The locking assembly 32 includes a locking piece 321 and a torsion spring 322. The locking piece 321 is rotatably connected to the bracket 1. The torsion spring 322 is disposed between the bracket 1 and the locking piece 321. The locking piece 321 is provided with a locking hook 3211 that cooperates with the flange 21. The torsion spring 322 acts on the locking piece 321 so that the locking hook 3211 always has a tendency to move toward the inside of the installation space. The locking assembly 32 also includes a rotating shaft 323. The torsion spring 322 is sleeved on the rotating shaft 323. A sliding protrusion 3212 is provided on the side of the locking piece 321 close to the bracket 1. The bracket 1 is provided with a fan-shaped hole 3213 that is slidably engaged with the sliding protrusion 3212. The fan-shaped hole 3213 is arranged to extend along the circumference of the rotating shaft 323. A plurality of the card slots 31 are disposed on the inner side of the bracket 1 . The plurality of the card slots 31 are disposed at the same height. The locking assembly 32 is located beside one of the card slots 31 .

[0040] Based on the above embodiments, the present invention aims to provide a gas tank installation structure for a gas furnace, including a bracket 1 and a gas tank 2, wherein an installation space for accommodating the gas tank 2 is formed in the bracket 1, and a convex edge 21 is circumferentially arranged at the bottom of the gas tank 2, and the bracket 1 is provided with an inverted installation mechanism 3, wherein the inverted installation mechanism 3 includes a card slot 31 circumferentially arranged on the inner side of the bracket 1, and the card slot 31 is engaged with the convex edge 21 to enable the gas tank 2 to be invertedly installed in the installation space, and the inverted installation mechanism 3 also includes a locking assembly 32 engaged with the convex edge 21, and the locking assembly 32 is used to prevent the convex edge 21 from falling off from the card slot 31. A positive assembly 4 is also included, and the positive assembly 4 includes a connecting member 41 fixedly connected to the bracket 1 and a connecting head 42 fixedly connected to the gas tank 2, and the connecting head 42 is slidably connected to the connecting member 41. The forward installation assembly 4 can realize the forward installation of the gas cylinder 2, which is suitable for the installation of a new gas cylinder 2; the inverted installation mechanism 3 can realize the inverted installation of the gas cylinder 2, which is suitable for when the gas in the gas cylinder 2 is more than half used or when the firepower needs to be increased. Figure 7 As shown, the outer wall of the lock hook 3211 is set as an arc surface 32111, and the setting of the arc surface 32111 facilitates the convex edge 21 to be stuck in the lock hook 3211 when the gas cylinder 2 is installed upside down. Figure 1 and Figure 2As shown, first insert the convex edge 21 on one side of the gas tank 2 into the slot 31 opposite to the lock hook 3211, then lift the gas tank 2 so that the convex edge 21 on the other side of the gas tank 2 passes over the arc surface 32111 of the lock hook 3211 and then inserts into the lock hook 3211. The lock hook 3211 applies a clamping force to the convex edge 21 of the gas tank 2 under the elastic force of the torsion spring 322, so that the gas tank 2 is stably clamped in the slot 31 and the lock hook 3211. When it is necessary to disassemble the gas tank 2, pull the lower end of the locking plate 321 to rotate in a direction away from the gas tank 2 until the lock hook 3211 is disengaged from the convex edge 21. At this time, the convex edge 21 can be taken out from the slot 31 to complete the disassembly of the gas tank 2. In this embodiment, the openings of the slot 31 and the lock hook 3211 are both arranged to face obliquely upward. The slot 31 and the lock hook 3211, which are opened obliquely upward, provide support for the flange 21 after being clamped. In a further preferred embodiment, the opening width and the curvature of the inner wall of the slot 31 and the lock hook 3211 are adapted to the thickness of the flange 21 of the gas tank 2 and the curvature of the outer wall of the flange 21. In this embodiment, the rotation trajectory of the locking piece 321 is restricted by the sliding cooperation between the fan-shaped hole 3213 and the sliding protrusion 3212.

[0041] As another preferred embodiment of the present invention, it further includes a front-mounted assembly 4, which includes a connector 41 fixedly connected to the bracket 1 and a connector head 42 fixedly connected to the gas tank 2, and the connector head 42 is slidably connected to the connector 41. The connector 41 is provided with a sliding interface 411, and the connector head 42 is provided with a sliding groove 421 that is slidably matched with the sliding interface 411. Both sides of the mouth of the sliding interface 411 of the connector 41 are provided with upwardly protruding bending portions 412, and the bending portions 412 are used to limit the sliding out of the connector head 42. In this embodiment, as Figures 2 to 6 As shown, the gas tank 2 can be quickly installed forwardly through the connector 42 and the connector 41. When installing the gas tank 2 forwardly, the connector 42 is installed into the sliding interface 411 of the connector 41, so that the sliding interface 411 is inserted into the sliding groove 421. At this time, the bending parts 412 on both sides of the mouth of the sliding interface 411 of the connector 41 limit the connector 42 to prevent the connector 42 from slipping out. When the gas tank 2 needs to be disassembled, the connector 42 is lifted upward so that the sliding groove 421 of the connector 42 is free from the restriction of the bending part 412, and the connector 42 is moved outward.

[0042] like Figure 1 and Figure 3As shown, another object of the utility model is to provide a gas stove 100 using the above-mentioned gas tank installation structure of a gas stove, wherein the gas stove 100 includes a spray plate 101, wherein the spray plate 101 is arranged on the top of the bracket 1, and the gas tank 2 is connected to the spray plate 101 through a pipeline. A fire regulating valve 102 is arranged between the spray plate 101 and the gas tank 2, and a preheating pipe 103 extending into the spray plate 101 is arranged on the fire regulating valve 102, wherein one end of the preheating pipe 103 is connected to the air inlet port of the fire regulating valve 102, and the other end of the preheating pipe 103 is connected to the air outlet port of the fire regulating valve 102. In this embodiment, the gas stove 100 can realize the forward installation of the gas tank 2 through the forward assembly 4, and can realize the inverted installation of the gas tank 2 through the inverted mechanism 3, thereby increasing the applicability of the gas stove 100. In a further embodiment, the preheating pipe 103 is provided to allow the liquefied gas to flow out in a liquid state for preheating and vaporization, which greatly reduces the effect of the gas tank 2 temperature reduction caused by the vaporization of the liquefied gas in the gas tank 2, resulting in a reduction in firepower. Such a gas stove 100 can output stable high power, making cooking faster and more efficient. The firepower regulating valve 102 can adjust the gas output volume, and increase the firepower when necessary, making cooking faster and more efficient.

[0043] As another preferred embodiment of the present invention, the bracket 1 comprises an upper bracket 11 and a lower bracket 12 which are foldably connected, and a telescopic extension tube 121 is provided at the lower end of the lower bracket 12. In this embodiment, the upright assembly 4 and the inverted assembly 3 are both provided on the upper bracket 11. In this embodiment, Figure 8 As shown, the foldable structure of the bracket 1 can realize the folding storage of the gas stove 100 when the gas stove 100 is not in use, so that the overall size of the gas stove 100 is small, which is convenient for storage and carrying. The installation height of the gas stove 100 when in use can be adjusted by setting the extension tube 121, thereby improving the convenience and comfort of using the gas stove 100.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
