Description

Technical Field

[0001] This utility model relates to the field of pipeline detector technology, specifically a tensioning structure for a transmission belt. Background Technology

[0002] With the development of society and the economy, the use of automated equipment in industrial production is becoming increasingly common. Replacing manual labor with automated equipment can effectively improve efficiency and reduce costs. Among these automated equipment components, transmission belts are fundamental. However, current transmission belts are prone to a decrease in tension after prolonged use, severely impacting transmission efficiency.

[0003] Therefore, to ensure the transmission belt maintains its smooth operation over extended periods, existing technologies often employ tensioning structures. However, these existing tensioning structures have drawbacks. As the tensioning mechanism tightens, it eventually reaches its limit. At this point, the belt can no longer be tightened further, indicating excessive looseness. Furthermore, existing tensioning structures lack any warning function when this limit is reached, preventing workers from promptly notifying them of the need to replace the belt. This can easily lead to slippage and unnecessary economic losses. Therefore, an improved tensioning structure for transmission belts is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a tensioning structure for transmission belts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensioning structure for a transmission belt, comprising a fixed plate, on both sides of the fixed plate surface being movably arranged via a rotating shaft, a transmission belt being sleeved between the transmission rollers, and a tensioning mechanism for tensioning the transmission belt being arranged on the fixed plate surface between the transmission rollers, the tensioning mechanism comprising a mounting plate, a slide rail, a slider, and a tensioning roller, the mounting plate being fixedly arranged on the fixed plate surface between the transmission rollers, the slide rail being fixedly arranged on both sides of the mounting plate surface, the slider being movably engaged on the slide rail surface, the tensioning roller being movably arranged on the slider surface via a rotating shaft, and a prompting mechanism for tension level alarm being arranged between the tensioning roller and the mounting plate.

[0006] Preferably, the prompting mechanism includes a connecting ring, a groove, and a connecting piece. A connecting ring is fixedly provided on one side of the tension roller surface, and a plurality of grooves are evenly provided on the surface of the connecting ring. A connecting piece is fixedly provided on one side of the mounting plate surface. When the transmission belt of this device becomes loose during use, the spring in a compressed state can push the tension roller to move upward. At this time, the tension roller can tighten the transmission belt sleeved on the surface of the transmission roller, ensuring the fit between the transmission belt and the transmission roller.

[0007] Preferably, the connecting piece is made of an elastic metal material. When the connecting ring is rotated, the connecting piece made of elastic metal material can automatically and quickly reset under its own elasticity, so that it can continuously contact the connecting ring to emit a specific prompt sound.

[0008] Preferably, a bell is fixedly provided on the surface of the connecting piece. The bell can increase the volume of the alarm sound when the connecting piece is vibrated by the connecting ring. The closer the bell is to the root of the connecting piece, the less sensitive it is, because the vibration amplitude of the connecting piece is the smallest at the root. The specific position can be designed and installed as needed. Of course, the bell can also be installed or not installed.

[0009] Preferably, a telescopic rod is fixedly provided at the lower end of the mounting plate, and the movable end of the telescopic rod is fixedly connected to the slider. A spring is sleeved on the outer surface of the telescopic rod. The spring of this device is in a compressed state, which can push the telescopic rod to have an elongation tendency, thereby pushing the tension roller to move upward continuously to ensure that the transmission belt cup is tensioned.

[0010] Preferably, the surface of the tension roller is in contact with the surface of the transmission belt, and the tension roller can ensure that the transmission belt is tightened and sleeved on the surface of the transmission roller.

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

[0012] 1. As the tension roller moves upward, the connecting ring gradually approaches the connecting plate. During use, the connecting ring rotates along with the tension roller. As the tension roller moves upward, the surface of the continuously rotating connecting ring comes into contact with the connecting plate. At this time, the continuously rotating connecting ring, in conjunction with the groove, causes the connecting plate to oscillate continuously. This provides a specific indication to the operator that the tension of the tension roller is approaching its limit, the transmission belt is too loose, and it needs to be replaced or repaired.

[0013] 2. The indicator mechanism of this utility model does not require a power supply, circuit, sensor or other structure, and can be reused repeatedly. This not only reduces costs but also extends the lifespan, making it easy to promote and use. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a tensioning structure for a transmission belt, including a fixed plate 1. Transmission rollers 2 are movably mounted on both sides of the fixed plate 1 via rotating shafts. A transmission belt 13 is sleeved between the transmission rollers 2. A tensioning mechanism for tensioning the transmission belt 13 is provided on the surface of the fixed plate 1 between the transmission rollers 2. The tensioning mechanism includes a mounting plate 3, a slide rail 4, a slider 5, and a tensioning roller 6. The mounting plate 3 is fixedly mounted on the surface of the fixed plate 1 between the transmission rollers 2. Slide rails 4 are fixedly mounted on both sides of the mounting plate 3. A slider 5 is movably engaged on the surface of the slide rail 4. A tensioning roller 6 is movably mounted on the surface of the slider 5 via a rotating shaft. A tensioning alarm mechanism for tension level is provided between the tensioning roller 6 and the mounting plate 3.

[0021] The prompting mechanism includes a connecting ring 7, a groove 8, and a connecting piece 9. A connecting ring 7 is fixedly disposed on one side of the surface of the tension roller 6. A plurality of grooves 8 are evenly distributed on the surface of the connecting ring 7. A connecting piece 9 is fixedly disposed on one side of the surface of the mounting plate 3. When the transmission belt 13 of this device becomes loose during use, the spring 12, which is in a compressed state, can push the tension roller 6 to move upward. At this time, the tension roller 6 can tighten the transmission belt 13 sleeved on the surface of the transmission roller 2, ensuring the fit between the transmission belt 13 and the transmission roller 2. As the tension roller 6 moves upward, the connecting ring 7 will gradually move closer to the connecting piece 9. The connecting ring 7 will rotate together with the tension roller 6 during use. As the tension roller 6 moves upward, the surface of the continuously rotating connecting ring 7 will come into contact with the connecting piece 9. At this time, the continuously rotating connecting ring 7, in conjunction with the groove 8, will cause the connecting piece 9 to swing continuously. This can produce a specific prompt to indicate to the staff that the tension of the tension roller 6 is about to reach its limit and the transmission belt 13 is too loose and needs to be replaced or repaired.

[0022] The connecting piece 9 is made of elastic metal material. When the connecting ring 7 is rotated, the connecting piece 9 made of elastic metal material can automatically and quickly reset under its own elasticity, so that it can continuously contact the connecting ring 7 to emit a specific prompt sound.

[0023] A bell 10 is fixedly installed on the surface of the connecting piece 9. The bell 10 can increase the volume of the beeping sound when the connecting piece 9 is vibrated by the connecting ring 7. The closer the bell 10 is to the root of the connecting piece 9, the less sensitive it is, because the vibration amplitude of the connecting piece 9 is the smallest at the root. The specific position can be designed and installed as needed. Of course, the bell 10 can also be installed or not installed.

[0024] A telescopic rod 11 is fixedly installed at the lower end of the mounting plate 3. The movable end of the telescopic rod 11 is fixedly connected to the slider 5. A spring 12 is sleeved on the outer surface of the telescopic rod 11. The spring 12 of this device is in a compressed state, which can push the telescopic rod 11 to have an elongation tendency, thereby pushing the tension roller 6 to move upward continuously to ensure that the transmission belt 13 cup is tensioned.

[0025] The surface of the tension roller 6 is in contact with the surface of the transmission belt 13, and the tension roller 6 can ensure that the transmission belt 13 is tightened and sleeved on the surface of the transmission roller 2.

[0026] Working principle: When using this device, the spring 12 is in a compressed state, which pushes the telescopic rod 11 to extend, thereby pushing the tension roller 6 to move upward continuously to ensure that the transmission belt 13 is tensioned. As the transmission belt 13 is used, it will gradually loosen. The compressed spring 12 can then push the tension roller 6 upward, which will tighten the transmission belt 13 fitted on the surface of the transmission roller 2, ensuring the fit between the transmission belt 13 and the transmission roller 2. As the tension roller 6 moves upward, the connecting ring 7 will gradually approach the connecting piece 9. The connecting ring 7 will rotate with the tension roller 6 during use. As the tension roller 6 moves upward, the surface of the connecting ring 7 will come into contact with the connecting piece 9. At this time, the continuously rotating connecting ring 7, in conjunction with the groove 8, will cause the connecting piece 9 to swing continuously. This will provide a specific indication to the operator that the tension of the tension roller 6 is about to reach its limit and the transmission belt 13 is too loose, requiring replacement or repair.

[0027] Furthermore, the indicator mechanism of this device requires no power supply, circuitry, sensors, or other structural components, and can be reused repeatedly. This not only results in low cost and long lifespan, but also facilitates its widespread adoption.
