[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a locking ring protection device for an industrial furnace, including a lower protective plate 1 and an upper protective plate 2 hinged to the top of the lower protective plate 1. A first locking ring 3 is bonded to the inner side of both the lower protective plate 1 and the upper protective plate 2, and a second locking ring 4 is bonded to the inner side of the first locking ring 3. The side walls of the lower protective plate 1, the upper protective plate 2, the first locking ring 3, and the second locking ring 4 are flush. This three-layer structure effectively protects the furnace opening. A first fixing plate 5 is connected to the bottom of the lower protective plate 1. Two rows of first fixing holes 6 are symmetrically opened on the top of the first fixing plate 5. Installing bolts in multiple first fixing holes 6 for fixing increases the longitudinal stability of the lower protective plate 1. The upper protective plate... A connecting plate 11 is connected to the top rear side of plate 2 by multiple screws. Multiple insert rods 12 are connected side by side to the rear side of the connecting plate 11 by screws. The rear end of the insert rod 12 is fixedly sleeved with a limiting member 15 to prevent the second fixing plate 13 from accidentally detaching from the side wall of the insert rod 12. The second fixing plate 13 is movably sleeved between the side walls of the multiple insert rods 12. The second fixing plate 13 can slide and adjust along the side wall of the insert rod 12 so that the second fixing plate 13 can contact the external structure. Multiple second fixing holes 14 are provided side by side on the upper side wall of the second fixing plate 13. Bolts are screwed into the multiple second fixing holes 14 to connect with the external structure, which can increase the longitudinal stability of the upper protective plate 2.

[0019] Specifically, the left side of both the lower protective plate 1 and the upper protective plate 2 is integrally formed with a fastener 7, and the two fasteners 7 fit together. The middle of each of the two fasteners 7 is constructed with a screw hole, and a locking bolt 8 is screwed between the corresponding screw holes. The lower protective plate 1 and the upper protective plate 2 can be fixed by fixing the two fasteners 7 with the locking bolt 8.

[0020] Furthermore, a nut 9 is screwed to the tail of the locking bolt 8, and the nut 9 abuts against the bottom of the lower fixing part 7 to prevent the locking bolt 8 from loosening.

[0021] Furthermore, a washer 10 is fitted on the side wall of the locking bolt 8, and the washer 10 is supported between the head of the locking bolt 8 and the corresponding side of the upper fixing member 7, so as to prevent the locking bolt 8 from being tightened too much and making it inconvenient to loosen.

[0022] It is worth noting that the fastener 7 and the upper protective plate 2, as well as the fastener 7 and the lower protective plate 1, are both die-cast integral structures. Die-cast integral structures have high strength and are not easily damaged.

[0023] It is worth noting that a handle 17 is connected to the left side of the upper protective plate 2 by screws, and the corners of the handle 17 are rounded. The handle 17 makes it easy to apply force to pull the upper protective plate 2, improving the convenience of use.

[0024] It is worth mentioning that multiple diagonal bracing plates 16 are welded side by side on the rear side of the upper protective plate 2, and the top of the diagonal bracing plates 16 is welded to the corresponding side of the bottom of the connecting plate 11, which increases the stability of the connection between the upper protective plate 2 and the connecting plate 11.

[0025] It is worth emphasizing that the bottom of both the first fixing plate 5 and the lower protective plate 1 are provided with multiple mounting holes arranged side by side, and mounting bolts 18 are screwed between the corresponding mounting holes to increase the stability of the connection between the first fixing plate 4 and the lower protective plate 1.

[0026] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: Move the device to the corresponding side of the industrial furnace. At this time, the first fixing plate 5 is supported on the ground. Flip the upper protective plate 2 and fasten it on the top of the lower protective plate 1. Fix the two fixing parts 7 by locking the bolts 8 to complete the fixation. The three-layer structure of the lower protective plate 1, the upper protective plate 2, the first locking ring 3 and the second locking ring 4 can effectively protect the furnace mouth. Then, the bolts installed in the multiple first fixing holes 6 can increase the longitudinal stability of the lower protective plate 1. Slide the second fixing plate 13 to make it contact the external structure. Then, screw the bolts in the multiple second fixing holes 14 to connect with the external structure, which can increase the longitudinal stability of the upper protective plate 2. Since both the upper protective plate 2 and the lower protective plate 1 are reinforced, they are not easy to loosen after being locked. The above structure combination makes the device more stable after locking.
