Description

Technical Field

[0001] The utility model relates to the field of dumbbells, in particular to a dumbbell positioning structure. Background Art

[0002] Dumbbells are common fitness equipment. Currently, some models on the market allow users to adjust the number of dumbbell plates, or in other words, the overall weight, by rotating the dumbbell grip. This allows users to adjust the weight at any time based on training needs, making them popular due to their ease of use. However, these adjustable dumbbells have a certain amount of play between the plates and the plate holder. This can cause localized pressure on the plates during use, leading to damage to the plate surface.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a dumbbell positioning structure, which solves the problem of partial compression and damage of dumbbell plates.

[0005] The utility model proposes a dumbbell positioning structure, which includes a plurality of dumbbell plate seats connected and linked, an axial hole is opened in the middle position of the dumbbell plate seat, the dumbbell plate seat is located on the dumbbell plate placement surface and is provided with a plurality of arc-shaped supporting parts and a plurality of positioning parts, the plurality of arc-shaped supporting parts and the plurality of positioning parts are axially spaced apart, and release openings are formed between the arc-shaped supporting parts, between the arc-shaped supporting parts and the positioning parts, and between the positioning parts.

[0006] In one or more embodiments, the plurality of arc-shaped supporting portions and the plurality of positioning portions are disposed near an outer edge of the dumbbell plate holder.

[0007] In one or more embodiments, an annular connecting platform is provided on the edge of the hole surrounding the axis hole on the dumbbell plate placement surface, and a plurality of protruding connecting parts are provided on the end surface of the annular connecting platform. The dumbbell plate seat is located on the other side of the dumbbell plate placement surface and is provided with a connecting hole that cooperates with the connecting part.

[0008] In one or more embodiments, a plurality of reinforcing ribs are provided between the outer side surface of the annular connecting platform and the dumbbell plate placement surface.

[0009] In one or more embodiments, the dumbbell plate holder is provided with a recess on the other side of the dumbbell plate placement surface, the connecting hole is opened in the recess, and the end of the annular connecting platform can be inserted into the recess.

[0010] Compared with the prior art, this solution has the following beneficial effects: by providing a positioning portion on the dumbbell plate seat to form contact with the dumbbell plate, the dumbbell plate cannot shake on the dumbbell plate seat, thereby solving the problem of local pressure and skin breakage of the dumbbell plate.

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0015] Please see attached Figure 1-3 The utility model provides a dumbbell positioning structure, which includes a plurality of connected and linked dumbbell plate seats 1, an axial hole 2 is opened in the middle position of the dumbbell plate seat, and the axial hole is used for the dumbbell shaft rod to pass through. The dumbbell plate seat is located on the dumbbell plate placement surface 3 and is provided with a plurality of arc-shaped supporting parts 4 and a plurality of positioning parts 5. The function of the arc-shaped supporting parts 4 is to support the dumbbell plates 13. The plurality of arc-shaped supporting parts and the plurality of positioning parts are axially spaced apart. A release opening 6 is formed between the arc-shaped supporting parts 4 and the arc-shaped supporting parts, between the arc-shaped supporting parts and the positioning parts 5, and between the positioning parts 5 and the positioning parts. The release opening is used for the supporting parts 131 on the dumbbell plates to pass through. After the supporting parts pass through, the dumbbell plates are separated from the dumbbell plate seat.

[0016] The multiple arc-shaped supporting parts 4 and the multiple positioning parts 5 are arranged near the outer edge of the dumbbell plate holder 1. The end of the positioning part facing the axial direction is in the shape of a spire, and has arc-shaped transition structures on both sides to play a guiding role.

[0017] An annular connecting platform 7 is provided along the edge of the hole surrounding the axis hole on the dumbbell plate placement surface 3, and a plurality of protruding connecting parts 8 are provided on the end surface of the annular connecting platform. The dumbbell plate seat is located on the other side of the dumbbell plate placement surface and is provided with a connecting hole 9 that cooperates with the connecting part. Multiple dumbbell plate seats are spliced front and back, and the connecting part is connected and cooperated with the connecting hole to realize the linkage of multiple dumbbell plate seats.

[0018] A plurality of reinforcing ribs 10 are provided between the outer side surface of the annular connecting platform 7 and the dumbbell plate placement surface 3 , and the reinforcing ribs can strengthen the structural strength of the annular connecting platform and improve its force-bearing capacity.
