TECHNICAL FIELD
[0001] The utility model relates to lithium electric nail gun technical field especially, it is a kind of lithium electric nail gun with closed tail cover. BACKGROUND
[0002] Lithium electric nail gun as the new member of nail gun, without auxiliary equipment such as air compressor, compared with pneumatic nail gun, lithium electric nail gun's complete set of equipment is much lighter, so it is much favored by users, such as often used in cement surface operation.
[0003] Before operation, because of the special texture of cement surface, generally need to keep the whole lithium electric nail gun with the vertical perpendicular state of cement surface, to avoid nail gun to lift off cement surface when shooting, so generally applicable to the lithium electric nail gun of cement surface operation is provided with support base.Before shooting operation on cement surface, the operator first presses the support base on the cement surface, at this time the nail gun is supported, and the operator starts to adjust the vertical perpendicularity of the nail gun and the cement surface.
[0004] Although the above-mentioned manner is helpful to the adjustment of the perpendicularity between the nail gun and the cement surface, in actual use, because most nail guns consider the problem of compact structure, most of the support bases are designed as cylindrical structures with small size, mainly relying on the narrow bottom surface of the cylindrical structure to press the cement surface, which will result in too small pressing area between the nail gun and the cement surface, and the supporting force of the whole nail gun is weak, which is not conducive to the rapid and convenient adjustment of the vertical perpendicularity of the whole nail gun and the cement surface.
[0005] Secondly, most of the support bases are separately installed at the bottom of the nail loading box, so that the installation of the support base is needed after the installation of the closed tail cover of the nail loading box. Even if some are designed to be directly installed on the closed tail cover, it can be slightly more convenient, that is, the support base can be installed on the closed tail cover first, and then the installed closed tail cover is matched to the nail loading box, without the installation of the support base at the bottom of the nail loading box, but the installation of the support base cannot be avoided.
[0006] And most of the closed tail covers are basically connected with the side of the nail gun shell. After connection, there is a laterally protruding connection structure, which will be pressed between the shell side and the worker's body when the nail gun is hung on the worker's belt through the hook.

[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0025] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.
[0026] The lithium electric nail gun of the present application mainly optimizes and improves the closed tail cover, and constructs an integrated structure of the closed tail cover. The closed tail cover has a support body extending downward along the bottom thereof, so that the support body can be constructed to have a larger support bottom surface to solve the problem of small support area which is not conducive to adjusting the verticality of the nail gun. Meanwhile, the nail gun of the present application also has a top connecting end, and an installation wall body is arranged at the outer end of the motor shell and the battery shell to install the top connecting end, thereby avoiding installing the top connecting end on the side of the nail gun shell. In this way, when the nail gun is hung, since there is no installation protruding structure on the side, the comfort of hanging is not affected.
[0027] Embodiment One
[0028] Specifically, the top connecting end is arranged on the installation wall body, and the installation wall body is arranged on the outer end of the motor shell and the battery shell. Figures 1-7The embodiment is described in detail, in which a lithium electric nail gun is provided, which includes a shell 100, the shell 100 including a gun body shell 101, a battery shell 102 connected to the front end of the gun body shell 101, a handle shell 103 connected to the middle of the gun body shell 101, and a motor shell 104 connecting the battery shell 102 and the handle shell 103. In this embodiment, the shell 100 is composed of two shell bodies, i.e. shell body one and shell body two, which are basically symmetrical and slightly different in local design. The gun body shell 101, the battery shell 102, the handle shell 103, and the motor shell 104 that constitute the shell 100 are also composed of two shell bodies, i.e. the gun body shell 101, the battery shell 102, the handle shell 103, and the motor shell 104 each have shell body one and shell body two. It should be noted that the two shell bodies that are used to assemble the shell 100, i.e. shell body one and shell body two, are of one-piece structure, so the two shell bodies that constitute the gun body shell 101, i.e. shell body one and shell body two, are also of one-piece structure, and the battery shell 102, the handle shell 103, and the motor shell 104 are similar. By such arrangement, the shell body one and the shell body two of the gun body shell 101, the battery shell 102, the handle shell 103, and the motor shell 104 can be avoided to be formed separately.
[0029] The lithium electric nail gun also includes a nail magazine, the tail of which is provided with a closing tail cover 300, which continues to extend downward along the bottom to form a support body 1 integrally formed with the closing tail cover 300, which has a flat bottom surface 2 for supporting. The support body 1 is formed by continuing to extend downward along the bottom of the closing tail cover 300, so that the bottom of the closing tail cover 300 generally has a certain length and width, which can naturally expand into a support body 1 with a certain length and width after continuing to extend along the bottom. Thus, the bottom of the support body 1 naturally has a larger bottom surface 2 for supporting.
[0030] For the closed tail cover 300, in addition to setting the integral support body 1, the top of the closed tail cover 300 is also configured with a top connecting end 3 integrally formed with the closed tail cover 300, and the outer end of the motor housing 104 connected with the battery housing 102 is configured with a mounting wall body 4 after being inwardly recessed, and the top connecting end 3 is attached to the mounting wall body 4. The connecting end 3 is mounted at the outer end of the motor housing 104 connected with the battery housing 102, not mounted at the side of the shell 100, that is, not mounted at the side of the motor housing 104 connected with the battery housing 102, so that there is no outward protruding mounting structure at the side, so as not to form a resting feeling on the body after the nail gun is hung on the worker's belt. And the mounting wall body 4 is configured after the outer end of the motor housing 104 connected with the battery housing 102 is inwardly recessed, so that a space is formed by inwardly recessing the outer end, which can basically accommodate the top of the top connecting end 3 in the space for assembly connection, and the top of the top connecting end 3 after assembly connection also does not protrude outwardly relative to the outer end, which can effectively ensure the compactness of the overall structure of the nail gun.
[0031] For how the top connecting end 3 is assembled on the mounting wall body 4, there are many realizable styles. In the embodiment, the following technical means are mainly used, specifically, the outer side wall of the mounting wall body 4 is provided with a clamping groove 6, the top connecting end 3 is clamped in the clamping groove 6, the inner side wall of the mounting wall body 4 is provided with a containing chamber 7, the containing chamber 7 is fixed with a mounting plate 8, the frame of the containing chamber 7 further extends a pressing seat 9 for pressing the mounting plate 8 in the containing chamber, and the top connecting end 3 is further provided with a pressing rod 10 screwed with the mounting plate 8 at the end, and the head of the pressing rod 10 exposed from the top connecting end 3 is provided with an operation knob 11. After the above components are arranged, the top connecting end 3 is attached to the mounting plate 8 by the pressing rod 10, and is connected by threaded connection, which can be easily disassembled. The mounting plate 8 can be fixed under the action of the containing chamber 7 and the pressing seat 9, and the top connecting end 3 is specially clamped in the clamping groove 6, which is further clamped and mounted after disassembly connection, so that the stable installation of the top connecting end 3 is further promoted.
[0032] In view of the convenience of inserting the mounting plate 8 for fixation, the motor housing 104 and the battery housing 102 are integrally formed in this embodiment, and the integral structure is formed by splicing the first housing 105 and the second housing 106. The containing chamber 7 and the pressing seat 9 are arranged on the first housing 105, and the abutting frame 12 is arranged on the inner side wall of the second housing 106 at the mounting wall 4. The edge of the mounting plate 8 extending out of the containing chamber 7 abuts against the abutting frame 12. Through such a clever design, the mounting plate 8 can be inserted from the side of the containing chamber 7 of the first housing 105, and then the second housing 106 is spliced, and the edge of the mounting plate 8 extending out is naturally matched and abuts against the abutting frame 12, thereby achieving the overall fixation and installation of the mounting plate 8. It should be noted that because the mounting plate 8 is screwed with the pressing rod 10, it needs to have good fixation effect itself, and therefore the above structure is optimized in this embodiment.
[0033] In this embodiment, in view of the fact that the existing nail gun needs to push the nail pusher 400 to the nail inlet 301 at the rear of the closing tail cover 300 to put the nails in the row for nail insertion, the efficiency of nail insertion is relatively affected when fast nailing is needed. Therefore, the closing tail cover 300 is also specially provided with a functional part in this embodiment. Specifically, the back of the closing tail cover 300 is provided with an elastic limiting structure, which includes a limiting piece 13 and a spring 14. The limiting piece 13 includes a driving part 131 and a limiting part 132 integrally connected to one end of the driving part 131. The driving part 131 is rotatably mounted on the back of the closing tail cover 300 through a mounting shaft 15, so that the driving part 131 can rotate by a suitable angle around the mounting shaft 15 after being forced. The closing tail cover 300 is also provided with a first through hole 16, and the nail magazine is provided with a second through hole 17 at the first through hole 16. The limiting part 132 integrally forms a nail limiting block 18 at the end. The other end of the driving part 131 is connected to the back of the closing tail cover 300 through the spring 14. One end of the spring 14 acts on the back of the closing tail cover 300, and the other end of the spring 14 acts on the driving part 131. The nail limiting block 18 has a guide inclined wall 19 with an inclination direction consistent with the advancing direction of the nails. The nail limiting block 18 also has a limiting stop wall 20 for preventing the nails from retreating after sliding through the guide inclined wall 19. The nail limiting block 18 protrudes out of the second through hole 17 through the first through hole 16 under the action of the spring 14 after the nail slides through the guide inclined wall 19, and the limiting stop wall 20 limits the retreat of the nails at this time.
[0034] In actual use, the row of nails can be first sent into the nail inlet 301 and pushed forward through the guide inclined wall 19. At this time, the guide inclined wall 19 is submerged into the second through hole 17 under the pressure of the row of nails and the row of nail limiting blocks 18. After the row of nails slides through the guide inclined wall 19, the row of nail limiting blocks 18 continue to extend out of the second through hole 17 under the rebounding action of the spring 14. At this time, the nail at the end of the row of nails is blocked by the limiting wall 20, thereby avoiding the retreat of the row of nails. At this time, the nail pusher 400 is pushed to the position of the row of nails, and the row of nails can be sent into the nail pusher 400. In this process, the nail pusher 400 does not need to be pushed back to the bottom, the pushing path is shortened, and the efficiency of nailing is improved.
[0035] In this embodiment, the installation structure of the spring 14 is also specially set. The back of the closed tail cover 300 and the driving part 131 are respectively provided with mounting protruding columns 21, and the two ends of the spring 14 are respectively clamped on the mounting protruding columns 21. After the mounting protruding columns 21 are added, the two ends of the spring 14 are tightly sleeved on the corresponding mounting protruding columns 21, so that the stable installation of the spring 14 is realized, and the spring 14 is prevented from bouncing out.
[0036] For the specific structure of the limiting part 13, various structures can be realized. In this embodiment, the driving part 131 is configured in a U-shaped structure and has two mounting side walls. The limiting part 132 is integrally connected with one of the mounting side walls away from the row of nail limiting blocks 18. The limiting part 13 of this structure can quickly respond to the corresponding rotation under the pressure of the row of nails and the action of the spring 14, so as to ensure the smooth pushing of the row of nails and the timely limiting after the smooth pushing.
[0037] Embodiment Two
[0038] Referring to Figure 8 On the basis of the first embodiment, the support body 1 is also optimized and improved in this embodiment, and the purpose is to further expand the area of the bottom surface 2 for supporting. Specifically, the support body 1 is configured in an inverted trapezoidal plate structure. The support body 1 integrally extends out a spreading part 5 on both sides of the bottom. The bottom surface of the spreading part 5 is coplanar with the bottom surface of the support body 1 to form a combined bottom surface. The top of the spreading part 5 is gradually recessed and inclined from the inside to the outside. The recessed and inclined top reduces the outward protrusion of the top and the occupation of space as much as possible. The combined bottom surface expands the area of the original bottom surface 2, further increases the supporting surface area, and is more conducive to the adjustment of the verticality of the nail gun.
[0039] It is to be explained that the closed tail cover 300 is of an integrated structure, and the top connecting end 3 and the support body 1 can be integrally formed, and when the support body 1 is used, the support body 1 does not need to be separately installed, and as long as the closed tail cover 300 is installed, the support body naturally exists and can be directly used. For the top connecting end 3, the end of the shell 100 is installed, which does not affect the comfort of hanging and does not occupy too much space.
[0040] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technology content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution content of the present application, according to the technical essence of the present application, still belongs to the protection scope of the technical solution of the present application.
