[0001] This utility model relates to the field of hinge spring performance testing technology, and in particular to a comprehensive hinge spring performance testing device. Background Technology

[0002] Hinge springs are widely used in various mechanical equipment, such as doors and windows, furniture, automobiles, and industrial automation equipment. To ensure the reliability and safety of these springs in actual use, rigorous performance testing is essential. However, existing hinge spring performance testing equipment typically employs relatively simple and singular testing methods, making it difficult to meet the needs of comprehensive performance evaluation of hinge springs from multiple perspectives.

[0003] Therefore, a hinge spring comprehensive performance testing device has now been developed that can simultaneously test the fatigue performance and rebound performance of hinge springs, so as to facilitate a comprehensive performance evaluation of hinge springs. Utility Model Content

[0004] To overcome the shortcomings of existing hinge spring performance testing devices, which typically employ simple and singular testing methods and are insufficient to meet the needs of comprehensive performance evaluation of hinge springs, this invention provides a hinge spring comprehensive performance testing device capable of simultaneously testing the fatigue performance and rebound performance of hinge springs, thereby facilitating comprehensive performance evaluation of hinge springs.

[0005] The technical solution of this utility model is: a hinge spring comprehensive performance testing device, including a base, a sliding frame, a pressing block, a telescopic spring, a support frame, a screw, a pressing plate, a locking assembly, and a testing assembly. The sliding frame is slidably connected to the left side of the base, and the pressing block is connected to the right side of the sliding frame. The pressing block is slidably connected to the base. Telescopic springs are connected to the base at both the front and rear of the pressing block. The support frame is connected to the upper left side of the pressing block and is slidably connected to the base. The screw is threadedly connected to the upper part of the support frame, and the pressing plate is rotatably connected to the lower side of the screw. The base is provided with a locking assembly that can lock the hinge, and the base is also provided with a testing assembly that can test the comprehensive performance of the hinge spring.

[0006] Furthermore, an anti-slip seat is provided on the underside of the base.

[0007] Furthermore, a knob is provided on the upper side of the screw.

[0008] Furthermore, a soft pad is provided on the underside of the pressing plate.

[0009] Furthermore, the positioning component includes a wedge block and a limiting rod. The wedge block is slidably connected to the inner right side of the base. The pressing block is pressed and engaged with the wedge block. Limiting rods are connected to the upper sides of both the front and rear parts of the wedge block, and the limiting rods are slidably connected to the base.

[0010] Furthermore, the detection components include a motor, a missing gear, a lever, a pressure sensor, a slide rail, a mounting bracket, and a scanning electron microscope.

Detailed Implementation

[0018] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] A comprehensive performance testing device for hinge springs, such as Figures 1-5As shown, the device includes a base 1, a sliding frame 2, a pressing block 3, a telescopic spring 4, a support frame 5, a screw 6, a pressing plate 7, a locking assembly, and a detection assembly. The sliding frame 2 is slidably connected to the left side of the base 1. An anti-slip seat is provided on the lower side of the base 1 for stable placement. The pressing block 3 is connected to the right side of the sliding frame 2 and is slidably connected to the base 1. The telescopic spring 4 is connected to both the front and rear parts of the pressing block 3 and the base 1. The support frame 5 is connected to the upper left side of the pressing block 3 and is slidably connected to the base 1. The screw 6 is threadedly connected to the upper part of the support frame 5. A knob is provided on the upper side of the screw 6 for easy gripping. The pressing plate 7 is rotatably connected to the lower side of the screw 6. A soft pad is provided on the lower side of the pressing plate 7 to prevent damage to the hinge. The base 1 is equipped with a locking assembly and a detection assembly.

[0020] like Figures 1-3 As shown, the positioning assembly includes a wedge block 8 and a limiting rod 9. The wedge block 8 is slidably connected to the inner right side of the base 1. The pressing block 3 is pressed and engaged with the wedge block 8. The limiting rod 9 is connected to the upper front and rear sides of the wedge block 8. The limiting rod 9 is slidably connected to the base 1.

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, the detection assembly includes a motor 10, a missing gear 11, a lever 12, a pressure sensor 121, a slide rail 13, a mounting bracket 14, and a scanning electron microscope 15. The motor 10 is connected to the front of the middle part of the base 1. The missing gear 11 is connected to the output shaft of the motor 10. The missing gear 11 is also rotatably connected to the front right part of the base 1. The missing gears 11 mesh with each other. The lever 12 is connected to the eccentric position of the missing gear 11 on the right side. The pressure sensor 121 is connected to the middle of the lever 12. The slide rail 13 is connected to the rear right part of the base 1. The lever 12 is slidably connected to the slide rail 13. The mounting bracket 14 is connected to the rear right part of the base 1. The mounting bracket 14 is located to the left of the slide rail 13. The scanning electron microscope 15 is connected to the upper part of the mounting bracket 14.

[0022] When using this utility model, first place the base 1 in the hinge spring performance testing area, then pull the sliding frame 2 to the left, causing the support frame 5 and the pressing block 3 to move to the left. At this time, the pressing block 3 disengages from the wedge block 8, and the wedge block 8, under the action of gravity, causes the limiting rod 9 to move downward. The telescopic spring 4 is compressed and contracted. Then, place the hinge spring with the hinge installed on the base 1, so that the slot on the hinge is above the limiting rod 9. Then release the sliding frame 2, and the telescopic spring 4 rebounds, causing the sliding frame 2, the pressing block 3, and the support frame 5 to move to the right and reset. At this time, the pressing block 3 pushes the wedge block 8 upward, so that the limiting rod 9 is inserted into the slot on the hinge. Then rotate the screw 6 to move the pressing plate 7 downward to press the hinge. This fixes the hinge to the base 1. After fixing, the motor 10 is started, driving the missing gear 11 to rotate, causing the missing gear 11 to mesh and rotate, driving the actuating rod 12 to rotate, causing the actuating rod 12 to move up and down along the slide rail 13, actuating the other hinge to rotate. The scanning electron microscope 15 on the mounting bracket 14 is used to inspect the surface of the spring to observe whether there are cracks, peeling or other signs of damage, and to test the fatigue performance of the hinge spring. When the hinge rotates to reset, it contacts the actuating rod 12. The pressure sensor 121 monitors the pressure change when the hinge rotates to reset and contacts the actuating rod 12, judging the rebound performance of the hinge spring. This allows for simultaneous detection of the fatigue performance and rebound performance of the hinge spring, facilitating a comprehensive performance evaluation of the hinge spring.
