Description of Related Art

With the rise of lobsters in recent years, stoves for cooking lobsters have been gradually accepted. Generally, the stoves for cooking lobsters are very heavy due to their large barrel, so an external air cylinder is adopted by most manufacturers and is directly placed on the ground, which makes it very inconvenient to move the ovens by users. Some manufacturers have designed a tray connected to one side of the oven frame to store the air cylinder to ensure that the gas cylinder can be moved along with the frame of the stoves.

However, considering that the temperature around the stove during operation is very high due to the high power of the stoves, generally hundreds of thousands of British thermal unit (BTU), the tray should be kept away from the frame, which makes the whole oven occupy too much space. When no cylinder is placed on the tray, the tray connected to the frame not only occupies a lot of space, but also may trip people and cause injuries, and the tray is inconvenient to disassemble and may be damaged due to repeated assembly and disassembly.

DESCRIPTION OF THE EMBODIMENTS

The invention will be explained in further detail below in conjunction with the accompanying drawings and embodiments, but the invention is not limited to the following description.

As shown in FIG. 1 and FIG. 2, a foldable tray device for a gas cylinder of a stove comprises a tray body 1, a connecting rod 2 and a base 3. A plurality of universal wheels 4 are arranged at a lower end of the tray body 1. One end of the connecting rod 2 is fixed to a side wall of the tray body 1, and another end of the connecting rod 2 is hingedly coupled to the base 3. A locking mechanism 50 is arranged between the another end of the connecting rod 2 and the base 3, and a fixing mechanism 6 configured to be connected to a frame of the stove is arranged on the base 3.

As shown in FIG. 3 to FIG. 5, coupling holes 31 are formed in the base 3, a mounting hole 21 is formed in the connecting rod 2, and the coupling holes 31 and the mounting hole 21 are connected through a hinge pin 22. In this way, the connecting rod 2 can smoothly rotate around the coupling holes 31.

The locking mechanism 50 comprises a button pin 51 mounted on the connecting rod 2. First positioning holes 32 and second positioning holes 33 are formed in the base 3. A connecting line between each of the first positioning holes 32 and a corresponding one of the coupling holes 31 is perpendicular to a connecting line between each of the second positioning holes 33 and a corresponding one of the coupling holes 31. That is, the abovementioned connecting lines have a 90° angle therebetween. Specifically, as shown in FIG. 4, on one side of the base 3, a line connecting the coupling hole 31 and the first positioning hole 32 is perpendicular to a line connecting the coupling hole 31 and the second positioning hole 33. When the button pin 51 is located in the first positioning holes 32, the connecting rod 2 is in a horizontal state, as shown in FIG. 1. When the button pin 51 is located in the second positioning holes 33, the connecting rod 2 is in a vertical state, as shown in FIG. 2.

In this structure, the button pin 51 can be pressed to retreat back into the connecting rod 2 to unlock the connecting rod 2 from the base 3, such that the connecting rod 2 can rotate freely to be folded and stored. When the button pin 51 is aligned to the first positioning holes 32 or the second positioning holes 33, the button pin 51 can stretch out automatically to be clamped in the first positioning holes 32 or the second positioning holes 33 to lock the connecting rod 2 to the base 3. The automatic stretching of the button pin 51 is mainly performed by means of a V-shaped elastic member. The V-shaped elastic member is mounted in the connecting rod 2 and has one end abutting against an inner wall of the connecting rod 2, and the button pin 51 is fixed to the other end of the V-shaped elastic part. When the button pin 51 is pressed, one end of the elastic part moves inwards under the effect of a force to drive the button pin 51 to retreat back into the connecting rod 2. When released, the button pin 51 rebounds automatically under the effect of the elastic force of the elastic part to stretch out of the connecting rod 2 again.

As shown in FIGS. 3-5, the fixing mechanism 6 comprises a fixing plate 61, an L-shaped plate 62 and lock bolts 63. The fixing plate 61 is fixed to a side wall of the base 3, the L-shaped plate 62 is fixed to an upper end of the fixing plate 61, a clamping space 64 is formed between the L-shaped plate 62 and the fixing plate 61, and the lock bolts 63 are mounted on the L-shaped plate 62. In this structure, the clamping space 64 formed between the L-shaped plate 62 and the fixing plate 61 is matched with a frame of the stove, such that the whole base 3 can be disposed on the frame of the stove. The lock bolts 63 can further lock the L-shaped plate 62 on the frame to realize reliable connection.

A plurality of supports 11 are fixed to the side wall of the tray body 1, and the plurality of universal wheels 4 are respectively fixed to the supports 11 in a one-to-one correspondence manner. In this structure, the universal wheels 4 are detachably connected to the corresponding supports 11 through bolts, so that connection is reliable, and later maintenance is facilitated.

A gas tube bracket 12 is fixed to a side wall of one support 11. A gas tube (not shown) can be disposed on the gas tube bracket to be stored in order and prevented from being in a mess.

An accommodating cavity 13 is formed in the tray body 1 and vertically penetrates through the tray body 1, a butterfly bolt 14 is screwed on at least one of the supports 11, a tail end of the butterfly bolt 14 sequentially penetrates through the support 11 and the tray body 1 to extend into the accommodating cavity 13, and a contact piece 15 is fixed to the tail end of the butterfly bolt 14. By adoption of this structure, the butterfly bolt 14 can be adjusted to enable the contact piece 15 to contact with a gas cylinder, such that the tray device can adapt to gas cylinders of different specifications, and the gas cylinder is prevented from shaking excessively.

It should be noted that the above embodiments are merely preferred ones of the invention, and are not intended to limit the protection scope of the patent of invention. Material and structure improvements of the components mentioned above, or substitutions with technical equivalents can be made to the invention. All equivalent structural variations obtained according to the contents of the specification and the drawings of the invention, or direct or indirect applications to other relating technical fields should also fall within the scope of the invention.
