Description
Technical Field
[0001] The utility model relates to the technical field of mechanical engineering, in particular to a tensioner with a locking structure. Background Art
[0002] In traditional tensioner designs, there is usually a ratchet mechanism to fix the tension of the rope or belt during the tensioning process to prevent it from retracting. However, this ratchet mechanism may sometimes rotate accidentally due to improper operation or external interference, causing the tensioner to loosen, which may cause serious safety hazards in certain high-risk working environments.
[0003] Therefore, the market is in urgent need of a new tensioner design that can provide a more reliable locking mechanism without sacrificing operational convenience. This design should be able to effectively prevent unexpected rotation of the ratchet mechanism while simplifying the operating process so that operators can quickly and accurately complete the locking operation even without professional training. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a tensioner with a locking structure.
[0005] The utility model is implemented by the following technical scheme: a tensioner with a locking structure, comprising a side frame, an assembly cover is fixedly connected to the outer surface of the side frame, a receiving column is arranged inside the assembly cover, a ratchet body is arranged on the outer surface of the receiving column, a mounting block is welded to the top end of the side frame, a sliding groove is arranged inside the side frame, a locking tooth is slidably connected to the inside of the sliding groove, a limiting hole is arranged on the top end of the locking tooth, a limiting frame is welded to the front face of the mounting block, connecting plates are welded to the front and rear ends of the mounting block, and the internal thread of the connecting plate is connected to the limiting bolt.
[0006] Through the above technical solution, through the design of the assembly cover, when the ratchet body needs to be repaired or maintained, it can be convenient for personnel to disassemble and access and maintain the internal components. The use of the ratchet body makes the tightening process more efficient. The user can quickly achieve the required tension by turning the ratchet. At the same time, the locking structure ensures that once the required tension is reached, it will not be accidentally loosened.
[0007] As a further improvement of the above solution, there are two assembly covers, which are fixedly connected to two sides of the outer surface of the side frame respectively.
[0008] Through the above technical solution, the assembly cover symmetrical on both sides can provide better structural balance, which helps to disperse and reduce deformation or damage that may be caused by unilateral force.
[0009] As a further improvement of the above solution, a locking groove is provided on the surface of the side frame.
[0010] Through the above technical solution, the design of the locking groove is the key to realizing the locking function of the tensioner. Through cooperation with other matching parts, the tensioner can be fixed in the current position after the required tension is reached to prevent accidental loosening. The design of the locking groove enables the user to only operate the ratchet body to the appropriate position during use, and then complete the locking through a simple snap-on action, which simplifies the operating steps and improves work efficiency.
[0011] As a further improvement of the above solution, an operating handle is provided inside the side frame, and an anti-slip pad is provided on the outer surface of the operating handle.
[0012] Through the above technical solution, the anti-slip pad can increase the friction between the hand and the operating handle, making it easier for the user to hold it firmly during operation and reducing the risk of slipping. The anti-slip pad is usually made of soft material, which can reduce the fatigue of the hand when holding it for a long time and improve the comfort of operation.
[0013] As a further improvement of the above solution, an extension block is fixedly connected to the surface of the operating handle.
[0014] Through the above technical solution and the design of the extension block, the user can operate at a position far away from the ratchet body, which increases the convenience and safety of the operation.
[0015] As a further improvement of the above solution, a positioning block is fixedly connected to the surface of the extension block, and the positioning block is slidably connected to the inside of the locking groove.
[0016] Through the above technical scheme, the personnel stretch the extension block through the operating handle, and the movement of the extension block drives the positioning block to slide inside the locking groove. When the positioning block slides to the sidemost side of the locking groove, the positioning block can be stuck on the surface of the ratchet body, which can effectively limit the rotation of the ratchet body, thereby realizing the locking function and ensuring that the tensioner will not accidentally loosen during use. The locking effect of the positioning block can prevent the ratchet body from rotating due to improper operation or external interference during use, thereby improving the safety of operation. Through the design of the positioning block, the user only needs to slide the positioning block into the locking groove and get it stuck on the surface of the ratchet body to complete the locking, which simplifies the operating steps and improves work efficiency. Through mechanical locking, the positioning block can more reliably fix the position of the ratchet body. Compared with relying solely on friction or other methods to maintain a fixed state, it can better ensure the reliable operation of the equipment under various working conditions.
[0017] As a further improvement of the above solution, a reinforcement seat is fixedly connected to the outer surface of the side frame.
[0018] Through the above technical solution, the reinforcement seat can enhance the structural strength of the side frame to prevent deformation or breakage caused by external force or long-term use, and through the design of the reinforcement seat, the stability of the entire device can be improved, especially when the device is subjected to impact or vibration, it can effectively reduce damage to the side frame.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] The utility model provides a positioning block. The operator first stretches the extension block by operating the handle. The movement of the extension block drives the positioning block to slide inside the locking groove. When the positioning block slides to the sidemost edge of the locking groove, the positioning block can be stuck on the surface of the ratchet body, effectively limiting the rotation of the ratchet body, thereby realizing the locking function, ensuring that the tensioner will not be accidentally loosened during use, and preventing the ratchet body from rotating due to improper operation or external interference during use, thereby improving the safety of operation. Moreover, the operator only needs to slide the positioning block into the locking groove and get it stuck on the surface of the ratchet body to complete the locking, which simplifies the operating steps and improves work efficiency.
[0021] When the ratchet body of the device needs to be limited, the locking tooth is slid from the front end position of the inside of the limit frame by rotating the limit bolt inside the connecting plate. When the receiving column slides at the front end position inside the mounting block, the locking tooth is slid into the groove of the ratchet body. When the locking tooth does not need to lock the ratchet body, the locking tooth is slid to the bottom end close to the limit bolt. The locking tooth is limited by rotating the limit bolt to extend to the inside of the limit hole opened at the top of the locking tooth. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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.
[0030] Example:
[0031] Please combine Figure 1-5 A tensioner with a locking structure in this embodiment includes a side frame 1, an assembly cover 2 is fixedly connected to the outer surface of the side frame 1, a receiving column 3 is arranged inside the assembly cover 2, a ratchet body 4 is arranged on the outer surface of the receiving column 3, a mounting block 10 is welded to the top of the side frame 1, a sliding groove 11 is provided inside the side frame 1, a locking tooth 13 is slidably connected inside the sliding groove 11, a limiting hole 14 is provided at the top of the locking tooth 13, a limiting frame 12 is welded to the front of the mounting block 10, and connecting plates 15 are welded to the front and rear ends of the mounting block 10. The internal thread connection of the connecting plate 15 is connected to the limit bolt 16, and the design of the assembly cover 2 allows the user to easily disassemble and install, so that when the ratchet body 4 needs to be repaired or maintained, the internal components can be quickly accessed, which simplifies the maintenance process and improves maintenance efficiency. The ratchet body 4 is a common mechanical structure. By rotating the ratchet, the user can quickly achieve the required tension. The use of the ratchet body 4 makes the tightening process more efficient and can provide a stable tensioning force during the rotation process. The locking structure ensures that once the required tension is reached, the ratchet body 4 will not be accidentally loosened.
[0032] There are two assembly covers 2, which are fixedly connected to the two sides of the outer surface of the side frame 1 respectively. The symmetrical assembly cover 2 design can provide better structural balance. Since the two assembly covers 2 are respectively located on the two sides of the side frame 1, they can evenly distribute and withstand the forces from both sides, thereby reducing the imbalance phenomenon that may be caused by unilateral force.
[0033] A locking groove 5 is provided on the surface of the side frame 1. The locking groove 5 has a positioning function, which can ensure that the ratchet body 4 is fixed at a specific position to prevent the position of the ratchet body 4 from changing due to external force during use.
[0034] An operating handle 6 is provided inside the side frame 1, and an anti-slip pad is provided on the outer surface of the operating handle 6. The anti-slip pad can increase the friction between the hand and the operating handle 6, making it easier for the user to hold it firmly during operation and reduce the risk of slipping. The anti-slip pad is usually made of soft material, which can reduce the fatigue of the hand when holding it for a long time and improve the comfort of operation.
[0035] An extension block 7 is fixedly connected to the surface of the operating handle 6. Through the design of the extension block 7, the user can operate at a position far away from the ratchet body 4, which increases the convenience and safety of the operation.
[0036] A positioning block 8 is fixedly connected to the surface of the extension block 7, and the positioning block 8 is slidably connected to the inside of the locking groove 5. When the positioning block 8 slides to the sidemost edge of the locking groove 5, it can be stuck on the surface of the ratchet body 4, thereby effectively limiting the rotation of the ratchet body 4 and realizing the locking function. This design ensures that the tensioner will not be accidentally loosened during use. The locking effect of the positioning block 8 can effectively prevent the ratchet body 4 from rotating due to improper operation or external interference during use, thereby greatly improving the safety of operation. In addition, the design of the positioning block 8 also simplifies the operating steps. The user only needs to slide the positioning block 8 into the locking groove 5 and get it stuck on the surface of the ratchet body 4 to complete the locking. This It not only improves the work efficiency, but also ensures the reliable operation of the equipment under various working conditions. When the ratchet body 4 of the equipment needs to be limited, the locking tooth 13 is slid from the inside of the limit frame 12 to the front end position by rotating the limit bolt 16 inside the connecting plate 15. When the receiving column 3 slides to the front end position inside the mounting block 10, the locking tooth 13 is slid into the groove of the ratchet body 4. When the locking tooth 13 does not need to lock the ratchet body 4, the locking tooth 13 is slid to the bottom end close to the limit bolt 16. The locking tooth 13 is limited by rotating the limit bolt 16 to extend to the inside of the limit hole 14 opened at the top of the locking tooth 13.
[0037] The outer surface of the side frame 1 is fixedly connected with a reinforcement seat 9, which can enhance the structural strength of the side frame 1 to prevent deformation or breakage caused by external force or long-term use. The design of the reinforcement seat 9 can improve the stability of the entire device, especially when the device is subjected to impact or vibration, and can effectively reduce damage to the side frame 1.
[0038] The implementation principle of a tensioner with a locking structure in the embodiment of the present application is as follows: the user can access the ratchet body 4 by removing the assembly cover 2. Since there are two assembly covers 2 and they are symmetrically distributed on both sides of the side frame 1, this design provides a better structural balance and is convenient for users to perform maintenance and care. The user drives the ratchet body 4 by rotating the operating handle 6 to achieve the required tension. The use of the ratchet body 4 makes the tensioning process more efficient and can provide a stable tensioning force during the rotation process. When the required tension is reached, the user can slide the positioning block 8 to make it enter the locking groove 5 and get stuck on the surface of the ratchet body 4, thereby effectively limiting the rotation of the ratchet body 4 and achieving the locking function, which ensures that the tensioner will not accidentally loosen during use. The outer surface of the operating handle 6 is provided with an anti-slip pad, which increases the friction between the hand and the operating handle 6, reduces the risk of slipping, and improves the comfort of operation. The outer surface of the side frame 1 is fixedly connected with a reinforcement seat 9, which can enhance the structural strength of the side frame 1, prevent deformation or breakage caused by external force or long-term use, and improve the stability of the entire device.
[0039] 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.
