Description

Technical Field

[0001] The utility model relates to the technical field of impact resistance detection, in particular to a toughened glass impact resistance detection device. Background Art

[0002] Tempered glass (also known as reinforced glass) is a type of safety glass. Tempered glass is actually a prestressed glass. To increase its strength, compressive stress is typically created on the glass surface through chemical or physical methods. When the glass is subjected to external forces, this stress is first offset by the surface stress, thereby increasing its load-bearing capacity and enhancing its resistance to wind pressure, cold and heat, and impact. It is important to distinguish it from fiberglass reinforced plastic (FRP).

[0003] However, the existing tempered glass impact testing equipment mostly refers to surface-mounted strain gauges. The installation process of the strain gauge is relatively complicated, and the user needs to use the base glue and the mounting base to fit it on the ground, which is inconvenient for debugging and installing the strain gauge, and increases the installation time and labor cost. In addition, welding may be required during the installation and disassembly process, which is more likely to damage the strain gauge and increase the detection cost of the strain gauge. In addition, connecting the base glue and the mounting base can easily affect the final detection accuracy of the strain gauge. Therefore, it is necessary to propose a new type of tempered glass impact testing equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the problems that the installation process of the strain gauge is complicated, which increases the installation time and labor cost, the welding process may damage the strain gauge, and the uneven thickness of the connecting base glue easily affects the accuracy of the measurement results. A tempered glass impact resistance detection device is proposed.

[0006] Preferably, a proximity switch is installed on one side of the surface wall of the connecting seat, and a working groove is opened on one side of the bottom wall of the box.

[0007] Preferably, two bellows are fastened to one side of the bottom wall of the box body, and fans are installed on one side of the inner walls of the two bellows.

[0008] Preferably, a handle is fastened to one side of the top wall of the box body, and an induction light is installed on one side of the top wall of the box body.

[0009] Preferably, a maintenance door is hinged on one side of the surface wall of the box body, and three guide rails are fastened to one side of the surface wall of the box body.

[0010] Preferably, a protective cover is slidably connected to one side of the surface wall of the three guide rails, and a support plate is slidably connected to one side of the bottom wall of the box.

[0011] Preferably, the support plate and the protective cover are movably connected, and four support columns are fastened to one side of the bottom wall of the box.

[0024] In this embodiment, the user starts the motor 2 installed inside the working box. Under the action of the motor 2, the output end of the motor 2 rotates to drive the worm 3 to rotate, and the two brackets 4 support the worm 3. The rotation of the worm 3 drives the worm wheel 5 to rotate, and the rotation of the worm wheel 5 drives the screw rod 6 to descend. The descent of the screw rod 6 drives the connecting seat 9 to descend, and the descent of the connecting seat 9 drives the strain gauge 10 to descend. The slide bar 7 plays a role of balancing the descent. Under the action of the working groove 12, the connecting seat 9 descends and leaves the box body 1. The proximity switch 11 controls the motor 2 through the PLC. When the proximity switch 11 touches the ground, the motor 2 is stopped, thereby reducing the installation time and labor cost, facilitating the debugging and disassembly of the strain gauge 10, and improving the accuracy of the measurement results. The limit plate 8 plays a limiting role to prevent the screw rod 6 and the slide bar 7 from falling off.

Under the action of the support column 16, the box 1 is supported, and the user opens the maintenance door 19 to facilitate the maintenance and debugging of the strain gauge 10. Finally, under the action of the handle 17, the user can lift the box 1 and drive the strain gauge 10 to move.

[0028] The working principle of this embodiment is as follows: when in use, first connect the power supply, select a flat ground, clean the debris on the ground, start the fan 14, and under the strong blowing of the fan 14, ensure that there is no residual debris on the ground.

Then, the sliding support plate 15 slides the protective cover 20 downward under the action of the guide rail 21. Under the action of the protective cover 20, the interference of the external natural environment on the strain gauge 10 is reduced. Finally, under the action of the induction light 18, when someone approaches the box 1, the induction light 18 lights up to prevent users from accidentally knocking over the box 1 at night.
