Description

Hollow glass built-in shutter

Technical Field

The invention belongs to the technical field of sun-shading hollow glass products, and particularly relates to a hollow glass built-in shutter.

Background

The hollow glass built-in shutter has the following advantages: the heat insulation performance is good, so that the energy conservation of the building can be embodied; excellent sound insulation performance to avoid the disturbance of external noise; the condensation and frost prevention can ensure sufficient indoor light and show expected bright effect; the required indoor lighting requirement is obtained and the privacy is protected by adjusting the deflection angle of the curtain sheet of the blind; the shutter curtain sheet (the habit is called as the 'curtain sheet' for short) is prevented from being polluted by dust, so that the excellent cleaning-free effect is embodied; the decorative board has ideal decorative property for buildings so as to improve the grade of the buildings; the high-rise building has strong impact resistance, good safety and long service life, so that the installation requirement of a high-rise building can be met, and the extremely long-term use maintenance-free requirement can be met; the operation is simple, light and labor-saving, and can be suitable for people of different ages and physical abilities, and the like.

Technical information on a hollow glass built-in louver is not disclosed in the published Chinese and foreign patent documents, such as CN2564720Y (hollow glass with built-in louver), CN2767624Y (louver in hollow glass), CN2767625Y (louver in hollow glass with improved structure), CN2756796Y (louver in hollow glass), CN2232968Y (integral door and window sash with transverse louver in double glass), CN2297952Y (magnetically driven laminated retractable curtain), CN2326718Y (fully enclosed louver), CN100535378C (louver in hollow glass with improved structure), CN102444372A (a built-in sun-shading hollow louver), CN105064896B (single-control double-layer hollow glass built-in louver), CN105041168B (energy-saving multilayer hollow glass louver with simplified structure), CN105041170B (non-magnet driven double-layer hollow glass built-in louver), CN105041172B (bead chain double-layer hollow glass built-in louver), CN109538096A (double-control hollow glass built-in louver with louver cavity balanced with external pressure), CN109538097A (blind anti-slipping device for hollow glass built-in blind), CN109441323A (single-control hollow glass built-in blind capable of preventing blind slipping down) and CN109488189A (single-control hollow glass built-in blind capable of preventing inner absorption of glass), foreign patents such as US20021897681A, 1US2004211528A, US2015159431a1, GB671685A, EP2369121a2, EP1542054a1 and W003071082A, and the like.

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 sheets. 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.

As can be seen from the above description: the stable overturning effect of the ladder rope on the curtain sheet can be ensured only if the curtain sheet overturning traction rope stably drives the curtain sheet overturning shaft through the overturning wheel; the requirement of sheathing a plurality of strands of blind lifting traction ropes in a wide window state can be met only by ensuring the reasonable areas such as the lengths of the blind lifting traction ropes wound by the blind lifting traction rope transition rollers. Usually, the position of the aforementioned venetian blind lifting/pulling rope transition roller is located at a corner seat of the window body, and the venetian blind lifting/pulling rope is sleeved or pulled on a rope pulley at the upper part of the inner manipulator after passing through the venetian blind lifting/pulling rope transition roller, which is sleeved or pulled on the corner seat, and then returns upward to the aforementioned corner seat and is fixed with a hanging flange at the end of the venetian blind lifting/pulling rope preset on the corner seat.

The prior art insulating glass built-in blinds usually form independent structures between the aforementioned corner seats and the frame strip corner connectors in the shape of a substantially L-shaped or a 7-shaped structural system of the window, typically "double-operated warm-frame insulating glass blinds" as recommended by CN28885163U, and more typically "single-side-operated double-layer insulating glass built-in blinds" as provided by CN 108825101A.

The above CN108825101A can bring out the six advantages summarized in the technical effect column of the specification, but still has the following disadvantages: firstly, because the corner seat is inserted and connected with the frame strip corner connecting piece (the patent is a frame strip right upper corner connecting piece), the structural stability of the two is relatively low, in the actual use process, for example, in the process of driving the curtain strip overturning traction rope or the blind curtain lifting traction rope to act according to the requirement, the corner seat has the worry of large stress and damage, especially when the breadth of the blind curtain is increased along with the increase of the width of the blind window, the acting force in the acting process is correspondingly increased, so that the corner seat is separated from the frame strip corner connecting piece due to the difficulty in resisting the larger acting force, and the lifting of the blind curtain and the overturning of the curtain strip can not be carried out; secondly, because the right end of the curtain sheet turnover shaft passes through the corner seat in a state of being not in contact with the corner seat and is positioned on the right side of the corner seat in a horizontal cantilever state, and because the turnover wheel driving the curtain sheet turnover shaft to rotate is fixed at the right end of the curtain sheet turnover shaft, the stress degree of the turnover wheel is very weak, as mentioned above, under the condition that the width of the blind window is increased along with the width of the blind window, the turnover wheel can be forced to move because enough friction force is generated between the curtain sheet turnover traction rope driving the turnover wheel to act and the turnover wheel, and because the turnover wheel is unstable (fixed at the right end of the curtain sheet turnover shaft without support), the curtain sheet turnover traction rope and the turnover wheel are easily damaged; thirdly, because the corner seat is required to be provided with a traction rope bend pulley (called as a traction rope bend pulley) which is actually a transition roller of the lifting traction rope of the blind curtain after being bent by the bend pulley, namely the traction rope is connected with an inner control mechanism, namely the traction rope pulley is sleeved on the upper part of an inner controller, but because the cross section of the bend pulley is I-shaped or H-shaped, the area for sleeving, namely supporting the lifting traction rope of the blind curtain is limited, thereby limiting the winding of the lifting traction of the multi-strand blind curtain to a certain extent, even though CN108825101A abandons the bend pulley with the I-shaped cross section and adopts a roller-shaped structure, because gaps exist between the end surfaces at two ends of the bend pulley of the traction rope and the corresponding two side wall bodies of the corner seat, on one hand, the friction of the lifting traction rope of the blind curtain is blocked in the gap position, on the other hand, the lifting traction rope of the blind curtain is in fear of the lifting traction rope, the former can affect the service life of the lifting traction rope of the blind, and the latter can cause that the blind cannot ascend or descend; fourthly, the corner seat and the frame strip corner connecting piece are of an assembled structure with mutual insertion holes, so that the number of moulds is increased on one hand, the assembly workload is increased on the other hand, the cost is not saved, and precious labor resources are not saved; and fifthly, the function that the turnover wheel is idle when the curtain sheet of the blind is turned in place and the rotation angle of the turnover drum reaches the limit degree so as to avoid damaging the curtain sheet turnover traction rope and the turnover wheel cannot be realized, so that the effective protection effect on the turnover drum arranged on the curtain sheet turnover shaft, the turnover wheel arranged at the right end of the curtain sheet turnover shaft and used for driving the curtain sheet turnover shaft to rotate and the curtain sheet turnover traction rope sleeved on the turnover wheel and used for driving the turnover wheel to rotate cannot be realized. In view of the foregoing, there is a need for improvement, and the technical solutions described below are made in this context.

Thereby proving the expression that the cross section shape of the curtain sheet turning shaft 10 is fixedly inserted into the turning shaft insertion fixing hole 511. The applicant needs to state that: if the cross-sectional shape of the flip axis insertion hole 511 is changed from the aforementioned semicircular shape (may also be called "D-shape") to a polygonal shape such as a hexagonal shape or to a circular shape, etc., it should be considered as the technical scope of the present disclosure.

Applicant has only made a brief explanation since a further understanding of this paragraph may refer to CN108825101A, etc. However, the applicant needs to emphasize that: although fig. 1 illustrates a single-handled configuration of an insulated glazing unit blind, a double-handled configuration of an insulated glazing unit blind can equally well derive the intended purpose from the configurations of the present invention shown in fig. 3 and 4, and in particular: the second corner connector ii 7 of the frame strip at the upper left corner in fig. 1 is integrated with the corner seat 2, the curtain turning shaft supporting mechanism 21 is transferred to the second corner connector ii 7 of the frame strip at the upper left corner, the turning wheel shaft 4, the turning wheel 41 and the turning wheel shaft linkage and releasing mechanism 5 are transferred to the left, the curtain turning traction rope tensioning device 40 is also transferred to the second corner connector ii 7 of the frame strip at the lower left corner, the curtain turning inner manipulator is additionally arranged in the left longitudinal frame strip groove of the left longitudinal frame strip 67b, the curtain turning outer manipulator magnetically attracted with the curtain turning inner manipulator through the front glass 65 is additionally arranged on the left side of the front glass 65, and the curtain turning traction rope 20 is transferred to the left side. The position of the above-mentioned shutter curtain lifting traction rope transition roller 3 is still kept in the position state shown in fig. 3, so that a double-control structure like a CN208085163U is formed.

Referring to fig. 5, in fig. 5, which shows the detailed structure of the above-mentioned inner operating device 68a disposed in the right vertical frame groove 67d, the above-mentioned rope guiding pulley 68c is rotatably disposed above the inner operating device 68a via a rope guiding pulley pin 68e, the above-mentioned blind lifting/lowering traction rope 30 is sleeved on the rope guiding pulley 68c, an inner manipulator guide pulley 68f is rotatably provided on each of upper and lower portions of the inner manipulator 68a, the inner manipulator guide pulley 68f contacts the front glass 65 on the side facing the rear glass 66, a set of inner manipulator magnet blocks 68g is provided in the middle of the inner manipulator 68a, the outer manipulator 68b also has outer manipulator magnet blocks, since the outer manipulator magnetic block is magnetically attracted to the inner manipulator magnetic block 68g via the front glass 65, the inner manipulator 68a is moved up or down by the outer manipulator 68 b. In order to save labor and prevent the blind 8 from sliding abnormally, a weight support 68h is inserted into the lower portion of the inner actuator 68a, and a weight 68i is connected to the lower portion of the weight support 68h by a screw as shown in fig. 5.

Referring to fig. 6, the above mentioned curtain turning traction rope tensioning device 40 arranged on the second corner connector ii 7 of the frame strip at the lower right corner of the window is shown in fig. 6, and the detailed structure or combination of the components of the curtain turning traction rope tensioning device 40 can be understood by the applicant reading the above mentioned patent documents in the background art column, and thus will not be described in detail.

When the curtain sheet is to be turned over (the inner turning or the outer turning may also be called as an upper turning or a lower turning), the operator pulls the outer manipulator 68b slidably engaged with the outer manipulator guide bar 651 (shown in fig. 1) attached to the front glass 65, the outer manipulator 68b drives the inner manipulator 68a, the inner manipulator 68a drives the curtain sheet turning traction rope 20 by following the sliding movement of the right vertical frame bar groove 67d, the curtain sheet turning traction rope 20 drives the turning wheel 41, the turning wheel 41 drives the turning wheel shaft 4, the turning wheel shaft 4 drives the curtain sheet turning shaft 10 through the turning wheel shaft linkage and the release mechanism 5, the curtain sheet turning shaft 10 drives the turning drum 9, and the turning drum 9 drives the curtain sheet ladder rope 81, thereby turning the curtain sheet 83. Since the process of lifting the blind 8 belongs to the known art, it is not described in detail.

In the above process, since the torsion spring 53 of the structural system of the turnover axle linkage and release mechanism 5 is tightly sleeved on the left end of the turnover axle 4, and since the right end of the torsion spring actuation plate axle 51 is rotatably inserted into the torsion spring actuation plate axle insertion hole 42, and since the torsion spring actuation plate 52 corresponds to the space between the first torsion spring foot i 531 and the second torsion spring foot ii 532, when the turnover wheel 41 is driven by the curtain turnover traction rope 20, as mentioned above, the turnover axle 4 is driven by the turnover wheel 41, the torsion spring 53 is driven by the turnover axle 4 to correspondingly rotate with the turnover axle 4 by a certain angle, when the second torsion spring foot ii 532 contacts with the front side of the torsion spring actuation plate 52 and then rotates with the turnover axle 4, the torsion spring actuation plate 52 is driven by the second torsion spring foot ii 532 and the torsion spring actuation plate axle 51 is driven by the torsion spring actuation plate 52 to correspondingly rotate by a certain angle, since the right end of the curtain turnover axle 10 is fixedly inserted into the turnover axle insertion hole 511 of the torsion spring actuation plate axle 51, therefore, the curtain sheet turning shaft 10 is driven to correspondingly rotate a certain angle in the process of rotating the torsion spring actuating plate shaft 51 by a certain angle, namely, the curtain sheet turning shaft 10 drives the turning drum 9 to turn the curtain sheet 83. If the curtain 83 is still turned to the limit, and the curtain turning traction rope 20 is further pulled, i.e. the outer manipulator 68b is further pulled, then since the second torsion spring leg ii 532 is in the state blocked by the aforementioned torsion spring leg blocking plate 216, the torsion spring actuating plate 52 is no longer driven by the second torsion spring leg ii 532 in this state, and since the second torsion spring leg ii 532 is blocked by the torsion spring leg blocking plate 216, the torsion spring 53 is forced to be in the loose state, i.e. no longer tightly embracing the turning wheel shaft 4, and thus the torsion spring actuating plate 52 is not further driven to rotate by the second torsion spring leg ii 532, the torsion spring actuating plate shaft 51 is also in the static state, and the turning wheel 41 is in the idle state because the turning wheel shaft 4 is not tightly embraced by the torsion spring 53, i.e. the state that the torsion spring 53 temporarily abandons the embracing and fixing state of the turning wheel shaft 4. Since the curtain 83 is turned in the direction opposite to the above direction only by operating (pulling) the outer manipulator 68b in the direction opposite to the above direction, the description thereof is omitted.

In the process that the inner controller 68a drives the blind lifting traction rope 30 to move, since the front end and the rear end of the blind lifting traction rope transition roller 3 are inserted into the hidden transition roller end and then inserted into the groove 221, there is no well-defined gap between the end of the blind lifting traction rope transition roller 3 and the wall of the blind lifting traction rope transition roller cavity 22, so that the blind lifting traction rope 30 is not rubbed at this position, and this structure can meet the sleeving requirement of a plurality of strands of structural forms or thicker blind lifting traction ropes 30 under a wide window condition.

In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
