Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a disassembly and assembly structure for dumbbell plates. Background Technology

[0002] Dumbbells are auxiliary equipment used in weightlifting and fitness exercises. Smaller than barbells, they come in a variety of weights and sizes to suit different people and exercise needs, making them popular among fitness enthusiasts. Common dumbbells on the market generally consist of a central handle and fixed or detachable weight plates on either side of the handle, and are typically made of cast iron coated with rubber or similar materials.

[0003] Most existing dumbbell plates are screwed onto the dumbbell bar by the engagement of the threads on their inner wall with the threads on the dumbbell bar. However, installing and removing dumbbell plates requires screwing them onto or off the dumbbell bar one turn at a time, which is cumbersome and reduces efficiency. Furthermore, the round shape of the dumbbell plates makes the dumbbell prone to rolling when placed on the ground. To address this technical problem, this application proposes a dumbbell plate assembly and disassembly structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dumbbell plate assembly / disassembly structure. This structure involves inserting a small dumbbell plate into a slot on a large dumbbell plate, and using a spring to push a movable block into the slot of the insert, thus securing the dumbbell plate firmly and preventing it from wobbling. Furthermore, by screwing the limiting sleeve onto the dumbbell bar, the structure further ensures the dumbbell plate won't fall off, allowing users to focus more intently and safely on their workouts. The movable block also provides some resistance to the dumbbells, preventing them from rolling around and making storage and placement of the dumbbells more organized and efficient. This positively impacts the cleanliness of the workout environment and the convenience of daily use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dumbbell plate assembly / disassembly structure includes a dumbbell bar with a large dumbbell plate and a small dumbbell plate fitted at its left and right ends. The outer wall of the large dumbbell plate has two moving grooves, and a moving block is disposed in each moving groove. Limiting blocks are fixedly connected to the middle of both sides of the moving block. Two slots are provided on the side of the dumbbell bar near the small dumbbell plate, and two inserts are fixedly connected to the side of the small dumbbell plate near the dumbbell bar.

[0007] Furthermore, mounting holes are provided at the middle of the large dumbbell plate and the small dumbbell plate.

[0008] Furthermore, the outer walls of both ends of the dumbbell bar are threaded.

[0009] Furthermore, a slot is provided at the top of the insert block, the slot passes through the insert block, and the size of the slot is adapted to the size of the moving block.

[0010] Furthermore, the slot communicates with the movable slot.

[0011] Furthermore, two springs are provided in the moving slot, one end of the spring is connected to the large dumbbell plate, and the other end of the spring is connected to the moving block.

[0012] Furthermore, the inner walls on both sides of the movable groove are provided with limiting grooves that are adapted to the limiting block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by inserting the small dumbbell plate into the slot of the large dumbbell plate, and using a spring to push the moving block into the slot of the insert, the dumbbell plate can be firmly fixed and prevented from shaking. At the same time, by screwing the limiting sleeve onto the dumbbell bar, the dumbbell plate can be further guaranteed not to fall off, allowing the user to focus more and exercise more safely.

[0015] 2. In this utility model, by utilizing the movable block, the dumbbells can be blocked to a certain extent, thereby preventing the dumbbells from rolling around randomly, making the storage and placement of dumbbells more orderly and tidy, which has a positive impact on the maintenance of the exercise environment and the convenience of daily use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-3 This utility model provides an embodiment of a dumbbell plate assembly / disassembly structure, including a dumbbell bar 1, with a large dumbbell plate 2 and a small dumbbell plate 3 fitted at both ends of the dumbbell bar 1. Two movable grooves 4 are formed on the outer wall of the large dumbbell plate 2, and movable blocks 5 are provided within the movable grooves 4. The movable blocks 5 can move within the movable grooves 4. Limiting blocks 11 are fixedly connected to the middle of both sides of the movable blocks 5. The limiting blocks 11 ensure the stability of the movable blocks 5 within the movable grooves 4. Two slots 9 are formed on the side of the dumbbell bar 1 near the small dumbbell plate 3. The size of the slots 9 is adapted to the size of the insert blocks 7. Two insert blocks 7 are fixedly connected to the side of the small dumbbell plate 3 near the dumbbell bar 1. By inserting the insert blocks 7 into the slots 9, the small dumbbell plate 3 can be connected to the large dumbbell plate 2.

[0023] Reference Figure 1-3 The dumbbell plate 2 and the small dumbbell plate 3 each have a mounting hole 6 at their middle ends. The outer walls of both ends of the dumbbell bar 1 are threaded, and limit sleeves are provided at both ends of the dumbbell bar 1, with threaded inner walls on the limit sleeves as well. A slot 8 is provided at the top of the insertion block 7, passing through the insertion block 7. The size of the slot 8 is adapted to the size of the moving block 5, allowing the insertion block 7 to be limited by inserting the moving block 5 into the slot 8. The slot 9 communicates with the moving slot 4. Two springs 10 are provided inside the moving slot 4. One end of each spring 10 is connected to the large dumbbell plate 2, and the other end is connected to the moving block 5. The springs 10 allow the moving block 5 to reset, thus automatically inserting it into the slot 8. Limiting grooves adapted to the limit blocks 11 are provided on the inner walls of both sides of the moving slot 4.

[0024] Working principle: First, place the dumbbell bar 1 on the dumbbell rack. Then, slip the large dumbbell plate 2 and the small dumbbell plate 3 onto the end of the dumbbell bar 1. Next, move the moving block 5 to compress the spring 10. Then, insert the insert 7 on the side of the small dumbbell plate 3 closest to the large dumbbell plate 2 into the slot 9 on the side of the large dumbbell plate 2 closest to the small dumbbell plate 3. Then, release the moving block 5, so that the spring 10 pushes the moving block 5 into the slot 8 on the insert 7, thereby limiting the movement of the small dumbbell plate 3 and the large dumbbell plate 2 and preventing them from shaking during dumbbell use. Finally, screw the limiting sleeve onto the end of the dumbbell bar 1 to prevent the large dumbbell plate 2 and the small dumbbell plate 3 from falling off the dumbbell bar 1. The moving block 5 also prevents the dumbbell from rolling when it is placed on the ground.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
