The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Referring to Fig. 1, curtain pulling bead 4 is serially connected with in the end to end backguy by many beads and forms, and leaves certain spacing between the bead.The top of bead 4 is positioned curtain brake A, and with its interlock; The bottom is positioned curtain pulling bead fixing apparatus B, and with its interlock.
Referring to Fig. 2-16, the present embodiment curtain pulling bead fixing apparatus B comprises holder 2, bottom 3, pearl dish 11, button 5, control spring 6, main body 7, slide block 10, protecgulum 12, holder 2 is rectangular-shaped, it is fixedly installed in wall or window frame by two self-tapping screws 1, and medial surface and wall or window frame are affixed.
The lateral surface 2-1 of holder 2 forms the vertical teeth 2-2 of two rows, and the top of each teeth is the inclined-plane in (outside) up, and the bottom is down a plane.Two longitudinal edges of this lateral surface 2-1 are along respectively continuously forming the vertical chute 2-3 of twice behind twice 90 degree of turnover, and the vertical chute 2-3 of twice is towards relatively.
The rectangular trapezoidal shape in longitudinal section of the elastic clamping block 3-5 of bottom, its plane is in top, and the inclined-plane is under bottom and the court (outward).Fixture block 3-5 and the teeth 2-2 on the holder 2 of bottom 3 are suitable, and namely fixture block 3-5 blocks mutually with the teeth 2-2 of holder 2, and bottom 3 can only down sliding, but can not upward sliding, thereby can adjust the degree of tautness of bead.
The middle part of bottom 3 forms a through hole 3-3, and through hole 3-3 is vertical ellipticity, and a protruding 3-4 who makes progress is formed on its bottom.Button 5 is passed at the through hole 3-3 place of bottom 3; The body of button 5 is cylindric, and the width of the external diameter of this cylindrical body and elliptical hole 3-3 is suitable, but less than the height of elliptical hole 3-3, thereby bottom 3 can be made upper and lower translation along button 5.The inner 5-4 of button 5 passes the lateral surface 2-1 that peaks at holder 2 behind the through hole 3-3 of bottom 3.The bottom of button body (near inner 5-4) has draw-in groove 5-2, and draw-in groove 5-2 offers along the length direction of button 5, and the protruding 3-4 of this draw-in groove 5-2 and bottom 3 is suitable, and namely chute 5-2 inserts the protruding 3-4 of bottom 3 and blocks mutually.
The other end of button 5 is end cap, and its external diameter is a bit larger tham the button body, near the outer wall formation external tooth 5-1 of this end.Button 5 has interior cylindrical hole 5-3 along its length direction, and this cylindrical hole 5-3(is by the end cap place) connect with extraneous.Insert control spring 6 in this cylindrical hole 5-3.
The lower end of curtain pulling bead 4 is positioned pearl dish 11, and the structure of pearl dish 11 is as follows: pearl dish 11 has through hole 11-1, and the inwall of this through hole forms internal tooth 11-2.Pearl dish through hole 11-1 passes the body of button 5 and is not with toothed portion, thereby can rotate.The outer ring of pearl dish 11 forms both sides retaining wall 11-3, and both sides retaining wall 11-3 is uniform along two edges, outer ring of pearl dish 11 respectively, and both sides retaining wall 11-3 is spaced.Have circular hole 11-3-1 on the retaining wall 11-3, the bead of this circular hole and bead 4 is suitable; The spacing of the spacing of the circular hole 11-3-1 that heteropleural is adjacent and bead 4 adjacent beads is suitable.Form arc-shaped depression portion 11-4 on the pearl dish outer ring corresponding with each retaining wall 11-3 (circular hole), the bead of this arc-shaped depression portion and bead 4 is suitable, by the circular hole 11-3-1 positioning action on this arc-shaped depression portion and the retaining wall, with the bead location of bead 4.
The outside assembling main body 7 of bottom 3.The lateral surface of bottom 3 forms two reference column 3-2, and the edge of this side forms three grab 3-1, and is corresponding, and main body 7 forms two locating hole 7-5, and three button hole 7-1.Bottom reference column 3-2 stretches into the locating hole 7-5 of main body, and is assembled together with making bottom 3 and main body 7 cooperating of button hole 7-1 by grab 3-1.Pearl dish 11 is between bottom 3 and the main body 7, and certainly, the upper wall of main body 7 has two passes, and two passages extend to main body 7 inside, for stretching through of bead 4.
Main body 7 has a square hole 7-4, and this square hole is inserted the slide block 10 that an outer is square, and both width are suitable, but the height of square hole 7-4 is greater than the height of slide block 10, thereby can make main body 7 make upper and lower translation with respect to slide block 10.Have a hole 7-3 on the main body 7, this hole extends to the upper wall of square hole 7-4 from top to down, packs in this hole and regulates stage clip 9, and the upper end of regulating stage clip 9 peaks to screw in marks closely screw 8 in the hole, and the lower end peaks at the upper wall of slide block 10.
The lateral surface assembling protecgulum 12 of main body 7.The lateral surface of main body 12 forms three button hole 7-2, and is corresponding, and protecgulum 12 forms three grab 12-1, and the clamping by grab 12-1 and button hole 7-2 is assembled together protecgulum 12 and main body 7.
The inner of control spring 6 peaks at the hole inwall of button 5, and the outer end then peaks at the inwall of protecgulum 12.
Those of ordinary skill in the art will be appreciated that; above embodiment illustrates the present invention; and be not as limitation of the invention, as long as within the scope of the invention, all will drop on protection scope of the present invention to variation, the distortion of above embodiment.
