Description

Bead-chain driven double-glazed built-in shutters

technical field

The invention belongs to the technical field of sunshade hollow glass products, in particular to a bead chain driven double-layer hollow glass built-in shutter.

Background technique

The double-layer hollow glass built-in blinds mentioned above refer to the construction of a venetian blind that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass) that are arranged in a face-to-face state and that seal the surrounding edges. A window belonging to the category of sunshade hollow glass products. This kind of window has the following self-evident advantages: good heat insulation, so as to reflect the energy saving of the building; excellent sound insulation, so as to avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained, privacy can be protected, and the venetian blinds can be protected from dust to reflect the excellent no-cleaning effect; The building has an ideal embellishment to improve the grade of the building; strong impact resistance, good safety and long service life to meet the installation requirements of high-rise buildings and meet the ultimate long-term maintenance-free requirements; easy to use, light and labor-saving In order to adapt to the operation of people of different ages and different physical abilities, etc.

The technical information about the built-in shutters of double-layer insulating glass can be found in the published Chinese patent documents, such as CN2564720Y (hollow glass with built-in blinds), CN2767624Y (shutters in insulating glass), CN2767625Y (insulating glass in hollow glass with improved structure) Shutters), CN2756796Y (shutters inside insulating glass), CN2232968Y (integral door and window leaf with horizontal shutters in double-layer glass), CN2297952Y (magnetically driven double-layer telescopic curtain), CN2326718Y (fully enclosed shutters), CN100535378C (louver in hollow glass with improved structure), CN102444372A (hollow venetian blind with built-in sunshade), CN2752414Y (louver in insulating glass), CN2623860Y (louver in hollow glass), CN104747054A (double-glazed built-in louver), etc. wait.

It can be seen from the reading of the patent documents that are not limited to the above examples that the lifting of the venetian blind arranged between the two glasses is realized through the operation of the venetian blind lifting controller located outside the double-layer glass. Specifically, When the operator moves up the venetian blind lifting controller that is in contact with the inner glass, it will drive the traction inner slider located between the double-layer glass to go up, and the venetian blind will go down, and vice versa. Because the venetian blind lifting controller located outside the glass and the traction inner slider located inside the glass are attracted together through a set of magnetic blocks through the inner glass (the glass facing the room in the use state), and because it is located inside the glass The traction inner slider is connected with the venetian blind through the traction rope (the traction rope includes the curtain flipping traction rope and the venetian blind lifting traction rope). For this, please refer to the last paragraph on page 7 of the aforementioned CN100535378C specification (this patent will Curtain lift controls are called "magnetic iron outer sliders").

The above-mentioned double-layer hollow glass built-in blinds need to be equipped with a set of magnets on the venetian blind lift controller and the traction inner slider, so that the two can be attracted together through the inner glass, so it can be called a magnet-driven double-layer blind. Insulated glass with built-in shutters. Although the double-layer hollow glass built-in blinds of this structural system can meet the actual use requirements, there are the following shortcomings: First, due to the fact that each group of magnets that are usually equipped on the blinds lifting controller and the traction inner slider The quantity is at least three or more, and the magnet is a strong magnet, and because the price of this magnet is very expensive, the blinds are not economical and cheap; second, because the volume of the blind lift controller is limited, it is not conducive to operation. Thirdly, because a group of magnets are embedded in the outer slider housing of the shutter lift controller made of plastic and the inner slider embedded in the traction inner slider Inside the casing, because the magnet and the casing are made of different materials, the coefficients of thermal expansion and contraction are different and the difference is large, and because the plastic is naturally aged and even deformed due to a long period of time, after a certain period of use, the casing will not The control ability of the magnet is gradually weakened, and even the phenomenon of magnet dislocation and falling off occurs, which affects the mutual magnetic attraction effect between the blind lifting controller and the traction inner slider; fourth, because the magnet is a rare earth permanent magnet, and rare earth is a valuable strategic resource , so there is a problem of large resource consumption.

Aiming at the above-mentioned prior art, it is necessary to make a reasonable improvement, for which the applicant has made a positive and beneficial design, and has formed a technical solution to be introduced below.

The cross-sectional shapes of the aforementioned overturning shaft inserting and fixing holes 2311 , the curtain overturning shaft matching holes 2532 and the curtain overturning shaft 22 are the same.

In this embodiment, although the applicant has mentioned that the number of the driving guide seat 25 of the blind flipping rope is a pair, if the width of the venetian blind 3 is wide, the adaptability can be increased, and the venetian blind lifting traction rope 6 and The same example for the curtain sheet overturning rope 31 and even the lifting traction rope giving way hole 25114.

In this embodiment, the cross-sectional shape of the above-mentioned overturning shaft inserting and fixing hole 2311, the curtain overturning shaft matching hole 2532 and the curtain overturning shaft 22 is D-shaped, and the D-shaped here is a semicircle, but Also can all be rectangle or square.

When the inner control mechanism 4 is driven by the outer control mechanism 5, and the timing belt 44 of the structural system of the inner control mechanism 4 drives the curtain turning shaft synchronous pulley 23 of the structural system of the curtain turning mechanism 2, the turning shaft of the curtain turning The synchronous pulley 23 drives the curtain flipping shaft 22 . Since the curtain turning drive shaft 253 is fixed to the curtain turning shaft 22 through its matching hole 2532, and because the curtain turning drive shaft sleeve 252 is empty (that is, rotatably set) on the curtain turning drive shaft 253 , also because the curtain reversing rope 31 of the venetian blind 3 generates a closing force on the expansion groove 2523, and the larger the size of the venetian blind 3, the heavier the weight, and the greater the closing force generated by the curtain reversing rope 31 on the expansion groove 2523, The cohesive force of the hole wall of the curtain turning drive shaft matching hole 2521 on the curtain turning driving shaft 253 is correspondingly greater, that is, the friction force between the hole wall of the curtain turning driving shaft matching hole 2521 and the curtain turning driving shaft 253 The corresponding is larger, so when the curtain turning drive shaft 253 is driven by the curtain turning shaft 22 through its frictional fit with the curtain turning drive shaft matching hole 2521 to drive the curtain turning drive bushing 252 to rotate, the The curtain overturning driving bushing 252 drives the curtain overturning rope 31 through the tongue plate 2524 wrapped around the curtain overturning rope. The curtain 32 until the curtain 32 is turned to the desired degree (angle). For example, when the curtain 32 is closed, the limit step 2522 of the curtain turning drive bushing 252 is just at the position that matches the limit step stopper 25112, that is, the limit step 2522 is formed by the limit stopper 25112. block. Thus, even if under the action of the synchronous belt 44, the curtain turning shaft 22 is then rotated by the timing belt pulley 23 and the curtain turning shaft 22 then drives the curtain turning drive shaft 253, due to the closing force of the expansion groove 2523 It is not enough to control the rotation of the curtain turning drive shaft 253, so the curtain turning driving shaft 253 gets rid of the control bundle of the curtain turning driving bushing 252 and rotates with the curtain turning shaft 22 alone, while the curtain turning driving shaft The cover 252 is in a static state and will not act on the curtain flipping rope 31, which is beneficial to protect the curtain flipping rope 31. On the other hand, since the movement resistance of the synchronous belt 44 is significantly reduced, the matching resistance between the synchronous belt 44 and the curtain turning shaft synchronous pulley 23 can be alleviated, and the protection of the synchronous belt 44 and the curtain turning shaft synchronous pulley 23 Both are positive. When the synchronous belt 44 drives the synchronous pulley 23 of the overturning shaft of the curtain to move clockwise or counterclockwise, the curtain 32 is opened or closed.

Focusing on Fig. 1, the aforementioned traction rope transition mechanism 7 includes a transition wheel seat 71 and a transition wheel 72, the transition wheel seat 71 is fixed with the aforementioned lower horizontal tube right corner joint 122 in an inserting manner, and the transition wheel 72 is positioned corresponding to the transition wheel The seat 71 is rotatably supported on the transition wheel seat 71 towards the position of the side of the right vertical pipe 14 of the aforementioned window, and a transition wheel guide rope 721 is sleeved on the transition wheel 72, and the two ends of the transition wheel guide rope 721 are connected to The middle part of the aforementioned shutter lifting traction rope 6 is connected. The reason for using the transition wheel guide rope 721 is because it has been mentioned above: there are a pair of curtain turning rope drive guide seats 25 in the structural system of the curtain turning mechanism 2, so there are two blind lifting traction 6 , and the transition wheel guide rope 721 that is placed on the transition wheel 72 only needs one. It can be seen from the above description that one end of the blind lifting traction rope 6 is fixed to the lifting traction rope driving wheel 45 (also called the twisted rope wheel) at the position corresponding to the lifting traction rope fixing hole 453 on the lifting traction rope driving wheel 45, The other end successively passes through the transition wheel 72 (the transition wheel guide rope 721 is placed on the transition wheel 72), the lifting traction rope of the curtain turning mechanism 2 is redirected to the guide wheel 24, the lifting traction rope give way hole 25114 (shown in Figure 3), The lifting traction rope transition guide wheel 254 (shown in Figure 3) and the curtain sheet traction rope give way to the hole 321 are fixed with the bottom bar.

The applicant describes the working principle of the present invention with reference to FIGS. 1 to 4. When the venetian blind 3 is to be retracted upward, the user pulls the bead chain 55 of the outer control mechanism 5 in a clockwise direction, and the beads on the bead chain 55 Drive the bead chain wheel hub 54 , the hub pivot support stack ring 541 of the bead chain wheel hub 54 rotates with the hub cavity 521 of the friction disc 52 as a carrier, and the bead chain wheel hub 54 drives the bead chain wheel shaft 53 at the same time. Because the bead chain wheel shaft 53 is connected with the synchronous pulley shaft 431 of the synchronous pulley 43 of the inner control mechanism 4, that is, the bead chain wheel shaft 53 is inserted in the bead chain wheel shaft connection hole 4311 of the synchronous pulley shaft 431, thus the bead chain wheel shaft 53 drives the synchronous The pulley shaft 431 drives the synchronous pulley 43 by the synchronous pulley shaft 431 . Since the synchronous pulley gear 432 on both sides of the synchronous pulley 43 is engaged with the drive wheel gear 452 , the drive wheel gear 452 is driven by the synchronous pulley gear 432 . And because the driving wheel gear 452 is formed on the both sides of the hoisting traction rope driving wheel 45, thereby the hoisting traction rope driving wheel 45 is driven by the driving wheel gear 452. Also because one end of the blind lifting traction rope 6 is fixed with the lifting traction rope drive wheel 45 at a position corresponding to the lifting traction rope fixing hole 453, the lifting traction rope is passed through the blind lifting traction rope during the counterclockwise rotation of the lifting traction rope driving wheel 45. One end of 6 winds the blind lifting traction rope 6 gradually on the lifting traction rope drive axle 451. In this process, since the other end of the venetian blind lifting traction rope 6 passes through the transition wheel 72 of the traction rope transition mechanism 7 (through the transition wheel guide rope 721), the lifting traction rope redirects the guide pulley 24 (self-retrofit guide pulley support cavity 211) The bottom of the lifting traction rope is guided to the guide wheel 24), the lifting traction rope give way hole 25114, the lifting traction rope transition guide wheel 254, the rope hole 25111 and the curtain traction rope give way hole 321 are fixedly connected with the bottom bar, so in the blind The bottom bar is displaced upwards under the receiving rope of the curtain lifting traction rope 6 until the venetian blind 3 is upwardly gathered to the required degree. Since the process of unfolding the venetian blind 3 is opposite to the aforementioned process of retracting it, the applicant will not describe it again.

Since the principle of the angle reversal of the slats 32 of the venetian blind 3 has been described above, it will not be described again.

In summary, the technical solution provided by the present invention overcomes the deficiencies in the prior art, completes the task of the invention, and faithfully realizes the technical effect described by the applicant in the above technical effect column, which is an ultimate technology plan.
