Description

Technical Field

[0001] The utility model relates to the technical field of luggage wheels, in particular to a quick-detachable luggage wheel. Background Art

[0002] In order to improve the stability of the luggage during the movement, the luggage wheels currently on the market are generally equipped with double-row wheels at the bottom of the box body, and the two ends of the rotating shaft of the double-row wheels are respectively equipped with rotating wheels. In order to prevent the luggage wheels from occupying too much volume, the thick bottom of the rotating wheel is generally thinner than that of a single wheel, thereby weakening the strength of the rotating wheel. When the luggage wheels are subjected to a large impact from the outside, the rotating wheel is prone to deformation or even cracking. Since the rotating wheel is generally integrated with the rotating shaft, when the rotating wheel needs to be replaced, it is necessary to use tools to saw off the connection between the damaged luggage wheel and the rotating shaft, and then replace it with a new luggage wheel. The replacement process is cumbersome, which causes great inconvenience to the users of the luggage. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4As shown, a quick-detachable luggage wheel includes a bracket 1 and a roller 2, and detachable rollers 2 are provided on both sides of the bracket 1. A second bearing sleeve 141 matching the rotating shaft is provided at the bottom of the bracket 1, and the two ends of the rotating shaft are fixedly connected to the hub 15. A conical platform 153 is provided on the side of the hub 15 away from the second bearing sleeve 141, and the roller 2 is provided with a groove 22 matching the conical platform 153; the roller 2 is detachably connected to the hub 15. The detachable roller 2 is easy to disassemble and assemble. Through the cooperation of the conical platform 153 and the groove 22, it is easy to quickly confirm the relative position of the hub 15 and the roller 2, thereby improving the efficiency of disassembling and assembling the roller 2.

[0021] A plurality of evenly spaced positioning blocks 152 are provided on the circumference of the wheel hub 15, and a positioning groove 221 is provided on the roller 2 to cooperate with the positioning blocks 152. The circumferential positions of the wheel hub 15 and the roller 2 are determined by the cooperation between the positioning blocks 152 and the positioning grooves 221, and it is convenient for the wheel hub 15 to apply torque to the roller 2. A threaded hole 151 is provided on the wheel hub 15, and a through hole 222 is provided at a position of the roller 2 corresponding to the threaded hole 151. A fastening screw 21 is provided in the through hole 222, and the fastening screw 21 passes through the through hole 222 and is screwed into the threaded hole 151. The roller 2 is fixedly connected to the roller 2 by the fastening screw 21, which facilitates the installation and disassembly of the roller 2.

[0022] The top of the bracket 1 is provided with a connecting block 11, which is a polygon, and the bottom of the bracket 1 is rotatably connected to the connecting block 11 through a first bearing sleeve 12. The bracket 1 can make a 360° rotational movement relative to the connecting block 11 through the first bearing sleeve 12, thereby improving the flexibility of the overall steering of the luggage wheel. The bracket 1 is fixedly connected to the box body through the connecting block 11, and the box body is provided with an inner groove that matches the connecting block 11. The cooperation between the connecting block 11 and the inner groove can quickly determine the relative position of the bracket 1 and the box body. The connecting block 11 is provided with a plurality of evenly spaced positioning holes, and the positioning holes are provided with screws, which pass through the positioning holes and are screwed into the box body. The luggage wheel as a whole is fixedly connected to the box body through the connecting block 11. When the luggage wheel as a whole is severely damaged, the luggage wheel as a whole can be disassembled and replaced by disassembling the screws on the positioning block 152.

[0023] A bottom shell 13 is provided at the bottom of the bracket 1, and a side cover 131 is provided above the bottom shell 13 corresponding to the roller 2. The bottom shell 13 protects the components below the bracket 1. The side cover 131 is located above the roller 2 and protects the roller 2. The interior of the bracket 1 is hollow, and a slidingly connected telescopic rod 14 is provided at the bottom of the bracket 1. One end of the telescopic rod 14 extends into the interior of the bracket 1, and the other end is fixedly connected to the second bearing sleeve 141. A spring 132 is provided at the top of the telescopic rod 14, and the other end of the spring 132 contacts the upper end of the bracket 1. When the roller 2 is impacted, the telescopic rod 14 moves up along the bracket 1 and compresses the spring 132, and the elastic deformation of the spring 132 is used to buffer the impact potential energy of the luggage wheel as a whole, thereby improving the impact resistance of the luggage wheel. A buffer pad 16 is provided at one end of the telescopic rod 14 close to the second bearing sleeve 141, and the buffer pad 16 fits the bottom end of the bracket 1. Under the action of the buffer pad 16, the lower end of the telescopic rod 14 is prevented from rigidly colliding with the bracket 1, and a buffer space is provided between the telescopic rod 14 and the bracket 1 during the movement of the telescopic rod 14.

[0024] The working principle of the specific implementation of the utility model is as follows: when the roller 2 needs to be replaced, the old roller 2 can be removed by loosening the fastening screw 21 on the end face of the roller 2, and the roller 2 and the wheel hub 15 can be quickly kept coaxial through the cooperation of the conical platform 153 and the groove 22. The wheel hub 15 is provided with a positioning block 152 that matches the roller 2, so that the roller 2 and the wheel hub 15 are relatively fixed in the circumferential direction, and the relative position of the roller 2 and the wheel hub 15 can be locked by tightening the fastening screw 21.
