Technical Field

[0001] The utility model relates to the technical field of keyboards, and more specifically, the utility model relates to a keyboard scissor foot quick pressing head. Background Technique

[0002] A keyboard is an instruction and data input device used to operate a computer device, and also refers to a group of function keys (such as a typewriter keyboard, a computer keyboard) for operating a machine or device through system arrangement. The keyboard is the most commonly used and main input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc. can be input into the computer, so as to send commands to the computer, input data, etc. An X-shaped bracket is designed under the keycap of a scissor foot keyboard, which together with the silicone bowl under the keycap plays a supporting role for the keycap. Since the bottom support points of the keycap are located at the four corners of the keycap, the scissor foot keyboard has relatively stable use characteristics. Users can press the keyboard with a fixed pressure at any point on the keycap, and there will be no phenomenon of uneven pressure or key jamming.

[0003] When installing the keyboard keys, it is necessary to press the keycap above the key base, and install the keycap on the key base through an insertion mechanism. At present, the keycap is pressed and installed manually by workers one by one, and this efficiency is not high. In order to improve the pressing efficiency of the staff, we propose a keyboard scissor foot quick pressing head. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a keyboard scissor foot quick pressing head to solve the problem that the keycap is currently pressed and installed manually by workers one by one, and this efficiency is not high as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A keyboard scissor foot quick pressing head includes an annular shell and a sleeve. The sleeve is placed above the annular shell. A circular plate is fixed below the sleeve, and the circular plate is sleeved outside the annular shell. An insertion mechanism is arranged between the circular plate and the sleeve. On both sides of the inner bottom of the annular shell, a blocking mechanism is arranged. Above the blocking mechanism, a plurality of keycaps are placed at intervals. A sliding hole is opened above the sleeve, and a sliding rod is slidably arranged in the sliding hole. One end of the sliding rod extends downward and is fixed with a lower plate, and the other end of the sliding rod extends upward and is fixed with an upper plate.

[0006] As a preferred technical solution of the utility model, an opening is arranged on one side of the annular shell, and a transparent plastic plate is fixed in the opening.

[0007] As a preferred technical solution of the utility model, anti-slip lines are arranged on the outer wall of the circular plate.

[0008] As a preferred technical solution of the present utility model, the insertion mechanism includes two rubber protrusions and an annular slot. The annular slot is opened on the outer wall above the annular housing. The two rubber protrusions are respectively fixed on both sides of the inner wall of the annular plate, and the rubber protrusions are inserted into the annular slot.

[0009] As a preferred technical solution of the present utility model, the blocking mechanism includes a groove and a cross bar. The groove is opened on the lower inner wall of the annular housing. One end of the cross bar is fixed on the side wall of the groove, and the other end of the cross bar is fixed on the other side wall of the groove. A collar is slidably sleeved outside the cross bar. A ramp-shaped baffle is fixed on one side of the collar. Springs are fixed on both sides of the cross bar. One end of the spring is fixed on the cross bar, and the other end of the spring is fixed on the collar.

[0010] As a preferred technical solution of the present utility model, an arc-shaped rubber pad is fixed at the bottom of the lower plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a plurality of key caps are sequentially placed in the annular housing. The blocking mechanism can block the downward movement of the key caps. When it is necessary to install the key caps above the key base, only need to place the annular housing above the key base, and then press down the upper plate. Pressing the upper plate can push the key caps downward through the lower plate. At this time, the ramp-shaped baffle will be driven to rotate, and the lowermost key cap will move above the key base through the ramp-shaped baffle. The force applied by the upper plate will make the key cap installed above the key base. When the upper plate is not stressed, the spring will drive the ramp-shaped baffle to reset, so as to prevent the upper key caps from falling. Repeating this operation, the staff can quickly press a plurality of key caps. Description of the Drawings

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 4 shown, the present invention provides a keyboard scissor foot quick pressing head, including a ring-shaped housing 1 and a sleeve 5. The sleeve 5 is placed above the ring-shaped housing 1. A ring-shaped plate 6 is fixed below the sleeve 5, and the ring-shaped plate 6 is sleeved outside the ring-shaped housing 1. Anti-slip patterns are provided on the outer wall of the ring-shaped plate 6. An insertion mechanism is provided between the ring-shaped plate 6 and the sleeve 5. Blocking mechanisms are provided on both sides of the lower part inside the ring-shaped housing 1. The blocking mechanisms can block the downward movement of the button cap 2. A plurality of button caps 2 are placed at intervals above the blocking mechanisms. A slide hole 10 is provided above the sleeve 5. A slide bar 9 is slidably arranged in the slide hole 10. One end of the slide bar 9 extends downward and is fixed with a lower plate 11, and the other end of the slide bar 9 extends upward and is fixed with an upper plate 12. The ring-shaped housing 1 is placed above the button base, and then the upper plate 12 is pressed downward. Pressing the upper plate 12 can drive the lower plate 11 to move. The lower plate 11 can push the button cap 2 downward. Pushing the button cap 2 downward can press the button cap 2 on the button base through the blocking mechanism. When the pressing of one button cap 2 is completed, the upper plate 12 is released, and the blocking mechanism will reset to block the downward movement of the button cap 2 again.

[0020] Wherein, an opening 3 is provided on one side of the ring-shaped housing 1, and a transparent plastic plate 4 is fixed in the opening 3. By observing the transparent plastic plate 4, it is convenient to understand the number of button caps 2 inside the ring-shaped housing 1.

[0021] Wherein, the insertion mechanism includes two rubber protrusions 8 and a ring-shaped slot 7. The ring-shaped slot 7 is provided on the outer wall above the ring-shaped housing 1. The two rubber protrusions 8 are respectively fixed on both sides of the inner wall of the ring-shaped plate 6, and the rubber protrusions 8 are inserted into the ring-shaped slot 7. The sleeve 5 can be limited by inserting the rubber protrusions 8 into the ring-shaped slot 7. When it is necessary to remove the sleeve 5 from above the ring-shaped housing 1, only need to pull the sleeve 5 forcefully to pull the rubber protrusions 8 out of the ring-shaped slot 7.

[0022] Among them, the blocking mechanism includes a groove 13 and a cross bar 14. The groove 13 is opened below the inner wall of the annular housing 1. One end of the cross bar 14 is fixed to the side wall of the groove 13, and the other end of the cross bar 14 is fixed to the other side wall of the groove 13. A collar 15 is slidably sleeved outside the cross bar 14. A ramp-shaped baffle 16 is fixed to one side of the collar 15. Springs 17 are fixed to both sides of the cross bar 14. One end of the spring 17 is fixed to the cross bar 14, and the other end of the spring 17 is fixed to the collar 15. Under normal circumstances, the ramp-shaped baffle 16 can block the key cap 2 above from moving downward. When the key cap 2 is stressed, it will push the ramp-shaped baffle 16 to rotate, so that it can move downward. At this time, the spring 17 will deform. When the ramp-shaped baffle 16 is not stressed, the spring 17 can reset the ramp-shaped baffle 16 through resetting.

[0023] Among them, an arc-shaped rubber pad 18 is fixed to the bottom of the lower plate 11. When the lower plate 11 pushes the key cap 2, the upper part of the key cap 2 can be protected through the arc-shaped rubber pad 18.

[0024] The working principle and usage process of the present utility model: By sequentially placing a plurality of key caps 2 in the annular housing 1, the blocking mechanism can block the key caps 2 from moving downward. By placing the annular housing 1 above the key base and then pressing the upper plate 12 downward, pressing the upper plate 12 can push the key caps 2 downward through the lower plate 11. At this time, it will drive the ramp-shaped baffle 16 to rotate. The lowermost key cap 2 will move above the key base through the ramp-shaped baffle 16. The force applied by the upper plate 12 will install the key cap 2 above the key base. When the upper plate 12 is not stressed, the spring 17 will drive the ramp-shaped baffle 16 to reset, so as to prevent the upper key caps 2 from falling. Repeating this operation, the staff can quickly press a plurality of key caps 2.
