DETAILED DESCRIPTION

[0015] 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.

[0016] The utility model provides Figures 1-3A foldable pad keyboard stand as shown, comprising a keyboard main body 1. Two sockets 2 are provided at one end of the keyboard main body 1. A locking device 3 is inserted into each of the two sockets 2. The locking device 3 includes a locking device housing 31. A plurality of longitudinal friction plates 32 are fixed inside the locking device housing 31. Two gear pieces 33 are provided between adjacent friction plates 32. The adjacent friction plates 32 are in contact with the gear pieces. One opposite end of each of the two gear pieces 33 is meshed with a paddle gear 34. The paddle gear 34 is integrally cast from a gear and a paddle. A rotating rod 35 is fixedly connected inside each of the gear piece 33 and the paddle gear 34. Both ends of the rotating rod 35 are rotatably connected to the inner wall of the locking device housing 31. Fixing frames 4 are fixedly connected to the paddles above the inner wall of the locking device housing 31. The lower fixing frame 4 is fixedly connected to an insertion plate 5. The insertion plate 5 is inserted into the inner cavity of the socket 2. A card frame 10 for clamping the pad is fixedly connected to the top end of the fixing frame 4. A pull rod 9 is provided at the top of the keyboard main body 1. A rubber pad for fixing the pad is provided on the inner wall of the card frame 10;

[0017] By setting the friction plates 32 to be in contact with the gear pieces 33, the friction between the friction plates 32 and the gear disks 33 can be increased, so that the gear pieces 33 can be positioned after rotating a certain angle, thereby locking the rotation angle of the pad. By setting the paddle gears 34, the gear pieces 33 in two rows at both ends can be rotated, preventing the gear pieces 33 from not rotating and being misaligned.

[0018] As Figure 1 shown, two jacks are provided on one side of the keyboard main body 1. One end of the pull rod 9 is slidably connected in the jacks. A Bluetooth device connected to the pad is provided inside the keyboard main body 1;

[0019] By setting the pull rod 9, after the pad rotates a certain angle, the support of the keyboard main body 1 can be increased, preventing the keyboard main body 1 from flipping due to the excessive weight of the pad.

[0020] As Figure 3 shown, two springs 11 are fixedly connected to the side of the push rod 81 away from the insertion rod 82. One end of the two springs 11 away from the push rod 81 is fixedly connected to the inner wall of the chute 7;

[0021] The springs 11 can push the push rod 81 to move. The movement of the push rod 81 drives the insertion rod 82 to move, so that one end of the insertion rod 82 passes through the through hole and inserts into the fixing hole 6, thereby fixing the locking device 3. When the locking device 3 is damaged, by pushing the push rod 81, the insertion rod 82 is separated from the fixing hole 6, and at this time the locking device 3 can be removed and replaced.

[0022] As Figure 3As shown in the figure, two sliding grooves 7 are provided at one end of the keyboard body 1, and a limiting device 8 is provided inside each of the two sliding grooves 7. The limiting device 8 includes a push rod 81. A plug rod 82 is provided on one side of the push rod 81. A through hole is provided between the socket 2 and the sliding groove 7. A 51 is provided on one side of the plug board 5. The plug rod 82 passes through the through hole and extends into the fixing hole 6. At this time, the plug board 5 can be fixed in the socket 2 by inserting the plug rod 82 into the fixing hole 6, thereby fixing the position of the locking device 3.

[0023] The working principle of the present utility model: When in use, first insert one end of the pad into the inner cavity of the card frame 10 for fixation. After the installation is completed, the angle of the pad can be adjusted by rotating the pad at this time. When the pad is adjusted, the bottom end of the pad drives the card frame 10 to rotate at this time. The fixing frame 4 is driven to rotate by the card frame 10. The picket gears 34 in one row are driven to rotate by the rotation of the fixing frame 4. The gear piece 33 is driven to rotate by the picket gears 34 in one row, and then the gear pieces 33 in the adjacent row are driven to rotate, so that the angle of the locking device 3 is rotated. When it is rotated to an appropriate angle, the pull rod 9 is pulled out at this time to support the keyboard body 1, so as to prevent the keyboard body 1 from flipping due to the excessive angle of the pad. Then, the keyboard body 1 can be used by connecting the Bluetooth inside the keyboard body 1 through the pad.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
