Abstract
Description
Technical Field
[0001] This utility model relates to the field of strap technology, and in particular to a portable and simple strapping device. Background Technology
[0002] In the existing technology, strapping devices are widely used in various scenarios, such as backpack shoulder strap adjustment and cargo fixing. Different specifications and structures of straps are required for different scenario needs.
[0003] Currently, there are generally two types of straps: one type has a more complex structure and can be adapted to higher-intensity applications, such as trailers and other high-strength environments; the other type has a simpler structure and can be used in daily life. However, due to the simple structure of the straps, they are inconvenient to adjust and require multiple attempts to achieve the ideal length, especially when operating with one hand. The tightening effect is not ideal, and they are easily loosened by external forces, failing to achieve the expected results. Their applicability is very limited, so there is a need for improvement. Utility Model Content
[0004] This utility model provides a portable and simple strapping device that is easy to adjust, can be operated with one hand and tightened in one go without repeated adjustments, is reliable in use, effectively restricts tension through its structure, ensures the stability of the strap, is easy to process and manufacture, and has a wide range of applications. It solves the technical problems of existing technologies where complex straps are large in size and have overly complicated structures, making them inconvenient for daily use, while simple straps have overly simple structures, are inconvenient to adjust, have unsatisfactory tightening effects, and have a more limited range of applications.
[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a portable and simple strapping device includes a shell, a first strap of fixed length on the rear side of the shell, and a second strap with an adjustable exposed length on the front side of the shell. A limiting structure for adjusting and limiting the exposed length of the second strap is provided on the front side of the shell. The limiting structure includes a baffle fixed to the front side of the shell and a clamping plate rotatably installed in the middle of the shell. The clamping force of the clamping plate and the baffle limits and adjusts the second strap. The lengths of the first and second straps can be adjusted according to actual needs to meet general requirements. A buckle or hanging ring structure is installed at the tail end of the first strap and the bottom end of the second strap to fix the buckle or hanging ring to two objects. The limiting structure can adjust and limit the exposed length of both ends of the second strap, thereby adjusting the tension of the two items. This strapping device can be used for everyday situations such as dragging items or tightening and fixing items when a car trunk cannot be properly closed. The device is also small in size, making it easy to carry and store.
[0006] Preferably, one end of the second strap extends from the front end of the outer shell, and the other end of the second strap passes through the gap between the baffle and the clamp and then emerges from the bottom of the outer shell. A corresponding groove is provided at the bottom of the outer shell, and the distance between the bottom end of the second strap and the first strap can be adjusted by the limiting structure.
[0007] Preferably, the clamping plate is rotatably mounted inside the outer casing via a pivot. A torsion spring is located in the middle of the pivot, with its two ends abutting against the bottom surface of the clamping plate and the bottom surface of the outer casing, respectively. In its natural state, the clamping plate is clamped to the surface of the second strap under the action of the torsion spring. When the front end of the second strap is pulled, due to insufficient clamping force, it can be pulled out continuously, shortening the distance between the two buckles and further shortening the distance between the two items. When the bottom end of the second strap is pulled, the clamping force of the clamping plate increases. The harder it is pulled, the greater the clamping force becomes, which can limit the reverse sliding of the second strap.
[0008] Preferably, the bottom surface of the clamping plate and the bottom surface of the outer shell are provided with slots corresponding to the torsion spring. The slots on the bottom surface of the clamping plate and the bottom surface of the outer shell, corresponding to the two ends of the torsion spring, facilitate proper installation.
[0009] Preferably, the side of the baffle that mates with the clamp is integrally formed with an uneven anti-slip texture. The anti-slip texture is an uneven, wavy or continuous "Z"-shaped bevel structure, which can increase the friction between the baffle and the second strap when it mates with the clamp.
[0010] Preferably, the end face where the clamping plate and the baffle mate has several conical protrusions integrally formed. These protrusions, along with the anti-slip texture on the baffle surface and the knitted texture on the second strap surface, limit the movement of the second strap. When taut, the second strap cannot slide in the reverse direction. If the bottom end of the second strap is pulled, the clamping force increases with the combined action of the protrusions on the clamping plate surface, the anti-slip texture on the baffle surface, the knitted texture on the second strap surface, and the torsion spring, ensuring overall tension and preventing reverse slippage. Only by manually pressing the end of the clamping plate to detach it from the surface of the second strap can the tension between the first and second straps be relaxed, allowing the second strap to slide freely for disassembly.
[0011] Preferably, the outer shell, baffle, and clamp are all made of metal. The metal material of the outer shell, baffle, and clamp ensures overall strength and allows them to withstand higher tensile forces.
[0012] Preferably, both the end of the first strap and the bottom end of the second strap are provided with buckles of different specifications. Buckles or hanging loops can be installed on the tail end of the first strap and the bottom end of the second strap, respectively, for hanging on different objects.
[0013] Therefore, the portable and simple strapping device of this utility model has the following advantages: it is easy to adjust, can be operated with one hand and tightened in one go without repeated adjustment, is reliable in use, effectively restricts through structure, ensures the stability of the strap, is easy to process and manufacture, is smaller and lighter in size, is convenient for daily carrying and storage, and has a wide range of applications.

[0020] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0021] Example: like Figure 1 and 2 As shown in Figures 3, 4, and 5, a portable simple strapping device includes a housing 1, a first strap 2 of fixed length fitted on the rear side of the housing 1, and a second strap 3 slidably fitted on the front side of the housing 1. Both the end of the first strap 2 and the bottom end of the second strap 3 are fitted with buckles 4 of different specifications.
[0022] The front side of the outer casing 1 is equipped with a limiting structure for adjusting and limiting the exposed length of the second strap 3.
[0023] The limiting structure includes a baffle 5 fixedly installed on the front side of the outer shell 1 and a clamping plate 6 rotatably installed in the middle of the outer shell 1. The baffle 5 is welded and fixed to the inner wall of the outer shell 1.
[0024] One end of the second strap 3 extends from the front end of the outer shell 1, and the other end of the second strap 3 passes through the gap between the baffle 5 and the clamp 6 and then emerges from the bottom of the outer shell 1. The bottom of the outer shell 1 has a corresponding groove, and the length of the two ends of the second strap 3 exposed can be adjusted by the clamping force of the clamp 6 and the baffle 5.
[0025] The outer shell 1, baffle 5, and clamp 6 are all made of metal.
[0026] The clamping plate 6 is rotatably mounted in the middle of the outer shell 1 via a rotating shaft. The rotating shaft is fixedly mounted on the inner wall of the outer shell 1, and the clamping plate 6 rotates around the rotating shaft. A torsion spring 7 is sleeved and installed in the middle of the rotating shaft.
[0027] The two ends of the torsion spring 7 abut against the bottom surface of the clamping plate 6 and the bottom surface of the outer shell 1, respectively. The bottom surface of the clamping plate 6 and the bottom surface of the outer shell 1 are provided with slots corresponding to the torsion spring 7.
[0028] The side of the baffle 5 that mates with the clamp 6 has an integrally formed anti-slip texture 8; the end face of the clamp 6 that mates with the baffle 5 has an integrally formed several conical protrusions 9. The protrusions 9, together with the anti-slip texture 8 on the surface of the baffle 5 and the knitted texture on the surface of the second strap 3, complete the limiting of the second strap 3.
[0029] In its natural state, the clamping plate 6 is clamped to the surface of the second strap 3 under the action of the torsion spring 7. When in use, the buckle 4 at the end of the first strap 2 and the buckle 4 at the bottom of the second strap 3 are respectively fixed to the two items. At this time, the device is in a vertical or horizontal position. When the front end of the second strap 3 is pulled, it can be pulled out continuously due to insufficient clamping force, shortening the distance between the two buckles 4, and further shortening the distance between the two items.
[0030] When taut, the second strap 3 cannot slide in the reverse direction. If the bottom end of the second strap 3 is pulled, the clamping force increases with the combined action of the protrusions 9 on the surface of the clamping plate 6, the anti-slip texture 8 on the surface of the baffle 5, the knitted texture on the surface of the second strap 3, and the torsion spring 7. This ensures the overall tension and prevents slippage in the reverse direction. Only by manually pressing the end of the clamping plate 6 to detach it from the surface of the second strap 3 can the tension of the first strap 2 and the second strap 3 be relaxed, allowing the second strap 3 to slide freely for disassembly.
[0031] The strapping device of this utility model can be used for everyday situations such as dragging items or tightening and securing car trunks when they cannot be properly fastened. The device is also small in size, making it easy to carry and store.
