[0002] A mechanical keyboard is a type of keyboard. Structurally, each key on a mechanical keyboard has a separate switch to control its closure. This switch is also called an "axis."

[0003] The detachable connection between mechanical keyboards and PCB boards has been a popular setting method in recent years. It allows each key of the mechanical keyboard to be unplugged and installed in the user's usual position. However, the plug-in pins of mechanical switches are generally made of soft material and are prone to bending and deformation. Therefore, some mechanical keyboards will be equipped with a large plug-in panel, and the shaft body is plugged and fixed into the hole groove at the corresponding position on the panel. There are clips protruding on both sides of the shaft body. After aligning the shaft body of the key with the hole groove and inserting it, the clip and the top of the shaft body are respectively clipped to the two sides of the panel to complete the installation, which improves the convenience of key fixation.

[0004] The applicant believes that when the side wall of one of the holes in the panel is worn and difficult to fix, the entire panel needs to be replaced. During the replacement, the other keys need to be removed and reassembled, resulting in a lot of physical effort and cost required to repair the mechanical keyboard, thereby increasing the maintenance cost of the entire keyboard.

The side walls of the fixing plate are penetrated by a clamping hole. The clamping pieces on both sides of the shaft body are respectively clamped into the clamping holes of the same pair of fixing plates.

[0008] Preferably, a connecting plate is provided between each pair of the fixing plates, the fixing plates are integrally connected to the connecting plates, and one end of the connecting plate close to the fixing plates is in contact with a side of the PCB away from the shaft.

[0009] Preferably, the clamping member includes a plurality of clamping blocks, and the clamping blocks are provided with inclined guide surfaces along two sides perpendicular to the PCB board, and the two guide surfaces extend toward an end away from the shaft body and approach each other.

[0010] Preferably, the clamping hole is a square hole, and when the clamping block is inserted into the clamping hole, the top walls of all the clamping blocks on one side of the shaft body are tightly pressed against the inner top walls of the corresponding clamping holes.

[0011] Preferably, a limiting plate is provided on the PCB board, and the limiting plate is provided on two opposite sides of the shaft body, and the limiting plate and the fixing plate are respectively in contact with four side walls of the shaft body.

[0022] The following is a further detailed description of three embodiments of the present invention with reference to Figures 1-5.

[0023] Embodiment 1 of the present utility model discloses a key switch installation structure of a mechanical keyboard.

[0024] 1 and 2 , a key switch mounting structure for a mechanical keyboard includes a PCB board 1 and a fixing plate 41 arranged on the bottom wall of a shaft body 3. The fixing plates 41 are provided in multiple pairs, and the multiple pairs of fixing plates 41 are provided corresponding to the number of shaft bodies 3. A clamping member 5 protrudes from two opposite side walls of the shaft body 3, and a plug hole 6 is passed through the PCB board 1. The fixing plate 41 is plugged into the plug hole 6. The side walls of the fixing plate 41 are passed through with a clamping hole 43. The clamping members 5 on both sides of the shaft body 3 are respectively clamped into the clamping holes 43 of the same pair of fixing plates 41.

[0025] When assembling a mechanical keyboard, the fixing plate 41 is inserted into the insertion hole 6, and then the shaft body 3 is aligned with the space between the pair of fixing plates 41 and inserted, so that the clamping parts 5 on both sides of the shaft body 3 are respectively clamped into the clamping holes 43 of the pair of fixing plates 41, thereby clamping and fixing the shaft body 3 on the PCB board 1, making it difficult for the shaft body 3 to separate from the PCB board 1, making it more convenient and quick to install the shaft body 3 on the PCB board 1, and also making it easy to disassemble the shaft body 3. When a shaft body 3 needs to be repaired or replaced, the shaft body 3 is pulled out in a direction away from the PCB board 1, and then the corresponding fixing plate 41 is pulled out, and the shaft body 3 or its corresponding fixing plate 41 can be replaced and repaired. This helps to reduce the situation where a large-area panel is difficult to repair with a single hole slot, greatly reducing the maintenance cost of the mechanical keyboard, and at the same time helps to reduce the situation where the setting of a large-area panel leads to a large number of consumables, thereby increasing the production cost of the mechanical keyboard.

[0026] 2 and 3 , in this embodiment, a connecting plate 42 is provided between each pair of fixing plates 41 , the fixing plates 41 and the connecting plates 42 are integrally connected, and one end of the connecting plate 42 close to the fixing plates 41 is in contact with the side of the PCB board 1 away from the shaft 3 .

[0027] When the fixing plates 41 are plugged into the PCB board 1, the two fixing plates 41 restrict each other through the connecting plate 42, making it difficult for the two fixing plates 41 to be separated from the PCB board 1. At the same time, when installing the fixing plates 41, a pair of fixing plates 41 can be installed at the same time by moving the connecting plate 42, and the connecting plate 42 can limit the height of the snap-in hole 43 after the fixing plate 41 is installed, which is beneficial to improving the convenience of installing the fixing plate 41, reducing the accuracy of aligning the plug-in hole 6 twice, and making the fixing plate 41 easier to install.

[0028] 1 and 2 , in this embodiment, the clamping member 5 includes a plurality of clamping blocks 9 , and the clamping blocks 9 are provided with inclined guide surfaces along both sides perpendicular to the PCB board 1 , and the two guide surfaces extend toward one end away from the shaft body 3 and approach each other.

[0029] The provision of multiple clamping blocks 9 helps to improve the stability of the clamping connection between the clamping member 5 and the clamping hole 43. The multiple clamping blocks 9 can restrain each other, making it difficult for other clamping blocks 9 to separate from the clamping hole 43. The provision of the guide surface makes it easier for the clamping block 9 to be inserted into the clamping hole 43, and the clamping block 9 is not likely to break due to collision with the fixing plate 41.

[0030] 1 and 2 , in this embodiment, the engaging hole 43 is a square hole. When the engaging block 9 is inserted into the engaging hole 43 , the top walls of all engaging blocks 9 on one side of the shaft 3 are tightly pressed against the inner top walls of the corresponding engaging hole 43 .

[0031] The clamping blocks 9 are located at the same height from the PCB board 1, so that multiple clamping blocks 9 can be inserted into the clamping holes 43 at the same time, reducing the resistance encountered during the installation of the shaft body 3 and making the shaft body 3 easier to install.

[0032] 1 and 2 , in this embodiment, the PCB board 1 is electrically connected to the switch socket 3 , and a pin 7 is provided at the bottom end of the shaft body 3 . The pin 7 is plugged into the switch socket 3 to achieve electrical connection between the shaft body 3 and the switch socket 3 . The switch socket 3 and the shaft body 3 are respectively arranged on both sides of the PCB board 1 .

[0033] The provision of the switch socket 3 helps avoid increasing the height of the entire keypad, thereby not affecting the placement or effects of features such as the keyboard lighting. Furthermore, attaching the switch socket 3 to the bottom surface of the PCB board 1 allows the switch socket 3 to be separated from the mechanical switch, helping to prevent frequent changes in the mechanical switch from affecting its stability and making it easier to repair and replace the switch socket 3.

[0034] 1 and 2 , in this embodiment, the connecting plate 42 is provided with an escape groove 44 for the switch socket 3 to be disposed therein, and the switch socket 3 is embedded in the escape groove 44 .

[0035] When installing the fixing plate 41, align the avoidance groove 44 with the switch socket 3 and insert it. The avoidance groove 44 can protect the switch socket 3, and at the same time reduce the situation where the connecting plate 42 covers the side of the switch socket 3 away from the PCB board 1, which causes the thickness of the entire key to increase, making the structure of the entire key more integrated and more integrated, making the switch socket 3 less likely to be damaged.

[0036] Example 2:

[0037] 2 and 4 , in other embodiments, based on embodiment 1, a limiting plate 10 may be further provided on the PCB board 1. The limiting plate 10 is integrally connected to the connecting plate 42. A plug hole is provided on the PCB board 1 for the limiting plate 10 to pass through. The limiting plate 10 is provided on opposite sides of the shaft body 3. The limiting plate 10 and the fixing plate 41 are respectively in contact with the four side walls of the shaft body 3.

[0038] When the fixing plate 41 is clamped to the fixed shaft 3, the limiting plates 10 are arranged on both sides of the shaft 3 where the fixing plates 41 are not set, so that the shaft 3 is difficult to shake between the two limiting plates 10, which is beneficial to limiting the displacement of the shaft 3 from multiple directions, so that the shaft 3 is more firmly installed on the PCB board 1, which is beneficial to improving the working stability of the shaft 3, thereby reducing the possibility of impact wear of the shaft 3, and helping to increase the service life of the mechanical keyboard.

[0039] Example 3:

[0040] 2 and 5 , in other embodiments, based on embodiment 1, a limiting angle 11 may be further provided at at least one pair of diagonal portions of the shaft body 3, the limiting angle 11 being integrally connected to the connecting plate 42, and a plug hole being provided on the PCB board 1 for the limiting angle 11 to pass through, and the limiting angle 11 respectively abuts against two adjacent side walls constituting the top corner of the shaft body 3 where it is located.

[0041] The limiting angle 11 can limit the shaking of the shaft body 3 in the diagonal direction of the shaft body 3, and cooperate with the fixing plate 41 to limit the movement of the shaft body 3, thereby realizing the movement limitation of the shaft body 3 in multiple directions, so that the shaft body 3 is more firmly installed on the PCB board 1, which is beneficial to improving the working stability of the shaft body 3, thereby reducing the possibility of impact wear of the shaft body 3, and helping to increase the service life of the mechanical keyboard.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
