[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 A postoperative chest expansion training device includes a frame 1. A seat 2 is fixedly installed on the front wall of the frame 1 for the patient to sit on. A backrest 3 is fixedly installed on the front wall of the frame 1 above the seat 2 for the patient to lean against. A fixed shell 4 is fixedly installed on the rear wall of the frame 1. A support rod 8 is fixedly installed on the back of the frame 1. A guide wheel 9 is rotatably connected to the support rod 8 and can rotate. A mounting hole 12 is opened on the bottom wall of the frame 1.
[0020] Please see Figure 1-4 The frame 1 and the fixed shell 4 are equipped with a chest expansion assembly 5 for chest expansion training. The chest expansion assembly 5 includes a movable shaft 51, a movable rod 52, a grip bar 53, a gear 54, a movable wheel 55, a connecting rope 56, a drop plate 57, and a spring 58. The movable shaft 51 is rotatably connected to the top wall of the frame 1. The movable rod 52 is fixedly installed on the outer surface of the movable shaft 51 and can rotate with the movable shaft 51. The movable rod 52 is located on the inner side of the frame 1. The side wall of the frame 1 is fixedly connected to a stop block 7 corresponding to the movable rod 52. After hitting the stop block 7, it is blocked and cannot continue to rotate backward. The outer surface of the grip bar 53 is equipped with a grip sleeve 6 for easy hand gripping. The gear 54 is fixedly installed on the outer surface of the movable shaft 51 and can rotate around the movable shaft 51. There are two movable shafts 51 and two gears 54. The two gears 54 mesh externally, allowing the movable rods 52 on both sides to rotate synchronously and perform chest expansion and contraction training together. The gears 54 are located above the frame 1.
[0021] Furthermore, the movable wheel 55 is fixedly installed on the top of the movable shaft 51 and can rotate with the movable shaft 51. The connecting rope 56 is wrapped around the outer surface of the movable wheel 55. The rotation of the movable wheel 55 can pull the connecting rope 56. The connecting rope 56 is connected to the outer surface of the guide wheel 9. The drop plate 57 is slidably connected to the inner wall of the fixed shell 4. The drop plate 57 can move up and down. The shape of the drop plate 57 is a quadrangular prism. The tail of the connecting rope 56 is fixedly connected to the drop plate 57 and can pull the drop plate 57 upward. The connecting rope 56 passes through the top wall of the fixed shell 4. The spring 58 is fixedly installed between the inner top wall of the fixed shell 4 and the opposite side of the drop plate 57. Under the elastic force of the spring 58 and the weight of the drop plate 57 itself, the movable rod 52 and the grip rod 53 can be reset, which is conducive to the patient repeating chest expansion training. The connecting rope 56 is located inside the spring 58.
[0022] Please see Figure 1-4An adjustment component 10 is provided on the movable rod 52. The adjustment component 10 includes a threaded rod 101 and a movable block 102. The threaded rod 101 is threadedly connected to the movable rod 52. A handle is fixedly installed at the end of the threaded rod 101 to facilitate rotation of the threaded rod 101. The movable block 102 is rotatably connected to the end of the threaded rod 101. When the threaded rod 101 rotates, it drives the movable block 102 to move. The grip 53 is rotatably connected to the end of the movable block 102. The movement of the movable block 102 can adjust the straight-line distance between the grip 53 and the hand, thereby adapting to people with different arm lengths and improving the applicability of the chest expansion training mechanism. An opening 11 is provided on the movable rod 52 to slide and connect with the movable block 102, allowing the movable block 102 to move along the movable rod 52.
[0023] In this embodiment, when in use, the patient sits on the seat 2 with their back against the backrest 3. Rotating the threaded rod 101 moves the movable block 102 and the grip bar 53, allowing the patient's hands to grip the grip sleeve 6. The patient's arms pull the grip bars 53 together, and with the meshing of the gears 54, the movable wheel 55 rotates, pulling the connecting rope 56, causing the drop plate 57 to move upward and the spring 58 to be compressed. Then, the patient's arms pull the grip bars 53 apart. With the patient's back-and-forth pulling and opening, chest expansion training is achieved.
[0024] The beneficial effects of the above embodiments are as follows:
[0025] This postoperative chest expansion training mechanism, through the setting of the unfolding component 5, allows for synchronous chest expansion training by pulling the grips 53 with both hands under the meshing of the gears 54. This ensures that the grips 53 on both sides can open and close synchronously, guaranteeing the coordination of the chest expansion training. In addition, the connecting rope 56 is wrapped around the movable wheel 55, and under the weight of the drop plate 57 and the elasticity of the spring 58, the arms are subjected to a certain degree of load every time the grips 53 are pulled, thereby improving the patient's tolerance to chest expansion training.
