Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.
[0016] Such as Figure 1 to Figure 4 As shown, a three-stage spring telescopic mechanism described in this embodiment includes a first-stage sleeve 1, a first-stage spring 2, a first-stage retaining ring 3, a second-stage sleeve 4, and a second-stage spring 5 , the second stage retaining ring 6, the third stage sleeve 7, the third stage spring 8, the third stage retaining ring 9 and the guide cylinder 10, the first stage spring 2 is arranged in the first stage sleeve 1, so The lower end of the second-stage sleeve 4 extends into the first-stage sleeve 1, and the two ends of the first-stage spring 2 respectively abut against the first-stage sleeve 1 and the second-stage sleeve 4. The primary retaining ring 3 is fixed on the upper end of the first-stage sleeve...

The invention discloses a three-level spring extension-retraction mechanism. The mechanism comprises a first-level sleeve, a first-level spring, a first-level check ring, a second-level sleeve, a second-level spring, a second-level check ring, a third-level sleeve, a third-sleeve spring, a third-sleeve check ring and a guide cylinder. The first-level spring is arranged in the first-level sleeve, the lower end of the second-level sleeve extends into the first-level sleeve, the two ends of the first-level spring abut against the first-level sleeve and the second-level sleeve respectively, the second-level spring is arranged in the second-level sleeve, the lower end of the third-level sleeve extends into the second-level sleeve, the two ends of the second-level spring abut against the second-level sleeve and the third-level sleeve respectively, the third-sleeve spring is arranged in the third-level sleeve, the lower end of the guide cylinder extends into the third-level sleeve, and the two ends of the third-level spring abut against the third-level sleeve and the guide cylinder respectively. According to the three-level spring extension-retraction mechanism, the area of the axial space occupied by the spring extension-retraction mechanism can be greatly reduced, the larger stroke is provided, and the mechanism is suitable for occasions with the limited mounting space.
Description
technical field [0001] The invention relates to a three-stage spring telescopic mechanism. Background technique [0002] After the ordinary spring is compressed, because the spring itself will occupy the axial space, the installation occasions will be limited, and the stroke of a single spring cannot be adjusted, which cannot meet the need for a large stroke. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a three-stage spring telescopic mechanism. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] A three-stage spring telescopic mechanism, comprising a first-stage sleeve, a first-stage spring, a first-stage retaining ring, a second-stage sleeve, a second-stage spring, a second-stage retaining ring, a third-stage sleeve, a first-stage The three-stage spring, the third-stage retaining ring and the guide sleeve, the first-stage spring ...
