[0003] In order to ensure the full coverage of the angle, the movement stroke needs to be greater than ±180°. Now the common structural form is the structure of the limit collision block and two sets of limit pendulum blocks. However, for the state of no gravity in space, the pendulum block can swing freely in the space, which is reliable. Insufficient performance, and the two sets of limit pendulum blocks do not meet the requirements of lightweight space

Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0028] The invention relates to the limitation of the rotation angle of a rotating shaft, in particular to a single-point rotation limiting mechanism. This mechanism can be used in equipment that needs to limit the rotation angle of the rotating shaft, such as the azimuth axis of a two-dimensional turntable in space.
[0029] According to the present invention provides a single-point rotary limit mechanism, such as figure 1 As shown, it includes a swing rod mount 1, a limit swing rod assembly, a leaf s...

The invention provides a single point rotation limiting mechanism, comprising a swing rod mounting seat (1), a limit swing rod assembly, a leaf spring assembly (3) and a stopper (4), wherein the limitswing rod assembly is provided on the swing rod mounting seat (1), one end of the leaf spring assembly (3) is fastened to the swing rod mounting seat (1), and the other end of the leaf spring assembly (3) is movably connected to the limit swing rod assembly. The stopper (4) is coupled to a rotary body and rotates around a rotary shaft together with the rotary body, and the swing rod mounting seat(1) is provided on a circumference on which the stopper (4) rotates around the rotary shaft. The invention has the characteristics of simple and reliable structure, small space occupation and convenient installation. The adaptability of the structure size can be applied to the range of about + / -190 degrees, and the weight of a rotary device is strictly limited, such as space two-dimensional turntables.
Description
technical field [0001] The invention relates to a limit device for a rotary mechanism, in particular to a single-point rotary limit mechanism. Background technique [0002] Most rotary shafting systems can rotate 360° infinitely. Due to specific requirements or limitations in actual work, for example, the azimuth axis of the space two-dimensional turntable is equipped with cables, which cannot achieve infinite rotation, and its rotation range must be limited. [0003] In order to ensure the full coverage of the angle, the movement stroke needs to be greater than ±180°. Now the common structural form is the structure of the limit impact block and two sets of limit pendulum blocks. However, for the state of no gravity in the space, the pendulum block can swing freely in the space, which is reliable. The performance is insufficient, and the two sets of limit pendulum blocks do not meet the requirements of lightweight space. Contents of the invention [0004] Aiming at the d...
