Specific embodiment
Cooperate schema, the technology contents and spy that the present invention will be described in detail by cited several preferred embodiments below
It levies, "top" mentioned by the content of the present specification, "bottom", "left", "right", "inner", "outside" isotropy describe term, only with just
It is often used the illustration on the basis of direction and describes term, be not construed as limiting the purpose for advocating range.
Please referring to Fig. 1 to 2, separate type blade angle adjusting mechanism 10 of the invention includes a shell 20, a worm gear 30,
And one turn component 40.
Shell 20 is mutually butted by two half shells 22, and shell 20 forms a level between two half shells 22
The first mounting groove 24 and one through left and right two relative side is oblique through top, the second mounting groove 26 of bottom two relative side.
Worm gear 30 is rotatably arranged in the first mounting groove 24 of shell 20 and has a rectangle blocked hole 32, rectangle clamping
Hole 32, which is used to wear for a shaft 12, to be connect, and shaft 12 is enable to rotate synchronously with worm gear 30.
Component 40 is turned to turn bar 50 and one second with one first and turn bar 60, in which:
First, which turns bar 50, is rotatably arranged in the second mounting groove 26 of shell 20 and has a worm screw portion 51 and a card
Socket part 52, in worm gear 30, clamping portion 52 is integrally connected worm screw portion 51 and has an axis hole 53, two opposite 51 bridle joint of worm screw portion
Location hole 54 and a circular engagement slot 55, in which: axis hole 53 prolongs from the bottom face of clamping portion 52 along towards the direction in worm screw portion 51
It stretches, moreover, the axial direction for being axially parallel to worm screw portion 51 of axis hole 53；The axial direction for being axially perpendicular to axis hole 53 of location hole 54, it is fixed
The one end in position hole 54 is connected to the top of axis hole 53, and outer peripheral surface of the one end of location hole 54 in clamping portion 52 forms an opening；It connects
Slot 55 is closed to be adjacent to the bottom end of axis hole 53 and be interconnected with axis hole 53.
Second turns the second mounting groove 26 that bar 60 is rotatably arranged in shell 20, and the second top for turning bar 60 is located at shell
In body 20 and there is an axle portion 61, two opposite positioning convex portions 62 and a circular engagement portion 63, in which: axle portion 61 has a notch
64, the ability for making axle portion 61 that there is flexible deformation by notch 64, with ease of assembly；Positioning convex portion 62 is from the top of axle portion 61
Outer peripheral surface along axle portion 61 radial integrated extend outward；Circular engagement portion 63 is adjacent to the bottom end of axle portion 61.In addition, second
The bottom end for turning bar 60 is located at outside shell 20 and has one to hook card hole 65, is blocked with so that a transfer rod 14 hooks.
When first, second turns bar 50,60 and assembled, second, which turns bar 60, is arranged in first by axle portion 61 and turns
In the axis hole 53 of bar 50, while it being connected in by two positioning convex portions 62 location hole 54 for the clamping portion 52 that first turns bar 50 respectively
It is interior, to ensure that the two can not be detached from after assembly is completed, the second hook card hole for turning bar 60 is stuck in using the hook of transfer rod 14 at this time
In 63 and force rotates transfer rod 14, so that transfer rod 14 is turned bar 60 by second and drives worm gear 30, worm gear 30 is after turning
Achieve the effect that adjust blade angle by shaft 12 and other transmission components.
In order to further ensure that first, second turns and cannot rotate relative to each other after assembly is completed between bar 50,60, such as scheme
Shown in 3 to 5, first turn the axis hole 53 of bar 50 and second turn bar 60 axle portion 61 all have non-circular section configuration,
In the present embodiment, the section configuration of axis hole 53 and the section configuration of axle portion 61 are hexagon, but are not limited with this shape,
It can be presented with the kenel of other polygons.
It can be seen from the above, worm gear 30 and first turns 50 script of bar and is just hidden in shell 20, bar 60 is turned as second
It is individual independently separated component, consumer is allowed to drive in a manner of voluntarily assembling by second after buying relevant window covering products
Bull stick 60 is fixed on first and turns bar 50.In other words, it second turns bar 60 and can't be protruded out in the process packed and transported
Out outside shell 20 and upper beam, so not only bar 60 can be turned to avoid second and be broken by improper external force, while can also
The extruding of bar 60 is turned by second to avoid blade and is damaged or is deformed.
