[0002] A wireless keyboard needs to interact with a computer through a receiver. The wireless keyboard is provided with a storage structure for storing the receiver. In the prior art, a keyboard is generally used with a handrest to reduce hand fatigue. However, after long-term use of the handrest, sweat stains adhere to the handrest, making it inconvenient to disassemble the handrest. At the same time, the installation of the handrest lacks a good supporting effect, resulting in an insecure connection between the handrest and the keyboard, and the handrest also lacks a cooling and heating effect.

[0003] For example, the wireless keyboard disclosed in the authorized patent document with the application number 202220565281.5 includes a bottom case, a circuit board, and a battery. An installation space is formed inside the bottom case, and both the circuit board and the battery are arranged in the installation space; it also includes a battery mounting bracket; the battery mounting bracket includes a battery mounting side and a circuit board connection side arranged opposite to each other. A battery mounting position is formed on the battery mounting side, and a connection part is provided on the circuit board connection side; the battery mounting bracket is arranged between the circuit board and the bottom case, with the battery mounting side facing the bottom case and the circuit board connection side facing the circuit board; the battery is fixed in the battery mounting position, and the connection part is fixedly connected to the circuit board. When assembling the keyboard, the battery can be first fixed to the circuit board through the battery mounting bracket and the wiring can be completed, and then the circuit board, key shafts, and the battery can be installed into the bottom case together, reducing the difficulty of battery installation and wiring operation and improving production efficiency.

[0004] The above-mentioned patent has the problem that after long-term use of the handrest, sweat stains adhere to the handrest, making it inconvenient to disassemble the handrest. At the same time, the installation of the handrest lacks a good supporting effect, resulting in an insecure connection between the handrest and the keyboard. Therefore, we need to provide a wireless keyboard with a handrest. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wireless keyboard with a handrest. When installing between the wireless keyboard body and the handrest board, both installation buckles on one side of the handrest board are inserted into the groove body on one side of the wireless keyboard body. Since the installation buckles are arc-shaped, they first contact the rollers and drive the rollers to rotate and squeeze the two moving frames away from each other. The moving frames slide on the sliding rods and squeeze the supporting springs until part of the rollers are located in the grooves on the surface of the installation buckles. Under the action of the supporting springs, the installation buckles are limited and fixed. At the same time, the metal support block in the first limiting slide rail is moved to the second limiting slide rail in the handrest board. At this time, one side of the metal support block is adsorbed to the magnetic block in the second limiting slide rail. The metal support block is located at the connection of the second limiting slide rail and the first limiting slide rail, playing a strong supporting role, and solving the problems raised in the above background art.

[0028] Two mounting buckles 3 fixedly installed on one side of the handrest plate 2 and a clamping mechanism 4 provided on one side of the wireless keyboard body 1 for limiting the two mounting buckles 3;

[0029] A support member 5 is provided between the wireless keyboard body 1 and the handrest plate 2 for strengthening connection;

[0030] The clamping mechanism 4 includes a groove body 41, a support spring 42, a sliding rod 43, a moving frame 44 and a roller 45. A groove body 41 corresponding to the two mounting buckles 3 is opened on one side of the wireless keyboard body 1. Both sides of the inner wall of the groove body 41 are provided with moving frames 44 through two support springs 42. Two sliding rods 43 are slidably installed inside the moving frame 44. One end of the sliding rod 43 is fixedly installed on the inner wall of the groove body 41. Two rollers 45 are rotatably installed on one side of the two adjacent moving frames 44. The convex part on the surface of the mounting buckle 3 is clamped between the four rollers 45.

[0031] The support member 5 includes a first limit slide rail 51, a second limit slide rail 52, a metal support block 53 and a magnetic attraction block 54. First limit slide rails 51 are opened on both sides of the wireless keyboard body 1. Second limit slide rails 52 are opened on both sides of the handrest plate 2. A metal support block 53 is slidably installed between the first limit slide rail 51 and the second limit slide rail 52. Magnetic attraction blocks 54 are installed on the inner walls of the first limit slide rail 51 and the second limit slide rail 52;

[0032] In this embodiment, when the wireless keyboard body 1 and the handrest plate 2 are installed, the two mounting buckles 3 on one side of the handrest plate 2 are both inserted into the groove body 41 on one side of the wireless keyboard body 1. Since the mounting buckle 3 is arc-shaped, it first contacts the roller 45 and drives the roller 45 to rotate and squeeze the two moving frames 44 away from each other. The moving frame 44 slides on the sliding rod 43 and squeezes the support spring 42 until part of the roller 45 is located in the groove on the surface of the mounting buckle 3. Under the action of the support spring 42, the mounting buckle 3 is limited and fixed. At the same time, the metal support block 53 in the first limit slide rail 51 is moved to the second limit slide rail 52 in the handrest plate 2. At this time, one side of the metal support block 53 is adsorbed by the magnetic attraction block 54 in the second limit slide rail 52. The metal support block 53 is located at the connection between the second limit slide rail 52 and the first limit slide rail 51, playing a strong supporting effect.

[0033] In order to facilitate the movement adjustment of the metal support block 53, a convex strip portion is integrally processed on one side of the metal support block 53.

An external connection port 63 is electrically connected to one side of the two water heating tubes 62. A water valve tube 64 is communicated with one side of the handrest plate 2;

[0035] Further, water is injected into the liquid storage cavity 61 through the water valve tube 64, and the power supply is connected through the external connection port 63 to heat the water heating tube 62 in the liquid storage cavity 61. The maximum temperature of the water heating tube 62 is 40°, and the power is relatively small, so as to realize the heating of the handrest plate 2, provide heat for the hands in winter, and in summer, water is filled into the liquid storage cavity 61 without heating, having a certain cooling effect.

[0036] The external connection port 63 is set as a USB port;

[0037] Specifically, the universality of the USB port enables users not to worry about the compatibility problems between devices, greatly improving the convenience of use.

[0038] In order to make the user use more comfortably and more ergonomically, the top of the handrest plate 2 is set as an inclined surface.

[0039] The two installation buckles 3 are set as alloy buckles;

[0040] Further, the alloy buckle has good rigidity, and the connection and support between the handrest plate 2 and the wireless keyboard body 1 are stronger.

[0041] When the wireless keyboard body 1 and the handrest plate 2 are installed in this device, both of the two installation buckles 3 on one side of the handrest plate 2 are inserted into the slot 41 on one side of the wireless keyboard body 1. Since the installation buckle 3 is arc-shaped, it first contacts the roller 45 and drives the roller 45 to rotate and squeeze the two moving frames 44 away from each other. The moving frames 44 slide on the sliding rod 43 and squeeze the support spring 42 until part of the roller 45 is located in the groove on the surface of the installation buckle 3. Under the action of the support spring 42, the installation buckle 3 is limited and fixed. At the same time, the metal support block 53 in the first limit slide rail 51 is moved to the second limit slide rail 52 inside the handrest plate 2. At this time, one side of the metal support block 53 is adsorbed by the magnetic block 54 in the second limit slide rail 52. The metal support block 53 is located at the connection of the second limit slide rail 52 and the first limit slide rail 51, playing a strong support effect.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
