Body 1 is together with the cementation of metal pipe sleeve 3；Then seal 4 is placed on the abutting end 23 of sub-assembly 2, while in metal tube
Cover the upper half part coating glue of 3 internal threads 31；Finally sub-assembly 2 is screwed in metal pipe sleeve 3, sub-assembly 2 is compressed pin
Body 1 simultaneously and the cementation of metal pipe sleeve 3 together with, with formation one entirety mount structure.The effect of metal pipe sleeve 3 is to ensure
The sealing and fastness that sub-assembly 2 combines with pin body 1, and the intensity coordinated with external pipe fitting.
As shown in Fig. 4 to Fig. 4 E, embodiments of the invention 2, wherein sub-assembly 20 combined by inner sleeve 201 with overcoat 202 and
Into same pin body 1 forms opening 11 in the end for expanding the position of chamber 10, then the corresponding pin of the inner sleeve 201 of sub-assembly 20 expands chamber
10 superstructures are independently molded, and the top of this inner sleeve 201, which is formed, coordinates step 2011 and junction surface 2012, and bottom is formed and spacious
Mouth 11 is provided with detent mechanism, i.e., on abutting end 2013 with the abutting end 2013 in footpath between this abutting end 2013 and opening 11
Short slot or projection 2014 are formed, then forms projection or short slot 111 on corresponding open 11, is set between abutting end 2013 and opening 11
There is seal 4；Internal thread 31 is formed at the top of the metal pipe sleeve 3, while is formed on the inwall of metal pipe sleeve 3 and supply pin sheet
Body 1 assembles limited step 32 in place and assembles positioning step 33 in place for inner sleeve 201.
During making, machined metal pipe sleeve 3, while injection molding inner sleeve 201 first；Secondly metal pipe sleeve 3 is placed in mould
Pin body 1 is taken shape in metal pipe sleeve 3 in tool, the internal thread 31 in metal pipe sleeve 3 can improve pin body 1 and metal
The fastness that pipe sleeve 3 engages；Then seal 4 is placed on the abutting end 2013 of the inner sleeve 201 of sub-assembly 20, be assembled in together
It is molded in the pin body 1 in metal pipe sleeve 3；It is placed in again afterwards in mould and carries out the overcoat of secondary encapsulated formed combination part 20
202, i.e. overcoat 202 takes shape in the outside of inner sleeve 201 while is combined together with metal pipe sleeve 3, so just forms an entirety
Mount structure.
As shown in Fig. 5 to Fig. 5 F, embodiments of the invention 3, wherein pin body 100 are on the side wall of the position of chamber 10 is expanded
Opening 1001 is formed, is formed on open 1001 tops and coordinates step 1002 and junction surface 1003；The sub-assembly 200 includes one
The water sealing slice 2001 and the cladding top of pin body 100 and water sealing slice of corresponding open 1001 outlines of the side wall of pin body 100
The short slot 2003 for setting seal 4 can be formed on the peripheries that 2001 jacket 2002, this water sealing slice 2001 and opening 1001 coordinate,
Simultaneously be additionally provided with groove 2004 on 2001 outer surfaces of water sealing slice with improve jacket 2,002 2 times it is encapsulated when connect with pin body 1
The fastness of conjunction；The upper portion side wall of metal pipe sleeve 30 correspond to pin body 100 opening 1001 formed breach 301, while
Internal thread 302 is formed at the top of metal pipe sleeve 30.
During making, machined metal pipe sleeve 30, while injection molding water sealing slice 2001 first；Secondly metal pipe sleeve 30 is put
Pin body 100 is taken shape in metal pipe sleeve 30 in mould；Seal 4 is then placed on to the short slot of water sealing slice 2001
In 2003, it is assembled at the opening 1001 of pin body 100；By the pin body 1 combined and water sealing slice 2001 and metal
Pipe sleeve 30, which is placed in injection mold, carries out secondary encapsulated shaping jacket 2002, i.e. jacket 2002 is taken shape in metal pipe sleeve 30, together
When be combined together with metal pipe sleeve 30, water sealing slice 2001 and pin body 100, then machine external screw thread 303 and just form one
Individual overall mount structure.
Certainly, pin body 1 is not limited to the form of above-mentioned three kinds of embodiments with sub-assembly 2, as long as being easy for pin
The Split type structure that chamber 10 is molded is expanded in inside.
In summary, the present invention is by the way that tap pin is independently molded with pin body 1 and sub-assembly 2, then group
Conjunction forms pin and expands chamber 10, the globality and fastness combined by the guarantee of metal pipe sleeve 3 pin body 1 with sub-assembly 2, so as to
Ensure the normal function of tap pin.The faucet tube leg structure of such split shaping can pass through mould using plastic cement material
Injection molding section components therein, not only save material cost, meet environmental requirement, and can effectively reduce and be fabricated to
This, improves the competitiveness of product in market.
Therefore, inventive point of the invention is that tap pin is molded with split, secondary to combine the structure being combined as a whole,
The purpose of split shaping is easy for expanding in pin the shaping of chamber, and metal pipe sleeve combination is to ensure the globality and pin of pin
Sealing and intensity.
It is described above, only it is embodiments of the invention, is not intended to limit the scope of the present invention, thus it is all
It is any subtle modifications, equivalent variations and modifications made according to the technical spirit of the present invention to above example, still falls within
In the range of technical solution of the present invention.
