High-safety barbell rod and barbell

Abstract

The high-safety barbell rod comprises a barbell rod body, one end of the barbell rod body is in threaded connection with a barbell disc, a first clamping groove is formed in one side of the barbell disc in a clamped mode, a clamping plate is slidably connected to the interior of the first clamping groove, a weight increasing piece is fixedly connected to one side of the clamping plate, and a second clamping groove is formed in one side of the weight increasing piece; threaded holes are formed in the weight increasing pieces, a cavity is formed in the barbell rod, and a fixing rod is inserted into the cavity. According to the weight increasing device, a user clamps the clamping plates into the first clamping grooves in one sides of the barbell discs, so that the weight increasing pieces are clamped to one sides of the barbell discs for weight increasing, the clamping plate on one side of the other weight increasing piece is clamped into the second clamping groove in one side of the first weight increasing piece, the fixing rods are inserted into the threaded holes, and the weight increasing pieces are clamped into the second clamping grooves in one side of the first weight increasing piece; the fixing rod is inserted into the cavity in the barbell rod all the time, the rotating handle is held tightly, the fixing rod is rotated, and the fixing threads on the surface of the fixing rod are connected into the threaded hole.

Description

technical field [0001] The invention relates to the field of barbells, in particular to a high-safety barbell bar and a barbell. Background technique [0002] Barbell is a kind of core training sports training equipment, and it is also the equipment used for weightlifting. Barbell exercise is a kind of weight training. It only uses barbell training equipment to enhance muscle strength training, and can also use barbell for core training to promote overall coordination. , The barbell has a wide range of uses, whether it is the muscles of the shoulders, back, arms, chest, etc., with the help of barbells and iron plates of different weights, using multiple times of special training techniques for muscle strength, muscle endurance training for the whole body muscles, Burn fat and convert it into a fit line, strengthen muscle strength, strengthen the body's core ability, and improve the local muscles that are still loose after long-term exercise; in addition, it can also delay mu...
