Description

Technical Field

[0001] The utility model relates to the field of springs, in particular to an anti-tilt spring. Background Technique

[0002] A spring is a mechanical part that uses elasticity to work. Generally made of spring steel. Its elasticity can be used to control the movement of machine parts, relieve impact or vibration, store energy, measure the magnitude of force, etc.

[0003] Patent publication number CN213954217U discloses an anti-tilt spring, belonging to the technical field of springs, including a spring body. A fixed bottom plate is arranged below the spring body. An anti-tilt outer column is connected above the fixed bottom plate and at the middle position inside the spring body. A second accommodation groove is opened inside the anti-tilt outer column. An anti-tilt inner column is slidably connected inside the second accommodation groove. A guide column is connected to the bottom inside the second accommodation groove. A first accommodation groove is opened inside the anti-tilt inner column at a position corresponding to the guide column. By setting the anti-tilt inner column, the first accommodation groove, the anti-tilt outer column, the guide column, the second accommodation groove, the limit sliding ring, the limit sliding groove, the fixed bottom plate and the detachable top plate, and with the mutual cooperation of these structures, the utility model realizes the function of anti-tilt while ensuring the normal operation of the spring body, and avoids the situation that the spring body tilts during use. However, the following problems still exist in the actual use of this patent:

[0004] The anti-tilt spring enhances the anti-tilt effect of the spring by setting the anti-tilt inner column, the anti-tilt outer column and the guide column. However, when the spring contracts, the maximum contraction amount is affected by the contraction lengths of the anti-tilt inner column and the anti-tilt outer column, resulting in the length after contraction being half of the elongation length, thus leading to a small contraction amount of the spring. And the spring realizes the disassembly and assembly of the spring through structures such as a square rotating rod, a driving gear, a limit rotating ring, a limit block, and a positioning groove. However, due to the complexity of this structure, the production cost of the spring is relatively high, and the installation is relatively inconvenient. Therefore, the practicality of the anti-tilt spring is poor.

[0005] An anti-tilt spring is proposed to facilitate solving the problems raised above. Content of the Utility Model

Consequently, the contraction amount of the spring is small. Moreover, the spring uses structures such as a square rotating rod, a driving gear, a limiting rotating ring, a limiting block, and a positioning groove to achieve the disassembly and assembly of the spring. Due to the complexity of this structure, the production cost of the spring is high, and the installation is relatively inconvenient. Therefore, the practicality of the anti-tilt spring is poor.
