Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically to a wear-resistant trolley case wheel. Background Technology

[0002] A rolling suitcase is a type of luggage with a pull rod and wheels. Because it can be dragged while walking, it greatly reduces the burden of carrying and is very convenient to use. Therefore, it is widely used in business trips, travel, and other scenarios. A rolling suitcase is mainly composed of a suitcase body, wheels, pull rod, locks, and other components.

[0003] Existing suitcase wheels lack sufficient rebound and shock absorption during use, resulting in impact on the contents. To overcome this deficiency, existing technology (Chinese patent application number 202323374521.7, application date 2023-12-12) describes a suitcase wheel with a shock-absorbing structure. By adding a shock-absorbing and rebounding device in the middle of the device, the suitcase, regardless of its weight, experiences a certain degree of rebound and shock absorption upon landing. Furthermore, by installing a forward shock-absorbing spring within the support assembly, the wheel provides a degree of cushioning during forward, backward, and braking movements, preventing excessive inertia on the contents. However, existing suitcase wheels still suffer from insufficient wear resistance during actual use, leading to frequent damage and air leaks requiring replacement, thus making them inconvenient to use.

[0004] To address the aforementioned issues, innovative design based on existing equipment is urgently needed. Therefore, we have proposed a wear-resistant suitcase wheel that can effectively solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant suitcase wheel to solve the problem mentioned in the background art that the existing suitcase wheels still have insufficient wear resistance during actual operation, which leads to the wheels being easily damaged and leaking air, requiring replacement and making them inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant suitcase wheel, comprising a mounting bracket, and a wheel body rotatably mounted on the inner side of the mounting bracket via a wheel axle; the tread of the wheel body is provided with uniformly distributed V-shaped grooves, and the tread surface is also uniformly formed with irregularly shaped debris patterns, with the V-shaped grooves and debris patterns spaced apart; the wheel axle is mounted on the inner side of the mounting bracket via a buffer mounting assembly, the buffer mounting assembly comprising two sets of wear-resistant clamping blocks uniformly clamping the outer side of the wheel axle, a movable rod fixedly connected to the outer wall of the wear-resistant clamping blocks, and the movable rod slidably connected to the inner side of the mounting bracket, and a buffer spring fixedly connected between the end of the movable rod and the inner wall of the mounting bracket; a cleaning brush is mounted on the top inner side of the mounting bracket via a mounting seat, and the bottom end of the cleaning brush contacts the wheel body, used to clean away gravel adhering to the surface of the wheel body, thereby providing a protective function.

[0007] Preferably, the tread pattern is made by attaching rubber shavings, which are made from recycled waste tires, to the surface of the wheel body, which can provide better grip.

[0008] Preferably, the tire side of the wheel body has evenly distributed side grooves, and the side grooves and V-shaped grooves are distributed alternately.

[0009] Preferably, the top inner wall of the mounting bracket is fixedly connected to a mounting block with a T-shaped structure, and the top of the mounting seat is provided with a matching T-shaped groove, and the mounting seat slides on the outside of the mounting block through the T-shaped groove.

[0010] Preferably, the rear end of the mounting block is fixedly connected to a sealing plate, and the front end of the mounting block is provided with a limiting component for limiting the mounting seat.

[0011] Preferably, the limiting component includes two limiting blocks that are snapped into the interior of both sides of the mounting base. A connecting rod is fixedly connected to the outer wall of the limiting block, and one side of the connecting rod extends through to the outside of the mounting bracket and is fixedly connected to a pull-out block. A mounting spring is also fixedly connected between the two limiting blocks and the inner walls of both sides of the mounting bracket.

[0012] Preferably, each of the two limiting blocks is fixedly installed with an attractive magnetic block on the side that is close to each other, so that the two blocks generate an attractive force.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the wear-resistant trolley wheel, through the intermittent cooperation of V-groove and chip pattern, can effectively improve the yield stress of the wheel body, thereby improving its wear resistance and extending its service life; by setting the buffer installation component, the wear-resistant clamping block is adaptively clamped on the outside of the wheel axle to prevent the trolley from being squeezed and worn by the wheel body when it is impacted, which further improves the wear protection of the wheel body; by setting the cleaning brush, the gravel adhering to the surface of the wheel body can be cleaned to play a protective role. The specific contents are as follows: (1) by opening the V-groove on the tire surface of the wheel body, the yield stress of the wheel body can be effectively improved. At the same time, with the intermittent cooperation of chip pattern, the wear resistance of the wheel body itself can be effectively improved, thereby extending its service life.

[0014] (2) By setting up a buffer mounting component, the elastic extension and contraction of the buffer spring and the limited sliding of the moving rod inside the mounting bracket are used to make the wear-resistant clamping block adaptably clamped on the outside of the wheel axle. This allows the force between the wheel axle and the mounting bracket to be effectively buffered and dissipated when the trolley case is subjected to external impact, thereby preventing the wheel body from being squeezed and worn, which further improves the wear protection of the wheel body.

[0015] (3) Install the cleaning brush through the mounting bracket. When the wheel body rolls, the cleaning brush will come into contact with the wheel body and rub against it, which can clean away the stone particles adhering to the wheel body, so as to prevent the stone particles from being worn and punctured when they roll on the surface of the wheel body, so as to facilitate use.

[0016] (4) By setting a limiting component, the two limiting blocks are pushed by the installation spring and stably inserted into the inner side of the mounting base, which can effectively ensure the limiting effect on one end of the mounting base. With the cooperation of the sealing plate, the two ends of the mounting base and the mounting block can be laterally limited, so as to further improve the installation stability of the mounting base and the cleaning brush.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a wear-resistant suitcase wheel, including a mounting bracket 1, and a wheel body 3 is rotatably mounted on the inner side of the mounting bracket 1 via a wheel axle 2; the tread of the wheel body 3 is provided with uniformly distributed V-shaped grooves 4, and the tread surface is also uniformly formed with irregularly shaped chip patterns 5, and the V-shaped grooves 4 and chip patterns 5 are distributed alternately. By opening the V-shaped grooves 4, the yield stress of the wheel body 3 can be effectively improved. At the same time, with the interval cooperation of the chip patterns 5, the wear resistance of the wheel body 3 itself can be effectively improved, thereby extending its service life. The chip patterns 5 are made by pasting rubber chips made from recycled waste tires onto the surface of the wheel body 3. It can provide good grip, especially in wet conditions such as rainy days, and can better maintain the friction between the wheel body 3 and the ground to ensure the smooth movement of the suitcase.

[0026] In addition, the tire sidewall of the wheel body 3 is provided with evenly distributed side grooves 6, and the side grooves 6 and V-shaped grooves 4 are distributed alternately to improve the wear resistance and anti-slip effect of the tire sidewall of the wheel body 3.

[0027] Meanwhile, the axle 2 is installed inside the mounting bracket 1 via a buffer mounting assembly. The buffer mounting assembly includes two sets of wear-resistant clamping blocks 7 that are evenly clamped on the outside of the axle 2. A movable rod 8 is fixedly connected to the outer wall of the wear-resistant clamping block 7, and the movable rod 8 is slidably connected to the inside of the mounting bracket 1. A buffer spring 9 is fixedly connected between the end of the movable rod 8 and the inner wall of the mounting bracket 1. Through the elastic extension and contraction of the buffer spring 9 and the limited sliding of the movable rod 8 inside the mounting bracket 1, the wear-resistant clamping block 7 can be adaptively clamped on the outside of the axle 2. This allows the force between the axle 2 and the mounting bracket 1 to be effectively buffered and dissipated when the suitcase is subjected to external impact, thereby preventing the impact force from being transmitted to the wheel body 3 and causing it to be squeezed and worn. This further enhances the wear protection of the wheel body 3.

[0028] Example 2: Based on Example 1, a cleaning brush 11 is installed on the inner top of the mounting bracket 1 via the mounting base 10, and the bottom end of the cleaning brush 11 contacts the wheel body 3 to clean away the gravel adhering to the surface of the wheel body 3, so as to play a protective role. When the wheel body 3 rolls, the cleaning brush 11 will contact and rub against the wheel body 3, which can clean away the gravel particles adhering to the wheel body 3, so as to prevent the gravel from being worn and punctured when it rolls on the surface of the wheel body 3, so as to facilitate use.

[0029] Furthermore, a T-shaped mounting block 12 is fixedly connected to the inner wall of the top of the mounting bracket 1, and a matching T-shaped groove is provided at the top of the mounting seat 10. The mounting seat 10 slides on the outside of the mounting block 12 through the T-shaped groove. This achieves the longitudinal stability of the mounting seat 10 on the mounting bracket 1, so that the sweeping brush 11 is always in contact with the wheel body 3 to ensure its sweeping effect.

[0030] Furthermore, the rear end of the mounting block 12 is fixedly connected to the sealing plate 13, and the front end of the mounting block 12 is provided with a limiting component to limit the mounting base 10. Through the cooperation of the sealing plate 13 and the limiting component, the two ends of the mounting base 10 and the mounting block 12 can be laterally limited, so as to further improve the installation stability of the mounting base 10 and the cleaning brush 11.

[0031] Specifically, the limiting component includes two limiting blocks 14 that are snapped into the interior of both sides of the mounting base 10. A connecting rod 15 is fixedly connected to the outer wall of the limiting block 14, and one side of the connecting rod 15 extends through to the outside of the mounting bracket 1 and is fixedly connected to a pull-out block 16. A mounting spring 17 is also fixedly connected between the two limiting blocks 14 and the inner walls of both sides of the mounting bracket 1. By setting the limiting component, the mounting spring 17 pushes the two limiting blocks 14 to stably insert them into the inner side of the mounting base 10, which can effectively ensure the limiting effect on one end of the mounting base 10. When the mounting base 10 and the cleaning brush 11 need to be disassembled and replaced, it is only necessary to move the two pull-out blocks 16 outward. The limiting blocks 14 are moved outward synchronously through the connection of the connecting rod 15 until the two limiting blocks 14 are dislodged from the mounting base 10. At this time, the mounting base 10 is moved along the mounting block 12 to the front end, which can realize the convenient disassembly of the mounting base 10 and the cleaning brush 11.

[0032] In addition, magnetic blocks 18 are fixedly installed on the side of the two limit blocks 14 that are close to each other. The attraction force of the two magnetic blocks 18 ensures the stability of the two limit blocks 14 inserted into the inner side of the mounting base 10 even when the suitcase is moving and bumpy.
