Technical Field
[0001] This utility model relates to the field of dumbbell technology, and in particular to an embedded shock-absorbing dumbbell. Background Technology
[0002] Dumbbells are a common piece of fitness equipment, typically used for strength training and muscle building. They generally consist of a long bar and weights at both ends, which can be adjusted to suit individual needs.
[0003] In the existing technology, dumbbells are relatively heavy. If the user becomes exhausted or drops the dumbbell during use, the dumbbell itself lacks shock absorption and protection. If it falls directly to the ground, it may not only injure the user and pose a certain safety hazard, but it will also damage the dumbbell and affect its service life. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing technology, when dumbbells are heavy, if the user becomes exhausted or drops them, the dumbbell body lacks shock absorption protection and may fall directly to the ground, which may not only injure the user and pose a certain safety hazard, but also damage the dumbbell and affect its service life. Therefore, an embedded shock-absorbing dumbbell is proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] An embedded shock-absorbing dumbbell includes a handle and two nested cylinders. The two nested cylinders are respectively fixedly connected to both ends of the handle. Threaded mounting rods are fixedly connected to the inner walls of the two nested cylinders. Multiple dumbbell plates are movably sleeved on the wall of each threaded mounting rod. Mounting rings are threadedly connected to the wall of each threaded mounting rod. Multiple grooves are formed around the wall of each nested cylinder. Two sliding rods are slidably mounted on the inner wall of each nested cylinder within the grooves. Elastic shock-absorbing plates are fixedly connected to the corresponding sides of the two sliding rods. Multiple strip-shaped openings are formed around the wall of each nested cylinder at the gap between the grooves.
[0007] Preferably, a plurality of levers are fixedly connected around the side wall of the mounting ring, and the side wall of the mounting ring is pressed against the side wall of the dumbbell plate.
[0008] Preferably, the elastic damping plate is configured as an arc-shaped plate and extends to the outside of the nested cylinder located in the groove.
[0009] Preferably, a connecting plate is fixedly connected to the side wall of the slide rod, a fixing rod is fixedly connected to the side wall of the connecting plate, a top plate is movably sleeved on the rod wall of the fixing rod, an opening is opened on the inner wall of the nesting cylinder located in the groove, and the end of the top plate opposite to the fixing rod passes through the opening and extends to the inner wall of the nesting cylinder located in the strip-shaped opening.
[0010] Preferably, a rubber buffer pad is fixedly connected to one end of the top plate located inside the strip opening, and the rubber buffer pad is pressed against the inner wall of the nesting cylinder located in the strip opening.
[0011] Preferably, a guide block is fixedly connected to one side of the sliding rod relative to the nesting cylinder, and a guide groove is provided on the inner wall of the nesting cylinder located in the groove, and the guide block is slidably disposed on the inner wall of the guide groove.
[0012] Compared with the prior art, this utility model provides an embedded shock-absorbing dumbbell, which has the following beneficial effects:
[0013] 1. This embedded shock-absorbing dumbbell can protect the edge of the nested cylinder through the sliding rod and elastic shock-absorbing plate. If the nested cylinder expands, the elastic shock-absorbing plate will be squeezed and bent to buffer and absorb shock, reducing damage when impacted and reducing safety hazards.
[0014] 2. This embedded shock-absorbing dumbbell has dumbbell plates fitted onto the wall of a threaded mounting rod. It can be nested inside a nesting cylinder to facilitate adding weight to the dumbbell. Rotating the lever can drive the mounting ring to rotate and move along the wall of the threaded mounting rod until the side wall of the mounting ring is pressed against the side wall of the dumbbell plate, which can improve the stability of the dumbbell plate inside the nesting cylinder.
[0015] 3. This embedded shock-absorbing dumbbell, by sliding the guide block along the inner wall of the guide groove, can improve the stability of the sliding rod movement and prevent the slide plate from deviating and affecting the use of the elastic shock-absorbing plate.

[0022] 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.
[0023] Reference Figure 1-5 An embedded shock-absorbing dumbbell includes a handle 1 and two nested cylinders 2. The two nested cylinders 2 are respectively fixedly connected to both ends of the handle 1. Threaded mounting rods 3 are respectively fixedly connected to the inner walls of the two nested cylinders 2. Multiple dumbbell plates 4 are movably sleeved on the rod walls of the threaded mounting rods 3. Mounting rings 5 are threadedly connected to the rod walls of the threaded mounting rods 3. Multiple grooves are circumferentially formed on the cylinder walls of the nested cylinders 2. Two sliding rods 7 are respectively slidably arranged on the inner walls of the nested cylinders 2 in the grooves. Elastic shock-absorbing plates 8 are simultaneously fixedly connected to the corresponding sides of the two sliding rods 7. Multiple strip-shaped openings are circumferentially formed on the cylinder walls of the nested cylinders 2 at the gaps between the grooves.
[0024] Multiple levers 6 are fixedly connected around the side wall of the mounting ring 5. The side wall of the mounting ring 5 is pressed against the side wall of the dumbbell plate 4. The elastic damping plate 8 is set as an arc plate and extends to the outside of the nested cylinder 2.
[0025] A connecting plate 9 is fixedly connected to the side wall of the sliding rod 7, and a fixing rod 10 is fixedly connected to the side wall of the connecting plate 9. A top plate 11 is movably sleeved on the rod wall of the fixing rod 10. An opening is opened in the inner wall of the nested cylinder 2 located in the groove. The end of the top plate 11 away from the fixing rod 10 passes through the opening and extends to the inner wall of the nested cylinder 2 located in the strip-shaped opening. A rubber buffer pad 12 is fixedly connected to the end of the top plate 11 located inside the strip-shaped opening. The rubber buffer pad 12 is pressed tightly onto the inner wall of the nested cylinder 2 located in the strip-shaped opening.
[0026] In use, the dumbbell plate 4 is fitted onto the wall of the threaded mounting rod 3 and can be nested inside the nesting cylinder 2, making it easy to add weight to the dumbbell. Rotating the lever 6 can drive the mounting ring 5 to rotate and move along the wall of the threaded mounting rod 3 until the side wall of the mounting ring 5 is pressed against the side wall of the dumbbell plate 4, which can improve the stability of the dumbbell plate 4 inside the nesting cylinder 2. The sliding rod 7 and the elastic shock-absorbing plate 8 can protect the edge of the nesting cylinder 2. If the nesting cylinder 2 expands, the elastic shock-absorbing plate 8 will be squeezed and bent to buffer and absorb shock, reducing damage when impacted and reducing safety hazards.
[0027] When the elastic damping plate 8 bends, it pushes the slide rod 7 to slide along the inner wall of the groove, which in turn pushes the top plate 11 to slide along the inner wall of the opening. This can improve the stability of the slide rod 7 and the elastic damping plate 8 after deformation. The top plate 11 is hinged to the slide rod 7 through the connection between the fixed rod 10 and the connecting plate 9. This can ensure the stability of the connection between the slide rod 7 and the top plate 11 after the slide rod 7 moves. The rubber buffer pad 12 can improve the protection effect of the top plate 11.
[0028] To improve the stability of the movement of slider 7, such as Figure 1-5 As shown, a guide block 13 is fixedly connected to one side of the sliding rod 7 relative to the nested cylinder 2. The nested cylinder 2 has a guide groove on the inner wall of the groove, and the guide block 13 is slidably disposed on the inner wall of the guide groove.
[0029] The guide block 13 slides along the inner wall of the guide groove, which can improve the stability of the movement of the slide rod 7 and prevent the slide plate 7 from deviating and affecting the use of the elastic shock absorber 8.
[0030] 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.
