Fig. 2 is the decomposition diagram that illustrates according to pumping part of the present invention.Fig. 3 is the perspective view that illustrates according to the rear structure of locking component of the present invention.Fig. 4 is the sectional view that the assembly structure of the pumping part that the IV-IV line in Fig. 2 cuts open is shown.

At first, plunger unit 52 is placed in the cylinder, and its modes of emplacement flexibly supports for making its spring 51 that is reset, so that its reciprocating motion, and its front end is connected with the rear portion of trigger 80.Base for post unit 52 is by forming with lower component: piston component 52a, and the spring 51 of being reset supports, and wherein, piston component 52a is in the state reciprocating motion down near the inwall of cylinder 65; Piston supports member 52d is installed in the leading section of piston component 52a; And has highlightedly a lock rib 52g that forms on its outer surface; Wherein, when the front end of piston supports member 52d suitably during contact trigger 80, piston supports member 52d allows piston component 52a to be connected to trigger.

Piston component 52a forms step combining unit 52b at its front end.The mode that step combining unit 52b is reduced according to its diameter (that is, tapered mode) forms, and its outer surface is formed with banded engagement groove 52c.The rear end of piston supports member 52d is installed on the step combining unit 52b.Piston supports member 52d is made up of cylinder combining unit 52e, and the inwall of cylinder combining unit 52e is formed with and is formed banded combination projection 52f to combine accordingly with engagement groove 52c.Here, engagement groove 52c is cut into semicircle shape with respect to its cross section, protrude out the semicircle shape that becomes corresponding with engagement groove 52c in conjunction with projection 52f, thereby the two can be assembled together.That is to say; When the cylinder combining unit 52e that is assembled to piston supports member 52d as the step combining unit 52b of piston component 52a goes up; Be installed on the engagement groove 52c in conjunction with projection 52f with being forced; Thereby piston supports member 52d and piston component 52a are by assembling integratedly, to form plunger unit 52.

In addition, in an embodiment of the present invention, lock rib 52g forms a pair of of symmetry.Lock rib 52g is formed on the relative sidepiece of outer surface of the front end of piston supports member 52d with 180 degree, so that they can be positioned at the front end of plunger unit 52.Therefore, plunger unit 52 can be by locking equably.

And locking component 53 is installed to the open end of cylinder 65 pivotally, and has through hole 53a, that is, locking component 53 forms ring, passes with the front end that allows plunger unit 52.Locking component 53 longitudinally forms sliding recess 53b on the interior week of through hole 53a, to allow lock rib 52g motion.In addition, locking component 53 forms the latch recess 53c relevant with sliding recess 53b on the interior week of front end, and wherein, each latch recess 53c forms step along circumferencial direction.In an embodiment of the present invention, sliding recess 53b and latch recess 53c also form a pair of, and place respectively on the opposite side of inner periphery of locking component 53, with corresponding with the position of lock rib 52g.Locking component 53 is formed with the handle 54 that allows locking component 53 rotations, so that lock rib 52g and sliding recess 53b can be in alignment with each other or not line up each other under trigger 80 proal states.In an embodiment of the present invention, handle 54 is embodied as highlightedly and is formed on the outer surface of locking component 53.Therefore, when the user utilizes handle 54 that locking component 53 is rotated to an angle so that lock rib 52g is when aliging with latch recess 53c, plunger unit 52 is restricted.On the contrary, when lock rib 52g alignd with sliding recess 53b, plunger unit 52 can be operated.

In addition, handle 54 has adhesion protrusion 55, and this adhesion protrusion 55 forms highlightedly, and when it rotates with locking component integratedly, and adhesion protrusion 55 closely adheres on the outer wall of open end of cylinder 65.Therefore, if user's grasps handle 54 is rotated it then, then locking component 53 only allows its operation.

In an embodiment of the present invention, locking component 53, handle 54 and adhesion protrusion 55 are processed by synthetic resin, and form through injection molding.But they can be made assembling then individually.

Be to according to the operation of injector device of the present invention and the description of effect below.

Referring to figs. 1 through Fig. 5, through under the back-moving spring 51 proal states, when the latch recess 53c that is positioned at locking component 53 as the lock rib 52g of plunger unit 52 went up, plunger unit 52 remained on lock-out state with trigger 80 in trigger 80 and plunger unit 52.Here, because the adhesion protrusion 55 of handle 54 closely adhered on the outer wall of cylinder 65, so upper plug unit 52 also keeps their lock-out state with trigger 80 even external force is applied to them.In this state, though the user tries to spur trigger 80, plunger unit 52 can not moved owing to locking component 53 backward.

On the contrary, like Fig. 6 and shown in Figure 7, when user's grasps handle 54 and spin locking member 53 made that lock rib 52g is held (with reference to the direction of arrow among Fig. 7) by sliding recess 53b, trigger 80 was unlocked with plunger unit 52.Here, locking component 53 lock-out state can be only along a direction (with reference to the direction of arrow among Fig. 7) rotation, this is because latch recess 53c forms step, makes them hold lock rib 52g and communicates with sliding recess 53b.

Like this, during the grip of the drop-down trigger action 80 of state that is unlocked at trigger 80 and plunger as the user, back-moving spring 51 is extruded and plunger unit 52 enters into the inside of cylinder 65.Simultaneously, the lock rib 52g of plunger unit 52 moves through the sliding recess 53b of locking component 53.Therefore, the liquid that is filled in the cylinder 65 is opened second check-valves 63, flows through discharge-channel 61 then, thereby is ejected through nozzle 70.Simultaneously, because first check-valves 43 has cut out flow channel 41, so the liquid in the cylinder 65 is only transferred in the nozzle 70.

On the other hand, when the user discharged grip 82, plunger unit 52 was outstanding once more owing to the restoring force of back-moving spring 51, and simultaneously, grip 82 is positioned at its original state, and the inside of cylinder 65 becomes vacuum pressure condition.Therefore because the pressure reduction between the inside of the inside of cylinder 65 and container 10, so first check-valves 43 be raised, thereby open flow channel 41.Therefore, the liquid in the container is inhaled into the inside of cylinder 65 through inflow pipe 44.Simultaneously, make second check-valves 63 close discharge-channel 61, so liquid is not revealed owing to exert pressure.In addition, when the liquid of specified quantitative is aspirated from container, enter into container through negative pressure through-hole 64, make injector device 30 keep its original states with the corresponding extraneous air of amount of the liquid that is aspirated.

After using injector device 30, when user's grasps handle 54 then along rightabout spin locking member 53 so that lock rib 52g is when being arranged in latch recess 53c (with reference to Fig. 5), trigger 80 enters into lock-out state once more with plunger unit 52.

That is to say, when handle 54 along released state (with reference to the direction of arrow among Fig. 5) when being rotated down, plunger unit 52 enters into lock-out state through locking component 53.Therefore, trigger 80 can not be unlocked up to plunger unit 52 by operation.Therefore, the child can not by mistake operate injector device 30.Owing to closely adhered in the adhesion protrusion on the handle 54 55 on the outer wall of open end of cylinder 65, so only otherwise applying external force plunger unit 52 just keeps its lock-out state.

And, because the front end of plunger unit 52 is accommodated among the through hole 53a of locking component 53, so when injector is wrapped, loads and carries, also can be out of shape even exert pressure from two ends and receive when impacting plunger unit 52 when trigger.

Though described the preferred embodiments of the present invention from schematic purpose, it should be appreciated by those skilled in the art, under the situation that does not break away from disclosed scope of the present invention of claim and spirit, can carry out various modifications, increase and replacement.
