Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a novel adjustable tensioner structure. Background Art

[0002] In modern industrial production and daily life, tensioners, as an important fastening tool, are widely used in various scenarios, such as mechanical assembly, construction, transportation, etc.

[0003] However, the traditional ratchet mechanism has a limited adjustment range and cannot be fine-tuned according to specific needs, resulting in the inability to achieve the ideal tensioning effect in some application scenarios. When multiple ratchets are used, due to their independent operation, they are prone to asynchrony, which can cause jamming or loosening problems, affecting the overall stability and reliability. In addition, the existing tensioner structure is often difficult to disassemble and maintain, especially when there is a problem with the ratchet part, it is difficult to effectively maintain and repair it, affecting the long-term operation of the equipment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a novel adjustable tensioner structure.

[0005] The utility model is implemented by the following technical scheme: an adjustable new tensioner structure, including a side baffle, the inner wall of the side baffle is provided with a reinforced inner plate, the outer surface of the side baffle is provided with a ratchet positioning cover, the surface of the reinforced inner plate is provided with a support plate, the surface of the support plate is provided with a transmission horizontal axis, the inner wall of the side baffle is provided with a ratchet body, the surface of the side baffle is provided with an oblique groove, the right end of the ratchet body is provided with a locking block, the right end of the locking block is provided with a handle, the right end of the side baffle is provided with a handle, the surface of the handle is provided with sweat-absorbing cotton, the left end of the ratchet positioning cover is provided with a bolt, the right end of the locking block is provided with a spring, and the right end of the ratchet positioning cover is provided with a notch.

[0006] Through the above technical solution, the combination of the reinforced inner plate and the support plate enhances the structural stability of the entire tensioner, prevents deformation or breakage during use, can effectively disperse stress, and reduce wear on key parts, thereby extending the service life of the tensioner. The threaded connection design of the ratchet positioning cover makes it easy for personnel to disassemble it, thereby facilitating personnel to disassemble the reinforced inner plate and the support plate.

[0007] As a further improvement of the above solution, two side baffles are provided, and ends of the two side baffles that are close to each other are fixedly connected to ends of the reinforced inner plate that are away from each other.

[0008] Through the above technical solution, the direct mechanical connection between the transmission horizontal shaft and the ratchet body reduces the energy loss in the power transmission process and improves the overall efficiency of the system. By driving the ratchet bodies at both ends to rotate through the transmission horizontal shaft, it can ensure that the movements of the two ratchet bodies are highly consistent, avoiding jamming or loosening problems caused by asynchrony. By controlling the rotation angle and speed of the transmission horizontal shaft, the rotation degree of the ratchet body can be easily adjusted, thereby achieving fine adjustment and control of the tightening force.

[0009] As a further improvement of the above scheme, there are two ratchet positioning covers, four notches are provided, four notches are opened at one end of the two ratchet positioning covers away from each other, two bolts are provided, and the two bolts are threadedly connected to the two ratchet positioning covers through the four notches.

[0010] Through the above technical solution, the ratchet positioning covers on both sides are independently detachable, which facilitates the inspection and maintenance of the internal structure and reduces the difficulty and time of maintenance.

[0011] As a further improvement of the above scheme, two oblique grooves are provided, and two oblique grooves are opened on the outer surfaces of the two side baffles. Two springs are provided, and the left ends of the two springs are fixedly connected to the right end of the locking block, and the right ends of the two springs are fixedly connected to the right ends of the inner walls of the two oblique grooves.

[0012] Through the above technical solution, through a fixed connection, it is ensured that the rotation of the transmission horizontal axis can synchronously drive the ratchet bodies at both ends to perform the same movement, thereby realizing synchronous adjustment of the two ends of the tensioner, improving the efficiency and accuracy of the operation, when the ratchet body rotates clockwise or counterclockwise, it will drive the tensioning component connected to it to retract and release, thereby adjusting the tension of the tensioner, and two springs are set, when the staff pulls the handle to reset the rope, the handle can be reset through the elastic force of the spring, thereby improving the practicality of the equipment.

[0013] As a further improvement of the above scheme, two oblique grooves are provided, and two oblique grooves are opened on the outer surfaces of the two side baffles. Two springs are provided, and the left ends of the two springs are fixedly connected to the right end of the locking block, and the right ends of the two springs are fixedly connected to the right ends of the inner walls of the two oblique grooves.

[0014] Through the above technical solution, the detachable design of the ratchet positioning cover allows the reinforced inner plate and the support plate to be easily removed, which is convenient for the inspection and maintenance of the equipment, and further facilitates the maintenance of the ratchet body by personnel, thereby extending the service life of the parts.

[0015] As a further improvement of the above scheme, the two oblique grooves are slidably connected to the ends of the locking block that are away from each other, the left end of the locking block is transmission connected to the right end of the ratchet body, and the right end of the locking block is fixedly connected to the left end of the handle.

[0016] Through the above technical scheme, the opening of the oblique groove plays a precise guiding role for the locking block, so that the locking block can slide along a predetermined trajectory in the groove, ensuring the contact and locking effect between the locking block and the ratchet body. This guiding effect not only improves the movement accuracy of the locking block, but also reduces the possibility of the locking block being offset or stuck during the sliding process, thereby improving the reliability of the equipment and the smoothness of operation. Through the cooperation of the oblique groove and the locking block, the self-locking function of the ratchet body can be realized. When the ratchet body rotates clockwise or counterclockwise, the locking block will slide in the oblique groove to prevent the ratchet body from rotating in the opposite direction, thereby realizing unidirectional rotation and self-locking functions.

[0017] As a further improvement of the above solution, the left end of the handle is fixedly connected to the right ends of the two side baffles, and a plurality of sweat-absorbing cotton pads are provided, and the ends of the plurality of sweat-absorbing cotton pads close to each other are fixedly connected to the surface of the handle.

[0018] Through the above technical solution, by setting up a number of sweat-absorbing cottons, when the staff are working outdoors, some of the staff will sweat on their palms when the outdoor temperature is too high, and the sweat-absorbing cottons can absorb the sweat to avoid slipping when pulling the handle.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model provides a transmission transverse axis and controls the rotation angle and speed of the transmission transverse axis, so that the personnel can finely adjust the tightening force according to actual needs. At the same time, the transmission transverse axis drives the ratchet bodies at both ends to rotate, which can ensure that the movements of the two ratchet bodies are highly consistent. The synchronous rotation mechanism avoids the problem of jamming or loosening caused by asynchronism, and the reinforced inner plate and the support plate can be removed by removing the ratchet positioning cover. The personnel can more conveniently access the ratchet body and perform necessary maintenance work, thereby ensuring the long-term reliable operation of the ratchet body. By providing a plurality of sweat-absorbing cottons, when the staff work outdoors, some of the staff sweat in the palms when the outdoor temperature is too high, and the sweat-absorbing cottons can absorb sweat to avoid slipping when pulling the handle. Two springs are provided, so that when the staff pulls the handle to reset the rope, the handle can be reset by the elastic force of the springs, thereby improving the practicability of the equipment.
