[0028] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0029] See also Figure 1-2 The present invention provides a keypad fixing device in which the keypad 10 does not need to be fixed by fasteners, and installation and removal are very convenient and quick. In order to achieve the above technical objectives, the keypad fixing device includes a keypad 10 and a key panel 20. The specific structure is described as follows:

[0030] The keypad 10 can be specifically a PC keypad. A limiting hole 11 is provided on the keypad 10. The limiting hole 11 is used to limit the position of the keypad 10 and also serves as a positioning and guiding function. The limiting hole 11 can accurately guide the keypad 10 to be installed in a defined position, thereby improving the accuracy of the installation position of the keypad 10. The limiting hole 11 can be multiple in number, and the limiting hole 11 can be specifically located in the outer edge area of ​​the keypad 10 to avoid occupying the central area of ​​the keypad 10.

[0031] The key panel 20 is provided with a positioning member 21, a first engaging member 22 and a second engaging member 23. The positioning members 21 correspond to the limiting holes 11, that is, the number of the positioning members 21 is the same as the limiting holes 11, and the position of each positioning member 21 corresponds to the position of each limiting hole 11.

[0032] The first engaging member 22 and the second engaging member 23 are spaced apart on the key panel 20 . Specifically, the first engaging member 22 and the second engaging member 23 are spaced apart on both sides of the key panel 20 to avoid occupying the middle area of ​​the key panel 20 .

[0033] The positioning member 21 can be removably embedded in the limiting hole 11; the size of the positioning member 21 matches the size of the limiting hole 11 (for example, the size of the positioning member 21 is the same as the limiting hole 11, or the size of the positioning member 21 is slightly smaller than the limiting hole 11, or the size of the positioning member 21 gradually increases from top to bottom, the upper end size of the positioning member 21 is smaller than the limiting hole 11, and the lower end size of the positioning member 21 is larger than the limiting hole 11), so that the positioning member 21 can be removably embedded in the limiting hole 11.

[0034] When the positioning member 21 is inserted into the limiting hole 11, the first engaging member 22 and the second engaging member 23 are respectively engaged with the two sides of the key plate 10, thereby reliably fixing the key plate 10. It is understood that after the key plate 10 is mounted on the key panel 20, the key plate 10 and the key panel 20 are electrically connected, for example, by conductive pins, which is not specifically limited in the present invention.

[0035] In the technical solution of the present invention, a limiting hole 11 is provided on the key plate 10; a positioning member 21, a first engaging member 22 and a second engaging member 23 are provided on the key panel 20, and the first engaging member 22 and the second engaging member 23 are arranged at intervals on the key panel 20, and the positioning member 21 is detachably embedded in the limiting hole 11; when the positioning member 21 is embedded in the limiting hole 11, the first engaging member 22 and the second engaging member 23 are respectively engaged with the two sides of the key plate 10; thus, by aligning the limiting hole 11 with the positioning member 21, the key plate 10 can be pressed to make the positioning member 21 embedded in the limiting hole 11, and the first engaging member 22 and the second engaging member 23 are respectively engaged with the two sides of the key plate 10, thereby realizing the installation and fixation of the key plate 10, which is simple, convenient and fast to operate, and is also easy to disassemble.

[0036] Furthermore, in some embodiments, such as the present embodiment, the positioning member 21 includes a positioning post 211 and a limiting seat 212. The positioning post 211 is disposed on the limiting seat 212 and protrudes from the limiting seat 212. The positioning post 211 is configured to be embedded in the limiting hole 11. The limiting seat 212 is larger than the limiting hole 11 and is configured to limit the installation position of the keypad 10.

[0037] Specifically, the limiting seat 212 includes two limiting blocks 213, which are arranged at an angle on either side of the positioning column 211. For example, the two limiting blocks 213 are perpendicular to each other. The two limiting blocks 213 can improve the stability of the positioning column 211 and reliably limit the keypad 10.

[0038] Furthermore, in some embodiments, such as the present embodiment, there are multiple limiting holes 11, and the multiple limiting holes 11 are evenly arranged on the periphery of the key plate 10. For example, in the present embodiment, there are four limiting holes 11, and the four limiting holes 11 are respectively arranged at the four corners of the key plate 10.

[0039] Correspondingly, the number of the positioning members 21 is the same as the number of the limiting holes 11, and the plurality of positioning members 21 are embedded in the plurality of limiting holes 11 in a one-to-one correspondence. For example, in this embodiment, the number of the positioning members 21 is four, and the positions of the four positioning members 21 correspond to the positions of the four limiting holes 11 in a one-to-one correspondence, and the positioning posts 211 of the four positioning members 21 are embedded in the four limiting holes 11 in a one-to-one correspondence.

[0040] Furthermore, the first engaging member 22 includes a first hook 221. When the positioning member 21 is inserted into the limiting hole 11, the first hook 221 hooks onto the side of the keypad 10. The hook portion of the first hook 221 faces the inner side of the keypad 10. The first hook 221 has a certain degree of elasticity and can be deformed so that the side of the keypad 10 can be snapped into the first hook 221.

[0041] Furthermore, to enhance the strength of the first hook 221, the first engaging member 22 further includes a first reinforcing plate 222, which is disposed on the back side of the first hook 221 and supported on the key panel 20. The first reinforcing plate 222 can be integrally formed with the first hook 221, and the number of first reinforcing plates 222 can be multiple. For example, in this embodiment, there are two first reinforcing plates 222, one located on either side of the first hook 221.

[0042] Furthermore, the second engaging member 23 includes a second hook 231. When the positioning member 21 is inserted into the limiting hole 11, the second hook 231 hooks the side of the keypad 10. The hook portion of the second hook 231 is oriented toward the inside of the keypad 10. The second hook 231 has a certain degree of elasticity and can be deformed so that the side of the keypad 10 can be snapped into the second hook 231.

[0043] Furthermore, to enhance the strength of the second hook 231, the second engaging member 23 further includes a second reinforcing plate 232, which is disposed on the back side of the second hook 231 and supported on the key panel 20. The second reinforcing plate 232 can be integrally formed with the second hook 231, and the number of second reinforcing plates 232 can be multiple. For example, in this embodiment, there are two second reinforcing plates 232, one located on either side of the second hook 231.
