Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described, and described embodiment is only the utility model part embodiment, is not whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art, not making other embodiments used obtained under creative work prerequisite, belongs to protection domain of the present utility model.
By reference to the accompanying drawings, door lock one-way buffer device of the present utility model, comprise shell 2, described shell 2 is equipped with installing hole 1, and installing hole 1, for being connected with door lock miscellaneous part, is arranged with rotating shaft 3 in described shell 2, described rotating shaft 3 is connected with door handle 4, through hole is done in rotating shaft 3 inside, is connected in series by door lock rotational pin, realizes being synchronized with the movement with door lock handle.Cavity is formed between the outside of described rotating shaft 3 and the inside of shell 2, at least two fixed blades 5 be arranged on shell 2 are provided with in described cavity, hydraulic grease is filled with in cavity between two fixed blades 5, the excircle of described rotating shaft 3 is connected with rotating shaft sheet 9, in the cavity of described rotating shaft sheet 9 between two fixed blades 5, the outer race of described rotating shaft sheet 9 is provided with valve block 7, cavity between two adjacent fixed blades 5 is divided into two regions by described rotating shaft sheet 9 and valve block 7, i.e. cavity A6 and cavity B8, the runner 10 mutually circulated for the hydraulic grease in two regions is provided with between described rotating shaft sheet 9 and valve block 7.
As a kind of preferred mode of the utility model, in described cavity, be provided with two fixed blades 5, being arranged in cavity that rotating shaft 3 and shell 2 formed of described fixed blade 5 symmetry.
Symmetrically in described rotating shaft 3 be connected with two rotating shaft sheets 9, the periphery of each rotating shaft sheet 9 is all equipped with valve block 7.
Cavity between two adjacent fixed blades 5 is divided into two regions varied in size by described rotating shaft sheet 9 and valve block 7.
The cross section of described valve block 7 is in " recessed " shape, and valve block 7 and rotating shaft sheet 9 contact jaw offer through hole, and described through hole is communicated with runner 10.
The hole size of two foots of described valve block 7 is not identical.
The course of work of the present utility model is: when door lock resets, (counterclockwise) door handle 4 drives rotating shaft 3 and valve block 7 to be synchronized with the movement by trundle, grease in cavity A is oppressed, the grease produced in pressure is under pressure and forces valve block 7 phase countershaft 3 toward mobile in the other direction, runner is become " obstructed state ", in cavity A, hair oil fat is forced to extrude from the gap of each parts, arrives cavity B.Very large pressure is produced in this process.This pressure reacts on door handle 4, forces door handle 4 movement velocity to be fallen, thus reaches reduction of speed vibration damping and the object abated the noise.
When door lock is pressed, (clockwise) door handle 4 is synchronized with the movement by trundle rotating shaft 3 and valve block 7, grease in cavity B is oppressed, the grease produced in pressure is under pressure and forces valve block 7 phase countershaft 3 toward mobile in the other direction, runner is become " logical state ", and in cavity B, hair oil fat arrives cavity A by runner quickly through valve block.Very large pressure can not be produced in this process, thus realize one-way function.
The utility model forms by rotating shaft sheet and valve block the oily passage of mistake being used for hydraulic grease, rotating shaft sheet and valve block relative displacement can control the break-make of runner, thus the flowing velocity of hydraulic control grease in two regions, and then export different damping pressures, reach the effect of one-way buffer, and then reduce door lock vibration in use and noise.
