Description

Translation type closed door buffer structure

This work is about a closed-door buffer structure, especially a translational closed-door buffer structure.

Press, a buffer generally used for closed door buffering, as shown in Patent No. M474064 of the Republic of China, which is installed between the door and the door panel, and drives the rotary shaft to actuate when the door is opened, so that the rotary shaft and the rotary gear rotate synchronously, At the same time, the mandrel of the pneumatic cylinder is pulled outward, and when the door is closed, the rotating shaft and the rotating gear rotate in the opposite direction, and at the same time, the movable casing pushes the pneumatic cylinder inward to produce the effect of automatic pulling and buffering.

However, although the shock absorber generally used for door closing buffer can achieve the effect of door closing buffer, when the user wants to open the door, a large force is required to make the above-mentioned rotating shaft actuate the air cylinder mandrel outward. Pull, when the user is relatively weak, it is easy to cause the inconvenience that the door cannot be opened smoothly.

Therefore, how to eliminate the above-mentioned deficiencies is the technical difficulty that the creator of this case intends to solve.

In view of the above problems of the existing door closing buffer, the purpose of the present invention is to provide a translational door closing buffer structure.

In order to achieve the above purpose, the creation system provides a closed-door buffer structure, which includes:

A buffer, the buffer is provided with a buffer fixing seat, the buffer fixing seat is fixed on the door, and the buffer is provided with a first torsion spring accommodating groove, a release column track, and a buffer rod fixing piece , a fixing hole is arranged on one side of the first torsion spring accommodating groove, and a shaft hole is arranged in the first torsion spring accommodating groove, and a stop part is arranged on one side of the release column track;

a torsion spring, the torsion spring is fixed in the first torsion spring accommodating groove of the buffer, the torsion spring is provided with a first end and a second end, and the first end is fixed in the fixing hole of the buffer middle;

A sliding block, the sliding block is provided with a second torsion spring accommodating groove, a release column shaft hole, a first oblique opening, and a shaft hole, the second torsion spring accommodating groove is for the second end of the torsion spring to be installed ;

a release column, one side of the release column is provided with a release column shaft, the release column shaft is set in the release column shaft hole of the sliding block, and the release column is set in the first inclined opening;

A lever, the lever is provided with a shaft, a bearing, a second oblique opening, and a buffer rod fixing shaft, the shaft is inserted through the shaft hole of the sliding block and accommodated by the first torsion spring of the buffer the shaft hole of the slot, and the second oblique opening is provided for the release post;

More preferably, the release column moves along the release column track.

a buffer rod, one end of the buffer rod is fixed on the buffer rod fixing member of the buffer, and the other end of the buffer rod is fixed on the buffer rod fixing shaft of the lever;

A door frame side fixing seat, the door frame side fixing seat is fixed on the door frame, and the door frame side fixing seat is provided with a track, the track is used for the bearing of the lever to slide into.

When the door is opened, the bearing on the lever moves outward along the track of the fixing seat on the side of the door frame. When the lever moves outward, the second oblique opening pushes the release post and pushes against the sliding block The first oblique opening of the sliding block drives the sliding block to rotate, and the release column moves along the track of the release column. As the sliding block rotates and the second torsion spring accommodating groove of the sliding block drives the second end of the torsion spring to make the torsion spring The torsion force of the spring increases, and the buffer rod is also pulled out with the movement of the lever; and when the lever continues to move outward, the second oblique opening continues to push the release post, and the release post continues to abut the release post. The first oblique opening of the sliding block drives the sliding block to rotate, the release column continues to move along the track of the release column and enters the blocking portion, and the bearing of the lever is released from the track of the fixing seat on the side of the door frame.

When the door is closed, the bearing on the lever enters the track of the fixing seat on the side of the door frame. When the lever moves inward, the second oblique opening of the lever pushes the release post so that the release post escapes the stop and enters the door. In the release column track, the release column pushes against the first oblique opening of the sliding block to drive the sliding block to rotate, and the buffer rod is retracted inward with the movement of the lever for buffering; and when the lever continues to move inward , the second oblique opening pushes the release column to move continuously along the track of the release column, the release column pushes against the first oblique opening of the sliding block and drives the sliding block to rotate; finally, when the door is about to be closed, the torsion spring releases The torsional force drives the sliding block and the release column to close the door.

With the above structure and action description, the present invention can achieve the effect of easily opening the door in addition to the door-closing buffer, which improves the traditional door-closing buffer that requires a relatively large effort to open the door when trying to open the door.

In addition, the present invention is further provided with one or more stabilizing blocks, each of which is arranged on the shaft of the lever, each of the stabilizing blocks is provided with a track and a stop portion, and the track of each of the stabilizing blocks and the The stop part is opposite to the release column track of the buffer and the stop part, and the release column moves along the track of the stabilizer block and the release column track of the buffer which is opposite to each other, so that the present invention can be realized. The stability of the movement of the release column is further improved.
