[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A high-speed train duct grille includes a fixed frame 1, with a grille outer frame 2 installed on the inner side of the fixed frame 1. Multiple placement slots are arranged at both ends of the inner wall of the grille outer frame 2. Placement blocks 13 are slidably connected to the inner side of the placement slots. Grille panels 3 are rotatably connected between two sets of placement blocks 13. The two sets of placement blocks 13 are engaged with the grille outer frame 2 via a locking mechanism. The locking mechanism includes an insert plate 4, a docking component, and a spinning component. The insert plate 4 is installed on one side of the outer wall of one set of placement blocks 13. The docking component is used to initially position the grille panel 3, and the spinning component, in conjunction with the docking component, locks or unlocks the position of the grille panel 3. In use, the device allows for initial positioning of the grille panel 3 via the docking component, and locking or unlocking of the position via the spinning component. The structure is simple and easy to operate, facilitating quick disassembly and assembly of individual grille panels 3 for timely maintenance and repair. New grille panels 3 can be quickly installed to ensure subsequent use without the need to separate all grille panels 3, further improving practicality.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the docking assembly includes multiple sets of movable rods 5 slidably connected inside the outer frame 2 of the grille. A reset groove is provided inside the outer frame 2 on the outside of the movable rods 5. A reset plate 6 is slidably connected inside the reset groove. The reset plate 6 is rotatably connected to the movable rods 5. A first spring 14 is installed between the two ends of one side of the reset plate 6 and the inner wall of the reset groove. A slot is provided on the top of the outer frame 2 on one side of the placement groove. The insert plate 4 is slidably connected to the slot. First, after the placement block 13 and the grille plate 3 are placed in place, the insert plate 4 will also be inserted into the inner side of the slot. Then, the pull ring 12 can be fastened and the movable rod 5 can be twisted to make the locking block 8 rotate to the longitudinal direction.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the insert plate 4 has a mating groove 7 extending to one end of the grid frame 2. The grid frame 2 has a retraction groove on the other side of the mating groove 7 near the insert plate 4. The movable rod 5 has a locking block 8 installed at one end extending into the retraction groove. Then, the pull ring 12 is pressed to drive the locking block 8 through the mating groove 7 into the installation groove. At this time, the positioning block 11 engages with the positioning groove. The pull ring 12 is held in place and the movable rod 5 is continuously pressed downward, which drives the reset plate 6 to compress the second spring 15. After the locking block 8 is fully inserted into the installation groove, it is pulled back a certain distance.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the side cross section of the docking groove 7 is cross-shaped. The docking groove 7 and the locking block 8 are slidably connected. The movable rod 5 is slidably connected to the center of the docking groove 7. The diameter of the movable rod 5 is greater than the width of the cross-shaped port of the docking groove 7. The spinning assembly includes an installation groove located inside the outer frame 2 of the grille on the other side of the docking groove 7. The side cross section of the installation groove is circular. The base plate 9 is rotatably connected to the inner side of the installation groove. The top two ends of the base plate 9 are equipped with second springs 15. Furthermore, the two sets of second springs 15 return to their original position and spring back. The protruding ends on both sides of the locking block 8 are also inserted into the inner side of the slot. The springback of the second springs 15 allows the docking plate 10 to press the locking block 8 against the inner side of the slot. At this time, the insert plate 4 cannot be pulled out inside the slot, thereby achieving the locking effect.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a docking plate 10 is installed at the top of the second spring 15, and a positioning block 11 is installed at the top of the docking plate 10. A positioning groove is opened at the bottom of the locking block 8 to engage with the positioning block 11. The docking plate 10 is slidably connected to the inner side of the mounting groove. The two ends of the inner wall of the mounting groove are provided with locking grooves near the docking groove 7. The locking block 8 is engaged with the locking groove. The movable rod 5 extends to the outer side of the outer frame 2 of the grille and is rotatably connected to a pull ring 12. Furthermore, when it is necessary to maintain the grille panel 3, the movable rod 5 can be pressed again to move the locking block 8, the docking plate 10 and the second spring 15 down a certain distance, so that the locking block 8 is away from the inner side of the locking groove. Then, the base plate 9 is rotated to move it after it is offset from the locking groove. The locking block 8 can be pulled out from the cross port in the other direction of the docking groove 7. The locking block 8 enters the inner side of the retraction groove. At this time, the damaged and deformed grille panel 3 can be removed for inspection and maintenance or replacement with a new grille panel 3.

[0029] The implementation principle of the air duct grille of a high-speed train according to an embodiment of this application is as follows: After the placement block 13 and the grille plate 3 are placed in place, the insert plate 4 will also be inserted into the inner side of the slot. Then, the pull ring 12 can be fastened and the movable rod 5 can be twisted to make the locking block 8 rotate longitudinally. Then, the pull ring 12 is pressed to drive the locking block 8 through the inner side of the docking groove 7 into the inner side of the installation groove. At this time, the positioning block 11 is engaged with the positioning groove. The pull ring 12 is fastened and the movable rod 5 is pressed downward to drive the reset plate 6 to compress the second spring 15. After the locking block 8 is fully inserted into the inner side of the installation groove, it is pulled back a certain distance. The two sets of second springs 15 then reset and rebound. The protruding ends on both sides of the locking block 8 also return to their original positions. The second spring 15 rebounds and the mating plate 10 presses the locking block 8 against the inside of the slot. At this time, the insert plate 4 cannot be moved inside the slot, thus achieving a locking effect. When it is necessary to maintain the grid panel 3, the movable rod 5 can be pressed again to move the locking block 8, the mating plate 10 and the second spring 15 down a certain distance, so that the locking block 8 is away from the inside of the slot. Then, the base plate 9 is rotated to move it out of the slot. After moving it, the locking block 8 can be pulled out from the cross port of the mating slot 7 in the other direction. The locking block 8 enters the retraction groove. At this time, the damaged and deformed grid panel 3 can be removed for inspection and maintenance or replacement with a new grid panel 3.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
