[0033] Reference Figures 1 to 9 The utility model provides an automobile steering mechanism: comprising two fixing seats 1, each of which has two fixing holes on its upper surface, and a steering gear body 2 fixedly connected to the upper surfaces of the two fixing seats 1, and a direction rod 11 fixedly connected to the ends of the steering gear body 2 away from each other, and a dust cover 12 fixedly connected to each direction rod 11, and the other end of each dust cover 12 is fixedly connected to the corresponding end of the steering gear body 2, and the dust cover 12 can prevent dust from entering the interior of the steering gear body 2, and a threaded groove is provided at one end of each direction rod 11, and each threaded groove is threadedly connected to A locking nut 14 is provided, and an outer ball head 13 is threadedly connected to each thread groove. A rotating shaft 3 is fixedly connected to the steering shaft of the steering gear body 2. A fixing hole is provided on one side of the rotating shaft 3. An outer sleeve column 4 is movably connected to the outer wall of the rotating shaft 3. A rotating groove is provided on the outer wall of the outer sleeve column 4. A quick-release structure 10 is provided in the rotating groove. One end of the outer sleeve column 4 is fixedly connected to a first universal joint 5.

One side of the second universal joint 7 is fixedly connected to a steering column 8. One end of the steering column 8 is fixedly connected to a steering wheel 9.

[0034] In order to achieve the purpose of quick disassembly and assembly, the quick-disassembly structure 10 includes a rotating ring 101 rotatably connected in the rotating groove, one side of the rotating ring 101 is fixedly connected to a fixed frame 102, an upper side of the fixed frame 102 is fixedly connected to a fixed plate 103, one side of the fixed plate 103 is movably connected with a sliding rod 104, one end of the sliding rod 104 is fixedly connected to a rotating column 105, the other end of the sliding rod 104 is fixedly connected to a clamping column 106, a spring 107 is movably provided on the sliding rod 104, one end of the spring 107 is fixedly connected to an inner side of the fixed frame 102, and the other end is fixedly connected to one side of the clamping column 106, one end of the clamping column 106 is slidably connected to the rotating ring 101 and the outer sleeve column 4, the clamping column 106 is adapted to the fixing hole, and the rotating column 105 is rotated. The column 105 drives the sliding rod 104 to rotate, and the sliding rod 104 drives the two limiting columns 108 to rotate. The two limiting columns 108 rotate from one side of the corresponding fan-shaped groove 1010 to the other side, and coincide with the corresponding limiting groove 109. Then the sliding rod 104 is pulled, and the sliding rod 104 drives the two limiting columns 108 to disengage from the limiting groove 109, and at the same time drives the clamping column 106 to disengage from the fixing hole. Then the rotating ring 101 is rotated to loosen the rotating column 105. Under the elasticity of the spring 107, one end of the clamping column 106 is pressed against the inner side of the rotating groove. Then the outer sleeve column 4 is pulled out to separate the outer sleeve column 4 from the rotating shaft 3. There is no need to remove the bolts, so as to avoid the small space at the connection between the steering gear body 2 and the first universal joint 5. It is difficult for the staff to use tools to disassemble and install the bolts, which affects the disassembly and assembly efficiency of the steering gear body 2.

The outer sleeve post 4 is sleeved on the rotating shaft 3, and then the rotating ring 101 is rotated to make the clamping post 106 coincide with the fixing hole. Then, under the elasticity of the spring 107, the clamping post 106 is clamped close to the fixing hole. At the same time, the two limiting posts 108 slide into the corresponding fan-shaped grooves 1010 through the limiting grooves 109, and then the rotating post 105 is rotated. The rotating post 105 drives the two limiting posts 108 to rotate from one side of the fan-shaped groove 1010 to the other side through the sliding rod 104, limiting the sliding rod 104, which is conducive to reducing the probability of the sliding rod 104 accidentally driving the clamping post 106 out of the fixing hole.

[0036] Working principle: rotate the rotating column 105, the rotating column 105 drives the sliding rod 104 to rotate, the sliding rod 104 drives the two limiting columns 108 to rotate, the two limiting columns 108 rotate from one side of the corresponding fan-shaped groove 1010 to the other side, and overlap with the corresponding limiting groove 109, then pull the sliding rod 104, the sliding rod 104 drives the two limiting columns 108 to disengage from the limiting groove 109, and at the same time drives the clamping column 106 to disengage from the fixing hole, then rotate the rotating ring 101, loosen the rotating column 105, and under the elasticity of the spring 107, make one end of the clamping column 106 rest on the inner side of the rotating groove, then pull out the outer sleeve column 4, so that the outer sleeve column 4 is separated from the rotating shaft 3, without removing the bolts, to avoid the steering machine body 2 and the first universal joint 5 The space at the connection is small, and it is difficult for workers to use tools to disassemble and assemble the bolts, which affects the disassembly and assembly efficiency of the steering gear body 2. When installing the steering gear body 2, put the outer sleeve column 4 on the rotating shaft 3, and then rotate the rotating ring 101 to make the clamping column 106 coincide with the fixing hole. Then, under the elasticity of the spring 107, the clamping column 106 is clamped close to the fixing hole. At the same time, the two limit columns 108 slide into the corresponding fan-shaped groove 1010 through the limit groove 109, and then rotate the rotating column 105. The rotating column 105 drives the two limit columns 108 to rotate from one side of the fan-shaped groove 1010 to the other side through the sliding rod 104, limiting the sliding rod 104, which helps to reduce the probability of the sliding rod 104 accidentally driving the clamping column 106 out of the fixing hole.
