Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fitness equipment, in particular to a novel dumbbell plate. Background Art
[0002] Dumbbells and barbells are commonly used fitness equipment. Existing barbells and dumbbells have dumbbell barbell plates fixed at both ends of the rod body. Traditional dumbbell barbell plates are generally divided into cast iron plates or pure iron plates. The cast iron plates or pure iron plates are prepared by casting, stamping, cutting and other methods. Special stamping equipment is required for stamping during the production process, and the stamping cost is high. Since the plate body is made of metal, it is difficult to process its surface, especially for appearance modeling. After the plate body is formed, subsequent treatments such as polishing and electroplating are required, and the production and processing efficiency is low. Utility Model Content
[0003] The utility model aims to provide a novel dumbbell plate, which can improve its functionality and adjust the weight in real time.
[0004] According to the utility model, a new dumbbell plate is provided, including a dumbbell plate shell, a cavity is provided in the dumbbell plate shell, a filling port is provided on the side wall of the dumbbell plate shell, a filler is poured into the cavity through the filling port, two grasping spaces are provided on the dumbbell plate shell, handles are formed on the sides of the two grasping spaces, and a sealing portion is detachably connected to the filling port.
[0005] Furthermore, a slide groove is provided along the length direction of the inner wall of the dumbbell plate shell, and the blocking portion is a sliding piece slidably connected to the slide groove, and the sliding piece blocks or opens the filling port after sliding into place.
[0006] Furthermore, a limiting portion for limiting the position of the sliding sheet is fixed on the side wall of the sliding groove.
[0007] Furthermore, a toggle plate is arranged on the outer side of the sliding plate.
[0008] Furthermore, the dumbbell plate shell is covered with a rubber layer.
[0009] Furthermore, the rubber layer material is thermoplastic elastomer TPE / TPR.
[0010] Furthermore, a pair of reinforcement holes are opened radially along the dumbbell plate shell, and the reinforcement holes are symmetrical with respect to the axis of the dumbbell plate shell. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 This is a schematic structural diagram of a novel dumbbell plate according to an embodiment of the utility model;

[0014] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0015] Combination Figure 1 , shows a new dumbbell piece of the utility model, including a dumbbell piece shell 1, a cavity is provided in the dumbbell piece shell 1, a filling port is opened on the side wall of the dumbbell piece shell 1, a filler is poured into the cavity through the filling port, two grasping spaces 2 are opened on the dumbbell piece shell 1, handles 6 are formed on the sides of the two grasping spaces 2, and a sealing part is detachably connected to the filling port.
[0016] Before use, a filler of required weight can be poured through the filling port, and then sealed through the sealing portion. During actual use, the user can reach into the grasping space 2, hold the handle 6, and pick up the dumbbell.
[0017] A slide groove is arranged along the length direction of the inner wall of the dumbbell plate housing 1, and the blocking part is a sliding piece 3 slidably connected to the slide groove. After the sliding piece 3 slides into place, the filling port is blocked or opened.
[0018] The filling port can be blocked or opened by sliding the sliding sheet 3 , and the filling port is not only a channel for pouring the filling material but also a channel for discharging the filling material.
[0019] A limiting portion 7 for limiting the position of the sliding sheet 3 is fixed on the side wall of the sliding groove.
[0020] A shifting piece 4 is arranged outside the sliding piece 3 .
[0021] The dumbbell plate housing 1 is covered with a rubber layer.
[0022] The rubber layer material is thermoplastic elastomer TPE / TPR.
[0023] Thermoplastic elastomers TPE / TPR have many advantages, including good impact and fatigue resistance, high impact strength, good low-temperature flexibility, maintaining good performance when the temperature rises, resistance to chemicals, oils, solvents and weather, high tear resistance and high friction resistance, good recyclability, soft touch and excellent surface quality. In addition, its hardness range is wide, ranging from OA - 100A. Generally speaking, thermoplastic elastomers TPE / TPR are a kind of high-performance and environmentally friendly materials with wide uses, excellent performance, broad market prospects and development potential.
[0024] A pair of reinforcing holes 5 are radially formed in the dumbbell piece housing 1, and the reinforcing holes 5 are symmetric about the axis of the dumbbell piece housing 1.
[0025] The principle of the present utility model is as follows:
[0026] Before use, the required weight of the filler can be poured through the filling port, and then it is sealed by the sealing part. During actual use, the user can put his hand into the grasping space 2 and hold the handle 6 to lift the dumbbell piece.
[0027] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
