Description

Gas fire control system

The invention relates to a fire control adjustment structure, in particular to a fire control adjustment structure used on a gas torch.

According to the use of gas firearms in daily life, while the industry is developing and designing a new generation of gas firearms, in addition to the technical improvement of the heating reaction speed and automatic fire-breaking function of the gas torch structure itself, How the structure of the gas firearm can simplify its assembly and adjustment process and improve production efficiency in the production process, and it is also the main design goal of the structure that reduces the labor cost and the production capacity.

Due to the technical solution proposed in this case, there are mainly the steps to establish how to simplify the fire control adjustment structure of the gas torch, and how to make the gas discharge of each gas torch at the factory before the quality control personnel. The uniform adjustment of quantity is more convenient and convenient, and the technical means for research and development of the fire control adjustment structure of the gas firearm is provided. In addition, the structure, action principle and function of other relevant parts of the gas spray gun are The public use of the technology, so it will not be further described, the reader can obtain the relevant technical information related to the structure, operation principle and function of other relevant parts of the gas torch as described above, as disclosed in U.S. Patent No. 6,293,782. .

However, the control structure of the gas firearms of the conventional technology on the market is as shown in Figure 1-1 to Figure 1-4. It can be clearly seen from the continuous action diagrams. The fire control adjustment structure 1 described in the prior art is mainly achieved by locking a rotary setting member 2 of a ring sleeve outside the fire control gear 4 by using a positioning screw 3; that is, when "Fig. 1" -1" When the positioning screw 3 is locked and the tip is pressed against the fire control gear 4, the rotary fire control member 2 can be pulled to drive the fire control gear 4 to control the gas discharge amount, but due to the general gas fire The gun is designed to provide the user with a fixed amplitude limit for the space in which the rotary fire control member 2 can be pulled. Therefore, the prior art fire control adjustment structure 1 is used by the production personnel to connect the gas to the gas torch. After the assembly is completed, whether the fire control gear 4 is locked by the rotary fire control member 2 with the positioning screw 3 when the gas injection gun is turned on and ignited is a proper position of the normal gas discharge amount, and must be passed through the quality control tube before leaving the factory. The personnel will make a unified adjustment for each gas firearm; as mentioned above, the study The fire control adjustment structure 1 of the prior art is required to continuously rotate the set screw 3 with a screw lock tool until it is abutted against the fire control gear 4, so that it has a cumbersome lack of assembly steps. And when the quality control personnel ignite the gas spray gun before leaving the factory, it is determined that the gas discharge is too large or too small, and the screw should be rotated by the screw lock tool to loosen the set screw 3 as shown in Figure 1-2. After the position of the fire trigger 2 and the fire control gear 4 is changed, as shown in "FIG. 1-3", the set screw 3 is tightened and re-fixed as shown in "FIG. 1-4", so that the The positioning screw 3 is loosened and tightened to adjust, which is difficult to adjust and inconvenient.

Please refer to the control structure of the gas firearm of another conventional technology, as shown in Figure 2, Figure 3, Figure 4 and Figure 5-1 to Figure 5-4. For the other conventional technology, the appearance of the gas flame gun, the partial decomposition of the facade, the fire control adjustment structure, the decomposition of the elevation and the plane of the continuous action, as can be clearly seen from the figures, the gas torch 10 The utility model can accommodate the gas and is operated by controlling the release of the gas discharge amount to facilitate the ignition to generate a high temperature, and includes a buckle switch 14 and an exhaust puller 13 controlled by the buckle switch 14 to be actuated up and down. An exhaust pipe 12 that controls the release of gas in the gas torch 10 by the exhaust trigger 13 and a fire control gear 11 disposed on the path of the exhaust pipe 12 for adjusting the gas discharge amount; The fire control adjustment structure 20 is sleeved on the fire control gear 11; wherein the exhaust puller 13 defines a hole 131 for clamping the exhaust pipe 12 when the pressure is pressed When the buckle 14 is pressed against one end of the exhaust puller 13, the exhaust puller 13 can be clamped to the other end of the exhaust pipe 12 upward. Synchronizing the exhaust pipe 12 to achieve the function of discharging the gas; and the fire control adjustment structure 20 includes an auxiliary fire control gear 22 annularly sleeved on the fire control gear 11, and the auxiliary fire control gear 22 is inside the ring The edge has an internal tooth 222 that cooperates with the pitch of the fire control gear 11 and is coupled to each other, and the inner edge of the ring has an external tooth 223. The outer tooth 223 is radially extended to form a plurality of control slots 221 a rotating fire control puller 21 sleeved on the outer teeth 223 of the auxiliary fire control gear 22, the inner edge of the rotary fire control puller 21 is provided with a maximum of six mutual symmetry and can be mutually coupled with the outer teeth 223 The bump 212 is positioned, and the outer edge of the ring of the rotary fire control member 21 is extended with an operating portion 211 for applying an external force to rotate the rotary fire control member 21.
