Description

Technical Field

[0001] The utility model relates to a nail gun, belonging to the technical field of power tools. Background Art

[0002] Nail guns, owing to their convenience, efficiency, and safety, are widely used in modern production and daily life. When a nail gun is in operation, a compression or tension spring pushes the nail into a slot in the gun cap, where it is then ejected from the gun nozzle by a firing pin. Depending on the specific application, the operator may need to change nails of different specifications, which requires changing the corresponding gun nozzle to ensure that the nail is accurately driven into the target material.

[0003] However, existing nail guns have limitations when it comes to nozzle replacement. For example, patent publication number CN216229193U describes a quick-change nozzle device for a pneumatic nail gun. While this device simplifies nozzle replacement, its complex internal structure leads to high production costs and makes repairs difficult in the event of a mechanical failure. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems existing in the prior art and provide a steel nail gun with a quick-detachable gun nozzle, which has a simple structure and reliable operation.

[0005] To solve the above technical problems, the utility model provides a steel nail gun with a quick-detachable gun nozzle, comprising: a nailing seat mounted at the front end of the steel nail gun and a gun nozzle inserted into the front end of the nailing seat, wherein a nail magazine is further inserted into the bottom of the nailing seat, and the utility model is characterized in that: the rear end of the gun nozzle is a gun nozzle plug end, the gun nozzle plug end is columnar, and the rear end outer wall is provided with a gun nozzle boss;

[0006] A gun nozzle socket is provided at the front end of the nailing seat, an annular groove is provided on the rear side of the gun nozzle socket, and a boss slot is provided along the inner wall of the gun nozzle socket that penetrates axially. The gun nozzle plug-in end is inserted into the gun nozzle socket, and the gun nozzle boss passes through the boss slot and is embedded in the annular groove after rotating with the gun nozzle.

[0007] Furthermore, a gun nozzle positioning plane is formed by cutting on the rear end circumference of the gun nozzle plug-in end, and a right-angle limiting step is provided on the front side of the plug-in end of the nail magazine, and the bottom of the right-angle limiting step rests on the bottom of the gun nozzle positioning plane.

[0008] Furthermore, the gun nozzle boss abuts against the front step of the annular groove, and the rear side of the gun nozzle plug-in end abuts against the rear vertical wall of the right-angle limiting step.

[0009] Furthermore, two gun nozzle bosses are symmetrically provided on the outer wall of the gun nozzle plug-in end.

[0010] Furthermore, the nozzle positioning plane is located between the two nozzle bosses.

[0011] Furthermore, the phase difference between the positioning plane of the gun nozzle and the gun nozzle boss is 90°.

[0012] Compared with the existing technology, the present invention has the following advantages: 1. The present invention only requires the nozzle and its carrier (such as the nailing base and nail magazine assembly) to achieve disassembly and assembly, without the need for additional structural parts. This not only makes the overall structure more simple and compact, reducing the volume, but also significantly reduces manufacturing costs and improves economic efficiency;

[0013] 2. The nozzle can be quickly disassembled and assembled without any tools, greatly facilitating daily use and maintenance. This design not only reduces the chance of mechanical failure, but even if a problem occurs, users can easily disassemble the nozzle for inspection or replacement, avoiding the possibility of the nozzle getting stuck due to complex structure.

[0014] 3. The utility model reduces maintenance time and cost, and increases the practicality and durability of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the following description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figures 1 to 4 As shown, the utility model is a steel nail gun with a quick-detachable gun nozzle 2, comprising: a nailing seat 1 installed at the front end of the steel nail gun and a gun nozzle 2 inserted into the front end of the nailing seat 1, a nail magazine 3 is also inserted into the bottom of the nailing seat 1, and the rear end of the gun nozzle 2 is a gun nozzle plug end, which is cylindrical and has a gun nozzle boss 2a on the outer wall of the rear end;

[0029] The front end of the nailing station 1 is provided with a nozzle socket 1a. An annular groove 1c is located behind this socket 1a. A boss slot 1b extends axially through the inner wall of this socket 1a. The nozzle plug-in end is inserted into the socket 1a. A nozzle boss 2a passes through the boss slot 1b and rotates with the nozzle 2 to engage in the annular groove 1c. Two nozzle bosses 2a are symmetrically located on the outer wall of the nozzle 2. After the nozzle 2 is inserted into the socket 1a, it is rotated a certain angle so that the nozzle bosses 2a engage in the annular groove 1c.

[0030] A nozzle positioning surface 2b is cut into the rear circumference of the insertion end of the nozzle 2. A right-angled stopper step 3b is provided in front of the insertion end 3a of the magazine 3. The bottom of the right-angled stopper step 3b abuts below the nozzle positioning surface 2b. The nozzle positioning surface 2b is located between the two nozzle bosses 2a, and the positioning surface of the nozzle 2 is 90° out of phase with the nozzle bosses 2a.

[0031] The gun nozzle boss 2a abuts against the front step of the annular groove 1c, and the rear side of the gun nozzle 2 abuts against the rear vertical wall of the right-angle limit step 3b, preventing the gun nozzle 2 from falling out of the nailing seat 1 due to rotation.

[0032] The utility model only requires the nozzle 2, the nail base 1 and the nail magazine to achieve the disassembly and assembly function, without the need for additional structural parts. The structure is more simple and compact, reducing the volume, while also significantly reducing the manufacturing cost and improving economic efficiency. At the same time, the utility model supports rapid disassembly and assembly without any tools, greatly facilitating the user's daily use and maintenance.

[0033] The above description is only a preferred embodiment of the present invention, which shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It does not limit the scope of patent protection of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. In addition to the above embodiments, the present invention may have other implementation methods without departing from the spirit and scope of the present invention. The present invention may also have various changes and improvements. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the attached claims and their equivalents. The technical features not described in the present invention can be achieved by or using existing technologies, and will not be described here.
