Improved nail shooting device

Abstract

The invention discloses an improved nail shooting device comprising a firing mechanism and a nail pipe assembly. The firing mechanism comprises a sliding sleeve, a firing needle, a firing needle seat,a firing needle seat pressure spring and a connecting sleeve. The connecting sleeve is fixed to one end of the sliding sleeve, the nail pipe assembly is movably arranged at the other end of the sliding sleeve, one end of the firing needle is located in a nail pipe of the nail pipe assembly, and the other end of the firing needle is fixedly connected with the firing needle seat. The firing needleseat is movably arranged in the sliding sleeve, and the firing needle seat pressure spring is arranged between the firing needle seat and the connecting sleeve. According to the improved nail shootingdevice, the parts, such as a firing pin, a firing pin pressure spring, a firing column, a firing piece and a firing column pressure spring, in an existing pressing type nail shooting device are omitted, the purposes that the structure of the nail shooting device is simplified, the manufacturing cost is reduced, the failure rate is decreased, and the maintenance cost is reduced are achieved, correspondingly, the to-be-fired state in the firing process is further omitted, the purposes that the firing procedure is simplified and the firing efficiency is improved are achieved, and additionally ejection of shell cases is easier.

Description

technical field [0001] The invention relates to the technical field of nail fastening, in particular to an improved nail shooter. Background technique [0002] The nailer is a tool that uses the gunpowder gas generated by firing nail bullets as power to drive nails into buildings. The use of the nailer for nail fastening technology is an advanced modern fastening technology. Compared with traditional pre-embedded fixing, hole pouring, bolt connection, welding and other methods, it has many advantages: it has its own energy and gets rid of wires It is convenient for on-site and high-altitude operations; the operation is fast and the construction period is short, which can greatly reduce the labor intensity of construction personnel; save funds and reduce construction costs. [0003] At present, commonly used nail shooters are usually push-type nail shooters. For example, the prior art with the Chinese patent announcement number "CN205704031U" disclosed a push-type nail shoot...

AI Technical Summary

Problems solved by technology

But this class nail shooter still exists following defect in actual use process: one, firing mechanism comprises various parts such as percussion pin, percussion pin stage clip, percussion post, percussion piece, percussion post stage clip, etc., because these parts The structure is exquisite and small, so the structure of the whole nail shooter is complicated and the cost is increased

Correspondingly, it is more difficult for the manufacturing process, manufacturing quality and assembly process of the nail shooter

2. Both the firing pin compression spring and the firing column compression spring are vulnerable parts, especially the firing pin compression spring, whose average service life is about 1,000 rounds, that is, the firing pin pressure needs to be replaced every time about 1,000 nail shooting rounds are fired. Spring, because the structure of the nail shooter is relatively complicated, it not only makes the replacement process complicated, but also increases the failure rate of the nail shooter

Correspondingly, there are defects such as high failure rate, high maintenance cost and short maintenance cycle

3. The firing mechanism includes the structure of various parts such as the firing pin, the firing pin compression spring, the firing column, the firing piece, the firing column compression spring, etc., so that the nail shooter is in a ready-to-fire state during the firing process, which leads to the failure of the nail shooter. The firing time is longer and the firing process is more complicated

4. During the ejection process, if the cartridge case is stuck in the barrel too tightly, the cartridge case will push the firing pin and the firing pin seat and compress the firing spring to move backward, and because the force of the firing spring is too large, the compression process will be laborious, which will cause Difficulty in shelling

5. Due to the strong force of the firing spring, it is more laborious to compress the barrel to fire, and the feeling of fatigue is strong during long-term use
