Description

A electromotion silicon gun

The present invention relates to an electric silicone gun, and more particularly, to allow both young and old to easily use even a simple switch operation, and to minimize waste due to the ejection of silicon when the user wants to stop using the silicone. In addition, the pusher pushing the pressure plate of the silicon tube to the original state as soon as possible to reload the silicon tube as soon as possible to the electric silicone gun to maximize the efficiency of the work.

In general, the silicone gun is discharged and bonded by discharging the silicon filled in the tube so that it is blocked from the air when bonding various members, such as fixing the window frame to the window frame or fixing the chassis to the wall between the various building materials or holes Or sealing work equipment.

As shown in FIG. 1 in the prior art of such a silicon gun, the silicon gun 10 has a handle 13 is formed at the lower portion of the body 11, the front of the silicon container insertion hole 915 is inserted into the silicon container 1) Is formed. In addition, a pressure rod 17 is installed along the center portion of the silicon container insertion hole 15, and the pressure rod 17 is bent at one end thereof. It is formed in a disc shape (not shown) to be applied to the pressure bar 15, the other end is bent. The pressure bar 15 is provided with a pressure spring 19 through which the pressure bar 15 penetrates into an inner space thereof, and a latch 21 at an end of the pressure spring 19, that is, the opposite side of the silicon container insertion hole 915. ) Is formed.

On the other hand, the trigger 23 allows the trigger 23 to flow within a predetermined range around the center pin 25 provided on the upper portion of the handle 13, the end of the trigger 23 is the latch ( 21), when the trigger 23 is pulled and released, it is moved back by the pressure spring 23 to its original position.

The silicon injection process of the conventional silicon gun 10 configured as described above is as follows.

First, when the user grasps the handle 11 of the silicon injector 10 and pulls the trigger 23 with a finger, the trigger 23 rotates about the center pin 25 while the end portion thereof has the latch 21 described above. The force on the pressure bar 17 is moved forward. When the pressure bar 17 moves forward, the back of the silicon container 1 is pushed and pressed, and as much silicon as the pressure bar 17 is moved is injected from the silicon container 1. In this case, typically about 1 cm to move, because the length of the silicone container is about 23 cm is applied about 23 times the force.

On the other hand, the trigger 23 rotated around the center pin 25 is moved back to the rear end by the elasticity of the pressure spring 19, so that the trigger 23, the original state before pulling the trigger 23, the user triggers again To eject the silicon. When the pressure bar 15 is to be pulled back, the bent portion at the rear of the pressure bar 15 is pulled out.

Eventually, the user repeats this process in the work.

The conventional silicon injector 10 described above is used in a relationship in which the pressure bar 15 generates the force using the friction between the pressure bar 17 and the catch 21 by squeezing the trigger 23 with a hand. As a result, the pressure rods 17 were cut off a lot, so that the pressure rods 17 were not easily caught by the clamps 21, and thus the life was short.

In addition, as silicone is sprayed only by one grip, it is impossible to continuously work, and it is difficult to control the amount of silicon sprayed by applying silicon by applying force. There were a lot.

And when there is a lot of work or when working in the winter, the silicone hardens, and the grip of the hands increases a lot, which makes the worker feel a lot of fatigue. Problems such as not easy to occur.

In particular, people with small hands and relatively low grip strengths, such as children and women, had a number of difficulties when triggering.

An object of the present invention was devised to solve the above problems, and to provide an electric silicone gun that can be easily used by both young and old with a simple switch operation.

Another object of the present invention is to provide an electric silicon gun which can minimize the waste due to the ejection of silicon when the silicon is to be stopped during use.

It is still another object of the present invention to provide an electric silicone gun which is capable of maximizing the efficiency of work by returning the pusher pushing the pressure plate of the silicon tube to the original state as soon as possible and then loading the silicon tube as soon as possible. .

That is, the state is continuously operated without stopping the driving of the motor 610.

In the above state, as shown in FIG. 4, the pressing member 640 is pressed downward so that the driving body case 600 is guided by the guide part 700 to move downward while compressing the elastic spring 710. When the gear gear 310 and the gear 310 of the output gear 650 and the rack member 300 are released, and then the reverse switch 820 is turned on, the motor 610 is reversely rotated as shown in FIG. 5. As the reverse rotation, the rack member 300 is wound on the take-up roll 410 constituting the take-up means (400).

Here, the state of Figure 4 is a state in which the spring spring 420 is unwinded, and since the winding spring 420 is always wound to rotate the take-up roll 410, the rack member 300 is in a state that can be wound on the take-up roll 410. .

Subsequently, as shown in FIG. 5, when the button part 540 is reversed to remove the external force applied to the pressing part 530, the friction part 510 is spaced apart from the take-up roll 410.

So far, the basic operation of the present invention will explain the process of ejecting all the silicon is ejected without stopping once.

However, in some cases, only part of the silicon contained in the silicon tube 210 is used during the use of the silicon gun.

That is, as shown in FIG. 9, when the injection of the silicon is stopped when only part of the silicon is used, the reverse switch 820 is turned on to rotate the motor 610 in reverse, as shown in FIG. 9. While the silicon in the silicon tube 210 is partially used, the pusher 320 is retracted with the rack member 300 to move to its original position.

Then, the reversed rack member 300 is naturally wound by the spring spring 420 on the winding roll 410 of the winding means 400.

Therefore, the present invention can minimize the waste of silicon by lowering the residual pressure of silicon ejection as much as possible by removing the force pressurizing the pressure plate 212 of the silicon tube 210 as soon as possible to stop the ejection of silicon during use. Will be.

As described above, the present invention makes it easy for anyone, young and old, even with a simple switch operation, and minimizes the waste due to the ejection of silicon when the user wants to stop using the silicon. The pusher will return to its original position as soon as possible, allowing the silicon tube to be loaded as soon as possible, thus maximizing work efficiency.
