Description

Technical Field

[0001] The invention relates to the field of doors and windows, and in particular to a steel wire adjustment mechanism for heavy-duty sliding doors and windows. Background Art

[0002] Sliding doors and windows serve as the main channels for indoor ventilation and lighting. The existing sliding doors and windows are getting larger and larger in size, and there is a trend of gradually replacing traditional walls. As the size of sliding doors and windows increases, their weight also increases. With the development of smart homes, more and more sliding doors and windows use motors to achieve automatic opening and closing of sliding doors and windows. Existing motor-driven sliding doors and windows generally use the method of motor-driven synchronous belt rotation to drive the movement of the sliding fan. The synchronous belt will temporarily occupy a larger space when installed on the sliding fan, thereby increasing the thickness of the window frame, which will increase the production cost on the one hand, and the appearance of the sliding doors and windows will also appear very bulky on the other hand. Moreover, for large sliding fans, the use of synchronous belts to drive the opening and closing of the sliding fans requires extremely high precision, otherwise it will affect the airtightness and closing effect of the sliding fans when they are closed, and as the length of the synchronous belt increases, it is also inconvenient to adjust the sliding doors and windows during installation. Summary of the invention

The small size and high concealment of the steel wire ensure the beauty of the doors and windows. At the same time, the upper and lower clamps on the adapter can connect the open-loop synchronous belt to a closed-loop state, which greatly facilitates the installation of the synchronous belt and eliminates the cost of customizing the synchronous belt, thereby reducing the production cost of doors and windows. At the same time, the open-loop synchronous belt can be cut at will according to the size of the doors and windows, which facilitates the installation of doors and windows;

[0014] (3) By setting the positioning wheel group, the exposed steel wire can be close to the top of the frame, eliminating the exposure of the driving mechanism, ensuring the beauty of the window sash, and facilitating the positioning of the steel wire, greatly improving the convenience of steel wire installation;

[0015] (4) By installing an adjustment device on the top of the sliding sash, the adjustment device can effectively avoid affecting the appearance of the doors and windows. At the same time, the adjustment device can conveniently adjust the tightness of the steel wire, which can effectively ensure the stability of the steel wire transmission. In addition, the adjustment device is fixed on the sliding sash, and when the steel wire moves, the sliding sash can be easily opened and closed;

[0016] (5) Since the tightness of the steel wire can be fine-tuned through the adjustment device, the accuracy of cutting the steel wire for doors and windows can be reduced during the installation process, making the installation of the steel wire more convenient;

[0017] (6) By setting an adjuster on the synchronous wheel, the height of the synchronous wheel and the distance between the two synchronous wheels can be easily adjusted, so that the tightness and position of the synchronous belt can be adjusted after the synchronous belt is spliced ​​into a closed loop, which greatly facilitates the installation of the synchronous belt.

DETAILED DESCRIPTION

[0028] Example

[0029] like Figure 1 to Figure 8As shown, the heavy-duty sliding door and window steel wire 45 adjustment mechanism provided in this embodiment includes a frame 1, a fixed fan 2, a sliding fan 3 and a driving mechanism 4, the frame 1 is equipped with a fixed fan 2 and a sliding fan 3, the sliding fan 3 can be installed translationally on the frame 1 on the side of the fixed fan 2 close to the room, the top of the frame 1 is provided with a driving mechanism 4 for driving the sliding fan 3 to open and close, the driving mechanism 4 includes a synchronous wheel 41, a synchronous belt 42, an adapter 43, a positioning wheel group 44, a steel wire 45 and an adjusting device 46, the frame 1 has synchronous wheels 41 at both ends, and synchronous belts 42 are wound around the two synchronous wheels 41. The synchronous belts 42 are supported by the two synchronous wheels 41 and rotate on the two synchronous wheels 41. The synchronous belts 42 are open-loop synchronous belts 42. The two ends of the synchronous belts 42 are connected by adapters 43 to form a closed loop. The open-loop synchronous belts 42 are easy to install and can save the cost of stocking synchronous belts 42 of different sizes for manufacturers, thereby reducing the backlog of goods. The frame 1 is provided with a motor 5 for driving the synchronous belts 42 to rotate around the synchronous wheels 41. The motor 5 It can be installed on one of the synchronous wheels 41 to make the layout in the frame 1 more concise. The frame 1 on one side of the two synchronous wheels 41 is respectively processed with a through groove 11 that vertically penetrates the frame 1 and is aligned with the push-pull fan 3. A positioning wheel group 44 is installed in each through groove 11. A steel wire 45 is wound around the positioning wheel group 44. The two ends of the steel wire 45 are fixed to the top of the push-pull fan 3 near the room through an adjustment device 46. By processing the through groove 11 on the frame 1, only the steel wire 45 of the driving mechanism 4 is exposed, and the straightness of the steel wire 45 is The diameter is much smaller than the width of the synchronous belt 42. If you don't observe carefully, it will not affect the appearance of the window sash. The adapter 43 is connected to the steel wire 45. Through the adapter 43, the synchronous belt 42 can drive the steel wire 45 to drag the sliding fan 3 to open and close when it rotates. When in use, the motor 5 drives the synchronous belt 42 to rotate, and the adapter 43 installed on the synchronous belt 42 drags the steel wire 45 to move, thereby realizing the movement of the sliding fan 3. Since the sliding fan 3 is inconvenient to lock, it is necessary that a lock for locking the sliding fan 3 is provided on the frame 1.

[0030] In order to ensure that the steel wire 45 moves with the synchronous belt 42, the adapter 43 is designed as follows: the adapter 43 includes a slider 431, a connecting plate 432, a lower clamping block 433, an upper clamping block 434 and a fastening block 435. A slide groove 12 is processed in the frame 1 for the slider 431 to slide back and forth between the two synchronous belts 42. The slider 431 can be limited by the slide groove 12 to prevent the adapter 43 from causing deviation during movement, thereby affecting the movement path of the steel wire 45. A connecting plate 432 is installed on the slider 431. A lower clamping block 433 and an upper clamping block 434 connecting the two ends of the open-loop synchronous belt 42 are arranged above the connecting plate 432. The upper clamping block 434 and the lower clamping block 433 can clamp the two ends of the synchronous belt 42 to form a closed-loop structure, and at the same time can reduce the enterprise's Stocking cost. During the assembly process of doors and windows, it is only necessary to cut the appropriate synchronous belt 42 according to the spacing between the two synchronous wheels 41. Under the action of the upper clamping block 434 and the lower clamping block 433, the synchronous belt 42 can form a closed-loop structure, which greatly simplifies the installation of the synchronous belt 42. One end of the connecting plate 432 extends toward the steel wire 45, and the extended end of the connecting plate 432 is connected to a fastening block 435 fixedly connected to the steel wire 45. The fastening block 435 is processed with a through hole 436 for the steel wire 45 to pass through, and the side wall of the fastening block 435 is provided with a locking screw 437 that connects the steel wire 45 and the fastening block 435 as a whole. The locking screw 437 can ensure the fixing effect of the steel wire 45 and the fastening block 435 to avoid the steel wire 45 not following the movement of the synchronous belt 42.

[0031] In order to prevent the steel wire 45 from rubbing against the frame 1, the positioning wheel group 44 of the present scheme is designed as follows: the positioning wheel group 44 includes a supporting shell and two limiting wheels installed in the supporting shell; the supporting shell is installed in a through groove 11 processed on the frame 1 and is flush with the top and bottom surfaces of the through groove 11 to avoid exposure; a limiting groove matching the contour of the steel wire 45 is processed on the annular surface of the limiting wheel; the heights of the two limiting wheels are different; the bottom annular surface of one limiting wheel is located below the frame 1, and the top annular surface of the other limiting wheel is located above the frame 1 and aligned with the through opening 436 on the fastening block 435; the use of two limiting wheels can reduce the diameter of the limiting wheel. On the one hand, it can reduce the exposed area of ​​the limiting wheel; on the other hand, it can make it suitable for doors and windows of various models, reducing the company's stocking costs.

[0032] Since a large force is required to tighten the steel wire 45, in order to facilitate the adjustment of the tightness of the steel wire 45, the adjusting device 46 includes a fixed block 461 and an adjusting block 462. The tops of the fixed block 461 and the adjusting block 462 are respectively processed with through holes 463 connected to the two ends of the steel wire 45. The fixed block 461 is fixed to the top of the sliding fan 3 by screws, and the adjusting block 462 is provided with an adjusting bolt 464 connected to the side wall of the fixed block 461. The distance between the adjusting block 462 and the fixing hole can be adjusted by adjusting the bolt 464. When in use, it is only necessary to press the two ends of the steel wire 45 into the through holes 463 on the fixed block 461 and the adjusting block 462 respectively, and then the adjusting bolt 464 is used to move the adjusting block 462 toward the fixed block 461, so that the steel wire 45 can be easily tightened, making the installation process of doors and windows easier.

[0033] Since the synchronous belt 42 is easy to loosen after installation, in order to ensure the transmission efficiency of the motor 5, an adjuster 6 is provided on one of the synchronous wheels 41. The adjuster 6 is preferably installed on the synchronous wheel 41 without the motor 5 installed, so as to ensure the stability of the installation of the motor 5. The adjuster 6 includes a fixed plate 61, a vertical adjustment plate, a horizontal adjustment plate 63 and an adjustment screw 64. The fixed plate 61 is fixed on the inner wall of the frame 1. A vertical adjustment plate is provided on one side of the fixed plate 61. A plurality of vertically arranged strip grooves 65 are processed on the vertical adjustment plate. The vertical adjustment plate can move up and down on the fixed plate 61 through the vertically arranged strip grooves 65. The vertical adjustment plate is installed on one side There is a horizontal adjustment plate 63, on which a plurality of horizontally arranged strip grooves 65 are processed. The horizontal adjustment plate 63 can be horizontally moved on the vertical adjustment plate through the horizontally arranged strip grooves 65. A rotatable synchronous wheel 41 is installed on the side wall of the horizontal adjustment plate 63. When in use, the height of the corresponding synchronous wheel 41 and the distance between the two synchronous wheels 41 can be adjusted through the strip holes on the vertical adjustment plate and the horizontal adjustment plate 63. The vertical adjustment plate and the horizontal adjustment plate 63 are both processed with bent adjustment parts, and the adjustment parts are provided with adjustment screws 64. The tightness of the synchronous belt 42 can be adjusted by adjusting the screws 64 after the synchronous belt 42 is installed.

[0034] The method of using the present invention is:

[0035] When in use, the frame 1 is installed on the corresponding wall, and then the fixed fan 2 and the sliding fan 3 are installed on the frame 1, and then the driving mechanism 4 for driving the sliding fan 3 to move is installed in the space at the top of the frame 1. The driving mechanism 4 is installed in sequence by installing two synchronous wheels 41 and a motor 5 for driving the synchronous wheels 41 to rotate inside the two ends of the frame 1, and then the synchronous belt 42 of the corresponding length is cut and wound around the two synchronous wheels 41, and the two ends of the synchronous belt 42 are connected to form a closed-loop synchronous belt 42 through the upper clamping block 434 and the lower clamping block 433 on the adapter 43, and then the steel wire 45 of the corresponding length is passed through the opening 436 on the fastening block 435, and the two ends of the steel wire 45 are respectively passed around the corresponding positioning wheel group 44 and then connected to the corresponding fixed block 461 and the adjusting block 462, and then the fixed Block 461 is fixed on the side wall of the sliding fan 3 facing the indoor top, and the adjusting block 462 is installed on the side wall of the fixed block 461 by adjusting bolts 464, and then the steel wire 45 is tightened by adjusting bolts 464, and the synchronous belt 42 is tightened by adjusting screws 64 on the regulator 6 to complete the assembly of the sliding doors and windows. Finally, the sliding doors and windows are debugged, and the motor 5 is started. The motor 5 drives the synchronous wheel 41 to rotate, and the synchronous wheel 41 drives the synchronous belt 42 to rotate when it rotates. Under the action of the adapter 43, the steel wire 45 moves with the synchronous belt 42. Since the steel wire 45 is connected to the fastening block 435 on the adapter 43 by locking screws 437, its two ends are fixedly connected to the sliding fan 3. When the steel wire 45 moves, it will drag the sliding fan 3 to move, so as to realize automatic opening and closing of the doors and windows.

[0036] This solution is applicable to sliding doors and sliding windows. When applied to sliding doors or sliding windows, the assembled fixed leaf 2 can be used as a transparent wall, while the sliding leaf 3 is used as an openable door leaf or window leaf.

[0037] When installing doors and windows, the fixed fans 2 can be replaced with sliding fans 3 by only installing another set of driving mechanisms 4. It should be noted that when all the sliding fans 3 are installed in the frame 1, the profiles close to the outdoor frame 1 need to be processed to block the steel wires 45 to ensure safety.

[0038] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitation of the present invention.
