Description
Technical field
The present invention relates to medical instruments field, be specifically related to automatically take off locking device.
Background technology
The domestic starting of the development to medical water jet is late, also exist a lot of not enough, the instability of water cutter pressure, control system is more complicated, replacing with particularly at medical pump, waste time and energy, because the quick-replaceable of medical pump, requirement that is disposable and asepticize are higher, but because medical water jet is applied to clinical, how the disposable apparatus of medical pump carries out the connection after departing from and changing, well can have solution, this all has a great impact with regard to tool doctor or patient always.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, easy to use, automatically de-conjunction can be realized, and the automatically de-locking device be swift in motion.
The present invention is de-locking device automatically, comprise synchronizing wheel and leading screw, described synchronizing wheel center is provided with a tapped through hole, described leading screw matches with this tapped through hole, one end that leading screw stretches out synchronizing wheel is socketed with one and de-ly closes pushing block, the boss of the described synchronizing wheel left and right sides is connected with a bracing frame and retainer by bearing, described retainer center is provided with a stepped hole, a T-shaped de-conjunction push rod is provided with in described stepped hole, montant on described de-conjunction push rod is a hollow bar, described leading screw is arranged in this hollow bar, the cross bar of described de-conjunction push rod, passing through of retainer is upper, lower cover connects, on described, lower cover is connected by spring, on, a medical pump valve body is also provided with between being somebody's turn to do down, described synchronizing wheel is connected with Timing Belt.
Preferably, upper and lower cover is provided with wedge.
Preferably, the model of the bearing on bracing frame is 6902.
Preferably, the model of the bearing on retainer is 61804.
Structure of the present invention is simple, easy to use, can realize automatically de-conjunction, and be swift in motion.
Accompanying drawing explanation
Fig. 1 is the structural representation automatically taking off locking device.
Reference numeral: 1-is de-closes pushing block, 2-bracing frame, the bearing on 3-bracing frame, 4-synchronizing wheel, 5-Timing Belt, the bearing on 6-retainer, 7-retainer, 8-leading screw, and 9-is de-closes push rod, 10-upper cover, 11-spring, 12-medical pump valve body, 13-lower cover.
Detailed description of the invention
The present invention is de-locking device automatically, comprise synchronizing wheel 4 and leading screw 8, described synchronizing wheel 4 center is provided with a tapped through hole, described leading screw 8 matches with this tapped through hole, one end that leading screw 8 stretches out synchronizing wheel 4 is socketed with one and de-ly closes pushing block 1, the boss of described synchronizing wheel 4 left and right sides is connected with a bracing frame 2 and retainer 7 by bearing, described retainer 7 center is provided with a stepped hole, a T-shaped de-conjunction push rod 9 is provided with in described stepped hole, montant on described de-conjunction push rod 9 is a hollow bar, described leading screw 8 is arranged in this hollow bar, the cross bar of described de-conjunction push rod 9, passing through of retainer 7 is upper, lower cover 10, 13 connect, on described, lower cover 10, 13 are connected by spring 11, on, lower cover 10, a medical pump valve body 12 is also provided with between 13, described synchronizing wheel 4 is connected with Timing Belt 5.Upper and lower cover 10,13 is provided with wedge.The model of the bearing 3 on bracing frame is 6902.The model of the bearing 6 on retainer is 61804.
Driven by motor Timing Belt 5 does gyration, and synchronizing wheel 4 does gyration with Timing Belt 5, by worm drive, the gyration of synchronizing wheel 4 is converted into the rectilinear motion of leading screw 8.The de-pushing block 1 that closes does rectilinear motion with leading screw 8, when leading screw 8 rear end round boss face with de-closes push rod 9 contact time, the front end now taking off conjunction pushing block 1 contacts just with the jump ring on actuating device fixture block.Then the de-push rod 9 that closes will with leading screw 8, de-conjunction pushing block 1 moving linearly.The de-pushing block 1 that closes contacts with the jump ring on actuating device fixture block and jump ring is opened, and the push rod of the plunger and drive system that complete disposable apparatus is separated; The de-push rod 9 that closes contacts with the voussoir in upper and lower covers and upper and lower covers is backed down by the pulling force overcoming spring 11.The disengaging of disposable apparatus (medical pump) is just completed through said process.Now replaceable disposable apparatus, finishes changing rear motor reversion, and the de-pushing block l that closes retreats with leading screw 8, and jump ring engages makes plunger again be connected with push rod, and upper and lower covers closes again due to the pulling force of spring 11.The replacing of medical water jet disposable apparatus is completed through said process.
