Abstract
The utility model relates to a kind of medical instrument exterior fixing rack angle demodulators, with revolute pedestal, the revolute pedestal upper end is hinged with adjusting screw, revolute pedestal lower end is hinged with revolute head, revolute head upper end is hinged with transmitting screw, the adjusting screw front end has internal thread hole, adjusting screw is cooperatively connected by the external screw thread of internal thread hole and transmitting screw pushes transmitting screw to move forward and backward, swinging up and down for revolute head is converted by the back-and-forth motion for transmitting screw rectilinear direction, to carry out angular adjustment to the exterior fixing rack being mounted on revolute head.The utility model is by adjusting screw and transmits the threaded connection transmission between screw, the linear motion for transmitting screw is changed into the rotary motion that revolute head is swung up and down, so as to carry out accurate, accurate angular adjustment to the medical instrument exterior fixing rack being mounted on revolute head, structure is simple, easy to adjust quick.
Description
Technical field
The utility model relates to a kind of medical instrument exterior fixing rack angle demodulators.
Background technique
The exterior fixing rack of many medical instruments not can be carried out angular adjustment, can not better adapt to the physiology of operative site
The structural stability of feature and biomethanics etc.；And many regulating mechanisms that can carry out angular adjustment, volume is larger, knot
Structure is complicated, can not stablize and accurately angle changing is adjusted, not applicable answering similar to this kind of precision instruments of medical instrument
With.
Summary of the invention
Technical problem to be solved by the utility model is: the utility model provides in order to overcome the deficiencies in the existing technology
A kind of medical instrument exterior fixing rack angle demodulator easy to adjust.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of medical instrument exterior fixing rack angle
Adjuster has revolute pedestal, and the revolute pedestal upper end is hinged with adjusting screw, and revolute pedestal lower end is hinged with
Revolute head, revolute head upper end are hinged with transmitting screw, and the adjusting screw front end has internal thread hole, and adjusting screw passes through
The external screw thread of internal thread hole and transmitting screw is cooperatively connected and transmitting screw is pushed to move forward and backward, and will transmit screw rectilinear direction
Back-and-forth motion be converted into swinging up and down for revolute head, to carry out angle to the exterior fixing rack that is mounted on revolute head
It adjusts.
Further, the adjusting screw is rotatablely connected by screw shaft and revolute pedestal, revolute head and rotation
It is rotatablely connected between secondary pedestal by revolute；The revolute head upper end is equipped with displacement transmission axle, transmitting screw and displacement
It is connected between transmission axle by pin rotation.
The beneficial effects of the utility model are: the utility model is by adjusting screw and transmits the threaded connection between screw
Transmission, the linear motion for transmitting screw is changed into the rotary motion that revolute head is swung up and down, so as to be mounted on revolve
Turn the medical instrument exterior fixing rack on secondary head and carry out accurate, accurate angular adjustment, structure is simple, easy to adjust quick.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic cross-sectional view of the utility model.
In figure: 1. revolute pedestal, 2. adjusting screw, 3. revolute head 4. transmits 5. screw shaft of screw, 6. revolute
7. being displaced 8. pin of transmission axle
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of medical instrument exterior fixing rack angle demodulator as shown in Figure 1 and Figure 2 has revolute pedestal 1, is located at
The upper left corner end of revolute pedestal 1 is hinged with adjusting screw 2 by screw shaft 5, and 1 bottom righthand side of revolute pedestal passes through revolute 6
It is rotatably connected to revolute head 3, the exterior fixing rack of medical instrument is connected on revolute head 3.
3 upper end of revolute head is equipped with displacement transmission axle 7, and displacement transmission axle 7 is rotatably connected to transmitting by pin 8
Screw 4,2 front end of adjusting screw have internal thread hole, the external screw thread that adjusting screw 2 passes through internal thread hole and transmitting screw 4
It is cooperatively connected and transmitting screw 4 is pushed to move forward and backward, and then revolute head 3 is pushed to swing up and down.
The utility model is by adjusting screw 2 and transmits the threaded connection transmission between screw 4, will transmit the straight of screw 4
Line movement is changed into the rotary motion that revolute head 3 is swung up and down, so as to the medical instrument being mounted on revolute head 3
Exterior fixing rack carries out accurate, accurate angular adjustment, and structure is simple, easy to adjust quick.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
