Description
Technical Field
The invention relates to the field of home decoration, in particular to a door spindle.
Background
At present, doors used in daily life of people are generally divided into a sliding door and a horizontal opening door, and the installation mode of a vertical opening door can be divided into door shaft connection and hinge connection; therefore, people have installed supporting door-inhale and door-inhale post behind the door and on the wall, the door-inhale can adsorb on the door-inhale post before colliding the wall, make and produce a space between door and the wall, people still need the attention control speed of opening the door in the back half-range of opening the door, the door-inhale of careful wing adsorbs on the door-inhale post, avoid sending very big sound, and the difficult assurance of adsorption affinity between door-inhale and post, if too big then need the great strength of speaking cost to pull open the door, if adsorption affinity is less, hardly play the effect of fixing the door.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide an annular self-locking buffer door spindle, which can make the door spindle more uniformly stressed, prolong the service life of the door, and effectively fix the door to avoid the collision between the door and the wall.
The technical scheme adopted by the invention for realizing the technical purpose is as follows: the annular self-locking buffer door shaft comprises a door shaft; a circular track cavity is arranged outside the door shaft, the circular track cavity is horizontally fixed on the ground, and the circular track cavity and the door shaft are coaxially arranged; an arc guide rail bar is arranged in the circular track cavity and is in sliding contact with the inner wall of the circular track cavity; a strip-shaped opening is formed in the inner side wall of the circular track cavity along the circumferential direction, and the arc length range of the strip-shaped opening is set to be the arc length corresponding to the central angle of 90-105 degrees; the door shaft is fixedly connected with a connecting rod, the other end of the connecting rod penetrates through the strip-shaped opening to be connected to the middle position of the arc-shaped guide rail bar, and the door shaft drives the arc-shaped guide rail bar to slide in a circular track cavity limited by the strip-shaped opening through the connecting rod; an exhaust section is arranged on the circular track cavity, the starting point of the exhaust section is arranged at the edge of the strip-shaped opening, and the arc length range of the exhaust section is set to be the arc length corresponding to the central angle of 90-105 degrees; a blocking piece is arranged at the tail part in the exhaust section and is used for completely blocking the inside of the circular track cavity; when the connecting rod is clamped at the edge of the strip-shaped opening, the end part of the arc-shaped guide rail bar is in elastic contact with the blocking piece; the baffle is provided with an exhaust hole; and through holes are uniformly distributed in the exhaust section along the circumferential direction of the circular track cavity.
Preferably, a door is mounted on the door shaft; an air valve is arranged at the exhaust hole, the air valve is connected to the door handle in a transmission way, the air valve is opened by rotating the door handle, and air pushed by the arc-shaped guide rail strip can be exhausted from the valve; when the door handle returns to the original position, the air valve is closed, when the arc guide rail bar slides to be in elastic contact with the blocking piece, the arc guide rail bar and the blocking piece are in a vacuum state to a certain degree, the arc guide rail bar is pressed on the blocking piece by air pressure, the arc guide rail bar cannot be separated from the blocking piece unless high strength is used, and the door is firmly fixed.
Preferably, the arc length of the strip-shaped opening is set to be the arc length corresponding to the central angle of 180 degrees, and the exhaust section is arranged in the other half of the circular track cavity corresponding to the strip-shaped opening; the baffle plate is arranged in the middle of the exhaust section; the air vent on the blocking piece is cancelled, the angle range of the rotation of the connecting rod is increased to 180 degrees, the sliding angle range of the arc guide rail bar is also increased to 180 degrees, when the door is in a closed state, the connecting rod is positioned in the middle of the strip-shaped opening, the door is rotated clockwise or anticlockwise, and the door can be opened inwards or outwards.
Preferably, the lubricant is arranged at the bottom in the circular track cavity, so that the problem that the door is difficult to rotate due to overlarge dynamic friction force when the arc guide rail bar slides in the circular track cavity is prevented; rubber pads are arranged at two ends of the arc-shaped guide rail bar, so that the arc-shaped guide rail bar is prevented from generating a loud sound when being impacted on a baffle.
The invention has the beneficial effects that: the annular self-locking buffer door spindle is arranged on the ground, the door is arranged on the door spindle, the door rotates around the door spindle in the process of opening the door, the weight of the door is dispersed on the door spindle, the connecting rod and the arc guide rail bar, the stress of the door spindle is reduced, and the possibility that the door inclines to one side after long-time use is reduced; when the door is in a closed state, the connecting rod is positioned at the edge of one side of the strip-shaped opening, the door is opened, the arc-shaped guide rail strip slides in the circular track cavity to discharge air in the circular track cavity from the through hole, the arc-shaped guide rail strip is slowed down by air resistance motion in the process of extruding the air to play a role of buffering, the through holes are blocked one by one along with the sliding of the arc-shaped guide rail strip, the through holes capable of exhausting are reduced one by one, the resistance suffered by the arc-shaped guide rail strip is also gradually increased, the buffering effect is more obvious, when the connecting rod is clamped at the edge of the other side of the strip-shaped opening, the arc-shaped guide rail strip slides to be in elastic contact with the blocking piece to block the exhaust hole, the air-tight state of a certain degree is kept between the arc-shaped guide rail strip and the blocking piece, the door is locked at a completely opened position, certain strength is required when the door is, the door is prevented from colliding with the wall, and the door can be fixed when the door is completely opened, so that the door is prevented from being blown by wind.
