Description

Dumbbell with adjustable weight

Technical Field

The utility model relates to a body-building apparatus technical field, what specifically say is a dumbbell of adjustable weight.

Background

The dumbbell is a common fitness apparatus and is mainly used for muscle strength training, muscle compound action training and the like. Especially for users with low muscle strength caused by paralysis, pain, long-term inactivity and the like, the dumbbell can be held by hands, resistance active exercise can be carried out by using the weight of the dumbbell, and muscle strength is trained and enhanced. The prior art dumbbells have dumbbells with fixed weight and dumbbells with adjustable weight, when the dumbbells with fixed weight are used, a user needs to prepare a set of dumbbells with different weight specifications to meet the use requirement, so the use of the dumbbells with fixed weight increases the purchase cost of the user and occupies more storage space; the dumbbell with adjustable weight generally adopts a plurality of counter weights with different weights to be connected with the grab handle, and the weight of the dumbbell is adjusted by adjusting the number of the counter weights. For example, patent application with publication number CN104548480A and name of dumbbell, the structure of dumbbell comprises a dumbbell rod, wherein two ends of the dumbbell rod are provided with external threads, the external threads are sleeved with a plurality of dumbbell cakes, the outermost sides of the dumbbell cakes are provided with stop blocks which are sleeved on the external threads of the dumbbell rod, and the dumbbell cakes are hexagonal. The dumbbell with the structure is in threaded connection with the external thread of the dumbbell rod through the stop block to compress dumbbell cakes, and the weight of the dumbbell is adjusted by adjusting the number of the dumbbell cakes; also disclosed in application No. CN210278094U entitled dumbbell with adjustable weight is a dumbbell whose weight is adjusted by providing a first adjustment stop, a second adjustment stop, and four weight adjustment blocks. When the weight is full, a first stop ring of the first adjusting stop and a second stop ring of the second adjusting stop are respectively matched with two ends of the iron column, a first balancing weight, a second balancing weight, a third balancing weight and a fourth balancing weight are arranged in a balancing cavity of the shell, and the bottom cover and the top cover are respectively in threaded connection with the shell; and at half weight, the first stop ring of the first adjusting stop is contacted with the first balancing weight, the second stop ring of the second adjusting stop is contacted with the fourth balancing weight, the non-stop ring sides of the first adjusting stop and the second adjusting stop are contacted with the two ends of the iron column, and the bottom cover and the top cover are respectively in threaded connection with the shell. Another patent application, publication No. CN204034145U entitled dumbbell with adjustable weight, adjusts the weight of a dumbbell by filling a hollow dumbbell head with fillers of different weights. The dumbbell with the weight adjustable in the prior art has the following defects in the using process: the counterweight block is connected with the grab handle insecurely, and the counterweight block is easy to fall off and injure a user in the using process; in addition, when the dumbbell is used, noise is generated due to the shaking of the balancing weight, so that the user experience is poor; furthermore, a plurality of balancing weights are sequentially overlapped on the grab handle along the thickness direction, so that the gravity center of the unilateral balancing weight of the dumbbell is far away from the center of the grab handle, the use is inconvenient, especially for women, and the operation is very inconvenient.
