[0033] Figure 1 A schematic diagram showing an installation method of an existing drying oven nozzle; Figure 2 Another schematic diagram showing an installation method of an existing drying oven nozzle.

[0034] As Figure 1 shown, during the installation process of an existing drying oven nozzle in the prior art, the existing drying oven nozzle 11 is horizontally placed above the existing drying oven air supply branch pipe 12, and the bottom of the existing drying oven nozzle 11 is fixedly connected to the nozzle mounting bracket 13. In addition, the nozzle mounting bracket 13 is passed through the fixing bolt 14 on the existing drying oven air supply branch pipe 12 to fix the nozzle mounting bracket 13 on the existing drying oven air supply branch pipe 12.

[0035] As Figure 2 shown, due to the shape limitation of the existing drying oven nozzle 11, during the installation process, the nozzle mounting bracket 13 needs to enter the installation space between two existing drying oven nozzles 11 horizontally. Therefore, after the nozzle mounting bracket 13 is fixed on the existing drying oven air supply branch pipe 12, it is necessary to manually adjust the position of the existing drying oven nozzle 11, and it is also necessary to manually adjust the position and direction of the nozzle mounting bracket 13 (such as Figure 2 shown horizontally).

[0036] As Figure 1 shown, at the locking position 15, the nozzle mounting bracket 13 and the fixing bolt 14 are locked and connected through a locking member (such as a locking nut). The existing ventilation plate 16 is welded above the nozzle mounting bracket 13, and the existing ventilation plate 16 is arranged between two existing drying oven nozzles 11.

[0037] Thus, multiple existing drying oven nozzles 11 can be fixed on the air supply branch pipe 12 of the existing drying oven through the nozzle mounting bracket 13, the fixing bolt 14, and the locking member at the locking position 15, so as to complete the installation of the existing drying oven nozzle 11.

[0038] However, the applicant has found that the above-mentioned existing installation method of the drying oven nozzle has problems such as cumbersome installation that requires manual position adjustment, and due to its locking method, it is difficult to disassemble the drying oven nozzle after installation.

[0039] Based on this, according to one aspect of the present application, the present application provides a locking device for a drying oven nozzle.

[0040] Figure 3 A schematic diagram showing a drying oven nozzle according to an embodiment of the present application; Figure 4 A schematic structural diagram showing a locking device according to an embodiment of the present application; Figure 5 A schematic combined diagram showing a locking device and a drying oven nozzle according to an embodiment of the present application.

[0041] As Figure 3 、 Figure 4 and Figure 5 shown, the locking device 2 includes a locking adjustment part 20, a nozzle connecting rod 21, a first locking member (not shown in the figure), a second locking member 22, a fixed connection plate 23, a locking connection plate 24, and a third locking member 25.

[0042] According to an exemplary embodiment, as Figure 3 shown, the locking adjustment part 20 is provided on the surface of the drying oven nozzle 1. For example, the locking adjustment part 20 is a locking adjustment opening formed on the surface of the drying oven nozzle 1.

[0043] According to an exemplary embodiment, as Figure 3 and Figure 5 shown, one end of the nozzle connecting rod 21 is fixed to the locking adjustment part 20 through a first locking member.

[0044] For example, the first locking member is a bolt, and one end of the nozzle connecting rod 21 is fixed to the locking adjustment part 20 through the bolt, and the rotation of the bolt can drive the rotation of the nozzle connecting rod 21.

[0045] According to an exemplary embodiment, as Figure 5 shown, the other end of the nozzle connecting rod 21 is arranged in the groove 31 of the drying oven air supply branch pipe bottom plate 3, and a second locking member 22 is arranged at the other end of the nozzle connecting rod 21.

[0046] Optionally, the second locking member 22 is a hexagonal locking member, such as a hexagonal nut.

[0047] Exemplarily, the second locking member 22 is connected to the other end of the nozzle connecting rod 21 by welding.

[0048] According to the exemplary embodiment, as Figure 4 and Figure 5 shown, the fixed connection plate 23 is arranged on the nozzle connecting rod 21, and both ends of the fixed connection plate 23 are connected to the inner wall of the drying oven nozzle 21.

[0049] For example, both ends of the fixed connection plate 23 are connected to the inner wall of the drying oven nozzle 21 by welding, so that the locking device 2 can be fixedly connected to the drying oven nozzle 1.

[0050] According to the exemplary embodiment, as Figure 5 shown, the locking connection plate 24 is arranged in the groove 31 of the drying oven air supply branch pipe bottom plate 3.

[0051] As Figure 5 shown, the third locking member 25 is arranged on the nozzle connecting rod 21 and passes through the drying oven nozzle 1 to be connected to one side of the locking connection plate 24.

[0052] For example, an opening corresponding to the third locking member 25 is arranged on the bottom plate of the drying oven nozzle 1, and the third locking member 25 passes through the opening and is welded to the locking connection plate 24 in the groove 31 of the drying oven air supply branch pipe bottom plate 3.

[0053] Exemplarily, it can be understood here that since the third locking member 25 is embedded in the bottom plate of the drying oven nozzle 1, the third locking member 25 cannot rotate, but can move up and down.

[0054] Optionally, the third locking member 25 is a hexagonal extended locking member, such as a hexagonal extended nut.

[0055] By setting the third locking member 25 as a hexagonal nut, the rotation of the third locking member 25 can be prevented.

[0056] As Figure 5 shown, the second locking member 22 is arranged on the other side of the locking connection plate 24.

[0057] According to the exemplary embodiment, by adjusting the tightening direction of the first locking member, the nozzle connecting rod 21 rotates to drive the adjustment of the locking force between the locking connection plate 24 and the drying oven air supply branch pipe bottom plate 3, so that the drying oven nozzle 1 is in a locked state or a detachable state.

[0058] For example, rotate the first locking member in the first preset rotation direction (such as the clockwise direction). Under the action of the first locking member, the nozzle connecting rod 21 drives the locking connection plate 24 to move upward. When the locking connection plate 24 moves upward to a certain extent, the locking connection plate 24 is tightly attached to and connected with the bottom plate 3 of the drying oven air supply branch pipe. Since the locking connection plate 24 is fixedly connected to the drying oven nozzle 1 through the nozzle connecting rod 21, the drying oven nozzle 1 can be tightly pressed and connected to the bottom plate 3 of the drying oven air supply branch pipe, so that the drying oven nozzle 1 is in a locked state.

[0059] Also for example, rotate the first locking member in the second preset rotation direction (such as the counterclockwise direction). Under the action of the first locking member, the nozzle connecting rod 21 drives the locking connection plate 24 to move downward. When the locking connection plate 24 moves downward to a certain extent, there is a certain operating space between the locking connection plate 24 and the bottom plate 3 of the drying oven air supply branch pipe, so that the drying oven nozzle 1 is in a detachable state.

[0060] Through the above embodiments, the locking device provided by the present application at least includes a locking adjustment part, a nozzle connecting rod, a first locking member, a second locking member, a fixed connection plate, a locking connection plate, and a third locking member. By adjusting the first locking member at the locking adjustment part, the nozzle connecting rod can be rotated, so that the locking force between the locking connection plate and the bottom plate of the drying oven air supply branch pipe can be adjusted. And by adjusting the magnitude of the locking force, the drying oven nozzle can be in a locked state or a detachable state, which is convenient for the installation and disassembly of the drying oven nozzle.

[0061] The present application uses a locking device to replace the traditional nozzle mounting bracket. Only by adjusting the first locking member can the installation and disassembly of the drying oven nozzle be realized, which has the characteristics of simple installation and convenient disassembly.

[0062] Optionally, as Figure 4 and Figure 5 shown, the locking device 2 further includes at least two fourth locking members 26. At least two fourth locking members 26 are respectively arranged on both sides of the fixed connection plate 23.

[0063] For example, the fourth locking member 26 can be a gasket. By respectively arranging gaskets on both sides of the fixed connection plate 23, the up and down movement of the nozzle connecting rod 21 can be prevented.

[0064] Optionally, as Figure 4 and Figure 5 shown, the locking device 2 further includes a sleeve 27. The top of the nozzle connecting rod 21 is sleeved and arranged in the sleeve 27.

[0065] Since the locking adjustment part 20 is open, by arranging the sleeve 27, the air flow inside the drying oven nozzle 1 can be prevented from flowing out through the locking adjustment part 20.

[0066] Figure 6 A schematic diagram showing the locking groove according to an embodiment of the present application; Figure 7 A schematic diagram showing the detachable groove according to an embodiment of the present application.

[0067] Optionally, as Figure 6 and Figure 7 shown, the groove 31 of the air supply branch pipe bottom plate 3 of the drying oven includes a locking groove 311 and a detachable groove 312.

[0068] The size of the locking groove 311 is smaller than the passable size of the locking connecting plate 24.

[0069] For example, as Figure 6 shown, when the locking connecting plate 24 moves to the locking groove 311 under the action of an external force, when adjusting the tightening direction of the first locking member to drive the locking connecting plate 24 to move upward, due to the size limitation of the locking groove 311, the locking groove 311 will limit the locking connecting plate 24 at the locking groove 311, so that the drying oven nozzle 1 is in a locked state.

[0070] The size of the detachable groove 312 is greater than or equal to the passable size of the locking connecting plate 24.

[0071] For example, as Figure 7 shown, when adjusting the tightening direction of the first locking member to drive the locking connecting plate 24 to move downward, there will be a certain operable space between the locking connecting plate 24 and the air supply branch pipe bottom plate 3 of the drying oven. Based on Figure 7 the arrow direction shown, under the action of an external force, the locking connecting plate 24 can be moved from the locking groove 311 to the detachable groove 312. Since the size of the detachable groove 312 is greater than or equal to the passable size of the locking connecting plate 24, the locking connecting plate 24 can be detached from the air supply branch pipe bottom plate 3 of the drying oven through the detachable groove 312 under the action of an external force, thus completing the disassembly of the drying oven nozzle 1.

[0072] According to another aspect of the present application, the present application provides a drying oven nozzle, and the drying oven nozzle includes the locking device of the drying oven nozzle as described above.

[0073] Optionally, as Figure 3 shown, the drying oven nozzle further includes a ventilation plate 17. The ventilation plate 17 is arranged between two drying oven nozzles 1 and is fixedly connected to the two drying oven nozzles 1.

[0074] For example, the ventilation plate 17 is connected to the two drying oven nozzles 1 respectively by means of bolt fixation.

[0075] With such a setting, compared with the existing method of setting up a mounting bracket at the bottom of the ventilation plate 17 to fix the drying oven nozzle, the drying oven nozzle provided by the present application has the characteristics of simple structure and convenient installation.

[0076] According to another aspect of the present application, the present application also provides a drying oven, including the drying oven nozzle as described above.

[0077] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments, or perform equivalent replacements on some of the technical features.
