Description

Technical Field

[0001] The utility model belongs to the technical field of protective gear, in particular to a connection structure and a full-cover bulletproof helmet. Background Art

[0002] The trend of the growing military power of countries around the world is inevitable. At the same time, the power of military weapons on the battlefield is also increasing. These weapons will produce a large number of explosive fragments during the explosion process, causing serious trauma to the soldiers' heads and faces. However, traditional bulletproof helmets can only protect the upper part of the head. The head protection area is insufficient, and the eyes and jaw are still not within the protection range. Therefore, they will still be directly injured by explosive fragments, warheads or shrapnel on the battlefield. In the face of the above problems, it is urgent to install bulletproof masks and goggles on bulletproof helmets to achieve protection for the face, eyes and jaw. However, at this stage, there is still a lack of all-inclusive, integrated bulletproof combat helmets that can fully match masks and glasses. In addition, all-inclusive bulletproof helmets not only need to achieve all-round head protection, but also need to be able to be quickly disassembled and assembled to meet tactical actions such as holding a gun and shooting, and even need to be operated with one hand to improve combat efficiency during combat.

[0003] At present, relevant technical personnel have done some research in this field. Patent CN114383469A introduces a face mask for bulletproof protective helmets. This technology plays an effective anti-impact effect through the action of the face mask plate and the debris protection lip. The mask is fixedly connected to the helmet body and rotated longitudinally with the help of double-sided bearings, but the installation and removal of the bulletproof mask need to be completed with the help of corresponding tools, and does not have the quick installation and quick removal functions of the bulletproof mask of the utility model patent. Patent CN112869283A introduces a double-layer mask protective helmet and its manufacturing method. The mask adopts a double-layer structure of upper and lower pieces. The upper mask is used to protect the front of the head, and the lower mask protects the lower jaw. Although this design can obtain more protection area, it is necessary to disassemble and assemble the inner and outer masks, which limits its application in the field of single-soldier combat. Patent CN108168372A introduces a bulletproof helmet and a mask thereof. The technology designs a mounting plate and a mounting bracket, which are arranged on both sides of the bulletproof mask. The buckles on the mounting plates are used to fix both sides of the mask at the same time. The mask requires both hands to operate the mounting plates on both sides at the same time, which affects the combat efficiency of individual combat personnel and limits its application in the field of individual combat. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the mask needs both hands to operate the mounting plates on both sides at the same time, which affects the combat efficiency of individual combat personnel and limits its application in the field of individual combat, and to provide a connection structure and a full-enclosed bulletproof helmet.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0008] A second connecting portion, comprising a second magnetic member and a limiting groove arranged on a second connecting surface of the second connecting portion;

[0009] The first connection surface and the second connection surface are arranged opposite to each other and can be adsorbed and attached to each other under the action of the first magnetic member and the second magnetic member;

[0010] When the first connection surface and the second connection surface are fitted and connected, the limiting groove is located on the sliding path of the active buckle, and the active buckle can slide into the limiting groove and be limited in a direction perpendicular to the first connection surface.

[0011] In this solution, the above structure is adopted, and the connection structure includes a first connection part and a second connection part that can be detached from each other. The first connection part and the second connection part can be fixed to the two parts to be connected respectively. The two parts to be connected are assembled together through the cooperation of the first connection part and the second connection part. When it is necessary to remove, it is only necessary to operate the connection structure to make the first connection part and the second connection part detach. The first connection part and the second connection part respectively include a first connection surface and a second connection surface that are arranged opposite to each other. The first connection surface and the second connection surface are both provided with a first magnetic part and a second magnetic part that attract each other and can be spontaneously adsorbed when the two are close. There is a movable buckle that can slide on the first connection surface, and there is a corresponding limiting groove on the second connection surface. When the first connection surface and the second connection surface are mutually adsorbed and fitted, the movable buckle can slide into the limiting groove and limit the relative movement of the first connection part and the second connection part in a direction perpendicular to the first connection surface and the second connection surface, so as to prevent the two from being separated and fixed. When it is necessary to remove, the two can be separated by only needing the movable buckle to escape from the limiting groove. This structure enables the assembly to be spontaneously aligned and moved to a certain extent through the magnetic part, making it more convenient to assemble and disassemble.

[0012] Preferably, the driving member comprises a third magnetic member, and the third magnetic member can drive the movable buckle to slide into the limiting groove under the action of the second magnetic member.

[0013] In this solution, the above structure is adopted, and the movement of the active buckle is also realized by the magnetic part, so that it can be driven to move by the second magnetic part during the assembly process. In this way, during assembly, the first connection part and the second connection part attract each other under the action of the first magnetic part and the second magnetic part, and the active buckle can be moved to the limit groove to complete the fixation under the interaction of the third magnetic part and the second magnetic part while completing the self-alignment and adsorption. The whole process is completed completely spontaneously. The user only needs to bring the first connection part and the second connection part close together when assembly is required to quickly and accurately complete the connection assembly, which greatly improves the convenience of operation and assembly efficiency.

[0023] In this solution, the above structure is adopted, and the magnetic part is set at one end away from the rotating seat, and the torque principle is used to make the connection strength higher. In addition, the distance between the two magnetic parts will change most obviously with the rotation angle when they are set at a position away from the rotation center.

When the first connecting surface and the second connecting surface are fitted and connected, the positioning connecting piece and the positioning fitting piece cooperate with each other and limit the relative movement of the first connecting part and the second connecting part in the movement direction of the movable buckle.

[0027] In this solution, by adopting the above structure, the positioning connector can further prevent the first connection part and the second connection part from moving relative to each other in the direction of movement of the movable buckle, thereby avoiding relative movement between the two and causing them to separate from each other, thereby improving the stability of the connection.

[0028] Preferably, the first magnetic component and / or the second magnetic component is a neodymium iron boron magnet.

The helmet is fixed to the second connecting part, and the mask is fixed to the first connecting part. The soldier can hold the first connecting part with one hand and bring it close to the corresponding first connecting part. Under the action of magnetic attraction, the first connecting part and the second connecting part will automatically fit together to complete the assembly, greatly reducing the operation and time required for assembly and disassembly, so that the soldier can disassemble and install the bulletproof mask with one hand, providing the soldier with more action possibilities, which is particularly important and can protect the safety of the soldier at critical moments.

[0035] In this solution, the above structure is adopted, and the helmet body is roughly a hemispherical shell structure. When in use, it is worn on the head, mainly protecting the upper and rear parts of the head. The mask structure is roughly in the shape of a quarter spherical shell, mainly protecting the face from the nasal bone to the lower forehead and the mandibular bones on both sides.

There is a movable buckle that can slide on the first connection surface, and there is a corresponding limiting groove on the second connection surface. When the first connection surface and the second connection surface are mutually adsorbed and fitted, the movable buckle can slide into the limiting groove and limit the relative movement of the first connection part and the second connection part in a direction perpendicular to the first connection surface and the second connection surface, so as to prevent the two from being separated and fixed.

[0082] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0083] Embodiment 1

[0084] like Figure 1 , 2 As shown, this embodiment provides a full-cover bulletproof helmet 2, which includes a helmet 2, a mask 3, a connection structure 1 for detachable connection between the helmet 2 and the mask 3, and goggles 4. The helmet 2 and the mask 3 are connected by a special connection structure 1 provided by the utility model. The connection structure 1 can greatly reduce the operation and time required for assembly and disassembly, so that soldiers can disassemble and install the bulletproof mask 3 with one hand, provide soldiers with more action possibilities, and protect soldiers' safety at critical moments.

[0085] like Figures 3 to 9 As shown, the connection structure 1 of this embodiment includes a first connection part 11 and a second connection part 12 on the helmet 2 and the mask 3 respectively. Among them, the first connection part 11 includes a first magnetic member 118 arranged on the first connection surface 110 of the first connection part 11 and an active buckle 115 that can slide back and forth along a straight line direction parallel to the plane where the first connection surface 110 is located under the action of the driving member. The second connection part 12 includes a second magnetic member 124 and a limiting groove 122 arranged on the second connection surface 120 of the second connection part 12. The first connection surface 110 and the second connection surface 120 are arranged opposite to each other and can be adsorbed and attached under the action of the first magnetic member 118 and the second magnetic member 124. When the first connection surface 110 and the second connection surface 120 are attached and connected, the limiting groove 122 is located on the sliding path of the active buckle 115, and the active buckle 115 can slide into the limiting groove 122 and be limited in a direction perpendicular to the first connection surface 110.

[0086] The connection structure 1 includes a first connection part 11 and a second connection part 12 which can be detached from each other. The first connection part 11 and the second connection part 12 can be fixed to two parts to be connected respectively. In this embodiment, the first connection part 11 is fixed to the mask 3, and the second connection part 12 is fixed to the helmet 2. The helmet 2 and the mask 3 are assembled through the connection structure 1. The two parts to be connected are assembled together through the cooperation of the first connection part 11 and the second connection part 12. When they need to be disassembled, it is only necessary to operate the connection structure 1 to disengage the first connection part 11 and the second connection part 12. The first connection part 11 and the second connection part 12 respectively include a first connection surface 110 and a second connection surface 120 which are arranged opposite to each other. The first connection surface 110 and the second connection surface 120 are both provided with a first magnetic member 118 and a second magnetic member 124 which attract each other and can be spontaneously adsorbed when they are close to each other under the action of the two. The first connection surface 110 is provided with a movable buckle 115 that can slide, and the second connection surface 120 is provided with a corresponding limiting groove 122. When the first connection surface 110 and the second connection surface 120 are mutually adsorbed and attached, the movable buckle 115 can slide into the limiting groove 122 and limit the relative movement of the first connection part 11 and the second connection part 12 in a direction perpendicular to the first connection surface 110 and the second connection surface 120, so as to prevent the two from being separated and fixed. When removal is required, the two can be separated by only needing the movable buckle 115 to be removed from the limiting groove 122. This structure enables the assembly to be spontaneously aligned and moved to a certain extent through the magnetic part, making it convenient to assemble and disassemble.

[0087] like Figure 7 As shown, the driving member includes a third magnetic member 1151, and the third magnetic member 1151 can drive the movable buckle 115 to slide into the limiting groove 122 under the action of the second magnetic member 124. The movement of the movable buckle 115 is also achieved by the magnetic member, so that it can be driven to move by the second magnetic member 124 during the assembly process. In this way, during assembly, the first connecting part 11 and the second connecting part 12 are attracted to each other under the action of the first magnetic member 118 and the second magnetic member 124. At the same time, when the self-alignment and adsorption are completed, the movable buckle 115 can be moved to the limiting groove 122 to complete the fixation under the interaction of the third magnetic member 1151 and the second magnetic member 124. The whole process is completed completely spontaneously. The user only needs to bring the first connecting part 11 and the second connecting part 12 close to each other when assembly is required to quickly and accurately complete the connection assembly, which greatly improves the convenience of operation and assembly efficiency.

[0088] When fighting for a long time, the heavy weight of the helmet 2 will cause great fatigue to the soldiers. At this time, the role of quickly disassembling and installing the mask 3 with one hand will be particularly prominent. When the soldier encounters an emergency, he needs to hold the gun with one hand and wear the mask 3 with the other hand. Under the action of the connecting structure 1, the soldier can hold the first connecting part 11 on one side with one hand and move it horizontally close to the second connecting part 12 corresponding to the one side. Under the action of the magnetic attraction, the second connecting part 12 on one side will automatically fit with the first connecting part 11. At the same time, the movable buckle 115 in the first connecting part 11 is embedded in the limiting groove 122 of the second connecting part 12 under the action of the third magnetic part 1151, and enters a locked state.

[0089] The first magnetic member 118, the second magnetic member 124 and the third magnetic member 1151 are all strong magnets, preferably neodymium iron boron magnets, so that they can satisfy the function of automatic positioning and installation on the one hand, and ensure the connection strength on the other hand.

[0090] In this embodiment, Figure 5 As shown, the third magnetic member 1151 of the movable buckle 115 is a small magnet, which is arranged on the inner side of the movable buckle 115, and can be attracted by the second magnetic member 124 on the second connecting portion 12 so that the first connecting portion 11 and the second connecting portion 12 are close to each other. Figure 4 , Figure 7 When the magnetic force is applied, the entire movable buckle 115 is driven to approach the second magnetic member 124 and the movable buckle 115 is inserted into the limiting groove 122. Figure 8 shown.

[0091] In other embodiments, the third magnetic component 1151 can also be arranged to be in a repulsive relationship with the second magnetic component 124. In this case, the second magnetic component 124 needs to be arranged in the direction where the movable buckle 115 is away from the limiting groove 122. When the first connecting part 11 and the second connecting part 12 are close to each other, the repulsive force pushes the movable buckle 115 to move in the direction away from the second magnetic component 124 and enter the limiting groove 122.

[0092] In addition, in other embodiments, the magnet of the driving part may be replaced with other structures, such as a spring, or an electric movable structure, etc., so as to achieve the movement of the movable buckle 115 by other means instead of magnetic force.

[0093] When the soldier is aiming with his cheek against the ground, he needs to aim his face close to the scope, and the mask 3 will affect the sight. Under the action of the connecting structure 1, the disassembly process of the bulletproof mask 3 can be completed with one hand. First, the push switch 112 of the first connecting part 11 on one side of the helmet body is pressed, and the movable buckle 115 inside the first connecting part 11 will be released from the limiting groove 122 of the second connecting part 12. At this time, the locking state between the first connecting part 11 and the matching second connecting part 12 on this side begins to be released, and the connecting structure 1 on one side of the bulletproof mask 3 is opened, and the bulletproof mask 3 enters the unilateral buckle hanging state. Then, the push switch 112 on the other side of the bulletproof mask 3 is pressed, and the locking state between the first connecting part 11 and the second connecting part 12 on this side begins to be released. At this time, the connecting structures 1 on both sides of the bulletproof mask 3 are all released, so that the purpose of quick removal of the bulletproof mask 3 with one hand can be further achieved. If both hands act on the push switches 112 on both sides at the same time, the purpose of rapid removal of both hands can be achieved, which greatly reduces the combat load. While effectively protecting the soldier's head from being hit by stray bullets and shrapnel, it also ensures the soldier's combat efficiency, thus completing the working principle of the device.

[0094] like Figures 5 to 8 As shown, the first connection part 11 includes a first protruding part 111 protruding from the first connection surface 110, a receiving groove 114 is provided in the first protruding part 111, an active buckle 115 is arranged in the receiving groove 114 and can slide in the extension direction of the receiving groove 114, and a third magnetic member 1151 is arranged on the active buckle 115. The second connection part 12 includes a second protruding part 121 protruding from the second connection surface 120, a limiting groove 122 is arranged in the second protruding part 121, and a second magnetic member 124 is arranged in the second protruding part 121. The first magnetic member 118 is arranged at a position of the first connection surface 110 corresponding to the second protruding part 121.

[0095] In this embodiment, the first protrusion 111 and the second protrusion 121 are in an interlaced connection state when they are assembled, the openings of the receiving groove 114 and the limiting groove 122 are arranged relatively to each other, and the movable buckle 115 can be inserted into the limiting groove 122 when it extends from the receiving groove 114.

[0096] By adopting this structure with protrusions at both ends being staggered, the distance between the second magnetic component 124 and the first magnetic component 118 and the third magnetic component 1151 can be shortened to improve the effect of their magnetic action, while the first magnetic component 118 and the second magnetic component 124 can be pulled farther apart to reduce unnecessary interaction between the two and improve the connection effect.

[0097] In another embodiment, the positions of the first protrusion 111 and the second protrusion 121 may be changed to some extent, for example, the limiting groove 122 may be set at the edge of the side of the second connection part 12, and the movable buckle 115 of the first connection part 11 may protrude from the edge of the first connection part 11 and be inserted into the limiting groove 122 of the side of the second connection part 12 for fixation. Alternatively, the relationship between the first connection part 11 and the second connection part 12 and the limiting groove 122 of the movable buckle 115 may be exchanged, etc., as long as it can be ensured that the two can be limited in the direction in which they can be separated from each other after connection (i.e., the direction perpendicular to the first connection surface 110 and the second connection surface 120) to prevent them from being separated.

[0098] like Figure 5 As shown, the surface of the first connecting portion 11 is recessed inward to form a recessed portion 116, the first magnetic member 118 is disposed in the recessed portion 116, and the second protrusion 121 can partially extend into the recessed portion 116. In this embodiment, a portion of the receiving groove 114 is also in the recessed portion 116, so as to facilitate alignment with the second protrusion 121 when extending into the recessed portion 116 during assembly.

[0099] By opening a recessed portion 116 on the surface of the first connecting portion 11, the magnetic effect of the first magnetic member 118 and the second magnetic member 124 and the third magnetic member 1151 and the second magnetic member 124 can be further enhanced and the effect of the first magnetic member 118 and the third magnetic member 1151 can be reduced. Moreover, through this mutually nested and staggered effect, the connection stability between the first connecting portion 11 and the second connecting portion 12 can also be improved.

[0100] The first magnetic member 118 is disposed in the recessed portion 116 , and the second magnetic member 124 is disposed in the second protruding portion 121 . When the second protruding portion 121 extends into the recessed portion 116 , the first magnetic member 118 and the second magnetic member 124 are closest to each other and the suction force is the strongest.

[0101] like Figures 5 to 8As shown, the second connection part 12 is also provided with a positioning connector, and the first connection part 11 is provided with a positioning fitting corresponding to the positioning connector. When the first connection surface 110 and the second connection surface 120 are fitted and connected, the positioning connector and the positioning fitting cooperate with each other and limit the relative movement of the first connection part 11 and the second connection part 12 in the movement direction of the active buckle 115. In this embodiment, the positioning fitting is a horizontal groove structure arranged on the inner side of the recessed part 116, and the positioning connector is a tongue-shaped structure arranged at the outer end of the second protruding part 121 and extending horizontally. When the first connection part 11 and the second connection part 12 are assembled, the second protruding part 121 extends into the recessed part 116, and the active buckle 115 is clamped in the limiting groove 122 to limit the first connection part 11 and the second connection part 12 in the horizontal direction, and the tongue-shaped structure of the positioning connector is clamped in the groove structure of the positioning fitting to limit the first connection part 11 and the second connection part 12 in the vertical direction.

[0102] The positioning connector can further prevent the first connection portion 11 and the second connection portion 12 from moving relative to each other in the direction of movement of the movable buckle 115, thereby preventing the two from moving relative to each other and causing them to separate from each other, thereby improving the stability of the connection.

[0103] like Figure 3 As shown, it also includes a rotating seat 13, one end of the first connecting part 11 is rotatably connected to the rotating seat 13, and the first connecting part 11 can rotate and fit or separate from the second connecting part 12. By providing the rotating seat 13, during assembly and disassembly, it is only necessary to rotate the first connecting part 11 to different angles to achieve installation, which is more convenient.

[0104] The two rotating seats 13 are respectively embedded with two mounting holes 131, and the two mounting holes 131 are in parallel relative positions. The two ends of the stainless steel optical axis 132 are respectively embedded in the two mounting holes 131. Two parallel through holes 113 are set at the bottom of the first connecting part 11 to pass the stainless steel optical axis 132 through it, and the two ends are fixed to the inside of the mounting holes 131, thereby forming a rotating mechanism between the first connecting part 11 and the rotating seat 13, so as to realize the one-handed wearing and removal of the mask 3.

[0105] In this embodiment, both sides of the mask 3 and the helmet 2 are provided with the same connection structure 1, which enables the all-inclusive bulletproof helmet 2 to provide a semi-connected single-side suspension wearing strategy. In the above-mentioned equipment operation, only one side of the connection structure 1 is disassembled and assembled, that is, only one side of the connection structure 1 is fixed. Due to the rotational connection relationship between the first connection part 11 and the rotating seat 13, the mask 3 can achieve a single-side suspension state, and this state can be used in conjunction with operations such as holding a gun against the cheek to aim, communicating with external devices, eating and drinking, etc., so as to better adapt to the changing combat environment on the battlefield.

[0106] The connection structure 1 includes a fixed seat 14 and a rotating seat 13. A limiting structure 141 and two fixing holes 142 for screw installation are arranged on one side of the fixed seat 14. The rotating seat 13 extends outward and protrudes, and two transverse fixing holes 142 are arranged on the upper side. The lower surfaces of the fixed seat 14 and the rotating seat 13 are respectively fitted with the curved surfaces of the helmet body and the mask 3, and a tight structure is formed with the help of connecting screws. The connecting screws between the fixed seat 14 and the helmet body are arranged longitudinally, and the connecting screws between the rotating seat 13 and the bulletproof mask 3 are arranged transversely. At the same time, in order to adapt to the center position of the mask 3 and the angle when hanging, the screw connection line has a certain angle with the horizontal and vertical directions. A stainless steel shaft is embedded in the rotating seat 13 and is connected to the first connecting part 11 to form a rotating structure.

[0107] like Figure 7 , Figure 8 As shown, the first magnetic member 118 is arranged at one end of the first connection portion 11 away from the rotating seat 13. The magnetic member is arranged at the end away from the rotating seat 13, and the torque principle is used to make the connection strength higher. In addition, the position away from the rotation center can make the distance between the two magnetic members change most obviously with the rotation angle. Only a small rotation angle is required to make the magnetic force transmission of the magnetic member change significantly, which is convenient for installation and disassembly.

[0108] like Figures 6 to 9 As shown, the first connection portion 11 further includes a push switch 112, which is connected to an active buckle 115, and the active buckle 115 can be driven and slid by the push switch 112. Fig. 9 As shown, in this embodiment, the push switch 112 is integrally provided with the movable buckle 115, the bottom of the movable buckle 115 has a connecting structure 1 for connecting the push switch 112, and the push switch 112 is provided at the top of the first connecting portion 11 for easy operation. By providing the push switch 112, the movable buckle 115 can be conveniently operated, which is convenient for installation and removal.

[0109] like Figure 1 , Figure 2 As shown, the rear lower edge of the helmet 2 extends downward and bulges on both sides to form ear protection parts 21, and both sides of the mask 3 have convex surfaces 31 corresponding to the ear protection parts 21, the first connecting part 11 is fixed to the convex surface 31, and the second connecting part 12 is fixed to the ear protection part 21. When the first connecting part 11 is connected to the second connecting part 12, the convex surface 31 and the ear protection part 21 are fitted and closed.

[0110] The lower rear edge of the helmet 2 body is extended longitudinally to obtain a larger rear neck protection area; the ear protection areas on both sides of the helmet body are provided with larger raised surfaces 31 outwardly, which have a larger ear protection area and are more suitable for wearing combat tools inside the helmet body.

[0111] The appearance of the bulletproof mask 3 continues to use the material and curved surface of the helmet body to improve the bulletproof level of the mask 3 and the coordination between the bulletproof mask 3 and the helmet body; in addition, combined with the facial features of the human body, not only the overall protection area of ​​the mask 3 is increased, but also bulges and convex surfaces are set on the front and sides of the mask 3 to focus on strengthening the protection of the cheeks and nose bridge. In addition, the bulletproof mask 3 is thinned relative to the helmet body of the helmet 2 for easy wearing.

[0112] The second connection portion 12 is connected to the helmet 2 via a fixing seat 14 , and a side of the fixing seat 14 facing the helmet 2 has a curved surface structure corresponding to the curved surface of the surface of the helmet 2 .

[0113] like Figure 1 , Figure 2 As shown, it also includes goggles 4, the upper side shape of the goggles 4 corresponds to the lower edge of the front side of the helmet 2, the lower side shape of the goggles 4 corresponds to the upper edge of the mask 3, and the goggles 4 are arranged between the mask 3 and the helmet 2 and completely close the gap between the mask 3 and the helmet 2.

[0114] The helmet body is roughly in the shape of a hemispherical shell. When in use, it is worn on the head, mainly protecting the upper and rear parts of the head. The mask 3 is roughly in the shape of a quarter spherical shell, mainly protecting the face from the nasal bone to the lower forehead and the mandibular bones on both sides. The bulletproof goggles fill the uncovered area of ​​the face, mainly protecting the eyes and the surrounding areas, covering the head, eyes, and face in all directions to prevent non-directional injuries caused by explosion fragments on the battlefield.

[0115] like Figure 1 , Figure 2 As shown, a dried cuttlefish bracket 22 is provided on the helmet 2, and the helmet 2 is connected to the goggles 4 through a cantilevered connecting rod 41. Through the cantilevered connecting rod 41 and the dried cuttlefish bracket 22, the goggles 4 can be ensured to be flexible and movable, and the disassembly is convenient while improving the strength of the connection. The helmet 2 is the core of the all-inclusive bulletproof helmet 2, and the goggles 4 are fixed to the dried cuttlefish bracket 22 through the cantilevered connecting rod 41, and the dried cuttlefish bracket 22 is fixed to the helmet body through screws. The mask 3 is connected to the connecting structure 1 through the rotating seats 13 on both sides to be detachably connected to the helmet body.

[0116] The all-inclusive bulletproof helmet 2 of the utility model has the following effects:

[0117] (1) The design of the full-cover bulletproof helmet 2 realizes large-area protection of the head, and covers the head, eyes, and face in all directions to prevent non-directional damage caused by explosion fragments on the battlefield. At the same time, the quick-detachable full-cover bulletproof helmet 2 is designed from the helmet body, continuing the material and optimizing the structural characteristics of the helmet body, and optimizing the design of the helmet 2, mask 3, and goggles 4, which ensures the performance while giving visual consistency.

[0118] (2) For traditional all-inclusive bulletproof helmets 2, most of them adopt the rail-type disassembly and assembly of the bulletproof mask 3. When using it, both hands need to find the accurate position of the two-side rails at the same time and push them at the same time to complete the installation of the bulletproof mask 3. The operation is difficult and the operation efficiency is low. In order to improve the operation efficiency of the bulletproof helmet 2 between different wearing requirements, the bulletproof mask 3 of the above-mentioned quick-detachable all-inclusive bulletproof helmet 2 has added a quick disassembly and assembly function design. The specific operation is: pinch the first connection part 11 of the mask 3 with the thumb and middle finger of both hands, and find the corresponding position of the second connection part 12 when assembling. Under the action of the strong magnet, it automatically forms a locking structure with the first connection part 11, and the tongue-shaped structure of the press switch 112 on the first connection part 11 will be lifted, indicating that the first connection part 11 is in a locked state, and the installation operation is completed; when disassembling, the position of both hands remains unchanged, the index finger presses the tongue-shaped structure of the first connection part 11 to press the switch 112, and the thumb and middle finger flip the first connection part 11 to both sides to quickly remove the mask 3, completing the disassembly operation.

[0119] (3) The existing bulletproof mask 3 has a single wearing state, and there are only two states: synchronous locking on both sides and synchronous separation on both sides. For single-soldier combat, there are many inconveniences. Taking into account the different wearing needs of soldiers on the battlefield, the above-mentioned quick-release full-cover bulletproof helmet 2 provides a semi-connected single-sided suspension wearing strategy. In the above-mentioned equipment operation, only one side of the connecting mechanism is disassembled and assembled, that is, only one side of the connecting mechanism is fixed. Due to the rotating structure of the first connecting part 11 and the rotating seat 13, the mask 3 can achieve a single-sided suspension state, and this state can cooperate with operations such as holding a gun against the cheek to aim, communicating with external equipment, eating and drinking, so as to better adapt to the changing combat environment on the battlefield.

[0120] (4) The existing all-inclusive bulletproof helmet 2 has the problem that the bulletproof mask 3 needs to be disassembled and assembled with both hands. For individual combat personnel, the above problem greatly occupies the use space of both hands. The soldier can use the optimized quick-release assembly to disassemble and assemble the bulletproof mask 3 with one hand to adapt to the complex combat environment. Referring to the above assembly operation, the individual combat personnel can choose to fix one side connection structure 1 with one hand to form the above-mentioned single-sided hanging state, and then install the other side connection structure 1 to complete the double-sided installation; when disassembling, unlock the opposite side connection structure 1 with one hand to form a single-sided hanging state, and then unlock the same side connection structure 1 to complete the double-sided disassembly. Single-handed disassembly can maximize the soldier's operating ability on the battlefield and provide soldiers with more action possibilities. This is particularly important and can protect the safety of soldiers at critical moments.

[0121] Example 2

[0122] like Fig.10 , Fig.11As shown, the structure of this embodiment is substantially the same as that of the first embodiment, except that, in this embodiment, the driving part realizes the sliding of the movable buckle 115 through a spring. In this embodiment, a spring is provided as a power source for the movable buckle 115, and the elastic force of the spring supports the movable buckle 115 to extend. When assembly is required, the movable buckle 115 is pressed down by pressing the switch 112 for assembly or disassembly.

[0123] The driving part may be provided with only a spring without providing the third magnetic member 1151. With this solution, the switch 112 needs to be pressed manually during assembly and disassembly, which is inconvenient.

[0124] The driving part may also be provided with a spring and a third magnetic member 1151 at the same time, and the spring is used to assist the movable buckle 115 to extend or the spring is used to keep the movable buckle 115 in the receiving groove 114 during assembly to facilitate assembly and disassembly.

[0125] It should be noted that the connection structure provided by the present invention can not only be used for connecting helmets and masks, but can also be used as a connection structure for other equipment such as backpack hanging parts to achieve a corresponding quick-release effect.
