Technical Field
[0001] This utility model relates to the field of dumbbell technology, and in particular to a dumbbell that can reduce the impact force when landing. Background Technology
[0002] Dumbbells are simple pieces of equipment used to enhance muscle strength. They are an auxiliary tool in weightlifting and fitness exercises and are smaller than barbells.
[0003] Most dumbbells are made of metal, and given their weight, they are prone to falling, especially when placed on the ground. This can lead to damage to the ground or breakage of the dumbbell due to the impact. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a dumbbell that can reduce the impact force upon landing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dumbbell that can reduce the impact force of landing is designed, including a handle, with connecting shafts installed at both ends of the handle, and a dumbbell plate at the end of the handle, with a fixing hole coaxially opened on the dumbbell plate, the fixing hole corresponding to the connecting shaft.
[0006] A first locking nut is threaded to the end of the connecting shaft away from the handle, and an annular sheath is provided along the outer wall of the dumbbell plate. The sheath is fixed to the dumbbell plate by a connector.
[0007] The sheath consists of an outer layer and an inner layer. The outer layer is a ring-shaped silicone plate, and the inner layer is a sponge pad fixed inside the silicone plate.
[0008] Preferably, the handle is fitted with a non-slip rubber sleeve.
[0009] Preferably, at least one limiting block is installed on the outer wall of the connecting shaft, the limiting block is arranged along the axial direction of the connecting shaft, and a limiting groove corresponding to the limiting block is opened on the inner wall of the fixing hole, the limiting groove is arranged through the dumbbell plate.
[0010] Preferably, a limiting plate is coaxially installed at one end of the connecting shaft near the handle, and several strip plates are installed at intervals along the edge of the limiting plate.
[0011] Preferably, a reinforcing plate is installed on the side of the strip plate away from the dumbbell plates, the reinforcing plate is vertically fixed to the strip plate, and one side of the reinforcing plate is fixed to the connecting shaft.
[0012] Preferably, a first through hole is provided along the edge of the dumbbell plate, and the connector includes a connecting plate. The connecting plate is annular and installed on both sides of the sheath. A second through hole corresponding to the first through hole is provided on the connecting plate, and a screw is installed in the first through hole. The end of the screw passes through the second through hole and is threadedly connected to a second locking nut.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-5 A dumbbell designed to reduce the impact of a fall includes a handle 1 with a non-slip rubber sleeve, which improves the anti-slip effect when the user holds the handle 1, thereby reducing the possibility of the dumbbell falling during use.
[0025] A connecting shaft 2 is installed at both ends of the handle 1, and a dumbbell plate 4 is also provided at the end of the handle 1. A fixing hole 5 is coaxially opened on the dumbbell plate 4, and the fixing hole 5 corresponds to the connecting shaft 2, so that the dumbbell plate 4 can be sleeved on the connecting shaft 2 for installation. A first locking nut 12 is threadedly connected to the end of the connecting shaft 2 away from the handle 1, which is used to fix the dumbbell plate 4 on the connecting shaft 2.
[0026] In order to improve the stability of the dumbbell plate 4 on the connecting shaft 2, therefore, Figure 1 and Figure 3 As shown, a limiting plate 13 is coaxially installed at one end of the connecting shaft 2 near the handle 1, and several strip plates 14 are installed along the edge of the limiting plate 13 at intervals to increase the contact area of the dumbbell plate 4 on the connecting shaft 2, thereby improving the fixing effect of the dumbbell plate 4 on the connecting shaft 2.
[0027] Furthermore, a reinforcing plate 15 is installed on the side of the strip plate 14 away from the dumbbell plate 4. The reinforcing plate 15 is vertically fixed to the strip plate 14, and one side of the reinforcing plate 15 is fixed to the connecting shaft 2, which improves the support strength of the strip plate 14, thereby allowing the strip plate 14 to provide better support for the dumbbell plate 4.
[0028] Specifically, such as Figure 2 and Figure 3 As shown, at least one limiting block 3 is installed on the outer wall of the connecting shaft 2. The limiting block 3 is set along the axial direction of the connecting shaft 2, and a limiting groove 6 corresponding to the limiting block 3 is opened on the inner wall of the fixing hole 5. The limiting groove 6 passes through the dumbbell plate 4. When the dumbbell plate 4 is placed on the connecting shaft 2, the limiting block 3 can be placed in the limiting groove 6 to limit the dumbbell plate 4 on the connecting shaft 2, so as to prevent the dumbbell plate 4 from shaking or rotating on the connecting shaft 2 unnecessarily during use, thereby affecting the normal use of the dumbbell.
[0029] like Figure 1 and Figure 4As shown, an annular sheath 8 is provided along the outer wall of the dumbbell plate 4. The sheath 8 is fixed to the dumbbell plate 4 by a connector. A first through hole 7 is provided along the edge of the dumbbell plate 4. The connector includes a connecting plate 9, which is annular and installed on both sides of the sheath 8. A second through hole 16 corresponding to the first through hole 7 is provided on the connecting plate 9. A screw 10 is installed in the first through hole 7. The end of the screw 10 passes through the second through hole 16 and is threadedly connected to a second locking nut 11. After the sheath 8 is put on the outer wall of the dumbbell plate 4, the screw 10 can be removed and passed through the through hole until the end of the screw 10 protrudes from the second through holes 16 on both sides. Then the second locking nut 11 can be removed and screwed onto the screw 10 to fix the sheath 8. In this way, the sheath 8 can be detachably installed on the dumbbell plate 4, which facilitates the removal and replacement of the sheath 8.
[0030] Furthermore, a washer is provided on the side of the first locking nut 12 near the dumbbell plate 4. The washer is sleeved on the connecting shaft 2, which can improve the fastening effect of the first locking nut 12 threadedly connected to the connecting shaft 2.
[0031] It should be noted that, as Figure 5 As shown, the sheath 8 includes an outer layer 17 and an inner layer 18. The outer layer 17 is a ring-shaped silicone plate, and the inner layer 18 is a sponge pad fixed inside the silicone plate. When the dumbbell falls to the ground, the silicone of the outer layer 17 will come into contact with the ground. In this way, the elasticity of the silicone and the deformation of the sponge can buffer the dumbbell's landing process, thereby reducing the impact force of the dumbbell on the ground and preventing the dumbbell from causing damage to the ground or the dumbbell when it falls to the ground.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
