Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described in further detail.
As shown in Figure 1, the utility model includes bottom cover 1, sealing ring 2, spiral cover 3 and dust-proof vent cap 4, set inside spiral cover 3
There is screw thread, screw thread is set as the fold shape with anti-brake fluid impact for being tightened to liquid storage tank mouth, 2 main body of sealing ring when installing
Shape is simultaneously mounted on inside spiral cover 3, and 2 top of sealing ring is equipped with outward flange, and outward flange is threaded into spiral cover 3 by 3 inner wall of spiral cover
It is interior and connect with 3 inner top surface of spiral cover；2 bottom of sealing ring is provided with the mounting hole 8 for installing bottom cover 1, and bottom cover 1 is mounted on sealing ring
In 2 mounting hole 8.
As shown in figs 6-8,3 top of spiral cover is provided with through-hole, and through hole inner end is fixedly connected with notched boss 11, sealing
It encloses notch and through-hole of 2 inner cavities through boss 11 to communicate, in fluid reservoir high vibration, after brake fluid enters sealing ring, this is lacked
Mouth boss 11 can further decrease brake fluid and reach the speed at the outer top of spiral cover and guarantee ventilation inside and outside spiral cover.Outside 3 top of spiral cover
Equipped with annular installation base, connection ambient atmosphere is installed in annular installation base and is put into dust-proof vent cap 4.
As shown in Figure 3 and Figure 5, the top edge of outward flange is set as the laciniation 9 for reinforcing brake fluid sealing.When
When spiral cover and fluid reservoir are tightened, the presence of laciniation 9 can ensure that brake fluid will not be from 3 side leakages of spiral cover.In fold shape
Shape, when brake fluid vibratory impulse in fluid reservoir, since the resilience effect of sealing ring can alleviate brake fluid to a certain extent
Impact.
As shown in figs. 9-11, annular installation base inner wall, which is evenly distributed, sets there are four groove 10, dust-proof 4 surrounding of vent cap
It is evenly distributed and sets there are four convex block 13, convex block 13, which is inlaid in groove 10, forms positioning.4 four convex blocks 13 of dust-proof vent cap
One of them is equipped with the ventilation hole 12 communicated with ambient atmosphere, and dust-proof 4 bottom surface of vent cap is provided with to be communicated with 3 top through-hole of spiral cover
Centre bore, communicated between ventilation hole 12 and centre bore by the connectivity structure inside dust-proof vent cap 4.Ventilation hole 12 is protected
Card spiral cover inner air is communicated with atmosphere.
As shown in figure 4, hole end surface surrounding is equipped with the cylinder groove 7 for ventilation inside and outside mounting hole 8.When bottom cover 1 installs
Cheng Hou is communicated inside sealing ring with braking sap cavity since the presence of cylinder groove 7 can guarantee.
As shown in Fig. 2, 1 section of bottom cover, in I-shaped, I-shaped both ends are of different sizes, and small end is connected to 8 exit orifice of mounting hole
End face, big end are connected to hole end surface in mounting hole 8, with so that brake fluid is not easily accessible in sealing ring 2.When being braked in fluid reservoir
When liquid vibratory impulse, brake fluid is entered inside sealing ring by the cylinder groove 7 of sealing ring bottom, since long side is mounted on sealing ring
Inside can reduce brake fluid and enter flow velocity inside sealing ring.
As shown in Fig. 4 and Figure 11, the connectivity structure inside dust-proof vent cap 4 is set as honeycomb structure, this honeycomb structure
Presence can reduce the flow velocity of brake fluid again.
The utility model assembly and work are following processes:
First bottom cover 1 is installed on inside sealing ring 2, then the sealing ring 2 equipped with bottom cover 1 is packed into inside spiral cover 3, is finally existed
Dust-proof vent cap 4 is loaded onto outside spiral cover 3, i.e. fluid reservoir cap assembly is installed.When work, when fluid reservoir high vibration and up and down
When the emergency braking of slope, brake fluid can impact sealing ring, at this point, reducing since sealing ring 2 has preferable resilience effect
The vibration frequency and impact velocity of brake fluid.Meanwhile and due to bottom cover 1, spiral cover inner top notch boss 11 and dust-proof ventilation
The choked flow effect of honeycomb structure inside lid, it is almost guaranteed that brake fluid toward permeability outside liquid storage cover, does not reach really
The oil-tight effect of brake fluid in fluid reservoir.
