[0002] A keyboard testing device is a device used to test the performance of a keyboard. It usually consists of a physical keyboard and an interface connected to a computer, and can be used to test performance indicators such as the key sensitivity, response speed, and key pressing force of the keyboard. The keyboard testing device can help manufacturers and users evaluate the quality of the keyboard and detect whether the keyboard has faults or damages. For example, the utility model patent with the authorization announcement number CN206470370U proposes a keyboard testing machine, which includes a device support, a carrier assembly for placing the keyboard to be tested, and a pressing assembly for performing pressing operations on the keyboard to be tested. The carrier assembly is fixedly arranged on the device support, and the pressing assembly is movably arranged on the device support by means of a moving assembly; it also includes a central control group fixedly arranged on the device support for controlling the overall operation of the device and recording the test results.

[0003] When the existing keyboard testing device is in use, the position of the poking rod for hitting the keyboard is relatively fixed. For specific keys, it is necessary to disassemble and assemble the corresponding poking rod at the corresponding position, which is not convenient enough. Therefore, it needs to be improved.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A keyboard testing device includes a box. On the front surface of the box, there are a large screen, a small screen, a rocker switch, and a start button. On the top of the box, there is a bottom plate. At the upper end of the bottom plate, a plurality of bearing sleeves are installed, and a driving shaft is installed inside each bearing sleeve. At the top of the driving shafts, there is a panel in common. On the upper end of the panel, a stepping motor is fixedly installed, and the stepping motor is connected to the driving shaft through a coupling. Inside the panel, there is a cross beam fixedly connected. A plurality of connecting pieces are installed on the beam body of the cross beam through bolts. The upper end of the connecting piece is slidably connected with a support rod. The end of the support rod is fixedly connected with a clamping sleeve, and a poking rod is fixedly connected inside the clamping sleeve.

[0006] Preferably, the panel is in a U shape and is made of stainless steel. Through the setting of the panel, it is convenient to fix the fixture composed of the cross beam, the connecting piece, the support rod, and the clamping sleeve.

[0007] Preferably, the bottom of the box is fixedly connected with a suction cup cylinder, the inner side of the suction cup cylinder is slidably connected with a piston, the upper end of the piston is fixedly connected with a hollow column, a bidirectional screw is installed inside the box through a bearing, the threaded portion of the bidirectional screw is threadedly connected with a ramp block, and the ramp block is slidably connected with the hollow column. The ramp block can be moved laterally by the relative thread cooperation between the ramp block and the bidirectional screw.

[0008] Preferably, the bidirectional screw rod is provided with forward and reverse threads on its rod body, and the forward and reverse threads are symmetrically distributed on the bidirectional screw rod. By providing the forward and reverse threads, the two inclined plane blocks can be moved toward or away from each other.

[0009] Preferably, the piston is block-shaped and made of rubber. By arranging the piston into a block shape, the lifting and lowering of the piston itself has a self-guiding effect.

[0010] Preferably, one end of the bidirectional screw located outside the box is fixedly connected with a knob, and the knob is made of plastic. The setting of the knob makes it easy to rotate the bidirectional screw.

[0011] Preferably, the top of the inclined plane block is slidably connected to the inner surface of the box, and the lower end of the inclined plane block is provided with an inclined plane. Through the setting of the inclined plane on the inclined plane block, after it is inserted into the hollow column, the hollow column can be subjected to an upward pulling force.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model sets a group of fixtures composed of a crossbeam, a connecting piece, a support rod and a jacket, and then installs a pneumatically controlled poking stick on the jacket. Then, the height and length of the fixture are adjustable, so that multiple buttons at different positions can be tested simultaneously to improve efficiency.

[0014] 2. The utility model arranges a suction cup cylinder with a piston at the bottom of the box of the device, and then uses a bidirectional screw to control the two inclined plane blocks to move toward each other at the same time. Then the inclined plane block is inserted into the hollow column on the piston, so that the hollow column and the piston move upward, and then the air in the suction cup cylinder is sucked, and the suction cup cylinder is adsorbed on the desktop, thereby ensuring the stability of the device when in use.
