Description
Technical field
The utility model relates to the mechanical component field, particularly a kind of leakage proof blind hole double-screw bolt.
Background technique
Double-screw bolt is a kind of mechanical component that is used to assemble, and can be fixed on the object through welding or riveted way.Along with automobile waterproof sealing performance demands is improved gradually; Simultaneously the light-weighted requirement of automobile is also day by day strengthened; Top cover, back wall positions such as (cargo vehicles) on the automobile all is the single layer board structure that adopts basically at present, through its inner parts such as buttress brace head cover plate, squab panel (cargo vehicle) supported to guarantee its structural strength.Owing to need add component in automobile top-cap, back wall (cargo vehicle) outside; In order to guarantee the vehicle body outward appearance; What generally adopt is the position welding projection welding nut that adds component at needs; The component that install additional then are installed on top cover or the back wall (cargo vehicle) through bolt, and its sealing then is to wait and guarantee through between component and body panel, installing sealing gasket additional.
In the process that realizes the utility model; The inventor finds that there is following problem at least in existing technology: add component through adopting project-welding nut and bolt; Need to adopt the sealing gasket sealing; Because sealing gasket is provided with the via hole of bolt, rainwater infiltrates sweep inside through the screw thread of bolt, can cause seepage.And the component that install additional directly contact with vehicle-body outer panel, are prone to the finish paint that collides with, and influence the vehicle body outward appearance.
The model utility content
Existing add the problem that the seepage that component causes and the component that install additional and vehicle-body outer panel directly contact the finish paint that is prone to collide with through project-welding nut and bolt in order to overcome, the utility model embodiment provides a kind of leakage proof blind hole double-screw bolt.Said technological scheme is following:
A kind of leakage proof blind hole double-screw bolt comprises top cover and cylinder, and said top cover is on said cylinder top, and the cylinder middle part axially offers blind hole along said cylinder, and the opening of said blind hole is located on the said top cover.
Further, the bottom end that said top cover is connected with said cylinder is provided with the groove around said one week of cylinder, and the side of said top cover has the hole, and said hole is communicated with said groove.
Alternatively, be provided with internal thread in the said blind hole of said cylinder away from an end of said top cover.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is: the direction through the said cylinder on the edge, middle part of common double-screw bolt offers blind hole; The part that the outside installs additional is installed on the vehicle-body outer panel through blind hole, makes the rainwater that infiltrates from component can not leak into vehicle-body outer panel.And the bottom end of the leakage proof blind hole double-screw bolt of the utility model is provided with around cylinder one groove in week, and the hole of opening through the top cover side forms seal ring to the groove encapsulating, has avoided rainwater to infiltrate from end cap, thereby has solved leakage problems.Accompany top cover between component that install additional and the vehicle-body outer panel, avoided the outside part that installs additional to contact, solved the problem of the finish paint that collides with the direct of vehicle-body outer panel.The utility model is simple in structure, and is easy for installation.
Description of drawings
In order to be illustrated more clearly in the technological scheme among the utility model embodiment; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the leakage proof blind hole double-screw bolt that provides among the utility model embodiment 1;
Fig. 2 is the schematic cross-section of the leakage proof blind hole double-screw bolt that provides among the utility model embodiment 1.
In the accompanying drawing, the component list of each label representative is following:
1 top cover; 2 cylinders; 3 blind holes; 4 stiffening plates; 5 vehicle-body outer panel; 6 grooves; 7 holes.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model mode of execution is done to describe in detail further below.
The utility model embodiment provides a kind of leakage proof blind hole double-screw bolt; As depicted in figs. 1 and 2; This leakage proof blind hole double-screw bolt comprises: top cover 1 and cylinder 2 also comprise: in top cover 1 and the blind hole axially offered 3 of cylinder 2 middle parts along cylinder 2, the opening of blind hole 3 is located on the top cover 1.
Further, the bottom end that top cover 1 is connected with cylinder 2 is provided with around the cylinder groove 6 in 2 one weeks, and the side of top cover 1 has hole 7, and this hole 7 is communicated with groove 6.Know that easily hole 7 also can be opened on the top end of top cover 1.
Alternatively, be provided with internal thread in the blind hole 3 of cylinder 2 away from an end of top cover 1.
The application process of the leakage proof blind hole double-screw bolt of present embodiment is described below in conjunction with Fig. 1 and Fig. 2.
When leakage proof blind hole double-screw bolt is installed, stiffening plate 4 and vehicle-body outer panel 5 are welded through technologies such as spot welding, offer the corresponding hole of using at the position that needs add component then; Corresponding with the degree of depth in hole with the length of the needed bolt of component that installs additional, then with leakage proof blind hole double-screw bolt along being welded in week on the vehicle-body outer panel, during welding; The hole 7 of opening from top cover 1 side is to groove 6 encapsulatings; Through to welding assembly stoving of the paint, the sealer that is poured into is cured then, thereby realizes sealing.Be installed to the component that install additional on the vehicle-body outer panel through blind hole 3 then.
