Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a painless injector, comprising a base plate 1, the equal fixedly connected with riser 2 in both sides at 1 top of bottom plate, sliding tray 19 has all been seted up to one side that two riser 2 leave mutually, the equal sliding connection in inner chamber of two sliding tray 19 has sliding block 18, one side of two sliding blocks 18 runs through and sliding connection has pull rod 3, the equal fixedly connected with clamp plate 4 of the one end that pull rod 3 is relative, be provided with cylinder 5 between the relative one side of two clamp plates 4, the fixed cover 6 of the equal fixedly connected with in bottom of two pull rod 3, through-hole 13 has been seted up on bottom plate 1.

Put cylinder 5 between two clamp plates 4, then two fingers of staff pass fixed cover 6, drive pull rod 3 through fixed cover 6 and move, pull rod 3 drives clamp plate 4 and moves, thereby fix cylinder 5 between two clamp plates 4, then laminate bottom plate 1 with the injection position, staff's another hand is pressed the top of two riser 2, pulling fixed cover 6 drives sliding block 18 and slides, thereby vertically insert the syringe needle of cylinder 5 in the muscle, reduce the pricking pain when injecting, then press the piston of cylinder 5 and inject the injection, accomplish the back of injecting, make bottom plate 1 break away from the human body and drive the syringe needle of cylinder 5 and leave the human body, can change cylinder 5 wholly after loosening fixed cover 6, thereby make this syringe can used repeatedly, and can not take place cross infection.

The clamping rods 7 penetrate through the front sides of the two vertical plates 2, the rear ends of the two clamping rods 7 penetrate through the sliding blocks 18 and extend to the inside of the sliding blocks 18, and the transverse plates 8 are fixedly connected to the front ends of the two clamping rods 7.

Before the injection, insert sliding block 18 with two kellies 7 earlier right, carry on spacingly to sliding block 18 to make bottom plate 1 when laminating with the human body, cylinder 5 and sliding block 18 can not move, make bottom plate 1 can laminate with the human body smoothly, make things convenient for this syringe to use.

The front end and the rear end of one side of the two pressing plates 4 which are separated from each other are fixedly connected with a return spring 9, and the other end of the return spring 9 is fixedly connected with one side of a sliding block 18.

When the needle cylinder 5 is replaced, the return spring 9 enables the two pressing plates 4 to be consistent with the two vertical plates 2 in distance, so that the needle cylinder 5 is located between the two pressing plates 4 when being fixed, and the needle cylinder 5 is fixed more stably.

Stopper 10 has all been run through to two riser 2 relative one sides, and two riser 2 relative one sides all offer with stopper 10 looks adaptation's spacing hole 17.

The quantity of spacing hole 17 is a plurality of, arranges along riser 2's direction of height, inserts the not depth of insertion that the syringe needle of cylinder 5 can be controlled to spacing hole 17 of co-altitude according to stopper 10, increases the universality of this device, further makes this device facilitate the use.

Fixing hole 14 has been seted up to the bottom of bottom plate 1, and the inner chamber of fixing hole 14 is provided with connecting rod 11, and the bottom fixedly connected with support frame 12 of connecting rod 11 for bottom plate 1 can be through support frame 12 and human laminating, in order to avoid cross infection, and support frame 12 is convenient to be changed, thereby further makes things convenient for this device to use.

Equal sliding connection in both ends between 14 inner chambers front sides of fixed orifices and the rear side has stripper plate 15, and the one side that two stripper plates 15 are relative all with the surperficial swing joint of connecting rod 11, the equal fixedly connected with extrusion spring 16 in the one side that two stripper plates 15 leave mutually to the other end of extrusion spring 16 and the inner chamber fixed connection of fixed orifices 14.

The connecting rod 11 is inserted between the two extrusion plates 15, and the support frame 12 is fixed by the elastic force of the extrusion spring 16 without influencing the disassembly of the support frame 12, so that the support frame 12 is convenient to replace.

During the use, put cylinder 5 between two clamp plates 4, then two fingers of staff pass fixed cover 6, drive pull rod 3 through fixed cover 6 and move, pull rod 3 drives clamp plate 4 and moves, thereby fix cylinder 5 between two clamp plates 4, then laminate with the human body through support frame 12, make cylinder 5 perpendicular to injection position, the top of two riser 2 is pressed to staff's another hand, pulling fixed cover 6 drives sliding block 18 and slides, thereby vertical syringe needle with cylinder 5 inserts in the muscle, reduce the thorn pain during injection, then press the piston of cylinder 5 and inject into the injection, accomplish the back of injecting, make bottom plate 1 break away from with the human body and drive the syringe needle of cylinder 5 and leave the human body, can change cylinder 5 after loosening fixed cover 6.
