[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0034] Embodiment 1:

[0035] The utility model provides a flip-top fuel lighter, referring to Figures 1 to 11 As shown, the flip-top fuel lighter comprises a body 1 , a cover 2 and a double-dial locking mechanism 3 .

[0036] The cover 2 is arranged on the body 1 in a flippable manner, and the double-dial locking mechanism 3 is arranged on the body 1 and located on the inner side of the cover 2. The double-dial locking mechanism 3 is used to lock the cover 2 into a closed state.

[0037] The dual-dial locking mechanism 3 includes a bracket 31 and two dial wheels 32. The two dial wheels 32 are rotatably arranged on the bracket 31. The two dial wheels 32 are arranged opposite to each other. A clamping portion 321 is arranged on the opposite side of the two dial wheels 32. A toggle portion 322 is arranged on the opposite side of the two dial wheels 32. A clamping portion 21 is arranged at a position on the cover 2 corresponding to the clamping portion 321.

[0038] When not in use, the flip cover 2 is in a closed state, the corresponding engaging portion 321 is engaged with the engaging portion 21 , and the cover 2 is firmly locked in the closed state.

[0039] When opening the cover, the moving parts 322 of the two dial wheels 32 are moved respectively to separate the corresponding engaging parts 321 from the engaging parts 21 , and at this time, the locking state is released.

[0040] In the above process, a double clamping structure is formed between the double dial locking mechanism 3 arranged on the body and the cover 2. The double locking method can firmly lock the cover 2 to the closed state, avoid the occurrence of accidental opening of the cover, and improve the safety and reliability of use.

[0041] Embodiment 2:

[0042] Example 2 is based on Example 1:

[0043] like Figures 1 to 11 As shown, the dual-dial locking mechanism 3 includes two return elastic members 33 , one end of the return elastic member 33 is connected to the bracket 31 , and the other end of the return elastic member 33 is connected to the corresponding dial 32 .

[0044] During the process of opening the cover, the dial wheel 32 is rotated, and the dial wheel 32 pushes the return elastic member 33 to deform. When the cover opening action is completed, the user's driving force on the dial wheel 32 is eliminated, and the dial wheel 32 automatically returns to its initial position under the action of the return elastic member 33.

[0045] As an optional implementation, two mounting posts 311 are vertically disposed on the bracket 31 , and the two dial wheels 32 are rotatably disposed on the two mounting posts 311 , respectively.

[0046] A receiving groove 325 is axially provided at the bottom of the dial wheel 32, and the mounting column 311 is located in the receiving groove 325. A column hole is axially provided through the dial wheel 32, and the column hole passes through the receiving groove 325. The mounting column 311 is inserted into the column hole and cooperates with the gap of the column hole, which can effectively ensure the rotation effect of the dial wheel 32.

[0047] The return elastic member 33 is configured as a first torsion spring, which is sleeved on the corresponding mounting column 311 , and whose two ends are respectively in contact with the bracket 31 and the corresponding dial wheel 32 . When the dial wheel 32 is rotated, the first torsion spring can be twisted, thereby generating deformation.

[0048] As an optional implementation, the clamping portion 321 is configured as a clamping slot, and an inclined boss 323 is provided on the dial wheel 32 at a notch position of the clamping slot, and an inclined surface 3231 is provided on the inclined boss 323 .

[0049] The engaging portion 21 is configured as a hook, and a position of the hook corresponding to the inclined boss 323 is configured as an inclined abutting surface 211 , and the inclined abutting surface 211 is matched with the inclined surface 3231 .

[0050] When the cover 2 is closed, the inclined abutting surface 211 presses against the inclined boss 323 and pushes the dial 32 to rotate, so that the hook slides and engages in the slot, thereby locking the cover 2.

[0051] The arrangement of the inclined boss 323 and the inclined abutting surface 211 facilitates the snap-fit operation and makes closing the cover more labor-saving and convenient.

[0052] As an optional embodiment, a limiting portion 324 is provided on the dial wheel 32. The limiting portion 324 is located at the bottom of the dial wheel 32 and is an arc-shaped limiting strip arranged along the bottom edge of the dial wheel 32. A first positioning portion 312 and a second positioning portion 313 are provided on the bracket 31. The first positioning portion 312 and the second positioning portion 313 are positioning blocks.

[0053] The limiting portion 324 is located between the first positioning portion 312 and the second positioning portion 313 . In an initial state, the limiting portion 324 abuts against the first positioning portion 312 . When the dial 32 is rotated, the limiting portion 324 can abut against the second positioning portion 313 .

[0054] The setting of the limiting part and the positioning part can limit the rotation direction of the dial wheel 32 on the one hand, and limit the maximum rotation angle of the dial wheel 32 on the other hand.

[0055] Preferably, the two dial wheels 32 are centrally symmetrical, so that the two dial wheels 32 rotate in opposite directions. When opening the cover, the user twists the two dial wheels 32 with his hands to make the two dial wheels 32 rotate synchronously in opposite directions, which is convenient for operation.

[0056] As an optional embodiment, a mounting protrusion 11 is provided on the fuselage 1, a receiving cavity is provided inside the mounting protrusion 11, two clearance grooves 111 are relatively provided on the side walls of the mounting protrusion 11, the clearance grooves 111 are communicated with the receiving cavity, the double dial locking mechanism 3 is installed in the receiving cavity, the driving part 322 of the dial wheel 32 passes through the corresponding clearance groove 111, and is placed outside the receiving cavity.

[0057] A transition groove 112 is provided at the top of the mounting protrusion 11 in communication with the accommodating cavity. The engaging portion 21 can be inserted into the accommodating cavity along the transition groove 112 and engaged with the engaging portion 321 .

[0058] As an optional implementation, a cover-opening elastic member 13 is provided on the body 1 , and two ends of the cover-opening elastic member 13 are connected to the body 1 and the cover 2 respectively.

[0059] When not in use, the cover 2 is in a closed state, and the cover-opening elastic member 13 is in a deformed state.

[0060] When in use, the two dial wheels 32 are rotated to separate the corresponding engaging portions 321 from the engaging portions 21 , and the deformed cover-opening elastic member 13 can drive the cover 2 to open.

[0061] The arrangement of the cover-opening elastic member 13 enables the cover to be automatically opened when the locking state of the cover 2 is released, further facilitating the operation.

[0062] As an optional implementation, the flip-top fuel lighter includes an ignition mechanism 4 and a grinding wheel mechanism 5 arranged on the body 1 .

[0063] The ignition mechanism 4 includes a flint assembly and ignition cotton, and the grinding wheel mechanism 5 includes a rotatable grinding wheel 51. The flint assembly is located below the grinding wheel 51 and contacts the grinding wheel 51. One end face of the grinding wheel 51 is a friction surface, and the friction plate is frictionally connected to the machine cover 2.

[0064] When the cover 2 is opened, the cover 2 drives the grinding wheel 51 to rotate through friction, so that the grinding wheel mechanism 5 and the flint assembly generate sparks due to friction difference, and ignite the ignition cotton. In this way, ignition can be achieved while the cover is opened, and the operation is extremely convenient.

[0065] The flint assembly and the ignition cotton are both prior art, and their detailed structures are not described in detail.

[0066] As an optional embodiment, a fixed shaft 12 is provided on the fuselage 1, and the cover 2 can be flipped and covered on the fuselage 1 through the fixed shaft 12.

[0067] The cover opening elastic member 13 is configured as a second torsion spring, the fixed shaft 12 passes through the second torsion spring, and the two ends of the second torsion spring respectively abut against the body 1 and the cover 2; the use of the second torsion spring has a simple structure and a significant cover flipping effect.

[0068] As an optional implementation, the grinding wheel 51 is provided with a mounting groove extending therethrough in the axial direction, and the grinding wheel 51 can be rotatably sleeved on the second torsion spring through the mounting groove.

[0069] In this way, the structure is made more compact while ensuring the flipping effect.

[0070] As an optional embodiment, the grinding wheel mechanism 5 includes a pawl 52 , which is arranged on the machine body 1 , and a plurality of ratchet teeth 511 are evenly arranged along the circumferential direction on the end surface of the other end of the grinding wheel 51 , and the ratchet teeth 511 and the pawl 52 are matched.

[0071] When in use, the cover 2 is opened, and the grinding wheel 51 is driven to rotate forwardly by friction. At this time, the pawl 52 and the ratchet 511 slide relative to each other, which will not prevent the grinding wheel 51 from rotating, thereby ensuring the ignition effect.

[0072] In actual use, when the grinding wheel 51 is reversely turned due to an erroneous operation, the ratchet pawl 52 abuts against the ratchet teeth 511 , thereby preventing the grinding wheel 51 from rotating in the reverse direction.

[0073] The pawl 52 and the ratchet 511 cooperate with each other to limit the grinding wheel 51 to only one-way rotation, which can reduce the accidental friction between the grinding wheel 51 and the flint assembly, and effectively extend the service life of the grinding wheel 51 and the flint assembly while ensuring safety in use.
