Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, combine fig. 2, the utility model discloses a lathe remote control handle, including back lid 1, protecgulum 2, PCB board 3 and

key switch

4, 3 fixed mounting of PCB board are in back lid 1, and the fixed setting of a plurality of key switch 4 matrix arrangements is on

PCB board

3, and 2 fixed lids of protecgulum fit back lid 1 and cover PCB board 3, and a plurality of keyholes 21 have been seted up to 2 upper surface matrix of protecgulum, and keyhole 21 and key switch 4 aim at one by one, still include elastomer 5. The push switch 4 is a straight key switch, and thus has a protruding straight key button with high hardness.

Wherein, elastomer 5 fixed connection is in keyhole 21, and elastomer 5 and key switch 4 closely offset, has enlarged the area that receives the region of pressing, easily presses and has avoided the problem that key switch 4 top punctures the pad pasting.

Specifically, the invention is also realized by the following technical scheme.

Preferably, the elastic body 5 includes a key cap 51 and a plurality of elastic strips 52, the key cap 51 is located in the center of the key hole 21, the key cap 51 is tightly abutted against the key switch 4, one end of the elastic strip 52 is fixedly connected to the side surface of the key cap 51, the other end of the elastic strip 52 is fixedly connected to the hole wall of the key hole 21, and the plurality of elastic strips 52 are circumferentially arranged with the key cap 51 as a circle center. Wherein, the key cap 51 and the elastic strip 52 are both preferably made of rubber materials.

When the elastic body 5 is pressed, the top of the key cap 51 is pressed downwards and pushes the key switch 4 against the bottom of the key cap 51, and in the process, the elastic strip 52 plays a spring-like buffering role.

Furthermore, the end faces of the keycaps 51, which are back to the PCB 3, are flush with each other, so that the film can be tightened when being pasted, the dislocation of the marks on the film can be avoided, and the height of the keycaps 51 can be adjusted by cutting off a part according to the height of the key switch 4.

More specifically, as shown in fig. 1 and in conjunction with fig. 6, the elastic strip 52 includes a bend 521 and a straight strip 522, one end of the bend 521 is fixedly connected to the side surface of the key cap 51, two ends of the straight strip 522 are respectively fixedly connected to the other end of the bend 521 and the wall of the keyhole 21, and the bend 521 extends the extension length of the elastic strip 52 and provides the elastic force.

In addition, as shown in fig. 1, with reference to fig. 3 and 4, a cavity 511 is formed in the keyhole 21 to play a role of buffering, and the problem that the keyhole 21 cannot rebound after being pressed and deformed can be avoided.

As another embodiment, as shown in fig. 1 and in conjunction with fig. 3 and 5, the cavity 511 is through toward one end of the PCB 3, and the top of the key switch 4 is nested in the cavity 511, so as to prevent the key switch 4 and the key cap 51 from being dislocated.

As an optional embodiment, the front cover 2 is further provided with a film sticking region 22 on the upper surface thereof, the key holes 21 are all provided in the film sticking region 22, and the film sticking region 22 is used for sticking a film for identifying the purpose of each key switch 4.

The working principle is as follows:

Compare in current pad pasting handle, this technical scheme can avoid the pad pasting to stab or the pad pasting is difficult to the problem of tight.

Compared with the existing keycap handle, the technical scheme can also avoid the problems that the mark on the keycap is easy to wear and the keycap is easy to break away from the flat surface and lose; in the technical scheme, when the sticking film is punctured or the mark is seriously abraded, only the original film is torn down or a new film is directly stuck on the original film, so that the maintenance is convenient and fast, and the cost is low.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
