[0021] The present utility model provides the following description with reference to the drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0022] In the description of the present utility model, the orientation description is involved. For example, the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0023] It should be understood that when an element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there may be an intermediate element (e.g., a third element) between the element and the other element.

[0024] An embodiment of the present utility model provides an integrated dumbbell with an internal support, as Figure 1 and Figure 2 shown, including a housing 100 and a support member 200. The housing 100 has a receiving cavity for loading weights to increase the weight of the entire dumbbell. The housing 100 includes a gripping portion 110 and two weight-increasing portions 120. The two weight-increasing portions 120 are respectively located at both ends of the gripping portion 110 and are integrally connected to the gripping portion 110. Therefore, the entire housing 100 is integrally formed. The gripping portion 110 is for a user to hold with their hand, and the weight-increasing portion 120 is the heavier part of the entire dumbbell. The support member 200 is fixed inside the housing 100 and is located at the gripping portion 110, and the gripping portion 110 covers the circumferential surface of the support member 200. The support member 200 can be made of hard plastic, metal, or other hard materials. The support member 200 provides support to the gripping portion 110 from the inside, which is equivalent to increasing the hardness of the gripping portion 110, making the gripping portion 110 not easily bend, thereby improving the user experience.

[0025] In some embodiments, the weight-increasing portion 120 includes a connecting portion 130 connected to the gripping portion 110. The connecting portion 130 is part of the weight-increasing portion 120 and is directly connected to the gripping portion 110. In the direction away from the gripping portion 110, the cross-sectional area of the connecting portion 130 gradually increases, which is equivalent to the connecting portion 130 gradually getting thicker. Since the weight-increasing portion 120 is the main weight-increasing part of the entire dumbbell and its size is usually larger than that of the gripping portion 110, in this embodiment, the connecting portion 130 is set to a gradually thickening structure. Through the transition of the connecting portion 130, the size of the gripping portion 110 gradually changes to the size of the weight-increasing portion 120, making it more comfortable for the user to hold. And because it is a gradient structure without large corners, the housing 100 is easier to demold after molding.

[0026] In this embodiment, the gripping portion 110 can be similar to a cylindrical shape, and the connecting portion 130 can be similar to a frustum shape, so that the user can grip the gripping portion 110 from any angle, which is convenient for use.

[0027] Furthermore, engaging portions 210 are provided at both ends of the support member 200. In the direction from the holding portion 110 to the weight increasing portion 120, the cross-sectional area of the engaging portion 210 gradually increases, which is equivalent to the engaging portion 210 gradually becoming thicker. The two engaging portions 210 respectively extend into the two connecting portions 130, and the two connecting portions 130 respectively cover the peripheral surfaces of the two engaging portions 210. The two engaging portions 210 respectively provide support to the two connecting portions 130 from the inside, making it not easy for the connecting portions 130 to bend and deform, thereby further enhancing the user experience. At the same time, the cross-sectional area of the engaging portion 210 is larger than the cross-sectional area of the middle portion of the support member 200. The engaging portion 210 cannot pass through the holding portion 110. The two engaging portions 210 limit the relative movement of the support member 200 with respect to the holding portion 110 from both ends of the support member 200, thereby clamping the support member 200 at the holding portion 110. This does not require the use of connecting members such as screws, effectively utilizing the inherent structural characteristics of the product and not causing damage to the product.

[0028] In some embodiments, a through hole 201 penetrating the support member 200 is provided on the end face of the support member 200. The weight increasing object can move between the two weight increasing portions 120 through the through hole 201, which increases the fluidity of the weight increasing object within the housing 100, making it easier for the weight increasing object to fill the entire housing 100.

[0029] Furthermore, an opening 101 for filling the weight increasing object is provided on the surface of at least one weight increasing portion 120. The user can insert the weight increasing object into the housing 100 through the opening 101, or take out the weight increasing object within the housing 100 through the opening 101. A plug body is provided at the opening 101. The plug body can open or cover the opening 101. When the plug body is opened, the user can insert the weight increasing object into the housing 100 or take out the weight increasing object within the housing 100; after the plug body covers the opening 101, it can prevent the weight increasing object in the housing 100 from falling out.

[0030] Even further, the weight increasing object is a granular weight increasing object, such as sand, metal balls, etc. The granular weight increasing object has better fluidity and is easy to flow within the housing 100 to facilitate filling the entire housing 100. At the same time, the size of the granular weight increasing object is small, so the opening 101 can be made small, making it easy to put the granular weight increasing object into the housing 100 or take it out of the housing 100.

[0031] In some embodiments, a plurality of anti-slip lines 102 are provided on the surface of the holding portion 110 to increase the friction force, so that the user is not easy to slip when grasping the holding portion 110. Among them, the extending direction of the anti-slip lines 102 can be parallel to the extending direction of the holding portion 110, and such a setting has a better anti-slip effect.

[0032] Furthermore, the anti-slip pattern 102 extends to the surface of the weight-increasing portion 120, which is equivalent to increasing the length of the anti-slip pattern 102 and can further enhance the anti-slip effect.

[0033] In some embodiments, an installation groove 103 is provided on the surface of the holding portion 110, and a nameplate 300 is fixed in the installation groove 103. The nameplate 300 can record trademarks, logos, slogans, enterprise information or other information. Since the nameplate 300 is fixed in the installation groove 103, the surface of the holding portion 110 is relatively flat, ensuring the comfort of the user when grasping.

[0034] In some embodiments, the housing 100 of this embodiment can be made of silicone, which is softer. When it falls to the ground, it has an elastic buffering effect, will not damage the ground, nor will it hurt the user's feet.

[0035] The terms and words used in the above description and claims are not limited to the literal meanings, but are used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present invention is only for illustration, rather than to limit the present invention as defined by the appended claims and their equivalents.
