Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, specifically an adjustable retractable tensioner. Background Technology

[0002] A retractable tensioner is a tool or device that uses mechanical structures or manual operation to retract or tighten an object to achieve the purpose of fixing, securing, or adjusting its state. In cargo transportation, it tightens and secures ropes or nets to prevent goods from swaying or shifting. In construction, it tightens scaffolding cables and protective nets to ensure structural stability. In daily use, it tightens tent securing ropes, clothes rack wire ropes, etc., to ensure the stable installation or use of items. In addition, some retractable tensioners also have the function of adjusting the tightness, which can precisely control the tension force according to actual needs to ensure the safety and stability of the fixed object.

[0003] Existing tensioners are inconvenient to adjust during use. Some products use a fixed-position design and lack continuous fine-tuning function, making it impossible to accurately adapt the tightness to different objects or scenarios. Manually operated tensioners mostly rely on manual turning of knobs or levers, which is time-consuming and laborious, and the force is difficult to control. Some mechanical structures have problems with jamming and sticking, which makes it inconvenient to adjust and leads to poor fixing effect. If it is too loose, the fixed object may loosen and shift, increasing safety hazards. To address these issues, we propose an adjustable tensioner. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable retractable tensioner to solve the problems mentioned in the background art, such as the inconvenience of adjusting existing retractable tensioners during use, the lack of continuous fine-tuning function in some products with fixed gears, and the inability to accurately adapt the tightness to different objects or scenarios; the manual operation of tensioners mostly relies on manual rotation of knobs or levers, which is time-consuming and laborious, and the force is difficult to control; and the mechanical structure of some has problems of jamming and sticking, which makes adjustment inconvenient and results in poor fixing effect, and excessive looseness can easily cause the fixed object to loosen and shift, increasing safety hazards.

The adjustment mechanism includes a limiting groove located inside the pressure plate. A rotating shaft is rotatably connected inside the limiting groove. A rod is inserted laterally inside the rotating shaft. A ratchet gear is rotatably connected to the outside of the rotating shaft. A baffle is meshed with the top of the ratchet gear.

[0007] The buffer mechanism is located inside the motherboard and is used to dampen shocks when the device is tightened.

[0008] The top of the baffle is fixedly connected to a first spring, and the top of the first spring is fixedly connected to a fixing plate.

[0009] The buffer mechanism includes a base plate that is slidably connected inside the motherboard, a buffer plate that is fixedly connected to the top of the base plate, a buffer rod that is slidably connected to one side of the buffer plate, and a cross plate that is fixedly connected to one side of the buffer rod.

[0014] This utility model has at least the following beneficial effects:

[0015] In use, this invention features an adjustment mechanism that allows the device to be tightened by pressing down on the pressure plate, which in turn rotates the ratchet gear via a rotating shaft. When the pressure plate is pulled up, a baffle engages with the ratchet gear to prevent loosening. The baffle's position can be adjusted using a first spring and a fixing plate, enhancing the ease of adjustment.

During use, the operator can tighten the device by pressing down the pressure plate 104, which drives the ratchet gear 202 to rotate via the rotating shaft 201. When the pressure plate 104 is pulled up, the baffle 204 can engage with the outer periphery of the ratchet gear 202 to prevent the device from loosening. In addition, the device can adjust the engagement position of the baffle 204 by the first spring 205 and the fixing plate 206, improving the convenience of device adjustment.
