[0036] like Figure 2 As shown, the present application provides a throttle lever synchronization device, which consists of a throttle lever head, a lateral extension rod, a linkage device, and a locking device.

[0037] Among them, the throttle rod head is divided into an intermediate throttle rod head and a side throttle rod head. The intermediate throttle rod head is installed on the head ball of the second engine throttle rod and the third engine throttle rod, and the side throttle rod head is installed on the head ball of the first engine throttle rod and the fourth engine throttle rod, and is used to drive the throttle rod to move; the locking device is connected to the throttle rod head through a thread, and is used to lock the throttle rod head on the throttle rod head ball; the linkage device is connected to the third mounting hole 8 of the side throttle rod head through a thread, and the position of the bolt shaft in the side throttle rod head is changed to realize the rapid switching between four-engine linkage and two-engine linkage; the lateral extension rod is connected to the intermediate throttle rod head through a thread, which can shorten the distance between the driver and the throttle rod and reduce the driver's operating burden.

[0038] In other embodiments of the present application, the present application provides an aircraft throttle lever synchronization device, in which the throttle lever head is divided into two parts: a middle lever head and a side lever head. The linkage of the second and third engines or the first, second, third and fourth throttle levers can be quickly realized or released in the air or on the ground, so that the throttles of each engine are synchronized as much as possible, reducing the state differences of each engine caused by human factors, and improving the throttle control accuracy during the aerial refueling process.

[0039] Among them, the locking device adopts an eccentric wheel mechanism with a simple structure and easy operation, and can quickly complete the disassembly of the throttle lever synchronization device in the air or on the ground; the throttle lever head and the lateral extension rod are made of polytetrafluoroethylene material. Compared with traditional metals, it has the advantages of light weight, stable chemical properties, strong environmental adaptability, and super wear resistance, which increases the service life of the device; the linkage device and the locking device are made of aluminum alloy, which is light weight and has good rigidity. When locking, it can effectively press the throttle lever head of the synchronization device firmly onto the small ball on the throttle lever head, thereby improving the accuracy of the device; the various components of the synchronization device are easy to process, low cost, easy to disassemble and assemble, with good interchangeability and easy management.

[0040] In one possible implementation, the throttle lever head 1 is divided into two parts: a middle throttle lever head 5 and a side throttle lever head 6. The throttle lever head is provided with a second mounting hole 7, a third mounting hole 8, and a first mounting hole 10. The mounting holes are provided with threads for mounting the locking device 4, the linkage device 3, and the lateral extension rod 2.

[0041] The shape of the throttle rod ball slot 9 is similar to the shape of the throttle rod ball. Since the material is polytetrafluoroethylene, when the eccentric wheel of the locking device applies pressure, the slot will deform slightly, making the slot and the throttle rod ball fit together tightly. Figure 3 .

[0042] The lateral extension rod 2 is a hollow cylinder made of polytetrafluoroethylene (PTFE) to reduce the weight of the device and increase the rigidity of the rod. One end of the rod is threaded for assembly with the throttle lever head 1. The length of the rod is designed to be adjustable to meet the needs of different drivers and improve the ergonomic performance of the throttle lever synchronization device. Figure 4 .

The threaded part of the linkage device is installed in the third mounting hole 8 of the side throttle rod head. By adjusting the amount of screwing of the threaded part of the linkage device in the third mounting hole 8 of the side throttle rod head, the amount of insertion of the smooth rod part of the linkage device in the third mounting hole 8 of the middle throttle rod head can be changed to realize the linkage of the second and third engines or the first, second, third, and fourth throttle rods.

[0045] The rod head shaft is installed in the second mounting hole 7 of the throttle rod head by means of an interference fit. The first connecting rod 12 is a T-shaped part consisting of two cylindrical parts, one long and one short. The long cylinder is a solid cylinder with a threaded head on one side, and the short cylinder is a hollow cylinder used to connect to the rod head shaft 11. The first connecting rod 12 can rotate around the rod head shaft 11. The nut 13 is installed on the threaded part of the first connecting rod 12. By adjusting the screw-in amount of the nut, the position of the eccentric wheel 16 on the first connecting rod 12 is changed to achieve the purpose of changing the clamping force of the eccentric wheel on the throttle rod head. The appearance of the locking device is shown in FIG. Figure 6 .

[0046] Among them, the throttle rod head is divided into two parts: the middle throttle rod head and the side throttle rod head. The middle throttle rod head is installed on the throttle rod of the second engine and the throttle rod of the third engine, and the side throttle rod head is installed on the throttle rod of the first engine and the throttle rod of the fourth engine; the locking device consists of a rod head shaft, a connecting rod, a nut, and an eccentric wheel.
