Description

Technical Field

[0001] This application relates to the field of lighters, and in particular, to a lighter with a safety lock. Background Art

[0002] A lighter is a small fire-making device, mainly used for lighting fires, smoking, and also for cooking and other fire-making purposes. The main components of a lighter are a firing mechanism and a gas storage tank. When the firing mechanism operates, a spark is emitted and shoots towards the gas area to ignite the gas.

[0003] The gases used in lighters are mainly flammable gases, mostly butane, propane, and liquefied petroleum gas. They are pressurized and filled into the gas storage tank. Once released into the air, they absorb heat and vaporize, expanding rapidly and being extremely easy to ignite. Currently, common lighters include flint-wheel lighters, piezoelectric ceramic lighters, etc., and can be ignited by simply turning the steel wheel or pressing the pressing plate.

[0004] However, if a lighter is obtained by a child, it can also be easily lit, which may burn the child or ignite flammable items around, causing a fire, presenting a great potential safety hazard. Summary of the Utility Model

[0005] In order to prevent children from easily lighting the lighter and reducing the safety hazards of existing lighters, this application provides a lighter with a safety lock.

[0006] A lighter with a safety lock provided by this application adopts the following technical solution:

[0007] A lighter with a safety lock includes a lighter body, a safety cover, a locking component, and an unlocking component. The lighter body includes a tank body, a mounting block, a windproof cover, and a pressing block. The mounting block is fixedly connected to the top of the tank body. The windproof cover and the pressing block are respectively arranged at both ends of the top of the mounting block. The safety cover is hinged to the mounting block and sleeved on the windproof cover and the pressing block. The locking component is arranged on the safety cover and is used to restrict the rotation of the safety cover. The unlocking component is arranged on the mounting block and is used to restore the safety cover to a rotatable state.

[0008] By adopting the above technical solution, if you want to use the lighter, you need to operate the unlocking component to release the restriction of the locking component on the safety cover, and then you can rotate the safety cover to expose the windproof cover and the pressing block. Pressing the pressing block can ignite the lighter. After use, rotate the safety cover to cover the windproof cover and the pressing block, and operate the locking component to fix the safety cover. Even if a child gets the lighter, they cannot easily open the safety cover, reducing the safety hazards of the lighter.

[0009] Optionally, the locking component includes a fixing post, a locking block, and a clamping spring. The fixing post passes through the side wall of the safety cover. A fixing groove for accommodating a partial embedding of the fixing post is formed on the mounting block. The locking block is arranged on the side wall of the fixing post. A clamping groove for accommodating the locking block is formed on the inner wall of the fixing groove. One end of the clamping spring is fixedly connected to the fixing post, and the other end is fixedly connected to the locking block.

[0010] By adopting the above technical solution, after the lighter is used up, rotate the safety cover to block the windproof cover and the pressing block. Press the locking block towards the direction close to the fixing post, and then press the fixing post so that the locking block and the fixing post are embedded into the fixing groove together. The locking block pops out under the elastic reset action of the clamping spring and is embedded into the clamping groove. The safety cover cannot rotate under the restriction of the fixing post, and even if a child gets the lighter, it cannot be lit.

[0011] Optionally, the unlocking component includes a rotating rod and an unlocking block. The rotating rod is embedded and rotatably connected to the mounting block. The unlocking block is threadedly connected to the rotating rod and is located on the side of the unlocking block away from the fixing post. The side wall of the unlocking block is in contact with the inner wall of the clamping groove.

[0012] By adopting the above technical solution, when the lighter needs to be used, rotate the rotating rod to drive the unlocking block to move towards the direction close to the locking block along the setting direction of the clamping groove, push the locking block out of the clamping groove. At this time, pull the fixing post away from the bottom of the fixing groove to make it withdraw from the fixing groove, and the safety cover returns to the rotatable state. Rotate the safety cover to expose the windproof cover and the pressing block, and then it can be used.

[0013] Optionally, one end of the fixing post is fixedly connected with a pressing plate. The pressing plate is arranged on the side of the safety cover away from the mounting block. A reset spring is arranged between the pressing plate and the safety cover. One end of the reset spring is fixedly connected to the pressing plate, and the other end is fixedly connected to the side wall of the safety cover.

[0014] By adopting the above technical solution, when the safety cover needs to be locked after the lighter is used up, press the locking block towards the direction close to the fixing post, and then press the pressing plate so that the locking block and the fixing post are embedded into the fixing groove together. At this time, the reset spring is in a compressed state; when the lighter needs to be used, rotate the rotating rod, and the unlocking block pushes the locking block out of the clamping groove. At this time, the fixing post will move away from the bottom of the fixing groove under the elastic reset action of the reset spring, and there is no need to manually pull the fixing post, which is more convenient to use.

[0015] Optionally, a torsion spring is arranged on the rotating rod. One end of the torsion spring is fixedly connected to the side wall of the rotating rod, and the other end is fixedly connected to the side wall of the mounting block.

[0016] By adopting the above technical solution, when the lighter needs to be used, rotate the rotating rod. The coil spring is in a deformed state, driving the unlocking block to move so as to push the locking block out of the clamping groove. After the fixing column exits from the fixing groove, release the rotating rod. The rotating rod will rotate in the reverse direction under the elastic reset action of the coil spring, thereby driving the unlocking block to move in the reverse direction and returning to the initial position, without affecting the locking of the safety cover.

[0017] Optionally, a rotating plate is fixedly connected to the end of the rotating rod away from [the relevant part not specified in the original].

[0018] By adopting the above technical solution, the user can drive the rotating rod to rotate by rotating the rotating plate, and the operation is more convenient and labor-saving.

[0019] Optionally, a guiding inclined surface is provided on the side wall of the unlocking block away from the clamping spring.

[0020] By adopting the above technical solution, when locking the safety cover, when pressing the pressing plate to embed the fixing column into the fixing groove, the side wall of the fixing groove will press the unlocking block in the direction close to the fixing column along the guiding inclined surface, without the need for the user to manually press, further improving the convenience of using the lighter.

[0021] Optionally, a telescopic rod is provided on the side wall of the fixing column. One end of the telescopic rod is fixedly connected to the fixing column, and the other end is fixedly connected to the locking block.

[0022] By adopting the above technical solution, when the unlocking block pushes the locking block, the locking block can move along the setting direction of the telescopic rod without skewing in other directions, ensuring the normal use of the safety cover.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the lighter is used up and the safety cover needs to be locked, press the pressing plate so that the locking block and the fixing column are embedded into the fixing groove together. At this time, the return spring is in a compressed state; when the lighter needs to be used, rotate the rotating rod, and the unlocking block pushes the locking block out of the clamping groove. At this time, the fixing column will move in the direction away from the bottom of the fixing groove under the elastic reset action of the return spring, making it more convenient to use;

[0025] 2. When the lighter needs to be used, rotate the rotating rod. The coil spring is in a deformed state, driving the unlocking block to move so as to push the locking block out of the clamping groove. After the fixing column exits from the fixing groove, release the rotating rod. The rotating rod will rotate in the reverse direction under the elastic reset action of the coil spring, thereby driving the unlocking block to move in the reverse direction and returning to the initial position, without affecting the locking of the safety cover;

[0026] 3. The locking block and the fixing post are connected by a clamping spring and a telescopic rod. When the unlocking block pushes the locking block, the locking block can move along the setting direction of the telescopic rod without skewing in other directions, ensuring the normal use of the safety cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following Figures 1 - 3 further describes the present application in detail.

[0032] Referring to Figure 1 、 Figure 2 and Figure 3 An embodiment of the present application discloses a lighter with a safety lock, which includes a lighter body 1, a safety cover 2, a locking assembly 3 and an unlocking assembly 4. The lighter body 1 includes a tank body 11, a mounting block 12, a windproof cover 13 and a pressing block 14. The tank body 11 and the mounting block 12 are both square bodies. The mounting block 12 is integrally formed on the top of the tank body 11. The windproof cover 13 and the pressing block 14 are respectively installed at both ends of the top of the mounting block 12. The safety cover 2 is sleeved on the windproof cover 13 and the pressing block 14. One end of the safety cover 2 is hinged to the mounting block 12. The locking assembly 3 is arranged on the safety cover 2, and the unlocking assembly 4 is arranged on the mounting block 12.

[0033] Referring to Figure 2 and Figure 3, the locking component 3 includes a fixing post 31, a locking block 32 and a clamping spring 33. The fixing post 31 is a long rectangular body. The fixing post 31 passes through the side wall of the safety cover 2. A fixing groove 121 for accommodating a part of the fixing post 31 to be embedded is formed on the side wall of the mounting block 12. A pressing plate 311 is fixedly connected to one end of the fixing post 31 away from the fixing groove 121. A relief groove 312 for accommodating the locking block 32 is formed on the side wall of the fixing post 31. In this embodiment, two locking blocks 32 are provided, and the two locking blocks 32 are respectively arranged on opposite sides of the fixing post 31. Similarly, two relief grooves 312 are also provided. Clamping grooves 122 for accommodating the locking blocks 32 are respectively formed on the opposite inner walls of the fixing groove 121. One end of the clamping spring 33 is fixedly connected to the inner bottom wall of the relief groove 312, and the other end is fixedly connected to the side wall of the locking block 32.

[0034] It should be noted that a guiding inclined surface is provided on the side wall of the locking block 32 away from the clamping spring 33. The guiding inclined surface inclines from the side close to the pressing plate 311 to the side far from the pressing plate 311 in the direction close to the clamping spring 33.

[0035] After the lighter is used up, rotate the safety cover 2 to block the windproof cover 13 and the pressing block 14. The user presses the pressing plate 311 to partially embed the fixing post 31 into the fixing groove 121. During the movement, the side wall of the fixing groove 121 presses the locking block 32 into the relief groove 312 along the guiding inclined surface, and the clamping spring 33 is in a compressed state. When the locking block 32 is aligned with the clamping groove 122, the locking block 32 will pop out under the elastic reset action of the clamping spring 33 and be embedded into the clamping groove 122, so that the fixing post 31 cannot withdraw from the fixing groove 121, thereby restricting the rotation of the safety cover 2. Even if a child gets the lighter, they cannot open the safety cover 2, let alone light the lighter.

[0036] Refer to Figure 1 and Figure 3 , the unlocking component 4 includes a rotating rod 41 and an unlocking block 42. In this embodiment, since two locking blocks 32 are provided, the rotating rod 41 is a bidirectional screw rod, which is embedded and rotatably connected to the mounting block 12. The rotating rod 41 is located below the fixing post 31, and its extending direction is perpendicular to the extending direction of the fixing post 31. The unlocking block 42 is a square plate. The unlocking blocks 42 correspond to the locking blocks 32 one by one, so two unlocking blocks 42 are also provided. One end of the unlocking block 42 is threadedly connected to the rotating rod 41, and the other end extends into the clamping groove 122. The opposite side walls of the unlocking block 42 are in contact with the opposite inner walls of the clamping groove 122.

[0037] One end of the rotating rod 41 exposed outside the mounting block 12 is fixedly connected to a rotating plate 5. A coil spring 6 is sleeved on the rotating rod 41. One end of the coil spring 6 is fixedly connected to the rotating rod 41, and the other end is fixedly connected to the side wall of the mounting block 12.

[0038] When the lighter needs to be used, the user can rotate the rotating plate 5, and the rotating rod 41 will rotate accordingly, driving the two unlocking blocks 42 to move along the setting direction of the clamping groove 122 toward the direction close to the fixed column 31, and push the two locking blocks 32 out of the clamping groove 122 to make them enter the yielding groove 312. At this time, the coil spring 6 is in a deformed state; the user pulls the fixed column 31 in the direction away from the inner bottom wall of the fixed groove 121 to make the fixed column 31 withdraw from the fixed groove 121. The safety cover 2 can rotate at this time, and the user releases the rotating plate 5. The rotating rod 41 will rotate in the opposite direction under the elastic reset action of the coil spring 6, thereby driving the unlocking block 42 to move in the opposite direction and return to the initial position, which will not affect the re-locking of the safety cover 2.

[0039] In order to improve the convenience of using the lighter, a return spring 7 is fixedly installed on the side wall of the pressure plate 311 close to the safety cover 2, one end of the return spring 7 is fixedly connected to the pressure plate 311, and the other end is fixedly connected to the side wall of the safety cover 2. Therefore, when the unlocking block 42 pushes the locking block 32 out of the clamping groove 122, the fixing column 31 will move in a direction away from the inner bottom wall of the fixing groove 121 under the elastic return action of the return spring 7, without the need for the user to pull it.

[0040] In addition, in order to prevent the locking block 32 from being offset when the unlocking block 42 pushes the locking block 32, and to avoid the locking block 32 being stuck in the engaging groove 122 or the making way groove 312 and unable to move, a telescopic rod 8 is passed through the engaging spring 33, one end of the telescopic rod 8 is fixedly connected to the inner bottom wall of the making way groove 312, and the other end is fixedly connected to the side wall of the locking block 32.

[0041] The implementation principle of a lighter with a safety lock in the embodiment of the present application is as follows: when the user has finished using the lighter and needs to use the lighter, the user rotates the safety cover 2 to block the windproof cover 13 and the pressing block 14, and presses the pressure plate 311 to make one end of the fixing column 31 and the locking block 32 enter the fixing groove 121 together. During the movement, the side wall of the fixing groove 121 presses the locking block 32 into the giving way groove 312 along the guiding inclined surface, and the clamping spring 33 is in a compressed state; when the locking block 32 is directly opposite to the clamping groove 122, the locking block 32 will pop out under the elastic reset action of the clamping spring 33, and be embedded in the clamping groove 122, so that the fixing column 31 cannot exit the fixing groove 121, thereby limiting the rotation of the safety cover 2. Even if a child gets the lighter, the safety cover 2 cannot be opened, let alone ignite the lighter, which greatly reduces the safety hazard of the lighter.

[0042] When the user needs to use the lighter again, he rotates the rotating plate 5, and the rotating rod 41 rotates accordingly, driving the two unlocking blocks 42 to move along the setting direction of the snap-fit ​​groove 122 toward the direction close to the fixed column 31, and pushing the two locking blocks 32 out of the snap-fit ​​groove 122 to make them enter the yielding groove 312. At this time, the coil spring 6 is in a deformed state; at the same time, the fixed column 31 will move in the direction away from the inner bottom wall of the fixed groove 121 under the elastic reset action of the reset spring 7, and exit the fixed groove 121. The safety cover 2 can be rotated at this time to expose the wind shield 13 and the pressing block 14.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
