Description

Ail shooter

The utility model relate to a kind of in fields such as decorations, project installation the widely used ail shooter of object being installed, being connected and installed object that is used for fixing.

Existing ail shooter structure is complicated, the dismounting inconvenience, in use, the operating air pressure that enters piston cylinder that the nail shooting pill outburst is produced can not be regulated, therefore, when operation, when running into the matrix of different hardness or the conversion of nailing length, then need change the model of nail shooting pill, this makes troubles to constructing operation.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and adjustable, the simple in structure easy-to-mount ail shooter of air pressure that provides a kind of nail shooting pill blast to produce.

The purpose of this utility model can reach by following measure: the utility model includes an outer sleeve body, the fastening handgrip that is equipped with below this outer sleeve body, one plate machine is installed on this handgrip, at outer sleeve body inner chamber rear portion one firing pin is installed, at the piston cylinder inner chamber one piston rod is installed, it is characterized in that being connected into one at anterior piston cylinder of installing of outer sleeve body inner chamber and nail pipe; Be manufactured with a screw that communicates with the piston cylinder inner chamber at this piston cylinder afterbody, in this screw, be fitted with a bolt, on this piston cylinder, be manufactured with some radiating grooves that interlink with screw; One control valve that passes outer sleeve body and piston barrel is installed in the outer sleeve body front portion.

Fig. 1 is the utility model complete section structural principle schematic diagram

Fig. 2 is the 1. local enlarged diagram of screw among Fig. 1

The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: shown in Figure 1,4 is outer sleeve body, the fastening handgrip 6 that is equipped with below this outer sleeve body 4, one plate machine 7 is installed on this handgrip 6, at outer sleeve body 4 inner chamber rear portions one firing pin 8 is installed, at piston cylinder 2 inner chambers one piston rod 16 is installed, be connected into one at anterior piston cylinder of installing 2 of outer sleeve body 4 inner chambers and nail pipe 3, be manufactured with a screw 1 that communicates with piston cylinder 2 inner chambers 14 at these piston cylinder 2 afterbodys, shown in Figure 2, in this screw 1, be fitted with a bolt 15, on this piston cylinder 2, be manufactured with some radiating grooves 9 that interlink with screw 1, one control valve 5 that passes outer sleeve body 4 and piston barrel 2 is installed in outer sleeve body 4 front portions, the designed ail shooter that provides of the utility model so just has been provided, the utility model operation principle is as follows: before using the ail shooter construction operation, some the nail shooting pills (not drawing among the figure) of in handgrip 6 inner chambers 10, packing into, manage the nailing (not drawing among the figure) of packing in 3 endoporus 12 at nail, during operation, nail pipe 3 front ends aligning is treated fixing or object to be connected, pull the plate machine 7 on the handgrip 6, the firing pin 8 that then is loaded on outer sleeve body 4 inner chamber rear portions clashes into the nail shooting pill that is positioned at its front end under dynamic action, and nail shooting pill is exploded, the high pressure gas that the nail shooting pill blast produces enters piston cylinder 2 inner chambers 14 from the pore 13 of piston cylinder 2 tail ends, this moment, bolt 15 was in the state of closing, high pressure gas to 14 li of piston cylinder 2 inner chambers does not produce discharging, this high pressure gas and then promotion are installed on piston rod 16 works done of piston cylinder 2 inner chambers will follow closely the nailing ejaculation of managing in 3 endoporus 12, make and treat that mounting article is fixed or object to be connected is connected and fixed, when treating fixing or to wait to connect the object matrix softer, or nailing more in short-term, then the required promotion emission air pressure of nailing will reduce, at this moment, bolt 15 rotations equipped in the screw 1 with piston cylinder 2 afterbodys are in loosening state, be that exhaust screw 1 is in semi-open state, because this screw 1 communicates with piston cylinder 2 inner chambers 14, and interlink with some radiating grooves 9 of making on the piston cylinder 2, like this, the high pressure gas that enters 14 li of piston cylinder 2 inner chambers that the nail shooting pill blast produces during the ail shooter operation, will discharge through radiating groove 9 from the screw 1 and the gap location of bolt 15, cause the air pressure of 14 li of piston cylinder 2 inner chambers to descend, to reach the air pressure that operation needs.Therefore, regulate the tightness of bolt 15, just can realize the air pressure of nail shooting pill blast generation is just regulated.When needs are dismantled, unclamp control valve 5 and withdraw from downwards, then nail pipe 3, piston cylinder 2 can be taken out in the lump, to its keep in repair, work such as cleaning, keep in repair, clean out, in its outer sleeve body 4 of packing in the lump, upwards tighten control valve 5, can carry out construction operation.

The utility model has following advantage compared to existing technology:

1, owing to be manufactured with a screw that communicates with the piston cylinder inner chamber at the piston cylinder afterbody, Be fitted with a bolt in this screw, and this screw communicates with some radiating grooves on the piston cylinder Connect, therefore, the tightness of adjusting bolt can be realized the height that blast produces to nail shooting pill The discharging of air pressure reaches to regulate and reduces operating air pressure, adapts to the work of different soft and hard work matrix Industry needs.

2, because piston cylinder and nail pipe are joined together, make simple in structurely, and a control valve that passes outer sleeve body and piston barrel is installed in the outer sleeve body front portion, therefore, when withdrawing from control valve downwards, nail pipe and piston cylinder can be taken out in the lump, like this, dismounting, maintenance, cleaning are all very convenient.
