Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen springs, in particular to a drawing device for a nitrogen spring. Background Art

[0002] A nitrogen spring is a mechanism that injects high-pressure nitrogen into a sealed cylinder and uses the reaction force of the nitrogen as a spring. The supporting force is constant throughout the entire working stroke, avoiding impact when the object is closed. It is often used for lifting, supporting, gravity balancing and other functions. It is easy to install, safe to use, and requires no maintenance.

[0003] After searching, the patent with Chinese patent application number 202322787937.5 discloses a pulling device for a nitrogen spring, including a base frame and a hydraulic rod, the hydraulic rod is connected to the top of the base frame and its output end is downward; a fixed column is connected to the rear side of the base frame, the fixed column is connected to a force plate, and the upper end of the force plate is connected to a lower clamp; a stable partition is provided in the middle of the base frame, and the top of the fixed column is connected to the stable partition; the output end of the hydraulic rod passes through the stable partition and the top of the fixed column, and the output end of the hydraulic rod is connected to an upper clamp; the hydraulic rod is equipped with a hydraulic cylinder, which is controlled by a hand crank; the upper clamp and the lower clamp mechanically fix the two ends of the nitrogen spring, and the hydraulic rod drives the mechanical movement of the upper clamp to achieve pulling, avoiding the danger of manual pulling with pliers. The upper clamp and the lower clamp set up fix the two ends of the nitrogen spring. During the pulling process, even if the piston rod has a large inertia at the moment of pulling out, the upper clamp and the lower clamp can clamp and fix it to avoid the danger of flying; mechanical pulling is more labor-saving.

[0004] The above patent has poor flexibility in the nitrogen spring pulling operation, and cannot clamp and position the nitrogen spring appropriately according to its size, resulting in poor stability in the nitrogen spring pulling operation and easy falling off. Secondly, this patent uses a hydraulic rod as a power source to directly pull the nitrogen spring. During the pulling process, it cannot ensure that the nitrogen spring is evenly stressed, nor can the pulling movement of the nitrogen spring be accurately controlled, which may cause damage to the nitrogen spring. The practicality of the device is poor.

[0005] To this end, we propose a pulling device for a nitrogen spring to solve the above problems. Utility Model Content
