Folding mechanism of shield

Abstract

The invention discloses a folding mechanism of a shield. The folding mechanism comprises an upper rotating folding mechanism and a lower rotating folding mechanism, wherein the upper rotating folding mechanism comprises an upper rotating switch and an upper base, an arc-shaped upper clamping groove is formed in the upper base, an upper clamping block matched with the upper clamping groove is arranged at the lower part of the upper rotating switch, the upper rotating switch is rotationally connected onto the upper base through matching of the upper clamping block with the upper clamping groove, an upper limiting hole is formed in the upper clamping groove, an upper limiting piece is mounted in the upper limiting hole, an upper arc-shaped groove is formed in the bottom of the upper rotating switch, and the upper limiting piece is clamped in the upper arc-shaped groove; the lower rotating folding mechanism comprises a lower rotating switch and a lower base, an arc-shaped lower clamping groove is formed in the lower base, a lower clamping block matched with the lower clamping groove is arranged at the lower part of the lower rotating switch, and the lower rotating switch is rotationally connected onto the lower base through matching of the lower clamping block with the lower clamping groove. The folding mechanism is simple and flexible to use, and the shield can be folded or unfolded quickly and easily by just rotating the upper rotating switch and the lower rotating switch.

Description

technical field [0001] The invention relates to a shield folding mechanism, belonging to the technical field of police equipment. Background technique [0002] As the main equipment for riot prevention and suppression, shields are widely used in the army and public security system, and they play a role in protecting the safety of law enforcement officers when dealing with emergencies and daily law enforcement. Anti-riot shields are important protective gear for public security and armed police personnel to protect themselves and avoid being attacked by mob missiles when performing tasks. [0003] The one-piece sheet shield structure is not conducive to quick action and carrying in complex situations. However, most folding shields on the market use high-leg hinges or ordinary metal hinges to connect the upper and lower shields, and fix them with bayonet pins. Not only is it time-consuming and laborious to fold, Moreover, in the event of an emergency, it cannot be deployed an...

Problems solved by technology

[0003] The one-piece sheet shield structure is not conducive to quick action and carrying in complex situations. However, most folding shields on the market use high-leg hinges or ordinary metal hinges to connect the upper and lower shields, and fix them with bayonet pins. Not only is it time-consuming and laborious to fold, Moreover, in the event of an emergency, it is impossible to quickly unfold and store it, which affects the safety of the personnel on duty.
