Description

Technical Field

[0001] The utility model relates to the technical field of trolley case accessories, in particular to an oil-filled trolley case wheel. Background Art

[0002] A trolley case is a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because the case has a trolley. The tube of the trolley is also divided into square tubes and round tubes, which makes it easier to drag while walking and greatly reduces the burden.

[0003] Currently, most of the wheels of trolley cases are directly fixed to the bearings. During long-term use, the lubricating oil on the bearings is consumed, causing them to get stuck and become unsmooth, making it difficult for people to pull the wheels manually. When the wheels need to be oiled, the bearings need to be removed, which is a cumbersome operation and takes a lot of time. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil-filled trolley case wheel comprises a mounting frame, a bearing is rotatably connected inside the mounting frame, an adjusting wheel is fixedly connected to the outer surface of the bearing, a protrusion is fixedly connected to the outer surface of the adjusting wheel, the mounting frame is fixedly connected to a guide tube at the position of the adjusting wheel, a top rod is slidably arranged inside the guide tube, an adjusting box is fixedly connected to the top of the mounting frame, a storage box is slidably connected to the inside of the adjusting box, a material guide tube is fixedly connected to the bottom end of the storage box, the bottom end of the material guide tube passes through the top of the mounting frame and is movably connected to the inside of the guide tube, a sealing cover is movably connected to the bottom end of the material guide tube, the top end of the sealing cover is fixedly connected to a connecting column, two positioning frames are fixedly connected to the inside of the storage box, the insides of the two positioning frames are slidably connected to the outer surface of the connecting column, and wheel hubs are fixedly connected to both ends of the bearing.

[0006] As a further preferred embodiment of the present technical solution, adjustment through holes are provided on both sides of the adjustment box, two fixing grooves are provided on both side walls of the two adjustment through holes, adjustment blocks are fixedly connected on both sides of the storage box, adjustment grooves are provided on both sides of the two adjustment blocks, pressure springs are fixedly connected inside the four adjustment grooves, the other ends of the four pressure springs are fixedly connected to fixed blocks, outer surfaces of the four fixed blocks are movably plugged into the four adjustment grooves respectively, and the four fixed blocks are respectively plugged into the four fixed grooves located at the same position.

[0007] As a further preferred embodiment of the technical solution, two grooves are provided on the outer surface of the bearing, and a No. 1 clamping ring is clamped inside the two grooves.

[0008] As a further preferred embodiment of the technical solution, two positioning rings are fixedly connected inside the guide tube, the interiors of the two positioning rings are slidably connected to the outer surface of the push rod, and a No. 2 clamping ring is clamped on the outer surface of the push rod.

[0011] The utility model provides an oil-filled suitcase wheel, which has the following beneficial effects:

[0012] (1) The utility model drives the adjusting wheel to rotate by the rotation of the bearing. The convex block on the adjusting wheel pushes the push rod to move upward in the guide tube and pushes open the sealing cover in the guide tube. The lubricating oil in the storage box enters the interior of the bearing through the guide tube and the guide tube under the action of gravity, thereby realizing automatic oil filling of the bearing. In addition, the indirect oil filling can make the interior of the bearing quickly lubricated, and the oil filling is convenient, thereby improving the oil filling efficiency.

[0013] (2) The utility model pushes the two adjusting blocks to slide in the adjusting through holes, so that the fixed block slides inside the adjusting groove under the action of the squeezing of the fixing groove, and the pressing spring undergoes elastic deformation. When the fixed block enters the next fixing groove, the return spring restores the elastic deformation to push the fixed block out of the adjusting groove and into the fixing groove, thereby fixing the storage box and causing the storage box to fall off the guide tube, thereby ending the oil filling. The utility model has a stable fixation and a simple structure, and the oil filling can be controlled at any time. BRIEF DESCRIPTION OF THE DRAWINGS

Two positioning frames 15 are fixedly connected to the inside of the storage box 9. The insides of the two positioning frames 15 are slidably connected to the outer surfaces of the connecting column 14. The two ends of the bearing 2 are fixedly connected to the hub 5. By setting the protrusion 4, the push rod 11 can be controlled to move indirectly. By setting the push rod 11, the sealing cover 13 can be lifted up, so that the lubricating oil in the storage box 9 can enter the guide tube 10. By setting the adjusting box 8, the storage box 9 can be positioned. By setting the positioning frame 15, the connecting column 14 can be positioned to prevent it from being skewed.

[0021] like Figure 1-4 As shown, adjustment through holes 21 are opened on both sides of the adjustment box 8, and two fixing grooves 22 are opened on both side walls of the two adjustment through holes 21. Adjustment blocks 17 are fixedly connected on both sides of the storage box 9, and adjustment grooves 18 are opened on both sides of the two adjustment blocks 17. The four adjustment grooves 18 are fixedly connected with pressure springs 19, and the other ends of the four pressure springs 19 are fixedly connected with fixed blocks 20. The outer surfaces of the four fixed blocks 20 are movably plugged into the four adjustment grooves 18 respectively, and the four fixed blocks 20 are respectively plugged into the four fixed grooves 22 located at the same position. The pressure springs 19 are provided to reset the fixed blocks 20, and the storage box 9 can be positioned and fixed by providing the fixing grooves 22.

[0022] like Figure 2 and Figure 3 As shown, two grooves 6 are provided on the outer surface of the bearing 2, and a No. 1 clamping ring 7 is clamped inside the two grooves 6 to position the bearing 2 and prevent it from shaking greatly.

[0025] like Figure 1-3 As shown, a fixing seat 23 is fixedly connected to the top of the adjustment box 8 for fixing to the suitcase.

[0026] The utility model provides a trolley case wheel that can be filled with oil, and the specific working principle is as follows:

[0027] When it is necessary to fill the wheels of the trolley case with oil, the user pushes the two adjustment blocks 17 downward to make the storage box 9 slide downward and finally dock the guide tube 12 with the guide tube 10. During the docking process, the fixing block 20 slides inside the adjustment groove 18 under the action of the squeezing of the fixing groove 22, and the pressing spring 19 undergoes elastic deformation. After the fixing block 20 enters the next fixing groove 22, the return spring 16 restores the elastic deformation to push the fixing block 20 out of the adjustment groove 18 and into the fixing groove 22 to fix the storage box 9. Then the user pulls the trolley case to move forward. When the trolley case is moved, the wheel hub 5 rotates to drive the bearing 2 to rotate, and the bearing 2 rotates to drive the adjusting wheel 3 to rotate. The protrusion 4 on the adjusting wheel 3 pushes the push rod 11 to move upward in the guide tube 10 and pushes open the sealing cover 13 in the guide tube 12. The lubricating oil in the storage box 9 enters the bearing 2 through the guide tube 12 and the guide tube 10 under the action of gravity, and the bearing 2 is indirectly and automatically oiled. When the user feels that pulling the trolley case is easier, the two adjusting blocks 17 are pushed to make the guide tube 12 on the storage box 9 separate from the guide tube 10 and fix it.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
