Description
Technical Field
The utility model relates to the technical field of injection articles, in particular to an injector.
Background
The injector generally comprises an injection cylinder and a push rod, wherein the front end of the push rod is connected with a piston, and two circular sealing rings are arranged outside the piston, and are easy to misplace in the assembly process, so that the assembly time is long; in addition, the hole between the piston and the push rod is larger, so that the piston can deform due to the large pressure in the injection cylinder in the use process, the stability is poor, bubbles are generated, and the injection quantity is deviated.
Disclosure of Invention
In view of the above, the present utility model aims to provide a syringe with good stability, low cost and convenient assembly, which overcomes the shortcomings of the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the injector comprises an injection cylinder and a push rod arranged in the injection cylinder, wherein the push rod comprises a push handle and a supporting head in threaded connection with the push handle, and a sealing rubber sleeve is sleeved on the supporting head.
According to the technical scheme, the pushing handle and the supporting head are detachably mounted, so that the application range is wider, and the pushing handle can be directly used or used for an injector after being detached; the rubber sleeve is directly sleeved on the supporting head, so that the assembly of a traditional rubber ring is avoided, the installation is more convenient and quick, the stability of the rubber sleeve is improved by the supporting head, the rubber sleeve and the supporting head are attached together, and the gap between a traditional piston and a push rod is reduced.
Preferably, the supporting head comprises a hollow base with an upward opening, a plurality of connecting blocks are uniformly distributed in the base, an arc-shaped connecting table is arranged at the front end of each connecting block, and the connecting tables are arranged in a threaded staggered manner; and a limiting block is arranged between the adjacent connecting blocks. Because the injector is a disposable medical product, the consumption is huge, the material consumption is reduced, the cost is reduced by arranging the connecting blocks at intervals, and all the connecting tables are in a thread shape and are in threaded connection with the push handle; the stopper is used for increasing the stability of pushing away the handle, avoids it to take place to rock bad power.
Preferably, the pushing handle comprises a cross-shaped connecting rod, limiting plates and pressing sheets, wherein the limiting plates and the pressing sheets are respectively arranged at the front end and the rear end of the connecting rod, the connecting head is arranged at the top of the connecting rod, and external threads matched with thread lines formed by the connecting table are arranged on the connecting head. The limiting plate is used for limiting the supporting head, and the force generated by the pushing handle is more uniformly transmitted to the supporting head; the pressing sheet is convenient to push and press, and the connector is used for being installed together with the supporting head.
Preferably, a limiting groove is formed in the middle of the base, and plastic buckles are symmetrically arranged on two sides of the limiting groove. When the installation of pushing away the handle and supporting head is accomplished, the bottom of connector is located the spacing inslot, and the plastics buckle of both sides is because having certain elasticity can press from both sides the connector tightly fixed, promotes the steadiness of pushing away between handle and the supporting head.
Preferably, the fin of the connecting rod is provided with a mounting hole, a plurality of clamping pieces are uniformly distributed in the mounting hole, and a top cover sleeved at the top end of the injection cylinder is arranged in the middle of the clamping pieces. The top cover and the clamping piece are connected together through spot welding, after the medicament is pumped into the injection tube, the top cover is taken down to cover the front end of the injection tube for later use, and the top cover is prevented from falling.
Preferably, the rubber sleeve is integrally formed, and the shape of the rubber sleeve is consistent with that of the base. The rubber sleeve is integrally formed, so that the assembly efficiency is improved; the rubber sleeve and the base can be better attached, and the stability is good when the rubber sleeve is subjected to the pressure in the injection cylinder.
The beneficial effects of the utility model are as follows:
the utility model has the advantages of detachable installation, wide application range, simple structure, low cost, good stability and good injection stability of the medicament.
