Description

TECHNICAL FIELD

[0001] The utility model relates to a nail gun nail box mechanism, concretely is a split combination formula lower shell structure of nail gun nail box mechanism. BACKGROUND

[0002] The nail box mechanism of nail gun (pneumatic or electric) is generally composed of upper shell, lower shell and nail clamp with nail storage and nail feeding functions, the combination surface of the lower shell and the upper shell is provided with a nailing groove, and the lower shell is provided with a nail outlet at the middle part of the nailing groove, such as the gun needle driving mechanism of the electric nail gun disclosed in patent CN202320218575.5.

[0003] The upper part of the front part of the lower shell is provided with two spaced connection hooks, and the upper part of the tail part of the lower shell is provided with two spaced mounting seats, the mounting seat is hinged with the rear end of the upper shell, and the middle part of the upper shell is detachably connected with the connection hooks through a buckle plate and a metal buckle ring.

[0004] In the above structure, the lower shell and the connection hooks thereon are an integral structure, which greatly affects the machining precision of the lower shell. Because the connection hooks protrude from the upper surface of the lower shell, the processing of the upper surface of the lower shell cannot be operated by a grinding machine, and only precision milling can be used for processing. However, due to the hardness of the milling cutter itself, it cannot be applied to high-hardness materials after quenching. Therefore, during the entire machining process of the lower shell, the surface is machined in multiple longitudinal and transverse directions, and then quenched. However, the quenching process causes slight bending deformation of the surface of the lower shell, which affects the surface precision of the lower shell, makes the fit of the lower shell and the upper shell cannot be guaranteed, and finally causes the nail gun to be stuck. UTILITY MODEL CONTENTS

[0005] In view of the above problems, the utility model designs a split combination formula lower shell structure of nail gun nail box mechanism, the connection hooks on the upper surface of the lower shell adopt a split combination structure, so that the lower shell can be quenched and then surface finished, which can effectively guarantee the fit of the lower shell and the upper shell, and effectively reduce the phenomenon of the nail gun being stuck.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A split combination formula lower shell structure of nail gun nail box mechanism, comprising a lower shell body, characterized in that: the upper surface of the lower shell body is a horizontal fitting plane, and the front side of the lower shell body is provided with two spaced mounting holes, and each mounting hole is provided with a connection hook in interference fit.

[0008] More specifically, the material hardness of the connecting clasp is lower than the material hardness of the lower shell body.

[0009] More specifically, the bottom end of each connecting clasp is provided with a stop protrusion.

[0010] More specifically, the lower shell body is provided with a nail outlet in the middle.

[0011] More specifically, the rear side of the lower shell body is provided with two spaced connecting holes, and a connecting seat is installed in the connecting hole, and the upper side of the connecting seat is movably connected with the tail of the upper shell.

[0012] More specifically, the inner side of each connecting clasp is provided with a guide slope.

[0013] The lower shell of the nail box mechanism designed in the utility model is composed of a split lower shell body and a connecting clasp, and the two are independently machined and assembled later. The surface of the lower shell body is a complete plane without protrusions, and the surface is precisely machined after quenching to increase the hardness, and then the lower shell body is assembled with the connecting clasp to obtain a complete product. The precision of the surface of the lower shell can be effectively ensured, so that the lower shell and the upper shell are closely attached, and the quality of the entire nail gun is improved.

DETAILED DESCRIPTION

[0018] As Figs. 1-3 shown, a split combined lower shell structure of a nail gun nail box mechanism includes a lower shell body 1, the upper surface of the lower shell body 1 is a horizontal plane of close 11, a nail outlet 12 is arranged in the middle, and the front side of the lower shell body 1 is provided with two spaced mounting holes 13, and each mounting hole is provided with a connecting clasp 2.

[0019] For the convenience of installation, the bottom end of each connecting clasp 2 is provided with a stop protrusion 21, and in assembly, the connecting clasp 2 is passed through the mounting hole 13 from bottom to top, and the process is continued until the stop protrusion 21 abuts against the bottom of the lower shell body 1, at which time the installation of the connecting clasp 2 on the lower shell body 1 is completed.

[0020] The lower shell body 1 and the connecting clasp 2 constituting the lower shell are in a split combination structure, and are independently machined respectively, which makes the surface of the lower shell body 1 free of protrusions before assembly, that is, a complete plane, and in machining, the surface can be first quenched to increase the hardness and then placed in a grinding machine for surface finishing, and finally assembled with the connecting clasp 2 to obtain a complete product. The split combination structure can effectively ensure the precision of the surface of the lower shell and improve the fit of the lower shell and the upper shell 3.

[0021] Here, considering that the interference fit of the connecting clasp 2 and the mounting hole 13 will inevitably cause a certain material deformation, the material hardness of the connecting clasp 2 is lower than that of the lower shell body 1, so that even if the interference assembly of the two is deformed, the deformation amount is mainly absorbed by the connecting clasp 2, and the lower shell body 1 will not be substantially damaged, thereby ensuring the precision of the lower shell body 1, especially the surface thereof.

[0022] The rear side of the lower shell body 1 is provided with two spaced-apart connecting holes 14, and a connecting seat 4 is installed in the connecting hole 14, the upper side of the connecting seat 4 is movably hinged to the tail of the upper shell 3, the middle part of the upper shell 3 is provided with a fixed seat 31, the fixed seat 31 is hinged to the front end of a buckle plate 5, the middle part of the buckle plate 5 is hinged to a metal buckle ring 6, and the metal buckle ring 6 is separable or connectable with the connecting clasp 2. The inner side of each connecting clasp 2 is provided with a guide slope 22, and the guide slopes 22 of the two connecting clasps 2 combine to form a guide opening that is large at the top and small at the bottom, which can ensure the centering when the upper shell 3 is pressed downward relative to the lower shell, thereby improving the fit after assembly and avoiding the phenomenon of nail gun clamping.

[0023] For the convenience of installation of the connecting seat 4 on the connecting hole 14, the connecting hole 14 is provided with a positioning groove 141 at the mouth thereof, and the connecting seat 4 is provided with a positioning protrusion 41, and in assembly, the positioning protrusion 41 is engaged with the positioning groove 141 in position.

[0024] The above is only a preferred embodiment of the present application, and does not limit the application in any form, and any simple modification, equivalent change or modification made according to the technical principle of the present application to the above embodiment still belongs to the scope of the technical scheme of the present application.
