Description

Technical Field

[0001] This utility model belongs to the field of power tools, and specifically relates to a lithium-ion nail gun gas tank. Background Technology

[0002] Nail guns are a commonly used power tool in construction, renovation, and decoration processes. For example, patent application number 201811468946.5, entitled "A Portable Electric Nail Gun," illustrates this. As shown in the accompanying drawings, the cylinder and the piston chamber containing the piston assembly are interconnected. During long-term use, the piston assembly's sealing ring is prone to aging, or the piston position may deviate during motor-driven piston assembly movement. This can cause the high-pressure gas stored in the cylinder to leak from the piston position, reducing the density of the high-pressure gas within the cylinder. Consequently, the nail gun may not be able to drive the nails effectively, or the nailing efficiency may be significantly reduced, necessitating frequent and periodic replenishment of high-pressure gas into the cylinder. Utility Model Content

[0003] This utility model provides a lithium-ion battery nail gun gas storage tank to solve the technical problems existing in this field.

[0004] This utility model provides a lithium-ion nail gun gas tank to solve the above-mentioned technical problems, including a gun body and a cover; the cover is connected to the gun body to form a piston chamber and a gas storage chamber, and an openable damper is provided between the piston chamber and the gas storage chamber. The piston chamber is used to house the piston assembly, and the gas storage chamber is used to store high-pressure gas; when nailing is required, the damper is opened, so that the high-pressure gas in the gas storage chamber drives the piston assembly in the piston chamber to move at high speed to complete the nailing operation.

[0005] Furthermore, one end of the damper is pivotally connected to the gun body via a pivot shaft, and the other end of the damper is provided with a push rod. One end of the push rod is connected to the damper drive, and the other end of the push rod extends out of the gun body through a mounting hole provided on the gun body, so as to facilitate pushing the damper open from the outside of the gun body.

[0006] Furthermore, a sealing gasket is provided at the location where the air damper mates with the gun body.

[0007] Furthermore, a seal is provided between the push rod and the mounting hole of the gun body.

[0008] Furthermore, a cylindrical insert is provided inside the piston cavity. The cylindrical insert is injection molded from polyoxymethylene material or precision machined from metal tubing, which facilitates improved sealing between the cylindrical insert and the piston assembly.

[0009] Furthermore, the cover is provided with an air injection port.

[0010] This utility model relates to a gas storage tank for a lithium-ion nail gun, comprising a gun body and a cover. The cover, connected to the gun body, forms a piston chamber and a gas storage chamber. An openable damper is provided between the piston chamber and the gas storage chamber. The piston chamber houses a piston assembly, and the gas storage chamber stores high-pressure gas. When nailing is required, the damper is opened, allowing the high-pressure gas in the gas storage chamber to drive the piston assembly in the piston chamber at high speed to complete the nailing operation. Compared with existing technologies, by providing an openable damper between the piston chamber and the gas storage chamber, an obstruction is formed between them. When nailing is not needed, the high-pressure gas is stored in the gas storage chamber. During nailing, the damper is opened to complete the nailing operation. After nailing is completed, the damper closes again under the action of the high-pressure gas in the gas storage chamber, reducing the risk of high-pressure gas leakage from the piston assembly and piston chamber mating point. This allows for long-term storage of high-pressure gas in the lithium-ion nail gun's gas storage chamber, improving the efficiency of the nail gun. Attached Figure Description

[0012] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." The following descriptions are preferred embodiments of the present invention; however, these descriptions are intended to illustrate the general principles of the invention and are not intended to limit its scope. The scope of protection of this invention is determined by the appended claims.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings. The directional terms such as "upper", "lower", "left", "right", "inner" and "outer" described in the specification are only for better understanding and explanation, and are not intended to limit the present invention.

[0014] like Figure 1-4As shown, a lithium-ion nail gun gas tank includes a gun body 1 and a cover 2. The cover 2 is connected to the gun body 1 to form a piston chamber 1a and a gas storage chamber 1b. An openable damper 1c is provided between the piston chamber 1a and the gas storage chamber 1b. The piston chamber 1a is used to house the piston assembly, and the gas storage chamber 1b is used to store high-pressure gas. When nailing is required, the damper 1c is opened, so that the high-pressure gas in the gas storage chamber 1b pushes the piston assembly in the piston chamber 1a to move at high speed to complete the nailing operation.

[0015] Preferably, one end of the damper 1c is pivotally connected to the gun body 1 via a rotating shaft, and the other end of the damper 1c is provided with a push rod 1d. One end of the push rod 1d is drivenly connected to the damper 1c, and the other end of the push rod 1d extends out of the gun body 1 through a mounting hole provided on the gun body 1, so as to facilitate pushing the damper 1c to open from the outside of the gun body 1.

[0016] like Figure 3 and Figure 4 As shown, the cover 2 is located at the rear end of the gun body 1, and the gun body 1 has a gun frame 4 at the front end. A drive bracket 5 and a gun barrel 6 are movably mounted on the gun frame 4. A nail cartridge 7 is also detachably mounted on the gun frame 4. A drive rod 5a is mounted on the drive bracket 5, and a return spring 5b is located between the drive bracket 5 and the gun frame 4. A piston assembly 3 is located within the piston chamber 1a. When nailing is required, the gun barrel 6 is aligned with the desired nailing position and pressed down. The gun barrel 6 pushes the drive bracket 5 to overcome the resistance of the return spring 5b and move towards the end of the gun body 1 where the cover 2 is located. At this time, the drive rod 5a drives the push rod 1d to move, causing the air damper 1c to open, connecting the gas storage chamber 1b with the piston chamber 1a. When the trigger is pulled, the drive device on the piston assembly 3 continues to rotate, releasing the piston assembly 3. Furthermore, the high-pressure gas stored in the gas storage chamber 1b drives the piston assembly 3 to move at high speed, delivering the nail cartridge 7 to the position of the gun barrel 6 and driving the nail into the workpiece to be nailed. Simultaneously with nailing, the barrel 6 is released, and the drive bracket 5 and barrel 6 are reset by the return spring 5b. At this time, the damper 1c is also closed by the high-pressure gas in the gas storage chamber 1b, awaiting the next nailing operation. Therefore, by setting an openable damper 1c between the piston chamber 1a and the gas storage chamber 1b, an obstruction can be formed between the piston chamber 1a and the gas storage chamber 1b. When nailing is not required, the high-pressure gas is stored in the gas storage chamber 1b. During nailing, the damper 1c is opened to complete the nailing operation. After nailing is completed, the damper 1c is closed again by the high-pressure gas in the gas storage chamber 1b, reducing the risk of high-pressure gas leakage from the mating position of the piston assembly 3 and the piston chamber 1a. This allows the high-pressure gas in the gas storage chamber 1b of the lithium-ion nail gun to be stored for a long time, improving the efficiency of the nail gun.

[0017] More preferably, a sealing gasket 1e is provided at the mating position between the air damper 1c and the gun body 1. The sealing gasket 1e can be embedded in the air damper 1c. Similarly, to ensure the sealing between the gun body 1 and the cover 2, a sealing ring is also provided at the mating position between the gun body 1 and the cover 2, which is not shown in the attached drawings.

[0018] More preferably, a sealing element 1d1 is provided between the push rod 1d and the mounting hole of the gun body 1, which can make the push rod 1d fit more tightly with the mounting hole and prevent high-pressure gas leakage.

[0019] More preferably, a cylindrical insert 1a1 is provided inside the piston cavity 1a. The cylindrical insert 1a1 is injection molded from polyoxymethylene material. The use of polyoxymethylene material in the cylindrical insert 1a1 has self-lubricating properties, which can enhance the sealing performance between the piston assembly and the cylindrical insert 1a1. Alternatively, the cylindrical insert 1a1 can be precision machined from a metal tube. Precision machining of the metal tube can improve the smoothness and roundness of its inner wall, which also facilitates the improvement of the sealing performance between the cylindrical insert 1a1 and the piston assembly.

[0020] More preferably, the cover 2 is provided with an air injection port 2a, which can be used to replenish the high-pressure gas in the gas storage chamber 1b in a timely and effective manner when the high-pressure gas is lost, so that the lithium-ion steel nail gun is always in a highly efficient and usable state.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
