Description
Technical field
The utility model belongs to the technical field of hinge, in particular to a kind of buffer hinge.
Background technique
Hinge is usually used in connecting two objects, rotates two objects mutually；It is gentle that hinge can be divided into common hinge
Rush hinge, common hinge does not have a pooling feature, and buffer hinge is widely used in due to it with preferable buffer capacity
On cabinet, for working as a buffer when opening or closing cabinet, cabinet door and cabinet body impact force is avoided to spend big and damage cabinet.
However, the buffer that existing buffer hinge uses is expensive, processing cost is high, and is easily damaged, and limits
The application range of buffer hinge.
Utility model content
Based on this, the purpose of this utility model is to provide a kind of buffer hinges, it is intended to solve existing buffer hinge at
This height and the technical issues of be easily damaged.
The utility model is realized in this way providing a kind of buffer hinge, it is pivotally connected including fixed arm, with the fixed arm
Swing arm and shrinkable and extensible ripple air buffer；Ripple air buffer one end connects the fixed arm, separately
One end connects the swing arm；The ripple air buffer is equipped with inner cavity, and the inner cavity is equipped with the first opening；The inner cavity setting
To be expanded in the stretching, extension of ripple air buffer, reduced when ripple air buffer is shunk.
Further, the inner cavity is additionally provided with the second opening, and second opening is equipped with one-way cock, the check valve
Door is breather check valve door.
Further, second opening is set to one end that ripple air buffer connects the swing arm.

It is connected on another component.The orientation or positional relationship of the instructions such as term " on ", "lower", "left", "right" is based on attached drawing
Shown in orientation or positional relationship, be merely for convenience of describing, rather than the device or element of indication or suggestion meaning must have
There is specific orientation, be constructed and operated in a specific orientation, therefore should not be understood as the limitation to this patent.Term " first ",
" second " is used merely to facilitate description purpose, is not understood to indicate or imply relative importance or implicitly indicates technical characteristic
Quantity.The meaning of " plurality " is two or more, unless otherwise specifically defined.
Referring to Fig. 1, providing a kind of buffer hinge, including fixed arm 1, the swing arm 2 being pivotally connected with the fixed arm 1 and can receive
Contracting and extensible ripple air buffer 3；Described 3 one end of ripple air buffer connects the fixed arm 1, other end connection
The swing arm 2；The ripple air buffer 3 is equipped with inner cavity, and the inner cavity is equipped with the first opening 31；The inner cavity is set as
Ripple air buffer 3 expands when stretching, and reduces when ripple air buffer 3 is shunk.
In above scheme, when the rotation of swing arm 2 opens buffer hinge, ripple air buffer 3 is in extended state, at this time
Since the stretching, extension of ripple air buffer 3 causes the pressure of inner cavity subatmospheric, enter air in inner cavity from the first opening 31,
Ripple air buffer 3 slowly stretches, and plays the role of buffering；When buffer hinge is closed, ripple air buffer 3 is shunk,
The gas of inner cavity pressure due to being squeezed is greater than atmospheric pressure, and the air of inner cavity is discharged slowly by the first opening 31, thus
Reach buffering effect.Not only buffering effect is good for the utility model, but also structure is simple, and processing cost is low
Further, the inner cavity is additionally provided with the second opening 32, and second opening 32 is equipped with one-way cock 33, described
One-way cock 33 is breather check valve door 33.It is slow due to needing to open using biggish strength when avoiding using buffer hinge
Hinge is rushed, is made troubles to user, therefore, one-way cock 33 is arranged by the second opening 32 of setting in this programme, so that
When opening buffer hinge, air can enter inner cavity from the first opening 31, can also be entered in inner cavity by the second opening 32,
The inflow velocity of air is accelerated, user can use lesser strength, that is, openable buffer hinge；And closing buffering hinge
It when chain, is set to the one-way cock 33 at the second opening 32 and closes, slow down the speed of air outflow, obtain preferable buffering effect
Fruit；Therefore, when by the resulting buffer hinge of the present embodiment be applied to cabinet on when, can be convenient for people to use and
Preferable buffering effect.
Further, second opening 32 is set to one end that ripple air buffer 3 connects the swing arm 2.It is answering
When with buffer hinge, fixed arm 1 is generally in stationary state, and swing arm 2 is rotated around fixed arm 1 during use；Cause
Second opening 32, is set to one end of swing arm 2 by this, and the response speed of one-way cock 33 can be improved, and then improves buffering hinge
The buffer capacity of chain and more convenient people operation.
Further, first opening 31 is set to the ripple air buffer 3 connects the fixed arm 1 one
End.In the present solution, the first opening 31, far from swing arm 2, the path longest that the air in inner cavity passes through in discharge, compression ratio is most
Greatly, the air pressure for improving inner cavity keeps the effect of ripple air buffer 3 more preferable.To keep shown ripple air buffer 3 more flat
It quietly works as a buffer, multiple first openings 31 can be opened up, and multiple first openings 31 are arranged along the circumferential direction of air buffer
Column.
Further, the fixed arm 1 is equipped with groove 11, and the ripple air buffer 3 is connected to 11 bottom of groove.It is logical
Setting groove 11 is crossed, when closing buffer hinge, ripple air buffer 3 is contained in groove 11, compact-sized, and will not be by
In the rotation angle for limiting swing arm 2 and fixed arm 1 provided with ripple buffer.
Further, the ripple air buffer 3 is connected with hook 34, and swing arm 2 is equipped with the card to match with hook 34
Slot 21, ripple air buffer 3 pass through the 34 connection swing arm 2 of hook.The connection side matched using hook 34 with card slot 21
Formula, structure is simple, easy for installation and stable connection.
Further, the ripple air buffer 3 is fixedly connected with the fixed arm 1 by buckle or glue.This programme
Rapidly ripple air buffer 3 can be connected on fixed arm 1.
It further, is more convenient connection, 3 both ends of ripple air buffer are connected with sheet metal 35, the ripple
Air buffer 3 connects the fixed arm 1 and swing arm 2 by sheet metal 35；Pass through the connection being connected on the sheet metal 35
Part 36 connects the fixed arm 1 and swing arm 2.This programme can satisfy and be arranged on sheet metal 35 by the sheet metal 35 of setting
The demand of different connectors 36, and installation connecting element 36 is more convenient.
Further, at least piece of metal piece 35 of sheet metal 35 for being connected to 3 both ends of ripple air buffer is set
It is equipped with connector 36, the ripple air buffer 3 connects the fixed arm 1 or swing arm 2 by the connector 36.For example,
The sheet metal 35 that glue can be used directly will be close to 1 one end of fixed arm is connected on fixed arm 1, and close to one end of swing arm 2
34 then are linked up with by welding on sheet metal 35, then ripple air buffer 3 is connected by swing arm 2 by hook 34.
Further, the ripple air buffer 3 uses rubber material.Rubber material after deformation recovery capability compared with
By force, the effect of buffering is more preferable, and longer life expectancy.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
