[0002] The oven is a common appliance in modern households. A heating tube is installed in the box. The overall size of the heating tube is large and it is usually installed on the top. One end of the heating tube is electrically connected to the box, and the rest is in a cantilever state, so it needs to be further fixed in the box. The existing oven heating tube fixing method is relatively simple, such as using screws to fix it directly to the box, or using longer and more solid support bars to hold up the heating tube, and the two ends of this longer and more solid support bar need to support the two sides of the box. The above fixing methods have common defects, such as the enamel surface of the box is easily damaged during the fixing process, which increases the defective rate; the fixing method is more complicated, which increases the difficulty of assembly; in order to ensure that the heating tube is firmly fixed, the support bar cannot be too short, so the material cost is also increased. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an oven heating tube installation structure which has a simple and reasonable structure, reliable heating tube fixation and convenient installation.

[0004] The utility model achieves the above purpose by:

[0005] The utility model discloses an oven heating tube installation structure, comprising a clamping ring, wherein the inner hole edge of the clamping ring extends upward to form a clamping tube, the outer edge of the clamping ring extends downward to form a supporting tongue, and the upper edge of the clamping tube is provided with a clamping ear protruding outwards.

[0006] Furthermore, the free end of the support tongue is folded upward to form a slot.

[0007] Furthermore, it also includes a box body, a mounting hole is opened on the top of the box body, and a notch is opened on the edge of the mounting hole for the ear to pass through.

[0008] Furthermore, a limit platform is protruded outwardly from the mounting hole and can limit the rotation of the ear.

[0009] Furthermore, the middle section of the support bar is bent downward to form a U-shaped clamping portion, and the U-shaped clamping portion is adapted to the clamping groove.

[0010] Furthermore, a steam exhaust pipe is fixed inside the clamping pipe.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0020] Please refer to Figures 1 to 6 , shows an oven heating tube installation structure, including a clamping ring 2, the inner hole edge of the clamping ring 2 extends upward to form a clamping tube 21, the outer edge of the clamping ring 2 extends downward to form a tongue 22, and the upper edge of the clamping tube 21 is provided with an outwardly protruding clamping ear 23.

[0021] As shown in the accompanying drawings, this embodiment provides a specific structure of a clamp ring 2 that can be used to hold up the heating tube of the oven. The function of the clamp ring 2 is to be installed on the inner wall of the box, and to stably hold up the heating tube assembly in the box through the tongue 22 extending from the outer edge of the clamp ring 2. When using this clamp ring 2, it is necessary to open a mounting hole in the oven in advance. Since there is a clamp ear 23 on the upper edge of the clamp tube 21, the clamp tube 21 can be installed in the mounting hole from the inside of the oven to the outside, and then clamped by the clamp ear 23. Such a structure does not require the use of accessories such as screws, and the installation is very simple and convenient. At the same time, since the mounting hole of the oven is pre-processed and surface-treated before use, it is not necessary to damage the enamel surface layer inside the oven when installing the clamp ring 2. Example

[0022] The free end of the support tongue 22 is folded upward to form a locking groove 24 .

[0023] As shown in the drawings, the tongue 22 can be made of a thin plate, and the slot 24 is an upper open structure, so it has a certain elasticity and can be used to clamp tubular parts such as heating tubes. The clamping is more stable and reliable, and can prevent them from moving or being damaged due to collision. Example

[0024] The box body 1 is also included. A mounting hole 11 is formed on the top of the box body 1 . A notch 12 is formed at the edge of the mounting hole 11 for the ear 23 to pass through.

[0025] As shown in the accompanying drawings, a specific structure for installing a clamping ring and a box body is provided, wherein a mounting hole 11 is opened at the top of the box body 1, and a clamping tube 21 of the clamping ring 2 passes through the mounting hole 11 from the inside of the box body 1, wherein a notch 12 is provided for a clamping ear 23 to pass through, and after the clamping ear 23 passes through, the clamping ring 2 is rotated as a whole at an angle so that the clamping ear 23 is rotated away from the notch 12, so that the upper surface of the ring body of the clamping ring 2 is tightly attached to the inner wall of the box body 1, and the clamping ear 23 is tightly clamped on the outer wall of the box body 1, and the clamping ring 2 is firmly fixed in the mounting hole 11 through the clamping structure of the clamping ear 23 and the ring body of the clamping ring 2, and the installation is very convenient. Example

[0026] A limiting platform 13 is protruded outwardly from the mounting hole 11 and can limit the rotation of the latch 23 .

[0027] As shown in the drawings, the ear 23 and the notch 12 on the mounting hole 11 and the limit platform 13 are symmetrically distributed, and the limit platform 13 is located between the two notches 12. During installation, the clamp ring 2 is rotated so that the ear 23 stops when rotating the limit platform 13, which is convenient for the operator to feel. Example

[0028] It also includes a heating tube 3 and a support bar 4 fixed in the middle of the heating tube 3. The support tongue 22 is made of a thin plate, and the opening width of the slot 24 is smaller than the slot width.

[0029] As shown in the attached drawings, the heating tube 3 and the support bar 4 form a heating tube assembly, wherein the heating tube 3 is a disc-shaped one whose outer contour is bent and adapted to the top of the box body, and has a large span. The support bar 4 spans across all parts of the entire heating tube 3 and is fixed as a whole by a connector. Since the tongue 22 is made of a thin plate, the wall of the card slot 24 has a certain elasticity, and the middle section of the support bar 4 can be slightly opened and entered when it is inserted from the opening. After entering the card slot 24, the opening width is restored, so that the support bar 4 is not easy to fall out, thereby achieving the function of fixing the heating tube 3. At the same time, since the support bar 4 is fixed as a whole with the entire heating tube, it is adapted to the top of the inner cavity of the box body and is not easy to rotate. Therefore, this fixing method of the support bar 4 plus the heating tube 3 plus the clamping ring 2 can also prevent the clamping ring 2 fixed in the mounting hole of the box body from falling out due to unnecessary rotation. Example

[0030] The middle section of the support bar 4 is bent downward to form a U-shaped clamping portion 41 , and the U-shaped clamping portion 41 is adapted to the clamping slot 24 .

[0031] As shown in the attached drawings, since the tongue 22 of the clamp ring 2 is bent downward, the slot 24 thereon is at a distance from the top of the box, which makes it easy to operate during installation, and the U-shaped clamping portion 41 is in the middle of the support bar 4 and is bent downward. After it is clamped into the slot 24, the rest of the support bar 4 is closer to the top of the box. Therefore, when the heating tube 3 is fixed under the support bar 4, the heating tube 3 can also be closer to the top of the box, which is conducive to fully using the internal space of the box. At the same time, due to the large span, the strength of the support bar 4 is not good, and the U-shaped joint 41 also plays a role in strengthening the strength of the entire support bar 4, killing two birds with one stone. Example

[0032] An exhaust pipe 5 is also fixed inside the clamping pipe 21 .

[0033] As shown in the drawings, the exhaust pipe 5 can be installed in the clamping pipe 21 by riveting, so that the exhaust pipe 5 and the clamping ring 2 are connected as a whole, which can not only exhaust steam but also make the structure of the clamping ring 2 more stable and reliable.
