Abstract

The utility model discloses an it inserts subassembly to be used for three formulas of figurative high joint degree in surface to connect, it links union piece as an organic whole and plug -in components respectively to include and have surperficial figurative article. Plug -in components include plug -in components main part and buckle, adopt evenly distributed and radian to be three formula structures of 60, and the chamfer that buckle and plug -in components main part formed is 86 (2) acute angle. The union piece is the opening and shows tubaeform hollow circular cylinder slightly, including union piece main part and draw -in groove. The hypotenuse of draw -in groove bottom plane and horn mouth becomes 86 (2) contained angles. When plug -in components get into the union piece opening, because of diminishing, the diameter is the buckle and the interlock of draw -in groove base at 86 (2) angles together with inseparable laminating of union piece and messenger. The utility model discloses the figurative rich and integrality in article surface has effectively been guaranteed, has connect simultaneously and insert the position and keep away from the outside joint edge of article that the transverse shear power that receives probably to act on the outside junction surface of surperficial article influences the minimum, is difficult for crackedly when falling. Simple to operate safety is swift, reduces working cost.

Detailed description of the invention

Below in conjunction with drawings and Examples, technology contents of the present utility model is described further.Top in the utility model, below, vertically, level etc. is the explanation carried out for accompanying drawing to the description of direction or position, but also can makes a change as required, and institute makes to change and is all included in the utility model protection domain.In addition, first, second grade of term only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.

Refer to Fig. 1 to Fig. 5, which respectively show the assembling cross-sectional view of high conjugation grade three-chip type connector assembly for molding surface of the present utility model, the perspective view of overlooking direction schematic diagram, the cross-sectional view of plug-in unit, the cross-sectional view of fitting and connector assembly of plug-in unit.

In preferred embodiment of the present utility model, as shown in Figure 1 and Figure 5, high conjugation grade three-chip type connector assembly for molding surface of the present utility model comprises plug-in unit 10 and the fitting 20 of mutual eye-splice, and described plug-in unit 10 is connected with first surface object 15 and described fitting 20 is connected with second surface object 26.Please refer to Fig. 2, plug-in unit 10 is the three-chip type structure of bottom circular, and with the center of circle of round bottom for summit, on cylinder, every 60 ° of angles are followed successively by inserted sheet and space, have three inserted sheets and three spaces; Described inserted sheet top is buckle 12, and buckle 12 bottom section thickness is plug main body 11 thickness and fitting main body 25 thickness sum.With same angle parameter, draw-in groove 21 and the fitting main body 25 of fitting 20 is set by concavo-convex corresponding method.

Please refer to Fig. 3, when making the plug-in unit 10 of the present utility model of first surface object 15 inside, the first chamfering 13 between buckle 12 and plug main body 11 is the acute angle of 86 ° (± 2 °), to ensure that the follow-up height patched engages.

Please refer to Fig. 4, when suppressing the fitting 20 of the present utility model of second surface object 26 inside, draw-in groove 21 is longer than the external diameter of plug main body 11 with the internal diameter etc. at intermediate point 22 place of lower portion, cross the second chamfering 23 that the introversion hypotenuse of intermediate point 22 and draw-in groove 21 base plane form 86 ° (± 2 °), make the fitting main body 25 in hollow cylindrical be slightly less than the external diameter of plug main body 11 at the internal diameter of draw-in groove 21 end, and the internal diameter of horn mouth 24 end is slightly larger than the external diameter of plug main body 11.First chamfering and the second chamfering can be determined flexibly according to fitting and the round diameter of plug-in unit, the material of material and processing technology.

Please refer to Fig. 1; plug-in unit 10 inserts fitting 20; after crossing fitting bottom intermediate point 22; diameter diminishes; under elastic reaction; plug-in unit 10 closely engages with fitting 20; and the first chamfering 13 being all 86 ° of (± 2 °) angles is engaged with the second chamfering 23; firm increase bond strength; play with the phase same-action of fastened by screw but not easily shirk; simultaneously can not leave installation vestige on first surface object 15, second surface object 26, available protecting rich, the integrality of object surface moulding, can not leave installation vestige at object surface.

In sum, in conjunction with the embodiment shown in above-mentioned Fig. 1 to Fig. 5, it will be appreciated by those skilled in the art that the utility model adopts three-chip type rock-steady structure, large area increases bonding area and intensity, at utmost prevents left and right displacement; For the object that volume is slightly large, more than twoly to use simultaneously, or coordinate the concavo-convex edge in object edge to use simultaneously, effect is better.Simultaneously because patching the edge that position directly connects away from first surface object 15 and second surface object 26, affect minimum by the outside cross shear that may encounter, not easily broken when falling.Meanwhile, also make easy for installation safe and efficient, reduce job costs.

The utility model is by structure influence, the reasonable scope of application is the object that inner cavity size is greater than 5mm, same material can be adopted to suppress with surperficial object simultaneously, when surperficial object is the special material outside the toughness materials such as plastics, metal and alloy, also can be used as its installation fitting, use in conjunction with other technique.

Above-mentioned embodiment is preferred implementation suggestion of the present utility model; not be used for limiting enforcement of the present utility model and interest field; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model claim.
