Abstract

The invention relates to a weightlifting device, which comprises a base, a supporting device, a first connecting shaft, a second connecting shaft, a first incomplete gear, a first bevel gear, a firsttorsion device, a second incomplete gear, a second bevel gear, a lifting structure and a holding rod, wherein the base comprises a base plate;the supporting device comprises two supporting rods and aplurality of transmission pieces; the first torsion device comprises an upper torsion cover, an outer torsion cylinder and a torsional spring; the lifting structure comprises a shell body, a verticalplate, racks and a supporting rod hole, the shell body is driven to move upwards when the holding rod is lifted by a hand; the first incomplete gear and the second incomplete gear are made to rotate reversely by means of the two racks; and then the first bevel gear and the second bevel gear are driven to rotate reversely, and the torsional spring generates torque. According to the weightlifting device, the torsional spring is used for increasing the weight, namely, the weightlifting force acts on the torsional spring, so that a balancing weight is omitted, the occupied area of the weightlifting device is reduced, the space is saved, the condition that the balancing weight slips off is avoided, and the use safety is improved.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a weight-lifting device. Background technique [0002] With the development of society, fitness is becoming more and more important in people's lives, and the types of fitness equipment are also rich and colorful, but the existing weightlifting devices need to be used in conjunction with counterweights, and counterweights are easy to fall off when used improperly, resulting in easy Injury, when the middle object is too large, it will affect the appearance, and it is not easy to transport. In addition, the use mode of the weight lifting device is single, which cannot meet the different requirements of users. Contents of the invention [0003] The invention provides a weight-lifting device to solve the unsafe problem of the existing weight-lifting device. [0004] A kind of weightlifting device of the present invention adopts following technical scheme: [0005] A weightlifting...
