Description

Technical Field

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

[0002] Existing security shields are equipment used to defend and protect security personnel, other law enforcement officers, and the public, especially helping security personnel withstand attacks and injuries while performing their duties. Current shields have a relatively simple structure, typically consisting of a rectangular shield shell and handles. The shield shell is usually made of high-strength materials such as aluminum alloy and steel alloy, offering advantages such as light weight, high strength, and good protective performance. However, in some actual usage scenarios, criminals, realizing they cannot directly approach security personnel through the shield, may resort to grasping the side of the shield and forcefully prying it open to partially expose the security personnel outside the shield's protective area, or even loosening the shield altogether. Furthermore, because the shield's size is insufficient to cover the entire height of a standing adult, in some scenarios, security personnel may kneel on one knee and hold the shield upright in front of them for full protection; however, with the bottom of the shield resting on the ground, it is prone to tipping over. Therefore, existing security shields still need further improvement in their protective effectiveness across more usage scenarios. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a protective shield to solve one or more of the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides a protective shield, including a shield shell:

[0005] A handle is located on the back of the shield.

[0006] A strip plate is provided parallel to the back side of the shield. Multiple spikes are spaced apart along the length of the outer side of the strip plate. The inner side of the strip plate is elastically connected to the shield and is used to elastically pull the strip plate inward so that the spikes are retracted into the side of the shield.

[0007] A turntable is rotatably connected to the back of the shield, located inside the strip plate. When the spikes are in the retracted state, the outer side of the turntable abuts against the inner side of the strip plate. The outer circumference of the turntable is provided with an incomplete outer ring. By rotating the turntable, the incomplete outer ring pushes the strip plate outward, so that the spikes are in a protruding state beyond the side of the shield.

[0008] An adjustment knob is rotatably connected in the middle of the shield shell. A connecting rope is wound around the adjustment knob, and one end of the connecting rope is wound around the turntable. By rotating the adjustment knob, the connecting rope is wound around the adjustment knob, which drives the turntable to rotate so that the spikes are in an extended state.

[0009] Preferably, an observation window is provided at the upper end of the shield.

[0010] Preferably, a protective pad is provided in the middle of the shield, and the handle is vertically located on one side inside the protective pad.

[0011] Preferably, a shield band is provided inside the pad on the opposite side of the handle.

[0012] Preferably, the pad has an opening through which the adjustment knob passes.

[0013] Preferably, the inner side of the strip plate is provided with an arc-shaped groove, and the outer side of the turntable abuts against the arc-shaped groove.

[0014] The beneficial effects of this utility model are as follows: A strip plate is parallel to the back side of the shield shell, and multiple spikes are spaced apart along the length of the outer side of the strip plate. The inner side of the strip plate is elastically connected to the shield shell, so that the spikes are retracted into the side of the shield shell. A turntable is rotatably connected to the back of the shield shell, located inside the strip plate. The turntable has an incomplete outer ring around its outer circumference. An adjustment knob is rotatably connected to the middle of the shield shell, and a connecting rope is wound around the adjustment knob. One end of the connecting rope is wound around the turntable. If necessary, rotating the adjustment knob will cause the connecting rope to wind around the adjustment knob, causing the turntable to rotate synchronously. The incomplete outer ring pushes the strip plate outward, so that the spikes extend beyond the side of the shield shell, providing a stronger protective effect. Additionally, if necessary, manually rotating the turntable at the bottom will only extend the spikes at the bottom, allowing them to penetrate the ground, providing a stable support and preventing tipping, thus more effectively resisting impacts.

[0026] A protective shield includes a shield shell 1. A handle 2 is located on the back of the shield shell 1. A strip plate 3 is parallel to the side of the back of the shield shell 1. Multiple spikes 4 are spaced apart along the length of the outer side of the strip plate 3. The inner side of the strip plate 3 is elastically connected to the shield shell 1, allowing it to be elastically pulled inwards to retract the spikes 4 into an inward-facing state within the side of the shield shell 1. A turntable 5 is rotatably connected to the back of the shield shell 1, located inside the strip plate 3. When the spikes 4 are in the inward-facing state, the outer side of the turntable 5 abuts against... On the inner side of the strip plate 3, the outer circumference of the turntable 5 is provided with an incomplete outer ring 6. By rotating the turntable 5, the incomplete outer ring 6 pushes the strip plate 3 outward, so that the spike part 4 is in a protruding state beyond the side of the shield shell 1. An adjustment knob 7 is rotatably connected at the middle position of the shield shell 1. A connecting rope 8 is wound around the adjustment knob 7. One end of the connecting rope 8 is wound around the turntable 5. By rotating the adjustment knob 7, the connecting rope 8 is wound around the adjustment knob 7, which drives the turntable 5 to rotate, so that the spike part 4 is in a protruding state.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, this utility model features a shield shell 1 with a handle 2 on its back. The handle 2 is typically vertically oriented for easy gripping by security personnel to lift the shield shell 1 and protect it in front of them. Specifically, a strip plate 3 is parallel to the side of the back of the shield shell 1. Preferably, the strip plates 3 are symmetrically distributed on the four sides of the back of the shield shell 1, with their length parallel to the side. Multiple spikes 4 are spaced along the length of the outer side of the strip plates 3. The spikes 4 can have a serrated design along the length of the outer side of the strip plates 3. The shield shell 1, handle 2, strip plates 3, and spikes 4 can be made of conventional shield materials such as aluminum alloy and steel alloy, offering advantages such as light weight, high strength, and good protective performance. The inner side of the strip plate 3 is elastically connected to the shield shell 1. Specifically, as shown... Figure 2 As shown, an elastic connection can be achieved using conventional elastic components such as springs, which are used to elastically pull the strip plate 3 inward so that the spike 4 is retracted into the side of the shield shell 1, as shown. Figure 2 , Figure 3 , Figure 4As shown, without affecting the normal use, storage, and wearing of the shield, a turntable 5 is rotatably connected to the back of the shield shell 1, located inside the strip plate 3. When the spikes 4 are in the retracted state, the outer side of the turntable 5 abuts against the inner side of the strip plate 3. An incomplete outer ring 6 is provided around the outer periphery of the turntable 5. An adjustment knob 7 is rotatably connected to the middle position of the shield shell 1. A connecting rope 8 is wound around the adjustment knob 7, and one end of the connecting rope 8 is wound around the turntable 5. Both the turntable 5 and the adjustment knob 7 can be designed in a circular shape, and grooves can be opened on their outer periphery for the connecting rope 8 to be wound. In some special use scenarios, if necessary, the adjustment knob 7 can be rotated, for example... Figure 5 , Figure 6 As shown, rotating the adjustment knob 7 counterclockwise by approximately 120° causes the connecting ropes 8 to wind around the adjustment knob 7, thereby causing the turntables 5 to rotate synchronously. At this time, the incomplete outer ring 6 pushes the strip plate 3 outward, so that the spikes 4 extend beyond the side of the shield shell 1. In this state, it is difficult for criminals to grasp and pry open the side of the shield. The protruding spikes 4 also provide a stronger deterrent effect and can destroy weapons in the hands of criminals, thus providing a stronger protective effect. In addition, in certain special usage scenarios, if necessary, security personnel can adopt a kneeling position on one leg. At this time, the turntable 5 at the bottom can be manually rotated until the incomplete outer ring 6 pushes the strip plate 3 outward, so that the spikes 4 at the bottom end extend outward, allowing the spikes 4 at the bottom end to penetrate into the ground, thus providing a stable stand and preventing it from tipping over, and more effectively resisting impact.

[0028] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 As shown, the upper end of the shield shell 1 is provided with an observation window 9. The observation window 9 can be designed with a transparent structure or a mesh structure to ensure that there is still an open view when full protection is provided.

[0029] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 As shown, a pad 10 is provided in the middle of the shield 1, and the handle 2 is vertically located inside the pad 10. When the hand holds the handle 2, the arm rests against the pad 10, which helps to further improve comfort and cushioning protection.

[0030] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 As shown, a shield strap 11 is provided inside the pad 10 on the opposite side of the handle 2. When the hand holds the handle 2 and the arm rests against the pad 10, the shield strap 11 on the other side is wrapped around the arm and tightened, which facilitates further secure wearing and use.

[0031] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2As shown, the pad 10 has an opening 12 for the adjustment knob 7 to pass through, which facilitates the convenient use of the adjustment knob 7.

[0032] Even better, the connecting rope 8 is threaded through the gap between the pad 10 and the shield 1. A hollow conduit can also be fixed in the gap between the pad 10 and the shield 1, and the connecting rope 8 is threaded through the conduit, which facilitates the efficient transmission and connection of the connecting rope 8.

[0033] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the inner side of the strip plate 3 is provided with an arc-shaped groove 30, and the outer side of the turntable 5 abuts against the arc-shaped groove 30, which facilitates the turntable 5 and the incomplete outer ring 6 to rotate and push the strip plate 3 more efficiently.
