Description

Technical Field

[0001] The utility model relates to the technical field of cylinders, in particular to a thin self-locking structure of a cylinder with a guide rod. Background Art

[0002] The thin guide rod cylinder is a compact pneumatic actuator with the characteristics of simple structure and small size. It is usually composed of components such as guide rods, cylinder barrels, pistons, seals and end covers. The overall design is compact, which enables the guide rod thin cylinder to provide efficient linear motion control in a limited installation space. It is suitable for application scenarios with limited installation space and requiring less vibration. Secondly, the pneumatic automation accessory guide rod thin cylinder has high-precision and stable motion control capabilities. It uses a guide rod to guide the movement of the piston, so that the piston has less swing and jitter during operation, achieving more precise and stable motion control. This makes the guide rod thin cylinder perform well in industrial automation applications that require precise positioning or require less vibration. Guide rod thin cylinders are widely used in automation systems in various fields, including automation equipment, machine tool manufacturing, industrial production and other fields.

[0003] At present, when a thin cylinder with a guide rod is used to lift materials, the gravity of the material will be directly transmitted to the cylinder in the perpendicular direction, which may easily cause damage to the cylinder. In addition, when the power is cut off and the gas is cut off, the material will fall directly, posing a safety hazard. Therefore, we propose a self-locking structure of a thin cylinder with a guide rod. Utility Model Content

[0004] The utility model aims to provide a thin self-locking structure of a cylinder with a guide rod to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thin self-locking structure of a guide rod cylinder, comprising a first support, a cylinder body, a driving arm, a second support and a V-shaped movable component, wherein the second support is arranged on one side of the first support, the V-shaped movable component is arranged above the second support, and the bottom end of the V-shaped movable component is hinged to the second support through a second hinge shaft, the V-shaped movable component comprises a first force arm and a second force arm, the driving arm is arranged between the first support and the second support, and a carrier seat is fixed to one side of the top end of the driving arm, the cylinder body is arranged on the inner side of the driving arm, and one end of the cylinder body is hinged to the first support through a first hinge shaft, and the output end of the cylinder body is hinged to the second force arm through a third hinge shaft.

[0006] Preferably, guide rails are provided on both sides of the cylinder body, and a slider is slidably connected to the outer wall of the guide rail, and the slider is fixedly connected to the driving arm to assist the up and down movement of the driving arm.

[0007] Preferably, sliding grooves are provided on the outer walls on both sides of the driving arm to facilitate guiding and limiting the sliding rod.

[0008] Preferably, first electromagnet blocks are installed on both sides of the top end of the second support to lock the V-shaped movable component.

[0009] Preferably, sliding rods are fixed on the outer walls on both sides of the first force arm, and one end of the sliding rod extends to the inside of the sliding groove to assist the lifting and lowering work of the driving arm.

[0010] Preferably, a second electromagnet block is installed on the outer wall of one side of the second force arm, and the second electromagnet block is magnetically attracted to the first electromagnet block for positioning the V-shaped movable component.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The cylinder body is started to drive the V-shaped movable component to rotate around the second hinge axis through the second force arm. The first force arm drives the slide bar to slide along the slide groove and drives the driving arm to lift it. The driving arm drives the slider to move up along the guide rail, and the driving arm lifts the material through the carrier. After the carrier lifts the material, the gravity force of the material is in the vertical direction, and the driving force of the cylinder body is in the horizontal direction, forming an angle of ninety degrees between the two, thereby realizing a self-locking function. The gravity of the material will not damage the cylinder body, and the material will not fall in the event of power outages and gas failures, which is safer. In addition, the second electromagnet block and the first electromagnet block are energized so that the second electromagnet block and the first electromagnet block are magnetically attracted to each other, thereby further locking the V-shaped movable component to prevent it from deflecting under the action of external force. The self-locking effect is good and the reliability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
