Description

Technical Field

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

[0002] In modern industrial production and logistics transportation, the fixing and bundling of goods and equipment is a key link to ensure safety and efficiency. With the advancement of technology and the diversification of market demand, traditional ropes and simple tying methods can no longer meet the complex and changing working environment and professional fixing requirements. Therefore, various types of tensioners have appeared on the market, aiming to provide more efficient, convenient and reliable fixing solutions.

[0003] In the process of logistics transportation, the goods are tied and fixed by a tensioner, but most of the existing tensioners are fixed by hooking on an external object, and the fixing effect is not ideal. When subjected to external force, the hook is easy to slip off or loosen from the external object. Utility Model Content

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

[0005] The utility model is implemented by the following technical scheme: a tensioner structure, including a shell, the inner wall of the shell is provided with a stretching column, the lower surface of the shell is fixedly connected to a supporting plate, the outer surface of the stretching column is provided with a webbing, one end of the webbing is provided with a hook, the inner wall of the hook is rotatably connected to a fixed shaft, the two ends of the fixed shaft are fixedly connected to a limit plate, the inner wall of the limit plate is threadedly connected to a fastening bolt, and one end of the fastening bolt passes through the hook.

[0006] Through the above technical scheme, the setting of the stretching column can effectively guide and support the webbing, making it smoother during the tightening process, thereby improving the tightening efficiency. By fixing the webbing on the outer surface of the stretching column, the stress of the webbing during tightening can be more evenly distributed on the stretching column, avoiding damage caused by stress concentration. The contact area between the webbing and the stretching column is large, which can reduce the wear of the webbing during the tightening process and extend its service life. The front end of the hook is blocked by the limit plate to avoid looseness during connection.

[0007] As a further improvement of the above solution, there are two webbings, which are respectively arranged on both sides of the outer surface of the shell.

[0008] Through the above technical solution, the double webbing design can make the force of the tensioner more balanced when tightening, avoiding damage or failure caused by excessive force on a single webbing. The double webbing design can disperse the stress and reduce the wear of each webbing, thereby extending the service life of the tensioner.

[0009] As a further improvement of the above solution, the number of the hooks corresponds to the number of the webbings.

[0010] Through the above technical solution, by setting a hook, the webbing can be more conveniently connected to the object to be fixed, which simplifies the operation steps and improves work efficiency. In addition, the design of the hook allows the tensioner to be suitable for a variety of different fixing points, increasing its versatility and scope of application.

[0011] As a further improvement of the above solution, a baffle is fixedly connected to the surface of the shell, and a spring sheet is arranged inside the baffle.

[0012] Through the above technical solution, by finely adjusting the stretching degree of the spring sheet, accurate control of the tensioning force can be achieved, thereby improving the operating accuracy of the tensioner. The spring sheet can store energy when stretched and can rebound quickly when released, thereby providing a stable tensioning force.

[0013] As a further improvement of the above solution, a ratchet structure body is fixedly connected to the interior of the shell.

[0014] Through the above technical solution, the ratchet structure body can provide a stable transmission effect, ensuring that the tensioner will not slip or reverse during the tightening process. The ratchet structure has a one-way locking function, which can prevent the tensioner from loosening after tightening, ensuring the stability of the tightening state. The ratchet structure body can realize fast and efficient tightening operations, reduce operation time, and improve work efficiency.

[0015] As a further improvement of the above solution, an outer surface of the ratchet structure body is rotatably connected to an adjustment handle, and the outer surface of the adjustment handle is provided with a rubber anti-slip layer.

[0016] Through the above technical solution, the adjustment handle and the ratchet structure body are usually rotationally connected through a connection method such as an axis or a pin. This connection method allows the rotational movement of the handle to be directly transmitted to the ratchet structure. The ratchet structure body contains components such as a ratchet and a pawl. When the adjustment handle rotates, the pawl will push the ratchet to rotate, thereby driving the entire ratchet structure body to rotate. The rotation of the ratchet structure body will cause the webbing inside the tensioner to retract and release, thereby adjusting the tension of the tensioner. The ratchet structure has a one-way locking function, that is, the pawl can only allow the ratchet to rotate in one direction. In this way, during the tensioning process, even if the operator stops rotating the handle, the ratchet structure will maintain the current position to prevent the tensioner from loosening.

[0017] As a further improvement of the above solution, a release knob is provided on the surface of the housing.

[0018] Through the above technical solution, when the operator rotates the release knob, the internal unlocking mechanism is triggered, and the unlocking mechanism temporarily releases the one-way locking state of the ratchet structure body, so that the operator can easily release the tension. At this time, the webbing inside the tensioner can move freely, thereby quickly reducing the tension and ensuring that the tensioner can work normally when used again.

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

[0020] The utility model provides a fixed shaft, a limit plate and a fastening bolt, specifically, by rotating the limit plate, so that the limit plate rotates one end of the hook, and then the fastening bolt is threadedly connected with the inner wall of the limit plate to fix it, so as to shield the front end of the hook and avoid loosening during connection, thereby improving the stability of the hook during connection.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0029] Example:

[0030] Please combine Figure 1-5A tensioner structure of this embodiment includes a shell 1, a stretching column 2 is arranged on the inner wall of the shell 1, a supporting plate 3 is fixedly connected to the lower surface of the shell 1, a webbing 4 is arranged on the outer surface of the stretching column 2, a fixed shaft 11 is rotatably connected to the inner wall of the hook 5, a limiting plate 12 is fixedly connected to both ends of the fixed shaft 11, a fastening bolt 13 is threadedly connected to the inner wall of the limiting plate 12, one end of the fastening bolt 13 passes through the hook 5, and the main function of the stretching column 2 is to guide and support the webbing 4. When the webbing 4 passes through the stretching column 2 and is stretched during the tightening process, The column 2 can ensure the stability of the path of the webbing 4 and prevent the webbing 4 from being offset or twisted during the tightening process. By fixing the webbing 4 on the outer surface of the stretching column 2, the stress generated by the webbing 4 when tightened can be more evenly distributed on the stretching column 2, which can avoid stress concentration and reduce the risk of damage to the webbing 4 due to excessive local stress. The support plate 3 is fixed to the lower surface of the shell 1, and is mainly used to support and stabilize the stretching column 2. The presence of the support plate 3 can enhance the rigidity of the stretching column 2 and prevent it from bending or deforming during the tightening process.

[0031] There are two webbings 4, which are respectively arranged on both sides of the outer surface of the shell 1. The two webbings 4 are respectively arranged on both sides of the shell 1 to form a symmetrical structure. This design can ensure that the tensioner is evenly stressed during the tightening process, avoiding deflection or imbalance caused by unilateral force. The double webbing 4 design allows the operator to tighten and release more conveniently. The operator can pull the two webbings 4 at the same time, or operate one of the webbings 4 separately as needed, thereby achieving more flexible control.

[0032] The number of hooks 5 corresponds to the number of webbings 4. The design of the hooks 5 enables the webbings 4 to be quickly and conveniently connected to the object to be fixed. The operator only needs to hang the hooks 5 on the fixed points to complete the connection. No complicated operations or tools are required, which greatly simplifies the operation steps. The design of the hooks 5 enables the tensioner to be applicable to a variety of different fixed points. No matter whether it is a round, square or other shaped fixed point, as long as the hooks 5 can be hung, the tensioner can be used, which increases the versatility and scope of application of the tensioner, enabling it to play a role in more application scenarios.

[0033] The surface of the housing 1 is fixedly connected with a baffle 6, and a spring sheet 7 is arranged inside the baffle 6. When the webbing 4 is pulled out, the spring sheet 7 will be stretched to store energy. The operator can stretch the spring sheet 7 appropriately as needed to adjust the tension of the tensioner. When the webbing 4 is released, the spring sheet 7 will rebound quickly to release the stored energy, thereby providing a stable tension. This fast rebound feature ensures that the tensioner can always maintain a stable tension during use, and there will be no force fluctuations due to repeated stretching and release.

[0034] The inside of the shell 1 is fixedly connected with a ratchet structure body 8, and the ratchet structure has a one-way locking function, allowing the webbing 4 to move only in one direction, which means that during the tensioning process, the ratchet structure can prevent the webbing 4 from sliding in the opposite direction, ensuring that the tensioner will not loosen after tensioning and maintain a stable tensioning state, and the ratchet structure body 8 can realize fast and efficient tensioning operation, the operator only needs to pull the webbing 4 repeatedly, and the ratchet structure will continuously lock the webbing 4, thereby realizing fast tensioning. This method is more efficient than the traditional manual tensioning method, reduces the operation time, and improves work efficiency.

[0035] The outer surface of the ratchet structure body 8 is rotatably connected to an adjusting handle 9, and the outer surface of the adjusting handle 9 is provided with a rubber anti-slip layer. The adjusting handle 9 and the ratchet structure body 8 are usually rotatably connected by a connection method such as an axis or a pin. This connection method allows the rotational movement of the handle to be directly transmitted to the ratchet structure. The ratchet structure body 8 contains components such as a ratchet and a pawl. When the adjusting handle 9 rotates, the pawl will push the ratchet to rotate, thereby driving the entire ratchet structure body 8 to rotate. The rotation of the ratchet structure body 8 will cause the webbing 4 inside the tensioner to retract and release, thereby adjusting the tension of the tensioner. The ratchet structure has a one-way locking function, that is, the pawl can only allow the ratchet to rotate in one direction. In this way, during the tensioning process, even if the operator stops rotating the handle, the ratchet structure will maintain the current position to prevent the tensioner from loosening.

[0036] A release knob 10 is provided on the surface of the shell 1. When the operator rotates the release knob 10, the internal unlocking mechanism is triggered. The unlocking mechanism will temporarily release the one-way locking state of the ratchet structure body 8, and the operator can easily release the tension. At this time, the webbing 4 inside the tensioner can move freely, thereby quickly reducing the tension and ensuring that the tensioner can work normally when used again.

[0037] The implementation principle of a tensioner structure in the embodiment of the present application is as follows: the personnel first places the outer shell 1 of the tensioner near the object to be fixed, ensures that the supporting plate 3 is firmly in contact with the ground or other supporting surface, provides a stable supporting environment for the stretching column 2, and connects one end of the two webbings 4 with hooks 5 to the corresponding fixing points of the object to be fixed. The design of the hook 5 allows quick and convenient connection to fixing points of various shapes, and then rotates the limit plate 12 to rotate one end of the hook 5 of the limit plate 12, and then fixes it with the inner wall thread connection of the limit plate 12 by tightening the bolt 13, and blocks the front end of the hook 5 to avoid looseness during connection. As needed, the operator can pre-adjust the tensioning force by stretching the spring sheet 7 inside the baffle 6. The spring sheet 7 stores energy when stretched, providing a stable force source for the subsequent tensioning process. The operator rotates the adjustment handle 9 Since the adjusting handle 9 is rotatably connected to the outer surface of the ratchet structure body 8, the rotational movement of the handle is transmitted to the ratchet structure, so that the pawl inside the ratchet structure pushes the ratchet to rotate. The one-way locking function of the ratchet structure body 8 ensures that the webbing 4 can only move in one direction, preventing the webbing 4 from sliding in the opposite direction during the tensioning process, and ensuring the stability of the tensioner after tensioning. The operator repeatedly rotates the adjusting handle 9, and the ratchet structure continuously locks the webbing 4 to achieve fast and efficient tensioning operation. This method is more efficient than the traditional manual tensioning method, reduces operation time, and improves work efficiency. When the tension needs to be released, the operator rotates the release knob 10 on the surface of the shell 1 to trigger the internal unlocking mechanism. The unlocking mechanism temporarily releases the one-way locking state of the ratchet structure, allowing the webbing 4 to move freely and quickly reduce the tension. After releasing the tension, the tensioner can repeat the above steps to adapt to new fixing requirements.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
