Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As Figure 1-Figure 2, present invention specific implementation includes that liquid storage fills lid 1, oil inlet rubber seal 3, venthole rubber
Glue sealing ring 4, sealed support 2, floating block 5, sealed support 2 and floating block 5 are installed in liquid storage and fill in lid 1, and floating block 5 is sleeved on sealing
On 2 bottom of bracket and it is connected with venthole rubber seal 4,2 bottom end face of sealed support is connected through oil inlet rubber seal 3
To the end face of fluid reservoir oil inlet 6, liquid storage fills lid 1 and is installed on fluid reservoir oil inlet 6.
As shown in figure 3, liquid storage, which fills 1 inner peripheral surface of lid, is equipped with internal screw thread 11, the connection of internal screw thread 11 is screwed into outside fluid reservoir oil inlet 6
On the external screw thread of circumferential surface, formation is threadedly engaged；Liquid storage fills being threadedly engaged between lid 1 and fluid reservoir oil inlet 6 in actual use
There are gap, ambient atmosphere can be entered in thread pitch.
As shown in Fig. 2-Fig. 3 and Fig. 7-Fig. 8, sealed support 2 includes shrouding disc 21 and is fixedly connected in 21 bottom face of shrouding disc
The guide rod 22 of the heart, shrouding disc 21 and guide rod 22 are integral by injection molding.The top end face of shrouding disc 21 is connected to liquid storage and fills top in lid 1
Face is provided with the air channel 24 of bar shaped on the top end face of shrouding disc 21, and air channel 24 is connected with intermediate venthole 25,21 bottom end of shrouding disc
It is connect through oil inlet rubber seal 3 with the end face seal of fluid reservoir oil inlet 6 around face；21 center of shrouding disc, which is provided with to extend to, leads
The circumferential surface of intermediate venthole 25 into 22 top of bar, 22 top of guide rod is provided with the side venthole being connected to intermediate venthole 25
26。
Annular boss 23 is fixed on 21 bottom face of shrouding disc, 23 bottom end of annular boss is equipped with hook portion, oil inlet rubber seal
3 sets are enclosed outside annular boss 23 and passes through hook portion axial direction support limit.Hook portion prevents the oil inlet rubber when screwing off liquid storage and filling lid
Sealing ring is fallen.Due to consideration that two symmetrical side ventholes 26 in specific implementation, be molded after being inserted by die mandrel and
At, and during moving back plug, it can be interfered with annular boss 23.Therefore annular boss 23 is designed to by two arc bodies
It is arranged symmetrically composition.
The thickness of shrouding disc 21 be less than or equal to liquid storage fill 1 internal screw thread 11 of lid a screw thread width so that shrouding disc 21 along
11 precession liquid storage of internal screw thread fills in lid 1.
As shown in Fig. 2-Fig. 3 and Fig. 9-Figure 11, for 5 movable set of floating block outside guide rod 22,22 bottom end of guide rod is equipped with will
Floating block 5 axially supports the radial elastic buckle structure 27 not fallen, and 5 bottom end of floating block is supported on radial elastic buckle structure 27
On, prevent floating block 5 from sliding due to gravity；5 upper end of floating block is equipped with the protrusion cylinder 54 axially extended, protrusion cylinder 54
Circumferential surface is equipped with outward flange 55, and 4 sets of venthole rubber seal are protruding outside cylinder 54 and passing through 55 axial restraint of outward flange.
Air channel 24 extends radially into 21 edge of shrouding disc from intermediate venthole 25, ensure that liquid storage fills fluid flow inside
Smoothness.
As shown in Figure 3-4, floating block 5 is mainly made of top 51 and lower part 52 by being fixedly welded, top 51 and lower part
Reinforcing rib 53 there are three being all provided in 52, is divided into three sub- chambers for top 51 and 52 inner cavity of lower part by reinforcing rib 53.51 He of top
The arrangement of the sub- chamber in 52 inside of lower part and reinforcing rib 53 is symmetrical above and below.
In specific implementation, floating block top 51 and lower part 52 are connected together by hot plate welding or supersonic welding, and top 51 is under
53 phase of reinforcing rib in portion 52 is welded so that the also corresponding welding of multiple sub- chambers, reaches sealing and cement effect.
The assembling flow path of mechanism assembly of the present invention are as follows:
Sealed support 2 is first screw into liquid storage by the thread pitch that liquid storage fills lid 1 to fill in lid 1, then ventilation will have been assembled
The floating block 5 of hole rubber seal 4 is assembled on guide rod 22, and oil inlet rubber seal 3 is finally assembled to sealed support 2
On annular boss 23.
When work, floating block 5 is located in fluid reservoir oil inlet 6, fills oil liquid in fluid reservoir oil inlet 6.It is encountered when automobile
When bumpy road or automobile start braking, the oil liquid in fluid reservoir oil inlet 6 can be filled with the end of fluid reservoir oil inlet 6 by oscillation
At mouthful, floating block 5 is impacted.
Since 5 global density of floating block is less than oil liquid density, floating block 5 is hit can be along 22 axis of guide rod with buoyancy
To moving up, it is accomplished by the following way that impact force is bigger, the better technical effect of oil resistance sealing effect:
As shown in figure 5, under the Oil shocking that floating block 5 does not receive in fluid reservoir oil inlet 6, venthole rubber seal 4
Positioned at 26 lower section of side venthole, side venthole 26 is unsealed at this time.Ambient atmosphere fills lid 1 and fluid reservoir oil inlet 6 from liquid storage
Between thread pitch in enter air channel 24, then after air channel 24 sequentially enters intermediate venthole 25, side venthole 26
Into inside fluid reservoir oil inlet 6, gas circulation can be realized.
As shown in fig. 6, moving on to guide rod 22 on floating block 5 under the Oil shocking that floating block 5 receives in fluid reservoir oil inlet 6
Top, venthole rubber seal 4. block at side venthole 26.
Ambient atmosphere fills in the thread pitch between lid 1 and fluid reservoir oil inlet 6 from liquid storage and enters air channel 24, then passes through
After air channel 24 sequentially enters intermediate venthole 25, side venthole 26, being blocked by venthole rubber seal 4 not can enter liquid storage
Inside tank oil inlet 6, gas does not circulate.
