The utility model discloses a security barrier gate, which comprises a barrier gate case, a
speed bump and a fence rail, an
assembly structure is arranged between the barrier gate case and the fence rail, and an anti-escape structure is arranged between the
speed bump and the fence rail. According to the barrier gate for security and protection, after the fence
handrail and the barrier gate case are assembled into a whole through the assembling
assembly, then the
speed bump is fixed to the ground of a road entrance and exit, the inserting holes are located under the tire
puncturing nails, when the fence
handrail falls down, the lower ends of the tire
puncturing nails are located in the inserting holes, and when the fence
handrail is lifted up, the tire
puncturing nails are inserted into the inserting holes. Compared with the prior art, when the fence rail is forcibly impacted by a thief during driving, due to the fact that the lower end of the tire puncturing nail is located in the inserting hole and can limit the tire puncturing nail, after the fence rail is impacted to be separated from the barrier gate case, the tire puncturing nail located in the inserting hole punctures a tire of a vehicle, and the safety of the vehicle is improved. Therefore, the vehicle can be prevented from running continuously and escaping, and the vehicle of a thief can be effectively intercepted.
