[0017] Reference Figure 1-4, a forklift steering wheel mounting device includes a steering column 1, a steering wheel 2 is provided above the steering column 1, a mounting column 9 is fixedly connected to the bottom surface of the steering wheel 2, the outer surface of the mounting column 9 is slidably connected to the inner wall of the steering column 1, and the outer surface of the mounting column 9 is fixedly connected to four sliders 10, the outer surface of each slider 10 is slidably connected to the inner wall of the steering column 1, and a limiting cylinder 11 is provided below the mounting column 9, the upper surface of the limiting cylinder 11 contacts the bottom surface of the mounting column 9, the outer surface of the limiting cylinder 11 is slidably connected to the inner wall of the steering column 1, and the limiting cylinder The inner wall of 11 is slidably connected with four limit blocks 12, and the outer surface of each limit block 12 is slidably connected to the inner wall of the steering column 1, and the side of each group of limit blocks 12 close to each other is fixedly connected with a spring 16, and the end of each group of springs 16 close to each other is fixedly connected to the inner wall of the limit cylinder 11, and the upper surface of each limit block 12 is fixedly connected with a pull rod 18, and the outer surface of each pull rod 18 is slidably connected to the outer surface of the limit cylinder 11 and the mounting column 9, and the surface of the pull rod 18 is fixed with several limit rollers 19 slidably connected to the inner wall of the mounting column 9.

[0018] By setting the slider 10 and the pull rod 18, the connection effect between the steering wheel 2 and the steering column 1 can be further enhanced, and it can also facilitate the steering column 1 to rotate and steer. The limiting roller 19 can provide a good limiting effect when the pull rod 18 moves. At the same time, the limiting roller can roll and slide in the mounting column 9, thereby assisting the pull rod 18 in pushing and moving, effectively avoiding the situation where the upper and lower ends are tilted.

[0019] Furthermore, a connecting column 3 is fixedly connected to the upper surface of the steering wheel 2, and a hand-grip ball 4 is rotatably connected to the outer surface of the connecting column 3. By setting the connecting column 3 and the hand-grip ball 4, it is convenient for the staff to drive the steering wheel 2 to rotate through the hand-grip ball 4, thereby improving convenience during use.

[0020] Furthermore, a rubber pad 8 is fixedly connected to the bottom surface of the steering wheel 2, and the bottom surface of the rubber pad 8 is in contact with the upper surface of the steering column 1. By providing the rubber pad 8, a certain gap can be created between the steering wheel 2 and the steering column 1, thereby avoiding wear during steering.

[0021] Furthermore, a threaded head 15 is fixedly connected to the upper surface of the limiting cylinder 11, and the outer surface of the threaded head 15 is threadedly connected to the inner wall of the mounting column 9. By setting the threaded head 15, the mounting column 9 and the limiting cylinder 11 can be connected and fixed so that they can work stably.

[0022] Furthermore, the inner wall of each limit block 12 is slidably connected to the limit column 17, and the side surface of each group of limit columns 17 close to each other is fixedly connected to the inner wall of the limit cylinder 11. By setting the limit column 17, the stability of the limit block 12 can be further increased, so that it can perform the limiting work more firmly.

[0023] Furthermore, the top of each pull rod 18 is threadedly connected to a pull block 13, and each group of pull blocks 13 has anti-slip grooves 14 arranged at equal distances on the side facing away from each other. By setting the pull blocks 13 and the anti-slip grooves 14, it is convenient for the staff to pull the pull rod 18 through the pull blocks 13 to move it, thereby facilitating the staff to carry out installation and disassembly work.

[0024] Furthermore, a sealing cover 5 is commonly provided above the four pull blocks 13. The upper surface of each pull block 13 contacts the bottom surface of the sealing cover 5. The outer surface of the sealing cover 5 is threadedly connected to the inner wall of the steering wheel 2. By providing the sealing cover 5, the center position of the steering wheel 2 can be sealed and protected, and the aesthetics of the device can also be improved.

[0025] Furthermore, a handle 6 is fixedly connected to the upper surface of the sealing cover 5, and an anti-slip sleeve 7 is fixedly connected to the outer surface of the handle 6. By providing the handle 6 and the anti-slip sleeve 7, the sealing cover 5 can be easily pulled out by the handle 6, thereby facilitating use by the staff.

[0026] When the device is used, the staff first brings the device to a suitable position for use. When the staff needs to install the steering wheel 2 of the forklift, the staff first removes the sealing cover 5 from the steering wheel 2 through the handle 6, and manually moves the pull block 13 to the inside of the steering wheel 2. When the pull block 13 moves, it can drive the pull rod 18 below to move. During the movement of the pull rod 18, it can drive the limit block 12 to move and shrink. When the limit block 12 moves, it can squeeze the spring 16, so that the installation column 9 and the limit cylinder 11 can be inserted into the steering column 1 through the slider 10. The slider 10 can facilitate the staff to install the installation column 9 and the limit cylinder at the bottom of the steering wheel 2. The limiting cylinder 11 is introduced into the interior of the steering column 1, and at the same time, it can increase the limiting effect between the steering column 1 and the steering wheel 2, so that it can better drive the steering column 1 to rotate and steer until the limiting block 12 moves to the groove inside the steering column 1. The limiting block 12 will be bounced to the interior of the steering column 1 for installation and fixation under the elastic force of the spring 16, so that the steering wheel 2 can be quickly disassembled and assembled without using tools, thereby improving the efficiency of the staff's disassembly and assembly. At the same time, the limiting column 17 inside the limiting block 12 can increase the overall stability of the limiting block 12, so that it can be used stably, thereby improving the practical effect of the device.
