Description

Nail pipe capable of preventing fastener from falling

Technical Field

The utility model belongs to the technical field of penetrate the nail fastening, concretely relates to prevent nail pipe that fastener dropped.

Background

The nail shooter is also called as nail shooting gun, which is a fastening tool for driving a nail into a building by using a blank cartridge, gas or compressed air as power. The fastening technology of the nail shooter is an advanced modern fastening technology, and compared with the traditional methods of pre-embedding and fixing, punching and pouring, bolt connection, welding and the like, the fastening technology of the nail shooter has many advantages that: the energy is provided, so that the encumbrance of electric wires and air pipes is avoided, and the field and high-altitude operation is facilitated; the operation is quick, the construction period is short, and the labor intensity of workers can be greatly reduced; reliable and safe action, and even can solve some construction problems which are difficult to solve in the past; the capital is saved, and the construction cost is reduced.

The existing nail shooters usually have two types, namely a handheld nail shooter and an axial nail shooter, such as a compressed air nail shooter disclosed by the publication number CN103085033A and a silent nail shooter launching tube and a nail shooter disclosed by the publication number CN 210414410U. The principle of the two nail shooters is that a piston rod moves towards a nail tube under the action of driving force, and then a fastener which is placed in the nail tube in advance is driven into a base body to be fixed. But since the outer diameter of the fasteners is smaller than the inner diameter of the nail tube, the fasteners are movable inside the nail tube, and therefore will inevitably fall out of the nail tube when the mouth of the nail tube is facing downwards. Therefore, the requirement is that the constructor avoids the pipe orifice of the nail pipe facing downwards in the construction process, and the labor intensity of the constructor is correspondingly increased. The fastener is movable in the nail tube, so that when the fastener is driven into the base body, the fastener is required to be held by hands to align with a point to be driven, on one hand, the construction difficulty is increased, and the construction efficiency is influenced; on the other hand, there is a technical problem of affecting safety.

In addition, the existing solutions are to assemble a rubber or plastic retainer ring on the nail tube, which is larger than the aperture of the nail tube, so that the fastener is not dropped when being assembled. However, in some special application scenarios, the fastener is required to have no additional accessories, or the retainer ring cannot be installed at all due to the structural limitation of the fastener. Therefore, it is necessary to develop a new technology to solve the above technical problems.
