Abstract

The utility model relates to a buffer hinge for furniture doors comprising a main axle, a shell, an oil seal, an oil seal cap, an oil seal bottom cover, which is characterized in that one end of the main axle is arranged in the cavity of the shell and provided with an overflow plate and an oil control plate; a gap is reserved between the overflow plate and the inner wall of the cavity and the oil overflow plate provided with a boss and oil channels at one side facing the oil control plate; an seal ring is applied on the boss with a gap and the thickness of the seal ring is less than that of the boss; preformed through-holes are arranged on the control plate; the other end of the main axle passes through a stepped through-hole of the shell and the oil seal nested on the main axle is secured in the through-hole with one end stayed on the step and the other end rested on the oil seal cap fixed on the inner wall of the cavity; the oil seal cap is also jacketed on the main shaft and the oil seal bottom cover is attached on the opposite end of the through-hole of the shell. The utility model allows a silent door slamming and protects the furniture with a view to long-time service.

Description

A kind of furniture door hinge buffer

Technical field:

The utility model relates to the buffer technology field, refers in particular to a kind of furniture door hinge buffer.

Background technology:

The hinge that uses in the furniture reliably uses the bigger spring of elasticity rate in order to make a closure now, inevitably produces sharp impacts at closing time, will damage furniture in the course of time, and also can produce bigger noise at closing time.

Summary of the invention:

The utility model provides a kind of furniture door hinge buffer that is installed in the hinge at the deficiencies in the prior art.

For achieving the above object, the technical scheme that the utility model provides is: it includes main shaft, shell, oil sealing, oil seal cover and bottom, it is characterized in that: an end of main shaft places the inner chamber the inside of shell, and this end is set with overflow plate and control oiled-plate method, preset clearance between overflow plate and the inner chamber wall body, its side towards the control oiled-plate method forms boss, and form oil guide groove on this side, be with sealing ring on the boss, and leave the gap between it and the boss, the thickness of sealing ring forms through hole less than the thickness of boss on the control oiled-plate method, the other end of main shaft passes from the through hole that has step on the shell, the oil sealing that is enclosed within on the main shaft is installed in the through hole, and the one end withstands step, and the other end presets the oil seal cover that is installed in internal chamber wall, oil seal cover also is placed on the main shaft simultaneously, and the other end of relative through hole is fixed with bottom on the shell.

After adopting technique scheme; main shaft tension (state of closing the door); sealing ring relies on overflow plate; because the effect of sealing ring; the hydraulic oil oil guide groove of must flowing through, the hydraulic oil in the right chamber will flow to left chamber lentamente, and furniture door just can be closed slowly; on the contrary; main shaft pressurized (door opening state), sealing ring relies on the control oiled-plate method, the gap of the hydraulic oil flow in the left chamber between overflow plate and internal chamber wall; the through hole of the gap of sealing ring inner ring and control oiled-plate method flows back to right chamber; need not pass through oil guide groove, the flow velocity of hydraulic oil can be faster than at closing time, thus the speed that not overslaugh is opened the door; the utlity model has the peace and quiet of closing the door; effectively protection furniture prolongs the furniture characteristic in application life.

Description of drawings:

Accompanying drawing 1 is the structural representation of door opening state main shaft pressurized of the present utility model;

Accompanying drawing 2 is the structural representation of the state main shaft tension of closing the door of the present utility model;

Accompanying drawing 3 is faced structure chart for overflow plate of the present utility model;

Accompanying drawing 4 is A-A sectional structure charts of Fig. 3.

Specific embodiment:

Now elaborate preferred embodiment of the present utility model in conjunction with the accompanying drawings,

The hinge buffer of this preferred embodiment, see Fig. 1～shown in Figure 4, one end of its main shaft 1 places the inner chamber of shell 2, and this end is set with overflow plate 3 and has the control oiled-plate method 4 of through hole 10, overflow plate 3 forms a circumference oil guide groove 7 towards a side of control oiled-plate method 4, this side also forms boss 6, and sealing ring 8 is set on this boss 6, and leaves gap 9 between them; The other end of main shaft 1 passes from the through hole that has step 11 on the shell 2, the oil sealing 12 that is enclosed within on the main shaft 1 is installed in the through hole 11, the one end withstands step, the other end presets the oil seal cover 13 that is installed in internal chamber wall, oil seal cover 13 also is placed on the main shaft 1 simultaneously, and the other end of relative through hole 11 is fixed with bottom 14 on the shell 2.See shown in Figure 2, when pulling main shaft 1, sealing ring 8 is close to overflow plate 3, and this gap 9 communicates with oil guide groove 7, the thickness of sealing ring 8 is less than the thickness of boss 6, it can be moved between overflow plate 3 and control oiled-plate method 4, and preset clearance 5 between overflow plate 3 and the internal chamber wall, when sealing ring 8 is close to overflow plate 3, hydraulic oil is flow through from oil guide groove 7 by its effect, the thereby therefore flow velocity of control hydraulic oil needs just stretchy main shaft 1 of bigger power, thereby the purpose that realization is slowly closed the door.See shown in Figure 1, when opening the door, main shaft 1 pressurized, sealing ring 8 is close to control oiled-plate method 4, lose sealing function, the hydraulic oil directly gap 5 between gap 9, overflow plate 3 and internal chamber wall between through hole 10, sealing ring 8 and the boss 6 of control oiled-plate method 4 flows through, and no longer is subjected to the control of oil guide groove 7, thus the purpose that realization is opened the door rapidly.
