DETAILED DESCRIPTION

[0024] The following embodiments are only used to illustrate the possible implementation manners of the present application, but not used to limit the scope of the present application, and it is stated in advance.

[0025] Please refer to Figs. 1 to 7 which shows an embodiment of the present application, the hammer type nail gun 1 of the present application includes a body 10 and a nail driving mechanism 20.

[0026] The main body 10 is integrally formed by plastic, and comprises two side walls 11 and a top wall 12 connected between the two side walls 11. Each side wall 11 comprises an ear portion 111. The ear portion 111 of each side wall 11 comprises a stop point 112. A first position P1 and a second position P2 are respectively defined between the two ends of each side wall 11 and the stop point 112. The thickness of each side wall 11 gradually increases from the first position P1 and the second position P2 to the stop point 112. The thickness of each side wall 11 gradually increases from the top wall 12 to the stop point 112. The striking mechanism 20 is pivotally connected to the two side walls 11 and can be swung to abut against the stop point 112. The striking mechanism 20 comprises a nail magazine 21 and a striking member 22. The nail magazine 21 is movably arranged between the two side walls 11 relative to the main body 10. The striking member 22 is movably arranged above the nail magazine 21 relative to the main body 10. The striking member 22 is used to strike out the nails in the nail magazine 21. Thus, the hammer-type nail gun 1 has the advantages of light weight, high structural strength, durability, etc.

[0027] In the embodiment, the main body 10 is integrally formed by single plastic (e.g. PC material) without containing fibers. For example, the main body 10 is integrally formed by polymer plastic and composite material, which has the advantages of environmental protection and light weight. The overall structure can be designed according to the ergonomic analysis of the operator, the weight ratio of each part for the best labor saving and force application, and the use habits of users in different regions. The local reinforcement design is performed according to the force application situation of the handle. The overall structure is controlled in thickness ratio and operation center of gravity according to the requirements of the force application part. The operation is convenient, the hammering is efficient, and the structure is strong.

[0028] When the hammering force is applied, the main body 10 and the striking mechanism 20 move relatively close to each other. The stop point 112 can limit the distance of relative movement, so as to avoid that the swing amplitude is too large, the impact between the striking mechanism 20 and the main body 10 is too large, and the structure is damaged. The stop point 112 can be provided with a pin arranged between the two side walls 11, can be provided with a stop block integrally extended from the two side walls 11, or any element or structure capable of stopping the striking mechanism 20.

[0029] Preferably, each side wall 11 has a maximum thickness at a position adjacent to the stop point 112. The ear portion 111 of each side wall 11 further comprises an arch 113 protruding away from the top wall 12 and extending around the stop point 112. The arch 113 has a thickness greater than the thickness of the part of the side wall 11 connected to the top wall 12. Thus, the structural strength of the part connected to the striking mechanism 20 and the adjacent part (the part receiving the maximum impact force during hammering) is improved, so as to avoid breakage or damage during hammering.

[0030] In detail, each of the side walls 11 further comprises a first gradually thickened section 13 gradually thickened from the first position P1 to the stop point 112, a second gradually thickened section 14 gradually thickened from the first gradually thickened section 13 to the stop point 112, a third gradually thickened section 15 gradually thickened from the first position P2 to the stop point 112, a fourth gradually thickened section 16 gradually thickened from the third gradually thickened section 15 to the stop point 112, a fifth gradually thickened section 17 gradually thickened from the top wall 12 to the stop point 112, and a sixth gradually thickened section 18 gradually thickened from the fifth gradually thickened section 17 to the stop point 112. Each of the side walls 11 is smoothly and gradually thickened in different directions, so that the force can be evenly dispersed and transmitted in all directions, and the stress concentration point (easily broken point) can be avoided.

[0031] Preferably, the extension length L2 of the second gradually thickened section 14 is greater than the extension length L1 of the first gradually thickened section 13, the extension length L4 of the fourth gradually thickened section 16 is greater than the extension length L3 of the third gradually thickened section 15, and the extension length L5 of the fifth gradually thickened section 17 is greater than the extension length L6 of the sixth gradually thickened section 18. In this way, the maximum structural strength can be provided at the connection between each of the side walls 11 and the nail hitting mechanism 20 and the adjacent part thereof, so that the rupture or breakage can be avoided.

[0032] In the present embodiment, each of the side walls 11 is divided into a first section 11a and a second section 11b by the stop point 112, the first section 11a is the handle side, and the second section 11b is the hammer working side. A first ratio of a first distance D1 from the first position P1 to the stop point 112 to a length L7 of the first section 11a is 0.615 to 0.815, and a second ratio of a second distance D2 from the first position P2 to the stop point 112 to a length L8 of the second section 11b is 0.305 to 0.505. The above values can be designed and changed according to factors such as labor-saving and force application effect, weight ratio of each part, user usage habit in different regions, etc.

[0033] Preferably, the main body 10 further comprises at least one cutout 114 provided in at least one of the side walls 11, and the nail hitting mechanism 20 further comprises a bottom plate 23 provided on the lower side of the nail magazine 21, the bottom plate 23 comprising at least one card protrusion 231 inserted into the at least one cutout 114, so that the main body 10 and the nail hitting mechanism 20 can be prevented from moving forward and backward relative to each other. The main body 10 further comprises at least one recessed recess 115 provided in the inner face of at least one of the side walls 11, and the bottom plate 23 further comprises at least one recessed protrusion 232 inserted into the at least one recessed recess 115, so that the combination stability, strength and reliability of the main body 10 and the nail hitting mechanism 20 can be enhanced.

[0034] The main body 10 is made of PC material and is thickened appropriately to effectively increase the structural strength of the main body 10. As shown in the following example test results, with one end of the main body 10 as a fixed end and a force of 50 kgf applied to the other end of the main body 10, the deformation displacement of the other end of the main body 10 is about 25.8 mm; under the same test conditions, the deformation displacement of the main body of a conventional hammer type nail gun without thickening is about 44.7 mm under a force of 50 kgf. As can be seen from the above, the structural strength of the main body 10 of the present application can be greatly improved after being thickened appropriately.

[0035] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
