Description

Technical Field

[0001] The invention discloses an axial nail shooter. Background Art

[0002] The axial nail gun technology currently used is mature and has a wide range of applications.

[0003] The main working principle of the axial nail gun is to rely on the firing pin to move forward quickly to hit the bottom of the nail bullet, causing the gunpowder inside the nail bullet to explode. The high-pressure gas generated by the explosion produces a huge thrust on the nail at the front end, driving the nail into the matrix, thereby completing the working task.

[0004] Current nail guns feature a protective cover over the main housing. This protects the housing from being exposed and prevents the reset pin from falling out. The rear end of the housing is threadedly connected to the handle, which not only provides a convenient grip but also provides a base for the trigger spring. With this structure, the entire device is comprised of both the protective cover and the handle, making it difficult to create a compact design and impairing portability.

[0005] Furthermore, after firing, the firing pin of existing nail guns resets backwards, causing the explosive debris in the nail barrel to enter through the firing pin sleeve and then pass through the reset inner groove and reset outer groove to reach the circumferential gap between the main sleeve and the protective sleeve. Since there is no way to drain it away, it will accumulate and harden. As the use of the nail gun increases, the debris accumulates more and more. If it is not cleaned regularly, it will cause serious adhesion and make it impossible to use normally. Summary of the Invention

[0006] The purpose of the present invention is to provide a slag-discharging axial nail shooter with an integrated handle to make up for the shortcomings of the prior art.

[0007] The technical solution adopted by the present invention to achieve the purpose is: a slag-discharging axial nail gun with an integrated grip, including a main sleeve and a grip assembly, and its characteristics are: the grip assembly includes a hollow sleeve, the sleeve is sleeved outside the rear part of the main sleeve, and the rear end of the main sleeve is connected to a spring seat; the rear end of the spring seat is connected to a fixing nut, and the fixing nut fixes the sleeve.

[0036] In the figure: 1 is the main sleeve, 2 is the grip, 3 is the spring seat, 4 is the sleeve, 5 is the fixing nut, 6 is the handle, 7 is the slag discharge hole, 8 is the limit step, 9 is the convex ring, 10 is the hook, and 50 is the hammer.

[0037] Example 1:

[0038] The applicant has been committed to the research and development of axial nail shooters. The prior art that is closely related to this embodiment includes: 201520748109.3, 201620525943.0, 201620525984.X, 201610383296.9, 201610383308.8, and 201610978775.5, which fully describe the principle, structure, operation, and components of the axial nail shooter. These are not further described in this application.

[0039] During assembly, screw the external thread at the front end of the spring seat 3 into the internal thread at the rear end of the main sleeve 1, and two anti-rotation flat surfaces 11 (such as Figure 7 As shown in FIG, use a wrench to engage the two anti-rotation planes 11 and then tighten them to achieve fastening.

[0040] Then insert the sleeve 4 from the rear end until the limiting step 8 contacts the rear end surface 13 of the convex ring 9 of the spring seat 3 (as shown in FIG. Figure 3 、 Figure 8Then screw the internal thread of the fixing nut 5 to the external thread at the rear end of the spring seat 3. At this time, the front annular surface of the fixing nut 5 presses the rear annular surface of the sleeve 4, which can tighten the sleeve 4 (as shown). Figure 3 shown).

[0041] In order to enhance stability during use, the handle 2 is required not to rotate arbitrarily. This embodiment implements an anti-rotation function. Figure 8 As shown, two anti-rotation planes 12 are provided on the inner wall of the sleeve 4. The anti-rotation planes 12 and the anti-rotation planes 11 described above are adapted to each other in parameters. After being installed in place, the anti-rotation planes 12 and the anti-rotation planes 11 are respectively fitted (as shown in FIG. Figure 7 、 Figure 8 As shown), thereby achieving anti-rotation in the circumferential direction.

[0042] When the whole machine is in use, the residue generated after the nail bullet explodes will be carried by the high-pressure gas from the inside of the nail tube 30 along the inside of the firing pin sleeve 31, the reset inner groove 14, and finally to the main sleeve 1. In this embodiment, the anti-rotation device is used to make the reset inner groove 14 and the reset outer groove 15 always correspond to the slag discharge hole 7. In this way, the residue in the main sleeve 1 will follow the reset outer groove 15, the slag discharge hole 7, and the hollow handle 6, and finally fall to the outside (such as Figure 15 shown).

[0043] The function of the hook 10 is that the user can hang the whole device on the belt for easy carrying (such as Figure 8 Safety rope hole 40 (as shown). Figure 2 It is used to install the safety rope. When using it, put the safety rope around your wrist to prevent it from falling accidentally.

[0044] Example 2:

[0045] The difference between this embodiment and Example 1 is:

[0046] 1. Different positioning methods: In this embodiment, there is a positioning ring 16 on the main sleeve 1, and the front end face 32 of the sleeve 4 and the rear end face 35 of the positioning ring 16 are in contact to achieve positioning (such as Figure 9 shown).

[0047] 2. Different anti-rotation methods: The two anti-rotation planes 11 on the convex ring 9 are cancelled, and two anti-rotation planes 17 are processed on the outer wall of the rear end of the main sleeve 1. The anti-rotation planes 17 and the anti-rotation planes 12 cooperate to achieve anti-rotation (such as Figure 10 shown).

[0048] In addition, the main sleeve 1 is provided with a slag discharge reduction pipe 18, and a circumferential gap 33 is formed between the outer wall of the slag discharge reduction pipe 18 and the sleeve 4. This circumferential gap 33 has two advantages: first, it avoids the adhesion phenomenon formed by the formation of residues. Second, even if the reset inner groove 14 and the reset outer groove 15 do not correspond to the slag discharge hole 7, the residue will fall smoothly from the circumferential gap 33 to the slag discharge hole 7-body 6-external environment (such as the slag discharge hole 7-body 6-external environment) under the action of gravity. Figure 11 shown).

[0049] Example 3:

[0050] Compared with Example 1, this embodiment has a different positioning method: the convex ring 9 and the anti-rotation plane 11 on the spring seat 3 are cancelled, and the rear end surface 34 of the main sleeve 1 directly contacts the limiting step 8 to achieve positioning (such as Figure 12 shown).

[0051] Example 4:

[0052] The difference between this embodiment and embodiment 1 is that the anti-rotation method is changed from a plane contact type to a key groove type: the anti-rotation planes 11 and 12 are cancelled, and an anti-rotation groove 20 is provided on the convex ring 9 of the spring seat 3, and a convex key 21 is provided in the sleeve 4. When assembling, the convex key 21 is inserted into the anti-rotation groove 20 to realize the anti-rotation function (such as Figure 13 shown).

[0053] Example 5:

[0054] The difference between this embodiment and embodiment 2 is that the anti-rotation method is changed from a plane contact type to a key groove type: the anti-rotation planes 17 and 12 are cancelled, and an anti-rotation groove 22 is provided on the outer wall of the main sleeve 1, and a convex key 21 is provided in the sleeve 4. When assembled, the convex key 21 is inserted into the anti-rotation groove 22 to realize the anti-rotation function (such as Figure 14 shown).
