Description

Technical Field

[0001] This utility model relates to the field of tarpaulin fastening technology, and in particular to a tarpaulin windproof fastening mechanism. Background Technology

[0002] In the field of freight transportation, especially in modes of transport such as road and rail, tarpaulins are widely used as an important protective covering for goods. They can effectively shield goods from wind, rain, and dust, preventing damage and contamination, and ensuring the integrity and safety of goods during transportation. They are an indispensable component of the protective measures in freight transportation.

[0003] Most commercially available tarpaulin fastening devices employ simple rope binding or buckle securing methods. However, these devices present several problems in practical use: Firstly, rope binding makes it difficult to precisely control the tightness of the tarpaulin. During transport in windy conditions, the tarpaulin is prone to loosening and lifting due to uneven stress, failing to provide reliable wind protection for the goods and posing a risk of damage. Secondly, both rope binding and buckle securing are cumbersome processes, requiring operators to spend considerable time repeatedly adjusting and securing the tarpaulin. Releasing the fasteners also requires significant effort, resulting in low work efficiency and increased labor costs. Therefore, this application proposes a tarpaulin windproof fastening mechanism to address these technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a windproof and fastening mechanism for tarpaulins. This mechanism uses a winding roller to retract the traction rope and tighten the tarpaulin. A limiting shell, limiting protrusions, and limiting wheels work together to restrict the rotation of the winding roller. The threaded connection between the locking ring and the locking block further reinforces the limiting effect. This ensures the tarpaulin remains firmly secured, effectively preventing wind and loosening, and guaranteeing the safety of goods transportation. Furthermore, the limiting and releasing operations are simple; the rope can be released by spring reset, quickly completing the tarpaulin tightening and loosening operations, improving work efficiency, and saving time and labor costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A tarpaulin windproof fastening mechanism includes a housing, a winding roller rotatably connected to the inner wall of the housing, a limit wheel fixedly connected to one end of the winding roller, a sliding rod fixedly connected to one side of the housing, the outer wall of the sliding rod being connected to the limit wheel via a limiting component for limiting the limit wheel, a guide tube fixedly connected to the top side of the housing, a traction rope provided on the outer wall of the winding roller, and a connector provided on the bottom side of the housing for connecting to a vehicle.

[0006] Furthermore, the limiting assembly includes a limiting shell slidably connected to the outer wall of the slide rod, the inner wall of the limiting shell is provided with a limiting protrusion, the limiting protrusion is provided on the outer wall of the limiting wheel, the outer wall of the slide rod is provided with a spring, and the outer wall of the limiting shell is provided with a locking assembly.

[0007] Furthermore, one end of the spring facing the limiting shell is connected to the limiting shell, and the other end of the spring is connected to the outer wall of the shell.

[0008] Furthermore, the locking assembly includes a locking block fixedly connected to the outer wall of the limiting shell, and the outer walls of two adjacent locking blocks are provided with locking rings, and the inner walls of the locking rings and the outer walls of the locking blocks are both provided with threads.

[0009] Furthermore, the connector includes a connecting shaft fixedly connected to the bottom side of the housing, and the bottom end of the connecting shaft is provided with two connecting rings, which are connected to each other by bolts.

[0010] Furthermore, a handle is fixedly connected to the other end of the winding roller to control the rotation of the winding roller, and an anti-drop plate is fixedly connected to one end of the handle to prevent the hand from slipping out when rotating the handle.

[0011] Furthermore, the traction rope is disposed on the inner wall of the guide tube to limit the movement of the traction rope.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the tarpaulin is tightened by retracting the traction rope through the winding roller, and the rotation of the winding roller is restricted by the cooperation of the limiting shell, the limiting protrusion and the limiting wheel. The limiting effect is further reinforced by the threaded connection of the locking ring and the locking block. The tarpaulin can be firmly tightened and kept in a tight state, effectively preventing the tarpaulin from loosening or lifting due to wind, thereby improving the windproof performance of the tarpaulin and ensuring the safety and reliability of goods during transportation.

[0013] 2. In this utility model, the operation of limiting and releasing the limit is simple. It can be completed by simply moving the limiting shell and tightening or loosening the locking ring. When releasing the limit, the traction rope can be released by relying on the spring reset. Operators can quickly complete the tightening and loosening of the tarpaulin, which greatly improves work efficiency and saves time and labor costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 2-4 This utility model provides an embodiment of a tarpaulin windproof fastening mechanism, comprising a housing 1, a winding roller 12 rotatably connected to the inner wall of the housing 1, a limiting wheel 13 fixedly connected to one end of the winding roller 12, a sliding rod 7 fixedly connected to one side of the housing 1, a limiting shell 8 slidably connected to the outer wall of the sliding rod 7, a limiting protrusion provided on the inner wall of the limiting shell 8, the limiting protrusion being provided on the outer wall of the limiting wheel 13, a spring 11 provided on the outer wall of the sliding rod 7, a locking block 9 fixedly connected to the outer wall of the limiting shell 8, a locking ring 10 provided on the outer wall of two adjacent locking blocks 9, both the inner wall of the locking ring 10 and the outer wall of the locking block 9 being threaded for limiting the limiting wheel 13, a guide tube 3 fixedly connected to the top side of the housing 1, a traction rope 4 provided on the outer wall of the winding roller 12, a connecting shaft 5 fixedly connected to the bottom side of the housing 1, two connecting rings 6 provided at the bottom end of the connecting shaft 5, the two connecting rings 6 being connected by bolts for connecting to a vehicle; Specifically, firstly, the housing 1 is installed onto the corresponding fixed position on the vehicle via two connecting rings 6 on its bottom connecting shaft 5. Bolts are passed through the connecting rings 6 and tightened to ensure the housing 1 is securely fixed to the vehicle. Next, the operator rotates the throttle 2, driving the winding roller 12 to rotate on the inner wall of the housing 1, causing the traction rope 4 wound on the outer wall of the winding roller 12 to be guided and released through the guide tube 3. One end of the traction rope 4 is connected to the tarpaulin, and then the throttle 2 is rotated in the opposite direction, causing the winding roller 12 to rotate in the opposite direction, thereby retracting the traction rope 4 and using its tension to tighten the tarpaulin, completing the initial tightening. Afterwards, by sliding the limiting shell 8 along the slide rod 7, the limiting protrusion on the inner wall of the limiting shell 8 is embedded into the outer wall of the limiting wheel 13, thereby restricting the rotation of the winding roller 12. Next, the locking ring 10 is fitted onto the adjacent locking block 9 and tightened through the threaded connection between the inner wall of the locking ring 10 and the outer wall of the locking block 9, further reinforcing the limiting effect, preventing the limiting shell 8 from sliding, ensuring the winding roller 12 is firmly limited, and keeping the tarpaulin in a taut state, thereby achieving the windproof and secure function. When it is necessary to release the limit, simply rotate the locking ring 10 so that it is no longer fitted onto the adjacent locking block 9. At this time, the compressed spring 11 returns to its original position, pushing the limiting shell 8 to slide along the slide rod 7, so that the limiting protrusion on the inner wall of the limiting shell 8 no longer contacts the limiting wheel 13, thereby releasing the limit on the winding roller 12 and realizing the release operation of the traction rope 4.

[0018] Reference Figures 1-3 One end of the spring 11 facing the limiting shell 8 is connected to the limiting shell 8, and the other end of the spring 11 is connected to the outer wall of the shell 1. The other end of the winding roller 12 is fixedly connected to the handle 2 for controlling the rotation of the winding roller 12. One end of the handle 2 is fixedly connected to the anti-disengagement plate for preventing the hand from slipping when rotating the handle 2. The traction rope 4 is set on the inner wall of the guide tube 3 for limiting the traction rope 4. Specifically, one end of the spring 11 is connected to the limiting shell 8, and the other end is connected to the outer wall of the shell 1. This connection allows the spring 11 to provide elastic restoring force when the limiting shell 8 slides. The winding roller 12 is rotated via a handle 2 fixedly connected to its other end. The operator can drive the winding roller 12 to rotate forward or backward by turning the handle 2, thereby releasing or retracting the traction rope 4. The traction rope 4 is set in the inner wall of the guide tube 3. Guided by the guide tube 3, it ensures that the traction rope 4 can be smoothly released or retracted from the winding roller 12 and accurately connected or tightened to the tarpaulin.

[0019] Working principle: The housing 1 is securely installed on the vehicle by using two connecting rings 6 on the bottom connecting shaft 5, fitted onto the corresponding fixed positions on the vehicle, and tightening bolts through the connecting rings 6. Then, the operator rotates the handle 2, causing the winding roller 12 to rotate on the inner wall of the housing 1. This allows the traction rope 4, wound on the outer wall of the winding roller 12, to be released through the guide tube 3, connecting one end of the traction rope 4 to the tarpaulin. Then, rotating the handle 2 in the opposite direction causes the winding roller 12 to rotate in the opposite direction, retracting the traction rope 4 and tightening the tarpaulin using tension to complete the initial fastening. Finally, by moving the limiting shell 8 along the slide rod 7, the limiting shell 8... The limiting protrusion on the inner wall is embedded in the outer wall of the limiting wheel 13 to restrict the rotation of the winding roller 12. Then, the locking ring 10 is put on the adjacent locking block 9 and tightened through the threaded connection between the inner wall of the locking ring 10 and the outer wall of the locking block 9 to strengthen the limiting effect, prevent the limiting shell 8 from sliding, ensure that the winding roller 12 is firmly limited, keep the tarpaulin in a tight state, and achieve the windproof and fastening function. When releasing the limiting, simply rotate the locking ring 10 so that it is no longer put on the adjacent locking block 9. Finally, the compressed spring 11 resets the limiting protrusion on the inner wall of the limiting shell 8 and the limiting wheel 13, so that the traction rope 4 can be released.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
