[0024] Compared with the prior art, the adjustable dumbbell provided by the utility model has the following advantages:

[0025] 1. The first embodiment of the utility model provides an adjustable dumbbell, which includes a body, a limiting structure and a movable locking assembly; the limiting structure is arranged at the end of the body, and the locking assembly is arranged on the body; a receiving channel connected to the outside is opened inside the body, at least part of the limiting structure is located in the receiving channel and is slidably connected to the body through the receiving channel; a receiving space is formed between one end of the limiting structure away from the receiving channel and the end of the body; a part of the locking assembly passes through the body and cooperates with the limiting structure located in the receiving channel.

[0026] It can be understood that the adjustable dumbbell provided in the first embodiment of the utility model can conveniently adjust the weight of the dumbbell, and the operation is very simple. Through the sliding connection between the limiting structure and the main body, a accommodating space for placing dumbbell plates is formed between the end of the limiting structure away from the accommodating channel and the end of the main body. The weight of the dumbbell plates can be configured in the accommodating space, for example, the number of dumbbell plates can be increased or decreased, and heavier or lighter dumbbell plates can be replaced.

[0027] Furthermore, the locking assembly on the adjustable dumbbell can be completed during the step of adjusting the dumbbell plates, that is, after the weight of the adjustable dumbbell is adjusted and before starting fitness, a part of the locking assembly can movably pass through the body and cooperate with the limiting structure located in the accommodating channel to achieve locking between the two.

[0028] It should be noted that the utility model designs a limiting structure of an adjustable dumbbell and a locking component that cooperates with the limiting structure, and the locking component cooperates with the limiting structure to achieve locking between the two, so that when using the adjustable dumbbell, it can avoid the situation where components such as the limiting structure and dumbbell plates are detached or dropped. Through this design, it solves the technical problem that the existing adjustable dumbbells need to install the dumbbell plates to the dumbbell rod through the conventional adjustment method and then lock the dumbbell plates through the tightening nut to achieve the weight adjustment of the dumbbell, and the operation of disassembling and replacing the dumbbell plates is very cumbersome.

[0029] 2. The adjustable dumbbell provided in the first embodiment of the utility model further includes a dumbbell plate assembly; the body includes a grip and fixed dumbbell plates arranged at both ends of the grip, and the dumbbell plate assembly is located in the accommodating space.

[0030] It can be understood that the main body includes a grip for the user of the adjustable dumbbell to hold, and fixed dumbbell plates arranged at both ends of the grip. By setting the fixed dumbbell plates, it is not necessary to spend more time and effort when adding, reducing or replacing dumbbell plates.

[0031] It should be noted that when the dumbbell plate assembly is located in the accommodating space, the dumbbell plate assembly is specifically arranged between the fixed dumbbell plate and the limiting structure. After passing through the dumbbell plate assembly and the fixed dumbbell plate, the limiting structure enters the accommodating channel and is slidably connected to the body.

[0032] 3. The adjustable dumbbell provided in the first embodiment of the utility model, the locking assembly includes a connected fixing member and a movable structure, the fixing member is detachably connected to the grip rod and / or the fixed dumbbell plate, and the movable structure can rotate relative to the fixing member so that the movable structure passes through the grip rod and abuts against the limiting structure.

The fixing member can be connected to either the grip bar or the fixed dumbbell plate, or can be connected to both of them at the same time. At this time, the fixing member is in contact with the grip bar and the fixed dumbbell plate. Through this design, the fixing effect of the locking assembly on the limiting structure can be improved, and the locking assembly can be prevented from detaching, causing the dumbbell plate assembly located between the fixed dumbbell plate and the limiting structure to separate from the body.

[0034] Furthermore, on the basis that the fixing piece is detachably connected and fixed to the main body, the movable structure can rotate relative to the fixing piece, and an opening can be set on the handle bar to allow at least a part of the movable structure to pass through the handle bar through the opening to abut against the limiting structure, so as to achieve locking between the movable structure and the limiting structure by the mutual abutment between the two.

[0035] 4. The adjustable dumbbell provided in the first embodiment of the utility model has a limiting structure including a limiting rod and a limiting member, one end of the limiting rod is connected to the limiting member, and the side of the limiting rod away from the limiting member is inserted into the accommodating channel and is slidably connected to the grip rod; the limiting member cooperates with the fixed dumbbell plate to clamp the dumbbell plate assembly.

[0036] It should be noted that, in the limiting structure, the sliding connection between the limiting structure and the grip is realized by the limiting rod, and the side of the limiting rod away from the limiting member is penetrated into the accommodating channel, the limiting rod is penetrated into the accommodating channel, and the limiting member and the fixed dumbbell plates at both ends of the grip cooperate to clamp the dumbbell plate assembly, that is, the dumbbell plate assembly is located between the limiting member and the grip.

[0037] It can be understood that at least part of the limit rod is successively passed through the dumbbell plate assembly and the fixed dumbbell plate, and finally passed through the accommodating channel to achieve the mutual cooperation between the limit rod and the limit member. Through this design, the limit rod can be locked with the movable structure of the locking assembly in the accommodating channel, and the limit member can cooperate with the fixed dumbbell plate to clamp the dumbbell plate assembly between the two.

[0038] 5. The adjustable dumbbell provided in the first embodiment of the utility model is provided with a protrusion on the movable structure, and the protrusion abuts against the limit rod after passing through the grip; the limit rod is a threaded rod, and the protrusion is provided with a matching thread adapted to the limit rod, and the protrusion cooperates with the limit rod thread after passing through the grip, or the limit rod is provided with a fixing groove corresponding to the protrusion, and the protrusion is engaged and connected with the fixing groove after passing through the grip.

[0039] It can be understood that the locking assembly of the first embodiment of the utility model includes a fixing member and a movable structure that can rotate relative to the fixing member. In the movable structure, the protrusion passes through the grip rod and then abuts against the limit rod. The abutment method between the protrusion and the limit rod includes threaded cooperation and snap-on connection.

[0040] 6. The adjustable dumbbell provided in the first embodiment of the utility model has a movable structure including a main movable part, a secondary movable part and a locking part which are arranged in sequence, and the two ends of the secondary movable part are rotatably connected with the main movable part and the locking part respectively; the main movable part is rotatably connected with the fixed part at one end away from the secondary movable part, and a protrusion is arranged on the side of the main movable part facing the fixed part.

[0041] It can be understood that in the first embodiment of the utility model, the movable structure is composed of a main movable part, a secondary movable part and a locking part connected in sequence, the main movable part is rotatably connected to the secondary movable part, and the locking part is also rotatably connected to the secondary movable part, and the protrusion is arranged on the side of the main movable part facing the fixed part. When the protrusion is not in contact with the limit rod, the two ends of the secondary movable part can be rotated with the main movable part and the locking part respectively; and when the protrusion is in contact with the limit rod, the locking part rotates relative to the secondary movable part to a locked state.

[0042] It should be noted that the fixed part is rotatably connected to the main movable part at the end away from the auxiliary movable part. By setting the connection between the fixed part and the grip bar and / or the fixed dumbbell plate to be a detachable connection, it is possible to prevent parts in the movable structure from falling, being damaged or lost when the protrusion is not abutted against the limit rod.

[0043] 7. The adjustable dumbbell provided in the first embodiment of the utility model comprises a dumbbell plate assembly including a first dumbbell plate and a second dumbbell plate, wherein the first dumbbell plate is arranged between the fixed dumbbell plate and the second dumbbell plate, and the weight of the first dumbbell plate is greater than the weight of the second dumbbell plate.

[0044] It can be understood that the dumbbell plate assembly in the first embodiment of the present invention includes a first dumbbell plate and a second dumbbell plate, and the difference between the two includes the difference in weight, wherein the weight of the first dumbbell plate is greater than the weight of the second dumbbell plate. Generally, the strength of each dumbbell user is different due to factors such as age and gender. If the weight of each dumbbell plate is the same, it is impossible to find a dumbbell weight suitable for each person by fine-tuning the weight. Therefore, the first embodiment of the present invention solves this technical problem by providing dumbbell plates of different weights.

[0045] It should be noted that in the actual application of existing adjustable dumbbells, the dumbbell pieces close to the grip are generally heavier than the dumbbell pieces far from the grip, while the weight of the dumbbell pieces far from the grip is less than or equal to the weight of the dumbbell pieces close to the grip. If the placement is opposite to the above, the actual weight of the dumbbells picked up during fitness will be heavier. The specific reason is that the force point has changed, which will not be elaborated here.

[0046] 8. The adjustable dumbbell provided in the first embodiment of the utility model has a mounting opening and a mounting groove connected to the mounting opening at the bottom of the first dumbbell plate and the second dumbbell plate, the mounting groove extends to the middle of the first dumbbell plate and the second dumbbell plate, and the width of the mounting groove is greater than the diameter of the limiting rod.

[0047] It can be understood that the first dumbbell plate and the second dumbbell plate are provided with a mounting opening at the bottom and a mounting groove in the middle, the mounting opening is connected to the mounting groove and the width of the mounting groove is greater than the diameter of the limiting rod. Through this design, the first dumbbell plate and / or the second dumbbell plate can be placed on the limiting rod through the mounting groove when the limiting rod is inserted into the accommodating channel and is slidably connected to the grip rod. The dumbbell plates can be added, reduced or replaced by only pulling the limiting member to make the limiting rod slide a certain distance toward the side away from the main body.

[0048] It should be noted that the first embodiment of the utility model provides a mounting port and a mounting groove connected to the mounting port at the bottom of the dumbbell plate, which will make it more convenient and quick to add or reduce the first dumbbell plate and the second dumbbell plate, or replace different dumbbell plates, thereby saving the time and effort spent on disassembly and assembly.

[0049] 9. The adjustable dumbbell provided in the first embodiment of the utility model has a positioning structure between adjacent fixed dumbbell plates and the first dumbbell plates or the second dumbbell plates, between adjacent first dumbbell plates, between adjacent first dumbbell plates and the second dumbbell plates, and between adjacent second dumbbell plates, and the other has a positioning groove that cooperates with the positioning structure.

[0050] It can be understood that by providing a positioning structure between the dumbbell plates and a positioning groove that cooperates with the positioning structure, when the first dumbbell plate and / or the second dumbbell plate is placed between the limiting member and the fixed dumbbell plate, the positioning structure on one of the dumbbell plates will be inserted into the positioning groove on the adjacent dumbbell plate, thereby achieving axial positioning of the dumbbell plates, so that the dumbbell plates will not move relative to each other, preventing misalignment of the dumbbell plates, and having higher safety and stability.

[0051] 10. The adjustable dumbbell provided in the first embodiment of the utility model is provided with a lifting structure and / or a weight-reducing hole on the fixed dumbbell plate, the first dumbbell plate and / or the second dumbbell plate.

[0052] It can be understood that providing a lifting structure on the dumbbell plates can save effort when adding, removing or replacing dumbbell plates, and avoid potential safety hazards that may be caused by directly picking up the dumbbell plates; and providing weight-reducing holes on the dumbbell plates can reduce costs accordingly, and achieve lightweighting of the adjustable dumbbells while meeting the weight of the dumbbell plates.

[0074] See also Figure 1 and Figure 2 The first embodiment of the utility model provides an adjustable dumbbell 100, comprising a body 1, a limiting structure 2 and a movable locking assembly 3;

[0075] The limiting structure 2 is arranged at the end of the body 1, and the locking assembly 3 is arranged on the body 1;

[0076] An accommodating channel 11 communicating with the outside is provided inside the body 1, and at least a part of the limiting structure 2 is located in the accommodating channel 11 and is slidably connected to the body 1 through the accommodating channel 11;

[0077] An accommodation space 21 is formed between one end of the limiting structure 2 away from the accommodation channel 11 and the end of the body 1;

[0078] A portion of the locking assembly 3 passes through the body 1 and cooperates with the limiting structure 2 located in the accommodating channel 11 .

[0079] It can be understood that the adjustable dumbbell 100 provided in the first embodiment of the utility model can conveniently adjust the weight of the dumbbell and is simple to operate, by setting a limiting structure 2 at the end of the main body 1, wherein the limiting structure 2 is set at both ends of the main body 1, and an accommodating channel 11 connected to the outside is opened inside the main body 1, so that at least part of the limiting structure 2 is located in the accommodating channel 11, thereby realizing a sliding connection between the limiting structure 2 and the main body 1.

[0080] Specifically, when the limiting structure 2 is slidably connected to the body 1 , an accommodating space 21 is formed between one end of the limiting structure 2 away from the accommodating channel 11 and the end of the body 1 , and an indefinite number of dumbbell plates can be placed in the accommodating space 21 .

[0081] It should be noted that the dumbbell plates are the component with the largest weight share in the adjustable dumbbell 100. It can be understood that when the limiting structure 2 slides in the accommodating channel 11 and relative to the main body 1, the size of the accommodating space 21 can also be adjusted accordingly. The specific adjustment method is as follows.

[0082] When the adjustable dumbbell 100 needs more dumbbell plates to increase the weight, the limiting structure 2 slides toward the side away from the main body 1. At this time, the accommodating space 21 can be expanded accordingly to increase the number of dumbbell plates. Conversely, when the adjustable dumbbell 100 needs to reduce the weight, the dumbbell plates with excess weight are removed, and the limiting structure 2 is pushed to slide toward the main body 1, thereby reducing the accommodating space 21 accordingly.

[0083] Furthermore, the locking assembly 3 provided on the adjustable dumbbell 100 remains movable during the process of adding or reducing dumbbell plates to the adjustable dumbbell 100. After the step of adjusting the dumbbell plates is completed, that is, after the weight adjustment of the adjustable dumbbell 100 is completed and before starting fitness, a part of the locking assembly 3 can movably pass through the main body 1 and cooperate with the limiting structure 2 located in the accommodating channel 11 to achieve locking between the two.

[0084] It should be noted that in the adjustable dumbbell 100 provided in the first embodiment of the utility model, the locking assembly 3 is movable when it is not matched with the limiting structure 2 located in the accommodating channel 11. At this time, the limiting structure 2 can slide relative to the main body 1, and then the dumbbell plates can be directly added, removed or replaced without disassembling the limiting structure 2, thereby realizing the weight adjustment of the dumbbell.

[0085] It should be further explained that the accommodating channel 11 connected to the outside is arranged inside the main body 1. Since the limiting structures 2 are respectively provided at both ends of the main body 1 and the dumbbell is symmetrical in structure, the number of the accommodating channels 11 can be one or two, which can be set according to actual needs.

[0086] Specifically, when the number of the accommodating channels 11 is one, the accommodating channel 11 opened inside the main body 1 needs to be set to be hollow, so that the two ends of the accommodating channel 11 are connected to the outside world, and then the limiting structures 2 located at the two ends of the main body 1 can be slidably connected with the main body 1 after passing through the accommodating channel 11; and when the number of the accommodating channels 11 is two, the accommodating channel 11 opened inside the main body 1 only needs to be set to have one end connected to the outside world, and a partition can be set between the two accommodating channels 11.

[0087] It can be understood that as a preferred implementation of the first embodiment of the utility model, the number of the accommodating channel 11 is one. The number of accommodating channels 11 is related to the size of the body 1 and the limiting structure 2. Therefore, the specific implementation of the first embodiment of the utility model is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the principles of the utility model should be included in the protection scope of the utility model.

[0088] The utility model designs a limiting structure 2 of an adjustable dumbbell 100 and a locking component 3 matched with the limiting structure 2, and the locking component 3 cooperates with the limiting structure 2 to achieve locking between the two, so that when the adjustable dumbbell 100 is used, it can avoid the situation that components such as the limiting structure 2 and dumbbell plates are separated or dropped. Through this design, the existing adjustable dumbbells need to install the dumbbell plates to the dumbbell rods through conventional adjustment methods and then lock the dumbbell plates through tightening nuts to achieve the weight adjustment of the dumbbells, and the technical problem that the operation of disassembling and replacing the dumbbell plates is very cumbersome is solved.

[0089] Please continue reading Figure 1 and Figure 2 The adjustable dumbbell 100 also includes a dumbbell plate assembly 4; the body 1 includes a grip 12 and fixed dumbbell plates 13 arranged at both ends of the grip 12, and the dumbbell plate assembly 4 is located in the accommodating space 21.

[0090] It can be understood that the main body 1 includes a grip 12 for the user of the adjustable dumbbell 100 to hold, and fixed dumbbell plates 13 arranged at both ends of the grip 12. By setting the fixed dumbbell plates 13, it is not necessary to spend much time and effort when adding, reducing or replacing dumbbell plates.

[0091] It should be noted that when the dumbbell plate assembly 4 is located in the accommodating space 21, the dumbbell plate assembly 4 is specifically arranged between the fixed dumbbell plate 13 and the limiting structure 2. After passing through the dumbbell plate assembly 4 and the fixed dumbbell plate 13, the limiting structure 2 enters the accommodating channel 11 and is slidably connected to the main body 1.

[0092] In addition, if fixed dumbbell plates 13 are not provided at both ends of the grip 12, when a dumbbell plate is installed on either side of the grip 12 and not installed on the other side, the grip 12 will form an inclined angle with the bottom surface, so it is more troublesome to install the dumbbell plate on the end where the dumbbell plate is not installed. It can be seen that in the scheme of the first embodiment of the utility model, the fixed dumbbell plate 13 also plays a role in stably installing the dumbbell plate.

[0093] For further information, see Figure 2 and Figure 3 The locking assembly 3 includes a connected fixing member 31 and a movable structure 32. The fixing member 31 is detachably connected to the grip rod 12 and / or the fixed dumbbell plate 13. The movable structure 32 can rotate relative to the fixing member 31 so that the movable structure 32 passes through the grip rod 12 and abuts against the limiting structure 2.

[0094] It can be understood that the locking assembly 3 of the adjustable dumbbell 100 provided in the first embodiment of the utility model includes a fixing member 31 and a movable structure 32 connected to the fixing member 31, and the fixing member 31 can be connected to either the grip 12 or the fixed dumbbell plate 13, or can be connected to both at the same time.

[0095] This design can improve the fixing effect of the locking assembly 3 on the limiting structure 2, thereby preventing the locking assembly 3 from detaching and causing the dumbbell piece located between the fixed dumbbell piece 13 and the limiting structure 2 to separate from the body 1.

[0096] Specifically, when the fixing member 31 is connected to the grip 12, the locking assembly 3 is fixedly connected to the grip 12 through the fixing member 31, and the fixing member 31 may not be in contact with the fixed dumbbell plate 13; when the fixing member 31 is connected to the fixed dumbbell plate 13, or the fixing member 31 is connected to both the grip 12 and the fixed dumbbell plate 13, the fixing member 31 is in contact with both the grip 12 and the fixed dumbbell plate 13. The detachable connection mode of the fixing member 31 can be set according to the manufacturing process, and the above-mentioned beneficial effects can be achieved regardless of whether the fixing member 31 is connected to one of the grip 12 or the fixed dumbbell plate 13 alone, or to both.

[0097] It should be noted that the connection method between the fixing member 31 and the grip 12 and / or the fixed dumbbell plate 13 includes but is not limited to a threaded connection and a snap connection, which can be set specifically according to actual conditions. As a preferred implementation scheme of the first embodiment of the utility model, the specific connection method for the detachable connection between the fixing member 31 and the fixed dumbbell plate 13 is a threaded connection.

[0098] Furthermore, on the basis that the fixing member 31 is detachably connected and fixed to the main body 1, the movable structure 32 can rotate relative to the fixing member 31, and an opening 121 can be set on the handle 12, so that at least a part of the movable structure 32 can pass through the handle 12 through the opening 121 to abut against the limiting structure 2, so that the movable structure 32 and the limiting structure 2 are in a mutually abutting state to achieve locking between the two.

[0099] Please continue reading Figure 1 and Figure 2 The limiting structure 2 includes a limiting rod 22 and a limiting member 23, one end of the limiting rod 22 is connected to the limiting member 23, and the side of the limiting rod 22 away from the limiting member 23 is penetrated into the accommodating channel 11 and is slidably connected to the gripping rod 12; the limiting member 23 cooperates with the fixed dumbbell plate 13 to clamp the dumbbell plate assembly 4.

[0100] It should be noted that, in the limiting structure 2 of the first embodiment of the utility model, the sliding connection between the limiting structure 2 and the grip 12 is realized by the limiting rod 22, and the side of the limiting rod 22 away from the limiting member 23 is penetrated through the accommodating channel 11, and the limiting rod 22 is penetrated through the accommodating channel 11, and the limiting member 23 cooperates with the fixed dumbbell plates 13 at both ends of the grip 12 to clamp the dumbbell plate assembly 4, that is, the dumbbell plate assembly 4 is located between the limiting member 23 and the grip 12.

[0101] It can be understood that at least part of the limiting rod 22 is successively passed through the dumbbell plate assembly 4 and the fixed dumbbell plate 13, and finally passed through the accommodating channel 11, so as to achieve the mutual cooperation between the limiting rod 22 and the limiting member 23.

[0102] With this design, the limiting rod 22 can be locked with the movable structure 32 of the locking assembly 3 in the accommodating channel 11, and the limiting member 23 can cooperate with the fixed dumbbell plate 13 to clamp the dumbbell plate assembly 4 therebetween.

[0103] It should be further explained that the shape of the limiting rod 22 corresponds to the shape of the accommodating channel 11, and the end of the accommodating channel 11 connected to the outside can be inserted into the limiting rod 22, so that the limiting rod 22 can slide between the gripping rod 12 through the accommodating channel 11.

[0104] Specifically, in the first embodiment of the utility model, the accommodating channel 11 through which the limiting rod 22 passes has a circular entrance, and the internal space of the accommodating channel 11 extends inward from the circular entrance to form a sliding channel for the limiting rod 22 to slide. The structure of the limiting rod 22 is a cylindrical shape that fits the circular accommodating channel 11, wherein the circular cross-sectional area of ​​the limiting rod 22 facing the accommodating channel 11 is slightly smaller than the area of ​​the circular entrance. Through this design, the limiting rod 22 can slide relative to the gripping rod 12 in the accommodating channel 11.

[0105] See also Figures 3 to 5 A protrusion 324 is provided on the movable structure 32 , and the protrusion 324 abuts against the limiting rod 22 after passing through the handle 12 .

[0106] It can be understood that the locking assembly 3 of the first embodiment of the present invention includes a fixing member 31 and a movable structure 32 that can rotate relative to the fixing member 31 . In the movable structure 32 , the protrusion 324 passes through the gripping rod 12 and abuts against the limiting rod 22 .

[0107] Furthermore, the limiting rod 22 is a threaded rod, and the protrusion 324 is provided with a matching thread 3241 that adapts to the limiting rod 22. The protrusion 324 is threadedly matched with the limiting rod 22 after passing through the handle bar 12, or the limiting rod 22 is provided with a fixing groove 221 corresponding to the protrusion 324, and the protrusion 324 is engaged and connected with the fixing groove 221 after passing through the handle bar 12.

[0108] Specifically, when the abutment between the two is threaded cooperation, the limit rod 22 is a threaded rod, and the protrusion 324 is provided with a matching thread 3241, which is adapted to the limit rod 22 as a threaded rod, so that the protrusion 324 is threadedly locked with the limit rod 22 after passing through the grip rod 12.

[0109] When the abutment between the two is a snap-fit ​​connection, it is sufficient for the protrusion 324 to have a protrusion, and a fixing groove 221 is provided on the limiting rod 22 . The size of the fixing groove 221 corresponds to the size of the protrusion 324 , and the fixing groove 221 is specifically provided on the outer peripheral surface of the limiting rod 22 .

[0110] It should be noted that in the specific implementation of the first embodiment of the utility model, the abutment between the protrusion 324 and the limit rod 22 can be a threaded fit, a snap-fit ​​connection, or other abutment methods. That is to say, the specific implementation of this embodiment cannot be used to limit the utility model. Any modifications, equivalent replacements and improvements made within the principles of the utility model should be included in the protection scope of the utility model.

[0111] Please continue reading Figure 3 and Figure 4 The movable structure 32 includes a main movable member 321, a secondary movable member 322 and a locking member 323 which are arranged in sequence, and two ends of the secondary movable member 322 are rotatably connected to the main movable member 321 and the locking member 323 respectively.

[0112] It can be understood that in the first embodiment of the utility model, the movable structure 32 is composed of a main movable part 321, a secondary movable part 322 and a locking part 323 which are connected in sequence. The main movable part 321 is rotatably connected to the secondary movable part 322, and the locking part 323 is also rotatably connected to the secondary movable part 322.

[0113] Furthermore, the main movable member 321 is rotatably connected to the fixed member 31 at one end thereof away from the auxiliary movable member 322 .

[0114] It should be noted that, in the locking assembly 3, the fixing member 31 is connected to the movable structure 32 in the following manner: the fixing member 31 is first rotationally connected to one end of the main movable member 321, and the other end of the main movable member 321 is then rotationally connected to the auxiliary movable member 322, and the locking member 323 is also rotationally connected to the auxiliary movable member 322, wherein the positions where the main movable member 321 and the locking member 323 are rotationally connected to the auxiliary movable member 322 are respectively located on both sides of the auxiliary movable member 322.

[0115] In the first embodiment of the utility model, since the fixing member 31 is detachably connected to the fixed dumbbell plate 13 and is rotatably connected to the main movable member 321, combined with the rotation relationship of the remaining components in the movable structure 32, it can be seen that the fixing member 31 and the movable structure 32 in the locking assembly 3 can together form a hollow circular object.

[0116] Furthermore, the protrusion 324 is arranged on the side of the main movable part 321 facing the fixed part 31. When the protrusion 324 is not abutted against the limit rod 22, the two ends of the auxiliary movable part 322 can respectively rotate with the main movable part 321 and the locking part 323; and when the protrusion 324 is abutted against the limit rod 22, the locking part 323 rotates relative to the auxiliary movable part 322 to a locked state.

[0117] It should be noted that the fixed part 31 is rotatably connected to the main movable part 321 at the end away from the auxiliary movable part 322. By setting the connection between the fixed part 31 and the grip 12 and / or the fixed dumbbell plate 13 to be a detachable connection, it is possible to prevent components in the movable structure 32 from falling, being damaged or lost when the protrusion 324 is not abutted against the limit rod 22.

[0118] For further information, see Figure 6 The dumbbell plate assembly 4 includes a first dumbbell plate 41 and a second dumbbell plate 42 . The first dumbbell plate 41 is arranged between the fixed dumbbell plate 13 and the second dumbbell plate 42 . The weight of the first dumbbell plate 41 is greater than the weight of the second dumbbell plate 42 .

[0119] It can be understood that the dumbbell plate assembly 4 provided in the first embodiment of the present invention includes a first dumbbell plate 41 and a second dumbbell plate 42 , and the difference between the two includes the difference in weight, wherein the weight of the first dumbbell plate 41 is greater than the weight of the second dumbbell plate 42 .

[0120] Generally speaking, the strength of each dumbbell user is different due to factors such as age and gender. If the weight of each dumbbell plate is the same, it is impossible to find a dumbbell weight suitable for each person by fine-tuning the weight. Therefore, the first embodiment of the utility model solves this technical problem by providing dumbbell plates of different weights.

[0121] It should be noted that in the actual application of existing adjustable dumbbells, the dumbbell pieces close to the grip are generally heavier than the dumbbell pieces far from the grip, while the weight of the dumbbell pieces far from the grip is less than or equal to the weight of the dumbbell pieces close to the grip. If the placement is opposite to the above, the actual weight of the dumbbells picked up during fitness will be heavier. The specific reason is that the force point has changed, which will not be elaborated here.

[0122] As an alternative implementation, see Figure 3 , Figure 6 and Figure 7 A mounting opening 411 and a mounting groove 412 connected to the mounting opening 411 are provided at the bottom of the first dumbbell piece 41 and the second dumbbell piece 42. The mounting groove 412 extends to the middle of the first dumbbell piece 41 and the second dumbbell piece 42. The width of the mounting groove 412 is greater than the diameter of the limiting rod 22.

[0123] It can be understood that a mounting port 411 and a mounting groove 412 are provided on the first dumbbell plate 41 and the second dumbbell plate 42, wherein the mounting port 411 is arranged at the bottom of the first dumbbell plate 41 and the second dumbbell plate 42, and the mounting groove 412 is connected to the mounting port 411 and extends to the middle of the first dumbbell plate 41 and the second dumbbell plate 42.

[0124] Further, please continue to combine Figure 2 The width of the mounting groove 412 is set to be larger than the diameter of the limiting rod 22. Through this design, the first dumbbell piece 41 and / or the second dumbbell piece 42 can be placed on the limiting rod 22 through the mounting groove 412 when the limiting rod 22 is inserted into the accommodating channel 11 and is slidably connected to the gripping rod 12. The dumbbell pieces can be added, reduced or replaced by only pulling the limiting member 23 to make the limiting rod 22 slide a certain distance toward the side away from the main body 1.

[0125] It should be noted that the first embodiment of the utility model provides a mounting port 411 and a mounting groove 412 connected to the mounting port 411 at the bottom of the dumbbell plate, which makes it more convenient and quick to add or reduce the first dumbbell plate 41 and the second dumbbell plate 42 or replace different dumbbell plates, thereby saving the time and effort spent on disassembly and assembly.

[0126] See also Figure 7 and Figure 8Between adjacent fixed dumbbell plates 13 and the first dumbbell plates 41 or the second dumbbell plates 42, between adjacent first dumbbell plates 41, between adjacent first dumbbell plates 41 and the second dumbbell plates 42, and between adjacent second dumbbell plates 42, one is provided with a positioning structure 413, and the other is provided with a positioning groove 414 that cooperates with the positioning structure 413.

[0127] It should be noted that, by providing a positioning structure 413 and a positioning groove 414 that cooperates with the positioning structure 413 between the dumbbell plates, when the first dumbbell plate 41 and / or the second dumbbell plate 42 are placed between the limiting member 23 and the fixed dumbbell plate 13, the positioning structure 413 on one of the dumbbell plates will be inserted into the positioning groove 414 on the adjacent dumbbell plate, thereby realizing the axial positioning of the dumbbell plates, so that the dumbbell plates will not move relative to each other, thereby preventing misalignment of the dumbbell plates, and having higher safety and stability.

[0128] It can be understood that the positioning structure 413 and the positioning groove 414 that cooperates with the positioning structure 413, a single positioning structure 413 and a positioning groove 414 are a pair of positioning components, which are respectively arranged between adjacent dumbbell plates, wherein a dumbbell plate includes at least one positioning structure 413 or a positioning groove 414. If the dumbbell plate is provided with a positioning structure 413, then the corresponding technical problems mentioned above can be solved by providing corresponding matching positioning grooves 414 on adjacent dumbbell plates.

[0129] In particular, if a positioning structure 413 is provided on a dumbbell plate, at least a positioning groove 414 is provided on the adjacent dumbbell plate, and the positioning groove 414 is provided at a corresponding position of the adjacent dumbbell plate facing the positioning structure 413 .

[0130] Optionally, the first dumbbell piece 41 and the second dumbbell piece 42 are set adjacent to each other, and on the first dumbbell piece 41 and the second dumbbell piece 42, one is provided with a positioning structure 413, and the other is provided with a positioning groove 414, wherein the positions of the positioning structure 413 and the positioning groove 414 can be interchanged with each other, and the corresponding technical effects can also be achieved, which is equivalent to making an equivalent replacement for the first embodiment of the utility model. Therefore, any modifications, equivalent replacements and improvements made within the principles of the utility model should be included in the protection scope of the utility model.

[0131] As another alternative implementation, see Figure 6 and Figure 7 A lifting structure 415 and / or a weight-reducing hole 416 are provided on the fixed dumbbell plate 13, the first dumbbell plate 41 and / or the second dumbbell plate 42.

[0132] It can be understood that by providing a lifting structure 415 on the fixed dumbbell plate 13, the first dumbbell plate 41 and / or the second dumbbell plate 42, it is possible to save effort when adding, removing or replacing dumbbell plates and avoid potential safety hazards that may be caused by directly taking the dumbbell plates; and by providing a weight-reducing hole 416 on the dumbbell plates, it is possible to reduce costs accordingly and achieve lightweighting of the adjustable dumbbells while meeting the weight requirements of the dumbbell plates.

[0133] As an implementation scheme of the first embodiment of the utility model, a lifting structure 415 and a weight-reducing hole 416 are provided on the fixed dumbbell plate 13 , the first dumbbell plate 41 and the second dumbbell plate 42 .

[0134] It should be noted that the lifting structure 415 can be a lifting rod set near the top of the dumbbell plate, or a hollow lifting hole can be opened on the dumbbell plate; for the adjustable dumbbell of the utility model, the lifting structure 415 is preferably a lifting hole, which can avoid the lifting rod affecting the use of the adjustable dumbbell during fitness.

[0137] It can be understood that the adjustable dumbbell provided in the first embodiment of the utility model can conveniently adjust the weight of the dumbbell, and the operation is very simple. Through the sliding connection between the limiting structure and the main body, a accommodating space for placing dumbbell plates is formed between the end of the limiting structure away from the accommodating channel and the end of the main body. The weight of the dumbbell plates can be configured in the accommodating space, for example, the number of dumbbell plates can be increased or decreased, and heavier or lighter dumbbell plates can be replaced.

[0138] Furthermore, the locking assembly on the adjustable dumbbell can be completed during the step of adjusting the dumbbell plates, that is, after the weight of the adjustable dumbbell is adjusted and before starting fitness, a part of the locking assembly can movably pass through the body and cooperate with the limiting structure located in the accommodating channel to achieve locking between the two.

[0139] It should be noted that the utility model designs a limiting structure of an adjustable dumbbell and a locking component that cooperates with the limiting structure, and the locking component cooperates with the limiting structure to achieve locking between the two, so that when using the adjustable dumbbell, it can avoid the situation where components such as the limiting structure and dumbbell plates are detached or dropped. Through this design, it solves the technical problem that the existing adjustable dumbbells need to install the dumbbell plates to the dumbbell rod through the conventional adjustment method and then lock the dumbbell plates through the tightening nut to achieve the weight adjustment of the dumbbell, and the operation of disassembling and replacing the dumbbell plates is very cumbersome.

[0153] It should be noted that the fixed part is rotatably connected to the main movable part at the end away from the auxiliary movable part. By setting the connection between the fixed part and the grip bar and / or the fixed dumbbell plate to be a detachable connection, it is possible to prevent parts in the movable structure from falling, being damaged or lost when the protrusion is not abutted against the limit rod.
