Abstract

The invention relates to a length-adjustable nail pipe applied to a nail shooting device. The length-adjustable nail pipe is characterized in that a front hollow part and a back hollow part are included and connected through a thread; the front part is sleeved with the back part; the wall of the back part is sleeved with a sliding sleeve, a spring is arranged between the sliding sleeve and the back end of the back part, and a stop part is arranged at the front end of the back part; holes are formed in the wall of the back part, and balls are arranged in the holes; grooves are formed in the inner wall of the front end of the sliding sleeve; rotation stopping grooves are formed in the outer wall of the front part. The length-adjustable nail pipe has the advantages that due to the fact that the length of the nail pipe can be adjusted through the separated design, the stress stroke of a shot nail is changed, the degree that the shot nail is driven into a base body is effectively controlled, different requirements needed in actual operation are met, the structure is simple, the working reliability is high, the service life is long, the application range is wide, and all nail pipes applied to similar nail shooting devices at the present stage can achieve the functions after being improved.

Description

It is applied to the length adjustable nail pipe on screw shooter

Technical field

The invention discloses a kind of nail pipe, it is especially suitable for the depth that adjustment nailing squeezes into matrix.

Background technology

Screw shooter is the fastening tool commonly using at this stage, and its cardinal principle is: firing pin impact nail shooting pill is so as to quick-fried The blast of fried room, air stream drives piston rod quickly moves forward, and in impact nail pipe, preset nailing, makes nailing be pushed in matrix.

In existing structure, the stroke of bucking bar fix, follow closely the consistent length of pipe, nailing installation site identical, this After sample will make to fire every time, the length that nailing hammers into matrix is on all four.

But in actual use, often to need to adjust the length that nailing hammers into matrix according to different use environments, Such as it is sometimes desirable to nailing be hammered into matrix completely it is sometimes desirable to nailing only be hammered into 1/2 length enter matrix.

Above-mentioned requirements, rely on existing technology cannot realize.

Our improved though is: using existing screw shooter primary structure, makes structural improvement, makes nail length of tube Realize adjustable, thus meeting actual demand.

Content of the invention

It is an object of the invention to provide a kind of length adjustable nail pipe being applied on screw shooter is to make up prior art not Foot.

The present invention is to realize purpose the technical scheme is that

It is applied to the length adjustable nail pipe on screw shooter, it is characterized in that: include the former piece of hollow and the consequent of hollow, front It is threaded connection between part and consequent；

Consequent is enclosed within outside former piece；

It is cased with sliding sleeve outside consequent wall, between sliding sleeve and consequent rear end, is provided with spring, consequent front end is provided with block piece；Consequent Hole is provided with wall, in the hole has ball；Fluted in sliding sleeve front inner wall；

Rotation stop groove is had on former piece outer wall.

Optimize: when described sliding sleeve movement is to rear position-arresting, groove location is corresponding with ball position；Hole is tapered hole, its Internal orifice is osculum.

Optimize: described rotation stop slot number amount is 2 and more than 2, and along the circumferential direction uniform；Hole and the number of rotation stop groove Amount is identical.

The beneficial effects of the present invention is: using the design of split, can be with the length of adjustment nail pipe, thus change penetrating Nail by force-stroke, be effectively controlled the degree that nailing hammers into matrix, meet different demands during actual job, its structure Simply, functional reliability is strong, long service life, and applied widely, the nail pipe of similar screw shooter at this stage is transformed, all Above-mentioned functions can be completed.

Below by embodiment, and the invention will be further described to combine accompanying drawing.

Brief description

Fig. 1 is structural representation during embodiment of the present invention naturalness (rotation stop lock-out state).

Fig. 2 is structural representation when rotating adjustment length.

Fig. 3 is the exploded sketch of Fig. 1.

Fig. 4 be nailing hammer into matrix deeper when structural representation.

Fig. 5 be nailing hammer into matrix shallower when structural representation.

Specific embodiment

In in figure: 1 is former piece, 2 is consequent, and 3 is screw thread, and 4 is sliding sleeve, and 5 is spring, and 6 is block piece, and 7 is tapered hole, and 8 are Ball, 9 is turn trough till groove, 10, and 11 is nailing, and 12 is bucking bar, and 13 is matrix.

Embodiment:

Natural lock-out state:

Former piece 1 and consequent 2 are realized connecting by the cooperation of screw thread 3, form overall nail pipe, nail pipe is built with nailing 11.

Because former piece 1 and consequent 2 are connected by screw thread 3, so certainly needing anti-rotation structure in operation, now Anti-rotation structure is as follows: ball 8 is located in the tapered hole 7 on consequent wall, and the outer imperial palace of tapered hole 7 is little, and the diameter of endoporus is less than ball 8 Diameter, so that ball 8 is will not fall in it, ensure that ball 8 has certain overhang in interior in the hole simultaneously again.This overhang falls Enter in the rotation stop groove 10 on former piece 1 outer wall.

State now: the outside of ball 8 is limited by the inwall of sliding sleeve 4, inside is limited by rotation stop groove 10, thus effectively The rotation preventing former piece 1 and consequent 2, be easy to Launch Operation.

Generating process is similar with conventional screw shooter, bucking bar 12 under the driving of the explosion energy of nail shooting pill, quick before Move, nailing 11 is squeezed in matrix 13.

Adjustment state:

When the length needing to adjust adjustable nail pipe it is possible to by rotating the screw thread 3 between former piece 1 and consequent 2, change Become the silk number of screw thread cooperation, and before this, need to unlock: the elastic force that sliding sleeve 4 is overcome spring 5 backward moves, Groove 9 also moves after the meeting, and is eventually located at the position of ball 8, and keeps this state.

Now, the outside locking of ball 8 just can release, and rotates former piece 1 and consequent 2, and ball 8 is outer to be moved, and falls into the sky of groove 9 Interior, rotational action would not be hindered.

After turning to appropriate length, when ball 8 is again positioned at the position of rotation stop groove 10, discharge sliding sleeve 4, sliding sleeve 4 is in spring 5 The lower reach of elastic force effect reset (block piece 6 carries out front limit to sliding sleeve 4), when ball 8 falls into the position of rotation stop groove 10 again, this When the no longer corresponding ball 8 of groove 9 position, form lock-out state again.

Rotation stop groove 10, tapered hole 7, the quantity of ball 8 are consistent, can be arranged different according to the precision of adjustment length Quantity.

The meaning of adjustment nail length of tube in: change nail pipe front end and bucking bar front end distance, to meet different nailings Inject the requirement of body depth, effect just can significantly be found out from Fig. 4 and Fig. 5.

Alternatively, it is also possible to arrange screw on consequent 2 wall, screw is set in screw, is screwed in using screw, its front end is supported Live the outer wall of former piece 1, realize rotation stop, such design is convenient apparently without the present invention, adjustment every time is required for using instrument, relatively For loaded down with trivial details.
