[0019] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0020] The present utility model will be further described below with reference to the accompanying drawings.

[0021] As Figures 1-5 shown, a barbell placement rack that is convenient to move includes a chassis 1, an upper bracket 2, four universal wheels 3, two threaded rods 4, two bearings 5, two support plates 6, multiple guide rods 7 and an extension assembly.

[0022] Specifically, an upper bracket 2 is provided on the upper surface of the chassis 1, and four universal wheels 3 are evenly provided on the lower surface of the chassis 1. By providing four universal wheels 3, the device can be conveniently moved. Threaded holes are mirror - opened on the chassis 1, and a threaded rod 4 is thread - connected in each threaded hole. The bottom of the threaded rod 4 is connected to a bearing 5, and the bearing 5 is installed on the support plate 6. By rotating the threaded rod 4, the corresponding bearing 5 and support plate 6 can be driven to move linearly up and down along the direction of the guide rod 7, so that the support plate 6 is far from or close to the ground; multiple guide rods 7 are also connected to the support plate 6, and the multiple guide rods 7 pass through the chassis 1. An extension assembly for taking and placing barbell plates is also provided on the chassis 1.

[0023] Specifically, the stretching component includes a mounting bracket 8, two slide rails 9, four sliding plates 10, a motor 11, a gear 12, two racks 13, and two barbell plate brackets 14. The upper surface of the chassis 1 is connected to the mounting bracket 8. The upper surface of the mounting bracket 8 is mirror-connected with two slide rails 9. The slide rails 9 serve to support the sliding plates 10 and the barbell plate brackets 14. At the same time, the slide rails 9 can limit the movement direction of the sliding plates 10, such that the sliding plates 10 can only drive the two barbell plate brackets 14 to move relatively or away from each other. Each slide rail 9 is slidably connected with a corresponding sliding plate 10. A barbell plate bracket 14 is connected to two corresponding sliding plates 10. A rack 13 is provided on the lower surface of each barbell plate bracket 14. Both racks 13 are engaged with the gear 12. The gear 12 is connected to the output end of the motor 11. The fixed end of the motor 11 is connected to the mounting bracket 8.

[0024] Specifically, a plurality of hanging brackets 15 are evenly provided on the upper bracket 2. Each hanging bracket 15 is used to place a barbell; anti-slip patterns are provided in each hanging bracket 15. By setting the anti-slip patterns, the friction between the barbell bar and the corresponding hanging bracket 15 can be increased, improving the stability of the barbell placement. An anti-slip pad is provided on the lower surface of the support plate 6. The anti-slip pad can increase the friction between the support plate 6 and the ground, preventing the device from moving and improving the stability of the device itself; a handle 16 is provided on each threaded rod 4. The handle 16 can facilitate the rotation of the threaded rod 4; both the chassis 1 and the upper bracket 2 are made of stainless steel material. The stainless steel material has good strength and corrosion resistance, which can greatly extend the service life of the device.

[0025] Working principle: When the device needs to be moved, first rotate the handle 16. At this time, the threaded rod 4 rotates to drive the corresponding bearing 5 and the support plate 6 to move upward until the support plate 6 is away from the ground. Then, the device is pushed to a suitable position. Next, rotate the handle 16 in the reverse direction. At this time, the threaded rod 4 rotates, driving the corresponding bearing 5 and the support plate 6 to move downward until the support plate 6 is in close contact with the ground, and the device is fixed by relying on the friction between the support plate 6 and the ground;

[0026] When the barbell plates need to be replaced, turn on the motor 11. At this time, the motor 11 drives the gear 12 to rotate. Since the gear 12 meshes with the two racks 13, the gear 12 drives the two racks 13 to move away from each other. The two racks 13 drive the corresponding barbell plate brackets 14 to move away along the direction of the slide rails 9 until the two barbell plate brackets 14 are completely extended from the mounting bracket 8, which facilitates the exerciser to take and place the barbell plates. After using the barbell, place the barbell plates back into the corresponding barbell plate brackets 14, and then place the barbell on a suitable hanging bracket 15. Then, turn on the motor 11 again to reverse the motor 11, driving the two barbell plate brackets 14 back to the initial position, which can effectively save space.
