[0035] Reference Figure 1-6 As shown, a smart dumbbell with quick-release bell pieces includes a dumbbell body 100 and a bell piece assembly 200 detachably connected to the dumbbell body 100;

[0036] The dumbbell body 100 is provided with a clamping groove 300 at both ends, and the dumbbell plate assembly 200 is provided with a clamping boss 400 at one side;

[0037] The side walls of the clamping groove 300 and the clamping boss 400 are provided with screw thread claws 500;

[0038] The side wall of the clamping groove 300 or the clamping boss 400 is provided with an elastic member, and the side wall of the clamping boss 400 or the clamping groove 300 is provided with a limiting groove 700 corresponding to the elastic member;

[0039] When the engaging groove 300 and the engaging boss 400 are screwed together through the screw claws 500 , the elastic member is engaged with the limiting groove 700 to fix the bell plate assembly 200 .

[0040] By adopting a rotating snap-fit ​​structure and the snap-fitting of the elastic member with the limiting groove 700, the utility model realizes the rapid assembly and disassembly of the dumbbells. This design simplifies the cumbersome steps in the traditional dumbbell assembly and disassembly process, improves the convenience of the user, and allows the user to quickly adjust the dumbbell weight according to the exercise needs in a short time. The elastic member is located in the limiting groove 700 and is used to fix the dumbbell assembly 200. This structural design can effectively prevent the dumbbell from accidentally falling off during exercise, thereby ensuring the safety of the user. At the same time, the design of the snap-fit ​​boss 400 and the snap-fit ​​groove 300 also enhances the stability of the structure and reduces the risk of failure during high-intensity exercise. The utility model reduces the use of additional hardware by simplifying the structural design, thereby reducing the production cost. At the same time, through reasonable design, the overall structural strength of the dumbbell is ensured, and the problem of strength reduction caused by complex structure is avoided.

[0041] And by hiding the elastic member in the side wall of the clamping groove 300 or the clamping boss 400, scratches on the surface due to contact and friction between the bell pieces in daily use can be avoided. In this way, the appearance design of the bell piece assembly 200 can be kept novel for a long time, improving the aesthetics and overall visual effect of the product. The elastic member is a key component in the bell piece quick-release structure. If it is located on the surface of the bell piece, it is more susceptible to wear and damage. Designing it inside can provide it with better protection, thereby extending the service life of the entire bell piece assembly 200. Since the elastic member is not easily affected by external factors, the frequency of maintenance and replacement is reduced, and the user's maintenance cost and use cost are reduced. There is no exposed elastic member, which makes it easier to clean the bell piece. Users do not need to worry about detergent or moisture entering the elastic member, thereby avoiding corrosion or other damage that may be caused by it.

[0042] In this embodiment, the inner wall of the clamping groove 300 and the outer wall of the clamping boss 400 are provided with screw claws 500, and the clamping groove 300 is screwed with the clamping boss 400. The inner wall of the clamping groove 300 and the outer wall of the clamping boss 400 are both designed with screw claws 500. These claws correspond to each other and can bite each other during the screw connection process. When the user installs the bell piece assembly 200, the clamping boss 400 is inserted into the clamping groove 300, and then rotates it so that the inner and outer screw claws 500 bite each other to form a stable mechanical connection. Through the positive and negative directions of the rotation action, the user can easily fix or remove the bell piece assembly 200. Clockwise rotation is used for connection, and counterclockwise rotation is used for removal.

[0043] The threaded connection mechanism makes the installation and removal of the dumbbell assembly 200 simple and quick, and the user can quickly adjust the dumbbell weight according to the exercise requirements. The outer wall of the clamping boss 400 is designed with a telescopic steel ball 610, and the inner wall of the clamping groove 300 is designed with a corresponding limiting groove 700. When the bell assembly 200 is rotated into place, the elastic member is clamped with the limiting groove 700, thereby locking the bell assembly 200 to ensure that it will not accidentally fall off during exercise.

[0044] Reference Figure 1-3 As shown in the first embodiment, the elastic member is a telescopic steel ball 610, and the telescopic steel ball 610 penetrates the side wall of the clamping groove 300 or the clamping boss 400. A spring is provided between the telescopic steel ball 610 and the clamping groove 300 or the clamping boss 400.

[0045] The combination of the telescopic steel ball 610 and the spring can provide a strong fixing force to ensure that the bell assembly 200 is firmly fixed during use. The telescopic steel ball 610 penetrates the side wall of the clamping groove 300 or the clamping boss 400, and the spring maintains the telescopic steel ball 610 extending out of the side wall, forming a reliable fixing mechanism, which increases the stability of the bell assembly 200. When the bell needs to be loaded and unloaded, the user inserts the clamping boss 400 of the bell assembly 200 into the clamping groove 300, and the telescopic steel ball 610 will be squeezed into the side wall of the clamping boss 400 or the clamping groove 300. A spring is provided between the telescopic steel ball 610 and the clamping groove 300 or the clamping boss 400, and the function of the spring is to maintain the telescopic steel ball 610 extending out of the side wall of the clamping groove 300 or the clamping boss 400. When the bell assembly 200 is rotated into position, the telescopic steel ball 610 will rebound through the action of the spring and engage with the limiting groove 700, ensuring that the bell assembly 200 will not loosen or fall off during use.

[0046] In implementation case 1, the clamping boss 400 is provided with a telescopic steel ball 610, and the side wall of the clamping groove 300 is provided with a limiting groove 700 corresponding to the telescopic steel ball 610, and the telescopic steel ball 610 is located in the limiting groove 700 for fixing the bell plate assembly 200.

[0047] The clamping boss 400 is screwed into the clamping groove 300, and the telescopic steel ball 610 is squeezed into the limiting groove 700. The telescopic steel ball 610 and the limiting groove 700 are clamped and fixed to the bell piece assembly 200. When the clamping boss 400 is screwed into place, the limiting groove 700 is aligned with the telescopic steel ball 610, and the telescopic steel ball 610 is clamped with the limiting groove 700. The bell piece assembly 200 is fixed by the elastic force of the telescopic steel ball 610 to prevent the bell piece assembly 200 from accidentally falling off during use. When the bell piece assembly 200 needs to be disassembled, it is rotated vigorously along the tangential direction of the bell piece assembly 200 to squeeze the telescopic steel ball 610 to retract it without affecting the disassembly of the bell piece assembly 200.

[0048] In the first embodiment, the bell assembly 200 includes a bell housing 220, a bell weight block 230 and a bell end cover 240;

[0049] The bell housing 220 is fixedly connected to the bell end cover 240, and a cavity is formed between the bell housing 220 and the bell end cover 240, and the bell counterweight 230 is fixed in the cavity. The closed design of the bell assembly 200 makes the appearance more neat and beautiful, and improves the overall aesthetic value of the product. The bell housing 220 and the bell end cover 240 are manufactured by injection molding. Injection molding is an efficient manufacturing method that can form complex shapes and structures in one go, and is suitable for large-scale production.

[0050] Reference Figure 7As shown, in the implementation case, a battery cavity is provided in the dumbbell body 100, and the opening of the battery cavity is located at the bottom of the snap-in groove 300, and a detachably connected battery compartment 900 is provided in the battery cavity. A special battery cavity is designed inside the dumbbell body 100, and this space is specially reserved for installing batteries or other power supply devices. The battery cavity is designed inside the dumbbell body 100, which keeps the appearance of the dumbbell neat and beautiful, without additional protrusions or external connecting wires. The bell plate assembly 200 covers the opening of the battery cavity, maintaining the integrity of the dumbbell appearance, making the product more visually beautiful. This design is both practical and beautiful, which enhances the attractiveness of the product.

[0051] Reference Figure 4-6 As shown in the second embodiment, the elastic member is an elastic pick 620, and a limiting protrusion is provided on the surface of the elastic pick 620. Compared with the telescopic steel ball 610, the elastic pick 620 is easier to install, thereby improving production efficiency. Once the bell assembly 200 is rotated into place, the elastic pick 620 will rebound through its elastic force, and the limiting protrusion is located in the limiting groove 700, thereby fixing the bell assembly 200.

[0052] In the second implementation example, the elastic paddle 620 is fixed to the bottom end of the clamping groove 300 by a clamping member 621, and the elastic paddle 620 is integrated with the clamping member 621;

[0053] The side wall of the clamping groove 300 is provided with a notch 622 for the elastic paddle 620 to pass through, and the clamping boss 400 is provided with a limiting groove 700 corresponding to the limiting protrusion.

[0054] When the bell piece needs to be installed, the user inserts the engaging boss 400 of the bell piece assembly 200 into the engaging groove 300, and the elastic pick 620 is squeezed and enters the engaging groove 300 through the notch 622. Once the bell piece assembly 200 is rotated into place, the elastic pick 620 rebounds by its elastic force and engages with the bottom end of the engaging groove 300, and the limiting protrusion corresponds to the limiting groove 700, fixing the bell piece assembly 200.

[0055] By using the elastic pick 620 as the elastic member, the structural design of the bell assembly 200 is simplified, the number and complexity of parts are reduced, and the production cost is reduced.

[0056] Reference Figure 1-2 As shown, in the embodiment further, one side of the bell piece assembly is provided with a snap-in groove, and the other side is provided with a snap-in groove;

[0057] The bell plate assembly is used for detachable connection by cooperating with other bell plate assemblies or the clamping grooves of the dumbbell body through the clamping boss. Through the cooperation of the clamping boss and the clamping groove, the bell plate assembly can be quickly and easily disassembled and connected. The user only needs to insert the clamping boss into the clamping groove to complete the connection of the bell plate assembly. Conversely, the user only needs to pull out the clamping boss to disassemble the bell plate assembly. The bell plate assembly is detachably connected by cooperating with the clamping boss and the clamping groove. This means that the user can freely combine the bell plate assemblies according to needs and flexibly adjust the weight and training intensity. The clamping design of the bell plate assembly allows it to be connected with other bell plate assemblies or the dumbbell body, providing greater flexibility and diversity to meet different training needs.

[0058] Reference Figure 2-3 As shown, in the embodiment, the side of the bell assembly 200 is provided with an identification portion 800, and the direction of the identification portion 800 corresponds to the direction of the limit steel ball to distinguish the direction of the bell assembly 200. The side of the bell assembly 200 is specially designed with an identification portion 800, and this identification portion 800 can be a logo, symbol, text or color distinction, etc., used to indicate the correct direction of the bell assembly 200. The direction of the identification portion 800 corresponds to the installation direction of the limit steel ball inside the bell assembly 200. The limit steel ball is used to ensure that the bell assembly 200 is correctly aligned and fixed during the screwing process. When the bell assembly 200 is correctly screwed into place, the identification portion 800 will be in a preset direction, such as upward, so that the user can intuitively see the identification portion 800 and confirm that the bell assembly 200 has been correctly installed. If the bell assembly 200 is not screwed into place, the direction of the identification portion 800 will be displayed incorrectly, and the user can quickly find and adjust it to avoid the risk of use caused by improper installation.

[0059] The design of the marking portion 800 allows the user to intuitively determine whether the bell plate assembly 200 is installed in place, thereby reducing the risk of accidents caused by improper installation. Through the indication of the marking portion 800, the user can easily confirm the installation status of the bell plate assembly 200 without complicated inspection or guesswork, making the use process more convenient and quick. For beginners or gym trainers, the marking portion 800 provides a clear reference point to facilitate teaching and learning the correct installation method.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
