[0002] With the increase of life pressure, people pay more and more attention to physical health. Fitness exercise is an important guarantee for enhancing physical health and has gradually become an important part of people's lives. Although there are many fitness exercise equipment, the tensioner is deeply loved by the majority of fitness enthusiasts as a simple and applicable fitness equipment.

[0003] When using a tensioner, some fitness movements require the use of a tensioner door clip (also called a door buckle) with the door as the fixed anchor point of the tensioner. Most of the existing tensioner door clips adopt Figure 1 the simple structure shown in the figure, including a hollow roller 1 and a webbing 2. The webbing 2 passes through the inside of the roller 1 to form a loop, and the two inner sides of the webbing 2 close to the roller 1 are sewn together so that the webbing forms two loops of different sizes, and the roller 1 is sleeved in the small loop. When in use, the end with the roller 1 is placed on one side outside the door, and then the door is closed so that the webbing 2 is clamped between the door seams for fixation. Then, one end of the tensioner is passed through the large loop, and some strength, stretching, and stretching exercises can be done through the tensioner.

[0004] However, for each specific model of this simple tensioner door clip, due to its fixed size, when fixing the tensioner, the tensioner only has one fixed anchor point height position and cannot adjust the position of the tensioner fixed anchor point according to the user's height and specific fitness exercises. Moreover, the large loop of the webbing is only suitable for passing through the tensioner and cannot be commonly used for multiple different tensioners.

[0005] Therefore, it is necessary to improve the existing door clip for fixing a tensioner. Summary of the Invention

[0006] The utility model provides a door clip for fixing a tensioner, which can solve the problems that the existing door clip for fixing a tensioner cannot adjust the position of the tensioner fixed anchor point and cannot be commonly used for multiple tensioners.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Refer to Figures 2 to 7, the door clip 1 for fixing the tensioner in this embodiment includes a first annular webbing 10 and a tensioner fixing assembly 20 provided on the first annular webbing 10. The tensioner fixing assembly 20 is used to fix the tensioner or the resistance band.

[0030] The tensioner fixing assembly 20 includes an adjustment buckle 21, a hook 22 connected to the adjustment buckle 21, and a threading loop 23. The hook 22 and the threading loop 23 are located radially outside the first annular webbing 10. The adjustment buckle 21 is provided on the first annular webbing 10 and is configured to be movable circumferentially along the first annular webbing 10 and locked after moving into place, that is, positioned at the position after moving into place.

[0031] When the door clip 1 for fixing the tensioner in this embodiment is in use, the entire door clip 1 for fixing the tensioner is sleeved on the door body 2 of the house through the first annular webbing 10, approximately at the center position in the width direction of the door body 2, and the door clip 1 for fixing the tensioner is kept under a certain degree of tension; then close the door (it can be locked). The top and bottom of the first annular webbing 10 are clamped in the upper and lower door seams. The door clip 1 for fixing the tensioner is firmly sleeved on the door body 2, and the tensioner fixing assembly 20 is located on the side where the door body 2 closes ( Figure 7 as shown, arrow I is the closing direction, and arrow II is the opening direction). For example, if turning inward is the closing direction, the tensioner fixing assembly 20 is located inside the door body 2; if turning outward is the closing direction, the tensioner fixing assembly 20 is located outside the door body 2, so that the load-bearing wall where the door body 2 is located serves as the second resistance for the door clip 1 for fixing the tensioner, improving the use safety; then, a tensioner with a hook can be hooked on the hook 22 of the tensioner fixing assembly 20 to perform relevant fitness exercises, or a tensioner with handles at both ends can be threaded through the threading loop 23 for relevant fitness training, or a resistance band without handles can be threaded through the threading loop 23 for relevant fitness training, etc. The position where the tensioner fixing assembly 20 is located is the tensioner fixing anchor point position.

[0032] When it is necessary to adjust the position of the tensioner fixing anchor point, open the adjustment buckle 21, move the entire tensioner fixing assembly 20 circumferentially along the first annular webbing 10, and then lock the adjustment buckle 21 after adjusting to the appropriate position. The adjustment is convenient.

[0033] Specifically, the first annular webbing 10 is formed by connecting the head and tail ends of a long strip of webbing through a snap buckle 30, as Figure 4 , Figure 6 shown. The first annular webbing 10 can specifically adopt a woven belt or a canvas belt, etc. The snap buckle 30 is a common lock form used in existing products such as belts and bag straps, and has two states: unlocking and locking. It is locked by pressing the lock tongue, and the lock tongue is pulled outwards to unlock. By operating the snap buckle 30, the annular circumference of the first annular webbing 10 can be conveniently adjusted, thereby adjusting its tightness on the door body 2.

[0034] Furthermore, as Figure 3 shown, a connecting shaft 24 parallel to the width direction of the webbing is provided on the adjusting buckle 21. Both ends of the connecting shaft 24 are connected to the housing of the adjusting buckle 21. A second annular webbing 25 is sleeved on the connecting shaft 24, that is, the connecting shaft 24 is located in the annular space of the second annular webbing 25. A first sewing line 26 and a second sewing line 27 are sewn on the second annular webbing 25. The second annular webbing 25 is separated into an adjusting buckle connecting ring 28, a hook connecting ring 29 and the threading ring 23 through the first sewing line 26 and the second sewing line 27. The hook connecting ring 29 and the threading ring 23 are located outside the adjusting buckle connecting ring 28. The hook 22 is threaded through the hook connecting ring 29.

[0035] Specifically, the second annular webbing 25 is formed by connecting the head and tail of a long strip of webbing. After its head end is wound around the connecting shaft 24, it is sewn together with the tail end. For example, it can be sewn at the position corresponding to the first sewing line 26, and the first sewing line 26 is formed after sewing. The second annular webbing 25 can specifically adopt a woven belt or a canvas belt, etc. The hook 22 can adopt a metal D-ring, or a triangular ring, an O-ring, etc.

[0036] Since the threading ring 23 has to pass through a tensioner with handles at both ends or a tension belt without handles, its inner diameter is larger than that of the adjusting buckle connecting ring 28 and the hook connecting ring 29, and its contact area with the tensioner or the tension belt is larger. To reduce the frictional damage between them, especially to reduce the friction with silicone material tensioners and tension belts such as rubber hose tensioners and annular sheet tension belts, and improve the service life of the tensioner or the tension belt, an elastic protective layer 210 can be fixedly arranged on the inner wall of the threading ring 23, such as a rubber layer, a foam layer, etc. There is no specific limitation here. Specifically, the elastic protective layer can be fixed by bonding or sewing.

[0037] In some embodiments of the present invention, as Figure 3 and Figure 6 shown, the tensioner fixing assembly 20 further includes an elastic protective cylinder 211. The elastic protective cylinder 211 is sleeved on the belt body of the first annular webbing 10 where the adjusting buckle 21 is located. The elastic protective cylinder 211 is not a complete cylindrical structure. A through portion 212 for avoiding the exposure of the adjusting buckle 21, the hook 22 and the threading ring 23 is formed on its circumferential side wall; when the adjusting buckle 21 moves along the circumferential direction of the first annular webbing 10, the adjusting buckle 21 pushes the elastic protective cylinder 211 to move synchronously.

[0038] Specifically, the elastic protective cylinder 211 can specifically adopt an elastic rubber cylinder or a sponge cylinder. Since the adjusting buckle 21 generally needs to have a certain structural strength and hardness, such as existing metal buckles, plastic buckles, etc. are selected. In this embodiment, after the door clip 1 is installed on the door body 2, contacting the door body 2 through the elastic protective cylinder 211 can avoid the door body 2 being scratched and damaged due to the direct contact between the adjusting buckle 21 and the door body 2.

[0039] To facilitate processing and disassembly and assembly on the first annular webbing 10, the original shape of the elastic protective tube 211 can be a sheet-like structure, and a portion of the material corresponding to the through portion 212 can be removed by cutting, and then the sheet webbing is wound around the first annular webbing 10, and Velcro can be set at the joints between the head and the tail to connect them, so as to form a cylindrical elastic protective tube 211.

[0040] In some embodiments of the present invention, there are multiple tensioner fixing assemblies 20, which are arranged at intervals along the circumference of the first annular webbing 10 on the same half of the belt body of the first annular webbing 10. Specifically, based on the installation state on the door body 2, all tensioner fixing assemblies 20 are on the same side of the door body 2, that is, the side of the door body 2 closing direction, and are all facing the user.

[0041] Figure 2 , Figure 5 and Figure 7 Two tensioner fixing assemblies 20 are used as an example for schematic illustration, but the number is not limited to two.

[0042] By setting up multiple tensioner fixing assemblies 20, the tensioners or tension belts cooperate with tensioner fixing assemblies 20 of different heights, which can provide users with a variety of fitness training methods, improve the flexibility and convenience of using the door clamp 1; and at the same time, it can also adapt to users of different heights.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
