Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] Such as figure 1 As shown, a kind of dumbbell of the present invention comprises dumbbell piece 1 and dumbbell bar 2, and described dumbbell piece 1 is arranged on the two ends of dumbbell bar 2 respectively, also includes balance instrument 3, alarm 4, groove one 5 and groove Groove two 6, the balancer 3 is arranged inside the dumbbell bar 2, the alarm 4 is arranged on the balancer 3, groove one 5 and groove two 6 are respectively arranged in two dumbbell pieces 1.

[0014] Preferably, the first groove 5 and the second groove 6 are equal in size.

[0015] Preferably, the alarm 4 is a vibration alarm.

[0016] By adding a balancer, an alarm, groove 1 and groove 2 to the existing dumbbells, after using the dumbbells for a long time, the general dumbbells will be worn out, and the balancer can be used to measure whether the weights of the dumbbell pieces on both side...

Abstract

The invention discloses dumbbell which comprises dumbbell pieces (1) and a dumbbell rod (2). The dumbbell pieces (1) are arranged at the two ends of the dumbbell rod (2) respectively. A balance instrument (3), an alarming device (4), a first groove (5) and a second groove (6) are further included. The balance instrument (3) is arranged in the dumbbell rod. The alarming device is arranged on the balance instrument. The first groove and the second groove are formed in the two dumbbell pieces respectively. The balance instrument, the alarming device, the first groove and the second groove are added in an existing dumbbell, after the dumbbell is used for a long time, a common dumbbell can be abraded, the balance instrument can be used for measuring whether the weights of the dumbbell pieces on the two sides are the same, if no, the alarming device can be driven to vibrate, scrap iron can be added into the first groove or the second groove if a dumbbell piece on one side is light, and the fact that the weights of the dumbbell pieces on the two sides are the same is guaranteed.

Description

technical field [0001] The invention relates to a dumbbell and belongs to the technical field of fitness equipment. Background technique [0002] Dumbbell is a simple equipment used to enhance muscle strength training. Its main material is cast iron, and some are covered with a layer of rubber. It is used for muscle strength training and muscle compound action training. Due to motor paralysis, pain, and long-term inactivity For patients with low muscle strength, hold dumbbells, and use the weight of kinetic dumbbells to perform active resistance exercises to train muscle strength. [0003] Dumbbells are an auxiliary equipment for weightlifting and fitness exercises that can be used in two ways: fixed weights and adjustable weights. Fixed-weight dumbbells, made of cast iron, with iron rods in the middle and solid balls at both ends; adjustable dumbbells, similar to reduced barbells, with round iron plates of different weights on both ends of short iron rods, long About 40 t...
