DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the toothed plate type column angle adjustment mechanism involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0025] The present invention provides a toothed plate type pipe column angle adjustment mechanism, comprising:

[0026] Adjustment handle mechanism 130: The adjustment handle mechanism 130 includes an adjustment handle 1301 in a locked state and an adjustment handle 1302 in a released state, which are used to distinguish between two different states of the adjustment handle mechanism 130;

[0027] Pipe column body 190: The adjustment handle mechanism 130 is used to adjust the angle of the pipe column body 190;

[0028] Locking blocks 160: The two locking blocks 160 cooperate with each other through claw engagement;

[0029] Main tooth plate 110: used to limit the angle adjustment of the pipe column body 190;

[0030] Auxiliary tooth plate 120: used for contacting and locking with the main tooth plate 110 through the teeth;

[0031] A locking bolt 140 is threadedly sleeved on the middle part of the pipe column body 190, a locking nut 150 is threadedly sleeved on one end of the locking bolt 140, a dust cover 170 is fixedly connected to the inner side of the locking nut 150, a secondary tooth plate 120 is fixedly connected to the inner side of the dust cover 170, the outer wall of the secondary tooth plate 120 is movably engaged with the main tooth plate 110, and the outer wall of the main tooth plate 110 is fixedly connected to the pipe column body 190.

[0032] Furthermore, a locking block 160 is fixedly connected to the outer wall of the locking bolt 140 near the other side, and another locking block 160 is engaged with a claw on one side of the outer wall of one locking block 160, so that when the two locking blocks 160 are engaged and rotated, the two locking blocks 160 increase the matching distance through the claw engagement, thereby driving the locking bolt 140 to move outward.

[0033] Furthermore, an outer wall of a locking block 160 is fixedly sleeved with an adjusting handle mechanism 130. When the adjusting handle mechanism 130 is in the locking state and the adjusting handle 1301 is in the locked state, the main tooth plate 110 and the auxiliary tooth plate 120 are engaged with each other, so as to limit and fix the column body 190 when the angle is not adjusted.

[0034] Furthermore, a tooth plate spring piece 180 is fixedly connected to the middle part of the opposite side of the auxiliary tooth plate 120 and the main tooth plate 110, and one end of the tooth plate spring piece 180 is in contact with the opposite side of the main tooth plate 110, so that when the adjustment handle mechanism 130 is adjusted to the position of the adjustment handle 1302 in the loosened state, the locking block 160 is driven to rotate, and the two locking blocks 160 are engaged by claws to reduce the matching distance, and the tooth plate spring piece 180 pops open to push the auxiliary tooth plate 120 to move outward, and the auxiliary tooth plate 120 pushes the dust cover 170 to move outward, and the dust cover 170 pushes the locking nut 150 to move outward, and the locking nut 150 drives the locking bolt 140 to move and loosen.

[0035] Furthermore, when the adjustment handle mechanism 130 is in the locking state of the adjustment handle 1301, the angle adjustment holding force of the pipe column can reach more than 800N through the meshing and locking of the main tooth plate 110 and the auxiliary tooth plate 120, which is convenient for achieving a large holding force of the pipe column when it is not rotating.

[0036] Furthermore, one side of the dust cover 170 is fixedly connected to one side of the inner wall of the locking nut 150, and the other side of the dust cover 170 is fixedly connected to one side of the outer wall of the auxiliary gear plate 120. The dust cover 170 is movably sleeved on the outer wall of the locking bolt 140, so that under the action of the dust cover 170, the contact between the interior of the pipe column body 190 and the outside world can be provided with a certain dust-proof protection effect, thereby facilitating the improvement of the service life of the pipe column body 190.

[0037] Working principle of the present invention: When in use, the adjusting handle mechanism 130 in the pipe column adjusting mechanism has two states: the adjusting handle 1301 in the locked state and the adjusting handle 1302 in the loosened state. When the adjusting handle mechanism 130 changes from the adjusting handle 1302 in the loosened state to the adjusting handle 1301 in the locked state, the adjusting handle mechanism 130 drives the locking block 160 to rotate, and the two locking blocks 160 increase the matching distance through the claw engagement, driving the locking bolt 140 to move outward. Figure 2The force generated in is transmitted to the locking nut 150 through the locking bolt 140, and the locking nut 150 pushes the dust cover 170 to move inward, and the dust cover 170 pushes the auxiliary tooth plate 120 to move inward, and the auxiliary tooth plate 120 contacts and engages with the main tooth plate 110 through the teeth and is locked. When the adjusting handle mechanism 130 changes from the adjusting handle 1301 in the locked state to the adjusting handle 1302 in the loosened state, the adjusting handle mechanism 130 drives the locking block 160 to rotate, and the two locking blocks 160 reduce the matching distance through the claw engagement, and the tooth plate spring piece 180 pops open to push the auxiliary tooth plate 120 to move outward, and the auxiliary tooth plate 120 pushes the dust cover 170 to move outward, and the dust cover 170 pushes the locking nut 150 to move outward, and the locking nut 150 drives the locking bolt 140 to move and loosen.
