[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4 A hinge torque testing fixture is shown, including a fixed ring 1, a detachable connecting block 3 above the fixed ring 1, a base fixedly connected to the top of the connecting block 3, a front positioning block 4 fixedly connected to one side above the base, a rear protective plate 5 fixedly connected to one side above the base, a rear positioning block 6 fixedly connected to one side of the rear protective plate 5, a communicating insertion hole 61 between the rear protective plate 5 and the rear positioning block 6, a hinge 7 to be measured is located between the front positioning block 4 and the rear protective plate 5, a pressing device for pressing the hinge 7 chain plate is provided on one side of the front positioning block 4, a rotating collar 2 is rotatably connected to the bottom of the fixed ring 1, a connecting plate 12 fixedly connected to a torque measuring instrument is fixedly connected to one side of the rotating collar 2, and a fixing device for connecting another chain plate is fixedly connected to the top of the connecting plate 12.

[0020] To address the problem that during torque testing of existing hinges 7, one end of the hinge 7 easily disengages from the clamp, causing the hinge 7 to pop out and resulting in damage, this utility model introduces a torque testing fixture for hinges 7. First, the insert plate of the hinge 7 is inserted into the insertion hole 61. Then, the hinge 7 is bent so that the inserted hinge plate and the connecting piece of the hinge 7 are at a 90-degree angle. Then, the pressing device is pressed against the connecting piece of the hinge 7 to prevent the hinge 7 from disengaging from the insertion hole 61 and popping out during torque testing, thus preventing damage. Next, another hinge plate is fixed by a fixing device. At this time, the torque measuring instrument is started to drive the connecting plate 12 to rotate. When the connecting plate 12 rotates, it drives the fixing device to rotate, thereby testing the torque between the hinge plate and the hinge connecting piece.

[0021] like Figure 1 and Figure 2 As shown, the extrusion device includes an L-shaped fixing plate 41 fixedly connected to the front positioning block 4. The outer wall of the L-shaped fixing plate 41 is threaded with a wing screw 10. One side of the front positioning block 4 is provided with a spring-loaded vertical plate 11. One side of the vertical plate 11 is fixedly connected with a plastic extrusion plate 111 that passes through the front positioning block 4. One end of the plastic extrusion plate 111 abuts against the hinge 7, and one side of the vertical plate 11 abuts against one end of the wing screw 10.

[0022] When the extrusion device is in use, first turn the wing screw 10 so that the wing screw 10 moves along the inner wall of the front positioning block 4, thereby pushing the vertical plate 11 to move. The movement of the vertical plate 11 drives the plastic extrusion plate 111 to move, thereby causing the plastic extrusion plate 111 to extrude the connector of the hinge 7, so that the insert plate of the hinge 7 is inserted into the insertion hole 61 to prevent the hinge 7 from popping out during torque measurement. At the same time, the plastic extrusion plate 111 can prevent damage to the connector of the hinge 7 when extruding it.

[0023] like Figure 2 As shown, two mounting holes are provided on one side of the front positioning block 4. Springs 14 are fixedly connected inside the mounting holes, and one end of each spring 14 is fixedly connected to one side of the vertical plate 11.

[0024] When the wing screw 10 is rotated by the spring 14, the vertical plate 11 can retract, making room to place the undetected hinge 7.

[0025] like Figure 1 As shown, a detachable rotary drive block 9 is provided above the connecting plate 12. A through hole is provided at the top of the rotary drive block 9. A fixing screw 8 is inserted inside the rotary drive block 9. One end of the fixing screw 8 is inserted into the through groove of the hinge 7 chain plate. A nut 81 is provided on one side of the rotary drive block 9 and is threadedly connected to the top of the fixing screw 8.

[0026] When fixing the hinge plate that is not fixed by hinge 7, firstly, when hinge 7 is turned 90 degrees, insert fixing screw 8 into the through groove of hinge plate. One end of fixing screw 8 passes through the through hole at the top of rotary drive block 9 and is threaded to nut 81, so that hinge plate and rotary drive block 9 are fixed.

[0027] like Figure 1 As shown, the bottom of the rotary drive block 9 is provided with a connecting screw 13 that is threadedly connected to the connecting plate 12. The connecting screw 13 facilitates the installation and disassembly of the connecting plate 12 and the rotary drive block 9.

[0028] like Figure 2 and Figure 4 As shown, a protrusion 31 is fixedly connected to the bottom surface of the connecting block 3, and a square groove 17 adapted to the protrusion 31 is provided above the fixing ring 1.

[0029] The protrusion 31 is inserted into the square groove 17 of the fixing ring 1 to facilitate the fixing of the fixing ring 1.

[0030] like Figure 1As shown, a fixing post 15 that passes through the rotating collar 2 is fixedly connected to the bottom surface of the fixing ring 1. A fixing circular plate 16 that is fixedly connected to the bottom surface is fixedly connected to the bottom end of the fixing post 15. The fixing post 15 is fixed by the fixing circular plate 16.

[0031] The fixed ring 1 is fixed by the fixed column 15, so that the fixed ring 1 does not move when the hinge 7 is measured. The torque measuring machine drives the rotary drive block 9 to rotate, and the rotary drive block 9 drives the fixed screw 8 to rotate, which in turn drives the hinge plate on one side of the hinge 7 to rotate, thereby measuring the torque of the hinge 7.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
