Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

A pressing bar restraining device applied to an amusement facility and used for restraining tourists as shown in fig. 1 to 5, which comprises a mounting seat 1 fixed on the amusement facility, wherein a pressing bar 2 capable of swinging back and forth relative to the mounting seat 1 and restraining the tourists on a seat is rotatably connected to the mounting seat 1, a ratchet plate 3 concentric with the rotation axis of the pressing bar 2 is arranged on the ratchet plate 3, a first ratchet 31 is arranged on the ratchet plate 3, a pawl 4 is further arranged on the mounting seat 1, a hinge shaft 5 for rotatably connecting the middle part of the pawl 4 and the mounting seat 1 is arranged between the middle part of the pawl 4 and the mounting seat 1, and a second ratchet 41 capable of being matched with the first ratchet 31 is arranged at the front part of the pawl 4; an elastic piece 6 which can elastically press the pawl 4 to enable the second ratchets 41 to be meshed with the first ratchets 31 and an unlocking device 7 which can act on the pawl 4 to enable the second ratchets 41 to be separated from the first ratchets 31 are arranged between the pawl 4 and the mounting seat 1.

As shown in fig. 5, a seat frame 1a is provided on the amusement ride, a seat 1b is provided on the seat frame 1a, the mount 1 is also provided on the seat frame 1a, and the mount 1 is located below the seat 1 b. The mounting base 1 is provided with a cover 1c for shielding and protecting the structure on the mounting base 1. Preferably, a soft rubber-covered tube 23 (as shown in fig. 1 and 3) is provided at the upper end of the pressing bar 2, and when the pressing bar 2 swings backward and extends into the seat 1b, the soft rubber-covered tube 23 comes into contact with the body of the guest, and restricts the guest from being detached from the seat 1 b. The utility model discloses a press thick stick 2 to be located seat 1 b's below, and in the middle of the two legs of visitor, the visitor takes more comfortablely, and it is convenient to play to sit, presses thick stick 2 more to conveniently open and close, and is safer to visitor's constraint.

As shown in fig. 1, the center of gravity G of the ratchet 4 is located rearward of the hinge shafts 5 so that the second ratchet teeth 41 are engaged with the first ratchet teeth 31 by the self weight of the ratchet 4.

The utility model discloses in, the anterior second ratchet 41 of pawl 4 keeps with the meshing of the first ratchet 31 on the ratchet plate 3 under the effect of elastic component 6 to thick stick 2 is pressed in the locking, presses thick stick 2 and can only one-way pushing down under the effect of ratchet plate 3 and pawl 4, can not open forward, guarantees to press thick stick 2 can not be unexpected to be opened. Since the center of gravity G of the pawl 4 is located rearward of the hinge shaft 5, the center of gravity G of the pawl 4 causes the front portion of the pawl 4 to tend to swing in the direction of the ratchet plate 3 (upward in the drawing). Thus, even if the elastic member 6 fails, the pawl 4 is kept engaged with the ratchet plate 3 by its own weight, thereby locking the pressing bar 2 and preventing the pressing bar 2 from being opened accidentally. The pawl 4 can be under the effect of elastic component 6, can also be under the effect of pawl 4 dead weight locking ratchet plate 3, and elastic component 6 inefficacy does not also influence pawl 4 locking ratchet plate 3, and pawl 4 still can compress tightly ratchet plate 3, has dual safety guarantee, therefore safe and reliable more.
