Detachable fuel gas flame gun

Abstract

The utility model relates to the technical field of flame guns, in particular to a detachable gas flame gun which comprises a flame projector body, and a containing cavity is formed in the flame projector body. The flame projector further comprises an air inlet knob which is arranged on the flame projector body, and the air inlet amount is adjusted through the air inlet knob. According to the detachable fuel gas flame gun, through cooperation of the arranged limiting block and the abutting mechanism, when the abutting mechanism extrudes the limiting block, the limiting block ascends to limit the gas inlet rotary knob, and therefore the gas inlet rotary knob cannot be adjusted when the abutting mechanism is not pushed; therefore, the danger caused by gas leakage or flame increase due to the fact that a worker easily touches the adjusting valve by mistake when adjusting a workpiece is avoided, and the worker does not need to push the push plate all the time when adjusting the gas inlet knob, so that the adjustment of the gas inlet knob can be freely switched between free adjustment and restrictive adjustment.

Description

Technical Field

[0001] The utility model relates to the technical field of blowtorches, in particular to a detachable gas blowtorch. Background Technique

[0002] Gas blowtorches are widely used in many fields, such as for picnics, barbecues, and are often used even for welding jewelry and car repairs. In order to facilitate transportation and carrying, the existing gas blowtorches usually adopt a split design of the gun body and the handle, and are connected during use.

[0003] However, when the staff uses the blowtorch for workpiece processing, they need to frequently adjust the position and angle of the workpiece. For some large-sized workpieces, they need to temporarily put down the blowtorch to adjust the workpiece. In order to facilitate the next use of the blowtorch, the staff generally chooses to turn down or extinguish the flame of the blowtorch and place it aside. In this way, when the staff adjusts the workpiece, it is easy to accidentally touch the regulating valve, resulting in gas leakage or an increase in the flame, which is very dangerous. Therefore, we propose a detachable gas blowtorch. Content of the Utility Model

[0004] One technical problem to be solved by this application is: how to restrict the adjustment of the intake knob.

[0005] To solve the above technical problem, the embodiment of this application provides a detachable gas blowtorch, which includes a blowtorch main body, and a receiving cavity is opened in the blowtorch main body;

[0006] It further includes:

[0007] An intake knob, which is arranged on the blowtorch main body, and the intake amount is adjusted through the intake knob;

[0008] A limiting block, which is slidably arranged in the receiving cavity;

[0009] A pressing mechanism, which is slidably arranged in the receiving cavity. By pressing the limiting block through the pressing mechanism, the limiting block rises to restrict the intake knob.

[0010] In some embodiments, the pressing mechanism includes a movable block, which is slidably arranged in the receiving cavity. One side of the movable block is provided with an inclined surface. A fixing plate is arranged in the receiving cavity, and the fixing plate is arranged on both sides of the movable block. A U-shaped groove is opened on the fixing plate. A groove is opened on the movable block, and a bracket is arranged in the groove. A first spring is arranged between the bracket and the movable block. Embedding rods are arranged on both sides of the bracket, and the embedding rods are embedded in the U-shaped groove. The bracket is connected to the fixing plate through the embedding rods, and a pushing plate is arranged on the upper surface of the bracket.

[0011] In some embodiments, one side of the limiting block is provided with an inclined surface, which is parallel to the inclined surface on one side of the movable block. A sliding rod is arranged in the accommodating cavity, and the limiting block is slidably arranged on the sliding rod. The limiting block is slidably connected to the flamethrower body through the sliding rod. A second spring is arranged between the sliding rod and the accommodating cavity, and the limiting block penetrates through the upper surface of the flamethrower body.

[0012] In some embodiments, the intake knob is arranged on the intake valve of the flamethrower body, and a gear is arranged on the lower surface of the intake knob. The limiting block can be embedded between the teeth of the gear.

Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1

[0029] Please refer to Figure 1-7 , the present utility model provides a technical solution: a detachable gas flamethrower, including a flamethrower main body 1, an accommodation cavity 11 is opened in the flamethrower main body 1; further including: an air intake knob 4 provided on the flamethrower main body 1 for adjusting the air intake amount, and a limiting block 6 slidably disposed in the accommodation cavity 11, and a pushing mechanism 5 slidably disposed in the accommodation cavity 11, by the pushing mechanism 5 squeezing the limiting block 6, the limiting block 6 is lifted to limit the air intake knob 4.

[0030] The actuating mechanism 5 includes a movable block 51 which is slidably arranged in the accommodating cavity 11. One side of the movable block 51 is provided with an inclined surface. A fixed plate 53 is arranged in the accommodating cavity 11. The fixed plate 53 is arranged on both sides of the movable block 51. A U-shaped groove 531 is formed in the fixed plate 53. A groove is formed in the movable block 51, and a bracket 52 is arranged in the groove. A first spring 521 is arranged between the bracket 52 and the movable block 51. Embedding rods 522 are arranged on both sides of the bracket 52, and the embedding rods 522 are embedded in the U-shaped groove 531. The bracket 52 is connected to the fixed plate 53 through the embedding rods 522. A push plate 7 is arranged on the upper surface of the bracket 52. By means of the arranged U-shaped groove 531, when the bracket 52 is at both ends of the U-shaped groove 531, its movement is restricted, so as to ensure that the limiting block 6 is not squeezed by the bracket 52. And by arranging the first spring 521, the position of the bracket 52 can be automatically reset, so that the bracket 52 can move upward autonomously and can smoothly enter both ends of the U-shaped groove 531.

[0031] One side of the limiting block 6 is provided with an inclined surface which is parallel to the inclined surface on one side of the movable block 51. A sliding rod 61 is arranged in the accommodating cavity 11. The limiting block 6 is slidably arranged on the sliding rod 61. The limiting block 6 is slidably connected to the flame sprayer main body 1 through the sliding rod 61. A second spring 62 is arranged between the sliding rod 61 and the accommodating cavity 11. The limiting block 6 penetrates through the upper surface of the flame sprayer main body 1. By arranging an inclined surface on one side, when the limiting block 6 is squeezed by the movable block 51, its position is changed, and thus it no longer restricts the intake air knob 4.

[0032] The intake air knob 4 is arranged on the intake valve of the flame sprayer main body 1. A gear 41 is arranged on the lower surface of the intake air knob 4. The limiting block 6 can be embedded between the teeth of the gear 41. When the limiting block 6 is engaged between the teeth of the gear 41, the rotation of the intake air knob 4 can be restricted, and the dense teeth on the gear 41 enable the intake air knob 4 to be fixed at any angle.

[0033] A flame spray pipe 2 is arranged on the flame sprayer main body 1. A fixing bolt 3 is arranged between the flame sprayer main body 1 and the flame spray pipe 2. The flame sprayer main body 1 and the flame spray pipe 2 are connected through the fixing bolt 3. An avoidance groove 12 is formed in the flame sprayer main body 1. The push plate 7 penetrates through the surface of the flame sprayer main body 1 through the avoidance groove 12.

[0034] In use, the flame spraying tube 2 is connected to the flame sprayer main body 1 through the fixing bolt 3, and then the flame sprayer main body 1 is connected to the gas cylinder. By pressing down the push plate 7, the bracket 52 sinks, so that the bracket 52 can move along the U-shaped groove 531. When the push plate 7 is pushed forward, the movable block 51 presses the inclined surface of the limiting block 6, thereby driving the limiting block 6 to descend, so that the limiting block 6 withdraws from between the teeth of the gear 41, enabling the intake knob 4 to rotate normally. Since the U-shaped groove 531 is of a U-shaped structure, after the push plate 7 is pushed to the limit position and then released, the bracket 52 is restricted by the U-shaped groove 531 through the embedding rod 522, making the limiting block 6 unable to rise. After use, the push plate 7 is reset, making the intake knob 4 unable to rotate. In this way, when the operator places the blowtorch, the push plate 7 is placed in the initial position, making the intake knob 4 unable to rotate, thereby avoiding situations such as gas leakage caused by the operator accidentally touching the intake valve and improving the safety of the blowtorch. When the blowtorch is freely used, the push plate 7 is pushed up, causing the limiting block 6 to descend, and the intake amount is adjusted by rotating the intake knob 4.

[0035] Embodiment 2

[0036] Please refer to Figure 1-8 , the present utility model provides a technical solution: a detachable gas blowtorch, and Embodiment 2 is an optimization based on Embodiment 1;

[0037] Both sides of the push plate 7 are arranged in an upwardly tilted structure.

[0038] By arranging both sides of the push plate 7 in an upwardly tilted structure, during the process of pushing or pulling back the push plate 7, the thumb has a supporting part through the upwardly tilted structures on both sides of the push plate 7, thus facilitating the movement of the push plate 7.
