[0062] Please refer to Figure 1 and Figure 2, an embodiment of the present utility model provides an adjustable dumbbell 100, which includes a body 1, a counterweight assembly 2 provided at both ends of the body 1, and an adjustment assembly 3 provided on the counterweight assembly 2;

[0063] The adjustment assembly 3 includes a sliding plate 31 and a positioning assembly 32. A sliding groove 321 is provided in the positioning assembly 32. The sliding plate 31 is slidably provided in the sliding groove 321. A through groove 21 is provided on the counterweight assembly 2. An opening corresponding to the through groove 21 (not marked in the figure) is provided at the end of the sliding groove 321. The sliding plate 31 can slide through the opening and enter the through groove 21;

[0064] An adjustment channel 322 parallel to the sliding groove 321 and communicating the sliding groove 321 with the outside is provided on the positioning assembly 32. A plurality of concave positions 323 distributed along the length direction of the positioning assembly 32 are provided on the side surface of the adjustment channel 322;

[0065] An activity handle 311 exposed through the adjustment channel 322 or the concave positions 323 is provided on the sliding plate 31. The activity handle 311 can move within the adjustment channel 322 or between the adjustment channel 322 and the concave positions 323.

[0066] It can be understood that the adjustable dumbbell 100 provided by the embodiment of the present utility model can conveniently adjust the weight of the counterweight assembly 2 through the cooperation of the positioning assembly 32 and the through groove 21, and the operation is very simple.

[0067] Specifically, the sliding plate 31 provided in the sliding groove 321 can slide on the sliding groove 321 in the positioning assembly 32 and the through groove 21 on the counterweight assembly 2. The sliding plate 31 can slide through the opening provided at the end of the sliding groove 321 and enter the through groove 21. An activity handle 311 is provided on the sliding plate 31.

[0068] Furthermore, by providing an adjustment channel 322 parallel to the sliding groove 321 and communicating the sliding groove 321 with the outside, a plurality of concave positions 323 distributed along the length direction of the positioning assembly 32 are provided on the side surface of the adjustment channel 322. The activity handle 311 provided on the sliding plate 31 passes through the adjustment channel 322 or the concave positions 323 and is exposed. Among them, the activity handle 311 can move within the adjustment channel 322 or between the adjustment channel 322 and the concave positions 323.

[0069] It should be noted that the counterweight assembly 2 of the adjustable dumbbell 100 includes a plurality of dumbbell plates. When the adjustable dumbbell 100 needs to adjust the number of dumbbell plates to achieve the adjustment of the dumbbell weight, taking the example of increasing the number of dumbbell plates, by controlling the movement of the activity handle 311 within the adjustment channel 322, at this time, the sliding plate 31 passes through the opening and enters the through groove 21 on the counterweight assembly 2 to limit the disassembly and replacement of the dumbbell plates.

[0070] After the weight of the adjustable dumbbell 100 is adjusted and before starting the workout, at least a part of the slide plate 31 passes through the opening and enters the through slot 21 on the weight component 2. At this time, the control movable handle 311 moves from the adjustment channel 322 to the recess 323, and the sliding of the slide plate 31 is restricted by the movable handle 311 located in the recess 323, so as to realize the relative fixation between the slide plate 31 and the dumbbell plate.

[0071] Furthermore, it should be noted that for the adjustable dumbbell 100 provided by the embodiment of the present utility model, whether the movable handle 311 is located in the recess 323 or in the adjustment channel 322, there is a vertical engagement of the dumbbell plates of the adjustable dumbbell 100.

[0072] The present utility model designs the adjustment component 3 provided on the weight component 2 in the adjustable dumbbell 100, and the adjustment component 3 cooperates with the weight component 2 to realize the fixed engagement between the slide plate 31 and the dumbbell plate. Furthermore, when using the adjustable dumbbell 100, it is possible to avoid the situation that components such as the dumbbell plate and the slide plate 31 are separated or dropped, and solve the technical problems of the complex weight adjustment method of the existing dumbbell and the cumbersome operation of disassembling, assembling and replacing the dumbbell plate.

[0073] In some embodiments, for the adjustment component 3 provided on the weight component 2, the slide plate 31 thereon can enter the through slot 21 of the weight component 2 through the opening at the end of the chute 321, and the adjustable dumbbell 100 is symmetric in structure; therefore, in the preferred embodiment of the embodiment of the present utility model, the number of the adjustment components 3 is preferably two, and each adjustment component 3 only controls one weight component 2.

[0074] Please refer to Figure 2 and Figure 3 , the weight component 2 includes a fixed weight plate 22 and a plurality of movable weight plates 23, and the fixed weight plate 22 is respectively connected to the body 1 and the positioning component 32.

[0075] It can be understood that the fixed weight plate 22 is a dumbbell plate provided at the end of the body 1 and connected and fixed to the body 1. The movable weight plates 23 are arranged on the side of the fixed weight plate 22 away from the body 1, and the connection methods between the movable weight plates 23 and the fixed weight plate 22 and between adjacent movable weight plates 23 are all detachable connections.

[0076] In the embodiment of the present utility model, the number of the fixed weight plates 22 is two, and they are respectively arranged at the ends on both sides of the body 1; among them, the fixed weight plate 22 is connected to the body 1, and the fixed weight plate 22 can be locked to the end of the body 1 by using a threaded member (not marked in the figure) to realize the detachable connection between the fixed weight plate 22 and the body 1, or the fixed weight plate 22 can be directly welded to the end of the body 1 to realize the connection between the fixed weight plate 22 and the body 1.

[0077] Further, fixing structures 324 are provided at both ends of the positioning component 32. In this embodiment, threaded members can be used to lock the fixing structures 324 on the positioning component 32 in the first through slots 211 on the fixed counterweight sheet 22. In addition, the fixing structures 324 can also be directly welded to the first through slots 211 on the fixed counterweight sheet 22 to lock the positioning component 32 and the fixed counterweight sheet 22. It can be understood that the implementation manners of this embodiment cannot be used to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the principles of the present invention shall be included within the protection scope of the present invention.

[0078] In some embodiments, the detachable connection manners between adjacent movable counterweight sheets 23 and the fixed counterweight sheet 22, and between adjacent movable counterweight sheets 23 include, but are not limited to, snap connection, bolt connection, and threaded connection, which can be specifically set according to actual situations. As a preferred implementation manner of the embodiment of the present invention, the connection manner of detachable connection between the movable counterweight sheet 23 and the fixed counterweight sheet 22 and between adjacent movable counterweight sheets 23 is snap connection.

[0079] When installing the dumbbell plates on the adjustable dumbbell 100, first connect the first movable counterweight sheet 23 to the fixed counterweight sheet 22, and then starting from the second movable counterweight sheet 23, the movable counterweight sheets 23 are stacked in sequence. The detachable connection manner enables several movable counterweight sheets 23 to be stacked in sequence and fixed in the length direction of the adjustable dumbbell 100.

[0080] It should be noted that the connection between the movable counterweight sheet 23 and the fixed counterweight sheet 22 and between adjacent movable counterweight sheets 23 is detachable, which makes it more convenient and faster for the dumbbell user to disassemble, install, take and place the dumbbell plates when increasing or decreasing the weight of the adjustable dumbbell 100.

[0081] In the counterweight assembly 2 provided by the embodiment of the present invention, the fixed counterweight sheets 22 are respectively arranged at both ends of the body 1. Among them, the connection between the fixed counterweight sheet 22 and the body 1 ensures that there is no random movement between the fixed counterweight sheet 22 and the body 1, and thus plays a role in stably installing the movable counterweight sheet 23.

[0082] In some embodiments, the fixed counterweight sheet 22 is also connected to the positioning component 32 at the same time. Through this design, after the movable counterweight sheet 23 is installed, the adjusting component 3 and the counterweight assembly 2 can cooperate to realize the fixed snap connection between the sliding plate 31 and the movable counterweight sheet 23.

[0083] The number of the fixed counterweight sheets 22 provided by the embodiment of the present invention is two, and they are respectively arranged at both ends of the body 1.

[0084] Further, it should be noted that if the two ends of the body 1 are not connected to the fixed counterweight piece 22, when the adjustable dumbbell 100 needs to be used and the movable counterweight piece 23 is installed on either side of the two ends of the body 1 while the movable counterweight piece 23 is not installed on the other side, the body 1 will form an inclined angle with the bottom surface on which the adjustable dumbbell 100 is placed. Therefore, it is rather troublesome to install the movable counterweight piece 23 at the end of the body 1 where the movable counterweight piece 23 is not installed.

[0085] Further, please continue to refer to Figure 2 and Figure 3 , the through slot 21 includes a first through slot 211 provided on the fixed counterweight piece 22 and a second through slot 212 provided on the movable counterweight piece 23, and the first through slot 211 communicates with the second through slot 212; after the sliding plate 31 slides through the opening, it sequentially passes through the first through slot 211 and the second through slot 212.

[0086] It can be understood that in the embodiments of the present invention, by increasing or decreasing the number of movable counterweight pieces 23 installed on the adjustable dumbbell 100, the weight of the adjustable dumbbell 100 can be adjusted.

[0087] Among them, every time the sliding plate 31 on the adjusting assembly 3 enters a second through slot 212, it can be snap-fitted with the movable counterweight piece 23 corresponding to this second through slot 212.

[0088] In some embodiments, the first through slot 211 is opened on the outer side edge of the fixed counterweight piece 22, and the second through slot 212 is opened on the outer side edge of the movable counterweight piece 23 and corresponds to the position of the first through slot 211 to achieve the communication between the first through slot 211 and the second through slot 212.

[0089] It should be noted that after the sliding plate 31 slides through the opening, it first reaches the first through slot 211, and then further slides to reach the second through slot 212 communicated with the first through slot 211. By the sliding of the sliding plate 31, the movable counterweight piece 23 is limited in its vertical direction.

[0090] In some embodiments, the fixed counterweight piece 22 is connected to the positioning assembly 32 through the first through slot 211 opened thereon. Through this design, the limiting effect of the sliding plate 31 on the movable counterweight piece 23 can be improved. Since the sliding plate 31 can slide through the first through slot 211 and the second through slot 212 in sequence, by fixing the positioning assembly 32 in the first through slot 211, the loosening or even separation between the positioning assembly 32 and the fixed counterweight piece 22 can be avoided, so as not to affect the limiting effect of the sliding plate 31 on the movable counterweight piece 23 in the vertical direction.

[0091] Please refer to Figures 2 to 4 、 Figure 9The movable handle 311 includes a connected slider 3111 and a rod body 3112; one end of the slider 3111 away from the rod body 3112 is slidably connected to the slide plate 31, the inner diameter of the rod body 3112 matches the inner diameter of the recess 323, and the rod body 3112 passes through the adjustment channel 322 or the recess 323 and is exposed.

[0092] It can be understood that the movable handle 311 includes a slider 3111 and a rod body 3112 connected to the slider 3111, wherein the slider 3111 can slide on the slider 31, specifically, a sliding connection with the slider 31 is achieved through a vertical slide groove 313 opened in the notch 312 of the slider 31, and the slider 3111 can slide in and out of the recess 323 along the vertical slide groove 313, and the rod body 3112 located at the other end of the slider 3111 is exposed after passing through the adjustment channel 322 or the recess 323.

[0093] It should be noted that the rod body 3112 on the movable handle 311 is exposed after passing through the adjustment channel 322 or the recess 323, and the inner diameter of the rod body 3112 matches the inner diameter of the recess 323. By moving the rod body 3112, the movable handle 311 can be moved in the adjustment channel 322 or between the adjustment channel 322 and the recess 323.

[0094] In some embodiments, the slider 3111 is controlled by the rod body 3112, and the slider 3111 drives the slide plate 31, so that the slide plate 31 slides relative to the slide groove 321 in the slide groove 321; when the weight of the adjustable dumbbell 100 needs to be adjusted, the rod body 3112 can be moved from the recess 323 to the adjustment channel 322, and the rod body 3112 is exposed after passing through the adjustment channel 322.

[0095] At this time, the rod body 3112 is located in the adjustment channel 322 , and the rod body 3112 can move back and forth in the length direction of the adjustment channel 322 , that is, by pushing the rod body 3112 to one end close to the first through slot 211 or away from the first through slot 211 .

[0096] As an example, when the rod body 3112 gradually moves toward the first through slot 211, the slide plate 31 also passes through the opening at the end of the slide slot 321 at the speed of the rod body 3112, and passes through the first through slot 211 and the second through slot 212 in sequence.

[0097] It should be noted that no matter how the rod body 3112 moves and drives the slide plate 31 to slide along, at least a portion of the slide plate 31 is located inside the slide groove 321. This is because the adjustment channel 322 is set on the positioning assembly 32 and is parallel to the slide groove 321, so that the rod body 3112 can slide on the adjustment channel 322. Through this design, the fixing effect of the rod body 3112 can be improved, and then when the rod body 3112 is used to assist in adjusting the weight of the adjustable dumbbell 100, the rod body 3112 is prevented from detaching or even falling from the exposed adjustment channel 322, which affects the overall life of the adjustable dumbbell 100.

[0098] Among them, there are several situations for the position of the slide plate 31: the slide plate 31 may be located in the slide groove 321 as a whole, or a part of the slide plate 31 may be located in the slide groove 321 and another part may be located in the first through groove 211, and parts of the slide plate 31 may also be located in the slide groove 321, the first through groove 211 and the second through groove 212 at the same time.

[0099] In some embodiments, the portion of the slide plate 31 located in the first through slot 211 and the second through slot 212 can be fixed in position with the through slot 21 to limit and fix the movable weight plate 23 in the vertical direction of the adjustable dumbbell 100 .

[0100] After the weight of the adjustable dumbbell 100 is adjusted, the rod 3112 can be moved from the adjustment channel 322 to the recess 323. At this time, the rod 3112 is exposed after passing through the recess 323, and the position of the rod 3112 is fixed by the recess 323, and then the position of the slide plate 31 is also fixed at the same time.

[0101] See also Figure 2 , Figure 3 and Figure 4 The adjustment component 3 also includes a positioning column 33 slidably disposed in the slide groove 321, and an elastic member 34 is provided between the movable handle 311 and the positioning column 33, and the two ends of the elastic member 34 respectively abut the movable handle 311 and the positioning column 33; one end of the positioning column 33 away from the elastic member 34 abuts against the inner wall of the slide groove 321.

[0102] In some embodiments, a notch 312 is provided at the lower end of the skateboard 31, and the movable handle 311, the elastic member 34 and the positioning column 33 are installed in a vertical slide groove 313 opened in the notch 312, wherein the notch 312 is provided at the lower end of the skateboard 31 to provide a placement space for the positioning column 33; it can be understood that opening the notch 312 and setting the vertical slide groove 313 on the skateboard 31 can make the installation of the movable handle 311, the elastic member 34 and the positioning column 33 more convenient.

[0103] In some embodiments, the vertical slot 313 in the slide plate 31 is shaped as follows: Figure 9As shown, the vertical slide groove 313 connected to the notch 312 includes a first portion 3131 and a second portion 3132, the shape and size of the first portion 3131 are adapted to the slider 3111 on the movable handle 311, and the shape and size of the second portion 3132 are adapted to the elastic member 34 and the positioning column 33; when installing the movable handle 311, the elastic member 34 and the positioning column 33, the slider 3111 is first placed in the first portion 3131 of the vertical slide groove 313, and then the elastic member 34 and the positioning column 33 are placed in the second portion 3132 in turn to achieve installation. After the above parts are installed, the slide plate 31 is placed in the slide groove 321 through the end opening of the slide groove 321, and finally, the rod body 3112 passes through the slide groove 321 or the recess 323 and is connected to the slider 3111 located inside the notch 312, wherein the rod body 3112 is specifically screwed into the hole opened on the surface of the slider 3111 through a thread opened near one end of the slider 3111.

[0104] It can be understood that the movable handle 311 , the elastic member 34 and the positioning column 33 of the embodiment of the utility model are arranged in sequence, and the movable handle 311 and the positioning column 33 are respectively supported by the two ends of the elastic member 34 .

[0105] The movable handle 311 abuts against the inner bottom wall of the slide groove 321, and one end of the positioning column 33 away from the elastic member 34 abuts against the inner side wall of the slide groove 321. The movable handle 311 is controlled to move from the recess 323 to the adjustment channel 322 by moving the rod body 3112 on the movable handle 311. When the movable handle 311 moves to the adjustment channel 322, the movable handle 311 and the positioning column 33 can slide in the length direction of the slide groove 321.

[0106] Specifically, the elastic member 34 and the slider 3111 on the movable handle 311 abut against each other; when the elastic member 34 is not deformed or is slightly deformed, the elastic member 34 located between the movable handle 311 and the positioning column 33 can abut the movable handle 311 and the positioning column 33 to the opposite inner walls in the slide groove 321. At this time, the rod body 3112 on the movable handle 311 is exposed from the recess 323.

[0107] Furthermore, when the rod body 3112 is moved from the recessed position 323 to the adjustment channel 322, the elastic member 34 is significantly deformed. At this time, the rod body 3112 on the movable handle 311 is exposed from the adjustment channel 322. By arranging the elastic member 34 between the movable handle 311 and the positioning column 33, it is possible to adjust the weight of the adjustable dumbbell 100 or change the number of movable weight plates 23 by applying a certain force to move the rod body 3112 in order to move the rod body 3112 to the adjustment channel 322, thereby preventing the movable weight plates 23 from falling off due to accidental touching of the rod body 3112 on the movable handle 311.

[0108] In some embodiments, if the rod 3112 on the movable handle 311 is toggled from the concave position 323 to the adjustment channel 322 and then the rod 3112 is released and the toggling of the rod 3112 is stopped without adjusting the number of movable counterweight pieces 23, the force of the elastic member 34 to restore deformation will act on the slider 3111 on the movable handle 311. The slider 3111 drives the rod 3112 to move from the adjustment channel 322 to the concave position 323, and the rod 3112 is engaged with the exposed concave position 323 to limit the movement of the movable handle 311.

[0109] Please refer to Figure 2 、 Figure 4 and Figure 5 , a positioning bead 331 is provided at one end of the positioning post 33 away from the elastic member 34. A plurality of positioning holes 332 corresponding to the positioning bead 331 are provided on the inner side wall of the chute 321 in the length direction. The positioning bead 331 abuts against the inner side wall of the chute 321 or the positioning holes 332; when the positioning bead 331 slides and engages with the positioning holes 332, the movable handle 311 is exposed through the concave position 323.

[0110] It can be understood that the positioning bead 331 is provided at one end of the positioning post 33 away from the elastic member 34 to realize the limit sliding of the positioning post 33 relative to the inner side wall of the chute 321. When the rod 3112 is toggled from the concave position 323 to the adjustment channel 322, the elastic member 34 will undergo obvious deformation. At this time, a certain force can be applied to toggle the rod 3112 to move to the adjustment channel 322, and by continuously applying this force, the movable handle 311 can move freely in the adjustment channel 322. At the same time, the positioning post 33 also slides in the length direction of the inner side wall of the chute 321 through the positioning bead 331.

[0111] At the same time, positioning holes 332 that cooperate with the positioning bead 331 are also provided on the inner side wall of the chute 321. The positioning holes 332 are arranged along the length direction of the inner side wall of the chute 321, and the cooperation between the positioning bead 331 and the positioning holes 332 is realized on the inner side wall of the chute 321.

[0112] Through this design in the embodiments of the present utility model, the movement of the movable handle 311 can drive the movement of the sliding plate 31 in the chute 321 more stably, improve the use experience of the dumbbell by the user, and extend the service life of the dumbbell.

[0113] It should be noted that the positioning post 33 can slide relative to the chute 321 and is fixed to the positioning holes 332 through the positioning beads 331, converting from stepless movement to stepped movement.

[0114] Specifically, during the process of adjusting the weight of the dumbbell, when the positioning post 33 drives the slider provided on the elastic member 34 to slide until the positioning bead 331 is connected to the positioning hole 332, a vibration damping sensation of "click" will occur, indicating that the positioning bead 331 has been fixed in the positioning hole 332. At this time, the positioning post 33 is fixed in the chute 321, and the elastic member 34 and the movable handle 311 connected to the positioning post 33 are also fixed accordingly.

[0115] It should be further noted that when the movable handle 311 is toggled, while the movable handle 311 drives the sliding plate 31 to slide, it also drives the elastic member 34 and the positioning post 33 to move together. The vibration damping sensation generated when the positioning post 33 slides until the positioning bead 331 is connected to the positioning hole 332 is achieved through a small deformation of the positioning bead 331.

[0116] Please refer to Figure 4 and Figure 6 The chute 321 is connected to the first through slot 211 provided on the fixed counterweight 22. Among them, the positioning assembly 32 is connected to the fixed counterweight 22. Specifically, an opening corresponding to the through slot 21 is provided at the end of the chute 321, and the chute 321 is connected to the first through slot 211 through the opening.

[0117] Furthermore, the main body 1 includes a grip rod 11 and fixing plates 12 respectively sleeved at both ends of the grip rod 11. A card slot 111 is provided on the grip rod 11. One side of the fixing plate 12 abuts against the inner side wall of the card slot 111, and the other side is detachably connected to the fixed counterweight 22.

[0118] In the embodiment of the present utility model, the main body 1 includes a grip rod 11 for the dumbbell user to hold the adjustable dumbbell 100 during fitness, and fixing plates 12 respectively sleeved at both ends of the grip rod 11. The card slot 111 opened on the grip rod 11 is responsible for limiting the fixing plate 12. Among them, the fixing plate 12 is arranged between the fixed counterweight 22 and the inner side wall of the card slot 111 on the side away from the fixed counterweight 22, and the fixing plate 12 is limited and fixed through the card slot 111 located on the grip rod 11.

[0119] It should be noted that the card slot 111 on the grip rod 11 is specifically arranged in a circle around the outer peripheral surface of the grip rod 11, and the inner side wall of the card slot 111 faces the fixed counterweight 22.

[0120] When the fixing plate 12 is sleeved and installed on the grip rod 11, the fixing plate 12 is placed in the card slot 111. One side of the fixing plate 12 is abutted by the inner side wall of the card slot 111, and the other side is fixed to the fixed counterweight 22.

[0121] In some embodiments, to achieve the purpose of more convenient disassembly, replacement of the fixed plate 12 according to the needs of the dumbbell user, the fixed plate 12 can be designed in a shape such as "π", which can avoid the positioning component 32 installed on the fixed counterweight 22.

[0122] Among them, the weight of the fixed plate 12 is smaller than that of the movable counterweight 23, which greatly improves the flexibility of adjusting the weight of the adjustable dumbbell 100.

[0123] In some embodiments, the detachable connection between the fixed plate 12 and the fixed counterweight 22 can be a snap connection, a pin locking connection, a bolt mating connection, or other connection methods. That is to say, the specific implementation of this embodiment cannot be used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the principle of the present invention should be included in the protection scope of the present invention.

[0124] Please refer to Figure 10 , as a preferred implementation of the embodiment of the present invention, the installation of the fixed plate 12 is achieved by pin locking between the fixed plate 12 and the fixed counterweight 22. Specifically, a fixing hole 121 for the pin member 13 to pass through is formed on the fixed plate 12, and a hole passage 221 matching the pin member 13 is provided on the fixed counterweight 22. The pin member 13 passes through the fixing hole 121 from the side of the fixed plate 12 facing away from the fixed counterweight 22 and is inserted into the hole passage 221 for cooperation to lock the fixed plate 12 and the fixed counterweight 22; conversely, pulling the pull ring 131 provided at the end of the pin member 13 and rotating the pin member 13 can unlock the pin member 13 from the hole passage 221 to unlock and separate the fixed plate 12 and the fixed counterweight 22.

[0125] Please refer to Figure 1 , Figure 6 and Figure 7 , the counterweight assembly 2 further includes a dovetail protrusion 24, and a dovetail groove 25 matching the dovetail protrusion 24 is formed on one side of the movable counterweight 23, and the dovetail protrusion 24 is inserted into the dovetail groove 25.

[0126] In some embodiments, the movable counterweight 23 is clamped and limited by the dovetail protrusion 24 with the adjacent fixed counterweight 22 or movable counterweight 23, and the width of the top of the dovetail protrusion 24 is not less than the width of the bottom.

[0127] It can be understood that the embodiment of the present invention provides a dovetail protrusion 24 and a dovetail groove 25 matching the dovetail protrusion 24 on one side of the movable counterweight 23, which can realize the limit fixation in the length direction of the adjustable dumbbell 100 between adjacent movable counterweights 23 and between the fixed counterweight 22 and the movable counterweight 23.

[0128] It should be noted that the dovetail groove 25 formed on the movable counterweight piece 23 is used for inserting the dovetail projection 24. The dovetail projection 24 can engage and limit the adjacent fixed counterweight piece 22 or movable counterweight piece 23. Among them, for the dovetail projection 24 and the corresponding dovetail groove 25, the width of the top is not less than that of the bottom. Through this design, the dovetail projection 24 can be pulled towards its top until the dovetail projection 24 is separated from the dovetail groove 25, and then the corresponding movable counterweight piece 23 can be quickly and conveniently lifted upwards and taken out.

[0129] In the implementation scheme provided by the embodiment of the present utility model, the adjacent movable counterweight pieces 23 and between the adjacent fixed counterweight piece 22 and the movable counterweight piece 23 are fixed in the length direction of the adjustable dumbbell 100 through the cooperation of the dovetail projection 24 and the dovetail groove 25.

[0130] Specifically, in some embodiments, for the adjacent fixed counterweight piece 22 and the movable counterweight piece 23, the dovetail groove 25 is formed on the side of the movable counterweight piece 23 facing the fixed counterweight piece 22. The dovetail projection 24 is inserted downwards from the top of the movable counterweight piece 23 into the dovetail groove 25, and a connecting structure (not marked in the figure) is provided at one end of the dovetail projection 24 departing from the dovetail groove 25. The connecting structure is connected to a connecting hole (not marked in the figure) formed on the fixed counterweight piece 22.

[0131] It can be understood that the cooperation mode of the dovetail projection 24 and the dovetail groove 25 between the adjacent movable counterweight pieces 23 is the same. Through this design, the axial positioning of the movable counterweight piece 23 can be realized, so that the movable counterweight pieces 23 do not move relative to each other, preventing the dislocation between the dumbbell pieces in the adjustable dumbbell 100, and having relatively high safety and stability.

[0132] Among them, the connecting structure provided on the dovetail projection 24 and the connecting hole on the fixed counterweight piece 22 or the movable counterweight piece 23 can be designed according to actual requirements, which will not be elaborated here.

[0133] In some embodiments, there may be differences in weight between the movable counterweight pieces 23. Generally, factors such as age group and gender determine that the strength of each dumbbell user may be different. If the weight of each dumbbell piece, that is, the movable counterweight piece 23, is the same, it may not be possible to find a dumbbell weight suitable for each user by fine-tuning the weight.

[0134] As an example, if the weight of each movable counterweight piece 23 is 2 kg, then in order to ensure that the weights at both ends of the adjustable dumbbell 100 are the same, the minimum weight of the adjustable dumbbell 100 is 4 kg, and if it is heavier, it reaches 8 kg, which cannot meet the needs of dumbbell users who need 6 kg. Therefore, the way provided by the embodiment of the present utility model to solve this problem is to set movable counterweight pieces 23 with different weights.

[0135] Please refer to Figure 8 , an embodiment of the present utility model further provides a dumbbell assembly 200, which includes a base 4 and a dumbbell disposed on the base 4. The dumbbell is the adjustable dumbbell 100 described above.

[0136] It can be understood that the dumbbell assembly 200 provided by the embodiment of the present utility model can meet the requirements of storing the adjustable dumbbell 100 in a non-use state and facilitating disassembly and assembly during use by providing a base 4 on the adjustable dumbbell 100.

[0137] It should be noted that when the adjustable dumbbell 100 is placed on the base 4 and its weight is adjusted, such as adding or removing dumbbell plates and replacing dumbbell plates of different weights, it will be more convenient and faster, greatly saving the time and effort required for disassembly and assembly.

[0138] In some embodiments, the base 4 is made of metal, which can well protect the adjustable dumbbell 100 and prevent the adjustable dumbbell 100 from being collided from the outside, thereby affecting the service life of the adjustable dumbbell 100.

[0139] It should be noted that the dumbbell assembly 200 provided by the embodiment of the present utility model has the same beneficial effects as the above-mentioned adjustable dumbbell 100.

[0140] Please continue to refer to Figure 8 , in some embodiments, the dumbbell assembly 200 further includes a bearing plate 5 located between the base 4 and the counterweight assembly 2. The bearing plate 5 is used to bear the counterweight assembly 2.

[0141] Specifically, the bearing plate 5 is disposed on opposite sides of the base 4 and is detachably connected to the base 4.

[0142] It can be understood that when the adjustable dumbbell 100 is in a non-use state, the bearing plate 5 is located between the base 4 and the counterweight assembly 2 on the adjustable dumbbell 100, and the bearing plate 5 plays a supporting role for the counterweight assembly 2.

[0143] It should be noted that the bearing plate 5 provided by the embodiment of the present utility model is specifically a nylon plate. The nylon plate can better prevent the counterweight assembly 2 on the adjustable dumbbell 100 from directly hitting the base. Through this design, the service life of the adjustable dumbbell 100 can be extended while protecting the adjustable dumbbell 100.

[0144] Please continue to refer to Figure 8 , in some embodiments, the dumbbell assembly 200 further includes a support frame 6 detachably connected to the base 4. At least part of the support frame 6 is respectively disposed at one end of the counterweight assembly 2 away from the body 1.

[0145] Understandably, the support frame 6 provided in the embodiment of the present utility model can limit and support the end of the counterweight assembly 2 away from the main body 1, thereby ensuring that when adding, reducing, or replacing dumbbell plates of different weights to the adjustable dumbbell 100, the dumbbell plates will not fall out from the support frame 6 fixed at both ends of the base 4. This structure also facilitates the adjustment of the weight of the adjustable dumbbell 100.

[0146] Further, a mating hole 61 is formed in one of the base 4 and the support frame 6, and a mating member 62 corresponding to the mating hole 61 is formed in the other. A plurality of mating holes 61 or mating members 62 are provided on the base 4, and the mating hole 61 and the mating member 62 are engaged to connect and fix the base 4 and the support frame 6.

[0147] It should be noted that the base 4 and the support frame 6 are detachably connected, specifically by forming a mating hole 61 and a mating member 62 provided at the position corresponding to the mating hole 61.

[0148] In the preferred technical solution of the embodiment of the present utility model, the mating hole 61 and the mating member 62 are respectively located on the base 4 and the support frame 6, and a plurality of mating holes 61 are evenly arranged in the length direction of the base 4. The mating member 62 is engaged with the mating hole 61 to realize the snap connection between the base 4 and the support frame 6.

[0149] Among them, the mating member 62 on the support frame 6 can be engaged with these plurality of mating holes 61 on the base 4. During the use of the adjustable dumbbell 100, the dumbbell user may disassemble and assemble a part of the dumbbell plates due to the need for a larger or smaller dumbbell weight, and the weight of the counterweight assembly 2 needs to be adjusted. The mating member 62 and the mating hole 61 can ensure flexible engagement when different numbers of dumbbell plates are included in the counterweight assembly 2.

[0150] A clearance notch 63 is further provided on the support frame provided in the embodiment of the present utility model, and the clearance notch 63 provides clearance for the bearing plate 5.

[0151] As an example, when the weight of the adjustable dumbbell 100 needs to be reduced, the space occupied by the counterweight assembly 2 together with the main body 1 in the base 4 also decreases accordingly. In order to limit and support the counterweight assembly 2, the support frame 6 can engage the mating member 62 with the mating hole 61 provided near the counterweight assembly 2 on the base 4.

[0152] Of course, when the weight of the adjustable dumbbell 100 needs to be increased, the support frame 6 also needs to limit and support the counterweight assembly 2. Then, the mating member 62 can be engaged with the mating hole 61 provided far from the counterweight assembly 2 on the base 4, and the weight of the dumbbell can be increased by adding dumbbell plates or replacing dumbbell plates of different weights.

[0153] It can be understood that the connection method between the base 4 and the support frame 6 is not limited to snap connection. The mating hole 61 and the mating part 62 can also be bolted, or can be sliding limit connection. The specific connection method can be set according to the daily use requirements and preferences of the dumbbell user.

[0154] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present invention shall be included within the protection scope of the present invention.
