Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing:
As shown in Figure 1, driving mechanism of the present invention include lever 1, telescopic rod 2, ratchet 3, pawl 4, first gear 5,
Second gear 6, cam 7, swing rod 8, spring 9, connecting rod 10 and return spring 11.
1 inner hollow of lever, 2 one end of telescopic rod pass through inside lever 1, stretch out from 1 other end of lever, 1 other end of lever
It is hinged fixed, and lever 1 can be rotated upwardly and downwardly around articulated shaft；The upper side and lower side of lever 1 is provided with limiting device, for making
The rotational angle of lever 1 is fixed, and 1 side of lever is provided with return spring 11, after pushing lever 1, gives lever 1 one
Upward power, being capable of self-return after pushing lever 1；Or return spring 11 is only provided on the downside of lever 1, lever 1 is pressed
The extreme position and return spring 11 of contracting return spring 11 under natural conditions when lever 1 position, between the two positions, i.e.,
For the rotational angle of lever 1, return spring 11 not only push lever 1 after can self-return, also instead of limiting device
Function.
The positional relationship of ratchet 3 and articulated shaft be it is coaxial, 4 one end of pawl and lever 1 are hinged, 4 other end of pawl and ratchet 3
Connection, is provided with extension spring 9 on the lever 1 of the top of pawl 4, the pulling force upward to pawl 4 of extension spring 9, when pawl 4 with hold
When handle 1 is parallel, extension spring 9 is nature；Such design is not directly contacted with ratchet 3 and lever 1, and ratchet 3 can't
It following lever 1 to rotate together, but is rotated down by lever 1, pawl 4 pushes ratchet 3 to rotate, when lever 1 is rotated up, spine
It is fixed to take turns 3.
Ratchet 3 is coaxially fixed with first gear 5, and 5 gear of first gear is connected with second gear 6, cam 7 and second gear
6 is coaxial fixed, and 5 diameter of first gear is greater than 6 diameter of second gear；Cam 7 and 8 one side contacts of swing rod, the setting of 8 other side of swing rod
It is provided with the spring 9 of thrust, it is hinged to pass through connecting rod 10 between 2 one end of 8 one end of swing rod and telescopic rod.
1 initial position of lever is the most upper place of its pivot region, and when lever 1 rotates down, pawl 4 follows lever 1 to moving down
Dynamic, pawl 4 pushes ratchet 3 to rotate, and ratchet 3 drives first gear 5 to rotate synchronously, and first gear 5 drives second gear 6 to rotate,
The rotation band moving cam 7 of second gear 6 rotates synchronously；When the short radius of cam 7 and swing rod 8 contact, spring 9 gives swing rod 8 one
Thrust, swing rod 8 drive telescopic rod 2 to stretch out；When the major radius of cam 7 and swing rod 8 contact, swing rod 8 drives telescopic rod 2 to retract.
It when lever 1 is rotated up, while pawl 4 follows lever 1 to move up, rotates down, the ratchet 3 disengaged
Tooth, after lever 1 recoils to initial position, extension spring 9 by pawl 4 be stretched to holding rod parastate, pawl 4 contact with
Corresponding 3 tooth of ratchet in the position, in this uphill process, pawl 4 can not push ratchet 3, therefore ratchet 3 is fixed, cam 7
It not can rotate, 2 position of telescopic rod remains unchanged；And lever 1 is when pushing again, and since extension spring 9 can not be compressed, spine
Pawl 4 can not be rotated up, therefore ratchet 3 and lever 1 is driven to rotate synchronously, and will not generate error.
In order to which telescopic rod 2 needed for meeting bagging step stretches out, retraction and the movement to pause, the pressing of lever 1 rebound three times,
The rotation of cam 7 is turned around.
As shown in Fig. 2, 7 circumferential surface of cam is divided into three points a, b and c according to 120 °, wherein b point is 7 longest of cam half
The corresponding point of diameter；Under original state, cam 7a point is contacted with swing rod 8, and telescopic rod 2 is in stretching state at this time, subsequent cam 7 by
A point turns to b point, and telescopic rod 2 gradually retracts in the process, and cam 7 turns to c point by b point, in the process telescopic rod 2
It gradually stretches out, last cam 7 turns to a point by c point, and telescopic rod 2 keeps stretching state in the process, so far complete for one
Operating process.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
