[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In the description of the embodiments of the present invention, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention proposes a luggage shoulder strap anti-stretching device, including a testing device 1, wherein the testing device 1 includes a limit block 11, a first sliding column 12, a sliding platform 13, a control base block 14, a fixed connecting rod 15, a protective seat 16, a second sliding column 17, a workbench 18, an information receiver 19, a rotating base block 110, a ventilation valve 111, a first clamp 112, an upper limit platform 113 and a connecting strip 114.

[0029] In the embodiment of the present invention, a first sliding column 12 is provided inside the limit block 11, and the first sliding column 12 passes through the inside of the sliding platform 13. The sliding platform 13 can slide back and forth along the first sliding column 12. A second sliding column 17 is provided on the upper part of the sliding platform 13, and the second sliding column 17 passes through the inside of the working platform 18. A rotating base block 110 is provided on one side of the working platform 18, and the rotating base block 110 is movably connected to the outside of the working platform 18. A ventilation valve 111 is provided on the upper part of the rotating base block 110, and the ventilation valve 111 is externally connected to compressed gas. The ventilation valve 111 can drive the rotation of the rotating base block 110. A first clamping hand 112 is provided at the front end of the rotating base block 110, and the first clamping hand 112 can clamp the shoulder strap to be tested. An information receiver 19 is provided on the other side of the working platform 18, and the information receiver 19 is used to receive the force applied by the first clamping hand 112 to the shoulder strap and analyze the force condition of the shoulder strap.

[0030] An upper limit platform 113 is provided on the upper part of the workbench 18, and the upper limit platform 113 can limit the movement of the workbench 18. A plurality of control base blocks 14 are provided on the side of the sliding platform 13. A protective seat 16 is provided inside the control base block 14, and a fixed link 15 is provided between the protective seat 16.

A connecting strip 114 is provided on one side of the fixed link 15, and the other end of the connecting strip 114 is fixedly connected to the sliding platform 13. When the fixed link 15 moves, the connecting strip 114 can be driven to move, and then the sliding platform 13 can be driven to move on the first sliding column 12. The movement of the sliding platform 13 can eventually drive the first clamping hand 112 to move. After the first clamping hand 112 clamps the shoulder strap, the sliding platform 13 starts to move, and then the first clamping hand 112 moves. At this time, the shoulder strap fixed inside the first clamping hand 112 will be stretched laterally, making the test of the shoulder strap more detailed.

[0031] First, the two ends of the shoulder strap will be fixed between the lower fixed clamp 28 and the upper fixed clamp 29, and then the lower fixed clamp 28 will move downward to straighten the shoulder strap to be tested, and then the workbench 18 will control the opening and closing of the first clamp 112, and the first clamp 112 will clamp the shoulder strap to be tested, and then the base block 14 will be controlled to drive the connecting strip 114 to move, thereby driving the movement of the first clamp 112. The movement of the first clamp 112 will drive the shoulder strap to be stretched laterally, and by driving the ventilation valve 111 set on the upper part of the rotating base block 110, the rotating base block 110 can be rotated, and then the first clamp 112 can be rotated. Finally, the tested shoulder strap can be stretched not only in the vertical and horizontal directions, but also the performance of the shoulder strap in a twisted state can be tested.

[0032] Compared with traditional detection devices, the present invention can not only test the detection status of the shoulder strap in the vertical direction, but also test the shoulder strap in the lateral direction and when the shoulder strap is rotated. After testing in a variety of different ways, the final test result can be made more accurate.
