Embodiment
A kind of rotary mode list draws take-up mechanism, as shown in Figures 1 to 4, comprises disc housing 10 and the rotating mould 20 and the saucerspring 30 that are placed in the housing 10; Described housing 10 comprises mutually adaptive drain pan 11 and loam cake 12, forms centralized positioning axle 121 on the described drain pan 12, has the hole 201 suitable with described locating shaft 121 on the described rotating mould 20.Have through wires hole 202 on the described rotating mould 20, the avris of described housing is provided with two wire holes 101,102.Described rotating mould 20 upper ends form coiling annular wall 21, described saucerspring 30 is placed in the described annular wall 21, and the interior root and the described locating shaft 121 of saucerspring 30 are connected and fixed, establish spring bumper cover 40 in saucerspring 30 upper end covers again, be in all the time in the described annular wall 21 to guarantee saucerspring 30.Described rotating mould 20 lower ends form ratchet-like boss 22 and roll 23, and these ratchet-like boss 22 circumference evenly are provided with 6 positioning tooths 221.On the described drain pan 11, be symmetrically installed with two stop parts 50 of movable adjusting in the dual-side of circumference, this stop part 50 is suitable with described positioning tooth 221; In the utility model, stop part 50 concrete mounting meanss are: as Fig. 2 and shown in Figure 4, be installed on the described drain pan 11 by bearing pin 51 and torque spring 52, and add button 60 in outboard end, do not press the button 60 o'clock, the end points of described stop part 50 props up described positioning tooth 221, thereby rotating mould 20 can only be rotated (with reference to direction shown in Figure 2 by a direction, be that rotating mould 20 can only be by counterclockwise rotating, and clockwise direction is prevented from, and the direction that the back narration relates to is reference with direction shown in Figure 2 all).
During this use was novel, wire rod is divided into three sections: one, active segment 91, were used for stretching or rolling, with the needs that satisfy various different lengths be convenient to collection and carry; Two, canned paragraph 92, can not be stretched, and are used to patch signal source or power supply; Three, the transition linkage section 93, are used to connect active segment 91 and canned paragraph, and active segment 91 stretch or the process of rolling in, play the effect of the room for maneuver, avoid wire rod stretch or the process of rolling in reversed and influenced the effect of folding and unfolding.Described active segment 91 is wound on the coiling annular wall 21 of described rotating mould 20 upper ends, the external end head of described active segment 91 stretches out outside mechanism's housing through a wire hole 101, described through wires hole 202 is passed in the inner of active segment 91, be connected with the transition linkage section 93 on being wrapped in described rotating mould 20 lower end rolls 23, the other end of this transition linkage section 93 is connected with the inner of described canned paragraph 92, and the external end head of canned paragraph 92 stretches out outside mechanism's housing through another wire hole 102.In order further to guarantee that wire rod 90 is more smooth in the folding and unfolding process, also be provided with wire-blocking board 80, have the hole 81 suitable on this wire-blocking board 80 with described centralized positioning axle 121.Described active segment 91 also can be a complete wire rod with transition linkage section 93, transition linkage section 93 is equivalent to active segment 91 a Design of length segment length wire rod of back reservation well, active segment 91 is passing described through wires hole 202 after the winding on the coiling annular wall 21 again, that length of wire (being transition linkage section 93) of reserving is wrapped on the described roll 23, and the section of being connected and fixed 92 again.As Fig. 2 and shown in Figure 4, described transition linkage section 93 can be connected by corresponding plastic cement adaptor 94 according to needs such as wire rod types with canned paragraph 92.Certainly, in particular cases, described three sections wire rods also can adopt a complete wire rod.
Shown in Fig. 3,4, after installing, the centralized positioning axle 121 on the described drain pan 11 passes hole 41 on hole 201 on the rotating mould 20, saucerspring 30, the spring bumper cover 40 and the hole 81 on the wire-blocking board 80 from bottom to top successively.
As shown in Figure 1 and Figure 4, in the utility model, cover on described, be provided with annular ornamental strip 13.Strengthen the aesthetic of product.
The wire rod (being active segment 91) that is wound on the described coiling annular wall 21 can stretch and regain, and its length can design arbitrarily according to concrete needs.The relative active segment of the length of transition linkage section 93 91 is shorter.In conjunction with shown in Figure 2, during use, the user is according to the length needs, and pulling active segment 91 drives described rotating mould 20 by rotation counterclockwise, and described saucerspring 30 is compressed.Can stop drag after pulling out the appropriate length wire rod, at this moment, positioning tooth 221 on the rotating mould 20 is propped up by the end points of stop part 50 (because the effect of torque spring 52 is arranged, under the effect that does not have external force, the circumference that the end points of stop part 50 remains to ratchet-like boss 22 is close to), the elastic force of saucerspring 30 is overcome, and rotating mould 20 can not be refunded rotation along clockwise direction, so wire rod can not be retracted.After finishing using, the user presses the button 60, described stop part 50 rotates around described bearing pin 51, make the end points of described stop part 50 break away from described positioning tooth 221, under the elastic force effect of described saucerspring 30, described rotating mould 20 is rotated in a clockwise direction, and drives wire rod (active segment 91) and is retracted in the mechanism.In the process of the stretching of active segment 91 and withdrawal, unclasping and the motion of crispaturaing back and forth done in the rotation that described transition linkage section 93 is also followed rotating mould 20, play room for maneuver effect, effectively avoid wire rod stretch or the process of rolling in reversed and influenced the effect of folding and unfolding.
In the utility model, described positioning tooth 221 evenly is provided with 6 along circumference, that is to say can be the length of a gear stretching or contraction wire by per 1/6 circumference of boss 22, can satisfy various needs fully.Certainly, also can 8 or other number positioning tooths evenly be set, perhaps design the ratchet-like boss of different circumferential lengths according to concrete needs.Stop part 50 is symmetrical arranged two, makes controlling of stretching or contraction location more reliable.
