Utility model content
The purpose of this utility model is to provide a kind of angular turn mechanism based on joint extension apparatus, as one of critical piece of joint extension apparatus, mainly solve the angular adjustment problem of joint extension apparatus, make joint extension apparatus drive smoothly human synovial to carry out rehabilitation training.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Angular turn mechanism based on joint extension apparatus, comprises turning cylinder, is installed on this turning cylinder supporting with it axle sleeve, and the support arm that is flexibly connected with this axle sleeve of one end, with the handwheel rotating for controlling described turning cylinder being connected with described turning cylinder gear.
Further, the flexible handle for angle fine setting is installed on the other end of described support arm.
Again further, the center of described axle sleeve offers through hole, on this through hole, is provided with female thread, is provided with the supporting external screw thread of this female thread on the outer wall of described turning cylinder, and described turning cylinder, through the through hole of described axle sleeve, is threaded with it; Described support arm is flexibly connected with the end of described axle sleeve.
Further, described support arm comprises the horizontal segment that is connected with described axle sleeve, vertical section of flexible handle is installed, and this horizontal segment with vertically section between oblique section.
Preferably, for expand angle slewing area as far as possible, 90 ° of the angle а > between described horizontal segment and oblique section.
For convenient for production, described horizontal segment, vertically section and oblique section are structure as a whole.
Compared with prior art, the utlity model has following beneficial effect:
(1) this utility model principle is simple, by controlling the rotation of turning cylinder, axle sleeve is moved up and down on turning cylinder, thereby when driving support arm moving up and down, utilize the amplitude himself existing, make the arm support of joint extension apparatus do arcuate movement, to reach the object of the angle that changes arm support.
(2) this utility model is simple in structure, and whole angular turn mechanism is several parts only, by combining cleverly, just realized the object of angular adjustment, no matter be design, or produce, use, there is not advanced specification requirement, be applicable to very much ordinary populace and use.
(3) this utility model adopts the mode of screw thread transmission, has utilized the latching characteristics of screw thread transmission, and the unexpected injury that can effectively avoid maloperation to bring to human body, has good safety and reliability.
(4) this utility model can carry out wide-angle adjustment by handwheel, can also utilize flexible handle to carry out angle fine setting, effectively realizes the comprehensive adjusting of angle, both light, accurate again, can provide strong technical guarantee for joint extension apparatus.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the application schematic diagram of this utility model in the extension apparatus of joint.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
1-turning cylinder, 2-axle sleeve, 3-support arm, 4-handwheel, 5-flexible handle, 6-arm support.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the angular turn mechanism based on joint extension apparatus, mainly comprises turning cylinder 1, axle sleeve 2 and support arm 3.Wherein, on the outer wall of turning cylinder 1, be provided with external screw thread, the center of axle sleeve 2 offers through hole, and female thread is set in through hole, and turning cylinder 1 is through the through hole on axle sleeve, and both are threaded in realization.So, as long as power is provided, just axle sleeve 2 can move up and down along turning cylinder 1.On turning cylinder 1, be also provided with the handwheel 4 that gear connects with it, handwheel 4 is mainly used in controlling the open and close of turning cylinder, and controls the rotation number of turns of turning cylinder 1, controls the displacement of axle sleeve 2 on turning cylinder 1, realizes the control of large rotation angle.
Described support arm 3 one end are connected to the end of described axle sleeve 2, and both are flexibly connected, and make support arm can be subject to moving up and down of axle sleeve 2 and move up and down.And the other end of support arm is for being connected with the miscellaneous part of joint extension apparatus, for the miscellaneous part motion with movable joint extension apparatus.For the ease of support arm is carried out to angle fine setting, the other end at support arm is provided with flexible handle 5, this flexible handle can be controlled the link position of support arm and joint extension apparatus miscellaneous part, thereby reaches the object that regulates corner dimension between support arm and joint extension apparatus miscellaneous part.
In addition, in order to expand as much as possible angle slewing area, whole support arm is divided into three sections, be connected with axle sleeve 2 for horizontal segment, what flexible handle 5 was installed be vertical section, and is oblique section between horizontal segment is with vertical section.So design the shape of support arm, can convert simple the moving up and down of support arm to circular motion on vertical direction, thereby drive the miscellaneous part of the joint extension apparatus being attached thereto to carry out same circular motion, finally reach and make joint extension apparatus do the object that angle changes.In the present embodiment, it is 135 ° that the angle between horizontal segment and oblique section arranges а.
As shown in Figure 2, the application schematic diagram of the angular turn mechanism that this utility model provides in the extension apparatus of joint, from Fig. 2, can obviously find out, after turning cylinder 1 rotates, axle sleeve 2 will move up and down along turning cylinder 1, now, two support arms 3 will move up and down thereupon, and the arm support 6 being connected with support arm 3 will carry out circular motion, and the arm of human body is fixed on arm support, just can obtain suitable motion, i.e. the rehabilitation training in joint.Adjusting handle 4 can change the rotational angle of arm support in wide-angle; And adjusting flexible handle 5, can change the angle between support arm 3 and arm support 6, thereby realize regulate on low-angle, the cooperatively interacting of handwheel 4 and flexible handle 5, can perfect realize the angle of whole joint extension apparatus and control, guarantee safety and the effectiveness of joint rehabilitation training.
Above-described embodiment is only preferred embodiment of the present utility model; the not restriction to this utility model protection domain; in every case adopt design principle of the present utility model, and carry out non-creativeness work on this basis and the variation made, within all should belonging to protection domain of the present utility model.
