If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0032] As Figures 1 to 4 shown, the quick mounting structure of the box body according to the first aspect embodiment of the present invention includes a bottom cover 100, a lock block 210, and a box body 300. Among them, the bottom cover 100 can be the bottom cover 100 of any household appliance, the lock block 210 is cylindrical, and since the box body 300 is used as a battery box or a control box of a household appliance, the shape of the box body 300 is generally a rectangular body, but other shapes are not excluded. As Figure 5 shown, the bottom cover 100 is provided with a first through hole 110 and a second through hole 120. The first through hole 110 is located beside the second through hole 120. The first through hole 110 is used to install the lock block 210, and the second through hole 120 is used to install the box body 300. Specifically, the first through hole 110 is composed of a round hole 111 and a long hole 112. The diameter of the round hole 111 is greater than the width of the long hole 112. However, the present invention does not limit the specific shape of the first through hole 110. As long as the first through hole 110 includes the round hole 111 and the long hole 112, no matter what the shape of the first through hole 110 is, it belongs to the protection scope of the present invention; the shape of the second through hole 120 is the same as the shape of the box body 300. When the shape of the box body 300 is a rectangular body, the shape of the second through hole 120 is rectangular, and the size of the second through hole 120 is not less than the size of the box body 300 so that the box body 300 can pass through the second through hole 120.

[0033] As Figure 3 , Figure 4 and Figure 6As shown, a convex block 211 is provided on the outer peripheral surface of the lock block 210 along the central axis direction. The outer peripheral surface of the convex block 211 is an arc surface. The protruding height of the convex block 211 should be kept within a suitable range as much as possible. In the present invention, the percentage of the protruding height of the convex block 211 in the diameter of the lock block 210 is preferably 5%-10%. At the same time, an eccentric shaft 220 is fixedly connected to the lower bottom surface of the lock block 210. The eccentric shaft 220 is arranged in the first through hole 110, that is, the eccentric shaft 220 can only rotate in the first through hole 110. The eccentric shaft 220 is fixedly connected with a rotating handle 230. The rotating handle 230 can drive the lock block 210 to perform eccentric rotation around the eccentric shaft 220. The lock block 210, the eccentric shaft 220 and the rotating handle 230 together constitute an eccentric lock. When the eccentric lock is installed on the first through hole 110, the lock block 210 and the rotating handle 230 are respectively located above and below the bottom cover 100. Specifically, the rotating handle 230 includes a limiting portion 231 and a handle portion 232. The limiting portion 231 is fixedly connected with the eccentric shaft 220, and the size of the limiting portion 231 is larger than the size of the eccentric shaft 220. In order to facilitate the disassembly and assembly of the eccentric lock, the size of the first through hole 110 is not less than the size of the rotating handle 230, that is, the size of the round hole 111 is not less than the size of the limiting portion 231, the width of the long hole 112 is less than the size of the limiting portion 231, the width of the long hole 112 is not less than the width of the handle portion 232, and the length of the long hole 112 is not less than the length of the handle portion 232, so that the rotating handle 230 can pass through the first through hole 110.

[0034] As Figure 3 and Figure 4As shown, a limiting plate 310 is provided at the bottom of the box body 300. The size of the limiting plate 310 is larger than the size of the second through hole 120. When the box body 300 passes through the second through hole 120 from bottom to top, the limiting plate 310 is limited below the bottom cover 100. In order to enable the eccentric turn-lock to lock the box body 300, an avoidance groove 320 is formed on the outer side surface of the box body 300. The avoidance groove 320 is located above the limiting plate 310. The avoidance groove 320 is arranged opposite to the lock block 210. A limiting groove 321 is formed in the avoidance groove 320. The limiting groove 321 can accommodate the convex block 211. After-sales personnel can rotate the handle 230 to make the lock block 210 eccentrically rotate into the avoidance groove 320. Once the convex block 211 is rotated to be located in the limiting groove 321, at this time the eccentric turn-lock locks the box body 300, and vice versa to unlock the box body 300. Specifically, the cross-sectional shape of the avoidance groove 320 is arc-shaped. The diameter of the avoidance groove 320 is equal to or slightly larger than the diameter of the lock block 210. The rotation path of the central axis of the lock block 210 intersects with the central axis of the avoidance groove 320. When the central axis of the lock block 210 intersects with the central axis of the avoidance groove 320, the lock block 210 abuts against the avoidance groove 320 and the lock block 210 cannot continue to rotate. At this time, the convex block 211 is located in the limiting groove 321. Since the convex block 211 protrudes from the lock block 210, when the lock block 210 rotates, the convex block 211 has an interference fit with the avoidance groove 320. In order to reduce the displacement distance of the convex block 211 in the avoidance groove 320 and reduce the difficulty for after-sales personnel during locking or unlocking, the limiting groove 321 should be arranged close to the outer edge of the avoidance groove 320. The outer edge of the avoidance groove 320 is specifically the end close to the rotation direction of the lock block 210. It should be further noted that the position of the long hole 112 in the first through hole 110 should be arranged to ensure that when the eccentric shaft 220 is located at the end of the long hole 112, the eccentric turn-lock can lock the box body 300.

[0035] Since the present invention does not limit the eccentricity between the central axis of the lock block 210 and the eccentric shaft 220, the manufacturer can design the eccentricity according to the actual situation. In addition, the present invention does not limit the specific materials of the lock block 210 and the box body 300. The materials of the lock block 210 and the box body 300 include but are not limited to metal or plastic.

[0036] Such as Figure 2 and Figure 6As shown, in order to avoid interference between the handle portion 232 and the limit plate 310, the connecting lines of the positions of the bump 211, the eccentric shaft 220, and the handle portion 232 together form an angle a, and the angle of the angle a is greater than or equal to 45° and less than or equal to 225°. When the angle a is not within this range, the handle portion 232 and the limit plate 310 may interfere with each other, resulting in the eccentric rotary lock being restricted by the limit plate 310 and unable to lock the box body 300.

[0037] The gas stove according to the second aspect embodiment of the present invention includes the box body quick installation structure according to the first aspect embodiment of the present invention. The bottom cover 100 is a part of the outer shell of the gas stove, and the bottom cover 100 and the panel of the gas stove together form the outer shell of the gas stove. When after-sales personnel need to disassemble the box body 300 of the gas stove, they only need to rotate the rotating handle 230, and the rotating handle 230 drives the lock block 210 to perform eccentric rotation, so that the lock block 210 can be disengaged from the clearance groove 320 on the box body 300. At this time, the after-sales personnel can take out the box body 300 from below the bottom cover 100; when the after-sales personnel need to reinstall the box body 300 of the gas stove, first deflect the eccentric rotary lock by a certain angle to avoid the box body 300, then install the box body 300 from bottom to top onto the second through hole 120 of the bottom cover 100, and then rotate the rotating handle 230 to turn the lock block 210 into the clearance groove 320 of the box body 300. Finally, the bump 211 is located in the limit groove 321. At this time, the box body 300 is locked and fixed, and neither the box body 300 nor the eccentric rotary lock can fall off naturally. Compared with the prior art, the after-sales personnel can quickly disassemble and replace the box body 300 of the gas stove without disassembling the panel of the gas stove, and the fixing method of the box body 300 is also more firm, which can effectively reduce the probability of the box body 300 becoming loose during transportation.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
