- Figure 10 referring to fig. 2, the fixing seat and mounting base are made of plastic material, and the fixing seat and mounting base are equal
For engraved structure.It is intended that when fixing seat and mounting base lead to the first extension for some reason in the fabrication process
When the lateral dimension or/and longitudinal size of 4-2 and the second extension 2-2 are slightly larger than the size of the inner cavity of metal tube 1, due to solid
Reservation and mounting base are made of plastic material, and are engraved structure, thus have elasticity well, so as to be got into
In the inner cavity of metal tube 1, to realize assembly.
- Figure 10 referring to fig. 2, the sliding slot 4-5 are made of rectilinear extension 4-7 and bending section 4-6, wherein the straight line
One end in guide pin 4-3 far from fixing seat is arranged in extension 4-7, and along the direction linear extension close to fixing seat；Institute
It states bending section one end 4-6 to connect with one end in rectilinear extension 4-7 far from fixing seat, the other end is bent downwardly.
The telescopic rod of-Figure 10 referring to fig. 2, the sliding part 3 and damper 2-3 are rotatablely connected, and are leaned on the sliding part 3
The hook of the telescopic rod of nearly damper 2-3 is the first hook 3-1, is the second hook 3-2 far from telescopic rod；Wherein, described
The width of two hook 3-2 is not more than the width of the escape groove 1-1；The width of the first hook 3-1 is greater than escape groove 1-1's
Lower end of width, the first hook two sides 3-1 is provided with confined planes 3-6, and the confined planes 3-6 is towards the direction far from telescopic rod
Inclination upwards；The sliding block 3-4 is mounted on the region being located at below the second hook 3-2 in sliding part 3.
Referring to Fig. 1-Figure 11, the working principle of the damping buffer unit of the utility model is:
The damping buffer unit of the utility model is fixed on guide rail.
When pushing, the sliding part 3 is moved together with sliding door, when the sliding block 3-4 in sliding part 3 is in sliding slot 4-5
Rectilinear extension 4-7 sliding when, due to the actuator on sliding door be located at two in sliding part 3 link up between driver slot
In 3-5, therefore, sliding door will not only overcome the elastic force of spring 2-4 during opening, but also overcome damper 2-3
To its resistance, ensure that sliding door will not be because of applying excessive active force during opening to it when pushing in this way
And it impinges upon on doorframe.When the sliding block 3-4 on the sliding part 3 enters bending section 4-6 from rectilinear extension 4-7, due to
The width of the second hook 3-2 is not more than the width of escape groove 1-1, and rotates between the sliding part 3 and the telescopic rod
Connection, therefore, the rotation counterclockwise of sliding part 3, so that the second hook 3-2 is downwardly turned over and entered escape groove 1-1
It is interior.Due to linking up with the blocking of 3-2 without second, the actuator on the sliding door can be detached from the driving on sliding part 3
Slot 3-5, at this moment, sliding door can move forward and not will receive any resistance.In the process, due to described first
The width for linking up with 3-1 is greater than the width of escape groove 1-1, and the lower end of first hook 3-1 is provided with towards the side far from telescopic rod
To acclivitous confined planes 3-6, therefore, the angle that the sliding part 3 rotates counterclockwise and the gradient of confined planes 3-6 have
It closes.When the surface flat contact of the confined planes 3-6 of the first hook 3-1 and the metal tube 1, the sliding part 3 stops
Spin-ended turn.Since inertia force of the sliding door in opening procedure passes through the weakening of spring 2-4 and damper 2-3, so that the push-and-pull
Inertia force of the door after the damping buffer unit for being detached from the utility model has substantially reduced, therefore will not occur with doorframe violent
It hits, will not only damage doorframe in this way, nor huge noise can be generated.
At closing time, the sliding door is moved on guide rail so that the actuator of the sliding door moves to the drive on sliding part 3
In dynamic slot 3-5 and the first hook 3-1 is squeezed, this will apply an active force to sliding part 3, so that sliding part 3 is towards close to resistance
The direction of Buddhist nun's device 2-3 moves, when the sliding block 3-4 on sliding part 3 enters rectilinear extension 4-7 by the bending section 4-6 of sliding slot 4-5
When, the sliding part 3 rotates clockwise, so that the second hook 3-2 is flipped up, thus again by the driving on sliding door
Part is clamped in the driver slot 3-5, and the sliding part 3 is moved towards the direction close to damper 2-3 together with sliding door.
In the process, the sliding part 3 by sliding door to its driving force and spring 2-4 to its elastic force, the driving force
It is identical as the direction of motion of sliding part 3 with the direction of elastic force.In addition, the sliding part 3 also by the damper 2-3 to its
Resistance, which can increase with the increase of the driving force and elastic force, so that the speed of sliding door is gradually reduced.Thus
Buffer function is played to sliding door, sliding door is slowly closed.
Since the metal tube 1 of the damping buffer unit of the utility model is straight tube, and section in the longitudinal direction is equal
Identical, therefore, the metal tube 1 can be directly made by the technique of extrusion forming, and can according to need under cutting
To correspond to the metal tube 1 of length.Therefore, compare sheet metal part in the prior art must by way of punching press system
, the manufacturing process of the metal tube 1 of the utility model is simpler, and manufacturing cost is lower.In addition, work people in assembly
Guide part 4 need to be only inserted by member from the side of metal tube 1, and buffer gear 2 is inserted into from the other side of metal tube 1, and leads to
Locking mechanism is crossed to be locked on metal tube 1.In the process, the sliding block 3-4 on the sliding part 3 in buffer gear 2 will be with
Sliding slot 4-5 cooperation in guide part 4, to complete the installation of damping buffer unit.In terms of existing technologies, this is practical new
The assembly method of the damping buffer unit of type is simpler, and assembly cost is lower.
Above-mentioned is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above content
It limits, it is made under other any spiritual essence and principles without departing from the utility model to change, modification, substitution, combine, letter
Change, should be equivalent substitute mode, be included within the protection scope of the utility model.
