Detailed Description
The present invention will be further described with reference to the accompanying drawings. An improved structure of a drawer guide rail buffer comprises a base 2, a sliding block 4, an oil cylinder 5 and a spring 6, wherein the base 2 is used for being connected with a fixed rail 1, the sliding block 4 is used for being connected with a movable rail 3 and can pull the movable rail 3 to automatically buffer and reset, and the oil cylinder 5 and the spring 6 are used for connecting the base 2 and the sliding block 4; the method is characterized in that:
a first guide rail 21 and a second guide rail 22 are arranged on the base 2 in parallel, a hanging and buckling rail 23 extends in an arc shape from the front end of the first guide rail 21 to the direction of the second guide rail 22, and the hanging and buckling rail 23 extends downwards to intersect with the second guide rail 22;
the back surface of the sliding block 4 is provided with a guide groove 41, the guide groove 41 covers the first guide rail 21 and the second guide rail 22, the sliding block 4 slides along the first guide rail 21, the second guide rail 22 and the hanging and buckling rail 23 under the guiding action of the guide groove 41, the sliding block 4 is provided with an oil cylinder hole 42, one end of the oil cylinder 5 is fixed on the base 2, and the other end of the oil cylinder 5 is hinged with the oil cylinder hole 42; the bottom of the sliding block 4 extends downwards to be provided with a tension spring block 43 in a protruding mode, a tension spring groove 44 is formed in the tension spring block 43, one end of the spring 6 is fixed on the base 2, the other end of the spring is hung and buckled on the tension spring groove 44, and the sliding block 4 is pulled to move towards the closing direction; the front surface of the sliding block 4 is also provided with a hanging buckle groove 45, and the hanging buckle groove 45 is hung and buckled or separated with the hanging plate 31 arranged on the movable rail 3;
the second guide rail 22 is provided with a clearance groove 24, the clearance groove 24 is arranged in a shape like a Chinese character 'ba', and when the sliding block 4 swings into the hanging buckle rail 23, the tension spring block 43 of the sliding block 4 swings into the clearance groove 24.
The tail end of the hanging and buckling rail 23 transversely extends to be provided with a third guide rail 25, and the third guide rail 25 is arranged in parallel with the first or second guide rail 22.
The upper side edge of the guide groove 41 is provided with an inner groove 46 in an upward concave manner, so that the right side of the groove protrudes to form a hanging and buckling block 47, an arc hanging and buckling surface 48 is arranged between the hanging and buckling block 47 and the right side wall of the inner groove 46, and the arc hanging and buckling surface 48 is positioned on the first guide rail 21 and the hanging and buckling rail 23 to slide.
The working principle is as follows: as shown in fig. 1, 2 and 3, when the guide rail is in a closed state, the hanging plate 31 of the movable rail 3 is hung and buckled in the hanging and buckling groove 45 on the sliding block 4, and the sliding block is always kept in a closed state under the action of the spring 6, so that the closed state of the drawer is kept.
As shown in fig. 4 and 5, when the guide rail is opened, the movable rail utilizes the hanging plate 31 to pull the sliding block to be opened outwards, the sliding block slides along the first guide rail and the second guide rail, and correspondingly pulls the spring and the oil cylinder to move outwards to be opened. When the sliding block runs to the tail end of the first guide rail, the sliding block moves towards the direction of the hanging and buckling rail 23 along the first guide rail, so that the front end of the sliding block deflects, the arc hanging and buckling surface 48 on the sliding block is hung and buckled on the hanging and buckling rail 23, and the tension spring block 43 of the sliding block 4 partially swings into the clearance groove 24. The clearance groove plays a role in clearance, and therefore a swing space is provided for the deflection of the sliding block. After the sliding block deflects, the sliding block is separated from the hanging plate 31, and the guide rail is continuously opened outwards. And under the pulling action of the spring below the sliding block, the sliding block is forced to always keep a deflection state and is hung and buckled on the hanging and buckling rail 23 for fixing.
When the guide rail needs to be closed again, link plate and slider striking on the activity rail force the slider to produce and deflect for in slider and link plate are hung and are detained and get back to first guide rail and second guide rail again, the slider under the effect of spring and hydro-cylinder, pulling slider and guide rail slowly close, thereby played the buffering reset action when the drawer guide rail closes.
Compared with the prior art, parallel arrangement has first guide rail and second guide rail on the base in the present case, and two guide rails play the guide effect to the slider jointly for the slider moves more steadily. Meanwhile, the slide block in the scheme can be directly deflected and hung and buckled with the hanging and buckling rail by virtue of the arrangement of the clearance groove on the second guide rail, so that the spring and the buffer can be directly connected with the slide block without an intermediate connecting piece, the functions of the spring and the buffer are realized, the internal structure of the spring and the buffer is simplified, the installation process is simplified, the production cost is reduced, and the slide block can be widely popularized and used.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
