Description

Triple-protection safety seat with telescopic straps

Technical Field

The invention relates to a manned seat of large-scale amusement equipment, in particular to a triple-protection safety seat with telescopic straps.

Background

At present, large-scale amusement equipment's kind is more, and wherein the class recreational apparatus that rolls is more surprised, amazing and be prepared with visitor's favor, if 360 degrees challengers 'travel (also called big pendulum), wave recreational apparatus etc. that rolls all install safety seat in these amusement equipment, the last thick stick device that is equipped with of safety seat, mainly protects the visitor through pressing the thick stick device to guarantee visitor's safety.

The existing safety seat comprises a seat framework, a pressing rod and a lifting cylinder, wherein a pressing barrel is fixed at the front end of the pressing rod, the pressing rod is hinged to the upper end of a backrest of the seat framework through a pressing rod shaft, the lifting cylinder is hinged to the back of the backrest of the seat framework, a piston rod of the lifting cylinder is hinged to the pressing rod, the piston rod of the lifting cylinder stretches out to drive the pressing rod to rotate to enable the pressing barrel to press tourists, transverse locking hole plates are arranged on two sides of a seat plate of the seat framework, a plurality of locking holes are formed in the transverse locking hole plates, transverse locking cylinders are arranged at two ends in the pressing barrel, the piston rod of each transverse locking cylinder can penetrate into the corresponding locking hole, after the tourists sit on the seat, the pressing rod is slowly put down, two ends of the pressing barrel enter between the two transverse locking hole plates, after the tourists adjust the pressing rod by themselves, an operator cuts off the transverse locking cylinders, the piston rods of the transverse locking cylinders are popped out by internal springs and penetrate into the corresponding locking holes, and locking of the pressing rod is achieved. The pressure bar is fixed with a handrail, the front end of the handrail is provided with a pressure bar safety belt, the pressure bar safety belt can be buckled on a safety belt buckle at the middle part of the front side of the seat board of the seat framework, and the pressure bar safety belt can play a role of fixing the pressure bar when the two transverse locking cylinders fail. The prior safety seat has the following technical defects when in use: 1. although the bar pressing device adopts four-point connection in the design, namely, the two sides of the upper end of the bar pressing device and the two sides of the bar pressing device are mutually redundant, the piston rods of the transverse locking cylinders on the two sides of the bar pressing device are simultaneously broken, and the safety of tourists can be ensured through the bar pressing safety belt, but no further safety guarantee measures are provided for the breakage of the bar pressing device or the breakage of the bar pressing shaft, once the upper half part of the bar pressing device is broken or the bar pressing shaft is broken during the operation of the amusement equipment, the consequences are unreasonable, and the safety of the tourists cannot be ensured. 2. The pressure thick stick device is through pressing a section of thick bamboo to the visitor waist to tie, still persists certain interval between visitor's upper part of the body and the pressure thick stick, and the visitor is mainly for grabbing the handrail with both hands and supporting the upper part of the body when amusement equipment operates to prevent upper part of the body every single move around, because the centrifugal force that the visitor received when amusement equipment operates is great, the front and back horizontal hunting of the unavoidable visitor upper part of the body brings the discomfort for the visitor.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 to 5, a triple-protection safety seat with telescopic straps comprises a seat frame 1, a pressing bar 2 and a lifting cylinder 3, wherein a pressing cylinder 4 is fixed at the front end of the pressing bar 2, the pressing bar 2 is hinged at the upper end of a backrest of the seat frame 1 through a pressing bar shaft 5, a crank 18 is installed at the lower part of the back of the seat frame 1, the lifting cylinder 3 is hinged on the crank 18, a piston rod of the lifting cylinder 3 is hinged with the pressing bar 2, transverse locking hole plates 6 are arranged on two sides of a seat plate of the seat frame 1, a plurality of locking holes 7 are arranged on the transverse locking hole plates 6, transverse locking cylinders 8 are arranged at two ends in the pressing cylinder 4, the piston rod of each transverse locking cylinder 8 can penetrate into the locking hole 7, a swing arm 9 is hinged on the backrest of the seat frame 1, two guide wheels 10 are installed at the upper end of the backrest of the seat frame 1, two straps 11 are connected with the pressing cylinder 4, the two straps 11 are connected with the swing arm 9 after bypassing the guide wheels 10, a support 19 is fixed at the upper part of the back of the seat frame 1, a locking cylinder 12 is hinged with a locking cylinder 12, a hydraulic oil storage cylinder 14, and a closed energy storage rod-free hydraulic oil cylinder 14 and a hydraulic oil storage rod chamber 13 is hinged between the pressure storage cylinder and a hydraulic oil storage rod chamber. Due to the adoption of the technical scheme, after a tourist sits, the pressure bar 2 is slowly put down under the action of the lifting cylinder 3, the two ends of the pressure cylinder 4 enter the space between the two transverse locking hole plates 6, after the tourist automatically adjusts the tightness of the pressure bar 2, an operator cuts off the air of the transverse locking cylinder 8, the piston rod of the transverse locking cylinder 8 is popped out by the internal spring and penetrates into the corresponding locking hole 7, and the pressure bar 2 is locked. Meanwhile, the swing arm 9 is deflected upwards under the traction action of the pressing rod 2 by the two straps 11, the piston rod of the locking oil cylinder 12 is contracted, the two straps 11 can be tied at the shoulders of the tourist for a four-point safety belt structure, the energy accumulator 14 provides smaller initial pressure, and the straps 12 are automatically tightened by utilizing the differential thrust of the downward direction generated by the area difference of the rod cavity and the rodless cavity of the locking oil cylinder 12, so that the straps 12 can automatically cling to the body of the tourist no matter the size of the tourist is tall and thin. After the braces 12 cling to the body of the tourist, the electromagnetic valve 13 can be locked without power off, so that the swing arm 9 can not swing, and the braces 12 can play a role in restraining the tourist. The swing arm 9, the braces 11, the locking oil cylinder 12, the electromagnetic valve 13 and the energy accumulator 14 form a telescopic brace device, if the upper half part of the pressing bar is broken or the pressing bar shaft is broken, the telescopic brace device can still play an effective binding role on passengers, so that the safety of tourists is guaranteed, the safety degree is high, the comfort degree is high, the braces 11 can be opened and closed along with the lifting of the pressing bar 2, the operation is simple, and the automation degree is high. The harness 11 can suppress the sway of the guest during the operation of the device, reducing the discomfort of the guest.

A handrail 15 is fixed on the pressing bar 2, a pressing bar safety belt 16 is arranged at the front end of the handrail 15, a safety belt buckle 17 is arranged in the middle of the front side of a seat plate of the seat framework 1, and the pressing bar safety belt 16 can be buckled on the safety belt buckle 17. The strut safety belt 16 may act to secure the strut 2 in the event of failure of both cross lock cylinders 8.

In conclusion, the invention uses the press bar 2, the braces 11 and the press bar safety belt 16 to carry out triple safety protection, thereby effectively ensuring the safety of tourists.
