Problems solved by technology
[0002] Common telescopic mechanisms often use a single ordinary cylindrical spring to achieve telescopic action and flexible support, but the ratio of the length of the ordinary cylindrical spring after compression to its free state is relatively large, so that the entire expansion and contraction after full compression will occupy a lot of axial space , and in the case of small installation space, the telescopic mechanism composed of a single ordinary cylindrical spring will be limited, and the stroke of the ordinary cylindrical spring is not variable, so it is not suitable for occasions that require a long stroke

Embodiment Construction
[0017] 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.
[0018] Such as Figure 1 to Figure 5 As shown, an automatic guiding telescopic mechanism described in this embodiment includes a first-stage sleeve 1, a second-stage sleeve 2, a third-stage sleeve 3, and a guide cylinder 4, all of which are hollow cavity structures. The first-stage sleeve 1, the second-stage sleeve 2, and the third-stage sleeve 3 are respectively provided with a first-stage cone spring 5, a second-stage cone spring 6, and a third-stage cone spring 7. The upper end of the stage cone spring 5 abuts against the second stage sleeve 2, the upper end of the second stage cone spring 6 abuts against the third stage sleeve 3, and the upper end of the third stage cone spring 7 contacts the guide cylinder 4 Backing, the second-level sleeve 2 is sleeve...

The invention discloses an automatic guiding telescopic mechanism, which comprises a first-stage sleeve, a second-stage sleeve, a third-stage sleeve and a guide cylinder all of which are hollow cavity structures, the first-stage sleeve, the second-stage sleeve The first-stage cone spring, the second-stage cone spring, and the third-stage cone spring are respectively arranged in the sleeve and the third-stage sleeve, and a three-position four-way solenoid valve is also provided at the upper end of the guide cylinder; Through the air intake and exhaust of the solenoid valve, the air pressure in the guide cylinder, the third-level sleeve, the second-level sleeve and the first-level sleeve is changed in turn to realize the multi-stage automatic expansion and contraction process. The structure is more flexible, thereby reducing The telescopic mechanism takes up the size of the axial space and can provide a larger stroke, and the first-stage conical spring and the second-stage conical spring are respectively arranged in the first-stage sleeve, the second-stage sleeve and the third-stage sleeve And the third-stage cone spring to achieve flexible support and further save space, which can meet the occasions where the installation space is limited.
Description
technical field [0001] The invention relates to an automatic guiding telescopic mechanism and a telescoping method. Background technique [0002] Common telescopic mechanisms often use a single ordinary cylindrical spring to achieve telescopic action and flexible support, but the ratio of the length of the ordinary cylindrical spring after compression to its free state is relatively large, so that the entire expansion and contraction after full compression will occupy a lot of axial space , and in the case of small installation space, the telescopic mechanism composed of a single ordinary cylindrical spring will be limited, and the stroke of the ordinary cylindrical spring is not variable, so it is not suitable for occasions that require a long stroke. [0003] Therefore, there is an urgent need to provide a telescopic mechanism that not only occupies a small axial space but can provide a long stroke. Contents of the invention [0004] The object of the present invention ...
