[0045] like Figure 1-8 As shown, the utility model provides an anti-dropping nail, comprising:

[0046] The nail body 1 is used to be nailed into an object. The nail body 1 is divided into a spike section 11, a rod section 12 and a nail cap section 13 from one end to the other. The rod section 12 includes a first rod 121 and a second rod 122 connected in sequence. The first rod 121 is close to the spike section 11, and the second rod 122 is close to the nail cap section 13. The second rod 122 has an anti-slip protrusion 123 on the side wall. The anti-slip protrusion 123 is strip-shaped, X-shaped or spiral-shaped. The firing assembly 2 is arranged on the nail cap section 13 of the nail body 1. The firing assembly 2 is used to push the nail body 1 to be nailed into the object after being fired.

[0047] In this embodiment, Figure 1As shown, the presence of the anti-skid protrusion 123 can increase the friction between the surface of the nail body and the object after the nail body 1 is nailed into the object, thereby improving the firmness. In addition, when the anti-skid protrusion 123 is spiral, the nail body 1 will rotate to a certain extent during the process of being nailed into the object, making the fixation more secure, preventing the nail from detaching from the object, and better improving the stability.

[0048] Furthermore, the anti-skid protrusions 123 are arranged along the length direction of the second rod 122 , and a plurality of anti-skid protrusions 123 are evenly arranged along the circumference of the second rod 122 .

[0049] In this embodiment, Figure 1 As shown, a plurality of anti-slip protrusions 123 are provided to further increase the friction between the nail body 1 and the object, thereby preventing the nail body 1 from falling out of the object.

[0050] Furthermore, the anti-skid protrusions 123 are strip-shaped, and a strip-shaped recess 4 is formed between two adjacent anti-skid protrusions 123 . The strip-shaped recess 4 gradually narrows from a position close to the second rod 122 to a position far away from the second rod 122 .

[0051] In this embodiment, Figure 7 and Figure 8 As shown, a strip-shaped recess 4 is formed between two adjacent strip-shaped anti-slip protrusions 123. The longitudinal section of the strip-shaped recess 4 is similar to a trapezoid, with a narrow opening side and a wide side close to the second rod 122. In this way, when the nail body 1 is nailed into an object, a part of the object will be squeezed into the strip-shaped recess 4. The squeezing force of part of the material of the object in the strip-shaped recess 4 will greatly increase the friction force, thereby significantly improving the firmness. In addition, as shown in FIG. Figure 7 and Figure 8 As shown, one end of the anti-slip protrusion 123 close to the first rod 121 is smoothly connected to the second rod 122, and one end of the strip recess 4 facing the first rod 121 has a guiding slope, which can facilitate the material to enter the strip recess 4 and reduce resistance.

[0052] Furthermore, the diameter of the second rod 122 is greater than or equal to the diameter of the first rod 121 .

[0053] In this embodiment, the diameter of the first rod 121 is smaller than the diameter of the second rod 122. In the process of the nail body 1 being nailed into an object, the spike section 11 first contacts and penetrates the object, and then the first rod 121 part with a smaller diameter enters the object. The first rod 121 is easier to penetrate into the object than the second rod 122, which can reduce the hole diameter of the object to be nailed, and reduce damage to the object. Then, the smaller hole formed by the puncture of the spike section 11 and the first rod 121 part is further penetrated and expanded by the second rod 122 with a larger diameter. In this way, the gradually expanded hole will have better integrity and better fastening force, making the nail body 1 nailed in more firmly, and at the same time can reduce the burden during the penetration process. Under the same force, it can be nailed into the object more quickly.

[0054] Furthermore, the length of the first rod 121 is smaller than the length of the second rod 122 .

[0055] In this embodiment, the length of the first rod 121 is less than that of the second rod 122, which can effectively reduce the possibility of partial bending of the first rod 121, improve the stability in use, and maximize the overall strength of the nail body 1 while meeting the nail penetration strength.

[0056] Furthermore, the maximum diameter of the spike segment 11 is smaller than or equal to the diameter of the second rod 122 , and larger than or equal to the diameter of the first rod 121 .

[0057] In this embodiment, the spike segment 11 is in the shape of a rotating body, and the diameter gradually decreases from the middle to the two ends. In the process of the spike segment 11 being nailed into the object, there will be a process of rapid expansion of the perforation, which can give the nailed part a pre-expanded aperture. The spike segment 11 is short in length, and in this rapid nailing process, the damage to the nailed object can be effectively reduced. Then the nailing process of the first rod 121 is easier, and further the second rod 122 is nailed into the object, thereby improving the overall nailing speed and reducing the possibility of damaging the object.

[0058] Furthermore, the launching assembly 2 includes a column 21 and an insert block 23. One end of the column 21 is arranged on the nail cap section 13, and the other end has a first groove 22. The insert block 23 is used to be inserted into the first groove 22. One end of the insert block 23 has a second groove 24. After the insert block 23 is inserted into the first groove 22, a receiving cavity 25 is formed between the second groove 24 and the bottom of the first groove 22.

[0059] In this embodiment, the column 21 and the insert block 23 are a combined structure. During the nail production process, the explosive filler (generally nitrocellulose) is placed in the second groove 24, and then the insert block 23 is inserted into the first groove 22, thereby forming a receiving cavity 25, and the explosive filler is located in the receiving cavity 25.

[0060] Furthermore, the launch assembly 2 also includes a block 26 , which is disposed at the bottom of the first groove 22 , with a gap between the block 26 and the inner wall of the first groove 22 . After the insert block 23 is inserted into the first groove 22 , the block 26 is inserted into the second groove 24 .

[0061] Furthermore, the clamping block 26 is cylindrical, and one end of the clamping block 26 that is clamped into the second groove 24 has a tapered guide surface 27 .

[0062] In this embodiment, the tapered guide surface 27 can facilitate the insertion of the block 26 into the second groove 24 .

[0063] Furthermore, the first groove 22 is divided into a first section 221 and a second section 222 from the opening to the bottom of the groove. The first section 221 is truncated cone-shaped, the second section 222 is cylindrical, and the plug block 23 is a rotating body. After the plug block 23 is inserted into the first groove 22, the side wall of the plug block 23 fits with the inner wall of the first groove 22.

[0064] In this embodiment, the side wall shape of the plug block 23 is the same as that of the first groove 22. The truncated cone-shaped first section 221 can more conveniently insert the plug block 23 therein and play a guiding role. In addition, the wedge-shaped surface can provide a tapered force for the plug block 23, making the fixation of the plug block 23 more secure.

[0065] Furthermore, an annular groove 28 is provided on the side wall of the first groove 22, and an annular protrusion 29 is provided on the side wall of the plug block 23. After the plug block 23 is inserted into the first groove 22, the annular protrusion 29 is inserted into the annular groove 28, and the connection between the plug block 23 and the first groove 22 is more firmly connected, thereby improving the overall firmness and stability. The annular groove 28 is located on the first section 221, and the diameter of the annular protrusion 29 is larger than the minimum diameter of the first section 221 and smaller than the maximum diameter of the first section 221.

[0066] In this embodiment, the diameter of the annular protrusion 29 is smaller than the maximum diameter of the first section 221. In this way, when the plug block 23 is inserted into the first groove 22, the end of the first groove 22 will not support the annular protrusion 29. The annular protrusion 29 can be inserted into the annular groove 28 under the gradual guiding effect of the inner wall of the first section 221, which makes the operation more convenient.

[0067] Furthermore, a firing groove 3 is formed at one end of the insert block 23 away from the second groove 24 .

[0068] In this embodiment, Figure 4 As shown, the firing groove 3 is in the shape of a truncated cone. The existence of the firing groove 3 can reduce the wall thickness of the insert block 23 at that location. When firing a nail, it can be easier to penetrate the firing groove 3 and complete the firing. The truncated cone design can play a certain guiding and positioning role, and is more conducive to correctly hitting the firing groove 3.

[0069] 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 preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
