[0025] 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.

[0026] Reference Figure 1-Figure 7 , an embodiment provided by the utility model:

[0027] A foldable PC shield comprises an upper plate 1 and a lower plate 2, wherein a groove No. 1 is provided at the lower front end of the upper plate 1, a connecting rod 4 is hingedly provided between the inner walls on both sides of the groove No. 1, a torsion spring is provided at the hinge between the connecting rod 4 and the groove No. 1, a plurality of spikes 5 are fixedly provided at the front end of the connecting rod 4, a connecting rope 6 is fixedly provided at the middle of the upper end of the connecting rod 4, an extension groove is provided on the top surface of the inner side of the extension groove, a through hole 9 is provided on the inner wall on the rear side of the extension groove, a connecting rope 6 passes through the through hole 9 at the rear end and is fixedly provided with a connecting block 7, two baffles 8 are fixedly provided at the middle of the rear end of the upper plate 1, a groove No. 2 is provided at the lower upper end of the upper plate 1, a slide groove 18 is provided on the inner walls on both sides of the groove No. 2, a slider 19 is slidably provided inside the slide groove 18, a fixing plate No. 13 is hingedly provided on the opposite side of the two sliders 19, and a groove No. 3 is provided on both sides of the lower end of the fixing plate No. 13;

[0028] Two No. 2 fixing plates 15 are fixedly provided at the upper end of the lower plate 2 , and the two No. 2 fixing plates 15 are hingedly provided inside the two No. 3 grooves 14 , respectively.

[0029] Insert blocks 16 are fixedly provided on both sides of the lower end of the upper plate 1, slots 17 are opened on both sides of the upper end of the lower plate 2, handles 11 are fixedly provided on both sides of the rear end of the upper plate 1, an observation window 10 is fixedly provided on the upper front end of the upper plate 1, and return springs 20 are fixedly provided at the lower ends of the two sliders 19. The lower ends of the two return springs 20 are fixedly connected to the inner bottom surfaces of the two slide grooves 18 respectively. The two baffles 8 are provided with an inverted L-shaped structure, and the upper plate 1 and the lower plate 2 are both provided with PC material.

[0030] Specifically, the shield is provided with an upper plate 1 and a lower plate 2, which can be folded to reduce the size of the shield and facilitate carrying. The shield can be opened by providing spikes 5, so that the shield is not only used for defense, but also for thrust attacks, increasing the pressure on the enemy. The connecting rope 6 is provided, and the connecting rod 4 can be pulled up by pulling the connecting rope 6 to rotate the spikes 5 ninety degrees for use. The connecting rope 6 is connected by providing a connecting block 7. After the connecting rope 6 is pulled, the connecting block 7 is clamped on the lower side of the two blocking rods 8 to fix the connecting block 7. The observation window 10 is provided to facilitate observation of the environment. The remaining parts can be selectively covered with films or set to an opaque state to prevent the enemy from penetrating the user's body.

[0031] By providing a slide groove 18 on the inner wall of both sides of the No. 2 groove 12, the two sliders 19 slide in the slide groove 18, so that the No. 1 fixed plate 13 and the No. 2 fixed plate 15 can be pulled down with the lower plate 2 to make the insert block 16 move out of the slot 17 to fold the lower plate 2. By setting the insert block 16 and the slot 17, the opened upper plate 1 and lower plate 2 can be limited. By setting the reset spring 20, the upward force of the slider 19 can be always maintained to prevent the lower plate 2 from sliding off the upper plate 1. The shield is made of PC material. PC refers to polycarbonate material, which is widely used in law enforcement, security and military fields. Polycarbonate is an engineering plastic with high strength, good toughness and high transparency.

[0032] Working Principle: When in use, the shield can be used by pulling the connecting block 7 to drive the connecting rope 6 to pull the connecting rod 4, causing the multiple spikes 5 to rotate 90 degrees to face outward, and the connecting block 7 is clamped under the two blocking rods 8 to fix it, thus serving as an additional attack method;

[0033] Secondly, when the shield is not in use, the lower plate 2 can be moved downward relative to the upper plate 1 so that the two inserting blocks 16 are removed from the slots 17, and then the lower plate 2 can be folded upward. Folding the shield can reduce its volume and make it easier to carry.

[0034] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
