[0022] See also Figures 1 to 5In an embodiment of the present invention, a chassis guide rail comprises an intermediate link beam 1, and guide rails 4 are provided at both ends of the intermediate link beam 1. A plug-in slot 9 is opened inside the intermediate link beam 1, and the plug-in slot 9 is opened through the two ends of the guide rail 4. The two guide rails 4 are respectively fixedly connected with a plug-in block 11 at one end close to the plug-in slot 9, and the two plug-in blocks 11 are plugged into the plug-in slot 9. The bottom of the plug-in slot 9 is opened through, and the two guide rails 4 are respectively fixedly connected with a bottom ring 10 at one end away from the intermediate link beam 1, and the fixing direction of the two bottom rings 10 is consistent with the opening direction of the plug-in slot 9.

[0023] Preferably, in this embodiment, the device as a whole is not limited to being made of polymer materials such as ABS, silicone, PC, PE, etc., but can also be made of metal materials or metal + polymer materials. The three parts of the middle link beam 1 and the two guide rails 4 can be integral or separate and are not limited to the connection method, thereby improving the overall use effect of the guide rails. The two guide rails are divided into an upper guide rail and a lower guide rail, which are arranged at both ends of the middle link beam 1. They can be arranged as a split connection structure, or they can be manufactured by integral injection molding or die-casting to make them used as a whole. When installing the chassis, a plug-in connection is performed through the bottom ring 10. When performing a plug-in connection, the tensioning groove of the bottom ring 10 and the limit ring 15 at its bottom are used to reverse the card to ensure the tightness of the connection.

[0024] At the same time, in this embodiment, when the bottom ring 10 is inserted and pulled out, the tensioning groove can ensure a certain contraction effect of the bottom ring 10. When inserted into the positioning hole, the bottom ring 10 can shrink autonomously, and after entering the hole, it can rebound and open to clamp the hole wall, thereby fixing and locking it.

[0025] Both end side walls of the plug-in slot 9 are provided with transverse slots 12 , and the side walls of the two plug-in blocks 11 that match the positions of the transverse slots 12 are fixedly connected with transverse blocks 13 , and the two transverse blocks 13 are plugged and connected with the transverse slots 12 that match the positions.

[0026] A plurality of limit keys 14 are evenly and fixedly connected to the outer walls of the two plug-in blocks 11 and the transverse block 13 .

[0027] Preferably, in this embodiment, the inner walls of the plug-in slot 9 and the transverse slot 12 that match the position of the limit key 14 are fixedly connected with a slot that matches the limit key 14. When the guide rail 4 and the intermediate link beam 1 are plugged in and unplugged through the plug-in block 11 and the plug-in slot 9, the guide rail 4 and the intermediate link beam 1 can be connected and limited by the limit key 14 cooperating with the slot that matches it.

[0028] A connecting plate 2 is fixedly connected to the side wall of the middle link beam 1 away from the insertion groove 9 , and a connecting groove 3 is formed on the end of the connecting plate 2 away from the middle link beam 1 .

[0029] The two guide rails 4 are fixedly connected to the limiting blocks 5 at one end away from the middle link beam 1, and the tops of the two limiting blocks 5 are provided with limiting grooves 6. The side walls of the two guide rails 4 at one end close to the middle link beam 1 are provided with a clamping groove 7, and the ends of the two guide rails 4 close to the clamping groove 7 are penetrated by a through groove 8.

[0030] The outer walls of the two bottom rings 10 at one end away from the guide rail 4 are fixedly connected to the limit ring 15. The two bottom rings 10 and the limit ring 15 are both provided with tensioning grooves, and the middle positions of the two bottom rings 10 are both provided with positioning holes.

[0031] Preferably, in this embodiment, the bottom ring 10 cooperates with the tensioning groove and the positioning hole to quickly position and install the device, thereby improving the installation effect.

[0032] The working principle of the present invention is: when using the present device, it is only necessary to connect the guide rail 4 and the middle link beam 1 according to the internal space of the chassis. When connecting, it is only necessary to plug and connect the plug-in block 11 with the plug-in slot 9, and at the same time, the cross block 13 is plugged and connected with the cross slot 12. When plugging and connecting, the connection of the device is limited by the engagement of the limit key 14 with the slot.

[0033] Then install the device into the chassis. During installation, press the bottom ring 10 directly into the corresponding connecting hole inside the chassis. During the pressing process, the tensioning groove on the bottom ring 10 ensures that the bottom ring 10 can accurately enter the connecting hole inside the chassis. When the bottom ring 10 is pressed, it is positioned through the positioning hole. After the pressing is completed, it is returned to the connecting hole in the chassis through the limit ring 15 to ensure the connection effect and complete the installation of the guide rail.

[0034] After the guide rail is installed, components or circuits can be installed through the clamping slots 7 and through slots 8 on the guide rail 4 .
