Abstract

The invention relates to a muffled axial powder-actuated tool. The muffled axial powder-actuated tool comprises a main body including a nail tube, and is characterized in that the nail tube is provided with a concave part, a muffling sleeve is arranged outside the nail tube, and a closed muffling space is formed between the concave part and the inner wall of the muffling sleeve. The muffled axial powder-actuated tool has the following beneficial effects: voice generated by powder loads which explode in the nail tube is conveyed to the muffling space by the nail tube, and in the muffling space, hindered by the muffling sleeve, so that the strength of voice conveyed to the environment is greatly reduced, a muffling and sound insulating function is achieved, ambient noise is effectively reduced, and accordingly, protection of body health of constructers is facilitated, and the conflict that construction disturbs residents is avoided.

Description

The axial screw shooter of muffling type

Technical field

The invention discloses a kind of nailing tools.

Background technology

Screw shooter is to utilize firing pin to produce gunpowder explosion in firing nail shooting pill, nail shooting pill to produce Thrust, as power, makes pinch bar motion and nailing is squeezed into the instrument of building body.

Existing screw shooter, its percussion lock principle is: firing pin passes through striker spring compress energy storage (now firing pin is hindered ferrum restriction).Then cocking, the seesaw of trigger promotes resistance ferrum, Under the thrust of spring, the free rapid reach of firing pin, front end impact nail shooting pill drain pan, Making nail shooting pill blast produce thrust, impact nailing by bucking bar, fulfil assignment task.

The percussion lock of existing screw shooter, trigger is all that design is before handle, it is necessary to use hands Plate moves, and such frame mode has the disadvantages that in use

1., during end face operation, such as when ceiling operation, workmen must use ladder Or scaffold, allows hands can reach the standard of screw shooter trigger position, could construct, it is obvious that Such work efficiency is extremely low, and the labor intensity of workmen is very big, also has Potential safety hazard.

2. during Ground Operation, workmen also must bend over to operate, long-term so work, The health of workmen also can be by chronic injury.

3. during the operation of side, it is sometimes desirable to the metope of construction, owing to landform limits or obstacle The existence of thing, also makes the workmen can not be close, there is also the situation of constructional difficulties equally.

In order to overcome above-mentioned technical defect, the applicant have developed and axially fires screw shooter (ZL 201520748109.3), moves original palm seesaw release firing pin mode and changes into The mode of axially-movable release firing pin, makes the operator can axial force distribution very easily Fulfil assignment, coordinate with extension rod, achieve remotely operation the most smoothly, thus overcome The originally disadvantage of necessary short-range operation.

Above-mentioned axial percussion screw shooter in use there is a defect: nail shooting pill Can produce huge noise at nail pipe internal explosion, this noise is directly transmitted by nail pipe In environment, site operation personnel are formed voice impact, also makes job site exist simultaneously The phenomenon disturbed residents.

Summary of the invention

It is an object of the invention to provide a kind of axial screw shooter of muffling type to make up prior art not Foot.

The present invention the technical scheme is that for realizing purpose

The axial screw shooter of muffling type, including main body, main body includes nail pipe, it is characterized in that: nail pipe On have recess, recess has through hole, nail pipe is outside equipped with noise reduction set, recess and noise reduction set inwall Form the silence space closed.

Optimize: described noise reduction set and the connected mode of nail pipe are threaded.

The beneficial effects of the present invention is: the nail shooting pill of blast in nail pipe, the voice of generation leads to The through hole crossed on nail pipe is delivered to silence space, is intercepted by noise reduction set, make in silence space The voice intensity that it is delivered in environment is greatly reduced, and serves the effect of sound-insulation, has Imitate reduces environment noise, is conducive to the personnel protection to workmen, it also avoid and execute The contradiction that work disturbs residents.

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

Accompanying drawing explanation

Fig. 1 is the structural representation of the embodiment of the present invention.

Fig. 2 is the parts decomposition texture schematic diagram of Fig. 1.

Fig. 3 is the schematic perspective view of Fig. 2.

Detailed description of the invention

Embodiment:

In the drawings: 1 is nail pipe, and 2 is noise reduction set, and 3 is movable sleeve, and 4 is striker post, and 5 are Firing pin assembly, 6 is percussion set, and 9 is braking dog chart, and 10 is protection set, and 12 is percussion key, 13 is to connect handle, and 15 is banking pin, and 16 is percussion set spring, and 17 is striker spring, and 18 is recessed Portion, bulge loop before 20,21 is rear bulge loop, and 22 is through hole.

There are front bulge loop 20, rear bulge loop 21 respectively before and after nail pipe 1, formed between two bulge loops Recess 18.External screw thread is had on front bulge loop 20.

Noise reduction is overlapped has female thread on front side of 2 inner circles, can be screwed on the external screw thread on front bulge loop 20, Assembling is realized, now: the rear end of noise reduction set 3 realizes with rear bulge loop 21 front end face after spinning Tight fit, so, recess 18 and noise reduction are overlapped 3 inwalls and are formed the silence space closed.

The use process of this screw shooter and mode have detailed retouching at ZL 201520748109.3 State, do not repeating at this.

When nail shooting pill explosion time in nail pipe 1, the voice of generation is by the through hole on nail pipe 1 22 are delivered to silence space, by noise reduction set 2 obstruct in silence space so that it is be delivered to ring Voice intensity in border is greatly reduced, and serves the effect of sound-insulation, effectively reduces Environment noise, is conducive to the personnel protection to workmen, it also avoid the lance that construction disturbs residents Shield.

Claims

1. the axial screw shooter of muffling type, including main body, main body includes nail pipe, it is characterized in that: nail There is recess on pipe, recess has through hole, nail pipe are outside equipped with in noise reduction set, recess and noise reduction set Wall forms the silence space closed.

The axial screw shooter of muffling type the most according to claim 1, is characterized in that: described Noise reduction set and nail pipe connected mode be threaded.
