Description

Manual magnetic drive's built-in shutter of cavity glass

Technical Field

The utility model belongs to the technical field of sunshade cavity glassware, concretely relates to manual magnetic drive's built-in shutter of cavity glass.

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.

After the installation of the blind 10 is completed, i.e., the entire window 7 is completed, the blind 10 needs to be lifted (retracted) upward according to the manufacturing and repair specifications, and the flow is allowed to proceed to the next process. Therefore, after the blind 10 is installed, if it is required to ensure its retracted state, the on-line operator holds (holds) a locking magnet and aligns the magnet block 92 with the inner glass 72, and pulls the magnet block 92 and the entire magnet block holder 91 to the right by the locking magnet, so that the magnet block cylindrical spline hole 931 fits the spline housing 93.
