Description

Technical Field

[0001] The utility model belongs to the field of fitness equipment, and in particular relates to a dumbbell plate. Background Art

[0002] Dumbbells and barbells are auxiliary equipment for weightlifting and fitness exercises. They are used in combination with dumbbell plates and barbell plates through grips and are one of the most common fitness equipment.

[0003] However, existing dumbbell plates usually adopt a design with hole-shaped reinforcement ribs and external plugging covers on the outer circle, and the reinforcement ribs are directly set on the dumbbell plates, which not only has a high manufacturing cost, but also is prone to surface defects, affecting normal use; and traditional dumbbell plates are generally round, and improper operation can easily cause the dumbbell plates to fall and roll and injure pedestrians, which lacks safety. Summary of the Invention

[0004] The purpose of the utility model is to provide a dumbbell piece which can reduce manufacturing cost, improve safety, and has a reasonable blow molding port arrangement without affecting use.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] A dumbbell plate, characterized in that it includes a plate body and a cover plate, wherein a through hole is opened in the center of the plate body, and recessed planes are provided on the front and rear surfaces of the plate body, and a plurality of hole-shaped reinforcement ribs and a plurality of blow molding process holes are provided on the recessed planes, and the cover plate covers the recessed planes and covers and hides the hole-shaped reinforcement ribs and the blow molding process holes.

[0007] Furthermore, the sheet is 12-sided.

[0008] Furthermore, the sheet body is provided with a plurality of hand-gripping holes.

[0009] The beneficial effects of the present invention are:

[0010] By changing the position of the hole-shaped reinforcement ribs and adopting a cover-free design, the manufacturing process is optimized, the manufacturing cost is greatly reduced, and the surface defects of the dumbbell plates are eliminated, making them more comfortable and durable to use. At the same time, the overall polygonal design makes the dumbbell plates less likely to roll, thereby improving safety in use.

[0011] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the exploded structure of the front side of a dumbbell plate shown in one embodiment of the present invention;

[0014] Figure 3 This is a structural schematic diagram of the back side of a dumbbell plate shown in one embodiment of the present invention.

[0015] Description of the accompanying symbols: 1. Sheet; 2. Hand grip hole; 3. Perforation; 4. Cover plate; 5. Hole-shaped reinforcement rib; 6. Blow molding process hole. DETAILED DESCRIPTION

[0016] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] See Figure 1-2 The dumbbell plate shown in a preferred embodiment of the present application includes a plate body 1 and a cover plate 4. The plate body 1 is 12-sided, and a through hole 3 for connecting the handle is opened in the center of the plate body 1. Two hand-gripping holes 2 are also provided on the plate body 1.

[0021] A recessed plane is provided on the front and rear surfaces of the sheet body 1. The shape of the recessed plane is the same as that of the cover plate 4. One of the recessed planes is provided with a blow molding process hole 6 and three hole-shaped reinforcing ribs 5 for increasing the structural strength. The other recessed plane is also provided with three hole-shaped reinforcing ribs 5. The two cover plates 4 respectively cover the recessed planes on both sides to cover and hide the hole-shaped reinforcing ribs 5 and the blow molding process hole 6.

[0022] In other embodiments, the number of the blow molding process holes 6 and the hole-shaped reinforcement ribs 5 can be any number and can be arbitrarily distributed on the concave planes on both sides.

[0023] Working principle:

[0024] The utility model is formed by blow molding the holes 6 in one piece. After forming, cement is poured into the holes 6. After the cement is set, the cover plate 4 is directly used to block and conceal the hole-shaped reinforcement ribs 5 and the blow molding holes 6 with adhesive or other means. This manufacturing process is more cost-effective than existing technologies, does not have uneven surface defects, is more comfortable to use, and the polygonal structure is less likely to roll and is safer.

[0025] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
