[0022] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model is further described in detail below with reference to the accompanying drawings.

[0024] Combined with Figure 1-8 The specific implementation process of the utility model of a novel adjustable dumbbell is as follows:

[0025] A novel adjustable dumbbell comprises a handle 1, inner end plates 2 are fixed on both sides of the handle 1, the inner end plates 2 serve as a connecting bridge between dumbbell plates 3 and the handle 1, and a plurality of dumbbell plates 3 are arranged outside the inner end plates 2;

[0026] A limiting piece 4 is provided on the edge of the dumbbell piece 3, and slots 5 are provided on both sides of the limiting piece 4 and are offset therefrom. An inserting piece 6 is provided in the slot 5 and is inserted thereinto and connected to the next dumbbell piece 3. A threaded hole 7 penetrating the dumbbell piece 3 and the inserting piece 6 is provided. A plurality of dumbbell pieces 3 and the inserting piece 6 are connected and fixed in sequence by cooperating with the screw rod and the threaded hole 7. The weight of the entire dumbbell can be adjusted by increasing or decreasing the number of dumbbell pieces 3. Two adjacent dumbbell pieces 3 are clamped by the inserting piece 6, and the connection is strengthened by a threaded rod.

[0027] In one embodiment of the present application, in order to make the connection between the dumbbell pieces 3 more stable, the limiting pieces 4 are symmetrically arranged on the upper and lower sides of the dumbbell pieces 3, and the two sides of the limiting pieces 4 are insert piece cavities 8. The insert piece cavities 8 allow the bent part of the insert piece 6 to have sufficient placement space, and the card slot 5 is arranged on the dumbbell piece 3 at the edge of the insert piece cavity 8.

[0028] Preferably, the limiting plate 4 and the slot 5 are staggered and the sum of their thicknesses is the thickness of the dumbbell plate 3. The limiting plate 4 is a thin plate at the end of the dumbbell plate 3, which is equivalent to the thin plate left after part of the thickness of the dumbbell plate 3 is cut off, and the cut thickness is the thickness of the slot 5. The slot 5 is located on both sides of the limiting plate 4, and cooperates with the end face of the next dumbbell plate 3 to form a cavity, which is convenient for the two ends of the plug to be inserted into it.

[0029] In one embodiment of the present application, at least two guide cylinders 9 are provided between the two inner end plates 2, and the guide cylinder 9 is provided with an adjustment groove 10 and a positioning hole 11, an axial adjustment rod 12 is provided in the guide cylinder 9, and a positioning pin 13 is provided on the axial adjustment rod 12 to cooperate with the positioning hole 11, and a plug-in hole 14 is provided on the dumbbell plate 3 to plug and cooperate with the axial adjustment rod 12; the axial adjustment rod 12 is provided with a radial hole 15, and a threaded section 16 is provided in the radial hole 15, and a positioning pin 13 is inserted into the radial hole 15 and can be spirally adjusted therein. Through this structural setting, after the axial adjustment rod 12 is placed in the guide cylinder 9, the positioning pin 13 is moved axially in the adjustment groove 10, driving the entire axial adjustment rod 12 to be inserted into the dumbbell plate 3 to fix the dumbbell plate 3, and when plugged into the predetermined position, the positioning pin 13 can be inserted into the positioning hole 11 by screwing to achieve positioning.

[0030] Preferably, in order to make the plug-in more secure, the cross-section of the axial adjustment rod 12 can be designed to be a polygonal structure, such as a rectangular or trapezoidal structure, and the plug-in hole 14 is clearance-matched therewith.

[0031] Preferably, a spring 17 is provided on the periphery of the positioning pin 13, and a gasket 18 is provided under the spring 17. When the axial adjustment rod 12 moves laterally in the guide cylinder 9, the spring 17 constrains the entire positioning pin 13 from shaking after being plugged into the positioning hole 11.

[0032] Preferably, the handle 1 is provided with anti-skid patterns 19, which make it easier to hold the dumbbell and prevent it from getting loose easily.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
