Technical Field

[0001] This utility model relates to the technical field of entertainment cinema supporting equipment, specifically a safety protection device for entertainment cinemas. Background Technology

[0002] With the development of the entertainment industry, 4D and 5D cinemas, which offer immersive and dynamic experiences, have gradually become one of the mainstream forms of entertainment. The seats in these cinemas typically have dynamic functions such as lifting, rocking, and vibration, and special safety protection devices are required to ensure the safety of viewers. Existing cinema seat safety devices mostly employ simple strap or buckle structures, which have the following shortcomings: First, they offer poor protective stability and are prone to loosening during dynamic movement; second, they lack an automatic rebound function, making operation cumbersome, requiring viewers to manually unlock and reset when entering or exiting the seat; and third, they have low structural adaptability, making them difficult to integrate with different models of motion seats, and resulting in significant installation and adjustment challenges. Therefore, those skilled in the art have provided a safety protection device for entertainment cinemas to address the problems mentioned in the background section. Summary of the Invention

[0003] The purpose of this invention is to provide a safety protection device for entertainment cinemas to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A safety protection device for entertainment cinemas includes a fixed base, a connecting rod installed on one side of the fixed base, and a swing arm installed on the other end. One end of the connecting rod is provided with a pressure shoulder, and one end of the swing arm is connected to a ratchet slider. The ratchet slider has buckles installed on both sides of its lower end, and the buckles are installed on a slide block. The slide block is installed on a mounting base, and the lower end of the slide block is provided with a lifting power device, which is equipped with an automatic return device.

[0005] As a further improvement of this utility model: the middle part of the buckle is connected to the slide block through a rotating shaft, and the lower end of the buckle is in contact with the spring clip.

[0006] As a further improvement of this utility model, one end of the spring clip is connected to the slide block via a spring.

[0007] As a further improvement of this utility model: the connecting rod has a U-shaped structure, and both ends of the connecting rod are connected to the crossbar, and both ends of the crossbar are connected to the fixed seat through a rotating shaft.

[0008] As a further improvement of this utility model: the lifting power device adopts a cylinder device, and the air pump automatically fills the cylinder with high-pressure gas when the power is turned on.

[0009] As a further improvement of this utility model: the automatic rebound device is a pressure cylinder filled with high-pressure gas or an oil-gas mixture, and a piston rod is sealed to the upper end of the pressure cylinder.

[0010] As a further improvement of this utility model, the swing arm and the ratchet slider are connected by a movable joint.

[0011] As a further improvement of this utility model: the ratchet slider is provided with a plurality of teeth, the teeth being inclined downward.

[0012] As a further improvement of this utility model: the top of the buckle is engaged inside the teeth. When the ratchet slider moves downward, the force of the buckle and the ratchet slider cancels each other out. When it moves upward, the teeth push open the buckle, and the directions of the forces are the same.

[0013] As a further improvement of this utility model, the mounting base is fixed to the seat of the sports equipment by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperative structure of the ratchet slider and the buckle, when the ratchet slider moves upward with the slide, the buckle engages with the teeth of the ratchet slider under the elastic action of the spring clip. The forces of the two cancel each other out, which can effectively prevent the ratchet slider from falling back, thereby keeping the pressure shoulder in a stable and tight state for the passenger. When unlocking is required, it is only necessary to release the pressure by lifting the power device. The automatic rebound device drives the slide to descend. When the ratchet slider moves downward, the teeth push open the buckle. The forces of the two are in the same direction, achieving smooth unlocking and avoiding accidental loosening or jamming of the protective device.

[0015] 2. The automatic rebound device utilizes a pressure cylinder filled with high-pressure gas or an oil-gas mixture, coupled with a pneumatic lifting power unit. This allows for automatic raising and lowering of the protective device without manual operation, simplifying the user experience and enhancing the overall movie-watching experience. 3. The connecting rod adopts a U-shaped structure and is connected to the fixed seat through a pivot.

[0018] Please see Figures 1-3 In this embodiment of the utility model, a safety protection device for entertainment cinemas includes a fixed base 1, a connecting rod 2, an automatic rebound device 3, a spring clip 4, a sliding base 5, a lifting power device 6, a buckle 7, a pressure shoulder 8, a swing arm 9, a ratchet slider 10, and a mounting base 11. Mounting base 11 is fixed to both sides of the seat of the sports equipment by bolts. The lower end of the slide 5 is connected to the output end of the lifting power device 6. The lifting power device 6 adopts a cylinder device. When the power is turned on, the air pump automatically fills the cylinder with high-pressure gas of 0.6-0.8MPa. The automatic rebound device 3 is located on one side of the lifting power device 6. The automatic rebound device 3 is a pressure cylinder filled with high-pressure gas or oil-gas mixture with a pressure of 0.4-0.6MPa. The lower end of the pressure cylinder is fixedly connected to the mounting base 11, and the upper end of the pressure cylinder is sealed with a piston rod. The top end of the piston rod is fixed to the lower end of the slide block 5. When the lifting power device 6 is de-energized and depressurized, the automatic rebound device 3 can pull the slide block 5 to descend smoothly. The ratchet slider 10 is vertically fixed to the outer wall of the slide block 5. Multiple teeth are evenly arranged on the ratchet slider 10. The teeth are inclined downwards and the tooth spacing is 5-8mm. The protective position can be adjusted according to the user's body size. The buckle 7 is rotatably mounted on the outer wall of the slide block 5 via the central pivot. The buckle 7 is located on one side of the ratchet slider 10. The top of the buckle 7 is matched and engaged with the teeth of the ratchet slider 10. The lower end of the buckle 7 is in contact with one end of the spring clip 4. The other end of the spring clip 4 is connected to the outer wall of the slide block 5 via a spring. The spring is made of stainless steel with a wire diameter of 2mm, an outer diameter of 10mm, and a free length of 20mm. Under the action of the spring force, the spring clip 4 always applies a tightening force to the buckle 7 to ensure that the buckle 7 is stably engaged with the teeth. One end of the swing arm 9 is rotatably connected to the top of the ratchet slider 10 via a movable joint, and the other end of the swing arm 9 is rotatably connected to the middle of the connecting rod 2. The connecting rod 2 has a U-shaped structure, and both ends of the connecting rod 2 are fixedly connected to both ends of the crossbar. Both ends of the crossbar are rotatably connected to the fixed seat 1 via a rotating shaft. The fixed seat 1 is fixed to both sides of the seat back with bolts. The shoulder press 8 is fixed to the end of the connecting rod 2 away from the crossbar. The inner side of the shoulder press 8 is fitted with a buffer layer with a thickness of 10-15mm. The buffer layer is made of high-density sponge or medical silicone material, which can prevent the shoulder press 8 from causing pressure injury to the user's shoulder. An emergency unlock button is also provided on the side of the seat. The emergency unlock button is connected to the buckle 7 via a pull cable. When the button is pressed, the buckle 7 can be pulled to rotate around the pivot, so that the buckle 7 disengages from the teeth of the ratchet slider 10, thereby achieving emergency unlocking. Furthermore, the connecting rod 2 is made of aluminum alloy, and the U-shaped opening faces the inside of the seat. The connection between the connecting rod 2 and the shoulder 8 is fixed by welding to ensure structural strength. Furthermore, the fixing seat 1 is made of die-cast aluminum alloy, and the connecting surface between the fixing seat 1 and the seat back is provided with anti-slip pads to prevent the fixing seat 1 from sliding when the device is working. Furthermore, the swing arm 9 is a telescopic structure, consisting of an inner rod and an outer rod. The inner rod is slidably sleeved inside the outer rod, and the side wall of the outer rod is provided with positioning bolts, which can adjust the overall length of the swing arm 9 and further improve the adaptability of the device.

[0019] Mounting base 11 is fixed to the lower end of the armrests on both sides of the entertainment cinema motion seat with M8 bolts. There are 4 bolts, which are distributed at the four corners of mounting base 11 to ensure that mounting base 11 is firmly connected to the seat without shaking. The slide block 5 is a rectangular metal structure with grooves on both sides that fit the mounting base 11. The slide block 5 slides vertically along the mounting base 11 through the grooves. The lower end of the slide block 5 is fixedly connected to the output end of the lifting power device 6 (cylinder) through a flange. The cylinder model is SC63×100. After being powered on, the air pump can increase the pressure in the cylinder to 0.8MPa within 3 seconds, pushing the slide block 5 to move upward. The automatic rebound device 3 (pressure cylinder) model is Y-HG1. Its bottom is fixedly connected to the cylinder body, and the top piston rod abuts against the center position of the bottom of the slide block 5. The pressure cylinder is pre-charged with 0.5MPa high-pressure nitrogen. When the cylinder is depressurized, the piston rod can push the slide block 5 to descend smoothly at a speed of 50mm / s. The buckle 7 is an L-shaped metal part, the middle of which is rotatably connected to the side wall of the slide block 5 via an 8mm diameter pivot. The top of the buckle 7 is an arc-shaped head that fits the teeth of the ratchet slider 10. The spring clip 4 is made of spring steel. One end of it is fixed to the side wall of the slide block 5 by a bolt, and the other end contacts the lower end of the buckle 7. A 2mm diameter tension spring is also connected between the spring clip 4 and the slide block 5. The initial tension of the tension spring is 5N, which allows the buckle 7 to always have a tendency to swing towards the ratchet slider 10. The ratchet slider 10 has a cuboid structure, with downward-sloping teeth machined on its two side walls facing the buckle 7. The tooth pitch is 15mm and the tooth surface inclination angle is 30°. The swing arm 9 is a metal rod, the lower end of which is connected to the top of the ratchet slider 10 through a movable joint (fisheye bearing). The movable joint can rotate 360°. The upper end of the swing arm 9 is welded to the connecting rod 2. The connecting rod 2 is a U-shaped stainless steel tube with a diameter of 20mm. Both ends of the connecting rod 2 are welded to a crossbar with a diameter of 15mm. The two ends of the crossbar are rotatably connected to the fixed seat 1 through deep groove ball bearings. The fixed seat 1 is fixed to the metal frame on the side of the seat by expansion bolts.

[0020] Shoulder Press 8 is made of curved sponge material and wrapped with PU leather. Its back is connected to the middle of the connecting rod 2 by a metal bracket. The curved radius of Shoulder Press 8 is 150mm, which can fit the shoulder curve of most adults.

[0021] The working principle of this utility model is as follows: After the audience is seated, the cinema control system powers the lifting power device 6 (cylinder), and the air pump fills the cylinder with high-pressure gas. The cylinder pushes the slide 5 to slide upward along the mounting base 11. The slide 5 drives the ratchet slider 10 to rise synchronously. The teeth on both sides of the ratchet slider 10 contact the top of the buckle 7. Under the action of the spring clip 4 and the tension spring, the buckle 7 is engaged in the gap between the teeth, preventing the ratchet slider 10 from falling back. At the same time, the ratchet slider 10 drives the connecting rod 2 to rotate around the axis of the fixed base 1 through the swing arm 9. The connecting rod 2 drives the shoulder press 8 to rotate towards the passenger's shoulder until the shoulder press 8 is in contact with the passenger's shoulder. At this time, the cylinder stops filling with air, and the device remains in a constrained state. After the movie ends, the control system depressurizes the cylinder, reducing the pressure inside to atmospheric pressure. Under the action of high-pressure nitrogen, the piston rod of the automatic rebound device 3 (pressure cylinder) pushes the slide 5 downward, causing the slide 5 to descend along with the ratchet slider 10. The inclined surface of the teeth of the ratchet slider 10 contacts the top of the buckle 7, and the teeth exert an outward pushing force on the buckle 7, overcoming the force of the spring clip 4 and the tension spring, causing the buckle 7 to swing outward around the axis and disengage from the tooth gap. As the slide 5 continues to descend, the swing arm 9 drives the connecting rod 2 to rotate in the opposite direction, and the shoulder press 8 moves away from the passenger's shoulder until the slide 5 reaches its lowest position, completing the rebound process.

[0022] In this embodiment, the protective restraint force of the device can be adjusted by adjusting the cylinder inflation pressure (0.6-0.9MPa) to accommodate passengers of different weights. Simultaneously, the shoulder pressure pad 8 has a sponge thickness of 30mm, providing cushioning and preventing pressure injuries to passengers. The entire device has a compact structure, with all components working smoothly together, effectively meeting the safety protection requirements of entertainment cinema seats.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
