Abstract

The utility model relates to the technical field of sports training equipment, and discloses a resistance-adjustable sports training tension device which comprises a left handle and a right handle, wherein a plurality of tension ropes are arranged between the left handle and the right handle, and an adjusting assembly is arranged inside the left handle and the right handle. This sports training tension device of adjustable resistance carries out the rolling in advance to the pulling rope through the rolling pole, shortens the length of pulling rope, and shorter pulling rope means that the muscle needs to accomplish the shrink action in the shorter time to increase the resistance of training, and the dwang of right hand member can warp a plurality of pulling ropes together, makes intertwine, interweave between a plurality of pulling ropes, forms an holistic atress structure, can mutual constraint and collaborative deformation between each pulling rope under the exogenic action, not only can exert self bearing capacity, still has great frictional force between the pulling rope that twists together moreover.

Description

Sports training tension device with adjustable resistance Technical Field The utility model relates to the technical field of sports training equipment, in particular to a resistance-adjustable sports training tension device. Background Sports training equipment refers to various appliances and devices used during the course of sports training to assist the trainer in improving physical fitness, enhancing motor skills, and improving athletic performance. The prior patent (bulletin number: CN 213252782U) discloses a tension device for physical training, which comprises an elastic rope, a connecting block, a clamping column and a connecting belt, wherein the two sides of the elastic rope are respectively provided with a mounting structure, one end of the connecting block is fixedly connected with the clamping column, the top end and the bottom end of the connecting block are respectively fixedly connected with the connecting belt, the outer side wall of the connecting belt is fixedly connected with a fixing sheet, and the inner side wall of the connecting belt is provided with a grabbing structure. According to the elastic rope connecting device, the connecting block, the limiting block, the fixing bolt, the screw cap and the rubber ring are arranged, the connecting block is sleeved on the outer side wall of the elastic rope, connection with the elastic rope is reinforced, the fixing bolt penetrates through the connecting block, the fixing bolt is in threaded connection with the screw cap, the connecting block can be clamped and fixed in cooperation with the limiting block, the rubber ring is sleeved on the outer side wall of the fixing bolt, and when the rubber ring is extruded, the rubber ring is contracted inwards and expanded, and fixation with the connecting block is reinforced, so that the device is convenient to install. When the tension device is used, the tension rope and the two handles are fixedly connected into a whole, so that a user cannot flexibly adjust the tension degree, in the practical training process, the user is difficult to accurately adjust the resistance born during the tension training according to the current requirement of the user, after the user gradually adapts to the tension strength provided by the current equipment, the user needs to replace the training equipment with stronger resistance, and the training cost is increased, and a plurality of inconveniences are brought.
