Background technology
The existing use in refrigerator doors, the door in fields such as toilet lid, the rotary buffer of the prolongation closing time that install at the rotary gemel place between lid and the body, comprise following, with following rotating shaft that is tightly connected, described rotating shaft comprises the connector and following buffer that is tightly connected on top, described buffer comprises diaphragm seal, with the close-connected axle of connector core, be symmetrically arranged with a pair of axle ear on the periphery of described axle core both sides, all be socketed with the valve card that is provided with valve on this ear, be arranged with valve block in this valve card, in actual use, can realize cushioning effect preferably, avoid door, the rigid shock of lid and body has prolonged door, the application life of lid, but also there are some shortcomings simultaneously, such as, the anti-stamping press of axle ear is relatively poor, is thrust easily; A little less than the valve card is extremely thin, break easily; The insufficient strength of rotating shaft self is also twisted off easily.Therefore, be necessary the prior art is improved, to improve the quality and the application life of snubber.
The utility model content
The purpose of this utility model is, overcomes the above-mentioned defective of prior art, provides a kind of heavy type that is used for to renovate product, requires long service life, the high strength rotary buffer that anti-pressure ability is strong.
For realizing described purpose, the technical scheme that the utility model provides is as follows: construct a kind of high strength rotary buffer, comprise following, rotating shaft with following sealing assembling, described rotating shaft comprises the connector on top and the buffer of following sealing assembling, described buffer comprises diaphragm seal, with the close-connected axle of connector core, balance is provided with a pair of valve card on the periphery of described axle core both sides, be provided with the valve groove between this valve card and the axle core periphery, described rotating shaft middle part offers one and inlays the blind groove of strengthening axle, this inlays the reinforcement axle that closely is inlaid with corresponding with it raising rotating shaft intensity in the blind groove of strengthening axle, described reinforcement axle adopts metal material or plastic shaping, the described cross section shape of strengthening axle is designed to help improving the torsional strength and the flexural strength of rotating shaft, and this cross section shape can be a spline-shaped, triangle tooth shape, polygon, or the like the shape of non-circle; A described rotating shaft each several part and a reinforcement axle integrated injection molding.
Offer the valve block hole of a pair of balance in the middle part of described this center of circle face to the valve card of balance setting, described valve block is plugged with corresponding valve block in the hole, and the material of described valve block can be metal material or composite material.
Described this all established a pair of monolateral valve port to valve card and the tight junction of axle core, and described monolateral valve port place is connected with the corresponding valve block of a shape, and the material of described valve block can be metal material or composite material.
Described axle core middle part also offers the bypass channel that is used to control closing speed.
Described following and rotating shaft buffer sealing assembling are filled with the resistance medium in the sealing space, this resistance medium comprises the corresponding filler of resistance oil, resistance fat, resistance cream or the like.
The utility model is that operating principle is: following with the sealing assembling of rotating shaft buffer after, ready-made four cavitys in sealed space, the demarcation strip of wherein following original two symmetries will be evenly divided into two fixing cavitys in the sealing device, and the valve of symmetry is divided into two less movable cavitys respectively with two cavitys on the buffer, when opening door or lid be, resistance medium in the buffer flows into from the front of valve, flow into the movable cavity at another back side from a movable cavity in front, very smooth and easy, can not produce obstruction; When door close or lid, resistance medium in the buffer is flowed into by the back side of valve, promptly flow into the movable cavity in another front from a back side activity cavity, because liquid medium is tightly oppressed valve by the back side and is caused liquid medium smooth and easyly to flow, liquid medium can only slowly flow to positive movable cavity by bypass channel or valve periphery fine gap, therefore make the closing velocity that is attached thereto the door that connects or lid be obstructed and reduce, reach the effect of door close or lid buffering, prolonged the application life of door or lid effectively.
The beneficial effects of the utility model are, the reinforcement axle of integrated injection molding and valve card, increased the intensity of rotating shaft, solved the low short problem of its life-span that causes of prior art shaft intensity, promoted rotating shaft mass, optimize the quality of snubber, made this high strength rotary buffer to be advantageously applied in every Related product more.
