Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, specifically to a nail gun guide mechanism. Background Technology

[0002] A nail gun, also known as a nailing device, is often called a nail gun because its shape and principle are similar to a pistol. It is a fastening tool that uses blank cartridges, gas, or compressed air as power to drive nails into the building structure. Nail guns are used for nail fastening technology, which is an advanced modern fastening technology with many advantages, such as being self-powered, thus eliminating the burden of wires and ducts, facilitating on-site and high-altitude operations, quick operation, short construction period, greatly reducing the labor intensity of workers, reliable and safe operation, and nail guns are usually equipped with a guide mechanism at the exit position.

[0003] The existing guide structure mainly consists of a guide plate. The hollow guide plate can limit the direction of the nails fired from the nail gun, preventing the nails from deviating during the firing process. When using the nail gun, the guide plate needs to be manually pressed tightly against the surface of the board to prevent the nails from deviating during the output process. When manually pressing and supporting the nails during the firing process, the arm may shake, which will cause gaps to appear at the joint between the end of the guide plate and the board. This will cause the nails to deviate during the firing process and affect the nail fixing effect. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-5 This embodiment provides a technical solution: a nail gun guiding mechanism, including a nail gun body 1, a nail clip 4, a guide plate 2, and a fixing part 3. The bottom connecting pipe of the nail gun body 1 is connected to a cylinder, which serves as the power source to drive the nail into the building structure. The guide plate 2 is fixed to the output end of the nail gun body 1 and is connected to the nail gun body 1 by bolts. The guide plate 2 can guide the nail and ensure the direction of nail ejection. The fixing part 3 is disposed above the guide plate 2 and has the function of fixing the nail to the guide plate. A fixing plate 301 is located above the guide plate 2. The fixing plate 301 is connected to the guide plate 2 by bolts, which facilitates the disassembly or installation of the fixing plate 301 by the workers. A connecting plate 302 is fixed on the side of the output end of the nail gun body 1. The connecting plate 302 is connected to the fixing plate 301 by bolts, which improves the stability of the overall structure. The connecting plate 302 is U-shaped and has a ventilation hole 303 on the recessed side. The ventilation hole 303 is square and there are two sets of ventilation holes 303.

[0034] A suction cup 304 is fixedly mounted on the connecting plate 302 at the output end of the guide plate 2, and the hole in the suction cup 304 coincides with the position of the ventilation hole 303. The suction cup 304 is connected to the connecting plate 302 by adhesive. A first spring 305 is connected inside the connecting plate 302 by a connector, and a pull rod 306 is connected to the top of the first spring 305 by a connector. The first spring 305 has a design with two circular rings at both ends, and each end of the circular ring of the first spring 305 is fitted with a buckle. The buckles fitted on the first spring 305 are connected to the connecting plate 302 and the pull rod 306. Figure 5In its undeformed state, the vertical movement of the pull rod 306 causes the first spring 305 to deform. A sealing plate 307 is fixedly installed at the bottom of the pull rod 306, and the sealing plate 307 is slidably connected to the ventilation hole 303. The sealing plate 307 is connected to the pull rod 306 by bolts. The movement of the pull rod 306 can drive the sealing plate 307 to move in the same way. A sliding frame 308 is slidably connected to one side of the output port of the guide plate 2. The sliding frame 308 is a square frame and houses the output port of the guide plate 2 inside. The vertical movement of the pull rod 306 causes the first spring 305 to deform and drives the sealing plate 307 to move vertically inside the connecting plate 302. The nail clip 4 is fixedly installed at the bottom of the guide plate 2 and is connected to the guide plate 2 by bolts. The nail clip 4 can be used to store nails.

[0035] Example 2

[0036] Please see Figure 1-5 The fixing part 3 also has a guide block 311 fixed to the front side of the fixing plate 301. The guide block 311 is connected to the fixing plate 301 by welding to prevent the fixing plate 301 from separating from the guide block 311 due to external impact. The guide block 311 is located on one side of the sliding frame 308 and is connected to a second spring 309 by a connector. The other end of the second spring 309 is connected to the sliding frame 308 by a connector. The second spring 309 is connected to the sliding frame 308 and the guide block 311 by a buckle. Figure 2 When in an uncompressed state, the horizontal movement of the sliding frame 308 will cause the second spring 309 to deform. The second spring 309 can quickly push the sliding frame 308 back to its initial position. The bottom of the pull rod 306 is fixed with a sliding rod 313, and the sliding rod 313 is slidably connected to the connecting plate 302. The sliding rod 313 can limit the pull rod 306 to ensure the stability of the pull rod 306 during vertical movement. The sliding rod 313 is a cylinder and passes through the hole formed in the center of the first spring 305. The sliding rod 313 can limit the first spring 305 to reduce the deformation and misalignment of the first spring 305.

[0037] Protective plates 312 are fixed on both sides of the sliding frame 308, and the protective plates 312 are in contact with the guide block 311. The protective plates 312 can protect the second spring 309 and reduce the damage to the second spring 309 caused by external collisions. A guide rod 310 is fixed on one side of the sliding frame 308 and is slidably connected to the guide block 311. The guide block 311 can limit the sliding frame 308 and reduce the deviation of the guide block 311 during movement. There are two sets of guide blocks 311, and both sets of guide blocks 311 pass through the hole formed in the center of the second spring 309. The guide blocks 311 can limit the second spring 309 and reduce the deformation and misalignment of the second spring 309. A reinforcing plate 314 is fixed on the output side of the fixed plate 301 and is fixedly connected to the ventilation hole 303. The reinforcing plate 314 strengthens the overall structure and ensures the stability of the overall frame structure of the fixed part 3.

[0038] Working principle: First, when the device is needed, align the sliding frame 308 of the device with the position where the nail needs to be driven, and then press the sliding frame 308 forward. The sliding frame 308 will slide towards the output port of the guide plate 2 under pressure. After the sliding frame 308 slides, the suction cup 304 will adhere to the wall. Then continue to press the sliding frame 308, and the suction cup 304 will gradually deform and squeeze out the air inside. The air inside the suction cup 304 decreases and the pressure decreases. Under the action of atmospheric pressure, the suction cup 304 adheres tightly to the board. The guide plate 2 can be fixed by the two sets of suction cups 304 to prevent the guide plate 2 from shifting before the nail is shot out. Then press the switch of the nail gun body 1 to shoot the nail out from the outlet of the guide plate 2.

[0039] Secondly, when it is necessary to release the suction cup 304, manually pull the lever 306 upward. The movement of the lever 306 will cause the sealing plate 307 to move downward. The sealing gasket on the surface of the sealing plate 307 will no longer block the ventilation hole 303. At this time, the external gas will enter the suction cup 304 through the ventilation hole 303, so that the pressure inside the suction cup 304 is restored. Then, pull the nail gun body 1 outward to separate the suction cup 304 from the plate.
