Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, and in particular to a fitness bar. Background Technology
[0002] To improve their physical fitness, more and more people are joining the fitness movement, and fitness equipment has become a helpful tool for exercise. However, most bar-shaped fitness equipment on the market does not provide effective workouts. For example, Chinese utility model patent CN220513340U discloses a fitness bar that includes an elastic bar, a grip, and a counterweight. The elastic bar has a hollow cavity inside, and the grip is detachably mounted on the end of the elastic bar. Specifically, the grip includes a hollow grip sleeve, which is threaded to the end of the elastic bar. The counterweight is detachably mounted on the side of the elastic bar away from the grip to cause the elastic bar to bend under force.
[0003] This type of fitness bar has the following drawbacks: First, adjusting the weight of the counterweights to suit the needs of different users will result in an imbalance of weight at both ends of the fitness bar, which will accelerate the wear and tear on the elastic bar over time; second, the counterweights on the elastic bar need to be disassembled and reassembled during exercise, which is inconvenient to use; third, the grip is directly threaded to the end of the elastic bar, which makes it unsuitable to use soft materials for the grip, thus affecting the comfort of holding and the user experience. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fitness bar that is easy to use and has a simple structure.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A fitness bar includes a bar body, a handle, and a limiting sleeve. The bar body is a cylindrical helical spring tube of a certain length, comprising a main body and a first end portion that tapers outward from one end of the main body. The handle is fitted onto the inner portion of the first end portion. The limiting sleeve has a threaded connection hole inside that matches the outer portion of the first end portion. The limiting sleeve is threadedly connected to the outer portion of the first end portion through the threaded connection hole and stops the outer end of the handle, preventing the handle from slipping off the first end portion. When the handle is gripped and swung or shaken, the bar body vibrates accordingly.
[0007] Furthermore, a first transition portion is provided between the main body and the first end portion, which narrows from the main body towards the first end portion.
[0008] Furthermore, the handle includes a stop sleeve fitted over the first transition portion and a hand grip fitted over the first end portion, with the outer portion of the first end portion exposed outside the hand grip.
[0009] Furthermore, a threaded connection portion is formed on the outer peripheral surface of the outer portion of the first end, and the limiting sleeve is threadedly connected to the threaded connection portion through the threaded connection hole.
[0010] Furthermore, the length of the first end portion is less than the length of the main body portion, and the two adjacent spring coils at the first end portion are in contact with each other, or the pitch between the two adjacent spring coils at the first end portion is less than 2mm.
[0011] Furthermore, the rod body also includes a second end portion formed by tapering outward from the other end of the main body portion. A second transition portion is provided between the main body portion and the second end portion, which tapes outward from the main body portion towards the second end portion. The length of the main body portion is greater than the sum of the lengths of the first end portion and the second end portion. A soft rubber cap is fitted over the outer portion of the second end portion. The two adjacent spring coils of the second end portion are in contact with each other, or the pitch between the two adjacent spring coils of the second end portion is less than 2 mm.
[0012] A fitness bar includes a bar body, a handle, and a limiting sleeve. The bar body is a cylindrical helical spring tube of a certain length, comprising a central main body, a first end, and a second end. The first end is formed by narrowing outward from one end of the central main body, and the second end is located at the other end of the central main body. The handle is fitted onto the inner part of the first end. The limiting sleeve has a threaded connection hole inside that matches the outer part of the first end. The limiting sleeve is threadedly connected to the outer part of the first end through the threaded connection hole and stops the outer end of the handle to prevent the handle from coming off the first end. When the handle is gripped and swung or shaken, the bar body vibrates accordingly.
[0013] Furthermore, a first transition portion with a reduced diameter from the intermediate main body portion toward the first end portion is provided between the intermediate main body portion and the first end portion. The handle includes a stop sleeve that is fitted onto the first transition portion and a hand sleeve that is fitted onto the first end portion. The outer portion of the first end portion is exposed outside the hand sleeve, and the outer peripheral surface of the outer portion of the first end portion forms a threaded connection portion. The limiting sleeve is threadedly connected to the threaded connection portion through the threaded connection hole.
[0014] Furthermore, the length of the first end portion is less than the length of the intermediate main body portion, and the two adjacent spring coils at the first end portion are in contact with each other, or the pitch between the two adjacent spring coils at the first end portion is less than 2mm.
[0015] Furthermore, the second end is formed by the outward reduction of the diameter of the other end of the intermediate main body. A second transition portion is provided between the intermediate main body and the second end, which is reduced in diameter from the intermediate main body to the second end. The length of the intermediate main body is greater than the sum of the lengths of the first end and the second end. A soft rubber cap is fitted over the outer part of the second end. The two adjacent spring coils of the second end are in contact with each other, or the pitch between the two adjacent spring coils of the second end is less than 2 mm.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] First, the main body of this utility model is a cylindrical helical spring tube, including a main body with a larger diameter and a first end with a smaller diameter located at one end of the main body. The handle is sleeved on the first end. Since the diameter of the first end is smaller than the diameter of the main body, the elastic vibration capability of the main body relative to the human hand gripping part composed of the first end and the handle can be increased during exercise, thereby improving the exercise effect.
[0018] Secondly, a handle is provided on the inner side of the first end. A limiting sleeve is threadedly connected to the outer part of the first end through a threaded connection hole, and stops the outer end of the handle to prevent it from coming off the first end. In this way, since the handle is only slipped on the bar body and does not need to be threaded to the handle, the handle can be made of soft material, which makes it more comfortable to hold the fitness bar during exercise and provides a better user experience.
