Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic nail guns, and particularly relates to a safety structure of a pneumatic gas gun. Background Art

[0002] A pneumatic gas gun is a decoration tool that can quickly drive steel nails into concrete. Due to its large impact force, if misfiring occurs during use, the danger is quite high. To avoid misfiring, a safety device is generally set on the nail gun. In the prior art, the safety device is relatively cumbersome, which not only increases the difficulty of processing and manufacturing but also increases the manufacturing cost. Content of the Utility Model

[0003] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a safety structure of a pneumatic gas gun.

[0004] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0005] A safety structure of a pneumatic gas gun includes a gun head, the gun head is connected with an installation rod, the installation rod is provided with a slide way, a screw hole and a first boss, the installation rod slidably installs a safety frame through the slide way, the safety frame is integrally connected with a trigger plate, the end position of the trigger plate corresponds to a drive switch, the safety frame is integrally provided with a second boss, and a spring is installed between the second boss and the first boss;

[0006] The safety frame is integrally installed with a round hole, a nozzle is installed in the round hole, the nozzle is integrally connected with a cylinder, the cylinder is integrally provided with a limit boss, the cylinder is provided with a chute, the screw hole is threadedly connected with a locking screw, and the end of the locking screw is located in the chute, and the end of the locking screw does not contact the inner bottom of the chute.

[0007] Further limited, blocking parts are provided at both ends of the slide way, and the safety frame is integrally connected with a wing plate located in the slide way. With such a design, the movement of the safety frame is further limited.

[0008] Further limited, rib strips are installed on four sides of the installation rod. With such a design, the overall strength of the installation rod is enhanced. [[ID=3__0]]

[0009] Further limited, the gun head and the installation rod are integrally formed. With such a design, the structural strength is enhanced and it is not easy to fall off and break.

[0010] Further limited, fixing holes are installed at four corner positions of the gun head, and the gun head is thickened at the position where the fixing holes are installed. With such a design, the installation strength is ensured.

[0011] Beneficial Effects of Adopting the Present Utility Model:

[0012] With the structural design of the utility model, under the action of the spring, the safety frame always pushes the gun nozzle downward to the limit position. When the gun nozzle is pushed back by an external force, the safety frame is pushed by the gun nozzle, thereby driving the nail gun to fire. Therefore, the problem of accidental firing is not easy to occur. In addition, the overall structure is simple and clear, which is conducive to production and manufacturing, and has low cost.

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention is a safety structure of a pneumatic gas gun, comprising a gun head 1, the gun head 1 being connected to a mounting rod 2, the mounting rod 2 being provided with a slideway 3, a screw hole 4, and a first boss 5, the mounting rod 2 being slidably mounted with a safety frame 6 via the slideway 3, the safety frame 6 being integrally connected to a trigger plate 7, the end position of the trigger plate 7 corresponding to the drive switch, the safety frame 6 being integrally provided with a second boss 8, and a spring 9 being installed between the second boss 8 and the first boss 5;

[0021] The safety bracket 6 is integrally installed with a round hole 10. A nozzle 11 is installed in the round hole 10. The nozzle 11 is integrally connected with a cylinder 12. The cylinder 12 is integrally provided with a limiting boss 13. A chute 14 is provided on the cylinder 12. A locking screw 15 is threadedly connected to the screw hole 4. The end of the locking screw 15 is located in the chute 14, and the end of the locking screw 15 does not contact the inner bottom of the chute 14.

[0022] In this embodiment, when using the safety structure of a pneumatic gas gun, when the pneumatic gas gun is in a normal state, under the elasticity of the spring 9, the safety bracket 6 moves away from the gun head 1, pushing the nozzle 11 to also move away from the gun head 1. The chute 14 on the cylinder 12 connected to the nozzle 11 is limited by the locking screw 15, so the nozzle 11 cannot be completely disengaged, thus forming a static pull. The movement of the safety bracket 6 causes the trigger plate 7 to also displace, making the pneumatic gas gun unable to start, thereby achieving the purpose of insurance.

[0023] When a force is applied to the front end of the nozzle 11, the nozzle 11 moves towards the gun head 1, compressing the spring 9 and pushing the safety bracket 6 towards the gun head 1, causing the trigger plate 7 to contact the drive switch, thereby achieving the purpose of starting.

[0024] In summary, only when a force is applied to the nozzle 11 can the gas gun start, and the insurance effect is good.

[0025] Preferably, stoppers are provided at both ends of the slideway 3. The safety bracket 6 is integrally connected with a wing plate 16 located in the slideway 3. With such a design, the movement of the safety bracket 6 is further limited. In fact, the limiting structure can also be considered according to specific circumstances.

[0026] Preferably, ribs 17 are installed on all four sides of the mounting rod 2. With such a design, the overall strength of the mounting rod 2 is enhanced. In fact, the number and specification dimensions of the ribs 17 can also be considered according to specific circumstances.

[0027] Preferably, the gun head 1 and the mounting rod 2 are integrally formed. With such a design, the structural strength is enhanced, and it is not easy to fall off or break. In fact, the connection structure between the gun head 1 and the mounting rod 2 can also be considered according to specific circumstances.

[0028] Preferably, fixing holes 18 are installed at the four corners of the gun head 1, and the gun head 1 is thickened at the positions where the fixing holes 18 are installed. With such a design, the installation strength is ensured. In fact, the specification, quantity, and position of the fixing holes 18 can also be considered according to specific circumstances.

[0029] The above embodiments are only illustrative of the principles and effects of the present utility model, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present utility model should still be covered by the claims of the present utility model.
