[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the lever outward, the baffle slides inside the thin shell against the elastic force of the spring, causing the plug block to be pulled out of the plug slot. After the keyboard is rotated around the rotating rod to a suitable angle, the lever is released, and the spring pushes the baffle to slide, allowing the plug block to be inserted into another plug slot, thus fixing the keyboard. This reduces the space occupied by the keyboard when it is not in use, making it easy to carry and store.

A plug block 11 is fixedly connected to the bottom of the baffle 8.

[0036] Specifically, Keyboard 1, as the main body of the folding keyboard, provides the mounting base for other components. Rotating rod 3 is fixed to both sides of Keyboard 1, providing rotational support for the sleeve rod 4, enabling the folding and unfolding of Keyboard 2. The sleeve rod 4 is rotatably connected to the rotating rod 3, and Keyboard 2 is fixed to the outside, transmitting the rotational motion. Keyboard 2, through the cooperation of the sleeve rod 4 and the rotating rod 3, can be folded or unfolded relative to Keyboard 1, increasing the usable area of ​​the keyboard. The fixing component is used to fix the position of Keyboard 2 after the keyboard is unfolded. Turntable 5 is fixed to one end of the sleeve rod 4, and has an internal insertion slot 6 for connecting to the insertion block. The 11 components work together to achieve fixation. The thin shell 7 is fixed to the outside of the keyboard 1, providing sliding space for components such as the baffle 8 and the lever 9. The baffle 8 slides inside the thin shell 7, causing the plug block 11 to be inserted into or removed from the plug slot 6. The plug block 11 is fixed to one side and the bottom of the baffle 8 and is inserted into the plug slot 6 of the turntable 5 to fix the keyboard 2. The lever 9 is used to pull the baffle 8 to overcome the elastic force of the spring 10, so that the plug block 11 is disengaged from the plug slot 6. The spring 10 is used to provide elastic force to push the baffle 8 so that the plug block 11 is inserted into the plug slot 6. The winding assembly is used to manage the winding and unwinding of the keyboard data cable 14.

A rotating handle 21 is fixedly connected to the outer side of the rotating shaft 13.

[0038] Specifically, the take-up box 12 is used to accommodate other components of the take-up assembly, providing space for the take-up of the data cable 14. The rotating shaft 13 rotates to achieve the take-up and take-up of the data cable 14. The force spring 22 is used to store force when the data cable 14 is pulled out and release the elastic force when it is taken up, causing the rotating shaft 13 to reverse. The ratchet 15 cooperates with the pawl 17 to prevent the rotating shaft 13 from reversing after the data cable 14 is pulled out. The fixing rod 16 provides rotational support for the pawl 17. The pawl 17 rotates outside the fixing rod 16 and engages with the ratchet 15, which is controlled by the spring 18. The spring 18 is used to maintain the engagement state and prevent the rotating shaft 13 from reversing. The spring 18 is used to provide elasticity to keep the pawl 17 and ratchet 15 engaged. The data cable 14 is wound up and down by rotating the rotating shaft 13 and is used to connect the keyboard and the device. The handle 20 drives the pawl 17 to rotate through the connecting rod 19, so that the pawl 17 is separated from the ratchet 15. The connecting rod 19 is used to transmit the action of the handle 20 and drive the pawl 17 to rotate. The rotating handle 21 is fixed on the outside of the rotating shaft 13 and is used to manually assist in rotating the rotating shaft 13 to realize the winding of the data cable 14.

[0039] Reference Figure 1 - Figure 6 The turntable 5 has two insertion slots 6 inside. The outer side of the insertion block 11 is inserted into the outer side of one of the insertion slots 6. The outer side of the insertion block 11 is slidably connected to the inside of the thin shell 7. The outer side of the pull rod 9 is slidably connected to the inside of the thin shell 7. One end of the spring 10 is fixedly connected to the outer side of the baffle 8, and the other end of the spring 10 is fixedly connected to the inside of the thin shell 7. The outer side of the handle 20 is slidably connected to the inside of the cable take-up box 12. One end of the force spring 22 is fixedly connected to the outer side of the cable take-up box 12, and the other end of the force spring 22 is fixedly connected to the outer side of the pivot 13. The outer side of the pivot 13 is rotatably connected to the inside of the keyboard 1.

[0040] Specifically, the turntable 5 is used to connect with the rotating structure of keyboard 2, the insertion slot 6 is used to cooperate with the insertion block 11 to fix the keyboard after it is unfolded, the insertion block 11 can slide inside the thin shell 7 and be inserted into the insertion slot 6 to fix the position of keyboard 2 relative to keyboard 1, the thin shell 7 provides sliding space for the insertion block 11 and the pull rod 9 to ensure the normal operation of the fixing components, the pull rod 9 is used to pull the baffle 8 to overcome the elastic force of the spring 10 and make the insertion block 11 disengage from the insertion slot 6, the spring 10 is used to provide elastic force to push the baffle 8 and make the insertion block 11 insert into the insertion slot 6, the handle 20 is used to drive the pawl 17 to rotate through the connecting rod 19 to release the engagement of the ratchet 15, the force spring 22 is used to store force when the data cable 14 is pulled out, and drive the rotating shaft 13 to reverse and rewind the data cable 14 when released, the rotating shaft 13 rotates inside the keyboard 1 to rewind the data cable 14 and drive the ratchet 15 to rotate.

[0041] Working principle: To fold the keyboard, simply pull the lever 9 outward. The lever 9 causes the baffle 8 to slide inside the thin shell 7, overcoming the elastic force of the spring 10. This allows the plug block 11 to be pulled out from one of the plug slots 6, thus unlocking the keyboard 2 in the unfolded position. At this point, the keyboard 2 can rotate around the rotating rod 3 to a suitable angle. Then, release the lever 9. Under the action of the spring 10, the baffle 8 connected to it will slide inside the thin shell 7. The plug blocks 11 on one side and at the bottom of the baffle 8 will then insert into another plug slot 6 in the turntable 5, stably fixing the keyboard 2 in the folded position.

[0042] When the data cable 14 is needed, pull the data cable 14 outward. The data cable 14 drives the rotating shaft 13 fixed to it to rotate inside the cable retractor 12. During the rotation of the rotating shaft 13, the force spring 22 sleeved on its outside will be twisted and stored. At the same time, the ratchet 15 fixed on the outside of the rotating shaft 13 also rotates. Since the pawl 17 is engaged with the ratchet 15 under the action of the spring 18, it can prevent the rotating shaft 13 from reversing, thereby keeping the data cable 14 in the pulled-out use state.

[0043] When it is necessary to rewind the data cable 14, pull the handle 20 to slide inside the cable rewind box 12. The handle 20 drives the pawl 17 to rotate around the fixed rod 16 through the connecting rod 19, so that the pawl 17 is separated from the ratchet 15. At this time, the force spring 22 releases elastic potential energy, drives the rotating shaft 13 to reverse, and then rewinds the data cable 14 to the outside of the rotating shaft 13.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
