Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As shown in Figures 2 and 3, a kind of waterproof checking cylinder, including brake cylinder casing 1 and protecgulum 2, described protecgulum 2 is arranged
Being formed 3 by waterproof and dustproof cover, described waterproof and dustproof cover composition 3 includes the dust cap 4 being fixedly connected on protecgulum 2 and is arranged on
Filter dirt felt frame 5 in dust cap 4 and filter dirt felt pan 6, the dust filtration felt frame 5 is connected with dust cap 4, and the dust filtration felt pan 6 is fixed
On filter dirt felt frame 5, described dust cap 4 edge, axially arranged have an outward extending train of dress 7 along it, described train of dress 7 with
Checking cylinder dust cap 1 is molded as one structure, and described train of dress 7 entirety is toroidal, described dust cap 4 exhaust ports,
Axially arranged there is outward extending lobe 8 along it, stop that rainwater enters in dust cap further.
As it is shown on figure 3, when rainwater flows down along checking cylinder dust cap, owing to there being the dash of train of dress on dust cap to make
With, rainwater falls directed along at train of dress, thus by gas passage and rainwater trickling circuit isolation, plays waterproof action, work as system
When dynamic cylinder is alleviated, above the filter dirt felt pan of dirt catcher composition, form negative pressure, but owing to rainwater does not arrives under train of dress barrier effect
At the C of dust cap, the most also would not be inhaled in cylinder body；Even there being few part rainwater to flow at C, also can be by C
Lobe again stop, so that it is guaranteed that rainwater cannot be introduced in dust cap.
As shown in Figure 4, in described protecgulum 2, it is provided with the dustproof ring base 11 for installing protecgulum filter konisphere 10, described anti-
Konisphere seat 11 is socketed on the piston rod 12 of checking cylinder, on described dustproof ring base 11, between dustproof ring base 11 and piston rod 12
Being provided with lips dust ring 13, described lips dust ring material is polyurethane, and hardness is higher, reduces the friction with piston rod, energy
Enough prevent rainwater from entering cylinder body at A；On described dustproof ring base 11, between dustproof ring base 11 and protecgulum 2, it is provided with O shape seal
Circle 14, as it is shown in figure 5, be provided with annular groove 9 in the outer face of described dustproof ring base 11, described O-ring seals 14 is assemblied in annular groove 9
In, by the active force of release spring 15, make O-ring seals 14 deform, play sealing function, prevent rainwater from protecgulum with dust-proof
Cylinder body is entered at B between circle mounting seat.Protecgulum filter konisphere sealed by O-ring seals and lips dust ring, it is to avoid with greatly
Gas directly contacts, and the volatilization of the 89M grease that wherein stores reduces, and oxidation deterioration slows down, beneficially the lubrication of piston rod and antirust.
This utility model carries out structure improvement for leaking area at A, B, C in Fig. 1 tri-, rises by sealing the setting of structure
To waterproof action, effectively prevent rainwater to the pollution within checking cylinder and corrosion, improve the service life of checking cylinder, it is ensured that
Traffic safety.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
