Abstract
Description
Technical Field
[0001] This utility model relates to the field of engines, and in particular to an engine tensioner. Background Technology
[0002] An engine tensioner is a device used to maintain proper belt tension, ensuring close contact between the belt and pulleys and preventing slippage, detachment, or excessive wear. It typically consists of a pulley body, bearings, and an adjusting mechanism.
[0003] The existing engine tensioner adjustment mechanism is quite complex, and adjusting the belt tension requires the use of appropriate tools, which is very troublesome.
[0004] Therefore, it is necessary to provide a new engine tensioner to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an engine tensioner, which solves the problem that the adjustment mechanism of the existing engine tensioner is relatively complicated and requires the use of corresponding tools when adjusting the belt tension, which is very troublesome.
[0006] The engine tensioner provided by this utility model includes a side seat fixed to one side of the engine, a swing shaft movably disposed on one side of the side seat, a wheel body disposed on one side of the side seat, a bearing fixed inside the wheel body, and the top of the swing shaft being fixedly connected to the inner ring of the bearing.
[0007] In a preferred embodiment, a support seat is circumferentially fixed on the swing shaft, a plurality of first locking blocks are circumferentially fixed on the support seat, a limiting seat is fixed on one side of the side seat, a sliding shaft is slidably arranged on the limiting seat, and a second locking block is fixed on the sliding shaft, the second locking block being located between two first locking blocks.
[0008] In a preferred embodiment, a pull block is fixed on the slide shaft, and a spring is sleeved on the slide shaft. One end of the spring is fixed to the pull block, and the other end of the spring is fixed to the limiting seat.
[0009] In a preferred embodiment, the size of the second card block matches the distance between the two first card blocks.
[0010] In a preferred embodiment, the edges of the pull block are rounded.
[0011] The beneficial effects of this utility model are:
[0012] When the tension of the engine belt needs to be adjusted, the operator only needs to pull the pull block to move the sliding shaft. At this time, the second locking block disengages from the two first locking blocks. The swing shaft can be manually rotated to move the wheel. By changing the position of the wheel, the tension of the engine belt can be adjusted. After the adjustment is completed, the pull block is released, and the second locking block re-locks between the two first locking blocks under the action of the spring. At this time, the position of the wheel is fixed. The structure is simple and the operation is convenient. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 The main structural perspective view of the engine tensioner provided by this utility model Figure 1 ; Figure 2 The main structural perspective view of the engine tensioner provided by this utility model Figure 2 ; Figure 3 The main structural perspective view of the engine tensioner provided by this utility model Figure 3 .
[0019] In the specific implementation process, such as Figures 1-3As shown, the system includes a side seat 1 fixed to one side of the engine, a swing shaft 2 movably mounted on one side of the side seat 1, a wheel 3 mounted on one side of the side seat 1, a bearing 4 fixed inside the wheel 3, the top of the swing shaft 2 fixedly connected to the inner ring of the bearing 4, a support seat 11 circumferentially fixed on the swing shaft 2, several first locking blocks 5 circumferentially fixed on the support seat 11, a limit seat 6 fixed on one side of the side seat 1, a sliding shaft 7 slidably mounted on the limit seat 6, and a second locking block 8 fixed on the sliding shaft 7. The second locking block 8 is located between two first locking blocks 5. When the tension of the engine belt needs to be adjusted, the operator only needs to pull the pull block 9 to move the sliding shaft 7. At this time, the second locking block 8 disengages from between the two first locking blocks 5, and the swing shaft 2 rotates to move the wheel 3. The tension of the engine belt can be adjusted by changing the position of the wheel 3.
[0020] A pull block 9 is fixed on the sliding shaft 7, and a spring 10 is sleeved on the sliding shaft 7. One end of the spring 10 is fixed on the pull block 9, and the other end of the spring 10 is fixed on the limiting seat 6. The size of the second locking block 8 matches the distance between the two first locking blocks 5, ensuring that the second locking block 8 can be seamlessly inserted between the two first pulling blocks 5, and ensuring that the tensioning wheel will not wobble when in use. After adjusting the position of the wheel body 1, the pull block 9 is released. The edge of the pull block 9 is rounded to prevent the operator from being injured when pulling the pull block 9. Under the action of the spring 10, the second locking block 8 is re-engaged between the two first locking blocks 5, and the position of the wheel body 1 is fixed at this time.
[0021] The working principle of this utility model is as follows: When it is necessary to adjust the tension of the engine belt, the operator only needs to pull the pull block 9 to move the sliding shaft 7. At this time, the second locking block 8 disengages from the two first locking blocks 5. The swing shaft 2 is rotated to move the wheel body 3. By changing the position of the wheel body 3, the tension of the engine belt can be adjusted. After the adjustment is completed, the pull block 9 is released. Under the action of the spring 10, the second locking block 8 is re-locked between the two first locking blocks 5. At this time, the position of the wheel body 1 can be fixed.
[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
