DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0018] Embodiments of the present utility model: Figure 1-Figure 4 As shown, a support frame for a gas burner includes a base 1, a support tube 2 is fixedly provided on the base 1, a height adjustment assembly is rotatably installed on the upper end of the support tube 2, a lifting screw 3 is plugged into and slidably connected to the support tube 2, and the lifting screw 3 is threadedly connected to the height adjustment assembly, and a gas burner tray assembly is fixedly provided on the top of the lifting screw 3.

[0019] The base 1 is a disc-shaped base, and the bottom of the base 1 is preferably provided with a plurality of anti-skid protrusions 4, which are made of rubber. The anti-skid protrusions 4 can prevent the base 1 from sliding and ensure the stability of the support. The height of the lifting screw 3 can be adjusted by rotating the height adjustment component, thereby changing the height of the gas burner tray component, which is suitable for gas burners with different installation heights.

[0020] In a specific embodiment, the height adjustment assembly includes a cylindrical adjustment block 5, a handle 6 and a mounting tube 7. A first threaded hole 8 is axially opened on the cylindrical adjustment block 5. A mounting tube 7 is fixedly provided at the lower end of the height adjustment assembly. A ball bearing 9 is provided in the mounting tube 7. A limiting step 10 is fixedly provided on the outer wall of the support tube 2. The inner ring of the ball bearing 9 is interference fit with the outer wall of the support tube 2. A plurality of handles 6 are circumferentially evenly spaced on the outer wall of the mounting tube 7.

[0021] The first threaded hole 8 is threadedly matched with the lifting screw 3, the mounting tube 7 is sleeved on the upper end of the support tube 2, the outer ring of the ball bearing 9 is interference-fitted with the inner wall of the mounting tube 7, the inner ring of the ball bearing 9 is interference-fitted with the outer wall of the support tube 2, and the bottom surface of the inner ring of the ball bearing 9 is in contact with the limit step 10 on the support tube 2. The limit adjustment 10 is used to limit the position of the ball bearing 9 to prevent the ball bearing 9 from sliding down. The setting of the ball bearing 9 can make the cylindrical adjustment block 5 and the mounting tube 7 rotate smoothly and reduce friction.

[0022] Furthermore, a second threaded hole 11 is formed on the side wall of the mounting tube 7, and a locking screw 12 is threadedly connected to the second threaded hole 11. The locking screw 12 is used to lock the mounting tube 7 so that the mounting tube 7 cannot rotate, thereby locking the lifting screw 3.

[0023] Furthermore, the gas burner tray assembly includes an arc-shaped base support 13 , a first side baffle 14 and a second side baffle 15 , the bottom surface of the arc-shaped base support 13 is fixedly connected to the top end of the lifting screw 3 , and the first side baffle 14 and the second side baffle 15 are arranged on both sides of the arc-shaped base support 13 .

[0024] Since the bottom of the volute of the gas burner is arc-shaped, the utility model is provided with an arc-shaped base 13, which can better fit the bottom of the volute of the gas burner. The gas burner tray assembly can be designed as a fixed-size structure, and such a gas burner tray assembly can only be used for gas burners of fixed specifications. Of course, the gas burner tray assembly can also be designed as an adjustable structure, and the adjustable structure will be introduced below. In order to protect the volute of the gas burner, sponge pads are preferably pasted on the top surface of the arc-shaped base 13, the inner side surface of the first side baffle 14, and the inner side surface of the second side baffle 15.

[0025] In another embodiment, a plurality of mounting sleeves 16 are evenly arranged on the bottom surface of the arc-shaped base 13. In this embodiment, four mounting sleeves 16 are preferably arranged. A first connecting column 17 connected to the mounting sleeve 16 is fixedly provided on the first side baffle 14, and a second connecting column 18 connected to the mounting sleeve 16 is fixedly provided on the second side baffle 15. A third threaded hole 19 is axially provided on the first connecting column 17, and a step hole 20 is axially provided on the second connecting column 18. The second side baffle 15 is provided with a mounting hole 21 connected to the step hole 20, and a bolt 22 is installed in each second connecting column 18.

[0026] The first connecting column 17 and the second connecting column 18 in each mounting sleeve 16 are connected by a bolt 22. Through such a design, the distance between the first side baffle 14 and the second side baffle 15 can be changed, so as to clamp gas burners of different specifications, thereby improving the applicability of the utility model.

[0027] Working principle of the utility model: when in use, first loosen all the bolts 22, so that the distance between the first side baffle 14 and the second side baffle 15 is significantly larger than the width of the gas burner volute, then loosen the locking screw 12, rotate the cylindrical adjustment block 5 through the handle 6, so that the lifting screw 3 is raised until the arc-shaped base 13 is tightly pressed against the bottom of the gas burner volute, and then tighten the locking screw 12 so that the cylindrical adjustment block 5 cannot rotate. Then tighten all the bolts 22 so that the first side baffle 14 and the second side baffle 15 clamp the gas burner volute. In this way, most of the weight of the gas burner acts on the arc-shaped base 13 and is transferred to the ground, which effectively improves the stress condition at the gas burner connection flange and reduces the stress on the connecting bolts.

[0028] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
