Abstract

The invention discloses a gas nailing tool. The gas nailing tool comprises a shell (1), a gun head (2), a gun barrel (3), a safety support pressure spring (4) and a safety support (5). The gun head (2) is connected with the front end of the shell (1) through a disk (6), the gun head (2) and the gun barrel (3) are split, and the safety support pressure spring (4) and the safety support (5) are both connected to one end of the gun barrel (3) which penetrates into the gun head (2) and is prevented from rotating through a rotation preventing device. The gas nailing tool has the advantages of ingenious structural design and simplicity in manufacturing and mounting, using the gas nailing tool without increasing the length of the shell can not only obtain enough striking force but also realize wider utilization range and low nailing cost, and utilization cost is greatly saved.

Description

A kind of combustion gas nailing instrument

Technical field

The present invention relates to a kind of instrument of at combustion chambers burn driven plunger striker securing member being squeezed into working face by liquefied gas through the electric shock discharge.

Background technology

At present, existing combustion gas nailing instrument mainly comprises rifle head 2, volute spring, guard, push rod and the trigger handle of housing 1, cylinder head, cylinder sleeve combination, cylinder block, the combination of piston striker, the pipe that carries a gun, the combustion gas nailing instrument of this spline structure; Abdicate installing space in order to give the guard stage clip; Under the situation that does not change shell length, just must shorten the length (like Fig. 1) of cylinder block, do like this; Cause the total kilometres of piston striker to shorten greatly, made nailing strength reduce more than 10%.In order to obtain enough nailing strength; Abdicate installing space can for again simultaneously the guard stage clip, many producers realize (like Fig. 2) with regard to adopting the method that prolongs shell length, still; Be the overall length that can the cause combustion gas nailing instrument 20mm that extends at least like this; Not only increased manufacturing cost, and the beat about easy the generation rocks in the operating process of nailing, causes nailing inaccurate.In order to solve above-mentioned defective, many producers take that the guard stage clip is arranged on the outer method of housing and solve, still; After being arranged on the guard stage clip outside the housing, its guard just is arranged on the gun barrel, does like this and not only makes relative complex; And consumptive material is more, causes cost to increase, and; The combustion gas nailing instrument of this spline structure can't impact the bar for line that is used for fastening thermal insulation wall surface because gun barrel receives the restriction of guard, has dwindled the scope of application.

In order to hit bar for line, some producer has just made the nailing instrument that can hit bar for line specially, but such nailing instrument is to adopt gunpowder to act as a fuel; In the nailing process, gunpowder causes insulation material burning, breaking out of fire easily; Simultaneously; Utilize gunpowder to act as a fuel, every dozen of nails need 0.24 yuan, cause cost higher.

Summary of the invention

The object of the invention just provides the combustion gas nailing instrument that a kind of hitting dynamics is big, the scope of application is wide.

The objective of the invention is to realize through such technical scheme; A kind of combustion gas nailing instrument; Comprise housing, rifle head, gun barrel, guard stage clip and insurance support, said rifle head is connected with the front end of housing through disk, and said rifle head and gun barrel are split type; One end of said gun barrel penetrates in the rifle head and through the anti-rotation device anti-rotation, said guard stage clip all is connected this end with the insurance support.

Wherein, Said anti-rotation device is to be arranged on the boss on the gun barrel one end outer wall and to be arranged on the open slot on the said rifle head; Said boss is positioned at open slot, and an end of said guard stage clip is connected with boss with screw through spring base, and the other end is connected with disk; Said insurance frame bottom and is connected with boss with spring base through screw between spring base and boss.

Because having adopted technique scheme, the present invention to have the ingenious manufacturing of structural design installs simple advantage, adopts it under the situation that does not increase shell length; It is big not only can to obtain enough hitting dynamics; And the scope of application is bigger, and nailing is with low cost, has practiced thrift use cost greatly.

The specific embodiment

Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention, but the present invention is not limited to these embodiments, any on the present embodiment essence spirit improvement or substitute, still belong to claim of the present invention scope required for protection.

Embodiment 1: like Fig. 3,4, shown in 5; A kind of combustion gas nailing instrument; Comprise housing 1, rifle head 2, gun barrel 3, guard stage clip 4 and insurance support 5, said rifle head 2 is connected with the front end of housing 1 through disk 6, and said rifle head 2 is split type with gun barrel 3; One end of said gun barrel 3 penetrates in the rifle head 2 and through the anti-rotation device anti-rotation, said guard stage clip 4 all is connected this end with insurance support 5.

Further describe; Said anti-rotation device is to be arranged on the boss 7 on the gun barrel 3 one end outer walls and to be arranged on the open slot 8 on the said rifle head 2; Said boss 7 is positioned at open slot 8, and an end of said guard stage clip 4 is connected with boss 7 with screw 10 through spring base 9, and the other end is connected with disk 6; Said insurance support 5 bottoms and are connected with boss 7 with spring base 9 through screw 10 between spring base 9 and boss 7.

Such structure makes to make and installs simply that consumptive material is also less, has reduced the cost of making.

The present invention uses like this: securing member is packed in the gun barrel 3, and then with gun barrel 3 contact working faces and depress, cocking is squeezed into working face with securing member and is got final product then.

In the present invention, gun barrel 3 can move in rifle head 2 vertically, and simultaneously, boss 7 has played the rotation of restriction gun barrel 3 at circumferencial direction, and the boss 7 of gun barrel 3 can move up and down in open slot 8 vertically.

In the present invention, not only can hit conventional fastener, and, not receive the restriction of guard because gun barrel 3 has substituted guard; Can bar for line be installed in and carry out strike work on the gun barrel 3, the scope of application is more extensive than existing nailing instrument, simultaneously; To the existing nailing instrument that is used to hit bar for line, the present invention adopts combustion gas to act as a fuel, and greatly reduces cost; According to the reality measuring and calculating, every dozen of bar for lines only need 0.03 yuan.
