When the door handle 7 rotates to the specified angle, the distance adjustment slide The block 23 rotates to the lower end of the turntable 21, and the turntable 21 starts to drive the cross bar 4 to rise through the distance-adjustable slide block 23. The cross bar 4 no longer presses down the door handle 7 through the fixed shaft 73, and the door handle 7 reverses the direction under the action of the torsion member. Rotate until the door handle 7 is reset (that is, the hand-grip end of the door handle 7 is level), and one rotation of the output shaft of the drive motor 2 counts as one. Repeat the above action. Each time the output shaft of the drive motor 2 rotates once, the door handle 7 is pressed down. It rotates to a specified angle once, and the crossbar 4 moves up and down repeatedly, causing the door handle 7 to rotate to a specified angle repeatedly, thereby realizing the fatigue strength quality inspection of the door handle 7, simulating door opening conditions, and thus accurately understanding Fatigue limit of door lock handle;

本发明中,通过锁止组件将调距滑块23锁止在调距滑槽22内不同的位置,能够改变横杆4移动过程中上下距离,调距滑块23距离转盘21轴线的距离越远,横杆4上下移动的距离越大,横杆4下压门把手7旋转的角度越大,反之则越小,能够实现模拟多种角度开门工况,进而能够准确地了解到门锁把手在不同工况下的疲劳极限。In the present invention, the distance-adjusting slider 23 is locked at different positions in the distance-adjusting chute 22 through the locking assembly, so that the up and down distance of the crossbar 4 during movement can be changed. The distance between the distance-adjusting slider 23 and the axis of the turntable 21 is longer. further, the greater the distance that the cross bar 4 moves up and down, the greater the rotation angle of the door handle 7 when the cross bar 4 presses down, and vice versa, the smaller the angle of the cross bar 4's downward movement. It is possible to simulate the door opening conditions at various angles, and thus the door lock handle can be accurately understood. Fatigue limits under different working conditions.

当需要模拟开门后立即松开门把手7时,转动松紧螺栓76使定位板74挤压门把手7,从而避免固定轴73脱离挡板11后,瞬间反转过程中,固定滑块71与门把手7脱离,导致挡板11无法继续通过固定轴73带动门把手7旋转,进而使门把手7质检受到影响,定位弹簧75能够通过定位板74对松紧螺栓76施加力,确保松紧螺栓76和定位板74之间的螺纹紧密贴合,从而避免松紧螺栓76转动,影响固定滑块71与门把手7的固定;定位板74向门把手7移动时,阻拦条77也向门把手7底部移动,当两者存在重合区域时,阻拦条77则能够进一步避免固定滑块71与门把手7脱离,导致挡板11无法继续通过固定轴73带动门把手7旋转,进而使门把手7质检受到影响。When it is necessary to release the door handle 7 immediately after simulating opening the door, turn the elastic bolt 76 to make the positioning plate 74 squeeze the door handle 7, thereby preventing the fixed shaft 73 from being separated from the baffle 11 and the fixed slider 71 and the door being instantly reversed. The handle 7 is detached, causing the baffle 11 to be unable to continue to drive the door handle 7 to rotate through the fixed shaft 73, thereby affecting the quality inspection of the door handle 7. The positioning spring 75 can exert force on the elastic bolt 76 through the positioning plate 74 to ensure that the elastic bolt 76 and The threads between the positioning plates 74 are in close contact, thereby preventing the elastic bolt 76 from rotating and affecting the fixation of the fixed slider 71 and the door handle 7; when the positioning plate 74 moves toward the door handle 7, the blocking bar 77 also moves toward the bottom of the door handle 7 , when there is an overlapping area between the two, the blocking strip 77 can further prevent the fixed slider 71 from being separated from the door handle 7 , causing the baffle 11 to be unable to continue to drive the door handle 7 to rotate through the fixed shaft 73 , thereby affecting the quality inspection of the door handle 7 Influence.

作为本发明的进一步方案,扭转构件包括外壳61,外壳61滑动连接有导杆62,导杆62内侧端固定连接有复位滑块63,复位滑块63与导杆62之间固定连接有复位弹簧64,复位滑块63内滑动连接有固定杆65,固定杆65固定连接有转板66,转板66固定连接有与外壳61转动连接的插套67,插套67开设有方形结构的插槽68;As a further solution of the present invention, the torsion member includes a shell 61.

The insert sleeve 67 is provided with a square-structured slot. 68;

使用时,门把手7插入插槽68内,由于插槽68方形结构门把手7转动时,插套67能够随之转动,插套67转动时,转板66转动并且带动固定杆65沿插套67轴线转动,固定杆65带动复位滑块63移动,复位滑块63带动导杆62移动并且压缩复位弹簧64,当横杆4上升时,复位弹簧64推动复位滑块63移动,复位滑块63带动固定杆65、转板66反转,插套67通过插槽68将门把手7复位,此过程中由复位弹簧64推复位滑块63,复位滑块63通过固定杆65、转板66和插套67对门把手7施加扭力,当复位滑块63移动至外壳61侧壁时,门把手7复位,由于复位滑块63接触外壳61侧壁无法继续移动,避免门把手7继续向上转动,既能够对门把手7进行定位,也能够避免门把手7反向转动,导致门把手7做无用动作,增加门把手7的损耗,影响门把手7质检数据;When in use, the door handle 7 is inserted into the slot 68. Due to the square structure of the slot 68, when the door handle 7 rotates, the insert sleeve 67 can rotate accordingly. When the insert sleeve 67 rotates, the rotating plate 66 rotates and drives the fixing rod 65 along the insert sleeve. 67 axis rotates, the fixed rod 65 drives the reset slider 63 to move, the reset slider 63 drives the guide rod 62 to move and compresses the return spring 64. When the crossbar 4 rises, the return spring 64 pushes the reset slider 63 to move, and the reset slider 63 The fixed rod 65 and rotating plate 66 are driven to reverse, and the insert sleeve 67 resets the door handle 7 through the slot 68. During this process, the return spring 64 pushes the reset slider 63, and the reset slider 63 passes through the fixed rod 65, the rotating plate 66 and the inserting sleeve 67. The sleeve 67 exerts torque on the door handle 7. When the reset slider 63 moves to the side wall of the housing 61, the door handle 7 is reset. Since the reset slider 63 contacts the side wall of the housing 61 and cannot continue to move, it prevents the door handle 7 from continuing to rotate upward. Positioning the door handle 7 can also prevent the door handle 7 from rotating in the opposite direction, causing the door handle 7 to make useless movements, increasing the loss of the door handle 7 and affecting the quality inspection data of the door handle 7;
