DETAILED DESCRIPTION

[0028] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Embodiment 1 of the present utility model:

[0030] like Figure 1-Figure 2 The utility model proposes an anti-glare plate impact test protective member, comprising a first protective plate 1, a second protective plate 2, a third protective plate 3 and a fourth protective plate 4; the first protective plate 1, the second protective plate 2, the third protective plate 3 and the fourth protective plate 4 are sequentially connected to form a protective frame, the protective frame is a rectangular frame, and can be made of stainless steel. The protective frame can be made by an integrated molding process or fixed by welding. The protective frame is used to surround the placement area on the test bench 5 for placing the anti-glare plate from all sides.

[0031] The tops of the first guard plate 1, the second guard plate 2, the third guard plate 3 and the fourth guard plate 4 are flush and 30 to 50 centimeters higher than the placement area. By surrounding the placement area on the test bench 5 for placing the anti-glare plate with a protective frame from all sides, the falling ball that hits the anti-glare plate can be protected during the test to prevent the falling ball from bouncing out and injuring the test personnel after hitting the anti-glare plate. The protective member of the utility model has a simple structure, is light and convenient, and is easy to take and put.

[0032] As an implementation method, the protective frame cover is arranged on the test bench 5, and an avoidance groove 31 for avoiding the test bench 5 is opened under the third guard plate 3; the test bench 5 passes through the avoidance groove 31, and the gap size between the test bench 5 and the avoidance groove 31 is smaller than the diameter of the falling ball. In this way, the falling ball can be prevented from falling out of the gap between the test bench 5 and the avoidance groove 31.

[0033] When in use, the anti-glare plate is first fixed to the placement area, and then the protective frame cover of the protective member is placed on the test bench 5, so that the placement area is located in the protective frame, and then the test can be carried out. After the test, the protective frame is removed and the falling ball is taken out. The utility model effectively avoids the falling ball from popping out of the test bench and injuring the test personnel during the test.

[0034] In order to shorten the test time and improve the test efficiency, the second guard plate 2 of the protection frame can be provided with a first mounting through hole 21 for the anti-glare plate to be tested to pass through. The second guard plate 2 is arranged opposite to the fourth guard plate 4, and the fourth guard plate 4 is provided with a second mounting through hole 41 for the anti-glare plate to be tested to pass through; the first mounting through hole 21 is aligned with the second mounting through hole 41 and has the same size.

[0035] In this way, when the impact test is performed on the upper, middle and lower parts of the anti-glare plate, the anti-glare plate can be first fixed to the placement area so that the upper part of the anti-glare plate is opposite to the falling ball to be dropped, and then the protective part can be installed, and then the test can be performed. After the test, there is no need to remove the protective part, and only the anti-glare plate can be released and moved in the direction from the first mounting through hole 21 to the second mounting through hole 41 so that the middle part of the anti-glare plate is opposite to the falling ball to be dropped. After the anti-glare plate is fixed, the impact test is performed, and then the anti-glare plate is released and moved in the direction from the first mounting through hole 21 to the second mounting through hole 41 so that the lower part of the anti-glare plate is opposite to the falling ball to be dropped. After the anti-glare plate is fixed, the impact test is performed. The anti-glare plate can be released again and moved in the direction from the first mounting through hole 21 to the second mounting through hole 41 so that the lower part of the anti-glare plate is opposite to the falling ball to be dropped. After the anti-glare plate is fixed, the impact test is performed. The protective part does not need to be removed from the test device during the entire test process, and the impact test on the upper, middle and lower parts of the anti-glare plate can be completed, thereby improving the test efficiency.

[0036] For easy taking, the protection frame is provided with a handle 6, which is fixedly arranged on the outer side of the protection frame. In specific implementation, the handle 6 can be provided with two, and the two handles 6 are respectively arranged on a relative guard plate of the protection frame.

However, in order to prevent the falling ball from falling out of the first mounting hole 21 and the second mounting hole 41, a sealing plate 7 for closing the first mounting hole 21 can be slidably installed on the second guard plate 2, and a sealing plate 7 for closing the second mounting hole 41 is also slidably installed on the fourth guard plate 4. Before the test starts, the corresponding sealing plate 7 is used to seal the first mounting hole 21 and the second mounting hole 41.

[0040] As an embodiment, two mounting strips 8 are fixedly mounted on the second guard plate 2. The two mounting strips 8 are respectively located on both sides of the first mounting through hole 21. Slide grooves 81 are provided on the opposite sides of the two mounting strips 8. The two sides of the sealing plate 7 are respectively slidably mounted in the two slide grooves 81. Two mounting strips 8 are also provided on the fourth guard plate 4. The two mounting strips 8 are respectively located on both sides of the first mounting through hole 21. Slide grooves 81 are provided on the opposite sides of the two mounting strips 8. The two sides of the sealing plate 7 are respectively slidably mounted in the two slide grooves 81.

[0041] In order to facilitate pulling the closing plate 7 to move along the sliding groove 81 , a handle 9 is provided on the closing plate 7 .

[0042] See also Figure 5-Figure 6 The utility model also discloses an anti-glare plate impact test device, comprising a test bench 5, a column 10, a fixing rod 11 and the above-mentioned protective member;

[0043] The placement area on the test bench 5 is located on the upper surface of the test bench 5, and the placement area is provided with fastening bolts 12 for fixing the anti-glare plate;

[0044] The lower end of the column 10 is fixedly connected to the test bench 5 by bolts. The column 10 is vertically arranged with the test bench 5 and the column 10 is arranged at one edge of the test bench 5. The test bench 5 is a rectangular table. The other end of the column 10 is connected to one end of the fixing rod 11. The fixing rod 11 is arranged horizontally. The lower surface of the fixing rod 11 away from the column 10 is provided with an electromagnet for fixing the falling ball. The falling ball is located directly above the placement area. The falling ball and the fixing rod 11 can also be arranged in other ways. The protective frame of the protective member surrounds the placement area on the test bench 5 for placing the anti-glare plate from all sides, and the column 10 is located outside the protective member.

[0045] The column 10 and the fixed rod 11 can be fixedly connected or slidably connected. When the slidably connected, the fixed rod 11 can move up and down along the column to adjust the falling height of the falling ball. When the fixed rod 11 is slidably connected to the column 10, a locking member is also required on the fixed rod 11 to fix the fixed rod 11 to the column 10 when the fixed rod 11 moves to a suitable height.
