Description

Technical Field

[0001] The utility model relates to the technical field of hand-held nail guns, and more specifically, to a heat insulation component of a nail gun and a nail gun. Background Art

[0002] As an efficient and precise tool, the axial nail gun is gradually favored by the majority of professionals. Its unique working principle and wide application range play an irreplaceable role in improving production efficiency and ensuring project quality. The axial nail gun is a tool that quickly and accurately shoots nails into the target material through axial force. It uses the instantaneous impact force generated by high-pressure gas or spring energy storage to push the nail out at high speed along the axial direction, thereby realizing the fastening of various materials such as wood, metal, and concrete. This working method not only greatly saves manpower and time but also ensures the accuracy of the penetration depth and angle of the nail.

[0003] Heat insulation of the nail gun is particularly important. Poor heat insulation performance will cause the temperature of the nail gun housing to rise rapidly. In the existing technology, the nail tube of the nail gun is usually in direct or indirect contact with the housing, with a large contact area. The temperature generated after the firing of the nail gun is directly transmitted to the housing through the metal, which is very likely to cause burns to the user. Summary of the Invention

A fourth ring 284 is coaxially and integrally connected to the seat platform 285. The fourth ring 284 supports at the end of the eighth tube body 262. A guiding tube section 281 is coaxially and integrally connected to the fourth ring 284. The guiding tube section 281 is hollow inside and is used to accommodate the pin body 252 and the pin tip 253 of the firing pin 250. The pin body 252 and the pin tip 253 of the firing pin 250 can telescopically move along the length direction of the guiding tube section 281 inside the guiding tube section 281. A stop block 282 is provided inside the end of the guiding tube section 281. The center of the stop block 282 has a needle hole 283, and the needle hole 283 is adapted for the pin tip 253 to pass through.

[0076] During the energy storage process of the first spring 240, the socket 210 approaches the seat body 260 and extends into the first through groove 265 of the seat body 260. The trigger part 215 at one end of the socket 210 will contact the safety pin 231 of the safety device 230. The trigger part 215 then pushes the safety pin 231 to move into the second groove 226. When the safety pin 231 completely enters the second groove 226, the energy stored in the first spring 240 is instantly released, pushing the entire shaft rod 220 to slide in the second through groove 266, and then pushing the firing pin 250 to move in the first direction to strike the bottom shell of the nail 400. In the technical solution of the present application, through the cooperation of the first through groove 265, the second through groove 266, the safety device 230 and the trigger part 215, the firing process is completed. There is no need to open a sliding groove on the socket 210, which not only solves the jamming problem of the firing pin caused by the sliding groove, but also reduces the processing cost.

[0107] Working Principle

[0108] When the nail gun starts to work, load the nail 400 into the nail tube 150 and align it with the place where the nail 400 needs to be fixed.

[0109] As Figure 15 - Figure 16 shown, the firing process:

[0110] S1: Load the nail 400 into the nail tube 150 and align it with the place where it needs to be fixed;

[0111] S2: Hold the housing assembly 300 by hand and push it in the first direction, so that the housing assembly 300 and its connected firing assembly 200 slide along the first direction, and the third spring 140 starts to be compressed and store energy;

[0112] S3: After the needle tube 280 of the firing assembly 200 contacts the bottom shell of the nail 400, stop moving in the first direction; and the housing assembly 300 continues to slide along the first direction, and the second spring 270 starts to be compressed and store energy;

[0113] S4: The safety pin 231 of the safety device 230 contacts and gets stuck at the bottom of the first through groove 265 of the seat body 260, and drives the first spring 240 to start storing energy;

[0114] S5: The fourth tube body 211 of the tube seat 210 extends into the first through groove 265, and its triggering part 215 contacts the safety pin 231, pushing the safety pin 231 to move and enter the second groove 226;

[0115] S6: The first spring 240 instantaneously releases the stored energy, pushing the shaft rod 220 to slide in the second through groove 266, and then pushing the firing pin 250 to strike the bottom shell of the nail 400, completing the firing of the nail 400;

[0116] S7: Release the housing assembly 300, and the third spring 140 starts to release the stored energy, resetting the silencer support 130 and the limiting body 110;

[0117] S8: The second spring 270 starts to release the stored energy, causing the shaft rod 220 to slide back in the second direction, and the safety pin 231 exits the second through groove 266 and returns to the first through groove 265 again.

[0118] Grip the housing assembly 300 of the nail gun and axially push the housing assembly 300 in the first direction. The housing assembly 300 and the firing assembly 200 connected thereto slide along the first direction, and at the same time, the third spring 140 starts to be compressed and store energy. During the energy storage process of the first spring 240, the needle tube 280 of the firing assembly 200 will first contact the bottom shell part of the nail 400 (the other end of the nail 400 is pressed against the wall). As the housing assembly 300 continues to move in the first direction, the firing assembly 200 stops moving in the first direction under the block of the bottom shell of the nail 400. At this time, as the housing assembly 300 continues to move in the first direction, taking the housing assembly 300 as a reference, the firing assembly 200 moves in the second direction relative to the housing assembly 300, and at this time, the second spring 270 starts to store energy. During the energy storage process of the second spring 270, the safety pin 231 of the safety device 230 will contact and get stuck at the bottom of the first through groove 265 of the seat body 260, and then drive the first spring 240 to start storing energy. During the energy storage process of the first spring 240, the fourth tube body 211 of the tube seat 210 extends into the first through groove 265 of the seat body 260, and finally makes the trigger part 215 of the tube seat 210 contact the safety pin 231 of the safety device 230. The trigger part 215 pushes the safety pin 231 to move into the second groove 226. When the safety pin 231 completely enters the second groove 226, the energy stored in the first spring 240 is instantly released, pushing the entire shaft rod 220 to slide in the second through groove 266, and then pushing the firing pin 250 to move in the first direction and strike the bottom shell of the nail 400.

[0119] Reset process after firing

[0120] After firing, release the housing assembly 300. The third spring 140 starts to release the stored energy, causing the silencer support 130 and the limit body 110 to reset. The second spring 270 starts to release the stored energy, causing the shaft rod 220 to slide back in the second direction, and making the safety pin 231 return from the second through groove 266 to the first through groove 265 again, completing the entire reset.
