One of the utility model major character promptly is to have can prevent that chemical glue from producing and dash the action of penetrating cruelly, that is the utility model is provided with second end connector 5 of a safeguarding mechanism at least on serial connection flexible pipe 4, that is person as shown in Figure 4; The safeguarding mechanism of second end connector 5 has a cylindrical upper shield 6 can be simultaneously with reference to figure 5; The one of which end is open opening 60, is provided with the two symmetric mouths 64 of wearing on the upper shield 6 of nearly opening 60 ends in addition, and upper shield 6 inwalls in opening 60 are formed with an inner room 63; One end of this inner room 63 holds formed consent 61 to be connected with upper shield 6 in addition; Have female thread 610 in consent 61 inner circle walls, and the interior bore of inner room 63 being greater than the interior bore of consent 61, is to form a stepped bulge loop wall 62 between the two.One cylindrical base 7 can be with reference to 6 and Fig. 7; This pedestal 7 has a cylindrical chamber 70; Convex with a plurality of spaced fins 712 on its inner circle wall; And each fin 712 down extends on the set platform 710 of the oblique cone wall 71 of cylindrical chamber 70 inner bottom parts, and between two platforms 710 and form a sagged shape circulation groove 711, and the ring side has the conflict face 713 of an arcuation in each platform 710.On the periphery wall of the pedestal 7 of cylindrical chamber 70 bottoms, be provided with an annular groove 72 in addition, extend one by annular groove 72 and possess stair-stepping connecting end 73, also be formed with the passage 74 that is connected with cylindrical chamber 70 in connecting end 73 inside.One seal ring 53 can be sheathed on the annular groove 72 of aforementioned pedestal 7; One cushion pad 51 which is provided with a roof limb wall 511, and this roof limb wall 511 can be butted between the bulge loop wall 62 and pedestal 7 of aforementioned upper shield 6, and has the communication port 510 that penetrates fully on the cushion pad 51, and is as shown in Figure 4.One bibcock 8 can be simultaneously with reference to figure 8; This bibcock 8 is that plastic material is made; The one of which end is one to be the cylinder 81 of suitable length, in the other end be provided with one can with the inaccessible termination 82 of resisting on the conflict face 713 of aforementioned cylindrical chamber 70, and be provided with a protruding wall 83 between cylinder 81 and the inaccessible termination 82.Aforementioned bibcock 8 is formed with a plurality of spaced fins 84 on the cylinder that approaches external end head 811 81; Between two fins 84, form the circulation groove 85 of a sagged shape; And for the jack-post tip 90 that prevents valve 9 touch can cause when the bibcock 8 bibcock 8 to produce wearing and tearing can be with reference to Figure 10; Thereby on external end head 811, be provided with an axis hole 810, and it is locked and is provided with the made plug of a metal material 812, and it can touch Shi Buhui at the jack-post tip 90 of valve 9 mutually and produce abrasion.One spring 52 can be sheathed between peripheral and fin 712 inside casings that be arranged on the cylindrical chamber 70 of pedestal 7 in the inaccessible termination 82 of aforementioned bibcock 8 enclose, and spring 52 1 ends are butted on the protruding wall 83, and the other end contacts at can be with reference to figure 4 and shown in Figure 9 on the platform 710.The upper shield that is combined with cushion pad 51 6 covers are overlying on aforementioned pedestal 7 peripheries that have been provided with the bibcock 8 of spring 52; Let pedestal 7 penetrate and be positioned at inner room 63 by opening 60; And aforementioned protruding wall 83 1 sides can be butted on cushion pad 51; Communication port on the cushion pad 51 510 is closed, and the cylinder 81 of bibcock 8, a plurality of fin 84 and circulation groove 85 can be extended through the communication port 510 on the cushion pad 51.The buckling sheet 54 of one link spring shape can overlap the peripheral of the connecting end 73 that is overlying on pedestal 7 and get in the aforementioned upper shield 6 and enclose, by the clamp piece 541 with elasticity and evagination be fastened on upper shield 6 wear mouthfuls 64 sentence form fixing.One C type clasp 55 can overlap periphery and buckling sheet 54 rears of the connecting end 73 that is overlying on pedestal 7 and get in the aforementioned upper shield 6 and enclose; And can be fastened on wearing of upper shield 6 in the flank 551 of C type clasp 55 outsides protrusions and mouthfuls 64 sentence and form fixingly, it can let buckling sheet 54 be fixed in more in pedestal 7 and the upper shield 6 to enclose.A but end of aforementioned pedestal 7 noose serial connection flexible pipe 4 on the connecting end that exposes outside upper shield 6 73; Can will be connected in series flexible pipe 4 by a retaining ring 40 is completely fixed with second end connector 5 and combines; The consent 61 of the upper shield 6 of second end connector 5 then is provided with a plug part 50, and is as shown in Figure 9.Though connecting end 73 the two combination that fasten of serial connection flexible pipe 4 and pedestal 7; Because after buckling sheet 54 is fastened in upper shield 6; The inner diameter volume of buckling sheet 54 is greater than the outer bore of the connecting end 73 of pedestal 7 but less than the outer girth diameter of position at the pedestal 7 of 70 sections of cylindrical chamber; Except not causing pedestal 7 to come off the upper shield 6; Can be when screwing togather when utilizing upper shield 6 and valve 9 to be rotated with reference to shown in Figure 10, the bibcock of being fixed in upper shield 6 and the upper shield 6 thereof 8 can rotate freely and can not cause serial connection flexible pipe 4 to produce the phenomenon of reeling synchronously, and is quite convenient in the use.Please refer to Fig. 9 and Figure 10; Under the state of second end connector 5 shown in Figure 9; No matter be that the switch 11 of machine box body 1 is in On and chemical glue is compeled to squeeze under the state that flows by air pressure,, the communication port on the cushion pad 51 510 is closed because the protruding wall 83 of bibcock 8 can fully closely be contacted with aforementioned cushion pad 51; Let the chemical glue of circulation also can't pass through communication port 510, form the protection mechanism that can prevent that chemical glue from dashing cruelly.When the user takes away the plug spare 50 on the consent 61 of second end connector 5; And be screwed together in the external screw thread 92 on the valve 9 of automobile tire 99 fully by the female threads 610 in the consent 61; Please refer to Figure 10; Because the plug 812 on the external end head 811 of bibcock 8 receives the effect of touching of the jack-post tip 90 of valve 9; Bibcock 8 pressure spring 52 that moves to right leaves the cushion pad 51 that is originally blocked contact to cause protruding wall 83, and communication port 510 forms negotiable channel status, this moment by the chemical glue that air promoted can get into via the passage 74 of pedestal 7 cylindrical chamber 70 interior and lasting via circulation groove 711, be positioned at the bibcock 8 of communication port 510 circulation groove 85 can be with reference to shown in Figure 8 and consent 61; Get in the worn tire 99 via the passage 91 of valve 9 more at last; So can reach encapsulating and get into the action of carrying out tire patching in the tire 99, certainly, be inflated to till the normal tire pressure in the flat tire 99 of the still sustainable entering of pressurized air.

Take a broad view of preceding opinion; The utility model provides a kind of joint structure that serial connection can be mended the vehicle mounted air compressor 13 of glue and inflation on the flexible pipe 4 to worn tire 99 that is positioned at, and it has and prevents that the user from causing chemical glue that sudden and violent disappearance of dashing ejaculation takes place following of incorrect operating procedure.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
