Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to an elastic expander with adjustable resistance value. Background Art

[0002] An elastic expander is a kind of equipment suitable for mass fitness exercises. The benefits of using an elastic expander for exercise are as follows: The biceps brachii is a muscle with two heads, and its main function is to flex the arm. When flexing the arm, another muscle - the triceps brachii is also used. And only when doing some forearm-lifting exercises, such as high pulley curls or reverse high pulley curls, can the brachialis muscle be fully exercised. In addition, the brachioradialis, the main muscle in the upper part of the forearm, also plays a significant role in the arm-flexing movement, and the brachioradialis can be strengthened through side curls with an elastic expander.

[0003] The existing elastic expander mainly includes an elastic rope and handles provided at both ends of the elastic rope. After the handles and the elastic rope are assembled, the resistance value of the elastic expander cannot be adjusted, which cannot meet the needs of different people or different training stages. Summary of the Utility Model

[0004] The utility model aims at the above problems and provides an elastic expander with adjustable resistance value.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The present application provides an elastic expander with adjustable resistance value, including an elastic rope, handles and a buckle;

[0007] A connecting loop is formed on the handle, the elastic rope is threaded through the connecting loop, and a blocking member is connected to the end of the elastic rope passing through the connecting loop, and the blocking member is used to prevent the elastic rope from slipping out of the connecting loop;

[0008] The buckle is movably sleeved on the connecting loop. When the buckle moves towards the elastic rope side on the connecting loop, the opening of the connecting loop becomes smaller.

[0009] That is, by changing the position of the buckle on the connecting loop, the opening size of the connecting loop can be adjusted to facilitate the disassembly and installation of the elastic rope with the blocking member. Replacing the elastic rope with different resistance values can realize the adjustment of the resistance value of the elastic expander, so that the elastic expander provided by the present application can meet the needs of different people or different training stages.

[0010] Specifically, when the elastic cord needs to be replaced, move the buckle away from the elastic cord to enlarge the opening of the connecting loop. The elastic cord slips out of the connecting loop, and then replace it with another elastic cord of a suitable resistance value. When the elastic cord of a suitable resistance value is snapped onto the connecting loop through the blocking component, move the buckle closer to the elastic cord to make the opening of the connecting loop smaller and snap the elastic cord between the connecting loop and the buckle.

[0011] In addition, the existing structure of the tensioner mainly includes an elastic cord and handles provided at both ends of the elastic cord. During actual use, when stretching the elastic cord through the handles, the elastic cord is likely to break away from the handles, causing rebound and injuring the user. By providing the blocking component to prevent the elastic cord from slipping out of the connecting loop once, and the buckle to prevent the elastic cord from slipping out of the connecting loop a second time, the connection stability between the elastic cord and the handle of the tensioner is doubly guaranteed, avoiding the situation where the elastic cord breaks away from the handle and injures the user during use.

[0012] Furthermore, at least the elastic cord and the connecting loop are made of elastic soft rubber material.

[0013] During actual use, the entire tensioner including the handle and the buckle can be made of soft rubber materials such as TPR, TPE, and silicone. The elasticity of the elastic cord is greater than that of the connecting loop.

[0014] Furthermore, the blocking component is integrally formed with the elastic cord;

[0015] The connecting loop is integrally formed with the handle.

[0016] Furthermore, there are two handles, which are respectively arranged at both ends of the elastic cord;

[0017] Each handle is respectively provided with a plurality of the connecting loops, and the elastic cord includes multiple strands, and the multiple strands of elastic cords are respectively arranged at intervals on the connecting loops.

[0018] In addition to replacing each single elastic cord with different resistance values, the resistance value of the tensioner can also be adjusted by increasing or decreasing the number of elastic cords arranged on the handle.

[0019] Furthermore, the number of connecting loops on the handle is preferably 3 - 6. When the number of connecting loops is 5 or 6, the connecting loops can be arranged in two rows vertically in a staggered manner.

[0020] Furthermore, the connecting loop has an arc-shaped loop portion and a closing loop portion connected to the arc-shaped loop portion. The elastic cord is arranged at the position of the arc-shaped loop portion, and the buckle is arranged at the position of the closing loop portion.

[0021] Furthermore, the radial dimension of the arc-shaped loop portion is R, and the radial dimension of the blocking component is greater than or equal to 1.5R.

[0022] Further, the radial dimension of the blocking member is between 2R and 3R.

[0023] In actual use, the connecting ring is elastic, and when in a stretched state, it can allow a blocking member with a radial dimension larger than the arc-shaped ring portion to pass through.

[0024] Further, the blocking member is a sphere or a prism, preferably a sphere, so as to facilitate passing through the arc-shaped ring portion.

[0025] Further, a movable channel is formed on the buckle, and the buckle is sleeved on the connecting ring through the movable channel.

[0026] Further, separating convex ridges are formed on the inner wall of the movable channel, and the separating convex ridges divide the movable channel into a first channel portion and a second channel portion that communicate with each other;

[0027] The separating convex ridges are used to extend into the connecting ring to separate the two side ring bodies of the connecting ring;

[0028] The two side ring bodies of the connecting ring are respectively embedded in the first channel portion and the second channel portion.

[0029] The beneficial effects of the present utility model are:

[0030] (1) By providing a blocking member, the elastic cord is prevented from slipping out of the connecting ring once, and the buckle prevents the elastic cord from slipping out of the connecting ring a second time, so that the connection stability between the elastic cord of the tensioner and the handle is double-guaranteed, avoiding the situation that the elastic cord disengages from the handle and injures the user during use.

[0031] (2) The handle has a plurality of connecting rings. By increasing or decreasing the number of elastic cords arranged on the handle, or replacing each single elastic cord with a different resistance value, the resistance value of the tensioner can be adjusted. Description of the Drawings

[0042] The lock buckle 30 is movably mounted on the connecting ring 210 . When the lock buckle 30 moves on the connecting ring 210 toward the elastic cord 10 , the opening of the connecting ring 210 becomes smaller.

[0043] That is, by changing the position of the lock buckle 30 on the connecting ring 210, the size of the opening of the connecting ring 210 can be adjusted to facilitate the removal and installation of the elastic cord 10 with the blocking component 110. By replacing the elastic cord 10 with different resistance values, the resistance value of the tensioner can be adjusted, so that the tensioner provided by the present application can meet the needs of different groups of people or the needs of different training stages.

[0044] Specifically, when the elastic cord 10 needs to be replaced, the buckle 30 is moved to the side away from the elastic cord 10 to enlarge the opening of the connecting ring 210, and the opening of the connecting ring 210 is detached from the connecting ring 210, and another elastic cord 10 with a suitable resistance is replaced. When another elastic cord 10 with a suitable resistance is connected to the connecting ring 210 through the blocking component 110, the buckle 30 is moved to the side close to the elastic cord 10 to reduce the opening of the connecting ring 210 and enable the elastic cord 10 to be connected between the connecting ring 210 and the buckle 30.

[0045] In addition, the existing structure of the tensioner mainly includes an elastic cord 10 and handles 20 provided at both ends of the elastic cord 10. During actual use, when stretching the elastic cord 10 through the handles 20, the elastic cord 10 is likely to break away from the handles 20, causing a rebound and injuring the user. By providing a blocking member 110 to prevent the elastic cord 10 from slipping out of the connecting loop 210 once, and a buckle 30 to prevent the elastic cord 10 from slipping out of the connecting loop 210 a second time, the connection stability between the elastic cord 10 and the handles 20 of the tensioner is double-guaranteed, avoiding the situation where the elastic cord 10 breaks away from the handles 20 and injures the user during use.

[0046] In this embodiment, at least the elastic cord 10 and the connecting loop 210 are made of an elastic soft rubber material.

[0047] During actual use, the entire tensioner including the handles 20 and the buckle 30 can be made of soft rubber materials such as TPR, TPE, or silicone. The elasticity of the elastic cord 10 is greater than that of the connecting loop 210.

[0052] Each handle 20 is respectively provided with a plurality of connecting loops 210, the elastic cord 10 includes multiple strands, and the multiple strands of the elastic cord 10 are respectively arranged at intervals on the connecting loops 210.

[0053] In addition to replacing each single elastic cord with a different resistance value, the resistance value of the tensioner can also be adjusted by increasing or decreasing the number of elastic cords 10 provided on the handle 20.

[0054] In this embodiment, the number of connecting loops 210 on the handle 20 is 3.

[0055] In other embodiments, the number of connecting loops 210 on the handle 20 is 2 or more. When the number of connecting loops 210 is 5 or 6, the connecting loops 210 can be arranged in two rows in a staggered manner. When the number of connecting loops 210 is 1, the resistance value of the tensioner can only be adjusted by replacing the elastic cord with a different resistance value.

[0056] In this embodiment, the connecting ring 210 has an arc-shaped ring portion 211 and a closing ring portion 212 connected to the arc-shaped ring portion 211 , the elastic cord 10 is disposed at the position of the arc-shaped ring portion 211 , and the lock buckle 30 is disposed at the position of the closing ring portion 212 .

[0057] In this embodiment, the radial dimension of the arc-shaped ring portion 211 is R, and the radial dimension of the blocking component 110 is greater than or equal to 1.5R.

[0058] In this embodiment, the radial dimension of the blocking component 110 is 2.5R.

[0059] In actual use, the connecting ring 210 is elastic and can allow the blocking component 110 with a radial size larger than the arc-shaped ring portion 211 to pass through when in a stretched state.

[0060] In this embodiment, the blocking member 110 is a sphere so as to pass through the arc-shaped ring portion 211 .

[0061] In other embodiments, the blocking component 110 is a polygonal column, so as to enhance the blocking effect of the blocking component, that is, the blocking component is less likely to fall out of the arc-shaped ring portion 211 .

[0062] In this embodiment, a movable channel 310 is formed on the lock buckle 30 , and the lock buckle 30 is sleeved on the connecting ring 210 through the movable channel 310 .

[0063] In this embodiment, a partition rib 320 is formed on the inner wall of the active channel 310, and the partition rib 320 divides the active channel 310 into a first channel portion 311 and a second channel portion 312 that are interconnected.

[0064] The separation ridge 320 is used to extend into the connecting ring 210 to separate the two side ring bodies of the connecting ring 210;

[0065] The two side ring bodies of the connecting ring 210 are respectively embedded in the first channel portion 311 and the second channel portion 312 .

Next, the lock buckle 30 is moved to one side of the elastic cord 10, so that the elastic cord 10 is located in the arc-shaped ring portion 211 of the connecting ring 210 under the double locking action of the lock buckle 30 and the blocking component 110.

[0069] Embodiment 2

[0070] The difference between this embodiment and Embodiment 1 lies in the different structure of the buckle 30. In this embodiment, the buckle 30 is of a split structure. The buckle 30 includes two buckling bodies hinged together. After the two buckling bodies are buckled, they are fixed by a locking element. The locking element is detachably connected to the two buckling bodies. The locking element can specifically be a detachable fastener. The buckling-type buckle 30 can pass through the connecting ring 210 more conveniently and be sleeved on the necking ring portion 212 of the connecting ring 210; it is also convenient for replacing the elastic cord 10. That is, when assembling the tensioner, the blocking member 110 at the end of the elastic cord 10 can also be first passed through the arc-shaped ring portion 211 of the connecting ring 210, and then the buckle 30 is sleeved on the necking ring portion 212 of the connecting ring 210.
