Description

Technical Field

[0001] This utility model relates to the field of door and window strength testing technology, specifically a building door and window impact resistance testing device. Background Technology

[0002] The production process of doors and windows requires random inspections of their quality. According to national standards, the required tests include air tightness, water tightness, and wind pressure resistance. These three properties are the most important performance indicators for the quality of windows. For windows used in engineering projects, these three properties are mandatory tests. Therefore, a test report on the three properties of windows is generally required for project acceptance.

[0003] When submitting doors and windows for inspection, three pieces are usually submitted. However, existing testing methods typically only test fixed windows, and only one door or window can be tested at a time, resulting in low testing efficiency. Furthermore, it is impossible to test the impact of windows that are suddenly damaged by severe weather on other windows.

[0004] In general, glass doors and windows are tested by impact or pressure to determine whether their sturdiness meets the requirements for daily use. However, when testing them with impact blocks of different weights, repeated disassembly and reassembly are required, which is not only cumbersome but also time-consuming and labor-intensive, reducing testing efficiency. Therefore, there is a need for a building door and window impact resistance testing device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building door and window impact resistance detection device, including a protective box, a placement box is installed through the front side of the protective box, a connecting cover is snapped onto the upper part of the protective box, a limiting tube is installed through the upper part of the connecting cover, an impact box is movably installed inside the limiting tube, and two sets of strong magnetic blocks are symmetrically installed on the outside of the impact box.

[0007] A mounting plate is attached to the rear side of the protective box. An L-shaped plate is movably mounted on the upper part of the mounting plate. A central cavity is opened through the center of the upper surface of the L-shaped plate. A set of electric drive seats is installed on the front and rear sides of the upper surface of the L-shaped plate at the central cavity. A set of movable plates is slidably mounted on the upper part of each set of electric drive seats. A set of arc-shaped plates is movably mounted on the corresponding sides of the two sets of movable plates. Several sets of weights are clamped between the two sets of arc-shaped plates.

[0008] Two sets of winding motors are symmetrically installed on the rear side of the mounting plate. Each set of winding motors has a winding pull rope inside. An electromagnet is locked at the end of each set of pull ropes.

[0009] Preferably, an impact-resistant rubber pad is attached to the bottom of the protective box, the protective box limiting tube is installed at the center of the box, and two sets of limiting grooves are symmetrically opened on the outer arc surface of the limiting tube.

[0010] Preferably, several sets of electric push rods are equidistantly installed in the middle of the mounting plate, and the telescopic top end of each set of electric push rods is bolted to the bottom end of the L-shaped plate.

[0011] Preferably, the impact box is provided with several sets of limiting rods inside, and two sets of positioning rods are symmetrically installed on the outer arc surface of the impact box. Each set of strong magnetic blocks is installed inside the positioning rod, and the positioning rod is slidably installed inside the limiting groove.

[0012] Preferably, the upper surface of the L-shaped plate has two sets of side holes connected on both sides of the central cavity, and two sets of positioning frames are symmetrically installed on the upper surface of the L-shaped plate.

Two sets of limiting plates are fixedly installed on both sides of the slider corresponding to the side groove positions, and the two sets of arc-shaped plates are respectively installed on the outer end of one set of sliders.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Two sets of electrically driven seats control the movement of the moving plates, allowing the curved plates to clamp or release the weights. After the impact box is pulled upward by the pull rope to fully assemble all the weights, the two sets of curved plates move outward to release the weights, allowing each set of weights to fully enter the impact box.

By continuously raising and lowering the pull rope, the impact box is repeatedly raised and lowered, and the number of weights is continuously changed to complete the impact strength test of doors and windows under different weights, greatly improving the overall safety and convenience of the device.

[0025] 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.

[0026] This utility model provides: a building door and window impact resistance detection device, such as Figures 1-7 As shown, it includes a protective box 1, a placement box 3 is installed through the front of the protective box 1, a connecting cover 6 is snapped onto the upper part of the protective box 1, a limit tube 7 is installed through the upper part of the connecting cover 6, an impact box 11 is movably installed inside the limit tube 7, and two sets of strong magnetic blocks 14 are symmetrically installed on the outside of the impact box 11.

[0027] A mounting plate 4 is attached to the rear side of the protective box 1. An L-shaped plate 15 is movably mounted on the upper part of the mounting plate 4. A central cavity 16 is opened through the center of the upper surface of the L-shaped plate 15. A set of electric drive seats 21 are respectively installed on the front and rear sides of the central cavity 16 on the upper surface of the L-shaped plate 15. A set of movable plates 22 is slidably mounted on the upper part of each set of electric drive seats 21. A set of arc plates 29 are movably mounted on the corresponding sides of the two sets of movable plates 22. Several sets of weights 30 are clamped between the two sets of arc plates 29.

[0028] Two sets of winding motors 9 are symmetrically installed on the rear side of the mounting plate 4. Each set of winding motors 9 has a winding pull rope 10 inside. An electromagnet 31 is locked at the end of each set of pull ropes 10. The two sets of pull ropes 10 extend symmetrically from the upper surface of the L-shaped plate 15, and the electromagnet 31 is attracted to the corresponding strong magnetic block 14.

[0029] Preferably, the bottom of the protective box 1 is fitted with an impact-resistant rubber pad 2, and the limiting tube 7 of the protective box 1 is installed at the center of the placement box 3. The outer arc surface of the limiting tube 7 is symmetrically provided with two sets of limiting grooves 8. The impact-resistant rubber pad 2 installed at the bottom of the protective box 1 reduces the damage to the protective box 1 and the bottom surface when the impact box 11 impacts downward, improving the overall safety of the device. The placement box 3, which is slidably installed inside the protective box 1, can store doors and windows and avoid the danger caused by damage to doors and windows after impact. At the same time, the connecting cover 6 is provided to cover the upper part of the protective box 1. In addition, the limiting tube 7 installed through the center of the connecting cover 6 restricts the position of the impact box 11, so that the impact box 11 can stably impact the door and window, further improving the stability of the strength test.

[0030] Furthermore, several sets of electric push rods 5 are equidistantly installed in the middle of the mounting plate 4. The telescopic top of each set of electric push rods 5 is bolted to the bottom of the L-shaped plate 15. The mounting plate 4 limits the electric push rods 5 and the winding motor 9. The electric push rods 5 can adjust the working height of the L-shaped plate 15 to adjust the impact intensity, while the winding motor 9 winds up the pull rope 10 to ensure that the electromagnet 31 at the end of the pull rope 10 can stably attract the impact box 11, thereby completing the control of the working height of the impact box 11.

[0031] Furthermore, the impact box 11 is equipped with several sets of limiting rods 12 inside, and two sets of positioning rods 13 are symmetrically installed on the outer arc surface of the impact box 11. Each set of strong magnetic blocks 14 is installed inside the positioning rod 13, and the positioning rod 13 is slidably installed inside the limiting groove 8. The limiting rods 12 installed inside the pulling rope 10 limit the weight 30 to prevent the weight 30 from flying out during the impact. In addition, the positioning rods 13 installed on the outer arc surface of the impact box 11 cooperate with the limiting groove 8 to improve the stability of the impact box 11 when falling. The strong magnetic blocks 14 installed in the middle of the positioning rods 13 can cooperate with the electromagnet 31 to raise and reset the impact box 11 after one impact.

[0032] It is worth noting that two sets of side holes 17 are connected on both sides of the central cavity 16 on the upper surface of the L-shaped plate 15. Two sets of positioning frames 18 are symmetrically installed on the upper surface of the L-shaped plate 15, and two sets of rotating shafts 19 are symmetrically installed inside each positioning frame 18. The pull rope 10 is guided by the two sets of rotating shafts 19 to make the electromagnet 31 extend out from the side holes 17. The central cavity 16 on the upper surface of the L-shaped plate 15 can ensure that the impact box 11 is fully raised and clamped to all the weights 30 on the upper part of the L-shaped plate 15. The side holes 17 on both sides of the central cavity 16 limit the movement of the positioning rod 13 to prevent the L-shaped plate 15 from blocking the electromagnet 31. The two sets of positioning frames 18 installed on the upper surface of the L-shaped plate 15 limit the rotating shafts 19. The rotating shafts 19 complete the turning of the pull rope 10, so that the pull rope 10 can be vertically raised and lowered in accordance with the side holes 17, thereby better ensuring that the electromagnet 31 is docked with the strong magnetic block 14.

[0033] Specifically, two sets of limiting grooves 20 are symmetrically opened on the upper surface of the L-shaped plate 15 at the front and rear sides of the central cavity 16. Each set of electric drive seats 21 is inserted into the limiting groove 20. A set of electric slides 23 is bolted to the corresponding sides of the two sets of moving plates 22. Several sets of rotating wheels 24 are rotatably installed inside each set of electric slides 23. Two sets of side grooves 25 are symmetrically opened on the inner side of the electric slides 23. The two sets of limiting grooves 20 opened on the upper surface of the L-shaped plate 15 limit the electric drive seats 21. A ball screw is installed inside the electric drive seats 21 to control the movement of the moving plates 22, thereby contacting the clamping of the counterweight 30.

[0034] In addition, a slider 26 is slidably installed inside the electric slide table 23. The slider 26 has a sliding groove 28 corresponding to the installation position of the rotating wheel 24. Two sets of limiting plates 27 are fixedly installed on both sides of the slider 26 corresponding to the side grooves 25. Two sets of arc plates 29 are respectively installed on the outer end of one set of sliders 26. The electric slide table 23 controls the rotation of the rotating wheel 24. The rotation of the rotating wheel 24 changes the working height of the slider 26. After each set of weights 30 has completely entered the impact box 11, the number of weights 30 inside the impact box 11 is adjusted by adjusting the working height of the arc plates 29, which further improves the control of the overall weight of the impact box 11 so that the device can better complete multiple collision tests.

[0035] 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.
