[0025] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0026] like Figure 1-2 As shown in FIG. 1 , the luggage pull rod with adjustable towing angle of the utility model comprises a pull rod body 1, which is arranged on the back of a box body 2 of the luggage, and an adjustment mechanism 3 for adjusting the towing angle is arranged between the lower end of the pull rod body 1 and the lower part of the box body 2, and the adjustment mechanism 3 comprises two bearing seats 4 fixed on the left and right sides of the back of the box body 2, and a ball screw 5 is rotatably connected between the two bearing seats 4 through a bearing, and a screw slider 6 is passed through the middle of the ball screw 5, and the lower end of the pull rod body 1 is installed on the screw slider 6; The pull rod body 1, the pull rod body 1 and the screw slider 6 rotate with the ball screw 5 as the axis, so the dragging angle of the pull rod body 1 can be adjusted. The box 2 does not press on the pull rod body 1, and dragging the box 2 is more labor-saving; holding the pull rod body 1 to limit the rotation of the screw slider 6, rotating the ball screw 5, the ball screw 5 drives the screw slider 6 and the pull rod body 1 to move left and right along the axial direction of the ball screw 5, and the pull rod body 1 moves to a suitable position. When people use the pull rod body 1 to pull the box 2, it is not easy for the heel to touch the box 2, which is more convenient to use.

[0027] On the basis of the above structure, preferably, the screw slider 6 is square and close to the back of the box body 2, and the distance between the lower end surface of the screw slider 6 and the axis of the ball screw 5 is greater than the distance between the screw slider 6 and the back of the box body 2, thereby forming a rotation constraint when rotating around the ball screw 5, so that the screw slider 6 can be driven to move left and right when the ball screw 5 is driven to rotate.

[0028] As a preferred embodiment, on the basis of the above structure, preferably, a rocking handle 7 is provided at one end of the ball screw 5 to facilitate the rotation of the ball screw 5 .

[0029] As a preferred embodiment, preferably, a rotating thread hole 61 is provided at the lower portion of the screw slider 6, a mounting thread hole 62 is provided above the rotating thread hole 61, a rotating light hole 11 adapted to the rotating thread hole 61 is provided at the lower end of the pull rod body 1, and a circular arc-shaped long slot hole 12 adapted to the mounting thread hole 62 is provided above the rotating light hole 11. A bolt 63 is passed through the rotating light hole 11, and the bolt 63 is locked in the rotating thread hole 61. A gap is left between the head of the bolt 63 and the surface of the pull rod body 1. The pull rod body 1 can rotate around the bolt 63 as the axis. A handle screw 64 is passed through the circular arc-shaped long slot hole 12, and the handle screw 64 is locked in the mounting thread hole 62. After adjusting the rotation angle of the pull rod body 1, the handle screw 64 locks the pull rod body 1 on the screw slider 6. This embodiment further expands the adjustment range of the pull rod body 1.

[0030] As a preferred embodiment, preferably, the pull rod body 1 includes a pull rod frame 13, the lower end of the pull rod frame 13 is arranged on the screw slider 6, and the upper end of the pull rod frame 13 is telescopically connected to a movable rod 14. The pull rod frame 13 and the telescopic movable rod 14 are existing technologies, which are convenient for adjusting the towing height of the luggage.

[0031] As a preferred embodiment, on the basis of the above structure, preferably, a pull ring 15 is provided at the upper end of the movable rod 14 .

[0032] As a preferred embodiment, based on the above structure, preferably, an anti-slip layer 151 is provided on the surface of the pull ring 15 .

[0033] As a preferred embodiment, preferably, a threaded hole 65 is provided on the screw slider 6, and a handle screw 66 abutting against the ball screw 5 is provided in the threaded hole 65; the screw slider 6 is rotated, and the screw slider 6 drives the pull rod body 1 to rotate with the ball screw 5 as the axis. After adjusting the dragging angle of the pull rod body 1, the handle screw 66 supports the ball screw 5 to prevent the screw slider 6 from continuing to rotate.

[0034] As a preferred embodiment, preferably, a second thread hole 41 is provided on the bearing seat 4, and a handle screw three 42 abutting against the ball screw 5 is provided in the thread hole 41; when the ball screw 5 is rotated, the ball screw 5 drives the screw slider 6 and the pull rod body 1 to move axially of the ball screw 5. After the pull rod body 1 moves to a suitable position, the handle screw three 42 supports the ball screw 5 to prevent the ball screw 5 from continuing to rotate.

[0035] As a preferred embodiment, on the basis of the above structure, preferably, a universal wheel 21 is provided on the bottom surface of the box body 2 .

[0036] As a preferred embodiment, preferably, a Velcro fleece surface 8 is fixed to the upper back side of the box body 2, a Velcro hook surface 9 is provided at the corresponding position of the Velcro fleece surface 8, one end of the Velcro hook surface 9 is fixed to the box body 2, and the Velcro can assist in fixing the pull rod body 1.

[0037] The working principle of the utility model is as follows:

[0038] When the pull rod body 1 needs to be moved to the side of the box body 2, loosen the handle screw three 42 and the handle screw two 66, fix the pull rod body 1 on the screw slider 6 by locking the handle screw one 64, hold the pull rod body 1 to limit the rotation of the screw slider 6, manually rotate the shaking handle 7, and the shaking handle 7 drives the ball screw 5 to rotate. The ball screw 5 drives the screw slider 6 and the pull rod body 1 to move left and right in the axial direction of the ball screw 5. After the pull rod body 1 moves to the appropriate position, fix the left and right position of the pull rod body 1 by locking the handle screw three 42 and the handle screw two 66.

[0039] When the pull rod body 1 needs to be rotated left or right, loosen the handle screw 64, rotate the pull rod body 1 left or right to a suitable position, and then tighten the handle screw 64 to position the pull rod body 1 in the left or right direction.

[0040] When the towing angle of the luggage needs to be adjusted, loosen handle screw three 42 or handle screw two 66, fix the pull rod body 1 on the screw slider 6 by locking handle screw one 64, manually rotate the pull rod body 1, and after the pull rod body 1 is rotated forward and backward to the appropriate position, position the pull rod body 1 in the forward and backward directions by locking handle screw three 42 and handle screw two 66.

[0041] When the length of the pull rod body 1 needs to be adjusted, the length of the movable rod 14 extending from the pull rod frame 13 can be adjusted.

[0042] When in use, the rod body 1 is adjusted to a suitable position as required, and the pull ring 15 is pulled, and the pull ring 15 drives the box 2 to move. When not in use, the rod body 1 can be adjusted to be attached to the back of the box 2, and the Velcro hook surface 9 tightens the rod body 1 to fit the Velcro fur surface 8.

[0043] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
