Abstract

The invention is applicable to the technical field of fitness, and provides a counterweight box for stretching exercise equipment. The weight box comprises a box body; a location-limited plate and a counterweight water tank are disposed in the box body; a pair of fixing rods are mounted between the location-limited plate and the bottom of the box body; sliding channels are disposed between the fixing rods; a auxiliary water tank is further disposed above the location-limited plate; a water pipe is disposed downwardly from the bottom of the auxiliary water tank; the water pipe extends into thecounterweight water tank; a water pump is further disposed on the water pipe; vertical racks are disposed at two sides of the counterweight water tank; cross sections of the fixing rods are of U-shaped groove structures; gears are mounted in the U-shaped groove structures; a plurality of through holes are formed in the gears by taking gear shafts as the centers of circles; a pair of optical transceiving sensors are disposed at top ends of the U-shaped groove structures; a pair of oil hydraulic cylinders are further mounted in each of the U-shaped groove structures; a rang sensor is disposed onthe location-limited plate; and a control box is disposed on the side wall of the box body. A method of changing the weight of the counterweight water tank is simple, so that the stretching exerciseeffect of a human body is better.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, in particular to a weight box for stretching exercise equipment. Background technique [0002] In fitness equipment, various arm strength, leg strength and waist strength stretching exercises often use counterweight boxes as weight equipment to provide resistance. The current counterweight box increases weight by adding counterweights, thereby increasing resistance. This method operates Not only is it complicated, but the counterweight is also easy to lose and damage, making it inconvenient to use. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a weight box for stretching exercise equipment, which aims to solve the technical problems of the existing weight box such as complicated ways of adding weight and inconvenient use. [0004] The present invention adopts following technical scheme: [0005] The counterweight...
