Specific embodiment
Below with reference to each attached drawing, the utility model is described in detail.
The bidirectional damper buffer hinge includes shell 1, block 2 of locking a door, elastic mechanism 3 and two-way slow combined with Figure 1 and Figure 2,
Punch mechanism 4, it is preferred that door body limit fastener 8 is also equipped on block 2 locking a door, the door body that need to be installed can be along 2 length side of block of locking a door
To installation and door body limit fastener 8 is withstood in one end, realizes the limit of door body installation.The block 2 of locking a door is rotated by rotation axis 11
It is installed on shell 1, the elastic mechanism 3 includes tension spring 31 and support frame 32,32 one end of support frame as described above rotation connection lock
Door block 2, the other end connect two-way buffering mechanism 4, and the other end of the two-way buffering mechanism 4 is connected with tension spring 31, the tension spring
31 other ends are fixed in shell 1.When block 2 of locking a door is rotated counterclockwise along rotation axis 11, tension spring 31 is pulled to stretch, it is described double
It can produce the power opposite with 31 draw direction of tension spring to buffer gear 4, so that the block 2 that makes to lock a door is rotated counterclockwise and slowed；When
When block 2 of locking a door is rotated clockwise along rotation axis 11, tension spring 31 is pushed to retract, the two-way buffering mechanism 4 can produce and tension spring
The opposite power of 31 retracted orientations, so that the block 2 that makes to lock a door is rotated clockwise and slowed.
Hereinafter, illustrating the structure of the two-way buffering mechanism 4.In conjunction with Fig. 3 and Fig. 4, the two-way buffering mechanism 4 is wrapped
Sliding rack 41, damper 42 and pull rod 43 are included, the sliding rack 41 has inner hollow and both ends protrusion, and for pull rod 43
Freely through sliding groove 411, the pull rod 43 offer rectangular aperture 431.The diameter of the damper 42 is slightly less than rectangle
The width of opening 431, and damper 42 is placed in sliding groove 411, due to the bore size of the right and left of sliding groove 411
Less than the diameter of damper 42, therefore, damper 42 does not fall out sliding groove 411.Sliding rack 41 is fixed on inside shell 1,
When pulling pull rod 43 to move downward, the right of rectangular aperture 431 is withstood damper 42 and is moved downward, when the left side of damper 42
When withstanding the left side of sliding groove 411, damper 42 generates damping buffering power, to slow down the speed that pull rod 43 moves downward；When
When pull rod 43 being pulled to move right, the left side of rectangular aperture 431 is withstood damper 42 and is moved right, when the right side of damper 42 is pushed up
Firmly when the right side of sliding groove 411, damper 42 generates damping buffering power, to slow down the speed that pull rod 43 moves right.Also,
The left side of pull rod 43 is connected on support frame 32, the right side of pull rod 43 is connected to tension spring 31, so that elastic mechanism 3 is controlling
While block 2 of locking a door opens and closes, it is provided with bidirectional damper buffer capacity.Above-mentioned two-way buffering mechanism 4 is, it can be achieved that two opposite directions
Buffering, thus for hinge opening and closing be provided which buffer function, have reached the above-mentioned technical effect of the utility model.
In conjunction with Fig. 5-Fig. 7, the block 2 of locking a door is a strip hard laminate, is opened up on the ontology for locking a door 2 lower part of block
There is the first sliding groove 21 with certain radian.It is coaxially fixed with limit shaft 61 on the wheel 5 of locking a door, the wheel 5 that will lock a door rotates
It is installed on support frame 32, and the cooperation of wheel 5 of locking a door simultaneously is caught in first sliding groove 21.Therefore, when block 2 of locking a door is outer along being fixed on
When rotation axis 11 on shell 1 rotates clockwise, wheel 5 of locking a door is moved upwards along first sliding groove 21, and pushes support frame 32 to the right
Movement；When block 2 of locking a door is rotated counterclockwise along the rotation axis 11 being fixed on shell 1, wheel 5 of locking a door is downward along first sliding groove 21
Movement has certain length, guarantee is locked a door, and wheel 5 is lateral to be transported due to the arc moulding of first sliding groove 21 in the horizontal direction
Momentum, so that support frame 32 be pulled to move downward.
As shown in figure 8, locking a door, the rotation of block 2 drives support frame 32 since support frame 32 has gap between 1 inner wall of shell
In moving process, support frame 32 can collide 1 inner wall of shell due to shaking, cause noise.Therefore, fixed on 1 inner wall of shell
The locating button 7 of one " door " font, support frame 32 is buckled in locating button 7, so that the collision between support frame 32 and shell 1 is eliminated,
Preferably, using the locating button of plastic cement material 7, lateral buffering is further provided for during support frame 32 shakes, to more have
32 noise of reduction support frame of effect.The locating part 62 of plastic cement material is further fixed on inside shell 1, the locating part 62, which passes through, to be turned
Moving axis 11, but do not rotated with rotation axis 11, and there is the second sliding slot 621 for laterally opening up certain length on locating part 62, and
In the two sides for locking a door block 2, it is mounted on locating part 62.It is limited above-mentioned with the co-axially fixed limit shaft 61 of wheel 5 insertion of locking a door
In the second sliding slot 621 of part 62, when the movement of wheel 5 is locked a door in the drive of block 2 of locking a door, since limit shaft 61 receives second sliding slot 621
Cross spacing effect, the wheel 5 that guarantees to lock a door is mobile by the direction of second sliding slot 621, to guarantee support frame 32 and tension spring 31
Transverse shifting is kept, prevents longitudinal offset from causing collision and extruding between about 1 inner wall of shell, influences hinge opening and closing
Smooth degree.Meanwhile the regular length of second sliding slot 621, the rotational angle for block 2 of locking a door can also be limited, for limiting door body
Folding angle.
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
His relevant technical field similarly includes within the protection scope of the present utility model.
