Embodiment
Below in the explanation to handle box embodiment of the present invention, the structure identical with known handle box repeats no more, only to being illustrated with the closely-related structure division of the present invention.
As Fig. 7, Fig. 8 and shown in Figure 9, be provided with stair-stepping through hole 80 at two sidewalls 701 of the Delevoping cartridge box body 70 of handle box and the intersection of diapire 702.Through hole 80 is made up of groove 81 and the through hole 82 that forms at the bottom centre of groove 81 place, and the opening of groove 81 is towards lateral end seal part 20 and low end seal 30, and its cross-sectional area is greater than the cross-sectional area of through hole 82.Through hole 80 and the goo that is filled in the through hole 80 have constituted adhering device.Goo should have good springiness, and the characteristics that viscosity is strong can be foamed glue, white glues or sealing glue.
Goo can be filled with the following methods, before installation side end seal 20 and low end seal 30, be filled in the groove 81, also can be after installing lateral end seal part 20 and low end seal 30, be expelled to the groove 81 by through hole 82 from the outside of box body 70.Because the cross-sectional area of groove 81 is far longer than the cross-sectional area of through hole 82, after goo is filled in the groove 81, can in groove 81, spreads, and remain in the groove 81.In order to prevent that goo from flowing out from through hole 82, can design through hole 82 enough for a short time, for example, can be arranged to the area of through hole 82 only can be by the size of injection goo syringe needle; Perhaps at the arranged outside seal or the plug of through hole 82.
When lateral end seal part 20 and low end seal 30 are pasted respectively on sidewall 701 and diapire 702 by double faced adhesive tape usually, and overlap in the intersection of sidewall 701 and diapire 702.The adhering device that is provided with in intersection, a part that makes lateral end seal part 20 and low end seal 30 all contacts with goo in the adhering device, because goo has elasticity and viscosity is stronger in the adhering device, can offside end seal 20 and low end seal 30 apply an extra viscous force, they tightly are bonded on the box body 70, thereby prevent that lateral end seal part 20 and low end seal 30 are in intersection's perk of coming unstuck.
Shown in Figure 10 (1), Figure 10 (2), Figure 10 (3) and figure (4), can there be various embodiments the position between lateral end seal part 20, low end seal 30 and the adhering device.Among the embodiment that Figure 10 (1) shows, low end seal 30 covers on the lateral end seal part 20, they overlap at the sidewall of Delevoping cartridge box body and the intersection of diapire (not shown), through hole 80 also is arranged on the intersection of sidewall and diapire, covered fully by lateral end seal part 20 and low end seal 30, in this case, the part of lateral end seal part 20 and low end seal 30 all can contact with the goo in the through hole 80.Among the embodiment that Figure 10 (2) shows, lateral end seal part 20 and low end seal 30 do not have lap, but cross in the intersection of sidewall and low wall, and there is a gap, at this moment, through hole 80 is arranged on the intersection of sidewall and low wall, and its first half is covered by lateral end seal part 20, and the latter half is covered by low end seal 30.Among the embodiment shown in Figure 10 (3), low end seal 30 covers on the lateral end seal part 20, they overlap at the sidewall of Delevoping cartridge box body and the intersection of diapire, through hole 80 also is arranged on the intersection of sidewall and diapire, but not all to be covered by lateral end seal part 20 and low end seal 30, and just some is covered by lateral end seal part 20 and low end seal 30 respectively, and its goo all has with lateral end seal part 20 and contacts with low end seal 30.Among the embodiment shown in Figure 10 (4), low end seal 30 covers on the lateral end seal part 20, but they are not the intersection's overlappings at the sidewall of Delevoping cartridge box body and diapire, but overlap in other parts of box body, in other embodiments, also can cross, at this moment, through hole 80 is not arranged on the intersection of sidewall and diapire, and is arranged on the overlapping place or the intersection of box body upside seal 20 and low end seal 30; At this moment, through hole 80 is covered fully by lateral end seal part 20 and low end seal 30, and its part contacts with lateral end seal part 20, and another part contacts with low end seal 30.
Among the above-mentioned various embodiment, all satisfy following condition, being lateral end seal part 20 all contacts with at least a portion of goo in the through hole 80 with low end seal 30, therefore, through hole 80 should be arranged on the lateral end seal part 20 on the box body and the intersection or the overlapping place of low end seal 30, rather than the intersection of sidewall and diapire must be set, only when lateral end seal part 20 and low end seal 30 crossed or be overlapping in the intersection of sidewall and diapire, through hole 80 just was arranged on the intersection of sidewall and diapire.
In other embodiments, adhering device can also be made up of clear opening on the box body and the goo that is filled in wherein, at this moment, can increase seal or plug in the outside of clear opening and prevent that goo from flowing out.Adhering device also can be made up of groove on the box body and the goo that is filled in wherein, and at this moment, the filling mode of goo has only a kind of, promptly just fills goo before installation side end seal and low end seal in groove.
More than be to embodiments of the invention and the explanation carried out around the dependency structure conversion of embodiment.But the present invention is not limited to technique scheme, and for example, the quantity of the adhering device of the every side of Delevoping cartridge box body of handle box can be a plurality of, and the shape of through hole also can be square etc.These changes and equivalent transformation all should be included within the described scope of claim.
