Abstract
Description
Technical Field
[0001] This utility model relates to the field of caster technology, and in particular to an anti-winding caster. Background Technology
[0002] In fields such as industrial production, medical care, and home life, casters are key components for enabling equipment movement, and their operational stability directly affects the efficiency and lifespan of the equipment.
[0003] Currently, existing casters mainly consist of rollers, brackets, axles, and mounting plates. Due to the gap between the two sides of the rollers and the inner wall of the bracket, hair, ropes, and other debris on the ground can get caught in the gap as the caster rotates. This entanglement increases the rotational resistance of the caster, causing the axle to jam or stop, severely affecting the mobility of the equipment. To address this issue, we propose an anti-entanglement caster. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5An anti-tangle caster includes a mounting plate 1. Two sets of brackets 2 are fixedly connected to the bottom of the mounting plate 1, and rollers 3 are rotatably connected to the inner sides of the two sets of brackets 2. Pre-drilled slots are provided at the four corners of the mounting plate 1, allowing workers to easily fix the mounting plate 1 to the bottom of the equipment. The connection method between the brackets 2 and the rollers 3, as well as the rotation principle of the rollers 3, are existing technologies and will not be elaborated upon here. Protective covers 4 are symmetrically distributed on the front and rear sides of the brackets 2, and two sets of protective plates 5 are fixedly connected to the top of the protective covers 4. The protective plates 5 are designed with an L-shaped structure. The gap between the bottom of the protective cover 4 and the rollers 3 is small, which can block debris without affecting the normal rolling of the rollers 3. During the installation of the two sets of protective covers 4, the side walls of the two sets of protective covers 4 abut against each other, effectively preventing debris from entering the gap between the rollers 3 and the mounting plate 1, thereby further protecting the rollers 3.
[0023] Furthermore, refer to Figure 2 , Figure 4 and Figure 5 It can be seen that a fixing block 6 is fixedly connected to the side of the bracket 2, and a slot 7 is opened inside the fixing block 6. A connecting rod 8 is inserted into the fixing block 6, and a first moving block 9 is fixedly connected to the inner side of the connecting rod 8. The side of the first moving block 9 is connected to the inner wall of the slot 7 through a first spring 10. A second connecting block 11 is distributed on the side of the first moving block 9, and a slider 12 is fixedly connected to the side of the second connecting block 11. The end of the slider 12 is connected to the inner wall of the slot 7 through a second spring 13. The interior of the protective plate 5 has a mating joint that matches the second connecting block 11. In use, the spring force coefficient of the first spring 10 is greater than that of the second spring 13. Therefore, the first moving block 9 will push the second connecting block 11 into the docking groove in the default state. When the operator pulls the connecting rod 8 laterally, the first moving block 9 will no longer abut against the second connecting block 11. This will cause the second connecting block 11 to move laterally by the spring force of the second spring 13, from being directly embedded into the inside of the slot 7, and being pulled out from the docking groove inside the protective plate 5. This will release the restriction on the protective plate 5, so that the operator can remove the protective cover 4 from the side of the bracket 2.
[0024] Furthermore, refer to Figure 5 It can be seen that there are two sets of second connecting blocks 11 and sliders 12, and the two sets of second connecting blocks 11 and sliders 12 are symmetrically distributed about the central axis of the fixing block 6. Through the cooperation of the two sets of second connecting blocks 11, sliders 12 and the second spring 13, the tightness of the protective plate 5 when it is installed on the side of the bracket 2 can be effectively improved.
[0025] Furthermore, refer to Figure 4 and Figure 5It can be seen that the end of the connecting rod 8 is fixedly connected to the connecting strip 14, and the connecting strip 14 is set as a columnar structure. During use, the columnar structure of the connecting strip 14 makes it easy for the staff to quickly pull the connecting rod 8, thereby effectively improving the convenience of using the device.
[0026] Furthermore, refer to Figure 1 and Figure 5 It can be seen that the side of the bracket 2 is fixedly connected with a positioning post 15, and the inside of the protective plate 5 is provided with a positioning groove that matches the positioning post 15. Through the cooperation between the positioning post 15 and the positioning groove, the reliability of the protective plate 5 when it is installed on the side of the bracket 2 can be further guaranteed.
[0027] Furthermore, refer to Figure 1 It can be seen that the edge of the protective cover 4 is fixedly glued with a protective ring 16, and the cross section of the protective ring 16 is set as an L-shaped structure. Since the protective ring 16 is made of rubber and covers the edge of the protective cover 4, the edge of the protective cover 4 can be protected to prevent the protective cover 4 from being easily damaged by external forces, and the service life of the protective cover 4 can be effectively guaranteed.
[0028] Working principle: When using this utility model, the operator can first install the mounting plate 1 on the bottom of the corresponding equipment to meet the moving needs of the equipment. During the rolling of the roller 3, the two sets of protective covers 4 set on the side of the mounting plate 1 and the two sets of protective plates 5 distributed on the top of the protective covers 4 can prevent debris from entering the gap between the bracket 2 and the roller 3, so as to effectively ensure the safety of the roller 3 during operation.
[0029] When maintenance work such as lubrication of roller 3 is required, the operator can pull the connecting bar 14 horizontally, which will drive the connecting rod 8 and the first moving block 9 to move simultaneously. At this time, the two sets of second connecting blocks 11 can be reset by the elastic force of the second spring 13 and move closer to each other, and be pulled out from the docking groove opened inside the protective plate 5. Thus, the operator can pull the protective cover 4 horizontally, which can be quickly removed from the side of the bracket 2 so that the operator can maintain roller 3. The above is the complete working principle of this utility model.
[0030] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
