Description

A dumbbell device Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a dumbbell device. Background Technology

[0002] As people's living standards continue to improve, their pursuit of material things is getting higher and higher, especially in terms of demand for fitness equipment. Dumbbells, as a fitness tool that can be used to exercise the body, have attracted much attention from consumers.

[0003] When using dumbbell devices, users sometimes attach multiple weight plates to one end of the main body. To overcome the safety issue caused by the inability to remove the weight plates in sequence, some dumbbell devices use interlocking mechanisms between the weight plates and between the weight plates and the main body, along with a telescopic rod inside the main body, to stop the movement. This ensures that the weight plates at one end of the main body can only be removed sequentially from the direction away from the main body towards the direction closer to the main body. Moreover, to improve the safety of removal, sometimes a base is required to remove the weight plates (such as Chinese patent with publication number CN218740044U), which is very inconvenient for users. Summary of the Invention

[0004] The technical problem solved by this utility model is to provide a dumbbell device that is easy to assemble and disassemble and has high safety in use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dumbbell device, comprising:

[0006] The main body is provided with a socket;

[0007] The counterweight comprises a plurality of bell blades arranged sequentially, with adjacent bell blades being rotatable relative to each other for detachable connection. The innermost bell blade is rotatable relative to the main body for detachable connection. Each bell blade includes a main body having a first surface, a second surface, and a through hole connecting the first surface and the second surface. The first surface also has a socket. A pin is slidably provided at the through hole, and the length of the pin is greater than the depth of the through hole. In two adjacent bell blades, the second surface of the outer bell blade abuts against the pin of the inner bell blade, so that the pin is inserted into its corresponding socket.

[0008] In one embodiment, the bell further includes a reset member that contacts the pin and the body to drive one end of the pin near the body back into the through hole.

[0009] In one embodiment, the reset member is sleeved on the pin, the pin having an outward protrusion, and the reset member contacts the outward protrusion.

[0010] In one embodiment, the reset element is a spring, a spring pad, or a rubber block.

[0011] In one embodiment, both the first surface and the second surface are planar, and the first surface and the second surface are disposed opposite to each other. The sliding direction of the pin is perpendicular to the first surface.

[0012] In one embodiment, the end face of the body and one side of the bell are respectively provided with grooves, and the other side of the bell is provided with a protrusion adapted to the groove. The protrusion is provided with a locking structure, and the groove is provided with a mating structure that cooperates with the locking structure.

[0013] In one embodiment, the first surface is the bottom surface of the groove on the bell, and the second surface is the end surface of the protrusion.

[0014] In one embodiment, the locking structure includes at least one of a threaded structure and a snap-fit ​​structure.

[0015] In one embodiment, the pins in two adjacent bell blades are misaligned.

[0016] In one embodiment, among two adjacent bells, the second surface of the outer bell may or may not be in contact with the first surface of the inner bell.

[0017] The beneficial effects of this utility model are as follows: This dumbbell device has a simple structure, low manufacturing cost, and high stability. For two adjacent weight plates, since the outer weight plate drives the pin in the inner weight plate to insert into the socket, the inner weight plate cannot rotate and unlock due to the pin restriction if the outer weight plate is not removed. Therefore, the inner weight plate cannot be removed synchronously with the outer weight plate. In other words, the weight plates in the counterweight can only be removed sequentially, which effectively improves the safety of the dumbbell device. Moreover, the weight plates are installed and removed by rotation, so users can operate with one hand without the aid of other parts. The user's operation of removing the weight plates is also very simple, which enhances the user experience. Attached Figure Description

[0036] Example 1

[0037] Please refer to Figures 1 to 4. Embodiment 1 of this utility model is as follows: Referring to Figures 1 to 3, a dumbbell device includes a body 1 and a counterweight. The body 1 has a socket 3. The counterweight includes a plurality of bell plates 2 arranged sequentially. Adjacent bell plates 2 can rotate relative to each other to achieve a detachable connection. The innermost bell plate 2 can rotate relative to the body 1 to achieve a detachable connection. The bell plate 2 includes a body 21, which has a first surface 22, a second surface 23, and a through hole 24 connecting the first surface 22 and the second surface 23. The through hole 24 is offset from the central axis of the bell plate 2. The first surface 22 also has the socket 3. A pin 4 is slidably provided at the through hole 24, and the length of the pin 4 is greater than the depth of the through hole 24.

[0038] In two adjacent bells 2, the second surface 23 of the outer bell 2 abuts against the pin 4 on the inner bell 2, so that the pin 4 is inserted into its corresponding socket 3. Specifically, as shown in Figures 2 and 3, when there are two bells 2, one end of the pin 4 on the inner bell 2 is inserted into the socket 3 on the body 1 under the drive of the outer bell 2; as shown in Figure 4, when there are three bells 2, one end of the pin 4 on the innermost bell 2 is inserted into the socket 3 on the body 1 under the drive of the middle bell 2, and one end of the pin 4 on the middle bell 2 is inserted into the socket 3 on the innermost bell 2 under the drive of the outermost bell 2; when there are more than three bells 2, the state when there are three bells 2 can be referred to, and will not be repeated here.

[0039] In one or more embodiments, the movement of the pin 4 can be driven by its own gravity. For example, when removing the first end of the dumbbell device, the first end can be turned downwards. At this time, the pin 4 on the outer side of the dumbbell 2 will disengage from the corresponding insertion hole 3 under its own gravity. To further improve the user experience, as shown in Figures 2 and 3, the dumbbell 2 preferably also includes a reset member 5. The reset member 5 contacts the pin 4 and the body 21 to drive the end of the pin 4 near the body 1 back into the through hole 24.

[0040] In some embodiments, the reset member 5 is sleeved on the pin 4, the pin 4 having an outward protrusion 41, and the reset member 5 contacts the outward protrusion 41. Optionally, the main body 21 is further provided with a receiving groove 25 for accommodating the reset member 5. The reset member 5 is a spring, a spring pad, a rubber block, or other structural component with a rebound capability.

[0041] In this embodiment, both the first surface 22 and the second surface 23 are planar, and the first surface 22 and the second surface 23 are arranged opposite to each other, with the sliding direction of the pin 4 perpendicular to the first surface 22. Specifically, the end face of the body 1 and one side of the bell 2 are respectively provided with grooves 6. The first surface 22 is the bottom surface of the groove 6 on the bell 2, and the other side of the bell 2 is provided with a protrusion 26 adapted to the groove 6. The second surface 23 is the end face of the protrusion 26. More specifically, the protrusion 26 on the innermost bell 2 engages with the groove 6 on the body 1; among two adjacent bell 2, the protrusion 26 on the outer bell 2 engages with the groove 6 on the inner bell 2.

[0042] The protrusion 26 is provided with a locking structure 261, and the groove 6 is provided with a mating structure 61 that mates with the locking structure 261. The protrusion 26 is a circular boss, and the locking structure 261 is provided on the outer peripheral wall of the protrusion 26. The locking structure 261 includes at least one of a threaded structure and a snap-fit ​​structure.

[0043] The pins 4 in two adjacent bell blades 2 are staggered, that is, the counterweight includes at least two bell blades 2 with slightly different structures, specifically in the different positions of the through holes 24 and the insertion holes 3 on the bell blades 2 (see Figure 4).

[0044] In two adjacent bells 2, the second surface 23 of the outer bell 2 may or may not be in contact with the first surface 22 of the inner bell 2.

[0045] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
