Description

Technical Field

[0001] The invention relates to the technical field of mechanical keyboards, in particular to a mechanical keyboard axis tester. Background Art

[0002] Mechanical keyboards are high-end keyboard products that are popular among many computer users and gamers. However, there are many types of mechanical keyboard key switches. Before purchasing a mechanical keyboard, users are often confused about the key switch pressure, feedback strength, sound volume, and basic structure. They often blindly refer to the keyboard reviews and buy blindly, which greatly consumes their budget.

[0003] In view of the above situation, mechanical keyboard axis testers came into being. A mechanical keyboard axis tester is a small trial keyboard that assembles a single axis or several keys with different axes on a miniature base. The price is much lower than that of a complete mechanical keyboard. Users can intuitively feel whether the key axis meets their needs by performing dozens or hundreds of key operations on the mechanical keyboard axis tester, so that they can finally purchase the corresponding mechanical keyboard.

[0004] The applicant has found in practice that in order to prevent the key shaft from accidentally falling off, the existing mechanical keyboard shaft tester needs to twist or weld the shaft foot of the key shaft, so that the base and the key become a solidified one-piece product, and other types of key shafts cannot be replaced; furthermore, in the existing mechanical keyboard shaft tester, the base often does not have a battery compartment, or the arrangement is unreasonable, which makes disassembly and assembly difficult and the battery power supply unstable.

[0005] Therefore, it is necessary to propose a new improvement plan for the mechanical keyboard axis tester. Summary of the invention

[0006] The present invention aims to provide a mechanical keyboard axis tester, and its technical solution is as follows.

[0007] A mechanical keyboard shaft tester comprises a base and a keyboard key, wherein the keyboard key comprises a shaft body mounted on the base and a key cap mounted on the shaft body;

[0008] The top surface of the base forms a groove-shaped cavity, a circuit board is arranged inside the cavity, an axle seat is installed in the circuit board, the axle seat has an electrode jack exposed from the top of the circuit board, and a battery compartment is installed on the bottom surface of the circuit board, and a detachable button battery is arranged in the battery compartment;

[0009] The base is provided with a removable upper cover in the groove of the cavity. The middle part of the upper cover has a window for accommodating the shaft body. The inner edge of the window forms an inner wall with height. The inner wall forms a snap-fitting notch for the shaft body. The bottom end of the upper cover forms a rib, which just presses the circuit board downward to fit tightly into the cavity.

[0010] Furthermore, a clamping groove is formed on the inner wall of the notch of the cavity, and a clamping block that is buckled with the clamping groove is formed on the outer periphery of the upper cover.

[0011] Furthermore, the lower edge of the clamping block is chamfered.

[0012] Furthermore, a light emitting unit is provided on the top of the circuit board.

[0013] Furthermore, the light-emitting unit is an RGB lamp bead.

[0014] Furthermore, the circuit board includes a lower PCB board and an upper PCB board arranged parallel to the lower PCB board. The top surface of the lower PCB board is provided with conductive pins on both sides. The lower ends of the conductive pins are welded to the lower PCB board, and the upper ends of the conductive pins are welded to the upper PCB board. The lower PCB board and the upper PCB board are electrically connected through the conductive pins. The battery compartment is arranged on the bottom surface of the lower PCB board, the shaft seat is arranged on the top surface of the lower PCB, and the upper PCB board is provided with through holes corresponding to the electrode jacks.

[0015] Furthermore, the lower end of the shaft seat abuts against the lower PCB board, and the upper end of the shaft seat abuts against the upper PCB board.

[0016] Furthermore, a sound generating unit is provided in the circuit board.

[0017] Furthermore, the sound-generating unit is a buzzer or a speaker.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The window of the upper cover cooperates with the key shaft of the keyboard key so that the key shaft will not be distorted due to force;

[0020] (2) The key shaft body is hot-swappable through the shaft seat, making it easy to replace the key shaft body;

[0021] (3) The unstable battery problem is solved by using the battery compartment.
