Detailed Description

The present invention will be further described with reference to the following examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.

Example 1

Fig. 1 is a schematic structural diagram of the present invention. Fig. 2 is a usage state diagram of the present invention.

As shown in fig. 1-2, a syringe adapter comprising: the injection device comprises a sleeve connecting bolt 100, an injection pipeline 200 and an injector connecting piece 300, wherein one end of the sleeve connecting bolt 100 is connected with an inlet two-way pipe 400, the other end of the sleeve connecting bolt 100 is connected with one end of the injector connecting piece 300 through the injection pipeline 200, and the other end of the injector connecting piece 300 is connected with an injector 500;

wherein, the syringe connector 300 includes: the injection device comprises an injector bolt 310, an O-ring 320 and a connector aligning piece 330, wherein the O-ring 320 is arranged on the inner wall of the injector bolt 310, the connector aligning piece 330 is connected with the injection pipeline 200, a groove is arranged on the inner side of the connector aligning piece 330, and the connector aligning piece 330 is connected with an injection port of the injector 500 through the groove.

The sleeve coupling bolt 100 is connected to the injection pipe 200 in a penetrating manner, and the sleeve coupling bolt 100 includes: the concentrator comprises a concentrator head 110, a fixing bolt 120 and a casing 130, wherein the concentrator head 110 is connected with the front end of the fixing bolt 120, one side of the thread structure of the fixing bolt 120 is connected with the casing 130, the rear end of the fixing bolt 120 is connected with an injection pipeline 200 through a hole, the casing 130 is connected with an inlet two-way pipe 400 in a wrapping mode, and a groove structure is arranged in the casing 130.

As in the background art, a flow cell requires injection of a cleaning solution, isopropyl alcohol, into the cell during the cleaning process. The inlet two-way pipe 400 has a small inner diameter, and the liquid outlet end is difficult to directly inject, so that the general low-price flow cell of the detection equipment can only inject the liquid, which is inconvenient and also affects the sanitation. And high-end foreign import equipment often has syringe auxiliary fittings, helps the better work of syringe. However, the existing auxiliary equipment has a simple structure, and the main principle is that fittings which can be combined with the inlet two-way pipe 400 and the needle head are added at two ends of the pipeline, so that the sealing performance is improved in the injection process, and liquid leakage is avoided. But the problem is only alleviated due to the simple structure. The utility model discloses just carry out further improvement at injection pipeline 200 both ends, improve holistic leakproofness and some weeping remedy modes.

Referring first to the sleeve coupling bolt 100 shown in FIG. 2, it can be seen that the body of the coupling is a threaded bolt structure having threads. A typical inlet manifold 400 would have internal threads that would mate with the bolts that mate with the syringe adapter. Then sleeve pipe connecting bolt 100 increases concentration head 110, and concentration head 110 tail end is wide, and the front end is narrow, makes the more concentrated of washing liquid injection as the name implies, and the water pressure is bigger, for heavy-calibre inflow, has reduced the problem that directly overflows. Meanwhile, the sleeve shell 130 arranged outside the bolt can be directly matched and connected with the inlet two-way pipe 400 through a gap between the shell and the bolt, so that a sealing structure is formed, and a groove is formed in the sleeve shell 130, so that when part of liquid overflows, the liquid can flow into the groove, and the overflow is avoided.

Next, the syringe connector 300, the connector alignment member 330 of the syringe connector 300 is connected to the front outlet of the syringe 500. Specifically, the connector alignment member 330 has a groove, and the groove is combined and connected with the outer contour of the front outlet end of the syringe 500. The syringe bolt 310 rotates inwardly around the housing at the outlet end of the front end of the syringe 500. And is sealed and fixed with the shell by using an O-shaped ring 320.

The above description has been made of the embodiments of the present invention, but the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
