Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, in particular to an abdominal and back muscle trainer. Background Art

[0002] An abdominal and back muscle trainer is a piece of fitness equipment specially designed for exercising the abdominal and back muscle groups. This type of equipment usually helps users train their abdominal and back muscles more safely and effectively by providing specific movement trajectories, adjustable resistance, and auxiliary support.

[0003] In the prior art, a rotating arm tube is usually rotatably arranged on a support frame, a rotating sleeve support tube is arranged on the rotating arm tube, and a rotating sleeve is arranged on the rotating sleeve support tube, so that the user can perform training. However, in this method, the rotating sleeve support tube is usually fixed on the rotating arm tube, which makes it inconvenient to adjust the height of the rotating sleeve. The difficulty of training depends not only on the weight or resistance used, but also on the range of motion and joint angle. The fixed-height rotating sleeve limits the possibility of users adjusting the range of motion, making it difficult to gradually increase the challenge of training according to their own training level and progress. Utility Model Content

[0004] In view of this, the utility model aims to provide an abdominal and back muscle trainer to address the deficiencies in the prior art. The utility model can not only adjust the height of the rotating sleeve through an adjustment component, and then make personalized adjustments according to the height differences of users to improve training efficiency and safety, but also can display quantitative information related to training through an instrument, so that users can directly read these data through the instrument and grasp their training progress and intensity in real time.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an abdominal and back muscle trainer, including a base plate, a support frame 1 is arranged on the right side of the rear end of the base plate, a bearing seat is arranged on the upper end of the support frame 1, a support tube 1 is rotatably arranged on the bearing seat, a rotating arm tube is arranged on the support tube 1, a fan-shaped adjustment plate is rotatably arranged on the upper end of the rotating arm tube, a rotating sleeve support tube is arranged on the fan-shaped adjustment plate, a rotating sleeve is arranged on the rotating sleeve support tube, an adjustment component for adjusting the angle of the fan-shaped adjustment plate is arranged on the rotating arm tube, the adjustment component includes a through hole 1 arranged at the upper end of the rotating arm tube, a plurality of through holes 2 matched with the through hole 1 are opened on the fan-shaped adjustment plate, and the through hole 1 and the through hole 2 are fixedly connected by an adjustment pin.

[0011] As a further improvement of the utility model, a plurality of pads are arranged at the lower end of the bottom plate, and mounting holes three are arranged on the pads.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Firstly, by setting an adjustment component, when the height of the rotating sleeve needs to be adjusted, the adjustment pin is removed, and then the adjustment plate is rotated to change the height of the rotating sleeve support tube on the adjustment plate. When it is rotated to a suitable position, the adjustment pin is inserted into through hole one and through hole two to adjust the height of the rotating sleeve, and then personalized adjustments are made according to the height differences of users to ensure that the distance between various parts of the body and the key components of the trainer during training is appropriate. This can ensure that users maintain a correct posture during training, avoid discomfort or sports injuries caused by inappropriate equipment size, and improve training efficiency and safety.

[0014] Secondly, by setting up the instrument, which is usually used to display quantitative information related to training, users can directly read these data through the instrument when using the abdominal and back muscle trainer, and grasp their training progress and intensity in real time, which helps to accurately control the training volume and achieve personalized and scientific training goals.

[0015] Third, by setting up a mobile phone holder, users can fix their mobile phones on the holder, making it convenient to directly view and operate various fitness applications during training.

[0016] Fourthly, a plurality of pads are provided at the lower end of the bottom plate, which can effectively disperse the pressure of the trainer on the ground, reduce the direct contact area, and prevent the heavy trainer from causing scratches, indentations or permanent damage to the floor.
