Description

Technical Field

[0001] This utility model relates to the field of anti-glare panel testing, and in particular to an experimental device for testing the impact resistance of anti-glare panels. Background Technology

[0002] Anti-glare panels are traffic safety facilities installed on the central median strip of highways. Their main function is to prevent glare from oncoming vehicle headlights when driving at night through their unique structural design, thereby reducing the incidence of traffic accidents and ensuring driving safety.

[0003] The impact resistance of anti-glare panels is a very important technical indicator. It directly relates to whether the anti-glare panel can maintain its structural integrity and continue to perform its anti-glare function when subjected to accidental impacts (such as vehicle collisions, foreign object impacts, etc.).

[0004] The impact resistance test method for anti-glare panels usually involves dropping an iron ball of a specific mass from a certain height to impact the anti-glare panel sample. The degree of deformation and damage of the anti-glare panel after the impact are then evaluated to ensure that it can withstand a certain amount of external impact without losing its function in practical applications.

[0005] However, after the iron ball falls and collides with the specimen, it bounces up and falls again, causing the iron ball to collide with the specimen multiple times during the repeated bouncing process, which affects the accuracy of the experimental results and needs to be improved. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a test device for the impact resistance performance of anti-glare panels, which improves the accuracy of the experiment.

The base is horizontally set on the ground, and mounting seats for supporting the anti-glare panel are horizontally arranged on both sides of the base. The support frame is vertically set on the base, and the suspension is horizontally set at the upper end of the support frame and located directly above the base. The electromagnetic fixing seat is set at the front end of the suspension and is used to attract the iron ball. The winding mechanism includes a turntable, a motor, and a pull rope. The motor is set on the suspension, the turntable is set on the motor shaft, and the pull rope is wound around the turntable and fixed to the iron ball.

[0008] In a preferred embodiment, the present invention can be further configured as follows: a gantry frame spanning the anti-glare plate is provided on the mounting base, a pressure rod for pressing the upper surface of the anti-glare plate is provided horizontally on the gantry frame, and a screw is vertically threadedly connected to the gantry frame, the screw being rotatably connected to the pressure rod.

[0010] In a preferred embodiment, the present invention can be further configured such that: a guide tube is provided on the suspension below the turntable, and the guide tube allows the pull rope to pass through.

[0011] In a preferred embodiment, the present invention can be further configured such that the pull rope is provided with a fixing rod threadedly connected to the iron ball.

[0012] In a preferred embodiment, the present invention can be further configured such that: both ends of the gantry are provided with protective rods that are vertically upward, and a protective net is provided between the plurality of protective rods.

[0013] In a preferred embodiment, the present invention can be further configured such that: the lower end of the protective rod is provided with a locking rod that is inserted into the mounting base.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, an anti-glare plate impact resistance test device includes a base 1, a support frame 2, a suspension 3, an electromagnetic fixing seat 4, an iron ball 5, and a winding mechanism 6.

[0024] like Figure 1 , Figure 2 As shown, the base 1 is horizontally placed on the ground, and multiple levelers 11 are provided on its lower end to adjust the levelness of the base 1. The support frame 2 is vertically placed on the base 1, and the suspension 3 is horizontally placed on the upper end of the support frame 2 and directly above the base 1. The electromagnetic fixing seat 4 is placed at the front end of the suspension 3 and is used to attract the iron ball 5.

[0025] like Figure 1 , Figure 2 As shown, the winding mechanism 6 includes a turntable 61, a motor 62, and a pull rope 63. The motor 62 is mounted on the suspension 3, the turntable 61 is mounted on the shaft of the motor 62, and the pull rope 63 is wound around the turntable 61 and fixed to the iron ball 5. The length of the pull rope 63 is greater than the height of the support frame 2.

[0026] When testing the impact resistance of the anti-glare panel, place the anti-glare panel on the base 1, and then attach the iron ball 5 to the electromagnetic mounting base 4. At the same time, the turntable 61 is in a released state, allowing the pull rope 63 to hang freely. Subsequently, the power to the electromagnetic mounting base 4 is turned off. Since the length of the pull rope 63 is greater than the height of the support frame 2, the iron ball 5 can fall freely after the electromagnetic mounting base 4 is de-energized, and the pull rope 63 will not exert any pulling force on the iron ball 5.

[0027] When the electromagnetic mounting base 4 is de-energized, the motor 62 starts and drives the turntable 61 to rotate. As the iron ball 5 descends, the pull rope 63 is gradually wound up. When the iron ball 5 hits the anti-glare plate and bounces up, the turntable 61 continues to rotate and wound up the pull rope 63. At this time, the iron ball 5 can be pulled and lifted, avoiding the iron ball 5 from falling and hitting the anti-glare plate again, preventing secondary damage to the anti-glare plate, and improving the accuracy of the experiment.

[0028] like Figure 1 , Figure 2 As shown, the suspension 3 is equipped with a guide tube 31 located below the turntable 61. The guide tube 31 allows the pull rope 63 to pass through. Therefore, when the iron ball 5 swings, the guide tube 31 limits the upper end of the pull rope 63, ensuring stable winding of the pull rope 63. The pull rope 63 is equipped with a fixing rod 64 threaded to the iron ball 5 to achieve a detachable connection between the pull rope 63 and the iron ball 5, facilitating the switching of whether to use the pull rope 63.

[0029] like Figure 1 , Figure 2 As shown, mounting seats 7 for supporting anti-glare panels are arranged horizontally on both sides of the base 1. A gantry frame 71 spans the anti-glare panel on the mounting seat 7. A pressure rod 72 for pressing the upper surface of the anti-glare panel is arranged horizontally on the gantry frame 71. A screw 73 is vertically threaded on the gantry frame 71 and is rotatably connected to the pressure rod 72.

[0030] like Figure 1 , Figure 2 As shown, both ends of the gantry frame 71 are vertically provided with insertion rods 74. The mounting base 7 is provided with insertion holes 75 for insertion of the insertion rods 74. The outer wall of the insertion rods 74 is provided with hooks 76. The mounting base 7 is provided with a row of locking holes 77 for the hooks 76 to pass through.

[0031] When it is necessary to fix the anti-glare panel, place the anti-glare panel on the mounting base 7 on the base 1, then take out the gantry frame 71 and insert the insert rods 74 at both ends of the gantry frame 71 into the insertion holes 75 on the mounting base 7. Then press the gantry frame 71 down to make the insert rods 74 slide in the insertion holes 75, and use the cooperation of the hooks 76 and the locking holes 77 to fix the gantry frame 71, thereby achieving the initial adjustment of the height position of the gantry frame 71. Then rotate the screw 73 to control the pressure rod 72 to slide down, thereby pressing and fixing the anti-glare panel, thus achieving the quick fixing and installation of the anti-glare panel.

[0032] Meanwhile, when testing multiple points of the anti-glare plate, simply loosening and tightening the screw 73 and controlling the reciprocating motion of the pressure rod 72 can achieve the adjustment of the tightness of the anti-glare plate, thereby realizing convenient and quick adjustment of the position of the anti-glare plate on the base 1 and improving testing efficiency.

[0033] like Figure 1 , Figure 2 As shown, both ends of the gantry 71 are vertically equipped with guard rods 8, and the lower end of the guard rods 8 is equipped with locking rods 81 that connect to the mounting bases 7. Protective nets 82 are installed between the guard rods 8. Therefore, by setting up the protective nets 82, the iron ball 5 is blocked, preventing it from hitting the inspection workers and ensuring safety during the inspection process.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
