Abstract

The utility model relates to a nail shooting device provided with a nail pipe sleeve. A nailing rod is arranged in a piston body, the front end of the piston body is connected with the nail pipe sleeve by virtue of a screw thread, a nail pipe is arranged in the nail pipe sleeve, and a thick part is arranged at the rear part of the nail pipe; a scrap containing circular groove is arranged on excircle of the rear end of the piston body; the front end of the piston body is an internal thread, the rear end of the nail pipe sleeve is an external thread, the internal thread and the external thread are matched, and a backstop bench is formed in the inner wall of the piston body. The nail shooting device provided with the nail pipe sleeve has the beneficial effects that the nail pipe sleeve is creatively designed as a connecting component, and the original hard nail pipe connection type is changed; when an abnormal working condition appears, a substrate is excessively soft, and a forward moving stroke of the nailing rod is large, only an impact force is formed to the nail pipe, and no powerful action is produced to the nail pipe sleeve; a connecting thread is not formed in the nail pipe (the nail pipe sleeve), so that a weak thread connecting part is effectively protected, the phenomenon that a component, which can be damaged most easily, of a complete machine is completely eradicated, service life of the complete machine is prolonged, and use cost is reduced.

Description

The ail shooter of band nail pipe box

Technical field

The utility model discloses a kind of nailing tools.

Background technology

Ail shooter is to utilize firing pin percussion nail shooting pill, produces thrust that gunpowder explosion produces in nail shooting pill as power, and bar motion nailing is squeezed into to the instrument of building body makes to pinch.

Existing ail shooter, all to utilize the reach of bucking bar (in piston body) high-speed motion, contact and its strike is entered to matrix with the nailing (in the nail pipe) of front end, under normal circumstances, the stroke of pre-designed bucking bar and nailing enter the degree of depth of matrix, these two parameters coordinate, not there will be problem, but, when matrix, cross when soft, nailing will enter the more degree of depth, causes the stroke of bucking bar also to increase thereupon, the consequence of bringing like this is exactly: bucking bar can have impulsive force to nail pipe (end face), owing to following closely pipe and piston body, is to be threaded.So screw thread can be subject to the effect of this impulsive force, cause coupling part (piston body screw thread and nail gas thread) to be damaged, complete machine only abandons, and has greatly increased use cost.

In order to overcome this problem, the improvement before us is to be provided with buffer gasket on the nail end surfaces, makes buffer gasket produce distortion to reduce part of impact force, and the protection screw thread, although can play certain effect like this, do not address this problem thoroughly.

Summary of the invention

The purpose of this utility model is to provide a kind of reliable operation, part replacement band convenient, long service life is followed closely the ail shooter of pipe box to make up the prior art deficiency.

The utility model is to realize that the technical scheme that purpose adopts is: the ail shooter of band nail pipe box, comprise piston body, and bucking bar is arranged in piston body, it is characterized in that: at the piston body front end nail pipe box that has been threaded, the nail pipe is arranged in the nail pipe box, nail pipe rear portion is thick section.

Optimize: be provided with on the rear end cylindrical of piston body and hold the bits annular groove.

Optimize: the piston body front end is internal thread, and nail pipe box rear end is external screw thread, and internal thread and external screw thread coordinate, and the retaining stage is arranged in the piston body inwall.

Optimize: the retaining stage is arranged in the piston body inwall.

Optimize: after the nail pipe, be connected with buffering ring.

The beneficial effects of the utility model are: the creationary nail pipe box that designed of the utility model, as attaching parts, has changed the hard connecting mode of original nail pipe.When damage occurring, matrix is excessively soft, when bucking bar reach stroke is larger, only can impacts power to the nail pipe, and the nail pipe box be there is no to the effect of power.Due to connecting thread (on nail pipe box) not on the nail pipe, so effectively protected fragile threaded joints, thereby make complete machine hold flimsy parts most, stopped the damage phenomenon, extended the service life of complete machine, reduced use cost.

Below by embodiment, and by reference to the accompanying drawings the utility model is further described:

The specific embodiment

Embodiment 1:

Occupation mode of the present utility model and product in the past are similar, below only for our improvements emphasis, describe.

As shown in Figure 1 and Figure 2, before percussion, together with the internal thread 4 of the external screw thread 2 of nail pipe box 1 and piston body 3 is screwed in, and bucking bar 5 is placed in piston body 3, and nail pipe 6 is placed in nail pipe box 1.

Interior to skidding off from nail pipe box 1 for fear of nail pipe 6, therefore nail pipe 6 rear ends are set to thick section 7, the rear end face of nail pipe box 1 can stop the front end face of thick section 7.

Fig. 2 is the state before exciting.After exciting, bucking bar 5 moves forward rapidly, its head is hitting nail and is entering matrix, under normal circumstances, the front end face of bucking bar 5 can not put forth effort on the rear end face (between the rear end face of the front end face of bucking bar 5 and nail pipe 6, also having certain distance L) of nail pipe 6, that does not just more have impulsive force to nail pipe box 1, as shown in Figure 3.

Under abnormal condition (as shown in Figure 4), matrix is excessively soft, and bucking bar 5 can move forward more distance, when this distance moved is greater than L, the front end face of bucking bar 5 will be put forth effort on the rear end face of nail pipe 6 so, makes nail pipe 6 also can be subject to the effect of power.But, due to front end face and the substrate contact of nail pipe 6, nail pipe 6 these power that are subject to will pass on matrix.So nail pipe box 1 is to beginning to not being subject to the effect of impulsive force eventually, thereby external screw thread 2 and internal thread 4 just have been subject to protection.

Under present abnormal condition, even follow closely pipe 6, damage, just directly change and get final product, not think in the past equally, thread damage causes complete machine to be scrapped.

Retaining stage 8 in piston body 3 is going-back positions of restriction nail pipe 6.

Piston body 3 rear end covers have ejection cover 101, both coordinate shooting of the task that realizes, when reality is used, the chip produced due to the nail shooting pill blast can be present between the two, thereby the not in place or incoherent situation that resets that can cause resetting, and affects follow-up shooting, Given this, we have designed and have held bits annular groove 100 on the cylindrical of piston body 3, and chip will enter cell body in sliding process mutually so, thereby not there will be above-mentioned defect.

Embodiment 2:

Similar with embodiment 1, difference is to follow closely on pipe box 1 internal thread is set, and on piston body 3, is provided with external screw thread, apparent.Can complete the connection task equally.

In the present embodiment, piston body 3 inwalls can continue to arrange retaining stage 8, and (allowing the front end face of piston body 3 replace the function of retaining stage 8) can be set yet.

Embodiment 3:

Similar with embodiment 1 and embodiment 2; just for the further external screw thread 2 of protection nail pipe box 1 and the internal thread 4 of piston body 3; be provided with cushion pad 9 after nail pipe 6, even nail pipe 6 is advanced to the most extreme position, buffering ring pad 9 also can be out of shape to bear a part of impulsive force.
