Description

Technical Field

[0001] This utility model relates to a joystick, specifically a foldable joystick, belonging to the field of excavator joystick technology. Background Technology

[0002] Excavators are a common type of engineering machinery, mainly used in earthmoving projects, such as excavating soil, sand, gravel, and ore. They are also commonly used in construction, often for foundation excavation or trench excavation. The joystick is the main tool for excavator operators to control the excavator. By moving the joystick differently, operators can control various functions of the excavator.

[0003] However, in real life, we can see that, especially for some excavators with relatively compact internal space, if the control lever cannot be folded after use, the height of the control lever will make it inconvenient for the operator to enter and exit the cab. Utility Model Content

[0004] This invention proposes a foldable control lever to solve the problem that the inability of the control lever to fold causes inconvenience for operators when entering and exiting the driver's cab.

[0005] This utility model is achieved through the following technical solution: a foldable control lever, including two first control levers, a second control lever is provided above each of the two first control levers, and a folding adjustment mechanism is provided on the outer surface of each of the two first control levers. The folding adjustment mechanism includes an L-shaped fixing handle one, a connecting bushing is fixedly connected to the inner wall of the L-shaped fixing handle one, and an L-shaped fixing handle two is rotatably connected to the outer surface of the connecting bushing. An adjustment limiting hole is opened on the outer surface of the L-shaped fixing handle two.

[0006] A connecting rod is slidably connected to the inner wall of the connecting bushing. An arc-shaped button is fixedly connected to the top end of the connecting rod. A connecting plate is fixedly connected to the bottom end of the connecting rod. A symmetrical limiting post is fixedly connected to the outer surface of the connecting plate. A spring is fixedly connected to the outer surface of the arc-shaped button.

[0007] Furthermore, the first L-shaped fixing handle is fixedly connected to the outer surface of the first control lever, and the second L-shaped fixing handle is fixedly connected to the outer surface of the second control lever. The first control lever can provide support for the first L-shaped fixing handle, and the second L-shaped fixing handle can connect the second control lever and the first control lever.

[0008] Specifically, the limiting post is adapted to the adjusting limiting hole, and the spring is fixedly connected to the connecting bushing. By inserting the limiting post into the adjusting limiting hole, the adjusting limiting hole can be limited.

[0009] Furthermore, each of the two second control levers is fixedly connected to a push-pull handle at its top end. The outer surface of each push-pull handle is provided with anti-slip texture. By providing push-pull handles, people can push the second control levers more conveniently.

[0010] Preferably, the first control lever and the second control lever are adapted to each other, and the spring is sleeved on the outer surface of the connecting rod. When the top end of the first control lever is in contact with the bottom end of the second control lever, the first control lever and the second control lever are in a straight line state.

[0011] This utility model provides a foldable joystick, which has the following beneficial effects:

[0012] The foldable control lever, through the coordinated arrangement of the first control lever, the second control lever, and the folding adjustment mechanism, allows the excavator to fold the first and second control levers when not in use, thereby providing more space for the operator to enter and exit the cab, making it easier for the operator to get in and out of the cab.

[0013] This foldable control lever, through the coordinated arrangement of an arc-shaped button, connecting rod, connecting plate, limiting post, connecting bushing, L-shaped fixing handle one, L-shaped fixing handle two, and the second control lever, allows operators to easily fold the first and second control levers. By pressing the connecting rod with the arc-shaped button until the limiting post disengages from the adjusting limiting hole, and then flipping the second control lever to 180 degrees, the limiting post aligns with the adjusting limiting hole. By releasing the arc-shaped button, the limiting post can be inserted into the adjusting limiting hole under the elastic force of the spring, thereby realizing the folding of the first and second control levers.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-4 This utility model embodiment provides a foldable control lever, including two first control levers 1, which are mounted on the excavator body. By swinging the first control levers 1 back and forth, multiple functions of the excavator can be controlled. A second control lever 2 is provided above each of the two first control levers 1. A folding adjustment mechanism 3 is provided on the outer surface of each of the two first control levers 1. By providing the folding adjustment mechanism 3, the first control levers 1 and the second control lever 2 can be folded when the excavator is not working. The folding adjustment mechanism 3 includes an L-shaped fixing handle 301, a connecting bushing 302 is fixedly connected to the inner wall of the L-shaped fixing handle 301, and an L-shaped fixing handle 303 is rotatably connected to the outer surface of the connecting bushing 302. The L-shaped fixing handle 303 can rotate around the connecting bushing 302. An adjustment limit hole 304 is provided on the outer surface of the L-shaped fixing handle 303.

[0024] A connecting rod 305 is slidably connected to the inner wall of the connecting bushing 302. The connecting rod 305 passes through the connecting bushing 302. An arc-shaped button 306 is fixedly connected to the top of the connecting rod 305. The arc-shaped button 306 allows people to press the connecting rod 305 more comfortably.
