Problems solved by technology

In the first type of weight-fixed dumbbell, since the weight is not adjustable, the user must prepare a set of dumbbells to meet the needs of use, so the cost is high and the space occupied is relatively large.
In the second type of weight-adjustable dumbbell, it includes multiple weight plates and handles, and the multiple weight plates are symmetrically connected at both ends of the handle. There is a central hole in the middle of the dumbbell weight plates. The heavy pieces are worn one by one at the two ends of the handle and fastened with locking devices such as nuts. Therefore, the use of dumbbells with this structure is very inconvenient

Abstract

The invention discloses a weight adjustable dumbbell which comprises a handle sleeve (4), a connecting rod (8) and a plurality of weight balance pieces (2), each group of weight balance piece connecting device comprises a weight balance piece support frame, a locking device and a piece selecting device provided with a piece selecting shaft (3), the weight balance piece support frame is connected to the end part of the connecting rod (8), the piece selecting shaft (3) is located in the weight balance piece support frame and is connected in a sleeving manner on the connecting rod (8), the piece selecting shaft (3) is connected with the weight balance pieces (2) through bulges (3.1) on the peripheral wall, one end of the piece selecting shaft (3) is connected with the handle sleeve (4), the handle sleeve (4) is rotatably connected outside the connecting rod (8), and the locking device is located in the balance weight piece support frame and is locked and connected with the piece selecting device. After the adoption of the structure, as the piece selecting shaft is connected with the balance weight pieces through the bulges and the gear of weight is selected through the handle sleeve, the operation is very convenient, and the structure is simpler.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a weight-adjustable dumbbell. Background technique [0002] At present, the dumbbells on the market are divided into two types, one is weight-fixed, and the other is weight-adjustable. Under normal circumstances, the weight of dumbbells is divided into 5LB, 10LB, 15LB, etc., and the weights commonly used by ordinary people are 5LB, 10LB, 15LB, and 20LB. In the first type of weight-fixed dumbbell, since the weight is not adjustable, the user must prepare a set of dumbbells to meet the needs of use, so the cost is high and the space occupied is relatively large. In the second type of weight-adjustable dumbbell, it includes multiple weight plates and handles, and the multiple weight plates are symmetrically connected at both ends of the handle. There is a central hole in the middle of the dumbbell weight plates. The heavy sheet is fastened with a locking device such as a...
