Technical Field
[0001] The utility model relates to the technical field of limb exercise, in particular to a limb exerciser. Background Art
[0002] Neurology is a secondary discipline concerning neurology and does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases (cerebral infarction, cerebral hemorrhage), migraine, brain inflammatory diseases (encephalitis, meningitis), myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy and myasthenia gravis, etc. In order to enable patients in the Department of Neurology to recover better, limb exercisers are needed to exercise the patient's hand strength.
[0003] Traditional limb exercisers mostly use hand grippers to exercise the patient's hand strength, but the elastic strength of this equipment is fixed, and it is not convenient to control the elastic strength according to the patient's needs. As a result, the patient's limb exercise effect may be affected due to the excessive or insufficient elasticity of the hand gripper. For this reason, we propose a limb exerciser. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a limb exerciser, including a mounting box 1, both sides of which are fixedly connected with side rods 2, two groups of side rods 2 are used to support the mounting box 1, and limiting grooves 3 are opened on the side walls of the side rods 2. An elastic force adjustment component 4 is arranged inside the mounting box 1, and the elastic force adjustment component 4 is used to adjust the elastic force of the reset spring 43, so as to avoid the elastic force of the reset spring 43 being too large or too small, affecting the exercise effect on the limbs. The elastic force adjustment component 4 includes a first slide plate 41 and a second slide plate 42. The first slide plate 41 and the second slide plate 42 are both slidably connected to the inner wall of the installation box 1. The first slide plate 41 and the second slide plate 42 are elastically connected by a return spring 43. The return spring 43 is used to connect the first slide plate 41 and the second slide plate 42 together. The bottom surface of the first slide plate 41 is fixedly connected with a connecting plate 44. The connecting plate 44 passes through and is slidably connected to the bottom surface of the installation box 1. The bottom end of the connecting plate 44 is fixedly connected with a C-shaped plate 45. The notch of the C-shaped plate 45 is fixedly connected with a buckle plate 46. The buckle plate 46 is provided to facilitate finger buckling, thereby pulling the C-shaped plate 45 downward, so that the connecting plate 44 drives the first slide plate 41 to move synchronously, so that the return spring 43 is stretched, thereby achieving the effect of exercising the patient's hand strength.
[0023] Reference Figure 1-Figure 3 The C-shaped plate 45 is fixedly connected to both sides with a limit block 47, which is slidably connected to the inside of the limit slot 3. The limit block 47 cooperates with the limit slot 3 to make the C-shaped plate 45 more stable during movement, and the limit block 47 can only slide within the range of the limit slot 3, thereby limiting the range of movement of the C-shaped plate 45. The surface of the second slide plate 42 is rotatably connected to a screw rod 48, which penetrates and is rotatably connected to the top of the installation box 1. The top of the screw rod 48 is fixedly connected to a brake wheel 49. By rotating the brake wheel 49, the screw rod 48 is rotated forward or reversely, thereby driving the second slide plate 42 to rise or fall, thereby controlling the stretching length of the return spring 43, and achieving the effect of adjusting the elastic force of the return spring 43.
[0024] Reference Figure 1 and Figure 3-Figure 4The bottom end of the side rod 2 is fixedly connected with a threaded rod 5, and the outer wall of the threaded rod 5 is provided with a height adjustment assembly 6, which is used to control the distance between the grip rod 64 and the buckle plate 46, so that it can be adjusted according to the size of the patient's hand, thereby improving applicability. The height adjustment assembly 6 includes a threaded sleeve 61, which is threadedly connected to the outer wall of the threaded rod 5, and the threaded sleeve 61 is used to be threadedly connected to the threaded rod 5, and the threaded sleeve 61 is rotated to rise or fall along the threaded rod 5. An annular groove 62 is provided on the outer wall of the threaded sleeve 61, and a ring 63 is rotatably connected to the outer wall of the annular groove 62. A grip rod 64 is fixedly connected between the two groups of rings 63, and the ring 63 is limited by the annular groove 62, so that the ring 63 and the threaded sleeve 61 move synchronously, and the ring 63 is sleeved outside the annular groove 62 and is rotatably connected to the annular groove 62. When the threaded sleeve 61 rotates, the ring 63 will not rotate, thereby controlling the distance between the grip rod 64 and the buckle plate 46.
[0025] Working principle:
[0026] When in use, the screw rod 48 is rotated forward or reversely by rotating the brake wheel 49, thereby driving the second slide plate 42 to rise or fall, thereby controlling the stretching length of the reset spring 43, and achieving the effect of adjusting the elastic force of the reset spring 43. The C-shaped plate 45 is pulled downward by holding the pinch plate 46 with fingers, so that the connecting plate 44 drives the first slide plate 41 to move synchronously, so that the reset spring 43 is stretched, thereby achieving the effect of exercising the patient's hand strength. The C-shaped plate 45 is more stable during the movement process through the cooperation between the limit block 47 and the limit groove 3. The threaded sleeve 61 can be raised or lowered along the threaded rod 5 by rotating the threaded sleeve 61. The annular groove 62 limits the ring 63, so that the ring 63 and the threaded sleeve 61 move synchronously, thereby controlling the distance between the grip 64 and the pinch plate 46.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
