[0002] With the optimization and popularization of computers, keyboards, as a command and data input device for operating computer operations, are also being updated with technological changes. Keyboards are the most commonly used and most important input device. English letters, numbers, punctuation marks, etc. can be input into the computer through the keyboard, thereby issuing commands to the computer, inputting data, etc. According to the working principle of the keyboard, it can be divided into plastic film keyboards, conductive rubber keyboards and mechanical keyboards; structurally, each key of a mechanical keyboard has a separate switch to control the closure. This switch is also called an "axis". According to the classification of micro switches, mechanical keyboards can be divided into traditional tea axes, green axes, white axes, black axes, red axes and optical axes.
[0003] As mechanical keyboards have a strong sense of paragraphing, they will cause a lot of noise during use, which is particularly unsuitable for use in office environments. Currently, many mechanical keyboards simply use rubber rings to buffer and reduce noise, but the noise reduction effect is relatively poor. In this regard, this solution specifically proposes a mechanical keyboard with a silencer structure to solve the above problem. Utility Model Content

[0024] Example: Figure 1 — Figure 4As shown: it includes a mechanical keyboard body 1, a keycap body 2, a base body 3 and a muffler block 4. The top of the mechanical keyboard body 1 is movably provided with a plurality of keycap bodies 2 of different sizes to realize intelligent input. The mechanical keyboard body 1 is provided with a base body 3 on one side of the bottom of the keycap body 2. The base body 3 is a trapezoidal structure with a large internal space and a small bottom space. A fixing plate 31 is fixedly installed around the inside of the base body 3. A fixing groove 32 is opened at the center of the top of the fixing plate 31. A fixing rod 33 is fixedly installed at the center of both ends of the fixing groove 32 on the fixing plate 31. The fixing rods 33 are connected through the fixing rods 33. The silencer block 4 is used to buffer and reduce noise from the knocking of the keycap body when it descends. Buffer springs 41 are fixedly installed at the centers of both ends of the silencer block 4, and the other ends of the buffer springs 41 are fixedly installed on the fixing plates 31 to achieve a buffering effect. A hole 34 is opened at the center of the top of the base body 3, and a keycap connecting column 21 is movable through the hole 34 to achieve keyboard knocking. The keycap connecting column 21 is bonded and fixed to the limiting block 22 at the surrounding parts of the interior of the base body 3. The surrounding parts of the limiting block 22 and the top of the silencer block 4 are rotatably connected with a hinge rod 24 through a hinge 23. The rotatable connection allows the keycap body to buffer and silence noise at multiple angles.
[0025] See also Figure 3 and Figure 4 The buffer spring 41 is movable and runs through the periphery of the fixing rod 33, and is movable through the fixing rod 33. The structure is simple and stable. The top of the key cap connecting column 21 is fixed at the bottom center of the key cap body 2. A buffer ring 25 is arranged on the key cap connecting column 21 at one side of the bottom of the key cap body 2. An arc-shaped air bag 26 is fixedly installed around the bottom of the buffer ring 25. A rubber pad 35 is bonded and fixed at the periphery of the hole 34 on the top of the base body 3. The buffer ring 25 is movable at the top center of the rubber pad 35. A good sound-absorbing effect is achieved between the arc-shaped air bag under the buffer ring and the rubber pad. The structure is simple. Buffer pads 42 made of rubber are fixedly installed at both ends of the sound-absorbing block 4, and the buffer pads 42 are movable in the fixing groove 32. The hinged rods 24 are symmetrically movable at the top around the inner part of the base body 3. A non-slip pad 27 made of rubber is bonded and fixed on one side of the top of the key cap body 2, which is easy to use, increases friction performance, and improves stability.
[0026] When in use, the mechanical keyboard can be used stably through the keycap body of the mechanical keyboard body, and the structure is simple and stable. During the process of the keycap body sinking due to tapping, the limit block, hinge and hinge rod under the keycap connecting column push the silencer block in the fixed groove, and the silencer block achieves the effect of buffering and noise reduction under the action of the fixed rod, buffer spring and buffer pad. The structure is simple and stable, and the design is ingenious. At the same time, the buffer ring on the keycap connecting column and the rubber pad are used for buffering and offsetting to eliminate noise. The arc-shaped air bag increases the silencer effect, and the practical performance is strong.
