Description

Technical Field

[0001] The utility model relates to the technical field of nail shooters, in particular to a firing mechanism of a nail shooter. Background Art

[0002] A nail gun, also known as a nail gun, is often called a nail gun because of its similar appearance and working principle to a pistol. It is a fastening tool that uses blank cartridges, gas, or compressed air as power to drive nails into structures.

[0003] The existing nail shooters all have springs inside the inner hole of the firing cap, which can easily cause many problems during long-term use. For example, the spring installed in the inner hole of the firing cap will limit the outer diameter and wire diameter of the spring. If the spring is too thin, it will collapse severely after about 1,000 firings during use, and may even fail to fire. The firing cap is installed from top to bottom. During the disassembly and cleaning process, it is easy for the firing cap to be instantly ejected by the compression force of the spring. The firing cap is small in size and most of the time it cannot be found after it is ejected on a messy construction site. The firing cap is installed on the firing pin seat. The bottom of the firing pin seat is sealed for installing the spring. During use, the nail shooter will produce a lot of residue, which will be sprayed into the gap between the firing cap and the firing pin seat. After the residue accumulates at the bottom of the spring, it will get stuck and fail to fire. Utility Model Content

[0004] The utility model provides a firing mechanism of a nail shooter, which can prevent the firing cap from popping out of the firing pin seat to avoid loss, and does not limit the size of the spring. The thickening and enlargement of the spring solves the problem that the spring is small and the elasticity is insufficient to cause collapse due to repeated use, and also avoids the problem of dust accumulation and jamming.

[0005] In order to solve the above technical problems, the present invention provides a nail shooter firing mechanism, comprising:

[0006] The firing pin seat is provided with a firing cavity through it, and one end of the top of the firing cavity is connected to an ejection outlet, and the diameter of the ejection outlet is smaller than the diameter of the firing cavity;

[0007] The firing cap comprises a movable block and a cap head, wherein the cap head is provided on the top of the movable block, the movable block is slidably connected to the inner wall of the ejection port, and an extension block is provided on the bottom of the movable block;

[0008] A spring is arranged around the extension block.

[0009] As a preferred embodiment of the above technical solution, a limiting groove is provided around the interior of the firing chamber, and a firing cap is filled between the ejection outlet and the limiting groove.

[0010] As a preferred embodiment of the above technical solution, a positioning ring is provided around the outer side of the extension block and the positioning ring is arranged on the bottom surface of the movable block.

[0011] As a preferred embodiment of the above technical solution, one end of the top of the spring is connected to the bottom surface of the positioning ring.

[0012] As a preferred embodiment of the above technical solution, the positioning ring is slidably connected to the inner wall of the launching cavity, and the diameter of the limiting groove is greater than the diameter of the positioning ring.

[0013] As a preferred embodiment of the above technical solution, a clamping slot is provided inside the limiting slot, a clamping ring is movably provided inside the clamping slot, and a clamping block is provided at the end of the clamping ring, and the clamping block matches the clamping slot.

[0014] The utility model provides a firing mechanism of a nail shooter, which comprises a firing chamber, an ejection outlet, a firing cap and a spring. The spring is arranged around the outside of the extension block of the firing cap and is installed by the bottom of the firing pin seat. During the disassembly, cleaning and maintenance process, the firing cap will not pop out of the firing pin seat, thereby avoiding the situation that the firing cap is lost after it is ejected. At the same time, the spring is no longer installed inside the firing cap, and there is no need to limit the size of the spring. The thickening and enlargement of the spring solves the problem that the spring is small, the elasticity is insufficient, and the collapse caused by the use of about 10 times is solved. Moreover, the entire firing cap is installed from bottom to top, and the bottom hole is empty, thereby avoiding the situation that dust is blocked and the firing cap is stuck and cannot be fired. The entire firing mechanism can achieve that the firing cap will not pop out of the firing pin seat to avoid loss, and there is no need to limit the size of the spring. The thickening and enlargement of the spring solves the problem that the spring is small, the elasticity is insufficient, and the collapse caused by repeated use is avoided, and dust accumulation and jamming are also avoided.

[0021] See also Figure 1-3 The present invention provides a firing mechanism for a nail shooter, comprising:

[0022] The firing pin seat 1 is provided with a firing chamber 2, and one end of the top of the firing chamber 2 is connected to a firing outlet 21, and the diameter of the firing outlet 21 is smaller than the diameter of the firing chamber 2;

[0023] The firing cap 3 includes a movable block 31 and a cap head 32. The cap head 32 is provided on the top of the movable block 31. The movable block 31 is slidably connected to the inner wall of the ejection port 21. The bottom of the movable block 31 is provided with an extension block 34.

[0024] The spring 4 is arranged around the extension block 34 .

[0025] The present embodiment provides a firing mechanism of a nail shooter, which has a firing chamber 2, an ejection outlet 21, a firing cap 3 and a spring 4. The spring 4 is arranged around the outside of the extension block 34 of the firing cap 4 and is installed from the bottom of the firing pin seat 1. During the disassembly, cleaning and maintenance process, the firing cap 3 will not pop out of the firing pin seat 1, thereby avoiding the situation where the firing cap 3 is lost after it is ejected. At the same time, the spring 4 is no longer installed inside the firing cap 3, and there is no need to limit the size of the spring. The thickening and enlargement of the spring solves the problem of the previous spring being small and the elasticity being insufficient, which causes a collapse after about 1,000 uses. Moreover, the entire firing cap 3 is installed from bottom to top, and the bottom hole is empty, thereby avoiding the situation where dust clogs and jams the firing cap 3 and makes it unable to fire. The entire firing mechanism can achieve the situation where the firing cap 3 will not pop out of the firing pin seat 1 to avoid loss. There is no need to limit the size of the spring. The thickening and enlargement of the spring solves the problem of the previous spring being small and the elasticity being insufficient, which causes a collapse after repeated uses, and also avoids the situation where dust accumulates and jams.

[0026] In a further possible implementation of this embodiment, a limiting groove 22 is provided around the interior of the firing chamber 2 , and a firing cap 3 is filled between the ejection outlet 21 and the limiting groove 22 .

[0030] In a further embodiment of the present invention, one end of the top of the spring 4 is connected to the bottom surface of the positioning ring 33 .

[0031] The spring 4 in this embodiment is no longer installed inside the firing cap 3, and there is no need to limit the size of the spring. The thickening and enlargement of the spring solves the problem of the previous spring being small, the elasticity being insufficient, and the collapse occurring after about 1,000 uses.

[0032] In a further possible implementation of this embodiment, the positioning ring 33 is slidably connected to the inner wall of the launching cavity 2 , and the diameter of the limiting groove 22 is greater than the diameter of the positioning ring 33 .

[0033] The limiting groove 22 in this embodiment has a larger diameter to facilitate overall disassembly and installation.
