Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in more detail.

The utility model provides a kind of two-stage retractor device (see Fig. 1-6, be called for short device), comprise a sliding block 1, rotation clamp 2, two rotating shafts 3, two torsionsprings 4, floating axle 5, two floating axle limitting casings 6, two Compress Springs 7 and a top shoe 8; Described rotation clamp 2 is rectangular block, and left surface has protruding switch block 24 and two steps 25, and the lower right corner is circular arc, and centre has centre bore 22; The upper surface of described switch block 24 has arc transition position 21, for contacting with floating axle 5; Described top shoe 8 homonymy has the first groove 81 and the second groove 82; Described second groove 82 has sidewall 83;

Described rotating shaft 3 one end is cylinder part, and the other end is rectangular body; Described two rotating shaft 3 symmetries are placed on lower skateboard 1, and the rectangular body of rotating shaft 3 is fixedly connected with lower skateboard 1, and the cylinder part of rotating shaft 3 is installed in the centre bore 22 rotating clamp 2, and ensure that rotating clamp 2 can rotate around rotating shaft 3; Two torsionsprings 4 are arranged on the cylinder part of a rotating shaft 3 separately, and the rectangular body of rotating shaft 3 is fixed in one end of torsionspring, and the other end is fixed on and rotates clamp 2 place; When rotating clamp 2 and rotating, torsionspring 4 plays the effect stoping and rotate clamp 2 and rotate; Described floating axle 5 two ends are rectangular body, and centre is cylinder part; Described arc transition position 21 contacts with the cylinder part of floating axle 5, and the radian of the cylinder part of floating axle 5 is identical with the radian of arc transition position 21; The cylinder part of described floating axle 5 is arranged in the first groove 81 of top shoe 8, can move in the first groove 81 along vertical plane; A lower spring limited block 51 is respectively had above two rectangular bodies of described floating axle 5; The sidewall 83 of described top shoe 8 is respectively fixedly connected with a floating axle limitting casing 6, two floating axle limitting casing 6 symmetries by screw and places; Described two floating axle limitting casings 6 have a upper spring retainer block 61 separately, and just right with the lower spring limited block 51 separately; Two Compress Springs 7 lay respectively between floating axle limitting casing 6 and floating axle 5, and by lower spring limited block 51 and upper spring retainer block 61 fixed position, ensure that Compress Spring 7 can only stretch along vertical plane; The degree of depth of described second groove 82 is not less than the thickness of switch block 24, and its width is identical with the width of switch block 24, ensures that switch block 24 can slide in the second groove 82; When rotating clamp 2 and rotating 90 °, two sidewalls 83 contact with two steps 25 respectively.

Operation principle and the process of the utility model two-stage retractor device are: in an initial condition, and whole device is in original position (see Fig. 1).External connection power source provides power, drives whole device to travel forward.When external connection power source promotes top shoe 8, top shoe 8 drives floating axle limitting casing 6, and floating axle limitting casing 6 drives floating axle 5, floating axle 5 drives and rotates clamp 2, rotate clamp 2 and drive rotating shaft 3, rotating shaft 3 drives lower skateboard 1 together to travel forward, and whole like this device will entirety travel forward.When lower skateboard 1 motion puts in place, the motion of lower skateboard 1 is stopped by the external world, its stop motion, so far completes one-level and stretches.Due to lower skateboard 1 stop motion, coupled rotating shaft 3 also stop motion.Because top shoe 8 is still using forward under the drive of external power source, so under the effect of floating axle 5, rotate clamp 2 and start to rotate.Before rotation clamp 2 rotates, upper surface 23 contacts with top shoe 8, and along with top shoe 8 moves forward, rotate clamp 2 and turn to 90 °, switch block 24 rotates clamp 2 after contacting with the second groove 82 of top shoe 8 and stops operating.When rotating clamp 2 and turning to 45 ° from 0 °, become large owing to rotating clamp 2 vertical direction thickness, so floating axle 5 moves upward, and Compress Spring 7 is compressed; When rotating clamp 2 and turning to 90 ° from 45 °, rotate clamp 2 vertical direction less thick, floating axle 5 Compress Spring 7 and its deadweight moved downward and get back to original height.After rotation clamp 2 turns to 90 °, the switch block 24 rotating clamp will enter in the second groove 82 of top shoe 8.Now, floating axle 5 no longer plays a role in promoting to rotation clamp 2, and top shoe 8 just can move forward in the movement direction, lower skateboard 1 stop motion.In the process that top shoe 8 moves forward, the switch block 24 rotating clamp 2 slides in the second groove 82 of top shoe 8.The upper surface 23 rotating clamp 2 is larger than switch block 24 size in the direction of the width, and sidewall 83 stops rotation clamp 2 to rotate by two steps 25, rotate clamp 2 to turn round because of the effect of torsionspring 4, the attitude of 90 ° can be kept until action completes always, so far complete secondary and stretch.

When external connection power source drives top shoe 8 back to move, lower skateboard 1, rotation clamp 2, rotating shaft 3, torsionspring 4 maintain static, and the switch block 24 rotating clamp 2 slides in the second groove 82 of top shoe 8.When arc transition position 21 touches floating axle 5, because the sidewall 83 of top shoe 8 is no longer to rotation clamp 2 position-limiting actions, therefore rotation clamp 2 turns round 90 ° under the effect of torsionspring 4, and floating axle 5 experiences the process first rising and decline again simultaneously.After rotation clamp 2 turns round 90 °, top shoe 8 just can drive rotation clamp 2, rotating shaft 3, torsionspring 4 and lower skateboard 1 to get back to initial point.

Utility model is not addressed part and is applicable to prior art.
