Detailed implementation mode

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and the detailed implementation mode, but the protection scope and application scope of the present utility model are not limited.

[0019] Embodiment: A keyboard capable of storing a keyboard cable, as Figures 1 - 4 shown, includes a keyboard main body 1, a keyboard cable 2, a support block 3, a wire spool 4, a pressing component and a limiting component. The keyboard cable 2 is arranged at the rear side inside the keyboard main body 1. Support blocks 3 are symmetrically and rotatably arranged on the left and right at the rear side of the bottom of the keyboard main body 1. Grooves matching with the support blocks 3 are opened at the bottom of the keyboard main body 1, so that when the support blocks 3 rotate and close, they can be embedded in the grooves at the bottom of the keyboard main body 1. A wire spool 4 is rotatably arranged at the rear side of the bottom of the keyboard main body 1. A handle is arranged at the bottom of the wire spool 4, which is convenient for manually controlling the rotation of the wire spool 4 to wind up the keyboard cable 2. The keyboard cable 2 inside the keyboard main body 1 winds around the wire spool 4. A pressing component is arranged on the wire spool 4, and a limiting component is arranged on the pressing component.

[0020] As Figure 3 and Figure 4 shown, the pressing component includes a first limit block 5, a second limit block 6 and a connecting spring 61. The upper right part of the wire spool 4 is fixedly connected with the first limit block 5. The second limit block 6 is slidably arranged at the inner top of the first limit block 5. The second limit block 6 is in contact and cooperation with the keyboard cable 2. A connecting spring 61 is arranged between the upper right part of the second limit block 6 and the right side inside the first limit block 5. When the wire spool 4 rotates, under the elastic force of the connecting spring 61, the second limit block 6 always presses the keyboard cable 2 against the outer side of the wire spool 4.

[0021] As Figure 4 shown, the limiting component includes a wire clamping block 7 and a reset spring 8. The wire clamping block 7 is slidably arranged inside the second limit block 6. The wire clamping block 7 is in a concave shape with an opening facing the keyboard cable 2. The wire clamping block 7 is in contact and cooperation with the keyboard cable 2. A reset spring 8 is connected between the upper right part of the top of the wire clamping block 7 and the inner top of the second limit block 6.

[0022] As Figure 4As shown in the figure, it further includes a connecting rod 9, a telescopic rod 10 and a guide ring 11. A connecting rod 9 is slidably arranged on the right side of the second limiting block 6. The left end of the connecting rod 9 passes through the second limiting block 6 and is fixedly connected to the right side of the wire clamping block 7. A telescopic rod 10 is slidably arranged at the right end of the connecting rod 9. A guide ring 11 is fixedly connected to the inner rear side of the keyboard main body 1. The axis of the wire winding shaft 4 is vertically aligned with the center of the guide ring 11. Both ends of the keyboard wire 2 in the keyboard main body 1 respectively slide through the front and rear sides of the guide ring 11. A guide groove is formed in the inner wall of the guide ring 11. The guide groove is an inclined elliptical structure with the left side higher than the right side. The right end of the telescopic rod 10 is slidably connected to the guide groove in the guide ring 11. When the right end of the telescopic rod 10 rotates counterclockwise and moves from the low point on the right side of the guide groove to the high point on the left side, the guide groove can squeeze the telescopic rod 10 to gradually move upward. When it rotates to the high point on the left side of the guide groove and continues to move to the low point on the right side, the guide groove can squeeze the telescopic rod 10 to gradually move downward.

[0023] When it is necessary to wind up the keyboard wire 2, rotate the wire winding shaft 4 counterclockwise to drive the first limiting block 5 to rotate counterclockwise. The first limiting block 5 drives the second limiting block 6, the wire clamping block 7, the connecting rod 9 and the telescopic rod 10 to rotate counterclockwise synchronously. Due to the elastic force of the connecting spring 61, the second limiting block 6 will always be subjected to a force towards the wire winding shaft 4, so as to press the keyboard wire 2 tightly on the outer side of the wire winding shaft 4. The wire clamping block 7 can press the top surface of the keyboard wire 2 to play a limiting role. At the same time, the end of the telescopic rod 10 can rotate along the guide groove in the guide ring 11. The guide groove can squeeze the telescopic rod 10 to gradually move upward, driving the connecting rod 9 and the wire clamping block 7 to move upward, and the return spring 8 is compressed, so as to vacate the position above the keyboard wire 2, enabling the keyboard wire 2 to be wound circumferentially around the outer side of the wire winding shaft 4 from bottom to top. When the end of the telescopic rod 10 rises to the uppermost side of the guide groove, the guide groove can squeeze the telescopic rod 10 to gradually move downward, and the return spring 8 will return to its original state, driving the connecting rod 9 and the wire clamping block 7 to move downward. The wire clamping block 7 can push the keyboard wire 2 downward, enabling the keyboard wire 2 to be wound circumferentially around the outer side of the wire winding shaft 4 from top to bottom again. Repeating like this, the keyboard wire 2 can be wound layer by layer on the outer side of the wire winding shaft 4. And whenever the number of winding layers of the keyboard wire 2 increases, the keyboard wire 2 will squeeze the second limiting block 6 to move away from the wire winding shaft 4, and the connecting spring 61 is compressed. Under the elastic force of the connecting spring 61, the second limiting block 6 can always press the keyboard wire 2 tightly to play a limiting role. If the length of the keyboard wire 2 released is not enough, similarly, by rotating the wire winding shaft 4 clockwise, an appropriate length of the keyboard wire 2 wound on the wire winding shaft 4 can be released, which is convenient for adjusting the use length of the keyboard wire 2 according to needs, and is convenient to use, saving time and effort.

[0024] As Figure 5As shown in the figure, it further includes a protection plate 12 which is slidably arranged at the inner rear side of the keyboard main body 1. When the keyboard is not needed, by rotating the wire winding shaft 4 counterclockwise, the keyboard wire 2 is completely received and wound inside the keyboard main body 1. By pulling the protection plate 12 to the right, the protection plate 12 completes the closing of the keyboard main body 1, which is convenient for neatly storing the keyboard wire 2, effectively preventing the keyboard wire 2 from being exposed outside and damaged, and at the same time is also convenient for carrying and placing the keyboard.

[0025] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
