[0001] The invention relates to the technical field of sports training, in particular to a modular barbell rack for sports training. Background Art

[0002] With the continuous progress and development of today's society, people's living standards are also constantly improving. People pay more and more attention to the improvement of their personal physical fitness. Physical exercise is increasingly valued by people, and sports equipment has also become more diverse. For sports, the use of barbells is very common. Barbells are a very common fitness equipment and can be seen everywhere in the gym. Barbells are used in conjunction with barbell racks. The combination of barbells and barbell racks can exercise the muscles of the shoulders, back, arms and chest. It also has the effects of delaying muscle aging, increasing bone density and preventing osteoporosis. It can improve endocrine and improve body coordination. It is one of the sports that men and women who want to exercise can engage in.

[0003] The traditional barbell rack places the barbell directly on the ground when people are doing bench press training. After using the barbell for a long time, the barbell is prone to fall due to hand exhaustion or hand slippage, causing the user to be injured or causing damage to the equipment, affecting the safety of the barbell rack.

[0004] Patent document with announcement number CN201840820U discloses a multifunctional horizontal weightlifting rack, including a frame body, on which a bed plate, a barbell rack and a protection rack are arranged. Existing barbell racks are provided with a protection rack to prevent injuries to personnel or equipment, but when a barbell falls onto the protection rack, it will affect the center of gravity of the barbell rack. Long-term use will not only easily affect the supporting and protective function of the barbell rack, but also cause secondary injuries to the user. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to prevent the safety of the barbell rack from being affected when the barbell falls.

[0006] The present invention solves the above-mentioned technical problems through the following technical means: a modular barbell rack for sports training, comprising a base, a buffer assembly, a center of gravity adjustment assembly, a barbell support assembly and a lying board; the buffer assembly, the center of gravity adjustment assembly and the barbell support assembly are all arranged on the base; two buffer assemblies are provided, and the lying board is arranged between the two buffer assemblies; the buffer assembly is arranged in linkage with the center of gravity adjustment assembly; the use height of the buffer assembly can be adjusted.

[0007] The buffer component can support the barbell to prevent the barbell from falling due to hand exhaustion or hand slippage after the user uses the barbell for a long time, thereby avoiding affecting the safety of the user; when the barbell falls on the buffer component, the center of gravity of the barbell rack can be adjusted through the linked center of gravity adjustment component, thereby avoiding affecting the safety of the barbell rack; the use height of the buffer component is adjustable, which is convenient for use by people with different needs and improves flexibility.

[0008] Preferably, the buffer assembly includes a supporting mechanism, a mounting seat, an extrusion plate, a buffer damping spring, a connecting block and a tray. The mounting seat is fixedly connected to the supporting mechanism, the extrusion plate and the mounting seat slide up and down, the two ends of the buffer damping spring are respectively fixedly connected to the extrusion plate and the mounting seat, and the extrusion plate is fixedly connected to the tray through the connecting block.

[0009] When the barbell falls on the tray, the tray will be squeezed by the impact force, and the tray drives the squeezing plate to move downward through the connecting block. At this time, the impact force is buffered by the buffer damping spring, which avoids affecting the service life of the barbell rack. At the same time, it reduces the noise generated when the barbell falls, preventing secondary fright to the user.

[0010] Preferably, two center of gravity adjustment components are provided, and each buffer component is linked to a center of gravity adjustment component; the center of gravity adjustment mechanism includes an elastic liquid sac, a water pipe, a shrinkage liquid sac, a sliding plate and a counterweight; the elastic liquid sac is located below the extrusion plate, and is fixedly connected to the extrusion plate and the mounting seat; the elastic liquid sac is connected to the shrinkage liquid sac through the water pipe; the shrinkage liquid sac is arranged on the base, and the side of the shrinkage liquid sac close to the buffer component is fixedly connected to the base, and the side away from the buffer component is fixedly connected with a counterweight through a sliding plate, and the counterweight is slidably fitted on the base.

[0011] When the extrusion plate moves downward, it will squeeze the elastic sac, and the water inside the elastic sac will be transported to the inside of the contraction sac through the water pipe, causing it to expand, and then the contraction sac will drive the counterweight to move along the slide rail to the side away from the buffer assembly, thereby increasing the center of gravity of the base away from the buffer assembly. When the barbell falls from a higher height, the greater the impact force it generates, the greater the distance the extrusion plate moves downward, and at the same time, the greater the extrusion force on the buffer damping spring and the elastic sac, so that more water is transported to the inside of the contraction sac through the water pipe from the elastic sac, and then the contraction sac drives the counterweight to move a greater distance, and the force of adjusting the center of gravity of the barbell rack is greater. When the force of the barbell is balanced on the tray, the buffer damping spring will drive the extrusion plate to move upward, and at this time the elastic sac will extract the water inside the contraction sac through the water pipe. The contraction sac will drive the counterweight to move to the side close to the buffer assembly under the contraction characteristics, which is convenient for automatically adjusting the center of gravity of the barbell rack, thereby improving the applicability of the barbell rack.

[0014] Preferably, the supporting mechanism further comprises ribs, and the two sides of the adjusting block are respectively fixedly connected with the ribs, and the mounting seat is fixedly connected to the adjusting block and the ribs on both sides thereof.

[0015] Preferably, the buffer assembly further includes a second connecting plate, and the first support column is fixedly connected to the barbell support assembly via the second connecting plate.

[0016] Preferably, two barbell support assemblies are provided, and the use height of the barbell support assemblies is adjustable.

[0017] Preferably, the barbell support assembly includes a second pillar, a lead screw, a threaded sleeve, a barbell rack, a first bevel gear, a second bevel gear, a rotating shaft and a rotating handle; the second pillar is fixedly connected to the base, and the lead screw is rotatably connected to the second pillar; the threaded sleeve and the second pillar are slidably matched along the lifting direction and are threadedly connected to the lead screw, and the barbell rack is fixedly connected to the threaded sleeve; the first bevel gear fixed sleeve is arranged on the outside of the lead screw, the second bevel gear fixed sleeve is arranged on the outside of the rotating shaft, and the second bevel gear is meshed with the first bevel gear; the rotating shaft is rotatably connected to the second pillar, and the rotating handle is fixedly connected to the rotating shaft.
