DETAILED DESCRIPTION
[0024] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.
[0025] Please refer to Figures 1 to 7 , which shows an embodiment of the utility model. The hammer nail gun 1 of the utility model includes a main body 10 and a nailing mechanism 20.
[0026] The main body 10 is integrally formed of plastic, and includes two side walls 11 and a top wall 12 connected between the two side walls 11. Each of the side walls 11 includes an ear 111, and the ear 111 of each of the side walls 11 includes a stop point 112. A first position P1 and a first position P2 are defined between the two ends of each of the side walls 11 and the stop point 112, respectively. The thickness of each of the side walls 11 gradually increases from the first position P1 and the first position P2 to the stop point 112, and the thickness of each of the side walls 11 gradually increases from the top wall 12 to the stop point 112. The nail driving mechanism 20 is pivotally connected to the two side walls 11 and can swing to abut against the stop point 112. The nail driving mechanism 20 includes a nail box 21 and a nail driving member 22. The nail box 21 can be movably located between the two side walls 11 relative to the main body 10. The nail driving member 22 can be relatively movably located above the nail box 21. The nail driving member 22 is used to drive out the nails in the nail box 21. Therefore, the hammer nail gun 1 of the utility model has the advantages of light weight, high structural strength, and durability.
[0027] In this embodiment, the main body 10 can be integrally formed of a single plastic (such as PC material) without fibers, which has the advantages of being environmentally friendly and lightweight. The overall structure can be designed based on the human factors analysis and the optimal weight ratio of each part for saving effort and applying force, and the user habits of different regions can be considered to carry out corresponding local reinforcement design for the force situation of the handle. In addition, the overall structure is matched with the requirements of the force-bearing part, and the thickness ratio and the center of gravity of the operation are controlled, so that the operation is smooth, the hammering is efficient, and the structure is strong.
[0028] When the hammer is applied, the main body 10 and the nail driving mechanism 20 will move closer to each other, and the stop point 112 can limit the relative movement distance to prevent the nail driving mechanism 20 and the main body 10 from having too large an impact due to excessive swing amplitude, thereby causing structural damage. The stop point 112 can be provided with a pin inserted between the two side walls 11, a stopper extending from the two side walls 11, or any element or structure that can stop the nail driving mechanism 20.
[0029] Preferably, each of the side walls 11 has a maximum thickness at a portion adjacent to the stop point 112, and the ear portion 111 of each of the side walls 11 further includes an arch 113 that protrudes in a direction away from the top wall 12 and extends around the stop point 112, and the arch 113 has a thickness greater than that of the portion of the side wall 11 connected to the top wall 12, thereby improving the structural strength at the connection with the nail driving mechanism 20 and its adjacent portion (the portion that is subject to the maximum impact force when hammering), thereby avoiding cracks and breakages when hammering.
[0030] In detail, each of the side walls 11 further comprises a first gradually thickening section 13 with a thickness gradually increasing from the first position P1 to the stop point 112, a second gradually thickening section 14 with a thickness gradually increasing from the first gradually thickening section 13 to the stop point 112, a third gradually thickening section 15 with a thickness gradually increasing from the first position P2 to the stop point 112, a fourth gradually thickening section 16 with a thickness gradually increasing from the third gradually thickening section 15 to the stop point 112, a fifth gradually thickening section 17 with a thickness gradually increasing from the top wall 12 to the stop point 112, and a sixth gradually thickening section 18 with a thickness gradually increasing from the fifth gradually thickening section 17 to the stop point 112. Each of the side walls 11 smoothly thickens in different directions, and can evenly disperse and transmit forces in an omnidirectional manner, thereby avoiding the existence of stress concentration points (prone breakage points).
[0031] Preferably, the extension length L2 of the second gradually thickening section 14 is greater than the extension length L1 of the first gradually thickening section 13, the extension length L4 of the fourth gradually thickening section 16 is greater than the extension length L3 of the third gradually thickening section 15, and the extension length L5 of the fifth gradually thickening section 17 is greater than the extension length L6 of the sixth gradually thickening section 18. Thus, the maximum structural strength is provided at the connection between each of the side walls 11 and the nail driving mechanism 20 and the adjacent parts to avoid cracking and breaking.
[0032] In this embodiment, each side wall 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 hammering 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 numerical values can be designed and changed accordingly according to factors such as labor saving and force application effects, weight ratios of various parts, and user habits of users in different regions.
[0033] Preferably, the main body 10 further includes at least one cutout 114 cut out of at least one of the side walls 11, and the nail driving mechanism 20 further includes a bottom plate 23 provided on the lower side of the nail magazine 21, and the bottom plate 23 includes at least one latching protrusion 231 inserted into the at least one cutout 114, so as to prevent the main body 10 and the nail driving mechanism 20 from moving forward and backward relative to each other; the main body 10 further includes at least one recess 115 recessed into the inner surface of at least one of the side walls 11, and the bottom plate 23 further includes at least one latching protrusion 232 inserted into the at least one recess 115, so as to enhance the combination stability, strength and reliability of the main body 10 and the nail driving mechanism 20.
[0034] The main body 10 is made of PC material and after being appropriately thickened, the structural strength of the main body 10 can be effectively increased. As shown in the following example test results, with one end of the main body 10 as the fixed end, a force of 50kgf is applied to the other end of the main body 10, and the deformation displacement of the other end of the main body 10 is about 25.8mm; under the same test conditions, the main body of the conventional hammer nail gun that has not been thickened is deformed and displaced by a force of 50kgf, which is about 44.7mm. It can be seen from the above that after the main body 10 of the utility model is appropriately thickened, its structural strength can be greatly improved.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
