Description

Technical Field

[0001] This invention belongs to the field of mechanical structure design, and in particular relates to a non-through installation mechanism for a load-bearing guide rail at the bottom of a non-metallic airtight packaging box. Background Technology

[0002] Medium and large airtight packaging boxes generally use internal trailers to secure the contents inside the box and facilitate loading and unloading. Bottom guide rails are usually installed inside the box to guide the trailer and reinforce the box.

[0003] For non-metallic airtight packaging boxes, the bottom guide rails often need to be installed by bolts and nuts through the box body. Although this installation method can ensure the airtightness of the entire box to a certain extent through sealing means such as sealing rings, the large number of bolts and nuts distributed will still have a significant impact on the airtightness of the packaging box during long-term use, and it is very easy to cause gas leakage in the box body after repeated use. Summary of the Invention

[0004] The purpose of this utility model is:

[0005] This utility model proposes a bottom guide rail installation mechanism for a non-metallic airtight packaging box, which achieves the installation and fixation of the bottom guide rail without penetrating the non-metallic airtight packaging box body.

[0006] The technical solution of this utility model:

[0007] An installation mechanism for the bottom guide rail of a non-metallic airtight packaging box consists of a bottom guide rail 1, a packaging box bottom plate 2, a U-shaped lock 3, a bottom connecting bridge 4, and a carbon fiber reinforced beam 5.

[0008] The bottom plate 2 of the packaging box has multiple grooves, and a hollow bottom connecting bridge 4 is installed through each groove to position the U-shaped buckle 3 when it is connected to the bottom guide rail 1. The U-shaped buckle 3 is connected and fixed to the bottom guide rail 1 by four sets of bolts and nuts. A certain gap is created between the U-shaped buckle 3 and the bottom plate 2 of the packaging box through the positioning of the bottom connecting bridge 4 to facilitate the application of the connection pre-tightening force. To improve the connection strength and rigidity of the installation mechanism, a carbon fiber reinforcing beam 5 is embedded inside the bottom connecting bridge 4 to play a role in shaping and reinforcement.

[0009] Its characteristic feature is that the bottom guide rail 1 is integrally formed from metal material and is used to guide the trailer inside the box and reinforce the box body.

[0010] Its characteristic is that the bottom plate 2 of the packaging box is made of lightweight and corrosion-resistant non-metallic material.

[0011] Its characteristic feature is that the U-shaped latch 3 is machined from aluminum alloy material.

[0012] Its distinguishing feature is that the bottom connecting bridge 4 is integrally formed with the packaging box.

[0013] Its characteristic feature is that the bottom guide rail 1 is laid in the center at the center line of the bottom connecting bridge 4.

[0014] The beneficial effects of this utility model are:

[0015] 1) The bottom guide rail is installed using a non-through-body method to avoid airtightness problems.

[0016] 2) Reduce the difficulty of installing bottom-mounted missiles and improve work efficiency;

[0017] 3) Improve the rigidity of the bottom of the packaging box to avoid rigidity issues caused by the assembly of metal guide rails and non-metallic boxes. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figure 1-2 As shown, the installation mechanism of the bottom guide rail of the non-metallic airtight packaging box of this utility model consists of a bottom guide rail 1, a packaging box bottom plate 2, a U-shaped lock 3, a bottom connecting bridge 4, and a carbon fiber reinforcing beam 5.

[0022] The bottom plate 2 of the packaging box has multiple grooves, and a hollow bottom connecting bridge 4 is installed through each groove to position the U-shaped buckle 3 when it is connected to the bottom guide rail 1. The U-shaped buckle 3 is connected and fixed to the bottom guide rail 1 by four sets of bolts and nuts. A certain gap is created between the U-shaped buckle 3 and the bottom plate 2 of the packaging box through the positioning of the bottom connecting bridge 4 to facilitate the application of the connection pre-tightening force. To improve the connection strength and rigidity of the installation mechanism, a carbon fiber reinforcing beam 5 is embedded inside the bottom connecting bridge 4 to play a role in shaping and reinforcement.

[0023] The bottom guide rail 1 is made of metal and is used to guide the trailer inside the box and reinforce the box body; the bottom plate 2 of the packaging box is made of non-metallic material, which has the characteristics of being lightweight and corrosion resistant. To improve the bottom rigidity, multiple grooves are set on the bottom plate 2; the U-shaped buckle 3 is machined from aluminum alloy and is used to connect and fasten the bottom guide rail 1; the bottom connecting bridge 4 is integrally formed with the packaging box and has a hollow design for installing the carbon fiber reinforcing beam 5; the carbon fiber reinforcing beam 5 is made of carbon fiber material, which has the characteristics of being lightweight and high-strength, and is used to reinforce the bottom connecting bridge 4.

[0024] After the packaging box is formed, the carbon fiber reinforced beam 5 is first installed into the hollow part of the bottom connecting bridge 4. It should be noted that the two should be interference fit. Next, the bottom guide rail 1 is laid in the center at the center line of the bottom connecting bridge 4. Finally, the U-shaped lock 3 is used with bolts and nuts to connect and fasten the bottom guide rail 1 and the bottom connecting bridge 4, ensuring that the bottom guide rail 1 and the bottom plate 2 of the packaging box are completely in contact.

[0025] Since metal guide rails cannot be welded to non-metallic boxes, this installation method completely avoids the connection method that penetrates the box during the connection process between the guide rail and the box, thus improving the overall airtightness of the packaging box. At the same time, the installation process and subsequent adjustments are convenient and quick. The carbon fiber reinforcement beams used can further strengthen the box and ensure that the overall strength and rigidity meet the usage requirements.
