Problems solved by technology

In order to meet the requirements of the national standard, the existing hammer-type nail shooter needs to design multiple resistance ring mechanisms inside the firing mechanism of the nail shooter, so as to meet the requirement that the nail shooter cannot produce nails when it falls from a height of 3 meters. Although this design can make the nailer meet the requirements, it will also cause the nailer to have problems such as complex structure, high manufacturing cost, and poor reliability.

Embodiment 1

[0039] Figure 2 to Figure 5 Shown is a firing mechanism provided by the present invention, including a firing pin cover 11, a firing pin 12 and a hammer 14 for firing the firing pin 12; a resistance spring is provided between the hammer 145 and the firing pin cover 11 13.

[0040] The interior of the firing pin cover 11 includes a firing pin 12 installation cavity, a resistance spring 13 installation cavity, and a hammer 14 installation cavity. And the diameter of the installation cavity of the firing pin 12 is greater than the diameter of the installation cavity of the resistance spring 13, and the diameter of the installation cavity of the resistance spring 13 is greater than the diameter of the installation cavity of the hammer 14, so that the connection between the installation cavity of the firing pin 12 and the resistance spring 13, the resistance The connection between the installation cavity of the spring 13 and the installation cavity of the hammer 14 is stepped; th...

Embodiment 2

[0049] The difference between this embodiment 2 and embodiment 1 is:

[0050] Embodiment 2 provides a firing mechanism. The firing pin 12 and the hammer 14 are integrated. Specifically, the firing pin 12 and the hammer 14 are integrally formed, or the firing pin 12 and the hammer 14 are welded and fixed; When the nailer falls freely, the hammer 14 moves forward rapidly under the action of inertia. When the hammer 14 is moving, the firing pin 12 integrally arranged with the hammer 14 moves synchronously with the hammer 14, and the hammer 14 is moving. During the process, due to the cooperation between the resistance spring 13 and the disc on the hammer 14, the resistance spring 13 can block the hammer 14, thereby greatly reducing the inertia of the hammer 14, so that the inertia of the firing pin 12 hitting the nail bullet Greatly reduced, effectively preventing the firing pin 12 from hitting the nail bullet, so that the nail shooter cannot be fired, so that the nail shooter me...

Embodiment 3

[0052] The difference between this embodiment 3 and embodiment 1, embodiment 2 is:

[0053] Such as Figure 6 to Figure 8 As shown, Embodiment 3 provides a hammer-type nail shooter, including a firing mechanism, a connecting mechanism and the above-mentioned firing mechanism; the firing mechanism and the firing mechanism are respectively installed at both ends of the connecting mechanism, and the tail of the firing pin Corresponds to the firing end of the firing mechanism.

[0054] The firing mechanism is used to fire the nail, and the firing mechanism is used to fire the nail bullet. When the nail bullet is fired, the nail bullet explodes, thereby driving the firing mechanism, so that the firing mechanism fires the nail The connecting mechanism is used for the connection between the firing mechanism and the firing mechanism, by corresponding the tail of the firing pin 12 in the firing mechanism to the firing end of the firing mechanism, so that the firing pin 12 can directly...

Abstract

The invention discloses a firing mechanism and a hammering type nail shooting device with the firing mechanism, and relates to the field of nail shooting fastening equipment. The firing mechanism comprises a firing pin sleeve, a firing pin and a firing hammer used for the firing of the firing pin, and a resistance spring is arranged between the firing hammer and the firing pin sleeve. When a nailshooting device falls freely, the hit of the firing pin to a nail shooting bullet is prevented, so that the nail shooting device is not struck, the national standard of China is met, and the firing mechanism is simpler in structure, lower in cost and higher in stability, and is more convenient to assemble.

Description

technical field [0001] The invention relates to the field of nail-shooting and fastening equipment, in particular to a firing mechanism and a hammer-type nail shooter with the firing mechanism. Background technique [0002] At present, most of the firing pins in hammer nailers produced at home and abroad use eccentric firing, and the firing pin is in the shape of a spherical crown; The hammer hammers the firing pin to fire the nail bullet, so that the nail can complete the nail shooting operation. [0003] At present, my country's national standard requires that the nail shooter at home and abroad should not cause the nail shooter to strike when the nail shooter falls from a height of 3 meters. In order to meet the requirements of the national standard, the existing hammer-type nail shooter needs to design multiple resistance ring mechanisms inside the firing mechanism of the nail shooter, so as to meet the requirement that the nail shooter cannot produce nails when it fall...
