Description

A skipping rope with adjustable length

technical field

The utility model relates to the field of sporting goods, in particular to a skipping rope with adjustable length.

Background technique

At present, in various primary and secondary schools and gymnasiums, rope skipping, as a kind of sports with low cost and high exercise efficiency, is gradually favored by various sports enthusiasts. Existing skipping rope is generally made by connecting handles at two ends of the rope, and its structure is simple, and it is also more convenient to carry.

However, the inventor has found that the currently used skipping ropes still have many inconveniences during use. When the rope is short, the problem of lengthening the rope cannot be well solved; when the rope is long, how to shorten the rope also brings certain inconvenience to the user.

Therefore, the utility model discloses a skipping rope with adjustable length to solve the deficiencies and defects of existing skipping ropes.

Utility model content

In view of the above existing problems at present, a skipping rope with adjustable length is provided, which can conveniently adjust the length of the skipping rope to be suitable for different users.

In order to achieve the above object, the technical solution adopted by the utility model is:

A skipping rope with adjustable length, comprising an end cover, a handle and a rope; the handle is a hollow structure with small holes at the bottom; the end cover is rotatably mounted on the upper part of the handle, and a worm is fixed at the lower end; the worm The other end of the shaft is fixed through the fixed shaft, and a worm gear is meshed on one side; a worm gear shaft is provided in the middle of the worm gear; the worm gear shaft is rotatable and fixed to the inner wall of the handle; a take-up wheel is fixed on the worm gear shaft, and the two are interference fit; The two ends of described rope are fixed on the take-up reel.

Preferably, a ring is arranged on the top of the end cover, and a nylon strap is arranged on the ring, which is convenient for hanging the skipping rope when it is not in use, does not take up space, and is also easy to find.

Preferably, the top of the handle is provided with an inner convex ring, the end cap is provided with an annular groove, the annular groove matches the inner convex ring, and the lower end of the annular groove is provided with an outer convex ring, The outer diameter of the outer convex ring is smaller than the inner diameter of the handle and larger than the inner diameter of the inner convex ring, which is beneficial to prevent the end cap from falling off.

Preferably, the diameter of the small hole is larger than the outer diameter of the rope, which facilitates the passing of the rope through the handle.

Preferably, the handle and the end cap are made of plastic, which are light in weight and easy to carry.

Owing to adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

The rotation of the end cover relative to the handle drives the worm to rotate, and the rotation of the worm drives the worm to rotate. Since the worm and the take-up wheel are fixedly mounted on the worm shaft, Driven by the rotation of the worm wheel, the worm wheel shaft also drives the rotation of the take-up wheel, and the rope fixed on the take-up wheel follows the rotation of the take-up wheel to realize rope winding or unwinding function, so as to well solve the problem that the length of the rope is difficult to adjust in the current skipping rope; at the same time, due to the effect of the fixed shaft, it can better ensure that the worm wheel shaft drives the worm wheel to rotate smoothly, and also Effectively play the role of defining the axis of the worm and strengthening the stability; finally, because the worm gear mechanism has a self-locking effect, only the rotation of the worm can drive the rotation of the worm wheel, and the worm wheel cannot drive the worm wheel in turn. The worm rotates, so when the length of the rope is adjusted, its length will not change during use, which is convenient for users to use the utility model product better.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are part of the embodiments of the present utility model, rather than 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 work belong to the present invention. The scope of utility model protection.

As shown in Figures 1 and 2:

A jumping rope with adjustable length, comprising an end cap 2, a handle 1 and a rope 3; the handle 1 is a hollow structure with a small hole 14 at the bottom; the end cap 2 is rotatably mounted on the upper part of the handle 1, and the lower end is fixed with Worm 6; the other end of the worm 6 is fixed through the fixed shaft 8, and a worm wheel 7 is engaged on one side; the middle part of the worm wheel 7 is provided with a worm wheel shaft 10; the worm wheel shaft 10 is rotatably fixed to the inner wall of the handle 1; the worm wheel shaft 10 is fixed There is a take-up reel 9, and the two are interference fit; the two ends of the rope 3 are fixed on the take-up reel 9.

The top of the end cover 2 is provided with a ring 4, and the ring 4 is provided with a nylon band 5, which is convenient for hanging when the skipping rope is not in use, does not take up space, and is also easy to find.

The top of the handle 1 is provided with an inner convex ring 12, the end cover 2 is provided with an annular groove 11, the annular groove 11 matches the inner convex ring 12, the lower end of the annular groove 11 is provided with an outer convex ring 13, and the outer convex ring 13 The outer diameter is smaller than the inner diameter of the handle 1 and larger than the inner diameter of the inner convex ring 12, which is beneficial to prevent the end cap 2 from falling off.

The diameter of the small hole 14 is greater than the outer diameter of the rope 3 , which facilitates the passing of the rope 3 through the handle 1 .

The handle 1 and the end cap 2 are made of plastic, light in weight and easy to carry.

The utility model drives the worm 6 to rotate through the rotation of the end cover 2 relative to the handle 1, and drives the worm wheel 7 to rotate through the rotation of the worm 6. Since the worm wheel 7 and the take-up wheel 9 are fixedly installed on the worm wheel shaft 10, the worm wheel shaft 10 is on the worm wheel Driven by the rotation of 7, it also drives the rotation of the take-up reel 9, and the rope 3 fixed on the take-up reel 9 just follows the rotation of the take-up reel 9 to realize the function of winding or unwinding the rope 3, thus solving the problem well. Existing rope skipping at present has the problem that the length of its rope 3 is difficult to adjust; at the same time, due to the effect of the fixed shaft 8, it can better ensure that the worm gear shaft 10 can drive the worm wheel 7 to rotate smoothly, and it also effectively controls the axis of the worm screw 6. Limit and strengthen the role of stability; finally, because the worm gear mechanism has a self-locking effect, only the rotation of the worm screw 6 can drive the rotation of the worm wheel 7, and the worm wheel 7 cannot in turn drive the rotation of the worm screw 6. Therefore, when the length of the rope 3 is adjusted, Its length will not change during use, which is convenient for users to use the utility model product better.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed in the present utility model. Replacement should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
