[0002] Driven by economic globalization, economic exchanges among countries around the world are frequent, and the scale of international trade is also constantly expanding. As an activity for displaying products and technologies, expanding channels, and promoting sales, exhibitions are becoming more and more frequent.

[0003] Traditional vertical fixing structures generally use flange plates. The flange plates are fixed by opening holes at the bottom, and then vertical rods are welded to the top of the flange plates. However, it is very difficult to ensure perpendicularity between the flange plates and the vertical rods during welding. Therefore, we propose a device with a bayonet structure for fixing a vertical rod to ensure perpendicularity. Summary of the Invention

The insertion section passes through the second through hole and extends into the first through hole, and both the first through hole and the second through hole are adapted to the structure of the insertion section.

[0011] According to the technical solution provided by the embodiment of the present application, a third through hole is formed in the sleeve in the first direction, and the third through hole is adapted to the first stepped stage. One end of the rod body close to the first stepped stage abuts against the top of the contact piece.

[0012] According to the technical solution provided by the embodiment of the present application, a groove is formed at the bottom of the base, which is communicated with the first through hole and is used to accommodate the fastener. The first stepped stage sequentially passes through the third through hole, the second through hole and the first through hole and extends into the groove, and is engaged with the fastener, and the fastener is connected to the groove through a mounting member.

[0031] The base structure also includes a sleeve 5, such as Figure 4 As shown, the sleeve 5 includes an abutment sheet 6 and an insertion section 7 fixedly connected in a first direction, the abutment sheet 6 is located at the top of the insertion section 7, the insertion section 7 passes through the second through hole 4 and extends into the first through hole 2, and the insertion section 7 is adapted to the first through hole 2, and optionally, the cross section of the insertion section 7 is a D-shaped structure, and the bottom of the abutment sheet 6 abuts against the top of the decorative plate 3;

[0032] Further, a third through hole 8 is formed in the sleeve 5 and runs through it in the first direction. The third through hole 8 runs through the abutting piece 6 and the insertion section 7. Optionally, the third through hole 8 has a D-shaped structure.

[0033] As Figure 3 shown, there is a support rod whose length direction extends along the first direction. The support rod includes a support rod body 9. The bottom of the support rod body 9 has a first stepped stage 10. The projected area of the first stepped stage 10 in the first direction is smaller than the projected area of the support rod in the first direction. The first stepped stage 10 runs through the third through hole 8 and the first through hole 2 and extends below the base 1. And one end of the support rod body 9 close to the first stepped stage 10 abuts against the top of the abutting piece 6;

[0034] Further, as Figure 5 shown, a groove 11 is formed in the bottom of the base 1 corresponding to the first through hole 2. The groove 11 is communicated with the first through hole 2. The first stepped stage 10 extends into the groove 11. A clamping groove 12 is circumferentially formed on the first stepped stage 10;

[0035] Further, it further includes a fastener 13. As Figure 6 shown, it has a U-shaped structure and is installed in the groove 11 through three mounting parts 14. The fastener 13 has a clamping part which is clamped with the clamping groove 12.

[0036] It further includes a product tray 15 which is arranged on the top of the support rod;

[0037] Specifically, the product tray 15 has a lifting part 16 and a connecting part 17 which are fixedly connected in the first direction. The lifting part 16 is located on the top of the connecting part 17. It has a U-shaped structure and has a lifting space for placing products. Optionally, the connecting part 17 is located at the middle position of the bottom of the lifting part 16;

[0038] Further, as Figure 7 and Figure 8 shown, a receiving groove 18 is formed in the bottom of the connecting part 17. A through hole 19 is formed in the top of the lifting part 16. The receiving groove 18 is communicated with the through hole 19. Optionally, the cross section of the receiving groove 18 has a D-shaped structure;

[0039] Further, the top of the support rod body 9 has a second stepped stage 20 which is adapted to the receiving groove 18. The second stepped stage 20 extends into the receiving groove 18. Optionally, the receiving groove 18 has a D-shaped structure;

[0040] Further, the inside of the support rod is hollow to form a wire threading space. The two ends of the wire threading space in the first direction are respectively communicated with the two ends of the support rod, and run through the first stepped stage 10 and the second stepped stage 20 along the first direction respectively;

[0041] As Figure 3 and Figure 5As shown, a notch 21 is formed in the side wall of the first stage 10. The notch 21 is in communication with the wire threading space and is also in communication with the groove 11.

[0042] The top of the wire threading space is in communication with the receiving groove 18.

[0043] Thus, the power supply data line 22 can be arranged in the wire threading space. One end of the power supply data line 22 has a charging plug 23, which can pass through the receiving groove 18 and the through port 19 and extend above the lifting part 16 to charge the product 24 placed in the lifting space. The other end of the power supply data line 22 can extend from the notch 21 into the groove 11 and extend out of the groove 11 to connect to an external socket.

[0044] It should be noted that pads are provided at the four corners of the bottom of the base 1 to maintain the stability of the base 1.

[0045] Working principle: During installation, first connect the decorative plate 3 and the base 1. Then, insert the insertion section 7 of the sleeve 5 through the second through hole 4 and extend it into the first through hole 2. At this time, the abutting piece 6 can abut against the top of the decorative plate 3. Then insert the support rod, and make the first stage 10 pass through the sleeve 5 and extend into the groove 11. The D-shaped first stage 10 is adapted to the D-shaped third through hole 8, which can prevent the support rod from rotating. Then place the fastener 13 in the groove 11, make the clamping part of the fastener 13 engage with the clamping groove 12, and make the notch 21 face the opening of the U-shaped fastener 13 to facilitate the power supply data line 22 to pass through. When the clamping part engages with the clamping groove 12, a downward pulling force can be provided to the support rod. Thus, one end of the support rod body 9 close to the first stage 10 can push against the abutting piece 6, and then one end of the support rod body 9 close to the first stage 10 can firmly abut against the top of the abutting piece 6, and the abutting piece 6 can firmly abut against the top of the decorative plate 3. Therefore, the support rod can be parallel to the first direction, ensuring that the support rod is perpendicular to the base 1. Then install the fastener 13 through the installation part 14 to prevent the fastener 13 from shifting or falling off.

[0046] The charging plug 23 at one end of the power supply data line 22 extends above the lifting part 16. By placing the product 24 in the lifting space, the charging plug 23 can be connected to realize charging of the product, and thus the exhibition of the product 24 is achieved.

[0047] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, but also covers other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.
