DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 5, a design exhibition stand load-bearing test device based on visual communication, including a support mechanism arranged on a test bench 1 for placing the exhibition stand and a load-bearing test block 7 arranged above the test bench 1, the support mechanism including a hydraulic telescopic rod 2, a mounting plate 3 and a support seat 4; a through hole connected to the upper and lower sides and adapted to the support seat 4 is opened inside the test bench 1, the hydraulic telescopic rod 2 is fixedly mounted on the lower surface of the test bench 1, the upper surface of the mounting plate 3 is fixed to the output end of the hydraulic telescopic rod 2, and the bottom side of the support seat 4 is fixed to the upper surface of the mounting plate 3. The introduction of the hydraulic telescopic rod 2 allows the height of the support seat 4 to be flexibly adjusted. This height adjustability not only facilitates adjusting the support seat 4 to an appropriate position above the test bench 1 to place the exhibition stand, but also can simulate the load-bearing conditions under different height conditions during the test process, thereby increasing the comprehensiveness and accuracy of the test.

[0027] In this embodiment, there are two supporting mechanisms, and the two supporting mechanisms are symmetrically arranged on the test bench 1, and a positioning rod plugged into the mounting plate 3 is installed inside the supporting legs on the test bench 1. There are two supporting mechanisms and they are symmetrically arranged on the test bench 1. This design helps to maintain stability during the test. At the same time, the positioning rod installed inside the supporting legs on the test bench 1 is plugged into the mounting plate 3, which further enhances the stability of the supporting mechanism and prevents shaking or displacement during the test. A pad is installed on the upper surface of the support seat 4.

[0028] In this embodiment, a driving mechanism 6 for driving the load-bearing test block 7 is arranged outside the test bench 1, and the driving mechanism 6 includes a driving turntable 601, a connecting rod 602, a driving motor 603, a transmission structure and an adjustment structure; wherein the adjustment structure is composed of an adjustment seat 607, a screw 608 and a first slider 609, the top end of the connecting rod 602 is hinged to the first slider 609, and the bottom end of the connecting rod 602 is fixedly installed with a universal ball joint 610 that is rotatably connected to the inside of the load-bearing test block 7. The adjustment seat 607 is fixedly installed on the front of the driving turntable 601, the screw 608 bearing is installed in the adjustment seat 607, and the first slider 609 is threadedly connected to the screw 608. A limit rod that runs through the inside of the first slider 609 is fixedly installed in the adjustment seat 607. One end of the screw 608 runs through the inside of the adjustment seat 607, and a knob is installed at the end of the screw 608. The design of the connecting rod 602 and the universal ball joint 610 enables the load-bearing test block 7 to move smoothly, reducing errors caused by unstable movement. Figure 3As shown, the transmission structure includes a meshing transmission gear 604 and a driven gear 605, wherein a rotating shaft 606 fixed to the back of the driving turntable 601 is fixedly installed inside the driven gear 605, and the transmission gear 604 is fixedly installed on the output shaft of the driving motor 603. The driving motor 603 can accurately control the rotation speed and direction of the driving turntable 601 through the transmission meshing of the transmission gear 604 and the driven gear 605, thereby ensuring the stability and accuracy of the load-bearing test block 7 during the reciprocating movement, thereby improving the accuracy of the test.

[0029] Furthermore, by adjusting the screw rod 608, the position of the first slider 609 can be changed, thereby adjusting the inclination angle or position of the connecting rod 602 and the bearing test block 7, so that the test device can adapt to booths of different shapes and sizes, thereby improving the flexibility of the test.

[0030] like Figure 4 As shown, a mounting seat 5 is provided above the test bench 1, a driving motor 603 is fixedly installed on the back of the mounting seat 5, a rotating shaft 606 passes through the inside of the mounting seat 5, and the rotating shaft 606 is connected to the internal bearing of the mounting seat 5. A limiting structure for guiding the load-bearing test block 7 is provided inside the mounting seat 5, and the limiting structure includes a guide block 611 and a guide rod 613. A guide groove 612 adapted to the guide block 611 is provided inside the mounting seat 5, and the guide block 611 extends to the inside of the guide groove 612. The guide rod 613 is fixedly installed between the upper and lower inner walls of the guide groove 612, and the guide rod 613 passes through the inside of the guide block 611. The stability and accuracy of the load-bearing test block 7 during movement are ensured. The sliding of the guide block 611 in the guide groove 612 and the guiding effect of the guide rod 613 enable the load-bearing test block 7 to move along a predetermined trajectory. As shown Figure 4 and Figure 5 As shown, a buffer spring 614 is fixedly installed between the guide block 611 and the inner top wall of the guide groove 612, and the buffer spring 614 surrounds the outer surface of the guide rod 613. The setting of the buffer spring 614 plays a role of buffering and shock absorption. When the load-bearing test block 7 is impacted, the buffer spring 614 can absorb part of the impact force to protect the test device and the booth from damage.

[0031] To increase the test coverage, such as Figure 1As shown, a slide groove 10 connected to the upper surface is provided inside the test bench 1, and a second slider 9 is slidably installed in the slide groove 10. The design of the slide groove 10, the slide rail 8 and the second slider 9 provided inside the test bench 1 enables the mounting seat 5 and the driving mechanism 6 to move in the horizontal direction. This design not only increases the scope of the test, but also enables the test device to adapt to booths of different sizes. The slide rail 8 is bolted to the upper surface of the second slider 9, and the mounting seat 5 is slidably installed on the slide rail 8. A first plug-in rod plugged with the second slider 9 is installed on the test bench 1; a second plug-in rod for positioning the mounting seat 5 is installed in the slide rail 8. A control device is installed on the back of the test bench 1. The provision of the first plug-in rod and the second plug-in rod ensures the stability and accuracy of the mounting seat 5 and the slide rail 8 during movement, and prevents errors caused by shaking or displacement.

[0032] The working principle of the above embodiment is:

At this time, there is a distance between the panel and the test bench 1. Then start the drive motor 603, and drive the drive turntable 601 to rotate through the transmission gear 604 and the driven gear 605. The rotation of the drive turntable 601 drives the load-bearing test block 7 to move back and forth through the connecting rod 602 to realize the load-bearing test of the visual communication design booth panel. Then, the support seat 4 is flush with the test bench 1 through the hydraulic telescopic rod 2. At this time, the visual communication design is in contact with the test bench 1, and the load-bearing test block 7 is reciprocated by the driving mechanism 6 again to realize the load-bearing test of the visual communication design booth panel again, and achieve different testing effects.
