Abstract
The utility model relates to a key cover for an electric appliance with an operation key. The corresponding position of a keyboard face cover and the operation key is provided with a convex operation key cap, and the operation key cap with a shape matched with the shape of the operation key is sheathed on the operation key. The utility model has the advantages of good wear resistant performance, good tear resistant performance, good rebound elasticity, no linking interference among the key caps and no influence to the keyboard operation and can be covered on a keyboard for a long term.
Description
The utility model relates to a kind of key cover with operating key electrical equipment.
The electric equipment products that have keyboard or key button at present are more and more many, as: computing machine, typewriter, learning machine, counter, various telephone set, game machine etc.Because this electric appliances is generally accurate, and keyboard or key button operation are more frequent, so require it should have dustproof, moistureproof, the wear-resisting multiple performances such as preventing bacterial cross-infection that undermines.Existing key cover generally is that the cover made from cloth or fiber and other material when electrical equipment is idle covers appliance keypads, then it must be removed during use.Use inconvenience, and since electrical equipment in use dust, foreign matter is easier falls in the machine, so it does not have good protective effect.Finger directly touches operating key, the easy to wear or damage of long period of operation keyboard.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of wear-resisting, and anti tear and rebound resilience are good, and no interlock disturbs between each keycap, can cover in for a long time on the keyboard, operation is not had the key cover of the band operating key electrical equipment of influence.
The purpose of this utility model can reach by following measure:
A kind of key cover with operating key electrical equipment, it comprises the keyboard face shield, and its special character is: this keyboard face shield and the corresponding position of operating key are provided with convex operation keycap, and the operating key cap sleeve that matches with the operating key shape is on operating key.
Can have a gap between operation keycap of the present utility model and operating key.
Groove between operation keycap of the present utility model is good with the arc-shaped transition link slot.
Keyboard face shield of the present utility model is good with elastic apparent material.
The edge of keyboard face shield of the present utility model can be provided with fixed band.
The accompanying drawing drawing is described as follows:
Fig. 1 is the cut-open view of the utility model computer key cover embodiment;
Fig. 2-3 is the structural representation of the utility model counter and telephone key cover.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, keyboard face shield 2 of the present utility model covers on the keyboard of band operating key 6 electrical equipment.Be provided with operation keycap 3 with each corresponding face shield 2 in operating key 6 positions.Shape and each operating key 6 shapes of operation keycap 3 match, but contact matching between keycap 3 and the operating key 6, but to have a gap 4 for good.The link slot 5 that adjacent keycap is 3 is good to adopt the arc-shaped transition link slot, and this structure can make keycap 3 have better rebound resilience.When being used on the normal electrical equipment that moves, fixed band 1 can be set at its edge, it is good having certain flexible material with employing.Face shield 2 moved when fixed band 1 can prevent that electrical equipment from moving.The utility model can adopt rubber, plastics, latex elastomeric material, but with high-elastic resin, amino resins be Main Ingredients and Appearance high molecule alloy material through and the material made with modification.Production technology can adopt vacuum mo(u)lding technology.
Fig. 2-3 is respectively the structural representation of the utility model counter key cover and telephone key cover.
The utility model compared with prior art has following advantage:
1, the utility model material softness and high resilience, and be transparent material, use no any to operation Impact so can cover in for a long time on the keyboard, all can get keyboard under off working state, especially duty To protection;
2, feel comfortable, can avoid the operator to produce pathology because pointing long-term touching;
3, available buffer key force is avoided the operated key surface abrasion, prolongs button service life;
4, wear-resisting and tear-resistant performance is good, long service life;
5, use and clear Xian Jun are more convenient, can realize that key cover individual is special-purpose;
6, keycap and operated key shape match, and it is separately independent that each operates keycap, and activity freely, and is mutual Not having any interlock disturbs;
7, have certain degree of hardness, rebound resilience is good;
8, can prevent reliably that dust or foreign matter from falling in the machine from the operating key slit, electron device can obtain reliable protection in the machine.Especially being suitable for particular surroundingss such as chemical industry, field uses.
