Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a barbell plate rack. Background Technology

[0002] A barbell plate rack is a device used to hang barbell plates, which can store scattered barbell plates to keep the training area tidy.

[0003] For example, Chinese patent document CN209734924U discloses a barbell plate holder with a locking structure to prevent it from falling off. It includes a main support and multiple barbell plate holders mounted on the main support. The main support includes three arc-shaped frames, the tops of which are fixedly connected together by a fixing block. Each of the three arc-shaped frames has a circular base at its bottom. A barbell plate holder is mounted above the fixing block. The barbell plate holder is cylindrical in shape. Multiple barbell plate holders are distributed sequentially along the arc-shaped frame from top to bottom. The multiple barbell plate holders on each arc-shaped frame are inclined upwards outwards from the arc-shaped frame and are parallel to each other. A locking structure is provided at the end of each barbell plate holder.

[0004] In the above technical solution, the locking structure provided at the end of the weight plate bracket can prevent the weight plate from falling off when it is mounted on the weight plate bracket.

[0005] However, in practical use, it was found that the number of weight plates that can be hung depends mainly on the length of the mounting bar (weight plate bracket), and in the above solution, the length of the mounting bar is constant. If there are many weight plates, the mounting bar may not be long enough to hang all of them. If there are few weight plates, part of the mounting bar may not be used effectively. Therefore, there are certain limitations in terms of flexibility in use. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a barbell plate rack that can adjust the length of the hanging bar to adapt to different usage scenarios and improve the flexibility of use.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment discloses a barbell plate holder, including support legs 1. Preferably, there are three support legs 1 evenly distributed circumferentially to form a stable triangular support structure. Each support leg 1 has a hanging rod 2 fixed to its upper part. The hanging rod 2 includes a fixed part 21 and a movable part 22. One end of the fixed part 21 is welded or bolted to the support leg 1, and the other end extends outward and is machined with external threads. The movable part 22 is a hollow tubular structure with internal threads matching the external threads on its inner wall. By rotating the movable part 22, it can be moved axially along the fixed part 21, thereby adjusting the overall length of the hanging rod 2 to accommodate barbell plates of different thicknesses and numbers. Furthermore, the locking force generated during the threaded connection ensures the overall stability of the hanging rod 2.

[0024] Example 2

[0025] like Figures 2 to 5As shown, the difference in this embodiment is that the bottom of the support leg 1 is provided with a horizontally outwardly extending mounting leg 3 to expand the support area, ensuring that the center of gravity of the hanging rod 2 falls into the support area, thereby improving the overall stability. Furthermore, the mounting leg 3 allows for the mounting of the support rod 4, which consists of a connecting part 41 and a telescopic part 42. The support rod 4 supports the hanging rod 2 to ensure stability when the hanging rod 2 is loaded with barbell plates. Specifically, a mounting base 5 is fixed to the upper surface of the mounting leg 3. A rotatable shaft 6 is mounted inside the mounting base 5 via a bearing. One end of the connecting part 41 is sleeved and fixed to the outer circumference of the shaft 6, allowing the support rod 4 to rotate around the shaft 6, facilitating contact between the support rod 4 and the moving part 22 at different axial positions. The telescopic part 42 is embedded in a connecting groove inside the connecting part 41 and can slide axially along the connecting groove. The end of the telescopic part 42 located away from the connecting part 41 extends as a support end below the moving part 22 of the hanging rod 2. A spring 7 is provided in the connecting groove. One end of the spring 7 is fixed to the bottom of the connecting groove, and the other end is fixed to the end of the telescopic part 42. The elastic force of the spring 7 pushes the telescopic part 42 to extend outward, so that the support end always abuts against the lower part 22 of the hanging rod 2, providing stable support for the hanging rod 2 and preventing the hanging rod 2 from deforming due to load. In addition, the length of the support rod 4 can be adjusted by the compression of the spring 7. When the moving part 22 moves by different lengths, the support rod 4 can provide stable support for the hanging rod 2.

[0026] Furthermore, to ensure the stability of the support rod 4 supporting the mounting rod 2, multiple inwardly recessed coupling grooves 221 are evenly formed along the circumference of the outer surface of the moving part 22, and a coupling part 421 matching the shape of the coupling groove 221 is provided at the top of the support end. When the moving part 22 rotates to the target length, the support rod 4 is pressed down to make the coupling part 421 embed into the corresponding coupling groove 221, and the friction between the contact surfaces of the two restricts the accidental movement of the moving part 22. In addition, a connecting seat 10 is fixed on one side of the mounting base 5, and one end of the rotating shaft 6 extends into the connecting seat 10 to form a locking end. A threaded hole is formed on the side wall of the connecting seat 10, and a locking bolt 8 is connected in the threaded hole. After the locking bolt 8 is screwed into the threaded hole, its end abuts perpendicularly against the locking end surface of the rotating shaft 6. By tightening the locking bolt 8, the rotational resistance of the rotating shaft 6 can be increased, thereby fixing the angle of the support rod 4 to ensure the stability of the support rod 4 supporting the mounting rod 2; after loosening the bolt, the support position of the support rod 4 can be freely adjusted.

[0027] To further enhance structural strength, multiple reinforcing rods 9 are connected between the inner sides of each mounting leg 3. The reinforcing rods 9 are arranged in a triangular pattern to connect each mounting leg 3, thereby effectively dispersing load stress and preventing the mounting leg 3 from deforming under stress.

[0028] The usage process of this embodiment is as follows:

[0029] Depending on the thickness and number of weight plates to be mounted, the mounting rod 2 is adjusted to a suitable length by rotating the moving part 22. Then, the weight plates are sequentially inserted onto the mounting rod 2. After mounting, the coupling part 421 is pressed into the corresponding coupling groove 221 by pressing down the telescopic part 42. The support rod 4 contacts the unloaded portion of the moving part 22 to support the mounting rod 2, ensuring its stability during prolonged weight plate mounting. When the weight plate rack needs to be moved, the mounting rod 2 can be adjusted to its shortest length by rotating the moving part 22, thus reducing space occupancy.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
