[0002] Luggage is a general term for bags, which is a general term for various bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags and various trolley cases. The trolleys of luggage can only be retracted, and an adjustment device is required to adjust the angle of the trolley for the convenience of users.
[0003] For example, a luggage trolley with publication number "CN109043785A" utilizes a telescopic flip link movably connected to the inner side of a bottom flip frame. The telescopic flip link is inserted into a longitudinal assembly slot to flexibly connect to the main case. This allows the trolley to maintain the position and angle of the case when flipped, greatly improving the stability of the case and facilitating its movement. However, the telescopic trolley itself only has a telescopic function and cannot be adjusted for the pulling angle, making it inconvenient for users. Furthermore, after a period of travel, the user needs to manually open the case lid, which consumes a lot of physical strength and increases the user's labor. Utility Model Content

DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] Refer to the attached Figure 1-5 : In this embodiment, a luggage pull rod with adjustable dragging angle includes a luggage 1 and a first pull rod 9. The inner wall of the luggage 1 is slidably connected to the first pull rod 9. An automatic lid opening mechanism 8 is provided inside the luggage 1. An adjustment mechanism 2 is provided inside the first pull rod 9. A box lid 4 is hinged on the front side of the luggage 1. A plurality of self-locking universal wheels 5 are installed at the bottom of the luggage 1. A button 6 is installed on the right side of the luggage 1. The button 6 can control the buckling switch between the box lid 4 and the luggage 1. It is a relatively mature existing technology and will not be elaborated here. A first handle 7 is fixedly connected to the right end of the luggage 1, and a second handle 3 is fixedly connected to the upper end of the luggage 1.
[0021] The adjusting mechanism 2 includes a worm 201, both ends of which are rotatably connected to the first pull rod 9 through bearings, the outer wall of the worm 201 is meshed with the worm wheel 202, the outer side of the worm wheel 202 transmission shaft is rotatably connected to the first pull rod 9 through bearings, the inner side of the worm wheel 202 transmission shaft is fixedly connected with a first gear 203, the inner side of the first gear 203 transmission shaft is rotatably connected to the first pull rod 9 through bearings, the first gear 203 is meshed with the second gear 204, both sides of the second gear 204 transmission shaft are rotatably connected to the first pull rod 9 through bearings, the inner side of the second gear 204 transmission shaft is fixedly connected to the second pull rod 205, the rotation of the worm 201 drives the worm wheel 202 to rotate, thereby driving the first gear 203 to rotate, the rotation of the first gear 203 drives the second gear 204 to rotate, thereby driving the second pull rod 205 to rotate.
[0022] The automatic lid opening mechanism 8 includes a gas spring 801 and a baffle 804. The inner side of the gas spring 801 is fixedly connected to a rotating rod 802. The model of the gas spring 801 can be selected according to actual needs to meet the work needs. The rotating rod 802 is rotatably connected to the luggage 1 through a bearing. The output end of the gas spring 801 is movably connected to the fixed block 803 through a pin shaft. The outer wall of the fixed block 803 is fixedly connected to the box cover 4. The end of the worm 201 is fixedly connected to the rotating handle. The outer wall of the baffle 804 is fixedly connected to the luggage 1. The baffle 804 can prevent the items placed in the luggage 1 from contacting the gas spring 801.
[0023] Working principle:
[0024] For bags with adjustable towing angle handles:
[0025] Preparation process:
[0026] The user pulls the first pull rod 9 upwards, and stops pulling the first pull rod 9 when the first pull rod 9 moves to a position convenient for the user to use.
[0027] Second tie rod adjustment process:
[0028] The user rotates the handles on both sides at the same time. The rotation of the handles drives the worm 201 to rotate. The rotation of the worm 201 drives the worm wheel 202 to rotate, thereby driving the first gear 203 to rotate. The rotation of the first gear 203 drives the second gear 204 to rotate, thereby driving the second pull rod 205 to rotate. When the second pull rod 205 is rotated to a point where it is convenient for the user to drag the luggage 1, the rotation of the handle is stopped to achieve an adjustable angle of the second pull rod 205, which is convenient for the user to use the luggage 1. The user pulls the second pull rod 205 to drive the self-locking universal wheel 5 to rotate, which is convenient for the user to move the luggage 1. The first handle 7 and the second handle 3 are used to facilitate the operator to lift the luggage 1.
[0029] Box cover opening process:
[0030] When the box cover 4 needs to be operated, the user presses the button 6 on the suitcase 1 to separate the box cover 4 from the suitcase 1. The output end of the gas spring 801 extends to push the box cover 4 open, so that the user does not need to expend much physical strength when opening the box cover 4, thereby saving manual labor. When the box cover 4 needs to be closed, the user only needs to press the box cover 4 down hard. When the button 6 pops out, the box cover 4 and the suitcase 1 are in a locked state and cannot be opened.
[0031] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
