[0006] This utility model provides a portable telescopic protective shield, which solves the shortcomings of the prior art. Because the protective shield is not easy to extend or shorten according to the application needs, the shield is inconvenient to carry when it is too large and not effective in protection when it is too small, thus reducing the convenience and applicability.

[0007] This utility model provides the following technical solution:

[0008] Portable telescopic protective shield, including:

[0009] A protective shield, wherein the top of the protective shield is symmetrically and fixedly provided with two limit support rods, and the top of the four limit support rods is fixedly provided with the same top plate, and a telescopic shield is provided between the top plate and the protective shield;

[0010] The telescopic mechanism is installed on the protective shield to allow the shield to extend and retract.

[0011] The locking mechanism is installed on the top plate to lock and fix the telescopic shield.

[0012] In one possible design, the telescopic mechanism includes a slide rail, a limiting groove, a fixing frame, and a rotating wheel. Two limiting grooves are provided on the bottom side of the telescopic shield for limiting the sliding of the limiting support rod. Multiple fixing frames are respectively fixedly installed on the inner walls of both sides of the protective shield. Each rotating wheel is rotatably connected between the two sides of the inner wall of the fixing frame via a rotating shaft. Two slide rails are provided on the outer side of the telescopic shield for limiting the rolling of the rotating wheel.

[0013] The top outer walls of both of the limiting support rods are fixedly provided with tension springs, and a fixing rod is fixedly provided on one side of the telescopic shield. The ends of the two tension springs away from the limiting support rods are fixedly provided on the outer wall of the fixing rod.

[0014] In one possible design, the locking mechanism includes a mounting groove, a movable plate, a telescopic pin, a connecting rod, a spring, a top block, and a pull ring. The mounting groove is formed inside the top plate, the movable plate is slidably connected to the inside of the mounting groove, the connecting rod is fixedly disposed on the top side of the movable plate, the spring is sleeved on the outside of the connecting rod, the top and bottom ends of the spring are respectively fixedly disposed on the top side of the inner wall of the mounting groove and the top side of the movable plate, the top end of the connecting rod penetrates the top side of the inner wall of the mounting groove and extends to the top of the top plate, the top block is fixedly disposed on the top end of the connecting rod, and the pull ring is rotatably connected to the top of the top block via a rotating shaft.

[0015] In one possible design, the telescopic pin is fixedly mounted on the bottom side of the movable plate, the bottom end of the telescopic pin penetrates the bottom side of the inner wall of the mounting groove and extends to the bottom of the top plate, and the bottom side of the telescopic shield is provided with a storage locking hole for locking the telescopic pin when it is shortened and stored, and the bottom side of the telescopic shield is provided with a telescopic locking hole for locking the telescopic pin when the protection is extended.

[0016] In one possible design, a storage slot is provided on the top side of the top plate, and a folding handle is rotatably connected inside the storage slot via a pivot. A Velcro strap is fixedly provided on the top side of the top plate for securing the user's arm, and an adjustment buckle is fitted on the outside of the Velcro strap for adjusting and securing it according to the thickness of the user's arm.

[0017] In one possible design, two tungsten carbide window breakers are fixedly mounted on the bottom side of the protective shield.

[0018] In this application, during use, the protective shield, as the main body of the shield, provides basic protective functions, capable of resisting impacts and attacks from the front. The limiting support rods are symmetrically fixed to the top of the protective shield in pairs, providing support and guidance to ensure the telescopic shield maintains a stable trajectory during extension and retraction. The top plate is connected to the protective shield via the limiting support rods, providing top-level limitation and support for the telescopic shield. The telescopic shield is positioned between the protective shield and the top plate, and can be extended or retracted as needed to increase or decrease the protective area. A limiting groove is provided on the bottom side of the telescopic shield, cooperating with the limiting support rods to ensure the telescopic shield moves along a specific trajectory during extension and retraction. Simultaneously, a sliding rail is provided on the outer side of the telescopic shield to provide rolling space for the rotating wheels. A fixed frame is fixed to the inner walls of both sides of the protective shield. The rotating wheels are rotatably connected between the inner walls of the fixed frame via a rotating shaft. When the telescopic shield slides along the limiting support rods, the rotating wheels roll within the sliding rails, reducing friction and facilitating easy and smooth extension and retraction of the telescopic shield, thus improving stability.

[0019] Next, the connecting rod is fixedly mounted on the top side of the moving plate, and a spring is sleeved on the outside of the connecting rod to provide elasticity to the moving plate. The top block is fixedly mounted on the top of the connecting rod, and a pull ring is rotatably connected to the top of the top block via a pivot. When it is necessary to unlock the telescopic shield, the pull ring can be pulled to move the connecting rod and the moving plate downwards, compressing the spring and releasing the telescopic pin. When the pull ring is released, the spring force will cause the moving plate and the telescopic pin to return to their original positions, locking the telescopic shield in the appropriate position. The mounting groove is opened inside the top plate, and the moving plate is slidably connected in the mounting groove. When the telescopic shield needs to be locked, the movable plate slides along the mounting groove to the appropriate position. A telescopic pin is fixed to the bottom side of the movable plate. As the movable plate slides, the telescopic pin moves accordingly. The bottom end of the telescopic pin penetrates the bottom wall of the mounting groove and extends to the bottom of the top plate. It is used to insert into the storage locking hole or telescopic locking hole on the bottom side of the telescopic shield. When the telescopic pin is inserted into the storage locking hole, it can lock and fix the telescopic shield in its retracted state, reducing space occupation, facilitating carrying and storage, and preventing inconvenience caused by the shield shaking during use and carrying. When inserted into the telescopic locking hole, the telescopic shield can be locked and fixed in its extended protective state, further improving the stability of the extended protection. To ensure the telescopic shield automatically returns to its initial position when no external force is applied, tension springs are fixed to the top outer walls of both limit support rods. The other end of the tension springs is fixed to a fixed rod on one side of the telescopic shield. When the telescopic shield is stretched, the tension springs are stretched and store energy. When the external force disappears, the tension springs release the energy, pulling the telescopic shield back to its initial position, achieving an automatic pop-out effect and improving convenience. Two storage slots are provided on the top side of the top plate, each with a folding handle connected via a pivot, facilitating carrying and operation of the shield. To further secure the user's arm, a Velcro strap is also provided on the top side of the top plate. Users can adjust and secure the Velcro strap according to their arm size using the adjustable buckle, improving operational stability. Two tungsten steel window breakers are fixedly installed on the bottom side of the protective shield, allowing for easy window breaking during inspections or missions, enabling escape or attack in emergencies.

[0020] In this utility model, the portable telescopic protective shield can be extended or retracted as needed through a telescopic mechanism to increase or decrease the protective area. This ensures that the telescopic shield moves along a specific trajectory during the extension and retraction process, which helps to make the telescopic shield extend and retract easily and smoothly, thus improving its stability.

[0021] In this utility model, the portable telescopic protective shield can be locked and fixed in the retracted state through a locking mechanism, which reduces the space occupied, makes it convenient to carry and store, avoids the inconvenience caused by the shield shaking during use and carrying, and can also be locked and fixed in the extended protective state, further improving the protective stability after extension.

[0022] In this utility model, the shield can be extended or retracted as needed to increase or decrease the protective area. It can be locked and fixed when the telescopic shield is shortened and stored, reducing the space occupied, making it convenient to carry and store. It avoids the inconvenience caused by the shield shaking during use and carrying, facilitating effective protection and improving convenience and applicability. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] Please refer to Figures 1-6 Protective shields, including:

[0034] The protective shield 1, as the main body of the shield, provides basic protection, capable of withstanding impacts and attacks from the front. Two symmetrically fixed limit support rods 3 are fixed to the top of the protective shield 1, providing support and guidance to ensure the telescopic shield 2 maintains a stable trajectory during extension and retraction. A single top plate 4 is fixed to the top of each of the four limit support rods 3, connecting the top plate 4 to the protective shield 1 via the limit support rods 3, providing top-level limitation and support for the telescopic shield 2. The telescopic shield 2 is positioned between the top plate 4 and the protective shield 1, and can be extended or retracted as needed to increase or decrease the protective area.

[0035] The telescopic mechanism, installed on the protective shield 1, is used for the telescopic shield 2 to extend and retract. The mechanism includes slide rails 5, limiting grooves 6, fixing frames 7, and rotating wheels 8. Two limiting grooves 6 are located on the bottom side of the telescopic shield 2, used to limit the sliding of the limiting support rod 3. The limiting grooves 6 on the bottom side of the telescopic shield 2 cooperate with the limiting support rod 3 to ensure that the telescopic shield 2 moves along a specific trajectory during extension and retraction. Multiple fixing frames 7 are respectively fixed to the inner walls of both sides of the protective shield 1. Each rotating wheel 8 is rotatably connected between the two sides of the inner wall of the fixing frame 7 via a rotating shaft. Two slide rails 5 are located on the outer side of the telescopic shield 2, used to limit the rolling of the rotating wheels 8. When the telescopic shield 2 slides along the limiting support rod 3, the rotating wheels 8 roll within the slide rails 5, reducing friction and facilitating easy and smooth extension and retraction of the telescopic shield 2, thus improving stability.

[0036] Two limit support rods 3 are each fixedly equipped with a tension spring 22 on their top outer wall. A fixed rod 21 is fixedly installed on one side of the telescopic shield 2. The ends of the two tension springs 22 away from the limit support rods 3 are fixedly installed on the outer wall of the fixed rod 21. In order to enable the telescopic shield 2 to automatically return to its initial position when no external force is applied, tension springs 22 are fixed on the top outer wall of the two limit support rods 3. The other end of the tension springs 22 is fixed to the fixed rod 21 on one side of the telescopic shield 2. When the telescopic shield 2 is stretched, the tension springs 22 will be stretched and store energy. When the external force disappears, the tension springs 22 will release energy and pull the telescopic shield 2 back to its initial position, so as to achieve the effect of automatic pop-out and improve convenience.

[0037] A locking mechanism is installed on the top plate 4 to lock and fix the telescopic shield 2. The locking mechanism includes a mounting groove 9, a movable plate 10, a telescopic pin 11, a connecting rod 12, a spring 13, a top block 14, and a pull ring 15. The mounting groove 9 is opened inside the top plate 4. The movable plate 10 is slidably connected to the inside of the mounting groove 9. The connecting rod 12 is fixedly installed on the top side of the movable plate 10. The spring 13 is sleeved on the outside of the connecting rod 12. The top and bottom ends of the spring 13 are respectively fixedly installed on the top side of the inner wall of the mounting groove 9 and the top side of the movable plate 10. The connecting rod 12 is fixedly installed on the top side of the movable plate 10. The spring 13 is sleeved on the outside of the connecting rod 12 to provide elastic force to the movable plate 10. The top end of the connecting rod 12 passes through the top side of the inner wall of the mounting groove 9 and extends to the top of the top plate 4. The top block 14 is fixedly set at the top end of the connecting rod 12. The pull ring 15 is rotatably connected to the top of the top block 14 through a rotating shaft. When it is necessary to unlock the telescopic shield 2, the pull ring 15 can be pulled to move the connecting rod 12 and the moving plate 10 downward, compressing the spring 13 and thus releasing the telescopic pin 11. When the pull ring 15 is released, the elastic force of the spring 13 will cause the moving plate 10 and the telescopic pin 11 to return to their original positions, locking the telescopic shield 2 in the appropriate position.

[0038] Telescopic pin 11 is fixedly installed on the bottom side of movable plate 10. The bottom end of telescopic pin 11 penetrates the bottom side of the inner wall of mounting groove 9 and extends to the bottom of top plate 4. When it is necessary to lock telescopic shield 2, movable plate 10 will slide along mounting groove 9 to the appropriate position. Telescopic pin 11 is fixedly installed on the bottom side of movable plate 10. When movable plate 10 slides, telescopic pin 11 will move accordingly. The bottom end of telescopic pin 11 penetrates the bottom side of the inner wall of mounting groove 9 and extends to the bottom of top plate 4, for insertion into storage locking hole 19 or telescopic locking hole 20 on the bottom side of telescopic shield 2. Storage locking hole 19 is provided on the bottom side of telescopic shield 2 for telescopic pin 11 to lock and fix when it is shortened and stored. When telescopic pin 11 is inserted into storage locking hole 19, it can lock and fix telescopic shield 2 in the shortened and stored state, reducing space occupation, facilitating carrying and storage, and avoiding inconvenience caused by the shield shaking during use and carrying. The bottom side of the telescopic shield 2 is provided with a telescopic locking hole 20, which is used to lock and fix the telescopic pin 11 when the protection is extended. When the telescopic pin 11 is inserted into the telescopic locking hole 20, it can be locked and fixed in the extended protection state of the telescopic shield 2, which further improves the stability of the protection after extension.

[0039] This application can be used in the field of police shields, or in other fields applicable to this application.
