Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass testing technology, and in particular to a testing device for flat glass. Background Technology
[0002] Flat glass, also known as clear glass or solid glass, is generally composed of sodium calcium. It has properties such as light transmission, transparency, heat insulation, sound insulation, wear resistance, and resistance to climate change. It can be classified by thickness into thin glass, thick glass, and extra-thick glass. According to the surface condition, it can be classified into ordinary flat glass, patterned glass, polished glass, float glass, etc. Flat glass can also be made into products with different colors and special properties through coloring, surface treatment, and composite processes. In the production process of flat glass, in order to verify the quality of flat glass, it is necessary to test the impact resistance of the glass sheet. However, when the glass breaks during the test, it will shatter in all directions and be difficult to clean.
[0003] For example, a high-strength flat glass testing device disclosed in Chinese patent literature (publication number: CN213689242U) can be used to test the glass plate by adjusting the spring through the adjustment mechanism and the impact mechanism. This allows for the adjustment of the impact head of the impact mechanism to change the impact force between the impact head and the glass plate, and can perform impact testing on the glass plate with different impact forces. The adjustment is convenient and fast.
[0004] However, in actual operation, because the workbench is open, when the glass breaks during testing, it is not only easy for the glass to shatter and injure the operator, but it also increases the difficulty of subsequent cleaning. Furthermore, the use of a single type of impact head for testing cannot comprehensively detect the various impacts that flat glass is subjected to in daily use, and cannot fully assess its ability to withstand various impacts in actual use. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor protective performance when testing flat glass and the difficulty of using a single type of impact head to reflect the resistance to various impacts.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A testing device for flat glass includes a testing platform, and a protective collection mechanism is provided above the testing platform;
[0008] The protective collection mechanism includes a protective cover, an opening and closing door on the front of the protective cover, movable rods slidably sleeved on the inner walls of both sides of the protective cover, one end of the movable rod passing through to one side of the protective cover and fixedly connected to a gripping block, the other end of the movable rod being fixedly connected to a cleaning push plate, and a mounting plate being fixedly connected to one side of the cleaning push plate.
[0009] An impact switching mechanism is installed above the testing platform.
[0010] Preferably, the two ends of the mounting plate are in contact with the front and rear inner walls of the protective cover, respectively, and a hand-tightening screw is threadedly connected to the inner wall of the mounting plate. The lower end of the hand-tightening screw is rotatably connected to a pressure plate through a bearing.
[0011] Preferably, the upper end of the pressure plate is fixedly connected with symmetrically distributed guide rods, the upper ends of the two guide rods both penetrate and extend to the top of the mounting plate, a material discharge port is provided above the detection table, and symmetrically distributed extension ports are provided on the front and rear inner walls of the material discharge port.
[0012] Preferably, a collection housing is fixedly connected to the lower end of the testing platform, the upper end of the collection housing is connected to the lower ends of the discharge port and the extension port respectively, and a collection box is movably inserted into the front of the collection housing.
[0013] Preferably, the impact switching mechanism includes a mounting base, and adjusting rods are rotatably connected to the inner walls of both sides of the mounting base via bearings. A triangular switching block is fixedly sleeved on the outside of the adjusting rod, and locking grooves distributed in a ring array are opened on the outside of the adjusting rod.
[0014] Preferably, one end of the adjusting rod is fixedly connected to a hand-held turntable, one side of the mounting base is fixedly connected to a support plate, a locking rod is slidably sleeved on the inner wall of the support plate, the lower end of the locking rod is movably inserted into the inner wall of one of the locking grooves, and the upper end of the locking rod is fixedly connected to a pulling block.
[0015] Preferably, a return spring is fixedly connected to the lower end of the pull block, one end of the return spring is fixedly connected to the upper end of the support plate, a scale block is fixedly connected to the upper end of the mounting base, and the upper end of the scale block passes through the protective cover and is fixedly connected to a lifting plate.
[0016] Preferably, the front of the scale block is provided with limiting slots arranged in a linear array, one of the limiting slots has a limiting plate slidably inserted into its inner wall, the lower end of the limiting plate contacts the upper end of the protective cover, the lower end of the lifting plate is fixedly connected to symmetrically distributed limiting rods, the lower ends of the two limiting rods pass through the protective cover and are fixedly connected to the upper end of the mounting base.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] In this invention, the protective cover of the protective collection mechanism is equipped with an opening and closing door with an observation window on the front. During testing, the opening and closing door is closed to form a closed space, preventing glass shards from scattering and injuring people. The observation window allows for real-time viewing of the testing process, balancing safety and visualization needs. After testing, the sliding rod drives the cleaning push plate, which can push the debris on the surface of the testing table to the discharge port. Combined with the extension port, the cleaning range is expanded, thereby achieving the effect of easy cleaning of glass shards.
[0019] The triangular switching block rotates synchronously via the adjusting rod in the impact switching mechanism, allowing for rapid switching between different types of impact heads to simulate complex working conditions such as sharp point impacts and blunt surface impacts. Furthermore, the triangular switching block is locked in position by inserting a locking rod into the locking groove. Pulling up the block disengages the locking rod from the locking groove, unlocking the adjusting rod and facilitating the switching of impact heads. This not only ensures the stability of impact detection but also solves the problem of incomplete detection with a single impact head. Attached Figure Description

[0030] Example
[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a testing device for flat glass, including a testing platform 1, with a protective collection mechanism and an impact switching mechanism respectively arranged on the top of the testing platform 1, and has functions such as directional cleaning and collection of debris, which is suitable for testing scenarios of the impact resistance performance of flat glass, and comprehensively improves the testing safety, testing dimensions and operation efficiency.
[0032] A protective cover 2 is installed above the testing table 1, and the front is equipped with an opening and closing door 21 with an observation window. When testing, the opening and closing door 21 is closed to form a fully enclosed space above the testing table 1, which can confine the flying fragments generated by the glass breakage inside the cover to avoid scratches and cuts to the operators. The observation window is made of high-strength transparent material with a thickness of ≥5mm, which not only ensures the visibility of the testing process, but also has impact resistance to prevent it from being penetrated by fragments.
[0033] The inner walls of both sides of the protective cover 2 are slidably fitted with movable rods 22. One end of the rod passes through the cover and is connected to a gripping block 23 for easy manual operation. The other end of the movable rod 22 is fixed to a cleaning push plate 24. One side of the push plate is connected to a mounting plate 25. The inner wall of the mounting plate 25 is threaded with a hand-tightening screw 26. The lower end of the screw is rotatably connected to a pressure plate 27 via a bearing. The upper end of the pressure plate 27 is fixed with symmetrically distributed guide rods 28 that pass through the mounting plate 25 to prevent rotation. An inclined accordion cover is installed on the other side of the cleaning push plate 24 to prevent the accumulation of splashed glass fragments on the other side of the cleaning push plate 24. The fragments slide down through the stretched inclined accordion cover to the discharge port 29 for collection. The accordion cover is existing technology and is therefore not shown in the figure.
[0034] The sliding rod 22 can adjust the horizontal position of the cleaning push plate 24 and the mounting plate 25 to accommodate different sizes of flat glass. By turning the hand screw 26, the pressure plate 27 moves vertically downward along the guide rod 28 and flexibly fixes the glass through the lower rubber pad to avoid damaging the glass surface during clamping and to ensure that the glass does not shift during testing.
[0035] After the test is completed, push the gripping block 23 to drive the movable rod 22 to slide. The cleaning push plate 24 can push the glass fragments on the surface of the test table 1 to the discharge port 29. The discharge port 29 has extension ports 210 at the front and back to expand the coverage of the fragment cleaning and solve the problem of difficult cleaning of fragments scattered in open test.
[0036] The lower end of the testing platform 1 is fixed with a collection housing 211, and its upper end is connected to the discharge port 29 and the extension port 210. The front of the collection housing 211 is movably inserted into the collection box 212. After the glass breaks, some fragments fall directly into the collection box 212 through the discharge port 29 due to gravity. The remaining debris is pushed by the cleaning push plate 24 and also enters the collection box 212 through the discharge port 29 or the extension port 210, so as to realize the centralized collection of debris. The collection box 212 adopts a drawer-type design, which makes it convenient to pull out and clean the debris, and can avoid the debris residue from affecting the life of the equipment.
[0037] A mounting base 3 is installed above the testing platform 1. The inner walls on both sides are rotatably connected to the adjusting rod 31 via bearings. One end is connected to the hand-held turntable 34 for easy manual operation. The adjusting rod 31 is externally fixedly fitted with a triangular switching block 32, which integrates three types of impact heads: conical, flat, and round, to simulate point impact from sharp objects, surface impact from blunt objects, and oblique impact from curved objects, respectively.
[0038] Rotating the hand-held turntable 34 causes the adjusting rod 31 to drive the triangular switching block 32 to rotate synchronously, which can quickly complete the switching of impact heads and cover the complex impact scenarios encountered in the daily use of flat glass, such as stone impacts during construction and furniture falling impacts, thus solving the problem of insufficient detection dimensions of traditional single impact heads.
[0039] The adjusting rod 31 has a ring-shaped array of locking grooves 33 on its outside; the mounting base 3 has a fixed support plate 35 on one side, and a sliding locking rod 36 is attached to its inner wall. The upper end is connected to a pulling block 37, and the lower end is adapted to the locking groove 33. The lower end of the pulling block 37 is connected to a reset spring 38, which is fixed to the upper end of the support plate 35.
[0040] Under normal conditions, the return spring 38 pushes the lower end of the latch 36 into the locking groove 33, locking the position of the triangular switching block 32, ensuring that the impact head does not shift during detection and improving detection repeatability.
[0041] Lifting the pull block 37 causes the locking lever 36 to overcome the elastic force of the reset spring 38 and move upward to disengage from the locking groove 33, unlocking the adjusting lever 31. At this time, the hand-held turntable 34 can be freely rotated to switch the impact head, which can be easily completed by one person.
[0042] The upper end of the mounting base 3 is fixed with a scale block 39, which passes through the protective cover 2 and is connected to the lifting plate 310. The scale block 39 has linearly arrayed limiting slots 311 on its front side, and a limiting plate 312 is inserted therein. The lower end of the lifting plate 310 is fixed with symmetrically distributed limiting rods 313, which pass through the protective cover 2 and are fixed to the mounting base 3.
[0043] Pull out the limiting plate 312, hold the lifting plate 310 and lift the mounting base 3 vertically along the limiting rod 313. Use the height mark on the scale block 39 to precisely adjust the height of the impact head from the glass to simulate the impact of the glass under different working conditions.
[0044] After adjusting to the target height, insert the limiting plate 312 into the corresponding limiting slot 311, with its lower end contacting the upper end of the protective cover 2 to lock the height of the mounting base 3, ensuring that the mounting base 3 falls vertically during the impact and improving detection accuracy.
[0045] The working process of this utility model:
[0046] Step 1: Open the opening and closing door 21, place the flat glass to be tested on the testing table 1, slide the movable rod 22 to bring the cleaning push plate 24 close to both sides of the glass; turn the hand screw 26, the pressure plate 27 moves down, and the glass is flexibly fixed by the rubber pad. Close the opening and closing door 21 to form a closed testing space. The observation window is reserved for a visual testing channel. If it is necessary to switch the impact head, such as from flat to conical, lift the pull block 37, the locking rod 36 disengages from the locking groove 33, turn the hand grip turntable 34, the adjusting rod 31 drives the triangular switching block 32 to rotate, and after switching to the target impact head such as conical, release the pull block 37, the reset spring 38 pushes the locking rod 36 into the corresponding locking groove 33 to lock the impact head.
[0047] Step 2: Remove the limiting plate 312, hold the lifting plate 310, and lift the mounting base 3 to the target height according to the scale block 39. Insert the limiting plate 312 to lock the height of the mounting base 3, release the lifting plate 310, and the mounting base 3 will fall. The impact head under the triangular switching block 32 will impact the glass. The height can be repeatedly adjusted to perform multiple rounds of impact tests with different energies until the glass breaks. After the glass breaks, some fragments will fall into the collection box 212 through the discharge port 29. The two cleaning push plates 24 will move relative to each other through the holding block 23 until the two cleaning push plates 24 move above the extension port 210. At this time, the cleaning push plates 24 will push the glass fragments remaining above the test table 1 into the discharge port 29 for cleaning. Finally, they will be collected in the collection box 212. The collection box 212 can be removed periodically to clean the fragments and then inserted back in.
[0048] 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.
