Description

The quick detachable mechanical keyboard of keycap

Technical field

The present invention relates to a kind of mechanical keyboard structure, particularly relate to the quick detachable mechanical keyboard of a kind of keycap.

Background technology

Now thin film type keyboard is used very extensively, and relatively and thin film type keyboard, although the mechanical keyboard price is more expensive, mechanical keyboard has good hand touch, can handling height, and the advantage such as sensitive and durable.Because each button is to be triggered by an axle, therefore separately independently, so if problem has occured in certain button, as long as the axle of button is just changed and can normally be used.And the contact of thin film type keyboard and circuit, all on film, so as long as film goes wrong, just can only again change.

Because present mechanical keyboard all uses special design, need to keycap be taken out from axle with key puller, then cleans or change the work of axle, operation is not very convenient like this.

Summary of the invention

The technical issues that need to address of the present invention provide a kind of key puller that need not, keycap just can easy removal the mechanical keyboard of assembling.

For solving above-mentioned technical problem, the quick detachable mechanical keyboard of keycap of the present invention comprises keycap, axle and pcb board, the axle lower end has outstanding conductive junction point to link to each other with pcb board, conductive junction point is with volute spring outward, the outer serum cap that is with of volute spring, the lower end of serum cap is connected on the pcb board, and the upper end of axle is connected on the chassis, and the axle upper end is passed the chassis and is connected with keycap; Described axle is cylinder, and the link of axle and keycap has screw thread; Described keycap inner hollow, there is inside protuberance at the middle part, have on the protuberance with axle on the screw that adapts of screw thread.

After adopting such structure, can easily keycap be screwed on the axle, when needs clean keycap or again change axle, as long as keycap is screwed out.Keycap can be screwed on again after having carried out required work, whole like this mechanical keyboard can be more durable, and is more attractive in appearance.

Description of drawings

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of the quick detachable mechanical keyboard of keycap of the present invention.

Fig. 2 is the keycap vertical view of the quick detachable mechanical keyboard of keycap of the present invention.

Fig. 3 is the key arrangement schematic diagram of the quick detachable mechanical keyboard of keycap of the present invention.

Among the figure: 1 is keycap, and 2 is screw thread, and 3 is axle, and 4 is bracing ring, and 5 is the chassis, and 6 is volute spring, and 7 is pcb board, and 8 is serum cap, and 9 is netted screw thread

Embodiment

The easily detachable mechanical keyboard of keycap as shown in Figure 1, comprise keycap 1, axle 3 and pcb board 7, axle 3 lower ends have outstanding conductive junction point to link to each other with pcb board 7, conductive junction point is withvolute spring 6 outward, the outer serum cap 8 that is with ofvolute spring 6, the lower end of serum cap 8 is connected on the pcb board 7, and the upper end of axle 3 is connected on thechassis 5, and axle 3 upper ends are passedchassis 5 and are connected with keycap 1; Described axle 3 is cylinder, and axle 3 hasscrew thread 2 with the link of keycap 1; Described keycap 1 inner hollow, there is inside protuberance at the middle part, have on the protuberance with axle on the screw that adapts of screw thread.Like this can be easily with keycap 1 spinning in and out, it is very firm that keycap 1 also can be fixed.If keycap 1 is cleaned or fault has appearred in button axle 3, keycap 1 can be screwed out, clean or change axle 3 to keycap 1.The position that axle 3 passeschassis 5 is useful on spacingrubber circle 4 all around, can better limit like this axle 3 except other axial directions motions, so that button is more sturdy and durable.

Keycap 1 as shown in Figure 2 is round table-like, the netted screw thread 9 that increases frictional force is arranged around the round platform keycap 1, and such keycap 1 has certain gradient from top to bottom, can pin the position of the gradient in the time of back-out, because netted screw thread 9 has increased frictional force, can easily keycap 1 be screwed out; What also can revolve when keycap 1 is screwed on is very fastening.

Keycap 1 as shown in Figure 3 becomes to be staggered at keyboard, has so both seemed compact, has reduced the space that button takies, and seems again attractive in appearance.Operate also more convenient, can well remember each button residing position on keyboard.Keycap is made by the POM plastics, because the POM plastics are thermoplastic engineering plastics of high density, high-crystallinity, have good physics, machinery and chemical property, excellent crocking resistance is especially arranged, so still can keep good performance through long-term friction, the feel that touches so that the user feels custom, uses comfortable.

Certainly, the material of keycap 1 can be other applicable materials, for example: ABSplastic.Rubber circle 4 and keycap 1 also can be other applicable shapes.Such conversion all drops within the scope of protection of the invention.

Claims (5)
