[Prior Art] According to the flat panel display, such as liquid crystal display, LCD TV or TV, etc., it has gradually replaced the traditional image tube (CRT) because of its advantages of light weight, thinness and low radiation. )monitor. Since the liquid crystal and the plasma monitor have a viewing angle when viewing, the "display shaft and the base are provided with a rotating shaft" to connect the display and the base, and to adjust the tilt angle of the display relative to the base. After the user has used it for many years, there are the following shortcomings: 1. The fatigue of the stop element and the function of the function: The display is used to adjust the angle of the tilting of the base with the shaft, so as to avoid pulling the transmission signal to the wire of the display device. There is a stop-loading element with a maximum rotation angle limit, such as a shaft stop stop design, etc., to control the maximum angle of the display relative to the base. However, this long-lasting stop design is used after long-term use. After the shaft has repeatedly resisted the smashing of the slab, it often causes the smashing element to wear, smash, or bear the maximum torque failure, so as to limit the failure of the maximum angle of the display, causing the pulling of the wire and causing damage. There are many restrictions on the design of the rotating bracket: Wei Liang has both the shaft design to improve the stop state when the maximum elevation angle is turned to 200950672 / . / , · On-axis energy sleeve There are generally restrictions on the number or type of components. That is to say, in terms of the private axis of the turn, the money is transferred to the domain, or the size is closed, or to match the load. In other words, the design of the rotating bracket is changed. It is also necessary to consider the original functions and limitations in order to be effective. It can be seen that there are still many shortcomings in the above-mentioned conventional methods, which is not a good design, and needs to be improved. [Summary of the Invention] Ο The purpose of the present invention is A double-stop rotary shaft structure is provided, which utilizes a double anti-twist force to reconcile the side material-components, and reads the I maximum torque which is higher than the maximum thrust contact. The second purpose of the present invention is to provide a modified part. Less, in line with the limit. Double stop shaft structure. The double stop shaft structure for achieving the above purpose is set on a rotating shaft, which is mainly used to connect the display and the base to adjust the tilt of the display relative to the base.

The upper bracket portion 21 and the lower stopper portion 22 of the rotary bracket are formed by punching the rotary rack 2 with a press machine. The shaft 1 has a shaft section 12, an outer edge 14 and a fixed portion u. The shaft section 12 is provided with at least one plane 13 so that the shaft section 12 has a non-circular cross section, and the circular bracket 23 and the end of the rotating bracket 2 are provided. The three sets of holes 32 are pierced, and the sleeve 3 is fixed, the outer edge 14 and the fixed portion u are prevented from coming out of the rotating bracket 2. The shaft! The fixing portion u is formed by turning the rotating shaft so as to protrude from the outer edge 14 into an annular shape, and then punching the excess portion to form. Or when manufacturing the shaft, it is integrated with the shaft. The second embodiment is a side view of the embodiment of the present invention, and the second figure is a schematic view of the embodiment of the present invention. In the second embodiment, the upper portion of the upper stop portion 21 has a certain abundance portion 11. When the rotary cradle 2 is tilted about the rotary shaft 1 ^, the upper stopper portion 21 thereof abuts against the rotary shaft 1 stopper portion 11', that is, a stopper force is applied to the rotary bracket 2. In the third figure, and can be compared with the portion not shown in the second figure, the lower jaw portion 22 corresponds to the position and has a flange 3 when the rotating bracket 2 the lower portion 22 abuts the stop tab 3 At the edge 31, a detent force is also applied to the rotating carriage 2.
