Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-Figure 4, the utility model provides a kind of machine making factory road lifting gear, comprises cabinet 1 and elevating lever, and elevating lever comprises the first bar 2 and the second bar 3.
One end of first bar 2 is rotatably connected on cabinet 1, is provided with passage 23 in the first bar 2, and the first bar 2 bottom surface is hinged with some 3rd bars 5, and many 3rd bars 5 are uniformly distributed along the axis direction of the first bar 2.The bottom surface of the first bar 2 is provided with the first hinged seat the 21, three bar 5 top and is arranged with two the 3rd crect ear 51, first hinged seats 21 between two the 3rd crect ears 51, and by the first rotating shaft 7 and two the 3rd crect ears 51 hinged.The both sides that the bottom surface of the first bar 2 is positioned at the first hinged seat 21 are provided with through hole 22, and the 3rd crect ear 51 is inner by the passage 23 inserting the first bar 2 after through hole 22.
Second bar 3 telescopically is installed in the passage 23 of the first bar 2, and the second bar 3 bottom surface is hinged with some 4th bars 4, and some 4th bars 4 are uniformly distributed along the axis direction of the second bar 3.The bottom surface of the second bar 3 is provided with groove 31 along its axis direction, groove 31 is evenly equipped with some paired and symmetrically arranged second hinged seats 32 in the axial direction, the top of the 4th bar 4 is provided with the 4th crect ear 41,4th crect ear 41 between paired two the second hinged seats 32, and is connected by the second rotating shaft 6.
Wherein, the width that the distance between the 3rd crect ear 51 of two, the 3rd bar 5 top is more than or equal to the second bar 3 bottom groove 31 is identical.
In addition, a side of the bottom of the 4th bar 4 is also provided with groove 42, groove 42 can be accommodated therein by the second hinged seat 32 and the 4th crect ear 41 being adjacent to another the 4th bar 4 place.
As shown in Figure 1 and Figure 5, when elevating lever is positioned at the state put down, second bar 3 is in elongation state, 3rd bar 5 and the 4th bar 4 are in the state perpendicular to the first bar 2 and the second bar 3 respectively, and when have vehicle etc. through out-of-date, second bar 3 is shunk in passage 23, now, 4th bar 4 swings to the right under the effect of the first bar 2 end, and the groove 31 being hidden in the second bar 3 is gradually inner, the bottom of the 4th bar 4 is provided with groove 42, groove 42 can by accommodated therein to the 4th crect ear 41 and the second hinged seat 32 that are adjacent to the 4th bar 4 top end, finally, all 4th bars 4 are made all to hold with the passage 23 of the first bar 2 inner with the second bar 3, and when the second bar 3 shrinks in passage 23, second bar 3 can withstand the 3rd crect ear 51 in insertion first bar 2 passage 23, 3rd bar 5 is also swung to the right, along with the continuation of the second bar 3 is shunk, second bar 3 is positioned at the bottom surface continuous action of groove 31 both sides at the 3rd crect ear 51, the 3rd bar 5 is made to be in the state swung all the time to the right, then the first bar 2 upwards rotates relative to cabinet 1, vehicle is passed through, when needs put down elevating lever, second bar 3 stretches out passage 23, under gravity, 3rd bar 5 and the 4th bar 4 slowly restPose.
