DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example 1: Figures 1 to 5 The portable folding arm guard shown includes a shield 1, which includes an outer shield 11 and an inner shield 12. When the shield 1 is unfolded, the outer shield 11 and the inner shield 12 are fixedly connected and on the same plane, and the shield 1 can be used as a normal shield; when the shield 1 needs to be folded, the inner shield 12 can be turned inward around the connection point with the outer shield 11 toward the outer shield 11 until it overlaps with the outer shield 11. Similarly, the outer shield 11 can be turned inward around the connection point with the inner shield 12 toward the inner shield 12 until it overlaps with the inner shield 12. When the outer shield 11 and the inner shield 12 overlap, the shield 1 is completely folded. The folded shield 1 greatly reduces the occupied area and can be placed in a storage bag on the belt like other equipment, making it easy to carry.

[0030] In the embodiment 2, the outer shield 11 and the inner shield 12 are fixedly connected with the side walls 3 on both sides, preferably integrally connected, and the outer shield 11 and the inner shield 12 are connected through the side walls 3. The connecting ears 31 are arranged at the side walls 3 of the outer shield 11 and the inner shield 12. That is, the side walls 3 of the outer shield 11 and the inner shield 12 extend in the opposite direction of the two to form the connecting ears 31. The connecting ears 31 on the side walls 3 of the outer shield 11 and the inner shield 12 are connected one by one, and the two connecting ears 31 on each side are fixedly connected through two connecting shafts. One of the two connecting shafts on each side can be pulled out from the connecting ear 31. When the outer shield 11 and the inner shield 12 are in the unfolded state, the two connecting shafts on each side of the shield 1 are inserted into the corresponding connecting ears 31 at the same time. The connecting ears 31 on each side are connected through the two connecting shafts, which can ensure the stability of the connection between the outer shield 11 and the inner shield 12 when the shield 1 is unfolded. When the shield 1 needs to be folded, one of the connecting shafts on each side is pulled out from the corresponding connecting ear 31. At this time, the connecting ears 31 on each side are connected through one connecting shaft. The outer shield 11 and the inner shield 12 can be flipped around the connecting shaft to realize the folding of the shield 1. The shield 1 is convenient to carry. By arranging the connecting ears 31, the shield 1 can be opened and closed by connecting or separating the connecting shaft and the connecting ear 31, without the need to increase other devices, which can reduce the overall weight of the shield 1.

[0031] Further, the width of the outer shield 11 is 14 cm, which is convenient for the shield 1 to be assembled on any arm. The width of the outer shield 11 is greater than the width of the inner shield 12. The connecting ears 31 on both sides of the inner shield 12 are between the connecting ears 31 on both sides of the outer shield 11. When the shield 1 is folded, the inner shield 12 is put into the outer shield 11 to avoid increasing the thickness of the shield 1 after folding, which ensures the minimization of the occupied area of the shield 1 after folding. The side walls 3 of the outer shield 11 and the inner shield 12 are perpendicular to the shield surface, which is more convenient for the folding of the shield 1. The height of the side wall 3 ranges from 3 cm to 5 cm, which is convenient for the stable fixation of the shield 1 on the arm to avoid the deviation of the shield 1 during use. The thickness of the side wall 3 ranges from 1 mm to 3 mm, which can avoid excessive thickness and excessive weight of the shield 1, and can ensure the quality of the side wall 3 itself.

[0032] Further, the two connecting shafts on both sides of the shield 1 are arranged vertically, one of the two connecting shafts on each side is selected with a rivet 32, and the other connecting shaft is selected with a pull ring self-locking plunger 33. The pull ring self-locking plunger 33 includes a cylindrical sleeve 331, a plunger 332 clamped in the sleeve 331, a spring 333 sleeved on the plunger 332 and clamped between the plunger 332 and the sleeve 331, a pull ring 334 fixedly connected with the plunger 332, and the front end of the plunger 332 and the pull ring 334 are located at the front and rear ends of the sleeve 331 respectively. Pulling the pull ring 334 controls the movement of the plunger 332 to realize on-off control. The rivet 32 passes through the first through hole 35 of the connecting lug 31 of the inner shield 12 and the outer shield 11 in turn, that is, the corresponding positions on the connecting lug 31 of the outer shield 11 and the inner shield 12 are respectively provided with the first through hole 35, the front end of the rivet 32 passes through the first through hole 35 of the inner shield 12 and the first through hole 35 of the outer shield 11 in turn, and is fixedly connected with the screw cap. The pull ring self-locking plunger 33 passes through the second through hole 36 in the connecting lug 31 of the inner shield 12 and the outer shield 11, that is, the corresponding positions on the connecting lug 31 of the outer shield 11 and the inner shield 12 are respectively provided with the second through hole 36, the front end of the pull ring self-locking plunger 33 passes through the second through hole 36 of the inner shield 12 and the second through hole 36 of the outer shield 11 in turn, the pull ring self-locking plunger 33 is fixed on the inner side of the connecting lug 31 of the inner shield 12, and the pull ring 334 thereof is located in the inner side of the shield 1. Pulling the pull ring 334 of the pull ring self-locking plunger 33, the front end of the pull ring self-locking plunger 33 retracts inward, leaving the second through hole 36 of the outer shield 11, and the outer shield 11 and the inner shield 12 can be turned around the rivet 32.

[0033] When the shield 1 is in the unfolded state, the front end of the plunger 332 protrudes out of the sleeve 331 under the action of the spring 333 and extends into the second through hole 36 of the outer shield 11. At this time, the pull ring is used in cooperation with the rivet 32 in the connecting lug 31 of the inner shield 12 and the outer shield 11 to fix the shield 1 in the unfolded state, and the shield 1 becomes a normal shield. When the shield 1 needs to be folded, the pull ring 334 is pulled away from the front end of the plunger 332, the pull ring 334 drives the front end of the plunger 332 to move away from the second through hole 36 of the outer shield 11, and the spring 333 is compressed by the card 335. At this time, the outer shield 11 and the inner shield 12 are connected only by the rivet 32 as the connecting shaft, so that the outer shield 11 and the inner shield 12 can be turned around the rivet 32 to realize the folding of the shield 1. The folded shield 1 can be put into the waistband storage bag. At the same time, since the front end of the plunger 332 is away from the second through hole 36 of the outer shield 11, after the relative rotation of the outer shield 11 and the inner shield 12 around the rivet 32, the front end of the plunger 332 is no longer opposite to the second through hole 36. Therefore, at this time, the pull ring 334 is loosened, and the front end of the plunger 332 abuts against the inner side of the connecting lug 31 of the outer shield 11, and will not extend into the second through hole 36. Only when the outer shield 11 and the inner shield 12 are pried apart to an included angle of 180°, the front end of the plunger 332 will align with the second through hole 36 and extend into the second through hole 36. Therefore, when the shield 1 needs to be unfolded, the front end of the pull ring self-locking plunger 33 can automatically extend into the second through hole 36 when the outer shield 11 and the inner shield 12 are pried apart to an included angle of 180°. Therefore, by using the pull ring self-locking plunger 33, the shield 1 can be completely unfolded in one step by prying apart the outer shield 11 and the inner shield 12 without any other action. When the shield 1 is completely unfolded, the outer shield 11 and the inner shield 12 are fixed by the two connecting shafts of the rivet 32 and the pull ring self-locking plunger 33, and are used as a normal shield. When it needs to be stored, the pull ring 334 is pulled, the front end of the pull ring self-locking plunger 33 is retracted into the sleeve 331 and kept away from the second through hole 36, until the outer shield 11 and the inner shield 12 are completely unfolded again and are folded inward to be put into the waistband storage bag.

[0034] In example 3, the shield is made of metal or organic glass, such as steel plate or acrylic plate. The steel plate has the advantages of good hardness, not easy to deform and good protection effect. The acrylic plate has the characteristics of high transparency, not easy to break and good plasticity. The middle part of the shield 1 is fixed with a protective sponge 2, which is pasted in the shield 1. The protective sponge 2 is used as a protective device for the contact surface between the shield 1 and the user, which can protect the user and avoid injury to the user's arm due to the reaction force during the fight.

[0035] Preferably, the protective sponge 2 of the outer shield 11 and the inner shield 12 is respectively fixed with a strap 21 through which the arm and the palm can pass, and the length of the strap 21 is adjustable. In use, after the shield 1 is unfolded and fixed, the shield 1 is fixed on the back of the hand, that is, the two straps 21 are respectively bound on the palm and the arm, so that the shield 1 is directly fixed on the back of the hand without the need to hold, the palm can hold other police weapons, and the shield 1 can be used in cooperation with other equipment to improve the use efficiency. Moreover, since the length of the strap 21 is adjustable, the tightness of the strap 21 can be adjusted in use to adapt to the use of personnel with different arm and palm sizes. In addition, since the strap 21 and the protective sponge 2 are soft, and the shield 1 is provided with the side wall 3 on both sides, after the shield 1 is folded, a certain space is left between the outer shield 11 and the inner shield 12, the strap 21 and the protective sponge 2 can be completely inserted between the outer shield 11 and the inner shield 12, and the normal folding of the shield 1 will not be affected, so that the shield 1 can be smoothly folded. Specifically, the strap 21 is selected to be a magic tape, the magic tape is fixedly connected with the shield 1 through a screw, each strap 21 includes a hook surface and a fuzzy surface, and the fixed ends of the hook surface and the fuzzy surface are respectively fixed in the shield 1 on both sides. The screw passes through the fixed ends of the strap 21, the protective sponge 2 and the shield surface in sequence to fixedly connect the strap 21 with the shield 1.

[0036] In example 5, the length of the shield 1 when folded is 20 cm, which is very convenient to put into the storage bag on the waistband for carrying, and the length of the shield 1 when unfolded is 36 cm, which can be used as a normal shield. In addition, when the shield 1 is unfolded, the connection position between the outer shield 11 and the inner shield 12 is partially overlapped, which improves the stability of the shield 1 when unfolded and used, and avoids that the outer shield 11 and the inner shield 12 will be turned outward.

[0037] The above examples only express the specific embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
