Description

Rotary shaft positioning mechanism

The utility model relates to a rotating shaft positioning mechanism, in particular to a torsion elastic piece which is provided between the shaft hole and the shaft rod and which is provided with an elastic and inwardly protruding convex buckle portion, so that the shaft does not need additional parts in the shaft hole. You can reach the positioner.

The electronic products currently seen on the market, such as notebook computers, mobile phones, translators, PDAs (personal digital assistants), etc., all have a main body and a pivoting or deflection angle with respect to the main body. The screen, in order to achieve the aforementioned pivoting or yaw angle, is an invention of a hinge or shaft configuration.

For example, the new patent case of the Republic of China Patent No. 420321 discloses a fixed seat, a pivot, a positioning plate and a spring frame, wherein the fixed seat and the pivot can be respectively disposed on the body and the screen of the computer. A fixing hole is formed on one side of the fixing seat, and a horizontal groove is formed on the side of the coupling hole and communicates with the side of the coupling hole. The spring frame formed by the sheet body has a straight piece at one end and is formed on the side of the end of the straight piece. The protrusion at the other end is a shaft hole of the hollow tube body for the shaft of one end of the pivot shaft, and the aforementioned tube spring frame can be disposed in the joint hole of the fixing seat and the working type transverse groove.

However, the assembly structure of the patent case is too complicated, and the manufacturing cost is high, and the wear of one part affects the overall function.

Another new patent of the Republic of China Patent Notice No. M388814 For the case, please refer to FIG. 1 , which discloses a shaft structure with elastically resisting positioning, which is provided with a shaft barrel, and a shaft rod is arranged in the shaft barrel, and a fixed part is arranged in the shaft barrel, and the shaft is outside the shaft. The rim is provided with a positioning portion that can be positioned with the fixing portion. The rotating shaft is disposed on the lower side of the shaft 100 with a resilient yaw and elastic displacement resisting member 200. The end of the resisting member 200 is formed with a resisting portion 201. The outer edge of the shaft 100 is provided with a notch 101 on the side of the positioning portion. The abutting portion 201 is abutted in the notch 101. The elastic displacement capability of the resisting member 200 is used to form the shaft cylinder and the shaft 100. When positioning, the shaft 100 is pushed to eliminate the gap between the shaft barrel and the shaft 100, so that the shaft is more stably positioned, so that the article using the shaft does not sway during the positioning state.

However, the patent uses a resisting member having an elastic yaw and an elastic displacement under the shaft, and the resisting member has a problem of being easily broken.

In view of the shortcomings of the prior art mentioned above, the creators have developed and designed the new type after careful research and experimentation and improvement based on the manufacturing experience and technical accumulation of various shafts. A new spindle positioning mechanism to eliminate the lack of prior art.

Therefore, the present invention aims to provide a rotating shaft positioning mechanism, which is provided with a torsion elastic piece between the shaft and the shaft hole, and the thickness of the torsion elastic piece is slightly larger than the gap between the shaft and the shaft hole, so that the shaft and the shaft hole For tight fit assembly.

According to the novel shaft positioning mechanism, the torsion spring piece is integrally formed of a metal material, and is provided with a convex buckle portion protruding inwardly, and the shaft rod is provided with a groove for engaging with the convex buckle portion. Thereby, the shaft can be easily rotated and positioned in the shaft hole, which is the second purpose of the present invention.
