After production, doors and windows need to undergo performance testing to ensure they meet standards. Mechanical performance tests include opening and closing force, vertical load resistance, and static torsional resistance. Opening and closing force refers to the maximum values ​​of the locking and unlocking forces of the door / window locking device, and the opening and closing forces of the movable sash. For example, the door / window opening and closing force testing device with publication number CN201810970087.3 has a hook fixedly connected to the end of the side pull rope away from the lifting ring. This hook can hook onto the door / window handle, solving the problem that a single door / window opening and closing force testing device cannot test sliding and casement doors and windows, achieving the effect of testing the opening and closing force of both types of doors and windows with a single device.

[0036] Example 3

[0037] Reference Figure 6 and Figure 7 This is the third embodiment of the present invention, which differs from the previous two embodiments in that...

[0038] In this embodiment, preferably, the upper clamping plate 12 and the lower clamping plate 13 are respectively arranged opposite to each other at the upper and lower ends of the support frame 11. A clamping rod is screwed onto the two clamping plates. When the door and window are located between the two clamping plates, the clamping rod is rotated to clamp and fix the door and window. A driving component 3 is provided between the lower end of the support frame 11 and the lower clamping plate 13. The driving component 3 can drive the lower clamping plate 13 to move upward. The fixing range between the two clamping plates can be adjusted according to the size of the door and window. The driving component 3 includes an adjusting cylinder 31, which is vertically installed on the left side of the support frame 11. An installation plate 32 is provided between the end of the extension rod provided inside the adjusting cylinder 31 and the left end of the lower clamping plate 13. The right side of the support frame 11... The inner side of the end is provided with a guide groove 34, and the right side surface of the upright frame 11 is provided with a through hole 35 that passes through the guide groove 34. The right end of the lower clamping plate 13 is provided with a slider that slides in cooperation with the guide groove 34. A limit bolt 33 is installed in one of the through holes 35. The limit bolt 33 is threadedly connected to the through hole 35. The limit bolt 33 cooperates with the through holes 35 at different heights to limit the slider at different height positions. When the lower clamping plate 13 moves with the extension rod in the adjusting cylinder 31, it drives the slider to move in the guide groove 34. When the height of the lower clamping plate 13 is fixed, the limit bolt 33 is rotated so that its inner end presses and fixes the slider, increasing the stability of the lower clamping plate 13 in use.

[0039] The working principle and usage process of this invention: When using this invention, for casement windows, two casement windows can be placed between the upper clamping plate 12 and the lower clamping plate 13, with the two casement window bodies rotating in opposite directions. Based on the height of the casement window bodies, the piston rod inside the second drive cylinder 221 extends, causing the connecting plate 223 to move along with the piston rod. Because the platform plate 26 is limited by the guide block and slide groove between it and the support frame 11, the platform plate 26 moves along the support frame 11 in the Y-axis direction. The support plate 222 and the second drive cylinder 221 adapt to the rotation of the platform plate 26, and the height of the rotating plate 27 and the connecting member 23 changes accordingly. When the height is appropriate, the second drive cylinder 221 stops working, and the first drive cylinder... When mechanism 232 is activated, the internal piston rod extends, driving the stabilizing plate 234 and vacuum suction cup 231 towards the window. Once the vacuum suction cup 231 contacts the window surface, the external air extraction device activates, sucking away the air between the vacuum suction cup 231 and the window through the extraction pipe 235, creating a vacuum negative pressure state and achieving a tight connection. The first motor 241 activates, causing the worm gear 242 to rotate with the output shaft at the end of the first motor 241. The two worms 243 rotate synchronously with the worm gear 242, driving the winding wheel 244 on it to rotate. As the overall length of the pull strap 246 decreases with winding, it drives the rotating plate 27 to rotate. The two windows rotate in opposite directions and open as the rotating plate 27 and connecting component 23 rotate. As the movable plate 27 rotates, the arc-shaped rod 6 moves accordingly. The arc-shaped rod 6 rotates at the same angle as the rotating plate 27, and the return spring 4 is compressed. When the window rotates to the set position, the air extraction pipe 235 delivers air to balance the air pressure between the vacuum suction cup 231 and the window with the external pressure. The vacuum suction cup 231 separates from the window and continues to move outward with the pull strap 246 and the rotating plate 27 until it reaches a suitable position on the outside of the window. The first motor 241 stops working, while the window continues to move outward a certain distance under the inertia of the external force after it is removed. At this time, the vacuum suction cup 231 does not affect the window after the inertial movement. It can measure the difference and angle change between the set position and the inertial movement position. After measurement, the first motor 241 reverses. The rotation causes the winding wheel 244 to rotate in the opposite direction, releasing the pull strap 246. Under the return force of the return spring 4, the rotating plate 27 moves backward, and the vacuum suction cup 231 contacts the window, pushing it back. Under the action of the first drive cylinder 232, the window closes. The force sensor located in the lower clamping plate 13 detects the force received when in contact with the window. By analyzing the difference in force received when the window closes multiple times, the performance of the window closing force can be detected. The above operation is repeated throughout the process, and the differences in inertial movement when the window is rotated open multiple times are compared. At the same time, the data measured when the window is pushed back to close multiple times are analyzed, which can detect the opening and closing force of the casement window. Two measurements can be taken simultaneously, improving measurement efficiency.

[0040] For testing the opening and closing force of sliding windows, two sliding windows can be measured simultaneously. When the vacuum suction cup 231 is attached to the window body, the second motor 252 works, driving the lead screw 253 to rotate in place. The base plate 21, which is threaded to the lead screw 253, moves to the right along the guide rod 254, causing the connecting component 23 and the sliding window panel to move to the right and open. When the sliding window panel moves to the set position, the vacuum suction cup 231 is separated from the sliding window panel. The sliding window panel moves outward under inertia to see if it reaches the window frame. Similarly, the second motor 252 can be reversed, causing the base plate 21 to move to the left, driving the connecting component 23 and the sliding window panel to move to the left to the set position, and then observing whether they move to the window frame under inertia. If the difference in the position of the sliding window panel is measured multiple times under a certain force, the opening and closing performance of the sliding window panel can be analyzed.
