[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-6 This utility model provides an installation and positioning device for thermally broken aluminum windows and doors, comprising: a base plate 1, a main unit 5 fixedly connected to the upper surface of the base plate 1, a support leg 18 rotatably connected to the lower surface of the base plate 1, a brake mechanism provided inside the support leg 18, a roller 19 rotatably connected to the side surface of the support leg 18, a support plate 2 fixedly connected to the upper surface of the base plate 1, a push rod 13 fixedly connected to the rear surface of the support plate 2, a top plate 3 fixedly connected to the upper surface of the support plate 2, a positioning hole provided on the lower surface of the top plate 3, a motor 11 fixedly connected to the lower surface of the base plate 1, a lead screw 4 fixedly connected to the output end of the motor 11, the end of the lead screw 4 away from the motor 11 located inside the positioning hole, a lifting block 12 threadedly connected to the side surface of the lead screw 4, and a positioning seat 7 fixedly connected to the front surface of the lifting block 12.
[0025] Specifically, the base plate 1 serves as the fundamental support structure for the entire device, bearing the weight of all components above and providing a foundation for stable operation. The main unit 5, as the control core of the device, is responsible for coordinating and controlling the operation of various components, enabling automated operation. The outriggers 18 and rollers 19 work together to allow the device to be moved easily and flexibly to different working positions. The braking mechanism locks the rollers 19 through mechanical structures (such as friction plates and brakes), preventing them from rotating and fixing the device in the required position. The support plate 2 connects the base plate 1 and the top plate 3, providing support for the top... The plate 3 and positioning seat 7 provide support and also provide an installation position for the push rod 13, making it convenient for the operator to push the device and bring it close to the door or window where it needs to be installed. The top plate 3 is fixed to the upper surface of the support plate 2, and the positioning hole on the lower surface cooperates with one end of the lead screw 4, so that the lead screw 4 can rotate around its own axis. The output end of the motor 11 drives the lead screw 4 to rotate. According to the rotation direction and speed of the motor 11, the lifting block 12 is controlled to rise and fall, which in turn drives the positioning seat 7 fixed on its front surface to rise and fall, and positions the door or window placed on the positioning seat 7 at the correct height.
[0026] Reference Figure 1-6 The lower bottom wall of the positioning seat 7 is provided with a sliding groove 16, and a partition plate 17 is fixedly connected to the lower bottom wall of the sliding groove 16. The left surface of the positioning seat 7 is fixedly connected with a second motor 15, and the output end of the second motor 15 is fixedly connected with a second lead screw 14. The side surface of the second lead screw 14 is provided with a thread, which is located on the left and right sides of the second lead screw 14 and in opposite directions. The second lead screw 14 passes through the left surface of the positioning seat 7. The side surface of the second lead screw 14 is threadedly connected with a slider 8, and the right surface of the slider 8 is fixedly connected with a mounting plate 9. The second lead screw 14 and the slider 8 are located inside the sliding groove 16. The upper surface of the slider 8 is fixedly connected with a limit plate 10. The slider 8 and the limit plate 10 are located on the left and right sides of the second lead screw 14 and are both located in front of the support plate 2. The upper surfaces of the base plate 1 and the mounting plate 9 are fixedly connected with a reinforcing plate 6, which is located on both sides of the support plate 2 and the limit plate 10.
[0027] Specifically, the positioning seat 7 provides installation space for components such as the slider 8. Through internal components such as the sliding groove 16 and the lead screw 14, the horizontal movement adjustment of the limiting plate 10 is realized, thereby fixing and positioning the door and window in the horizontal direction. The output end of the motor 15 is fixedly connected to the lead screw 14. After being powered on, it drives the lead screw 14 to rotate. According to the rotation direction and speed of the motor 15, the movement direction and speed of the slider 8 are controlled. At the same time, since the left and right sides of its side surface are provided with threads in opposite directions, which are threadedly connected to the slider 8, when the motor 15 drives the lead screw 14 to rotate, the two sliders 8 will move in opposite or opposite directions along the axis of the lead screw 14 to fix the size of different doors and windows. The partition plate 17 divides the sliding groove 16 inside the positioning seat 7 into different areas, so that the two sliders 8 can move in their respective areas, ensuring the stability and accuracy of the movement of the sliders 8. The reinforcing plate 6 enhances the connection strength between the base plate 1 and the support plate 2, as well as between the slider 8 and the limiting plate 10.
[0028] Working principle: The base plate 1 provides basic support, and the main unit 5 is the control core for automation. The operator uses the push rod 13 and the support legs 18 and rollers 19 to move the device to the vicinity of the door and window installation location. The braking mechanism locks the rollers 19 to fix the device. The main unit 5 controls the operation of motor 11, and its output end drives the lead screw 4 to rotate in the positioning hole of the top plate 3. The lifting block 12 moves linearly along the axis of the lead screw 4, driving the positioning seat 7 to rise and fall, thus completing the door and window height positioning. At the same time, the main unit 5 starts motor 15, which drives the lead screw 14 to rotate. Because the threads on both sides of the lead screw 14 are opposite, under the action of the sliding groove 16 on the bottom wall of the positioning seat 7 and the partition plate 17, the two sliders 8 move towards or away from each other along the axis of the lead screw 14, causing the mounting plate 9 and the limiting plate 10 to move, thus achieving horizontal fixation and positioning of doors and windows of different sizes. In addition, the reinforcing plates 6 on the base plate 1 and the mounting plate 9 are located on both sides of the support plate 2 and the limiting plate 10 to enhance the connection strength and ensure the stable operation of the device, ultimately completing the door and window positioning and installation.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
