Specific implementation mode

For the ease of understanding the utility model, in the following with reference to the drawings and specific embodiments, the utility model is carried out more detailed Thin explanation.

It should be noted that when element is referred to as " connecting " another element, it can be directly to another yuan Part may be simultaneously present centering elements；Term used in this specification " fixation ", " connection ", "front", "rear", " left side ", " right side ", "top", "bottom" and similar statement are for illustrative purposes only；Term "and/or" used in this specification includes Any and all combinations of one or more relevant Listed Items；First, second is intended merely to used in the utility model Facilitate number and is arranged.

As shown in figures 1 to 6, a kind of leak sealing device for adhesive hose, including glue-spreading head 10 and head cover 20, the plastic emitting First 10 and head cover 20 be detachably socketed；Glue-spreading head 10 includes front end 11 and rear end 12, and rear end 12 is used for soft with adhesive Pipe is detachably connected, and an inner cavity is formed between front end 11 and rear end 12, and the top center of front end 11 is provided with one and plastic emitting The connection of head inner cavity goes out sebific duct 13, and the glue squeezed out from adhesive hose flows through the inner cavity of glue-spreading head 10, is flowed from sebific duct 13 is gone out Go out.

Head cover 20 for covering glue-spreading head 10 includes a sealed groove 21 for being fixed on 20 inside top center of head cover, should The opening of sealed groove 21 and the opening of head cover 20 are arranged in the same direction, and a sealing bar 22 is provided at the center of sealed groove 21, should Sealing bar 22 is extended outside sealed groove 21, it is preferable that the sealing bar 22 is extended except head cover 20.

When head cover 20 and glue-spreading head 10 are mutually socketed, sealing bar 22 is inserted into out sebific duct 13, and it is recessed to go out the insertion sealing of sebific duct 13 Slot 21；Sealing bar 22 and the inner surface dynamic sealing for going out sebific duct 13 coordinate, sealed groove 21 and the outer surface dynamic sealing for going out sebific duct 13 Cooperation.

The diameter of sealing bar 22 is slightly less than 13 internal diameter of sebific duct, and sealing bar 22 is enable smoothly to be inserted into out in sebific duct 13, compels It uses the glue in sebific duct 13 to flow back in adhesive hose, and is not easy to flow out, reach sealing effect.

Various shapes can be arranged in the inner surface of sealed groove 21, such as cone or cylindrical.In the present embodiment, sealed groove 21 inner surface is cylindrical, and the spacing of 21 inner surface of sealed groove and 22 outer surface of sealing bar is slightly larger than the wall of sebific duct 13 Thickness, so that when sealing bar 22 is inserted into glue-spreading head 10, going out sebific duct 13 can smoothly be inserted into sealed groove 21, and reach sealing Effect；

When the inner surface of sealed groove 21 is cone, the diameter of the cone gradually becomes along 20 opening direction of head cover Greatly, and maximum gauge is more than the outer diameter of sebific duct 13, and when glue-spreading head 10 and head cover 20 are socketed, sealing bar 22 is inserted into out sebific duct 13 It is interior, while going out the inner surface that 13 distal outer surface of sebific duct is connected to sealed groove 21, prevent extraneous air or steam from entering plastic emitting In pipe 13, reach sealing effect.

In the present embodiment, the apical lateral for going out sebific duct 13 is cylinder；Further, go out the apical lateral of sebific duct 13 in circle Taper can be bonded to each other with the conical inner surface of sealed groove.

In the present embodiment, head cover outer surface is generally conical, and the top outer of head cover 20 is a flat surface, and is packing When, the contact area with packing case can be increased, avoid single-contact and squeeze pressure is excessive, cause the breakage of packing case, side Just it transports.

The side of head cover 20 is arranged at intervals with several grooves conveniently turned；Preferably, it is arranged on groove several along top The anti-sliding burr that 20 side of lid is obliquely installed.

The open at one end of head cover 20 is provided with internal thread in the present embodiment, 10 front end of glue-spreading head is provided with external screw thread, top Lid 20 is connected through a screw thread with 10 front end of glue-spreading head；Or head cover 20 is detachably connected by buckle with glue-spreading head 10.

The rear end of glue-spreading head 10 is provided with external screw thread, is connected through a screw thread with adhesive hose；The rear end of glue-spreading head 10 The cross section of side is more prismatics, is conveniently turned.

This goes out sebific duct 13 and sealing bar can be used the metals such as plastics or copper, iron and be prepared.

The utility model is described above in association with preferred embodiment, but the utility model is not limited to above take off The embodiment shown, and modification, equivalent combinations that various essence according to the present utility model carry out should be covered.
