The sealing structure of the iron can is characterized in that: the tank body sealing groove comprises a lower tank wall of the tank body sealing groove, an upper tank wall of the tank body sealing groove and a tank bottom of the tank body sealing groove, and a tank bottom mounting interface is arranged between the upper tank wall of the tank body sealing groove and the tank wall of the tank body.

The sealing structure of the iron can is characterized in that: the width of the tank body installation interface and the tank bottom of the tank body sealing groove is matched with the width of the material at the tank bottom.

The sealing structure of the iron can is characterized in that: the tank bottom sealing groove comprises a lower tank bottom sealing groove tank wall, an upper tank bottom sealing groove tank wall and a tank bottom sealing groove tank bottom, and a tank body installation interface is arranged between the lower tank bottom sealing groove tank wall and the bent vertical bars.

The sealing structure of the iron can is characterized in that: the width of the tank body mounting interface and the tank bottom of the sealing groove at the bottom of the tank is matched with the width of the tank body material.

The sealing structure of the iron can is characterized in that: the length of the upper tank wall of the tank body sealing groove is equal to that of the lower tank wall of the tank bottom sealing groove.

The utility model has the beneficial effects that: the tank bottom sealing groove is opposite to the two notches of the tank body sealing groove, the tank walls are alternately sleeved together to carry out compression sealing, 4 layers of tinplate pieces are arranged at the sealing position, and the thickness of the tinplate pieces can bear the weight of the whole iron tank. The sealing structure of the tank body sealing groove and the tank bottom sealing groove can not see the joint of the tank body and the tank bottom from the tank wall, and the tank body is more beautiful and elegant in whole.

Detailed Description

The present invention will be described in further detail with reference to the following examples and the accompanying drawings.

Referring to fig. 1 and 2: a sealing structure of an iron can comprises a can body 2 and a can bottom 1, wherein the bottom of the can body 2 is bent inwards along the can wall to form a C shape to form a can body sealing groove 21. The tank sealing groove 21 comprises a tank sealing groove lower groove wall 2101, a tank sealing groove upper groove wall 2102 and a tank sealing groove bottom 2103, and a tank bottom mounting interface 22 is arranged between the tank sealing groove upper groove wall 2102 and the tank wall of the tank 2.

The periphery of the can bottom 1 is bent upwards to form a bent vertical strip 12, and then is bent downwards to form a C shape to form a can bottom sealing groove 11. The tank bottom sealing groove 11 comprises a tank bottom sealing groove lower groove wall 1101, a tank bottom sealing groove upper groove wall 1102 and a tank bottom sealing groove bottom 1103. A tank body installation interface 13 is arranged between the lower tank wall 1101 of the tank bottom sealing groove and the bent vertical bar 12.

The bottom 1103 of the tank bottom sealing groove 11 penetrates through the tank bottom mounting interface 22, and the upper tank wall 1102 of the tank bottom sealing groove is sleeved in the tank bottom sealing groove 11; the tank sealing groove bottom 2103 penetrates the tank installation interface 13, so that the tank sealing groove upper groove wall 2102 is sleeved in the tank bottom sealing groove 11. The tank bottom sealing groove 11 and the tank body sealing groove 21 are formed to be opposite, the groove walls are sleeved in a crossed mode, and then the pressing sealing treatment is carried out.

The sealing part is provided with 4 layers of tinplate iron sheets, and the thickness of the tinplate iron sheets can bear the weight of the whole iron can. The groove walls of the two notches are pressed and are pressed in a crossed manner, so that air between the groove walls is squeezed. And the tank bottom mounting interface 22 is lower than the tank body mounting interface 13 to isolate air from entering the tank body interior.

Preferentially, the width of the tank body installation interface 22 and the tank body sealing groove bottom 2103 is matched with the width of the material of the tank bottom 1. The width of the tank body installation interface 13 and the tank bottom sealing groove 1103 is matched with the width of the material of the tank body 2. By the design, the bottom 1103 of the tank bottom sealing groove is closely matched with the tank wall of the tank body 2 and the tail end of the upper tank wall 2102 of the tank body sealing groove; the tank bottom 2103 is closely matched with the bent vertical bar 12 and the tail end of the tank bottom sealing groove lower tank wall 1101.

Preferably, the tank bottom sealing groove upper groove wall 2102 and the tank bottom sealing groove lower groove wall 1101 have the same length. The design enables the tank bottom sealing groove 11 and the tank body sealing groove 21 to be filled up, and air is prevented from entering.

The utility model has the beneficial effects that: the two notches of the tank bottom sealing groove and the tank body sealing groove are oppositely and alternately sleeved together to carry out the compression sealing treatment, the sealing position has 4 layers of tinplate iron sheets, and the thickness can bear the weight of the whole iron tank. The connection mode of the sealing structure of the tank body sealing groove and the tank bottom sealing groove can not be seen from the appearance, and the whole tank body is more beautiful and elegant.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
