Description

Technical Field

[0001] The utility model relates to the technical field of tension springs, in particular to a high-stress, corrosion-resistant and deformation-resistant tension spring. Background Art

[0002] High stress, corrosion-resistant and anti-deformation tension springs are a type of high-performance springs, mainly used in applications that have extremely high requirements for material strength, corrosion resistance and stability. This type of spring is usually used in harsh environments such as chemical equipment, aerospace, marine engineering, medical equipment and other fields;

[0003] Currently, most of the hooks used to connect the existing tension springs are open, and the openings of the open hooks do not have a closed blocking function, so that the tension springs are not firmly installed and connected. When the tension springs are used in a vibration or impact environment, the tension springs are prone to sudden loosening when subjected to force, causing the tension springs to lose their function, affecting the normal operation of the equipment, and making the tension springs unreliable. In addition, the open hooks have poor sturdiness and are prone to breakage or deformation when subjected to large loads, shortening the service life of the tension springs. Utility Model Content

[0004] The purpose of the utility model is to provide a high-stress, corrosion-resistant and deformation-resistant tension spring to solve the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-stress, corrosion-resistant and deformation-resistant tension spring, comprising a spring body, a connecting assembly and a hook, the connecting assembly comprising a first connecting end block and a second connecting end block, the first connecting end block and the second connecting end block are respectively fixedly connected to the two ends of the spring body, the spring body, the connecting assembly and the hook are made of nickel-based alloy material, so that the tension spring has good corrosion resistance, performs well in high temperature and corrosive environments, can resist the erosion of various acids, alkalis and salts, and can be used in extremely harsh chemical and high temperature environments, the hook is arranged at the end of the connecting assembly away from the spring body, and the end of the hook close to the connecting assembly is connected to a connecting seat, the first connecting end block and the second connecting end block are respectively provided with movable grooves, the movable A movable disk is embedded in the interior of the groove, and the movable disk is fixedly connected to the connecting seat. The outer wall of the movable disk is fixedly connected to a slider, and the inner wall of the movable groove is provided with a slide groove used in conjunction with the slider. Through the cooperation of the movable disk, the movable groove, the slider and the slide groove, the movable connection of the hook can be achieved. When in use, the hook can rotate 360 ​​degrees, allowing the tension spring to rotate freely in any direction, so that the tension spring can adapt to a variety of different application environments and load directions. No matter from which direction the tension is applied, the tension spring can naturally adjust its position to ensure the best stretching effect. In addition, the direction of the tension may change with the movement of the equipment. The rotating hook can reduce the stress concentration caused by the change in the direction of the tension, thereby reducing the risk of the tension spring breaking or failing.

[0006] The upper end surface of the second connecting end block is fixedly connected with a fixed connecting rod, the interior of the fixed connecting rod is plugged with a movable connecting rod, and one end of the movable connecting rod away from the fixed connecting rod is connected to the first connecting end block.

[0007] Specifically, through the cooperation of the fixed connecting rod and the movable connecting rod, the outside of the spring body can be supported, ensuring that the spring body maintains linear motion when subjected to force, reducing lateral deviation or swinging, thereby improving the stability of the tension spring during operation. In addition, it also avoids the situation where the spring body is in a swinging state for a long time and deforms.

[0008] Preferably, an elastic closing structure is provided at the opening of the hook, and the elastic closing structure includes a connecting sleeve fixedly connected to the outer wall of the hook, the outer wall of the connecting sleeve is fixedly connected to a connecting frame, the interior of the connecting frame is hinged with a stopper, the outer side wall of the stopper is connected to a compression spring, and the end of the compression spring away from the stopper is connected to the connecting frame.

[0010] Through the above technical solution:

[0011] When connecting, first press one end of the block toward the inside of the hook. At this time, the blocking block moves out of the slot opened by the fixed block, and the hook opening can be opened. After connection, release the pressed blocking block, and use the elastic force of the compression spring to move one end of the block toward the fixed block until the blocking block is stuck in the slot. This operation can improve the hook from an open type to a closed type, ensuring the firmness of the tension spring after installation and connection, preventing the tension spring from suddenly loosening when used in a vibration or impact environment, ensuring that the tension spring can maintain a stable connection when in use, effectively reducing the chance of the tension spring loosening when subjected to tension, enhancing the reliability of the tension spring when in use, and not affecting the normal operation of the equipment.

[0014] Through the above technical solution:

[0015] When the hook is worn, first take a flat-blade screwdriver and insert one end of it into the flat-blade groove on the surface of the outer ring block, then rotate the flat-blade screwdriver to drive the threaded rod to rotate. During the rotation, the embedded block gradually moves out of the embedded groove and is retracted into the block groove. Finally, pull out the hook and the installation plug-in block moves out of the installation slot. This operation can quickly remove the worn hook, and then perform the above operation in reverse to install a new one, which enhances the convenience of replacing the hook, eliminates the need for special disassembly and assembly tools, and reduces the difficulty of replacement.

[0016] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0017] 1. By setting up an elastic closed structure, the opening of the hook has a closed function. When in use, the open hook can be improved to a closed type, which ensures the firmness of the tension spring after installation and connection, prevents the tension spring from suddenly loosening when used in a vibration or impact environment, ensures that the tension spring can maintain a stable connection during use, effectively reduces the probability of the tension spring loosening when subjected to tension, enhances the reliability of the tension spring during use, and does not affect the normal operation of the equipment. In addition, the closed hook can disperse stress when bearing a large load, making it less likely for the hook to break or deform, thereby extending the service life of the tension spring;

[0018] 2. By setting up a disassembly and assembly structure, the connection of the hook has a disassembly and assembly function. When the hook is worn, the worn hook can be quickly removed and replaced with a new one. This solves the problem that the existing hook is fixed by welding, which requires the replacement of the entire tension spring after the hook is worn, resulting in waste of other parts of the tension spring.
