Nail shooting device without firing spring

Abstract

The invention discloses a nail shooting device without a firing spring. The nail shooting device without the firing spring comprises a nail tube, a nail tube fixing sleeve, a nail tube pressure spring, a firing needle and a firing needle seat, wherein one end of the nail tube fixing sleeve is fixedly arranged on the nail tube in a sleeving manner while the other end of the nail tube fixing sleeveis movably arranged on the firing needle seat in a sleeving manner; one end of the firing needle is fixed on the firing needle seat while the other end of the firing needle is positioned in the nail tube; and one end of the nail tube pressure spring is arranged on the nail tube in a sleeving manner while the other end of the nail tube pressure spring is arranged on the firing needle in a sleevingmanner. A plurality of parts such as a firing pin, a firing pin pressure spring, a firing column, a firing plate and a firing column pressure spring in an existing pressing type nail shooting device are omitted, the structure of the nail shooting device is greatly simplified, and the manufacturing cost, the failure rate, the maintaining cost and the like are greatly reduced. Correspondingly, a to-be-fired state in a firing process is further omitted, the purposes of simplifying a firing processing, improving firing efficiency and the like are achieved, and furthermore, withdrawing of a shell case is facilitated.

Description

technical field [0001] The invention relates to the technical field of nail fastening, in particular to a nail shooter without a firing spring. 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-t...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned nail shooter still has the following defects: one, the firing mechanism includes various parts such as firing pin, firing pin stage spring, firing column, firing sheet, firing post stage stage spring, etc., because the structure of these parts is exquisite and small and exquisite, therefore causes the whole The structure of the nail shooter is complicated and the cost increases

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

6. The number of parts of this type of nail shooter is between 18 and 25, and the number of parts is large, which not only leads to higher manufacturing costs, but also has higher requirements for manufacturing technology, manufacturing quality and assembly technology.
