Description

Technical Field

[0001] The utility model relates to the field of nail-shooting fasteners, in particular to a novel expansive structural nail-shooting component. Background Art

[0002] In the prior art, nails are commonly used parts for installing suspended ceilings and doors and windows. Compared with expansion bolts, they are quick and convenient to install, and are quite popular in the suspended ceiling and door and window installation markets. Traditional nails are usually composed of a single nail with a smooth surface and no expansive structure. After being shot into the installation base, the nail is connected to the installation base only by the very small extrusion force generated when the nail is shot into the installation base, which is easy to loosen, fall off, and has poor stability. In addition, traditional expansion bolts have an expansive structure, and have a large extrusion friction force when connected to the installation base, and have good stability. However, when fixing objects, holes need to be drilled in advance and then installed. They are not as quick and convenient to install as nails, and the construction has the disadvantages of high installation cost, high labor intensity for workers, and time-consuming and labor-intensive. Utility Model Content

[0003] In order to overcome the problems in the prior art that traditional nails have no expansive structure and are prone to loosening, falling off and poor stability due to low extrusion friction when connected to the installation base; in order to overcome the problems that traditional expansion bolts are not as fast and convenient to install as nails, and have high installation costs, high labor intensity for workers, and are time-consuming and labor-intensive, the utility model provides a nail assembly with an expansive structure and the ability to be quickly and conveniently installed.

[0004] In order to achieve the above-mentioned invention object, the technical scheme adopted by the utility model is: a new type of expandable structure nail assembly, including a nail assembly body, the nail assembly body, including a nail body, an expansion sleeve, a gasket, and a fastening nut, forming a nail assembly with an expandable structure and quick and convenient installation. The nail assembly body is made of an integrally formed nail body as the main body of the nail assembly, and the nail body includes a nail body nail tip, a nail head tapered expansion boss, a nail body nail rod, and a nail rod thread at the rear end of the nail body. The new type of expandable structure nail assembly, The nail tip of the nail body is set to a pointed bullet shape, and the nail head of the nail body is provided with a nail head tapered expansion boss, which serves to provide an expansion force point for the expansion groove set at the front end of the expansion sleeve. The nail rod of the nail body is outer circle adapted to the expansion sleeve, and a gasket is provided at the tail end of the expansion sleeve. The diameter of the gasket hole matches the inner circle of the expansion sleeve, and a nail rod thread is provided at the rear end part of the nail body for installing a fastening nut to provide a force for the expansion sleeve. After tightening, the extrusion friction between the nail assembly and the installation base is greatly increased, so that the nail assembly is firmly connected to the installation base.

[0005] Furthermore, in the above-mentioned new expandable structural nail assembly, the nail body is integrally manufactured and formed, including a nail body nail tip, a nail head tapered expansion boss, a nail body nail rod, and a nail rod thread at the rear end of the nail body. The nail body nail tip is arranged in a pointed bullet head shape, which is convenient for shooting into the installation base layer. The nail head is provided with a nail head tapered expansion boss, which serves to provide an expansion force point for the expansion groove provided at the front end of the expansion sleeve. A nail rod thread is provided at the rear end part of the nail body for installing a fastening nut to provide a force for the expansion sleeve.

[0006] Furthermore, in the above-mentioned novel expandable structural nail assembly, the expansion sleeve includes an expansion groove, which utilizes the fulcrum provided by the tapered expansion boss of the nail head to expand the expansion groove under the force of the fastening nut at the rear end of the expansion sleeve, so as to expand the expansion groove outward and generate extrusion friction.

[0007] Furthermore, in the above-mentioned novel expandable structural nail assembly, the highest point of the outer diameter of the tapered expansion boss of the nail head provided on the nail body matches the outer diameter of the expansion sleeve, thereby preventing the expansion sleeve from being blocked from entering the installation hole when it is shot into the installation base.

[0008] The beneficial effects of the utility model are as follows: the expandable structure nail assembly of the utility model adopts an expandable structure, the extrusion friction formed with the installation base is high, the connection tightness is good, the stability is high, and at the same time, the nail shooting installation method is adopted, and the installation is quick and convenient.
