Description of reference numerals:
1 holding rod, 2 dumbbell pieces, 21 sliding blocks, 3 auxiliary rods, 4 sliding grooves, 41 long grooves, 42 short grooves, 43 transition grooves, 5 locking nuts and 6 springs.
Detailed Description
The utility model will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-2, a dumbbell convenient to install comprises a holding rod 1 and dumbbell pieces 2, wherein auxiliary rods 3 are arranged on two sides of the holding rod 1, a pair of hook-shaped sliding grooves 4 are respectively formed in the auxiliary rods 3, each sliding groove 4 comprises a long groove 41 and a short groove 42, the long grooves 41 and the short grooves 42 are communicated through transition grooves 43, the long grooves 41 are communicated with the outside, two sides of each auxiliary rod 3 are respectively in threaded connection with a locking nut 5, a sliding block 21 is arranged on the inner side of each dumbbell piece 2, each dumbbell piece 2 slides into the corresponding long groove 41 through the corresponding sliding block 21 and then enters the corresponding short groove 42 through the corresponding transition groove 43 to be installed, and the corresponding locking nut 5 limits the dumbbell piece 2 in the corresponding sliding groove 4 and fixes the dumbbell piece. Specifically, the dumbbell piece 2 is sleeved on the auxiliary rod 3, the sliding block 21 slides into the long groove 41, the dumbbell piece 2 is rotated, the sliding block 21 enters the short groove 42 through the degree groove 43 and moves to the tail end of the short groove 42, and the dumbbell piece 2 is fixed through the locking nut 5.
In this embodiment, the spring 6 is disposed inside the lock nut 5, and the spring 6 is sleeved on the secondary rod 3, so that the dumbbell sheet 2 is squeezed by the spring 6. The spring 6 can extrude the dumbbell sheet 2 and simultaneously prevent the locking nut 5 from loosening.
In this embodiment, the slider 21 is in clearance fit with the chute 4. The clearance fit between the dumbbell piece and the dumbbell piece is reduced as much as possible, and the dumbbell piece 2 is prevented from shaking in the using process.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
