[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-Figure 3 The utility model proposes a rotation and folding limit mechanism, including a first main body 1 and a second main body 2. The first main body 1 and the second main body 2 can be two parts of the same shape or two parts of different shapes. The first main body 1 is provided with a rotation groove 11 and an elastic abutment mechanism 12. The elastic abutment mechanism 12 is located on one side of the rotation groove 11. The second main body 2 is provided with a rotation boss 21. The rotation boss 21 is accommodated in the rotation groove 11 and forms a rotation connection with the rotation groove 11. One end of the elastic abutment mechanism 12 extends into the rotation groove 11 and forms an elastic abutment with one side of the rotation boss 21.

[0026] In this embodiment, the first body 1 and the second body 2 are rotatably connected by a rotatable connection method of the rotating groove 11 and the rotating boss 21, and then the rotating boss 21 is pressed sideways by an elastic abutment method formed by the elastic abutment mechanism 12 and one side of the rotating boss 21, that is, a pressing force is applied to one side of the rotating boss 21, so that the first body 1 can limit the second body 2 when rotating relative to the second body 2, that is, no matter what angle the second body 2 is rotated to, it can be stopped by the pressing force of the elastic abutment mechanism 12, so that the second body 2 can stay at any angle after rotation after being rotated and folded, so as to facilitate subsequent use;

[0027] In summary, the rotation and folding limiting mechanism can effectively limit the rotational connection of the two components, so that one of the components can stay at any angle after rotation and folding, which is convenient for subsequent use.

[0028] In this embodiment, the elastic abutment mechanism 12 includes a fixed shell 121, an elastic member 122, and an abutment member 123. The abutment member 123 is slidably connected to the fixed shell 121, the abutment member 123 faces the rotating groove 11, the elastic member 122 is accommodated in the fixed shell 121, one end of the elastic member 122 abuts against the rear end of the abutment member 123, the other end of the elastic member 122 abuts against the fixed shell 121, and the front end of the abutment member 123 abuts against one side of the rotating boss 21; when the rotating boss 21 is accommodated in the rotating groove 11 and rotates, the abutment member 123 elastically abuts against one side of the rotating boss 21 through the elastic force of the elastic member 122, that is, a pressing force is applied, and when the rotating boss 21 rotates, the abutment member 123 slides relative to the side of the rotating boss 21, so that the rotating boss 21 can be maintained at any rotation position.

[0029] In this embodiment, a sliding groove 1211 is provided in the fixed shell 121, and the elastic member 122 and the abutting member 123 are both accommodated in the sliding groove 1211, and the abutting member 123 is slidably connected to the groove wall of the sliding groove 1211; when installing the abutting member 123, the elastic member 122 is first placed in the sliding groove 1211, and then the abutting member 123 is pressed toward the sliding groove 1211, so that the abutting member 123 enters the sliding groove 1211, and when the abutting member 123 is pressed in, the rotating boss 21 is installed in the rotating groove 11.

[0030] In this embodiment, the sliding groove 1211 is connected and communicated with the rotating groove 11 , so that the abutting member 123 can directly abut against the side surface of the rotating boss 21 when extending.

[0031] In this embodiment, the sliding groove 1211 is perpendicular to the tangent line of the rotating groove 11 , so that the pressing force of the abutment member 123 on the rotating boss 21 is the greatest.

[0032] In this embodiment, the elastic member 122 is a coil spring, which can be directly placed in the sliding groove 1211 .

[0033] In this embodiment, the abutment member 123 is a ball bearing, which has a low cost and is easy to install and abut.

[0034] In this embodiment, a plurality of receiving grooves 211 are provided on the outer peripheral side of the rotating boss 21, and one end of the elastic abutment mechanism 12 abuts against the inner wall of one of the receiving grooves 211. When the abutment member 123 abuts against the rotating boss 21, in order to increase the stability during the abutment, the receiving groove 211 is provided as an insertion slot for the abutment member 123, so that the second body 2 can stay more firmly at any angle after rotation under the action of the receiving groove 211 after being rotated and folded, and there is a sense of jamming during the rotation process, so as to enhance the user's rotation experience.

[0035] In this embodiment, the plurality of storage grooves 211 are evenly distributed circumferentially, and the even distribution makes the click feeling during rotation continuous, which is convenient for the user to stay at any rotation angle.

[0036] In this embodiment, an arcuate wall 2111 is provided in the receiving groove 211, and one end of the elastic abutment mechanism 12 abuts against the arcuate wall 2111. The arcuate wall 2111 is provided to facilitate the abutment member 123 to be separated from the receiving groove 211 by relying on the rotational force when the second body 2 rotates.

[0037] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
