Description

TECHNICAL FIELD

[0001] The utility model relates to spring mounting technical field, concretely is a kind of installation structure for spring. BACKGROUND

[0002] Spring is a kind of mechanical part using elasticity to work. It will be deformed under the action of external force, and when the external force is removed, spring can restore original state. Spring is usually made of elastic material, such as spring steel. These materials can be deformed when subjected to external force, and quickly restore their original shape after the external force is removed. Spring is fixed and installed by mounting structure, and spring mounting structure is usually composed of spring itself, mounting bracket, connecting piece, limiting piece and other structures. Usually, spring is directly placed on mounting bracket, and fixed by connecting piece.

[0003] For example, the Chinese patent "Spring fixing structure" with announcement number CN210240397U includes spring, fixed pressing sheet, connecting plate and fastener. The fixed pressing sheet connects the spring to one side of the connecting plate through the fastener. The fixed pressing sheet has extending arc edges outward along the circumference. The extending arc edges are in close contact with the surface of the spring when working and press the spring tightly on the connecting plate. The cross section of the extending arc edge is semicircular. The number of extending arc edges is one or more. The fixed pressing sheet is provided with a first mounting hole in the center. The fastener is connected with the connecting plate through the first mounting hole. The connecting plate is provided with a second mounting hole. The fastener is connected with the fixed pressing sheet through the second mounting hole. The second mounting hole is at least one. The fixed pressing sheet is formed by die stamping once. The fastener includes bolt and nut.

[0004] The above-mentioned prior art can realize the installation of spring, but in actual use, on the one hand, the position of clamping mechanism is difficult to adjust. Usually, the clamping mechanism is fixedly arranged, which makes it difficult for the clamping mechanism to clamp springs of different sizes, thereby reducing the adaptability of the clamping mechanism. On the other hand, the spring is prone to shaking during extension and contraction. Usually, the spring is independently arranged on the mounting structure, which makes the spring prone to shaking under the action of external force, thereby affecting the use effect of the spring. Therefore, it does not meet the existing requirements. To solve this problem, we propose a kind of installation structure for spring. UTILITY MODEL CONTENTS
