Description

Technical Field

[0001] This application relates to the field of sports equipment technology, specifically an integrated soft dumbbell. Background Technology

[0002] Dumbbells, as a type of fitness equipment, can help improve physical fitness by continuously lifting them.

[0003] During the use of dumbbells, accidental slips can cause the dumbbells to fall from the user's hand. Since dumbbells are usually made of metal, they can cause serious damage to the ground when they fall from a height.

[0004] Therefore, this application provides an integrated soft dumbbell to solve the above problems. Utility Model Content

[0005] This application provides an integrated soft dumbbell, which aims to solve the problems mentioned in the background art, such as the dumbbell slipping from the hand due to accidental factors, and the dumbbell being made of metal, causing serious damage to the ground after falling.

[0006] To achieve the above objectives, this application provides the following technical solution: an integrated soft dumbbell, including a grip bar; To prevent the dumbbells from damaging the ground: Symmetrical fillers are provided at both ends of the grip bar to increase the weight of the dumbbells. A loading assembly is located outside the fillers to hold them, and inside the loading assembly is a frame to maintain its shape. A mounting seat is located on the side of the loading assembly away from the grip bar for the loading assembly to move in and out. One end of the mounting seat has a sealing cap for closing it. By rotating the sealing cap, it separates from the mounting seat, allowing the filler of the corresponding weight to be poured into the loading layer to increase the weight of the dumbbells. Once the filler is filled, the sealing cap is tightened to close the mounting seat, allowing the user to lift the dumbbells for exercise. If the dumbbells accidentally fall, the shaping frame will elastically deform, and since the filler is a non-metallic solid material, it can prevent serious damage to the ground, thus protecting the floor.

[0007] Preferably, to facilitate the shaping of the loading assembly: the loading assembly includes a loading layer sleeved outside the filler to wrap the loading assembly and a protective layer sleeved outside the loading layer to protect the loading layer. The frame member is disposed between the loading layer and the protective layer, and the side of the loading layer away from the mounting base is fixedly connected to the end of the handle. By disposing the frame member between the loading layer and the protective layer, the frame member provides support and shaping for both the loading layer and the protective layer.

[0008] Preferably, to facilitate the filling of the filler: the mounting base is connected through the loading layer, and the sealing cap is threaded onto the outer wall of the mounting base. By rotating the sealing cap, the sealing cap can be separated from the mounting base, allowing the filler to be filled into the interior of the loading assembly through the mounting base, or the filler to be discharged from the interior of the loading assembly.

[0009] Preferably, to maintain the seal of the mounting base, a sealing gasket is fitted inside the sealing cover to seal the mounting base and the sealing cover. By rotating the sealing cover, the mounting base and the sealing cover continuously compress and deform the sealing gasket, thereby sealing the mounting base and the sealing cover and preventing the filler from leaking out.

[0010] Preferably, to facilitate the restoration of the loading assembly's shape: the frame component includes symmetrically arranged shaping frames inside the loading assembly for supporting the shape of the loading assembly, and connecting rods arranged between the symmetrical shaping frames for connecting the symmetrical shaping frames. When the dumbbell falls, the shaping frames deform, and as the shaping frames rebound, they return to their original shape, thereby maintaining the shape of the loading assembly.

[0011] Preferably, to maintain the weight of the grip, the interior of the grip is filled with iron filings. By filling the interior of the grip with the iron filings, the grip has sufficient weight.

[0012] This application, through the design of the filler, loading assembly, frame, mounting base, and sealing cap, fills the interior of the loading layer with the filler and seals the mounting base with the sealing cap, allowing dumbbell exercises to be performed by holding the bar. When the dumbbell is accidentally dropped, the frame and filler are made of flexible materials, thus preventing damage to the ground. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] This embodiment provides an integrated soft dumbbell, such as Figure 1-6 As shown, the dumbbell includes a handle 1; To prevent the dumbbells from damaging the ground: Symmetrical fillers 2 for increasing dumbbell weight are provided at both ends of the grip bar 1. A loading assembly 3 for holding the fillers 2 is located outside the fillers 2. A frame 4 for maintaining the shape of the loading assembly 3 is located inside the loading assembly 3. A mounting seat 5 for the loading assembly 3 to move in and out is located on the side of the loading assembly 3 away from the grip bar 1. A sealing cap 6 for closing the mounting seat 5 is located at one end of the mounting seat 5. By rotating the sealing cap 6, the sealing cap 6 is separated from the mounting seat 5, allowing the filler 2 of the corresponding weight to be poured into the loading layer 31 to increase the weight of the dumbbells. After the filler 2 is filled, the sealing cap 6 is tightened to close the mounting seat 5, allowing the user to lift the dumbbells for exercise. If the dumbbells accidentally fall, the shaping frame 41 will undergo elastic deformation. Since the filler 2 is a non-metallic solid material, it can prevent serious damage to the ground, thus achieving a protective effect on the ground.

[0017] Furthermore, the grip bar 1 is made of metal, which makes it easy to hold. The filler 2 can be water or fine sand to increase the weight of the dumbbell. Two sets of loading components 3 are symmetrically arranged at both ends of the grip bar 1. In order to maintain the consistency of the weight of the loading components 3 at both ends, the weight of the filler 2 can be weighed by an electronic scale, or the same volume and type of filler 2 can be filled.

[0018] Specifically, to facilitate the shaping of the loading assembly 3: the loading assembly 3 includes a loading layer 31 fitted over the filler 2 to wrap the loading assembly 3, and a protective layer 32 fitted over the loading layer 31 to protect it. A frame member 4 is disposed between the loading layer 31 and the protective layer 32, with the side of the loading layer 31 away from the mounting base 5 fixedly connected to the end of the handle 1. By placing the frame member 4 between the loading layer 31 and the protective layer 32, the frame member 4 provides support and shaping for the loading layer 31 and the protective layer 32. The portion of the loading layer 31 that contacts the end of the handle 1 is fixedly connected by adhesive. Both the loading layer 31 and the protective layer 32 are made of waterproof and scratch-resistant thermoplastic polyurethane. The frame member 4 is disposed between the loading layer 31 and the protective layer 32, and the junction of the frame member 4 with the portion in contact with the loading layer 31 and the protective layer 32 is fixed by spot bonding, thereby achieving a shaping effect on the loading assembly 3.

[0019] Specifically, to facilitate the filling of filler 2: the mounting base 5 is continuously connected to the loading layer 31, and the sealing cap 6 is threaded onto the outer wall of the mounting base 5. By rotating the sealing cap 6, the sealing cap 6 can be separated from the mounting base 5, allowing filler 2 to be filled into the loading assembly 3 through the mounting base 5, or to be discharged from the loading assembly 3. The mounting base 5 connects the loading layer 31 and the protective layer 32. The mounting base 5 adopts the same structure as the existing milk Tetra Pak injection ring. The mounting base 5 is bonded and fixed to the loading layer 31 and the protective layer 32 at the contact points. The threads on the outer wall of the mounting base 5 mesh with the threads on the inner wall of the sealing cap 6, so that the sealing cap 6 can be fixedly installed on the outer wall of the mounting base 5 by rotating it.

[0020] More specifically, to maintain the seal of the mounting base 5, a sealing gasket 7 is fitted inside the sealing cover 6 to seal the mounting base 5 and the sealing cover 6. By rotating the sealing cover 6, the mounting base 5 and the sealing cover 6 continuously compress and deform the sealing gasket 7, thereby sealing the mounting base 5 and the sealing cover 6 and preventing the filler 2 from leaking out. The sealing cover 6 is a circular rubber sealing ring installed inside the sealing cover 6. As the sealing cover 6 rotates, the mounting base 5 continuously approaches the sealing gasket 7 until it compresses and deforms the sealing gasket 7, thereby maintaining the seal between the mounting base 5 and the sealing cover 6.

[0021] More specifically, to facilitate the restoration of the shape of the loading assembly 3: the frame component 4 includes symmetrically arranged shaping frames 41 inside the loading assembly 3 to support the shape of the loading assembly 3, and connecting rods 42 arranged between the symmetrical shaping frames 41 to connect the symmetrical shaping frames 41. When the dumbbell falls, the shaping frames 41 will deform, and as the shaping frames 41 rebound, they will return to their original shape, thereby maintaining the shape of the loading assembly 3. Both the shaping frame 41 and the connecting rod 42 are made of elastic rubber. The parts of the shaping frame 41 and the connecting rod 42 that come into contact are bonded and fixed. When external force is applied, the shaping frame 41 undergoes elastic deformation. When the external force gradually disappears, it will return to its original shape under its own elasticity, thereby maintaining the shape of the loading component 3. Three shaping frames 41 are provided. The three shaping frames 41 are parallel to each other. Two of the shaping frames 41 are the same size, and the third shaping frame 41 is smaller than the other two shaping frames 41. The smaller shaping frame 41 is located on the side closer to the handle 1. Thus, the three shaping frames 41 are connected to each other through the connecting rod 42.

[0022] Specifically, to maintain the weight of the grip 1, iron sand 8 is placed inside the grip 1. By filling the inside of the grip 1 with iron sand 8, the grip 1 has sufficient weight. After the grip 1 is filled with iron sand 8, it is then bonded and sealed to the contact area with the loading layer 31, making the grip 1 and the loading assembly 3 non-removable.

[0023] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
