Description
Technical Field
The utility model relates to a fluid transfer equipment especially relates to a fluid transfer filler.
Background
The filling device is an instrument commonly used in many industries, and the main structure of the filling device comprises a cylinder body, a push rod and a sealing plug, and the filling device has diversified applications, such as medical medicine injection, biochemical reagent transfer, mechanical lubricating oil lubricating grease addition and the like. It is mainly used for transferring or directionally injecting various liquids, gels and other fluids. The existing filler structure has some defects as a whole: firstly, the risk of liquid leakage is mainly reflected in that the sealing effect of the sealing plug is not good enough and the liquid leaks in the transfer process of the filler; secondly, more fluid is remained in the front end of the cylinder body in the injection process at the later stage.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a fluid transfer filling device, its novel structure, it is sealed effectual during liquid transfer, remains few during later stage injection.
The technical scheme of the utility model a fluid transfer filling device, including barrel and the push rod that is located the barrel, the barrel is by including needle portion, toper transition portion and straight section of thick bamboo portion after going to, the push rod is by going to the back correspondence for needle point portion, toper installation department and pole portion, pole portion tail end is provided with the connecting portion of connecting the external equipment, the toper installation department is connected with the sealed flexible glue of toper, the sealed flexible glue of toper maximum outer diameter department keeps sealed with straight section of thick bamboo portion internal diameter interference fit, the surface and the toper transition portion internal surface looks adaptation of the sealed flexible glue of toper, needle point portion surface and needle portion internal surface looks adaptation.
Preferably, the conical mounting part comprises a limiting plate and a plurality of positioning grooves arranged at the front end of the limiting plate at intervals, and a positioning part is arranged on the inner surface of the conical sealing soft rubber corresponding to the positioning grooves.
Preferably, the outer surface of the front end of the conical sealing soft rubber is provided with an annular limiting sealing rib.
Preferably, the material of the cone-shaped sealing soft rubber is silica gel or rubber.
Preferably, the cylinder and the push rod are made of PP, ABS, PE or HIPS.
The utility model discloses an improvement to the push rod structure, improved sealing performance to the volume of remaining has been reduced when the injection.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, the utility model provides a fluid transfer filling device, include barrel 1 and the push rod 2 that is located barrel 1, barrel 1 is by including needle portion 11, toper transition portion 12 and straight section of thick bamboo 13 after going to, push rod 2 is by going to back to correspond for needle point portion 21, toper installation department 22 and pole portion 23, pole portion 23 tail end is provided with the connecting portion 24 of connecting the external equipment, toper installation department 22 is connected with toper seal flexible glue 3, 3 maximum outer diameter departments of toper seal flexible glue keep sealed with straight section of thick bamboo 13 internal diameter interference fit, the surface and the 12 internal surface looks adaptations of toper transition portion of toper seal flexible glue 3, needle point portion 21 surface and 11 internal surface looks adaptations of needle portion.
On the basis of the above scheme, the tapered mounting portion 22 includes a limiting plate 221 and a plurality of positioning grooves 222 arranged at intervals at the front end of the limiting plate 221, and a positioning portion 31 is arranged on the inner surface of the tapered soft seal glue 3 corresponding to the positioning grooves 222.
In addition, the outer surface of the front end of the conical soft sealing rubber 3 is provided with a plurality of annular limiting sealing ribs 32, the annular limiting sealing ribs 32 are arranged at intervals, and the push rod 2 is pushed forwards to be in place and is in contact with and deforms in a limited manner through the limiting sealing ribs 32.
Specifically, the material of the cone-shaped soft sealing glue 3 is silica gel or rubber.
Specifically, the cylinder body 1 and the push rod 2 are made of PP, ABS, PE or HIPS.
The utility model discloses the structure to barrel 1 and push rod 2 has improved for 2 anterior surface shapes of push rod and 1 anterior surface shapes looks adaptations of barrel, the improvement of 22 structures of toper installation department is convenient for cooperate the sealed flexible glue 3's of toper installation department installation, and is sealed effectual at the in-process that the fluid shifted, and during later stage injection fluid, remaining fluid is few in the barrel 1.
The above, it is only the preferred embodiment of the present invention, not to make any restriction on the utility model, all the bases the technical principle of the present invention is to any simple modification, equivalent change or modification made by the above embodiments, still belong to the technical solution scope of the present invention.
