Description

Technical Field

[0001] This utility model belongs to the field of materials testing technology, specifically relating to a device for testing the impact resistance of architectural glass. Background Technology

[0002] Architectural glass is a material used in the construction field. It has advantages such as light transmission, sound insulation, heat insulation, and wear resistance. In order to protect the safety of people and prevent glass breakage from causing damage to the surrounding environment, glass is required to have a certain impact resistance. Existing technology usually uses the falling ball method to test the impact resistance of architectural glass. During the test, a metal ball needs to be placed at a certain height and allowed to fall freely to impact the glass under test, and then observe whether the glass is damaged.

[0003] Chinese patent CN221377520U discloses a tempered glass impact resistance testing device. The solution includes a tempered glass support platform, an impact testing device, and a movable protective device. The tempered glass support platform includes a bottom support, which includes a rectangular frame. The impact testing device includes a falling ball detection mechanism, which includes a steel ball and an electromagnetic adsorption mechanism. The above solution uses the electromagnetic adsorption mechanism to adsorb the steel ball, and then releases the steel ball by de-energizing the electromagnetic adsorption mechanism, allowing the steel ball to fall freely and impact the glass, thereby testing the impact resistance of the glass.

[0004] According to the requirements of relevant testing standards, multiple glass samples need to be tested in actual testing. When using the above solution, the testing personnel need to pick up the falling steel balls multiple times and place them at the bottom of the electromagnetic adsorption mechanism for adsorption. However, the steel balls are relatively heavy, and this step is a waste of human resources and affects the testing efficiency. Utility Model Content

[0005] The present invention aims to provide a device for testing the impact resistance of architectural glass, so as to solve the problem of the above-mentioned solutions being wasteful of human resources.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An impact resistance testing device for architectural glass includes a testing box, a top cover, a movable plate, a drive mechanism, and a steel ball. The testing box has an open top and two horizontal bars are movably arranged inside. Support frames are symmetrically arranged at the bottom of the two horizontal bars on their respective sides. The top cover is fixedly installed on the top of the testing box and has a through hole. A vertical tube is fixedly installed on the top of the top cover, and a through groove is provided on the side of the vertical tube near the through hole. An mounting plate is fixedly installed on one side of the top of the vertical tube above the through hole. The movable plate slides through the through groove, and a ring-shaped magnet is fixedly installed at one end of the movable plate above the through hole. A vertical bar passes through the mounting plate above the magnet. The drive mechanism is located inside the vertical tube and is used to drive the movable plate to move up and down. The steel ball can be magnetically attracted to the bottom of the magnet.

[0008] The principle and effects of this technical solution:

[0009] Initially, the steel ball is magnetically attracted to the bottom of the magnet, and the movable plate is in a low position. During testing, the glass to be tested is placed on the two support frames. Then, the drive mechanism moves the movable plate upward, causing the magnet and steel ball to move upward. When the magnet passes through the vertical rod, the vertical rod prevents the steel ball from moving upward further. When the weight of the steel ball is greater than the magnetic force between the magnet and the steel ball, the steel ball falls freely downward and impacts the glass to be tested. Then, the drive mechanism moves the movable plate downward, and the magnet gradually approaches the steel ball. When the weight of the steel ball is less than the magnetic force between the magnet and the steel ball, the steel ball is magnetically attracted to the bottom of the magnet again. At this point, the glass to be tested after being impacted by the steel ball is removed and inspected. Then, the next glass to be tested is placed on the support frame, and the drive mechanism moves the movable plate upward again. The above steps are repeated to test multiple glass samples.

[0010] With the above setup, the moving plate is moved up and down by the drive mechanism. When the glass under test is not damaged or only cracked after being impacted by the steel ball, the magnet automatically attracts the steel ball that has fallen to the top of the glass. This allows the tester to manually move the steel ball that has penetrated the glass, reducing the number of times the tester has to manually move the steel ball, saving manpower and improving the test efficiency.

[0011] In this utility model, a bidirectional screw is rotatably installed on one side of the through hole inside the detection box, and a guide rod is fixedly installed on the other side of the through hole inside the detection box. One end of the two crossbars is symmetrically fitted onto the positive and negative thread sections of the bidirectional screw, and the other end of the two crossbars is slidably fitted onto the guide rod. A first motor that is driven and connected to the bidirectional screw is fixedly installed on the outer wall of the detection box.

[0012] The principle and effects of this technical solution:

[0013] The first motor drives the bidirectional screw to rotate. Because the guide rod prevents the crossbar from rotating, the two crossbars move closer to or further away from each other as the bidirectional screw rotates.

[0014] The above setup allows for the movement of the two crossbars, thereby supporting glass samples of different sizes.

[0015] In this utility model, the driving mechanism includes a threaded rod that is rotatably disposed in the vertical tube, and a second motor that is fixedly disposed at the top of the vertical tube and is connected to the threaded rod for transmission. The movable plate extends into the vertical tube and is fitted onto the threaded rod, and the side wall of the movable plate slides against the inner side wall of the through groove.

[0016] The principle and effects of this technical solution:

[0017] The second motor drives the threaded rod to rotate. Because the through groove prevents the movable plate from rotating, the movable plate moves up and down with the rotation of the threaded rod.

[0018] The above settings achieve the purpose of moving the movable lever up and down.

[0019] In this invention, the mounting plate has a through screw hole above the through hole, and the outer wall of the vertical rod has external threads. The vertical rod is threaded into the screw hole. With this configuration, the height of the bottom of the vertical rod can be adjusted by rotating it, thereby adjusting the falling height of the steel ball and improving the applicability of the device.

[0020] In this invention, a sleeve is fixedly installed inside the through hole. The height difference between the lower edge of the sleeve and the support frame is h, and the radius of the steel ball is r, with h being less than r. This design prevents the steel ball from falling onto the glass under test and moving outside the through hole, thus avoiding situations where the magnet cannot attract the steel ball.

[0021] In this invention, three top rods are fixedly arranged at circumferential intervals at the bottom of the vertical rod. This arrangement prevents the steel ball from rotating in a direction perpendicular to the axis of the vertical rod during the process of the vertical rod pushing the steel ball away from the magnet, thus ensuring that the center of gravity of the steel ball is aligned with the axis of the through hole when it falls.

[0022] In this invention, the side wall of the testing box has an opening, and a baffle is hinged to the opening. This design facilitates the placement of the glass plate by the operator and prevents glass fragments from scattering out of the testing box when a steel ball impacts the glass under test, thus improving the safety of the device during use.

[0028] Example:

[0029] As attached Figure 1-3 As shown, this utility model discloses an impact resistance testing device for architectural glass, including a testing box 10, a top cover 30, a movable plate 40, a drive mechanism, and a steel ball 50. The testing box 10 has an open top, and two crossbars 20 are movably arranged inside the testing box 10. Support frames 21 are symmetrically arranged at the bottom of the two crossbars 20 on the side close to each other. The top cover 30 is fixedly installed on the top of the testing box 10, and a through hole 31 is opened on the top of the top cover 30. A vertical tube 3 is fixedly installed on the top of the top cover 30. 2. A through groove 33 is provided on the side of the vertical tube 32 near the through hole 31. An mounting plate 34 is fixedly provided on the top side of the vertical tube 32 above the through hole 31. The movable plate 40 slides through the through groove 33. A ring-shaped magnet 41 is fixedly provided on one end of the movable plate 40 above the through hole 31. A vertical rod 35 is provided on the mounting plate 34 above the magnet 41. The driving mechanism is provided inside the vertical tube 32 to drive the movable plate 40 to move up and down. The steel ball 50 can be magnetically attracted to the bottom of the magnet 41.

[0030] In this embodiment, a bidirectional screw 11 is rotatably disposed inside the detection box 10 on one side of the through hole 31, and a guide rod 12 is fixedly disposed inside the detection box 10 on the other side of the through hole 31. One end of the two crossbars 20 is symmetrically fitted onto the positive and negative threaded sections of the bidirectional screw 11, and the other end of the two crossbars 20 is slidably fitted onto the guide rod 12. A first motor 13, which is connected to the bidirectional screw 11, is fixedly disposed on the outer wall of the detection box 10.

[0031] In this embodiment, the driving mechanism includes a threaded rod 61 that is rotatably disposed in the vertical tube 32, and a second motor 62 that is fixedly disposed at the top of the vertical tube 32 and is connected to the threaded rod 61 for transmission. The movable plate 40 extends into the vertical tube 32 and is fitted onto the threaded rod 61, and the side wall of the movable plate 40 slides against the inner side wall of the through groove 33.

[0032] In this embodiment, the mounting plate 34 has a through screw hole 341 above the through hole 31, and the outer side wall of the vertical rod 35 has external threads, and the vertical rod 35 is threaded into the screw hole 341.

[0033] In this embodiment, a sleeve 36 is fixedly installed inside the through hole 31. The height difference between the lower edge of the sleeve 36 and the support frame 21 is h, and the radius of the steel ball 50 is r, which is set to be less than r.

[0034] In this embodiment, three top rods 351 are fixedly provided at circumferential intervals at the bottom of the vertical rod 35.

[0035] In this embodiment, the side wall of the detection box 10 is provided with an opening 14, and a baffle 15 is hinged at the opening 14.

[0036] The through hole 31, screw hole 341 and magnet 41 are coaxial.

[0037] The specific implementation process is as follows:

[0038] Initially, the steel ball 50 is magnetically attracted to the bottom of the magnet 41, and the movable plate 40 is in a low position. During testing, the glass to be tested 100 is placed on the two support frames 21. Then, the drive mechanism moves the movable plate 40 upward, causing the magnet 41 and the steel ball 50 to move upward. When the magnet 41 passes through the vertical rod 35, the vertical rod 35 prevents the steel ball 50 from moving upward further. When the weight of the steel ball 50 is greater than the magnetic force between the magnet 41 and the steel ball 50, the steel ball 50 falls freely downward and impacts the glass to be tested. Glass 100 is then moved down by the drive mechanism, and the movable plate 40 is lowered. Magnet 41 gradually approaches steel ball 50. When the weight of steel ball 50 is less than the magnetic force between magnet 41 and steel ball 50, steel ball 50 is magnetically attracted to the bottom of magnet 41 again. At this time, the glass 100 to be tested after being impacted by steel ball 50 is taken out and inspected. Then the next glass 100 to be tested is placed on support frame 21, and the drive mechanism is moved up by the movable plate 40 again. The above steps are repeated to test multiple glass 100 samples.

[0039] The first motor 13 drives the bidirectional screw 11 to rotate. Because the guide rod 12 prevents the crossbar 20 from rotating, the two crossbars 20 move closer or further apart as the bidirectional screw 11 rotates.

[0040] The second motor 62 drives the threaded rod 61 to rotate. Because the through groove 33 prevents the movable plate 40 from rotating, the movable plate 40 moves up and down with the rotation of the threaded rod 61.

[0041] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
