Description

Technical Field

[0001] The utility model relates to the technical field of trolley case wheels, in particular to a trolley case wheel capable of being lubricated with oil. Background Art

[0002] The wheels of a suitcase, also known as universal wheels or casters, are an important part of a travel suitcase. They are usually composed of multiple rollers and circular wheels. The roller plates are parallel to the rollers within a plane, and the structure allows 360-degree horizontal rotation, allowing the suitcase to move in any direction. The size of the wheel is also a factor that affects mobility. Generally speaking, the larger the wheel diameter, the smoother the movement.

[0003] The wheel seat can install the roller at the bottom of the trolley case to facilitate the rolling of the roller, so as to drive the trolley case to move. As the trolley case is used for a longer time, the damage degree of the roller surface gradually increases. The damage of the roller makes the rolling on the road not smooth enough. The wheel seat and the roller are often installed in one piece. The wheel seat and the roller can only be replaced at the same time, and the damaged roller cannot be replaced separately, which increases the cost of the trolley case wheel and is not easy to use. The roller is provided with a bearing inside, which makes it inconvenient to lubricate the bearing inside the trolley case wheel, resulting in greater friction between the bearing and the roller, further shortening the service life of the roller. For this reason, a trolley case wheel that can be lubricated with oil is designed. Utility Model Content

[0004] The purpose of the utility model is to provide a suitcase wheel that can be lubricated with oil, so as to solve the problem proposed in the above-mentioned background technology that a damaged roller cannot be replaced individually, which increases the cost of the suitcase wheel, and is not easy to use, and bearings are arranged inside the roller, which makes it inconvenient to lubricate the bearings inside the suitcase wheel.

[0006] As a preferred technical solution of the utility model, one side of the two extension plates is fixedly connected to one side of the first clamping ring and the second clamping ring respectively, and one end of the two springs is fixedly connected to both sides of the top of the second positioning plate respectively.

[0007] As a preferred technical solution of the utility model, the other ends of the two springs are fixedly connected to the bottom ends of the two extension plates respectively.

[0008] As a preferred technical solution of the utility model, an auxiliary shaft is inserted and connected to one side of the second positioning plate, and the first clamping ring is sleeved on one end of the auxiliary shaft.

[0009] As a preferred technical solution of the utility model, the top end of the positioning steel wheel is fixedly connected to the bottom end of the first positioning plate, and the anti-pressure ring is fixedly sleeved on one end of the lower column.

[0010] As a preferred technical solution of the utility model, the diameter of the anti-pressure ring is larger than the diameter of the lower column.

Two clamping rings 12, an extension plate 10 is provided on one side of the first clamping ring 11 and the second clamping ring 12, and two springs 9 are provided on the top of the second positioning plate 8. After being subjected to a large force, the spring 9 will deform slightly, driving the first clamping ring 11 to move, and can quickly limit the positioning steel wheel 5 between the first clamping ring 11 and the second clamping ring 12. After the spring 9 stops being subjected to force and the roller 2 rolls normally, the positioning steel wheel 5 will always remain stably in the middle position between the first clamping ring 11 and the second clamping ring 12 without moving.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, an auxiliary shaft 14 is inserted and connected on one side of the second positioning plate 8, and the first clamping ring 11 is sleeved on one end of the auxiliary shaft 14. The top end of the positioning steel wheel 5 is fixedly connected to the bottom end of the first positioning plate 4, and the anti-pressure ring 7 is fixedly sleeved on one end of the lower column 6. The utility model is a trolley case wheel that can be oiled and lubricated. By arranging the anti-pressure ring 7, the lower column 6, the oil filling plug 13 and the auxiliary shaft 14, the first clamping ring 11 can move at one end of the auxiliary shaft 14, the spring 9 is made of stainless steel material and has a certain hardness. When no force is applied, the spring 9 will always remain motionless, and the first clamping ring 11 and the second clamping ring 12 are supported by the spring 9. The two springs 9 can always keep the first clamping ring 11 and the second clamping ring 12 stable.

[0026] Working principle: The wheels of a suitcase, also known as universal wheels and casters, are important components of a travel suitcase. They are usually composed of multiple rollers and circumferential wheels. The roller plate and the roller are parallel in a plane, and the structure allows 360-degree horizontal rotation, so that the suitcase can be moved in any direction. The size of the wheel is also a factor that affects the mobility. Generally speaking, the larger the wheel diameter, the smoother the movement. The suitcase wheel seat 1 can install the roller 2 at the bottom of the suitcase to facilitate the rolling of the roller 2 to drive the suitcase to move. As the suitcase is used for a longer time, the degree of damage to the surface of the roller 2 gradually increases. The damage to the roller 2 is caused by the road surface. The rolling is not smooth enough, and the box wheel seat 1 and the roller 2 are often installed in an integrated manner. The box wheel seat 1 and the roller 2 can only be replaced at the same time, and the damaged roller 2 cannot be replaced alone, which increases the cost of the trolley case wheel and is not easy to use. The roller 2 is provided with a bearing inside, which is not convenient for lubrication of the bearing inside the trolley case wheel, resulting in greater friction between the bearing and the roller 2, further shortening the service life of the roller 2. At this time, the bottom of the first clamping ring 11 and the second clamping ring 12 are supported by the spring 9 and the second positioning plate 8 respectively, and the extension plate 10, the first clamping ring 11 and the second clamping ring 12 are all made of steel materials with greater hardness. The spring 9 is slightly deformed after being subjected to a large force, driving the first clamping ring 11 to move, and the positioning steel wheel 5 can be quickly limited between the first clamping ring 11 and the second clamping ring 12. After the spring 9 stops being subjected to force and the roller 2 rolls normally, the positioning steel wheel 5 will always be stably maintained in the middle position between the first clamping ring 11 and the second clamping ring 12, and the top of the box wheel seat 1 can be installed with the bottom of the trolley case through the limit bolt, and the buckle between the positioning steel wheel 5 and the second positioning plate 8 is convenient for repairing the damaged roller 2. The replacement improves the usability of the trolley case wheel. The first clamping ring 11 can move at one end of the auxiliary shaft 14. The spring 9 is made of stainless steel and has a certain hardness. When no force is applied, the spring 9 will always remain motionless. The first clamping ring 11 and the second clamping ring 12 are supported by the spring 9. The two springs 9 can always keep the first clamping ring 11 and the second clamping ring 12 stable. The oil filling plug 13 is rotated in the opposite direction. After the oil filling plug 13 is taken out from the top of the lower column 6, the lubricating oil can be injected into the interior of the roller 2. The lubricating oil can reduce the friction of the components arranged inside the roller 2, and mainly has the effect of lubrication and cooling, thereby extending the service life of the trolley case wheel.
