Description
Technical Field
[0001] The utility model relates to the technical field of springs, in particular to an anti-scratch and anti-winding spring. Background Art
[0002] A spring is a mechanical element that stores and releases energy through elastic deformation. Springs are widely used in situations such as absorbing vibrations, buffering, storing energy, and applying force, such as automotive suspension systems, mechanical equipment, and household appliances. Common types include compression springs, extension springs, torsion springs, and conical springs. Existing compression springs have the following disadvantages in actual use: 1. When using large-scale automated assembly, the springs are very easy to get tangled, which can easily lead to incorrect clamping by the robot, affecting assembly efficiency; 2. The end faces of the springs usually have sharp metal edges, which will be exposed and directly contact the skin during installation, compression, or stretching, which can easily cause scratches on people. In view of the above problems, the existing springs are improved and optimized. Utility Model Content

[0016] As Figures 1-4 shown, the anti-scratch and anti-entanglement spring involved in the present utility model includes a spring linear unit 2 wound in a spiral shape. An expansion gap 3 is formed between adjacent spring linear units 2. Spring outer protection parts 1 are provided at both ends of the anti-scratch and anti-entanglement spring. The spring outer protection part 1 includes an inner anti-entanglement ring 4 and an outer anti-entanglement ring 5 formed by horizontally winding the spring linear unit 2 in sequence and arranged up and down. The end of the outer anti-entanglement ring 5 is bent to form a winding ring transition part 6 and then continues to wind around an arc to form an anti-scratch ring 7. The inner diameter of the inner anti-entanglement ring 4 is the same as the inner diameter of the outer anti-entanglement ring 5. The inner diameter of the anti-scratch ring 7 is larger than the inner diameter of the inner anti-entanglement ring 4. The anti-scratch ring 7 is arranged between the lower end face of the inner anti-entanglement ring 4 and the upper end face of the outer anti-entanglement ring 5. The inner anti-entanglement ring 4 and the outer anti-entanglement ring 5 provide an isolated structure at the end of the spring for the spring, reducing the possibility of entanglement between springs, facilitating correct clamping by the manipulator, being suitable for large-scale automated assembly, and effectively improving the assembly efficiency; The end of the spring is provided with an anti-scratch ring 7, which can be smoothly transitioned through the winding ring transition part 6, eliminating the sharpness of the spring hub and the end, effectively reducing the scratching risk of operators and improving safety. The anti-scratch ring is arranged not to exceed the two end faces, enabling the stable installation of the spring and not affecting the normal operation of the spring.
[0017] A clearance gap 9 is formed between the inner anti-winding ring 4 and the outer anti-winding ring 5, and the anti-scratch ring 7 is arranged at the clearance gap 9. The inner anti-winding ring 4, the anti-scratch ring 7 and the outer anti-winding ring 5 are stacked together in sequence, which makes it easier to hide the end of the spring so as not to prick the hand and optimizes the stress distribution of the spring, reduces the fatigue loss of the spring in high-frequency use, prolongs the service life, and makes the overall structure more stable and reliable.
[0018] At least one equally divided spring inner protection part 10 is provided in the middle of the anti-scratch and anti-winding spring. The inner diameter of the spring inner protection part 10 is the same as the inner diameter of the inner anti-winding ring 4, which increases the structural support of the spring, prevents the spring from deformation or dislocation, and ensures stable elastic performance.
[0019] The spring inner protection portion 10 is formed by overlapping at least two adjacent circles of the spring linear units 2, thereby enhancing the anti-winding capability of the spring interior.
[0020] The gap between the overlapping spring linear units 2 is smaller than the cross-sectional diameter of the spring linear unit 2, and the anti-winding effect is best.
[0021] The clearance gap 9 is smaller than or equal to the cross-sectional diameter of the spring linear unit 2, and the structure is more stable. If the clearance gap 9 is too large, the anti-scratch ring 7 is easy to enter the interior of the spring, affecting the positioning and installation of the spring.
[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
