Description

Technical Field

[0001] This utility model relates to the field of handcart tire technology, specifically a handcart tire with an internal skeleton. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving, so they must have high load-bearing capacity, traction capacity, and cushioning capacity.

[0003] According to a public notice (Announcement No.: CN217835269U) regarding a solid handcart tire with a layered skeleton structure, the use of the skeleton mechanism in the above application can improve the modification of the inherent shape of both sides of the tire, and use honeycomb and curvature for support, thereby improving the mechanical strength and shock absorption performance of the solid tire and ensuring stability during use.

[0004] However, in actual use, although the above-mentioned equipment has a double U-shaped structure inside the tire skeleton for pressure bearing and support, and the hollow state reduces the weight of the tire skeleton, the hollow double U-shaped structure arranged in a circular array can easily affect each other when the tire is squeezed. Over time, this can easily affect the strength and stability of the handcart tire itself. In view of this, we propose a handcart tire with an internal skeleton. Utility Model Content

[0005] The purpose of this invention is to provide a handcart tire with an internal skeleton to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a handcart tire with an internal skeleton, including a hub, a tire body detachably mounted on the outer side of the hub, an arc-shaped cavity formed on the arc-shaped outer surface of the hub, a partition fixedly mounted on the arc-shaped inner surface of the arc-shaped cavity, and a pressure-bearing cylinder fixedly mounted on the arc-shaped inner surface of the hub. Two sets of pressure-bearing cylinders are provided. One set of pressure-bearing cylinders has an annular partition fixedly connected to one side of the arc-shaped inner surface away from the hub. An mounting ring is fixedly connected to the axis of the annular partition via another set of pressure-bearing cylinders. A through-belt is passed through and fixedly connected to the arc-shaped inner wall of the pressure-bearing cylinder near its end. A spacer block is fixedly mounted on the outer surface of the through-belt. A curved belt is passed through and fixedly mounted at the center of the pressure-bearing cylinder.

[0007] Preferably, the number of partitions is set in multiple sets, and the multiple sets of partitions are evenly distributed in a circumferential array on the inner surface of the arc-shaped cavity. Furthermore, an arc-shaped groove is provided at the center of each partition, so that when the tire body is fitted on the outside of the arc-shaped cavity, the horizontal compressive strength of the wheel hub is guaranteed without excessively dividing the space inside the arc-shaped cavity.

[0008] Preferably, each group of pressure-bearing cylinders is provided with several cylinders, and the several pressure-bearing cylinders are evenly distributed in a circumferential array, so that the pressure from all directions inside the wheel hub can be buffered.

[0009] Preferably, the number of the through strips is set to two sets, and the two sets of through strips are mirror-distributed at both ends of the vertical central axis of the pressure cylinder, so that the several pressure cylinders arranged in a circular array can maintain a circular distribution state. The number of the spacers is set to multiple sets, and the spacers are set in the gap between two adjacent sets of pressure cylinders, thereby ensuring the ability of the pressure cylinder to resist the deformation pressure caused by external pressure on the hub.

[0010] Preferably, the curved strip is arranged in a wavy, circular pattern, and the curved strip passes through several pressure-bearing cylinders in a circular pattern to enhance the ability of the several pressure-bearing cylinders arranged in a circular pattern to resist lateral displacement.

[0011] Preferably, a single pressure-bearing cylinder in one of the two sets of pressure-bearing cylinders is positioned in the gap between two pressure-bearing cylinders in the other set, thereby enabling the two sets of pressure-bearing cylinders to cooperate with each other to enhance the pressure-bearing and deformation-resistant capabilities inside the hub.

[0012] Compared with the prior art, this utility model provides a handcart tire with an internal skeleton, which has the following beneficial effects:

[0013] 1. This handcart tire with an internal skeleton features two sets of interlocking pressure-bearing cylinders inside the hub. These cylinders, along with a through-belt and a curved belt, maintain a circular distribution. The spacers between adjacent cylinders and the wavy curved belt further enhance the cylinders' resistance to lateral displacement. This ensures stability when the hub is connected to the external drive shaft via the mounting ring, preventing deformation and damage to the hub under significant external pressure, thus protecting the handcart tire's safety and lifespan.

[0014] 2. The handcart tire with an internal skeleton has several partitions evenly distributed in a circular array inside the arc-shaped cavity. With the arc-shaped grooves opened inside the partitions, when the tire body is fitted on the outside of the arc-shaped cavity, the arc-shaped cavity forms a sealed cavity. The partitions are connected to the inner walls of the left and right sides of the arc-shaped cavity, which ensures the compressive strength of the wheel hub in the horizontal direction without excessively dividing the space inside the arc-shaped cavity, thereby ensuring the strength of the wheel hub.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a handcart tire with an internal skeleton, including a hub 1, a tire body 11 detachably mounted on the outer side of the hub 1, an arc-shaped cavity 2 opened on the arc-shaped outer surface of the hub 1, a partition 3 fixedly mounted on the arc-shaped inner surface of the arc-shaped cavity 2, a pressure-bearing cylinder 4 fixedly mounted on the arc-shaped inner surface of the hub 1, and two sets of pressure-bearing cylinders 4. One set of pressure-bearing cylinders 4 is fixedly connected to an annular partition 8 on one side of the arc-shaped inner surface away from the hub 1, and an installation ring 9 is fixedly connected to the axis of the annular partition 8 through the other set of pressure-bearing cylinders 4. A through-belt 5 is passed through and fixedly connected to the arc-shaped inner wall of the pressure-bearing cylinder 4 near the end, a spacer block 6 is fixedly mounted on the outer surface of the through-belt 5, and a curved belt 7 is passed through and fixedly mounted at the center of the pressure-bearing cylinder 4.

[0021] In one embodiment of this utility model, anti-slip textures are provided on the arc-shaped outer wall of the tire body 11 to ensure the static friction coefficient of the tire body 11 when in contact with the ground, thereby ensuring the grip of the tire body 11. In addition, multiple sets of partitions 3 are provided, and the multiple sets of partitions 3 are evenly distributed in a circumferential array on the arc-shaped inner surface of the arc-shaped cavity 2. An arc-shaped groove is provided at the center of the partition 3, so that when the tire body 11 is fitted on the outside of the arc-shaped cavity 2, the arc-shaped cavity 2 forms a sealed cavity. The partitions 3 are connected to the inner walls of the left and right sides of the arc-shaped cavity 2, ensuring the compressive strength of the wheel hub 1 in the horizontal direction without excessively dividing the space inside the arc-shaped cavity 2, thereby ensuring the strength of the wheel hub 1.

[0022] In addition, a cylindrical cavity is provided at the center of the hub 1 to facilitate the installation of the pressure-bearing cylinder 4, the annular partition 8, and the mounting ring 9. Each set of pressure-bearing cylinders 4 consists of several cylinders, which are evenly distributed in a circumferential array. This allows the pressure from all directions inside the hub 1 to be buffered, preventing damage to the mounting ring 9 and the transmission shaft mounted on the mounting ring 9 when the external pressure is too high, thus affecting the safety of the handcart tire. Furthermore, two sets of through-belts 5 are provided, which are mirror-distributed at both ends of the vertical central axis of the pressure-bearing cylinders 4, so that the several pressure-bearing cylinders 4 arranged in a circumferential array can maintain a circular distribution. Specifically, multiple sets of spacers 6 are provided, and the spacers 6 are located in the gaps between two adjacent sets of pressure-bearing cylinders 4, thereby ensuring the ability of the pressure-bearing cylinders 4 to resist the deformation pressure caused by external pressure on the hub 1.

[0023] In the embodiments of this utility model, the curved belt 7 is arranged in a wave-shaped circular ring, and the curved belt 7 passes through several pressure-bearing cylinders 4 in a circular array in a circular shape, so as to improve the ability of the several pressure-bearing cylinders 4 arranged in a circular array to resist lateral displacement, so as to ensure the stability of the wheel hub 1 when connected to the external drive shaft through the mounting ring 9, thereby avoiding deformation and damage of the wheel hub 1 when subjected to large external pressure, thereby reducing the safety and service life of the handcart tire.

[0024] Specifically, when the two sets of pressure-bearing cylinders 4 arranged in a circular array inside the hub 1 are installed, a single pressure-bearing cylinder 4 in the two sets of pressure-bearing cylinders 4 is placed in the gap between two pressure-bearing cylinders 4 in the other set, so that the two sets of pressure-bearing cylinders 4 cooperate with each other to improve the pressure-bearing and deformation resistance of the hub 1.

[0025] In this invention, during use, two sets of interlocking pressure-bearing cylinders 4 are arranged inside the hub 1. These, along with the through-belt 5 and curved belt 7 within the pressure-bearing cylinders 4, ensure that the several pressure-bearing cylinders 4 arranged in a circular array maintain a ring-shaped distribution. Furthermore, the spacer 6 between adjacent pressure-bearing cylinders 4 and the annular wavy curved belt 7 enhance the ability of the circularly arranged pressure-bearing cylinders 4 to resist lateral displacement. This ensures the stability of the hub 1 when connected to the external drive shaft via the mounting ring 9, thereby preventing deformation and damage to the hub 1 under significant external pressure, thus reducing the safety and lifespan of the handcart tire.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
