[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0028] like Figure 1-6 As shown, a pipe joint of a stove includes

[0029] The joint body is fixedly arranged between the stove body 1 and the pipe 2, and the joint body includes a plurality of connecting blocks 3, a plurality of card blocks 4, a support block 5 and a fitting block 6. The support block 5 and the fitting block 6 are fixedly connected, and the distance between the support block 5 and the stove body 1 is greater than the distance between the fitting block 6 and the stove body 1. Several of the connecting blocks 3 are arranged in a circular array on the fitting block 6 on the side away from the support block 5, and several of the card blocks 4 are arranged in a circular array on the support block 5 on the side away from the fitting block 6, and the support block 5 is adapted to the pipe 2; the cross section of the connecting block 3 is "Z"-shaped, and the internal angle of the "Z" is greater than or equal to 90 degrees; the card blocks 4 are tough, and the card blocks 4 are all in contact with the pipe 2; the thickness of the card block 4 on the side close to the support block 5 is less than the thickness on the other side;

[0030] A plurality of fastening grooves 7, each of which is provided on the surface of the stove body 1 and is adapted to the connecting block 3;

[0031] A fixing groove 8 is provided on the surface of the stove body 1 , and a fixing column 9 is fixedly connected to the surface of the connecting block 3 , and the fixing column 9 is adapted to the fixing groove 8 ;

[0032] In actual application, the pipe joint of the stove is configured to have a structure including a "Z"-shaped connecting block 3 and a clamping block 4, wherein the clamping block 4 has different thicknesses and is tough and can be rotated along the thinner part, so that the clamping block 4 can directly contact the pipe 2 by being turned, and the turning points of different thicknesses contact the folds of the pipe 2, thereby fixing the position between the pipe 2 and the joint body. A clamping groove 7 is provided on the surface of the stove, and one side of the connecting block 3 is pressed against the side of the stove body 1 away from the pipe 2 through the clamping groove 7, and the fixing column 9 on the surface of the joint body is rotated and contacts the fixing groove 8, thereby fixing the joint body and the stove body 1. Then, the position between the joint body, the pipe 2 and the stove body 1 can be fixed by simply turning and rotating. The operation is simple and the installation can be completed quickly.

[0033] In some specific embodiments, a plurality of connecting grooves 10 are formed on the surface of the stove body 1. The distance between the connecting grooves 10 is less than the diameter of the pipe 2. The connecting grooves 10 and the agglomerating blocks 4 are staggered. Thus, gas or liquid such as water vapor generated inside the stove body 1 can flow along the connecting grooves and the pipe 2. The staggered connecting grooves 10 and the agglomerating blocks 4 prevent gas flowing upward from the connecting grooves 10 from directly contacting the agglomerating blocks 4, thereby reducing contact between the agglomerating blocks 4 and liquid or gas, and avoiding rust on the surface of the agglomerating blocks 4, which may be detrimental to use.

[0034] In some specific embodiments, the fitting block 6 includes a horizontal block and several sunken blocks, the horizontal block is annular, and the outer radius of the horizontal block is smaller than the distance from the clamping groove 7 to the center of the horizontal block, and the inner radius of the horizontal block is larger than the distance from the connecting groove 10 to the center of the horizontal block; the surface of the horizontal block fits with the stove body 1, the length of the sunken block is equal to the depth of the clamping groove 7, and several sunken blocks are spaced apart on the side of the horizontal block close to the clamping groove 7; through the different shapes of the fitting block 6, it can be fixed at different heights of the connecting block 3, so that two surfaces of the sunken block are in contact with the stove body 1, so that the fit between the joint body and the stove body 1 is tighter;

[0035] In a further embodiment, the width of the connection position of the locking block 4 with the horizontal block is greater than the width of the connection position of the connecting block 3 with the sunken block, and the connection position of the connecting block 3 with the sunken block is adapted to the locking groove 7; thus, the position where the connecting block 3 slides into the inside of the locking groove 7 is limited, and after the connecting block 3 and the locking groove 7 are fitted together, part of the surface of the connecting block 3 contacts the surface of the stove body 1, preventing the connecting block 3 from sliding completely into the stove body 1, thereby quickly realizing the positioning of the fixing column 9 and the fixing groove 8, and ensuring that the joint body does not slide up and down during use;

[0036] In a further embodiment, the cross section of the support block 5 is in an inverted U-shape, and the maximum distance between the support block 5 and the stove body 1 is greater than the distance between the support block 5 and the side of the clamping block 4 away from the support block 5; because the height of the support block 5 is greater than the height of the clamping block 4, after the clamping block 4 is fixed to the pipe 2, there is still a partial contact area on the surface of the support block 5 with the pipe 2, further limiting the position of the pipe 2 inside the joint body and stabilizing the connection;

[0037] The working principle of the present invention is as follows: first, the pipe 2 is inserted into the inner area of ​​the support block 5 and contacts with the locking block 4, and then the locking block 4 is pulled toward the surface of the pipe 2 to make the surface of the locking block 4 fit with the pipe 2, and the position between the pipe 2 and the joint body is fixed, and then the locking block 4 is slid into the inside of the locking groove 7 corresponding to the position of the locking block 4 and the locking groove 7, and the fixing column 9 is inserted into the inside of the fixing groove 8, and the position of the joint body and the stove body 1 is fixed.

[0038] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
