Description

Passive electronic label syringe with damping thrust

Technical field

A kind of syringe is the utility model is related to, is specifically a kind of be used for the read-write animal electronic tag of animal body implantation Have damping thrust passive electronic label syringe.

Background technology

In the past, animal identification is the pigment by smearing different colours to animal body, or clip is different from animal body The modes such as shape, the scale of size or nail are identified, but because distinguishing characteristics is limited, so the identification technology is The needs of can not meeting now.

With radio RF recognition technology (RF I D) development, there are unique encodings, strong antijamming capability, packing forms Various radio electronic label is more and more popular in the application of animal electronic identity card.It is existing to stamp electronic tag to animal body Method be mainly：Electronic tag is overlayed on the epidermis of animal using suspension members such as hook, earrings, such as hung on ear, and or Person is implanted in animal body by opening operation hilt electronic tag.Animal cuticle operation very simple is overlayed on, does not have shadow to animal Ring, but be easy to come off because of mutual collision or friction；Although electronics mark can be avoided by being implanted in animal body Label are come off from animal body, but complex operation is operated in operation, and cost is high, and can produce harmful effect to animal bodies.

Therefore, people introduce syringe in the application of electronic tag implantation animal body, as Authorization Notice No. is CN201020110Y, entitled " a kind of electronic label injector ", and Authorization Notice No. are CN2848165Y, entitled " animal With injection-type electronic identification syringe " two utility model patent, disclose the electronic tag of hand propelled syringe construction Syringe, electronic tag is positioned in the syringe needle of front end of the syringe needle, syringe needle promotes push rod by electronic tag after penetrating animal body Implantation.This implantation is operated on compared to operation, is had the advantages that easy to operate, efficiency high, small to animal bulk damage, is turned into The implantation of present main flow.But this mode still has a shortcoming：During implantation, operator directly promotes push rod manually Electronic tag is pushed into animal body, due to can not accurately control promotion dynamics when human hand operates push rod, causes to be implanted into electronics mark The speed of label is sometimes fast and sometimes slow, and speed is uneven, and larger pain can be caused to animal body, still larger to animal bulk damage.

It is CN201061223Y to have Authorization Notice No. again afterwards, the utility model patent of entitled " electronic label injector ", Spring is installed between syringe and push rod, enters row buffering using the elastic force of spring come the speed of the advance to push rod, compared to upper Damage to animal body can be reduced by stating two kinds of syringes, but the syringe of this structure generates the problem of new again：1st, spring Price add the production cost of syringe；2nd, spring is generally metalwork, to prevent the mutual infection for causing animal body, needs Strict disinfectant program is performed, adds the use cost of syringe.

Utility model content

The utility model purpose is the deficiency for existing electronic label injector, there is provided one kind production and processing convenience, The safe and reliable passive electronic label syringe with damping thrust.

To achieve the above object, technical solution adopted in the utility model is：Passive electronic mark with damping thrust Write comments on a document emitter, including syringe, the push rod that is plugged in syringe, and the syringe needle of syringe front end, electronic tag are plugged in the pin In head, the needle cylinder surface is provided with one group of handle, and an at least damping piece, the resistance are provided between the syringe and push rod Damping member can produce elastic deformation in push rod progradation, and after the thrust revocation of push rod, damping piece can recover deformation and will push away Bar is retracted into reset condition.

According to the utility model of above structure, its further technical characteristic also includes, described damping piece one end and institute State syringe integrated injection molding, the other end and the push rod integrated injection molding.

Further technical characteristic also includes, and the damping piece quantity is two, is symmetricly set in the two of needle cylinder surface Side.

The utility model is pushed away by setting damping piece between syringe and push rod using the elastic force of damping piece to push rod Enter speed and enter row buffering and control, realize the at the uniform velocity implantation of electronic tag, reduce the damage to animal body, due to damping piece with Syringe and push rod integrated injection molding, manufacturing cost is low, and sterilization is easy, has effectively prevented the infection that intersects between animal body.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, a kind of passive electronic label injection with damping thrust described in the utility model Device, including syringe 1, the push rod 2 that is plugged in the syringe, and the syringe needle 6 of syringe front end, electronic tag 7 are plugged in described In syringe needle 6, under the promotion of push rod 2 out of the front end of syringe needle 6 implantation animal body.Needle cap 5 is fixed on the leading section of syringe 1, It is provided with the push rod insertion needle 6 of protrusion in it, is polluted with preventing electronic tag 7 from coming off.The surface of syringe 1 is provided with One group of handle 4, for, as impetus, facilitating syringe to be injected when promoting push rod 2.

An at least damping piece 3 is provided between the syringe 1 and push rod 2, the damping piece 3 is in the progradation of push rod 2 In can produce laterally flexible elastic deformation so that the electronic tag 7 in syringe needle can be ejected and planted from needle tip by push rod 2 Enter in animal body, such as Fig. 4, after injection is completed to extract syringe needle, and the thrust of push rod 2 cancels, damping piece 3 can recover deformation and will Push rod 2 is retracted into reset condition.

Convenience and attenuating production cost, one end of damping piece 3 described in the utility model and the syringe 1 one for processing Body injection molding, the other end and the integrated injection molding of push rod 2, are coupled between the syringe 1 and push rod 2.It is described The utility model is integrally passed through high temperature by damping piece 3 using the plastic cement material with excellent toughness and heat resistance after use Environment disinfected, you can come into operation again, can effectively prevent the infection that intersects between animal body.

To keep the balance in the push rod progradation, the damping piece can use two, three, four or more, To realize the optimization of the utility model product cost, the embodiment that the utility model uses is sets the quantity of damping piece 3 For two, the both sides on the surface of syringe 1 are symmetricly set in.When user promotes the push rod to be injected, the elastic force of damping piece can be passed through Speed to be promoted to push rod enters row buffering and control, realizes the at the uniform velocity implantation of electronic tag, reduces the damage to animal body.
