Still referring to fig. 3, since the operation mechanism of the present embodiment is in a single operation mode, the single operation mode refers to that only one inner operating device 6 and one outer operating device 7 operate the blind lifting traction rope 70 and the blind turning traction rope 80, that is, the blind 5 is lifted and the blind 53 is turned. Since the inner operating mechanism 6 is disposed on the right side and is vertically slidably fitted in the right vertical frame groove 431 in this embodiment, an outer operating mechanism guide slide 401 is fixedly disposed on the front side of the front glass 40, i.e., the side facing away from the rear glass 50, and the outer operating mechanism 7 is slidably fitted in the outer operating mechanism guide slide 401 and magnetically attracted to the inner operating mechanism 6 via the front glass 40. In the present embodiment, the inner operating mechanism 6 is disposed in the right vertical frame strip groove 431 of the right vertical frame strip 43, the curtain turning traction rope tensioning device 9 is disposed at the lower portion of the right vertical frame strip groove 431, and the traction rope transition guide seat 1 and the synchronous curtain turning shaft actuating device 2 are disposed at the upper right corner of the window 3, so that the left vertical frame strip groove 421 does not play a substantial role, and the frame strip groove sealing plate 4211 is used to seal the left vertical frame strip groove 421 to enhance the viewing effect. The pair of turning drums 8 are disposed in the upper horizontal frame bar slot 411 through the turning drum seats 81, the turning drum support shaft heads at the two ends of the turning drum 8 are rotatably supported on the turning drum seats 81, and the turning drum seats 81 are fixed with the bottom plate of the upper horizontal frame bar slot 411.

The applicant needs to state that: if the inner control mechanism 6, the curtain sheet overturning and traction rope tensioning device 9, the traction rope transition guide seat 1 and the synchronous curtain sheet overturning shaft actuating device 2 are transferred to the left side of the window body 3, and the outer control mechanism 7 is the same as the inner control mechanism, the left longitudinal frame groove 421 is started, and the frame groove sealing plate 4211 is transferred to the right side and covers the right longitudinal frame groove 431; if a double-control structure is adopted, the turning wheel 30, the curtain turning traction rope 80 and the internal and external control mechanism for controlling the curtain turning traction rope are arranged on the left side of the window 3, in this state, the left longitudinal frame groove 421 is started, and the internal and external control mechanism for controlling the blind lifting traction rope is arranged on the right side of the window 3, in this state, the right longitudinal frame groove 431 is started. This case has two inner and

outer operating mechanisms

6, 7. Based on the foregoing explanation, can not limit the technical connotation of the technical solution disclosed by the utility model with the position change of unilateral control and the structural style of adopting two controls.

Referring to fig. 4, in fig. 4, there is shown the curtain turning traction rope tensioning device 9 schematically shown in fig. 1 and mentioned above many times, the curtain turning traction rope tensioning device 9 includes a spring seat 91, a spring 92, a tension roller seat 93 and a curtain turning traction rope tensioning roller 94, the spring seat 91 is disposed at the lower portion of the right vertical frame strip groove 431 of the right vertical frame strip 43 and fixed with the right vertical frame tube 34 by a fixed pin shaft (not shown), a spring shaft 911 is formed in a longitudinally cantilevered state at a side of the spring seat 91 facing the tension roller seat 93, a spring shaft seat stop lever 912 is disposed at the lower portion of the spring seat 91, the spring 92 is sleeved on the spring shaft, a side of the tension roller seat 93 facing the spring seat 91, i.e. a right side shown in fig. 3, is formed with a spring shaft seat 931, the spring shaft seat 931 is supported on the spring stop lever 912, the lower end of the spring shaft 911 is inserted into the spring shaft seat cavity 9311 of the spring shaft seat 931, the upper end of the spring 92 is supported on the top wall of the spring seat 91, the lower end is supported on the shaft seat upper end face 9312 of the spring shaft seat 931, the curtain turning traction rope tension pulley 94 is rotatably disposed in the tension pulley seat cavity 932 of the tension pulley seat 93 through a tension pulley shaft 941, and the middle portion of the curtain turning traction rope 80 is sleeved on the curtain turning traction rope tension pulley 94.

When the blind 5 is to be raised, the user moves the outer operating mechanism 7 (also called "outer operator") downward, i.e. the outer operating mechanism 7 moves downward along the guiding slot of the guiding slide bar 401 of the outer operating mechanism, because the outer operating mechanism 7 is magnetically attracted to the inner operating mechanism 6 through the front glass 40, the inner operating mechanism 6 is correspondingly moved downward when the outer operating mechanism 7 moves downward, because the blind lifting traction rope 70 is sleeved on the inner operating mechanism connecting rope pulley 61, and because the inner operating mechanism connecting rope pulley 61 drives the blind lifting traction rope 70 to take up the blind lifting traction rope 70 when the inner operating mechanism 6 moves downward, because one end of the blind lifting traction rope 70 is fixed to the blind bottom bar 52 of the blind 5, and the other end is fixed to the blind lifting traction rope fastening hole 1311 and the blind lifting traction rope fastening hole 1421, thus causing the blind 5 to rise upwards in the aforesaid retracted condition and vice versa, not to be repeated.

When the slats 53 of the blind 5 are to be tilted by a certain angle, the inner operating mechanism 7 is also displaced correspondingly by the user through the operation of the outer operating mechanism 6, thereby driving the curtain turning traction rope 80 with the two end parts fixed with the curtain turning traction rope 80, driving the turning wheel 30 by the curtain turning traction rope 80, because the torsion spring 23 of the structural system of the synchronous curtain sheet turnover shaft actuating device 2 is tightly sleeved at the left end of the turnover wheel shaft 301 of the turnover wheel 30, and because the right end of the torsion spring actuating plate shaft 21 is rotatably inserted into the actuating plate shaft inserting hole 3011 of the turnover wheel shaft 301, and because the torsion spring actuating plate 22 corresponds to the position between the first torsion spring leg I231 and the second torsion spring leg II 232 of the torsion spring 23, therefore, when the turning wheel 30 is driven by the curtain turning traction rope 80, the turning wheel 30 drives the turning wheel shaft 301, and the turning wheel shaft 301 drives the torsion spring 23 to correspondingly rotate for a certain angle along with the turning wheel shaft. In the above process, when the first torsion spring leg 231 is in contact with the front side of the torsion spring actuating plate 22 and then rotates along with the turning axle 301, the first torsion spring leg i 231 drives the torsion spring actuating plate 22 and the torsion spring actuating plate 22 drives the torsion spring actuating plate shaft 21 to rotate by a certain angle, because the right end of the curtain sheet turning shaft 20 is inserted into the turning shaft insertion hole 211 at the left end of the torsion spring actuating plate shaft 21, the curtain sheet turning shaft 20 is driven to rotate by a certain angle in the process of rotating by a certain angle, that is, the same angle, the curtain sheet turning shaft 20 drives the turning drum 8 inserted and fixed therewith, the turning drum 8 drives the curtain sheet ladder cords 51 of the blind 5, and the curtain sheets 53 arranged on the curtain in the spaced state are turned by a certain angle by the curtain sheet ladder cords 51. In the foregoing process, if the turning rope 80 is continuously dragged to turn the curtain sheet after the turning rope is turned to the limit, the second torsion spring leg ii 232 is in the blocking state by the torsion spring leg baffle 17 on the traction rope transition guide seat 1, the torsion spring 23 will be loosened, i.e. no longer tightly clasped with the turning wheel shaft 301, so that the first torsion spring leg i 231 will not continuously drive the torsion spring actuating plate 22 to rotate, the torsion spring actuating plate shaft 21 is also in the stationary state, and the turning wheel 30 is in the idle state because the turning wheel shaft 301 is not clasped by the torsion spring 23 (the clasping of the torsion spring 23 to the turning wheel shaft 301 is temporarily abandoned). Since the curtain sheet 53 is turned in the direction opposite to the above direction, it is only necessary to operate the external control mechanism 6 in the direction opposite to the above direction, and thus the description thereof is omitted.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
