Description

Nail shooter launching tube assembly

Technical Field

The utility model relates to the technical field of nail shooters, in particular to a nail shooter launching tube assembly.

Background

The nail shooter uses the solid double-base medicine or the single-base medicine as energy, after the solid double-base medicine or the single-base medicine is fired, high-temperature and high-pressure gas is generated to push the nail to be shot out or the nail to be shot into the hard component or the hard matrix through the piston to finish the fastening operation, but in the using process, the phenomenon that the shooting tube assembly of the nail shooter is damaged due to improper use exists, for example, the nail shooter is used on the soft matrix, or the energy with high power is used on the matrix with lower hardness, in the using modes, because the impact force generated after the solid double-base medicine or the single-base medicine is fired cannot be relieved collectively, the impact is released on the shooting tube assembly of the nail shooter, the damage of the nail shooter is caused, the subsequent construction operation is influenced even if the damage of the nail shooter is not caused, and the service life of the nail shooter is also influenced in the using process, the problems of clamping stagnation of the nail shooter, piston fracture and the like are caused, and the maintenance cost is greatly improved.

In view of this, the present application is specifically made.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a nailer firing tube assembly that reduces the impact force of a blow on a less hard substrate.

The utility model is realized by the following technical scheme:

a nail shooter launching tube assembly comprises a launching tube, wherein a nail tube sleeve is arranged at the front end of the launching tube, a slidable nail tube is inserted into the nail tube sleeve and the launching tube, a boss is arranged on the side surface of the nail tube and positioned between the nail tube sleeve and the front end of the launching tube, and a cushion pad is arranged between the boss and the nail tube sleeve; the inside cavity of the launching tube is also inserted with a slidable piston piece, and the piston piece comprises a front piston section which can be inserted into the nail tube and a tail piston section which can push the nail tube to advance.

The front end refers to the ejection direction of the ejection nail, the front end refers to one end of each part pointing to the ejection direction of the ejection nail, and the tail end refers to one end of each part back to the ejection direction of the ejection nail. According to the scheme, a nail is placed into a tube inner cavity of a nail tube, when a nail shooter is triggered, the tail end of a piston piece moves forwards under the action of thrust, the front section of the piston penetrates into the tube inner cavity of the nail tube to eject the nail, the tail end of the piston pushes the nail tube to move forwards, the nail tube prevents the piston from ejecting from the nail tube, and the nail tube is pushed by the tail end of the piston to extrude a boss on a buffer pad so as to reduce impact force. In the process, the piston firstly transmits the impact force to the nail tube, and then the impact force is reduced through the cushion pad, so that the impact force of the piston is well buffered, the service life of the cushion pad is prolonged, and the service life of the nail shooter is also prolonged.

Preferably, the boss and the buffer pad are both in annular structures surrounding the side face of the nail tube.

Through the annular structure, the buffering effect of the buffering cushion is enhanced, and the damage of the lug boss caused by overlarge impact force is avoided.

Preferably, the tail end of the nail tube is provided with a reducing section, a reducing through hole which gradually reduces in diameter along the direction from the tail end to the front end of the nail tube is formed in the reducing section, and the reducing through hole is communicated with the tube cavity of the nail tube; the front end of the tail section of the piston is provided with a reducing table matched with the reducing through hole, and the front end of the reducing table is connected with the tail end of the front section of the piston.

When the piston piece passes through the nail pipe, the surface of the reducing table is attached to the inner wall surface of the reducing through hole, so that the pushing area of the piston piece to the nail pipe is enlarged, the extrusion pressure of the piston piece to the nail pipe is reduced, and the rigid damage between the nail pipe and the piston piece under the impact force is reduced.

Further preferably, a gap exists between the outer side wall of the reduced diameter section and the inner side wall of the launching tube end.

Through the clearance ensures under the impact force, the reducing platform striking is in when on the reducing through-hole, can not lead to the lateral wall of reducing section to support and lean on because nail pipe end produces certain deformation on the terminal inner wall of launching tube, cause the jamming.

Further preferably, the length of the front piston section is greater than the length of the inner cavity of the nail tube.

Because the length of the front piston section is larger than that of the pipe cavity of the nail pipe, when the piston piece is inserted into the nail pipe, the front end of the front piston section extends out of the front end of the nail pipe and is impacted on a fastened base body comprising a soft base body, a part of impact force is released to the fastened base body, and the damage of the part of impact force to the nail shooter can also be reduced.

Preferably, the front end of the transmitting tube is provided with a thread section, and the thread section is in threaded connection with the nail tube sleeve, so that the nail tube sleeve can be taken down conveniently to replace internal components.

Further preferably, the tail end of the threaded section is provided with a limiting surface for limiting the nail pipe sleeve to move towards the tail end of the launching pipe.

In the process that the nail pipe sleeve is connected with the launching tube through threads, the limit surface limits the nail pipe sleeve to be excessively deep, and the buffer effect of the buffer cushion is prevented from being weakened due to the fact that the buffer cushion is excessively extruded by the nail pipe sleeve due to the fact that the nail pipe sleeve is deep. Preferably, when the nail pipe sleeve is attached to the limiting surface, the distance between the bottom surface of the cavity in the nail pipe sleeve and the transmitting pipe is equal to the sum of the widths of the lug boss and the buffer pad in a loose state.

2. according to the nail shooter launching tube assembly provided by the embodiment of the utility model, the pushing area of the piston piece to the nail tube is enlarged through the matching of the reducing section and the reducing table, so that the extrusion pressure of the piston piece to the nail tube is relieved, and the rigid damage between the nail tube and the piston piece under the impact force is reduced;

3. according to the nail shooter launching tube assembly provided by the embodiment of the utility model, the gap is arranged between the outer side wall of the reducing section and the inner side wall of the tail end of the launching tube, so that under the impact force, even if the reducing table impacts on the reducing through hole to cause certain deformation of the tail end of the nail tube, no clamping stagnation is caused, and the use reliability of the device is ensured;

4. according to the nailing device launching tube assembly provided by the embodiment of the utility model, the axial length of the front piston section is larger than that of the inner cavity of the nail tube, the front end of the front piston section can extend out of the front end of the nail tube and hit a fastened substrate comprising a soft substrate, and a part of impact force is released to the fastened substrate, so that the damage of the part of impact force to the nailing device can be reduced.
