In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] See Figure 1 and Figure 2To describe this embodiment, the present utility model provides a dust-proof pull rod control structure for the landing gear of a simulator. The dust-proof pull rod control structure for the landing gear of the simulator includes a fixed plate 1, a control rod 2, a first limit plate 3, a second limit plate 4, a trigger rod 7, a positioning rod 8, a first microswitch 5 and a second microswitch 6. The fixed plate 1 is provided with a first long hole 101. Two limit grooves 102 are spaced on the lower surface of the fixed plate 1. The two limit grooves 102 are arranged in parallel and have the same depth. The control rod 2 passes through the first long hole 101 and can slide along the extension direction of the first long bar. The extension direction of the first long hole 101 is the same as the extension direction of the limit groove 102. The first limit plate 3 and the second limit plate 4 are respectively inserted into the two limit grooves 102. The first limit plate 3 and the second limit plate 4 are respectively provided with a first limit hole 31 and a second limit hole 41. The trigger rod 7 and the positioning rod 8 are both fixedly connected to the control rod 2. The trigger rod 7 and the positioning rod 8 are both perpendicular to the control rod 2. The trigger rod 7 and the positioning rod 8 respectively slide through the first limit hole 31 and the second limit hole 41. The trigger rod 7 slides in the first limit hole 31 with a first position and a second position, both fixedly arranged on the first limit plate 3. When the trigger rod 7 is in the first position, the trigger rod 7 triggers the first microswitch 5. When the trigger rod 7 is in the second position, the trigger rod 7 triggers the second microswitch 6.

[0045] In this dust-proof pull rod control structure for the landing gear of the simulator, the control rod 2 can swing back and forth in the first long hole 101. The control rod 2, the trigger rod 7 and the positioning rod 8 are all fixedly connected. The control rod 2 drives the trigger rod 7 and the positioning rod 8 to move. The trigger rod 7 will slide in the first limit hole 31. When the trigger rod 7 slides to the first position, the trigger rod 7 will touch the contact of the first microswitch 5 and trigger the first microswitch 5. When the trigger rod 7 slides to the second position, the trigger rod 7 will touch the contact of the second microswitch 6 and trigger the second microswitch 6. Triggering the first microswitch 5 or the second microswitch 6 can generate an electrical signal, thereby realizing the switch function of the simulated landing gear.

[0046] In this dust-proof pull rod control structure for the landing gear of the simulator, the positioning rod 8 is also set to slide in the second limit hole 41 along with the swing of the control rod 2, which can make the movement of the control rod 2 more stable. Two limit grooves 102 are spaced on the lower surface of the fixed plate 1. The two limit grooves 102 are arranged in parallel and have the same depth. The first limit plate 3 and the second limit plate 4 are respectively inserted into the two limit grooves 102, which can facilitate the installation of the first limit plate 3 and the second limit plate 4 on the fixed plate 1 and ensure accurate positioning. Thus, the positions of the first limit hole 31 and the second limit hole 41 are determined conveniently and accurately, enabling the trigger rod 7 and the positioning rod 8 to correspond to the first limit hole 31 and the second limit hole 41 respectively, and allowing the trigger rod 7 to slide smoothly in the first limit hole 31 while the positioning rod 8 can also slide smoothly in the second limit hole 41. The phenomenon of jamming or trigger failure during the swing of the control rod 2 is eliminated, making it more precise and durable.

[0047] In this embodiment, the first limiting plate 3 and the second limiting plate 4 are also fixedly connected to the fixed plate 1 by bolts. Now, the first limiting plate 3 and the second limiting plate 4 are respectively inserted into the two limiting slots 102 of the fixed plate 1, and then the first limiting plate 3 and the second limiting plate 4 are fixedly connected to the fixed plate 1 by bolts.

[0048] In this embodiment, the trigger rod 7 and the positioning rod 8 both penetrate into the mounting hole of the operating rod 2 and are screwed tightly for connection.

[0049] Optionally, both the first limiting hole 31 and the second limiting hole 41 are in an "n" shape. The first position of the trigger rod 7 is located at the lower left corner of the first limiting hole 31, and the second position of the trigger rod 7 is located at the lower right corner of the first limiting hole 31. Setting the shapes of the first limiting hole 31 and the second limiting hole 41 in this way can prevent accidental touch of the first microswitch 5 or the second microswitch 6, because when the operating rod 2 moves from one position to another position, the operating rod 2 needs to be lifted and then swung to the other side and put down to reach the other position, and the operating rod 2 cannot be swung without lifting the operating rod 2.

[0050] Optionally, the simulator landing gear dust-proof pull rod operating structure further includes a positioning post 10. The operating rod 2 is provided with a second long hole 21 which extends along the extending direction of the operating rod 2. The positioning post 10 slidably penetrates through the second long hole 21, and both ends of the positioning post 10 are fixedly connected to the first limiting plate 3 and the second limiting plate 4 respectively. The positioning structure enables the operating rod 2 to move up and down but not to rotate. After the positioning post 10 penetrates into the second long hole 21, the operating rod 2 can move along its own extending direction but cannot rotate in the circumferential direction. In this embodiment, one end of the positioning post 10 is provided with an abutting cap, and the other end is provided with an external thread. The positioning post 10 penetrates through the second limiting plate 4, the operating rod 2 and the first limiting plate 3 in sequence. The abutting cap abuts against the second limiting plate 4, and a gasket is sleeved on the other end of the positioning post 10 protruding from the first limiting post 10 and is screwed with a nut.

[0051] Optionally, the simulator landing gear dust-proof pull rod operating structure further includes a spring-back structure. The spring-back structure includes a fixing screw 91, a compression spring 92, a first abutting structure and a second abutting structure. The first abutting structure is fixedly connected to the fixing screw 91. The fixing screw 91 is screwed to the lower part of the operating rod 2 and has the same extending direction as the operating rod 2. The second abutting structure is fixedly connected to the positioning post 10. The compression spring 92 is sleeved on the fixing screw 91, and both ends of the compression spring 92 abut against the first abutting structure and the second abutting structure respectively. When the operating rod 2 is lifted upward, the compression spring 92 is compressed. When the trigger rod 7 moves to one end of the first limiting hole 31, the operating rod 2 is released, and under the action of the elastic force of the compression spring 92, the operating rod 2 will fall and trigger the microswitch. It can increase the feel of the operator and also lock the operating rod 2 in the first position or the second position.

[0052] Optionally, the second abutting structure includes a slider 93 and two positioning inner sleeves 94. The joystick 2 slidably penetrates through the slider 93. The two positioning inner sleeves 94 are located on opposite sides of the slider 93. A part of each positioning inner sleeve 94 is inserted into the slider 93. The two positioning inner sleeves 94 are fixedly sleeved on the positioning column 10. The upper part of the compression spring 92 abuts against the slider 93. The positioning inner sleeve 94 can fixedly connect the positioning column 10 and the slider 93. The joystick 2 can slide within the slider 93, and the slider 93 does not hinder the movement of the joystick 2. The upper part of the compression spring 92 abuts against the slider 93.

[0053] Optionally, the first abutting structure is an abutting gasket 95. The abutting gasket 95 is sleeved on the fixing screw 91. The lower part of the compression spring 92 abuts against the abutting gasket 95. The abutting gasket 95 provides an abutting position for the lower end of the compression spring 92.

[0054] Optionally, the simulator landing gear dust-proof pull rod control structure further includes a fixing nut 96. The fixing nut 96 is screwed to the fixing bolt 91. The fixing nut 96 abuts against the lower end of the joystick 2. The fixing nut 96 can determine the depth of the fixing bolt 91 extending into the joystick 2, thereby adjusting the pressure of the compression spring 92.

[0055] Optionally, the simulator landing gear dust-proof pull rod control structure further includes a dust-proof cover 12. The dust-proof cover 12 is fixedly arranged on the joystick 2. The dust-proof cover 12 is fixedly connected to the joystick 2 and is located above the fixing plate 1, which can prevent foreign objects from falling into the structure.

[0056] Optionally, the simulator landing gear dust-proof pull rod control structure further includes a handle 13. The handle 13 is fixedly arranged on the upper part of the joystick 2. It is convenient for the operator to grip the joystick 2. Optionally, the handle 13 is provided with anti-slip lines. It can increase the friction between the operator's hand and the handle 13, playing an anti-slip role and preventing the palm from sweating or being difficult to grip in other situations. In this embodiment, the handle 13 is connected to the joystick 2 by bolts.

[0057] Optionally, the simulator landing gear dust-proof pull rod control structure further includes a support column 11. The two ends of the support column 11 are respectively fixedly connected to the first limiting plate 3 and the second limiting plate 4. In this embodiment, the number of support columns 11 is four, and the four support columns 11 are respectively located at the four corners of the first limiting plate 3.
