Description

Technical Field

[0001] The utility model relates to the technical field of stove burner manufacturing, in particular to a fixing structure of a stove burner fire cover. Background Art

[0002] In the prior art, the fire cover of the stove burner is usually made of copper or copper alloy and the surface is spray-painted black.

[0003] However, with the progress of the times, people's requirements for a clean and bright kitchen are gradually increasing, which requires the surface of the stove burner to be bright and smooth. Therefore, the fire cover needs to be made of stainless steel and surface polished to achieve this.

[0004] However, since the stainless steel material is completely different from copper or copper alloy material during processing, if the fire cover made of stainless steel is still to be made into the same structure as the original fire cover, not only will the cost increase, but its strength will also fail to meet the requirements.

[0005] Therefore, how to make the stainless steel burner cover match the copper or copper alloy burner fire cover and reduce the manufacturing cost as much as possible while meeting market expectations has become a technical problem that technical personnel in this field urgently need to solve.

[0011] The upper cover body fixing plate comprises a ring-shaped fixing plate body, and a plurality of inner hook feet and a plurality of outer hook foot groups arranged around the outer side of the fixing plate body;

[0012] The fixing plate body is fixed to the bottom of the circular flange structure;

[0013] A plurality of the outer hook groups form a conical tube structure coaxially arranged with the circular tube;

[0014] The farther the tapered tube structure is from the circular flange structure, the larger the diameter of the part thereof;

[0015] Each of the outer hook foot groups includes at least one outer hook foot;

[0016] The fixing spring is arranged inside the maximum diameter position of the conical tube structure;

[0017] The fixing spring is an open elastic metal circle;

[0018] Each of the inner hook feet is arranged between two adjacent outer hook foot groups, and has a hook at the lower end extending toward the axis direction of the circular tube, and the fixing spring is constrained in the conical tube structure by the hook;

[0019] The inner wall of the fire cover body is provided with a slot corresponding to each of the outer hook feet;

[0020] Each of the side walls of the slot is provided with a barb at a position located above the opening of the fire cover body;

[0021] The side of each barb facing the upper opening of the fire cover body is an inclined surface, and the side facing away from the upper opening of the fire cover body is a restraining surface. The fixing spring is hooked by the corresponding restraining surface to restrain the fixing spring in the fire cover body.

[0022] Preferably, the fixing plate body is fixed to the bottom surface of the circular flange structure by welding.

[0032] Example

[0033] like Figures 1 to 4 As shown, the fixing structure of the fire cover of the stove burner includes a fire cover upper cover assembly 1 made of stainless steel material, and a fire cover body 2 made of copper or copper alloy;

[0034] The fire cover upper cover assembly 1 includes a fire cover upper cover body 11, an upper cover body fixing plate 12 and a fixing spring 13;

[0035] The fire cover upper cover body 11 is a circular tube with a circular flange structure at one end;

[0036] An upper cover body fixing plate 12 is provided below the circular flange structure of the fire cover upper cover body 11;

[0037] The upper cover body fixing plate 12 includes a ring-shaped fixing plate body, and a plurality of inner hook feet 12a and a plurality of outer hook foot groups arranged around the outer side of the fixing plate body;

[0038] The fixing plate body is fixed to the bottom of the circular flange structure;

[0039] A plurality of outer hooks are grouped to form a tapered tube structure coaxially arranged with the circular tube;

[0040] The farther the tapered tube structure is from the circular flange structure, the larger the diameter is;

[0041] Each outer hook foot group includes at least one outer hook foot 12b;

[0042] A fixing spring 13 is provided on the inner side of the maximum diameter position of the conical tube structure;

[0043] The fixing spring 13 is an open elastic metal circle;

[0044] Each inner hook foot 12a is arranged between two adjacent outer hook foot groups, and has a hook extending toward the axis of the circular tube at the lower end, and the fixing spring 13 is constrained in the conical tube structure through the hook;

[0045] The inner wall of the fire cover body 2 is provided with a slot 21 corresponding to each outer hook foot 12b;

[0046] Each side wall of the slot 21 is provided with a barb 22 at the position of the opening above the fire cover body 2;

[0047] The side of each barb 22 facing the upper opening of the fire cover body 2 is an inclined surface, and the side facing away from the upper opening of the fire cover body 2 is a restraining surface. The fixing spring 13 is hooked by the corresponding restraining surface to restrain the fixing spring 13 in the fire cover body 2.

[0048] When installing the utility model, the fixing spring 13 first hits the barb 22 on the side wall of each slot 21 in the fire cover body 2, which is located at the upper opening of the fire cover body 2;

[0049] Under the action of the conical tube structure surrounded by multiple outer hook foot groups, the fixing spring 13 is compressed along the inclined surface of the barb 22, and each outer hook foot 12b slides along the corresponding slot 21, so that the fire cover upper cover body 11 slides into the fire cover body 2, thereby fixing the fire cover upper cover group 1 and the fire cover body 2 as a whole.

[0050] In some embodiments, the fixing plate body is fixed to the bottom surface of the circular flange structure by welding.

[0051] In practical applications, the fixing plate body and the bottom surface of the circular flange structure are usually welded together by spot welding.

[0052] In some embodiments, two contact surfaces where the fixing plate body and the circular flange structure meet are respectively provided with a plurality of pairs of mutually matching positioning protrusions 12c and corresponding grooves, and positioning is performed by the plurality of pairs of mutually matching positioning protrusions 12c and corresponding grooves.

[0053] In some embodiments, it is preferred that one of the multiple external hook foot groups includes an external hook foot group having a number of external hook feet 12b that is different from the number of external hook feet 12b included in all other external hook foot groups, and the number of corresponding slots 21 is also different from the number of corresponding slots 21 in all other external hook foot groups.

[0054] In actual applications, it is best if one of the multiple outer hook foot groups has an outer hook foot group with a number of outer hook feet 12b that is different from the number of outer hook feet 12b included in all other outer hook foot groups to prevent misinstallation. Since the outer hook feet 12b of the fire cover upper cover group 1 and the internal card slots 21 of the fire cover main body 2 are in a one-to-one correspondence, the fire cover upper cover group 1 cannot be inserted into the fire cover main body 2 when they are not aligned.

[0055] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
