[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, an elliptical block is fixed on a rotating shaft. When the movable pressure rod rotates due to wear of the connecting parts, the rotating shaft rotates, and the elliptical block rotates with the rotating shaft, tilting to reduce the distance between the two baffles. Under the action of the supporting spring force, the two baffles move closer to each other, causing the two slide plates to slide along the slide rod and move closer to each other, simultaneously pushing both ends of the spring plate, causing the spring plate to deform. This causes the highest point of the spring plate to rise and press against the switch button. Pressing the switch button illuminates the indicator light. After the entertainment ends, the staff can know that the movable pressure rod has rotated by observing the indicator light, and can immediately carry out maintenance to reduce safety hazards.

[0018] 2. In this utility model, the insert plate is rotated by rotating the support plate, and the telescopic plate moves along the inside of the support plate, so that the insert plate installed at one end of the telescopic plate is inserted into the corresponding position inside the connecting shell. The insert plate can be fixed in the connecting shell by screw one and through hole matching screw groove one. The position between the support plate and the telescopic plate is fixed by screw two and screw groove two. At this time, the support plate and the telescopic plate can support and reinforce the position between the seat and the movable pressure rod, making the movable pressure rod more stable and effectively improving the stability of the safety pressure rod.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A safety lever mechanism, such as Figures 1-6 As shown, the device includes a seat 1 and a movable pressure rod 2. Support plates 3 are fixedly installed on the upper part of the two outer side walls of the seat 1. A rotating shaft 4 is rotatably connected between the outer side walls of the two support plates 3, and both ends of the movable pressure rod 2 are fixedly connected to the rotating shaft 4. Two connecting plates 5 are fixedly connected to the back of the seat 1, and both connecting plates 5 are sleeved on the outside of the rotating shaft 4. Two reinforcement mechanisms are provided between the movable pressure rod 2 and the outer side wall of the seat 1. One of the connecting plates 5 has a warning mechanism on its outer side wall. The warning mechanism includes an elliptical block 19, two indicator lights 26, and two slides. The elliptical block 19 is sleeved on the outside of the rotating shaft 4. The two indicator lights 26 are fixedly installed on the outer side wall of the connecting plate 5. The two slides are opened on the outer side wall of the connecting plate 5. A slide rod 10 is fixedly installed inside the two slides. A slide plate 9 is sleeved on the outside of the two slide rods 10 near both ends. A baffle 11 is fixedly connected to the outer side wall of the two slide plates 9.

[0030] The two ends of the elliptical block 19 are tightly attached to the outer walls of the two baffles 11. Together with the support spring and the sliding plate 9, the distance between the two baffles 11 can be limited. When the elliptical block 19 rotates and tilts to a certain angle, and this rotation angle is not enough to release the pressure and fixation of the personnel by the movable pressure rod 2, it can release the two baffles 11 by a certain pushing distance. Together with the elastic force of the support spring, the distance between the two baffles 11 is reduced.

[0031] Two limiting blocks 12 are fixedly connected to the outer walls of the two baffles 11, and the inner walls of the four limiting blocks 12 are tightly attached to the elliptical block 19. The four limiting blocks 12 can limit the position of the elliptical block 19 and prevent it from contacting the rotating shaft 4.

[0032] The outer wall of the rotating shaft 4 has an annular groove 13 and a fixing hole 14. The inner wall of the two sliding grooves has a groove 17. A switch button 16 is installed on the inner wall of the groove 17. The output end of the switch button 16 is electrically connected to the input end of the indicator light 26. Pressing the switch button 16 will turn on the indicator light 26.

[0033] Two slide bars 10 are fitted with spring pieces 15 on their outer sides and between the two slide plates 9. Support springs are fitted on the outer sides of the two slide bars 10 near both ends. The highest point of the spring piece 15 is in contact with the switch button 16.

[0034] A fixed frame 18 is fixedly connected to the outer wall of the elliptical block 19. A telescopic push rod 20 is fixedly connected to the top of the inner part of the fixed frame 18. A return spring is sleeved on the outside of the telescopic push rod 20. A fixed insertion rod 21 is fixedly connected to the bottom of the telescopic push rod 20. The fixed insertion rod 21 passes through the outer wall of the elliptical block 19 and fits into the fixed hole 14.

[0035] A mounting base 8 is fixedly connected to the outer wall of the support plate 3. The inner wall of the mounting base 8 and the outer wall of the support plate 3 are rotatably connected to gears 6 through shafts. One of the gears 6 is fixedly connected to the rotating shaft 4. A motor is installed on the outer wall of the mounting base 8, and the output end of the motor is connected to the other gear 6. The two gears 6 are meshed with each other.

[0036] In use, seat 1 can be installed on amusement facilities for tourists to ride. After a tourist sits on seat 1, the motor on mounting base 8 drives one of the gears 6 to rotate, which in turn drives another gear 6 to rotate, which in turn drives the rotating shaft 4 to rotate, causing the movable pressure rod 2 to rotate and press down on the tourist's position for protection. During the rotation of the rotating shaft 4, the elliptical block 19 is inserted between the four limiting blocks 12 and is located outside the annular groove 13, not in contact with the rotating shaft 4, and remains relatively fixed, thus not hindering the rotation of the rotating shaft 4. After the movable pressure rod 2 has rotated and fixed the tourist's position, the elliptical block 19 can be moved from the position between the four limiting blocks 12. Pull out and slide it onto the outer wall of the rotating shaft 4. When the elliptical block 19 is moved and fitted onto the outer wall of the rotating shaft 4, the fixing rod 21 is moved upward so that the bottom end of the fixing rod 21 is above the rotating shaft 4. At this time, the telescopic push rod 20 is shortened and the return spring is squeezed and contracted until the elliptical block 19 is moved and fitted onto the outer wall of the rotating shaft 4. Then, the fixing rod 21 is released. Under the action of the return spring, the telescopic push rod 20 is extended, which can drive the fixing rod 21 to move downward so that the fixing rod 21 passes through the elliptical block 19 and inserts into the fixing hole 14, fixing the elliptical block 19 onto the rotating shaft 4. At this time, the amusement facility can be started to move the seat 1 for entertainment.

[0037] During the movement of seat 1, if the movable pressure rod 2 rotates due to wear of the connecting parts, i.e., the rotating shaft 4 rotates, the elliptical block 19 can rotate with the rotating shaft 4, causing the slide plate 9 to tilt, reducing the distance between the two baffles 11. Under the action of the supporting spring force, the two baffles 11 can be driven to move closer to each other, causing the two slide plates 9 to slide along the slide rod 10 and move closer to each other, pushing both ends of the spring piece 15 at the same time, causing the spring piece 15 to deform, so that the highest point of the spring piece 15 rises, pressing against the switch button 16. Pressing the switch button 16 will cause the indicator light 26 to light up. After the entertainment is over, the staff can know that the movable pressure rod 2 has rotated by the lighting of the indicator light 26, and can immediately carry out inspection and maintenance to reduce safety hazards.

[0038] The reinforcement mechanism includes a connecting shell 24 and a support plate 22. The connecting shell 24 is fixedly connected to the bottom surface of the movable pressure rod 2. The support plate 22 is rotatably connected to the outer wall of the seat 1 via a shaft. A telescopic plate 25 is inserted inside the support plate 22. An insert plate 23 is rotatably connected to the end of the telescopic plate 25 away from the support plate 22 via a shaft. Several through holes are opened through the outer wall of the connecting shell 24. A screw is inserted into one of the through holes. A screw groove is opened on the outer wall of the insert plate 23, and the screw groove fits with the screw. A screw is inserted on the outer wall of the support plate 22. Several screw grooves are opened on the outer wall of the telescopic plate 25, and the screw grooves fit with the screws.

[0039] Specifically, after the movable pressure rod 2 rotates and presses to fix the tourist position, the support plate 22 can be rotated to drive the insert plate 23 to rotate, and the telescopic plate 25 can be moved along the inside of the support plate 22, so that the insert plate 23 installed at one end of the telescopic plate 25 is inserted into the corresponding position inside the connecting shell 24. At this time, screw one is passed through the corresponding through hole and rotated into the screw groove one, so that the insert plate 23 can be fixed in the connecting shell 24 and one end of the telescopic plate 25 is fixed. Then, screw two is passed through the support plate 22 and rotated into the corresponding screw groove two, so that the position between the support plate 22 and the telescopic plate 25 is fixed. At this time, the support plate 22 and the telescopic plate 25 can support and reinforce the position between the seat 1 and the movable pressure rod 2, making the movable pressure rod 2 more stable and effectively improving the stability of the safety pressure rod.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
