Description
Technical field
The utility model belongs to dust plug apparatus technical field, relates in particular to a kind of dust-proof sealing structure.
Background technique
In every case to mechanical relevant object, all can touch dust-proof sealing structure.It acts on dust-proof sealing structure as its name suggests, and main is exactly in order to prevent that dust impurity from entering into mechanical parts inside, running and the working life of damaging mechanical parts with this.The dust-proof sealing structure used is on the market mainly to realize by dust plug, and dust plug structure various in style is various, wherein uses at most with: thin board type, bearing gasket ring type and seal for pipe joints formula, uses wider.The dust plug that on existing market, circulation is associated with pipeline is mainly taking ring type dust plug as main.Be arranged on the pipe tail of rapid pipe joint, pipe tail end is connected in rubber hose.
The ring type dust plug that circulated in the market, its function is mainly taking sealing and dustproof as main, it is filled in pipe tail and reaches sealing effect by the sealer cast between extruding dust plug and tube wall, when taking-up, takes out and in use carries out pulling of whole water pipe by pulling annulus again with the annulus being linked with dust plug head simultaneously.In the process that pulls pipeline, can cause obstacle and then affect utilization efficiency to user greatly because unit area between user and annulus is stressed.Colliding with of simultaneously being in use difficult to avoid can be caused the flexible pipe that needs protection and the damage of female.And this type of dust-proof sealing structure component processing production process complexity, be difficult for machine shaping and installation.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provide a kind of dismounting dust plug and convenient while pulling water pipe, safety can also avoid rubber hose to cause the dust-proof sealing structure of damage because colliding with in transport and using process simultaneously more, its technological scheme is as follows:
A kind of dust-proof sealing structure, it is characterized in that, described dust-proof sealing structure comprises pipe fitting, pipe fitting comprises pipe tail and female, the lower inside of described female is provided with the O-ring seal of salable pipe fitting, in female, be provided with and hold formula dust cover, hold the bottom of formula dust cover and be close to O-ring seal, the outside of female is provided with snap close; The formula dust cover of holding offers draw-in groove, and snap close makes whole bottom of holding formula dust plug act on O-ring seal, to complete the sealing to pipe fitting by withholding on the draw-in groove of the formula dust plug that is in one's hands; The upper end of holding formula dust cover is fixed with handle by knurled pin, one end of knurled pin is located at and is held in formula dust cover through handle, the sidepiece of the other end of knurled pin is provided with some bar shaped annular knurls that prevent that handle from deviating from, and handle plugs in the opposite side of the formula dust cover that is in one's hands through a rear flank of holding formula dust cover; The outer wall of described pipe tail is provided with some chamfering boss.
Optimal way is that the position of the sidepiece of the described formula of holding dust cover between draw-in groove and handle is provided with shatter-resistant boss.
The dust-proof sealing structure that the utility model provides, the lower inside of female is provided with the O-ring seal of salable pipe fitting, can effectively seal pipe fitting by O-ring seal, plays sealing effect.And snap close is by withholding the draw-in groove of holding formula dust cover, thereby make the O-ring seal enhanced leaktightness effect that is squeezed.The upper end of holding formula dust cover is fixed with handle by knurled pin, can be stressed little because of unit area between user and handle in the process that pulls pipeline by handle, become more convenient and strength-saving, safer thereby make to pull pipeline.Meanwhile, the position of the sidepiece of holding formula dust cover between draw-in groove and handle is provided with shatter-resistant boss.Shatter-resistant boss makes this device with avoiding causing the flexible pipe and the female that need protection to be damaged because colliding with in process.Thereby shatter-resistant boss must first contact the damage that collide object protective tube tail head and rubber hose cause because of the effect of external force when rubber tubing is dropped ground in use or while bumping.
Brief description of the drawings

Fig. 2 is the schematic diagram of holding formula dust cover.
Fig. 3 is the schematic diagram of handle.
Fig. 4 is the schematic diagram of knurled pin.
Embodiment
Below in conjunction with the bright embodiment of Fig. 1 to Fig. 4:
As shown in Figure 1, hold formula dust plug 1 and enter in the female 21 of pipe fitting 2, rubber hose is socketed on the outer wall of pipe tail 22 and forms whole water pipe.Chamfering boss 221 on pipe tail 22 can prevent that rubber hose from coming off from pipe tail.By withholding on the draw-in groove 11 of holding on formula dust plug 1, the whole formula dust plug 1 of holding is closely connected in female 21 with the snap close 3 being connected in female 21 again, hold formula dust plug 1 lower reaction simultaneously and on O-ring seal 6, make O-ring seal deformation to reach the effect that closes of sealing, when use, hold handle 4 and just can pull whole water pipe or taking-up and hold formula dust plug 1.
As shown in Figure 3, the diameter that is drilled with round pin via hole 41(pin via hole on handle 4 is greater than pin diameter 0.1mm, does not rock and is advisable to complete handle in whole assembling).
As shown in Figure 4, on knurled pin 5, there is its effect of annular knurl 51(of bar shaped to prevent that pin from deviating from).
As shown in Figure 2, hold jug mounting hole 13 on formula dust plug 1, pin mounting hole 14 and draw-in groove 11, the sidepiece of holding formula dust cover is provided with shatter-resistant boss 12.Wherein shatter-resistant boss 12 for shatter-resistant design (thereby in the time that whole soft rubber tubing is dropped ground or the time of bumping shatter-resistant boss 12 must first contact the damage that collide object protective tube tail head and rubber hose cause because of the effect of external force).Handle 4, through the handle mounting hole 13 of holding on formula dust plug 1, makes pin via hole 41 concentric with handle mounting hole 13, and knurled pin 5 packs the pin mounting hole 14 of holding on formula dust plug 1 into and is fixed on and held on formula dust plug 1 by the pin via hole 41 on handle 4.Now complete the whole composition of holding formula dust plug.
In use, user grasps handle and just can easily complete the installation and removal of holding formula dust plug.This kind held formula dust plug and in process of manufacture, operated smoothly, simple in structure, be easy to processing and manufacture, effectively reduced that moulding brings expensive and be difficult to the puzzlement of moulding.In use can not only there is effect of sealing and dustproof, more have both the unnecessary damage of avoiding pipe tail head and rubber hose to cause because of external force or internal force.Hold formula dust plug and get when holding formula dust plug and pulling whole water pipe more safe and reliablely packing into, reduced greatly the pressure that workman bears, thereby effectively promoted whole working efficiency and usage safety performance.
It possesses easy accessibility use, and once mounting is applicable advantage throughout one's life.In the complexity that greatly reduces especially mould aspect producing and making, reduce die sinking cost, significantly improving production efficiency.
