Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to a rubber wheel used for elevators. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. When the elevator is in operation, the movement of the car body is limited by the elevator rubber wheels. Elevator rubber wheels refer to rubber products installed on the elevator guide rails to support and guide the operation of the elevator. They are usually ring-shaped rubber wheels installed on the elevator handrails or guide rails to reduce the vibration and noise of the elevator during operation and ensure the smooth operation of the elevator.

[0003] In the prior art, when the elevator rubber wheel slides smoothly inside the guide rail, the elevator rubber wheel can limit the elevator car, so that the elevator car is sufficiently stable when moving up and down. However, the wheel body and the rubber layer of most existing elevator rubber wheels are often tightly connected together by bonding or other connection methods. This means that when the rubber layer ages and needs to be replaced, the rubber layer can only be replaced together with the wheel body, thereby increasing the cost of replacing and maintaining the elevator rubber wheel, and increasing the waste of the wheel body when replacing the wheel body. Therefore, a rubber wheel for an elevator is now proposed. Utility Model Content

[0036] Reference Figure 3 and Figure 4 The limiting mechanism 5 includes a fixed block 51, a spring 53 and a clamping block 54. The fixed block 51 is fixedly connected to one side of the connecting plate 2. A mounting groove 52 is provided on one side of the fixed block 51. The spring 53 is fixedly connected inside the mounting groove 52. The clamping block 54 is fixedly connected to one end of the spring 53, and the clamping block 54 is slidably connected inside the mounting groove 52. A clamping groove 55 is provided on one side of the mounting ring block 3. The fixed block 51 is movably inserted into the inside of the clamping groove 55, and the clamping block 54 is movably clamped into the inside of the clamping groove 55. More specifically, the connecting plate 2 can play the role of installing and fixing the fixing block 51, and the fixing block 51 can connect the spring 53 and the clamping block 54 through the installing groove 52, and when the fixing block 51 is inserted into the inside of the clamping groove 55, the installing ring block 3 can smoothly limit the fixing block 51 through the clamping groove 55, and clamp the clamping block 54 through the clamping groove 55, thereby increasing the stability of the connection between the fixing block 51 and the installing ring block 3. At the same time, the spring 53 can drive the clamping block 54 to reset through its own elasticity after being subjected to pressure, and after the clamping block 54 is smoothly clamped into the inside of the clamping groove 55, it is convenient for the subsequent connecting mechanism 6 to connect and install the connecting plate 2 and the installing ring block 3, and the setting of the limiting mechanism 5 can effectively increase the convenience of installing, connecting and disassembling the connecting plate 2 and the installing ring block 3.

[0037] Reference Figure 5-7 The connection mechanism 6 includes a bolt 62 and a limiting nut 63. A thread groove 61 is provided on one side of the connection plate 2 and the mounting ring block 3. The bolt 62 is threadedly connected to the inside of the thread groove 61, and the outer side of the bolt 62 is threadedly connected to the limiting nut 63. More specifically, the bolt 62 can be smoothly connected to the inside of the thread groove 61 to achieve the connection and installation of the connection plate 2 and the mounting ring block 3, so that the connection plate 2 and the mounting ring block 3 can be firmly connected together. Since the mounting ring block 3 and the rubber layer 4 are fixedly connected, the rubber layer 4 can be smoothly used with the connection plate 2. At the same time, the setting of the limiting nut 63 can effectively increase the stability of the bolt 62 during long-term use and reduce the possibility of the bolt 62 loosening.

[0038] Reference Figure 4 The fixing block 51 is located inside the mounting groove 52 and is fixedly connected with a rebound rubber block 7. One end of the rebound rubber block 7 is fixedly connected to the clamping block 54, and the rebound rubber block 7 is arranged on the inner side of the spring 53. More specifically, the fixing block 51 can cooperate with the clamping block 54 to realize the installation of the rebound rubber block 7, and the rebound rubber block 7 can assist the resetting of the clamping block 54 through its own elasticity, and realize the limiting of the spring 53, thereby increasing the stability of the spring 53 during extension and contraction, and reducing the possibility of deformation of the spring 53 during extension and contraction.

[0039] Reference Figure 4A plug-in block 9 is fixedly connected to one side of the fixed block 51, a slot 8 is opened inside the mounting ring block 3, and the slot 8 is communicated with the card slot 55, and the plug-in block 9 is movably connected to the inside of the slot 8. More specifically, the fixed block 51 can be connected to the plug-in block 9, and when the plug-in block 9 is carded to the inside of the slot 8, the plug-in block 9 can increase the stability of the fixed block 51 after being connected to the inside of the card slot 55 through the connection relationship between itself and the slot 8, thereby improving the firmness of the connecting plate 2 and the mounting ring block 3 after being connected during use.

[0040] Reference Figure 4 A slide groove 10 is provided inside the fixed block 51, and the slide groove 10 is connected to the mounting groove 52. A slider 11 is fixedly connected to one side of the block 54, and the slider 11 is slidably connected inside the slide groove 10. More specifically, the block 54 can be connected to the slider 11, and the fixed block 51 can limit the slider 11 and the block 54 through the slide groove 10, thereby effectively increasing the stability of the block 54 when sliding and moving, and reducing the possibility of the block 54 being offset when moving.

[0041] Reference Figure 1 and Figure 7 A rubber gasket 14 is provided on the outer side of the bolt 62. The rubber gasket 14 is provided between the limiting nut 63 and the mounting ring block 3. The rubber gasket 14 is used to increase the stability of the bolt 62. More specifically, the setting of the rubber gasket 14 enables the limiting nut 63 to be connected to the outer side of the bolt 62 to increase the stability of the bolt 62. The rubber gasket 14 can effectively assist the limiting nut 63, increase the stability of the connection between the limiting nut 63 and the bolt 62, and further reduce the possibility of the bolt 62 loosening.

[0042] Reference Figure 5 and Figure 6A hollow groove 13 is provided on one side of the mounting ring block 3 , and a fixing rod 12 is fixedly connected to one side of the connecting plate 2 . The fixing rod 12 is movably inserted into the inside of the hollow groove 13 , and the length of the fixing rod 12 is greater than the width of the fixing block 51 . More specifically, the connecting plate 2 can also play a role in installing and fixing the fixing rod 12. After the fixing rod 12 is inserted into the inside of the hollow groove 13, the connection between the hollow groove 13 and the fixing rod 12 can play a limiting role in the subsequent connection between the connecting plate 2 and the mounting ring block 3, which not only enables the fixing block 51 to be smoothly connected to the inside of the card slot 55, but also makes it difficult for the connecting plate 2 and the mounting ring block 3 to shake or slide when the staff firmly connects the connecting plate 2 and the mounting ring block 3 together through the connecting mechanism 6, thereby increasing the stability of the connection between the connecting plate 2 and the mounting ring block 3. The length of the fixing rod 12 is greater than the width of the fixing block 51, which enables the fixing rod 12 to effectively limit the connection between the connecting plate 2 and the mounting ring block 3 through the connection between itself and the hollow groove 13, and it is not easy to fail to achieve the limiting effect due to insufficient distance between itself.

[0043] The implementation principle of the utility model is as follows: when the mounting ring block 3 needs to be connected to the outer side of the wheel body 1 for use, the staff can put the mounting ring block 3 on the outer side of the wheel body 1 and push the mounting ring block 3 to one side of the connecting plate 2. When the mounting ring block 3 moves to a certain distance, the fixing rod 12 will be inserted into the inside of the hollow groove 13, and the subsequent push will cause the fixing block 51 to be inserted into the inside of the card slot 55, and at this time, the mounting ring block 3 will squeeze the card block 54, so that the card block 54 moves to the inside of the mounting groove 52, and the card block 54 will press the spring 55 while moving. 3 is squeezed, and when the connecting plate 2 and the mounting ring block 3 are fitted, the clamping block 54 will be reset by the elasticity of the spring 53 and the rebound rubber block 7, and smoothly clamped into the inside of the clamping groove 55. At this time, the clamping block 54 can limit the connection between the connecting plate 2 and the mounting ring block 3, and then the staff can connect the bolt 62 to the inside of the thread groove 61, and connect the limiting nut 63 and the rubber gasket 14 to the outside of the bolt 62. After completing the above operations, the connection between the connecting plate 2 and the mounting ring block 3 can be achieved, and the rubber layer 4 and the wheel body 1 can also be used smoothly.

[0044] When the rubber layer 4 needs to be replaced, the staff can remove the bolt 62 from the inside of the threaded groove 61, and after removing it, pull the mounting ring block 3 or the rubber layer 4 with force to pull the mounting ring block 3 out from the outside of the clamping block 54, and cancel the clamping connection between the clamping block 54 and the clamping groove 55 by pulling, and at the same time, the fixing rod 12 will also be separated from the hollow groove 13. At this time, the rubber layer 4 can be disassembled, and when a new rubber layer 4 needs to be installed, it is only necessary to repeat the above-mentioned installation operation of the mounting ring block 3 and the wheel body 1. This can solve the problem that the wheel body 1 and the rubber layer 4 of most existing elevator rubber wheels are often tightly connected together by bonding or other connection methods. This means that when the rubber layer 4 ages and needs to be replaced, the rubber layer 4 can only be replaced together with the wheel body 1, thereby increasing the cost of replacing and maintaining the elevator rubber wheel.

[0045] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
