Description

Technical Field

[0001] The utility model relates to the technical field of Mecanum wheels, in particular to a Mecanum wheel. Background Art

[0002] The Mecanum wheel is a patent of the Swedish Mecanum company. This omnidirectional motion is based on the principle of a central wheel with many axles located around the wheel. These angled axles convert part of the wheel steering force into a wheel normal force.

[0003] A Chinese patent application CN219583853U discloses a Mecanum wheel, and the key points of its technical solution are: multiple hexagonal bolts are provided to cooperate with locking nuts to facilitate users to disassemble and assemble the rolling body, and to facilitate users to clean and perform daily maintenance on the rolling body; multiple first connecting screw holes, second connecting screw holes, and third connecting screw holes are provided to install the Mecanum wheel with the installation object, so that the Mecanum wheel can be flexibly installed according to installation needs, while increasing the applicability of the Mecanum wheel; and the connection screw holes are installed in a bolt-to-installation manner, which also facilitates users to disassemble the Mecanum wheel as a whole, and also facilitates users to clean or perform daily maintenance on the Mecanum wheel, thereby ensuring the service life of the Mecanum wheel.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when a Mecanum wheel is needed, most Mecanum wheels are installed on a vehicle driving component through a bearing when in use. Since most bearings are fixed by bolts and other workpieces, and a considerable number of Mecanum wheels are small in size, it is inconvenient to operate when disassembling and assembling the bearings. Therefore, a Mecanum wheel is proposed to address the above-mentioned problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: a Mecanum wheel described in the utility model comprises a wheel body and a fixing device, a plurality of rollers are fixedly connected to the surface of the wheel body, and a bearing is inserted into the inner wall of the wheel body; fixing devices are provided on both sides of the wheel body, and the fixing devices comprise two support columns, the side walls of the two support columns are fixedly connected to the side walls of the wheel body, a swivel is rotatably connected to the surface of the support column, and an insert block is fixedly connected to the side wall of the swivel, a slot is provided on the surface of the bearing near the insert block, the insert block is inserted into the inner wall of the slot of the bearing, the swivel drives the insert block to move, and the insert block is inserted into the inner wall of the slot, and the position of the bearing can be fixed by arranging the support column, the swivel and the insert block.

[0007] Preferably, a handle is fixedly connected to one end of the swivel surface away from the plug block. When the swivel needs to be moved, the handle is pulled to allow the handle to drive the swivel to move. The setting of the handle can facilitate the movement of the swivel.

[0008] Preferably, a strong magnetic block is fixedly connected to the surface of the wheel body near the two swivels, and a strong magnet is fixedly connected to the surface of the swivel near the strong magnetic block. The side walls of the strong magnet and the side walls of the strong magnetic block are magnetically attracted to each other, the strong magnet will fit the strong magnetic block, and the strong magnetic block will attract the strong magnet. By setting the strong magnetic block and the strong magnet, the angle of the swivel can be limited.

[0009] Preferably, hooks are fixedly connected to the surfaces of the two swivels, and elastic bands are covered on the surfaces of the two hooks. After the two swivels are rotated to a suitable angle, the elastic bands are covered on the surfaces of the two hooks. The setting of the elastic bands and the hooks assists in limiting the angle of the swivels.

[0010] Preferably, protective devices are provided on both sides of the wheel body, and the protective devices include shields, which are located on the side walls of the wheel body and are sleeved on the surface of the bearing. A plurality of blocks are fixedly connected to the surface of the shield, and a slot is provided on the surface of the wheel body near the block. The block is inserted into the inner wall of the slot, and the shield is sleeved on the surface of the bearing. By providing the shield, the bearing can be protected and the possibility of dust entering the bearing when the wheel body is not in use can be reduced.

[0011] Preferably, a plurality of anti-sliding blocks are fixedly connected to the surface of the block, and the anti-sliding blocks are inserted into the inner wall of the slot of the wheel body. A drawstring is fixedly connected to the side wall of the shield. When the shield needs to be moved, the drawstring is pulled to drive the shield to move. By setting the drawstring, the shield can be moved conveniently.

[0012] The utility model is beneficial in that:

[0013] 1. When the bearing needs to be installed and fixed, the utility model inserts the bearing into the inner wall of the wheel body, and then pushes the handle to drive the swivel to rotate. The swivel rotates on the surface of the support column, and the swivel drives the plug block and the strong magnet to move. The plug block is inserted into the inner wall of the slot of the bearing, and the strong magnet will fit the strong magnetic block. The strong magnetic block and the strong magnet will be attracted together. After the swivel is fixed, the elastic band is stretched to let the elastic band be sleeved on the surface of the hook. By arranging the support column, the swivel and the plug block, the bearing can be fixed, and at the same time, the need for tools in the traditional bolt fixing method is reduced, thereby facilitating the disassembly and assembly of the bearing.

[0014] 2. When the wheel body is not needed, the utility model aligns the shield with the wheel body, pushes the shield to drive the blocking block to slide, drives the anti-sliding block to slide, and inserts the blocking block and the anti-sliding block into the inner wall of the slot. When the bearing needs to be used, pulls the drawstring to drive the shield to move, and the shield is removed from the surface of the wheel body. By setting the shield, the bearing can be protected and the possibility of dust entering the bearing can be reduced. The blocking block and the anti-sliding block can fix the position of the shield.
