AI Technical Summary
Traditional weightlifting benches are inconvenient to move and lack stability in scenarios requiring frequent movement, especially when the weightlifting bar is lowered with a large number of weight plates, posing a risk of tipping over.
The system employs a combination of support legs, gas springs, and shock-absorbing pads to form a triangular support. When the dynamic load is overloaded, the support legs rotate, the gas springs stretch, and the shock-absorbing pads rebound, enhancing stability and preventing tipping.
This improves the stability of the weightlifting bed, avoids the risk of tipping over, and reduces the space required and the complexity of moving it.

[0008] Gas spring: one end of the gas spring is hinged with the supporting leg, and the other end of the gas spring is hinged with the column provided with barbell stand of weight lifting bed, so that a triangle is formed between the supporting leg, gas spring and column, so that when a person exercises, if the weight lifting rod with a large number of weight lifting pieces is placed on the weight lifting rod support frame, and if the instantaneous dynamic load exceeds the maximum load of the structure of the weight lifting bed, the supporting leg will rotate backward, the gas spring will also lengthen accordingly, and the shock pad will rebound outward until it can withstand the instantaneous dynamic load, and the triangular structure will be stable, so as to avoid the risk of toppling of the weight lifting bed.
[0009] Further, the shock pad is a rubber shock pad, so the material has good anti-slip and shock absorption capacity, so this material is selected.
[0010] As a preferred, the thickness of the rubber shock pad is greater than 1cm, the inventor found that when the thickness of the rubber shock pad is greater than 1cm, the rubber shock pad can be in full surface contact with the ground through deformation when the support leg rotates backward, thereby further enhancing the anti-toppling effect, and as a further preferred, the thickness of the rubber shock pad is 1-3cm.
[0011] Further, the hinge part is a U-shaped plate, the bottom of the U-shaped plate is fixedly connected with one end of the support leg, and a through hole is arranged on the U-shaped plate and used for being hingedly connected with a hinge point on the stand column, so that the support leg can be hingedly connected with the stand column through the rotating shaft and can only rotate backward.
[0012] Further, one end of the gas spring is hingedly connected with the lower half of the stand column, and the other end of the gas spring is hingedly connected with the lower half of the support leg.
[0013] Further, the support leg and the gas spring are two groups, which are respectively arranged on the stand columns on two sides of the barbell stand.
[0014] Further, the stand column is inclined to the direction of the support leg, so that the stability of the weight lifting bed can be further improved.
[0015] As a preferred, the included angle between the stand column and the ground is 75-90°.
[0016] Compared with the prior art, the weight lifting bed using the utility model not only has high stability and is convenient to move, but also does not need to be additionally provided with a fixed frame with complex structure, so that the floor space occupied by the weight lifting bed can be reduced while the structural stability is greatly improved.
