The specific embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 5-7, a kind of window curtain lockset, its lockset shell 1 has inner chamber 2, the top of lockset shell 1 has and is used for fixing the Connection Block 3 that lockset is installed, lockset shell 1 around have four sidewalls, be connected with axostylus axostyle 4 between two sidewalls that are oppositely arranged, this axostylus axostyle 4 can adopt parts well-known to those skilled in the art such as rivet, one of them inside surface of side wall is processed into the flank of tooth 5 on two other sidewall, the tooth of the flank of tooth 5 is arranged continuously along above-below direction, be with transmitting gear 6 on the rivet axostylus axostyle 4, the turning cylinder that this axostylus axostyle 4 is connected with transmitting gear 6 as lockset shell 1.In the inner chamber 2 of lockset shell 1 free gear 7 is arranged, transmitting gear 6 parallels with the center line of free gear 7, and transmitting gear 6 setting that is meshed with the tooth of free gear 7, the setting that is meshed with the tooth of the flank of tooth 5 of the tooth of free gear 7, therefore free gear 7 can be on the flank of tooth 5 scroll-up/down, between the flank of tooth 5 and the transmitting gear 6 suitable spatial accommodation is arranged, this spatial accommodation is used to receive free gear 7.Carriage 8 is arranged at the bottom of lockset shell 1, this carriage 8 is used for support free gear 7, between lockset shell 1 upper top and the sidewall opening 9 is arranged, this opening 9 is connected with inner chamber 2, stay cord 10 enters inner chamber 2 from opening 9, passes the gap between free gear 7 and the transmitting gear 6, passes from the bottom of lockset shell 1, the end that passes is for people's hand operation, and the other end of stay cord 10 is connected with weight.Free gear 7 has two states-clamped condition and releasing orientation, and when free gear 7 was in clamped condition, free gear 7 was stuck between the transmitting gear 6 and the flank of tooth 5; When free gear 7 was in releasing orientation, this free gear 7 was separated with transmitting gear 6, and the conversion between free gear 7 two states realizes by operation stay cord 10.Spur stay cord 10 downwards, curtain is drawn in, stay cord 10 drives free gear 7 and scrolls up along the flank of tooth 5, when free gear 7 has been rolled into just and the flank of tooth 5 and transmitting gear 6 are in contact, because forming the sidewall of the flank of tooth 5 is to be made by working of plastics, has higher elastic deformation ability, deformation can take place in the flank of tooth 5 or the sidewall that has a flank of tooth 5, cause gear 7 under effect of inertia, to continue to scroll up, in the tooth of gear 7 is stuck in the teeth groove of the teeth groove of the flank of tooth 5 and transmitting gear 6, engagement by tooth, free gear 7 can stably be stuck between the flank of tooth 5 and the transmitting gear 6, this moment, stay cord 10 was clamped between free gear 7 and the transmitting gear 6, the fixed-site of stay cord 10, then curtain also is in stable rounding state, and the sidewall that has the flank of tooth 5 on the lockset shell 1 is provided with reinforcement 11, this reinforcement 11 can reinforced sidewall be subjected to force intensity, what prevent that the regular elastic deformation in sidewall position from causing splits.In the present embodiment, reinforcement 11 is located on the external surface of sidewall, and the position that is used to block free gear 7 on the sidewall on the position of reinforcement 11 and the flank of tooth 5 is corresponding, and specifically, reinforcement 11 is for being located at the reinforcing rib on opening 9 limits, as Fig. 5 or shown in Figure 7.Be used to block position stressed maximum when chucking free gear 7 of free gear 7 on the flank of tooth, therefore this position is the easiest splits, directly on the external surface of this position corresponding side walls, be provided with reinforcement 11, can stop the impaired of the position that is used to block free gear 7 on the flank of tooth effectively or split, and can not influence cooperating of free gear 7 and the flank of tooth 5, the lockset that has this reinforcement can extend application life.Give stay cord 10 1 active forces again, the teeth groove of the tooth of gear 7 and the flank of tooth 5, transmitting gear 6 is separated, then free gear 7 falls under the effect of gravity, drops down onto on the carriage 8 of lockset shell 1 bottom.Then stay cord is released, and this action of gravity in weight of curtain launches down.
Further, the wall thickness that has the inside wall of the flank of tooth 5 on the lockset shell 1 is 3.3～3.5mm, the wall thickness of prior art is generally 2.6mm, because free gear 7 rolls on the flank of tooth 5 of the sidewall of being everlasting, then the flank of tooth 5 is easy to wear, with the intensity of this sidewall thickening can enhancing sidewall, increase the service life in the utility model.
Also have, when free gear 7 stably is stuck between the flank of tooth 5 and the transmitting gear 6, except the flank of tooth 5 is stressed easily split, the axostylus axostyle 4 of transmitting gear 6 is also easily stressed and by stretch bending, the diameter of rivet axostylus axostyle 4 is 5.4～5.6mm on the lockset shell 1, the diameter of this axostylus axostyle 4 is used to strengthen stress-bearing capability with respect to the prior art overstriking.
