Safety restraint device for rider

Abstract

The invention discloses a safety restraint device for a rider, which comprises a rider blocking rod installed at the front end of a seat. A guiding mechanism and a guiding rail board which can be guided by the guiding mechanism to only move forwards and backwards are arranged in the middle of the blocking rod. A ratchet bar is arranged on one side of the guiding rail board. A pull rod which can be moved leftwards and rightwards is further arranged on the blocking rod. A movable pawl which can slide left and right relative to the pull rod is arranged at one end of the pull rod. A pawl returning spring which drives the movable pawl to mesh with the ratchet bar is arranged between the movable pawl and the blocking rod. A block which can be connected with the other end of the pull rod in a contacting manner to restrict the pull rod from moving rightwards is arranged on the seat. A pull rod returning spring which can drive the pull rod to pull the movable pawl rightwards away from the ratchet bar after the pull rod separates from the block is arranged between the other end of the pull rod and the blocking rod. The safety restraint device for the rider is simple in structure, low in transmission level and difficult to get stuck.

Description

【Technical field】 [0001] The invention relates to an amusement device, in particular to a passenger safety restraint device. 【Background technique】 [0002] According to the performance, operation mode, speed and structure of the equipment, the amusement facilities must be equipped with corresponding restraint devices. Commonly used restraint devices include seat belts, safety pressure bars, and stop bars. Seat belts can generally be opened by the passenger themselves and are often used as an auxiliary restraint device. The commonly used safety pressure bar can adjust the tightness, and the adjustment mechanism is generally arranged in the seat, and the weight and the required installation space are relatively large. The simple stop lever is relatively light, but because it is not adjustable, there is often a large gap between the restraint device and the passenger after locking, which cannot play a good role in restraint. [0003] The patent number is ZL201020505930.X, a...

The simple stop lever is relatively light, but because it is not adjustable, there is often a large gap between the restraint device and the passenger after locking, which cannot play a good role in restraint

[0003] The patent number is ZL201020505930.X, and the invention patent named a safety seat discloses a safety restraint device. The safety restraint device adopts a rotating structure for one-way adjustment, that is, the linear movement of the pull rod drives the hinge at the end The pawl rotates to control the meshing between the rotating pawl and the gear. The rotation of the gear drives the rack to move in one direction to realize the adjustment distance. The one-way movement of the guide rail needs to pass through multiple rotating pairs, and there are many hinged structures, so the lubrication does not change and it is easy to get stuck
