The scale disk is arranged at the middle position of the base and is rotationally connected to the base. A scale structure is arranged on the inner side surface of the scale disk. A through hole axially penetrating is arranged at the central position of the scale disk. A connecting seat is arranged at the top of the base. A surrounding wall is arranged inside the connecting seat. The surrounding wall and the outer wall of the connecting seat enclose a connecting cavity. Screw hole positions for connection are arranged in the connecting cavity.

[0006] In one or more embodiments, a columnar body is arranged in the connecting cavity, and the screw hole positions are arranged on the central axis of the columnar body.

[0007] In one or more embodiments, a plurality of reinforcing ribs are arranged between the outer side of the connecting seat and the surrounding wall.

[0008] In one or more embodiments, the scale disk includes an inner disk shell and an outer disk shell. A limiting structure is arranged on the inner side wall of the base. The inner disk shell and the outer disk shell are respectively arranged on both sides of the limiting structure and are in contact with the limiting structure. The inner disk shell and the outer disk shell are fixedly connected by screws. The scale structure is arranged on the outer surface of the inner disk shell.

[0009] In one or more embodiments, the limiting structure is composed of a plurality of limiting steps distributed at intervals in a ring shape.

[0010] In one or more embodiments, an annular connecting wall extending towards the inner disk shell is arranged on the inner side of the outer disk shell, and an annular concave position connected to the annular connecting wall is arranged on the inner side of the inner disk shell.

[0011] The effects of the present utility model compared with the background technology are as follows: The overall structure of the dial is compact and reasonably designed, with excellent anti-collision ability. And it is equipped with a dial structure that can rotate with the grip, so that when the user rotates the grip to adjust the weight of the dumbbell plate, the user can intuitively view the selected dumbbell weight.

Detailed Embodiment

[0015] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in combination with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0016] Please refer to Figures 1-3 , the present application provides a dial structure of a dumbbell, which includes an annular base 1 and a dial. The dial is arranged in the middle of the base and is rotatably connected to the base. A scale structure is arranged on the inner side surface of the dial. A through hole 2 is axially penetrated through the center position of the dial. The through hole of the dial is used for connecting the grip, so that the dial can rotate with the rotation of the grip. Thus, when the user rotates the grip to select the dumbbell weight, the dial also rotates accordingly to reflect the corresponding weight. A connecting seat 3 is arranged on the top of the base. A surrounding wall 4 is arranged in the connecting seat. The surrounding wall and the outer wall of the connecting seat enclose a connecting cavity. A screw hole position 5 for connection is arranged in the connecting cavity. The connecting cavity is used for connecting with the shell, and is specifically connected and fixed by screws.

[0017] A columnar body 6 is arranged in the connecting cavity. The screw hole position 5 is opened on the central axis of the columnar body. Arranging the columnar body can increase the depth of the screw hole position, make its tightness and connectivity better after being connected with the screw, and reduce the possibility of slipping of the thread. In order to ensure the structural strength of the surrounding wall, a plurality of reinforcing ribs 7 are arranged between the outer sides of the connecting seat 3 and the surrounding wall 4.

[0018] The dial includes an inner disc housing 8 and an outer disc housing 9. A limiting structure is provided on the inner side wall of the base 1. The inner disc housing 8 and the outer disc housing 9 are respectively arranged on both sides of the limiting structure and are in contact with the limiting structure. The inner disc housing and the outer disc housing are fixedly connected by screws 10. The scale structure is arranged on the outer surface of the inner disc housing. After connecting the inner disc housing and the outer disc housing by screws, it can only rotate relative to the base. Since the scale structure is arranged on the inner disc housing, when producing dumbbells, various designs can be made for the color of the inner disc housing and the design of the scale structure according to needs, providing more choices for users.

[0019] The limiting structure is composed of a plurality of limiting steps 11 distributed at intervals in a ring shape to reduce the contact area and the friction force, making the dial rotate more smoothly.

[0020] The inner side of the outer disc housing 9 has an annular connecting wall 12 extending towards the inner disc housing. An annular concave position 13 connected to the annular connecting wall is provided on the inner side of the inner disc housing 8. The concave position and the annular connecting wall are cooperatively connected, which can improve the structural connection tightness after the inner disc housing and the outer disc housing are assembled.

[0021] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention should be included in the protection scope recorded in the claims.
