Description

Technical Field

[0001] The utility model relates to the field of treadmills, in particular to a treadmill that can be used for rehabilitation exercises. Background Art

[0002] Treadmills are common fitness equipment in homes and gyms. They can adjust to a variety of running environments to meet the needs of various types of users. They have a very good effect on training the user's lower limbs and aerobic consumption of the whole body.

[0003] In order to prevent users from accidentally falling and getting injured while running, current treadmills are equipped with handles on the treadmill frame to provide users with support and balance. The structure and function of such handles are relatively simple. When running with the handles as support, the user's hands and arms remain basically still, which is not conducive to fat burning in the upper body. In addition, for some users who need to use a treadmill to rehabilitate their physical functions, the existing treadmill handles do not have the ability to assist users in exercising their arms.

[0004] Therefore, in order to address the problem that the handle structure of the above-mentioned existing treadmill has a single function and is unable to assist users in arm rehabilitation training, a treadmill with a rehabilitation structure on the handle can be designed to help users exercise their arms properly while running. Utility Model Content

[0005] In order to overcome the problem that the existing treadmill handle structure has a single function and is unable to assist users in arm rehabilitation training.

[0006] The technical solution of the utility model is: a treadmill that can be used for rehabilitation exercise, comprising a treadmill body, a handle, a connecting sleeve, a top platform body, a folding cavity, a rotating shaft connecting piece and a handle; handles are installed on the left and right sides of the frame of the treadmill body, a detachable connecting sleeve is installed on the handle, a positioning flange is provided on the handle to limit the rotation of the connecting sleeve, a top platform body is provided on the upper end of the connecting sleeve, a folding cavity for folding and storing the handle is opened on the surface of the top platform body, the handle has a U-shaped cross-section structure and the outer edges are all arc-chamfered, the rear surface of the handle is an inwardly concave buckle groove, one end of the handle is movably connected to the folding cavity through the rotating shaft connecting piece, and a torsion spring with a torque value of 20N-45N is provided in the rotating shaft connecting piece, and a cap is clamped and installed on the other end of the handle.

[0007] Preferably, when on the treadmill, the user flips the handle upward from the folding cavity and pulls it above the top platform, then firmly grasps the corresponding handle with both hands at the same time, and buckles the fingers backward into the buckle groove. The U-shaped structure formed by the handle and the buckle groove makes the user's grip more comfortable, and relative sliding between the hand and the handle is not likely to occur, and the grip is firm. When starting the treadmill, the user swings both hands synchronously, generating a reciprocating push-pull effect on the handle, and the handle is rotated back and forth through the rotating shaft connector. When the handle is pushed forward, the handle resists the torsion of the torsion spring, which exercises the user's arm and facilitates the user's arm rehabilitation.

[0008] Preferably, the handlebars are hollow in structure and have a spiral heating resistance wire inside. The heating resistance wire is electrically connected to the treadmill power supply unit. The outer surface of the handlebars is covered with a silicone sleeve with a non-slip texture. When the treadmill is started, the heating resistance wire is powered at the same time and heat is transferred to the user's hands through the handlebars, which helps to promote smooth blood circulation in the user's arms. At the same time, the user's arm swinging exercise and lower limb running training will further enhance consumption and promote health.

[0009] Preferably, the grip is an integral grip rod, to which a No. 1 limiting ring and a No. 2 limiting ring are fixedly connected, a positioning flange is arranged on the upper surface of the integral grip rod and the positioning flange is between the No. 1 limiting ring and the No. 2 limiting ring, and the No. 1 limiting ring and the No. 2 limiting ring respectively abut against both sides of the connecting sleeve, so that the connecting sleeve cannot move axially on the integral grip rod, thereby keeping the user's hand stable.

[0010] Preferably, the connecting sleeve includes a clamp and an ear plate; the clamp is a ring-shaped structure with an opening at the lower edge and is clamped on the integral grip rod. Ear plates are provided on both sides of the opening of the clamp, and the two ear plates are fastened to each other by bolts. The lower edge opening of the clamp is aligned with the integral grip rod and pressed down, and the integral grip rod is squeezed into the clamp from the opening. The clamp and the integral grip rod are clamped together, and then the bolts are screwed into the holes on the ear plates to fix them, thereby completely fixing the clamp to the integral grip rod.

[0011] Preferably, the grip includes a one-section split grip, a two-section split grip and a screw ring, a one-section split grip is provided with a screw ring at one end, a two-section split grip is provided with a screw mouth at one end, the one-section split grip is fixed to the two-section split grip by a threaded connection between the screw ring and the screw mouth, a No. 1 limiting ring is fixedly connected to the one-section split grip, the No. 2 limiting ring is fixedly connected to the two-section split grip, and a positioning flange is provided between the No. 1 limiting ring and the No. 2 limiting ring. Before installing the connecting sleeve, the threaded connection structure between the one-section split grip and the two-section split grip is disconnected, and then the connecting sleeve is installed on the two-section split grip. When the connecting sleeve needs to be removed, the one-section split grip and the two-section split grip must be disconnected first and then the connecting sleeve is removed.

[0012] Preferably, the connecting sleeve is a ring, which is a ring-shaped structure with regular edges and is mounted on the two-section split grip. The No. 1 limiting ring and the No. 2 limiting ring respectively abut against both sides of the ring and restrict its movement along the grip, fixing the one-section split grip and the two-section split grip together, so that the No. 1 limiting ring and the No. 2 limiting ring respectively abut against both sides of the ring, so that the ring cannot move axially on the two-section split grip, keeping the user's hand stable when the user holds the grip.

[0013] Preferably, a groove with an arc-shaped cross-section that matches the positioning flange is provided on the inner wall of the connecting sleeve. The positioning flange is embedded in the groove and limits the rotation of the connecting sleeve. After the connecting sleeve and the handle are installed, the positioning flange is embedded in the groove. At this time, the connecting sleeve can no longer rotate along the surface of the handle, so that the handle always remains in an upward position.

[0014] Beneficial effects of the utility model:

[0015] 1. By arranging an assembled connecting sleeve and a rotatable handle mounted on the connecting sleeve on the existing treadmill handle, and using a torsion spring with appropriate torsion force, the user can exercise his arms while running by swinging his arms and rotating the handle to overcome the torsion force of the torsion spring, thereby facilitating arm rehabilitation for the user.

[0016] 2. The handle can be hidden in the folding cavity when not in use. There is no large protrusion on the entire grip structure, which is more beautiful overall.

[0017] 3. The heating resistance wire in the handle can heat the handle, which helps promote blood circulation in the user's hands and speed up body metabolism when the user holds it. BRIEF DESCRIPTION OF THE DRAWINGS
