Description

Technical Field

[0001] This utility model relates to the field of security equipment technology, and more specifically, it relates to a security shield. Background Technology

[0002] Security work is an important part of ensuring social stability and protecting the lives and property of the people. It generally involves responding to sudden violent incidents in workplaces and other areas where people gather, often dealing with rioters using cold weapons. In order to meet the needs of operations that prioritize protection, security shields with both protective and suppressive capabilities are important equipment for security work and are widely used in schools, government offices, and other public places with high traffic.

[0003] Most common security shields have a simple structure, with a handle inside the shield for holding it. The handle is directly connected to the shield body. When attacked, the shield transmits the impact to the arm holding it. If the impact is large, the excessive force transmitted to the hand at once can affect the stability of the grip and may even cause injury to the shield holder's hand. Moreover, because common shields have a relatively simple structure, their grip is mostly fixed inside the shield and cannot be adjusted. While security shields are mass-produced and have a uniform structure, security personnel have different physiques, and arm lengths vary from person to person. Different personnel require different grip postures, but manufacturers cannot customize shields for security personnel. Therefore, some security personnel use shields in a relatively inconvenient posture, affecting comfort and effectiveness during combat. In addition, different combat methods sometimes require different shield holding methods, which also require different grip structures. Vertical grips and angled grips will meet the comfort of different shield holding methods, while shields with fixed structures cannot adjust the grip. Two sets of shields need to be prepared to meet different combat needs, which is inconvenient to plan. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a security shield with the following advantages:

[0018] 1. The sliding frame and sliding shell work together to provide a movable connecting structure. In conjunction with the buffer spring, they form a shock-absorbing structure. The buffer pad further absorbs the impact, so that when the shield is impacted, it is not transmitted to the arm all at once. Instead, a portion is transmitted first, and then another portion is transmitted after the buffer structure is released, reducing the impact on the arm and improving the performance.

[0019] 2. The sliding frame and handheld frame work together to provide a movable grip structure, which is controlled by the adjustment handle and adjustment screw. This allows the spacing of the grip structure at both ends of the inner side of the shield to accommodate security personnel with different arm lengths, so that security personnel of different builds can use the security shield more comfortably, improve the usage effect, and enhance combat capabilities.

[0020] 3. The mounting structure is formed by the cooperation of the mounting screw tube, mounting hole and mounting stud, so that the handle and the sliding frame can be detachably connected. By setting multiple mounting screw tubes in different positions to cooperate with the handle, vertical and oblique installation can be performed, so as to meet the needs of use comfort in different shield holding situations. There is no need to prepare multiple shields, which makes it convenient for security personnel to use. Attached Figure Description

[0030] Please see Figure 1-5 A security shield includes a shield body 1, a sliding frame 2 on the inner side of the shield body 1, a sliding shell 3 at one end of the sliding frame 2, the sliding shell 3 slidingly engaging with the sliding frame 2, a buffer spring 4 between the sliding shell 3 and the sliding frame 2, a buffer pad 5 at the other end of the sliding shell 3, and a handheld plate 6 on the buffer pad 5.

[0031] The inner side of the handheld plate 6 is provided with a sliding frame 7. There are two sets of sliding frames 7, which slide in cooperation with the handheld plate 6. One end of the handheld plate 6 is provided with an adjustment knob 8, and the other end is provided with an adjustment screw 9. The threads at both ends of the adjustment screw 9 are arranged opposite to each other. The sliding frame 7 cooperates with the adjustment screw 9. The sliding frame 7 is provided with a hand handle 10.

[0032] In this embodiment, when using the device, the security shield is used through the handheld plate 6. The shield body 1 provides a protective structure for safety protection. When the shield body 1 is subjected to an impact, the impact is transmitted to the arm of the shield holder. The sliding frame 2 and the sliding shell 3 cooperate to provide a retractable structure, so that the buffer spring 4 is stressed. The contraction of the buffer spring 4 absorbs part of the impact force and transmits it to the handheld plate 6 through the buffer pad 5. The buffer pad 5 further absorbs the impact, reduces the pressure of the handheld plate 6 on the shield holder's arm, avoids damage, and makes holding the shield more stable.

[0033] More specifically, when using the equipment, the grip structure on the handheld plate 6 is adjusted according to the user's arm length. By controlling the rotation of the adjustment knob 8, the adjustment knob 8 drives the adjustment screw 9 to rotate. The adjustment screw 9 cooperates with the sliding frame 7 to provide power and control the sliding frames 7 at both ends to move inward, thereby adjusting the position of the sliding frame 7 inside the shield body 1. The sliding frame 7 moves the hand handle 10 so that the position of the hand handle 10 conforms to the arm length and usage habits of the shield holder.

[0034] Please see Figure 1 , Figure 4 and Figure 5 As one implementation method for adjusting the grip: the sliding frame 7 is provided with mounting screw tubes 11, and four mounting screw tubes 11 are provided, symmetrically distributed at the four corners of the sliding frame 7. The handle 10 has mounting holes 12 at both ends, and mounting studs 13 are provided in the mounting holes 12. The mounting studs 13 pass through the mounting holes 12 and cooperate with the mounting screw tubes 11.

[0035] Specifically, the mounting structure is formed by the mounting tube 11 and the mounting stud 13, so that the handle 10 and the sliding frame 7 can be detachably connected. According to the usage requirements, it is determined whether the handle 10 needs to be tilted or vertical. Then, the two ends of the handle 10 are aligned with the appropriate mounting tube 11, and the mounting stud 13 is inserted into the mounting tube 11 through the mounting hole 12, so that the mounting stud 13 and the mounting tube 11 cooperate to fix the handle 10.

[0036] Please see Figure 4 and Figure 5 As a further embodiment of the handheld handle: the two ends of the handheld handle 10 are provided with reinforcing tubes 14, and the mounting screw tube 11 is provided with a reinforcing slot 15, and the reinforcing tube 14 and the reinforcing slot 15 are engaged.

[0037] Specifically, when installing the handheld plate 6, the reinforcing tube 14 is inserted into the reinforcing slot 15 inside the corresponding mounting screw tube 11. During fixing, the mounting stud 13 passes through the reinforcing tube 14. After installation, the reinforcing tube 14 and the reinforcing slot 15 cooperate to make the connection between the handheld plate 6 and the mounting screw tube 11 more stable.

[0038] Please see Figures 1-3 As a further embodiment of the sliding frame: a sliding groove 16 is provided at the outer end of the sliding frame 2, and a sliding block 17 is provided on the inner side of the sliding shell 3. The sliding groove 16 and the sliding block 17 are slidably engaged.

[0039] Specifically, through the cooperation of the sliding block 17 and the sliding groove 16, the sliding groove 16 restricts the sliding of the sliding block 17, thereby keeping the sliding of the sliding frame 2 and the sliding shell 3 stable and preventing the sliding shell 3 from separating from the sliding frame 2.

[0040] Please see Figure 2 and Figure 3 As a further embodiment of the sliding frame: a sliding tube 18 is provided on the inner side of the sliding frame 2, and a sliding column 19 is provided on the inner side of the sliding shell 3. The sliding column 19 is slidably engaged with the sliding tube 18, and both the sliding tube 18 and the sliding column 19 are engaged with the buffer spring 4.

[0041] Specifically, the sliding tube 18 and the sliding column 19 form a guiding structure in the buffer spring 4 through sliding cooperation, so that the buffer spring 4 can work stably.

[0042] Please see Figure 4and Figure 5 As a further embodiment of the handheld plate: a limiting groove 20 is provided on the inner side of the handheld plate 6, and a limiting slider 21 is provided on the inner side of the sliding frame 7. The limiting slider 21 and the limiting groove 20 are in sliding cooperation.

[0043] Specifically, the sliding frame 7 cooperates with the hand plate 6 through the sliding engagement of the limiting slider 21 and the limiting groove 20, and the limiting groove restricts the movement of the limiting slider 21, thereby making the sliding frame 7 and the hand plate 6 stably connected and maintaining the stability of the sliding.

[0044] Please see Figure 1 As a further embodiment of the handheld device: both the handheld device 6 and the sliding frame 7 are provided with fixing straps 22.

[0045] Specifically, the fixing strap 22 provides a fixing structure that can fix the shield to the arm, making it easy to hold the shield with one hand.

[0046] Please see Figure 1 As a further embodiment of the fixing strap: both the hand plate 6 and the sliding frame 7 are provided with fixing ring frames 23, the fixing strap 22 cooperates with the fixing ring frames 23, and the fixing strap 22 is provided with hook and loop fasteners 24 and hook and loop fasteners 25. The hook and loop fasteners 24 and hook and loop fasteners 25 are located on the same side and cooperate with each other.

[0047] Specifically, when using the fixing strap 22, the fixing ring 23 provides a structure so that the movable end of the fixing strap 22 passes through the lower end of the fixing ring 23 and then goes around the fixing ring 23, so that the hook and loop fasteners 24 and 25 fit together and are fixed tightly. The fixing ring 23 fixes the other end of the fixing strap 22, so that the fixing strap 22 tightens around the arm holding the shield.

[0048] In summary, during the use or operation of the overall equipment:

[0049] When using the device, the grip structure on the handheld plate 6 is adjusted according to the user's arm length. The adjustment knob 8 is rotated, causing the adjustment screw 9 to rotate. The adjustment screw 9 engages with the sliding frame 7, providing power to move the sliding frames 7 inwards at both ends. The movement of the limiting slider 21 is restricted by the sliding engagement of the limiting groove 20, ensuring stable sliding between the sliding frame 7 and the handheld plate 6. This adjusts the position of the sliding frame 7 inside the shield body 1. The sliding frame 7 moves the hand handle 10, ensuring its position matches the user's arm length and usage habits. Depending on the needs, the hand handle 10 can be tilted or vertically positioned. An installation structure is formed by the mounting screw tube 11 and mounting stud 13. The two ends of the hand handle 10 are aligned with the appropriate mounting screw tube 11, and the reinforcing tube 14 is inserted into the corresponding reinforcing slot 15 within the mounting screw tube 11. Insert the mounting stud 13 through the mounting hole 12 and the reinforcing tube 14, and into the mounting screw tube 11. This allows the mounting stud 13 to engage with the mounting screw tube 11, securing the handle 10. After installation, the reinforcing tube 14 and the reinforcing slot 15 engage, making the connection between the handpiece 6 and the mounting screw tube 11 more stable. Additionally, when one hand is needed to hold the shield, remove one of the handles 10, leaving only one for gripping. Based on usage habits, it is recommended to adjust the handle 10 to a vertical position. Then, use the fixing strap 22 to provide a fixing structure. Pass the movable end of the fixing strap 22 through the lower end of the fixing ring frame 23, and then around the fixing ring frame 23, allowing the hook and loop fasteners 24 and 25 to engage and securely fasten. The fixing ring frame 23 provides a structure to fix and restrict the other end of the fixing strap 22, making the fixing strap 22 tighten around the arm holding the shield. The hand grips the handle 10, thus enabling one-handed use of the security shield.

[0050] During explosion-proof operations, the shield holder is protected by the shield body 1. When the shield body 1 is subjected to an impact, the impact is transmitted to the shield holder's arm. The sliding frame 2 and the sliding shell 3 cooperate to provide a retractable structure, which allows the buffer spring 4 to be stressed. The buffer spring 4 absorbs part of the impact force through its contraction and is transmitted to the hand-held plate 6 through the buffer pad 5. The buffer pad 5 further absorbs the impact, reducing the pressure of the hand-held plate 6 on the shield holder's arm, avoiding damage, and making the shield holding more stable. The sliding frame 2 and the sliding shell 3 are connected by a sliding block 17 and a sliding groove 16. The sliding groove 16 restricts the sliding of the sliding block 17, keeping the sliding of the sliding frame 2 and the sliding shell 3 stable and preventing the sliding shell 3 from separating from the sliding frame 2. The sliding cooperation of the sliding tube 18 and the sliding column 19 forms a guiding structure in the buffer spring 4, making the buffer spring 4 work stably.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
