DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-4 , the utility model provides an embodiment: a steering column locking structure, comprising a steering column 1, the outer sleeve of the steering column 1 is provided with a sleeve column 2;

[0026] Also includes:

[0027] A U-shaped arc groove 3 is arranged on the outer wall of one side of the sleeve column 2, and an arc-shaped curved piece 4 is arranged inside the U-shaped arc groove 3, and an integrated plate 12 is welded on the outer wall of the arc-shaped curved piece 4;

[0028] A reference nut 8 is welded and arranged at the center of one end of the integrated plate 12, and an abutment nut 11 is arranged on one side of the reference nut 8;

[0029] The base block 5 is arranged on the other side of the integrated plate 12, and the base block 5 and the integrated plate 12 are internally connected and movable with an internal connecting shaft 6;

[0030] A threaded end 7 is arranged at one end of the inner connecting shaft 6, and the threaded end 7 and the inner connecting shaft 6 are an integral structure;

[0031] The slideway 13 is arranged on one side of the sleeve column 2, and an inner connecting slider 14 is arranged inside the slideway 13 for sliding up and down. A connecting rod 15 is arranged between the inner connecting slider 14 and the sleeve column 2, and the two ends of the connecting rod 15 are respectively welded to the inner connecting slider 14 and the sleeve column 2.

[0032] See also Figure 4 A connecting spring 10 is arranged between the base block 5 and the integrated plate 12, and the two ends of the connecting spring 10 are respectively welded to the base block 5 and the integrated plate 12. The connecting spring 10 arranged between the base block 5 and the integrated plate 12 plays the role of elastically connecting the base block 5 and the integrated plate 12.

[0033] See also Figure 4 A turning handle 9 is arranged at one end of the inner connecting shaft 6, and the turning handle 9 and the inner connecting shaft 6 are an integrated structure. The turning handle 9 arranged at one end of the inner connecting shaft 6 plays a role in driving the inner connecting shaft 6 to rotate forward and reversely to adjust the tightness.

[0034] See also Figure 4 The abutting nut 11 is fixedly connected to the inner connecting shaft 6 through the threaded end 7.

[0035] See also Figure 4 , the abutting nut 11 is in contact and abutting connection with the reference nut 8 .

[0036] Working principle: When locking the steering column 1, the inner connecting shaft 6 is driven to guide the position of the base block 5 by turning the handle 9 forward, so that the threaded end 7 is guided along the reference nut 8 and the integrated plate 12, thereby pulling the pre-installed abutment nut 11 to abut and press against the reference nut 8 and the integrated plate 12. Since the reference nut 8, the integrated plate 12 and the arc-shaped bent piece 4 are welded one-piece structures, after abutment and pressing, the arc-shaped bent piece 4 contacts the steering column 1 inside the friction sleeve column 2, thereby locking the steering column 1 and restricting further rotation. When the locking state needs to be released, it is only necessary to reverse the handle 9. The operation is simple and the locking operation is convenient. After the locking state is released, the inner connecting slider 14 is connected to the up and down sliding connection of the slideway 13, so that the sleeve column 2 can only move up and down along the slideway 13, avoiding the sleeve column 2 from shaking, and completing the practical work of the steering column locking structure.
