Description

Technical Field

[0001] This utility model relates to the field of dumbbell rack technology, and in particular to a structure for increasing the stability of a dumbbell rack. Background Technology

[0002] A dumbbell rack is a piece of equipment used to store and hold dumbbells, primarily for use in homes or gyms, to facilitate the management and use of dumbbells.

[0003] Most dumbbell racks are made of steel to ensure the rack's strength in supporting the dumbbells. However, this also results in excessive weight, making them inconvenient to move. Therefore, existing dumbbell racks often have guide wheels at the bottom. However, these wheels can cause the rack to slip and become unstable when the dumbbells are placed back on the rack due to the impact of the dumbbells' weight. To address this issue, we propose a structure to increase the stability of the dumbbell rack. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a structure that increases the stability of a dumbbell rack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a structure for increasing the stability of a dumbbell rack is designed, including a horizontal plate, with support frames vertically installed at both ends of the horizontal plate, and casters installed at both ends of the bottom of the support frames.

[0006] A shelf is provided on one side of the horizontal plate, and a first strip plate is installed on the other side of the horizontal plate. The first strip plate has at least two first through holes arranged at intervals. A second strip plate is provided parallel to the first strip plate below it. The second strip plate has a second through hole that is coaxial with the first through hole. A connecting shaft is installed in the second through hole. The top of the connecting shaft passes through the first through hole, and a counterweight is installed at the bottom of the connecting shaft.

[0007] A limiting groove is formed inside the second through hole, the limiting groove passes through the second strip plate, and a limiting block is installed on the outer wall of the connecting shaft. The limiting block corresponds to the limiting groove, and the length of the limiting block is less than the distance between the second strip plate and the first strip plate.

[0008] Preferably, a cover is provided above the caster wheel, and the cover is fixed to the support frame.

[0009] Preferably, anti-slip pads are installed on the bottom of the counterweight.

[0010] Preferably, a handle is installed on the top of the connecting shaft, and the handle is an "L" shaped rod.

[0011] Preferably, the horizontal plate is inclined, the placement frame includes multiple support plates, the multiple support plates are fixed on the horizontal plate along the inclined direction of the horizontal plate, and the support plates are perpendicular to the horizontal plate, and multiple slots are arranged at intervals on the support plates.

[0012] Preferably, columnar buffer blocks are installed on both sides of the slot, a buffer pad is provided on one side of the bearing plate, and the buffer pad is fixed to the horizontal plate, and both the buffer pad and the buffer block are made of elastic rubber.

[0013] Preferably, multiple reinforcing plates are installed at the bottom of the support plate, the reinforcing plates are located between two adjacent slots, one side of the reinforcing plate is fixed to the horizontal plate, and the other side of the reinforcing plate is fixed to the support plate.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1. The structure that increases the stability of the dumbbell rack allows the limiting block to be placed in the limiting groove or on the second strip plate by sliding and rotating the connecting shaft in the through hole. This allows the counterweight to either fall to the ground to increase the contact between the dumbbell rack and the ground and improve the stability of the dumbbell rack, or lift the counterweight without affecting the dumbbell rack's ability to be moved by the casters.

[0016] 2. The structure that increases the stability of the dumbbell rack uses an inclined horizontal plate and a support plate that is perpendicular to the horizontal plate. The side of the support plate away from the horizontal plate is tilted upwards. When the dumbbell is placed in the slot, one end of the dumbbell can be placed against the horizontal plate, ensuring the stability of the dumbbell when it is placed. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A structure for increasing the stability of a dumbbell rack includes a horizontal plate 1, with support frames 2 vertically installed at both ends of the horizontal plate 1, and casters 3 installed at both ends of the bottom of the support frames 2 to facilitate the movement and transport of the dumbbell rack; a cover 4 is provided above the casters 3, and the cover 4 is fixed on the support frame 2 to cover and protect the casters 3, preventing heavy objects from falling on the casters 3 and causing damage to the casters 3.

[0024] A shelf is provided on one side of the horizontal plate 1, wherein, for example... Figure 1 and Figure 2 As shown, the horizontal plate 1 is inclined, and the placement rack includes multiple support plates 5. The multiple support plates 5 are fixed on the horizontal plate 1 along the inclined direction of the horizontal plate 1, and the support plates 5 are perpendicular to the horizontal plate 1. Multiple slots 6 are arranged at intervals on the support plates 5, so that the side of the support plate 5 away from the horizontal plate 1 is inclined upward, so that when the dumbbell is placed in the slot 6, the end of the dumbbell can rest on the horizontal plate 1, thereby making the dumbbell placed in the slot 6 more stable.

[0025] Furthermore, cylindrical buffer blocks 7 are installed on both sides of the slot 6, and a buffer pad 8 is provided on one side of the bearing plate 5. The buffer pad 8 is fixed on the horizontal plate 1. Both the buffer pad 8 and the buffer block 7 are made of elastic rubber, which improves the stability of the dumbbell when it is placed in the slot 6. That is, when the dumbbell is placed in the slot 6, the weight of the dumbbell will cause the buffer block 7 and the buffer pad 8 to undergo elastic deformation, which can increase the contact surface to wrap the dumbbell and also buffer the dumbbell when it falls into the slot 6, so as to prevent damage to the bearing plate 5.

[0026] To further improve the support of the support plate 5 for the dumbbell, multiple reinforcing plates 9 are installed at the bottom of the support plate 5. The reinforcing plates 9 are located between two adjacent slots 6, and one side of the reinforcing plate 9 is fixed to the horizontal plate 1, while the other side of the reinforcing plate 9 is fixed to the support plate 5. This allows the reinforcing plates 9 to reinforce the connection between the support plate 5 and the horizontal plate 1, thereby improving the stress strength of the support plate 5.

[0027] like Figure 3 and Figure 4As shown, a first strip plate 10 is installed on the other side of the horizontal plate 1. At least two spaced-apart first through holes 11 are provided on the first strip plate 10. A second strip plate 12 is provided parallel to the first strip plate 10 below it. A second through hole 13, coaxially corresponding to the first through holes 11, is provided on the second strip plate 12. A connecting shaft 15 is installed inside the second through hole 13. The top of the connecting shaft 15 passes through the first through hole 11. A handle 16, which is an "L"-shaped rod, is installed on the top of the connecting shaft 15. A counterweight 17 is installed at the bottom of the connecting shaft 15, allowing the counterweight 17 to rest on the caster wheel 3. The weight block 17 is positioned on the ground, increasing the contact area between the dumbbell rack and the ground, thus improving the friction between them. To further enhance this effect, anti-slip pads are installed at the bottom of the weight block 17, ensuring the stability of the dumbbell rack. In actual use, the weight block 17 is a large metal block, increasing the overall weight of the dumbbell rack and the interaction between the weight block 17 and the ground, reducing the probability of accidental slippage. Moreover, the connecting shaft 15 passes through the two strip plates, which, together with the weight block 17, also reduces the probability of the dumbbell rack tipping backward when the horizontal plate 1 is under stress.

[0028] In use, a limiting groove 14 is provided inside the second through hole 13, the limiting groove 14 passes through the second strip plate 12, and a limiting block 18 is installed on the outer wall of the connecting shaft 15. The limiting block 18 corresponds to the limiting groove 14, and the length of the limiting block 18 is less than the distance between the second strip plate 12 and the first strip plate 10. When the dumbbell rack needs to be moved, a person can hold the handle 16 and lift the counterweight 17 until the limiting block 18 is disengaged from the limiting groove 14. Then, the handle 16 is rotated so that the limiting block 18 can be placed horizontally on the second strip plate 12, so that the counterweight 17 can be lifted off the ground and kept suspended and stable. At this time, the support frame 2 can be pushed to move the dumbbell rack to the desired position. Then, the handle 16 is lifted again and the connecting shaft 15 is rotated to rotate the limiting block 18 to the position corresponding to the limiting groove 14. Then, the connecting shaft 15 is lowered so that the counterweight 17 falls to the ground, so that the dumbbell rack can be stabilized on the ground.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
