[0003] Current technology is inadequate: A barbell consists of a barbell bar, weight plates, and a clamp. Users hold the barbell bar for training. Different users have different hand sizes and need to hold barbell bars of different thicknesses to ensure a tight grip and improve comfort. However, most existing barbell bars are one-piece structures, which cannot be adjusted according to different users and have poor flexibility. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adaptive adjustable barbell to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive adjustable barbell, including a barbell mechanism, and further including a support mechanism and an adjustment mechanism. The side of the support mechanism is movably sleeved with the inner wall of the side of the barbell mechanism. The side of the adjustment mechanism is movably connected with the side of the barbell mechanism. The barbell mechanism includes a barbell bar, a limit ring is sleeved on the side of the barbell bar, a barbell plate is movably sleeved on the side of the barbell bar, and a fastening sleeve is threadedly connected to the side of the barbell bar. The support mechanism includes a bidirectional threaded shaft, the side of the bidirectional threaded shaft is movably sleeved with the inner wall of the side of the barbell bar, a threaded block is threadedly connected to the side of the bidirectional threaded shaft, and a support rod is movably connected to the top of the threaded block via a pin. A through groove is formed on the side of the barbell bar, the side of the through groove is movably connected to the side of the support rod, and a support plate is movably connected to the top of the support rod via a pin. The through groove is evenly distributed on the side of the barbell bar.

[0006] Furthermore, the threaded blocks on both sides are symmetrically distributed along the center of the bidirectional threaded shaft, and the threaded blocks are evenly distributed on the side of the bidirectional threaded shaft.

[0007] Furthermore, the top of the support plate has an arc-shaped structure, and the sides of the support plate have rounded corners.

[0008] Furthermore, an elastic telescopic sleeve is movably connected to the side of the support plate, and the surface of the elastic telescopic sleeve is frosted.

[0009] Furthermore, the barbell bar has a mounting groove on its side, the adjustment mechanism includes a knob, the side of the knob is movably connected to the side of the mounting groove, a connecting post is fixedly connected to the inner wall of the side of the knob, a limiting gear is fixedly connected to the side of the connecting post, a hexagonal locking block is fixedly connected to the side of the limiting gear, a toothed groove is formed on the side of the barbell bar corresponding to the position of the limiting gear, the side of the toothed groove meshes with the side of the limiting gear, and a hexagonal locking groove is formed on the side of the bidirectional threaded shaft, the side of the hexagonal locking groove meshes with the side of the hexagonal locking block.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model uses an adjustment mechanism to drive the bidirectional threaded shaft to rotate. The threaded shaft drives the threaded blocks on both sides to slide towards each other along the inner wall of the barbell bar. This causes the bottom end of the support rod to rotate along the side pin of the threaded block, and the top end of the support rod to rotate along the bottom pin of the support plate. This causes the surrounding support plates to move outwards from the barbell bar, opening the elastic telescopic sleeve and maintaining a suitable diameter, making it convenient for the operator to hold. This improves the flexibility of the equipment and the comfort of the user.

[0013] 2. This utility model allows the limiting gear plate to separate from the tooth groove by pulling the knob outward. Rotating the knob causes the hexagonal locking block and the hexagonal locking groove to mesh and drive the bidirectional threaded shaft to rotate, thereby adjusting the support mechanism. After adjustment, releasing the knob causes the tension spring to pull the knob, causing the limiting gear plate to automatically insert into the tooth groove. The engagement between the limiting gear plate and the tooth groove fixes the knob, thus securing the support mechanism. The operation is simple and improves work efficiency.

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adaptive adjustable barbell involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Reference Figures 1 to 6This utility model provides an adaptive adjustable barbell, including a barbell mechanism 1, a support mechanism 2, and an adjustment mechanism 3. The side of the support mechanism 2 is movably sleeved with the inner wall of the side of the barbell mechanism 1, and the side of the adjustment mechanism 3 is movably connected with the side of the barbell mechanism 1. The barbell mechanism 1 includes a barbell bar 101, a limit ring 104 sleeved on the side of the barbell bar 101, a barbell plate 103 movably sleeved on the side of the barbell bar 101, and a fastening sleeve 102 threadedly connected to the side of the barbell bar 101. The support mechanism 2 includes a bidirectional threaded shaft 201, the side of which is movably sleeved with the inner wall of the side of the barbell bar 101, and a threaded block 202 threadedly connected to the side of the bidirectional threaded shaft 201. The top of the threaded block 202 is movably connected to a support rod 204 via a pin. A through groove 106 is formed on the side of the barbell bar 101, and the side of the through groove 106 is movably connected to the side of the support rod 204. The top of the bar 204 is movably connected to the support plate 203 via a pin. The through grooves 106 are evenly distributed on the side of the barbell bar 101. During use, a suitable number of barbell plates 103 are selected and fitted onto both ends of the barbell bar 101. The fastening sleeve 102 is fitted onto the barbell bar 101 via threads and tightened, fixing the barbell plates 103 between the fastening sleeve 102 and the limiting ring 104. According to the usage requirements, rotating the adjustment mechanism 3 drives the bidirectional threaded shaft 201 to rotate. Through the threads, the threaded blocks 202 on both sides slide towards each other along the inner wall of the barbell bar 101, thereby causing the bottom end of the support rod 204 to rotate along the side pin of the threaded block 202, and the top end of the support rod 204 to rotate along the bottom pin of the support plate 203, causing the surrounding support plates 203 to move outwards from the barbell bar 101, maintaining a suitable distance between the support plates 203 and the barbell bar 101, and ensuring that the support mechanism 2 provides proper support. The user holds the support plate 203 for use.

[0018] Among them, the threaded blocks 202 on both sides are symmetrically distributed along the center of the bidirectional threaded shaft 201, and the threaded blocks 202 are evenly distributed on the side of the bidirectional threaded shaft 201.

[0019] The top of the support plate 203 is an arc-shaped structure, and the side of the support plate 203 is provided with a rounded corner 205. When the support plate 203 is in close contact with the side of the barbell bar 101, it forms a cylindrical contact, and the rounded corner 205 avoids jamming.

[0020] The support plate 203 is movably connected to an elastic telescopic sleeve 206. The surface of the elastic telescopic sleeve 206 is frosted to increase the friction between the user's hand and the support plate 203. When the support plate 203 moves, the elastic telescopic sleeve 206 always stays close to the side of the support plate 203, so that the elastic telescopic sleeve 206 maintains a cylindrical structure and is easy to hold.

[0021] The barbell bar 101 has a mounting groove 107 on its side. The adjustment mechanism 3 includes a knob 301, the side of which is movably connected to the side of the mounting groove 107. A connecting post 304 is fixedly connected to the inner wall of the side of the knob 301. A limiting gear 306 is fixedly connected to the side of the connecting post 304. A hexagonal locking block 302 is fixedly connected to the side of the limiting gear 306. A toothed groove 105 is formed on the side of the barbell bar 101 corresponding to the position of the limiting gear 306. The side of the toothed groove 105 meshes with the side of the limiting gear 306, forming a bidirectional thread. A hexagonal slot 207 is provided on the side of the shaft 201. The side of the hexagonal slot 207 meshes with the side of the hexagonal block 302. When the support mechanism 2 needs to be adjusted, pull the knob 301 outward to separate the limiting gear 306 from the tooth groove 105. Rotate the knob 301, and the hexagonal block 302 and the hexagonal slot 207 mesh with each other to drive the bidirectional threaded shaft 201 to rotate. After the adjustment is completed, push the knob 301 to insert the limiting gear 306 into the tooth groove 105 to fix the knob 301, thereby fixing the bidirectional threaded shaft 201.

[0022] The knob 301 has a mounting ring 305 movably sleeved on its inner side wall. A tension spring 303 is fixedly connected to the side of the mounting ring 305. The side of the tension spring 303 is fixedly connected to the side of the barbell bar 101. When the knob 301 is rotated, the mounting ring 305 rotates along the inner side wall of the knob 301 to prevent the tension spring 303 from deforming. After the knob 301 is released, the tension spring 303 pulls the knob 301 so that the limiting gear 306 automatically inserts into the tooth groove 105.

[0023] The side of the limiting toothed disc 306 is tapered, which makes it easy for the limiting toothed disc 306 to be inserted into the tooth groove 105. The side of the knob 301 is provided with anti-slip protrusions 307.

[0024] The working principle of this utility model is as follows: During use, select an appropriate number of barbell plates 103 and place them on both ends of the barbell bar 101. Secure the fastening sleeve 102 onto the barbell bar 101 using threads and tighten it, fixing the barbell plates 103 between the fastening sleeve 102 and the limiting ring 104. According to usage requirements, pull the knob 301 outwards to separate the limiting gear 306 from the tooth groove 105. Rotate the knob 301, causing the hexagonal locking block 302 to mesh with the hexagonal locking groove 207, thus rotating the bidirectional threaded shaft 201. This, in turn, causes the threaded blocks 202 on both sides to rotate along the inner wall of the barbell bar 101. The two sides slide towards each other, causing the bottom end of the support rod 204 to rotate along the side pin of the threaded block 202, and the top end of the support rod 204 to rotate along the bottom pin of the support plate 203, causing the surrounding support plates 203 to move outwards from the barbell bar 101, opening the elastic telescopic sleeve 206 and maintaining a suitable diameter for easy gripping by the operator. After adjustment, after releasing the knob 301, the tension spring 303 pulls the knob 301, causing the limiting gear 306 to automatically insert into the tooth groove 105. The knob 301 is fixed by the intermeshing of the limiting gear 306 and the tooth groove 105, thereby fixing the support plate 203.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
