[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In use, the user inserts the limiting fixing plate into one end of the mounting groove. When one side of the limiting fixing plate is close to one end of the keyboard, the positioning block inserts into the positioning groove, establishing a positioning connection between the limiting fixing plate and the keyboard. Simultaneously, the limiting protrusion, driven by a spring, enters the fixing groove, securing the limiting fixing plate and the keyboard. This facilitates the installation and fixation of the keyboard. When disassembly is required, the user presses the pressing protrusion in the rectangular hole with their thumb, causing the moving rod to overcome the spring force. This allows the moving rod to move the limiting protrusion, causing it to simultaneously exit the fixing groove, thus releasing the restriction on the limiting fixing plate and facilitating the disassembly of the limiting fixing plate and the keyboard. This device, through the cooperation of the limiting fixing plate, the positioning connection mechanism, and the fixing mechanism, enables quick assembly and disassembly of the keyboard, improving operational efficiency and enhancing the overall aesthetics after installation.

When the keyboard 3 is installed in place inside the mounting groove 2, the plug can be connected to the USB connection socket, thus facilitating the normal use of the keyboard 3. The sealing gasket 9 is made of waterproof and dustproof rubber material, which can improve the sealing effect of the gap between the mounting groove 2 and the keyboard 3.

[0022] Furthermore, a limiting plate 4 is provided inside the mounting groove 2 at one end of the keyboard 3. Two positioning posts 7 are fixedly installed at the end of the keyboard 3 away from the limiting plate 4. Two positioning holes 8 corresponding to the positioning posts 7 are opened on the inner side wall of the mounting groove 2. The positioning posts 7 are inserted into the positioning holes 8. With the positioning posts 7 and positioning holes 8, the keyboard 3 is easily positioned and installed inside the mounting groove 2, which improves convenience and minimizes the possibility of deviation during the installation of the keyboard 3.

[0023] Furthermore, a positioning connection mechanism 5 connected to the keyboard 3 is provided on one side of the limiting fixing plate 4. The positioning connection mechanism 5 includes a positioning groove 501 and a positioning block 502. Two positioning grooves 501 are opened on the side of the keyboard 3 near the limiting fixing plate 4, and two positioning blocks 502 are fixedly installed on the side of the limiting fixing plate 4 near the keyboard 3. The positioning blocks 502 are inserted into the inside of the positioning grooves 501. Through the cooperation between the positioning blocks 502 and the positioning grooves 501, the keyboard 3 can be positioned and fixed, which can ensure that the keyboard 3 will not loosen due to external force shaking during use.

[0024] Furthermore, the limiting and fixing plate 4 is internally provided with a fixing mechanism 6 connected to the mounting groove 2. The fixing mechanism 6 includes a protruding plate 601, a moving rod 602, a limiting protrusion 603, a spring 604, a fixing groove 605, and a rectangular hole 606. Two protruding plates 601 are fixedly installed on the inner bottom surface of the limiting and fixing plate 4, and a moving rod 602 is movably passed through one side of each of the two protruding plates 601. A limiting protrusion 603 is fixedly installed at one end of the moving rod 602, and the end of the limiting protrusion 603 away from the moving rod 602 extends to the outside of the limiting and fixing plate 4. A spring 604 is provided on the outer surface of the moving rod 602, and one end of the spring 604 is fixed to one side of the protruding plate 601. The other end of 604 is fixed to one side of the limiting protrusion 603. The inner wall of the mounting groove 2 is symmetrically provided with fixing grooves 605 corresponding to the limiting protrusion 603. The limiting protrusion 603 is inserted into the fixing groove 605. The end of the limiting protrusion 603 away from the moving rod 602 is provided with an arc-shaped transition surface. The spring 604 facilitates the T-shaped limiting protrusion 603 to reset. This ensures that one end of the limiting protrusion 603 is always inserted into the fixing groove 605, maintaining the fixation of the limiting fixing plate 4, thereby achieving the limiting fixation of the keyboard 3. The arc-shaped transition surface at one end of the limiting protrusion 603 improves the ease of installation of the limiting fixing plate 4.

[0025] Furthermore, a rectangular hole 606 is provided on the top surface of the limiting fixing plate 4. One end of the moving rod 602 away from the limiting protrusion 603 extends into the interior of the rectangular hole 606. A pressing protrusion is fixedly installed at the top end of the moving rod 602 extending into the rectangular hole 606. The rectangular hole 606 facilitates the extension of one end of the moving rod 602 into its interior. When personnel need to disassemble the keyboard 3, they can first press the protrusion, causing the pressing protrusion to drive the moving rod 602 to move. This facilitates the disassembly of the limiting protrusion 603 from the interior of the fixing groove 605, thereby facilitating the release of the restriction on the limiting fixing plate 4 and the disassembly of the limiting fixing plate 4 and the keyboard 3.

[0026] The implementation principle of this utility model's quick-release keyboard for portable laptops is as follows: When the user needs to install the keyboard 3, first insert the keyboard 3 into one end of the mounting groove 2. After the keyboard 3 is fully inserted into the mounting groove 2, the positioning pin 7 will insert into the positioning hole 8, and the SUB plug on one side of the keyboard 3 will connect to the USB socket provided inside the mounting groove 2, thus facilitating the normal use of the keyboard 3. After the keyboard 3 is positioned and installed, the user then inserts the limiting fixing plate 4 into one end of the mounting groove 2. When one side of the limiting fixing plate 4 is close to one end of the keyboard 3, the positioning block 502 inserts... The positioning plate 4 and the keyboard 3 are positioned and connected inside the positioning groove 501. At the same time, when the positioning plate 4 is inserted into the mounting groove 2, the arc-shaped transition surface of one end of the positioning protrusion 603 will contact the side of the mounting groove 2, so that the positioning protrusion 603 will retract into the positioning plate 4 under the action of the extrusion force. When the positioning plate 4 and the keyboard 3 are positioned and connected, the positioning protrusion 603 corresponds to the fixing groove 605. This makes it easy for the positioning protrusion 603 to enter the fixing groove 605 under the action of the spring 604, thereby fixing the positioning plate 4 and the keyboard 3. This makes it easy to install and fix the keyboard 3.

[0027] When disassembly is required, the thumb of one hand presses the pressing protrusion in the rectangular hole 606, which drives the moving rod 602 to overcome the spring force. This makes it easy for the moving rod 602 to drive the limiting protrusion 603 to move, so that the limiting protrusion 603 exits the interior of the fixing groove 605 at the same time, which makes it easy to release the restriction on the limiting fixing plate 4. This facilitates the disassembly of the limiting fixing plate 4 and the keyboard 3, improving efficiency. Through the cooperation of the limiting fixing plate 4, the positioning connecting mechanism 5 and the fixing mechanism 6, this device can realize the quick disassembly and assembly of the keyboard 3, improve the operating efficiency, and enhance the overall aesthetics after installation.
