Specific embodiments

[0044] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0045] Please refer to Figures 1-3 , the present utility model provides the following technical solutions: A window and door anti-fall strength testing device includes an equipment base 1, and a first vertical plate 2 and a second vertical plate 3 are respectively fixed at both ends of the top surface of the equipment base 1. It further includes: a movable mounting plate 4, a tension sensor 5, a movable test plate 6, a connecting mechanism 7, a first adjusting mechanism 75, a second adjusting mechanism 76, and a hydraulic cylinder 8.

[0046] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the movable mounting plate 4 is movably mounted on the top surface of the equipment base 1, and a fixing cavity 41 for mounting the window frame is machined on the movable mounting plate 4. The tension sensor 5 is fixed between the first vertical plate 2 and the movable mounting plate 4. The movable test plate 6 is movably mounted on the top surface of the equipment base 1, and a sliding cavity 61 is machined on the movable test plate 6. The connecting mechanism 7 includes two moving platforms 71 movably mounted in the sliding cavity 61, two moving blocks 72 movably mounted on the moving platforms 71, a connecting rope 73, and a fixing clip 74. The connecting rope 73 is fixed to the moving block 72, and the fixing clip 74 is fixed to one end of the connecting rope 73 away from the moving block 72 for connecting the window frame. The first adjusting mechanism 75 is drivingly connected to the two moving platforms 71 for adjusting the distance between the two moving platforms 71. The second adjusting mechanism 76 is drivingly connected to the two moving blocks 72 for adjusting the distance between the two moving blocks 72. The hydraulic cylinder 8 is fixed on the second vertical plate 3, and the piston rod of the hydraulic cylinder 8 passes through the second vertical plate 3 and is fixedly connected to the movable test plate 6. After adopting the above scheme, during use, the window frame is fixed in the fixing cavity 41, for example, the window frame is fixed in the fixing cavity 41 using bolts. Then, the hydraulic cylinder 8 is started to finely adjust the position of the movable test plate 6 to make the movable test plate 6 approach the window frame. Then, all the fixing clips 74 are connected to the window frame. Finally, the hydraulic cylinder 8 is started to make the movable test plate 6 move away from the movable mounting plate 4. The movable test plate 6 pulls the window frame through the connecting mechanism 7, and the window frame pulls the tension sensor 5 using the movable mounting plate 4. The tension sensor 5 can accurately reflect the tension received by the window frame. Gradually increase the tension of the hydraulic cylinder 8 until the tension sensor 5 reaches the standard value (the specified value that meets the usage requirements), which indicates that the current installation method meets the requirements. If the window frame becomes loose or falls during this period, it means that the current installation method does not meet the requirements and the fixing method of the window frame needs to be changed. At this time, the tester changes the fixing method of the window frame and then uses the same method as above to test the window frames with different installation methods again. In addition, during the test, the first adjusting mechanism 75 can also be started to adjust the distance between the two moving platforms 71, or the second adjusting mechanism 76 can be started to adjust the distance between the two moving blocks 72 to make the fixing clips 74 connect different positions of the window frame for multiple tests to form a control group, greatly improving the test accuracy.

The C-shaped clamp 741 is fixed to one end of the connecting rope 73 away from the moving block 72. The clamping plate 742 is located inside the C-shaped clamp 741. The adjusting screw 743 is installed on the C-shaped clamp 741 by means of screw thread engagement, and the end of the adjusting screw 743 is rotatably connected to the clamping plate 742 by means of a bearing. After adopting the above scheme, during use, the C-shaped clamp 741 is used to fasten the window frame, and then the adjusting screw 743 is rotated, so that the adjusting screw 743 pushes the clamping plate 742 to move under the action of screw thread engagement, and the clamping plate 742 is used in cooperation with the C-shaped clamp 741 to clamp the window frame, ensuring the stability of the connection and being applicable to window frames with different thicknesses.

After adopting the above scheme, when the movable test plate 6 moves, it will drive the second slider 12 to move along the second guide rail 11, improving the stability of the movable test plate 6.

[0054] It should be noted that the tension sensor 5, the first servo motor 752, the second servo motor 763, and the hydraulic cylinder 8 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to the usage needs. Their working principles are common knowledge well-known to those skilled in the art and have been fully disclosed in the prior art, so no further elaboration will be provided herein.

[0055] The circuit connection involved in the present utility model is a conventional means adopted by those skilled in the art and can obtain technical inspiration through a limited number of tests, belonging to the widely used prior art.

[0056] The components not described in detail in this article are prior art.

[0057] Working principle and usage process of the present utility model: When using the test equipment of the present utility model, fix the window frame in the fixed cavity 41, for example, use bolts to fix the window frame in the fixed cavity 41, and then start the hydraulic cylinder 8 to finely adjust the position of the movable test plate 6 to make the movable test plate 6 approach the window frame;

[0058] Then connect all the fixed clamps 74 to the window frame. First, use the C-shaped clamp 741 to fasten the window frame, and then rotate the adjusting screw 743. Under the action of thread engagement, the adjusting screw 743 pushes the clamping plate 742 to move, and the clamping plate 742 cooperates with the C-shaped clamp 741 to clamp the window frame, ensuring the stability of the connection and being applicable to window frames with different thicknesses;

[0059] Finally, start the hydraulic cylinder 8 to make the movable test plate 6 move away from the movable mounting plate 4. The movable test plate 6 pulls the window frame through the connecting mechanism 7, and the window frame pulls the tensile force sensor 5 through the movable mounting plate 4. The tensile force sensor 5 can accurately reflect the tensile force received by the window frame;

[0060] Gradually increase the tensile force of the hydraulic cylinder 8 until the tensile force sensor 5 reaches the standard value (the specified value that meets the usage requirements), which indicates that the current installation method meets the requirements. If the window frame becomes loose or falls during this period, it means that the current installation method does not meet the requirements and the fixing method of the window frame needs to be changed. At this time, the tester changes the fixing method of the window frame and then uses the same method as above to test the window frames with different installation methods again;

[0061] In addition, during the test, the distance between the two moving platforms 71 can be adjusted by starting the first adjustment mechanism 75, or the distance between the two moving blocks 72 can be adjusted by starting the second adjustment mechanism 76, so as to connect the fixed clamps 74 to different positions of the window frame for multiple tests to form a control group, greatly improving the test accuracy.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
