[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 The present invention provides a technical solution: a quick-install furnace cover for an electric furnace, comprising a cover body 1, an exhaust cover 2, a follower locking device 3, and a quick-locking device 4. The cover body 1 is snapped onto the furnace body. A protrusion, or flange structure, is provided at the connection between the furnace body top and the cover body 1, facilitating tightening of the quick-locking device 4.

[0023] An exhaust port is provided on the top of the cover body 1, and an exhaust cover seat 11 is provided at the exhaust port of the cover body 1. The top surface of the exhaust cover seat 11 is covered with the exhaust cover 2, and the exhaust cover 2 is provided with a plurality of exhaust holes. The exhaust cover 2 is provided with the follow-up locking device 3, and the bottom surface of the follow-up locking device 3 is connected to the top surface of the cover body 1. The follow-up locking device 3 is used to lock the exhaust cover 2 with the exhaust cover seat 11. The top surface of the cover body 1 is rotatably connected to the center of the quick-fastening device 4, and one end of the quick-fastening device 4 is slidably connected to the top of the exhaust cover 2, and the other end of the quick-fastening device 4 is used to connect the cover body 1 and the electric furnace body.

[0024] The exhaust cover 2 is used to discharge the exhaust gas generated in the heating process of the electric furnace body. The exhaust hole of the exhaust cover 2 is provided with a filter device, which is used to filter the exhaust gas to reduce the harmfulness of the discharged gas as much as possible.

[0025] Furthermore, the exhaust cover 2 includes a filter cover 21 and a top plate 22. The top surface of the filter cover 21 is connected to the top plate 22. Both the filter cover 21 and the top plate 22 are provided with exhaust holes. The exhaust holes of the filter cover 21 are connected to the exhaust holes of the top plate 22. The bottom surface of the top plate 22 is connected to the top surface of the follow-up locking device 3.

[0026] Furthermore, the follow-up locking device 3 includes a follow-up housing 31, a fixed column 32, a limiting rod 33, a locking head 34 and a telescopic rod 35. The top surface of the follow-up housing 31 is connected to the bottom surface of the top plate 22. The follow-up housing 31 is slidably connected to the outer surface of the fixed column 32. The bottom surface of the fixed column 32 is fixedly connected to the top surface of the cover body 1. The outer surface of the fixed column 32 is provided with the limiting rod 33 near the cover body 1. The limiting rod 33 is slidably sleeved with the locking head 34. The top of the locking head 34 is rotatably connected to one end of the telescopic rod 35, and the other end of the telescopic rod 35 is rotatably connected to the outer side wall of the follow-up housing 31.

[0027] A positioning groove 12 is formed on the side wall of the exhaust cover seat 11 , and a positioning opening 211 is formed on the side wall of the filter cover 21 . The positioning groove 12 is communicated with the positioning opening 211 , and the locking head 34 passes through the positioning opening 211 and enters the positioning groove 12 .

[0028] It should be noted that the depth of the positioning opening 211, that is, the wall thickness of the filter cover 21 at the positioning opening 211, should be less than one-third of the length of the locking head 34. This prevents the locking head 34 from getting stuck due to the excessive thickness of the positioning opening 211 when the follower housing 31 is raised.

[0029] Furthermore, the quick-fastening device 4 includes a pushing rod 41, a bent arm fastening rod 42 and a slider 43. The top surface of the top plate 22 is provided with a sliding groove 212. One end of the pushing rod 41 is rotatably connected to the slider 43. The other end of the pushing rod 41 is hinged to one end of the bent arm fastening rod 42. The other end of the bent arm fastening rod 42 is fastened to the electric furnace body. The top surface of the cover body 1 is provided with a bent arm column 13. The end of the bent arm fastening rod 42 connected to the pushing rod 41 is rotatably connected to the top of the bent arm column 12.

[0030] The pushing rod 41 is hinged to the bent arm locking rod 42. When the bent arm locking rod 42 is lifted, the pushing rod 41 is lifted upward and drives the slider 43 to slide toward the two end surfaces of the top plate 22. In other words, when the bent arm locking rod 42 is locked, the pushing rod 41 is pressed downward to cause the slider 43 to slide toward the center of the top plate 22.

[0031] Furthermore, a handle 44 is provided on the outer side of the bent arm buckle rod 42. It is convenient for the operator to lift the buckle rod 42. Figure 1 The present invention does not limit the installation position of the handle 44 , and the installation position of the handle 44 can also be changed to the inner side of the bent arm buckle rod 42 .

[0032] Furthermore, a sealing ring 23 is provided on the bottom surface of the filter cover 21 .

[0033] Working principle:

[0034] When not installed, the bent arm fastening rod 42 is in a raised state. First, buckle the cover body 1 onto the electric furnace body. At this time, the operator pulls the handle 44 to pull the bent arm fastening rod 42 inward. The push rod 41 is subjected to the force of the hinge to press downward. The other end of the bent arm fastening rod 42 is clamped on the flange bottom surface of the electric furnace body to fasten the cover body 1 to the electric furnace body. At this time, the push rod 41 generates a thrust on the top plate 22, thereby buckling the filter cover 21 onto the exhaust cover seat 11. The top plate 22 presses down the follower shell 31, thereby driving the telescopic rod 35 to push the locking head 34 through the positioning port 211 into the positioning groove to complete the locking.

[0035] When the cover 1 needs to be lifted, the operator pulls up the curved arm locking rod 42. At this point, the hinged force causes the curved arm locking rod 42 to lift upward, and the hinged force causes the push rod 41 to also lift upward. At this point, the push force exerted by the push rod 41 on the top plate 22 disappears, causing the sliders 43 to slide toward the ends of the top plate 22. The return force of the spring at the top of the fixed column 32 pushes the follower housing 31 upward, thereby raising the top plate 22 and the filter cover 21. At this point, the rise of the follower housing 31 pulls the telescopic rod 35, which in turn pulls the locking head 34 out of the positioning opening 211.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
