Description of the new model: [Technical field to which the new model belongs] This creation is related to the improvement of a kind of injection syringe, especially to improve the technical field of needles by means of combining the precision of the needle end of the barrel with the needle position. It belongs to the therapeutic injection =, the known structure of Mystery, after the injection, the needle can be pulled back into the injection cylinder, and then the structure is destroyed and / or reused, and the safety effect is obtained when it is discarded. 2 ^ = Heavy number "Micro-dose safety injection syringe, No. 842070 5 Convenient discarding safety ㈣, No. _ infection 5 3 獍 Improved structure of safety injection syringe U, or No. 8 7 2 009 3 No. safety The structure of the injection syringe is shown in the patent of the above-mentioned Ann's shot. ♦ The common characteristics of injection safety technology related to feeding are: —needle = a pusher, —needle position, and —safety injection syringe in the car field, insert the needle seat, = the needle at the front end of the syringe, and carefully Cooperate with the method to prevent the needle seat from Renstoluo, but the turnable area _f professional reading money end hole is provided with a-straight tender accommodation hole, and at the edge of the hole-neck 1 push talent _ A -__ cap is provided. In this way, after the operator injects the potion with a pusher, he can _touch the person_ into the hole in the seat, and hook the neck with the hook cap to link the needle to the needle seat. ―And pull back into the syringe. § The design of the conventional putter to pull back the needle seat is also M281641 due to the matching precision. It makes it difficult to make clothes and make each other '. In detail, in order to make the putter less labor-intensive, the needle seat The tightness of the syringe must be reduced. However, although the resistance can be changed to the face as the face is in the needle, the bribe resistance is too large and the effect of the injection is lost, and even the tightness is tight ... When turning forward to push the shape of # 水, the putter was formed Γ silk made Mizusaki and combined with the material, "who may also cause the needle seat to leave the syringe. On the other hand, the close connection between the needle holder and the needle socket at the front end of the syringe will cause the push rod to pull back, and the push-pull fishing cap will be separated from the needle holder. Naturally, it is impossible to achieve a safe pull-back design because the needles of the same hard material are difficult, and the cylinder can be renewed. If you want to control the miscellaneous parts of the cigarette, the appearance of the product is as needle-shaped as the barrel = seat age. Touch

T = plastic =: = Γ head seat 'The injection molding of the syringe and needle gan through different molds is also impossible to achieve the expected accuracy. One of the shortcomings is even the problem of micro-deformation of the mold for injection molding under high temperature for a long time. This small deformation is another key factor leading to the above-mentioned deficiencies for the seat, the overall syringe structure, Ejin really needs to come up with an effective solution. U 知 M281641 [New content] The money of this creation is simple, but the cost is too high. In order to achieve the precision of precision and the creative spirit of cost, this creation will use plastic syringes. Injection molding sound application: the second reading type is a cylindrical plastic skeleton, and the plastic skeleton is externally covered with the rubber-to-rubber hybrid injection, and the rubber-to-plastic inner diameter hole is formed into the needle ^ The outer diameter of the seat is very sharp. When the needle seat is inserted into the needle socket, it can be elastically deformed by the inner layer to record the large acorna. ^ Repeating the structure of the sister-in-law, please cooperate with the drawings and the examples to explain later. [Embodiment] This creation relates to an injection syringe and a syringe using the same. Please refer to the first and second figures of the figure. The syringe includes: Needle question (1 Q), which is-hollow, the hollow The front end of the syringe (⑴) is extended with a small diameter needle socket (11), and the end of the syringe (10) is extended with an enlarged push-pull part (i 2), and the inner part is formed into the through part. The accommodating empty push rod (14) is sleeved in the accommodating space (13) of the syringe (10), and slides linearly in the accommodating space (i 3). The pushing part (丄 4 1) 'The rear end is formed with an abutting part (1 4 2) larger than the accommodation space; a needle structure (1 5) includes a long round needle seat' (i 5 workers ) And hollow slender needle body (丄 5 2) inserted in the needle base (i 5 i), the needle base (1 $ M281641 1) is inserted into the ring convex 1 on the inner wall surface of the needle socket (Sichuan, fine needle socket ⑴) Form a side of W to combine _, and acupuncture (i 5! Bu end is preset to open >> into a concave positioning groove (1 5 3) · And the main improvement of this creation is (refer to three, five ,six ) · Small-diameter needle socket (11) with the front end of the syringe (10), the way in which the needle socket (! I) is formed, ^ ^ plastic tip 1 (1〇) when molding 'front-body extension-plastic skeleton Body (16), remote recording skeleton body (16), as shown in the third picture, 'is a plurality of circular convex pillars (m) spaced apart from the ring (also can use a single thickness, ring pillar appearance), The top of each convex 枉 (ι 0 亚) Ya Chengcai connects the _ (i 6 2) of each convex post, and the structural strength of the fine contact body (工 6); it is covered by the outer layer of the plastic skeleton (16) (referring to the skeleton The inner and outer edges of the body) are fixed-a hybrid (i 7) made of a brewable enamel material, a combination of a professional body (丄 7) and a skeleton body (1 6), which can be taken to ride In the coating method, the hollow rubber money corresponding to the inner and outer edges of the corresponding skeleton body (1 6) is shot in advance, and then separately set. Regardless of the rubber victory elastomer (i 7), the skeleton body is directly inserted into the mold and rubber material is applied. The second shot i covers the hand and then the first lamp opens a mold to shoot a hollow rubber cover body shape, which uses the unique deformation of the rubber material itself, side to do rubber Elastomer mold, only need to open a mold with lower cost and general accuracy, can achieve the high precision and tight combination of the needle seat and the needle socket when the material is combined, and it is easy to be pulled back by the pusher after turning over Into the syringe to form a safe injection that cannot be reused ° The outer body of the above-mentioned skeleton (i 6) of the elastomer (丄 7), the inner wall hole M281641 of the inner edge is slightly smaller than the needle seat (inward) A ring-shaped convex (丄 7 i) is formed, and when Sui Li :: the body (1 7) inside the wall 1), the needle seat (15 i) η 1 5 1) is inserted into the needle socket (1 in a state of one fold. * _ Convex (1 7 1) Concave and convex, but the shape of the wealth and money g needle silk needles are finely mined with a hard plastic skeleton (1 ,,, ^ wood is margin) molding-better elasticity step green , Buyue, the outer layer of the skeleton (with a better elastic deformation space inside and outside is excellent = rubber riding elastomer (17) 'by the rubber itself, it can make the needle seat nt diameter hole slightly smaller than the needle seat (151) set ( 17. §_ 5 1) Insert the needle socket, _, the rubber (1 7) will produce an elastic recovery force for the needle seat f with ... (151), this creation uses a rotating pin needle with good elasticity and frequency conversion. ： The advantage of Hsinmu Jia, can indeed reach the needle seat, and then the secret prostitute Yu Hewei, Ke Lusheng needle Gu Gu or prolapse; the needle seat of the force, once can, check and rubber pinch is pushed When the rod is pulled back, it only needs to be properly pulled back into the syringe, which will not cause pull back effort at all; the rubber body of the inner edge of the three 'needle socket is designed with rubber material, and the ordinary one can be used. = Cheng !, it can achieve the effect of combining with the high precision of the needle seat. For the economic level, the creators are in line with the laws of economic interests and competition in the mall. Fertile conditions. As for the skeleton of the needle socket (work 6) is made of plastic material, the main consideration is the green turn riding method of the needle socket, which is limited by the material properties: missing, However, it can not achieve excellent bonding, and the two structural parts are respectively: the same material [read from 'the joint does not have any connection knots to strengthen, and its bonding strength is insufficient. M281641 = lack of neglect, torn apart] ㈣ 物-and extended the moon frame (i 6) of the convex column 2 to facilitate the subsequent consolidation of the rubber elastic body and the plastic skeleton ^ is a combination of stability and effectiveness, _ (丄 6) round Shaped convex column (the surface of the Yade ring is provided with grooves or embossed ribs to increase the number of calendar branches between the skeleton and the elastomer to achieve a closer occlusion effect between the two materials. Private and 'the above structure The discussion is mainly based on 3 ~ 5 ee syringes. If a syringe with an i α injection volume is used, 'the area of resistance between the needle socket and the needle seat is greatly reduced (due to the work = the circumference of the syringe is smaller than Small, so the friction area after the two are also relatively small), report = dry forward push riding version plus outline, _ gradually The bottom surface is that the resistance of the needle in the state of force is less than the force of the push rod. The needle = will cause the loss of the control system that is out of the needle socket. Chishu turned limbs called the seventh and eighth red k injection cylinders' Although the resistance surface between the needle socket (1 U and the needle seat (-1 5 i) is 22: The rubber elasticity of the inner edge layer of the needle socket Body (1 7), its rubber material has better characteristics of the shape of the space. The elastic reset clamp after positioning of the needle seat is inserted, and then it is supplemented by the elastic body _ face ring convex (^) and the miscellaneous groove of the needle seat ( The bumps in the second job can make up for the reduction of the resistance area of the needle socket, and then = the effect of the flap in the needle socket. It can be seen from this that the technical method of creating rubber in this article is excellent for the formation of a syringe with a large injection volume. 10 M281641 [Brief description of the drawings] The first figure is a schematic partial cross-sectional view of the syringe of this creation.
