[0002] Various fitness equipment commonly available on the market, such as bicycle fitness equipment, arm training equipment, etc., are expensive to purchase and are quite large in size, and are not very suitable for use in ordinary households.

[0003] Dumbbell is a simple equipment used to enhance muscle strength training. It is used for muscle strength training and muscle compound movement training.

[0004] Most of the dumbbells currently on the market use a threaded connection to fix the dumbbell plates on the dumbbell bar, which is not convenient for disassembly and assembly. There are many types of dumbbells. When the training volume is large, multiple dumbbell plates will be assembled and used. However, in the process of assembly and disassembly, since the dumbbell plates have no connection structure, the user is generally required to first stand up the No. 1 dumbbell plate and hold it with one hand, and then pass the threaded head set at one end of the grip cross bar through the middle of the No. 1 dumbbell plate. After passing through, multiple steps are required to put another No. 1 dumbbell plate on the other end, so as to form a preliminary shaped barbell shape, and then the remaining dumbbell plates can be manually put on one by one. The steps are relatively cumbersome and inconvenient, resulting in a waste of time during use, and it is not convenient for people to use. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a technical solution: comprising an auxiliary component 1, a limit component 2 is fixedly installed at the middle of the top of the auxiliary component 1, a dumbbell component 3 is placed above the auxiliary component 1 and the limit component 2, the auxiliary component 1 comprises a bottom plate 101, a baffle 102 is fixedly installed at the middle of the edges of both sides of the top surface of the bottom plate 101, a sliding column 103 is fixedly installed between the two baffles 102, a bearing platform 104 is slidably sleeved on both ends of the column body of the sliding column 103, an arc groove 105 is opened on the top surface of the bearing platform 104, and an arc embedded groove 106 is opened in the middle of the arc groove 105;

[0023] The limiting assembly 2 includes an arch frame 201, a mounting groove 202 is provided in the middle of the top surface of the arch frame 201, a round shaft 203 is rotatably mounted on the top surface of the arch frame 201 at one side of the mounting groove 202, a rotating plate 204 is fixedly mounted on the top of the rotating plate 203, a threaded rod 205 is threadedly inserted on the side of the top surface of the rotating plate 204 away from the round shaft 203, and a limiting pressure head 206 is rotatably mounted on the bottom end of the threaded rod 205;

[0024] The dumbbell assembly 3 includes a grip bar 301, and a blocking ring 302 is fixedly sleeved at both ends of the grip bar 301. A threaded head 303 is fixedly installed at both ends of the grip bar 301, and a dumbbell piece No. 1 304, a dumbbell piece No. 2 305, and a dumbbell piece No. 3 306 are sleeved on the threaded head 303 in sequence from the inside to the outside. The top of the back of the dumbbell piece No. 1 304 and the dumbbell piece No. 2 305 is provided with a plurality of oblique insertion openings 307, and the top of the front of the dumbbell piece No. 2 305 and the dumbbell piece No. 3 306 is fixedly installed.

[0025] The middle part of the shaft of the grip bar 301 is placed in the placement groove 202 , the bottom of the limiting pressure head 206 is in conflict with the shaft of the grip bar 301 , and the first dumbbell piece 304 is embedded in the corresponding arc-shaped embedding groove 106 .

[0026] In this embodiment, a plurality of the oblique inserts 308 correspond one to one with a plurality of the oblique sockets 307 , and the oblique inserts 308 are movably inserted into the corresponding oblique sockets 307 , and the subsequent barbell plates and the first dumbbell plate 304 can be assembled and connected first through the plurality of oblique inserts 308 and the plurality of oblique sockets 307 .

[0027] At the same time, the two bases of the arch frame 201 are fixedly connected to the front and rear edges of the middle part of the top surface of the base plate 101 respectively.

[0028] The two bearing platforms 104 are also slidably connected to the top surface of the bottom plate 101. The two bearing platforms 104 are manually pushed, and the sliding of the bearing platforms 104 can drive the two sets of dumbbell plates to move and finally be sleeved on the threaded head 303 without alignment.

[0029] The outer ends of the two threaded heads 303 are both threadedly sleeved with a locking nut 309, and the inner side of the locking nut 309 abuts against the outer side of the third dumbbell plate 306. The locking nut 309 can prevent the dumbbell plate from detaching from the two ends of the grip cross bar 301.

[0030] The inner side surface of the first dumbbell piece 304 is tightly attached to the outer side surface of the resistance ring 302 , and the resistance ring 302 can play a limiting role.

[0031] The three dumbbell pieces 305 are then inserted into the three oblique slots 307 on the back of the first dumbbell piece 304, and the second dumbbell piece 306 is then hung on the back of the first dumbbell piece 304. The above operation can be repeated to hang the third dumbbell piece 305 on the back of the second dumbbell piece 305, and the assembly of the dumbbell pieces is completed. The crossbar 301 is then taken out and placed on the mounting groove 202, and the rotating plate 204 is then rotated to make it located above the crossbar 301, and the threaded rod 205 is then rotated, and the rotation of the threaded rod 205 can drive the bottom end thereof to rotate. The installed limiting pressure head 206 descends, and the gripping cross bar 301 can be fixed in the mounting groove 202 by controlling the limiting pressure head 206 to descend and contact with the surface of the gripping cross bar 301. After fixation, the two supporting platforms 104 are manually pushed, and the sliding of the supporting platforms 104 can drive the two sets of dumbbell plates to move and finally be sleeved on the threaded heads 303 without alignment. After sleeved, the locking nut 309 can be manually threaded on the outer ends of the corresponding threaded heads 303. When disassembly is required later, the two No. 1 dumbbell plates 304 are still placed in the corresponding arc-shaped grooves 106, and then the locking nut 309 is manually removed. After removal, the supporting platform 104 is directly pulled outward. The movement of the supporting platform 104 can drive the corresponding barbell group placed thereon to detach from the gripping cross bar 301, thereby completing the disassembly of the dumbbells. Note that during the disassembly process, the packaging oblique socket 307 needs to be in a high position.

[0032] To sum up, the dumbbell which is easy to assemble and disassemble can assemble multiple dumbbell plates together in advance by setting a plurality of oblique inserts and oblique inserts, so that they can be directly assembled with the grip cross bar in the form of groups, and they can be pushed to dock by auxiliary components and limit components. Multiple barbell plates can be assembled at one time without the need for individual serial connection, which effectively reduces the time for the alignment and serial connection steps of the dumbbell plates and the grip cross bar, improves the assembly efficiency, and at the same time the entire dumbbell set can be conveniently disassembled, which is more practical.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
