Description

Elastic section resistance training device Technical Field The utility model relates to the technical field of medical equipment, in particular to an elastic section resistance training device. Background The elastic section is used as a rehabilitation device frequently to be used, and the length of the elastic section can be shortened to realize the adjustment of the resistance of the elastic section when the conventional elastic section device is used, but the following problems exist in the actual operation process: 1. Because the leg lengths of different patients are different, the length of the elastic section needs to be adjusted, when the length of the elastic section is shorter and the leg length of the patient is longer, the condition that the leg of the patient cannot be fully stretched easily occurs, so that the exercise effect of the patient is affected; 2. Because the exercise intensity required by different patients is different, when the resistance of the elastic section is increased to shorten the length of the elastic section, the situation that the legs of the patients cannot be fully stretched due to the shorter length of the elastic section after being shortened can occur, so that the exercise effect of the patients is affected; 3. Because the elasticity of the elastic section is easy to lose after long-time use, and the service lives of other parts are longer, the existing device cannot be used after the elasticity of the elastic section is lost, and the service life of the device can be influenced. Disclosure of utility model In order to solve the above problems, an object of the present utility model is to provide an elastic segment resistance training device that can adjust the resistance of an elastic segment with the length of an elastic endless belt unchanged. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The elastic section anti-resistance training device comprises a bottom plate, a pushing mechanism and a training mechanism, wherein the pushing mechanism is slidably arranged on the upper surface of the bottom plate, the training mechanism is fixedly arranged on the upper surface of the pushing mechanism, the training mechanism comprises a mounting plate fixedly arranged on the upper surface of a pushing assembly, an elastic belt ring movably sleeved on the mounting plate and limiting assemblies detachably arranged on the mounting plate and matched with the elastic belt ring to realize resistance adjustment, the elastic belt ring is composed of elastic sections and inelastic sections which are connected end to end, limiting rings which are fixedly arranged at intervals are penetrated through the elastic belt ring, the limiting assemblies comprise a pair of limiting rods vertically movably sleeved on the mounting plate and a connecting plate fixedly arranged between the upper end surfaces of the two limiting rods, a pair of left-right symmetrical limiting through grooves are formed in the front top of the mounting plate, the elastic belt ring is movably sleeved on the two limiting through grooves, slots matched with the limiting rods are formed in the bottoms of the limiting through grooves, and the lower parts of the limiting rods penetrate through the limiting rings on the corresponding sides and are inserted into the slots.
