The anti-static torsion performance is an essential inspection item for the type inspection of door leaf products, and particularly is of great importance to the anti-static torsion performance of vertical hinged doors and rotary door products. The performance detection scheme is based on the standard GB/T29530 (determination of static twist resistance of vertical hinged doors and revolving doors), please refer to FIGS. 1 and 2, and the principle is as follows: the door leaf 1 is opened to a position of 90 degrees plus or minus 5 degrees relative to the plane of the door frame, no constraint exists in the vertical direction, and the door leaf 1 is fixed on a fixed point 16 which is 50mm away from each side of the door leaf 1 at the upper corner of one side of the door leaf 1 with a lock (namely, the free side of the door leaf 1 opposite to the hinged side), and the hinge rotating shaft is kept to be motionless. The position corresponding to the arrow above the door leaf 1 in fig. 1 represents the above fixing point 16. At the lower corner of the free side of the door leaf 1, at a loading point 17 of 50mm from each side of the door leaf 1, a horizontal load of 200N is applied perpendicular to the plane of the door leaf 1, which load is removed after 60 s. After 60s again, the initial displacement at the lower corner loading point 17 of the door leaf 1 is measured. And then applying a static test load 300s on the same loading point 17, measuring the maximum deformation at the loading point 17 during loading, and measuring a displacement value at the loading point 17 of the door leaf 1 after removing the load 180 s. The position corresponding to the arrow below the door leaf 1 in fig. 1 represents the above loading point 17.
Based on the above principle, the present embodiment provides an apparatus for measuring the anti-static torsion performance of a door leaf, referring to fig. 3 and 4, including a mounting frame 12 for mounting the door leaf 1, a loading unit for applying a load to the door leaf 1, a measuring unit 4 for measuring the deformation amount of the door leaf 1, a controller 10, and a display 11.

The controller 10 generally controls the application time of the load, and adjusts the magnitude of the load received by the door leaf 1 in cooperation with the counterweight 7. While the display 11 generally needs to display the time when the parameter is loaded, it is of course also possible to display the magnitude of the load or other relevant parameters of the load.
The opening position of the door leaf 1 can be selected to be 90 degrees plus or minus 5 degrees with the plane of the installation frame 12, and any other suitable angle can be selected.

In fig. 3, the mounting frame 12 is rectangular. It is needless to say that the shape of the mounting frame 12 corresponds to the shape of the door leaf 1 to be tested. For example, when the door leaves 1 to be tested are all non-rectangular in shape, the mounting frame 12 provided at this time should also be non-rectangular in shape corresponding to the shape of the door leaves 1. Correspondingly, the mounting position of the clamping device 2 and the mounting position of the loading unit can also be adjusted accordingly.
In fig. 3, the rectangular mounting frame 12 includes an upper frame 121, a lower frame 122, and first and second side frames.

The movable second side frame 125 is disposed between the left frame 123 and the right frame 124 and is fixed with respect to the right frame 124 by the clamping member 15. In this case, the left side of the door leaf 1 is the hinge side, and the right side of the door leaf 1 is the free side.
Of course, the mounting manner of the second side frame 125 is not limited to the above example, as long as it can be moved and fixed with respect to the upper frame 121 and the lower frame 122.
In this embodiment, the projecting arm 13 is fixed to the mounting frame 12, and the jig 2 is provided on the projecting arm 13. And preferably, but not necessarily, the projecting arm 13 is perpendicular to the plane of the mounting frame 12. This may facilitate the fixture 2 to secure the free side. Furthermore, in order to accommodate different sizes of door leaves 1, it is preferred that the clamp 2 is movable and fixed along the projecting arms 13.
In fig. 3, the projecting arm 13 is fixed to the upper rim 121 of the mounting frame 12 so that the clip 2 grips the upper end of the free side. At this time, the loading unit is connected to the lower end of the free side to apply a load to the lower end of the free side of the door leaf 1. Of course, the extension arm 13 may also be fixed to the lower rim 122 of the mounting frame 12 so that the clamp 2 clamps the lower end of the free side, and the loading unit loads the upper end of the free side. Alternatively, the extension arm 13 may be mounted at other positions of the mounting frame 12, corresponding to other forms of the clip 2.
In order to secure the structural strength of the extension arm 13, it is preferable that the extension arm 13 is connected to the mounting frame 12 via a reinforcing rib 14.
Further, the present embodiment provides a fixture 2, please refer to fig. 5 to 7, including a U-shaped body 201, and a bolt 202 disposed on the U-shaped body 201, wherein the free side is clamped in the opening of the U-shaped body 201 by tightening the bolt 202. Of course, such a fixture 2 does not constitute a limitation of the fixture 2 in the present application.
Referring to fig. 4, the loading unit of the present embodiment includes a counterweight 7, a fixed pulley 5 assembly, and a pull rope 8, wherein one end of the pull rope 8 is connected with the counterweight 7, the other end is connected with the door leaf 1, and the fixed pulley 5 assembly satisfies: after the pull rope 8 passes around the fixed pulley 5 of the fixed pulley 5 assembly, the counterweight 7 applies a horizontal pulling force to the door leaf 1 through the pull rope 8. By means of the counterweight 7 and fixed pulley 5 assembly, the magnitude of the load applied to the door leaf 1 can be precisely controlled. And, this kind of loading unit cooperates with the measuring unit 4 mentioned later, the accuracy of the measuring unit 4 can be ensured.
In fig. 4, the fixed pulley 5 assembly comprises two fixed pulleys 5, and the stress direction of the pull rope 8 is changed through the two fixed pulleys 5. Of course, the number and distribution of the fixed pulleys 5 are not limited by the drawings.
The weight 7 is preferably, but not necessarily, a weight, so that the load applied to the door leaf 1 can be clarified by the weight of the weight. Also, the pull cord 8 is preferably, but not necessarily, a steel wire.
In order to adjust the amount of load to which the door leaf 1 is subjected, a support 9 may be provided at the bottom end of the counterweight 7. The support 9 may be in the form of a cylinder, a hydraulic cylinder or a motor, among others. When the support 9 is a cylinder, it can adjust the loading state and loading time of the loading unit. Wherein, before loading, the piston of the cylinder stretches outwards and jacks up the weight tray, and when loading, the piston of the cylinder is recovered, so that the weight falls down and applies load to the door leaf 1.
Referring to fig. 4, in order to accommodate door leaves 1 of different sizes, the fixed pulley 5 assembly of the present embodiment further includes a first mounting seat 6 for mounting the fixed pulley 5, and the first mounting seat 6 is height-adjustable. In fig. 4, when there are two fixed pulleys 5, only the mounting height of the left fixed pulley 5 needs to be adjusted, and therefore the first mount 6 is only required to mount the left fixed pulley 5. As for the fixed pulley 5 on the right side, it may be mounted on the same mounting table 3 as the cylinder simultaneously. When the mounting table 3 is sufficiently far from the door leaf 1 to be tested, the display 11 and the controller 10 may also be provided on the mounting table 3. Of course, in order to ensure the safety of the operator and realize the remote operation, the anti-static twist performance measuring apparatus of the door leaf is preferably additionally provided with the display 11 and the controller 10.
