Description

Silicon gun

The present invention relates to a silicon gun, and more particularly, to a silicon gun that increases the discharge amount of a single operation lever by increasing the driving distance of the operation plate at the time of silicon launching with a simple structural change.

The silicon gun is used for the purpose of preventing leakage and bonding between materials and looks at the configuration of the silicon gun with reference to FIG. 1.

1 is a perspective view illustrating a conventional silicon gun, in which a stop plate 22 is formed through which a discharge hole (not shown) installed in a silicon tube passes through a silicon tube filled with silicon, and a plurality of silicon guns are disposed at a rear side thereof. Two partitions (hereinafter, referred to as first and second partition walls) 24 and 26 are spaced apart from each other, and a body 20 having a handle 30 protruding from the bottom thereof and a push-up plate inserted into the silicon tube to push the silicon ( A piston 40 is installed at the tip and the push rod 44 penetrates the rear first and second partition walls 24 and 26 of the body 20, the first and second partition walls 24 described above. (26) and the operating plate 50 through which the push rod 44 of the piston 40 penetrates forward and backward, the first partition wall 24 and the operating plate 50 described above. The operating spring 60, which is installed around the push rod 44, is advanced between the operating plate 50 and the hinge 30 in front of the handle 30 of the body 20. The return plate 80 through which the push rod 44 penetrates the operating lever 70 and the second partition wall 26 so as to be inclined to the body 20 so that the other end is rotatable around the one end. ) And a return spring 90 provided between the return plate 80 and the second partition 26 at the outer circumference of the push rod 44.

Looking at the structure and operation of the operating lever 70 and the operating plate 50 in the above configuration in more detail, the operating hole 52 through which the push rod 44 of the operating plate 50 is push rod 44 It is formed a little larger, the operation lever 70 is a plurality of protruding wall 74 is formed protruding to the upper portion of the hinge shaft 72, the operating pin 76 is provided between the protruding wall 74 and The actuating pin 76 is configured to push the lower part of the actuating plate 50 from the rear, and when the actuating lever 70 is pulled, the actuating pin 76 is pushed forward and the lower part of the actuating plate 50 is pushed. The lower part of the operation plate 50, which was initially positioned perpendicular to the push rod 44, is advanced by the operation pin 76 so that the operation plate 50 is slightly inclined in the vertical position with respect to the push rod 44. While the end of the operating hole 52 of the operating plate 50 is in close contact with the push rod 44 to advance the push rod 44 along the forward movement of the operating pin 76. When the operation lever 70 is released, the operation plate 50 is to be retracted by the restoration of the operation spring 60.

And, looking at the configuration and operation of the return plate 80 in more detail, the return hole 82 through which the push rod 44 of the return plate 80 is also formed slightly larger than the push rod 44, In the forward process of the push rod 44, the return spring 90 is slightly inclined in accordance with the advance process of the push rod 44, and the return plate 80, which is installed to be slightly inclined, is positioned perpendicular to the push rod 44. Since the return hole 82 and the outer periphery of the push rod 44 are spaced apart, the push rod 44 can be moved forward. When the push rod 44 is completed and the operating lever 70 is released, the return spring 90 is released. ) Is restored and the return plate 80 is inclined again, so that the push rod 44 and the return hole 82 are in close contact with each other, so that the push rod 44 does not retreat. Only retreat. In addition, when the push rod 44 is fully advanced and cannot be moved any further, when the user pushes the return plate 80 forward, the return spring 90 is pressed and the return plate 80 is pushed with the push rod 44. Being vertical allows the push rod 44 to back up.

The silicon gun configured as described above has the silicon tube mounted on the body 20, and when the operating lever 70 is pulled, the operating plate 50 moves forward by the operation of the operating lever 70, thereby advancing the piston 40. After discharging and releasing the actuation lever 70, the actuation plate 50 is retracted by the actuation spring 60, and the piston 40 is fixed by the return plate 80.

However, in the conventional silicon gun as described above, since the operation pin 76 attached to the operation lever 70 is located under the operation plate 50, the distance between the hinge pin 72 and the operation pin 76 is short. Since the moving distance of the operating plate 50 is relatively short, there was a inconvenience that the operating lever 70 must be operated a plurality of times during the silicon operation.

And the discharge port is usually formed of a resin is cut to a different diameter depending on the working position, because the cutting to use a separate blade for cutting, there is a problem that can not be cut if the blade is not provided.

In addition, there is a problem in that it is inconvenient to use because the operator must separately provide the finishing means for spreading the discharged silicon and the extra discharge hole integrally in the silicon, and if the discharge hole is clogged, use a sharp mechanism such as a nail. It is necessary to pierce the discharge port, which is also not provided with a silicon gun integrally there was a problem inconvenient to use.

An object of the present invention for solving the above problems is to enable the operation pin to be located on the upper portion of the operating plate to increase the ease of use by increasing the moving distance of the piston when operating the operating lever.

In addition, it is an object to facilitate the use by integrally installing a variety of accessories required for the silicon gun gun.

A feature of the present invention for achieving the above object is to form a protruding wall to the upper side of the operating lever so that the end is located at the upper end of the operating plate, and pushes the rear of the operating plate to the end of the protruding wall By installing the operation pin to increase the moving distance of the operation plate.

In the above-described configuration, the silicon gun has an actuating plate for advancing the piston and an elastic release means for depressurizing the return plate to prevent retraction during the forward movement of the piston and to return to the original position when the forward movement is completed. At the moment, as the return plate is returned to the moment, the piston is retracted by a small distance to release the pressurization, but the end of the press release elastic means is provided with a tension control unit screwed to the return plate to release the tension control unit forward / backward. To control the size of the pressurized pressure, and to adjust the forward distance of the return plate by screwing the stop ring in front of the return plate of the tension control.

In addition, the upper part of the body constituting the above-mentioned silicon gun is formed a blade insertion hole for inserting the blade is stored, the blade insertion hole formed a plurality of long hole-shaped guide holes in different dimensions by inserting the discharge port in the guide hole obliquely Position it so that it can be cut with a blade.

And, another feature is to form a support for supporting the discharge port and the closing means in the body, and one side coupled to the body with a fixing pin to be rotatable to the body, the other side is fixed to the body for the discharge hole is blocked In the case of drilling the discharge port by forming a means to be fixed or released, the silicon removal pin is used to be positioned almost perpendicular to the body with respect to the fixing pin.

Silicon gun having the characteristics as described above, the operation pin is installed to operate the operation plate on the upper part of the operation plate so that the position of the operation pin is far from the hinge shaft, which is the connection position of the operation lever and the body, so that the moving distance of the piston is increased. Therefore, it is possible to drastically reduce the operation of the operation lever 20 times for the completion of the advance of the piston about 10 times, thereby improving the convenience of use.

Then, the use of the pressure release elastic means as described above does not flow out of the silicon after the use of the silicone gun, there is no need for the work to remove the flowed out silicon has the effect of convenience.

In addition, as described above, a stop ring is installed to prevent the return plate from being moved too far by the pressure release elastic means as the piston travels longer, which means that the forward distance of the return plate stops when the stop ring is not installed. As the length of the ring becomes longer, the return distance of the piston increases during the return process, which increases the number of times the operating lever for moving forward actually increases.However, when the stop ring is installed, the forward distance of the return plate is limited by the size of the stop ring and the pressurization pressure is reduced. Since the piston is retracted by a very small distance (as far as the advance distance) during the return of the piston, it is possible to achieve the effect of reducing the number of operations by increasing the forward stroke, which is the purpose of the present application. .

On the other hand, the stop ring can be moved back and forth by screwing, so that the user can adjust the retracted length if necessary.

Moreover, since various accessories necessary for the use of the silicon gun are integrally installed on the silicon body, the storage and use of the accessories are made easy.

In addition, the guide hole for cutting the ejection opening of the silicon gun is formed differently, so it is easy to use because it is inserted into the guide hole suitable for the corresponding dimension when cutting the other dimensions, the blade is to be drilled in the long hole to oblique the ejection opening Even if it is cut vertically, since the outlet is cut obliquely, there is a convenient effect.

In the silicon gun of the present invention configured as described above, when the operating lever 70 is pulled after mounting the silicone tube to the body 20, the operating plate 50 is operated by the operation of the operating lever 70 in FIG. 8A. Advancing the piston 40 while advancing to the state to discharge the silicon, in this process the actuating pin 76 of the actuating lever 70 is located above the actuating plate 50, the actuating pin 76 is a conventional actuating plate Since the distance is farther from the hinge axis than the case located at the lower portion of the to increase the discharge amount of silicon. In addition, as the pressure release elastic means 100 is extended during the operation of the operating lever 70, the return plate 80 is also advanced.

If there is no stop ring 109 in this process, since the retraction distance of the piston 40 becomes longer, the actual lever of the piston 40 becomes a limit value as much as the retraction distance, so the operating lever for the forward movement of the piston 40 is performed. (70) The number of operations is increased as compared with the case where the stop ring 109 is used.

Then, when the actuating lever 70 is released, the extended pressure release elastic means 100 is compressed and the return plate 80 is temporarily retracted. In this process, the piston 40 retreats somewhat, so that the pressure inside the silicon tube is reduced. Since the restoring force of the actuation spring 60 is released afterwards, the piston 40 is fixed and the actuation plate 50 is retracted to restore the original position.

Therefore, unnecessary silicon outflow does not occur during the use of the silicon gun, so that the worker does not need to wipe it off with gloves or tissues in order to remove the leaked silicon as in the related art.

In addition, if the tension adjustment device 102 is rotated as necessary to move the position back and forth, the tension of the pressure release elastic means 100 is adjusted to control the size of the pressure to release as needed, stop Rotating the ring 109 to move the position forward / backward allows adjusting the length of the forward / backward of the return plate 80.

As the present invention configured as described above is shown in Figure 9, the advance distance of the piston 40 is long by A to B, the total number of times of operation is greatly reduced.
