Technical Field

The utility model relates to a construction equipment technical field, concretely relates to piston rifle of gluing.

Background

In the fields of building decoration and the like, glue guns are generally adopted to glue occasions needing gluing. Manual, pneumatic and electric glue guns are mainly used in the prior art. The pneumatic glue gun is powered by compressed gas, the bottom of the glue is pushed by the pressure of the gas to realize glue pushing, and the compressed gas can be compressed air generally. The amount of glue discharged can be controlled by adjusting the air pressure.

However, in actual operation, when the hot melting temperature is insufficient or the ambient temperature is low, the glue discharge easily blocks the nozzle of the gun head.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can prevent rifle head jam, can glue solution cyclic utilization's piston gluey rifle.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a piston type glue gun comprises a gun body, a trigger and a handle are arranged outside the gun body, the gun head penetrates through the inside and the outside of the gun body, the piston type glue gun also comprises a pressure cavity, a heating device, a glue outlet channel, a linkage assembly and a piston, the pressure cavity is arranged inside the gun body and is connected with the heating device, and the pressure cavity is connected with the gun head through the glue outlet channel; the piston is arranged below the glue outlet channel and is connected with the glue outlet channel; the linkage assembly inside the gun body is movably connected with the trigger and the piston respectively; the junction of the piston and the glue outlet channel forms a storage cavity.

Further, the width of the connecting end of the glue outlet pipeline and the pressure cavity is larger than that of the connecting end of the gun head. The glue solution is prevented from overflowing due to overlarge pressure, and the glue yield is controlled.

Still further, the linkage subassembly includes push rod and connecting rod, and one end and the trigger swing joint of push rod, the other end and the connecting rod swing joint of push rod, push rod and connecting rod mutually perpendicular, connecting rod and piston connection.

Furthermore, the linkage assembly further comprises a positioning piece, and the positioning piece is connected with the push rod in a matched mode to limit the movement position of the linkage assembly. When the user operates, the glue outlet amount can be controlled by controlling the position of the trigger.

Still further, the rifle head is connected with detachable nozzle. The nozzles with different sizes can be replaced according to actual needs.

The utility model discloses a theory of operation:

the adhesive tape becomes the melting wire-drawing state after being heated by the heating device, a user presses the trigger downwards to drive the lower end of the push rod to move leftwards, so that the upper end of the push rod moves rightwards, the connecting rod and the piston move rightwards, the pressure cavity is driven to press the adhesive liquid in the melting state into the adhesive outlet channel, the adhesive outlet amount is controlled according to the force for pressing the trigger, the trigger is loosened after the adhesive outlet is finished to enable the piston to return to the original position, the piston is in a vacuum state at the moment, and the adhesive liquid retained in the gun head is siphoned to the storage cavity. When the trigger is pressed next time to drive the piston to push leftwards, the glue solution stored in the storage cavity is pushed out of the storage cavity by the pressure generated by the motion of the piston and returns to the glue outlet channel.

The utility model has the advantages of:

1. the storage cavity sucks or discharges the glue solution retained in the glue outlet channel by means of pressure difference caused by movement of the piston, so that the nozzle of the gun head is prevented from being blocked, and the glue solution can be circulated and reflowed to the glue outlet channel.

2. The glue output can be controlled by combining the force of pressing the trigger and the selected nozzle size.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the following embodiments are based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the embodiments.

The utility model provides a piston glue gun, including the

rifle body

1, 1 outside trigger 2 and the handle 3 of being provided with of the rifle body, rifle head 4 runs through inside and outside the rifle body 1, still include pressure chamber 5, a heating device, go out gluey passageway 6, linkage assembly and

piston

10, 1 inside pressure chamber 5 that is provided with of the rifle body, pressure chamber 5 is connected with heating device, pressure chamber 5 is connected with rifle head 4 through going out gluey passageway 6, piston 10 sets up in the below of going out gluey passageway 6 and is connected with play

gluey passageway

6, 1 inside linkage assembly of the rifle body respectively with trigger 2 and piston 10 swing joint, piston 10 forms storage chamber 7 with the junction of going out gluey passageway 6.

Further, the width of the connecting end of the glue outlet pipeline 6 and the pressure cavity 5 is larger than that of the connecting end of the glue outlet pipeline and the gun head 4. The glue solution is prevented from overflowing due to overlarge pressure, and the glue yield is controlled.
