Background technology
At present, arm fracture patient is in the process of rehabilitation, in order to recover as early as possible the function of arm muscle, avoiding occurring the atrophy of arm muscle, conventionally all need arm muscle massage or train, is to be all athletic for normal person the latter due to existing muscular training apparatus, its intensity and dynamics are all excessive for arm fracture patient, and the mode effect of massage has not too obviously, so be unfavorable for the rehabilitation of arm fracture patient, be especially unfavorable for the rehabilitation of arm muscle.
Summary of the invention
Problem to be solved in the utility model is: a kind of simple in structure, training dynamics is less and training dynamics is adjustable arm fracture patient rehabilitation apparatus for training is provided.
In order to solve the problems of the technologies described above, arm fracture patient rehabilitation apparatus for training of the present utility model, comprise riser, described riser is provided with rotating shaft, in described rotating shaft, be fixed with a cam, on the riser of described cam top, be fixed with a sleeve, in described rotating shaft, be also fixed with the crank that a drive shaft is rotated, the outward flange of described cam is provided with a circle cam path, in described sleeve, be inserted with a push rod, described push rod stretches out on sleeve, the bottom of described push rod is provided with a roller, described roller is inserted in cam path, described roller and cam path match, the top of described push rod is provided with as external screw thread, the top of described push rod is socketed with an adjusting nut, between described adjusting nut and push rod for being threaded, between described adjusting nut and sleeve, be provided with an extension spring, one end of described extension spring is connected with sleeve, one end is connected with adjusting nut in addition, the below of described riser is provided with a fixture.
For convenient, riser is fixed, arm fracture patient rehabilitation apparatus for training of the present utility model, described fixture comprises the U-shaped plate that is fixed on riser below, in described U-shaped plate, is inserted with tight fixed bolt, between described tight fixed bolt and U-shaped plate for being threaded.
For rotating shaft can be rotated smoothly, arm fracture patient rehabilitation apparatus for training of the present utility model, described riser is provided with bearing, and described rotating shaft is inserted with in bearing.
The beneficial effect that the utility model is obtained is: (1) is simple in structure, (2) outward flange of cam is provided with a circle cam path, in cam path, be provided with roller, roller is arranged on push rod, the top of push rod is provided with adjusting nut, push rod is inserted in sleeve, between sleeve and adjusting nut, be connected with extension spring, thereby when actuated by cams push rod moves up and down, variation along with angular displacement of the cam, the height of push rod can change thereupon, the stressed of extension spring also changes thereupon, because cam is to be driven by rotating shaft under the effect of the driving force of crank, so the driving force of crank also changes along with the difference of cam angle, because the distance between the outer rim of cam and the centre of gyration of cam is continually varying, thereby the size of the driving force of crank is also continually varying, difference along with angular displacement of the cam, ascending the gradually changing or descending gradually changing of driving force of crank, because crank is to be driven by the muscles of the arm of patient, also just make patient's arm muscle tighten by being relaxed to, lax by being tightened to again, thereby reach good training effect, (3) by changing the position of adjusting nut on push rod, just can regulate the length between sleeve and adjusting nut of coil tension spring, also just can change the scope of the pulling force of extension spring in training process, and finally change the scope of the driving force of crank, to be more applicable to different patients, train, very convenient, (4) riser is provided with bearing, and described rotating shaft is inserted with in bearing, thereby can make rotating shaft more smooth and easy when rotating.

In figure: 1, tight fixed bolt, 2, U-shaped plate, 3, crank, 4, rotating shaft, 5, cam, 6, cam path, 7, roller, 8, push rod, 9, sleeve, 10, extension spring, 11, adjusting nut, 12, external screw thread, 13, riser, 14, bearing.
The specific embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, arm fracture patient rehabilitation apparatus for training of the present utility model, comprise riser 13, described riser 13 is provided with rotating shaft 4, in described rotating shaft 4, be fixed with a cam 5, on the riser 13 of described cam 5 tops, be fixed with a sleeve 9, in described rotating shaft 4, be also fixed with the crank 3 that a drive shaft 4 is rotated, the outward flange of described cam 5 is provided with a circle cam path 6, in described sleeve 9, be inserted with a push rod 8, described push rod 8 stretches out on sleeve 9, the bottom of described push rod 8 is provided with a roller 7, described roller 7 is inserted in cam path 6, described roller 7 matches with cam path 6, the top of described push rod 8 is provided with as external screw thread 12, the top of described push rod 8 is socketed with an adjusting nut 11, between described adjusting nut 11 and push rod 8 for being threaded, between described adjusting nut 11 and sleeve 9, be provided with an extension spring 10, one end of described extension spring 10 is connected with sleeve 9, one end is connected with adjusting nut 11 in addition, the below of described riser 13 is provided with a fixture, described fixture comprises the U-shaped plate 2 that is fixed on riser 13 belows, in described U-shaped plate 2, is inserted with tight fixed bolt 1, between described tight fixed bolt 1 and U-shaped plate 2 for being threaded, described riser 13 is provided with bearing 14, and described rotating shaft 4 is inserted with in bearing 14.
Arm fracture patient rehabilitation apparatus for training of the present utility model, when patient carries out rehabilitation training, first pass through fixture, namely tight fixed bolt 1 and U-shaped plate 2 are by riser 13 fixed bed boards or desktop, then by patient, with arm-shaking crank 3, rotated, under the drive of crank 3, rotating shaft 4 and cam 5 just start to rotate, cam 5 is when rotating, will drive push rod 8 to move up and down along sleeve 9, the outward flange of cam 5 is provided with a circle cam path 6, in cam path 6, be provided with roller 7, roller 7 is arranged on push rod 8, the top of push rod 8 is provided with adjusting nut 11, push rod 8 is inserted in sleeve 9, between sleeve 9 and adjusting nut 11, be connected with extension spring 10, thereby when cam 5 drives push rod 8 to move up and down, variation along with cam 8 rotational angles, the height of push rod 8 can change thereupon, the stressed of extension spring 10 also changes thereupon, because cam 5 is to be driven and rotated by rotating shaft 4 under the effect of the driving force of crank 3, so the driving force of crank 3 also changes along with the difference of cam 5 corners, because the distance between the outer rim of cam 5 and the centre of gyration of cam 5 is continually varying, thereby the size of the driving force of crank 3 is also continually varying, difference along with cam 5 rotational angles, ascending the gradually changing or descending gradually changing of driving force of crank 3, because crank 3 is to be driven by the muscles of the arm of patient, also just make patient's arm muscle tighten by being relaxed to, lax by being tightened to again, thereby reach good training effect.
