Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to a telescopic police shield. Background Technology

[0002] Riot shields, as police defensive equipment, are mainly used to stop violent incidents and ensure the safety of law enforcement officers. Larger police shields have better riot protection performance and can more effectively resist the impact of criminals, but they are large and heavy, making them very inconvenient to carry. Smaller police shields are compact and lightweight, but they can only protect the upper body of the police officer holding the shield, and cannot protect the lower body. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a telescopic police shield that is large in size when extended, provides good protection for police officers, and is small in size when retracted, making it easy to carry.

[0004] The technical solution of this utility model for a telescopic police shield is as follows: It includes a shield body, a fixed seat located in the center of the back of the shield body, fasteners securing both sides of the fixed seat to the shield body, a channel forming between the center of the fixed seat and the shield body, a gripping device located on the side of the fixed seat away from the shield body, a telescopic shield positioned within the channel, and the telescopic shield sliding up and down along the channel via a sliding mechanism. The sliding mechanism includes two sets of upper and lower fixed blocks, each fastened to the shield body, a guide rod positioned between the upper and lower fixed blocks, and sliding sleeves on both sides of the telescopic shield. The sliding sleeves are fitted onto the outer wall of the guide rod, and the telescopic shield slides in cooperation with the guide rod via the sliding sleeves.

[0005] Furthermore, an upper positioning groove and a lower positioning groove are provided on the guide rod, and a ball screw is provided in the sliding sleeve. The head of the ball screw is provided with a positioning ball and a spring, and the positioning ball is positioned and engaged with the upper or lower positioning groove.

[0006] Furthermore, a limiting baffle is provided on the inner side of the lower fixing block, and the limiting baffle cooperates with the two sides of the telescopic shield for limiting.

[0007] Furthermore, the gripping device comprises a handle and an arm sleeve, which are respectively fixed to a mounting base by fasteners.

[0008] Furthermore, buffer pads are provided between the two sides of the fixing base and the shield body.

[0009] Furthermore, a limiting hook is provided on the back of the shield body, and the limiting hook is rotatably connected to the shield body via a pivot. A fixing pin is provided on the telescopic shield, and the limiting hook cooperates with the fixing pin.

[0010] Furthermore, the limiting hook is a double-headed hook.

[0011] The beneficial effects of this utility model of a telescopic police shield are as follows: a telescopic shield is set on the back of the shield body. The telescopic shield slides and extends with the shield body through a sliding mechanism. When the telescopic shield extends downward, the volume of the entire shield increases, which can protect the upper and lower body of the police officer holding the shield, and the protection effect is good. When the telescopic shield is retracted upward, the volume of the entire shield decreases, which makes it easier to carry. Attached Figure Description

[0014] The following description further explains the structures involved in this utility model and the technical terms used therein. These descriptions are merely illustrative of how this utility model is implemented and do not constitute any limitation on this utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0016] In the description of this utility model, unless otherwise explicitly specified and limited, terms such as "connection" and "fixation" should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] This utility model relates to a telescopic police shield, such as Figure 1 — Figure 8 As shown, the shield includes a shield body 1 with an arc-shaped cross-section, its front side being a convex arc and its back side being a concave arc. A fixing seat 2 is provided in the middle of the back side of the shield body 1. The two sides of the fixing seat 2 are fixed to the shield body 1 by fasteners. A channel 3 is formed between the middle of the fixing seat 2 and the concave arc structure on the back side of the shield body 1. A gripping device is provided on the side of the fixing seat 2 away from the shield body 1. A telescopic shield 4 is provided in the channel 3. The cross-section of the telescopic shield 4 is also arc-shaped, and its curvature is... The telescopic shield 4 is aligned with the curvature of the shield body 1 and is positioned close to the shield body 1. The telescopic shield 4 slides up and down along the channel 3 via a sliding mechanism. The sliding mechanism includes two sets of upper fixing blocks 5 and lower fixing blocks 6, which are fixed to the shield body 1 by fasteners. A vertical guide rod 7 is provided between the upper and lower fixing blocks 5 and 6. Sliding sleeves 8 are provided on both sides of the telescopic shield 4. The sliding sleeves 8 are fitted onto the outer wall of the guide rod 7, and the telescopic shield 4 slides with the guide rod 7 via the sliding sleeves 8.

[0018] Furthermore, the guide rod 7 has an upper positioning groove 9 and a lower positioning groove 10. A ball screw 11 is provided in the sliding sleeve 8, with a positioning bead 12 and a spring 17 at the head of the ball screw 11. The positioning bead 12 is positioned and engaged with the upper positioning groove 9 or the lower positioning groove 10. A protruding post can be provided on the sliding sleeve 8, with an internally threaded hole in it. A ball screw 11 is installed in the internally threaded hole, threaded with the hole. The ball screw 11 has a positioning bead 12 and a spring 17 at one end near the guide rod 7. The spring 17 presses against the positioning bead 12, causing one side of the positioning bead 12 to engage in the positioning groove 9 of the guide rod 7, while the other side engages with the head of the ball screw 11 in the sliding sleeve 8. This provides a positioning function between the sliding sleeve 8 and the guide rod 7. When the telescopic shield 4 is pulled with slight force, the positioning bead 12 can be engaged. Positioning bead 12 overcomes the elastic force of spring 17 and retracts into glass bead screw 11, causing sliding sleeve 8 to disengage from guide rod 7. The upper positioning groove 9 allows the telescopic shield 4 to be positioned when it retracts back to the back of shield body 1, preventing it from sliding downwards under gravity. The lower positioning groove 10 allows the telescopic shield 4 to be positioned when it extends to its lowest point, preventing the telescopic shield 4 from retracting when people hold the shield and support the lower end of the telescopic shield 4 on the ground or on their thighs (with the thighs slightly bent forward, the lower end of the telescopic shield can be supported on the thighs).

[0019] Furthermore, a limiting baffle 13 is provided on the inner side of the lower fixing block 6, and the limiting baffle 13 cooperates with the two sides of the telescopic shield 4 for limiting. When the telescopic shield 4 is extended downward, since there is no support at the bottom, the bottom part is prone to deformation when subjected to impact. The limiting baffle 13 can play a certain limiting role in the bottom part of the telescopic shield 4, reducing the deformation of the telescopic shield 4 caused by impact.

[0020] Furthermore, the gripping device comprises a handle 14 and an arm sleeve 15, which are respectively fixed to the mounting base 2 by fasteners. When holding the shield, the arm can pass through the arm sleeve 15 and the hand can grip the handle 14.

[0021] Furthermore, buffer pads 16 are provided between the two sides of the fixed base 2 and the shield body 1. The buffer pads 16 are circular and made of soft rubber material. They can be fitted onto the outer wall of the fastener between the fixed base 2 and the shield body 1. With the buffer pads 16, when the shield body 1 is impacted, the impact force can be buffered to a certain extent, reducing the impact force transmitted to the fixed base 2 and the handle 14.

[0022] Furthermore, a limiting hook 18 is provided on the back of the shield body 1. The limiting hook 18 is rotatably connected to the shield body 1 via a pivot 19. A fixing pin 20 is provided on the telescopic shield 4, and the limiting hook 18 cooperates with the fixing pin 20. After the telescopic shield 4 is retracted, by rotating the limiting hook 18, it hooks onto the fixing pin 20, increasing the tension of the limiting hook 18 and further limiting the telescopic shield 4. This ensures that no matter how the police officers swing the shield when it is retracted, the telescopic shield 4 will not extend downwards.

[0023] Furthermore, the limiting hook 18 is a double-headed hook. The limiting hook 18 can hook the fixing pin 20 by rotating to the left or right, making it easy to operate.

[0024] This utility model discloses a telescopic police shield. In use, the telescopic shield 4 can be pulled down. The telescopic shield 4 slides down along the guide rod 7 via the sliding sleeves 8 on both sides. The guide rod 7 guides the up and down sliding of the telescopic shield 4. When the lower end of the sliding sleeve 8 slides down to contact the lower fixing block 6, the lower fixing block 6 limits the sliding sleeve 8, and the telescopic shield 4 extends downward to its full position. The extended shield body 1 can protect the upper body of the police officer, and the telescopic shield 4 can protect the lower body of the police officer, providing good protection. When not in use or only used as a small shield, the telescopic shield 4 can be pushed upward along the guide rod 7 via the sliding sleeves 8 on both sides. When the upper end of the sliding sleeve 8 contacts the upper fixing block 5, the telescopic shield 4 moves upward to its full position. At this time, the telescopic shield 4 is completely retracted to the back of the shield body 1, reducing the overall size of the shield and making it easier to carry.

[0025] Although the embodiments of this application disclose the above-described methods, the content is merely an implementation method adopted for ease of understanding. Any person skilled in the art should understand that any modifications and changes in the form and details of the implementation can be made without departing from the spirit and scope disclosed in this utility model. However, the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
