Abstract
The utility model relates to an improved damping device, which comprises a shell, a shaft core, a unidirectional element and damping oil. The unidirectional element is changed into an isosceles triangle the cross section of which is inverted; the unidirectional element is comparatively stout and is not easy to rupture when immersion oil swells; the middle position of the side slot wall of a V-shaped slot for accommodating the unidirectional element is inwards provided with a transversal straight cut making the inside and the outside of the slot communicated from a top end, and the other side slot wall thereof is provided with a sunken step towards the middle position of one surface of the unidirectional element. As an oil flowing passage, the structure is beneficial to the running of the damping oil, and the improved unidirectional element can prolong the service life of the improved damping device.
Description
Technical field
The utility model relates to a kind of damping unit, particularly the groove of its unidirectional element and ccontaining unidirectional element has been made improved damping unit.
Background technology
Damping unit is used on the toilet lid, when toilet lid is started, does not play damping action, in the process that toilet lid is covered, produces damping action.In the existing damping unit, used unidirectional element, there are T shape, V-arrangement or other shapes in its cross section, and what have also offers oil-through hole on unidirectional element, and generally speaking, unidirectional element is thiner.Unidirectional element plays the one-way check effect as the oil circuit switch to damping oil, thereby realizes unidirectional damping.Spend when oil, unidirectional element can expand, repeatedly oily excessively, and thin unidirectional element fractures easily, and unidirectional damping is failed.
Summary of the invention
The purpose of this utility model is that a kind of improved damping unit will be provided, and the groove of unidirectional element and ccontaining unidirectional element is improved, damping unit more is tending towards rationally, light undamped when lavatory lid is opened, and when closing, damping is better, and has long application life.
The utility model is to realize like this, described a kind of improved damping unit, it comprises housing, the axle core, unidirectional element and damping oil, extension is provided with two barricades to housing to the center by the inwall one, the outer wall of axle core is resisted against the top of two barricades of housing, the inside one of axle core is extended two convex tendons that are provided with symmetry, be provided with the groove of ccontaining unidirectional element on each convex tendon along the axis direction of axle core, unidirectional element is movably placed in this groove, and freely open and withstand between inner walls and the bottom land, between the cell wall of unidirectional element and groove, be provided with can make unidirectional element in groove along gap that the circumferencial direction of axle moves; Cell wall is provided with otch, unidirectional element is combined together with housing hermetically with coaxial core, damping oil is filled in the interior remaining space of housing of sealing, it is characterized in that: the isosceles triangle of the cross section of described unidirectional element for standing upside down, and end face forms the arc that cooperates with inner walls; The slot cross-section of described ccontaining unidirectional element is a V-shaped groove, centre position on the one side channel wall of V-shaped groove is offered one inwards by the top and is made the horizontal straight cut that is interlinked to the outside in the groove, the centre position towards the one side of unidirectional element of opposite side cell wall is provided with a step that sink, as crossing oily passage.
The bottom of V-shaped groove described in the utility model has circular arc; The cross section is the unidirectional element of the isosceles triangle of handstand, and its bottom also is the circular arc that cooperates with the V-shaped groove bottom.
The beneficial effects of the utility model are, change unidirectional element the isosceles triangle of cross section for standing upside down into, and unidirectional element is more solid, the immersion oil not easy fracture that expands; The V-shaped groove of ccontaining unidirectional element, centre position on the one side channel wall is offered one inwards by the top and is made the horizontal straight cut that is interlinked to the outside in the groove, the centre position towards the one side of unidirectional element of opposite side cell wall is provided with a step that sink, as crossing oily passage, this structure helps the operation of damping oil, can prolong the application life of damping unidirectional element.
