Description

Technical Field

[0001] This utility model relates to the field of flamethrower technology, specifically a flamethrower that can be stood upright and prevented from tipping over. Background Technology

[0002] A flamethrower is a tool that produces a high-temperature flame by burning combustible gases (such as butane, propane, or a mixture of gases). It is typically used for directional heating, melting, welding, or cleaning operations. Its core function is to achieve efficient energy release through concentrated flame spray. It is widely used in various fields such as outdoor activities, industrial maintenance, and agricultural processing.

[0003] When using traditional outdoor flamethrowers, if they are dropped and placed upright, the small contact area between the bottom of the flamethrower and the surface on which it is placed, or the unevenness of the surface, cannot provide stable support. This makes the flamethrower prone to tipping over due to instability or external forces (such as wind), posing a risk of fuel leakage or igniting the surrounding environment, which is a certain safety hazard.

[0004] Therefore, this utility model provides a flamethrower that can stand upright and prevent tipping. Utility Model Content

[0005] This invention provides a flamethrower that can stand upright and prevent tipping, which has the advantages of stable placement and anti-tipping, thus solving the problem of traditional flamethrowers being prone to tipping over and significantly improving safety in outdoor scenarios.

[0006] To achieve stable placement and prevent tipping, this utility model provides the following technical solution: a vertical anti-tipping flame gun, including a fuel tank, an ignition and combustion assembly is provided at the upper end of the fuel tank, an external screw assembly is sleeved on the lower side of the outer end of the fuel tank, an adjusting sleeve is threaded onto the outer end of the external screw assembly, the lower end of the external screw assembly is flush with the bottom of the fuel tank and is secured with a retaining sleeve, and multiple connecting rods are fixedly connected at intervals around the retaining sleeve, and the outer ends of the multiple connecting rods are rotatably connected to support plates;

[0007] A rotating ring is rotatably sleeved on the lower outer periphery of the adjusting sleeve. Multiple connecting rods are rotatably connected at intervals to the outer end of the rotating ring. The lower end of each connecting rod is rotatably connected to a support plate.

[0008] As a preferred embodiment of this utility model, the first connecting rod is rotatably connected to the middle of the outer side of the upper end face of the support plate, and the second connecting rod is rotatably connected to the middle of the inner side of the support plate.

[0009] As a preferred technical solution of this utility model, the multiple support pieces are all fan-shaped with beveled edges, arranged in a ring around the sleeve, and when horizontally unfolded, their lower surfaces are flush with the lower surface of the sleeve.

[0010] As a preferred technical solution of this utility model, the lower end face of the connecting rod is provided with at least two arc-shaped grooves spaced apart, and a friction pad is fixedly embedded inside the groove.

[0011] As a preferred technical solution of this utility model, the external screw connection assembly includes two semi-screw sleeves with threads on their outer surfaces. The two semi-screw sleeves are combined to form a cylindrical shape that covers the outside of the fuel tank. An upper collar is fixedly connected to the upper end of each semi-screw sleeve. A groove is opened at the outer end of each of the two upper collars. The two grooves are interconnected and fitted with a clamp. The opening of the clamp is connected by a bolt.

[0012] As a preferred technical solution of this utility model, two plug-in posts are fixedly connected to the lower end of the joint of one half-screw sleeve, and two plug-in grooves are opened at the joint of the other half-screw sleeve, and the plug-in grooves are plugged into the corresponding plug-in posts.

[0013] As a preferred embodiment of this utility model, a hand-tightening ring is fixedly sleeved on the upper outer side of the adjusting sleeve. The hand-tightening ring is made of hard rubber and its outer surface is roughened.

[0014] Compared with the prior art, this utility model provides a flamethrower that can stand upright and prevent tipping, which has the following beneficial effects:

[0015] 1. This upright anti-tipping flame gun, through the setting of a linkage support plate, can be embedded in soft ground or increase the contact area with flat surfaces after unfolding. The multi-point support disperses the center of gravity, ensuring that the flame gun stands stably upright in wet and uneven terrain, thereby playing a role in preventing tipping.

[0016] 2. This upright, anti-tipping flamethrower, through the setting of a split-structure external screw-in assembly, allows the external support parts of the flamethrower to be disassembled and maintained, and can be installed on other fuel tanks of the same size, which can reduce replacement costs and is highly flexible.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model discloses a vertical anti-tipping flame gun, including a fuel tank 1. An ignition and combustion component 2 is provided at the upper end of the fuel tank 1. An external screw connection component 3 is sleeved on the lower side of the outer end of the fuel tank 1. An adjusting sleeve 4 is threadedly sleeved on the outer end of the external screw connection component 3. The lower end of the external screw connection component 3 is flush with the bottom of the fuel tank 1 and is clamped with a retaining sleeve 7. Multiple connecting rods 10 are fixedly connected at intervals around the retaining sleeve 7. The outer ends of the multiple connecting rods 10 are rotatably connected to a support plate 8.

[0024] The fuel tank 1 and the ignition and combustion assembly 2 both adopt the structure commonly used in existing flame guns, which will not be described in detail here.

[0025] A rotating ring 6 is rotatably sleeved on the lower outer side of the adjusting sleeve 4. Multiple connecting rods 9 are rotatably connected at intervals to the outer end of the rotating ring 6. The lower end of the connecting rods 9 is rotatably connected to the support plate 8.

[0026] Specifically, connecting rod 2 10 is fixed between the sleeve 7 and the support plate 8, serving as the fulcrum for the rotation of the support plate 8 and limiting its unfolding angle. The upper end of connecting rod 1 9 is connected to the rotating ring 6, and the lower end is hinged to the outside of the support plate 8. When the adjusting sleeve 4 rotates, it drives the rotating ring 6 to move up and down, which in turn pushes the support plate 8 to unfold outward or retract inward around the fulcrum of connecting rod 2 10 via connecting rod 1 9. When unfolded, the support plate 8 is arranged in a ring shape, contacting the ground to form a stable support surface; when retracted, it fits against the fuel tank 1, reducing the space occupied.

[0027] In addition, the unfolding angle of the multiple support plates 8 can be adjusted. After further unfolding, the edges of the support plates 8 can be embedded in soft ground, thus adapting to uneven placement surfaces. This flexibility makes them more suitable for outdoor scenarios.

[0028] It should be noted that the threads of the adjusting sleeve 4 require a large torque to rotate, to avoid accidental contact that could cause the support plate 8 to unfold or retract unexpectedly.

[0029] In this embodiment, connecting rod 9 is rotatably connected to the middle of the outer side of the upper end face of the support plate 8, and connecting rod 10 is rotatably connected to the middle of the inner side of the support plate 8.

[0030] Specifically, the positions of connecting rod 1 (9) and connecting rod 2 (10) are both located on the center line of support plate 8, which facilitates smooth unfolding or retraction.

[0031] In this embodiment, multiple support pieces 8 are all fan-shaped with beveled edges, arranged in a ring around the sleeve 7, and their lower surfaces are flush with the lower surface of the sleeve 7 when horizontally unfolded.

[0032] Specifically, after the support plate 8 is unfolded, the flamethrower can be placed vertically on the ground. The multi-point support resists lateral forces such as wind or operational vibrations, preventing it from tipping over and causing safety hazards.

[0033] In this embodiment, at least two arc-shaped grooves are spaced apart on the lower end face of the connecting rod 9, and a friction pad 11 is fixedly embedded inside the groove.

[0034] Specifically, the friction pad 11 is embedded in the arc-shaped groove at the bottom of the connecting rod 9. When the support plate 8 is unfolded, it contacts the ground and prevents slippage by increasing friction.

[0035] In this embodiment, the external threaded assembly 3 includes two threaded semi-threaded sleeves 31 on their outer surfaces. The two semi-threaded sleeves 31 are joined together to form a cylindrical shape that covers the outside of the fuel tank 1. An upper collar 32 is fixedly connected to the upper end of the semi-threaded sleeve 31. The outer ends of the two upper collars 32 are provided with grooves. The two grooves are interconnected and fitted with clamps 33. The opening of the clamps 33 is connected by bolts.

[0036] Specifically, the external threaded assembly 3 is composed of two half-threaded sleeves 31, and the clamp 33 further locks and fixes it to prevent the assembly from loosening due to vibration.

[0037] In addition, the modular structure facilitates disassembly and maintenance, and can be installed on other fuel tanks of the same size, which can reduce replacement costs.

[0038] Specifically, during disassembly, first rotate the adjusting sleeve 4 to the lower position, then pull down the retaining sleeve 7 that is engaged with the outer screw assembly 3. Then continue to rotate the adjusting sleeve 4 downwards until it is completely disengaged from the outer screw assembly 3. Finally, loosen the clamp 33 to separate the two half-screw sleeves 31 and complete the disassembly.

[0039] In this embodiment, two plug-in posts 34 are fixedly connected to the lower end of the joint of one half of the threaded sleeve 31, and two plug-in grooves 35 are opened at the joint of the other half of the threaded sleeve 31, and the plug-in grooves 35 are plugged into the plug-in posts 34 respectively.

[0040] Specifically, rapid assembly is achieved through precise alignment of the insertion post 34 and the insertion slot 35.

[0041] In this embodiment, a hand-tightening ring 5 is fixedly sleeved on the upper outer side of the adjusting sleeve 4. The hand-tightening ring 5 is made of hard rubber and its outer surface is roughened.

[0042] Specifically, the surface of the hard rubber hand-tightening ring 5 on the outside of the adjusting sleeve 4 has a rough texture to provide grip friction and facilitate one-handed rotation operation.

[0043] The working principle and usage process of this utility model are as follows: In use, firstly, rotate the hand-tightening ring 5 counterclockwise, causing the adjusting sleeve 4 to drive the rotating ring 6 downward. This, through the connecting rod 9, pulls the support plate 8 to unfold to a horizontal state. After unfolding, the support plate 8 is arranged in a ring shape, contacting the ground to form a stable support surface, increasing the support area and preventing tipping. When preventing tipping on uneven ground, the unfolding angle of the support plate 8 can be further adjusted so that the support plate 8 forms a polygonal supporting structure, stabilizing the fuel tank 1. The beveled edge structure of the support plate 8 also facilitates insertion into the ground, further improving stability.

[0044] After use, the hand-tightening ring 5 can be rotated clockwise to allow the support plate 8 to close and fit the fuel tank 1, thereby reducing space occupation and making it easier to store.
