A device for preventing over-tightening of winding spring

Abstract

The invention discloses a device for preventing a wind from being tight. The device for preventing the wind from being tight comprises a fixed machine body, a rotary space is arranged in the fixed machine body, a gear disc is arranged in the rotary space, an output shaft is fixedly connected to the center position of the left end surface of the gear disc, and the left end of the output shaft penetrates through the left end wall of the rotary space and extends into an external space and is connected with wind power. Locking mechanisms are arranged on the two sides of the gear disc up and down, and worm gear mechanisms are arranged on the left sides of the locking mechanisms. According to the device for preventing the wind from being tight, a meshing structure and hydraulic transmission are adopted, and the stability of equipment in the motion process is ensured; and meanwhile, the linkage and harmony between equipment links are enhanced, limitation of rotation times of is realized, the situation that the wind is tight and even damaged due to excessive rotation times of is avoided, and the selectivity of the equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of spring protection equipment, in particular to a device for preventing over-tightening of the winding spring. Background technique [0002] Some children's toys are driven by springs, and children are just starting to get in touch with them, and they basically can't control the number of rotations. This can easily cause the springs to be too tight, causing damage to the springs or directly driving the toy to rotate. Injure children themselves, and there are relatively few devices on the market to prevent over-tightening of the mainspring, which are generally related to mechanical clocks and watches, which are mainly relieved by the slipping of the mainspring itself. Although the over-tightening of the mainspring is avoided, it cannot Effectively defining the number of rotations, to a certain extent, will still cause damage to the mainspring.
