Description

A nail gun suitable for blunt-head stainless steel threaded nails Technical Field

[0001] This utility model relates to the field of nail gun equipment technology, specifically a nail gun suitable for blunt-headed stainless steel threaded nails. Background Technology

[0002] Cold-joint fastening technology using nail guns is a direct fastening technique. It utilizes a nail gun to fire a nail cartridge, causing the propellant inside to burn and release energy, which in turn drives the piston of the nail gun, driving the nail directly into a substrate such as steel or concrete. This permanently or temporarily secures components that need to be fixed, such as gratings, checkered plates, and supports. It is widely used in petrochemical refineries, oil platforms, power plants, chemical plants, and industrial plants.

[0003] Currently, most nail guns on the market require the operator to manually pull the front part of the nail gun after each shot to remove the cartridge and reset it. This manual operation method is not only cumbersome and inefficient, but also has limitations.

[0004] The reason for this problem is that after each shot, operators need to spend a lot of time and energy manually retrieving and resetting the nail. In continuous operation scenarios, frequent manual operation can easily distract attention, leading to delays in the overall construction progress. Furthermore, the spring inside the nail gun typically has significant elasticity to ensure firing power. When manually pulling the front part to reset, the operator needs to overcome considerable spring resistance, which can easily cause hand and arm muscle fatigue over prolonged operation, presenting limitations. Therefore, we propose a nail gun suitable for blunt-tipped stainless steel threaded nails to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a nail gun suitable for blunt-tipped stainless steel threaded nails.

The trigger assembly 5 includes a trigger 5-1, a lever pressure block 5-2, a positioning pin 5-3, and a positioning ring 5-4. The upper end face and one side face of the trigger 5-1 are... Each component has an opening. A T-shaped lever pressure block 5-2 is inserted into the opening on the upper surface of the trigger 5-1. The upper surface of the lever pressure block 5-2 is connected to the lower surface of a U-shaped positioning retainer 5-5 by a positioning pin 5-3. Positioning sleeves 5-4 are installed in the through holes on the two side walls of the positioning retainer 5-5. A push rod 5-6 is inserted into the through hole at the lower part of the lever pressure block 5-2, and the push rod 5-6 is riveted to the lever pressure block 5-2. One end of the push rod 5-6, which protrudes from the lever pressure block 5-2, is inserted into the opening on the side of the trigger 5-1. The firing pin seat assembly 6 includes a firing pin 6-1, a firing pin spring 6-2, a firing push rod 6-3, a firing pin seat body 6-5, a feed lever 6-6, and a lever transmission rod 6-7. The firing pin seat body 6-5 is mounted along its axis. A through hole is provided along the linear direction, and a firing pin 6-1 is installed at the front of the through hole. The front end of the firing pin 6-1 contacts the rear end of the firing push rod 6-3, and the rear end of the firing pin 6-1 is connected to the front end of the firing pin spring 6-2. The rear end of the firing pin spring 6-2 is connected to the firing pin seat 6-5. An L-shaped feed lever 6-6 is provided on the side of the firing pin seat 6-5. The shorter end of the feed lever 6-6 is located inside the firing pin seat 6-5, and the longer end of the feed lever 6-6 contacts the nail cartridge clip 8. A round hole is provided at the shorter end of the lever transmission rod 6-7, and the round hole mates with a circular boss at the center of the shorter end of the feed lever 6-6. The longer end of the lever transmission rod 6-7 contacts the lever pressure block 5-2.

[0040] In this embodiment, the method of using the nail gun is as follows: First, insert the blunt-tipped stainless steel threaded nail 9 into the tapered inner hole at the front of the nail tube assembly 1 to accurately fix the blunt-tipped stainless steel threaded nail 9; insert the nail cartridge clip 8 from the bottom of the handle assembly 7, at which time the longer end of the feed lever 6-6 contacts the nail cartridge clip, and the nail cartridge is located behind the through hole along the axial direction of the cylindrical frame 4-4 and contacts the front end of the firing pin 6-1; then move the nail gun to the location where the steel grating plate needs to be installed and fastened, and hold it by hand. Align component 7 with the blunt-tipped stainless steel threaded nail 9 in the pre-hole on the steel grating. At this time, the blunt-tipped stainless steel threaded nail 9 drives the nail tube assembly 1 to be compressed in the opposite direction, and the firing tube assembly 2 moves backward. The rear end face of the firing tube assembly 2 contacts the front end of the push rod 5-6 and moves it backward, pushing the installation firing pin 6-1 to the compression position. The installation firing pin 6-1 is locked by the firing block 6-4 and is in the ready-to-fire state. The firing push rod 6-3 is attached to the firing block 6-4, and the lever pressure block 5-2 is attached to the lever transmission rod 6-7.

[0041] When the trigger is pulled, the lever pressure block 5-2 sequentially moves the lever transmission rod 6-7, the feeding lever 6-6, and the nail cartridge clip 8, achieving automatic cartridge feeding. Simultaneously, the lever pressure block 5-2 also sequentially moves the push rod 5-6 and the firing block 6-4, causing the firing pin 6-1 to fire. The firing pin 6-1 pushes the nail cartridge in the clip, causing the propellant inside to explode and generate kinetic energy. The propellant passes through the through hole in the cylindrical frame 4-4 and sequentially pushes the firing tube, piston rod, and blunt-headed stainless steel threaded nail 9 forward, causing the blunt-headed stainless steel threaded nail 9 to penetrate the substrate, completing the installation and fastening of the steel grating. The distance the firing tube moves along its axis is limited by the stop block on the positioning block; therefore, the firing tube only moves forward a certain distance before stopping.

[0042] After the nail gun completes its fastening and leaves the base, the firing tube assembly 2 and the firing pin 4-3 automatically reset sequentially under the action of the rectangular return spring 2-1. Simultaneously, the firing pin 6-1 is installed, and the limiting spring drives the cartridge feeder 6-6 and the trigger transmission rod 6-7 to reset. The trigger transmission rod 6-7 then drives the trigger pressure block 5-2 back to its original position, thus resetting the trigger. At the same time, the trigger pressure block 5-2 drives the firing pin 5-6 to reset, achieving automatic reset of the nail gun. After reinstalling the blunt-head stainless steel threaded nail 9 and the nail cartridge clip 8, the next installation and fastening operation of the steel grating can be performed, thus realizing the functions of fixing, striking, automatically feeding, and automatically resetting the blunt-head stainless steel threaded nail 9.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
