Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
Single direction rotation clutch mechanism as shown in Fig. 1 ~ 2, comprise driving disc 1, from moving-coil 2 and flexible rod 3, driving disc 1 is with coaxial from moving-coil 2, and driving disc 1 is positioned at from moving-coil 2, one end of flexible rod 3 is connected with driving disc 1 elasticity, limit dais 21 is inwardly convexly equipped with from the inwall of moving-coil 2, this limit dais 21 has the sliding bevel 211 that is slidably matched with the other end of flexible rod 3 and the block face 212 for keeping out flexible rod 3 the other end, sliding bevel 211 is with crossing in obtuse angle from moving-coil 2 inwall, block face 212 is with crossing at right angles or acute angle from moving-coil 2 inwall, by being slidably matched to flexible rod 3 the other end of sliding bevel 211, the other end ordering about flexible rod 3 switches stretching out driving disc 1 outer periphery and be retracted between the position in driving disc 1.
Coordinated with keeping out of block face 212 by flexible rod 3, the moment that driving disc 1 is rotated forward under external force drives can be passed to from moving-coil 2, rotate from moving-coil 2 to drive, being slidably matched again by flexible rod 3 and sliding bevel 211, when driving disc 1 can be reversed under external force driving force, flexible rod 3 is extruded by sliding bevel 211 and stretches, now driving disc 1 dallies, thus realize single direction rotation clutch, more crucially be, because the angle of block face 212 and sliding bevel 211 is arranged, make the other end of flexible rod 3 when driving disc 1 rotates forward reliably, stably keep out with block face 212, to realize the output of larger rotation torque, and, driving disc 1 is positioned at from moving-coil 2, each parts are also positioned at from moving-coil 2, be beneficial to and the fixing fabric structure of the utility model single direction rotation clutch mechanism is obtained enough little, the occasion use that energy meeting spatial is narrow and small.
Driving disc 1 center of this example has the fixed hole 13 for driving rotation, and this fixed hole 13 can load outer buttons rotating shaft, to provide initial rotating power to driving disc 1.
As a preferred mode, the limit dais 21 of this example is set to multiple, along being spacedly distributed from the inwall circumference of moving-coil 2, sliding bevel 211 is with crossing in obtuse angle from moving-coil 2 inwall, then be beneficial to (being rotated counterclockwise in Fig. 1) when driving disc 1 reverses, flexible rod 3 the other end and limit dais 21 smoothly intermittence are slidably matched; Block face 212 is crossing with from moving-coil 2 inwall is at right angles acute angle, be then beneficial to (turning clockwise in Fig. 2) when driving disc 1 rotates forward, and flexible rod 3 the other end is stably kept out with block face 212 and can not slippage, to transmit larger torque.
For making the telescopic slide of flexible rod 3 more stable and can obtaining spacing, have the chute 11 for flexible rod 3 telescopic slide in driving disc 1, flexible rod 3 is positioned at chute 11.
As one preferred embodiment, this example realizes flexible rod 3 and with the elastic connection way of driving disc 1 is: one end of flexible rod 3 is connected with spring 4, and spring 4 is affixed with driving disc 1.
More specifically, the spring 4 of this example is the torsion spring crossing with flexible rod 3, and driving disc 1 has the fan groove 12 swung for torsion spring, one end of torsion spring is fixed in fan groove 12 one end, and the other end of torsion spring is positioned at fan groove 12 the other end and is slidably matched with flexible rod 3.Torsion spring provides an outwardly directed elastic force for flexible rod 3, and the mode of the elastic force adopting torsion spring to provide is beneficial to and provides enough elastic force, and can life-saving.
For more reliably transmitting larger torque, flexible rod 3 is more than two, and the central axis around driving disc 1 is uniformly distributed.The setting of more flexible rod 3, rotates less angle by making driving disc 1 and flexible rod 3 the other end just can be made to keep out with block face 212 coordinate.
For convenience of external transferring power; as shown in Figure 3; a gear 5 is fixed with from one of them end face of moving-coil 2; this gear 5 is with coaxial from moving-coil 2; this gear 5 is convenient to engage with transmitting torque with outer gear 5 component; be covered with a cover plate 6 from another end face of moving-coil 2, cover plate 6 is for providing protective action.
To one skilled in the art, according to technological scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
