[0002] During the transportation, storage or testing of flexible test samples (such as soft materials, thin films, flexible electronic devices, etc.), they are prone to deformation, damage or performance failure due to external force extrusion, vibration or environmental changes (such as temperature, humidity). Traditional rigid fixing devices (such as foams, plastic boxes) cannot adapt to their deformation characteristics, and are prone to fixing failure or sample damage.

[0003] Through retrieval, Chinese Patent Publication No. CN220167963U discloses a flexible protective net, which relates to the technical field of protective nets.

Four fastening nuts one are correspondingly threadedly connected to the four transverse sliders and abut against one side surface of the transverse slide rail

[0012] Preferably, a longitudinal slide rail is fixedly connected between two longitudinally flush transverse sliders. The number of the longitudinal slide rails is two. Two longitudinal sliders are longitudinally slidably connected to each of the two longitudinal slide rails. Four fastening nuts two are correspondingly threadedly connected to the four longitudinal sliders and abut against one side surface of the longitudinal slide rail.

[0013] Preferably, threaded holes are correspondingly formed at the tops of the four longitudinal sliders. A vertical lead screw is rotatably connected to each of the threaded holes

[0014] Preferably, threaded holes are vertically and penetratingly formed in both the upper and lower sliding block one and the upper and lower sliding block two. The vertical lead screw is threadedly rotated into the upper and lower sliding block one and the upper and lower sliding block two. A positive threaded hole and a reverse threaded hole are respectively formed in the two longitudinally arranged upper and lower sliding block one.

[0018] Preferably, a height tightening nut is threadedly connected to the four upper and lower sliding blocks one and abuts against the circumferential outer wall of the vertical lead screw.

[0019] A usage method of a flexible test sample adjustable packaging and fixing device, the usage method includes the following steps:

[0020] First step, loosen the fastening nut one so that it does not abut against one side of the horizontal slide rail. At this time, the four horizontal sliding blocks can be horizontally slid on the two horizontal slide rails. After sliding to a suitable position, screw the fastening nut one into the horizontal sliding block so that it abuts against one side of the horizontal slide rail;

[0021] Second step, loosen the fastening nut two so that it does not abut against one side of the vertical slide rail. At this time, the four vertical sliding blocks can be vertically slid on the two vertical slide rails. After sliding to a suitable position, screw the fastening nut two into the vertical sliding block so that it abuts against one side of the vertical slide rail;

[0022] Third step, the sliding of the horizontal sliding block can adjust the length of the device, and the sliding of the vertical sliding block can adjust the width of the device. With the adjustment of the length and width of the device, the three-dimensional adjustment mechanism and the fastening mechanism need to be adjusted correspondingly. The adjustment process is as follows:

[0023] S: When the horizontal sliding block slides on the horizontal slide rail, it is necessary to synchronously loosen the fastening nut four so that it does not abut against the circumferential outer wall of the horizontal lead screw. The central sliding of the horizontal slide rail will cause the upper and lower sliding blocks two on the two horizontal lead screws in the horizontal direction to approach each other centrally. At this time, the upper and lower sliding blocks two will approach each other centrally on the left- and right-handed threads of the horizontal lead screw. The central approach of the upper and lower sliding blocks two will cause the upper and lower sliding blocks one, the vertical lead screw and the fastening nut three to approach each other synchronously. At this time, the mutually approaching vertical lead screws will loosen the flexible packaging bags at both ends thereof. At this time, it is necessary to pull the tie strap body toward the opposite sides of the two vertical lead screws and lock it with a tie strap buckle at the same time;

[0024] S: When the vertical sliding block slides centrally on the vertical slide rail, it is necessary to synchronously loosen the fastening nut three so that it does not abut against the circumferential outer wall of the vertical lead screw. The central sliding of the vertical sliding block will cause the fastening nuts three on the two vertical lead screws in the horizontal direction to approach each other centrally. At this time, the fastening nuts three will approach each other centrally on the left- and right-handed threads of the vertical lead screw. The central approach of the fastening nuts three will cause the upper and lower sliding blocks two, the horizontal lead screw and the fastening nut four to approach each other synchronously. At this time, the mutually approaching horizontal lead screws will loosen the flexible packaging bags at both ends thereof. At this time, it is necessary to pull the tie strap body toward the opposite sides of the two vertical lead screws and lock it with a tie strap buckle at the same time.

[0025] Step 4: If it is necessary to adjust the height of the flexible net, only loosen the height fastening nut so that it does not press against the circumferential outer wall of the vertical screw rod. At this time, lower the flexible net. The rotation of the vertical screw rod will be caused by the downward movement of the upper and lower sliding blocks 1 and the upper and lower sliding blocks 2. After lowering to an appropriate position, tighten the height fastening nut so that it presses against the circumferential outer wall of the vertical screw rod to prevent the flexible net from falling.

[0026] The present invention has the following beneficial effects:

[0027] 1. In the present invention, by loosening fastening nut 1 and fastening nut 2, the lateral distance of the four lateral sliding blocks can be adjusted centrally, and the longitudinal distance of the four longitudinal sliding blocks can be adjusted centrally. By sequentially tightening fastening nut 1 and fastening nut 2, the advantages of a device fitting that can be connected and fixed and freely adjusted are achieved.

[0028] 2. In the present invention, by loosening fastening nut 4 and fastening nut 3, the upper and lower sliding block 2 can achieve the advantage of lateral central sliding, and the upper and lower sliding block 1 can achieve the advantage of longitudinal central sliding. Just sequentially tighten fastening nut 4 and fastening nut 3. Loosening the height fastening nut can enable the overall height of the flexible net to be adjusted up and down on the four vertical screw rods, thus achieving the advantage of quickly adjusting the three-axis space distance.

[0029] 3. In the present invention, due to the different locking positions of the cable tie lock on the cable tie body, the flexible packaging bag can adapt to the space transformed by the longitudinal screw rod and the lateral screw rod after expansion and contraction. The adjusted flexible net is suitable for packaging flexible items of different sizes and volumes, making its accommodation range wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In this embodiment, as Figure 2 and Figure 3 shown, height fastening nuts 90 are threadedly connected to the four upper and lower sliding blocks 9 and abut against the circumferential outer wall of the vertical lead screw 8.

[0048] A usage method of a flexible test sample adjustable packaging and fixing device, the usage method includes the following steps:

[0049] First step, loosen the first fastening nut 4 so that it does not abut against one side of the horizontal slide rail 2. At this time, the four horizontal sliders 3 can be slid horizontally on the two horizontal slide rails 2. After sliding to a suitable position, screw the first fastening nut 4 into the horizontal slider 3 so that it abuts against one side of the horizontal slide rail 2;

[0050] Second step, loosen the second fastening nut 7 so that it does not abut against one side of the longitudinal slide rail 5. At this time, the four longitudinal sliders 6 can be slid longitudinally on the two longitudinal slide rails 5. After sliding to a suitable position, screw the second fastening nut 7 into the longitudinal slider 6 so that it abuts against one side of the longitudinal slide rail 5;

[0051] Third step, the sliding of the horizontal slider 3 can adjust the length of the device, and the sliding of the longitudinal slider 6 can adjust the width of the device. With the adjustment of the length and width of the device, the three-dimensional adjustment mechanism and the fastening mechanism need to be adjusted correspondingly. The adjustment process is as follows:

[0052] S1: When the horizontal slider 3 slides on the horizontal slide rail 2, it is necessary to synchronously loosen the fourth fastening nut 14 so that it does not abut against the circumferential outer wall of the horizontal lead screw 13. The central sliding of the horizontal slide rail 2 will make the upper and lower sliding blocks 12 on the two horizontal lead screws 13 in the horizontal direction move closer to the center. At this time, the upper and lower sliding blocks 12 will move closer to the center on the forward and reverse threads of the horizontal lead screw 13. The closer movement of the upper and lower sliding blocks 12 will make the upper and lower sliding blocks 9, the longitudinal lead screw 10 and the third fastening nut 11 move closer synchronously. At this time, the longitudinal lead screws 10 that are close to each other will loosen the flexible packaging bags 15 at both ends. At this time, it is necessary to pull the tie strap bodies 150 towards the opposite sides of the two longitudinal lead screws 10 and lock them with the tie strap lock 16 at the same time;

[0053] S2: The longitudinal slider 6 slides centered on the longitudinal slide rail 5. It is necessary to loosen the third fastening nut 11 synchronously so that it does not abut against the circumferential outer wall of the longitudinal lead screw 10. The centered sliding of the longitudinal slider 6 will cause the third fastening nuts 11 on the two longitudinal lead screws 10 in the transverse direction to approach each other centered. At this time, the third fastening nuts 11 will move centered and approach on the left-handed and right-handed threads of the longitudinal lead screw 10. The centered approach of the third fastening nuts 11 will cause the upper and lower sliding blocks II 12, the transverse lead screw 13 and the fourth fastening nut 14 to approach synchronously. At this time, the transverse lead screws 13 approaching each other will loosen the flexible packaging bags 15 at both ends thereof. At this time, it is necessary to pull the tie tape body 150 towards the opposite sides of the two longitudinal lead screws 10, and lock it with the tie tape buckle 16 at the same time.

[0054] Step 4: If it is necessary to adjust the height of the flexible net, only loosen the height fastening nut 90 so that it does not abut against the circumferential outer wall of the vertical lead screw 8. At this time, lower the flexible net. The rotation of the vertical lead screw 8 will be caused by the descent of the upper and lower sliding blocks I 9 and the upper and lower sliding blocks II 12. After descending to an appropriate position, tighten the height fastening nut 90 so that it abuts against the circumferential outer wall of the vertical lead screw 8 to prevent the flexible net from falling.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

At this time, the four transverse slide blocks (3) can be slid transversely on the two transverse slide rails (2). After sliding to a suitable position, the fastening nut 1 (4) can be screwed into the transverse slide block (3) so that it presses against one side of the transverse slide rail (2). The second step is to loosen the second fastening nut (7) so that it does not abut against one side of the longitudinal slide rail (5).

After sliding to a suitable position, the second fastening nut (7) is screwed into the longitudinal slide block (6) so that it abuts against one side of the longitudinal slide rail (5). In the third step, the sliding of the transverse slider (3) can adjust the length of the device, and the sliding of the longitudinal slider (6) can adjust the width of the device. As the length and width of the device are adjusted, the three-dimensional adjustment mechanism and the fastening mechanism need to be adjusted accordingly. The adjustment process is as follows: S1: The transverse slider (3) slides on the transverse slide rail (2), and the fastening nut four (14) needs to be loosened synchronously so that it does not press against the circumferential outer wall of the transverse screw rod (13). The transverse slide rail (2) slides in the center so that the upper and lower sliding blocks two (12) on the two transverse transverse screw rods (13) are centered and close to each other. At this time, the upper and lower sliding blocks two (12) will move in the center on the positive and negative threads of the transverse screw rod (13). The centering and approaching of the upper and lower sliding blocks two (12) will make the upper and lower sliding blocks one (9), the longitudinal screw rod (10) and the fastening nut three (11) approach synchronously. At this time, the longitudinal screw rods (10) approaching each other will loosen the flexible packaging bags (15) at both ends. At this time, it is necessary to pull the cable tie body (150) toward the opposite sides of the two longitudinal screw rods (10) and lock it with the cable tie buckle (16). S2: The longitudinal slider (6) slides in the center on the longitudinal slide rail (5), and the fastening nut three (11) needs to be loosened synchronously so that it does not press against the circumferential outer wall of the longitudinal screw rod (10). The longitudinal slider (6) slides in the center so that the fastening nuts three (11) on the two transverse longitudinal screw rods (10) are centered and close to each other. At this time, the fastening nut three (11) will move in the center on the positive and negative threads of the longitudinal screw rod (10). The centering and approaching of the fastening nut three (11) will cause the upper and lower sliding blocks two (12), the transverse screw rod (13) and the fastening nut four (14) to approach synchronously. At this time, the transverse screw rods (13) approaching each other will loosen the flexible packaging bags (15) at both ends. At this time, it is necessary to pull the cable tie body (150) toward the opposite sides of the two longitudinal screw rods (10) and lock it with the cable tie buckle (16). In the fourth step, if the height of the flexible net needs to be adjusted, it is only necessary to loosen the height fastening nut (90) so that it does not abut against the circumferential outer wall of the vertical screw rod (8).
