Description

Rotary shaft torsion fixed structure

The present invention relates to a rotating shaft torsion fixing structure, in particular to a mechanism for moving between two relatively rotating shaft holes and a shaft through a circular polygonal elastic piece to enhance the torsional moment, and it is possible to achieve rotation at any angle. Positioning without loosening.

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 type of shaft torsion fixed structure, in order to eliminate the lack of prior art.

Therefore, the present invention aims to provide a rotating shaft torsion fixing structure, which is provided with a notched polygonal torsion elastic piece between the shaft and the shaft hole, and the thickness of the polygonal torsion elastic piece is slightly larger than that between the shaft and the shaft hole. Clearance, so that the combination of the shaft and the shaft hole can be properly rotated The tight fit structure for instant positioning.

According to the novel rotating shaft torsion fixing structure, the polygonal torsion elastic piece interposed between the shaft and the shaft hole is integrally formed of a metal material, and is formed with an upwardly protruding flange portion at the notched end thereof, and is conveniently mounted by a clamp. In the shaft hole, it is the second purpose of the new type.

According to the novel rotating shaft torsion fixing structure, the flange portion formed at the notched end of the polygonal torsion elastic piece not only provides convenient assembly, but also forms a multi-point struts with the peripheral edge of the shaft hole, and when the shaft is not positioned, it can be The deformation of the torsion elastic piece absorbs the tight fitting energy of the shaft and the shaft hole and is fixed, which is another object of the present invention.

In order to understand the purpose, shape, structure and function of the new model, the review committee can make a further understanding and understanding. The examples are as follows:

The "rotating shaft torsion fixing structure" of the present invention, as shown in Figures 2 and 3, includes: a pivot 300 and a shaft 400; wherein the pivot 300 has a connecting portion 301 at one end thereof. The connecting portion 301 is provided with a locking hole for connecting with a main body of an electronic product such as a mobile phone or a notebook computer, and the other end thereof is provided with a shaft hole 302, and the shaft hole 302 is a circular hole; the support shaft 400 is A connecting portion 401 is also disposed at one end. The connecting portion 401 is provided with a plurality of locking holes for contacting the cover of the main body, so that the cover body is oppositely closed and positioned on the main body, and the other end is provided with a A shaft that can be inserted into the shaft hole 302 of the pivot 402.

As shown in the figure, a torsion elastic piece 500 is further disposed between the pivot shaft 300 and the support shaft 400. The torsion elastic piece 500 is a circular polygonal elastic piece (the hexagonal shape or other polygonal shape), and one end is provided. The notch 501, the two ends of the notch 501 each form an outwardly protruding flange portion 5A, 5B, and the corner portions 51, 52, 53, 54, 55 are arcuately shaped to abut against the inner wall of the shaft hole 302. The thickness of the torsion spring 500 is slightly larger than the gap between the shaft 402 and the shaft hole 302. When the shaft 402 is inserted into the shaft hole 302, the torsion elastic piece 500 is interposed therebetween, and is tightly coupled to rotate.

As shown in Fig. 4, since the torsion elastic piece 500 is made of a resilient metal material, and because it is provided with an outwardly projecting flange portion, it is urged to pass through a closed space between the shaft 402 and the shaft hole 302. The elastic deformation thereof can form the apertures 50, 60 with different positions between the shaft 402 and the shaft hole 302, thereby achieving a non-fixed combination of the shaft 402 and the shaft hole 302 being able to be rotated and positioned in time.

The "rotating shaft torsion fixing structure" of the present invention can have various embodiments of the torsion elastic piece. As shown in Fig. 5, the torsion elastic piece 600 has a flange portion 6A, 6B which is radially convex. The torsion elastic piece 700 shown in Fig. 6 has a flange portion 7A, 7B which is radially outwardly turned. The torsion elastic piece 800 shown in Fig. 7 has an arcuate groove 81 which is fitted to the shaft in the inner surface of the elastic piece, and can be closely attached to the outer circumference of the shaft. The torsion spring piece 901 shown in Fig. 8 has a notched end 91A, 91B which is a cross section. The torsion shrapnel 902 shown in Fig. 9 is an octagonal shape In the polygonal elastic piece, both ends of the flange portions 92A and 92B are radially outwardly turned.

According to the above-mentioned rotating shaft torsion fixing structure, the cylindrical shaft hole and the shaft rod which are easy to process can be assembled quickly by the arrangement of the polygonal elastic piece, and can be rotated and positioned, the structure is simplified, and the cost can be greatly reduced, and Easy to repair features.

In summary, the new type of shaft torsion fixed structure does have an unprecedented innovative structure, which is not found in any publication, and there is no similar product on the market, so that its novelty should be undoubted. In addition, the unique features and functions of this new model are far from comparable to the conventional ones, so it is indeed more progressive than the customary ones, and the patent application is in accordance with the provisions of the application requirements for new patents in the Chinese Patent Law.
