Description

Technical Field

[0001] The utility model relates to the technical field of dumbbell equipment, in particular to a novel dumbbell. Background Art

[0002] Traditional dumbbell designs often rely on a set of clamping and fixing structures to achieve the function of adjusting the weight. Users can adjust the total weight of the dumbbell by changing the number of weight blocks clamped or replacing them with weight blocks of different masses, thereby meeting diverse exercise needs. However, this adjustment method is quite cumbersome and inefficient in actual operation.

[0003] First, whenever the weight of the dumbbell needs to be adjusted, the user usually needs to dismantle the entire clamping structure before removing, adding or replacing the weight block. After completing these operations, the clamping structure needs to be reinstalled to ensure that the weight block is firmly fixed. This series of steps is not only time-consuming and labor-intensive, but also significantly affects the user experience in scenarios where the weight is frequently adjusted.

[0004] In addition, the way the weight blocks are fixed in existing dumbbell designs also poses certain safety hazards. These weight blocks are usually only supported by a clamping and fixing structure to maintain a stable position. However, during use by users, under a single fixing method, the weight blocks are easily moved in position, and after long-term squeezing and collision with the clamping and fixing structure, the clamping structure is easily loosened, resulting in structural instability, affecting the exercise effect, and may also pose a threat to the safety of users. Utility Model Content

[0005] Aiming at the defects in the prior art, the utility model provides a novel dumbbell.

[0006] A new dumbbell comprises a hand-held handle, wherein both ends of the hand-held handle are provided with a support part, and both end surfaces of the hand-held handle are provided with an internal threaded hole, a bolt rod is passed through the internal threaded hole, the outer wall of the bolt rod is provided with an external thread matching the internal thread, and a pressing plate is fixed to the end of the bolt rod; wherein a support plate is clamped on the support part, and a first support hole is provided on the support plate; a plurality of weight plates that fit each other are arranged between the support plate and the pressing plate, a locking groove is provided at the bottom of the weight plate, and the bolt rod passes through the locking groove, a second supporting hole is provided on the left side of the weight plate, and a locking head is convexly provided on the right side of the weight plate, the second supporting hole of the weight plate is clamped into the locking head of an adjacent weight plate, and the locking head of the weight plate is clamped into the second supporting hole of the adjacent weight plate; the locking head on the weight plate contacting with the support plate is clamped into the first supporting hole.

[0007] Preferably, the support portion includes a support column protruding from the end of the hand-held handle, a support hole is provided in the center of the support sheet, and the support hole contacts the support column; wherein the end surface of the support column is provided with the internal threaded hole. This support column plays the role of connecting the hand-held handle and the weight plate. The design of the support column enables it to bear the weight of the dumbbell and transfer it to the hand-held handle, so that the user can hold the dumbbell stably for exercise; a support hole is provided in the center of the support sheet, and this support hole contacts the support column, ensuring that the support sheet can be accurately installed on the support column.

[0008] Preferably, an anti-slip layer is provided on the hand grip. When users do dumbbell exercises, their hands may sweat or feel tired due to holding the dumbbells for a long time. The anti-slip layer can effectively absorb sweat and increase friction, so that users can hold the dumbbells more firmly and reduce the risk of accidents or injuries caused by hand slippage.

[0009] Preferably, the weight plate is provided with a finger hole. When the user needs to adjust the weight of the dumbbell, the presence of the finger hole makes it easier to pick up and replace the weight plate. The user can insert a finger into the finger hole and easily pick up or put down the weight plate without having to pinch the entire weight plate, which greatly simplifies the process of adjusting the weight.

[0010] Preferably, at least two second supporting holes are provided on the weight plate, and the number of the positioning heads on the weight plate is the same as the number of the second supporting holes. By providing a plurality of second supporting holes on each weight plate and matching a corresponding number of positioning heads, the weight plate can be more stable during assembly. Each positioning head can be inserted into the second supporting hole of an adjacent weight plate to form a multi-point support, thereby effectively preventing the weight plate from shaking and falling off during use.

[0011] Preferably, the weight plate is also provided with a protective through hole, and the protective through holes of the plurality of weight plates form a protective channel, and a magnetic protective bolt is passed through the protective channel. The design of the protective through hole and the protective channel adds an extra layer of safety to the dumbbell. The magnetic protective bolt can pass through the protective channel to firmly connect the plurality of weight plates together, preventing them from accidentally separating or falling off during use or storage, thereby reducing the potential risk of injury.

[0012] The beneficial effects of the utility model are embodied in:

[0013] In the entire new dumbbell of the utility model, through the locking groove opened at the bottom of the weight plate, there is no need to remove the bolt rod and the pressing plate from the internal threaded hole. The weight plate can be removed or a new weight plate can be added by slightly unscrewing the bolt rod. When adding a new weight plate, it is only necessary to let the locking head on the newly added weight plate be locked into the second supporting hole of the outermost weight plate, which greatly simplifies the adjustment steps, improves the adjustment efficiency, optimizes the user's adjustment experience, and during the adjustment process, the weight plate will not contact the external thread on the outside of the bolt rod, avoiding affecting the external thread structure of the bolt rod; further, multiple weight plates are fitted together and cooperate with the locking heads on each weight plate. The weight plates are alternately inserted into the second supporting holes of adjacent weight plates, thereby greatly improving the overall stability of all the weight plates; more importantly, the positioning head is inserted into the first supporting hole so that all the weight plates are supported by the supporting plate, and the supporting plate is fixed on the supporting portion, that is to say, the hand holding handle directly supports all the weight plates, which on the one hand ensures that the weight plates will not contact the bolt rod and the external threads thereon, and on the other hand forms a more stable supporting force, and the clamping force of the pressing plate on the outermost weight plate after the bolt rod is tightened can ensure that the weight plates remain tightly and stably arranged during use, effectively preventing the weight plates from shifting and falling off, and greatly improving the safety of the dumbbells.
