Description
Technical Field
The utility model belongs to the technical field of sunshade cavity glassware, concretely relates to institutional advancement's manual magnetic drive cavity glass embeds shutter.
Background
The aforementioned hollow glass built-in louver mainly refers to, but is not absolutely limited to, a double-layer hollow glass built-in louver (hereinafter the same applies), and for example, there are also a plurality of layers such as three-glass two-chamber hollow glass built-in louver. 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; strong impact resistance, good safety and long service life, thereby meeting the installation requirements of high-rise buildings and the extremely long-term use and maintenance-free requirements, and the like.
Technical information on a hollow glass built-in louver is not known 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), 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.
Common features of the hollow glass built-in blind, not limited to the above examples, are: the turnover of the curtain sheet and the lifting of the blind are realized by hand driving operation, namely, the turnover of the curtain sheet and the lifting of the blind are realized by manual operation of a manual operation mechanism. The components of the structural system of the manual operating mechanism comprise an inner manipulator and an outer manipulator, the outer manipulator which is arranged on one side of the inner glass back to the outer glass in a vertically moving mode is magnetically attracted together with the inner manipulator arranged between the inner glass and the outer glass through the inner glass, a turnover shaft driving device corresponding to the upper part of the inner manipulator is connected with a turnover shaft of the structural system of the curtain turnover and shutter lifting actuating mechanism, a curtain turnover traction rope is connected with a rope winding wheel of the structural system of the inner manipulator and the turnover shaft driving device and a curtain turnover traction rope tensioning device corresponding to the lower part of the inner manipulator, so that when a user moves the outer manipulator upwards or downwards, the outer manipulator drives the inner manipulator to correspondingly move upwards and downwards, the inner manipulator drives the curtain turnover traction rope, and the curtain turnover traction rope drives the rope winding wheel of the structural system of the turnover shaft driving device, because the turning shaft is fixedly inserted with the rope winding wheel, the rope winding wheel drives the curtain piece to turn and the shutter lifting actuating mechanism to move, so that the curtain piece can be turned as required or the shutter can be lifted as required.
From the above description, it can be seen that: if the blind slats are turned to a certain angle to meet the lighting requirement in a room and the blind slats are raised or lowered as required, the blind slats must be moved up or down by the user by dialing the aforementioned external controller, and the operation mode determined by the structure is the mode generally defaulted and accepted by the majority of users, but the operation mode has at least the following technical problems objectively: first, if the aforementioned inner and outer manipulators are mismatched with each other in terms of attraction force for attracting each other across the inner glass and the mass (weight) of the blind between the inner and outer glasses, for example, the attraction force is too small, abnormal sliding occurs and the blind cannot be reliably maintained at the desired raised position, whereas the operation is laborious and the cost of the inner and outer manipulators is increased blindly, since increasing the number of permanent magnets, which are relatively expensive, and/or increasing the volume of the permanent magnets inevitably increases the cost significantly; secondly, as long as the situation that the outer controller is manually moved is existed, the manual operation is relatively laborious, especially, the larger the breadth width of the blind is, the heavier the whole weight of the blind is, the stronger the magnetic attraction force of the mutual attraction of the inner controller and the outer controller is, which is very embarrassing for the weak such as the young and the old; thirdly, once the inner manipulator has the situation of affecting sliding such as displacement, deformation and clamping stagnation, the repair is quite troublesome, the inner manipulator needs to be repaired by a manufacturer or an original installer or a professional, the repair usually needs to remove the inner glass, the work load is large, the time is long, the payment cost is high, and in consideration of the factors, a user is usually unwilling to maintain and use the inner manipulator, so that the inner manipulator is placed and even burdensome; fourthly, the lighting area is affected to a certain extent due to the need of providing the inner manipulator with a channel which slides up and down.
The 'electric rotary magnetic transmission built-in sunshade hollow glass' recommended by the Chinese invention patent application publication No. CN110513023A can make up for the above-mentioned deficiencies of the applicant to a certain extent due to the adoption of an external magnetic transmission electric manipulator and a driven magnetic transmission piece in a cavity, but the patent application still has the following disadvantages: firstly, since this patent teaches in paragraph 0029 that the motor is provided with special positioning grooves and ribs to position the motor in the housing (referred to as "housing seat"), the structure of the motor is relatively complicated, which is troublesome for the manufacturer of the motor and the manufacturer of the hollow built-in louver, and the complexity of the structure of the motor increases the cost of the motor; secondly, because no suggestion is given on how to reasonably fix the shell together with the motor, the non-metallic isolator, the magnetic column and the like which are installed in the shell and the inner glass of the hollow glass built-in shutter under the use state, the magnetic attraction of the magnetic column (namely the outer magnetic column) of the external magnetic-driven electric controller on the magnetic column (namely the inner magnetic column) of the structural system corresponding to the driven magnetic transmission piece in the cavity is not perfect enough, for example, once the external magnetic controller is subjected to impact or collision by abnormal external factors to cause deviation or even fall off, the re-matching effect of the external magnetic controller and the inner magnetic column can be influenced, and especially for a user, the problem of taking measures is often generated; thirdly, although the patent in paragraph 0028 mentions the content of the power line connecting the power source, it also does not give any hint how to make the motor work, such as how to supply power to the motor, how to operate the indispensable components of the motor, how to arrange the indispensable components in the housing along with the motor, etc.; fourthly, according to the information of the motor mentioned in the specification, the driving mode of the patent is required to depend on a power supply, thereby causing the structure to be complicated, increasing the cost and increasing the maintenance difficulty in daily use, for example, as a user can not objectively perform substantive repair on a controller for controlling the operation of the motor and the motor itself; when the width of the venetian blind is large, especially the window width (also called "window width") of modern buildings is relatively large and tends to increase continuously, so that the width (also called "door width") of the venetian blind matched with the venetian blind is correspondingly increased, and therefore, the motor volume and the power of the structural system of the external electro-dynamic magnetic controller called in the patent are necessarily increased, and the diameter and the number of the magnetic columns are simultaneously increased under the condition of increasing the motor and the power, so that the volume of the whole external magnetic transmission motor controller is increased, and the manufacturing cost is obviously increased, and the economy is lost.
The bead chain driven double-layer hollow glass built-in shutter provided by the Chinese invention patent CN105041172B reasonably makes up the defects of the hollow glass built-in shutter in the prior art summarized in the background field of the specification, and objectively realizes the four advantages stated in the technical effect field of the specification. However, the patent has the disadvantage of relatively complicated structure due to many links in motion transmission, and also has the fear that the limbs of people, especially the neck of the young people, may be tied due to the free swinging of the long and ring-shaped bead chain rope (commonly called as "bead chain" or "bead chain", the same applies hereinafter). In addition, as for national standard requirements, the annular curtain pull rope (including the pull bead chain) is not allowed to freely float (shake) in a non-positioning mode so as to ensure safety.
In view of the above-mentioned prior art, there is a need for improvement, for which the applicant has made an active and advantageous design, against the background of which the solution to be described below is made.

Preferably, a pair of key projections 918 (i.e., "key projections") may be formed in the longitudinal direction of the spool 92, and the key projections 918 are spaced apart by 180 ° around the circumferential direction of the spool 92, i.e., in a face-to-face positional relationship. The pair of key protrusions 918 has a good anti-floating function for the pair of blind lifting traction ropes 101, and provides a condition for realizing key fixation for the driving gear 923 (see fig. 7 in particular).

Of course, if the position of the upper horizontal frame cavity sealing sheet 71111 corresponding to the support frame fixing groove 915 at the front side of the pair of reel support seats 91 has a convex strip, the support frame fixing groove 915 at the front side of the pair of reel support seats 91 can be engaged with the convex strip (not shown in the figure) on the upper horizontal frame cavity sealing sheet 71111 for shielding the upper horizontal frame cavity 7111, so as to achieve the front and rear engagement of the pair of reel support seats 91, in this case, the front and rear sides of the pair of reel support seats 91 must have the support frame fixing groove 915.

A locking protrusion 9417 is formed at the bottom of the base 941, and a locking protrusion slot 94171 is formed around the locking protrusion 9417, and the locking protrusion slot 94171 is locked with the bottom wall of the upper cross frame bar cavity 7111.

Continuing to refer to fig. 10 and 11 in conjunction with fig. 1, applicant does not repeat the description since the pair of base slots 9413 mentioned above function exactly the same as the support base frame securing slots 915 described above. When the pair of curtain sheet turnover devices 94 are disposed in the upper cross frame cavity 7111 of the upper cross frame 711 shown in fig. 1, as described above, the locking protrusion slots 94171 formed on both sides of the locking protrusion 9417 at the bottom of the base 941 are engaged with the bayonet formed on the bottom wall of the upper cross frame cavity 7111. The pair of blind lifting pulling ropes 101 pass through the pulling rope through holes 9414 and the blind lifting pulling rope direction-changing wheels 943 and then reach the supporting seat blind lifting pulling rope guide wheels 916. Since the blind lifting/lowering traction rope bend wheel 943 is rotatably supported on the bend wheel shaft 9431 by the pair of bend wheel rotation support bearings 94321, the blind lifting/lowering traction rope bend wheel 943 can freely rotate, so that the resistance is remarkably reduced, the severe friction between the pair of blind lifting/lowering traction ropes 101 and the blind lifting/lowering traction rope bend wheel 943 can be avoided, and the advantages of small operation resistance and high speed can be realized during manual operation or during the motor driving operation.
The structural system of the lifting and turning actuating mechanism 9 of the venetian blind adopts the winding drum 92 and the rope guiding device 93, and the advantages thereof are at least as follows: the first is that the winding drum 92 drives the rope arranging device 93 to wind the pair of blind lifting pulling ropes 101 on the winding drum 92 or exit from the winding drum 92 in a positive mode in order to avoid rope mess, rope biting and even knotting; secondly, the stability and consistency of the rope winding and unwinding of the pair of lifting traction ropes 101 of the blind curtain can be ensured, so that the curtain sheet 104 of the blind curtain 10 can be prevented from jumping; thirdly, the friction degree of the pair of blind lifting traction ropes 101 in the rope winding and unwinding process is obviously reduced, so that the expected service life is ensured; fourthly, because the curtain turning device 94 is additionally provided with the ladder rope turning wheel limiting seat 944, the escape of the ladder rope turning wheel 942 can be avoided, and the hanging reliability of a pair of curtain turning ladder ropes 102 in the use state is ensured; fifthly, because the front middle part and the rear middle part of the base 941 in the height direction respectively form a pair of base clamp grooves 9413 at corresponding positions, the base 941 can be matched with the raised strips on the rear wall plate of the upper transverse frame strip 711 of the inner frame body 71 of the window body 7 in a use state, the stability of the base 941 is ensured, and front, back, left and right deviation and up and down flutter are avoided; sixth, since the blind lifting/lowering traction rope bend wheel 943 is rotatably mounted on the base 941 via the bend wheel rotation support bearing 94321 and the bend wheel shaft 9431, the blind lifting/lowering traction rope bend wheel 943 can rotate freely, friction between the pair of blind lifting/lowering traction ropes 101 and the blind lifting/lowering traction ropes can be significantly reduced, and not only the operation resistance is small, but also the life of both can be effectively prolonged.
As can be seen from the above description, the magnetic column driven transmission mechanism 2 disposed at the right end of the upper horizontal frame cavity 7111 drives the actuator acting shaft 20 through the built-in torque increasing mechanism 4, the actuator acting shaft 20 drives the rope overturning wheel 942 to make the pair of curtain overturning ropes 102 drive the curtain 104 to overturn, and similarly, the actuator acting shaft 20 drives the winding drum 92, the driving gear 923 at the two ends of the winding drum 92 drives the pair of driven gears 934, the pair of driven gears 934 drives the pair of screw rods 932, the pair of screw rods 932 drives the pair of rope-moving screw sockets 933, because the pair of blind lifting traction ropes 101 pass through the rope-arranging moving screw sleeve blind lifting traction rope guide wheels 9331 arranged on the pair of rope-arranging moving screw sleeve seats 933 respectively and then the end parts of the blind lifting traction ropes are fixed with the fixer fixing lugs 9211 of the fixer 921 of the blind lifting traction rope end, so that the blind lifting rope 101 can be wound on the drum 92 or withdrawn from the drum 92 as required.
When the blind 10 is to be turned over, the operator pulls the bead chain 32, the bead chain 32 drives the bead chain wheel 31, the bead chain wheel 31 drives the driving magnetic pillar device 135 through the bead chain wheel shaft 311, so that the whole driving magnetic pillar device 135 rotates by an angle, the driving magnetic pillar device 135 drives the driven magnetic pillar device 22, the left end of the driven magnetic pillar device 22 drives the main gear 43 through the main gear shaft 431, the main gear 43 drives the first transition gear i 44, and the second transition gear ii 45 drives the driven gear 46 through the transition gear shaft 47 and the second transition gear ii 45. Because the right end of the actuating shaft 20 of the actuating mechanism is connected (inserted and embedded) with the actuating shaft connecting hole 462 of the driven gear 46, the driven gear 46 drives the actuating shaft 20 of the actuating mechanism to rotate for an angle, the actuating shaft 20 of the actuating mechanism drives the actuating mechanism 9 for lifting and turning the blind curtain 10, and the blind curtain 104 of the blind curtain is turned; if the blind 10 is to be raised, the aforementioned blind lifting/lowering cord 101 is wound around the aforementioned drum 92, and vice versa, in the same manner as described above. The slats 104 of the blind 10 are flipped inward or outward (also referred to as "flipped downward or upward") and the blind 10 is raised or lowered depending on the pulling direction of the bead chains 32 by the operator.
Preferably, in the present embodiment, since the actuator acting shaft 20 has a regular hexagonal cross-sectional shape, the left end of the ball sprocket shaft 311 has a regular hexagonal shape, and the right bearing shoe ball sprocket shaft connecting hole 13512, the master gear shaft 431, and the left end hole of the slave magnetic cylinder device 22 have regular hexagonal shapes.
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.
