The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, but medical water jet mainly formed by the medical pump module 3 that double cam module 1, push rod module 2 and automatic trip of the present utility model close, close mechanism and medical pump main body 17 but the medical pump module 3 that automatic trip closes is divided into again automatic trip.Automatic trip closes mechanism mainly for separating of the push rod module 2 of medical pump main body and power transmission, the automatic trip of realizing medical pump from.
With reference to Fig. 1 and Fig. 3.In this utility model, the automatic trip of new medical water cutter closes mechanism, comprises 1 cover nut screw drive mechanism, 2 clutch blocks, 2 U-shaped elastic collars, medical pump up and down two decks, 2 bracing frames, 1 base.Automatic trip closes mechanism and separates the connection that medical pump plunger 6 is connected with clutch block by the nut screw drive mechanism, simultaneously, backs down the upper and lower deck 18 of medical pump, reaches the purpose that breaks away from medical pump main body 17.
With reference to Fig. 2 and Fig. 3.Clutch block 7 is connected by U-shaped elastic collar 8 with medical pump plunger 6, realizes that module 1 is to the transmission of power of medical pump.Motor drives nut 14 by belt and rotates, and the rotation of nut 14 is converted into the rectilinear motion of leading screw 15, takes off to close pushing block 13 and be fixedly connected with leading screw, and leading screw 15 closes pushing block 16 and is connected in good time with taking off,
With reference to Fig. 4.Pump housing bracing frame 20 lower ends are fixed on the base 21, and medical pump main body 17 is supported in the upper end, and cylinder body leading screw bracing frame 5 lower ends are fixed on the base 21, and U-shaped guiding geosynclinal block 12 is fixed on the cylinder body leading screw bracing frame 5.
With reference to Fig. 4 and Fig. 6.Spring 24 passes square opening 22 and connects deck 19 under medical pump upper blocking seat 18 and the medical pump, and deck 19 is provided with voussoir 25 under medical pump upper blocking seat 18 and the medical pump.Spring 24 adopts extension springs, and original state makes deck 19 closures under medical pump upper blocking seat 18 and the medical pump by self elastic force, clamps medical pump main body 17, prevents that medical pump main body 17 from jumping back and forth, guarantees the medical pump normal operation.
With reference to Fig. 3.Medical pump cylinder body 23 1 ends are supported by cylinder body retainer 4, and the other end is supported by cylinder body leading screw bracing frame 5, and two end supports helps to prevent 23 distortion of medical pump cylinder body, guarantee that plunger 6 at the ride comfort of medical pump cylinder body 23 inner carriers motion, reduces frictional resistance.
With reference to Fig. 4, Fig. 5, Fig. 6.Nut 14 links to each other with cylinder body retainer 4 and cylinder body leading screw bracing frame 5 by bearing respectively, and enough nut length can guarantee the stability of leading screw 15 operations.Leading screw 15 front ends close pushing block 13 and are fixedly connected with taking off, leading screw 15 is terminal to be closed push rod 16 and is fixedly connected with taking off, motor is connected to the belt wheel of nut 14 outer rings by Timing Belt, motor rotarily drives leading screw 15 and does rectilinear motion, taking off to close has a projection below the pushing block 13, and projection is goed deep into U-shaped guide card geosynclinal block 12, and restriction is taken off and closed pushing block 13 and follow leading screw 15 and rotate together, guarantee that leading screw 15 only has rectilinear motion, prevent its rotation.Require double cam mechanism urges plunger 6 and plunger 11 must move to the same level position this moment, when driving, takes off when closing pushing block 13 and moving to the position of clutch block 7 and clutch block 10 by leading screw 15, take off and close pushing block 13 and strut simultaneously U-shaped elastic collar 8 and U-shaped elastic collar 9, clutch block 7 separates with plunger 11 with plunger 6 respectively with clutch block 10, synchronization, leading screw 15 drives to take off and closes the position that push rod 16 moves to the voussoir 25 of deck 19 under medical pump upper blocking seat 18 and the medical pump, outstanding voussoir 25 is conducive to take off on the one hand and closes push rod 16 and touch the medical pump deck, help on the other hand to decompose thrust perpendicular to deck 19 under medical pump upper blocking seat 18 and the medical pump with taking off the horizontal thrust of closing push rod 16, thereby the elastic force that can overcome spring 24 struts deck 19 under medical pump upper blocking seat 18 and the medical pump, medical pump main body 17 just can be taken out together with cylinder body 23, the automatic trip of finishing medical pump and medical water jet from.
It is to strut simultaneously deck 19 under U-shaped elastic collar 8, U-shaped elastic collar 9 and medical pump upper blocking seat 18 and the medical pump that automatic trip closes the mechanism design requirement, if wherein there is one to fail to strut on request, then medical pump main body 17 can not be taken out.If double cam mechanism does not promote plunger 6 on request and plunger 11 arrives the same level position, but tandem state, then take off and close pushing block 13 and can only strut one of them clutch block in arbitrary position, another clutch block is one of them plunger of locking tightly just, medical pump just can not take out so, also just can not realize the disengaging of medical pump and medical water jet.
