Description

Technical Field

[0001] This utility model belongs to the field of dumbbell rack technology, and in particular relates to a dumbbell rack with adjustable intervals. Background Technology

[0002] Dumbbells are a simple piece of equipment used for muscle strength training. They are primarily made of cast iron, sometimes with a rubber coating. Their purpose is for muscle strength training and compound muscle movement exercises. Patients with low muscle strength due to paralysis, pain, or prolonged inactivity can use dumbbells to perform active resistance exercises and train their muscle strength.

[0003] For example, patent CN214913234U discloses an adjustable dumbbell rack, including a dumbbell rack base. The base has internal fixing holes with threaded bolts connected to the inner walls. An adjustable upright square tube is fixedly mounted on the top of the base. Fixed connecting blocks overlap the front and back of the upright square tube. A stabilizing hole with a slanted quadrilateral cross-section is formed inside the upright square tube. Dumbbell brackets are fitted onto the outer surface of the upright square tube. This adjustable dumbbell rack allows for convenient adjustment of the dumbbell brackets' position on the adjusting upright square tube by placing the dumbbell brackets on top of the fixed insert blocks, thereby adjusting the spacing between the dumbbells. This achieves convenient adjustment of the dumbbell rack spacing, solving the problem of inconvenient storage caused by fixed dumbbell rack spacing mentioned in the background art.

[0004] Existing adjustable-space dumbbell racks often suffer from dumbbell slippage due to their weight. Therefore, we propose an adjustable-space dumbbell rack. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an adjustable dumbbell rack to prevent dumbbells from slipping off when placed in the rack.

[0006] In view of this, the present invention provides an adjustable dumbbell rack, including a base, with brackets fixedly connected to both ends of the base, an adjusting seat slidably connected to the inner wall of the brackets, a spring fixedly connected to the inner wall of the adjusting seat, a working frame fixedly connected to one end of the spring, a pressure rod fixedly connected to one end of the working frame, guide grooves provided at both ends of the outer wall of the working frame, guide posts movably connected within the guide grooves, telescopic posts fixedly connected to the outer wall of the guide posts, an adjusting hole provided at the connection between the brackets and the telescopic posts, a stabilizing frame fixedly connected to the outer wall of the adjusting seat, and a placement plate provided on the outer wall of the stabilizing frame.

[0007] Based on the above structure, the user drives the adjustment seat to slide along the outer wall of the bracket. When the adjustment seat slides to the appropriate position, the spring drives the work frame to slide through its own elastic force. The work frame slides through the guide groove, which drives the telescopic column at one end of the guide column to slide horizontally along the inner wall of the adjustment seat, so that the telescopic column slides to fit into the adjustment hole, thereby realizing the adjustment operation of the interval between the adjustment seats, which is convenient for placing dumbbells of different sizes.

[0008] Preferably, the guide groove is inclined. In this embodiment, it facilitates the sliding of the work frame through the guide groove, which drives the telescopic column at one end of the guide column to slide horizontally along the inner wall of the adjusting seat, so that the telescopic column slides to engage with the adjusting hole, thereby realizing the adjustment operation of the interval between the adjusting seats and the sliding operation of the telescopic column.

[0009] Preferably, the adjustment holes are equidistantly distributed along the outer wall of the bracket. In this embodiment, the equidistantly distributed adjustment holes facilitate the adjustment of the interval between the adjustment seats.

[0010] Preferably, the top of the placement plate is provided with an arc-shaped groove. In this embodiment, the groove at the top of the placement plate helps to improve the stability of the dumbbell placement and prevent the dumbbell from falling off.

[0011] Preferably, a screw is provided at the top of the stabilizing frame, and a lifting block is threadedly connected to the outer wall of the screw. A connecting rod is screwed to both ends of the lifting block. A stabilizing seat that is fixedly connected to the side wall of the placement plate is screwed to one end of the connecting rod. A limiting plate that is slidably connected to the side wall of the placement plate is fixedly connected to the outer wall of the stabilizing frame. In this embodiment, the lifting block drives the placement plate on the outer wall of the stabilizing seat to slide along the outer wall of the limiting plate through the connecting rod, thereby realizing the adjustment operation of the spacing between the placement plates, which is beneficial to improving the stability of placing dumbbells.

[0012] Preferably, the placement plate forms a sliding structure with the limiting plate through the lifting block and the connecting rod. In this embodiment, the lifting block drives the placement plate on the outer wall of the stabilizing seat to slide along the outer wall of the limiting plate through the connecting rod, thereby realizing the sliding operation of the placement plate.

[0013] Preferably, the limiting plate has a "T" shaped cross-section. In this embodiment, by setting a limiting plate with a "T" shaped cross-section, the placement plate is prevented from falling off after long-term use.

[0014] The beneficial effects of this utility model are:

[0015] 1. This adjustable dumbbell rack features telescopic columns and adjustment holes. The user slides the adjustment seat along the outer wall of the support. When the adjustment seat slides to the appropriate position, the spring drives the work frame to slide through its own elasticity. The work frame slides through the guide groove, causing the telescopic column at one end of the guide column to slide horizontally along the inner wall of the adjustment seat. This allows the telescopic column to slide until it engages with the adjustment hole, thus enabling the adjustment of the spacing between the adjustment seats and facilitating the placement of dumbbells of different sizes.

[0016] 2. This adjustable dumbbell rack, by setting up placement plates, has a screw rotating to drive the lifting block to slide vertically. The lifting block, through a connecting rod, drives the placement plate on the outer wall of the stabilizing seat to slide along the outer wall of the limiting plate, thereby realizing the adjustment of the spacing between the placement plates, which helps to improve the stability of placing dumbbells.

A stabilizing frame 11 is fixedly connected to the outer wall of the adjustment seat 3, and a placement plate 12 is provided on the outer wall of the stabilizing frame 11.

[0026] Based on the above structure, the user drives the adjustment seat 3 to slide along the outer wall of the bracket 2. When the adjustment seat 3 slides to the appropriate position, the spring 4 drives the work frame 5 to slide through its own elastic force. The work frame 5 slides through the guide groove 7 and drives the telescopic column 9 at one end of the guide column 8 to slide horizontally along the inner wall of the adjustment seat 3, so that the telescopic column 9 slides to fit into the adjustment hole 10, thereby realizing the adjustment operation of the interval between the adjustment seats 3, which is convenient for placing dumbbells of different sizes.

[0027] In one embodiment, the guide groove 7 is inclined.

[0028] In this embodiment, the work frame 5 slides through the guide groove 7 to drive the telescopic column 9 at one end of the guide column 8 to slide horizontally along the inner wall of the adjustment seat 3, so that the telescopic column 9 slides to engage with the adjustment hole 10, thereby realizing the adjustment operation of the interval between the adjustment seats 3 and the sliding operation of the telescopic column 9.

[0029] In one embodiment, the adjustment holes 10 are equidistantly distributed along the outer wall of the bracket 2.

[0030] In this embodiment, the equidistantly distributed adjustment holes 10 facilitate the adjustment of the interval between the adjustment seats 3.

[0031] In one embodiment, the top of the placement plate 12 is provided with an arc-shaped groove.

[0032] In this embodiment, the groove provided at the top of the placement plate 12 helps to improve the stability of the dumbbell placement and prevent the dumbbell from falling off.

[0033] In one embodiment, a screw 13 is provided at the top of the stabilizing frame 11, and a lifting block 14 is threadedly connected to the outer wall of the screw 13. A connecting rod 15 is screwed to both ends of the lifting block 14. A stabilizing seat 16 that is fixedly connected to the side wall of the placement plate 12 is screwed to one end of the connecting rod 15. A limiting plate 17 that is slidably connected to the side wall of the placement plate 12 is fixedly connected to the outer wall of the stabilizing frame 11.

[0034] In this embodiment, the lifting block 14 drives the placement plate 12 on the outer wall of the stabilizing seat 16 to slide along the outer wall of the limiting plate 17 via the connecting rod 15, thereby realizing the adjustment of the distance between the placement plates 12, which is beneficial to improving the stability of placing dumbbells.

[0035] In one embodiment, the placement plate 12 forms a sliding structure with the limiting plate 17 via the lifting block 14 and the connecting rod 15.

[0036] In this embodiment, the lifting block 14 drives the placement plate 12 on the outer wall of the stabilizing seat 16 to slide along the outer wall of the limiting plate 17 via the connecting rod 15, thereby realizing the sliding operation of the placement plate 12.

[0037] In one embodiment, the cross-section of the limiting plate 17 is "T" shaped.

[0038] In this embodiment, a limiting plate 17 with a "T"-shaped cross-section is provided to prevent the placement plate 12 from falling off after long-term use.

[0039] In this embodiment, the adjustable dumbbell rack is used by first adjusting the spacing between the adjustment seats 3. The user slides the adjustment seat 3 along the outer wall of the support 2. When the adjustment seat 3 slides to the appropriate position, the spring 4 drives the working frame 5 to slide through its own elasticity. The working frame 5 slides through the guide groove 7, which drives the telescopic column 9 at one end of the guide column 8 to slide horizontally along the inner wall of the adjustment seat 3, so that the telescopic column 9 slides to fit into the adjustment hole 10, thereby realizing the adjustment operation of the spacing between the adjustment seats 3, which is convenient for placing dumbbells of different sizes.

[0040] Next, the spacing between the placement plates 12 is adjusted. The user rotates the screw 13, which causes the lifting block 14 to slide vertically. The lifting block 14, through the connecting rod 15, causes the placement plates 12 on the outer wall of the stabilizing seat 16 to slide along the outer wall of the limiting plate 17, thereby realizing the adjustment of the spacing between the placement plates 12, which helps to improve the stability of placing dumbbells.

[0041] Finally, the staff placed the dumbbells into the grooves on the placement plate 12 to achieve stable storage of the dumbbells.
