DETAILED DESCRIPTION

[0020] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0021] like Figure 1-Figure 5 As shown, a filling needle structure of an embodiment of the utility model comprises a support plate assembly, a filling needle assembly 5 and a guide sleeve 2, wherein the filling needle assembly 5 is mounted in an array on the syringe mounting plate 4 of the support plate assembly. In order to reduce the collision and friction between the needle and the container when the filling needle reciprocates up and down, the guide sleeve 2 is mounted in an array on the lower bottom surface of the guide sleeve mounting plate 3 of the support plate assembly, and is arranged one by one with the filling needle assembly 5; in the original state, the needle 51 of the filling needle assembly 5 extends into the guide sleeve 2, thereby protecting the needle 51; in the filling state, the needle tube 53 of the filling needle assembly 5 enters the guide sleeve 2, thereby limiting the feeding direction of the needle. At the same time, the existence of the guide sleeve 2 can separate the needle 51 from the container, thereby avoiding collision and friction between the needle 51 and the container.

[0022] In order to achieve the feeding limit of the filling needle assembly 5, a guide channel is provided in the guide sleeve 2, and the guide channel is composed of a needle tube channel and a needle channel, wherein the inner diameter of the needle tube channel is adapted to the outer diameter of the needle tube, and the inner diameter of the needle channel is adapted to the outer diameter of the needle. A threaded mounting hole adapted to the guide sleeve is provided on the guide sleeve mounting plate, and the guide sleeve is in a cylindrical sleeve shape and is connected to the threaded mounting hole through a thread.

[0023] In order to reduce the loss cost and facilitate the cleaning of the filling needle, the filling needle assembly 5 includes a pipe connector 54, a needle tube 53, a needle connection end 52 and a needle 51 connected in sequence. The pipe connector 54 is connected to the tail end of the needle tube 53 through a No. 1 bolt 55, and the other end of the needle tube 53 is connected to the tail end of the needle connection end 52 through a No. 2 bolt 56. The tail end of the needle 51 is connected to the head end of the needle connection end 52 through a thread. Among them, the pipe connector 54 is mainly used to connect to the pipe for transporting semen. When the needle 51 is damaged, the needle 51 can be replaced and installed with a new one by manually rotating it to separate it from the needle connection end 52.

[0024] In order to achieve the limited installation of the filling needle assembly 5, a limit block is integrally formed on the outer circumference of the No. 1 bolt 55. During the specific installation, the limit block can be connected to the syringe mounting plate by bolts. The syringe mounting plate is provided with a mounting hole adapted to the filling needle assembly. The filling needle assembly passes through the mounting hole and is vertical to the horizontal plane.

[0025] In this embodiment, the support plate assembly includes a bottom plate 1, a syringe mounting plate 4, a guide sleeve mounting plate 3 and a top plate 6. The syringe mounting plate 4 is mounted above the bottom plate through a telescopic assembly, the guide sleeve mounting plate 3 is mounted below the syringe mounting plate 4 through a No. 1 support rod 10, and the top plate is mounted above the syringe mounting plate 4 through a No. 2 support rod 9. In order to realize the feeding of the filling needle assembly, the telescopic assembly includes an electric push rod 7 and three telescopic sleeves 8. The telescopic end of the electric push rod 7 passes through the bottom plate and is connected to the lower bottom surface of the syringe mounting plate 4, two of which are symmetrically installed between the syringe mounting plate 4 and the guide sleeve mounting plate 3, and the other telescopic sleeve 8 is installed between the syringe mounting plate 4 and the bottom plate 1. When in use, the syringe mounting plate 4 is driven to rise and fall by the electric push rod 7, thereby realizing the up and down reciprocating motion of the filling needle assembly. It is worth noting that when the filling needle assembly reciprocates up and down, the position of the guide sleeve remains unchanged.

[0026] When the present invention is implemented and used, first, the vas deferens is docked with the pipeline connector, and then the packaging bag or packaging bottle and the filling needle assembly are placed in a relatively aligned state by means of a clamp or other tools, that is, the guide sleeve is aligned with the center of the filling port of the packaging bag or packaging bottle. At this time, the electric push rod is started to drive the filling needle assembly to descend until the needle head of the filling needle assembly enters the filling port of the packaging bag or packaging bottle to a certain depth (which can be designed according to different packaging bags or packaging bottles). At this time, the semen filling pump is started to allow the semen to flow through the vas deferens and the filling needle assembly into the packaging bag or packaging bottle. After the filling is completed, the electric push rod is started until the electric push rod is reset, and the needle head can be stored in the guide sleeve.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
