[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a riot shield that can be quickly assembled, including a riot shield 1. Two sets of mounting brackets 2 are fixedly welded to one side of the riot shield 1. The mounting brackets 2 have lifting grooves 3 inside, and connecting grooves 13 communicating with the lifting grooves 3 are opened on both sides of the mounting brackets 2. Mounting blocks 4 are slidably connected inside the lifting grooves 3. A first threaded rod 5 is threadedly installed inside one mounting block 4. A mounting plate 7 is rotatably installed at the tail of the first threaded rod 5. A second threaded rod 6 is slidably connected inside the other mounting block 4. The first threaded rod 5 and the second threaded rod 6 are slidably installed inside the connecting grooves 13. The mounting plate 7 is fixedly welded to one end of the second threaded rod 6. A locking tooth 8 is fixedly welded to the other side of the mounting plate 7. Fixing teeth that cooperate with the locking teeth 8 are fixedly welded to both sides of the riot shield 1. 9. By inserting the mounting block 4 into the lifting groove 3, and inserting the first threaded rod 5 and the second threaded rod 6 into the connecting groove 13, when the mounting block 4 is installed to a suitable height, by rotating the first threaded rod 5, the mounting plate 7 is moved towards the fixing tooth 9, so that the fixing tooth 9 and the locking tooth 8 mesh, thereby fixing the position of the mounting block 4. A connecting plate 10 is fixedly welded between the two mounting plates 7. Two sets of mounting cylinders 11 are fixedly welded to one side of the connecting plate 10. A limiting ring 12 is slidably installed inside the mounting cylinder 11. After the mounting block 4 is installed, one set of limiting rings 12 is installed at the elbow joint, and the other set of limiting rings 12 is installed at the palm, thereby achieving personalized installation of the limiting rings 12. By sliding the limiting rings 12 along the mounting cylinder 11, the limiting rings 12 clamp the arm, ensuring that the riot shield 1 is held firmly.

[0021] The mounting bracket 2 has two sets of embedding slots 15 inside. Two sets of embedding plates 24 are fixedly welded to the rear side of the mounting plate 7. The embedding plates 24 are slidably installed inside the embedding slots 15. The length of the embedding plates 24 is longer than the distance between the fixing teeth 9 and the locking teeth 8, ensuring that the mounting plate 7 cannot rotate when the first threaded rod 5 rotates. Several sets of position holes 16 are opened on the outer side of the limiting ring 12. A locking rod 17 that matches the position hole 16 is slidably installed inside one end of the mounting cylinder 11. The locking rod 17 is inserted into the corresponding position hole 16 to fix the extension length of the limiting ring 12. A fixing plate 18 is fixedly welded to one end of the locking rod 17. A spring 19 is fixedly welded between the fixing plate 18 and the mounting cylinder 11. The spring 19 is sleeved on the outer side of the locking rod 17. When the spring 19 is not elastic, the locking rod 17 can be inserted into the position hole 16. The fixing plate 18 drives the locking rod 17. When the limiting ring 12 moves and the position hole 16 is aligned with the locking rod 17, the spring 19 pulls the locking rod 17, allowing the locking rod 17 to automatically insert into the position hole 16. A fixing nut 14 is installed on the outer thread of the second threaded rod 6. By rotating the fixing nut 14, the fixing nut 14 presses against the outer side of the mounting bracket 2, ensuring that the locking tooth 8 on the other side does not disengage from the fixing tooth 9. A rotating shaft 20 is rotatably connected to the upper side of the mounting bracket 2. A rotating plate 21 is fixedly welded to the other end of the rotating shaft 20. A third threaded rod 22 is installed on the inner thread of the rotating plate 21. A positioning hole 23 is opened on the upper part of the mounting bracket 2 to cooperate with the third threaded rod 22. By rotating the rotating plate 21 to the horizontal direction and rotating the third threaded rod 22, the third threaded rod 22 is inserted into the positioning hole 23, ensuring that the upper two sides of the mounting bracket 2 are fixed and preventing the inner mounting bracket 2 from deforming.

[0022] Working principle: When in use, the mounting block 4 is inserted into the lifting groove 3, and the first threaded rod 5 and the second threaded rod 6 are inserted into the connecting groove 13. When the mounting block 4 is installed at a suitable height, the first threaded rod 5 is rotated to drive the mounting plate 7 to move towards the fixing tooth 9, so that the fixing tooth 9 and the locking tooth 8 mesh, thereby fixing the position of the mounting block 4. After the mounting block 4 is installed, a set of limiting rings 12 are installed at the elbow joint, and the other limiting ring 12 is installed at the palm, realizing the personalized installation of the limiting rings 12. By sliding the limiting rings 12 along the mounting cylinder 11, the spring 19 pulls the locking rod 17, which can automatically insert the locking rod 17 into the position hole 16, so that the limiting rings 12 clamp the arm and ensure that the riot shield 1 is held firmly.
