The door is fixed on the machine base through a hinge, and the door frames on the left side and the right side of the door are provided with air springs and hinged with the door. When upwards lifting the door, the manpower need overcome the moment of spring force and the gravity of door to the door, and when two pin joints of air spring and the pin joint of door on the frame were a straight line, the moment of spring to the door reduced to zero, continues to open, and then the moment direction of spring to the door changes, becomes the moment of overcoming the action of gravity, prevents that the door from falling under the action of gravity, keeps the door in the state of opening.
When the door is closed downwards, the spring force needs to be overcome firstly, after the door passes through the straight line position, the direction of the moment of the spring force on the door is changed, the direction of the moment of the spring force on the door is consistent with the direction of the moment of the gravity on the door, the door is kept in a closed state, and the door is not easy to open. On the occasion that needs the door to open downwards, if adopt the structure of lifting the door on, then need install the air spring additional in the both sides of door, if at this moment because the mechanical equipment spatial layout limits, can't or accurately install the air spring additional in the both sides of door. If the structure of lifting the door down is adopted, when the door is opened downwards, the gravity is the same as the opening direction of the door, if the excessive gravity is not offset, the door can fall down at an accelerated speed, the stop head at the lower part is impacted greatly, the door can be impacted reversely greatly, the service life of the door is influenced, and large noise is formed.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a downwardly opening door, comprising: the automatic door turning device comprises a machine base consisting of a vertical side plate and a transverse side plate, wherein a downward turning door is arranged on the outer side of the top of the vertical side plate in a downward turning manner through a hinge, a door connecting plate is fixedly arranged at the bottom of the inner side of the downward turning door, and a first connecting rod is hinged to the door connecting plate;
the lower portion of the inner side of the vertical side plate is provided with a gas spring seat, the gas spring seat is hinged with a gas spring, the lower side of the transverse side plate is hinged with a bending connecting rod which bends downwards, the bending connecting rod is hinged to the transverse side plate by taking the bending position of the bending connecting rod as a rotating shaft, one end of the bending connecting rod is hinged to the first connecting rod, and the other end of the bending connecting rod is hinged to the gas spring.
Based on the above, the vertical side plate and the horizontal side plate are vertically arranged.
Based on the above, the outside of the downward-turning door is provided with the handle.
Based on the above, the length value of one side of the bending connecting rod hinged with the first connecting rod is larger than that of one side of the bending connecting rod hinged with the gas spring.
On the basis, the hinge is arranged on the outer side of the top of the vertical side plate, and the downward-turning door can be turned over and vertically spliced on the top of the vertical side plate.
Specifically, in the downward-opening door, the lower part of the downward-opening door is fixed on a vertical side plate of the machine base through a hinge, and the downward opening or upward closing can be realized by pulling a handle. The downward turning door, the first connecting rod and the bending connecting rod form a reverse four-bar mechanism together.
When the downward-turning door is opened downwards, the air spring is compressed, the reaction force acts on the reversing four-bar mechanism, a moment opposite to the opening direction is given to the downward-turning door, the moment of gravity on the downward-turning door is consistent with the opening direction of the downward-turning door, when the door is heavy, the gravity applied to the downward-turning door is directly related to the opening comfort and safety, the reverse moment of the air spring plays a role in counteracting the influence of the gravity applied to the downward-turning door, and the downward-turning door cannot fall down heavily. And the labor is saved when the vertical turnover door is closed upwards, so that the safety is ensured, and the operation comfort is also improved.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a door of opening downwards, mechanism simple structure, the processing requires lowly, and is with low costs, easily realizes, has effectively avoided simultaneously turning down the impact and the noise that the door falls the production with higher speed, has prolonged life. Not only ensures the safety, but also increases the comfort of the operation. Meanwhile, the mechanism is arranged in the space below the downward-turning door, so that the space in the front-back direction and the side surface of the downward-turning door cannot be influenced, and enough space is reserved for arrangement and disassembly of machine parts inside the downward-turning door.
