Detailed Description

Referring to fig. 1 to 3, the present embodiment provides an automatic opening blocking mechanism, which includes a mounting seat 1, a blocking member 2, a rotating shaft 3, a limiting member 4, and an elastic force returning member 5.

An inclined surface forming passing part 21 is arranged on one side of the upper part of the blocking component 2, the inclined angle a of the inclined surface is 40-50 degrees, a blocking part 22 is formed on the corner part of the other side, a limiting part 23 is convexly formed on the other side of the middle part of the blocking component 2, and a concave position 24 is arranged on one side of the middle part of the blocking component 2. On the basis of guaranteeing structural strength, reduce materials, reduce cost and weight reduction promote the action flexibility.

The lower part of the blocking member 2 protrudes outwards to form a trigger part 25, and in particular, the lower side edge of the blocking member 2 is turned outwards to form the trigger part 25. Thus, the passing part 21, the blocking part 22, the limiting part 23 and the triggering part 25 form an integrated connection structure, and the integrated structure has high strength and good stability.
