Description
Technical field
The invention belongs to dust cap apparatus technical field, more particularly, to a kind of dust-proof sealing structure.
Background technology
In every case to mechanical related object, dust-proof sealing structure can all be touched.Its effect of dust-proof sealing structure turns round and look at name
Think justice, mainly aim at and prevent dust impurity from entering into inside machine components, the running that machine components are damaged with this and use
Life-span.On the market using dust-proof sealing structure mainly realized by dust cap, dust cap various structures various in style,
Wherein with：Thin board type, bearing gasket ring type and seal for pipe joints formula, using at most, are used wider.Circulated on existing market and pipeline
Associated dust cap is mainly based on ring type dust cap.It is arranged on the pipe tail of snap joint, pipe tail end is connected to rubber
On flexible pipe.
The ring type dust cap being circulated in the market, mainly based on sealing and dustproof, it fills in pipe tail and passes through its function
Fluid sealant cast between extruding dust cap and duct wall reaches sealing effectiveness, again to be linked with dust-proof cap header during taking-up
Annulus takes out and carries out the dragging of whole water pipe by pulling annulus in use simultaneously.Meeting during pulling pipeline
Because between user and annulus, unit area stress causes obstacle to user and then affects service efficiency greatly.Using simultaneously
Colliding with of being difficult to avoid that in journey can cause to need the damage of flexible pipe to be protected and female.And such dust-proof sealing structure part
Processing process is complicated, is difficult machine-shaping and installation.
Content of the invention
It is an object of the invention to solving the problems, such as techniques discussed above, one kind is provided in dismounting dust cap and to pull water pipe
When convenient, more safety be also avoided that simultaneously rubber hose transport and using process cause because colliding with damage dust-proof
Sealing structure, its technical scheme is as follows：
A kind of dust-proof sealing structure it is characterised in that described dust-proof sealing structure includes pipe fitting, pipe fitting include pipe tail and
Female, the lower inside of described female is provided with the O-ring seal of salable pipe fitting, is provided with drot gfasplng dust cap in female, and drot gfasplng is prevented
O-ring seal is close in the bottom of dirt lid, and the outside of female is provided with lock；Drot gfasplng dust cap offers draw-in groove, and lock is by withholding
The bottom making whole drot gfasplng dust cap on the draw-in groove of drot gfasplng dust cap acts on and completes the sealing to pipe fitting on O-ring seal；
The upper end of drot gfasplng dust cap is fixed with handle by knurled pin, and one end of knurled pin passes through handle in drot gfasplng dust cap,
The sidepiece of the other end of knurled pin is provided with some bar shaped annular knurls preventing handle abjection, and handle passes through the side of drot gfasplng dust cap
It is plugged in afterwards in the opposite side of drot gfasplng dust cap；The outer wall of described pipe tail is provided with some chamfering boss.
Optimal way is, is provided with shatter-resistant convex at the position that the sidepiece of described drot gfasplng dust cap is located between draw-in groove and handle
Platform.
The dust-proof sealing structure that the present invention provides, the lower inside of female is provided with the O-ring seal of salable pipe fitting, passes through
O-ring seal can be effectively sealed to pipe fitting, plays sealing effectiveness.And latch by withholding the draw-in groove of drot gfasplng dust cap,
O-ring seal is squeezed thus strengthening sealing effectiveness.The upper end of drot gfasplng dust cap is fixed with handle by knurled pin,
Understood during pulling pipeline because between user and handle, unit area stress is little by handle, so that towing pipeline becomes
Obtain enhanced convenience laborsaving, safer.Meanwhile, the sidepiece of drot gfasplng dust cap is located at and is provided with the position between draw-in groove and handle
Shatter-resistant boss.Shatter-resistant boss make this device with during avoid causing because colliding with needing flexible pipe to be protected and female to be subject to
Damage.When using, rubber tubing drops ground or the when of colliding shatter-resistant boss must first contact object of colliding thus protection pipe
The damage that tail head and rubber hose cause because of the effect of external force.
Brief description
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the schematic diagram of drot gfasplng dust cap.
Fig. 3 is the schematic diagram of handle.
Fig. 4 is the schematic diagram of knurled pin.
Specific embodiment
With reference to the bright embodiment of Fig. 1 to Fig. 4：
As shown in figure 1, drot gfasplng dust cap 1 enters in the female 21 of pipe fitting 2, rubber hose is socketed in group on the outer wall of pipe tail 22
Become whole water pipe.Chamfering boss 221 on pipe tail 22 can prevent rubber hose from coming off from pipe tail.Again with being connected in female 21
Lock 3 by withholding so that whole drot gfasplng dust cap 1 is close-coupled in female 21 on the draw-in groove 11 on drot gfasplng dust cap 1,
Drot gfasplng dust cap 1 lower reaction makes O-ring seal deformation to reach the effect that sealing is closed on O-ring seal 6 simultaneously, uses
When hold handle 4 and just can pull whole water pipe or taking-up drot gfasplng dust cap 1.
As shown in figure 3, be drilled with handle 4 round pin via 41 (pin via with diameter greater than pin diameter 0.1mm,
To be advisable being entirely completed handle and do not rock).
As shown in figure 4, the annular knurl 51 (its effect prevents pin from deviating from) of bar shaped is had on knurled pin 5.
As shown in Fig. 2 handle installing hole 13, pin installing hole 14 and draw-in groove 11, drot gfasplng dust cap are had on drot gfasplng dust cap 1
Sidepiece be provided with shatter-resistant boss 12.Wherein shatter-resistant boss 12 design for shatter-resistant (when entirely soft rubber tubing drops ground or
When colliding, shatter-resistant boss 12 must first contact object of colliding thus protection pipe tail head and rubber hose are because of the effect of external force
The damage causing).Handle 4 passes through the handle installing hole 13 on drot gfasplng dust cap 1, makes pin via 41 same with pin installing hole 14
The heart, knurled pin 5 loads the pin installing hole 14 on drot gfasplng dust cap 1 and is fixed on drot gfasplng by the pin via 41 on handle 4
On dust cap 1.Now complete the composition of whole drot gfasplng dust cap.
When using, user grasps the installation and removal that handle just can be easily accomplished drot gfasplng dust cap.This kind of hold
Formula dust cap operates smoothness in process of manufacture, and structure simply it is easy to processing and manufacture, is effectively reduced molding and brings
High cost and the puzzlement being difficult to molding.Can not only have functions that sealing and dustproof in use, more have both and avoid pipe tail
Head and rubber hose are because of the unnecessary damage caused by external force or internal force.Load drot gfasplng dust cap and take drot gfasplng dust cap and
Pull more safe and reliable during whole water pipe, pressure that workman born greatly reduces, thus effectively lifting whole work
Make efficiency and usage safety performance.Use it possess easy accessibility, the advantage that once mounting is suitable for throughout one's life.Producing and making
One-tenth aspect even more greatly reduces the complexity of mould, reduces die sinking cost price, is obviously improved production efficiency.
