Benefits of technology
"The present invention provides a rotating shaft structure for a supporting frame that reduces stress on the rotating shaft and locks the supporting arm steady. The structure includes a carrying base, a supporting arm, and a connecting base. The carrying base has a base board, an upper fixing base, and a lower fixing base. The supporting arm has an arm, two sleeves, a bearing, and a locking assembly. The connecting base has a carrying board, two connecting flakes, and a locking assembly. The bearings are placed in the sleeves, and the locking assemblies are used as a locking element. This structure ensures that the rotating shaft is fully supported when the supporting arm rotates."
Problems solved by technology
When the supporting arm is rotated, wear and tear becomes worse.
When the supporting arm is locked tightly, it is difficult to rotate the supporting arm.

Embodiment Construction
[0018]Reference is made to FIGS. 2, 3, and 4. The rotating shaft structure for a supporting frame includes a carrying base 1, a supporting arm 2, and a connecting base 3. The carrying base 1 includes a base board 11, an upper fixing base 12, and a lower fixing base 13. There are a plurality of fixing holes 111 on the base board 1, there is a through hole 121 on the upper fixing base 12, and there is a pivoting hole 131 on the lower fixing base 13.
[0019]The supporting arm 2 is pivoted with the carrying base 1. The supporting arm 2 includes an arm 21, a first sleeve 22 and a second sleeve 22′, a bearing 23, and a first locking assembly 24. In the first sleeve 22 and the second sleeve 22′ located at the two opposite sides of the arm 21, there is a rotating shaft hole 221. On the two ends of the rotating shaft hole 221, there is a receiving space 222 having a larger inner diameter and a shoulder part 223. The bearing 23 is placed into the receiving space 222. The first locking assembly ...

A rotating shaft structure for a supporting frame is used for supporting a thin computer or a plate screen. The rotating shaft structure includes a carrying base, a supporting arm, and a connecting base. The carrying base is fastened on a wall or a column. Bearings are placed into the first sleeve and the second sleeve located at the two opposite sides of the supporting arm. The carrying base is steadily pivoted with the supporting arm via the first locking assembly. The connecting base is steadily pivoted with the supporting arm via the second locking assembly. Because the bearings are placed in the first sleeve and the second sleeve, the first locking assembly and the second locking assembly are merely used as a locking element, and the bearing fully supports the rotating shaft when the supporting arm rotates. The connecting base is used for connecting with a thin electronic device.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a rotating shaft structure for a supporting frame. In particular, this invention relates to a rotating shaft structure for a supporting frame that is used for supporting a thin computer or a plate screen.[0003]2. Description of the Related Art[0004]In order to let users position thin electronic devices, such as plate computers, LCDs, LCD TVs and plasma TVs, on different locations or in different ways, such as on walls or ceilings etc, many supporting frames or hanging frames for supporting or carrying electronic devices have been developed.[0005]FIG. 1 shows a rotating shaft structure for a supporting frame for supporting electronic devices of the prior art. The rotating shaft structure for a supporting frame includes a base board 7, a supporting arm 8, and a connecting board 9. At one side of the base board 7, there is an upper pivoting board and a lower pivoting flake 71. There are piv...
