Abstract
Description
The present invention relates to a slide rail deceleration damper damping system for a door, and is provided by sequentially connecting a reduction gear train and a damper damper to a sliding actuating elastic actuator to reduce the moving distance of the elastic actuator and to transmit the damping damper to the damping damper. The present invention relates to a slide rail deceleration damper damping system that not only enables miniaturization, but also increases durability by reducing impact due to movement of the elastic actuator.
In general, the buffer damper is installed between the two objects that cause each other to impact each other, such as doors provided in furniture or home appliances, to mitigate each other's impact when they collide with each other, such as a closet or kimchi refrigerator, etc. It is mainly used for the purpose of being installed between the slack and the slack so that it can be closed slowly by preventing the smash from colliding with the slack suddenly.
Here, the conventional damper damper is coupled to the cylinder filled with the fluid and one end is exposed to the outside and the other end is disposed in the cylinder and the end of the rod disposed inside the cylinder and the flow of fluid when the rod emerges It is configured to include a fluid resistor is formed in the fluid passage of a fine size to allow the rod to emerge slowly to control.
In addition, the inner circumferential surface of the cylinder is in close contact with the outer circumferential surface of the rod to receive the fluid resistance inside the cylinder when the fluid is moved, so that the fluid passes only through the minute fluid passage, and as a result, a small diameter portion is formed to gradually move the fluid resistor. .
However, the conventional buffer damper as described above has the following problems.
First, in the case of furniture or a large refrigerator, the buffer damper also had to be enlarged because the moving distance of the damper shaft was increased. Second, it was vulnerable to bending or deformation due to the extension of the shaft length due to the enlargement of the damper. , Third, when the rod is suddenly moved to the rear end of the cylinder by an external impact, the impact is applied to the rear end of the cylinder as it is, the rear end of the cylinder burst, there was a problem that the cylinder is broken.
The present invention has been made in order to solve the above problems, first, the amount of movement of the elastic actuator is reduced through the reduction gear train to be transmitted to the damper damper, so that the shaft of the damper damper can move a relatively small distance The shock absorber can be miniaturized. Second, the shaft can be prevented from being warped or deformed due to the shortening of the shaft. Third, the shock absorber is provided with first and second shock absorbers, respectively. The present invention provides a slide rail deceleration damper damping system that prevents damage to the cylinder housing due to a moving shock of the shaft, thereby enabling the durability to be remarkably improved.

The reduction gear train may include a drive reduction gear coupled to the drive rack, a driven reduction gear coupled to the buffer damper, and an idle reduction gear provided between the drive reduction gear and the driven reduction gear. have.
On the other hand, the buffer damper is filled with a fluid inside the hollow cylinder housing is slidably installed in the main housing, one end is disposed in the cylinder housing and the other end is exposed to the outside fixed to the main housing and the fluid Consists of a shaft which is installed while receiving the resistance of, the outer circumferential surface of the cylinder housing is provided with a driven rack of a predetermined length to be engaged with the reduction gear train.
Here, the shaft has a fluid resistor for controlling the flow of the fluid when it emerges from the cylinder housing to generate a resistance of the fluid, the cylinder housing forms a small diameter portion so that the inner peripheral surface is in close contact with the outer peripheral surface of the fluid resistor, The rear end portion may be provided with a first buffer portion and a second buffer portion each having a large diameter portion so as to be spaced apart from the outer peripheral surface of the fluid resistor to reduce the fluid resistance.
In addition, the first buffer portion is preferably composed of a large diameter portion of a predetermined length and a fluid guide surface respectively formed to be inclined at both ends of the large diameter portion.
In addition, the fluid resistor is extrapolated to the end of the shaft, the fluid guide member is provided so that the outer peripheral surface is in close contact with the inner peripheral surface of the small diameter portion of the cylinder housing, a plurality of fluid flow holes through which the fluid can pass through; It may be composed of a joint coupled to the upper end of the fluid guide member.
