DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figure 1-9The utility model provides an embodiment: a PC shield with good protective performance, including a protective mechanism 1, the protective mechanism 1 includes a shield body 101, two folding plates 102, two rotating shafts 104, two limit blocks 110 and two limit rods 111, the two folding plates 102 are respectively rotatably arranged on both sides of the shield body 101 and are respectively fixedly sleeved on the outer walls of the two rotating shafts 104, the center of both sides of the rear end surface of the shield body 101 is provided with folding grooves 103 at the upper and lower ends, the center of both sides of the upper end surface of the shield body 101 is provided with movable grooves 105 at the rear end, the two rotating shafts 104 are respectively rotatably embedded in the two folding grooves 103 located on the same side at the upper and lower ends of the two folding grooves 103, and the upper end surfaces of the two rotating shafts 104 are fixedly provided with The limiting ring 106, the two limiting rings 106 are provided with a limiting groove 107 at the center of the upper end surface, the two movable grooves 105 are fixedly provided with a fixed plate 108 on the upper end surface, the two limiting blocks 110 are respectively slidably set in the two fixed plates 108, the two limiting rods 111 are respectively fixedly set at the centers of the upper and lower end surfaces of the inner walls of the two fixed plates 108 on both sides and slide through the two limiting blocks 110 respectively, the two limiting blocks 110 are fixedly provided with a pull rod 109 at the center of the upper end surface, the two fixing plates 108 are fixedly provided with a spring 112 at the center of the upper end surface of the inner wall of the two fixing plates 108 on both sides, the other ends of the two springs 112 are respectively fixedly connected to the opposite side of the upper end surface of the two limiting blocks 110, and the two limiting blocks 110 are respectively movably clamped in the two limiting grooves 107.
[0030] Specifically, the protective mechanism 1 facilitates the rapid and effective expansion of the protective area, improving the shield's multi-directional coverage, enabling the shield body 101 to provide reliable protection over a wider range, and enhancing the user's safety in complex protection scenarios. The folding plate 102 expands the protective area of the shield body 101. When in use, the folding plate 102 can be unfolded to a wider area, providing more comprehensive protection for the user; when not in use, it can be folded and stored for easy carrying and storage.
[0031] When the protection area needs to be expanded, the two pull rods 109 are pulled to drive the two limit blocks 110 to retract and disengage from the limit slots 107 on the opposite side, and then the two folding plates 102 are flipped by rotating the two rotating shafts 104, so that the folding angles of the two folding plates 102 can be adjusted. When the required protection angle is adjusted, the two pull rods 109 are released, so that the two limit blocks 110 are movably connected to the limit slots 107 under the elastic reset action of the springs 112, and then the rotation angle of the rotating shaft 104 can be limited and fixed, thereby realizing the limit fixation of the protection angle of the two folding plates 102; the two limit rods 111 are conducive to improving the stability of the limit blocks 110 when sliding.
[0032] Reference Figure 3-5An adjustment mechanism 2 is fixedly arranged at the center of the rear end face of the protective mechanism 1. The adjustment mechanism 2 includes an adjustment plate 201, a buffer plate 202 and a bidirectional threaded rod 204. The buffer plate 202 is fixedly arranged on the front end face of the adjustment plate 201. Adjustment grooves 203 are opened on both sides of the center of the rear end face of the adjustment plate 201. The bidirectional threaded rod 204 is rotatably arranged at the center of the opposite side of the inner wall of the two adjustment grooves 203 and the threads pass through the two handles 205.
[0033] Specifically, the adjustment mechanism 2 facilitates flexible adjustment of the support position according to the arm length of different users, making it easy to use. By rotating the bidirectional threaded rod 204 to drive the two handles 205 to move relative to or apart, the distance between the two handles 205 can be adjusted, thereby flexibly adjusting the support point position. It can be accurately adjusted according to the arm length of different users, so that different users can adjust the shield support point to the most suitable position, effectively improving the comfort of holding the handles 205 and the flexibility of operation, thereby improving the practicality and flexibility of the shield.
[0034] Working principle: When in use, first pull the two pull rods 109 to drive the two limit blocks 110 to retract and disengage from the limit slots 107 on the opposite side, and then rotate the two rotating shafts 104 to drive the two folding plates 102 to flip, so as to adjust the folding angle of the two folding plates 102. When the required protection angle is adjusted, the two pull rods 109 are released, so that the two limit blocks 110 are movably engaged in the limit slots 107 under the elastic reset action of the springs 112, so that the protection angle of the two folding plates 102 can be limited and fixed;
[0035] Secondly, by rotating the bidirectional threaded rod 204 to drive the two handles 205 to move relative to or apart, the distance between the two handles 205 can be adjusted, and the support point position can be accurately and flexibly adjusted according to the arm length of different users; when not in use, it can be folded and stored for easy carrying and storage.
