Description

Press bar binding device applied to recreation facility

Technical Field

The invention relates to the technical field of amusement facilities, in particular to a pressing bar binding device applied to amusement facilities.

Background

Most of seats of amusement facilities are provided with a pressing bar binding device for protecting tourists and preventing the tourists from separating from the seats. The prior pressing bar binding device (such as the patent with publication number CN 103100158A applied by the applicant) generally comprises a pressing bar capable of swinging inwards and outwards, and the pressing bar swings inwards towards the seat to limit tourists on the seat, so that the pressing bar realizes unidirectional rotation of the pressing bar and locks the maximum opening position through a ratchet pawl structure. However, the pawl in the pressing bar binding device is usually meshed with the ratchet wheel only through the jacking of the spring, if the spring is too loose or even fails, the pawl can not be tightly meshed with the ratchet wheel, and the pressing bar has the safety risk of being opened accidentally.

In addition, in some existing press bar binding devices, a driver such as an air cylinder is used for directly driving a pawl to swing, if the driver is blocked and cannot fall back, the pawl can be interfered by the driver and cannot be separated from a ratchet wheel, so that the pawl is difficult to stir manually, and great difficulty is caused to manual emergency rescue.

Furthermore, in some existing pressing bar binding devices, the pressing bars are usually installed at the front of the toes or the front of the lower legs of the tourists, or are connected in rows, so that the problems of large volume, inconvenient opening and closing of the pressing bars, uncomfortable riding of the tourists and the like are caused.

When the output end of the unlocking driver extends forwards, the pawl is meshed with the ratchet plate again under the action of the dead weight and the elastic piece. If the unlocking driver fails, the front part of the pawl can be manually and backwards shifted, and the front part of the pawl swings backwards to be separated from the ratchet plate. In this structure, dial the front portion of pawl backward, what kind of state of unblock driver can not interfere the motion of pawl, even the unblock driver is blocked like this, thereby also can dial the front portion of pawl backward thereby unblock press bar, consequently more reliable, more be favorable to emergency rescue.

3. Because the mounting groove with the same shape as the ratchet wheel plate is processed on the pressing bar and used for fixing the ratchet wheel plate, the load of the ratchet wheel plate can be transmitted through the mounting groove, so that the screw is prevented from being directly stressed, and the ratchet wheel plate is safer and more durable.

Detailed Description

In order to make the technical scheme 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.

The device is used for binding tourists and comprises a mounting seat 1 fixed on the amusement facility, wherein the mounting seat 1 is rotatably connected with a pressing bar 2 which can swing back and forth relative to the mounting seat and can bind the tourists on a seat, the pressing bar 2 is provided with a ratchet plate 3 concentric with the rotation axis of the pressing bar, the ratchet plate 3 is provided with a first ratchet 31, the mounting seat 1 is also provided with a pawl 4, a hinge shaft 5 which is rotatably connected with 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 the front part of the pawl 4 is provided with a second ratchet 41 which can be matched with the first ratchet 31; an elastic member 6 capable of elastically pressing the pawl 4 to engage the second ratchet 41 with the first ratchet 31, and an unlocking device 7 capable of acting on the pawl 4 to disengage the second ratchet 41 from the first ratchet 31 are provided between the pawl 4 and the mount 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 seat 1 is provided with a cover 1c for shielding and protecting the structure on the mounting seat 1. Preferably, a soft rubber coating pipe 23 (as shown in fig. 1 and 3) is arranged at the upper end of the press bar 2, and after the press bar 2 swings backwards into the seat 1b, the soft rubber coating pipe 23 contacts with the body of the tourist, so that the tourist is restrained from being separated from the seat 1 b. The pressing bar 2 is positioned below the seat 1b, and in the middle of two legs of a tourist, the tourist sits more comfortably, the sitting is convenient, the pressing bar 2 is more convenient to open and close, and the binding of the tourist is safer.

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

In the invention, the second ratchet 41 at the front part of the pawl 4 is kept engaged with the first ratchet 31 on the ratchet plate 3 under the action of the elastic piece 6, so that the pressing bar 2 is locked, the pressing bar 2 can only be pressed downwards under the action of the ratchet plate 3 and the pawl 4 and cannot be opened forwards, and the pressing bar 2 cannot be opened accidentally. And 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 tends to cause the front portion of the pawl 4 to swing in the direction of the ratchet plate 3 (upward direction in the drawing). In this way, 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 avoiding the pressing bar 2 from being opened accidentally. The pawl 4 can lock the ratchet plate 3 under the action of the elastic piece 6 and the self-weight action of the pawl 4, the failure of the elastic piece 6 does not affect the locking of the pawl 4 to the ratchet plate 3, and the pawl 4 can still press the ratchet plate 3, so that the safety and reliability are improved.

When the output end of the unlocking driver 72 is retracted backward, the rear part (upper part) of the shift lever 71 is driven to swing backward, and thus the front part (lower part) of the shift lever 71 swings forward, so that the rear part of the pawl 4 is pushed upward, and thus the front part of the pawl 4 swings backward, so that the ratchet plate 3 is disengaged, the pressing bar 2 is unlocked, and the pressing bar 2 can be opened forward. When the output end of the unlocking actuator 72 is extended forward, the pawl 4 is reengaged with the ratchet plate 3 under its own weight and the elastic member 6.

Notably, if the unlocking actuator 72 fails, the front portion of the pawl 4 can be manually toggled back manually, the front portion of the pawl 4 swinging back out of engagement with the ratchet plate 3. In this structure, the front part of the pawl 4 is pushed backward, and the unlocking driver 72 does not interfere with the movement of the pawl 4, so that the unlocking driver 72 can push the front part of the pawl 4 backward even if it is stuck, thereby unlocking the press bar 2, and thus, the operation is more reliable and more advantageous for emergency rescue.

In a more specific embodiment of the invention, the unlocking actuator 72 is a linear actuator hinged to the mounting base 1. The unlocking actuator 72 is preferably an electric push rod, but may be a cylinder, a rack and pinion, or the like.
