Description

Technical Field

[0001] This utility model belongs to the field of caster technology, and particularly relates to an ultra-heavy-duty waterproof and dustproof caster. Background Technology

[0002] Casters are a general term encompassing swivel casters, fixed casters, and swivel casters with brakes. Swivel casters, also known as universal wheels, allow 360-degree rotation. Fixed casters, also called directional casters, lack a rotating mechanism and cannot turn. These two types of casters are typically used together; for example, a handcart has two directional wheels at the front and two swivel wheels near the push handle at the rear. Casters are made from various materials, such as PP, PVC, PU, ​​cast iron, nylon, TPR, iron-core nylon, and iron-core PU. Existing outdoor foot-operated brake casters typically brake by the foot pressing against the wheel surface, which is cumbersome and prone to scratching and wear over time, affecting performance. Therefore, heavy-duty waterproof and dustproof casters have been developed.

[0003] For example, Chinese patent CN205432870U discloses a fixable furniture caster, including a caster, a caster bracket, an end face bearing, a mounting plate, a fixing bracket, a locking bolt, a fixing plate, and a friction pad. The caster is rotatably connected to the caster bracket, and the upper end of the caster bracket is rotatably connected to the mounting plate through the end face bearing. The fixing bracket is disposed on one side of the caster bracket, the locking bolt is disposed on the fixing bracket, the locking bolt is rotatably connected to the fixing plate, and the friction pad is disposed on the fixing plate.

[0004] This patent has the following problems:

[0005] Existing technologies present limitations in their application, making it inconvenient for tires to withstand high loads. Uneven movement occurs when the tires bear heavy loads, and slippage occurs when water splashes, reducing tire stability. Furthermore, existing technologies do not provide adequate dust protection for outdoor use, and foreign objects can easily clog the tires during movement, compromising safety. Therefore, we propose an ultra-heavy-duty waterproof and dustproof wheel. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing an ultra-heavy-dustproof and waterproof wheel, thereby improving tire stability and ensuring tire safety.

[0007] In view of this, the present invention provides an ultra-heavy-duty waterproof and dustproof wheel, including a gasket cylinder, and further comprising: a wheel bearing fixedly installed inside the gasket cylinder; a wheel dust cover fixedly installed outside the gasket cylinder; a wheel sealing ring four fixedly installed inside the wheel dust cover; wheel sealing ring five fixedly installed on both sides of the wheel sealing ring four; wheel spokes installed around the outside of the wheel dust cover; an outer tire fixedly installed outside the wheel spokes; a positioning wheel arm movably installed outside the gasket cylinder; a positioning bar column penetrating inside the positioning wheel arm; and a positioning nut threaded onto the outside of the positioning bar column.

[0008] Based on the above structure, the gasket cylinder is fixedly installed inside and outside the wheel bearing fixing end. Then, the wheel bearing drives the gasket cylinder to rotate. The wheel spokes then provide stable support for the outer tire. The outer tire then allows the moving wheel to move stably, enabling the tire to bear heavy pressure and thus improving the stability of tire movement. Then, the positioning bar passes through the rotating end inside the wheel bearing to support the tire's rotation. The positioning wheel arm then protects the tire. Finally, the positioning nut secures the positioning bar inside the positioning wheel arm, protecting the tire during movement and thus improving the safety of tire use.

[0009] Preferably, a fixed wheel arm is fixedly installed on one side of the positioning wheel arm, and the fixed wheel arm is made of metal.

[0010] Preferably, each of the fixed wheel arms has a fixed post installed through it, and each fixed post has a fixed nut threaded on its outside. One end of each fixed nut has a fixed fastening washer threaded on it. A fixed top sleeve is fixedly installed on the top of the fixed wheel arm, and a brake wheel arm is fixedly installed on one side of the fixed wheel arm.

[0011] Preferably, a brake pedal is movably mounted on the bottom of the brake wheel arm, a brake positioning plate is movably mounted on the bottom of the brake pedal, and a waterproof cover is fixedly mounted on the bottom of the brake positioning plate.

[0012] Preferably, a rotary bearing is fixedly installed on the top of the fixed top sleeve, a sealing ring one is fixedly installed on the outside of the rotary bearing, a sealing ring two is fixedly installed on the outside of the sealing ring one, a sealing ring three is fixedly installed on the outside of the sealing ring two, and a mounting base plate is fixedly installed on the top of the rotating end inside the rotary bearing.

[0013] Preferably, a mounting top plate is fixedly mounted on the top of the mounting base plate, and the mounting top plate is made of metal.

[0014] Preferably, the mounting top plate has a through mounting positioning inner hole, and mounting positioning side holes are provided on both sides of the mounting positioning inner hole.

[0015] The beneficial effects of this utility model are:

[0016] 1. This heavy-duty waterproof and dustproof wheel is fixedly installed through the inside of the gasket cylinder and the outside of the wheel bearing fixing end. Then, the wheel bearing drives the gasket cylinder to rotate, and the wheel spokes provide stable support for the outer tire. The outer tire then enables the moving wheel to move stably. The wheel dust cover provides waterproof protection for the wheel bearing, and wheel seal rings four and five are used for waterproof sealing. This allows the tire to withstand heavy pressure and water splashes. The tire will not move or bump when carrying heavy objects, thus improving the stability of the tire movement.

[0017] 2. This heavy-duty waterproof and dustproof wheel supports the tire's rotation by having a positioning bar pass through the rotating end inside the wheel bearing. Then, the positioning wheel arm protects the tire, and the positioning nut secures the positioning bar inside the positioning wheel arm. This design protects the tire during movement and prevents foreign objects from clogging it, thus improving the safety of tire use. Attached Figure Description
