Embodiment
Technical solution of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings, more to enter one
Step understands the purpose of the present invention, scheme and effect, but is not intended as scope of the appended claims of the present invention
Limitation.
As shown in Figures 1 to 7, a kind of check valve housing that a preferred embodiment of the present invention is provided is consolidated
Surely 10 are constructed, is mainly made up of a seat board 11, a down tube 21 and a mounting seat 31, wherein：
The seat board 11, there is a providing holes 12, and more stretched out by the edge of providing holes 12 and with this
At least hollow-out parts 13 that providing holes 12 is connected.
The down tube 21, there is a top located at the seat board 11 and positioned at the lower section of seat board 11, the down tube 21
The providing holes 12 is directed at, the outside wall surface of the down tube 21 has at least projection 22 protruded outward.
The mounting seat 31, there is set portion 32 on one, and the shoulder extended from set portion 32 on this to outer ring-like
Portion 34, and one extended still further below by the shoulder 34 trap portion 36, set portion 32 and the portion that traps on this
36 inside is spatially connected.Center of set portion 32 has a perforation 321, the portion 36 that traps on this
Bore be more than set portion 32 on this, positioned at the portion 36 that traps enclose in the range of the bottom surface of the shoulder 34 determine
Justice is a press face 341, and the portion 36 that traps stretches out an at least convex portion 361, and this trap portion 36 by
Bottom upwardly extends an at least first passage 362 for a predetermined length, and by the top of first passage 362
To an at least second channel 363 for the horizontal-extending predetermined length in side.
Wherein, the portion 36 that traps from top to bottom is placed on the down tube 21 by the providing holes 12, and should
An at least convex portion 361 is also from top to bottom by an at least hollow-out parts 13, in addition, an at least projection 22
Into an at least first passage 362.The mounting seat 31 is nested with relation foregoing, and rotation one is predetermined
After angle, an at least projection 22 enters an at least second channel 363, an at least convex portion 361
At least partly move to the lower section of seat board 11.
In the present embodiment, for an at least projection 22 quantitatively exemplified by two, this is at least one first logical
It is also two that road 362, which quantitatively corresponds to, and an at least second channel 363 is also quantitatively two.Also,
For an at least hollow-out parts 13 quantitatively also exemplified by two, an at least convex portion 361 is quantitatively i.e. corresponding
Also it is two.Two first passage 362 and two second channel 363 are through the portion 36 that traps.
As shown in Fig. 3 and Fig. 7, after finishing assembly, the mounting seat 31 is placed on the down tube to the present invention
21, and a predetermined angular is also rotated, now, there is part two convex portion 361 below the seat board 11,
And reach and prop up the seat board 11 and so that the effect that the mounting seat 31 will not up depart from；In addition, this is two convex
Block 22 also enters two second channel 363 via two first passage 362 respectively, and by the mounting seat 31
Clip is in the down tube 21.And because the down tube 21 is located at the seat board 11, therefore, the mounting seat 31 is
Dual clip relation occurs between the seat board 11 and the down tube 21, the mounting seat 31 is i.e. by firm
It is fixed on the down tube 21 and the seat board 11, thereby there is good fixed effect, and this is well
Fixed effect is the application emphasis of patent of the present invention, even and if such fixed effect need to carry out survey of dropping
Examination, it can also pass through its test.
It is worth supplement, as shown in Fig. 1 to Fig. 7, in previous embodiment, the shoulder 34 can be with
More outside horizontal-extending alar part 35, the end of alar part 35 has a fixing hole 351；The seat board 11 is also right
A bolt apertures 111 should be equipped with；And it is bolted in this through the fixing hole 351 with a bolt 39 and is spirally connected
Hole 111, and then the alar part 35 is fixed on the seat board 11.Thereby, extra fixed effect can be provided,
The unexpected rotation of the mounting seat 31 can be prevented really.
Further, it is also possible to what is be supplemented is a bit, and in order to provide more preferable fixed effect, the portion 36 that traps
A depression 364 is formed more respectively in the position of the end of two second channel 363, and two projection 22 more divides
A salient point 221 is not formed, and when two projection 22 is located in two second channel 363 respectively, respectively this is convex
Point 221 is embedded in the respectively depression 364.Thereby, it may be such that fixed effect is more preferable.
Also, as shown in Figure 5 to Figure 6, in order to install the convenience of non-return valve, the down tube 21 on top also
A large-diameter portion 211 is cooperatively formed, and the lower half of a non-return valve 91 can be housed, and set portion 32 is then covered on this
In the first half of the non-return valve 91, and the top of non-return valve 91 is protruded by the perforation 321.In addition, the pressure
It is also further between face 341 processed and the apical margin of down tube 21 to form a space S, and make the non-return valve 91
With a ring portion 92, and the press face 341 is formed down a ring wall 342.When mounted, the non-return valve is made
91 ring portion 92 is located in the space S, and the ring wall 342 by the press face 341 and the down tube
The clamping of 21 apical margins, reach the effect of firm combination.The ring wall 342 then further provides for concentrating chucking power
And formed such as the effect bitten.
Certainly, the present invention can also have other various embodiments, in the feelings without departing substantially from spirit of the invention and its essence
Under condition, those skilled in the art work as can make various corresponding changes and deformation according to the present invention, but
These corresponding changes and deformation should all belong to the protection domain of appended claims of the invention.
