Metal plate 36 with holes connects and fixes on motor vehicles；Specifically, during installation, pressure relief device is placed in for pressure relief device
On motor vehicles in metal plate 36 with holes, and flattening bench is pressed by flattening bench 1 and bottom by pressing top platform 02, bottom
2 08, thus by power be transferred to elastic force buckle 1 at the top of pressure relief device, elastic force buckle 2 10 at the top of pressure relief device,
Pressure relief device bottom elastic force buckle 1 and pressure relief device bottom elastic force buckle 2 12；
During clamping, elastic force buckle 1, pressure relief device top elastic force buckle at the top of pressure relief device
2 10, the elastic card above pressure relief device bottom elastic force buckle 1 and pressure relief device bottom elastic force buckle 2 12 etc.
Flexible deformation occurs for cavity 19 that the elastic slice 18 buckled is buckled to elastic card, all elastic force buckles both pass through mounting hole it
Afterwards, the elastic slice 18 that elastic card is buckled restores the state before deformation again, and has been clamped with metal plate 36 with holes on motor vehicles
Finish；
Elastic force buckle 1, pressure relief device top elastic force buckle 2 10, pressure release dress at the top of pressure relief device
After bottom set portion elastic force buckle 1 is finished with mounting hole clamping with pressure relief device bottom elastic force buckle 2 12 etc., sealing
Circle 04 will deform, and be tightly attached on mounting plane, to play the role of sealing and waterproof (see Figure 16)；
01 gluing, sealing of water retaining brim is in the metal plate surface；
The water bar connects cross-brace muscle 16 by water bar root hinge structure 22, and is arranged on the water bar
There is buckle, being linked together with will pass through the buckle for cross-brace muscle 16 with valve block.
Such as Fig. 5-6, the buckle is that barb type buckles, and barb type buckle 21 includes the barb apparatus 24 being wholely set
Main part 23 is buckled with barb type, barb type buckles main part 23 and the barb apparatus 24 that barb type buckles is connected to gear
In water bar 03.
Such as Fig. 5-6,03 structure of water bar with buckle is set as when applying pressure to above with the water bar 03 buckled, and band buckles
Water bar 03 can be by bending at water bar root hinge structure 22, and the water bar 03 with buckle is in curved mistake
Cheng Zhong, hole 25 of the barb apparatus 24 that barb type buckles on the hole 27 and cross-brace muscle constantly on valve block is close, into one
The water bar 03 of pressing belt buckle is walked, then the barb apparatus 24 that barb type buckles is by the hole 27 sequentially passed through on valve block and laterally
Hole 25 on supporting rib.
Wherein, 24 size of barb apparatus on barb type buckle is big compared with the hole 25 on cross-brace muscle, and structure is set as wearing
The moment in the hole 25 on cross-brace muscle is spent, the barb dress that the hole 25 on cross-brace muscle deforms and barb type is allowed to buckle
It sets 24 to pass through, the barb apparatus 24 on barb type buckle is behind the hole 25 on the hole 27 and cross-brace muscle on valve block and stops
The bottom in the hole 25 on cross-brace muscle is without deviating from.
In the present embodiment, the shape of the barb apparatus 24 is arrow shaped structure, and 12. buckle (21) due to barb type
Form there are many, Figure 10 as another embodiment, lists barb type buckle-form 2 28, be the hook-shaped knot of L-type
Other forms 29 of hole-on structure and cross-brace muscle；Figure 11 lists barb type buckle-form 3 30, for conical umbrella
Shape structure；Figure 12 lists barb type buckle-form 4 31, is T-type flat structure.
As another embodiment, the buckle is the sheet body 33 without barb, should be without the end of the sheet body 33 of barb
It is linked together behind the hole 25 on cross-brace muscle using sweat soldering, the water bar 32 with sheet body passes through water bar root
Hinge arrangement 22 occur bending and deformation, and allow the sheet body 33 without barb, sequentially pass through hole 27 and cross-brace on valve block
Hole 25 on muscle.After stretching out the hole 25 on cross-brace muscle without the sheet body 33 of barb, to the sheet body 33 without barb
End is heated, and forms the form 34 after the sheet body welding without barb as shown in figure 14.Due to welding after without fall
The sheet body end of hook is connected as one with the hole 25 on cross-brace muscle, or has been greater than without the tip dimensions of the sheet body 33 of barb
The size in the hole 25 on cross-brace muscle, therefore can be taken off from the hole 25 on cross-brace muscle to avoid the sheet body 33 without barb
Out, so as to fixing the upper end of valve block 06 by the hole 27 on valve block.
Wherein, it is provided with one or more positioning pin 05 on the cross-brace muscle, is provided on the valve block and institute
The location hole of detent fit is stated, 05 shape of positioning pin is also possible to cylindrical or analogous shape, and the purpose is to be used for guiding valve
Piece 06 is more easily placed on accurate position before fixation.
Wherein, water flow is provided on the cross-brace muscle dredge muscle and water storage tank.
The valve block support chip 13 is connected on cross-brace muscle 16 in a manner of arrangement, and abuts the bottom of valve block 06
Portion.Valve block 06 can be opened using thin and pliable and flexible deformation material when valve block 06 is opened easily；When valve block 06 is closed
When, valve block support chip 13 can play effective supporting role for valve block 06, due to cross-brace muscle 16, barb type buckle 21
And the water bar 03 with buckle has carried out closed fixation to the hole 27 on valve block, and the position in a manner of arrangement of the hole 27 on valve block
In the top of valve block 06.When valve block 06 be under pressure difference and when needing to open, 06 lower part of valve block can bending deformation easily, and surround
Barb type buckles the rotation that certain angle occurs for 21 regions, sees Figure 15, Figure 17.
The cross-brace muscle 16 is equipped with 35 structure of groove on cross-brace muscle, which is set as sending out when valve block 06
When raw rotational angle variation, the top edge 26 of valve block can be fallen into the groove 35 on cross-brace muscle, so that valve block 06 be promoted to hold
Easily open.
The present invention integrates barb type buckle on water bar, and one-pass molding may be implemented in integrated-type water bar, and can pass through
Directly pressing realizes that self-locking or Simple welding mode easily fixes valve block.Product after being installed, compared with the existing technology,
It can completely avoid the sealing effect that water flow pours valve block back and breaking plant.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
