[0035] Example 1

[0036] like Figure 1-4 As shown, this utility model provides a hinge performance testing device, which has a testing platform 1 and a hinge test piece body 11 on the testing platform 1. The testing platform 1 is provided with a vertical plate A21 and a vertical plate B22 that rotates relative to the vertical plate A21. The hinge test piece body 11 is connected to the vertical plate B22 and the vertical plate A21 by bolts.

[0037] The right end of the upright plate B22 is provided with a U-shaped seat 23 that abuts against the rear wall. Two screws A24 are threadedly connected to the front wall of the U-shaped seat 23. A pressure block 25 is fixedly installed at one end of the screw A24 inside the U-shaped seat 23. The pressure block 25 abuts against the front wall of the upright plate B22.

[0038] The test platform 1 is equipped with a drive assembly that drives the vertical plate B22 to rotate via the U-shaped seat 23.

[0039] Optionally, in the above technical solution, the driving component includes a rotating rod 31 that rotates around the Z-axis, a sliding rod A3 fixedly installed on the right wall of the rotating rod 31, a slider A30 slidably connected to the sliding rod A3, and the top wall of the slider A30 fixedly connected to the front wall of the U-shaped seat 23 through a connecting post 32.

[0040] Optionally, in the above technical solution, the rotating rod 31 is rotatably connected to the support plate 41 via the rotating column A42, and the left end of the rotating rod 31 is fixedly installed with the rotating column B43;

[0041] A disc 44 located in front of the rotating rod 31 is rotatably connected to the support plate 41. The disc 44 rotates around the front side of its midpoint. An annular groove is provided on the disc 44. The rotating column B43 is slidably connected in the annular groove of the disc 44.

[0042] Optionally, in the above technical solution, a groove 33 is provided on the right end of the rotating rod 31 located on the rotating column A42, a sliding rod B331 is fixedly installed in the groove 33, and a slider B34 is slidably connected to the sliding rod B331.

[0043] Multiple threaded holes are equally spaced on the slide bar B331, and a threaded hole is opened on the top wall of the slider B34. The slider B34 is connected to the slide bar B331 by bolts.

[0044] Optionally, in the above technical solution, one end of the connecting rod 35 is rotatably connected to the bottom wall of the slider B34, and the other end of the connecting rod 35 is rotatably connected to the hinge seat 36. The hinge seat 36 is fixedly installed on the right wall of the dovetail block 37.

[0045] A dovetail groove plate 45 is fixedly installed on the right wall of the support plate 41, and a dovetail block 37 is longitudinally slidably connected inside the dovetail groove plate 45.

[0046] Optionally, in the above technical solution, the upright plate A21 is fixedly installed on the right wall of the counterweight box 12. The counterweight box 12 is a hollow structure with an open top wall. Connecting ears 13 are fixedly installed at the four corners of the bottom wall of the counterweight box 12. The test platform 1 has four threaded holes corresponding to the connecting ears 13.

[0047] Furthermore, columns 4 are fixedly installed at the four corners of the bottom wall of the support plate 41. The columns 4 are fixedly installed on the test platform 1. A drive motor 46 is fixedly installed on the bottom wall of the support plate 41 through a motor base. The output shaft of the drive motor 46 extends upward and its end is connected to the bottom wall of the disk 44. The support plate 41 has through holes for the drive motor 46 to connect with the disk 44. The connection position between the output shaft of the drive motor 46 and the disk 44 is the front side of the midpoint of the disk 44.

[0048] Since the upright plate B22 is hinged to the upright plate A21 via the hinge test piece body 11 (the counterweight box 12 is fixed on the test platform 1 via the connecting ear 13, or a counterweight is added to the counterweight box 12 so that the position of the upright plate A21 on the counterweight box 12 remains unchanged during the test), the rotation path on the right side of the upright plate B22 is consistent. No matter the opening angle of the upright plate B22, it always opens along an arc.

[0049] This device allows for adjustment of the opening angle by adjusting the position of slider B34 on the rotating rod 31, while maintaining the same rotation path.

[0050] Working principle:

[0051] In use, the hinge to be tested is installed on the upright plate A21 and the upright plate B22 with bolts, the U-shaped seat 23 is placed on the right side of the upright plate B22, and the screw A24 is turned to drive the pressure block 25 to press the upright plate B22, so that the upright plate B22 moves with the U-shaped seat 23.

[0052] The drive motor 46 is started to drive the disc 44 to rotate in place, so that the disc 44 rotates around the motor shaft, thereby causing the rotating column B43 to rotate around the annular groove, which in turn causes the left and right ends of the rotating rod 31 to swing back and forth around the rotating column A42. The dovetail block 37 is always longitudinally slidably connected in the dovetail groove plate 45. Under this constraint, the slider A30 drives the U-shaped seat 23 to move back and forth through the connecting column 32. At this time, the upright plate B22 can drive the hinge test piece body 11 to open and close back and forth.

[0053] When it is necessary to adjust the opening and closing angle, remove the bolt on the slider B34 and move it on the slide bar B331. After moving it to the appropriate position, tighten the bolt. Since the rotating rod 31 is restricted by the slider B34 and the dovetail groove plate 45, the closer the slider B34 is to the slide bar A3, the larger the rotation angle, and the farther the slider B34 is from the slide bar A3, the smaller the rotation angle.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
