Description

Technical Field

[0001] This utility model relates to fitness equipment, and more particularly to dumbbells. Background Technology

[0002] Existing dumbbell bar designs have the following significant shortcomings:

[0003] 1. Small dumbbell head diameter: When the dumbbell plates are loaded with more than 20KG, the trainee will experience obvious discomfort and pressure during the training preparation phase (such as placing the dumbbells vertically above the thighs) due to the small dumbbell head area.

[0004] 2. Relying on external clips to secure dumbbell plates: Traditional clip structures are prone to aging and loosening over long-term use, reducing stability and increasing replacement frequency and operating costs. Furthermore, the thickness of the clips themselves encroaches on the space for the dumbbell plates, making it difficult to increase training weight. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a dumbbell bar that can quickly lock dumbbell plates of different thicknesses.

[0006] To solve the above-mentioned technical problems, the present invention provides a dumbbell bar, including: a bar body and an end cap assembly; the bar body has a gripping area and sleeves disposed on both sides of the gripping area; the side wall of the sleeve has a relief groove extending along the length direction, one end of the relief groove being connected to the end face of the sleeve away from the gripping area.

[0007] The end cap assembly includes an end cap detachably connected to the sleeve, an operating member, and a pressure block; the pressure block is placed inside the sleeve and extends to the outside of the sleeve through a relief groove, forming a clamping area for fixing dumbbell plates between the pressure block and the side of the sleeve near the gripping area; the operating member is reverse-coordinated with the pressure block to change the rotation of the operating member into the movement of the pressure block along the length direction of the sleeve, thereby changing the width of the clamping area.

[0008] In a preferred embodiment: the sleeve protrudes radially outward on the side near the gripping area to form a limiting surface.

[0009] In a preferred embodiment: a screw is fixedly disposed at the axis of the operating member, and the pressure block and the screw are connected by a thread to form a reversible engagement.

[0010] In a preferred embodiment: the side of the sleeve away from the gripping area is fixed to the end cap by a threaded connection.

[0011] In a preferred embodiment: the inner wall of the sleeve away from the gripping area is provided with internal threads, and the end cap protrudes axially along the side facing the sleeve to form a boss for inserting into the sleeve, and the outer wall of the boss is provided with external threads.

[0012] In a preferred embodiment: a sealing ring is provided at the connection between the boss and the end cap, and when the end cap is connected and fixed to the sleeve, the end face of the sleeve presses against the sealing ring.

[0013] In a preferred embodiment: the operating element is disposed on the side of the end cap away from the gripping area, the end cap is provided with a clearance channel along the thickness direction, and one end of the screw passes through the clearance channel and is placed in the sleeve.

[0014] In a preferred embodiment: the operating element is a turntable.

[0015] In a preferred embodiment, the diameter of the end cap assembly is larger than the diameter of the sleeve.

[0016] In a preferred embodiment, the operating element is located on the side of the end cap away from the gripping area.

[0018] This invention also provides a dumbbell, including dumbbell plates and a dumbbell bar as described above.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] 1. This utility model provides a dumbbell bar, which is fixed by an end cap and the bar body. Rotating the operating component in the end cap assembly moves the pressure block along the length of the sleeve, thereby changing the distance between the pressure block and one side of the sleeve, and thus adjusting the width of the clamping area for placing dumbbell plates. This allows for free adjustment of the weight of the dumbbell plates placed on the dumbbell bar, achieving locking of dumbbell plates of different thicknesses. Furthermore, this locking structure uses compression locking, eliminating the need for external clips, and ensuring reliable locking even after long-term use.

[0021] 2. This utility model provides a dumbbell bar, with the end cap, operating component and pressure block forming a complete end cap assembly. During installation and disassembly, the end cap assembly can be installed or disassembled as a whole, realizing integrated installation and disassembly.

[0022] 3. This utility model provides a dumbbell bar with an operating component located on the outermost side of the end cap assembly. By increasing the diameter of the operating component, the contact area between the dumbbell bar and the user when placed vertically can be increased, thereby reducing the pressure exerted by the dumbbell bar on the user. For example, when a user places the dumbbell bar vertically on their thigh during training, the operating component can reduce the pressure exerted by the dumbbell bar on the user, thereby improving comfort and stability.

[0031] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0032] refer to Figures 1-8This embodiment provides a dumbbell, including dumbbell plates 1 and a dumbbell bar 2. The dumbbell plates 1 can be mounted on the dumbbell bar 2 to assemble a complete dumbbell. The dumbbell bar 2 in this embodiment can achieve quick installation and removal of dumbbell plates 1 of different numbers or thicknesses. To this end, the dumbbell bar 2 includes: a bar body 21 and an end cap assembly 22; the bar body 21 has a gripping area 211 and sleeves 212 disposed on both sides of the gripping area 211. The gripping area 211 is provided with anti-slip protrusions, which can increase the friction between the user's palm and the bar body 21, making it less likely for the barbell to slip during use; the sleeves 212 are used to cooperate with the opening at the center of the dumbbell plates 1, allowing the dumbbell plates 1 to be fitted onto the sleeves 212. The sleeve 212 has a relief groove 213 extending along the length direction on its side wall. One end of the relief groove 213 is connected to the end face of the sleeve 212 away from the gripping area 211, so that the relief groove 213 is U-shaped.

[0033] The above structure allows the dumbbell plate 1 to be fitted onto the sleeve 212, but it cannot fix the dumbbell plate 1 to the bar 21. Therefore, the end cap assembly 22 described above is still needed to fix the dumbbell plate 1. Specifically, the end cap assembly 22 includes an end cap 221 detachably connected to the sleeve 212, an operating member 222, and a pressure block 223. The pressure block 223 is placed inside the sleeve 212 and extends to the outside of the sleeve 212 through a relief groove 213. A clamping area for fixing the dumbbell plate 1 is formed between the pressure block 223 and the side of the sleeve 212 near the gripping area 211. The operating member 222 and the pressure block 223 are reversed to change the direction of rotation of the operating member 222 into movement of the pressure block 223 along the length direction of the sleeve 212, thereby changing the width of the clamping area. In other words, by rotating the operating component 222, the user can move the pressure block 223 along the sleeve 212, causing the pressure block 223 to abut against the dumbbell plate 1. This clamps the dumbbell plate 1 between the pressure block 223 and the sleeve 212 on the side near the gripping area 211, thus fixing the dumbbell plate 1. This allows for free adjustment of the weight of the dumbbell plate 1 placed on the dumbbell bar 2, enabling locking of dumbbell plates 1 of different thicknesses. Furthermore, this locking structure uses compression locking, eliminating the need for external clips and ensuring reliable locking even after long-term use.

[0034] Furthermore, the end cap 221, the operating element 222, and the pressure block 223 form a complete end cap assembly 22. During installation and disassembly, the end cap assembly 22 can be installed or disassembled as a whole, achieving integrated installation and disassembly. By connecting one end of the relief groove 213 to the end face of the sleeve 212 away from the gripping area 211, the pressure block 223 can be detached from one end of the relief groove 213, thereby allowing the end cap assembly 22 to be removed from the rod body 21 as a whole.

[0035] To prevent the dumbbell plate 1 from sliding off the sleeve 212 into the gripping area 211, the sleeve 212 protrudes radially outward on the side near the gripping area 211 to form a limiting surface 214. The outer diameter of the limiting surface 214 is larger than the diameter of the opening at the center of the dumbbell plate 1, so the limiting surface 214 can abut against the dumbbell plate 1 and limit its movement, preventing the dumbbell plate 1 from sliding into the gripping area 211.

[0036] To enable the operating component 222 to rotate and drive the pressure block 223 to move along the length of the sleeve 212, a screw 224 (not shown in the attached figure) is fixedly installed at the axis of the operating component 222. The pressure block 223 and the screw 224 are connected by a thread to form a reversible engagement. When the operating component 222 rotates, the screw 224 rotates together with the operating component 222. Through the threaded engagement between the pressure block 223 and the screw 224, the pressure block 223 can be driven to move along the length of the screw 224 when the screw 224 rotates. Since the screw 224 is inserted into the sleeve 212, the pressure block 223 also moves along the length of the sleeve 212.

[0037] In the above structure, the end cap 221 and the sleeve 212 must first be fixed so that the screw 224 in the operating member 222 can be inserted into the sleeve 212. Then, the operating member 222 can be rotated to drive the screw 224 to rotate, thereby causing the pressure block 223 to move along the length of the sleeve 212. In order to fix the end cap 221 and the sleeve 212, in this embodiment, the side of the sleeve 212 away from the gripping area 211 is fixed to the end cap 221 by a threaded connection to form a detachable connection relationship.

[0038] Specifically, the inner wall of the sleeve 212 away from the gripping area 211 has an internal thread 2121. The end cap 221 protrudes axially along the side facing the sleeve 212 to form a boss 2211 for inserting into the sleeve 212. The outer wall of the boss 2211 has an external thread 2212. Furthermore, a sealing ring 2213 is provided at the connection between the boss 2211 and the end cap 221. When the end cap 221 is connected and fixed to the sleeve 212, the end face of the sleeve 212 presses against the sealing ring 2213. Through the internal thread 2121, the external thread 2212, and the sealing ring 2213, a reliable and stable connection can be formed between the sleeve 212 and the end cap 221.

[0039] Furthermore, the operating member 222 is located on the side of the end cap 221 away from the gripping area 211. The end cap 221 has a clearance channel extending through it along its thickness direction. One end of the screw 224 passes through the clearance channel and is placed in the sleeve 212. Therefore, the operating member 222 can rotate relative to the end cap 221. After the end cap 221 and the sleeve 212 are fixed, rotating the operating member 222 will allow the pressure block 223 to move along the length direction of the screw 224.

[0040] In this embodiment, the operating component 222 is a turntable with an arc-shaped outer periphery for easy rotation by the user. Furthermore, the diameter of the end cap assembly 22 is larger than the diameter of the sleeve 212. In particular, the larger diameter of the operating component 222 increases the contact area between the dumbbell bar 2 and the user when placed vertically, thereby reducing the pressure exerted by the dumbbell bar 2 on the user. For example, when the user places the dumbbell bar 2 vertically on their thigh during training, the operating component 222 can reduce the pressure on the user, thus improving comfort and stability.

[0041] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
