Description

Technical Field

[0001] This utility model discloses an axial nail gun. Background Technology

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

[0003] The main working principle of an axial nail gun is to rely on the rapid forward movement of the firing pin to strike the bottom of the nail cartridge, causing the gunpowder inside the cartridge to explode. The high-pressure gas generated by the explosion exerts a huge thrust on the nail at the front end, driving the nail into the base and thus achieving the working task.

[0004] Currently, nail gun products have a protective sleeve around the main sleeve. One function of the protective sleeve is to prevent the main sleeve components from being exposed; another is to restrain the two ends of the reset pin by the inner wall of the protective sleeve, preventing them from falling off. The rear end of the main sleeve is then connected to the handle via threads. Besides facilitating grip, the handle also provides a base for the firing spring. With this structure, the overall length of the machine includes the length of the protective sleeve and the handle, limiting the overall size of the machine and resulting in poor portability.

[0005] Furthermore, in existing nail guns, after firing, the firing pin returns to its original position, allowing explosive residue from the nail tube to enter through the firing pin sleeve. This residue then travels through the inner and outer reset grooves to the circumferential gap between the main sleeve and the protective sleeve. Unable to be discharged, it accumulates and hardens. With increasing usage time, this residue buildup worsens, and if not cleaned regularly, it can cause severe adhesion, rendering the device unusable. Summary of the Invention

[0006] The purpose of this invention is to provide a slag-discharging axial nail gun with an integrated grip to overcome the shortcomings of existing technology.

[0007] The technical solution adopted by this utility model to achieve its purpose is: a slag-discharging axial nail gun with an integrated grip, including a main sleeve and a grip assembly, characterized in that: the grip assembly includes a hollow sleeve, which is sleeved outside the rear of the main sleeve, and a spring seat is connected to the rear end of the main sleeve; the rear end of the spring seat is connected to a fixing nut, and the fixing nut fixes the sleeve.

[0008] There is a slag discharge hole at the bottom of the casing.

[0009] It is equipped with anti-rotation and positioning devices to prevent rotation and position the main sleeve and the casing.

[0010] The anti-rotation device is: the convex ring on the spring seat is provided with an anti-rotation plane or anti-rotation groove, and the sleeve has a corresponding anti-rotation plane or convex key.

[0011] The anti-rotation device is: an anti-rotation plane or anti-rotation groove is provided on the outer wall of the main sleeve, and a corresponding anti-rotation plane or protruding key is provided inside the sleeve.

[0012] The positioning device is as follows: the main sleeve has a positioning ring, and the front end face of the sleeve and the rear end face of the positioning ring are in contact.

[0013] The positioning device is as follows: a limiting step is provided on the inner wall of the sleeve, and the rear end face of the convex ring on the spring seat contacts the limiting step to achieve positioning.

[0014] The positioning device is: a limiting step on the inner wall of the sleeve, and positioning is achieved by contact between the rear end face of the main sleeve and the limiting step.

[0015] The grip assembly includes a grip, which is hollow, and the slag discharge hole is located inside the grip.

[0016] The main casing has a slag discharge and diameter reduction pipe.

[0017] A hook is provided, which can be located at any position on the outer circumference of the sleeve.

[0018] The beneficial effects of this utility model are as follows: by integrating the original protective cover and handle structure, the length of the original protective cover is reduced while retaining the original function, thereby reducing the overall size of the machine. Furthermore, under the existing structural conditions, a slag discharge hole can be added, increasing the overall reliability of the machine and extending the cleaning cycle.

[0036] In the diagram: 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 body, 7 is the slag discharge hole, 8 is the limiting 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 guns. The existing technologies closely related to this embodiment are: 201520748109.3, 201620525943.0, 201620525984.X, 201610383296.9, 201610383308.8, and 201610978775.5, which clearly describe the principle, structure, operation, and components of the axial nail gun. They will not be repeated in this application.

[0039] During assembly, the external thread at the front end of the spring seat 3 is screwed into the internal thread at the rear end of the main sleeve 1. Two anti-rotation planes 11 are machined on the circumference of the convex ring 9 (e.g., Figure 7 As shown), use a wrench to engage the two anti-rotation surfaces 11, and then tighten to secure them. This establishes the connection between the two.

[0040] Then insert the sleeve 4 from the rear end until the limiting step 8 and the rear end face 13 of the protruding ring 9 of the spring seat 3 contact (e.g.) Figure 3 , Figure 8(As shown), complete the positioning. Then screw the internal thread of the fixing nut 5 and the external thread at the rear end of the spring seat 3 together. At this time, the front end ring surface of the fixing nut 5 will press against the rear end ring surface of the sleeve 4, thus securing the sleeve 4 (as shown). Figure 3 (As shown).

[0041] To enhance stability during use, the grip 2 must not rotate freely. This embodiment implements an anti-rotation function, such as... Figure 8 As shown, two anti-rotation planes 12 are provided on the inner wall of the sleeve 4. The parameters of the anti-rotation planes 12 and the previously mentioned anti-rotation planes 11 are adapted. After installation, the anti-rotation planes 12 and 11 are respectively fitted together (e.g., Figure 7 , Figure 8 As shown in the figure, this achieves anti-rotation in the circumferential direction.

[0042] During operation, the residue generated after the nail gun cartridge explodes will be carried by the high-pressure gas from inside the nail tube 30, along the firing pin sleeve 31, the reset inner groove 14, and finally into the main sleeve 1. In this embodiment, an anti-rotation device ensures that the reset inner groove 14 and the reset outer groove 15 always correspond to the slag discharge hole 7. Thus, the residue in the main sleeve 1 will flow along the reset outer groove 15, the slag discharge hole 7, and the hollow handle 6, eventually falling to the outside (e.g., ...). Figure 15 (As shown).

[0043] The function of hook 10 is to allow the user to hang the entire device on their belt for easy carrying and use (e.g.) Figure 8 (As shown). Safety rope hole 40 (as shown) Figure 2 (As shown), it is used to install a safety rope. When using it, put the safety rope around your wrist to prevent accidental falls.

[0044] Example 2:

[0045] The difference between this implementation and Example 1:

[0046] 1. Different positioning methods: In this implementation, a positioning ring 16 is provided on the main sleeve 1. Positioning is achieved by the contact between the front end face 32 of the sleeve 4 and the rear end face 35 of the positioning ring 16 (e.g., Figure 9 (As shown).

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

[0048] In addition, the main sleeve 1 has a slag discharge reducing pipe 18. A circumferential gap 33 is formed between the outer wall of the slag discharge reducing pipe 18 and the sleeve 4. This circumferential gap 33 has two advantages: first, it avoids the adhesion of residue; 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 still fall smoothly from the circumferential gap 33 into the slag discharge hole 7-the body 6-the outside under the action of gravity (e.g., ...). Figure 11 (As shown).

[0049] Example 3:

[0050] Compared with Example 1, this implementation differs in its positioning method: the protruding ring 9 and the anti-rotation plane 11 on the spring seat 3 are eliminated, and the rear end face 34 of the main sleeve 1 directly contacts the limiting step 8 to achieve positioning (e.g., Figure 12 (As shown).

[0051] Example 4:

[0052] The difference between this embodiment and embodiment 1 is that the anti-rotation method is changed from a planar contact type to a keyway type: the anti-rotation planes 11 and 12 are eliminated, 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 inside the sleeve 4. During assembly, the convex key 21 is inserted into the anti-rotation groove 20 to achieve the anti-rotation function (e.g., Figure 13 (As shown).

[0053] Example 5:

[0054] The difference between this embodiment and embodiment 2 is that the anti-rotation method is changed from a planar contact type to a keyway type: the anti-rotation planes 17 and 12 are eliminated, and an anti-rotation groove 22 is provided on the outer wall of the main sleeve 1. A protruding key 21 is provided inside the sleeve 4. During assembly, the protruding key 21 is inserted into the anti-rotation groove 22 to achieve the anti-rotation function (e.g., Figure 14 (As shown).
