Description

Technical Field

[0001] The utility model relates to the technical field of stove burner manufacturing, in particular to a stove burner fire cover fixing structure which can prevent the fire cover from being mis-installed. Background Art

[0002] The burner fire cover upper cover and the burner fire cover body are separate. Customers may install them incorrectly during use, resulting in problems such as backfire.

[0003] When the burner fire cover upper cover and the burner fire cover body are fixed as one, installation, disassembly and cleaning are convenient. Therefore, this good fixing method can be used in many burners. However, when products with similar structures use the same fixing method, the burner fire cover upper cover and the burner fire cover body may be misassembled, resulting in high smoke, fire leakage or other safety hazards.

[0004] Therefore, how to prevent the upper cover of the stove burner fire cover and the burner fire cover body from being misassembled becomes a technical problem that those skilled in the art need to solve urgently. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the utility model provides a stove burner fire cover fixing structure for preventing the fire cover from being misassembled, so as to prevent the stove burner fire cover upper cover and the burner fire cover main body from being misassembled.

[0006] To achieve the above purpose, the utility model discloses a stove burner fire cover fixing structure for preventing the fire cover from being misinstalled, comprising a fire cover body in a circular tubular shape with an opening on the top, and a fire cover upper cover arranged on the opening above the fire cover body.

[0007] Wherein, the fire cover upper cover and the fire cover main body are detachably connected by a plurality of groups of clamping parts evenly distributed around the axis;

[0008] Each set of the clamping parts includes at least one pair of mutually matching clamping hooks and corresponding clamping slots;

[0009] Each of the hooks is arranged at a position close to the edge of the lower cover of the fire cover, and the corresponding slots are arranged at a position close to the upper opening on the inner wall of the fire cover body;

[0010] Among the plurality of groups of the clamping components, at least one group of the clamping components comprises a number of clamping hooks and corresponding clamping slots that is different from that of the remaining groups of the clamping components.

[0011] Preferably, the fire cover upper cover and the fire cover main body are detachably connected by three groups of the clamping parts evenly distributed around the axis;

[0012] Among the three groups of the clamping parts, two groups of the clamping parts each include only one clamping hook and one corresponding clamping slot, and one group of the clamping parts includes two clamping hooks and two corresponding clamping slots.

[0013] Preferably, an annular spring is provided on the inner side of the annular shape surrounded by the plurality of hooks, and is compressed in the corresponding slot by the elasticity of the spring, and a detachable connection is achieved between the spring and the corresponding slot.

[0014] Beneficial effects of the utility model:

[0015] The application of the utility model can effectively prevent the fire covers of stove burners of different models from being mis-installed, and can also prevent the fire covers of stove burners of the same model from being mis-installed.

[0016] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] like Figures 3 to 6As shown, the stove burner fire cover fixing structure for preventing the fire cover from being misinstalled includes a fire cover main body 2 which is in a circular tubular shape and has an opening on the top, and a fire cover upper cover 1 which is arranged on the top of the fire cover main body 2 and has an opening.

[0027] The fire cover upper cover 1 and the fire cover main body 2 are detachably connected by a plurality of groups of clamping parts evenly distributed around the axis;

[0028] Each set of the clamping parts includes at least one pair of mutually matching clamping hooks 11 and corresponding clamping slots 21;

[0029] Each of the hooks 11 is disposed at a position close to the edge of the lower surface of the fire cover upper cover 1, and the corresponding slots 21 are disposed at a position close to the upper opening on the inner wall of the fire cover main body 2;

[0030] Among the plurality of groups of the clamping components, at least one group of the clamping components includes a number of the clamping hooks 11 and the corresponding clamping slots 21 that is different from that of the remaining groups of the clamping components.

[0031] In some embodiments, the fire cover upper cover 1 and the fire cover main body 2 are detachably connected by three groups of the clamping parts evenly distributed around the axis;

[0032] Among the three groups of the clamping parts, two groups of the clamping parts only include one clamping hook 11 and one corresponding clamping slot 21 , and one group of the clamping parts includes two clamping hooks 11 and two corresponding clamping slots 21 .

[0033] In some embodiments, an annular spring 3 is provided on the inner side of the ring surrounded by the plurality of hooks 11 , and is compressed in the corresponding slot 21 by the elasticity of the spring 3 , and is detachably connected to the corresponding slot 21 .

[0034] like Figure 7 As shown, when different types of fire cover upper covers 1 are installed on the fire cover main body 2, the hook 11 of the fire cover upper cover 1 does not match the slot 21 of the fire cover main body 2 and collides with each other, resulting in failure to install.

[0035] like Figure 8 As shown, the fire cover upper cover 1 of the same model is installed on the fire cover main body 2. When the clips are not completely aligned, it cannot be installed because the number of the hooks 11 and the corresponding slots 21 included in at least one group of the multiple groups of the clips is different from that of the other groups of the clips. Even after being misaligned, it cannot be installed to the bottom, and the outer side of the hook 11 will collide with the inner side of the fire cover main body 2 and cannot be installed.

[0036] 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.
