Abstract
Description
Technical Field
[0001] This utility model relates to the field of caster wheel technology, specifically an anti-tangling caster wheel. Background Technology
[0002] A swivel caster is a type of caster that is mounted on a caster wheel bracket and can rotate 360 degrees horizontally under dynamic or static loads. During use, swivel casters are prone to getting tangled in threads, short fabrics, etc., which affects their operation and makes them inconvenient to clean, thus impacting their performance.
[0003] A search revealed that patent application CN222157095U discloses an anti-winding caster wheel, including a shaft frame and a wheel body, which are mounted on the shaft frame and can rotate on the shaft frame. It also includes two dustproof end caps, which are respectively located at both ends of the wheel body. The dustproof end caps are provided with mounting grooves, and the bottom wall of the mounting groove protrudes from the end face of the wheel body. A drop path is formed between the end face of the wheel body and the dustproof end caps. A shaft frame and a bolt assembly are connected between the two mounting grooves, which are arranged through the shaft frame and the two mounting grooves. This can improve the anti-winding performance of the caster wheel and meet the requirements of high efficiency and low maintenance in industrial transportation.
[0004] However, due to the dustproof end caps and axle brackets, hair and thread tend to get tangled between the wheel and axle brackets when the wheels are in use, causing the wheels to jam. The anti-tangling effect is poor. At the same time, because the universal wheels have strong sliding and rotation performance, they are prone to movement when the device needs to be placed stably. The universal wheels lack locking devices, resulting in poor performance.
[0005] Therefore, we propose an anti-tangling universal wheel. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an anti-tangling universal wheel, which solves the problems of poor anti-tangling effect and poor performance of existing devices.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-winding universal wheel, including a mounting plate, wherein a fixing plate of suitable specifications is assembled on the bottom surface of the mounting plate, and a U-shaped axle is fixedly installed on the bottom surface of the fixing plate;
[0008] The axle frame is equipped with a wheel axle that is positioned opposite to and passes through the axle frame. A wheel of the same specification and located inside the axle frame is rotatably connected to the outer wall of the wheel axle. Grooves of the same specification are opened on the front and rear sides of the wheel. A bearing A of the same specification is equipped at the center of the wheel. A shaft hole of the same specification and passing through is opened on the front side of the bearing A. Protective covers of the same specification are equipped on the front and rear sides of the wheel. Through holes of the same specification are opened on the outer wall of the protective covers. Two sets of limiting sleeves of the same specification are fixedly installed on the outer wall of the wheel axle. The front and rear sides of the limiting sleeves are in contact with the inner side of the axle frame and the outer side of the wheel, respectively. Evenly distributed blades are fixedly installed on the outer wall of the limiting sleeves.
[0009] A nut of the appropriate specification is threaded onto the outer wall of the front side of the axle. A rotary switch rotatably connected to the outer wall of the axle is fixedly installed on the rear side of the nut. A limiting cover plate of the appropriate specification is fixedly installed on the rear side of the rotary switch. The limiting cover plate is L-shaped and is positioned opposite to the wheel. A friction strip with the opposite position is installed on the bottom surface of the limiting cover plate.
[0010] Preferably, the top surface of the mounting plate has four sets of mounting holes in opposite positions, which facilitates the installation of the casters.
[0011] Preferably, the mounting plate has a pivot hole at the center of its top surface, a bearing B is installed in the pivot hole, a pivot of the same specification is installed in the pivot B, and the pivot is connected to the fixing plate, so that the wheel can be driven to rotate 360 degrees through the pivot.
[0012] Preferably, a limiting groove is provided on the front side of the shaft frame, and a limiting block with a corresponding position is fixedly installed on the rear side of the limiting cover plate. The limiting block can rotate within the limiting groove, which can limit the limiting cover plate to a certain extent and ensure its stability.
[0013] Preferably, the bearing A has slots on both the front and rear sides, and the inner side of the protective cover is fixedly installed with a matching locking block, which facilitates the installation and removal of the protective cover.
[0014] Preferably, a limiting ring located in front of the nut is fitted on the outer wall of the axle, which can limit the nut.
[0015] 1. This anti-tangling caster wheel, through the setting of a protective cover, a limiting sleeve and a blade, the protective cover can prevent objects such as thread from getting tangled inside the wheel, and when hair and yarn get tangled on the limiting sleeve, the blade can cut the hair and thread, ensuring the stability of the wheel rotation and providing a good anti-tangling effect.
[0016] 2. Simultaneously, through the setting of the nut, rotary switch and limit cover, the nut rotates on the wheel axle through the thread, which drives the rotary switch to rotate. The rotary switch drives the limit cover to rotate, and the limit cover contacts the outer wall of the wheel, thereby limiting and fixing the wheel, ensuring the stability of the device and improving its use effect.
