Abstract
The invention discloses a nail bullet which comprises a shell. A propellant containing chamber is arranged in the shell. A propellant piece is loaded in the propellant containing chamber. The bottom of the shell is opened to form a center percussion hole that is communicated with the propellant containing chamber. The shell is made of steel and has a cone structure. The outer diameter of the bottom of the steel shell is less than the outer diameter of the top of the steel shell. The nail bullet improves the loading safety factor and has the advantages of simple loading, short production period and high usage reliability. The shell has a tapered design and thus the nail bullet can be loaded very easily. Moreover, propellant piece damage and even accidents caused by the operation that a piston cylinder is used to hit the propellant for loading can be avoided. The propellant piece whose end faces are bulgy and cambered is disposed in the shell so that any end surface of the propellant piece can easily touch the chamber bottom of the nail bullet device. The propellant piece can burn more fully, and the bursting force is stronger. With the nail bullet, the usage amount of nitrocotton can be effectively reduced, and the production cost can be further reduced.
Description
Technical field
The invention belongs to the fastening equipment technical field of nailing in building and repairs profession, particularly relate to a kind of nail shooting pill.
Background technology
At present, in the fastening equipment industry of nailing, various ail shooters are in building, nail shooting pill used is mainly traditional rim fire nail shooting pill (nail shooting pill) when fastening installation, about market consumption 10～1,500,000,000/year.Nearly 1～2 year, there is again a kind of nail shooting pill in market, and it and traditional nail shooting pill have certain difference, if shell is not copper shell or copper facing box hat, but plastic housing, it is not rim fire, but centre fire is commonly called as and moulds shell bullet.Although traditional nail shooting pill in use constant product quality, reliability is high, its assembling complexity and assembling security requirement are all high, thereby make that its technological process is long, manufacturing cost is higher.Some improvement on the basis of nail shooting pill, are done although mould shell bullet, but be plastic casing owing to moulding shell bullet, when work, tablet and plastic casing burn simultaneously, serious to the ablation of ail shooter core part cartridge chamber, add plastic casing incomplete combustion, cause residue to pile up many, shoot difficulty 2 times, thereby ail shooter continuous operation reliability is reduced, build fastening installation cost and increase.
And, this housing outer surface of moulding shell bullet is cylinder, close with the cartridge chamber shape and size in nailing tools, cause shooting and be difficult for putting in place, while often occurring shooting, mould shell bullet and be stuck in the situation of cartridge chamber, need to its shock be put in place with piston cylinder, easily break even and blast moulding ammunition in shell bullet, easily produce peace
Full hidden danger.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the invention provides a kind of quilt card thorax that is difficult for, shoot conveniently, assembling safety coefficient is high, with short production cycle, the nail shooting pill that dependability is high.
The technical solution used in the present invention is:
A kind of nail shooting pill, comprises housing, has powder charge chamber in housing, powder charge is filled with tablet in chamber, and housing bottom is offered the percussion hole, center communicating with powder charge chamber, and described housing is steel sheel, and steel sheel is conical structure, the bottom external diameter of steel sheel is less than the top external diameter of steel sheel.
Further, the neighboring of described steel sheel and end face are provided with zinc layer or copper layer.
This structure can prevent from getting rusty, and increases the service life.
Further, the tapering of described steel sheel is 2-5 degree.
Further, the external diameter of described tablet and powder charge chamber match, and the upper and lower end face of tablet is convex.
The cartridge chamber bottom connection that this structure is convenient in end face and the nailing tools of tablet touches, and makes tablet burning more fully, completely, and force of explosion is stronger, can effectively reduce the consumption of nitrocotton, further reduces manufacturing cost.
The invention has the advantages that:
1. improved assembling safety coefficient, assembling is simple, and with short production cycle, dependability is high.Not only effectively avoid that traditional nail shooting pill such as the production cycle is long, assembling security requirement is high, the more high defect of manufacturing cost, but also made up many defects of moulding shell bullet, improved reliability and the service life of ail shooter continuous operation.
2. housing adopts conical design, makes nail shooting pill be very easy to pack into and puts in place, and the percussion rate of penetrating pin can improve 50%, and can avoid being bound to position and causing tablet to damage with piston cylinder shock medicine unsafe thing even occurs
Therefore.
3. the tablet that end face is convex is housed in housing, and the cartridge chamber bottom connection of being convenient in end face and the nailing tools of tablet touches, and makes ammunition burning more fully, completely, and force of explosion is stronger, can effectively reduce the consumption of nitrocotton, further reduces manufacturing cost.

Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of nail shooting pill, comprise steel sheel 1, in steel sheel 1, have powder charge chamber 2, be filled with tablet 3 in powder charge chamber 2, the two ends of this tablet 3 are convex, the percussion hole, center 4 communicating with powder charge chamber 2 is offered in steel sheel 1 bottom, described steel sheel 1 is conical structure, and the bottom external diameter of steel sheel 1 is less than the top external diameter of steel sheel 1, and the tapering of steel sheel 1 outer surface is 3 degree.Be placed in the external diameter of powder charge chamber 2 Chinese medicine tablets 3 and the internal diameter in powder charge chamber 2 matches.
The neighboring of described steel sheel 1 and end face are provided with zinc layer (or copper layer) 5.
When use, nail shooting pill is put into the cartridge chamber of nailing tools, because steel sheel 1 is conical structure, little with cartridge chamber wall contact area, be therefore easy to pack into cartridge chamber, the situation that can avoid nail shooting pill to be stuck in cartridge chamber occurs.In addition, because the two ends of tablet 3 are convex, be not only conducive to tablet 3 and be assemblied in steel sheel 1, trigger better tablet 3 but also be conducive to striker, greatly improve the percussion qualification rate of nail shooting pill.And the nail shooting pill assembling of steel sheel 1 of the present invention is simple, assembling safety loading coefficient is high.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention,
All any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
