Description

Technical Field

[0001] The utility model relates to a barbell clamp structure. Background Art

[0002] A barbell is a common fitness equipment, which mainly consists of a pull rod and multiple weight plates. When using it, users need to adjust the number of weight plates according to their own situations. In reality, dumbbells basically appear at the same time as barbells. The difference between them lies in the length of the pull rod, and they usually share the weight plates. This will result in that when users practice with dumbbells, they need to install the weight plates on the dumbbell pull rod, and when they need to practice with barbells, they need to remove the weight plates from the dumbbells and install them on the barbell pull rod, which is very time-consuming and laborious, and will undoubtedly delay strength training.

[0003] Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems and provide a barbell clamp structure, which solves the problem that users frequently disassemble and assemble weight plates.

[0011] The beneficial effects of the present utility model compared with the background art are as follows: By adopting this barbell clamp structure, the problem that users frequently disassemble and assemble the dumbbell plates is solved. This barbell clamp can directly fix the dumbbell without disassembling the dumbbell plates on the dumbbell, saving the time for disassembling and assembling the dumbbell plates and improving the convenience of use. Description of the Drawings

[0012] Figure 1 It is a schematic structural view of the barbell clamp according to an embodiment of the present utility model;

[0013] Figure 2 It is a schematic view before the first rod body and the second rod body of the embodiment of the present utility model are assembled. Detailed Description of the Embodiment

[0014] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not limit the protection scope of the present utility model.

[0015] Please refer to the attached Figure 1 This application provides a barbell clamp structure, which includes a pull rod and clamp frames connected to both ends of the pull rod. The clamp frames include a first clamping portion 1, a second clamping portion 2 and a knob 3. The first clamping portion has a stud 4 passing through the pull rod. The second clamping portion 2 is cooperatively connected with the first clamping portion 1 to enclose a clamping cavity 5. The clamping cavity can clamp the handlebar on the dumbbell. When both clamp frames respectively clamp the dumbbell, the use of the barbell is formed. The second clamping portion 2 has an assembly hole 6 for the stud to pass through. The second clamping portion can rotate relative to the first clamping portion to open the clamping cavity 5. The knob 3 is screwed to the stud and maintains the connection state between the first clamping portion and the second clamping portion. During installation, first rotate the second clamping portion to open the clamping cavity, then place the handlebar on the dumbbell on the first clamping portion, and then connect the second clamping portion with the first clamping portion by rotation to clamp the handlebar of the dumbbell. At this time, the stud has passed through the assembly hole, and the user only needs to screw the knob onto the stud to maintain the connection state between the first clamping portion and the second clamping portion.

[0016] The knob 3 is made of plastic, and a nut screwed to the stud 4 is provided inside the knob. The nut and the knob are preferably an integrally injection-molded structure. The outer shape of the knob is in the shape of a plum blossom, and the plum blossom-shaped outer shape of the knob is more convenient for the user to exert force to rotate.

[0017] The first clamping portion 1 has a first pivot portion 7, and the second clamping portion 2 has a second pivot portion 8. The first pivot portion and the second pivot portion are connected by a pivot shaft 9. The pivot connection structure can reliably and smoothly realize the rotation of the second clamping portion relative to the first clamping portion.

[0018] An elastic clamping part 10 is provided on the inner sides of the first clamping part 1 and the second clamping part 2. The elastic clamping part can clamp the handlebar of the dumbbell more firmly when clamping the handlebar, so as to prevent it from rotating or shifting. The elastic clamping part can specifically be plastic.

[0019] The first clamping part 1 has a first arc-shaped fitting part 101 that fits the surface of the pull rod, and the stud 4 is arranged on the first arc-shaped fitting part; the second clamping part 2 has a second arc-shaped fitting part 201 that fits the surface of the pull rod, and the assembly hole 6 is opened on the second arc-shaped fitting part. Adopting this structure can improve the connection tightness between the clamp and the pull rod.

[0020] Please refer to Figure 2 , the pull rod includes a first rod body 11 and a second rod body 12. The first rod body and the second rod body are spliced together through a screw connection structure. A stud structure is provided on the first rod body, and a screw connection cavity that cooperates with the stud structure is provided on the second rod body.

[0021] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention shall be included in the protection scope recorded in the claims.
