Description

Technical Field

[0001] The utility model relates to the technical field of nail fastening, in particular to a plastic shell nail bullet for thumbtacks. Background Art

[0002] A thumbtack is a nail whose end is longer and thicker than the cap of an ordinary nail. Because its end is larger than the cap of an ordinary nail, it is equivalent to having a large head section, so it is collectively called a thumbtack in the industry. At present, common thumbtacks include threaded nails, eye nails, thick cap nails, etc. Among them, threaded nails refer to thumbtacks with threads in the large head section, eye nails refer to thumbtacks with eye holes in the large head section, and thick cap nails refer to thumbtacks with longer and thicker large head sections. Different thumbtacks have their own uses. For example, after threaded nails and eye nails are fixed on substrates such as pipes, steel parts, doors and windows, and brackets, other fasteners can be connected through the threads and eye holes on the nails, respectively, so as to install and fix the actual fasteners. Because of its advantages of easy use and good fixing effect, it is becoming more and more widely used.

[0003] In the prior art, a thumbtack is usually embedded in the plastic cartridge column of a plastic shell nail bullet. For example, the patent document with the announcement number CN218151893U discloses an eyelet ceiling integrated nail, which can quickly fix the nail with an eyelet on the base by detonating the plastic shell nail bullet through the impact of the firing pin of the nail shooter. Although the prior art represented by this patent document can achieve the rapid fixation of the thumbtack, the applicant has found through actual experiments that since the thumbtack and the cartridge column are usually connected by injection molding, that is, the cartridge column is fixed to the end of the thumbtack by injection molding, after the thumbtack is driven into the base by the plastic shell nail bullet, some plastic residues usually remain on the big head section of the thumbtack, which requires the use of additional tools to remove the residues before continuing the construction, which not only increases the construction process, but also affects the construction efficiency. Especially for some construction areas with narrow space, it is inconvenient to use tools to remove the residues.

[0004] In summary, it is necessary to provide a new type of plastic shell nail bullet that can prevent residue from remaining on the thumbtack and improve construction efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned technical problems existing in the prior art, and provide a plastic shell nail bullet for thumbtacks. The utility model is provided with an embedding hole for preventing residue residue on the cartridge column at one end relative to the thumbtack. The embedding hole can prevent plastic residue from remaining on the thumbtack's big head section after the thumbtack is driven into the base, thereby solving the technical problems of the prior art that an additional tool is needed to remove the residue and that the construction efficiency is affected.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A plastic shell nail bullet for thumbtacks comprises a cartridge column, one end of which is provided with explosive material, and is characterized in that the other end of the cartridge column is provided with an embedding hole matched with the thumbtack's thumbtack section.

[0008] The embedding hole is arranged coaxially with the cartridge column.

[0009] The embedding hole includes a guide section and a positioning section, the longitudinal sections of the guide section and the positioning section are respectively an isosceles trapezoid and a rectangle, the inner diameter of the positioning section is adapted to the inner diameter of the big head section, the inner diameter of the opening end of the guide section is larger than the outer diameter of the big head section, and the big head section of the thumbtack can enter the positioning section through the guide section.

[0010] The embedded hole also includes a limiting section, which is located between the hole bottom and the positioning section and is adapted to the chamfer of the end of the large head section.

[0011] The embedded hole is a straight hole or a tapered hole.

[0012] The depth of the embedded hole is 1-3 mm.

[0013] By adopting the above technical solution, the beneficial technical effects of the utility model are:

[0014] 1. The utility model has an embedding hole at the end of the cartridge column that matches the big head section of the thumbtack. In actual application, the plastic shell nail bullet can be placed into the nail tube of the nail shooter first, and then the thumbtack is placed into the nail tube and the big head section is inserted into the embedding hole; or the big head section of the thumbtack can be placed into the embedding hole first, and then both can be placed into the nail tube together. Since the embedding hole matches the big head section, that is, the embedding hole is only slightly larger than the big head section, and both are independent split structures, after the plastic shell nail bullet explodes to generate power to drive the thumbtack into the substrate, no plastic residue will remain on the big head section.

[0015] 2. The utility model sets the embedding hole and the cartridge column as a coaxial centerline structure, which can achieve the function and effect of automatically aligning the axis centerline after the thumbtack enters the embedding hole in actual application, thereby achieving a good power transmission effect.

[0016] 3. The utility model cooperates with the guide section, the positioning section and the limit section, which is helpful for the large head section to accurately enter the embedded hole and automatically find the axis center line in actual application, thereby achieving an effective fixing effect.

[0017] 4. The embedding hole in the utility model can also be a straight hole or a tapered hole, which is conducive to meeting the needs of different working conditions or the needs of different shapes of thumbtacks.

[0018] 5. The utility model sets the depth of the embedding hole to 1-3mm, which can position the big head section of the thumbtack on the one hand. When the plastic shell nail bullet and the thumbtack enter the nail tube, the big head section automatically enters the embedding hole for positioning, thereby ensuring a better shooting effect. On the other hand, after shooting, since the depth of the embedding hole section is relatively shallow, the power generated by the explosion can shatter the plastic of the embedding hole section and automatically fall off from the nail head without remaining on the nail head.

[0019] 6. In the utility model, since the thumbtacks and the plastic shell nail bullets are separated, they can be transported in different categories during the delivery process, which is beneficial to improving the safety of transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 The utility model shows a structural schematic diagram of a plastic shell nail bullet for a thumbtack. Figure 2 The schematic diagram shows the structure of the thumbtack entering the embedded hole. Figure 1 , 2 It can be seen that the plastic nail bullet includes a cartridge column 1, one end of which is provided with an explosive material 2, and the other end of the cartridge column 1 is provided with an embedding hole 3 adapted to the big head section of the thumbtack 7. The big head section of the thumbtack 7 can be embedded in the embedding hole 3 in actual application, but since the embedding hole 3 and the thumbtack 7 are both independent structural parts, the embedding hole 3 only plays a positioning role for the thumbtack 7, so no plastic residue will remain on the big head section after the plastic shell nail bullet explodes, so the process of using tools to remove plastic residue can be reduced during construction, which is not only conducive to improving construction efficiency, but also particularly suitable for working areas with narrow space.

[0024] It should be noted that the utility model does not limit the structure of the plastic shell nail bullet, and any conventional structure known in the art can be used. The key improvement of the utility model is to change the existing one-piece structure of the cartridge column 1 embedded and connected to the large head section into a split structure, and to solve the problem of plastic residue residue by providing a matching embedding hole 3 at the end of the cartridge column 1.

[0025] According to a preferred embodiment of the present invention, the embedding hole 3 is coaxially arranged with the cartridge column 1, that is, the axis of the embedding hole 3 coincides with the axis of the cartridge column 1. Based on this, in practical application, the tack 7 can automatically align the axis after entering the embedding hole 3.

[0026] According to another preferred embodiment of the utility model, the embedded hole 3 includes a guide section 4, a positioning section 5 and a limiting section 6 from the outside to the inside, the limiting section 6 is located between the bottom of the embedded hole 3 and the positioning section 5, the positioning section 5 is located between the limiting section 6 and the guide section 4, the longitudinal sections of the guide section 4, the positioning section 5 and the limiting section 6 are isosceles trapezoid, rectangle and isosceles trapezoid respectively, the inner diameter of the positioning section 5 is adapted to the inner diameter of the big head section, the limiting section 6 is adapted to the chamfer of the end of the big head section, and the inner diameter of the open end of the guide section 4 is larger than the outer diameter of the big head section. In actual application, the big head section of the thumbtack 7 can accurately and smoothly enter the positioning section 5 and the limiting section 6 through the guide section 4, so that the thumbtack 7 can automatically find the axis center line to achieve a better fixing effect.

[0027] According to an alternative embodiment of the present invention, for different working conditions or different shapes of thumbtacks 7, the embedding hole 3 can also be a straight hole or a tapered hole.

[0028] According to another preferred embodiment of the present invention, the depth of the embedding hole 3 can be 1-3 mm. Specifically, the depths of the guide section 4, the positioning section 5 and the limiting section 6 can be 0.5 mm, 2 mm and 0.5 mm respectively.

[0029] When the utility model uses a nail shooter to fasten the thumbtack 7, there are two loading methods. The first is that before shooting, the cartridge column 1 containing the explosive material 2 is first loaded into the nail tube, and then the thumbtack 7 is loaded and the nail tube is compressed. During the compression process, the big head section of the thumbtack 7 will automatically enter the positioning section 5 and the limiting section 6 under the guidance of the guide section 4 and automatically find the axis center line. After the loading is completed, the nail shooter detonates the plastic shell nail bullet to accurately drive the thumbtack 7 into the matrix. The second method is to first put the big head section of the thumbtack 7 into the embedded hole 3 before shooting, and then put the two together into the nail tube, which can also accurately drive the thumbtack 7 into the matrix. Since there is no fixed connection structure between the embedded hole 3 and the thumbtack 7, there will be no plastic residue left on the big head section after the plastic shell nail bullet explodes, which not only reduces the process of using tools to remove plastic residues, but also improves construction efficiency, and is particularly suitable for construction in narrow working conditions.

[0030] The above description is only a specific implementation method of the present utility model. Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes; all disclosed features, or all methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any way.
