Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but can not be used for limiting scope of the present utility model.
Embodiment one
nullThe stereochemical structure of this utility model retractor device is as depicted in figs. 1 and 2，Its detonation configuration is as shown in Figure 3，Its plan structure is as shown in Figure 4，This retractor device includes outer tube 1，It is sleeved on the interior pipe 2 in outer tube 1 and the lining 3 being arranged between outer tube 1 and interior pipe 2，One end of interior pipe 2 is stretched out outside outer tube 1，The inner surface of outer tube 1 is provided with chute 11，The outer surface of lining 3 is provided with the slide block 31 slided along chute 11，One group of retaining mechanism it is provided with between interior pipe 2 and lining 3，This group retaining mechanism all includes two boss abutted 5，Two boss 5 are one-body molded on the outer surface of interior pipe 2 and on the inner surface of lining 3 respectively，Gap is left between boss and the inner surface (inner surface except boss) of lining 3 of interior pipe 2，Gap is left between boss and the outer surface (outer surface except boss) of interior pipe 2 on lining 3，Two boss 5 abut under the relatively rotating of outer tube 1 and interior pipe 2 or separate.
Interior pipe 2 offers bar-shaped trough 21 along the circumferential direction, lining 3 is provided with the traveller (not shown) slided along bar-shaped trough 21, the rotational angle of restriction inner and outer pipe, it is to avoid stuck phenomenon occur because rotating excessive.
Above-mentioned lining 3 is involuted by two and half linings 32, and each half lining is provided with traveller, and relatively, on interior pipe, corresponding bar-shaped trough is also two, it is simple to the installation of lining；Above-mentioned slide block 31 is two pieces, is separately positioned on two and half linings, and relatively, on outer tube, corresponding chute is also 2, it is ensured that two and half linings all relatively rotate with interior pipe.
The lower inner of outer tube 1 is set with positioning sleeve 4, and positioning sleeve 4 is arranged at the underface of lining 3, the extension elongation of pipe in restriction, it is to avoid interior pipe completely disengages from outer tube.
Outer tube 1 offers hole 12, location, positioning sleeve 4 is provided with the locating dowel 41 snapped in hole 12, location, it is simple to the installation location of positioning sleeve.
Also integrally formed with boss 5 on positioning sleeve 4, boss 5 on this positioning sleeve 4 is resisted against the boss of interior pipe 2, and and leave gap between the outer surface (outer surface except boss) of interior pipe, lock together with also being formed between interior pipe, double locking, improves coupling mechanism force.
Boss 5 is the voussoir arranged in the axial direction, it is possible to for the arc convex arranged in the axial direction, two boss can be a voussoir, an arc convex, or can be two voussoirs being crisscross arranged, or can be two arc convex.
During work, relatively rotating by inner and outer pipes, drive and relatively rotate between lining and interior pipe, two boss are made to be separated from each other, after separation, interior pipe can freely accessible for flexible, after extension elongation regulates, only need inner and outer pipe to relatively rotate certain angle, make two boss abut and just can realize locking.This utility model decreases parts, it is to avoid parts are lost, and only namely need to can lock or unlock retractor device by rotation, easy to operate.
