[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1 - Figure 5 The figure shows a strength testing device for automobile sunroof glass, including a support frame 1, which has two groups symmetrically arranged. A rack 2 is fixedly connected to the opposite side of the support frame 1, and a gear 5 is meshed with the rack 2 away from the support frame 1. A lifting block 3 is provided on the outside of the gear 5, and a rotating groove 4 is opened near the lifting block 3. The gear 5 is rotatably connected to the inside of the rotating groove 4, and a rotating rod 6 is fixedly connected to the inside of the rotating groove 4. The rotating rod 6 is rotatably connected to the inside of the rotating groove 4, and the rotating rod 6 is fixedly connected to a rotating wheel 7 away from the rotating groove 4. The rotating wheel 7 is rotatably connected to one side of the lifting block 3, and a positioning component is provided on the outside of the rotating wheel 7. The positioning component includes a plastic paddle 8, which is arc-shaped and fixedly connected to the outside of the rotating wheel 7. There are multiple groups of plastic paddles 8 arranged in a circumferential array, and the outside of the plastic paddle 8 abuts against a card block 9. The outside of the card block 9 is fixedly connected to a pressing shell 10. The pressing shell 10 is arranged on one side of the lifting block 3, and the inside of the pressing shell 10 away from the card block 9 is a sliding surface.
[0020] When working, place the glass on the fixed platform 16, press the pressing shell 10, disengage the block 9 from the plastic paddle 8, move the lifting block 3 up, rotate the rotating rod 6 and the gear 5, and slide the gear 5 along the rack 2 fixed to the support frame 1. At this time, move the pressing shell 10 to make the block 9 and the plastic paddle 8 abut against each other, so that the lifting block 3 will not move up, and then release the lifting block 3, so that the impact hammer 17 can impact the top of the car sunroof glass, and when the lifting block 3 rebounds due to the force of the car window glass, the block 9 will jam the plastic paddle 8, and the plastic paddle 8 will not rotate, and the plastic paddle 8 restricts the wheel 7 to prevent the rotating rod 6 from driving the gear 5 to rotate, and the gear 5 will limit the lifting block 3 to prevent the lifting block 3 from moving, thereby achieving the effect of preventing the impact hammer 17 from rebounding, and solving the problem that the impact hammer 17 will rebound after the impact, resulting in the impact hammer 17 falling twice and the impact force on the glass cannot be accurately controlled.
[0021] See also Figure 1 - Figure 5In the figure, a telescopic slot 11 is opened on the side of the pressing shell 10 near the lifting block 3, and the pressing shell 10 is slidably connected to the inside of the telescopic slot 11. The telescopic slot 11 is arranged in a stepped shape, and a positioning block 12 is fixedly connected to one end of the pressing shell 10 near the telescopic slot 11. The positioning block 12 is arranged in a rectangular shape, and the positioning block 12 is slidably connected to the inside of the telescopic slot 11. A spring 13 is fixedly connected between the positioning block 12 and the telescopic slot 11, and a screw rod 18 is slidably connected to the inside of the lifting block 3. The bottom of the screw rod 18 is fixedly connected to an impact hammer 17, and the outside of the screw rod 18 is slidably connected to a gasket 19 near the top position. The gasket 19 abuts against the top of the lifting block 3, and the outside of the screw rod 18 is rotatably connected to the top of the gasket 19. The bottom of the support frame 1 is fixedly connected to a base 15, and the top of the base 15 is fixedly connected to a fixed platform 16 near the center position. The top of the rack 2 is fixedly connected to a blocking block 14, and the blocking block 14 abuts against the top of the lifting block 3 near the rotating slot 4.
[0022] During operation, the rectangular structure of the positioning block 12 slides inside the telescopic slot 11, ensuring that the blocking block 9 can stably restrict the plastic pick 8 to prevent the plastic pick 8 from reversing. When the pressing shell 10 is normally released, the spring 13 will push the positioning block 12 to clamp the pressing shell 10, and the blocking block 9 will stably fix the plastic pick 8. When an impact hammer 17 with a different contact surface is needed, the nut 20 can be rotated to remove the gasket 19, so that the impact hammer 17 can be replaced, and the base 15 can stably fix the fixing platform 16 to achieve a stable impact effect. The blocking block 14 can prevent the lifting block 3 from slipping off from the outside of the support frame 1 and the rack 2.
[0023] Working principle: Place the glass on the fixed platform 16, press the pressing shell 10 to disengage the block 9 from the plastic paddle 8, move the lifting block 3 upward, rotate the rotating rod 6 and the gear 5, and the gear 5 slides along the rack 2 fixed to the support frame 1. At this time, move the pressing shell 10 to allow the block 9 and the plastic paddle 8 to abut against each other, so that the lifting block 3 will not move upward, and then release the lifting block 3, so that the impact hammer 17 can impact the top of the car sunroof glass, and when the lifting block 3 rebounds due to the force of the car window glass, the block 9 will jam the plastic paddle 8, and the plastic paddle 8 will not rotate, and the plastic paddle 8 restricts the wheel 7 to prevent the rotating rod 6 from driving the gear 5 to rotate, and the gear 5 will restrict the lifting block 3 to prevent the lifting block 3 from moving, thereby achieving the effect of preventing the impact hammer 17 from rebounding, solving the problem. In order to solve the problem that the impact hammer 17 rebounds after the impact, causing the impact hammer 17 to fall for the second time and the impact force on the glass cannot be accurately controlled, the rectangular structure of the positioning block 12 slides inside the telescopic slot 11, ensuring that the block 9 can stably restrict the plastic pick 8 to prevent the plastic pick 8 from reversing. When the pressing shell 10 is normally released, the spring 13 will push the positioning block 12 to clamp the pressing shell 10, and the block 9 will stably fix the plastic pick 8. When it is necessary to use an impact hammer 17 with a different contact surface, the nut 20 can be turned to remove the gasket 19, so that the impact hammer 17 can be replaced, and the base 15 can stably fix the fixing platform 16 to achieve a stable impact effect. The blocking block 14 can prevent the lifting block 3 from slipping off from the outside of the support frame 1 and the rack 2.
