Description

Technical Field

[0001] This utility model belongs to the field of air gun technology, and in particular relates to an air gun with a matching quick-release air chamber structure. Background Technology

[0002] An air gun is a gas-powered device. The gas is contained in a gas cylinder, which is installed in the air chamber structure to expel gas when the trigger is pulled, thus providing power to the bullet. Since the gas in the cylinder is a consumable, it needs to be replaced when it runs out to replenish the power. However, existing air chamber structures are complex, making it difficult to quickly replace the gas cylinder.

[0003] Specifically: See Figure 1 and Figure 2 As shown, in the existing air chamber structure 1', the gas cylinder 12' is installed inside the air chamber core 11. The air chamber core 11' is threadedly connected to the gas cylinder hanger 2'. The gas cylinder hanger 2' is also connected to the handle system 3'. The handle system 3' drives the gas cylinder hanger 2' and the air chamber structure 1' to move backward and hook onto the gas cylinder lock 4'. After the trigger 51' of the storage box system 5' is pulled, the gas cylinder hanger 2' disengages from the gas cylinder lock 4' and moves forward to expel gas, providing power to the bullet. In addition, the air chamber structure 1' is also indirectly inserted into the barrel 8' through the gas cylinder outer tube 6' and the outer tube cap 7'. However, the opening 61' of the gas cylinder outer tube 6' is small, and the assembled air chamber structure 1' and gas cylinder hanger 2' cannot be disassembled or assembled through this opening 61'. The process of replacing the existing gas chamber structure is as follows: Disassembly: After removing the stud 9' connecting the barrel 8' and the storage box system 5', remove the storage box system 5' and the barrel 8'. Then unscrew the air pump head 10' located at the front end of the gas chamber structure 1' to remove the gas chamber structure 1' and replace the gas cylinder located inside the gas chamber structure 1'. Reassembly: Take the handle system 3', then take the gas chamber structure 1' with the replaced gas cylinder and the air pump hanger 2' and connect them to the handle system 3'. Then take the air pump head 10' and connect it to the threaded connection at the front end of the handle system 3' to restrict the gas chamber structure 1' and the air pump hanger 2' within the handle system 3'. Take the barrel 8' with the air pump outer tube 6' and outer tube cap 7' and slide it into the assembled handle system 3' from right to left. Finally, take the storage box system 5' and place it in the corresponding position, and take the stud 9' and tighten it in the corresponding position. Summary of the Invention

[0004] The purpose of this utility model is to provide an air gun with a matching quick-release air chamber structure, which makes air cylinder replacement simpler and faster by improving the structure of the air gun.

[0005] To achieve the objectives of this utility model, the technical solution of this utility model includes: An air gun with a quick-release air chamber structure is provided. The air gun includes an air chamber structure and an air cylinder hanger. An air cylinder is installed inside the air chamber structure. The air chamber structure and the air cylinder hanger are magnetically connected. The air chamber structure is installed inside the outer tube of the air cylinder. The side wall of the outer tube of the air cylinder is provided with a disassembly port through which the air chamber structure can pass. Thus, the air chamber structure can be detached from the air cylinder hanger by means of the magnetic connection and can be disassembled and assembled by means of the disassembly port.

[0006] In one embodiment, the outer tube of the air cylinder is provided with an outer tube cover at the disassembly port. One side of the outer tube cover is hinged to the outer tube of the air cylinder, and the other side is connected to the outer tube of the air cylinder by elastic snap-fit.

[0007] In one embodiment, the outer tube cap and the outer tube of the air cylinder are hinged together by means of two sets of hinge lock assemblies. The hinge lock assembly includes a first hinge lock member and a second hinge lock member, which are a transmission connection with a shaft hole structure. The first hinge lock member is fixedly connected to the outer tube of the air cylinder, and the second hinge lock member is fixedly connected to the outer tube cap. The outer tube cap and the outer tube of the air cylinder are elastically connected by means of a snap-fit ​​between a switch lock member and a spring buckle. The switch lock member is fixedly connected to the outer tube cap, and the spring buckle is elastically connected to the outer tube of the air cylinder by means of a spring. The switch lock member and the spring buckle are respectively provided with hooks to form a snap-fit ​​between the switch lock member and the spring buckle.

[0008] In one embodiment, the end of the spring buckle is a first snap-fit ​​portion, which includes a first inclined section and a concave corner section, and the end of the switch lock is a second snap-fit ​​portion, which includes a second inclined section and a convex corner section. Thus, the first snap-fit ​​portion and the second snap-fit ​​portion form a snap-fit ​​engagement, and the convex corner section engages with the first inclined section to create an installation clearance for the elastic buckle.

[0009] In one embodiment, the end of the air chamber structure facing the air pump hanger is provided with an air pump screw, which is made of metal. The air pump hanger is connected to a magnet, and the air chamber structure and the air pump hanger are magnetically connected by means of the air pump screw and the magnet.

[0010] In one embodiment, the end of the air pump hanger facing the air chamber structure is provided with a magnet fixing member, the magnet is installed on the magnet fixing member, and the end of the magnet fixing member facing the air chamber structure is provided with a frustum-shaped guide portion. At least a portion of the guide portion is inserted into the air pump screw and uses its sidewall to play a guiding role. The magnet is disposed on the end face of the guide portion and is magnetically connected to the air pump screw by means of the guidance of the guide portion. In one embodiment, the rear end of the air cylinder hanger is provided with an elastic element. The elastic force of the elastic element causes the front end of the air chamber structure to exceed the disassembly port of the air cylinder outer tube. The air chamber structure moves backward by compressing the elastic element so that it can pass through the disassembly port to achieve its disassembly and assembly.

[0011] In one embodiment, the gas chamber structure includes a barrel-shaped gas chamber core for mounting the gas cylinder. One end of the gas chamber core has a mounting hole. Along the length of the gas chamber core, an inlet valve core and a gas cylinder screw are sequentially connected to the mounting hole. The inlet valve core is screwed into the gas chamber core, and the gas cylinder screw is screwed into the inlet valve core. The outlet end of the gas cylinder is mounted on the inlet valve core, and the other end of the gas cylinder abuts against the bottom of the gas chamber core. A nozzle is provided inside the gas cylinder screw, and the gas in the gas cylinder is ejected through the nozzle to serve as the launch power.

[0012] The advantages of this utility model are as follows: By setting the air chamber structure and the air cylinder hanger to a magnetic connection, the air chamber structure can be separated from the air cylinder hanger when it is disassembled or assembled, that is, the air chamber structure can be disassembled independently. Furthermore, a disassembly and assembly port is opened on the outer tube of the air cylinder for the air chamber structure to enter and exit. The air chamber structure can be disassembled and assembled through this disassembly and assembly port, thereby replacing the air cylinder, simplifying the operation steps of replacing the air cylinder and realizing the rapid replacement of the air cylinder.

[0023] See Figure 3 and Figure 4 As shown, this utility model discloses an air gun with a quick-release air chamber structure. The air gun includes an air chamber structure 1 and an air cylinder hanger 2. An air cylinder 11 is installed inside the air chamber structure 1. The air chamber structure 1 and the air cylinder hanger 2 are magnetically connected. The air chamber structure 1 is installed inside the outer tube 3 of the air cylinder. The side wall of the outer tube 3 of the air cylinder is provided with a disassembly port 31 through which the air chamber structure 1 can pass. Thus, the air chamber structure 1 can be detached from the air cylinder hanger 2 by means of magnetic connection and can be disassembled and assembled by means of the disassembly port 31, so as to facilitate the replacement of the air cylinder 11 inside the air chamber structure 1.

[0024] Compared to traditional methods where the air chamber structure 1 and air cylinder bracket 2 are connected by screws and can only be disassembled from the end of the barrel, this invention magnetically connects the air chamber structure 1 to the air cylinder bracket 2. This allows the air chamber structure 1 to be detached from the side and separated from the air cylinder bracket 2. The air chamber structure 1 can then be removed separately from the disassembly port 31 of the outer tube 3 of the air cylinder, thus achieving the disassembly and assembly of the air chamber structure 1. Furthermore, since the air cylinder is installed inside the air chamber structure 1, the removed air chamber structure 1 can be disassembled to replace the air cylinder, thereby reducing the number of steps required for air cylinder replacement and improving the efficiency of air cylinder replacement.

[0025] In one embodiment, an outer tube cover 4 is provided at the disassembly port 31 of the air cylinder outer tube 3. One side of the outer tube cover 4 is hinged to the air cylinder outer tube 3, and the other side is connected to the air cylinder outer tube 3 by an elastic snap-fit. By operating the elastic snap-fit, the outer tube cover 4 can be flipped around the hinge between it and the air cylinder outer tube 3, thereby opening or closing the disassembly port 31. More specifically, when the elastic snap-fit ​​is locked, the outer tube cover 4 covers the disassembly port 31 of the air cylinder outer tube 3, and the air chamber structure 1 cannot be disassembled or installed through the disassembly port 31. When the elastic snap-fit ​​is unlocked, the outer tube cover 4 can be flipped to expose the disassembly port 31, so that the air chamber structure 1 can be removed from the disassembly port 31 for disassembly, or the air chamber structure 1 can be installed into the air cylinder outer tube 3 from the disassembly port 31.

[0026] See Figures 4 to 7 As shown, in this embodiment, the outer tube cover 4 and the outer tube of the air cylinder 3 are hinged together by means of two sets of hinge lock assemblies 5. The hinge lock assembly 5 includes a first hinge lock 51 and a second hinge lock 52. The first hinge lock 51 and the second hinge lock 52 are a transmission connection with a shaft hole structure. One end of the first hinge lock 51 is fixedly connected to the outer tube of the air cylinder 3 by a screw, and the other end is a short shaft 511. One end of the second hinge lock 52 is fixedly connected to the outer tube cover 4 by a screw, and the other end is provided with a round hole 521. The short shaft 511 is inserted into the round hole 521 to form a shaft hole fit, thereby forming a hinge between the outer tube cover 4 and the outer tube of the air cylinder 3.

[0027] In addition, the outer tube cover 4 and the outer tube of the air cylinder 3 are also elastically connected by the snap-fit ​​between the switch lock 62 and the spring buckle 61. The switch lock 62 is fixedly connected to the outer tube cover 4, and the spring buckle 61 is elastically connected to the outer tube of the air cylinder 3 by the spring 63. The switch lock 62 and the spring buckle 61 are respectively provided with snap-fit ​​parts to form the snap-fit ​​between the switch lock 62 and the spring buckle 61. The end of the spring buckle 61 is a first snap-fit ​​portion 611, which includes a first inclined section 6111 and a concave corner section 6112. The end of the switch lock 62 is a second snap-fit ​​portion 621, which includes a second inclined section 6211 and a convex corner section 6212. The concave corner section 6112 and the convex corner section 6212 are a convex-concave mating structure with corresponding shapes, so that the first snap-fit ​​portion 611 and the second snap-fit ​​portion 621 form a snap-fit ​​engagement. The convex corner section 6212 and the first inclined section 6111 cooperate to form an installation clearance for the elastic buckle. During the process of the outer tube cover 4 flipping from the open to the closed state, the convex corner section 6212 abuts against the first inclined section 6111, and as the outer tube cover 4 flips, the convex corner section 6212 applies pressure to the spring buckle 61 through the first inclined section 6111. This pressure has a component along the deformation direction of the spring 63, that is, this pressure pushes the spring 63 to compress, thereby pushing the spring buckle 61 to retract and give way to the convex corner section 6212, until the convex corner section 6212 disengages from the first inclined section 6111 and engages with the concave corner section 6112. Under the elastic force of the spring 63, the spring buckle 61 is reset, and the locking between the concave corner section 6112 and the convex corner section 6212 is used to form a lock between the air cylinder outer tube 3 and the outer tube cover 4.

[0028] See Figure 3 As shown, to form a magnetic connection between the air chamber structure 1 and the air pump hanger 2, an air pump screw 12 is provided at the end of the air chamber structure 1 facing the air pump hanger 2. The air pump screw 12 is made of magnetic metal. A magnet 21 is connected to the air pump hanger 2. The air chamber structure 1 and the air pump hanger 2 are magnetically connected by means of the air pump screw 12 and the magnet 21. A magnet fixing member 22 is provided at one end of the air pump hanger 2 facing the air chamber structure 1. The magnet 21 is installed on the magnet fixing member 22. A frustum-shaped guide portion 221 is provided at one end of the magnet fixing member 22 facing the air chamber structure 1. At least a portion of the guide portion 221 is inserted into the air pump screw 12 and uses its sidewall to provide guidance. The magnet 21 is located on the end face of the guide portion 221 and is magnetically connected to the air pump screw 12 by means of the guidance of the guide portion 221. The presence of the guide part 221 makes the connection between the air chamber structure 1 and the air cylinder hanger 2 more accurate and stable. The side guidance of the guide part 221 facilitates the quick connection between the air chamber structure 1 and the air cylinder hanger 2. Furthermore, the insertion of the end of the guide part 221 into the air cylinder screw 12 can improve the stability of the connection between the two, thereby improving the connection stability between the air chamber structure 1 and the air cylinder hanger 2.

[0029] This embodiment relies on a magnet and a magnetic metal cylinder screw 12 to form a magnetic connection. The magnet is placed on the cylinder hanger 2, and the magnetic metal is placed on the cylinder chamber structure 1. This prevents the cylinder chamber structure 1 from attracting other parts due to magnetism during the disassembly, assembly, and replacement of the cylinder 11, thus preventing undesirable magnetic attraction. If a magnet were placed at the end of the cylinder chamber structure 1, it is possible that other metal parts, such as gun barrels, would be attracted to it during the disassembly, assembly, and replacement of the cylinder.

[0030] See Figure 1 , Figure 8 and Figure 9 As shown, the rear end of the air pump attachment 2 is provided with an elastic element 7 (the installation method of the elastic element 7 in this embodiment is the same as...). Figure 1 The prior art shown is the same, and the elastic element 7 can be seen in Figure 1). In this embodiment, the elastic element 7 is a helical spring. The elastic force of the elastic element 7 causes the front end of the air chamber structure 1 to exceed the disassembly port 31 of the outer tube 3 of the air cylinder. The air chamber structure 1 moves backward by compressing the elastic element 2 so that it can pass through the disassembly port 31 to realize its disassembly and assembly.

[0031] When it is necessary to remove the air chamber structure 1, apply force to the spring buckle 61 on the outer tube 3 of the air cylinder to move it away from the switch lock 62, thereby disengaging the two. Then, flip the outer tube cover 4 to open the disassembly port 31 of the outer tube 3 of the air cylinder, move the air chamber structure 1 forward to detach it from the air cylinder hanger 2, and then remove the rear end of the air chamber structure 1 from the disassembly port 31 until the air chamber structure 1 is completely removed from the disassembly port 31, so that the gas cylinder 11 inside the air chamber structure 1 can be replaced. When it is necessary to install the air chamber structure 1, insert the rear end of the air chamber structure 1 into the disassembly port 31 and magnetically connect the rear end to the air cylinder hanger 2. Then, push the air chamber structure 1 backward to compress the elastic element 7 until the air chamber structure 1 is completely inserted into the disassembly port 31.

[0032] See Figure 3As shown, the gas chamber structure 1 also includes a barrel-shaped gas chamber core 13, which is used to install a gas cylinder 11. One end of the gas chamber core 13 has a mounting hole. Along the length of the gas chamber core 13, an air inlet valve core 14 and a gas cylinder screw 15 are connected in sequence at the mounting hole. The outlet end of the gas cylinder 11 is inserted into the air inlet valve core 14, and the other end of the gas cylinder 11 abuts against the gas cylinder screw 12 at the bottom of the gas chamber core 13. A gas nozzle 16 is provided inside the gas cylinder screw 15. The gas in the gas cylinder 11 is ejected through the gas nozzle 16 and used as the launch power. The intake valve core 14 is screwed onto the inner core 13 of the gas chamber, and the gas cylinder screw 15 is screwed onto the intake valve core 14. When the gas cylinder 1 needs to be replaced, the intake valve core 14 is removed from the inner core 13 of the gas chamber, and the used gas cylinder 11 can be removed. Then, the gas cylinder 11 filled with carbon dioxide gas is inserted into the intake valve core 14, and the intake valve core 14 with the gas cylinder screw 15 and the nozzle 16 is screwed onto the inner core 13 of the gas chamber, so that the gas cylinder 11 can be installed and the gas cylinder 11 can be replaced.

[0033] The gas cylinder 11 is an existing technology and will not be described in detail here.

[0034] Other unmentioned parts are existing technology.
