Description

Technical Field

[0001] This utility model relates to the field of strap technology, and in particular to a tension strap device. Background Technology

[0002] In the existing technology, common elastic traction belts (such as elastic ropes and elastic bands) are usually composed of a single or a few elastic bands, with hooks at both ends for connecting two objects. Although they are convenient to use, their structure is relatively simple.

[0003] Current traction belts or tension belts have poor impact resistance. When two connected objects undergo sudden relative displacement, the huge tensile force will directly act on the elastic belt, which can easily cause the elastic belt to overload and break, posing a serious safety hazard. Furthermore, the strength of traditional elastic belts is determined by the material itself, and cannot be adjusted according to different usage scenarios. Either multiple specifications of elastic belts need to be prepared, otherwise it is difficult to adapt to different needs and meet higher practical requirements. Therefore, there is a need for improvement. Utility Model Content

[0004] This utility model provides a tension belt device that can absorb impact loads through a built-in buffer spring, effectively preventing the tension belt from breaking due to overload, thus improving safety. The device has high overall strength and long service life, and can be used in various occasions. It solves the technical problems of existing traction belts or tension belts, which have relatively simple structures, are prone to breakage due to overload, pose significant safety hazards, and are limited in application due to their own limitations, thus failing to meet higher practical needs.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a tension band device, comprising a tension component in the middle and a first elastic band and a second elastic band on both sides. The tension component includes a first pull tube and a second pull tube that can slide relative to each other. A buffer spring is provided between the first pull tube and the second pull tube. Hooks or locking rings are provided at the ends of the first elastic band and the second elastic band. In use, the locking rings at both ends of the first elastic band and the second elastic band are installed on two different objects, such as two electric vehicles or a trunk that cannot be closed tightly in time. This device is applicable to many occasions and is small in size, making it easy to carry or store. When tension is generated, the buffer spring is first subjected to force and absorbs it, reducing the possibility of the elastic band breaking due to sudden tension. If only the elastic band is connected without a tension component in the middle, the elastic band is easy to break when subjected to sudden tension. This utility model can achieve segmented tension through the buffer spring, ensuring that the first elastic band and the second elastic band are always within a safe force range. It is applicable to various occasions and is safe to use.

[0006] Preferably, both the first and second elastic bands are composed of several individual elastic bands stacked together to ensure strength. By stacking multiple individual elastic bands, the overall strength and load-bearing capacity of the device are improved, making it suitable for high-strength applications. This prevents a single elastic band from breaking due to excessive stretching, thus enhancing safety and durability.

[0007] Preferably, both the first and second elastic bands are fitted with metal retaining sleeves at their ends. The retaining sleeves serve two purposes: firstly, they fit over the sewn ends of the elastic bands to prevent breakage and ensure safety; secondly, they restrict the hooks from slipping.

[0008] Preferably, both the first and second pull cylinders have several mounting slots on their base plates. The first and second elastic bands pass through these mounting slots and are fitted onto the base plates of the first and second pull cylinders. The ends of the first and second elastic bands are sewn together to form a ring structure. The elastic bands are mounted on the base plates by wrapping around the corresponding mounting slots, achieving a ring structure, preventing slippage or displacement, ensuring strength, and facilitating assembly.

[0009] Preferably, an adjustment component is provided between the first pull tube and the second pull tube.

[0010] Preferably, the adjusting component includes an adjusting plate slidably installed inside the second pull tube, and the two ends of the buffer spring are respectively fixedly installed at the bottom of the first pull tube and on the surface of the adjusting plate. By sliding the adjusting plate, the compression of the buffer spring can be precisely controlled, thereby adjusting the elastic force; the structure is simple and intuitive, easy for users to operate, and allows for quick adjustment.

[0011] Preferably, the adjusting component further includes several elastic limiting blocks installed on the outside of the adjusting plate. Corresponding grooves are formed on the outer wall of the adjusting plate, and storage springs are installed within these grooves. The elastic limiting blocks and storage springs provide automatic locking and resetting functions, ensuring that the adjusting plate can be stably fixed after adjustment and preventing accidental slippage; thus improving the stability and reliability of the device during use.

[0012] Preferably, the adjusting component further includes several slots formed on the outer wall of the second pull tube, from which elastic limiting blocks can pop out for limiting. The slots and elastic limiting blocks work together to achieve multi-level adjustment, allowing users to select different fixed positions as needed and precisely control the elastic force. This design ensures that the device is suitable for different occasions, adapts to different distances, and meets different practical needs.

[0013] Preferably, the first pull tube, the second pull tube, the adjusting plate, and the elastic limiting block are all made of metal. The metal material gives the device higher mechanical strength, wear resistance, and corrosion resistance, ensuring it is not easily damaged under frequent use and high-pressure environments, significantly extending its service life, while also improving the overall quality and reliability of the product.

[0014] Therefore, the tension belt device of this utility model has the following advantages: it can absorb impact loads through the built-in buffer spring, effectively prevent the tension belt from breaking due to overload, improve safety, the device has high overall strength and long service life, can be used in different occasions, the device structure is relatively concentrated and the size is small, making it easy to carry or store.

[0021] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: like Figure 1 and 2 As shown in Figures 3, 4, and 5, a tension band device includes a cylindrical tension component in the middle and a first elastic band 1 and a second elastic band 2 at both ends; the first elastic band 1 and the second elastic band 2 are each composed of several independent elastic bands stacked together, and the two ends of the elastic bands are tightly sewn together and fixed.

[0023] Both ends of the first elastic band 1 and the second elastic band 2 are equipped with hooks 3 or locking ring structures; both ends of the first elastic band 1 and the second elastic band 2 are also fitted with metal limiting sleeves 4, which are fitted at the end of the first elastic band 1 and the second elastic band 2 and are locked in place by plastic coating or deformation.

[0024] The tension assembly includes a first pull cylinder 5 and a second pull cylinder 6 that can slide relative to each other. Several independent mounting grooves 7 are provided on the bottom plates of the first pull cylinder 5 and the second pull cylinder 6. The first elastic band 1 and the second elastic band 2 pass through the mounting grooves 7 and are fitted onto the bottom plates of the first pull cylinder 5 and the second pull cylinder 6. The first elastic band 1 and the second elastic band 2 are sewn together at both ends to form a ring structure.

[0025] An adjusting component is installed between the first pull tube 5 and the second pull tube 6; the adjusting component includes an adjusting plate 8 that is slidably installed inside the second pull tube 6, and a buffer spring 11 is installed between the adjusting plate 8 and the bottom plate of the first pull tube 5.

[0026] The outer side of the adjusting plate 8 is slidably mounted with 2 and elastic limit block 9. The outer wall of the adjusting plate 8 is provided with a corresponding groove, and a storage spring is installed in the groove.

[0027] The adjusting component also includes several sets of slots 10 formed on the outer wall of the second pull tube 6, and the elastic limiting block 9 can pop out from the slot 10 to limit the movement.

[0028] The first pull tube 5, the second pull tube 6, the adjusting plate 8, and the elastic limit block 9 are all made of steel metal.

[0029] In use, the locking rings at both ends of the first elastic band 1 and the second elastic band 2 are installed on two different objects, such as two electric vehicles or a trunk that cannot be closed tightly in time. The elastic limit block 9 can be manually pressed to retract it. Pushing or pulling the first pull tube 5 will drive the adjusting plate 8 to slide. When it slides to the position of the slot 10, the limit block pops out under the action of the storage spring and locks into the slot 10, thereby fixing the adjusting plate 8 in that position. This realizes the adjustment of the pre-compression of the buffer spring 11 and adapts to different distance usage environments.

[0030] When tension is generated, the first pull tube 5 can slide relative to the elastic band. The tension is first absorbed by the buffer spring 11. Similarly, when a violent pull occurs, the buffer spring 11 will further absorb the tension, which plays a buffering role and prevents the tension from acting directly on the elastic band and causing it to break. This ensures that the elastic band itself is always within a safe force range. This device is suitable for many applications and is small in size, making it easy to carry or store.

[0031] The specific embodiments described herein are merely illustrative examples of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.
