Description

Technical Field

[0001] This utility model relates to the field of fuel supply device technology, and in particular to an easily detachable fuel box structure. Background Technology

[0002] Existing portable gas stoves, outdoor heating stoves, and small burners typically use separate fuel boxes or fuel canisters for easy carrying and fuel replacement.

[0003] The above-mentioned existing technical solutions have the following drawbacks: some fuel boxes use a threaded connection, which requires a large rotation stroke to complete the disassembly and assembly. In addition, the air pressure of the fuel box may change, and the operator needs a lot of force to unscrew it. Furthermore, the threads are prone to loosening or jamming due to wear. Utility Model Content

[0004] The purpose of this invention is to provide an easily detachable fuel box structure to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A detachable fuel box structure includes a housing with a completely open top. The front and rear end faces of the housing are higher than the left and right end faces. Each of the front and rear end faces of the housing has a first receiving groove, which is positioned laterally along its length. The right end of each first receiving groove is completely open. A cover plate is slidably installed within the first receiving groove. Hooks are symmetrically fixedly installed on the right end face of the cover plate. Locks are symmetrically fixedly installed on the top of the right end face of the housing, with each lock corresponding to one of the hooks. A second receiving groove is provided at each of the four corners of the inner bottom of the housing. A limiting device is fixedly installed within each of the second receiving grooves to secure the fuel box.

[0006] By adopting the above technical solution, the cover plate can slide left and right along the first receiving groove on the front and rear end faces of the housing. When the cover plate slides to the right until the hook at its right end corresponds to the locking position on the right end face of the housing, rotating the locking buckle will lock the hook, thereby closing the top opening of the housing. Conversely, after unlocking the locking buckle, sliding the cover plate to the left will open the top of the housing, facilitating quick loading and unloading of the fuel packaging box. At the same time, the limiting devices at the four corners of the bottom of the housing can firmly clamp the fuel packaging box placed inside the housing from four directions, effectively preventing the fuel packaging box from shaking or shifting during transportation or use, thus improving the stability and safety of the overall structure. Compared with the traditional threaded connection method, this structure, through the design of the sliding cover plate and locking buckle, significantly shortens the disassembly and assembly stroke. Operators do not need to exert great effort to rotate the fuel packaging box, effectively avoiding the loosening or jamming problems caused by thread wear, and greatly improving the ease of disassembly and reliability of the fuel box.

[0007] In a further embodiment, the latch includes a first base, a rotating shaft, a lock body, and a locking ring. The first base is fixedly installed at the top of the right end face of the housing. The top of the first base is provided with a first through hole that extends from front to back. The rotating shaft is rotatably installed in the first through hole. The axis of the rotating shaft is collinear with the axis of the first through hole. A tension spring is fixedly installed on the rotating shaft. The axis of the tension spring is collinear with the axis of the rotating shaft. Both ends of the rotating shaft are fixedly installed with the lock body. The bottom of the lock body is fixedly installed with the tension spring.

[0008] By adopting the above technical solution, when the cover needs to be locked, the operator can rotate the lock body around its pivot. At this time, the tension spring is stretched and stores elastic potential energy. Once the lock body has rotated to the appropriate angle, the hook on the cover is engaged with the locking ring at the bottom of the lock body. Then, the lock body is released, and under the restoring force of the tension spring, the lock body automatically returns to its original position and tightly engages the hook, achieving a secure connection between the cover and the housing. During unlocking, simply overcoming the elastic force of the tension spring by rotating the lock body allows the locking ring to separate from the hook, making the operation labor-saving and quick, further improving the efficiency of fuel box assembly and disassembly. Simultaneously, the tension spring ensures that the latch always applies a stable locking force to the hook, effectively preventing accidental loosening of the latch and enhancing the safety and reliability of the structure.

[0009] In a further embodiment, the limiting device includes a second base, a first connecting rod, a second connecting rod, and a third connecting rod. The second base is fixedly installed in a second receiving groove. The end of the second base away from the housing is the inner end, and the end of the second base close to the housing is the outer end. An integrally formed first protrusion is provided at the inner end of the second base, and an integrally formed second protrusion is provided at the outer end of the second base. The protrusion has a second through hole extending from front to back. The first connecting rod is slidably installed in the second through hole. A compression spring is provided at the inner end of the first connecting rod, and the axis of the compression spring is collinear with the axis of the first connecting rod. The second connecting rod is rotatably installed at the outer end of the first connecting rod, and the third connecting rod is rotatably installed at the outer end of the second connecting rod. The outer end of the third connecting rod is rotatably installed with the second protrusion.

[0010] By adopting the above technical solution, the impact of fuel packaging boxes during transportation is effectively buffered, and it can also adapt to the fixing needs of fuel packaging boxes of different specifications within a certain range, enhancing the versatility and stability of the limiting device. When the fuel packaging box needs to be removed, as the packaging box moves upward, the pressure on the third link disappears, the compression spring pushes the first link to slide outward, and drives the second and third links to return to their initial state for the next use.

[0011] In a further embodiment, the third link is fitted with an anti-slip sleeve.

[0012] By adopting the above technical solution, the anti-slip sleeve can increase the friction between the third link and the contact surface of the fuel packaging box. The anti-slip sleeve is made of elastic material, which can form a flexible protection for the surface of the fuel packaging box during the clamping process, avoiding scratches or damage to the surface of the fuel packaging box due to rigid contact, and extending the service life of the fuel packaging box.

[0013] In a further embodiment, support bases are fixedly installed at the four bottom corners of the housing.

[0014] By adopting the above technical solution, the support base can raise the entire housing, creating a certain gap between the bottom of the housing and the placement plane, effectively preventing the bottom of the housing from directly contacting a damp or uneven surface, and extending the service life of the fuel box.

[0015] In a further embodiment, vent holes are provided on both the left and right end faces of the housing.

[0016] By adopting the above technical solution, the vent can promptly discharge combustible gases or volatiles that may accumulate inside the casing, effectively reducing the gas concentration inside the casing and avoiding safety hazards such as combustion or explosion caused by excessive gas concentration, thus significantly improving the safety of the fuel box during use.

[0017] In summary, this utility model has the following beneficial effects: 1. The locking and hook design allows for quick locking and unlocking of the cover, effectively preventing it from accidentally sliding open during transportation or use; 2. The sliding design between the cover and the housing significantly shortens the disassembly and assembly stroke, reducing the physical exertion of operators. Operators only need to push the cover to achieve quick opening and closing, eliminating the need for cumbersome rotation operations, which greatly reduces the difficulty of operation and the physical exertion. 3. The limiting device enables automatic and stable clamping of the fuel packaging box placed inside the casing from four directions. Attached Figure Description
