Abstract
Provided is a pull rope fixator of a curtain. A pull rope fixing hole is mainly formed in a top surface, the pull rope fixing hole is provided with a big hole portion and at least two small hole portions, and the big hole portion and the small hole portions are connected together through two opposite clamping portions. The pore diameter of the big hole portion is bigger than the external diameter of a pull rope, the power diameter of each small hole portion is actually equal to the external diameter of the pull rope, and the distance between the two clamping portions is smaller than the external diameter of the pull rope. Therefore, the pull rope is usually arranged in the small hole portions of the pull rope fixing hole in a penetrating mode and is clamped by the two clamping portions. When the pull rope is wound, and force born by the pull rope is larger than the clamping force of the two clamping portions, the pull rope can move to the big hole portion of the pull rope fixing hole, and the pull rope fixator and the pull rope are enabled to instantly form a separating state to increase using safety.

The specific embodiment
Stay cord fixator of the present invention is a housing, the end face of this housing has a stay cord fixing hole, this stay cord fixing hole has a macropore section and at least two aperture sections, be engaged togather via two relative holding sections between this macropore section and this aperture respectively section, wherein, the aperture of this macropore section is greater than the external diameter of this stay cord, can pass through for this stay cord, respectively the aperture of this aperture section equals in fact the external diameter of this stay cord, use for this stay cord and place, the spacing of this two holding section is less than the external diameter of this stay cord, in order to block this stay cord.
In order to describe structure of the present invention, feature and effect place in detail, hereby enumerate two preferred embodiments and coordinate lower description of drawings such as rear.
see also Fig. 1, the stay cord fixator 10 that provides for the present invention's the first preferred embodiment, made housing is formed in one, the end face of housing has a stay cord fixing hole 12, stay cord fixing hole 12 has a macropore section 122 and three aperture sections 124, be engaged togather via two relative holding sections 126 between macropore section 122 and each aperture section 124, as Fig. 2 and shown in Figure 4, the aperture of macropore section 122 can be passed through for stay cord 20 greater than the external diameter of stay cord 20, the aperture of each aperture section 124 equals in fact the external diameter of stay cord 20, use for stay cord 20 and place, the spacing of this two holding section 126 is less than the external diameter of stay cord 20, in order to block stay cord 20.
when usually using, stay cord 20 is be placed through in the aperture section 124 of stay cord fixing hole 12 and blocked by this two holding section 126, as shown in Figure 2, when having foreign matter (as child's neck) to enter between stay cord 20 and pressing down, the stay cord 20 of this moment can present the state of cross winding, as shown in Figure 3, in case stay cord 20 is in suffered strength during greater than the engaging power of this two holding section 126 of stay cord fixing hole 12, stay cord 20 can move to from the aperture section 124 of stay cord fixing hole 12 the macropore section 122 of stay cord fixing hole 12, as shown in Figure 4, the stay cord 20 of this moment can form released states with stay cord fixator 10 of the present invention via the macropore section 122 of stay cord fixing hole 12, as shown in Figure 5, so can effectively avoid producing the danger of strangulation, to reach the purpose that increases safety in utilization.
Please consult again Fig. 8, stay cord fixator 30 for the present invention's the second preferred embodiment, be that with the Main Differences of above-described embodiment housing has one first side cover 40 and one second side cover 50, stay cord fixing hole 32 is formed between the end face of the end face of the first side cover 40 and the second side cover 50.
As shown in Figure 9, the first side cover 40 caves in from inner wall surface thereof and a caulking groove 42, and to have 46, the first junction surfaces 46, one first junction surface be two shrinkage pools of space at the present embodiment in the bottom surface that stretches out clamping wall 44, the first side covers 40 in the position of adjacent caulking groove 42.
as Fig. 9 and shown in Figure 10, the second side cover 50 stretches out a wall embeded 52 from inner wall surface thereof, wall embeded 52 has a packing end 522, packing end 522 protrudes from the inner peripheral of the second side cover 50, in order in the caulking groove 42 that is embedded at the first side cover 40 and with the mutual packing of clamping wall 44 of the first side cover 40, packing end 522 has a breach 524, convenience when assembling in order to provide the strain effect to increase, in addition, the bottom surface of the second side cover 50 stretches out a joined wall 54, joined wall 54 has one second junction surface 56, the second junction surface 56 is two salient points of space at the present embodiment, in the first junction surface 46 (shrinkage pool) that is sticked in the first side cover 40.
thus, when having foreign matter (as child's neck) to enter between stay cord 20 and pressing down, stay cord 20 can present the state of cross winding, as shown in figure 12, in case stay cord 20 is in suffered strength during greater than the engaging power of this two holding section 326 of stay cord fixing hole 32, stay cord 20 can move to from the aperture section 324 of stay cord fixing hole 32 the macropore section 322 of stay cord fixing hole 32, as Figure 11 and shown in Figure 13, at this moment, stay cord 20 may be one by one directly breaks away from stay cord fixator 30 of the present invention via macropore section 322, as shown in figure 14, what produce in the time of perhaps may being stuck in macropore section 322 because of all stay cords 20 pushes strength greater than the frictional force between the wall embeded 52 of the clamping wall 44 of the first side cover 40 and the second side cover 50, force the clamping wall 44 of the first side cover 40 and the wall embeded 52 of the second side cover 50 to be separated from each other, the first side cover 40 and the second side cover 50 will outwards peel off moment and with stay cord 20 between can separate fully, as shown in figure 15, no matter yet be above-mentioned which kind of situation, all can effectively avoid producing the danger of strangulation, to reach the purpose that increases safety in utilization.
What need in addition to be worth mentioning is, the number of stay cord fixing hole 12,32 aperture section 124,324 is not limited to three, also can be two or four, as long as coordinate the number of stay cord 20, as Fig. 6, Fig. 7, Figure 16 and shown in Figure 17.
