The screw is driven to rotate in a gear meshing mode, acceleration or torque increase can be realized by the aid of different configurations of a gear combination, use requirements of different syringes are met, and the gear type drive sliding table is simple in structure principle, low in manufacturing cost and fine in control effect.
Description
Technical field
This utility model relates to the actuation techniques of automated injection device, is specially a kind of for controlling the driving slide unit of syringe action.
Background technology
Drug injection is one for the treatment of means of commonly using clinically.Traditional manual injection length consuming time, waste of manpower, is difficult to control, and injection effect is not good.In order to address the above problem, there is on the market at present automatic injecting device, these drives structure of using of device mostly exist drive complicated, control weak effect, shortcoming that cost of manufacture is large.
Summary of the invention
For the problems referred to above, this utility model provides that a kind of structural principle is simple, cost of manufacture is little, control effective gear type drives slide unit.
This utility model for the technical scheme that its technical problem of solution adopts is:
The gear type being applied on automated injection device drives slide unit, comprising: base; Be fixed on the first fixed block and the second fixed block on base, the first fixed block and the second fixed block relative spacing arrange; Be arranged on the screw rod between the first fixed block and the second fixed block; Be fixed between the first fixed block and the second fixed block and the guide rod parallel with screw rod, guide rod surface smoothing; Be arranged on the drive motors on the first fixed block, the first gear is installed on the drive end of drive motors, screw rod is provided with the second gear in the end of the first fixed block one side, engages or directly engagement between the first gear and the second gear by gear train; Slide block, slide block is provided with the screw corresponding with screw rod and the guide hole corresponding with guide rod cross sectional shape, and slide block is installed on screw rod and guide rod by screw and guide hole respectively.
Preferably also comprise: the extension rod parallel with screw rod, on the first fixed block or the second fixed block, be provided with the via hole passing through for extension rod gap, one end of extension rod is fixed on slide block, and the other end extends to outside by via hole.
The beneficial effects of the utility model are: the mode that this utility model engages by gear drives screw rod rotation, can realize by the difference configuration to gear combination the effect of accelerating or increasing moment, are applicable to the user demand of different syringes; Its structural principle is simple, and cost of manufacture is low, controls effective.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of a kind of embodiment of this utility model;
Fig. 2 is the structural representation of the another kind of embodiment of this utility model.
The specific embodiment
This utility model is for automated injection device, specifically makes to produce displacement between the syringe cylindrical shell of syringe and syringe push rod, thereby realizes automatic injection function.
With reference to Fig. 1, gear type of the present utility model drives slide unit to be mainly made up of base 1, the first fixed block 2, the second fixed block 3, screw rod 4, guide rod 5, drive motors 6, the first gear 7, the second gear 8, slide block 9 etc.Shown in Fig. 1 is the basic structure that can realize this utility model function, and in the time of concrete application, the structure in figure can be carried out relevant configuration and optimization.
The first fixed block 2 and the second fixed block 3 are fixed on base 1, relative spacing setting between two fixed blocks.Screw rod 4 is installed between the first fixed block 2 and the second fixed block 3, and it can rotate.Guide rod 5 is fixed between two fixed blocks, parallel with screw rod 4, guide rod 5 surface smoothings, and the quantity of guide rod 5 can be 1, more than 2 or 2.Drive motors 6 is fixed on the first fixed block 2, rotates for drive screw 4.The first gear 7 is installed on the drive end of drive motors 6, screw rod 4 is provided with the second gear 8 in the end of the first fixed block 2 one sides, between the first gear 7 and the second gear 8, engage by gear train or directly engagement, in the present embodiment, the first gear 7 and the second gear 8 directly engage.Slide block 9 is provided with the screw corresponding with screw rod 4 and the guide hole corresponding with guide rod 5 cross sectional shapes, and slide block 9 is installed on screw rod 4 and guide rod 5 by screw and guide hole respectively.
As shown in Figure 1, when this utility model uses, two parts for fixing syringe cylindrical shell and push rod are located at respectively slide block 9 and fixed block, drive motors 6 drives screw rod 4 to rotate, and when screw rod 4 rotates, slide block 9 keeps not turning under the effect of guide rod, but is subjected to displacement, therefore between slide block and fixed block, there is relative displacement, syringe cylindrical shell and push rod produce relative displacement, when push rod to cylindrical shell near time, complete automatic injection process.
The first gear 7 between screw rod 4 and drive motors 6, the second gear 8 can be set as removable form, make the situation that can use according to reality carry out flexible combination to gear.When adopting pinion on screw rod 4, on drive motors 6, adopt gear wheel, the rotation of screw rod 4 can be accelerated so, and the injection speed of syringe is accelerated; When adopting gear wheel on screw rod 4, on drive motors 6, adopt gear wheel, the velocity of rotation of screw rod 4 reduces so, and motor can be realized high thrust injection under lower output torque.
Fig. 2 is the structural representation of the another kind of embodiment of this utility model.In the present embodiment, also comprise on the extension rod parallel with screw rod 4 10, the first fixed blocks 2 or the second fixed block 3 and be provided with the via hole passing through for extension rod 10 gaps, one end of extension rod 10 is fixed on slide block 9, and the other end extends to outside by via hole.In this structure, slide block 9 is not re-used as the main body of displacement drive, and the extension rod 10 extending out is only the enforcement body that direct driving is moved.As shown in Figure 2, in the case, all parts between the first fixed block 2 and the second fixed block 3 can wrap up by a housing A, and the extension rod 10 only extending outside housing A is realized drive actions, this structure has been avoided the exposure of internal structure effectively, plays the effect of protection.
Embodiment of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
