Description

Technical Field

[0001] The utility model relates to the technical field of rope buckles, in particular to a rope buckle which can be locked automatically. Background Art

[0002] A cord buckle is a device used to adjust and set the length of drawstrings, pull cords, shoelaces, etc. Common cord buckles include push-type spring buckles and mesh buckles. Push-type spring buckles, such as the style in patent CN202320024273.4, are generally used to adjust the tightness of drawstrings on clothing. The problems are: 1. When the rope needs to be tightened, one hand must press the spring buckle while the other hand pulls the rope, and it cannot be operated with one hand. 2. This type of product relies on the force of the spring to fix the rope. Generally, the cord buckle is small in size and cannot be equipped with a spring buckle with a stronger force. In addition, the spring is prone to aging and the force decreases with use. When locked, the rope is easy to move in the spring buckle hole and become loose.

[0003] The eyelet buckle is generally used to adjust the length of a wider flat belt, such as a backpack strap. It can be automatically locked by the tension generated by the flat belt, such as the style in patent CN201620246920.6, but its scope of application is small. The same eyelet buckle can only adapt to flat belts of corresponding widths, and cannot be used for flat belts of different widths or ropes of other shapes. In addition, although this product is locked more firmly in a static state, the flat belt will also be more likely to loosen when there is more shaking in a sports scene. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a rope buckle that can be automatically locked. The rope buckle has a simple structure and is suitable for threading round or flat-shaped ropes. The force from the rope buckle locks the threaded rope, making it more secure.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rope buckle that can be automatically locked includes two groups of side walls arranged opposite to each other, positioning columns connecting the two groups of side walls and at least one group of adjustment units connected to the side walls. A first through hole is provided between the two side walls, and a second through hole is provided in the adjustment unit. The aperture of the second through hole at one end away from the first through hole is reduced to limit the position of the threaded rope and achieve locking.

[0007] Preferably, the adjustment unit includes a group of inclined walls connected to one side wall thereof or two groups of inclined walls respectively connected to the side walls; a blocking wall is connected to the side of the inclined wall away from the side wall; the inclined wall gradually reduces the aperture of the second perforation toward the blocking wall; the inclined wall limits the position of the rope and can conveniently adapt to ropes of various different widths.

[0008] Preferably, the adjusting unit includes two sets of connecting side walls respectively connected to the side walls and a blocking wall connected to the two sets of connecting side walls. One set of connecting side walls is provided with a blocking member towards the blocking wall, or the two sets of connecting side walls are simultaneously provided with blocking members towards the blocking wall, and the threading is limited by the blocking members.

[0009] Preferably, the blocking member extends to the side wall, and the distance between the blocking member and the connecting side wall or the inclined wall gradually decreases towards the blocking wall. The blocking member limits the threading and can conveniently adapt to various widths of threading at the same time.

[0010] Preferably, the height of the blocking wall is lower than the height of the positioning post.

[0011] Preferably, at least one set of connecting members is provided on the side of the side wall away from the positioning post for connecting to clothing or a cord.

[0012] Preferably, the connecting member is at least one set of connecting rods located between the two sets of side walls; further, openings are provided on the connecting rods to facilitate removing the cord buckle from the clothing or the cord.

[0013] Or the connecting member is an arc-shaped ring or a hole connected to the side wall;

[0014] Preferably, openings are provided on the arc-shaped ring or the hole to facilitate removing the cord buckle from the clothing or the cord.

[0015] Or the connecting member is a hollow tube connected to the side wall;

[0016] Or the connecting member is a C-shaped hook connected to the side wall;

[0017] Or the connecting member is a female buckle that cooperates with a male buckle on the clothing or the cord,

[0018] Or the connecting member is a male buckle that cooperates with a female buckle on the clothing or the cord to quickly connect to the clothing or the cord.

[0019] Preferably, the bottom surface of the side wall is a horizontal surface, a convex surface protruding outwards or a concave surface recessed inwards to adapt to the curved surface of the object to be locked.

[0020] Preferably, multiple sets of adjusting units arranged in sequence are provided at any end of the two sets of side walls to lock multiple sets of threading.

[0021] Preferably, one set of adjusting units or multiple sets of adjusting units arranged in sequence are respectively provided at both ends of the two sets of side walls to lock at least two sets of threading.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] 1. The firmness is stronger. This kind of rope buckle structure determines that the tighter the rope is stretched, the stronger the acting force for locking the rope from the rope buckle will be.

[0025] 2. The operation is simpler and more convenient. Unlike traditional spring buckles, there is no need to press the buckle body when tightening or loosening the rope. When tightening the rope of this rope buckle, only the action of stretching the rope is needed. When loosening the rope, just pinch the buckle body and pull it outwards to complete the operation, and the friction between the rope and the rope buckle during the stretching process is small and it is not laborious.

[0026] 3. The adaptation range is wide. Common flat ropes, round ropes, semi-circular ropes, etc. can all be applicable to this product, and it can adapt to a relatively large range of rope widths.

[0027] 4. The volume can be made very small, which has little impact on the object to be locked. When applied to clothing, it is more beautiful and not obtrusive.

[0028] 5. The cost is significantly lower than other products with the same use, such as push-button spring buckles, and the service life is also longer. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0063] Embodiment 1: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked, including two groups of oppositely arranged side walls 1, a positioning post 2 connecting the two groups of side walls 1, and at least one group of adjusting units 3 connected to the side walls 1. A first through hole 10 is provided between the two side walls 1, and a second through hole 20 is provided in the adjusting unit 3. The aperture of the end of the second through hole 20 far from the first through hole 10 is reduced to limit the threading of the rope to achieve locking.

[0064] The adjusting unit 3 includes a group of inclined walls 31 connected to one of its side walls 1. A blocking wall 32 is connected to the side of the inclined wall 31 far from the side wall 1. The inclined wall 31 gradually reduces the aperture of the second through hole 20 towards the blocking wall 32. The inclined wall 31 limits the threading of the rope and can conveniently adapt to ropes of various different widths at the same time.

[0065] Embodiment 2: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: the adjusting unit 3 includes two groups of inclined walls 31 respectively connected to the side wall 1. A retaining wall 32 is connected to the side of the inclined wall 31 away from the side wall 1. The inclined wall 31 gradually reduces the aperture of the second through hole 20 towards the retaining wall 32. The inclined wall 31 limits the position of the threading rope and can conveniently adapt to threading ropes of various different widths at the same time.

[0066] Embodiment 3: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: the adjusting unit 3 includes two groups of connecting side walls 33 respectively connected to the side wall 1 and a retaining wall 32 connected to the two groups of connecting side walls 33. A blocking member 34 is provided on one group of connecting side walls 33 towards the retaining wall 32, and the threading rope is limited by the blocking member 34.

[0067] Embodiment 4: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: the adjusting unit 3 includes two groups of connecting side walls 33 respectively connected to the side wall 1 and a retaining wall 32 connected to the two groups of connecting side walls 33. Blocking members 34 are provided on the two groups of connecting side walls 33 towards the retaining wall 32 at the same time, and the threading rope is limited by the blocking members 34.

[0068] Embodiment 5: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: the adjusting unit 3 includes two groups of connecting side walls 33 respectively connected to the side wall 1 and a retaining wall 32 connected to the two groups of connecting side walls 33. A blocking member 34 is provided on the connecting side wall 33 towards the retaining wall 32, and the threading rope is limited by the blocking member 34; the blocking member 34 extends to the side wall 1. The blocking member 34 extending to the side wall 1 can improve the stability of the function of limiting the position of the threading rope, and at the same time is beneficial to reducing the overall volume of the rope buckle and enhancing the overall structural strength of the rope buckle; and the distance between the two opposite blocking members 34 gradually decreases towards the retaining wall 32. The blocking member 34 limits the position of the threading rope and can conveniently adapt to threading ropes of various different widths at the same time.

[0069] As Figure 5 shown, after the tight-rope operation is completed, during the process of the rope being tightened by the object to be locked, when the lower-positioned rope moves towards the upper-positioned rope, the blocking member 34 contacts the upper-positioned rope and presses the upper-positioned rope to the place where the rope buckle applies the acting force, realizing the automatic locking function. If the edge of the blocking member 34 is not smooth, it will affect the moving speed of the lower-positioned rope towards the upper-positioned rope, and the automatic locking function will not proceed smoothly, which may cause the rope to loosen.

[0085] Embodiment 18: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: a third through hole is provided from the side of any one adjusting unit 3 to the side wall 1, that is, the third through hole extends from the side of the adjusting unit 3 to the side of the side wall 1 to cooperate with the threading ropes to form a butterfly rope buckle shape, see Figure 28 and Figure 29 .

[0086] Embodiment 19: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: a third through hole is provided on any one adjusting unit 3 to the side wall 1 located in the opposite direction of it, that is, the third through hole extends from the side of one adjusting unit 3 to the side of the side wall 1 on the other side to cooperate with the threading ropes to form a butterfly rope buckle shape; an opening is provided on the connecting ring 5 to facilitate removing the threading ropes; see Figure 30 and Figure 31 .

[0087] Embodiment 20: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: a third through hole is provided on the side wall 1, or a third through hole is provided on the connecting member 4 to cooperate with threading to form a shape of a butterfly rope buckle; alternatively, a third through hole can be formed between the side wall 1 or the adjusting unit 3 or the connecting member 4 and the connecting ring 5 to cooperate with threading to form a shape of a butterfly rope buckle.

[0088] Embodiment 21: A preferred embodiment of the present utility model provides a rope buckle that can be automatically locked. The difference from the above embodiment is only that: a connecting ring 5 is provided on the side wall 1 or the adjusting unit 3 or the connecting member 4.

[0089] During installation, a threading (such as a shoelace) is connected to the connecting member 4 for connecting to clothing or a rope belt; another threading passes through the first through hole 10, then winds around the positioning post 2 and passes through the second through hole 20. Note that in the second through hole 20, the rope located in the lower position should press the threading located in the upper position. Only by maintaining this state can the threading be locked. The settings of the inclined wall 31 and the blocking member 34 are to keep the two sections of the rope from swapping relative positions, so that they always exert forces on each other to maintain the lock. At the same time, since only part of the structure in the second through hole 20 has a limiting function by squeezing the rope, the friction force when the rope moves in the second through hole 20 is small, and the second through hole 20 can also conveniently adapt to various widths of threading.

[0090] When the rope is tightened, an upward force is applied to the adjusting unit 3, and the blocking wall 32 will apply a downward force to the rope. Coupled with the pulling force of the rope in the lower position, it will be converted into an upward force. They squeeze each other, increasing the friction force between them and achieving the locking effect. Moreover, the greater the pulling force of the rope, the greater the force exerted by the rope buckle. Therefore, the locking firmness of this rope buckle is relatively high.

[0091] When pulling the rope, pull the rope in the upper position outwards, and the rope in the upper position and the rope buckle will start to move away from the rope in the lower position, gradually reducing the force on the rope in the lower position, so that the rope can move in the second through hole 20.

[0092] When loosening the rope, lift the rope buckle, an upward force will be applied to the rope buckle, which will destroy the downward force of the blocking wall 32 on the rope. In addition, as the end of the side wall 1 gradually starts to move away from the rope, the rope can move in the second through hole 20 to complete the rope loosening.
