Description

Technical Field

[0001] This utility model relates to the field of door and window processing technology, specifically to an electric opening device for aluminum alloy door and window processing. Background Technology

[0002] In the precision process of aluminum alloy door and window manufacturing, the electric opening device is a key auxiliary device to meet the convenient opening needs when performing fine processing on the outer frame structure or its complex inner components during door and window processing. The core function of this electric device is to achieve smooth, fast and precise opening and closing of doors and windows through electric drive, providing processing personnel with a spacious operating space.

[0003] In existing technologies, most electric opening devices for aluminum alloy doors and windows on the market currently adopt a design of multiple integrated large suction cups. In actual use, because the integrated large suction cup is an inseparable whole, once one part is damaged, or air leakage occurs during use for various reasons, the suction force of the entire suction cup will drop sharply or even be completely lost instantly. In this case, the door and window that were originally held stable by the suction cup will fall directly due to the loss of support. For the door and window itself, a direct fall may cause deformation of the door and window frame and breakage of the glass, making the door and window unusable and requiring large-scale repairs or even replacement. This not only increases the cost of use, but also causes great inconvenience to users. Utility Model Content

The rotating rod is connected to the output end of the rotation drive assembly, and the lifting plate is connected to the output end of the lifting drive assembly. The lifting drive assembly is used to adjust the lifting plate to rise or fall, and the adjustment assembly is used to adjust the position of the rotating rod. During operation, the lifting plate descends, so that the suction cup body is in contact with the door and window. The negative pressure is generated by the negative pressure generating device, so that the air inside the suction cup body is transported to the negative pressure generating device through the pipeline assembly and then discharged. Then, the rotating drive assembly drives the rotating rod to rotate, thereby opening the door and window.

[0006] In a preferred embodiment of this technical solution, the lifting drive assembly includes a first motor fixedly mounted on the main mounting bracket and a first threaded rod fixedly connected to the first motor. The lifting plate is threadedly connected to the first threaded rod, and the first motor is used to drive the first threaded rod to rotate.

[0014] 2. The suction cup body adopts a snap-fit ​​design. With the dedicated snap-fit ​​component, the limit can be quickly released by simply rotating the adjustment screw in the corresponding area. There is no need to disassemble the mounting plate or pipeline components. The disassembly and replacement operation is extremely simple.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5 This utility model provides an embodiment of an electric opening device for aluminum alloy doors and windows, including a main mounting bracket 1, a lifting drive assembly mounted on the main mounting bracket 1, a lifting plate 21 slidably connected to the main mounting bracket 1, a negative pressure generating device body 22 and a rotation drive assembly mounted on the lifting plate 21, an adjustment assembly mounted on the lifting plate 21, a rotating rod 23 mounted on the adjustment assembly, a mounting plate 24 rotatably connected to the rotating rod 23, a suction cup body 25 and a snap-fit ​​assembly mounted on the mounting plate 24, and a pipeline assembly installed between the suction cup body 25 and the negative pressure generating device body 22. The rotating rod 23 is connected to the output end of the rotation drive assembly, and the lifting plate 21 is connected to the output end of the lifting drive assembly. The lifting drive assembly is used to adjust the lifting plate 21 to rise or fall, and the adjustment assembly is used to adjust the position of the rotating rod 23. When working, the lifting plate 21 is lowered so that the suction cup body 25 is in contact with the door and window. Then, the negative pressure is generated by the negative pressure generating device body 22, so that the air inside the suction cup body 25 is transported to the negative pressure generating device body 22 through the pipeline assembly and then discharged. Then, the rotating drive assembly drives the rotating rod 23 to rotate, thereby opening the door and window. Before using the device, adjust the distance between the rotating rods 23 according to the width specifications of the doors and windows, and ensure that the rotating rods 23 are compatible with the doors and windows. When using it, first start the lifting drive assembly to move the lifting plate 21 downward so that the suction cup body 25 is in contact with the surface of the aluminum alloy door and window to be opened. Then start the negative pressure generating device body 22. The air inside the suction cup body 25 is delivered to the negative pressure generating device body 22 through the pipeline assembly and then discharged, so that a negative pressure is formed inside the suction cup body 25, thereby firmly adsorbing the door and window. After the door and window are attracted and positioned, the rotation drive assembly is activated to drive the rotating rod 23 to rotate. The rotating rod 23 drives the mounting plate 24 and the door and window after attraction and fixation to rotate synchronously. As the rotating rod 23 rotates, the door and window are gradually opened until the required opening angle is reached. Then the rotation drive assembly can be closed to complete the door and window opening operation. The inside of the outer frame can be processed. After completion, the rotation drive assembly is reversed to drive the rotating rod 23 to rotate in the opposite direction and slowly drive the door and window to close. During the processing, if one of the four suction cup bodies 25 set on each set of mounting plates 24 is damaged or fails to adhere, the other suction cup bodies 25 can still maintain suction. After processing is completed, the clamping assembly can be adjusted to open and release the restriction of the corresponding suction cup body 25, thereby releasing the suction cup body 25 for replacement.

[0019] Please see Figure 1 - Figure 3 A further solution based on this embodiment is as follows: The adjustment assembly includes a first guide rod 210 fixedly mounted on the lifting plate 21, a bidirectional threaded rod 28 rotatably connected to the lifting plate 21, an adjustment knob 29 fixedly connected to the bidirectional threaded rod 28, and a sliding seat 217 slidably connected to the first guide rod 210. The sliding seat 217 is threadedly connected to the bidirectional threaded rod 28. The adjustment knob 29 is used to adjust the rotation of the bidirectional threaded rod 28. When the bidirectional threaded rod 28 rotates, it drives the sliding seat 217 to slide on the first guide rod 210. Rotating the adjustment knob 29 drives the bidirectional threaded rod 28 to rotate. The threaded rod is driven by the thread action. The sliding seat 217 slides along the first guide rod 210 in opposite directions to adjust the spacing. The first guide rod 210 provides stable guidance for the sliding seat 217, preventing deviation or jamming during sliding and ensuring adjustment accuracy. The bidirectional threaded rod 28 can simultaneously adjust the spacing between the two sliding seats 217. The adjustment operation is simple and convenient, requiring no complicated tools. It can be completed by rotating the adjustment knob 29, reducing the difficulty of operation and saving adjustment time. The adjustment range is flexible and controllable, and can adapt to aluminum alloy doors and windows of different widths, greatly improving the adaptability of the device to diverse processing needs and reducing equipment adjustment costs caused by differences in door and window widths.

[0020] Please see Figure 1 - Figure 2A further embodiment of this solution is as follows: the rotation drive assembly includes a second motor 211 fixedly mounted on the lifting plate 21, a rotating shaft 212 fixedly connected to the second motor 211, and a connecting sleeve 213 rotatably connected to the sliding seat 217. The connecting sleeve 213 is slidably connected to the rotating shaft 212, and the rotating rod 23 is fixedly connected to the connecting sleeve 213. The second motor 211 drives the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it drives the connecting sleeve 213 and the rotating rod 23 to rotate. The second motor 211 outputs... The output torque drives the rotating shaft 212 to rotate. The rotating shaft 212 transmits power to the connecting shaft sleeve 213 through cooperation with the connecting shaft sleeve 213, thereby driving the rotating rod 23 to rotate synchronously. The power transmission path is direct and the energy loss is small. It can efficiently convert the motor power into the rotational power of the rotating rod 23, improving the power performance of opening doors and windows. The sliding connection design between the connecting shaft sleeve 213 and the rotating shaft 212 does not affect the adjustment of the distance between the adjusting component and the sliding seat 217, realizing the compatibility and coordination of the adjustment function and the rotation function, and enhancing the rationality of the overall design of the device.

[0021] Please see Figure 3 A further solution based on this embodiment is as follows: a through groove adapted to the rotating shaft 212 is provided on the connecting sleeve 213. The connecting sleeve 213 is slidably connected to the rotating shaft 212 through the through groove. The through groove provides sliding space for the connecting sleeve 213 along the rotating shaft 212, which ensures that the rotating shaft 212 drives the connecting sleeve 213 to rotate synchronously, and also allows the connecting sleeve 213 to move laterally with the sliding seat 217. The adaptation design of the through groove and the rotating shaft 212 ensures that the continuity and stability of power transmission are not affected; the motion compatibility of the connecting sleeve 213 in both rotation and sliding dimensions is realized, ensuring the coordinated work of the adjustment component and the rotation drive component.

[0022] Please see Figure 1 - Figure 4 A further solution based on this embodiment is as follows: the pipeline assembly includes a fixed pipeline 214 fixedly installed on the rotating rod 23, a first connecting hose 215 fixedly connected between the fixed pipeline 214 and the negative pressure generating device body 22, and a second connecting hose 216 detachably installed between the fixed pipeline 214 and the suction cup body 25. The negative pressure generated by the negative pressure generating device is transmitted to the fixed pipeline 214 through the first connecting hose 215. The fixed pipeline 214 diverts the negative pressure to the second connecting hose 216, which ultimately acts on the suction cup body 25 to form an adsorption force. The fixed pipeline 214 plays a role in regulating the pipeline direction. The first and second connecting hoses 216 have good flexibility and can adapt to the positional changes during the rotation of the rotating rod 23 and the movement of the components, avoiding damage to the pipeline due to pulling or bending.

[0023] Please see Figure 5A further embodiment of this solution is as follows: the snap-fit ​​assembly includes a fixed base 31 fixedly mounted on the mounting plate 24, an adjusting screw 32 rotatably connected to the fixed base 31, a second guide rod 33 fixedly connected to the fixed base 31, a sliding bracket 34 slidably connected to the second guide rod 33, a linkage plate 35 fixedly connected to the sliding bracket 34, a sliding block 36 slidably connected to the fixed base 31, a connecting plate 37 fixedly connected to the sliding block 36, and a limiting block 38 fixedly connected to the connecting plate 37. The sliding bracket 34 is threadedly connected to the adjusting screw 32, and the limiting block 38 is snapped onto the suction cup body 25. The adjusting screw 32 is used to adjust the sliding bracket 34 to slide along the second guide rod 33. When the sliding bracket 34 slides, it drives the linkage plate 35 to rise or fall. When the linkage plate 35 moves, it drives the connecting plate 37 to open or close by working in conjunction with the sliding block 36. Working principle between components: The adjusting screw 32 drives the sliding bracket 34 to slide along the second guide rod 33. The sliding bracket 34 drives the linkage plate 35 to rise and fall. The linkage plate 35, through cooperation with the sliding block 36, pushes the sliding block 36 to move, thereby driving the connecting plate 37 and the limit block 38 to open and close. The coordinated linkage of multiple components realizes the precise opening and closing of the limit block 38, which can stably lock the suction cup body 25. The adjusting screw 32 has high transmission precision, and the second guide rod 33 ensures that the sliding bracket 34 slides smoothly, reducing jamming and ensuring the stability and reliability of the locking component. The operation is simple and convenient. The locking and unlocking actions can be completed by adjusting the screw 32 without complicated operation procedures.

[0024] Please see Figure 5 A further solution based on this embodiment is as follows: a sliding groove adapted to the linkage plate 35 is provided on the sliding block 36. The linkage plate 35 is slidably connected to the sliding groove and slides in the sliding groove. The sliding groove provides guidance and limit for the linkage plate 35, so that the lifting motion of the linkage plate 35 is converted into the horizontal movement of the sliding block 36. The matching design of the sliding groove and the linkage plate 35 plays a guiding role, ensuring that the linkage plate 35 and the sliding block 36 are accurately coordinated and the opening and closing action of the limit block 38 is accurate and controllable.

[0025] Working principle: Before using the device, it is necessary to make appropriate adjustments according to the width specifications of the door and window. Operate the adjustment knob 29 of the adjustment component to drive the bidirectional threaded rod 28 to rotate. The bidirectional threaded rod 28, through its cooperation with the sliding seat 217, drives the sliding seat 217 to slide in opposite directions along the first guide rod 210. When the sliding seat 217 moves, it drives the connecting bushing 213 to slide synchronously on the rotating shaft 212 through the through groove, thereby adjusting the distance between the rotating rods 23 to ensure that the rotating rods 23 are adapted to the width of the door and window. Once ready, the lifting drive assembly is activated. Its internal components drive the relevant transmission structure to move the lifting plate 21 downward. The lifting plate 21 moves the mounting plate 24 downward synchronously, so that the suction cup body 25 on the mounting plate 24 is in contact with the surface of the aluminum alloy door and window to be opened. Then, the negative pressure generating device body 22 is activated. The negative pressure generated by the negative pressure generating device body 22 is transmitted to the fixed pipe 214 through the first connecting hose 215 of the pipe assembly. The fixed pipe 214 diverts the negative pressure to the second connecting hose 216, which finally acts on the suction cup body 25, drawing out and expelling the air inside the suction cup body 25, so that a stable negative pressure is formed inside the suction cup body 25, thereby firmly adsorbing the door and window. After the door and window are attracted and positioned, the second motor 211 of the rotation drive assembly is started. The second motor 211 drives the rotating shaft 212 to rotate. The rotating shaft 212 cooperates with the connecting bushing 213 to transmit power to the connecting bushing 213, which in turn drives the rotating rod 23 to rotate. The rotating rod 23 drives the mounting plate 24 and the door and window after attraction and fixation to rotate synchronously. As the rotating rod 23 continues to rotate, the door and window are gradually opened until the opening angle required for processing is reached, and the door and window opening operation is completed. Then the interior of the door and window frame can be processed. After processing, the second motor 211 of the rotation drive assembly is started to reverse, driving the rotating shaft 212 to rotate in the opposite direction, which in turn drives the connecting bushing 213 and the rotating rod 23 to rotate in the opposite direction synchronously, thereby slowly driving the door and window to close. During this process, if any one of the four suction cup bodies 25 on each set of mounting plates 24 is damaged or falls off, the other suction cup bodies 25 can still provide continuous suction force to prevent the door and window from falling off. If it is necessary to replace the damaged or failed suction cup body 25, the adjusting screw 32 of the snap-fit ​​assembly can be operated to drive the sliding bracket 34 to slide in the opposite direction along the second guide rod 33. The sliding bracket 34 drives the linkage plate 35 to move in the opposite direction. The linkage plate 35 cooperates with the sliding block 36 through the sliding groove, driving the sliding block 36 to drive the connecting plate 37 and the limit block 38 to open, releasing the restriction on the corresponding suction cup body 25, so that the suction cup body 25 can be replaced. After the processing is completed, the second motor 211 drives the rotating shaft 212 to reverse, which in turn drives the rotating rod 23 to reverse and reset. After the negative pressure generating device body 22 is released from operation and the suction cup body 25 is released from adsorption, the first motor 26 drives the first threaded rod 27 to rotate, which drives the lifting plate 21 to rise, thus completing the door and window processing.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
