DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 As shown, the utility model discloses a pull keyboard fine-tuning module, including a distance fine-tuning component 600, the distance fine-tuning component 600 includes a fine-tuning screw rod 610 and a fine-tuning block 620 that can move on the fine-tuning screw rod 610, and also includes a pull hook 500, the pull hook 500 includes a hook seat located below the fine-tuning block 620 and a hook body 520 arranged at the lower end of the hook seat, the hook body 520 is used to hook the lower side of the keycap, the two sides of the hook body 520 protrude from the lower end of the hook seat, and the other two sides of the hook body 520 do not protrude from the lower end of the hook seat, when the hook body 520 is inserted into the gap between the two keycaps, it enters between the two keycaps to be pulled in an attitude of facing the keycaps without protruding from the two sides of the lower end of the hook seat, so when the hook seat is produced, the width of its lower end can be close to the gap width between the two keycaps, the length L1 of the hook body 520 is greater than the gap between the two keycaps, and the width W1 of the hook body 520 is close to the width of the lower end of the hook seat (the width here refers to the maximum radial size of the entire hook seat, Figure 4 The lower end of the middle hook seat is cylindrical, so the width mentioned here should be the diameter of the lower end of the hook seat), and the overall volume is larger than that in the prior art, thereby increasing the strength of the hook body 520.

[0023] In order to realize that the hook body 520 pulls up the keycap, a rotation drive component 400 is provided here. The rotation drive component 400 is arranged on the fine-tuning block 620, and the rotation drive component 400 is used to drive the fine-tuning block 620 to rotate ninety degrees under the hook seat, so that the hook body 520 protrudes from both sides of the micro-needle part 510 and rotates to the bottom of the keyboard, so that the keycap can be lifted upward by the hook body 520 when the base 530 moves upward, thereby providing pulling force for the keycap test.

[0024] The keyboard fine-tuning module provided by the embodiment of the utility model can insert the hook body 520 into the gap between the two key caps in a posture of facing the key caps without protruding from the two sides of the lower end of the hook seat. Therefore, when the hook seat is produced, the width of its lower end can be close to the width of the gap between the two key caps, and the length L1 of the hook body 520 is greater than the gap between the two key caps. The width W1 of the hook body 520 is close to the width of the lower end of the hook seat (the width here refers to the maximum radial dimension of the entire hook seat, Figure 4 The lower end of the middle hook seat is cylindrical, so the width mentioned here should be the diameter of the lower end of the hook seat), the overall volume is larger than the volume in the prior art, the strength of the hook body 520 is increased, and only one rotation action is required to align the hook with the keycap, and the structure is simple.

[0025] like Figure 2 As shown, the aforementioned rotation driving assembly 400 includes a rotating shaft 420 rotatably mounted below the fine-tuning block 620 , a gear 430 fixed on the rotating shaft 420 , and a motor 410 for driving one of the rotating shafts 420 to rotate; two adjacent gears 430 are meshed.

[0026] In this embodiment, when the motor 410 is working, it can drive one of the rotating shafts 420 to rotate, so that due to the action of the gear 430, multiple rotating shafts 420 can rotate together, and then multiple hook seats can be rotated synchronously by 90 degrees.

[0027] like Figure 1 and Figure 2 The above-mentioned hook 500 includes a base 530 fixed to the lower end of the rotating shaft 420 and a microneedle portion 510 integrally formed at the lower end of the base 530 (the microneedle portion 510 serves as the lower end of the hook seat), and the hook body 520 is fixed to the lower end of the microneedle portion 510, and the diameter of the microneedle portion 510 can be selected to be 17 to 19 mm.

[0028] like Figure 1 As shown, in order to achieve position adjustment of the hook body 520 so that it can adapt to the keycap spacing on different keyboards, the distance fine-tuning assembly 600 mentioned above also includes an internal threaded barrel 640, which is embedded in the fine-tuning block 620, and a limit ring 641 is fixed on the outer circumference of the internal threaded barrel 640 for limiting the internal threaded barrel 640 from being separated from the fine-tuning block 620. The internal threaded barrel 640 is threadedly connected to the fine-tuning screw 610. When the internal threaded barrel 640 rotates, it can generate thread force with the fine-tuning screw 610, and then drive the fine-tuning block 620 to move on the fine-tuning screw 610, thereby adjusting the positions of the two hook bodies 520 individually.

[0029] Preferably, one end of the internal threaded barrel 640 protrudes from the fine-tuning block 620 , and the end of the internal threaded barrel 640 protruding from the fine-tuning block 620 is provided with anti-slip grooves, so that the protruding part can be manually rotated to realize the rotation of the internal threaded barrel 640 .

[0030] In addition, it is also necessary to equip the fine-tuning block 620 with a corresponding guide rod 630 to prevent the fine-tuning block 620 from rotating along the internal threaded barrel 640 .

[0031] Furthermore, the above-mentioned keyboard fine-tuning module further includes a bracket 300 , and both ends of the fine-tuning screw rod 610 are fixed on the bracket 300 , thereby locking the position of the fine-tuning screw rod 610 .

[0032] like Figure 1 A moving assembly 100 is provided above the bracket 300. The moving assembly 100 includes a moving screw rod 120 and a moving nut 110 threadedly connected to the moving screw rod 120. A lifting cylinder 200 is installed on the moving nut 110. The lower end of the piston rod of the lifting cylinder 200 is fixedly connected to the bracket 300. When the moving screw rod 120 rotates, the moving nut 110 can be driven to move, and then the moving nut 110 can drive the lifting cylinder 200 and the bracket 300 to move, so as to change the position of the hook body 520, so that it can test the keycaps at different positions of the keyboard.

[0033] The working principle and use process of the utility model are as follows: when in use, the keyboard is placed under the device, and then the fine-tuning block 620 drives the hook 500 to move by rotating the internal threaded cylinder 640, until each hook body 520 is adjusted to align with the gap position between the two key caps, and then the lifting cylinder 200 drives the hook 500 to move downward, and at the same time, the rotating drive component 400 can drive the hook 500 to rotate ninety degrees, so that the hook body 520 enters the gap between the two key caps to be pulled in an attitude of not protruding from both sides of the micro-needle part 510 and facing the keyboard. After entering the gap, the rotating drive component 400 drives the hook 500 to rotate ninety degrees again, so that the hook body 520 protrudes from both sides of the micro-needle part 510 and rotates to the bottom of the keyboard, so that when the lifting cylinder 200 drives the base 530 upward, the key cap can be pulled upward through the hook body 520 to provide pulling force for the key cap test.
