Description

Technical Field

[0001] This utility model relates to the field of tensioning wheels, specifically a replaceable tensioning wheel. Background Technology

[0002] An automotive tensioner is a device used to adjust the tension of the engine belt, ensuring the normal and stable operation of the transmission system. By maintaining appropriate tension, it prevents belt slippage, thereby extending the belt's lifespan and improving the efficiency and reliability of the transmission system. Existing tensioners are constantly subjected to various forces and frequent operation during use. Internal components such as rolling bearings and springs gradually wear down. After prolonged operation, the bearings may be damaged, leading to abnormal vibration and noise during operation, and making it impossible to accurately control the belt tension, requiring replacement. Tensioners are usually fixed by multiple screws, which are often very tight and require considerable force to loosen, making installation and disassembly cumbersome and causing certain disadvantages in the user experience. Therefore, we propose a replaceable tensioner. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This embodiment is a replaceable tensioner.

[0022] like Figure 1-4 As shown, the device includes a tensioning wheel 1, a connecting frame 2 on the lower outer surface of the tensioning wheel 1, and an installation / removal mechanism 3 on the upper outer surface of the tensioning wheel 1. The installation / removal mechanism 3 includes a through groove 4, a fixing post 5, a T-shaped insert 6, a groove 7, a slot 8, a first rubber ring 9, a second rubber ring 10, a slot 11, an insert plate 12, a connecting rod 13, a fixing rod 14, a hole groove 15, and a spring 16. The fixing post 5 is located on one side of the upper outer surface of the connecting frame 2, the T-shaped insert 6 is located at the upper end of the fixing post 5, the groove 7 is opened on the upper outer surface of the T-shaped insert 6, the slot 8 is opened on the upper outer surface of the fixing post 5, and both sets of second rubber rings 10 are located at the lower end of the inner wall of the slot 8.

[0023] Both sets of first rubber rings 9 are located at the lower end of the outer wall of the T-shaped insert 6. The fixing rod 14 is located in the middle of the groove 7. The two sets of slots 11 are respectively opened at the upper ends of the outer walls of the slot 8. The two sets of connecting rods 13 are respectively located on both sides of the groove 7. The insert plate 12 is located on the lower outer surface of the connecting rod 13. The hole slot 15 is opened on one side of the outer surface of the connecting rod 13. The spring 16 is located between the two sets of connecting rods 13. The through slot 4 is opened in the middle of the tension wheel 1. The tension wheel 1 is inserted into the fixing post 5 through the through slot 4. The T-shaped insert 6 is inserted into the slot 8. The first rubber ring 9 and the second rubber ring 10 are meshed with each other. The connecting rod 13 is slidably connected to the groove 7. The connecting rod 13 is slidably connected to the fixing rod 14 through the hole slot 15. The two sets of connecting rods 13 are elastically connected by the spring 16. The insert plate 12 is inserted into the slot 11.

[0024] It should be noted that this utility model is a replaceable tensioning wheel. By pressing two sets of connecting rods 13 inside the T-shaped insert 6, the connecting rods 13 are driven to slide along the fixed rod 14 through the slot 15, compressing the spring 16, and driving the insert plate 12 to slide along the groove 7. The insert plate 12 is then removed from the slot 11, and the T-shaped insert 6 is pulled upwards, causing the T-shaped insert 6 to slide along the slot 8. At the same time, the first rubber ring 9 and the second rubber ring 10 move alternately, thereby removing the T-shaped insert 6. The tensioning wheel 1 is then pulled, and it slides along the fixed post 5 under the action of the through groove 4, allowing the tensioning wheel 1 to be removed and replaced. This makes it convenient to install and replace the tensioning wheel 1, avoiding damage to the tensioning wheel 1 and affecting its use. It can limit and fix the T-shaped insert 6, and the mutual meshing of the first rubber ring 9 and the second rubber ring 10 can further enhance the placement stability of the T-shaped insert 6.
