Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder accessories, in particular to an oil cylinder steering structure. Background Art

[0002] Cylinder usually refers to hydraulic cylinder, also known as hydraulic piston. Hydraulic cylinder is a device that uses hydraulic pressure to generate mechanical motion. It usually consists of a piston, a piston rod, seals, cylinder body and pipelines. When hydraulic fluid is pumped into the hydraulic cylinder, the piston is pushed by pressure, thereby generating linear motion or rotational motion, thereby driving the mechanical system to complete the required task. The steering structure of the cylinder can convert linear motion into motion in other directions, such as rotational motion. This can achieve a wider range of applications and meet the needs of different engineering and mechanical systems. A rack is provided on one side of the cylinder piston rod that is meshed with a pair of gears. When the piston rod of the cylinder drives the rack to retract or eject, the rack can only drive a pair of gears to rotate synchronously in the reverse or forward direction. Such a cylinder steering structure is too simple, so that the rotation direction of a pair of gears cannot achieve different mechanical motions, resulting in the inability of this hydraulic steering structure to respond flexibly in various working conditions.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-2As shown, a cylinder steering structure proposed by the utility model includes a cylinder body 1, a first gear 8 and a second gear 9. The end of the cylinder body 1 away from the piston rod is fixedly connected with a flange for fixing the cylinder body 1. The flange is used to mount the cylinder body 1 on the equipment. The corresponding side surfaces of the first gear 8 and the second gear 9 are fixedly connected with a shaft 891. The function of the shaft 891 is to drive the corresponding shaft 891 to rotate through the rotating first gear 8 and the second gear 9. The rotating shaft 891 can drive the corresponding equipment to run, and the shaft 891 can be installed on the two end surfaces of the first gear 8 and the second gear 9 according to the required use. It also includes: a transmission mechanism installed on the piston rod of the cylinder body 1, which makes the first gear 8 and the second gear 9 rotate synchronously by retracting. After the piston rod on the cylinder body 1 is ejected, the first gear 8 rotates forward and the second gear 9 rotates reversely through the transmission mechanism; a limiting mechanism is arranged at the end of the transmission mechanism away from the cylinder body 1 to limit the transmission mechanism from moving along a fixed trajectory.

[0025] Further, the transmission mechanism includes a first connection block 2 fixedly connected to the piston rod of the oil cylinder body 1, and the first connection block 2 is rotatably connected to the end of the piston rod of the oil cylinder body 1 with a rotating rod 3. The rotating rod 3 is tilted toward one end of the first connection block 2 with its middle as the center under normal conditions, and the function of the tilt is to make the rotating rod 3 automatically rotate toward the tilted end after the oil cylinder body 1 is running. The rotating rod 3 is rotatably connected to the end of the rotating rod 3 away from the first connection block 2, and the end of the second connection block 4 away from the rotating rod 3 is fixedly connected to a ladder frame 5, and the interior of the ladder frame 5 is provided with a first rack 51 and a first rack 51 meshed with the second gear 9, and the end of the ladder frame 5 away from the second connection block 4 is fixedly connected to a support rod 6, and the end of the support rod 6 away from the ladder frame 5 is provided with a third rack 61 meshed with the first gear 8.

[0026] For further information, please see Figure 3 The limiting mechanism includes a U-shaped block 7, and a connecting piece for fixing the U-shaped block 7 is provided on the U-shaped block 7. The function of the connecting piece is to fix the U-shaped block 7 on the equipment. A limiting slide groove 62 is provided on the support rod 6, and a clamping rod 71 that movably penetrates the limiting slide groove 62 is fixedly connected inside the U-shaped block 7. The clamping rod 71 cooperates with the limiting slide groove 62 to make the transmission mechanism run on the fixed track.

[0027] In this embodiment, when the oil cylinder steering structure is required, Figure 1As shown, after the oil cylinder body 1 is started, the piston rod on it is pushed out and drives the first connecting block 2 to move. The first connecting block 2 pushes the rotating rod 3 to move. Since the rotating rod 3 is tilted toward the first connecting block 2 with its middle as the center, the first connecting block 2 pushes the rotating rod 3 to rotate in the tilted direction. At the same time, the end of the rotating rod 3 away from the first connecting block 2 pushes the second connecting block 4 to move. The second connecting block 4 pushes the ladder frame 5 to rotate around the clamping rod 71 in the upper limit slot 62 of the support rod 6. The rotated ladder frame 5 will drive the first rack 51 therein to press against the second gear 9. Since the second gear 9 is meshed and connected with the first rack 51, the first rack 51 drives the second gear 9 to rotate in one direction. At the same time, since the third rack 61 is spirally connected to the first gear 8, the third rack 61 drives the first gear 8 to rotate toward the other end. Finally, the first gear 8 and the second gear 9 both drive the shaft 891 thereon to rotate in opposite directions. As shown Figure 2 As shown, when the oil cylinder body 1 is running, the piston rod on it is retracted and drives the first connecting block 2 to move, and the above operation is reversed, which will not be repeated here. Figure 2 The status shown is restored to Figure 1 In the state shown, the second rack 52 in the ladder frame 5 is meshed with the second gear 9, and the second rack 52 drives the second gear 9 and the third rack 61 drives the first gear 8 to rotate in the same direction.
