[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-Figure 4 As shown, the rotating column positioning structure of the mobile DR includes a positioning seat 1, a rotating column fixing plate 2, a positioning pin shaft 3 and a positioning wheel 6. The rotating column fixing plate 2 is installed on the rotating circle of the slewing bearing 7, the fixing circle of the slewing bearing 7 is connected to the chassis 8, the rotating column fixing plate 2 is provided with a positioning notch, the positioning seat 1 is installed on the chassis 8, and the positioning pin shaft 3 is vertically floatingly installed on the positioning seat 1. In this embodiment, the positioning pin shaft 3 is vertically floatingly installed on the positioning seat 1, which adopts the existing technology; there is an elastic member 5 between the positioning pin shaft 3 and the positioning seat 1, and the positioning wheel 6 is installed on the positioning pin shaft 3, and the positioning wheel 6 can be inserted into the positioning notch under the action of the elastic member 5.

[0020] A positioning pin baffle 4 matched with the positioning pin 3 is also installed on the positioning seat 1. With this structure, the installation and removal of the positioning pin 3 can be facilitated.

[0021] There are two elastic members 5 , which are respectively arranged at the upper and lower ends of the positioning pin shaft 3 , and the positioning wheel 6 is arranged at the middle of the positioning pin shaft 3 .

[0022] The positioning wheel 6 is a bearing.

[0023] The elastic member 5 is a spring, a gas spring or an elastic sheet. In the present embodiment, the elastic member 5 is a spring. Of course, other elastic compression materials can be used to achieve the same effect.

[0024] The locating seat 1 and the slewing bearing 7 are both installed on the chassis 8, the locating pin 3 and the locating wheel 6 are assembled together, the two elastic members 5 are installed in the cylindrical slot of the locating seat 1, and then the locating pin 3 and the locating wheel 6 are installed on the locating seat 1, and finally the locating pin baffle 4 is fixed; the rotating column fixing plate 2 is installed on the slewing bearing 7, and can make a rotary circular motion with the slewing bearing 7; the rotating column is fixed on the rotating column fixing plate 2, and can make a rotary circular motion with the slewing bearing 7.

[0025] In the initial state, the positioning wheel 6 is just stuck in the positioning notch of the rotating column fixing plate 2. At this time, the column is in the initial positioning state. When the column needs to be rotated to other angles, the rotating column is pushed. Under the action of external force, the positioning pin shaft 3 will bring the positioning wheel 6 to move inward along the compression direction of the spring part. At this time, the positioning wheel 6 will leave the positioning notch of the rotating column fixing plate 2. When the rotating column rotates one circle or returns to the initial position in the opposite direction of the initial movement, the positioning wheel 6 will be re-stuck in the positioning notch of the rotating column fixing plate 2 under the elastic force of the spring part, and a collision sound of the locking will also be emitted, and the rotating column returns to the initial position.

[0026] The positioning structure fully utilizes the characteristics of the spring member to automatically return to the initial positioning position and release the positioning state, which is more convenient to operate. At the same time, the structure has fewer components, occupies less space, and is more convenient to install, disassemble and maintain later.

[0027] The positioning structure is applied to mobile DR and can also be applied to mobile equipment with a rotating column structure.

[0028] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
