[0001] This utility model relates to the field of fitness equipment, and in particular to a vibrating fitness bar with adjustable weight. Background Technology
[0002] Currently, there is a type of vibrating fitness bar on the market, which includes a vibrating bar body shaped like a spiral spring. The proximal end of the vibrating bar body has a handle, and the distal end is covered by a headgear. When in use, the user holds the handle and swings the vibrating fitness bar, causing it to vibrate elastically, thus achieving a workout effect. This type of vibrating fitness bar has the problem of non-adjustable weight at the distal end, resulting in only one weight setting for each model, which cannot meet the different strength training requirements of users. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable weight vibrating fitness bar to meet the user's training needs for different strengths.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] An adjustable weighted vibrating exercise bar includes a vibrating bar body, the vibrating bar body including a main body, a handheld end located at one end of the main body, and a weight end located at the other end of the main body; the main body is slidably fitted with at least one weight ring, the weight ring can slide towards the weight end to increase the weight of the weight end, and can slide towards the handheld end to decrease the weight of the weight end, and the weight ring is an elastic body, which is interference-fitted with the outer peripheral surface of the main body, and the weight ring will not slide on the main body when no external force is applied to the weight ring.
[0006] Furthermore, the counterweight end is provided with a first limiting stop for preventing the counterweight ring from coming off, and the handheld end is provided with a second limiting stop for preventing the counterweight ring from coming off.
[0007] Furthermore, the counterweight ring is a solid ring structure.
[0008] Furthermore, the counterweight ring has an outer ring surface and an inner ring surface arranged opposite to each other, wherein the outer ring surface is a convex arc surface structure that bulges outward from both ends of the axial direction, and the inner ring surface is a flat surface structure that is parallel to the axis of the main body.
[0009] Furthermore, the two axial ends of the inner ring surface are connected to the two axial ends of the outer ring surface by rounded chamfers.
[0010] Furthermore, the axial width of the counterweight ring is less than half the inner diameter of the counterweight ring.
[0011] Furthermore, the radial wall thickness of the counterweight ring is less than one-quarter of the inner diameter of the counterweight ring.
[0012] Furthermore, the counterweight end is covered with a protective sleeve, and the surface of the protective sleeve facing the main body forms the first limiting stop portion; the handheld end is covered with a grip sleeve, and the surface of the grip sleeve facing the main body forms the second limiting stop portion.
[0013] Furthermore, the vibrating rod body is generally shaped like a cylindrical helical spring, wherein the outer diameter of the handheld end is smaller than the outer diameter of the main body, the outer diameter of the counterweight end is equal to the outer diameter of the main body, and the pitch of both the handheld end and the counterweight end is smaller than the pitch of the main body.
[0014] Furthermore, the axial width of the counterweight ring is 0.5 to 1.5 times the pitch of the main body; the radial wall thickness of the counterweight ring is less than the pitch of the main body, but greater than the pitch of the handheld end and the counterweight end.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] First, this invention features at least one counterweight ring that slides onto the main body of the vibrating bar. This counterweight ring can slide towards the counterweight end to increase the weight of the counterweight end, or towards the handheld end to decrease the weight of the counterweight end. Since the force required for the human body to swing the vibrating bar will increase or decrease accordingly when the weight of the counterweight end increases or decreases, the purpose of adjusting the exercise force can be achieved, thereby meeting the user's exercise needs for different strengths.
[0017] Secondly, in this invention, the counterweight ring is an elastic body and is fitted onto the main body of the vibrator with an interference fit. This ensures that whether the counterweight ring is positioned near the counterweight end or near the hand-held end of the main body, it can be held in place by its own elastic clamping force, preventing it from sliding and affecting normal use. Since no additional locking device is needed for the counterweight ring, the structure is simple, operation is simplified, and manufacturing costs and difficulties are reduced.

[0023] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.
[0024] like Figures 1 to 5 As shown, the present invention discloses an adjustable weight vibrating fitness bar, comprising a vibrating bar body 1. The vibrating bar body 1 includes a main body 11, a handheld end 12 located at one end of the main body 11, and a weight end 13 located at the other end of the main body 11. At least one weight ring 2 is slidably fitted onto the main body 11. This weight ring 2 can slide towards the weight end 13 to increase the weight of the weight end 13, thereby increasing the force required for the user to swing the vibrating fitness bar during exercise; or it can slide towards the handheld end 12 to decrease the weight of the weight end 13, thereby reducing the force required for the user to swing the vibrating fitness bar during exercise. This achieves the purpose of adjusting the user's exercise strength. Furthermore, the counterweight ring 2 is an elastic body, for example, made of TPR material. It has an interference fit with the outer peripheral surface of the main body 11. When no external force is applied to the counterweight ring 2, it will not slide on the main body 11. In other words, whether the counterweight ring 2 is located near the counterweight end 13 or near the handheld end 12 of the main body 11, it can be held in that position by its own elastic clamping force and will not slide on its own, thus affecting normal use. When it is necessary to adjust the position of the counterweight ring 2, the user can apply a certain pushing force to make the counterweight ring 2 slide in the desired direction.
[0025] Furthermore, in order to prevent the counterweight ring 2 from accidentally falling off the vibrator body 1 during use, the counterweight end 13 is provided with a first limiting stop 301 to prevent the counterweight ring 2 from falling off, and the handheld end 12 is provided with a second limiting stop 401 to prevent the counterweight ring 2 from falling off.
[0026] In a preferred embodiment of this utility model, the counterweight ring 2 is a solid ring structure, which can increase its own weight.
[0027] In a preferred embodiment of this invention, the counterweight ring 2 has an outer ring surface 201 and an inner ring surface 202 disposed opposite to each other. The outer ring surface 201 is a convex arc surface structure that bulges radially outward from both axial ends, so that when two adjacent counterweight rings 2 overlap axially, the user's finger can enter the overlapping side of the counterweight rings 2 to push them. The inner ring surface 202 is a flat surface structure parallel to the axis of the main body 11, so that the counterweight ring 2 can slide smoothly on the main body 11 when the user applies force to push it. Furthermore, the axial ends of the inner ring surface 202 and the axial ends of the outer ring surface 201 can be connected by chamfered arcs 203.
[0028] In a preferred embodiment of this invention, the axial width W1 of the counterweight ring 2 is less than half the inner diameter D1 of the counterweight ring 2. The radial wall thickness T1 of the counterweight ring 2 is less than one-quarter of the inner diameter D1 of the counterweight ring 2.
[0029] In a preferred embodiment of this utility model, the counterweight end 13 is covered with a protective sleeve 3, and the surface of the protective sleeve 3 facing the main body 11 forms the first limiting stop 301. The handheld end 12 is covered with a grip sleeve 4, and the surface of the grip sleeve 4 facing the main body 11 forms the second limiting stop 401.
[0030] In a preferred embodiment of this utility model, the vibrating rod body 1 is in the shape of a cylindrical helical spring, wherein the outer diameter of the handheld end 12 is smaller than the outer diameter of the main body 11, the outer diameter of the counterweight end 13 is equal to the outer diameter of the main body 11, and the pitch of both the handheld end 12 and the counterweight end 13 is smaller than the pitch of the main body 11.
[0031] In a preferred embodiment of this invention, the axial width W1 of the counterweight ring 2 is 0.5 to 1.5 times the pitch of the main body 11. The radial wall thickness T1 of the counterweight ring 2 is less than the pitch of the main body 11, but greater than the pitch of the handheld end 12 and the counterweight end 13.
[0032] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
