Detailed Implementation

[0015] 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.

[0016] like Figures 1-6 As shown, the tensioning strap with automatic webbing storage function in this embodiment includes a main unit 1, a first strap 4 and a second strap 5, wherein: the main unit 1 includes a housing 10 and a strap buckle assembly 2, the housing 10 is provided with a tape winding assembly 3 and a main unit housing strap outlet 114, and the strap buckle assembly 2 is connected and fixed to the outside of the main unit housing strap outlet 114.

[0017] The winding assembly 3 of this invention includes a rotatable spring box 31 and a spring 32 that drives its rotation. The spring 32 is disposed within the cavity of the spring box 31, and its outer end is fixedly connected to the spring box slot 366. The housing 10 is formed by fastening a rear housing 11 and a front housing 12 together, and its side wall is provided with a main housing strap outlet 114 for the first strap 4 to pass through. The spring box 31 is pivotally mounted on the housing main shaft 111 on the rear housing 11, while the inner end of the spring 32 is fixedly connected to the slot inside the main shaft 113 of the main housing rear housing. The spring box 31 is formed by fastening a rear housing 311 and a front housing 312 together. This connection can also be made using conventional methods such as self-tapping screws or glue, preferably plastic clips. The rear housing 11 and the front housing 12 are connected by connecting screws 7, or conventional methods such as plastic clips or glue.

[0018] The strap buckle assembly 2 includes a strap buckle base 23 and a strap buckle pressure plate 22, connected by a strap buckle rivet 25 and a strap buckle torsion spring 24. The rear end of the strap buckle base 23 is connected to the second strap 5. Specifically, one end of the second strap 5 is connected to the rear fixing shaft 223 of the strap buckle base by sewing a strap loop. The housing 10 has an opening at this location, allowing the other end of the second strap 5 to extend out of the housing 10. The first strap 4 is locked through the front locking channel 222 of the strap buckle. In the default state, the strap buckle pressure plate 22 closes the front locking channel 222 of the strap buckle due to the action of the rivet 25 and the strap buckle torsion spring 24, thereby locking the first strap 4, which can only be moved along... Figure 5 Arrow A can be pulled in one direction only, and cannot be pulled in the opposite direction. The first strap 4 can be released by pressing the strap buckle plate 22. When the second strap 5 and the outer end of the first strap 4 are tightened, the second strap 5 and the strap buckle base 23 form a straight line, and the position and shape of the housing 10 avoid this straight line area.

[0019] The above-described strap buckle assembly structure is an existing structure and will not be described in detail here. Of course, the structure of the strap buckle assembly is not limited to this; other similar conventional structures or modified structures can be used.

[0020] In this invention, the end of the first binding strap webbing roll 44 is fixedly connected to the spring box webbing fixing piece 367, and the first binding strap webbing roll 44 is wound around the spring box 31, extending out of the main housing through the main housing binding strap outlet 114 to reach the tensioning area binding strap 43. The connection method of the end of the first binding strap webbing roll 44 being fixedly connected to the spring box webbing fixing piece 367 is as follows: the end of the first binding strap webbing roll 44 has a corresponding webbing loop sewn onto the spring box webbing fixing piece 367, or it can be connected by conventional methods such as glue or plastic part compression.

[0021] After the first strap 4 reaches the tensioned area strap 43 position, it then passes through the locking channel 222 at the front of the strap buckle of the strap buckle assembly 2, and then reaches the position of the outer part 41 of the first strap and connects with the first strap hook 42.

[0022] like Figure 5 , 6 The following describes the process of using this utility model to bind goods: Press the strap buckle 22, and the first strap 4 will automatically retract. At this time, the first strap 4 can also be pulled out freely. After the first strap hook 42 and the second strap hook 52 are fixedly connected, pinch the tension area strap 43 and pull it in the direction of arrow A. At this time, the outer part 41 of the first strap will move in the direction of arrow B until the webbing or goods are tightened. Then, release the tension area strap 43. The excess webbing in the tension area strap 43 will be automatically retracted into the main unit 1 under the action of the tape winding assembly 3. The binding and tightening work is completed, avoiding the tedious cable management process before and after.

[0023] like Figure 5 , 6 To describe the process of using this utility model to untie goods, press the strap buckle plate 22. During the pressing process, pull out part of the first strap 4 so as to remove the first strap hook 42 and the second strap hook 52. At this time, continue to press the strap buckle plate 22, and the first strap 4 will automatically retract until the retraction is completed.

[0024] The unique feature of this invention is the rational combination of the tape winding assembly 3 and the strap buckle assembly 2 through the aforementioned housing 10. The tape winding assembly 3 automatically collects excess webbing from the first strap 4. When reeling in the thread, pressing the strap buckle pressure plate 22 in the strap buckle assembly 2 automatically reels in the thread. When tightening is required, pinching the tightening area strap 43 and pulling in the direction of arrow A completes the tightening operation. Releasing the hand automatically retracts the excess webbing. The entire process of binding and unbinding is automatic thread reeling, which is very convenient. At the same time, the strap buckle assembly 2 isolates the strap from the enormous tensile force it experiences during operation when locked. Therefore, the aforementioned housing 10 does not need to bear the enormous tensile force experienced by the strap during operation, allowing for the use of lighter and more economical plastic materials to make the main housing and tape winding assembly, making the product itself more compact, lightweight, and economical.
