Description

Technical Field

[0001] This utility model belongs to the field of roller can ear technology, specifically relating to a quick-release roller can ear rubber wheel replacement structure. Background Technology

[0002] Rubber wheels play a crucial role in various types of machinery used across numerous fields. Whether it's material handling trolleys on industrial production lines, small transport equipment on construction sites, or mobile shelving units in logistics warehouses, rubber wheels serve as key walking or transmission components. Because they operate continuously under various working conditions and often bear loads of varying weights, frequent use leads to widespread wear. With increased usage time and accumulated operations, the rubber layer on the wheel surface gradually thins, and the tread pattern wears down. This not only reduces the wheel's friction, affecting the equipment's stability and transmission accuracy, but may also cause abnormal vibrations and noise during operation.

[0003] Traditional methods of connecting rubber wheels to hubs present numerous inconveniences when disassembling them. For example, some older designs involve a large number of bolts and nuts of various sizes, requiring maintenance personnel to use a wide range of complex tools, such as socket wrenches, torque wrenches, and extension rods, to perform the disassembly. Furthermore, the entire disassembly process is extremely cumbersome, requiring not only the sequential loosening of each bolt but also careful handling to prevent the nuts from falling or being lost. More importantly, due to limited operating space and structural complexity, disassembly often requires experienced technicians with considerable skill and time, significantly increasing labor and time costs. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release roller can ear rubber wheel replacement structure, aiming to solve the problem in some older designs where the connection structure involves a large number of bolts and nuts of various specifications. This requires maintenance personnel to have a large number of complex tools, such as socket wrenches, torque wrenches, and extension rods of different sizes, to perform the disassembly operation. Moreover, the entire disassembly process is extremely cumbersome, requiring not only to loosen each bolt in sequence but also to carefully prevent the nuts from falling or being lost. More importantly, due to the limited operating space and the complexity of the structure, it often requires professional technicians with rich experience and skilled techniques to spend a considerable amount of time to complete the disassembly work, greatly consuming manpower and time costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release roller can ear rubber wheel replacement structure, including a base plate, a buffer cylinder installed on the surface of the base plate, the top of the buffer cylinder connected to one side of the mounting frame, a side plate rotatably installed inside the mounting frame, one side of the side plate contacting the outer wall of the hub, a rubber wheel sleeved on the outer wall of the hub, and a through hole opened in the transverse center of the hub;

[0006] The outer wall of the hub has two sets of mounting holes, each set of four mounting holes are equally spaced, and the bottom of each mounting hole is connected to a through hole.

[0007] Preferably, a screw is fixedly connected to one side of each of the side discs, and the screw is threaded inside the crossbar;

[0008] The crossbar is installed inside the through hole, and the length of the crossbar is the same as the transverse length of the through hole. The outer wall of the crossbar is in movable contact with one end of the movable rod, and the movable rod is movably inserted into the installation hole.

[0009] Preferably, the movable rod and the crossbar have a semi-circular notch at their joint end, and the length of the movable rod is greater than the longitudinal length of the mounting hole.

[0010] Preferably, the inner wall of the rubber wheel is provided with two sets of positioning holes, each set of positioning holes consists of four holes, and the four positioning holes of each set are equally spaced on the inner wall of the rubber wheel. The end of the movable rod away from the crossbar is inserted into the positioning hole, and each movable rod has a matching positioning hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When it is necessary to remove and replace an excessively worn rubber wheel, first remove the side plate from the mounting bracket, then fix the rubber wheel in place, and then rotate one side plate. The rotation of the side plate will drive the screw, allowing the rotated side plate to disengage from the crossbar. Next, pull the other side plate; the pulling force on this side plate will further pull the crossbar out of the hub. At this point, place the hub horizontally and adjust it by slightly tilting it. This will allow the movable rod to disengage from the positioning hole, releasing the relative fixing structure between the rubber wheel and the hub. The rubber wheel can then be removed from the hub, making the removal and disassembly of the rubber wheel much easier during use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides the following technical solution: a quick-release roller can ear rubber wheel replacement structure, including a base plate 1, a buffer cylinder 2 installed on the surface of the base plate 1, the top of the buffer cylinder 2 connected to one side of the mounting frame 3, a side plate 4 rotatably installed inside the mounting frame 3, one side of the side plate 4 contacting the outer wall of the wheel hub 5, a rubber wheel 6 sleeved on the outer wall of the wheel hub 5, and a through hole 51 opened in the transverse center of the wheel hub 5;

[0022] Two sets of mounting holes 52 are provided on the outer wall of the hub 5. Each set of mounting holes 52 has four holes at equal intervals, and the bottom of each mounting hole 52 is connected to the through hole 51.

[0023] Preferably, a screw 41 is fixedly connected to one side of each side plate 4, and the screw 41 is threaded inside the crossbar 42;

[0024] The crossbar 42 is installed inside the through hole 51. The length of the crossbar 42 is the same as the transverse length of the through hole 51. The outer wall of the crossbar 42 is in contact with one end of the movable rod 43. The movable rod 43 is movably inserted into the mounting hole 52.

[0025] Preferably, the movable rod 43 and the crossbar 42 are connected by a semi-circular notch, and the length of the movable rod 43 is greater than the longitudinal length of the mounting hole 52.

[0026] Preferably, the inner wall of the rubber wheel 6 is provided with two sets of positioning holes 61, each set of positioning holes 61 consists of four holes, and the four positioning holes 61 in each set are equally spaced on the inner wall of the rubber wheel 6. The end of the movable rod 43 away from the crossbar 42 is inserted into the positioning hole 61, and each movable rod 43 has a matching positioning hole 61.

[0027] In practical use, when the rubber wheel 6 becomes excessively worn and needs to be replaced, firstly, the side plate 4 should be removed from the mounting bracket 3. Loosen the fastening bolts connecting the side plate 4 to the mounting bracket 3, and then carefully remove the side plate 4.

[0028] Next, the rubber wheel 6 needs to be secured to prevent it from rolling or shifting during subsequent operations. This can be achieved using a special clamp or by placing obstructions around the rubber wheel 6. After securing the rubber wheel 6, rotate one of the side plates 4. The side plate 4 and the screw 41 are integrated; when the side plate 4 rotates, the screw 41 rotates synchronously. The crossbar 42 has a threaded structure that matches the screw 41. As the screw 41 continues to rotate, the rotating side plate 4 gradually detaches from the crossbar 42 under the action of the threads.

[0029] After one side plate 4 detaches from the crossbar 42, pull the other side plate 4. Since the crossbar 42 is connected to the wheel hub 5, the pulling force on the side plate 4 is transmitted to the crossbar 42, which then gradually pulls the crossbar 42 out of the wheel hub 5. After the crossbar 42 is pulled out, place the wheel hub 5 horizontally on the operating table. Adjust the angle by slightly tilting the wheel hub 5. One end of the movable rod 43 is inserted into the positioning hole 61 for positioning. When the wheel hub 5 is tilted, the supporting force on the movable rod 43 changes. Under the combined action of gravity and external force, the movable rod 43 can smoothly detach from the positioning hole 61. At this time, the original relatively fixed structure between the rubber wheel 6 and the wheel hub 5 is released, so the rubber wheel 6 can be easily removed from the wheel hub 5, making the disassembly of the rubber wheel 6 more convenient.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
