Abstract
The utility model relates to keyboard push-button, in particular to a cross supporter key cap anti-falling-off mechanism which effectively prevents the key cap from disengagement, and has the advantages of loosening proof, low noise, comfortable handfeel, good reliability and simple structure. The cross supporter key cap anti-falling-off mechanism comprises an arm support and a key cap 1 supported and matched by the arm support, and is characterized in that the mechanism still consists a rabbet fastener 2 and a self-lock fastener 3 arranged on the inner surface of key cap 1, corresponding and matched with the arm support with the self-lock fastener 3 in the shape of a hook; a spacing boss 4 is arranged in front of the self-lock fastener 3. The key cap of the utility model can not get loosened and disengaged. So can not the key cap, even though the keyboard is subjected to greater vibration; the utility model has the advantages of comfortable handfeel, low noise, good reliability, simple structure, easy implementation and high adaptability.
Description
Technical field
The utility model relates to keyboard, specifically, relates to and can prevent effectively that keycap from coming off, and has the function anti-loosening, that noise is little simultaneously, and comfortable feel, good reliability, arm support keycap escapement simple in structure.
Background technology
The version that the current keyboard of notebook computer or the press-key structure of other miniature ultra-thin keyboard generally adopt arm support formula supporting construction to cooperate with keycap, not only can reduce the effective thickness of existing keyboard to greatest extent, the volume and the quality of keyboard have also been reduced simultaneously effectively, and, make installation, use and carry and seem more convenient, thereby, be subjected to the generally approval and the favor in market.But because the joining place of the inner surface of its keycap and supporting construction adopts the elasticity extruding position limiting structure of symmetry card post, in use, because of the gap increase is easy to generate loosening, can cause bigger noise simultaneously, make feel also undesirable, moreover if this keyboard is when being subjected to bigger vibrations, its keycap also can come off along the joining place of itself and supporting construction.Therefore, along with the continuous progress of science and technology and the continual renovation of product are regenerated, existing arm support formula button is still waiting further to improve and innovation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of arm support keycap escapement, can prevent effectively that keycap from becoming flexible, coming off, and improving the reliability of its use, and reduces noise, strengthens the feel of its use.
Technical problem of the present utility model realizes by following technical scheme: construct a kind of arm support keycap escapement, comprise arm support and support and the keycap that cooperates, it is characterized in that, also comprise and be arranged at described keycap inner surface and and the tenon buckle that cooperate and self-locking buckle corresponding with described arm support, described self-locking buckle is hook-shaped, and is provided with positive stop lug boss in its place ahead.
Arm support keycap escapement according to the utility model provides is characterized in that the degree of depth of described self-locking buckle is greater than the cross bar radius of turn of described arm support correspondence.
Arm support keycap escapement according to the utility model provides is characterized in that, described self-locking buckle is two of symmetry, and described positive stop lug boss is arranged at the place ahead, middle part between described two self-locking buckles.
Realize arm support keycap escapement of the present utility model, have following advantage: phenomenon loosening and that come off can not take place in keycap, even keyboard also is like this when being subjected to bigger vibrations, comfortable feel, noise is little, good reliability, simple in structure, to implement easily, applicability is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model keycap;
Fig. 2 is the longitudinal sectional drawing of the utility model keycap along the self-locking buckle.
Embodiment
Arm support keycap escapement as shown in Figure 1 and Figure 2, comprise arm support and support and the keycap 1 that cooperates, also comprise and be arranged at keycap 1 inner surface and and the tenon buckle 2 that cooperate and self-locking buckle 3 corresponding with arm support, self-locking buckle 3 is hook-shaped, and is provided with positive stop lug boss 4 in its place ahead.The degree of depth of self-locking buckle 3 is greater than the cross bar radius of turn of arm support correspondence.Self-locking buckle 3 is two of symmetry, and positive stop lug boss 4 is arranged at two the place aheads, middle part between the self-locking buckle.
Arm support keycap escapement of the present utility model, hook-shaped self-locking buckle 3 is set, cooperate with the positive stop lug boss 4 and the tenon buckle 2 in its place ahead, make arm support be self-locking state, and pin down mutually and retrain, make keycap 1 that phenomenon loosening and that come off can not take place, and strengthened feel, reduced noise.
