[0002] A computer keyboard is a channel for inputting text control information into a computer, evolving from the keyboard of an English typewriter. When it first appeared on a computer, it was a component of a "teletype machine." The keycaps of a computer keyboard consisted of a middle plate, key cores, and key covers. In ordinary keyboards, a jig was made under the middle plate to support the key cores during assembly to prevent them from falling off.

[0003] The shortcomings of existing technology are: Existing computer keyboard keycaps are inconvenient to clean, removing dust and debris that falls inside the keyboard; separating the keycaps from the key core requires auxiliary tools, making keycap removal laborious and affecting keyboard cleaning efficiency. Therefore, there is a need to provide a computer keyboard keycap and key core structure to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a computer keyboard key core and key cover structure to solve the problems existing in the background art.

A mounting base is fixedly connected to the middle of the top of the inner wall of the key cover, and a mounting assembly is provided at the middle of the top of the inner wall of the mounting base. The mounting assembly includes a base plate, a rotating groove is provided in the middle of the base plate, and a limiting post is fixedly connected to the middle of the rotating groove. A main clamping plate is movably sleeved on the outer wall of the limiting post, and a secondary clamping plate is movably sleeved on the outer wall of the limiting post between the main clamping plate and the secondary clamping plate. A locking post is movably sleeved between the main clamping plate and the secondary clamping plate, and a bolt is fixedly connected to the top of the locking post. The top of the bolt is fixedly connected to the middle of the top of the inner wall of the mounting base.

[0006] Preferably, a tongue depressor is fixedly connected to one side of the outer wall of both the main clamping plate and the auxiliary clamping plate, and a spring is fixedly connected to the bottom end of each of the two tongue depressors. The bottom ends of the two springs are fixedly connected to the top of the base plate near one side.

[0007] Preferably, one end of the main clamping plate and the auxiliary clamping plate are movably sleeved on the limiting post, and both springs are high-strength springs.

[0008] Preferably, the bottom end of the base plate is fixedly connected to the top center of the key shaft, and top plates are fixedly connected to the four corners of the base plate and the bolt. The bolt and the base plate are fixedly connected to the mounting base and the key shaft through the top plates.

[0009] Preferably, the top of the base plate has a structure that is convex in the middle and low on both sides, and the rotation arc of the outer wall of the main clamping plate and the auxiliary clamping plate is adapted to the arc of the top of the base plate.

[0013] 2. This utility model, by providing an installation assembly, allows the key core to move to the top of the key cover. After the key core moves to the top of the key cover, the key shaft in the middle of the key core engages with the mounting base. With the top plate fixed in place, the key cover continues to press downwards, causing the bolts and locking pins at the bottom of the mounting base to move downwards, squeezing the main clamping plate and the secondary clamping plate. Under the action of the pressure plate, spring, and limiting pin, the locking pin moves into the interior of the main clamping plate and the secondary clamping plate. This facilitates the locking pin being engaged between the main clamping plate and the secondary clamping plate under the elastic action of the spring, completing the installation of the key cover and the key core. When disassembly is required, the key cover can be moved upwards, causing the locking pin to move out of the main clamping plate and the secondary clamping plate under the elastic force of the spring, completing the separation of the key cover and the key core. This facilitates quick cleaning of dust inside the keyboard, further improving the keyboard's practicality. Attached Figure Description

A mounting base 3 is fixedly connected to the top center of the inner wall of the key cover 1. A mounting assembly 4 is provided at the top center of the inner wall of the mounting base 3. The mounting assembly 4 includes a base plate 406, with a rotating groove 408 in the center of the base plate 406. A limiting post 409 is fixedly connected to the center of the rotating groove 408. A main clamping plate 407 is movably sleeved on the outer wall of the limiting post 409. A secondary clamping plate 410 is movably sleeved between the main clamping plate 407 and the secondary clamping plate 410. A locking post 403 is movably sleeved between the main clamping plate 407 and the secondary clamping plate 410. A bolt 401 is fixedly connected to the top of the locking post 403. The top of the bolt 401 is fixedly connected to the top center of the inner wall of the mounting base 3. The main clamping plate 407 and the secondary clamping post 403 are connected in series. A pressure plate 404 is fixedly connected to one side of the outer wall of the holding plate 410. A spring 405 is fixedly connected to the bottom end of each of the two pressure plates 404. The bottom ends of the two springs 405 are fixedly connected to the top end of the base plate 406 near one side. One end of the main clamping plate 407 and the auxiliary clamping plate 410 are movably sleeved on the limiting post 409. Both springs 405 are high-strength springs. The bottom end of the base plate 406 is fixedly connected to the middle of the top end of the key shaft 6. Top plates 402 are fixedly connected to the four corners of the base plate 406 and the bolt 401. The bolt 401 and the base plate 406 are fixedly connected to the mounting base 3 and the key shaft 6 through the top plates 402. The top end of the base plate 406 has a structure that is convex in the middle and low on both sides. The rotation arc of the outer wall of the main clamping plate 407 and the auxiliary clamping plate 410 is adapted to the arc of the top end of the base plate 406.

[0022] Specifically, when disassembly is required, the key cover 1 can be moved upwards, causing the locking pin 403 to move out of the main clamping plate 407 and the secondary clamping plate 410 under the elastic force of the spring 405, thus completing the separation of the key cover 1 and the key core 2. This facilitates quick cleaning of the dust inside the keyboard and further improves the keyboard's usability. Specific Implementation Example 2

[0024] Please see Figure 1-3Based on the first specific embodiment, the key cover 1 has a slot 8 at the top of its interior, and the key cover 1 has sliding grooves 7 on all four sides of its inner wall. The key cover 1 has a mounting base 3 fixedly connected to the middle of the top of its inner wall. The key core 2 has a sleeve block 5 fixedly sleeved on its outer wall. The top of the outer wall of the sleeve block 5 is movably engaged with the slot 8, and the four sides of the sleeve block 5 are movably engaged with the sliding grooves 7.

[0025] Specifically: When installing the key cover 1 and the key core 2, in order to facilitate positioning, the key cover 1 moves towards the outer wall of the key core 2. When the outer wall of the key core 2 slides into the slide groove 7 and the slot 8, it positions the key core 2 inside the key cover 1, thereby completing the initial installation of the key cover 1 and the key core 2.

[0026] The working principle of this utility model is as follows: With the sliding groove 7 and the retaining groove 8, during the installation of the key cover 1 and the key core 2, to facilitate positioning, the key cover 1 moves towards the outer wall of the key core 2. When the outer wall of the key core 2 slides into the sliding groove 7 and the retaining groove 8, it positions the key core 2 inside the key cover 1, thus completing the initial installation of the key cover 1 and the key core 2. After the key core 2 moves to the top of the key cover 1, the key shaft 6 in the middle of the key core 2 engages with the mounting base 3. Under the fixed connection of the top plate 402, the key cover 1 continues to be pressed downwards, causing the bolt 401 and the retaining post 403 at the bottom of the mounting base 3 to move downwards, squeezing the main clamp. Under the action of the pressure plate 404, spring 405, and limiting post 409, the holding plate 407 and the auxiliary clamping plate 410 move the locking post 403 into the interior of the main clamping plate 407 and the auxiliary clamping plate 410. Under the elastic action of the spring 405, the locking post 403 is locked between the main clamping plate 407 and the auxiliary clamping plate 410, thus completing the installation of the key cover 1 and the key core 2. When it is necessary to disassemble them, the key cover 1 can be moved upward, and the locking post 403 can be moved out of the main clamping plate 407 and the auxiliary clamping plate 410 under the elastic force of the spring 405, thus completing the disassembly of the key cover 1 and the key core 2.
