Abstract
Description
Technical Field
[0001] This utility model relates to the field of balance wheel technology, specifically a balance wheel that can smoothly transition through locally concave ground. Background Technology
[0002] Balance casters, also known as stationary casters, can only move in a straight line. They are mechanical components installed on the bottom of equipment, primarily used to assist in movement and maintain stability. Balance casters are commonly found in industrial equipment, material handling tools, medical equipment, robots, and some household appliances. Their core function is to achieve flexible movement of equipment through their wheeled structure, while careful optimization ensures stability and good maneuverability during movement.
[0003] Existing balancing wheels, designed to distribute axial pressure from above, often employ a double-row design. However, when these balancing wheels traverse surfaces with localized depressions, vibrations are transmitted to the upper equipment. During rapid equipment movement, these vibrations become not only more frequent but also more intense. This vibration can potentially loosen internal components, affecting operational stability, and may also accelerate component wear, shorten equipment lifespan, and cause damage. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a balance wheel that can smoothly transition through locally concave ground, making the balance wheel less prone to vibration during movement.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a balance wheel that can smoothly transition through locally concave ground, comprising a mounting plate, slots on both sides of the lower end of the mounting plate, a positioning groove matching the slots at the lower end of the mounting plate, a threaded rod slidably connected inside the slots, a positioning plate matching the positioning groove fixedly connected to the end of the threaded rod near the mounting plate, a wheel body rotating with the threaded rod, a connecting plate on the side of the wheel body away from the mounting plate, and a mounting nut threadedly connected to the end of the threaded rod away from the mounting plate through the connecting plate.
[0006] Furthermore, both sides of the upper end of the mounting plate are fixedly connected with lead screws, and a through groove matching the lead screws is opened in the middle of the upper end of the connecting plate. A fixing nut is threaded to the end of the lead screw away from the mounting plate.
[0007] Furthermore, the through groove is annular.
[0008] Furthermore, an extrusion plate is provided between the mounting plate and the connecting plate, and the end of the extrusion plate near the mounting plate has a chamfer.
[0009] Furthermore, both ends of the inner side of the extrusion plate are fixedly connected with limit rods, both sides of the upper end of the connecting plate are provided with limit grooves, both sides of the upper end of the mounting plate are provided with fixing grooves that match the limit grooves, and the end of the limit rod passes through the limit groove and abuts against the end of the fixing groove.
[0010] Furthermore, both sides of the wheel body are provided with washers, which are sleeved on the outside of the threaded rod and are slidably connected to the threaded rod.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This type of balancing wheel, which can smoothly transition through locally concave ground, has two wheels that are staggered during movement. Therefore, when the balancing wheel crosses a concave area, one wheel will be in contact with the concave ground while the other wheel remains on the ground. This effectively reduces the vibration generated when the balancing wheel crosses a concave ground, thereby mitigating the adverse effects of vibration on the upper equipment.

[0018] 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.
[0019] Please see Figure 1-4A balance wheel that can smoothly transition through locally concave ground includes a mounting plate 1. Slots 2 are provided on both sides of the lower end of the mounting plate 1. A positioning groove 3 matching the slots 2 is provided at the lower end of the mounting plate 1. A threaded rod 4 is slidably connected inside the slots 2. A positioning plate 5 matching the positioning groove 3 is fixedly connected to the end of the threaded rod 4 near the mounting plate 1. A wheel body 6 that rotates with the threaded rod 4 is sleeved on the threaded rod 4. A connecting plate 7 is provided on the side of the wheel body 6 away from the mounting plate 1. The end of the threaded rod 4 away from the mounting plate 1 passes through the connecting plate 7 and is threadedly connected to a mounting nut 8.
[0020] The balancing wheel of this invention, which can smoothly transition through locally concave ground, has two staggered wheel bodies 6 during movement. Therefore, when the balancing wheel crosses the concave position of the ground 17, one wheel body 6 will contact the concave ground 17 while the other wheel body 6 will remain on the ground 17. This effectively reduces the vibration generated when the balancing wheel crosses the concave ground 17, thereby mitigating the adverse effects of vibration on the upper equipment. At the same time, the distance between the two threaded rods 4 can be increased according to the equipment installation space, and this distance is equal to the size of the concave ground 17 for smooth transition.
[0021] like Figure 2 and Figure 3 As shown, both sides of the upper end of the mounting plate 1 are fixed with screw rods 9, and the middle position of the upper end of the connecting plate 7 is provided with a through groove 10 that matches the screw rods 9. The end of the screw rod 9 away from the mounting plate 1 is threaded with a fixing nut 11.
[0022] Specifically, when installing the wheel body 6, simply put the wheel body 6 onto the threaded rod 4, then align the through groove 10 at the upper end of the connecting plate 7 with the lead screw 9, then move the connecting plate 7 towards the mounting plate 1. After the wheel body 6 and the connecting plate 7 have moved to the appropriate positions, tighten the mounting nut 8 and the fixing nut 11 respectively.
[0023] like Figure 2 As shown, the through groove 10 is annular. The annular through groove 10 makes it easier for the lead screw 9 to be inserted into the through groove 10.
[0024] like Figure 2 and Figure 4 As shown, an extrusion plate 12 is provided between the mounting plate 1 and the connecting plate 7, and the end of the extrusion plate 12 near the mounting plate 1 has a chamfer.
[0025] like Figure 2 , Figure 3 and Figure 4 As shown, both ends of the inner side of the extrusion plate 12 are fixed with limit rods 13, and both sides of the upper end of the connecting plate 7 are provided with limit grooves 14. Both sides of the upper end of the mounting plate 1 are provided with fixing grooves 15 that match the limit grooves 14. The end of the limit rod 13 passes through the limit groove 14 and abuts against the end of the fixing groove 15.
[0026] Specifically, before tightening the fixing nut 11, the chamfered end of the extrusion plate 12 can be inserted between the mounting plate 1 and the connecting plate 7. At the same time, the limiting rod 13 will also be inserted into the limiting groove 14 until the limiting rod 13 abuts against the fixing groove 15. Finally, the fixing nut 11 is tightened to reinforce the connecting plate 7 and make the connection between the connecting plate 7 and the mounting plate 1 more stable.
[0027] like Figure 2 As shown, both sides of the wheel body 6 are provided with a washer 16, which is sleeved on the outside of the threaded rod 4 and is slidably connected to the threaded rod 4.
[0028] Specifically, the gasket 16 serves a protective function, preventing friction between the wheel 6 and the mounting plate 1 or connecting plate 7 when the wheel rotates, thus avoiding damage to the mounting plate 1 or connecting plate 7.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
