[0002] In modern industry and daily applications, the tensioner is a key component for adjusting the tension in the mechanical system, and its performance directly affects the stability and efficiency of the entire system. Traditionally, the tensioner designs on the market mostly adopt manual control mode. Although this design meets the basic use needs to a certain extent, its limitations gradually emerge in the face of complex and changing working environments, mainly reflected in the following aspects:

[0003] 1. Inefficiency: Manually controlled tensioners require operators to regularly check the tension status and manually adjust it as needed. This process is not only time-consuming, but also difficult to respond quickly in continuous operation or remote operation scenarios, affecting production efficiency.

[0031] Reference Figures 1 to 6An improved tensioner includes a control unit 10 and two sets of tension rods 40. A control shaft 20 is installed in the control unit 10. A first bevel gear 11 is installed on the control shaft 20. The first bevel gear 11 is meshed with a second bevel gear 12 on both sides. The tension rod 40 is assembled and connected with the second bevel gear 12. The tension rod 40 includes a sleeve 41. One end of the sleeve 41 is connected to the second bevel gear 12. The other end is threadedly connected with a screw 42. The exposed end of the screw 42 is equipped with a hook 43. The sleeve 41 is driven to rotate by the rotation of the bevel gear, and the rotation of the sleeve 41 causes the screw 42 to move along the axial direction.

[0032] The end of the screw rod 42 and the hook 43 are connected by a chain 44. This design allows the two ends of the tensioner to fit the surface of the cargo to avoid the tensioner being suspended in the air, further enhancing the stability and safety of the tensioning force. When the cargo is irregular in shape or requires force at a specific angle, the flexible hook 43 design connected by the chain 44 can ensure uniform force and prevent cargo displacement or damage, and is particularly suitable for bundling and fixing operations in complex loading environments.

[0033] The control shaft 20 includes a first shaft portion 21, a drive motor 22, and a second shaft portion 23, which are coaxially arranged. The output end of the drive motor 22 is connected to the second shaft portion 23, and the first shaft portion 21 is fixedly connected to the housing of the drive motor 22. The first shaft portion 21 is connected to a control handle 50, and a ratchet 52 is mounted on the first shaft portion 21. A pawl 51 is mounted on the control handle 50 through a rotating pin. When the control handle 50 is rotated, the pawl 51 buckles the ratchet 52 to drive the control shaft 20 to rotate. The second shaft portion 23 is connected to the first bevel gear 11.

[0034] The housing of the driving motor 22 is equipped with a clutch mechanism 30, and the clutch mechanism 30 is assembled and connected with the second shaft portion 23. The clutch mechanism 30 includes a fixed seat 31, a sleeve shaft portion 32 and a telescopic switch 37. The fixed seat 31 is provided with a fixed shaft portion, and a through hole for the second shaft portion 23 to pass through is provided in the fixed shaft portion. The sleeve shaft portion 32 is sleeved on the fixed shaft portion, and a plurality of limiting protrusions 33 are provided on the outer peripheral side of the fixed shaft portion. A limiting groove cooperating with the limiting protrusion 33 is provided on the inner wall of the sleeve shaft portion 32. The sleeve shaft portion 32 faces the second shaft portion 23. A first tooth portion 34 is provided on the end surface of the shaft portion 23, and a second tooth portion 35 corresponding to the first tooth portion 34 is provided on the second shaft portion 23. The telescopic switch 37 is connected to a control sleeve 36, and the control sleeve 36 is sleeved on the sleeve shaft portion 32. The clutch mechanism 30 has two states: connected and disconnected. In the connected state, the power of the housing of the rotating drive motor 22 is transmitted to the second shaft portion 23, and the housing of the drive motor 22 and the second shaft portion 23 rotate simultaneously as a whole; in the disconnected state, the power of the housing of the rotating drive motor 22 cannot be transmitted to the second shaft portion 23.

[0035] Utilizing the function of the above clutch, the present application has two control modes: manual control and electronic control:

[0036] When manual control is selected, the clutch mechanism 30 is in a connected state. At this time, the first shaft portion 21, the drive motor 22 and the second shaft portion 23 can be regarded as a whole. The user rotates the control shaft 20 through the control handle 50, and drives the tensioning rods 40 on both sides to rotate through the meshing connection between the first bevel gear 11 and the second bevel gear 12. The rotation directions of the sleeves 41 of the tensioning rods 40 on both sides are opposite. At this time, the threaded connection depth of the screw 42 and the sleeve 41 can be changed, thereby changing the overall length of the tensioner, so that the spacing between the hooks 43 at both ends of the tensioner is increased or decreased, thereby realizing the bundling or loosening of the goods.

[0037] When electronic control is selected, the clutch mechanism 30 is in a disconnected state, and the user starts the drive motor 22 , which drives the second shaft 23 to rotate, and through the meshing connection between the first bevel gear 11 and the second bevel gear 12 , drives the tension rods 40 on both sides to rotate.

[0038] In order to further improve the convenience of operation of the tensioner, an electric control system is provided on the control part 10, and the telescopic switch 37 is electrically connected to the electric control system. The electric control system includes a remote transmission unit, and the user can remotely control the tensioner to tighten or loosen, and the user can also monitor the tensioning state of the tensioner. The electric control system can also include a display control panel 13, and the display control panel 13 can display the working status of the equipment in real time, such as motor speed, working mode, battery power and other key information, and can also allow the user to intuitively adjust the setting parameters and perform refined operation control to meet personalized adjustments under different operation requirements and ensure operation efficiency and quality.

[0039] In addition, a connecting column 24 is provided at the end of the extension control portion 10 of the first shaft portion 21, and the connecting column 24 is used for external power tools. The setting of the connecting column 24 provides convenience for external power tools. This flexible design allows the tensioner to obtain support from additional power sources when necessary, thereby enhancing its continuous operation capability in long-term operations or high-load tasks, and also provides more diversified power solutions for on-site operations.
