[0013] The present invention provides a safety operation device for helicopters, such as... Figure 1-3 As shown, it includes a fan-shaped base plate 1, which can be fixedly installed inside the helicopter cabin. A swingable connecting rod 2 is installed on the fan-shaped base plate 1. One end of the connecting rod 2 is hinged to the axis of the fan-shaped base plate 1, and a seat 3 is installed on the other end of the connecting rod 2.

[0014] The seat 3 has a support frame 4 at its lower part, and an arc-shaped guide rail 5 that cooperates with the support frame 4 is provided on the fan-shaped base plate 1. The seat 3 can move along the length of the arc-shaped guide rail 5, and a five-point safety harness 6 is also provided on the seat 3. The seat 3 provides a relatively stable working space for the operator, and the five-point safety harness 6 effectively avoids the risk of shaking and falling during flight, significantly improving the safety and stability of helicopter operations. Guided by the arc-shaped guide rail 5 and supported and driven by the connecting rod 2, the operator can adjust the position of the seat 3 relative to the arc-shaped guide rail 5 while sitting on the seat 3.

[0015] Footrests 7 are provided on the fan-shaped base plates 1 on both sides of the connecting rod 2. A first footrest plate 8 and a second footrest plate 9 are provided on the outer side of each footrest plate 7. The distance between the first footrest plate 8 and the central axis of the fan-shaped base plate 1 is less than the distance between the second footrest plate 9 and the central axis of the fan-shaped base plate 1. The footrests 7 provide a comfortable foot position for the operator. Furthermore, depending on the position of the seat 3, the operator can adaptively select the footrest to step on. The reaction force from forcefully stepping on the footrest plate achieves the reverse adjustment of the seat 3, thus facilitating the adjustment of body posture during operation.

[0016] To reduce the workload of operators, a mounting base 10 is installed on the fan-shaped base plate 1. The mounting base 10 is located on the upper side of the connecting rod 2. The mounting base 10 can be used to mount working tools such as machine guns or cameras. When the operator is on the seat 3, the working tools on the mounting base 10 can be adjusted as needed to facilitate subsequent normal helicopter operations. During installation, positioning holes can be made at corresponding positions on the fan-shaped base plate 1 according to the actual fixing bolt positions of different helicopter models, so as to fix the entire device to the ground of the aircraft body with bolts or other fasteners, thereby improving the applicability of the device.

[0017] Furthermore, such as Figure 4 As shown, the bottom of the support frame 4 is equipped with a horizontally arranged first guide wheel 11 and a vertically arranged second guide wheel 12. The outer side of the arc-shaped guide rail 5 is provided with a through groove that allows the guide wheel shaft to enter and exit. The first guide wheel 11 is fitted between the two sides of the arc-shaped guide rail 5, and the second guide wheel 12 is fitted between the upper and lower bottom surfaces of the arc-shaped guide rail 5. An inclined brace 21 is also connected between the support frame 4 and the seat 3.

[0018] By cooperating with the first guide wheel 11 and the second guide wheel 12 installed on the support frame 4 and the arc-shaped guide rail 5, the seat 3 can move smoothly on the arc-shaped guide rail 5, reducing frictional resistance and improving movement efficiency. At the same time, the addition of the diagonal brace 21 enhances the stability of the seat 3 structure and ensures safety during operation.

[0019] Furthermore, to facilitate the stable installation of the foot pedal seat 7 on the sector-shaped base plate 1, such as... Figure 5 As shown, the bottom of the foot pedal seat 7 is provided with a folding plate 13, on which a countersunk hole 14 is formed. The fan-shaped base plate 1 is provided with a threaded hole that mates with the countersunk hole 14. A connecting bolt 15 is installed in the threaded hole and the countersunk hole 14. The foot pedal seat 7 is fixedly connected to the fan-shaped base plate 1 through the folding plate 13, the countersunk hole 14 and the connecting bolt 15. This installation method is not only simple and reliable, but also easy to disassemble and maintain, improving the practicality and flexibility of the device.

[0020] Furthermore, in order to increase the swing range of seat 3 and avoid interference from the footrests 7 on both sides of the swing of linkage 2, such as... Figure 6 As shown, a clearance groove 16 is provided on the lower side of the pedal seat 7. The clearance groove 16 is located at the bottom of the first pedal plate 8. A rubber pad 17 is also installed in the clearance groove 16. The connecting rod 2 can swing back and forth between the rubber pads 17 on both sides of the pedal seat 7.

[0021] The avoidance groove 16 and rubber pad 17 on the lower side of the pedal seat 7 effectively prevent direct collision between the connecting rod 2 and the pedal seat 7 when the connecting rod 2 swings, reducing noise and wear. At the same time, the rubber pad 17 also plays a buffering role, further protecting the service life of the connecting rod 2 and the pedal seat 7.

[0022] Furthermore, the placement seat 10 is located on the upper side of the hinge position of the connecting rod 2. In order to facilitate the installation of different types of work tools, a telescopic arm 18 is installed on the placement seat 10. A slewing bearing 19 is installed on the end of the telescopic arm 18 away from the placement seat 10. A top plate 20 is provided on the upper part of the slewing bearing 19.

[0023] The top plate 20 can be provided with screw holes to facilitate the installation of work tools on it as an mounting platform. Rotational adjustment between the top plate and the mounting base 10 is achieved via the slewing bearing 19, and length adjustment between the top plate and the mounting base 10 is achieved via the telescopic arm 18. This allows workers to adjust their own and their tools' posture to achieve the optimal working angle. This structure provides workers with an additional working platform and support points, facilitating the mounting or placement of work tools and equipment, further expanding the functionality and practicality of the device, and providing workers with more operational options and flexibility.

[0024] Furthermore, the foot pedal seat 7 is arranged in an arc shape, and the first foot pedal plate 8 and the second foot pedal plate 9 are both installed on the outer arc surface of the foot pedal seat 7. The first foot pedal plate 8 and the second foot pedal plate 9 are both inclined towards the central axis of the fan-shaped base plate 1, and the interval between the first foot pedal plate 8 and the second foot pedal plate 9 is 40-80cm.

[0025] In summary, the helicopter safety operation device of this utility model has the advantages of reasonable structure, safety and reliability, multiple functions and simple operation. It can effectively improve the safety and efficiency of helicopter operations and has broad application prospects and practical value.
