Description

A kind of keyboard protection arrangement

Technical field

The utility model is a kind of keyboard protection arrangement.

Background technology

The device keyboard characteristics of manufacturers produce such as now all computing machines, game machine are: keyboard not the time spent cover with dust cover, but when using keyboard, lack any protective device; Each key is arranged closely, and is embedded in one or several grooves.Its drawback is: fall into foreign material, dust in the groove easily; Finger touch each key of easily making dirty; The too frequent key that uses may grind the mistake writing; Not easy to clean; Influence function and attractive in appearance.

Summary of the invention

The purpose of this utility model is a kind of simple in structure, easy to clean, attractive and durable keyboard protection arrangement of design.

The utility model mainly is made up of keyboard casing play, lamina membranacea layer.The keyboard casing play is a hardboard that the protruding hole of front openings is arranged on the position of correspondent button, and the length of side of each side ratio correspondent button in hole is big, so that this casing play covers key is exposed from the hole.The lamina membranacea layer is one the positive not projection of opening on the position of correspondent button, the projection of lamina membranacea layer is entangled the protruding hole of keyboard casing play opening during use, does as a whole covering on the keyboard then.It is noted that each lug must aim at keyboard, easy to use.For fixing this device, can mainly be that the both sides shape is consistent with the keyboard side view with the casing play side, simple and easy hasp perhaps is set is convenient to skeletal fixation.

Casing play is decided with combining by materials used of lamina membranacea layer, perhaps is inserted in connection, perhaps gluing connection, or the connection of alternate manner.

Casing play look convenient for the purpose of, both can be on the lamina membranacea layer, also can be under the lamina membranacea layer.

The casing play recess, promptly the groove place between its sunk key and the key can be made into " Y " type, and casing play is covered on the keyboard regularly, has brought convenience to making.

Casing play can use hard material, as plastic plate; The lamina membranacea layer can use flexible wear-resistant material, as the nylon lamina membranacea.

Casing play and keyboard can be made as one when in particular cases, producing keyboard; The flexible membrane flaggy also can directly be attached on the key when producing keyboard.

Protective device skeleton part of the present utility model also can be other materials such as stainless steel.Its effect is: each key is separately protected respectively; Provide supporting to flexible wear-resistant material; Guarantee that finger can not influence adjacent key when knocking certain key.

Protective device flexible wear-resistant material part of the present utility model can be materials such as plastics, rubber, nylon.Its effect is: cover each key, guarantee simultaneously finger when knocking certain key with do not have protective device to compare hardly can to increase strength; Guarantee that finger does not directly touch symbol on the key when knocking certain key, thereby play the not frayed effect of protected key face cleaning writing.

Protective device flexible wear-resistant material part of the present utility model can be film materials such as plastics, rubber, nylon, and it can reinstatement rapidly after knocking key.

Protective device skeleton of the present utility model and flexible wear-resistant material can be a kind of combinations of material, and such as the processing of thickening or gaining in strength at frame position, the position of key is still flexible wear-resistant material.

Protective device of the present utility model can be used for keyboard, is mainly used in the keyboard of robot calculator, electronic game machine, bank cipher input equipment etc.

Skeleton portion is divided into the needs that increase attractive in appearance or suitable individual character, can be colored, also can increase pattern, and the vacant part outside the key can increase other complementary parts, but can not influence the use of key.Certainly, these colors, pattern and other complementary parts can certainly not added up.

Flexible wear-resistant material is general select transparent, as opaque can material positive attached in addition its cover below character on institute's corresponding keys.Flexible wear-resistant material can be made as and the same big integral body of keyboard, and the smaller projection of correspondent button is arranged on the position of each key, the projection that guarantees projection and skeleton corresponding keys be locked and key and key between when knocking, be independent of each other; These can be by mould production.Also can make the cover more smaller than correspondent button respectively to each key, direct and skeleton corresponding keys is nested together.If can not influence other key in the time of can guaranteeing to knock certain key, cover also can be bigger than correspondent button.A kind of special circumstances are, whole keyboard can only not have the flexible material of projection yet with one or several sheets, but this material should be able to bring into play the description of contents part the effect of book.When another kind of special circumstances are production flexible wear-resistant material directly is attached on the key face.

Protective device of the present utility model; constitute an integral body by the lamina membranacea layer that covers flexible wear-resistant material on a complete casing play and each key; can cover on keyboard always; avoid dust foreign material etc. to fall in the groove; avoid finger directly to contact, thereby protected the cleaning of keyboard and attractive in appearance with keyboard.This apparatus structure is simple, and cost is low, and is easy to clean, can protect keyboard effectively.When using keyboard such as uncomfortablely use protective device of the present utility model, can certainly, this moment, the utility model can be brought into play the effect of a general keyboard dust cover.
