Description

Technical Field

[0001] The utility model relates to the technical field of trolley case parts, in particular to a self-limiting telescopic trolley case universal wheel. Background Art

[0002] A trolley case is a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because of the trolley on the case. The tube of the trolley is also divided into square tubes and round tubes, which are convenient for dragging while walking, greatly reducing the burden. Trolley cases can be carried by hand or dragged. The wheels of the trolley cases we usually use are basically located at the bottom of the case, but modern people have designed a new form of trolley case, which is designed into a cylindrical shape, and the wheels are completely wrapped outside the case. This roller design allows this trolley case to better adapt to different terrains, such as directly pulling the case to go up and down stairs easily. In 2012, the main materials used were cloth boxes, ABS hard boxes, leather boxes, PC, etc., and the usability was divided into three categories: fixed wheels, universal wheels, and the latest detachable universal wheel trolley boxes. The trolleys must be built-in, and the material must be steel (external trolleys and wheels are definitely not able to adapt to the rough loading and unloading of various flights nowadays)! The box body must have a steel frame, the fabric should preferably be rainproof, and the material with a larger particle size is better because it is more wear-resistant. Needless to say, the wheels must be built-in (by the way, many boxes are said to be equipped with four wheels for steering, and checked boxes must not use such wheels because they are exposed too much outside and are easy to fall off). The material of the wheels is of course rubber, and the smaller the sound when pulled on the ground, the better. The zipper is also very important, but it is not necessarily the bigger the better. It still depends on the material and the feel of trying it out.

[0003] The application number is CN201921797990.0, which discloses a universal wheel of a trolley case, including a linking buckle plate, a buffer pad plate is provided at the bottom of the linking buckle plate, the buffer pad plate is fixedly connected to the linking buckle plate, a first linkage shaft rod is provided at the lower left side of the bottom of the buffer pad plate, a second linkage shaft rod is provided on the right side of the first linkage shaft rod, the second linkage shaft rod is fixedly connected to the buffer pad plate, the bottoms of the first linkage shaft rod and the second linkage shaft rod are embedded in the interior of the bearing column tube, the bottom of the bearing column tube is provided with a reinforcement seat plate, the bearing column tube is fixedly connected to the reinforcement seat plate, the bottom of the reinforcement seat plate is rotatably connected to a rotating seat plate, and the bottom of the rotating seat plate is connected to a stainless steel cover frame. This kind of equipment is easy to control and has high stability, and is worthy of promotion.

[0004] Although the above utility model uses a linking buckle plate, a buffer pad is provided at the bottom of the linking buckle plate, and the buffer pad is fixedly connected to the linking buckle plate, etc., which makes the device easy to control and has high stability and is worthy of promotion, it has a disadvantage that when the device is in use, the movement mode of its moving wheels is relatively unstable, which poses certain hidden dangers.

[0005] Therefore, it is necessary to replace the original moving wheel with the current adjustable moving wheel assembly, so that when using this device, after moving to the specified position, it can not only be braked by its braking method, but also have a supporting effect, which can further avoid the movement after the fixed moving roller. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 As shown, the utility model is a self-limiting telescopic trolley case universal wheel, comprising an adjustable moving wheel assembly 1, a telescopic rod assembly 2 is installed on the top of the adjustable moving wheel assembly 1, and an adjustment assembly 3 is installed inside the top of the telescopic rod assembly 2.

[0027] By setting up the adjustable moving wheel assembly 1, when using the device, after moving to the specified position, the assembly can not only brake by means of the brake, but also provide support, thus further avoiding the movement after the fixed moving roller.

[0028] The adjustable moving wheel assembly 1 includes a mounting frame 101, a moving roller 102 is installed inside the mounting frame 101, an adjusting rod 103 is installed on the front side of the moving roller 102, and a brake assembly 105 is installed on the top of the rear side, and a support rod 104 is installed on the bottom of the adjusting rod 103. The moving roller 102 moves forward, and after reaching the specified position, the brake assembly 105 on the rear side is braked, and the adjusting rod 103 is rotated downward at the same time, so that the height of the support rod 104 at the bottom is higher than that of the moving roller 102, the fixed limiting effect can be achieved.

[0029] The telescopic rod assembly 2 includes a telescopic outer rod 201 , a telescopic inner rod 202 is installed inside the telescopic outer rod 201 , slide rails 203 are installed on both sides of the telescopic inner rod 202 , and a limit plate 204 is installed on the top thereof.

[0030] The adjusting component 3 includes an air pump 301, a push rod 302 is installed at the bottom of the air pump 301, a mounting block 303 is installed at the bottom of the push rod 302, and they are fixedly connected by a connecting rod 304. The air pump 301 in the internal adjusting component 3 pushes the push rod 302 at the bottom to achieve the effect of pushing the telescopic inner rod 202 out of the telescopic outer rod 201, thereby achieving the effect of lengthening.

[0031] The brake assembly 105 includes a mounting page 1051, a rotating rod 1052 is installed at the bottom of the mounting page 1051, the rotating rod 1052 is connected to a rotating page 1053, and a brake pad 1054 is installed at the end of the rotating page 1053. By stepping on the brake pad 1054, the rotating page 1053 and the rotating rod 1052 installed on the top of the brake pad 1054 can be rotated and the brake pad 1054 can be pressed onto the moving roller 102 to achieve braking.

[0032] The telescopic outer rod 201 includes a rod body 2011 , and a limiting sliding groove plate 2012 is installed at the inner bottom of the rod body 2011 .

[0033] When using this device, the telescopic rod assembly 2 drives the adjusting moving wheel assembly 1 and the adjusting assembly 3 to be installed around the suitcase body. Later, when in use, when it is necessary to move, first move forward through the moving roller 102, and after reaching the specified position, brake the brake assembly 105 on the rear side. When braking, it is only necessary to step on the brake pad 1054. The rotating page 1053 and the rotating rod 1052 installed on the top of the brake pad 1054 can be used to rotate and press the brake pad 1054 on the moving roller 102 to achieve braking. At the same time, the adjusting rod 103 on the front side of the moving roller 102 is turned downward. When the height of the support rod 104 at the bottom is higher than the moving roller 102, the fixed limit effect can be achieved. When in use, when encountering a rough road, the telescopic rod assembly 2 will be used for lifting and lowering, and the rod body can be raised to avoid friction damage to the box body. When it is adjusted, the air pump 301 in the internal adjustment assembly 3 pushes the push rod 302 at the bottom to achieve the effect of pushing the telescopic inner rod 202 out of the telescopic outer rod 201, thereby achieving the effect of stretching. In the process of telescoping, the sliding rail and the limiting slide groove plate 2012 are adapted to make the stretching smoother and more stable, and avoid shaking.
