Description

Technical Field

[0001] This utility model relates to the field of garden machinery technology, specifically a detachable cloth-covered V-belt for garden machinery. Background Technology

[0002] In the field of garden machinery, the performance of the cloth-wrapped V-belt, as a key component for power transmission, directly affects the working efficiency and stability of garden machinery.

[0003] Disassembling the V-belts used in existing garden machinery typically requires the use of multiple tools such as wrenches and screwdrivers to disassemble the entire transmission system. However, this presents several problems in practical applications. Firstly, the disassembly process is cumbersome, often requiring multiple tools and consuming significant time and manpower. This greatly impacts the efficiency of daily maintenance and repair of garden machinery, leading to prolonged equipment downtime and reduced work efficiency. Secondly, the tension adjustment methods for the V-belts are not flexible enough, often employing fixed tensioning structures that are difficult to adjust precisely according to actual working conditions. Excessive tension increases wear on the V-belt and pulleys, shortening component lifespan; insufficient tension easily leads to slippage, reducing transmission efficiency and even causing power transmission interruption.

[0023] 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.

[0024] Example

[0025] Please see Figure 1-6 This utility model provides a technical solution: a detachable fabric-covered V-belt for garden machinery, comprising:

[0026] The housing 1 has a quick-release device 2 rotatably connected to its inner wall. The quick-release device 2 is disassembled by rotation. The inner wall of the housing 1 is slidably connected to a tension device 3. The tension device 3 pushes the fabric V-belt by sliding. The inner wall of the housing 1 is rotatably connected to a main shaft 4. The quick-release device 2 and the main shaft 4 located on the outer wall of the housing 1 are used to fix the fabric V-belt. The tension device 3 is used to control the tension of the fabric V-belt.

[0027] The quick-release device 2 includes a rotating rod 20, a fixing block 21 fixedly connected to the outer wall of the rotating rod 20, a sliding block 22 slidably connected to the outer wall of the rotating rod 20, a limiting ring 23 fixedly connected to the outer wall of the sliding block 22, and locking blocks 24 symmetrically fixedly connected to the outer wall of the limiting ring 23. The outer walls of the locking blocks 24 are arranged in a circumferential array along the central axis of the limiting ring 23. The outer wall of the rotating rod 20 is rotatably connected to the inner wall of the housing 1, and the outer wall of the limiting ring 23 is slidably connected to the inner wall of the fixing block 21 through a sliding groove. The sliding groove is formed in the fixing block 21. The inner wall of the card block 24 is rotatably connected to the inner wall of the fixed block 21. When installing the fabric-covered V-belt, it is placed on the outer wall of the fixed block 21 in the main rotating shaft 4 and quick-release device 2. Since the inner wall of the sliding block 22 is slidably connected to the outer wall of the rotating rod 20, the sliding block 22 is slid along the outer wall of the rotating rod 20 towards the fixed block 21. Since the outer wall of the limiting ring 23 is fixedly connected to the outer wall of the sliding block 22, the limiting ring 23 moves synchronously when the sliding block 22 slides. The limiting ring 23 slides on the inner wall of the fixed block 21 through the sliding groove.

[0028] A compression spring 25 is fixedly connected to the inner wall of the locking block 24. A spring pin 26 is fixedly connected to the end of the compression spring 25 away from the locking block 24. The outer wall of the spring pin 26 is slidably connected to the inner wall of the limiting ring 23. The end face of the spring pin 26 is spherical, and the spherical outer wall is slidably connected to the inner wall of the fixing block 21. When the limiting ring 23 slides, the locking block 24 located on the outer wall of the limiting ring 23 moves synchronously. When the locking block 24 is aligned with the corresponding position of the fixing block 21, the sliding ring is rotated. During this process, the limiting ring 23 and the locking block 24 rotate on the inner wall of the fixing block 21. The spring pin on the inner wall of the locking block 24 slides on the inner wall of the fixing block 21. The compression spring 25 pushes the spring pin 26, and the spherical end face of the spring pin 26 slides into the inner wall of the fixing block 21, thus realizing the stable installation of the wrapped V-belt.

[0029] The tension device 3 includes a limiting rod 30, and a push block 31 is rotatably connected to the outer wall of the limiting rod 30. The outer wall of the limiting rod 30 is slidably connected to the inner wall of the housing 1. The outer wall of the push block 31 is in contact with the fabric V-belt. When it is necessary to adjust the tension of the fabric V-belt, the operator pulls or pushes the handle 34. The handle 34 drives the pin 33 to slide in the connecting rod 32. Since the pin 33 is slidably connected to the locking strip 35, the locking strip 35 is arranged in a linear array along the outer wall of the housing 1. The pin 33 can be limited by the locking strip 35 at different positions during the movement.

[0030] A connecting rod 32 is fixedly connected to the outer wall of the limiting rod 30. A pin 33 is slidably connected to the inner wall of the connecting rod 32. A handle 34 is fixedly connected to the outer wall of the pin 33. A retaining strip 35 is symmetrically slidably connected to the outer wall of the pin 33. The outer wall of the connecting rod 32 is slidably connected to the outer wall of the housing 1. The outer wall of the handle 34 is slidably connected to the inner wall of the connecting rod 32. The outer wall of the retaining strip 35 is fixedly connected to the outer wall of the housing 1, and the outer walls of the retaining strip 35 are arranged in a linear array along the outer wall of the housing 1. The outer walls of the main rotating shaft 4, the fixing block 21, and the sliding block 22 are in contact with the fabric-covered V-belt. At the same time, the connecting rod 32 drives the limiting rod 30 to slide on the inner wall of the housing 1. The push block 31 on the limiting rod 30 moves accordingly, and the push block 31 pushes the fabric-covered V-belt, changing the tension of the fabric-covered V-belt. After adjustment, the pin 33 is limited by the retaining strip 35 to ensure that the fabric-covered V-belt maintains a suitable tension, improves transmission efficiency, and reduces slippage.

[0031] In use, the quick-release device 2 and the main rotating shaft 4 located on the outer wall of the housing 1 are used to fix the fabric-covered V-belt, and the tension device 3 is used to control the tightness of the fabric-covered V-belt.

[0032] When installing the fabric-covered V-belt, it is placed on the outer wall of the fixing block 21 in the main rotating shaft 4 and quick-release device 2. Since the inner wall of the sliding block 22 is slidably connected to the outer wall of the rotating rod 20, the sliding block 22 is slid along the outer wall of the rotating rod 20 towards the fixing block 21. Since the outer wall of the limiting ring 23 is fixedly connected to the outer wall of the sliding block 22, the limiting ring 23 moves synchronously when the sliding block 22 slides. The limiting ring 23 slides on the inner wall of the fixing block 21 through the groove.

[0033] When the limiting ring 23 slides, the locking block 24 located on the outer wall of the limiting ring 23 moves synchronously. When the locking block 24 is aligned with the corresponding position of the fixed block 21, the sliding ring is then rotated. During this process, the limiting ring 23 and the locking block 24 rotate on the inner wall of the fixed block 21. The pin on the inner wall of the locking block 24 slides on the inner wall of the fixed block 21. The compression spring 25 pushes the spring pin 26, and the spherical end face of the spring pin 26 slides into the inner wall of the fixed block 21, thus achieving a stable installation of the fabric-covered V-belt.

[0034] During disassembly, simply rotate the sliding block 22 to allow the spring pin 26 to slide out of the inner wall of the fixing block 21 until the locking block 24 slides out of the groove reserved in the fixing block 21. Then, the fabric-covered V-belt can be removed from the outer wall of the fixing block 21 and then removed from the outer wall of the main rotating shaft 4 in sequence.

[0035] When it is necessary to adjust the tension of the V-belt, the operator pulls or pushes the handle 34. The handle 34 causes the pin 33 to slide inside the connecting rod 32. Since the pin 33 is slidably connected to the retaining strip 35, the retaining strip 35 is arranged in a linear array along the outer wall of the housing 1. The pin 33 can be limited by the retaining strip 35 at different positions during the movement.

[0036] Simultaneously, the connecting rod 32 drives the limiting rod 30 to slide on the inner wall of the housing 1, and the push block 31 on the limiting rod 30 moves accordingly. The push block 31 pushes the fabric-covered V-belt, changing the tension of the fabric-covered V-belt. After adjustment, the pin 33 is limited by the retaining strip 35 to ensure that the fabric-covered V-belt maintains appropriate tension, improves transmission efficiency, and reduces slippage.
