Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1 and 2, the utility model provides an oral liquid injection assembly, which comprises an injection tube 1 and a sealing cap 2. One end of the liquid injection pipe 1 is a taper pipe end 11. The outer wall of the liquid injection pipe 1 is sleeved with a threaded sleeve 3, and the threaded sleeve 3 is connected with the liquid injection pipe 1 in a welding mode. The threaded sleeve 3 is provided with external threads. An integrally formed retaining ring 31 is arranged at one end of the threaded sleeve 3, which end faces away from the tapered pipe end 11, and the diameter of the retaining ring 31 is larger than the outer diameter of the threaded sleeve 3.

Referring to fig. 3, the sealing cap 2 is a tube structure and has a connecting portion 21 and a fitting portion 22, wherein the inner wall of the connecting portion 21 is provided with an internal thread adapted to the threaded sleeve 3, and the inner wall of the fitting portion 22 is provided with a conical surface adapted to the outer wall of the conical tube end 11.

In specific use, a conduit 4 for supplying liquid medicine is passed through the sealing cap 2, the conical tube end 11 is inserted into the conduit 4, the conduit 4 and the conical tube end 11 are attached, and then the sealing cap 2 is screwed on the threaded sleeve 3. As the sealing cap 2 is moved, the cone end 11 and the abutment 22 are gradually brought closer together until the abutment 22 clamps the catheter 4 against the cone end 11. Under the effect of the conical surface, the guide tube 4 can be firmly fixed on the conical tube end 11, and meanwhile, the operation of fixing the guide tube 4 is convenient and quick, and a good sealing effect can be achieved. In addition, the use of a tapered surface has the advantage that the catheter 4 can be removed as soon as the tapered end 11 and the abutment 22 of the catheter 4 are released, without the need to continuously screw the sealing cap 2 and unscrew the sealing cap 2, which also simplifies the operation during maintenance or cleaning.

With reference to fig. 4, further the setting is, the utility model discloses a structure is still including the backup pad 5 that is used for supporting fixed notes liquid pipe 1, has seted up a plurality of through-holes 51 in the backup pad 5, and the diameter of through-hole 51 is less than the diameter of retaining ring 31 but is greater than the external diameter of screw sleeve 3, annotates liquid pipe 1 by supreme through-hole 51 that passes down, offsets until retaining ring 31 and backup pad 5's lower surface, at last when installation pipe 4 directly revolve twist sealed cap 2 to sealed cap 2 and backup pad 5 the upper surface can. The clamping of the sealing guide pipe 4 is realized in the process, the fixing of the liquid injection pipe 1 is also realized, the operation is simpler and more convenient, the use of structural members is reduced, the processing steps are reduced, the structure of the liquid injection pipe 1 can be more fully utilized, and the liquid injection pipe 1 and the support plate 5 are relatively fixed by using the structural members and the bolts and nuts because the novel structural members for fixing are required to be designed for fixing the liquid injection pipe 1 in the prior art.
