DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Reference Figure 1-Figure 4 An adjustable oil cylinder support comprises a base 1, an oil cylinder sleeve and a driving assembly. The upper surfaces of the base 1 are fixedly connected with pillars 2 at both ends thereof. An installation groove is provided inside the base 1 and in the direction of the connection line between the two pillars 2. Two support plates 12 are fixedly connected in the installation groove. A lifting column 3 is axially slidably connected inside the pillar 2. A supporting mechanism is fixedly connected to the top surface of the lifting column 3.

[0023] The oil cylinder sleeve comprises an outer sleeve 5 and an inner sleeve 7. A spring 6 is fixedly connected to the inner surface of the inner sleeve 7. There are four springs 6 and they are arranged equidistantly on the circumference of the inner sleeve 7. The outer sleeve 5 and the inner sleeve 7 rotate with each other and a ball bearing is connected between the relative surfaces. Both ends of the oil cylinder sleeve are movably connected to the supporting mechanism. The supporting mechanism comprises a support 4 fixedly connected to the top of the lifting column 3. One end of the support 4 is fixedly connected to the second rotating shaft 17. The second rotating shaft 17 is rotatably connected to the oil cylinder sleeve. A through hole 19 is communicated between the support 4 and the second rotating shaft 17. The through hole 19 is threadedly connected to a screw 18.

[0024] The driving assembly includes a first rotating shaft 11 rotatably connected at the center of the support plate 12, two second bevel gears 10 are fixedly connected to the first rotating shaft 11, and the two second bevel gears 10 are respectively fixedly connected to one end surface of the first rotating shaft 11 and an axis at a certain distance from the other end surface. The second bevel gear 10 is meshed with a first bevel gear 9 on the upper side, and a lead screw 8 is fixedly connected to the upper surface of the first bevel gear 9. The lead screw 8 passes through the upper surface of the base 1 and is threadedly connected to the lifting column 3 inside the pillar 2. The driving assembly also includes a turntable 13 fixedly connected to an end surface of the first rotating shaft 11 without the second bevel gear 10, and a rotating rod 14 is fixedly connected to the side of the turntable 13 facing away from the base 1. The lead screw 8 can be rotated by hand-cranking the rotating rod 14, thereby causing the lifting column 3 to move linearly to change the height of the cylinder sleeve. A limiting rod 15 is threadedly connected to the turntable 13, and a plurality of limiting holes 16 that can be threadedly connected to the limiting rod 15 are provided on the side of the base 1 facing the turntable 13, and the limiting holes 16 are arranged in a circular shape with equal distances around the first rotating shaft 11.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] When in use, the oil cylinder is installed in the inner sleeve 7, and the spring 6 in the inner sleeve 7 ring holds the oil cylinder tightly. A ball bearing is connected between the relative surfaces of the outer sleeve 5 and the inner sleeve 7, so that the oil cylinder can rotate in the oil cylinder sleeve. The rotating rod 14 is shaken to rotate the rotating disk 13, drive the first rotating shaft 11 to rotate, and rotate the second bevel gear 10. The first bevel gear 9 and the second bevel gear 10 are meshed and rotated with each other, so that the lead screw 8 rotates. The lead screw 8 is connected with the lifting column 3 by threads, so that the lifting column 3 can move up and down to adjust the height of the oil cylinder sleeve. After the adjustment is completed, the rotating disk 13 and the limiting hole 16 are threadedly connected with the limiting rod 15, so that the height of the oil cylinder sleeve can be fixed. When the angle of the oil cylinder needs to be adjusted, the screw 18 is loosened, the angle of the oil cylinder is adjusted as needed, and the screw 18 is tightened. The screw 18 presses the oil cylinder sleeve, and the oil cylinder sleeve can no longer rotate, and the angle is fixed. The utility model is flexible and convenient to use and is suitable for use under various working conditions.
