Description

Technical Field

[0001] This utility model relates to the technical field of natural gas guns with adjustable air caps, and more particularly to a natural gas gun with an adjustable air cap. Background Technology

[0002] In natural gas-related work scenarios, natural gas nozzles are commonly used tools, and their performance has a significant impact on work efficiency and quality. Whether in metal processing and pipeline welding in industrial production, or in small-scale gas construction projects in the construction field, the stable and efficient operation of natural gas nozzles is crucial to ensuring the smooth progress of the work. However, traditional natural gas nozzles have revealed a series of thorny problems in actual use.

[0003] From a connection perspective, traditional air guns often suffer from significant instability in their connection structures. Currently, common connection methods for traditional air guns include simple socket connections and ordinary threaded connections. In simple socket connections, the connection between the connector and the air hose relies solely on the pipe diameter, lacking effective fixing and sealing measures such as sealing rings or fastening clamps. While ordinary threaded connections improve the tightness of the connection to some extent, their effectiveness remains unsatisfactory in complex working environments. In actual operations, various vibration sources are unavoidable at construction sites, such as the operation of large machinery and collisions during material handling. Under the influence of these vibrations and collisions, air guns with traditional connection structures are highly susceptible to natural gas leakage. Under high-pressure impacts, the connections in traditional structures are more prone to loosening, further exacerbating the risk of natural gas leakage. Therefore, a natural gas air gun with an adjustable air cap is proposed to address these issues. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] Example 1

[0027] Traditional air guns commonly use simple socket connections and ordinary threaded connections. The connection between the connector and the air hose relies solely on the pipe diameter, lacking effective fixing and sealing measures such as sealing rings and fastening clamps. While ordinary threaded connections improve the tightness of the connection to some extent, their effectiveness remains unsatisfactory in complex working environments. In actual operations, various vibration sources are unavoidable at construction sites, such as the operation of large machinery and collisions during material handling. Under the influence of these vibrations and collisions, air guns with traditional connection structures are highly susceptible to natural gas leakage. Under high-pressure impacts, the connections in traditional structures are more prone to loosening, further exacerbating the risk of natural gas leakage. This embodiment provides a natural gas air gun with an adjustable air cap. Please refer to... Figures 1-6 An embodiment provides a natural gas gun with an adjustable wind cap, including a handle 1. The handle 1 is provided with a connecting mechanism 2. The connecting mechanism 2 includes an opening and closing component 21 located in the middle section of the handle 1, a connecting component 22 located in the left section of the handle 1, and an adjusting component 23 located in the right section of the handle 1. The connecting component 22 includes a gas pipe 221 fixedly connected to the inner wall of the handle 1 and connected to it. A connecting connector 222 is connected to the left end of the gas pipe 221. A mounting shell 223 is fixedly connected to the left end of the handle 1. A rotating block 224 is rotatably connected to the inner wall of the mounting shell 223. A limit ring cover 225 is rotatably connected to the inner wall of the annular groove opened in the inner wall of the rotating block 224. A limit spring 226 is fixedly connected to the inner wall of the rotating block 224. A limit strip 227 is fixedly connected to the inner side of the limit spring 226.

[0028] In this embodiment, the grip 1 serves as the handheld part of the air gun, and the air pipe 221 connected to its inner wall is a channel for natural gas transmission; the connecting joint 222 connected to the left end of the air pipe 221 is used to connect to an external natural gas supply source; the connecting joint 222 is located inside the cavity formed by the rotating block 224 and the limiting ring cover 225, which increases the stability and sealing of the connection; the mounting shell 223 is fixedly connected to the left end of the grip 1, providing installation space for components such as the rotating block 224; the rotating block 224 rotates on the inner wall of the mounting shell 223, and the inner wall of the annular groove opened on its inner wall rotates. The connecting limiting ring cover 225 can limit the rotation range of the rotating block 224 and prevent the connecting joint 222 from rotating excessively, causing the air tube 221 to twist or be damaged. The limiting spring 226 is fixedly connected to the inner wall of the rotating block 224, and the limiting strip 227 is fixedly connected to the inner side of the limiting strip 227, which is slidably connected to the inner wall of the limiting groove opened in the limiting ring cover 225. When the rotating block 224 rotates, the limiting spring 226 slides in the limiting groove of the limiting ring cover 225 through the limiting strip 227, which plays a role in buffering and resetting, further ensuring the stability of the connection and preventing the connection from loosening due to external impact.

[0029] Furthermore, the connecting joint 222 is disposed inside the cavity formed by the rotating block 224 and the limiting ring cover 225; the limiting strip 227 is slidably connected to the inner wall of the limiting groove opened in the limiting ring cover 225.

[0030] Furthermore, the connecting joint 222 is located inside the cavity formed by the rotating block 224 and the limiting ring cover 225. This design increases the stability and sealing of the connection. The mounting shell 223 is fixedly connected to the left end of the handle 1, providing installation space for components such as the rotating block 224. The rotating block 224 rotates on the inner wall of the mounting shell 223. The limiting ring cover 225, which is rotatably connected to the inner wall of the annular groove on its inner wall, can limit the rotation range of the rotating block 224 and prevent the connecting joint 222 from rotating excessively, which could cause the air tube 221 to twist or be damaged.

[0031] Example 2

[0032] Based on embodiment 1, the opening and closing assembly 21 includes a mounting ring 212 fixedly installed on the right end of the handle 1, a grip ring 211 fixedly connected to the outer wall of the handle 1, an opening and closing valve 213 connected to the bottom of the mounting ring 212, a pressure plate 216 fixedly connected to the bottom of the opening and closing valve 213, an arc-shaped rod 214 fixedly connected to the bottom of the handle 1, and a connecting spring 215 sleeved on the upper outer wall of the arc-shaped rod 214; the adjusting assembly 23 includes a connecting pipe 231, a wind cap 232 connected to the outer end of the connecting pipe 231, a fixing ring 233 fixedly connected to the outer wall of the connecting pipe 231, a rotating ring 234 threadedly connected to the outer wall of the wind cap 232, a connecting rod 235 rotatably connected to the outer wall of the rotating ring 234, a hinge block 236 hinged to the outer end of the connecting rod 235, and a hinged wind cap opening 237 fixedly connected to the inner side of the hinge block 236.

[0033] In this embodiment, the mounting ring 212 fixedly installed on the right end of the handle 1 provides a mounting base for the opening and closing assembly; the grip ring 211 fixedly connected to the outer wall of the handle 1 facilitates the user's grip on the air gun; the opening and closing valve 213 connected to the bottom of the mounting ring 212 is a key component for controlling the on / off and flow of natural gas; the pressure plate 216 fixedly connected to the bottom of the opening and closing valve 213 opens the valve 213 when the user presses the pressure plate 216, and natural gas flows out from the gas pipe 221 through the opening and closing valve 213; the pressure plate A limiting port is provided at 216. An arc-shaped rod 214, fixedly connected to the bottom of the handle 1, is located inside the limiting port. A connecting spring 215, sleeved on the upper outer wall of the arc-shaped rod 214, abuts against the top of the pressure plate 216. When the user releases the pressure plate 216, the elastic force of the connecting spring 215 causes the pressure plate 216 to return to its original position, thereby closing the opening and closing valve 213 and stopping the flow of natural gas. By controlling the pressure applied to the pressure plate 216, the opening degree of the opening and closing valve 213 can be adjusted, thereby precisely controlling the flow of natural gas. The flow rate and injection force are controlled by the following: One end of the connecting pipe 231 is connected to the gas pipe 221, and the other end is connected to the ventilation cap 232, which is the channel for natural gas to flow from the gas pipe 221 to the ventilation cap 232; the fixing ring 233 fixedly connected to the outer wall of the connecting pipe 231 serves to strengthen the connection and fix it; the rotating ring 234 is threadedly connected to the outer wall of the ventilation cap 232. When the rotating ring 234 is rotated, it will move along the outer wall of the ventilation cap 232 due to the threaded connection; the connecting rod 235 is rotatably connected to the outer wall of the rotating ring 234. As the rotating ring 234 moves, the connecting rod 235 will swing; the hinge block 236 hinged to the outer end of the connecting rod 235 moves under the action of the connecting rod 235; the hinged ventilation cap opening 237 fixedly connected to the inner side of the hinge block 236 can change the angle between the hinged ventilation cap opening 237 and the main body of the ventilation cap 232 through the action of the connecting rod 235 and the hinge block 236, thereby adjusting the airflow range and intensity of the natural gas injection to adapt to different operating scenarios.

[0034] Furthermore, the pressure plate 216 has a limiting port, the arc-shaped rod 214 is set in the inner cavity of the limiting port, and the bottom of the connecting spring 215 abuts against the top of the pressure plate 216; the other end of the connecting pipe 231 is connected to an air pipe 221.

[0035] Furthermore, by controlling the pressure of the pressing plate 216, the opening degree of the valve 213 can be adjusted, thereby precisely controlling the flow rate and injection force of natural gas; one end of the connecting pipe 231 is connected to the gas pipe 221, and the other end is connected to the ventilation cap 232, which is the channel for natural gas to flow from the gas pipe 221 to the ventilation cap 232; the fixing ring 233 fixedly connected to the outer wall of the connecting pipe 231 plays a role in strengthening the connection and fixing.

[0036] Working principle: The grip 1 serves as the handheld part of the air gun, and the air pipe 221 connected to its inner wall is the channel for natural gas transmission; the connecting joint 222 connected to the left end of the air pipe 221 is used to connect to an external natural gas supply source; the connecting joint 222 is located inside the cavity formed by the rotating block 224 and the limiting ring cover 225, which increases the stability and sealing of the connection; the mounting shell 223 is fixedly connected to the left end of the grip 1, providing installation space for components such as the rotating block 224; the rotating block 224 rotates on the inner wall of the mounting shell 223, and the annular groove opened on its inner wall rotates and connects to the inner wall. The limiting ring cover 225 can limit the rotation range of the rotating block 224 and prevent the connecting joint 222 from rotating excessively, which could cause the air tube 221 to twist or be damaged. The limiting spring 226 is fixedly connected to the inner wall of the rotating block 224, and the limiting strip 227 is fixedly connected to the inner side of the limiting strip 227, which is slidably connected to the inner wall of the limiting groove opened in the limiting ring cover 225. When the rotating block 224 rotates, the limiting spring 226 slides in the limiting groove of the limiting ring cover 225 through the limiting strip 227, which plays a role in buffering and resetting, further ensuring the stability of the connection and preventing the connection from loosening due to external impact.

[0037] The mounting ring 212 fixedly installed on the right end of the handle 1 provides a mounting base for the opening and closing assembly; the grip ring 211 fixedly connected to the outer wall of the handle 1 facilitates the user's grip on the air gun; the opening and closing valve 213 connected to the bottom of the mounting ring 212 is a key component for controlling the on / off and flow of natural gas; the pressure plate 216 fixedly connected to the bottom of the opening and closing valve 213 opens when the user presses the pressure plate 216, allowing natural gas to flow out from the gas pipe 221 through the opening and closing valve 213; the pressure plate 216 has a limited opening. The handle 1 has an arc-shaped rod 214 fixedly connected to the bottom and positioned inside the limiting port. The upper part of the arc-shaped rod 214 is sleeved on the outer wall, and the bottom of the connecting spring 215 abuts against the top of the pressure plate 216. When the user releases the pressure plate 216, the elastic force of the connecting spring 215 causes the pressure plate 216 to return to its original position, thereby closing the opening and closing valve 213 and stopping the flow of natural gas. By controlling the force of pressing the pressure plate 216, the opening degree of the opening and closing valve 213 can be adjusted, thereby precisely controlling the flow rate and injection force of natural gas.

[0038] One end of the connecting pipe 231 is connected to the gas pipe 221, and the other end is connected to the ventilation cap 232, serving as the channel for natural gas to flow from the gas pipe 221 to the ventilation cap 232. The fixing ring 233, fixedly connected to the outer wall of the connecting pipe 231, serves to strengthen the connection and fix the pipe. The rotating ring 234, threadedly connected to the outer wall of the ventilation cap 232, moves along the outer wall of the ventilation cap 232 when rotated due to the threaded connection. The connecting rod 235, rotatably connected to the outer wall of the rotating ring 234, swings as the rotating ring 234 moves. The hinge block 236, hinged to the outer end of the connecting rod 235, moves under the action of the connecting rod 235. The hinged ventilation cap opening 237, fixedly connected to the inner side of the hinge block 236, can change the angle between the hinged ventilation cap opening 237 and the main body of the ventilation cap 232 through the action of the connecting rod 235 and the hinge block 236, thereby adjusting the airflow range and intensity of the natural gas injection to adapt to different operational needs.
