A kind of damping buffer
Technical field
The present invention relates to a kind of buffer, particularly relate to a kind of damping buffer.
Background technique
With lid and be more common by the product of Unscrew in the middle of life, as the storage case, electric cooker etc. of automotive interior, press the button when lid opened by needs, therefore lid can be opened by nature, and opens with natural way, and the speed opened is fast, therefore lid can strike in main body, thus easily cause lid to damage, in view of above defect, be necessary to design a kind of damping buffer in fact.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of damping buffer, solve the existing product by Unscrew lid, lid opening speed can be caused when opening lid fast, and clash into main body, thus the logical problem easily causing lid to damage.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of damping buffer, comprise housing, spring, contiguous block, base, first rubber ring, back shaft, mounting shell, foam, first setting sleeve, second setting sleeve, rubber cushion, second rubber ring, connecting head, described spring is positioned at enclosure interior, described contiguous block is positioned at spring top, described contiguous block is connected with spring close-fitting, described base is positioned at contiguous block upper end, described base is connected with contiguous block close-fitting, the first described rubber ring is between contiguous block and base, the first described rubber ring is connected with housing close-fitting with base, described back shaft is positioned at base upper end, and described back shaft runs through housing, described back shaft is connected with whorl of base, and described back shaft was connected with housing sliding joining, described mounting shell is positioned at enclosure interior, described mounting shell runs through and back shaft, and described mounting shell is positioned at base upper end, described mounting shell is connected with housing close-fitting, described foam is positioned at mounting shell inside, described foam is EVA foam, the first described setting sleeve is through back shaft, and the first described setting sleeve is positioned at foam top, the first described setting sleeve is connected with back shaft close-fitting, the second described setting sleeve is positioned at enclosure interior top, the second described setting sleeve is connected with housing close-fitting, described rubber cushion is positioned at the second setting sleeve inner bottom, described rubber cushion is connected with the second setting sleeve close-fitting, the second described rubber ring is positioned at the second setting sleeve outer wall, the second described rubber ring is connected with housing close-fitting with the second setting sleeve, connecting head is positioned at back shaft top, described connecting head is connected with back shaft screw thread.
Compared with prior art, this damping buffer, first be installed in the main body of product by housing, connecting head is installed in the cover plate of product, when the cover plate in application product is in closed condition, back shaft folds in housing, and make spring and foam be in compressive state by back shaft, when cover plate is opened, under the reaction force of spring and foam, the company's of promotion back shaft up moves, but because the first rubber ring is connected with housing close-fitting, and play seal action, therefore the first rubber ring and housing is made to there is certain frictional force, and the first rubber ring and the second rubber ring form a closed space, therefore back shaft is toward when up moving, need to overcome the frictional force of the first rubber ring and the resistance of the first rubber ring and the second rubber ring formation enclosed space, because making back shaft slowly and up ejecting swimmingly, thus reach and promote that lid is slowly stable to be opened, prevent lid from opening fast in its natural state and strike main body, thus protective action is played to application product.

Embodiment
Hereinafter, set forth multiple specific detail, to provide the thorough understanding to the concept forming described embodiment basis.But to one skilled in the art, embodiment described obviously can put into practice when not have in these specific detail some or all.In other cases, well-known treatment step is not specifically described.
As shown in Figure 1, a kind of damping buffer, comprise housing 1, spring 2, contiguous block 3, base 4, first rubber ring 5, back shaft 6, mounting shell 7, foam 8, first setting sleeve 9, second setting sleeve 10, rubber cushion 11, second rubber ring 12, connecting head 13, it is inner that described spring 2 is positioned at housing 1, described contiguous block 3 is positioned at spring 2 top, described contiguous block 3 is connected with spring 2 close-fitting, described base 4 is positioned at contiguous block 3 upper end, described base 4 is connected with contiguous block 3 close-fitting, the first described rubber ring 5 is between contiguous block 3 and base 4, the first described rubber ring 5 is connected with housing 1 close-fitting with base 4, described back shaft 6 is positioned at base 4 upper end, and described back shaft 6 runs through housing 1, described back shaft 6 is connected with base 4 screw thread, and described back shaft 6 was connected with housing 1 sliding joining, it is inner that described mounting shell 7 is positioned at housing 1, described mounting shell 7 runs through and back shaft 6, and described mounting shell 7 is positioned at base 4 upper end, described mounting shell 7 is connected with housing 1 close-fitting, it is inner that described foam 8 is positioned at mounting shell 7, described foam 8 is EVA foam, the first described setting sleeve 9 is through back shaft 6, and the first described setting sleeve 9 is positioned at foam 8 top, the first described setting sleeve 9 is connected with back shaft 7 close-fitting, the second described setting sleeve 10 is positioned at housing 1 inner tip, the second described setting sleeve 10 is connected with housing 1 close-fitting, described rubber cushion 11 is positioned at the second setting sleeve 10 inner bottom, described rubber cushion 11 is connected with the second setting sleeve 10 close-fitting, the second described rubber ring 12 is positioned at the second setting sleeve 10 outer wall, the second described rubber ring 12 is connected with housing 1 close-fitting with the second setting sleeve 11, connecting head 13 is positioned at back shaft 6 top, described connecting head 13 is connected with back shaft 7 screw thread, this damping buffer, first be installed in the main body of product by housing 1, connecting head 13 is installed in the cover plate of product, when the cover plate in application product is in closed condition, back shaft 7 folds in housing 1, and make spring 2 and foam 8 be in compressive state by back shaft 6, when cover plate is opened, under the reaction force of spring 2 and foam 8, the company's of promotion back shaft 6 up moves, but because the first rubber ring 5 is connected with housing 1 close-fitting, and play seal action, therefore the first rubber ring 5 is made to there is certain frictional force with housing 1, and the first rubber ring 5 and the second rubber ring 11 form a closed space, therefore back shaft 6 is toward when up moving, need to overcome the resistance that the frictional force of the first rubber ring 5 and the first rubber ring 5 and the second rubber ring 11 form enclosed space, because making back shaft 6 slowly and up ejecting swimmingly, thus reach and promote that lid is slowly stable to be opened, prevent lid from opening fast in its natural state and strike main body, thus protective action is played to application product, wherein contiguous block 3 plays fixation to base 4, base 4 plays support and connection function to back shaft 7, mounting shell 7 plays fixation to foam 8, first fixed cover 9 and the second fixed cover 10 play position-limiting action to back shaft 6, rubber cushion 11 plays buffer function to back shaft 6.
The present invention is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion made, all drop within protection scope of the present invention.
