Technical Field
[0001] This utility model belongs to the field of omnidirectional wheel technology, specifically, it relates to an omnidirectional wheel that can be fixed. Background Technology
[0002] Existing display cases use casters to provide direction of movement and rotation. When the display case is moved to a designated position, the base screws are manually tightened to ensure a tight contact between the bottom and the ground, thus securing the display case. However, with these existing base screws, the contact with the ground is often too tight, making it impossible to tighten the screws when moving the case. In this case, the case needs to be manually pushed backward to tilt it slightly before the base screws can be tightened. If the display case is full of items, it becomes impossible to move the case at all, causing significant inconvenience when moving the display case. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a fixed omnidirectional wheel. Through the cooperation of the fixing component, magnetic block, magnetic rod, and locking component, the omnidirectional wheel can be switched freely between fixed and running modes. This solves the problem that adjusting the base screws is time-consuming and laborious when moving objects such as display cabinets and refrigerators carried by the omnidirectional wheel after it is fixed by the base screws.
[0004] The present invention adopts the following technical solution.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, and not all embodiments. Based on the spirit of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] like Figure 1-7 As shown, this utility model provides a fixed omnidirectional wheel, including a mounting plate 1, a rotating shaft 2, a bracket 3, a swivel wheel 6, and a fixing assembly. The mounting plate 1, rotating shaft 2, bracket 3, and swivel wheel 6 are installed sequentially from top to bottom. The mounting plate 1 has four bolt holes, and the mounting plate 1 is installed onto objects such as display cabinets and refrigerators by bolts. The mounting plate 1 is fixedly connected to the top end of the rotating shaft 2, and the bottom end of the rotating shaft 2 is rotatably connected to the top end of the bracket 3. In some embodiments, the rotating shaft 2 and the bracket 3 are connected by a bearing, with the inner ring of the bearing connected to the rotating shaft 2 and the outer ring connected to the bracket 3, allowing the rotating shaft 2 to rotate easily relative to the bracket 3, thereby driving the swivel wheel 6 to achieve omnidirectional steering.
[0028] The bracket 3 is welded together from the bracket horizontal plate 4 and two bracket side plates 5. The rotating wheel 6 is mounted on the two bracket side plates 5 through the wheel axle. The wheel axle is equipped with nuts or snap rings at both ends to fix the rotating wheel 6 and prevent it from moving axially.
[0029] The fixing component includes a fixing member 7, a magnetic block 10, a magnetic rod 11, and a locking component. The magnetic block 10 is fixedly connected to the bottom end of the bracket horizontal plate 4. In some embodiments, the magnetic block 10 is glued to the bracket horizontal plate 4 or fixed by non-magnetic screws.
[0030] The locking components include a locking top plate 12, a first locking side plate 13, a second locking side plate 14, and a third locking side plate 15. The first locking side plate 13, the second locking side plate 14, and the third locking side plate 15 are fixedly connected to the bottom of the locking top plate 12. The second locking side plate 14 and the third locking side plate 15 are perpendicular to the first locking side plate 13, and the locking top plate 12 is integrally formed with the first locking side plate 13, the second locking side plate 14, and the third locking side plate 15. One end of the magnetic rod 11 is fixedly connected to the first locking side plate 13. The magnetic block 10 has a groove 16, the diameter of which is compatible with the diameter of the magnetic rod 11. The other end of the magnetic rod 11 can be inserted into the groove 16 of the magnetic block 10. The fixing component 7 consists of an integrally formed fixing horizontal plate 8 and a fixing inclined plate 9, with an obtuse angle between the fixing horizontal plate 8 and the fixing inclined plate 9. The top of the fixed horizontal plate 8 is fixedly connected to the support horizontal plate 4. The fixed horizontal plate 8 has a sliding groove 17 with a T-shaped cross-section, and the sliding groove 17 is adapted to the outer contour of the locking top plate 12. The fixed horizontal plate 8 and the locking top plate 12 are engaged. The fixed inclined plate 9 has a through hole with a diameter adapted to the diameter of the magnetic rod 11. One end of the magnetic rod 11 can pass through the through hole on the fixed inclined plate 9. The magnetic block 10 and the magnetic rod 11 are made of strong magnetic material. One end of the magnetic rod 11 passes through the through hole and is inserted into the groove 16 of the magnetic block 10. The magnetic block 10 and the magnetic rod 11 are tightly attracted together by magnetic force. At the same time, the fixing member 7 provides support and guidance for the locking component.
[0031] The second locking side plate 14 and the third locking side plate 15 are provided with protrusions 18 and friction strips 19. The protrusions 18 are provided with anti-slip strips 20. The friction strips 19 are fixedly connected to the bottom ends of the second locking plate 14 and the third locking plate 15, and are inclined inwards. When the magnetic rod 11 is inserted into the groove 16 of the magnetic block 10, the friction strips 19 adhere to the outer wall of the rotating wheel 6, using friction to fix the rotating wheel 6 and prevent it from rotating, thereby achieving the fixation of the universal wheel. In a preferred but non-limiting embodiment, the bottom of the second locking side plate 14 and the third locking side plate 15 is arc-shaped, and the center of this arc is the same as the center of the rotating wheel 6. The friction strips 19 are perpendicular to the second locking side plate 14 and the third locking side plate 15. When the magnetic rod 11 is inserted into the groove 16 of the magnetic block 10, the friction strips 19 are tightly adhered to the outer wall of the rotating wheel 6.
[0032] The fastener 7 and locking components are made of non-magnetic materials, while the magnetic block 10 and magnetic rod 11 are made of strong magnetic materials such as neodymium iron boron magnets.
[0033] This utility model also provides a method for using a fixable caster wheel. When the caster wheel needs to be fixed, the operator pinches the protrusions 18 on the second locking side plate 14 and the third locking side plate 15, inserts one end of the magnetic rod 11 through the through hole on the fixing inclined plate 9 and into the groove 16 of the magnetic block 10, and the magnetic block 10 and the magnetic rod 11 are attracted together by magnetic force. At the same time, the locking top plate 12 moves along the sliding groove 17 in the fixing horizontal plate 8 and engages with the fixing horizontal plate 8; the friction strip 19 contacts the rotating wheel 6 to generate friction, thereby fixing the caster wheel. When it is necessary to move objects such as display cabinets or refrigerators, simply pull the magnetic rod 11 out of the groove 16 of the magnetic block 10 to release the fixation of the rotating wheel 6 and restore the caster wheel's rotation function.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
