Abstract

The utility model discloses a fuel gas nailing tool which comprises a shell body (1), a gun head (2), a gun barrel (3), an insurance holder compressed spring (4) and an insurance support (5). The gun head (2) is connected with the front end of the shell body (1) through a circular disc (6). The gun head (2) and the gun barrel (3) are in a split type. One end of the gun barrel (3) penetrates through the inside of the gun head (2), anti-rotation is achieved through an anti-rotation device, and the insurance holder compressed spring (4) and the insurance support (5) are both connected at the one end of the gun barrel (3). The fuel gas nailing tool has the advantages of being ingenious in structural design, easy to manufacture and install, capable of not only obtaining large enough hitting force, but also being wide in range of application under the condition that the length of the shell body is not added, low in nailing cost, and capable of saving using cost greatly.

Description

A kind of combustion gas nailing instrument

Technical field

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

Background technology

At present, existing combustion gas nailing instrument mainly comprises housing 1, cylinder head, cylinder sleeve combination, cylinder block, piston striker combination, the rifle head 2 with gun barrel, volute spring, guard, push rod and trigger handle, the combustion gas nailing instrument of this spline structure, abdicate installing space in order to give the guard stage clip, in the situation that does not change shell length, just must shorten the length (such as Fig. 1) of cylinder block, do like this, caused the total kilometres of piston striker greatly to shorten, so that nailing strength has reduced more than 10%.In order to obtain enough nailing strength, abdicate installing space can for again simultaneously the guard stage clip, many producers just adopt the method that prolongs shell length to realize (such as Fig. 2), but, do like this and can cause the overall length of combustion gas nailing instrument to lengthen at least 20mm, 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, with the guard stage clip be arranged on housing outer after, its guard just is arranged on the gun barrel, do like this and not only make relative complex, and consumptive material is more, cause cost to increase, and, the combustion gas nailing instrument of this spline structure can't impact the bar for line for fastening thermal insulation wall surface because gun barrel is subject to 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.

The utility model content

The purpose of this utility model just provides the combustion gas nailing instrument that a kind of hitting dynamics is large, the scope of application is wide.

The purpose of this utility model is to realize by such technical scheme, a kind of combustion gas nailing instrument, comprise housing, rifle head, gun barrel, guard stage clip and insurance support, described rifle head is connected with the front end of housing by disk, described rifle head and gun barrel are split type, one end of described gun barrel penetrates in the rifle head and by the anti-rotation device anti-rotation, described guard stage clip and insurance support all are connected to this end.

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

Owing to adopted technique scheme, the utlity model has the ingenious manufacturing of structural design simple advantage is installed, adopt it in the situation that does not increase shell length, it is large not only can to obtain enough hitting dynamics, and the scope of application is larger, and nailing is with low cost, has greatly saved use cost.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.

Embodiment 1: shown in Fig. 3,4,5, a kind of combustion gas nailing instrument, comprise housing 1, rifle head 2, gun barrel 3, guard stage clip 4 and insurance support 5, described rifle head 2 is connected with the front end of housing 1 by disk 6, described rifle head 2 is split type with gun barrel 3, one end of described gun barrel 3 penetrates in the rifle head 2 and by the anti-rotation device anti-rotation, described guard stage clip 4 and insurance support 5 all are connected to this end.

Further describe, described 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 open slot 8 on the described rifle head 2, described boss 7 is positioned at open slot 8, one end of described guard stage clip 4 is connected with screw and is connected with boss 7 by spring base 9, the other end is connected with disk 6, and are connected with boss by screw 10 and spring base 9 and are connected between spring base 9 and boss 7 in described insurance support 5 bottoms.

Such structure is installed simply so that make, and consumptive material is also less, has reduced the cost of making.

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

In the utility model, gun barrel 3 can be mobile vertically in rifle head 2, 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 utility model, not only can hit common securing member, and because gun barrel 3 has substituted guard, be not subject to the restriction of guard, bar for line can 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, for existing nailing instrument for hitting bar for line, the utility model adopts combustion gas to act as a fuel, and greatly reduces cost, calculates according to reality, every dozen of bar for lines only need 0.03 yuan.
