Description

Technical Field

[0001] This utility model relates to the field of caster wheels, specifically a caster wheel with automatic adjustment. Background Technology

[0002] In various devices and apparatuses that require movement and height adjustment, casters play a crucial role as a common support and movement component. They not only need to provide stable support but also possess flexible mobility and convenient height adjustment capabilities to meet the usage requirements in different scenarios.

[0003] In traditional fuma wheel adjustment structures, the adjusting gear seat is one of the key components. Users typically adjust it in two ways: one is by directly turning the adjusting gear seat by hand. While this method is convenient and requires no additional tools, it can easily cause abrasions to the skin on the hands during actual operation, and prolonged operation can lead to finger pain and discomfort, affecting the user experience and operational efficiency. While using a toothed wrench can turn the adjusting gear seat more effortlessly and precisely to achieve height adjustment, if a toothed wrench is not available, one can only revert to manual adjustment, again facing the problems of hand discomfort and inaccurate adjustment. Even if a toothed wrench is carried, when transferring it between different devices, there may be a situation where the wrench and the adjusting gear seat are incompatible, making it impossible to perform the adjustment operation normally. Summary of the Invention

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] A type of self-adjusting fuma wheel, such as Figure 1-4 As shown, the system includes a fuma wheel 1, which comprises a main frame 101. Two mounting holes 108 are formed on both sides of the main frame 101. A functional mechanism 2 is fitted onto the outer surface of the main frame 101. The functional mechanism 2 includes a mounting ring 201, with bolts 202 on both sides of the mounting ring 201, each bolt being screwed into one of the two mounting holes 108. An arc-shaped baffle 203 is provided on the outer surface of the mounting ring 201, and an adjusting groove 204 with an arc-shaped structure is provided at the bottom of the arc-shaped baffle 203. The main frame 101 of the fuma wheel 1 has mounting holes 108 and is fitted with the functional mechanism 2. Bolts 202 on both sides of the mounting ring 201 of the functional mechanism 2 are screwed into the mounting holes 108. This structure has many advantages. Firstly, the connection between the bolts 202 and the mounting holes 108 ensures a stable connection between the functional mechanism 2 and the main frame 101. During the use of the fuma wheel, the functional mechanism 2 will not easily loosen or fall off, ensuring the stability of the overall structure. On the other hand, this connection method is simple and reasonable, which facilitates the assembly and disassembly of the wheel, reduces production and maintenance costs, and provides a reliable foundation for the subsequent functional mechanism 2 to achieve other functions.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The arc-shaped baffle 203 is wedge-shaped and covers the adjustment groove 109. The adjustment tooth groove 204 and the adjustment tooth seat 106 are adapted to and mesh with each other. The wedge-shaped arc-shaped baffle 203 effectively prevents external mud, sand, and debris from entering the adjustment groove 109 during daily use, avoiding the accumulation of foreign objects from affecting the normal rotation of the adjustment tooth seat 106 and protecting the internal adjustment structure. The adaptive meshing design of the adjustment tooth groove 204 and the adjustment tooth seat 106 is ingenious. When the height of the caster wheel needs to be adjusted, the functional mechanism 2 can be removed and used as a toothed wrench to precisely rotate the adjustment tooth seat 106, realizing the multi-purpose function of the functional mechanism 2 and greatly improving the convenience of use.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4Functional mechanism 2 is made of engineering plastic, and its surface is coated with a waterproof layer. Engineering plastic possesses good strength and toughness, ensuring that functional mechanism 2 is not easily deformed or damaged when subjected to certain external forces, meeting the structural strength requirements of Foma wheel in various usage scenarios. Simultaneously, the waterproof coating effectively prevents moisture and humidity from corroding functional mechanism 2, avoiding problems such as rust and corrosion of the internal structure due to dampness, thereby extending the service life of functional mechanism 2. This not only reduces product maintenance costs but also enhances the overall reliability and stability of Foma wheel products, improving the user experience.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main frame 101 has an adjustment groove 109 in the middle of its outer surface. A bolt 202 is screwed into the adjustment groove 109. An adjustment gear seat 106 is located on the top of the bolt 202, and a top block 107 is rotatably connected to the bottom of the bolt 202 via a bearing. This ingenious design allows for easy adjustment of the caster height. Simply rotate the adjustment gear seat 106. Because the bolt 202 is screwed into the adjustment groove 109, the rotation of the adjustment gear seat 106 causes the bolt 202 to rotate, moving it up and down within the adjustment groove 109. The bearing connection ensures that the top block 107 moves stably with the bolt 202, achieving precise adjustment of the caster height. The entire structure is simple, reliable, and easy to operate, meeting the height adjustment needs of casters in various scenarios.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main frame 101 has a wheel frame 102 at its back, with wheels 103 mounted on its bottom. The wheel frame 102 provides a stable support structure for the wheels 103, firmly securing them to the main frame 101 and preventing them from wobbling or falling off during movement. Simultaneously, the well-designed wheel frame 102 ensures the wheels 103 can rotate normally, reducing friction and resistance during rotation, making movement smoother. This design enhances the overall performance of the wheel, demonstrating good stability and flexibility whether carrying heavy loads or moving on different surfaces.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main frame 101 has a bearing seat 104 on its top, and a mounting plate 105 is mounted on top of the bearing seat 104. The bearing seat 104 effectively reduces friction during rotation of the main frame 101, making the caster wheel more flexible and easy to adjust in angle or direction, reducing energy loss and improving efficiency. The mounting plate 105 provides a convenient interface for connecting the caster wheel to other equipment. Through the mounting plate 105, the caster wheel can be easily installed on various devices requiring mobile support, such as workbenches and machines, greatly expanding its application range. This design enhances the practicality of the caster wheel and meets the needs of different users in different scenarios.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main frame 101 is made of high-strength metal material with a rust-proof treatment. High-strength metal material has excellent load-bearing capacity, capable of withstanding significant weight and pressure, ensuring the caster wheel will not deform or be damaged when carrying heavy loads, thus guaranteeing its structural stability and safety. The rust-proof treatment effectively prevents the main frame 101 from rusting in harsh environments such as humidity and corrosion, avoiding problems such as reduced structural strength and shortened service life caused by rust. This treatment extends the service life of the main frame 101, allowing the caster wheel to maintain stable performance during long-term use and providing users with reliable operating assurance.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4The wheel 103 is made of wear-resistant rubber with an anti-slip texture to enhance friction with the ground. The wheel 103 is connected to the main frame 101 via a wheel frame 102. The wear-resistant rubber material has excellent wear resistance, capable of withstanding prolonged friction and wear, significantly extending the service life of the wheel 103 and reducing the frequency and cost of replacement. The anti-slip texture increases the friction between the wheel 103 and the ground, effectively preventing slippage during movement, especially on wet or uneven surfaces, ensuring safety and stability. The connection between the wheel frame 102 and the main frame 101 ensures coordinated operation between the wheel 103 and the main frame 101, improving the overall performance of the wheel.

[0033] The implementation principle of this embodiment is as follows: First, the main frame 101 of the fuma wheel 1 is made of high-strength metal material and the surface is treated with anti-rust to ensure the overall structure is sturdy, durable and corrosion resistant, providing a stable and reliable support frame for the entire fuma wheel. Mounting holes 108 are opened on both sides of the main frame 101, and a functional mechanism 2 is fitted on the upper surface of its outer surface. Bolts 202 are provided on both sides of the mounting ring 201 of the functional mechanism 2 and screwed into the mounting holes 108 to realize a stable connection between the functional mechanism 2 and the main frame 101. The arc-shaped baffle 203 has a wedge-shaped structure to block the adjustment groove 109. Under normal conditions, it can prevent debris from entering and protect the internal adjustment structure. When the height needs to be adjusted, the functional mechanism 2 is removed. The adjustment tooth groove 204 at the bottom of the arc-shaped baffle 203 is adapted to mesh with the tooth shape of the adjustment tooth seat 106. At this time, the functional mechanism 2 can be used as a toothed wrench. Rotating the adjustment tooth seat 106 will drive the top block 107 to move through the bolt 202 to achieve height adjustment. The main frame 101 has a wheel frame 102 on the back to mount wheels 103. The wheels 103 are made of wear-resistant rubber and have anti-slip texture to enhance friction with the ground and facilitate movement. The main frame 101 has a bearing seat 104 and a mounting plate 105 on the top to facilitate connection and installation with other equipment.
