part coiling of elastic metal wire, and two arc elastic parts extend from the two ends symmetry of this annulus portion respectively.
Button of the present invention is provided with the balance elastic component, point presses keycap to make its each position evenly stressed by the balance elastic component, flexible movements, easy to use, phenomenons such as conventional keys action is ineffective, stuck have been avoided, and the load of the back-moving spring of switch own is reduced, be widely used in supporting uses such as industrial equipment control cubicle, computer housing.
Description of drawings
Fig. 1 is the structural representation of exemplary embodiments of the present invention;
Fig. 2 is installed on the state diagram of cabinet for Fig. 1 embodiment;
Fig. 3 is the schematic diagram that Fig. 1 embodiment combines with switch, cabinet.
Embodiment
The present invention is described further below in conjunction with the embodiment accompanying drawing.
As Figure 1-3, the button of embodiment with bascule comprises:
Keycap 2, keycap 2 back sides are provided with switch installation position 22 and screens portion 21, and the screens portion 21 at keycap 2 back sides can be two draw-in grooves, and these two draw-in grooves are positioned at 22 both sides, switch installation position; Among Fig. 1, switch installation position 22 be one from the extended rectangle short column in keycap 2 back sides, be useful on the cavity of jack switch push rod in this rectangle short column, near keycap 2 back sides on one side, the and arranged on left and right sides wall extends left and right reinforcement respectively, the left and right reinforcement outside has small front apron respectively, and the draw-in groove 21 between left and right reinforcement and the adjacent small front apron constitutes screens portion;
And, a balance elastic component that supports keycap, the balancing spring 1 that this balance elastic component has an elastic metal wire to reel and form, annulus portion 12 by the middle part coiling of elastic metal wire is a fixed part, in the middle of the annulus portion is installing hole 13, adopt screw 4 balancing spring can be fixed in cabinet header board 7, extend two arc elastic parts 11 from the two ends symmetry of this annulus portion 12, the latter end of this arc elastic part 11 is installed in the draw-in groove 21 at keycap 2 back sides.
Transparent external key 3 can be set on the keycap 2.Establish the transparent external key 3 of rectangle among the figure on the keycap 2, the transparent external key of this rectangle 3 middle parts are the press section 31 of projection, and there is installing hole 34 at two ends, and the back side, two ends symmetry is extended feet 33, be provided with cavity 32 between two feets 33 and the press section 31, to increase the elasticity of transparent external key.The silk-screen layer can be established in the transparent key key back side, and oil spout.
During installation, the switch fixed head 6 that will have switch 5 is installed on the relevant position of cabinet header board 7, the balancing spring 1 that adopts screw 4 to combine with keycap is fixed on the cabinet header board 7, the push rod of switch 5 is combined with the switch installation position 22 of keycap 2, again 31 back sides, press section and keycap 2 applyings of transparent external key 3 are fixed on the cabinet header board 7, press transparent external key 3 and can make switch 5 actions,, avoid stuck because the balancing spring under the keycap makes its energy producing balanced forces.
Button of the present invention can only comprise keycap 2 and balance elastic component 1, and some button cap 2 makes switch 5 actions, and keycap energy producing balanced forces, and the button of this structure is suitable for need not the occasion use of transparent external key.
When being used for bigger button, because keycap is big, a balance elastic component can be set respectively in the left and right sides of keycap supports keycap, to realize the purpose of producing balanced forces.
That transparent external key 3 on the keycap can adopt is square, circular, ellipse and the transparent external key of polygon, and the normally transparent external key adopts the injection moulding of transparent PC material.
