Description
Technical field
This utility model relates to for the medical product syringe pump, and be used for clamping syringe and push away handle, be the clamping thrust unit that a kind of syringe pushes away handle.
Background technology
Several clamping device structures are arranged in the market, mainly can be divided into two big classes, a class is movable clamping device structure, and a class is fixed clamping device structure.Existing movable clamping device must be pinned shifting block with hands always in clamping syringe process, to open claw, throw off internal mechanism simultaneously and be used for pull handle back and forth, handle is adjusted to unclamped hands behind the position that needs and finish clamping, as loosing one's grip accidentally or slippage midway, the claw closure that resets immediately, and the clamping device structure is pinned and can not be moved, installation can not be finished, shifting block clamping again need be pinned.Fixed clamping device is in the mounting of syringe process, must take syringe on the other hand, mobile clamping device is to suitable position on the other hand, then syringe is placed in the clamping device and blocks, compress syringe jacket with briquetting device at last and finish installation process, its major defect is to operate simultaneously by two handss, and clamping device is fixing not movable, so if just be inconvenient to install clamping device after earlier syringe being fixed on shell.
The utility model content
The purpose of this utility model is to provide a kind of flexible operation, need not the reuse hands pushes down the movable of handle shifting block (syringe) clamping thrust unit always.
For solving the problems of the technologies described above, this utility model syringe clamping thrust unit comprises protecgulum and back cover, and described protecgulum and described back cover are interconnected to form an accommodation space; Draw-in bar, described draw-in bar are arranged in described protecgulum and described back cover; Left side latch wheel and right latch wheel, described left latch wheel and described right latch wheel are arranged in the described accommodation space; Driving wheel, described driving wheel are arranged on the described draw-in bar, and described driving wheel connects the described left latch wheel of drive and described right latch wheel by gear; Left jamming claw and right jamming claw, described left jamming claw and described right jamming claw are arranged on the outside of described protecgulum, and described left jamming claw and described right jamming claw are connected with described left latch wheel and described right latch wheel; Rotate plectrum, described rotation plectrum is arranged on the described draw-in bar; Shifting block, described shifting block are arranged on the described back cover, can slide in the chute of back cover; Shifting block is rigidly connected with rotating plectrum, external force is delivered to rotates plectrum as clamping thrust unit driving force.
Contact, described contact is arranged between described protecgulum and the described back cover, pass and rotate the plectrum through hole, the through hole that rotates on the plectrum has two sections of big small-bores, in like manner contact also is designed to different two sections of diameter, contact realizes rotating the locking of plectrum diverse location at diverse location, and then realizes left and right sides claw opening and closing state.Spring, contact one end is equipped with the compression spring, realizes that contact ejects action under no occlusion state.
This utility model syringe clamping thrust unit makes syringe clamping when different injection volumes that different model is installed more convenient, and is reliable.

The specific embodiment
Below in conjunction with accompanying drawing this utility model syringe clamping thrust unit is described in further detail.
As shown in Figure 1 and Figure 2, this utility model syringe clamping thrust unit comprises protecgulum 1 and back cover 2, and protecgulum 1 and back cover 2 are interconnected to form an accommodation space; Draw-in bar 17, draw-in bar 17 are arranged in protecgulum 1 and back cover 2; Left side latch wheel 4 and right latch wheel 5, left latch wheel 4 and right latch wheel 5 are arranged in the accommodation space; Driving wheel 6, driving wheel 6 are arranged on the draw-in bar 17, and driving wheel 6 drives left latch wheel 4 and right latch wheel 5; Left jamming claw 8 and right jamming claw 9, left jamming claw 8 and right jamming claw 9 are arranged on the outside of protecgulum 1, and left jamming claw 8 and right jamming claw 9 are connected with left latch wheel 4 and right latch wheel 5; Rotate plectrum 10, rotate plectrum 10 and be arranged on the draw-in bar 17; Shifting block, described shifting block are arranged on the described back cover 2, can slide in the chute of back cover 2; Shifting block 11 is rigidly connected with rotating plectrum 10, and hands is pressed shifting block 10, drives to rotate plectrum 11, drives internal gear and claw and rotates.
This utility model syringe clamping thrust unit is installed on the injection base 15, also is provided with syringe briquetting 16 in its outside.
Original state, claw is in closure state, press shifting block 11 during mounting of syringe, driving rotation plectrum 10 rotates together, drive left jamming claw 8 and right jamming claw 9 and open, contact 12 unclamps hands ejecting to protecgulum 1 under the effect of spring 14, and contact 12 enlarged diameter sections are stuck in rotation plectrum macropore section place, namely rotate plectrum 10 and be lockable, left jamming claw 8 and right jamming claw 9 also are lockable at open configuration; The syringe that medicinal liquid is housed is fixed on the shell, pull handle, contact 12 are run into syringe and are pushed away handle 3, and contact 12 is thrown off from rotatable lamella 10 macropores, rotate plectrum 10 releases, rotate plectrum 10 revolutions under 13 effects of second torsion spring, be returned to original state, contact 12 slips into rotatable lamella 10 aperture section, be locked in the fore shell mean place, left jamming claw 8 right jamming claws 9 also turn round, and turn to can effectively block the different size syringe and push away handle 3 positions, finish syringe and install.After injection is finished, pressing shifting block 11 shrinks back, drive and rotate plectrum 10 rotations, when rotation plectrum 10 macropore sections overlapped with contact 12 enlarged diameter sections, contact ejected under spring 14 acts on, after syringe is pushed away handle 3 and effectively is separated from handle, unclamp shifting block 11, namely rotate plectrum 10 and pinned by contact 12, left and right sides claw pins automatically, and internal structure is also thrown off can free easily pull handle.
Simplified summary is that this utility model syringe clamping thrust unit has a scalable contact, and contact is run into syringe and will be triggered shifting block by hands and reset, and movable claw is brought together into needs the position, finishes installation process.After injection is finished, press shifting block and shrink back, then pin claw after openhanded the opening automatically, can freely spur clamping device.This utility model handle makes syringe clamping when different injection volumes that different model is installed more convenient, and is reliable.
