Abstract

The utility model relates to a building tool which provides a hand-held electric rubber gun which is a tool used in arranging paste sealing strips between the glass and a frame of a door window and is shaped like a gun, wherein, a rubber cylinder 5 is arranged in a front end of a gun barrel 3; a piston 7 and a piston rod 8 with racks 9 are arranged at the back of the rubber cylinder 5 and are driven to work by a trigger 2. The hand-held electric rubber gun is developed to solve the problem that the trigger 2 has no continuous promoting movements and the triggering direction of the trigger 2 is opposite to the direction of the paste coating, which results in irregular thinness and thickness of the extruded rubber bars and difficult operation. The utility model is characterized in that a micro motor 11, a gearbox 12 and a transmission gear 10 are arranged on the gun body, and the transmission gear 10 is meshed with the racks 9 of a piston rod and a switch of the micro motor 11 is connected with the trigger 2. As the piston can make continuous movements driven by the electric motor, the rubber bars are uniform in thinness and thickness and easy to be controlled, which can reduce the difficulty in operation and improve the working quality.

Description

Hand electric glue rifle

Affiliated technical field

The utility model relates to a kind of building implement, promptly a kind of hand electric glue rifle.

Background technology

The glue rifle is the instrument at dispensing paste sealing strip between the glass of door and window and the framework and on other slits, its agent structure shape such as pistol, the packing element of splendid attire glue cream can be assembled in the muzzle front, the packing element front opening, there is a piston at the rear portion in the tube, and piston rod is provided with tooth bar, tooth bar stretches into gun barrel backward, move forward under the drive of trigger, glue cream is discharged from front opening in the extrusion tube, forms adhesive tape.During work, the people holds pikestaff, and the packing element opening press close to is needed the slit of sealing, and button draws trigger repeatedly, promotes piston and moves ahead, and discharges adhesive tape, and mobile simultaneously muzzle can be coated with adhesive tape and is pressed on the slit.The problem that this glue rifle exists is: the propelling action of trigger can not be continuous, pull, and piston-advance one segment distance, subsequently, the trigger return is pulled next time again.Like this, will cause the reach action of piston to be interrupted, glue cream can not be extruded continuously, and particularly the action of cocking and the direction of action that is coated with moulding cream repeatedly causes the adhesive tape plucked of extruding, and is difficult to operation.

Summary of the invention

It is little that the purpose of this utility model provides a kind of operation easier, the hand electric glue rifle that operation quality is good.

Above-mentioned purpose is realized by following technical scheme: develop a kind of hand electric glue rifle, the main body shape such as the pistol of this glue rifle, pikestaff, trigger, gun barrel are arranged, the front end of gun barrel also can assemble packing element, also there is piston the packing element back and has the piston rod of tooth bar, and different is: on the rifle body, micromachine, gearbox and travelling gear are housed, gear is meshed with the tooth bar of piston rod, and the switch and the trigger of micromachine interrelate.

Adopt the hand electric glue rifle of technique scheme, what piston can be continuous under the drive of motor moves, and the adhesive tape even thickness of extruding is convenient to control, has reduced operation easier, has improved operation quality.

Description of drawings

Fig. 1 is the front view of a kind of embodiment;

Fig. 2 is the left view of this embodiment;

Fig. 3 is the vertical view of this embodiment.

Among the figure as seen: pikestaff 1, trigger 2, gun barrel 3, dop 4, packing element 5, opening 6, piston 7, piston rod 8, tooth bar 9, gear 10, micromachine 11, gearbox 12, switch 13, spring 14.

The specific embodiment

As shown in Figure 1, 2, 3, the shape of this glue rifle is also similar with pistol, pikestaff 1 is arranged, trigger 2, gun barrel 3, front end at gun barrel 3 has a dop 4, packing element 5 is contained on the dop 4, and the front end of packing element 5 also has opening 6, and there is a piston 7 back, tooth bar 9 is also arranged above the piston rod 8, and these are all very similar with existing glue rifle.Different is: the tooth bar 9 here is not direct and trigger 2 interrelates, but is meshed with a gear 10, and gear 10 interrelates by gearbox 12 and micromachine 11, and the switch 13 and the trigger 2 of micromachine 11 interrelate.The power supply of motor can be an alternating current, also can be battery.During work, cocking 2, switch 13 is connected, and micromachine 11 driven gears 10 rotate, and drive tooth bar and push ahead, and glue cream is extruded.When needs stop, unclamping trigger 2, trigger 2 is return under the pulling of spring 14, and switch 13 disconnects, and motor 11 stops.Tooth bar 9 here and gear 10 also can be made the profile of tooth of one way engagement, and tooth bar 9 can be with pulling back.Certainly, also can adopt reversing switch, the advance and retreat stroke by motor 11 drive tooth bars 9 also can be provided with limit switch on tooth bar 9, realizes automatic reverse and automatic start-stop.
