[0030] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail by referring to the drawings.

[0031] Please refer to Figures 1-11As shown, the utility model provides a reliable adjustable dumbbell, including the base 1 of placing dumbbell piece 2, dumbbell piece 2, handle 3 and the chuck 34 of installing on the pole body 33, when handle 3 rotates, drive chuck 34 rotates, chuck 34 jams or stagger dumbbell piece 2, realize automatic adjustment dumbbell weight. Still including the self -locking module 32 of installing on the pole body 33, self -locking module 32 includes the stop disc 31, first lock disc 322, second lock disc 324, shell 321, lock block 326, cover plate 329 and fixed frame 327, first lock disc 322 is fixed in the inside of stop disc 31, second lock disc 324 is connected with stop disc 31, first lock disc 322, second lock disc 324 are all interval type and set the tab 3221, fixed frame 327 is fixed on cover plate 329, cover plate 329 seals fixed frame 327, first lock disc 322, second lock disc 324 in shell 321, lock block 326 is installed in fixed frame 327 through reset spring 325, stop disc 31 rotatablely installs on shell 321 and is connected with handle 3. Base 1 still is provided with lug 12, lock piece 11, when handle 3 rotates, drive stop disc 31, first lock disc 322, second lock disc 324 and tab 3221 rotate, when dumbbell is placed on base 1, the lug 12 on base 1 lifts lock block 326, so that the tab 3221 of second lock disc 324 can freely pass through the lock groove of lock block 326, handle 3 can be freely rotated and realizes weight adjustment;When dumbbell is separated from base 1, lock block 326 is pressed down by reset spring 325, so that the tab 3221 of second lock disc 324 jams lock block 326, second lock disc 324 cannot rotate, in turn cause handle 3 cannot rotate, dumbbell piece 2 cannot separate chuck 34. When the tab 3221 of first lock disc 322 jams with the lock piece 11 of base 1, the dumbbell is locked with base 1, and the dumbbell is fixed on the base 1. A plurality of grooves 13 are formed on the base 1 for placing the dumbbell pieces 2 to limit the loosening of the dumbbell pieces 2. The dumbbell pieces 2 are in the shape of 'U', and a sunken surface 22 is formed in the center to be attached to the chuck 34. The chuck 34 clamps the clamping block 21 protruding from the sunken surface 22 of the dumbbell piece 2 through a clamping ring 341.

[0032] As shown, Figure 4 The circumferential area occupied by the clamping ring 341 on the chuck 34 decreases from the direction close to the handle 3 to the direction away from the handle 3, thereby achieving weight adjustment of the dumbbell piece 2.

[0033] As shown, Figure 8 The inside of the tab 3221 of the second lock disc 324 is distributed with a ring-shaped through hole, and a top bead 328 is installed on the fixed frame 327 to abut against the through hole of the second lock disc 324. An elastic member 323 is also installed on the stop disc 31 to abut against the second lock disc 324, thereby reducing the friction when the second lock disc 324 rotates. Decorative covers 36 are installed at both ends of the pole body 33, and the decorative covers 36 are fixedly connected with the self-locking module 32 through connecting pieces 37.

[0034] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.

[0035] When using, place the dumbbells on base 1, as follows: Figures 9-11 As shown, the locking block 326 of the fixing frame 327 is lifted by the protrusion 12 of the base 1, and the protrusion 3221 of the second locking disc 324 can freely pass through the locking groove of the locking block 326. At this time, rotating the handle 3 will cause the stop plate 31 to rotate, and the first locking disc 322 fixed on the stop plate 31 will also rotate. The stop plate 31 also drives the second locking disc 324 and the transmission ends 342 of several chucks 34 to rotate in turn. Figure 4 As shown, when the retaining ring 341 of the chuck 34 rotates to the retaining block 21 of the dumbbell plate 2, it will lock the corresponding dumbbell plate 2, thereby changing the weight of the dumbbell.

[0036] If the pointer on the housing 321 is not aligned with the pointer on the gear shift 31 and is between two numbers, the protrusion 3221 of the first locking disc 322 will lock the locking piece 11 of the base 1, preventing the dumbbell from detaching from the base 1.

[0037] During exercise, rotating handle 3 sets the scale on the shift plate 31 to the corresponding weight. At this time, the first locking plate 322 is disengaged from the locking plate 11 of the base 1, allowing the dumbbell to be detached from the base 1. Figure 7 As shown. When the dumbbell detaches from base 1, as... Figure 8 , 11 As shown, the locking block 326 is pressed down by the reset spring 325, and the protrusion 3221 of the second locking disc 324 is stuck by the locking block 326. The second locking disc 324 cannot rotate, which in turn causes the handle 3 to be unable to rotate, and the dumbbell plate 2 cannot disengage from the chuck 34, thus achieving self-locking and ensuring safety.

[0038] Other embodiments of this invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the following claims.

[0039] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
