Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fastening equipment, in particular to a non-electric gas gun. Background Art
[0002] A gas nail gun uses gas combustion as a driving force for fastening operations. Its main structure consists of a magazine, a handle, and a gun body. The combustion cavity is located at the rear end of the gun head, and a gas canister is placed in the handle, connected to the combustion cavity via a switch. A battery pack and a connected blower are located within the gun body. The blower draws ambient air into the combustion chamber to mix with the gas inside. The battery is connected to an ignition device, an ignition switch, and a power switch. The ignition device is controlled by the ignition switch, and the blower is controlled by the power switch. Therefore, throughout the entire process of mixing gas with ambient air and igniting the gas, the battery serves as the power source to control the activation and deactivation of the corresponding components. While battery-powered ignition and blower-powered mixing of air and gas offer the advantages of convenience and reduced reliance on external power sources, they also present certain safety risks, such as short circuits and leakage. Furthermore, the gun is significantly affected by temperature. While it does not require an external power supply, it still requires regular charging.

[0015] The utility model has the following beneficial effects:
[0016] 1. The utility model provides a contact arm on the nail tube, which is connected to the explosion cylinder at one end of the cylinder body. One end of the contact arm is connected to the valve stem, which extends into the explosion cylinder. The end of the valve stem in the explosion cylinder is connected to the cylinder head.

At this time, the trigger is pulled, compressing the spark plug, and igniting the spark plug. In the utility model, no fan or battery is used for either air intake or ignition. Instead, structures such as a contact arm, a valve stem, an explosion cylinder, and a pressure block are adopted.

[0017] 2. Compared to the ignition assembly, or control circuit assembly, installed in existing gas guns, whose input is connected to a battery and whose output is connected to a fan motor assembly, a high-voltage ignition cap, a position switch, and a trigger switch, and which is expensive, the present invention completely eliminates these structures and eliminates the need for a battery or a charger that comes with the gun. Instead, a contact arm is directly provided on the nail tube, which drives the valve stem and cylinder cover to move within the explosion cylinder. This not only triggers the gas nozzle of the gas tank to allow gas to enter the explosion cylinder, but also allows air to pass through the inclined hole, generating vortexes to mix the gas and air. The entire process is achieved without the need for battery power. Compared to existing gas guns, the gas gun disclosed in the utility model greatly saves costs and improves safety.

DETAILED DESCRIPTION
[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.
[0033] refer to Figures 1-10 The utility model discloses a non-electric gas gun, comprising a housing 1, a cylinder 2 disposed within the housing 1, and an ignition mechanism and an air intake mechanism disposed at the bottom of the cylinder 2. Specifically, the ignition mechanism, cylinder, explosion cylinder, and gas tank are all enclosed within the housing. An explosion cylinder 3 is provided at one end of the cylinder 2, communicating therewith, and a nail tube 4 is inserted into the other end. Specifically, one end of the cylinder is inserted into and secured within the explosion cylinder, and the end surface of the cylinder at the end where the cylinder is secured to the explosion cylinder is flush with the inner wall of the explosion cylinder.
[0034] The explosion cylinder 3 is open at one end away from the cylinder body 2, and a contact arm 5 is fixed on the side wall of the nail tube 4. The contact arm is arranged along the axial direction of the cylinder body. There are two contact arms 5, and they are correspondingly arranged on both sides of the cylinder body 2. A valve stem 6 is fixed to the other end of the contact arm 5. One end of the valve stem 6 extends into the explosion cylinder 3 and is fixed with a cylinder cover 7 adapted to the explosion cylinder 3. A piston ring is provided on the circumference of the cylinder cover. A sealing ring 8 is provided on the valve stem 6 and the connecting end with the contact arm 5. The sealing ring 8 is adapted to the through hole 9 of the valve stem 6 passing through the explosion cylinder 3, thereby sealing the explosion cylinder. A retaining ring 10 for limiting the cylinder cover 7 is provided at the open end of the explosion cylinder 3, and a return spring 11 is provided at the center of the cylinder cover 7 toward the open end of the explosion cylinder 3. It should be noted that when the contact arm moves toward the explosion cylinder, it drives the valve stem to move, and in turn pushes the cylinder head toward the open end of the explosion cylinder. During this process, outside air enters the explosion cylinder through the through hole (the gap between the valve stem and the through hole) and mixes with the gas inside the explosion cylinder. The retaining ring is provided to support the cylinder head. When the sealing ring on the valve stem just seals the through hole, the cylinder head and the retaining ring come into contact. At this time, the space inside the explosion cylinder forms an independent space from the outside world, ensuring that there will be no leakage when the gas explodes. The high-pressure gas can only act on the piston disc of the piston rod, thereby performing work to the left. The setting of the reset spring can prevent the cylinder head from colliding with the retaining ring, and at the same time, it can reset the cylinder head.
[0035] Furthermore, the end surface where the explosion cylinder 3 is connected to the cylinder body 2 is provided with a guide plate 48, and the piston disc in the cylinder body rests on the guide plate to position and support it. One end of the valve stem 6 extends into the explosion cylinder 3 through the guide plate 48, and the valve stem 6 is adapted to the guide plate 48. An air port 50 is provided on the guide plate 48 near the position of the valve stem 6, and an inclined groove 49 facing the air port 50 and communicating with the air port 50 is provided on the side wall of the through hole 9. It should be noted that there is no gap between the valve stem and the guide plate, so that the outside air enters the explosion cylinder through the air inlet formed by the through hole, the inclined groove and the air port in sequence. At the same time, due to the setting of the inclined groove and the air port, a sloped hole is formed, which causes the air entering the explosion cylinder to generate a vortex, thereby stirring and mixing the gas entering the explosion cylinder. Since there are two contact arms, there are also two inclined holes. In order to make the air entering the explosion cylinder form a spiral, the inclined grooves in the through hole and the air outlets on the guide plate are arranged symmetrically with respect to the center. Furthermore, an exhaust hole 12 is provided on the side wall of the cylinder body 2. The exhaust hole is provided on the cylinder body near the nail tube. A valve plate 13 is provided above the exhaust hole 12 outside the cylinder body 2. The valve plate is not fixed to the exhaust hole, but directly covers the exhaust hole. One end of the valve plate 13 is fixed by an arc plate 14, that is, one end of the arc plate presses the valve plate. A flame extinguishing block 15 is provided between the arc plate 14 and the cylinder body 2. The area formed by the arc plate 14 and the flame extinguishing block 15 corresponds to the exhaust hole 12. It should be noted that the cavity between the arc plate and the cylinder body constitutes an exhaust channel connected to the exhaust hole, and the flame extinguishing block and the arc plate are fixed on both sides of the exhaust hole. Above the exhaust hole is a cavity supported by the arc plate and the flame extinguishing block. The high-temperature and high-pressure gas in the cylinder body is discharged by lifting the valve plate to prevent the valve plate from being deformed too much and unable to recover. The flame extinguishing block is a block pressed into a certain density by fine steel wire. The high-temperature and high-pressure gas carries a flame when discharged, and the flame is extinguished after passing through the flame extinguishing block. The channel supported by the arc plate and the flame extinguishing block is connected to the outer shell with an outlet, so that the high-temperature and high-pressure gas is discharged to the outside after passing through the flame extinguishing block. Among them, one end of the arc plate fixing the valve plate is fixed by a clamp 23, that is, the clamp is fixed on the circumference of the cylinder body, and one end of the arc plate is fixed to the cylinder body by the clamp. The number of exhaust holes and arc plates is set according to needs.
[0036] Furthermore, the air intake mechanism includes an air intake seat 16 disposed at the bottom of the cylinder body 2. A first air intake pipe 17 is embedded in the air intake seat 16. A second air intake pipe 18 is provided on the end surface where the explosion cylinder 3 and the cylinder body 2 are connected. The first and second air intake pipes are respectively fixed to the air intake seat and the explosion cylinder. The first and second air intake pipes 17 and 18 are connected by a silicone tube 19. A gas tank 20 is provided below the air intake seat 16. The gas nozzle of the gas tank 20 extends into the first air intake pipe 17. A sealing gasket is provided between the gas nozzle and the first air intake pipe. A gas pressure assembly is provided on the cylinder body 2. When the nail tube 4 moves, the gas pressure assembly drives the gas pressure assembly to press the gas tank 20, compressing the gas nozzle on the gas tank 20, and gas enters the explosion cylinder through the air intake pipe. The gas tank is arranged in the outer shell, forming the handle of the gas gun.
[0037] Furthermore, the air compression assembly includes a V-shaped pressure block 21, with its ends positioned on either side of the cylinder body 2 and rotatably connected to a support block 22. The support block 22 is secured to a clamping hoop 23 positioned outside the cylinder body 2, which is positioned transversely. A first spring 24 is positioned between the clamping hoop 23 and the pressure block 21, ensuring that the pressure block returns to its original position after rotation. Pushing tabs 25 are positioned at each end of the pressure block 21, facing the nail tube 4. The pushing tabs are angled with the ends of the pressure block, such as approximately 90°. A pin 26 is inserted through the pusher tabs 25. The bottom of the contact arm 5 is provided with a slideway 27 with a sloped surface on one side. The slideway can be understood as a notch with a sloped surface. The pin 26 is positioned within the slideway 27. The slope of the slideway is positioned toward the nail tube. When the contact arm 5 moves toward the explosion cylinder 3, the slope of the slideway pushes the pin on the pusher tab downward, causing the pressure block to rotate toward the gas cylinder, thereby compressing the gas nozzle of the gas cylinder.
[0038] Furthermore, a trigger 28 is provided beside the gas tank 20 and at the bottom of the cylinder body 2. Specifically, the trigger is mounted on a housing outside the gas tank. A second spring 29 is mounted on top of the trigger 28, allowing it to reset under the action of the spring when the trigger is pulled. A trigger block 30 is mounted on top of the trigger 28. The ignition mechanism includes a sparker 31 disposed between the trigger block 30 and the clamp 23. A spark plug 32 is inserted into the end surface where the explosion cylinder 3 connects to the cylinder body 2. The spark plug 32 is connected to the sparker 31 via an electrical wire. It should be noted that preferably, two sparkers and two spark plugs are provided. The sparkers are arranged horizontally, one on each side of the pressure block. One end of the sparker can be fixed to the clamp or directly clipped into a groove in the clamp; the other end is directly fixed to the trigger block. When the trigger is pulled, the sparker is compressed, generating an electric current, causing the spark plug to produce an electric spark, thereby igniting the gas.
[0039] Furthermore, a first safety mechanism is provided above the trigger 28. When the contact arm is not in position, the first safety mechanism prevents accidental triggering and ignition. Specifically, the first safety mechanism includes a safety plate 33. One end of the safety plate 33 is rotatably connected via a rotating shaft, and the hinged end is the end closest to the nail tube. The other end passes through a "convex" limiting hole 34 provided on the trigger block 30. Upwardly bent wings 35 are provided on both sides of the safety plate 33. The bottom surface of the contact arm 5 is provided with a strip-shaped notch 36, and the end of the wing plate extends into the strip-shaped notch. The strip-shaped notch is connected to the slide, and the two form a stepped shape. It should be noted that in the initial state, the end of the wing plate extending into the strip-shaped notch is located close to the slide. When the contact arm moves, the end surface of the notch contacts the wing plate, thereby driving the safety plate to rotate downward. At this time, pulling the trigger realizes the ignition operation. Among them, the limiting hole is set through the trigger block. In the initial state, the safety plate is located in the groove above the limiting hole; when the contact arm moves, the safety plate is located in the groove below the limiting hole, which releases the restriction on the trigger.
[0040] Furthermore, a piston rod 37 is coaxially disposed within the cylinder body 2. A piston disc 38 is disposed on the end of the piston rod 37 facing the explosion cylinder 3. The piston disc 38 is adapted to fit within the cylinder body 2 and is circumferentially provided with piston rings. A buffer block 39 is provided on the end of the cylinder body 2 corresponding to the piston disc 38 to mitigate impacts caused by the piston disc. The deflector plate 48 has an inner diameter smaller than the inner diameter of the cylinder body 2. An annular groove adapted to fit the deflector plate is provided at the edge of the piston disc facing the explosion cylinder. In the initial state, the annular groove engages the deflector plate, preventing the piston disc from extending into the explosion cylinder and providing support for the piston disc. Furthermore, a nail tube holder 40 is disposed at one end of the cylinder body 2. One end of the nail tube 4 is inserted into the holder 40. A second safety mechanism is provided at the top of the holder 40, and a nail magazine 41 is provided at the bottom of the holder 40. This second safety mechanism is designed to restrain the nail tube, preventing it from moving into the holder when not in use.
[0041] Specifically, the second safety mechanism includes a safety plate 42, one end of which is rotatably connected to the nail tube holder 40, and the other end is provided with a protrusion that is inserted into the nail tube holder 40 and abuts against the tube opening of the nail tube 4 extending into the nail tube holder 40. A steel ball 43 is embedded in the nail tube holder 40, and a second magnet 44 is provided on the safety plate 42 at a position corresponding to the steel ball 43. The end of the safety plate 42 near its hinge is connected to the nail tube holder 40 via a third spring 45. It should be noted that the hinged end of the safety plate is provided near the cylinder body, and the second magnet is provided near the hinged end of the safety plate. The provision of the third spring enables the safety plate to automatically reset after the gas gun completes a shot.
[0042] Furthermore, openings are provided on the outer shell 1 at the open end of the explosion cylinder 3 and near the through hole 9 to facilitate the entry of outside air and the discharge of exhaust gas; a guide tube 46 is provided at the center of the cylinder head 7, and a first magnet 47 is provided in the guide tube 46 to attract the cylinder head and the end of the piston disc or the piston rod, and the return spring 11 is sleeved on the guide tube 46, and the other end is connected to the outer shell 1.
[0043] Figures 1-4 This is the initial state of the gas gun of the utility model, that is, the unused state (the shell is removed). Figure 5-Figure 9 This is a diagram of the gas gun of the present invention in use (including the outer shell).
[0044] by Figures 1-4 This is the initial state. During use, the compressed nail tube 4 moves rightward, driving the contact arm 5 to also move rightward. The contact arm 5 in turn drives the valve stem 6, which in turn drives the cylinder head 7 to move rightward within the explosion cylinder 3, gradually forming a cavity. External air enters the cavity through the gap between the valve stem 6 and the explosion cylinder 3. Simultaneously, during the initial movement of the contact arm 5, it causes the pressure block 21 to rotate, pushing the gas cylinder to the right. The gas nozzle of the compressed gas cylinder then fills the space formed by the explosion cylinder 3 and the cylinder head 7 with gas. The gas is then introduced before the cylinder head 7 reaches approximately one-third of its travel within the explosion cylinder 3. It should be noted that the amount of gas introduced into the explosion cylinder is fixed, specifically determined by the structure of the gas nozzle. To change the amount of gas introduced, simply replace the gas nozzle on the gas cylinder. Varying the amount of gas introduced allows for gas guns of varying power.
[0045] At this point, the nail tube 4 continues to press, and the cylinder cover 7 continues to move rightward until it approaches the right edge of the endpoint. During this process, external air continues to enter through the gap between the valve stem 6 and the explosion cylinder 3. However, due to the presence of the outer shell, gas enters the shell through the opening in the outer shell, forming a vortex through the two through-holes and the inclined hole between the explosion cylinder (the inclined hole formed by the inclined groove and the air vent), thereby stirring the gas and achieving thorough mixing of the gas. At the endpoint, the sealing ring 8 at the connection between the valve stem 6 and the contact arm 5 blocks the through-hole 9, and at the same time, the wing plate 35, driven by the strip-shaped notch 36, rotates the safety plate 33 into the groove below the restriction hole 34, thereby releasing the trigger.
[0046] At this time, the trigger 28 is pulled, and the trigger 28 presses the spark igniter 31, which causes the spark plug 32 to ignite and generate a high-pressure spark that is sent into the mixed gas in the cavity formed by the explosion cylinder 3 and the cylinder cover 7, causing an explosion. The high-pressure gas generated by the explosion pushes the piston rod 37 to move left at high speed, driving the nail out of the body and into the fastened substrate, completing the firing.
[0047] After firing, high-temperature, high-pressure gas lifts valve disc 13 and vents through exhaust port 12. After being vented, valve disc 13 automatically rebounds, creating a temporary vacuum within cylinder body 2, drawing piston rod 37 rightward back to its original position. The gas gun leaves the fired base, and cylinder head 7, acted upon by return spring 11, moves leftward, simultaneously pushing the valve stem, contact arm, and nail tube leftward. The sealing ring on the left side of the valve stem leaves the through-hole, and exhaust gas is discharged through these two through-holes until cylinder head 7 returns to its leftmost end, completing a cycle.
