Description

Technical Field

[0001] This utility model relates to the field of elastic rope technology, and more specifically, to an adjustable elastic rope. Background Technology

[0002] Elastic ropes, as one type of rope, have stronger elasticity compared to traditional ropes. They are often used to exercise the user's physique by utilizing the gravity generated when pulling.

[0003] Publication number CN204447090U discloses an elastic rope, the technical solution of which includes an elastic latex tube, a cloth sleeve, a rubber protective sleeve and a plug. The elastic latex tube is wrapped with a cloth sleeve, the end of the elastic latex tube is fixedly connected to the end of the cloth sleeve, a rubber protective sleeve is fitted on the outer wall of the end of the cloth sleeve, and a plug is fitted to the end of the rubber protective sleeve.

[0004] The above technical solution makes the elastic latex tube less susceptible to oxidation and extends its service life by covering it with a cloth sleeve. It also prevents injury to the human body if the latex tube breaks. However, the above technical solution does not include a structure on the elastic cord for adjusting its length, making it difficult for users to adjust the length of the elastic cord according to their own needs.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable elastic rope, which solves the problem that it is difficult for users to adjust the length of the elastic rope according to their own needs.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable elastic rope, including an elastic rope body and an adjusting tube, wherein the elastic rope body and the adjusting tube are internally slidably connected, one end of the elastic rope body is detachably connected to the outer wall of the adjusting tube, a through groove is opened on the side wall of the adjusting tube extending to the elastic rope body, an adjusting plate is rotatably connected in the through groove, the adjusting plate and the through groove are connected by a torsion spring, and a number of limiting teeth are fixedly connected to the side of the adjusting plate near the elastic rope body. When the torsion spring is in its natural state, the adjusting plate is tilted and the limiting teeth are inserted into the elastic rope body.

[0008] By adopting the above technical solution, when further adjustment of the elastic cord's length is needed, pressure is applied to the adjusting plate, causing it to rotate and simultaneously causing the torsion spring to undergo elastic deformation. The elastic cord body is then passed through the adjusting tube, folded over, and one end of the elastic cord body is attached to the outer wall of the adjusting tube. Pulling the elastic cord body then moves it along the inner wall of the adjusting tube towards its folded end. At this point, the elastic cord body is affected by its folded end, causing its length to shorten, thus achieving the effect of adjusting the length of the elastic cord. As a result, once the length of the elastic cord is adjusted, the pressure applied to the adjusting plate is released. At this time, the torsion spring loses its restriction and deforms to its original position, driving the adjusting plate back to its original position. Simultaneously, the limiting tooth is inserted into the body of the elastic cord. The body of the elastic cord is then restricted by the limiting tooth, preventing it from moving and thus achieving the effect of fixing the elastic cord. When the elastic cord is subjected to tension for a long time, the body of the elastic cord is restricted by the limiting tooth because it is inserted into the body of the elastic cord, thus preventing the length of the elastic cord from changing when it is continuously subjected to tension.

[0009] The present invention is further configured such that: a connecting plate is fixedly connected to the side wall of the through groove, a pressing plate is slidably connected to the side wall of the connecting plate, and the side wall of the pressing plate and the adjusting piece are in contact with each other.

[0010] By adopting the above technical solution, when the adjusting plate is driven to rotate, pressure is applied to the pressing plate, causing the pressing plate to move downward along the connecting plate. At the same time, since the pressing plate and the adjusting plate are in contact with each other, the pressing plate can drive the adjusting plate to rotate while moving downward. The pressing plate makes it easy for the user to drive the adjusting plate to rotate, which is convenient for the user to operate. When the pressure on the pressing plate is released, the torsion spring can drive the adjusting plate back to its original position, and the adjusting plate can drive the pressing plate back to its original position, which is convenient for subsequent secondary operations.

[0011] The present invention is further configured such that: a limiting block is fixedly connected to one side of the pressing plate, and a limiting groove is provided on the side wall of the connecting plate for the limiting block to slide.

[0012] By adopting the above technical solution, it is possible to prevent the pressing plate and the connecting plate from separating while the pressing plate is moving, thus avoiding affecting the movement of the adjusting plate driven by the pressing plate.

[0013] The present invention is further configured such that: a groove is provided on the side of the adjusting plate near the pressing plate, and a rotating rod is rotatably connected in the groove, and the rotating rod and the pressing plate are in contact with each other.

[0014] By adopting the above technical solution, the friction between the pressing plate and the adjusting plate can be reduced, and the adjusting plate can be easily driven to rotate when the pressing plate moves downward.

[0015] The present invention is further configured such that: a fixing cap is fixedly connected to one end of the elastic rope body; a placement groove for placing the fixing cap and the elastic rope body is opened on one side of the adjusting tube; a limiting plate is rotatably connected to the opening of the placement groove; a locking block is fixedly connected to the outer wall of the adjusting tube; and a locking groove for locking the locking block is opened on the side wall of the limiting plate.

[0016] By adopting the above technical solution, when fixing one end of the elastic rope body and the adjusting tube together, the fixing cap and the elastic rope body are placed in the placement groove. Then, the limiting plate is rotated to cover the opening of the placement groove, and the limiting plate and the adjusting tube are brought into contact with each other. Then, the locking block is driven into the locking groove and engages with the locking groove. The locking device fixes the limiting plate and the side wall of the adjusting tube together. At this time, the fixing cap and the elastic rope body located in the placement groove are restricted by the limiting plate, so that the elastic rope body cannot be separated from the fixing cap and the elastic rope body, thereby achieving the effect of fixing the elastic rope body and the adjusting tube together.

[0017] The present invention is further configured such that: the elastic rope body includes a plurality of elastic cores and two wear-resistant layers, the elastic cores are located between the two wear-resistant layers and are fixedly connected to the wear-resistant layers, and the limiting teeth are respectively located between two adjacent elastic cores.

[0018] By adopting the above technical solution, when the limiting teeth are inserted into the elastic cord body, damage to the elastic core can be avoided, thereby preventing the elasticity of the elastic cord body from being affected. At the same time, by using the wear-resistant layer, the wear resistance of the elastic cord body can be effectively improved, the wear on the elastic cord body can be reduced, and the service life of the elastic cord body can be increased.

[0019] In summary, this utility model has the following beneficial effects: when the elastic rope is subjected to tension for a long time, the setting of the adjusting plate and the torsion spring can drive the limiting tooth to always be inserted into the body of the elastic rope. Since the limiting tooth is inserted into the body of the elastic rope, the body of the elastic rope is restricted by the limiting tooth and cannot move, thereby achieving the effect of preventing the length of the elastic rope from changing when the elastic rope is continuously subjected to tension.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] An adjustable elastic cord, such as Figures 1-6As shown, the device includes an elastic rope body and an adjusting tube 1. The elastic rope body and the adjusting tube 1 are internally slidably connected. One end of the elastic rope body is detachably connected to the outer wall of the adjusting tube 1. A through groove 2 extending through to the elastic rope body is opened on the side wall of the adjusting tube 1. An adjusting plate 3 is rotatably connected in the through groove 2. The adjusting plate 3 and the through groove 2 are connected by a torsion spring 4. Several limiting teeth 5 are fixedly connected to the side of the adjusting plate 3 near the elastic rope body. When the torsion spring 4 is in its natural state, the adjusting plate 3 is tilted and the limiting teeth 5 are inserted into the elastic rope body.

[0031] When further adjustment of the elastic cord length is needed, pressure is applied to the adjusting plate 3, causing it to rotate and simultaneously causing the torsion spring 4 to undergo elastic deformation. The elastic cord body is then passed through the adjusting tube 1, folded over, and one end of the elastic cord body is attached to the outer wall of the adjusting tube 1. The elastic cord body is then pulled, causing it to move along the inner wall of the adjusting tube 1 towards its folded end. At this point, the elastic cord body is affected by its folded end, causing its length to shorten, thus achieving the effect of adjusting the elastic cord length. After the length adjustment is completed, the pressure applied to the adjusting plate 3 is released. At this time, the torsion spring 4 loses its restriction and deforms to restore its original position, driving the adjusting plate 3 back to its original position. At the same time, the limiting tooth 5 is inserted into the elastic rope body. At this time, the elastic rope body is restricted by the limiting tooth 5, so that the elastic rope body cannot move, thereby achieving the effect of fixing the elastic rope. When the elastic rope is subjected to tension for a long time, because the limiting tooth 5 is inserted into the elastic rope body, the elastic rope body is restricted by the limiting tooth 5 and cannot move, thereby achieving the effect of preventing the length of the elastic rope from changing when the elastic rope is continuously subjected to tension.

[0032] like Figures 1-5As shown, a connecting plate 6 is fixedly connected to the side wall of the through groove 2, and a pressing plate 7 is slidably connected to the side wall of the connecting plate 6. The side wall of the pressing plate 7 and the adjusting plate 3 are in contact with each other. When the adjusting plate 3 is driven to rotate, pressure is applied to the pressing plate 7, causing the pressing plate 7 to move downward along the connecting plate 6. At the same time, since the pressing plate 7 and the adjusting plate 3 are in contact, the pressing plate 7 can drive the adjusting plate 3 to rotate while moving downward. The pressing plate 7 makes it easy for the user to drive the adjusting plate 3 to rotate, which is convenient for the user to operate. When the pressure on the pressing plate 7 is released, the torsion spring 4 can drive the adjusting plate 3 back to its original position. At the same time, the adjusting plate 3 drives the pressing plate 7 back to its original position, which facilitates subsequent secondary operations. A limiting block 8 is fixedly connected to one side of the pressing plate 7. A limiting groove 9 is provided on the side wall of the connecting plate 6 for the limiting block 8 to slide. This can prevent the pressing plate 7 and the connecting plate 6 from separating while the pressing plate 7 is moving, thus avoiding affecting the pressing plate 7's ability to drive the adjusting plate 3 to move. A groove 10 is provided on the side of the adjusting plate 3 near the pressing plate 7. A rotating rod 11 is rotatably connected in the groove 10. The rotating rod 11 and the pressing plate 7 are in contact with each other, which can reduce the friction between the pressing plate 7 and the adjusting plate 3. When the pressing plate 7 moves downward, it is easy to drive the adjusting plate 3 to rotate.

[0033] like Figure 5 As shown, a fixing cap 12 is fixedly connected to one end of the elastic rope body. A placement groove 13 is provided on one side of the adjusting tube 1 for placing the fixing cap 12 and the elastic rope body. A limiting plate 14 is rotatably connected to the opening of the placement groove 13. A locking block 15 is fixedly connected to the outer wall of the adjusting tube 1. A locking groove 16 is provided on the side wall of the limiting plate 14 for locking the locking block 15. When fixing one end of the elastic rope body and the adjusting tube 1 together, the fixing cap 12 and the elastic rope body are placed in the placement groove 13. Then, the limiting plate 14 is rotated to cover the opening of the placement groove 13 and to make the limiting plate 14 and the adjusting tube 1 come into contact with each other. Then, the locking block 15 is driven into the locking groove 16 and locks with the locking groove 16. At this time, the fixing cap 12 and the elastic rope body located in the placement groove 13 are restricted by the limiting plate 14, so that the elastic rope body cannot be separated from the fixing cap 12 and the elastic rope body, thereby achieving the effect of fixing the elastic rope body and the adjusting tube 1 together.

[0034] like Figure 6 As shown, the elastic rope body includes several elastic cores 17 and two wear-resistant layers 18. The elastic cores 17 are located between the two wear-resistant layers 18 and are fixedly connected to the wear-resistant layers 18. The limiting teeth 5 are located between two adjacent elastic cores 17. When the limiting teeth 5 are inserted into the elastic rope body, they can prevent the limiting teeth 5 from damaging the elastic cores 17, thereby avoiding affecting the elasticity of the elastic rope body. At the same time, by using the wear-resistant layers 18, the wear resistance of the elastic rope body can be effectively improved, the wear on the elastic rope body can be reduced, and the service life of the elastic rope body can be increased.

[0035] The working principle of this utility model is as follows: When it is necessary to further adjust the length of the elastic rope, pressure is applied to the adjusting plate 3, which drives the adjusting plate 3 to rotate the limiting tooth 5, and at the same time drives the torsion spring 4 to undergo elastic deformation. Then, the elastic rope body is passed through the adjusting tube 1, and then the elastic rope body is folded over. One end of the elastic rope body is installed with the outer wall of the adjusting tube 1. Then, the elastic rope body is pulled, which drives the elastic rope body to move along the inner wall of the adjusting tube 1 towards its folded point. At this time, the elastic rope body is affected by its own folded point, which shortens the length of the elastic rope body, thereby achieving the effect of adjusting the length of the elastic rope.

[0036] After the elastic cord length is adjusted, the pressure applied to the adjusting plate 3 is released. At this time, the torsion spring 4 loses its restriction and deforms to restore its original position, driving the adjusting plate 3 back to its original position. Simultaneously, the limiting tooth 5 is inserted into the elastic cord body. At this time, the elastic cord body is restricted by the limiting tooth 5, preventing the elastic cord body from moving, thus achieving the effect of fixing the elastic cord. When the elastic cord is subjected to tension for a long time, because the limiting tooth 5 is inserted into the elastic cord body, the elastic cord body is restricted by the limiting tooth 5 and cannot move, thus achieving the effect of preventing the elastic cord length from changing when the elastic cord is continuously subjected to tension.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
