Embodiment
Directly be respectively the embodiment of one group of metal telescopic tube quickly retracting device of φ 30mm and φ 35mm below in conjunction with accompanying drawing and 2-section pipe, the present invention is described further.The present invention is not limited to the quickly retracting of two joint telescopic tubes, in the caliber scope of φ 18mm～φ 35mm, all can be by structure of the present invention, and one group at per two joints of metal tube that the more piece caliber is successively decreased gradually link into an integrated entity through a cover the present invention.
Like Fig. 1～shown in Figure 3; Present embodiment comprises that the interior pipe 1 of φ 30mm caliber, the outer tube 2 of φ 35mm caliber, flexible detent mechanism 3 of interior pipe and the interior pipe that is arranged on interior pipe 1 one ends stretch out position-limit mechanism 4; Interior pipe 1 is enclosed within the outer tube 2; In pipe 1 lower end be provided with the interior pipe straight trough 11 on pipe 1 axial symmetrical centre plane in a pair of the passing, outer tube 2 upper ends are provided with an outer tube straight trough 21 corresponding with interior pipe straight trough 11.The flexible detent mechanism 3 of interior pipe comprises a pair of location calvus 31, stage clip 32 and location calvus back shaft 33; In pipe 1 lower end, the major diameter of pipe 1 and location calvus back shaft 33 was fixedly connected with interior pipe 1 to rivet 6 with two minor axis to rivet 5 and is integral in crossing through 1 respectively in location calvus back shaft 33 was fixed on.Have axial groove 331 on the axial symmetrical centre plane of calvus back shaft 33 upper ends, location; A pair of location calvus 31 is arranged in the axial groove 331 symmetrically; Calvus lower end, location becomes Z-shaped; Calvus 31 upper ends, location are hinged through rivet with calvus back shaft 33 upper ends, location, and stage clip 32 is arranged on the middle inside of a pair of location calvus 31.When interior pipe 1 is pulled out the location; Pipe straight trough 11 overlaps with an outer tube straight trough 21 positions in one pair; Calvus 31 outsides, a pair of location are stretched out corresponding interior pipe straight trough 11 and outer tube straight trough 21 respectively; On the downside of pipe straight trough 11 and outer tube straight trough 21, interior pipe 1 was pulled out positioning states for 2 one-tenth with outer tube in Z-shaped breach 311 was resisted against.
Interior pipe stretches out the upper end that position-limit mechanism 4 is arranged on the flexible detent mechanism 3 of interior pipe, comprises the radially connection rivet 41 fixed connection outer ring bodies 42 and outer tube 2 that 3 42,3 of radially connection rivet 41, outer ring bodies that are uniformly distributed with are uniformly distributed with.Setting circle diameter D between the endoporus that radially connects the inner termination protrusion outer tube 2 of rivet 42,3 inner terminations that radially connect rivet 42 is greater than interior external diameter of pipe d.Tube shoulder 12 in radially extending on interior pipe 1 outer peripheral face, said interior tube shoulder 12 external diameter B are greater than the setting circle diameter D between the inner termination that radially connects rivet 32.Break away from outer tube 2 when pipe 1 was pulled out in such structure can prevent.
Interior pipe 1 outer moving when pulling out the location; Pipe straight trough 11 outer moving in one pair; Until overlapping with an outer tube straight trough 21 positions, under the effect of stage clip 32, calvus 31 outsides, a pair of location are stretched out corresponding interior pipe straight trough 11 and outer tube straight trough 21 respectively; On the downside of pipe straight trough 11 and outer tube straight trough 21, interior pipe 1 was pulled out positioning states for 2 one-tenth with outer tube in the Z-shaped breach 311 of location calvus 31 was resisted against.
When interior pipe 1 is withdrawn; Earlier with the outer again segment distance that draws of interior pipe 1; Make the Z-shaped breach 311 of location calvus 31 break away from outer tube straight trough 21 downsides; In the process that interior pipe 1 moves; Outer tube straight trough 21 upsides promotion location calvus 31 overcomes the elastic force of stage clip 32 and compresses into pipe straight trough 11; Interior pipe 1 is rotated 45 ° and be pushed down in the outer tube 2, pipe 1 is reduced in the outer tube 2 fully in making again.The interior pipe 1 of present embodiment and the length of outer tube 2 are 1380 mm, and when interior pipe 1 was pulled out the location, 2-section pipe length can reach 2615mm; When interior pipe 1 was withdrawn, length was 1480mm after the long contraction of 2-section pipe.
The present invention both can be used for the quickly retracting of the metal sleeve that the more piece fit stretches in the whip antenna, also can be used for other and needed the flexible metal sleeve of more piece fit or the quickly retracting of non-metallic casing.
Except that the foregoing description, the present invention can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
