Description

Technical Field

[0001] This utility model relates to the field of nail installation gun technology, and in particular to a pneumatic underfloor heating nail installation gun. Background Technology

[0002] Underfloor heating is a heating system that uses the entire floor as a heat dissipation surface to evenly radiate heat into the room through a heating system buried underground. Its core principle is to heat the floor material (such as ceramic tiles or wood flooring) with a heat medium (hot water or high-temperature steam), utilizing thermal radiation and natural convection to raise the indoor temperature. Heating pipes are key facilities in the heating system for transporting heat mediums such as hot water and high-temperature steam, and are widely used in district heating, industrial heating systems, and regional energy supply. Their design must consider thermal efficiency, safety, and durability, while adapting to different environments and engineering requirements. During the installation of heating pipes, clamps are used to fix them to the ground to prevent displacement due to thermal expansion and contraction, water flow impact, or external collisions, ensuring the safe operation of the heating system.

[0003] The clips are installed inside the construction gun, and the gun controls the ejection of the clips. The bottom of the construction gun has an arc-shaped nozzle to accommodate the pipe. In general construction guns, the nozzle is fixedly connected to the gun body. Repeated construction can easily wear down the nozzle, making the arc shape unable to fully accommodate the pipe. This causes the gun body to squeeze the pipe, resulting in deformation or even rupture, leading to leakage of the heat medium. Utility Model Content

[0004] The main purpose of this utility model is to provide a pneumatic underfloor heating nail installation gun to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a pneumatic underfloor heating nailing gun is provided, comprising a gun body and a nail storage part disposed on one side of the gun body.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] This embodiment provides a pneumatic underfloor heating clip installation gun, such as... Figure 1 and 3 As shown, it includes a gun body 1 and a nail storage part 4 located on one side of the gun body 1. The bottom of the gun body 1 is provided with an arc-shaped gun muzzle 5, which is used to hold the underfloor heating pipe. It also includes an extension part 6, which has two parts, located on both sides of the gun muzzle 5 and detachably connected to the gun body 1, for extending the height of the gun muzzle 5.

[0018] The top of the gun body 1 is fixedly equipped with an air inlet 2 and a handle 3. Holding the handle 3 makes it easy to move the construction gun. The inside has an air passage 7 and a channel 10. The channel 10 is located below the air passage 7 and communicates with the muzzle 5. The air passage 7 is connected to the air inlet 2. The air inlet 2 is connected to an air compressor to input compressed air into the air passage 7, pushing the piston 8 downward, thereby causing the ejector pin 9 to extend out of the gun body 1, push out the locking pin, and shoot it into the ground.

[0019] A piston 8 is slidably mounted inside the air passage 7, and a pin 9 is fixedly mounted at the bottom of the piston 8. The pin 9 is slidably mounted inside the channel 10. A return spring 13 is fitted around the outer ring of the pin 9. The return spring 13 is located inside the air passage 7, with its top end fixedly connected to the bottom of the piston 8 and its bottom end fixedly connected to the gun body 1. The diameter of the return spring 13 is slightly smaller than the inner diameter of the air passage 7, allowing the return spring 13 to freely extend and retract within the air passage 7. When the piston 8 moves downward, the return spring 13 contracts. After the pin is driven into the ground, the air compressor no longer supplies compressed gas into the air passage 7, and the return spring 13 rebounds, pushing the piston 8 upward and causing the pin 9 to move upward into the channel 10. After the return spring 13 has fully rebounded, the bottom of the pin 9 is higher than the top of the pin inlet 14, facilitating the pin's entry into the channel 10 from the pin inlet 14. A sealing ring is provided on the outer ring of the piston 8 to increase its sealing with the air passage 7, preventing gas from escaping from the gap between the piston 8 and the air passage 7, thus preventing the piston 8 from moving downward.

[0020] like Figure 4As shown, the gun body 1 has accommodating grooves 11 on both sides of its bottom. The accommodating grooves 11 are located on both sides of the muzzle 5 and are used to accommodate the extension part 6. Each end of the accommodating groove 11 has a retaining groove 12. The size of the accommodating groove 11 is the same as that of the connecting block 61. When the connecting block 61 is fully inserted into the accommodating groove 11, the T-shaped slider 64 aligns with the retaining groove 12, the spring 65 rebounds, and pushes the T-shaped slider 64 into the retaining groove 12, fixing the extension part 6 to the bottom of the gun body 1, increasing the height of the muzzle 5, and preventing the underfloor heating pipes from being squeezed due to wear of the gun body 1.

[0021] The bottom side of the gun body 1 is provided with a nail inlet 14 and a nail storage part 4. The bottom end of the nail storage part 4 is located inside the nail inlet 14 and is used to feed a nail into the gun body 1. The nail inlet 14 is connected to the channel 10. The nail enters the channel 10 from the nail inlet 14 and is pushed out by the ejector pin 9.

[0022] like Figure 2 As shown, the nail storage section 4 includes a lifting rod 41 and an arc-shaped rod 43 fixedly disposed at the bottom of the lifting rod 41. The arc-shaped rod 43 is used to store the nails. A pressure block 42 is slidably sleeved on the arc-shaped rod 43. An arc-shaped groove 44 is provided on the bottom side of the arc-shaped rod 43. An arc-shaped spring 45 is provided in the arc-shaped groove 44. One end of the arc-shaped spring 45 is fixedly connected to the pressure block 42, and the other end is fixedly connected to the gun body 1. When there is no external force, the arc-shaped spring 45 contracts, pulling the pressure block 42 to squeeze it to the outside of the nail inlet 14. When the pressure block 42 is pulled toward the upper end of the arc-shaped rod 43, the arc-shaped spring 45 stretches, locking the nail on the upper side of the arc-shaped rod 43. When the pressure block 42 is released, the arc-shaped spring 45 contracts, pulling the pressure block 42 to slide along the arc-shaped rod 43 toward the nail inlet 14, pushing the foremost nail on the arc-shaped rod 43 from the nail inlet 14 into the channel 10, and placing it directly below the ejector pin 9.

[0023] like Figure 5 As shown, the extension part 6 includes a connecting block 61, a T-slot 62 on the top of the connecting block 61, a stop block 63 fixedly mounted on the middle of the upper surface of the connecting block 61, and an outer cylinder 67 fixedly mounted on the middle of the lower surface. An inner cylinder 68 is threadedly connected to the bottom of the outer cylinder 67. Rotating the inner cylinder 68 causes it to screw into or out of the outer cylinder 67, thus decreasing or increasing the height of the extension part 6. The more severe the wear on the bottom of the gun body 1, the longer the inner cylinder 68 screws out of the outer cylinder 67, thereby compensating for the wear on the gun body 1, increasing the height of the muzzle 5, and preventing the gun body 1 from squeezing the underfloor heating pipes.

[0024] Both ends of the T-slot 62 are slidably connected to T-shaped sliders 64. Several springs 65 are fixedly connected between the T-shaped sliders 64 and the stop block 63. A protrusion 66 is fixedly provided on the lower surface of the T-shaped slider 64, and the protrusion 66 passes through the connecting block 61 and is slidably connected to the connecting block 61. When the springs 65 are in their natural state, they push the T-shaped sliders 64 outward and into the slot 12. If the inner cylinder 68 is severely worn and cannot be unscrewed from the outer cylinder 67, the extension part 6 needs to be removed from the bottom of the gun body 1 and replaced with a new extension part 6. Push the protrusion 66 inward, and the protrusion 66 will drive the T-shaped slider 64 to slide inward and be pulled out of the slot 12. The slot 12 will no longer restrict the T-shaped slider 64, and the extension part 6 can be removed and replaced with a new extension part 6 and placed into the receiving slot 11.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
