The invention discloses a slow dropping type safety belt, and belongs to the field of safety belts. The slow dropping type safety belt comprises a holding pole belt, wherein the end sockets of the holding pole belt are connected through a buckle; 1 to 3 groups of slow dropping devices are mounted on the outer side of the holding pole belt; the slow dropping devices comprise silk ropes, splay rings and base plates; a U-shaped slot is formed in the lower half section of each base plate; a clamping slot is formed in the inner wall of each U-shaped slot; circular rings at the lower parts of the splay rings are mounted in the clamping slots; clamping buckles for fixing circular rings at the upper parts of the splay rings are arranged at the upper ends of the base plates; and the middle parts of the silk ropes penetrate through the circular rings at the lower parts of the splay rings and are arranged on the circular rings at the upper parts of the splay rings in a sleeving manner. The slow dropping type safety belt overcomes various shortcomings of a pole climbing safety belt in the conventional technology and has a slow dropping function; and furthermore, the safety and the generality are greatly improved.
