Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Fig. 1 to Figure 18, this be used for water-band connect cassette in expanded joint head 1 comprise male connecting portion 2 and a female connecting portion 3, this public connecting portion 2 comprises a public access and refutes cylinder 4 and a locking slip ring 5, this female connecting portion 3 comprises a mother and to plug into cylinder 7 and a locking clasp 8, this locking clasp 8 is connected separably with this locking slip ring 5, and this public access refutes the expansion collar 11 being respectively equipped with a dismountable annular in cylinder 4 and female cylinder 7 of plugging into.
The inwall that this public access refutes cylinder 4 is provided with one and is dashed forward the public seal groove 42 of array and an annular by public affairs expansion tooth 41 public affairs expansion teeth formed of dashing forward, the plug into inwall of cylinder 7 of this mother is provided with one and is dashed forward female seal groove 72 of array and an annular by mother's tooth 71 mothers formed tooth that expands of dashing forward that expands, a separable sealing ring 10 is respectively equipped with in this male seal groove 42 and female seal groove 72, this public expansion tooth dash forward 41 projected direction refute the inside of cylinder 4 towards this public access, this female expansion tooth dash forward 71 projected direction to plug into towards this mother the inside of cylinder 7.
This expansion collar 11 is that copper is one-body molded, certainly, also can adopt other suitable metal materials.
Sealing ring 10 is made for rubber, certainly, also can adopt other elastomeric material.
When needs public access refute cylinder 4 to be connected with first water-band 6 be connected time, as shown in Figure 5, first in the public seal groove 42 that public access refutes the bottom of cylinder 4, put into a sealing ring 10, and expansion collar 11 be nested into the head of the first connection water-band 6.Then the first connection water-band 6 of cover overexpansion collar 11 is extend into public access to refute in cylinder 4.Finally, external decompressor is utilized to expand to expansion collar 11.Expansion collar 11 extrudes the first connection water-band 6, makes the outer wall of the first connection water-band 6 be close to public access and refutes cylinder 4, this completes public access and refutes cylinder 4 is connected water-band 6 connection with first.After expansion completes, expansion collar 11 closely props up sealing ring 10.
Same reason, mother's cylinder 7 and second of plugging into connects water-band 9 and completes same connection.
The inwall of refuting cylinder 4 due to public access is provided with to be dashed forward array by public affairs expansion tooth 41 public affairs expansion teeth formed of dashing forward, and effectively can increase the frictional force between inwall that public access refutes cylinder 4 is connected water-band 6 outer wall with first, effectively prevent getting loose of the first connection water-band 6.Because expansion collar 11 closely props up sealing ring 10, the sealing property of public connecting portion 2 effectively can be improved, successful, with low cost.
As shown in Figure 16 to Figure 18, it is the second embodiment of expansion collar of the present invention.This expansion collar 110 comprises the collar body 1101 of a cylindrical shape, and the top of this collar body 1101 is provided with the expansion outwardly outstanding 1102 of an annular, and the cross section semicircular in shape of 1102 is given prominence in this expansion.After expansion collar 110 is inflated, this expansion gives prominence to 1102 effectively can increase the contact area with sealing ring 10, thus effectively improves sealing area, thus improves the sealing of joint further.
In addition, owing to adopting built-in water-band connected mode, avoid the excessive friction of the water-band of joint, long service life, good reliability, resistance to pressure is strong, is applicable to the connection of various water-band.
Be not limited to this, any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
