[0024] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example

[0025] like Figure 1-4As shown, the utility model provides a hydraulic cylinder that is easy to move, including a cylinder housing 1, a support ring sleeve 2 is symmetrically fixed on the outer surface of the cylinder housing 1, and a rolling groove 4 with an open side is opened inside the two support ring sleeves 2, and a moving ball 5 is slidably sleeved inside the rolling groove 4, and a connecting screw 6 is fixed on the side of the two moving balls 5, and the two connecting screws 6 are both arranged in a horizontally placed "T" shape, and a thread is provided on the connecting screw 6 to cooperate with a fixing nut 7, and the diameter of each fixing nut 7 is larger than the diameter of the connecting screw 6. The two support ring sleeves 2 are provided with a rolling groove 4 with an open side, and the rolling groove 4 is provided with a moving ball 5. The outer surface is glued and fixed with a shock-absorbing rubber sleeve 3, and a connecting cross plate 8 is fixed between the two connecting screws 6 that pass through one end of the outer side of the support ring sleeve 2. A threaded sleeve is provided on the connecting screw 6 on the side of each support ring sleeve 2 with a fixing nut 7 for clamping the shock-absorbing rubber sleeve 3, and the height of the fixing nut 7 is greater than the height of the rolling groove 4, which makes it convenient to twist the fixing nut 7 to clamp the shock-absorbing rubber sleeve 3. The vertical sections of the two rolling grooves 4 are both "convex" types that match the moving ball 5 and the connecting screw 6, ensuring that the moving ball 5 can slide inside the rolling groove 4 but will not separate from the rolling groove 4;

[0026] When the cylinder housing 1 needs to be moved, the fixing nuts 7 on both sides are screwed to move the fixing nuts 7 away from the support ring sleeve 2, so that the fixation between the moving ball 5 and the support ring sleeve 2 can be released. At this time, the moving ball 5 can slide inside the rolling groove 4, pulling the connecting cross plate 8 to drive the cylinder housing 1 to roll and move. When the cylinder housing 1 rolls and moves, the moving ball 5 slides inside the rolling groove 4, making it more labor-saving when the cylinder housing 1 moves.

[0027] The top of the connecting horizontal plate 8 is connected to a pulling sleeve 12 for pulling through an adjusting assembly. An adjusting screw 14 is threadedly sleeved inside the pulling sleeve 12. Limit rods 15 are fixed at both ends of the adjusting screw 14. A threaded hole that cooperates with the adjusting screw 14 is opened at the end of the pulling sleeve 12 away from the hinge shaft 11. The diameter of the limit rod 15 is larger than the diameter of the threaded hole. A sliding hole that cooperates with the limit rod 15 is opened inside the pulling sleeve 12;

[0028] When the connecting cross plate 8 needs to be pulled to move the cylinder housing 1, the position of the pulling sleeve 12 is adjusted. After the adjustment is completed, the adjusting screw 14 is turned to adjust the overall length of the adjusting screw 14 and the pulling sleeve 12 according to the operator's height. After the adjustment is completed, the operator can pull the cylinder housing 1 by holding the outer limit rod 15 of the pulling sleeve 12, making the operation of the cylinder housing 1 more labor-saving and convenient when moving.

[0029] The adjusting assembly includes an adjusting slot 9, a movable screw 10, a hinge shaft 11 and a second fixing nut 13. An adjusting slot 9 is opened inside the connecting cross plate 8. The end of the adjusting slot 9 away from the hinge shaft 11 is located at the center of the cylinder housing 1, and the movable screw 10 is slidably sleeved inside the adjusting slot 9. One end of the pulling sleeve 12 is rotatably connected to the movable screw 10 through the hinge shaft 11. The movable screw 10 is arranged in an "I" shape. The movable screw 10 extends to the right end of the connecting screw 6 away from the cylinder housing 1 and is threadedly sleeved with a second fixing nut 13. The outer diameters of the upper and lower ends of the movable screw 10 and the second fixing nut 13 are all larger than the width of the adjusting slot 9.

[0030] When adjusting the pulling sleeve 12, the pulling sleeve 12 is rotated by the hinge shaft 11 so that the pulling sleeve 12 is perpendicular to the connecting cross plate 8, and then the angle between the pulling sleeve 12 and the cylinder housing 1 can be adjusted with the cooperation of the moving ball 5 that can slide inside the rolling groove 4, and then the fixing nut 2 13 is screwed to release the clamping fixation of the connecting cross plate 8 by the fixing nut 2 13, and the moving screw 10 can be pulled to move the moving screw 10 inside the adjusting groove 9. When the hinge shaft 11 is moved to the middle of the cylinder housing 1, the fixing nut 2 13 is screwed again so that the fixing nut 2 13 is re-clamped and fixed to the connecting cross plate 8. After the movement is completed, the fixing nut 2 13 is screwed to rotate the pulling sleeve 12 back to the side of the connecting cross plate 8, and fix it again by the fixing nut 2 13.

[0031] The limiting rod 15 on the outside of the pulling sleeve 12 is fixed with a limiting sleeve 16 on the side facing the hinge shaft 11, and the top surface of the connecting cross plate 8 is fixed with a limiting protrusion 17 that cooperates with the limiting sleeve 16 to support and limit the pulling sleeve 12. The limiting protrusion 17 is arranged in a "7" shape, and the upper top surface of the limiting protrusion 17 is arranged in an arc shape that cooperates with the pulling sleeve 12. The upper bottom surface of the limiting protrusion 17 is arranged in an arc shape that cooperates with the inner wall of the limiting sleeve 16. The top of the limiting protrusion 17 is inserted into the inside of the limiting sleeve 16. The length between the end of the limiting protrusion 17 away from the limiting sleeve 16 and the hinge shaft 11 is less than the length of the pulling sleeve 12, and the length between the end of the limiting protrusion 17 close to the limiting sleeve 16 and the hinge shaft 11 is greater than the length of the pulling sleeve 12;

[0032] When it is necessary to adjust the pulling sleeve 12, first screw the limit rod 15 so that the limit rod 15 drives the limit sleeve 16 to move outward, so that the limit sleeve 16 can be separated from the limit protrusion 17. At this time, the limit protrusion 17 releases the limit on the limit sleeve 16, and the pulling sleeve 12 can be rotated. When it is necessary to retract the pulling sleeve 12, first rotate the pulling sleeve 12 until it abuts against the top surface of the limit protrusion 17, and then rotate the adjusting screw 14 to drive the limit sleeve 16 to move and sleeve on the outside of the limit protrusion 17, so that the pulling sleeve 12 can be limited so that the pulling sleeve 12 can fit on the side of the connecting horizontal plate 8 and be fixed.

[0033] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
