Description

Technical Field

[0001] This utility model relates to the field of dumbbell support technology, and in particular to a multifunctional dumbbell support. Background Technology

[0002] Dumbbell racks are fitness equipment used to store dumbbells, primarily for use in homes and gyms. They can hold multiple pairs of dumbbells and optimize space layout. Traditional dumbbell racks are bulky and non-detachable. In today's era of online shopping, traditional dumbbell racks have the following drawbacks: their large size increases the packaging volume, raising transportation costs, and they are easily damaged during handling. Therefore, some detachable dumbbell racks have appeared on the market.

[0003] For example, the Chinese utility model patent "An Easy-to-Disassemble Dumbbell Rack" with patent authorization announcement number CN210021117U includes a base comprising two fixed base plates that are opposite to each other and spaced apart; and a storage assembly disposed between the two fixed base plates. The storage assembly includes two storage racks that are hinged to each other at their top and detachably fixed to the fixed base plates at their bottom. Each storage rack has at least two storage slots that extend diagonally downward from the outer edge of the storage rack into the interior of the storage rack and are connected to the outside.

[0004] In the above scheme, the spacing between adjacent storage slots is not adjustable. However, different dumbbells have different sizes of counterweights at both ends. When placing dumbbells of different weights, the larger size of the counterweights of adjacent dumbbells may cause interference and restriction when placing other dumbbells in the storage slots, resulting in the empty storage slots not being fully utilized and leading to low space utilization.

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0027] This embodiment mainly describes a multifunctional dumbbell stand, as follows:

[0028] like Figures 1 to 6As shown, a multifunctional dumbbell stand includes a base 1, two support plates 2 and at least two support platforms 3. The support platforms 3 are provided with placement slots 32. The base 1 is the foundation of the entire dumbbell stand, providing stability and support for the dumbbells. The two support plates 2 are fixedly connected to the base 1 by bolts or screws. The bolts or screws make the dumbbell stand detachable, which is convenient for transportation and storage. Each support platform 3 includes a connecting sleeve 31 that slides onto the support upright plate 2. The two support upright plates 2 have several vertically arranged fixing holes 21. The connecting sleeve 31 has a limiting member 4, which can cooperate with the fixing holes 21 at any height to fix the support platform 3 onto the support upright plate 2. The limiting member 4 includes a mounting base 41, an operating arm 42, a limiting post 43, and an elastic member. The mounting base 41 is fixed to the connecting sleeve 31, the operating arm 42 is hinged to the mounting base 41, the limiting post 43 is hinged to one end of the operating arm 42, and the elastic member is located on the side away from the limiting post 43. The connecting sleeve 31 has a through hole 311, and when the connecting sleeve 31 slides to any height of the fixing hole 21, the through hole 311 corresponds evenly to the fixing hole 21 at that location. The limiting post 43 slides through the through hole 311, passes through the connecting sleeve 31, and can extend into the fixing hole 21. The elastic element is located between the operating arm 42 and the connecting sleeve 31, and always provides an upward elastic force to the side of the operating arm 42 away from the limiting post 43, so that the limiting post 43 is inserted downward and locked in the fixing hole 21. When the end of the operating arm 42 away from the limiting post 43 is pressed, the limiting post 43 moves upward and disengages from the fixing hole 21. At this time, the support platform 3 is unlocked and can slide along the support plate 2. During the sliding process, the limiting post 43 is located in the through hole 311. When the sliding reaches a suitable height, the pressure on the operating arm 42 can be stopped. When the operating arm 42 loses pressure, the support platform 3 can be slightly adjusted so that the lower end of the limiting post 43 corresponds to the nearest fixing hole 21. The elastic element has an upward elastic force on the end of the operating arm 42 away from the limiting post 43. Under the action of the elastic element, the limiting post 43 is inserted downward into the fixing hole 21 to fix the support platform 3. By installing a connecting sleeve 31 on the support platform 3 and fitting it onto the support upright plate 2, and by installing a limiting member 4 on the connecting sleeve 31, the limiting member 4 cooperates with the fixing hole 21 to achieve quick locking and unlocking of the support platform 3. This facilitates adjustment of the position of the support platform 3, thereby adjusting the spacing between adjacent placement slots 32 in the vertical direction. The height of the placement slots 32 can be adjusted according to the size of the counterweights at both ends of the dumbbell, avoiding the problem of some placement slots 32 being unusable due to the large size of adjacent dumbbell counterweights, thus improving space utilization and flexibility. The elastic element design ensures the pressure of the limiting post 43 within the fixing hole 21, guaranteeing the stability of the support platform 3.

[0029] like Figure 6As shown, the distance from one end of the operating arm 42 connected to the limiting post 43 to its hinge point with the mounting base 41 is L1, and the distance from the end of the operating arm 42 away from the limiting post 43 to its hinge point with the mounting base 41 is L2, where L1 is less than L2. The operating arm 42 is hinged to the mounting base 41, forming a lever structure with the hinge point as the fulcrum. By setting L1 to be less than L2, it is easier and more flexible to press the operating arm 42.

[0030] like Figure 1 and Figure 2 As shown, each support plate 2 has two rows of fixing holes 21, which are vertically symmetrically arranged on both sides of the support plate 2. There are two limiting posts 43, and the operating arm 42 has two connecting arms 421. The two limiting posts 43 are hinged to the ends of the two connecting arms 421, and each limiting post 43 corresponds one-to-one with a fixing hole 21 at the same height. This design makes the support platform 3 more stable, and the symmetrically arranged fixing holes 21 and limiting posts 43 ensure the balance of the support platform 3 at different heights, improving the overall structural stability.

[0031] like Figure 5 , Figure 6 As shown, the operating arm 42 is provided with hinge shafts 5 that pass through the two connecting arms 421 in sequence, and the two ends of the hinge shafts 5 extend out of the operating arm 42. The mounting base 41 consists of two parallel mounting plates 411, and the operating arm 42 is hinged to the two mounting plates 411 of the mounting base 41 through the two ends of the hinge shafts 5. In order to provide more stable pressure to the two limiting posts 43 and improve the reliability of the overall structure, two elastic elements are designed, located between each connecting arm 421 and the connecting sleeve 31, and always providing an upward elastic force to the connecting arm 421 on the side away from the limiting post 43.

[0032] Specifically, the elastic element can be a return spring 44 or a torsion spring. When the elastic element is a return spring 44, the return spring 44 and the limiting post 43 are located on both sides of the hinge between the operating arm 42 and the mounting base 41, respectively. One end of the return spring 44 abuts against the lower surface of the operating arm 42, and the other end abuts against the upper surface of the connecting sleeve 31. When the elastic element is a torsion spring, the torsion spring is sleeved on the hinge shaft 5, and the two free ends of the torsion spring and the limiting post 43 are located on both sides of the hinge between the operating arm 42 and the mounting base 41, respectively. One free end of the torsion spring abuts against the lower surface of the operating arm 42, and the other free end abuts against the upper surface of the connecting sleeve 31. The design of the return spring 44 or the torsion spring allows the operating arm 42 to provide an upward elastic force to the end of the operating arm 42 away from the limiting post 43 after being pressed, so that the limiting post 43 is pressed into the fixing hole 21.

[0033] like Figure 1As shown, there are two placement slots 32. The operating arm 42 is located on the outer wall of the connecting sleeve 31 opposite to the two supporting uprights 2. This design places the operating arm 42 inside the two supporting uprights 2, greatly reducing the probability of accidentally pressing the operating arm 42 due to external factors. The outer wall of the connecting sleeve 31 on the opposite side of the two supporting uprights 2 has an outwardly extending extension plate 33. The two placement slots 32 are respectively fixed on the two extension plates 33. The placement slots 32 make the dumbbells more securely stored. At the same time, the extension plates 33 are located on the opposite side of the two supporting uprights 2, and the placement slots 32 are installed on the extension plates 33, making the placement slots 32 exposed and convenient for placing dumbbells.

[0034] like Figure 6 As shown, the placement slot 32 consists of a rear arc block 321 and a front arc block 322. Here, the rear arc block 321 refers to the arc block closest to the supporting upright plate 2, and the front arc block 322 refers to the arc block farther away from the supporting upright plate 2. The bottom of the rear arc block 321 is provided with a support seat 3211 extending towards the front arc block 322. The support seat 3211 is provided with a slide rail 3212. The rear arc block 321 has a sliding hole 3 that passes through the extension plate 33 from its front end. 213. The bottom of the front arc block 322 is provided with a slider 3221 that mates with the slide rail 3212. One end of the front arc block 322 near the rear arc block 321 is provided with a slide rod 3222 that passes through the slide hole 3213. The part of the slide rod 3222 that extends out of the extension plate 33 is machined with a threaded section 3223. A compression spring 6 and a nut 7 are fitted on the threaded section 3223. One end of the compression spring 6 abuts against the back side of the extension plate 33, and the other end abuts against the nut 7. Through the design of the slide rail 3212 and the slider 3221, the front arc block 322 can slide on the slide rail 3212 to change the width of the storage slot, so that the placement slot 32 can accommodate dumbbells with different sized handles. At the same time, the design of the compression spring 6 and the nut 7 provides a clamping force for the front arc block 322, so that the placement slot 32 can clamp the dumbbell handles placed in the placement slot 32, ensuring the stability of the placement slot 32 after adjustment and improving the flexibility and reliability of the overall structure.

[0035] like Figure 1 As shown, two storage plates 8 are bolted between the two supporting uprights 2. These storage plates 8 are used to store dumbbell components, such as counterweights. Upward-folding baffles 9 are provided on both sides of the storage plates 8 to prevent items from falling out. The storage plates 8 are located at the top and bottom of the two supporting uprights 2. The storage plates 8 enhance the dumbbell rack's storage capacity, and the bolted fixing method makes installation and removal of the storage plates 8 easier, improving the overall practicality of the structure.

[0036] Specifically, the support platform 3 is located between the two storage plates 8. This design avoids the support platform 3 from sliding and makes its position more reasonable. At the same time, the design of the storage plates 8 makes the dumbbell rack more functional for storage, improving the overall practicality and space utilization of the structure.

[0037] In use, press the end of the operating arm 42 away from the limiting post 43 to make the limiting post 43 move upward and disengage from the fixing hole 21. The support platform 3 can be unlocked and slide along the support plate 2. When the sliding support platform 3 reaches the target height, release the operating arm 42. Under the elastic force of the elastic element, the operating arm 42 will automatically press the limiting post 43 into the fixing hole 21 at the corresponding height to complete the locking.
