Description

[Technical field]

[0001] The utility model relates to the technical field of computer keyboards, in particular to a dustproof keyboard for computers. [Background technology]

[0002] The keyboard is the most commonly used and most important input device. English letters, Chinese characters, numbers, punctuation marks, etc. can be input into the computer through the keyboard, so as to issue commands to the computer, input data, etc. There are also some keyboards with various shortcut keys. As time goes by, independent products with various shortcut functions are gradually appearing on the market. They are sold separately and come with dedicated drivers and setting software. Personalized operations can also be achieved on compatible computers. The existing keyboards are as follows:

[0003] For example, patent publication number CN113810036A discloses a keyboard, which includes a support structure, a key structure, a magnetic drive sensor and a lower magnetic conductive layer; the key structure is arranged on the support structure and includes a lifting mechanism, a key cap and a magnet arranged on the lifting mechanism, and the key cap moves up and down relative to the support structure through the lifting mechanism. The magnet is arranged on the key cap or the lifting mechanism, and the magnetic drive sensor is arranged corresponding to the magnet, so that when the key cap moves downward, the magnet approaches the magnetic drive sensor, and the lower magnetic conductive layer includes a main body and a surrounding portion extending upward from the main body, and the main body is arranged below the lifting mechanism, the magnetic drive sensor and the magnet, and the surrounding portion surrounds the magnetic drive sensor. The keyboard of the present invention has a magnetic conductive layer, which can shield or suppress the influence of the external magnetic field of the keyboard on the inside of the keyboard;

[0004] Although the above invention can input punctuation marks into the computer, when people press the keycaps, some dust will enter the keyboard PCB board. When dust accumulates inside the PCB board, the probability of short circuit on the PCB board is easily increased. [Contents of the utility model]

[0005] The purpose of the utility model is to solve the problems in the prior art and to provide a computer dustproof keyboard, which can prevent dust from entering the keyboard.

[0006] To achieve the above-mentioned purpose, the utility model proposes a computer dustproof keyboard, comprising a housing, a keycap elastically slidably connected to the housing in a vertical direction, and a circuit board structure arranged in the housing and opposite to the keycap, wherein a sliding groove for the keycap to slide is opened on the housing;

[0007] A dust block is fixedly connected to the sliding groove;

[0008] The dust block is provided with an inclined surface 1 inclined toward the inside of the shell;

[0009] The bottom surface of the key cap is elastically slidably connected to a moving block 1 which slides toward the inclined surface 1;

[0010] The moving block 1 is provided with an inclined surface 2, the inclined surface 1 can be in contact with the inclined surface 2, and the inclined surface 2 can slide along the inclined surface 1.

[0011] Preferably, one end of the moving block away from the keycap is fixedly connected to a positioning block, the positioning block is arranged in an arc shape, and a moving groove for the positioning block to enter is opened on the dustproof block.

[0012] Preferably, a connecting block is fixedly connected to the bottom surface of the key cap, and the connecting block is connected to the circuit board structure. A spring 1 is fixedly connected to the connecting block, and the spring 1 is fixedly connected to the moving block 1.

[0013] Preferably, a sealing block 1 arranged in a vertical direction is fixedly connected to the bottom surface of the key cap, and the sealing block 1 is arranged in an L shape. A sealing groove 1 for sliding of the sealing block 1 is provided on the shell.

[0015] Preferably, a limiting block is fixedly connected to the dustproof block, and one end of the limiting block is arranged opposite to the moving block.

[0016] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model arranges an inclined surface 1 of the dustproof block on the sliding groove in contact with an inclined surface 2 on the moving block 1. When the moving block 1 slides, the two are always in a state of contact, thereby reducing the situation where dust enters the interior of the shell. By making the dustproof block contact with one surface of the moving block during the sliding process, dust can be reduced from entering the PCB board, thereby reducing the probability of short circuit of the PCB board due to the influence of dust, and further improving the service life of the keyboard.

[0028] Specifically, the arc-shaped positioning block 9 fixedly connected to the end of the moving block away from the keycap 2 is slidably connected to the moving groove 10 provided on the dustproof block 5 through the positioning block 9, thereby increasing the limiting effect of the moving block and reducing the left and right deviation of the moving block when sliding.

[0029] Specifically, a connecting block 11 is fixedly connected to the bottom surface of the keycap 2, and the connecting block 11 is fixedly connected to the shaft body 20, and is mainly used to connect the keycap 2 and the shaft body 20. By fixing a spring 12 on the connecting block 11, the spring 12 is fixedly connected to the moving block 7, so that the moving block 7 can be attached to the dustproof block 5.

[0030] Specifically, an L-shaped sealing block 13 vertically arranged at the bottom of the key cap 2 is fixedly connected, and the sealing block 13 is slidably connected with a sealing groove 14 provided on the housing 1, so as to block dust and further reduce dust from entering the PCB board 18.

[0031] Specifically, a sealing block 2 15 is fixedly connected to the sealing block 1 13 in a vertical direction, and the sealing block 2 15 is slidably connected to a sealing groove 2 16 provided on the housing 1 , thereby blocking dust and reducing dust from entering the PCB 18 .

[0032] Specifically, a limit block 17 is fixedly connected to the dustproof block 5 , and the limit block 17 is attached to the moving block 7 , so that the moving block 7 can be limited to prevent the moving block 7 from moving outside the housing 1 .
