It will no doubt be determined by a reading of the patent literature that is not limited to the above list and in combination with general knowledge: the blind arranged in the double-layer hollow glass must meet the requirements of lifting according to requirements and turning over the blind sheet. The process of the curtain piece overturning is as follows: because the outer manipulator, namely the outer control mechanism, is magnetically attracted with the inner manipulator, namely the inner control mechanism, which is positioned between the front glass (the glass facing the indoor in the use state) and is in sliding fit with the longitudinal frame cavity of the longitudinal frame strip of the inner frame body, when a user stirs the outer manipulator, the outer manipulator drives the inner manipulator, the inner manipulator drives the curtain sheet overturning traction rope, the curtain sheet overturning traction rope drives the overturning wheel, the overturning wheel drives the curtain sheet overturning shaft fixedly inserted with the curtain sheet overturning shaft, the curtain sheet overturning shaft drives the overturning roller (also called overturning drum) fixedly inserted with the curtain sheet overturning shaft and two ends of which are rotatably supported on the overturning roller seat (also called overturning drum seat), because the overturning roller seat and the overturning roller are arranged on the upper transverse frame strip of the inner frame body, and because the upper end of the ladder rope of the shutter curtain is fixed with the overturning roller, when the curtain sheet overturning shaft rotates clockwise or anticlockwise by a required angle, the turning roller (i.e., the turning drum) is driven by the turning roller to correspondingly rotate by a required angle, so that the curtain sheet is turned inwards or outwards by the required angle through the ladder rope by the turning roller.
According to the above description, only if the turnover rope stably drives the curtain piece turnover shaft through the turnover wheel, the stable turnover effect of the ladder rope on the curtain piece can be ensured. In the prior art, the connection mode of the curtain sheet turning shaft and the turning wheel can be disclosed by CN108825101A (single-side control double-layer hollow glass built-in blind window) and CN208885163U (double-control warm-frame hollow glass blind window), because the turning wheel is positioned at one side of a corner seat or a traction rope transition guide device facing to a longitudinal frame strip of an inner frame body, the curtain sheet turning shaft can only pass through the corner seat or the traction rope transition guide device called by CN108825101A and then is fixedly inserted with the turning wheel shaft of the turning wheel, so that one end of the curtain sheet turning shaft fixed with the turning wheel and the turning wheel are in an unsupported cantilever or suspended state (see CN2 in detail), the abnormal vibration situation can inevitably occur in the action process of turning the curtain sheet traction rope, the vibration of the turning wheel and the turning shaft can seriously affect the overall rotation stability of the curtain sheet turning shaft, and the rotation of the turning roller, namely the turning drum can not be synchronous with the curtain sheet turning shaft in serious cases, finally, the effect that the curtain sheet is driven by the ladder rope to turn is influenced. In addition, since the limiting flange is formed on the turning roller, i.e. the turning drum, the limiting flange and the limiting foot are matched to play a role in limiting the limit degree of clockwise or counterclockwise rotation of the turning drum (see paragraph 0043 of the specification of CN20885163U in particular). The structural design that the turnover roller stops by the limiting flange so as to stop the turnover shaft of the curtain sheet and the turnover wheel is also in a stop state is theoretically and technically free from technical problems in consideration of the conventional technology, and once the limiting flange is blocked by the limiting foot, the turnover rope, namely the turnover traction rope of the curtain sheet cannot drive the turnover wheel, but the following two undesirable defects can be exposed in the actual use process: firstly, the limit flange formed on the turnover drum is impacted at the moment of contacting with the limit foot, which is very unfavorable corresponding to the stable movement of the ladder rope driven by the turnover drum, and the limit flange is damaged by collision; it is two, even make the upset drum be in can not then pivoted state at limit flange, if continue to drag the curtain piece upset haulage rope, then also be in quiescent condition because of the trip wheel, then can appear damaging and even cracked condition when dragging the curtain piece upset haulage rope then to the race of trip wheel also can suffer contusion of different degrees promptly the grooving.

One window frame tube corner connecting piece 10 positioned at the upper left corner in the other three window frame tube corner connecting pieces 10 is connected with the left end of the upper transverse frame tube 31 and the upper end of the left longitudinal frame tube 33 in an inserting and embedding manner, one window frame tube corner connecting piece 10 positioned at the lower left corner is connected between the lower end of the left longitudinal frame tube 33 and the left end of the lower transverse frame tube 32 in an inserting and embedding manner, and one window frame tube corner connecting piece 10 positioned at the lower right corner is connected between the lower end of the right longitudinal frame tube 34 and the right end of the lower transverse frame tube 32 in an inserting and embedding manner.
As shown in fig. 2, an upper horizontal frame groove 411 is formed in the longitudinal direction of the upper horizontal frame 41 of the structural system of the inner frame 4 and on the side facing the front glass 40, a left vertical frame groove 421 is formed in the height direction of the left vertical frame 42 and on the side facing the front glass 40, and a right vertical frame groove 431 is formed in the height direction of the right vertical frame 43 and on the side facing the front glass 40.
Still referring to fig. 2, 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 control 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 turning wheel shaft linkage and release mechanism 2 are disposed at the upper right corner of the window 3, so that the left vertical frame strip groove 421 is not substantially acted, and the frame strip groove sealing plate 4211 is used to seal the left vertical frame strip groove 421, thereby enhancing 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 traction rope tensioning device 9, the traction rope transition guide seat 1 and the overturning wheel shaft linkage and release mechanism 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 strip groove 421 is started, and the frame strip groove sealing plate 4211 is transferred to the right side and shields the right longitudinal frame strip 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. In addition, since the curtain turning and pulling rope tensioning device 9 belongs to the prior art, for example, refer to the patent documents mentioned in the above background art column by the applicant, and thus, the description thereof is omitted.
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 retract 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 end hanging flange 17 of the blind lifting traction rope, the blind 5 is raised upward under the state of the retraction rope, vice versa and will not 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 turning wheel shaft linkage and release mechanism 2 is tightly sleeved at the left end of the turning wheel shaft 301 of the turning wheel 30, and because the right end of the torsion spring actuating plate shaft 21 is rotatably inserted into the actuating plate shaft insertion hole 3011 of the turning 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 curtain 53 has been overturned to the limit, and then the curtain turning traction rope 80 is continuously pulled, the torsion spring 23 will be loosened because the second torsion spring leg ii 232 is in the blocking state of the torsion spring leg baffle 16 on the traction rope transition guide seat 1, i.e. the torsion spring 23 is no longer tightly clasped with the overturning wheel shaft 301, so that the torsion spring actuating plate 22 will not be continuously driven to rotate by the first torsion spring leg i 231, the torsion spring actuating plate shaft 21 is also in the stationary state, and the overturning wheel 30 is in the idle state because the overturning wheel shaft 301 is not clasped by the torsion spring 23 (the clasping of the torsion spring 23 to the overturning 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.
