Description

A cartridge of minimizing discharge of residual contents and a caulking gun using the same}

The present invention relates to a cartridge, and more specifically, by allowing certain free movement of the cartridge stopper inside the cartridge body, when the rod rod is retracted, the pressure inside the cartridge body is lowered as the cartridge stopper retracts, thereby allowing particles such as cement to be removed. It relates to a cartridge that can minimize the residual flow of large contents into the nozzle part and a caulking gun using the same.

In general, silicon is used for various finishing works at construction sites or at home, especially for filling gaps between glass and window frames, finishing interior and exterior walls of buildings, or finishing work on bathrooms and sinks at home. It is widely used.

Caulking refers to the process of shooting the contents loaded into a cartridge to close any cracks or gaps.

For example, if the contents of the cartridge are silicon, it can be called a silicone gun. When the silicone filled in the silicone cartridge is mounted in the charging chamber of the silicone gun and the trigger lever is pulled with the user's grip, a clamper formed integrally with the trigger lever is formed. As the bolt clamped by the clamping hole moves forward, the pressure plate at the tip of the bolt presses the piston of the silicon cartridge, discharging the silicon filled in the silicon cartridge forward, and caulking can be performed.

Korean patent publication KR 10-2012-0002904 is an invention regarding a silicone gun that prevents vibration, noise, and leakage. A spring formed at the bottom of the return plate automatically retracts the load bar to prevent silicone leakage.

Figure 1 is a configuration diagram of a cartridge that minimizes discharge of residual contents according to a preferred embodiment of the present invention.

Referring to FIG. 1, the cartridge that minimizes discharge of remaining contents according to this embodiment is composed of a nozzle portion 100, a nozzle coupling portion 110, a cartridge body portion 120, and a cartridge cap portion 130.

The nozzle unit 100 is an outlet through which the contents of the cartridge body 120 are discharged by external pressure. The interior of the nozzle unit 100 coupled to the nozzle coupling unit 110 may be formed with a female thread.

The nozzle coupling portion 110 is preferably in the shape of a screw thread in order to be coupled to the nozzle portion 100. The nozzle coupling part 110 may have male threads formed on the upper surface of the cartridge body 120.

The cartridge body 120 has a cylindrical shape and contains contents discharged through the nozzle 100. It is preferable that the nozzle coupling portion 110 is formed on the upper surface of the cartridge body 120, and the cartridge cap portion 130 is coupled to the lower portion. The contents may be caulking materials such as silicone, epoxy, cement, and urethane.

The compression plate 220 of the caulking gun advances the cartridge stopper 130 into the cartridge body 120 to discharge the contents of the cartridge body 120 through the nozzle unit 100.

When the cartridge stopper 130 stops moving forward, residue may be discharged through the nozzle unit 100 or through the empty space between the cartridge stopper 130 and the cartridge body 120. You can. When the caulking operation is temporarily interrupted and the cartridge cap 130 is stopped, some of the contents are pushed out through the nozzle 100 because the internal pressure of the cartridge body 120 remains, resulting in unnecessary waste of contents. do.

In the case of a conventional cartridge without an empty space between the cartridge stopper 130 and the cartridge body 120, the remaining contents are hardly discharged between the cartridge stopper 130 and the cartridge body 120, but the cartridge stopper ( 130), a large amount of remaining contents are discharged.

Table 1 is a table measuring the nozzle residual silicon flow amount and the cap residual silicon flow amount according to the outer diameter of the cartridge cap 120 when the inner diameter of the cartridge body 120 is 46.1 mm.

Stopper outer diameter 45.4mm 45.5mm 45.6mm 45.7mm 45.8mm 45.9mm 46mm 46.1mm Nozzle remaining flow amount 0.1g 0.1g 0.2g 0.2g 0.2g 3.5g 3.8g 4.2g Stopper residual flow 0.8g 0.5g 0.2g 0.2g 0g 0g 0g 0g

When the inner diameter of the cartridge body 120 is 46.1 mm, that is, when the inner diameter of the cartridge body 120 and the outer diameter of the cartridge stopper 120 are the same, the stopper remaining flow amount is 0g, while the nozzle remaining flow amount is 4.2. g, a lot of content flows out through the nozzle unit 100.

Conversely, when the inner diameter of the cartridge body 120 is 45.4 mm, that is, when the outer diameter of the cartridge stopper 120 is relatively smaller than the inner diameter of the cartridge body 120, the remaining flow amount from the nozzle is 0.1 g, but almost no flow occurs. , the remaining flow amount of the stopper is 0.8g, which shows that a relatively large amount flows out.

Figure 2 is a graph showing the nozzle remaining flow amount and the stopper remaining flow amount according to the outer diameter of the cartridge cap 130 when the inner diameter of the cartridge body 120 is 46.1 mm.

Referring to FIG. 2, it can be seen that when the inner diameter of the cartridge body 120 increases from 45.8 mm to 45.9 mm, the remaining flow amount of the stopper does not change, but the remaining flow amount of the nozzle rapidly increases from 0.2 g to 3.5 g.

In addition, when the inner diameter of the cartridge body 120 is reduced from 45.6 mm to 45.5 mm, there is almost no change in the nozzle residual flow amount, but it can be seen that the cap residual flow amount increases significantly from 0.2 g to 0.5 g.

Therefore, when the cartridge stopper 130 stops moving forward, the cartridge stopper 130 has the outer diameter of the cartridge stopper 130 relative to the inner diameter of the cartridge body 120 to prevent the contents of the cartridge from flowing outward. It is desirable for the ratio to be 98.9% to 99.3%.

The cartridge stopper 130 may be configured to be replaced in order to vary the size of the outer diameter of the cartridge stopper 130.

Figure 3 shows a photograph of the flow of nozzle residue and a flow of plug residue according to the outer diameter of the cartridge cap 120 when the inner diameter of the cartridge body 120 is 46.1 mm.

Referring to FIG. 3, when the outer diameter of the cartridge stopper 120 is 45.5mm, it can be seen that the flow amount of the nozzle part is almost 0.1g, but the flow amount of the stopper is discharged as much as 0.5g.

In addition, when the outer diameter of the cartridge stopper 120 is 46.1 mm, the flow amount of the stopper part is 0g and the flow amount of the nozzle part is 4.2g, so a lot of remaining contents are flowing out through the nozzle part 100.

According to one embodiment of the present invention, when the outer diameter of the cartridge stopper 120 is 45.7mm, it can be seen that the flow amount of the nozzle part is 0.2g and the flow amount of the stopper part is 0.2g, so that a small amount of contents flows out overall.

Figure 4 is an enlarged view of the joined portion of the cartridge body 120 and the cartridge stopper 120.

It is desirable for the cartridge stopper 130 to have a ratio of the outer diameter of the cartridge stopper 130 to the inner diameter of the cartridge body 120 of 98.9% to 99.3% in order to prevent the contents of the cartridge from flowing outward. There is a distance d between one end of 130 and the cartridge body 120.

If the thickness w of the cartridge stopper 130 is less than twice the distance d between one end of the cartridge stopper 130 and the cartridge body 120, the cartridge stopper 130 is inside the cartridge body 120. Since it can rotate, the thickness w of the cartridge stopper 130 is preferably greater than twice the distance d.

The reason why the thickness w must be greater than twice the distance d is because the distance d between one end of the cartridge stopper 130 and the cartridge body 120 and the distance d between the other end of the cartridge stopper 130 and the cartridge body 120 This is because both the distance d, that is, the distance between the top and bottom of the cartridge stopper 130 and the cartridge body 120, must be considered.

At the same time, the cartridge stopper 130 can move within the cartridge body 120 in the axial direction without much friction, and at the same time, the cartridge body 120 and the It is desirable to secure enough space between the cartridge cap portion 120 to prevent the contents from coming out.

Figure 5 is a configuration diagram of a cartridge that minimizes discharge of residual contents according to another preferred embodiment of the present invention.

The cartridge with minimal discharge of remaining contents according to the present embodiment shown in FIG. 5 is different from the cartridge shown in FIG. 1 in the configuration of the cartridge body 121 and the cartridge cap 140.

The cartridge body 121 is connected to the nozzle coupling portion 110 and the inclined surface 31. Since the discharge diameter of the nozzle coupling part 110 is smaller than the diameter of the cartridge body 121, it is preferable to be connected to the inclined surface 31.

The cartridge stopper 140 shown in FIG. 5, unlike the cartridge stopper 130 shown in FIG. 1, includes a base part 41, an inclined surface part 42, and an upper surface 43.

The base portion 41 receives pressure through the compression plate 220 of the caulking gun and transmits the received pressure to the inside of the cartridge body 121. The surface where the base 41 contacts the compression plate 220 is preferably flat so that they are in close contact with each other.

When the cartridge stopper 140 shown in FIG. 5 stops moving forward, like the cartridge stopper 130 shown in FIG. 1, the cartridge stopper 140 closes the cartridge body to prevent the contents of the cartridge from flowing outward. It is preferable that the ratio of the outer diameter of the base portion 41 to the inner diameter of the portion 121 is 98.9% to 99.3%.

The inclined surface portion 42 connects the base portion 41 and the upper surface 43. The upper surface 43 has a smaller diameter than the diameter of the base portion 41 and is connected through the inclined surface portion 42.

It is preferable that the inclined surface 42 of the cartridge stopper 140 has the same inclination as the inclined surface 31 of the cartridge body 121.

The upper surface 43 has a circular cross-section, and preferably has a diameter corresponding to the diameter of the nozzle coupling portion 110.

The cartridge that minimizes discharge of remaining contents according to the present embodiment shown in FIG. 5 has the slope of the inclined surface 42 of the cartridge cap 140 being the same as the inclined surface 31 of the cartridge body 121, The contents of the cartridge body portion 121 can be easily discharged through the nozzle portion 100.

Figure 6 is a configuration diagram of a cartridge that minimizes discharge of residual contents according to another preferred embodiment of the present invention.

The cartridge with minimal discharge of remaining contents according to this embodiment shown in FIG. 6 is different from the cartridge shown in FIG. 5 in the configuration of the cartridge body portion 120 and the cartridge cap receiving portion 51.

The cartridge body 121 in FIG. 5 is connected to the nozzle coupling portion 110 and the inclined surface 31, but the cartridge body 120 in FIG. 6 is without the nozzle coupling portion 110 and the inclined surface 31. It is connected.

The cartridge stopper 140 in FIG. 6 has the same shape as the cartridge stopper 140 in FIG. 5 .

The cartridge stopper 140 of FIG. 6 is pushed from one end to the other end of the cartridge body 120 under pressure through the compression plate 220 of the caulking gun, and the upper surface 43 is connected to the nozzle coupling portion 110 or the cartridge. The other end of the body portion 120 can be reached.

At this time, it is preferable that a stopper receiving portion 51 is further included in the cartridge body 120 of FIG. 6 so that the cross section of the upper surface 43 can be brought into close contact with the other end of the cartridge body 120.

The stopper receiving portion 51 is disposed and fixed at the other end of the cartridge body 120, receives the cartridge stopper 140, and guides it to the nozzle coupling portion 110.

The stopper accommodating portion 51a is a perspective view viewed from direction a, and the stopper accommodating portion 51b is a perspective view viewed from direction b.

The stopper receiving portion 51 includes a bottom surface 52, a receiving surface 53, and a discharge port 54.

The bottom surface 52 can support the pressure from the cartridge cap 140 by being in close contact with the surface of the other end of the cartridge body 120.

It is preferable that the discharge port 54 is formed in the center of the bottom surface 52. The discharge port 54 serves as a gateway through which the contents of the cartridge body 120 are pushed out to the nozzle coupling portion 110 by the pressure of the cartridge cap portion 140. The diameter of the discharge port 54 is preferably a size corresponding to the discharge diameter of the nozzle coupling portion 110.

The receiving surface 53 is a surface in close contact with the inclined surface portion 42 of the cartridge stopper 140. It is desirable that the slope of the receiving surface 53 be the same as that of the slope part 42 of the cartridge stopper 140.

Figure 7 shows the configuration of a caulking gun to which a cartridge that minimizes discharge of remaining contents is combined according to a preferred embodiment of the present invention.

The caulking gun of FIG. 7 includes a compression plate 220, a rod rod 230, a guide body 240, a trigger 250, and a flow prevention portion 260.

The compression plate 220 applies pressure to the cartridge cap 130 at the rear of the cartridge body 120 so that the contents of the cartridge body 120 come out from the nozzle 100.

Instead of the compression plate 220 connected to the rod rod 230 of the caulking gun according to an embodiment of the present invention, the cartridge stopper 130 may be connected to the rod rod 230.

In this case, it is preferable that the cartridge stopper 130 has a female thread and one end of the rod rod 230 has a male thread. When replacing the compression plate 220 with the cartridge stopper 130, the configuration of the caulking gun can be simplified and costs can be reduced.

The rod rod 230 has a compression plate 220 connected to one end, and a latch that allows the rod rod 230 to move a certain distance each time the trigger 250 is pulled is connected to the other end.

The guide body 240 guides the compression plate 220, which applies pressure to the rear of the cartridge body 120, in a certain direction.

Each time the trigger 250 is pulled, the rod rod 230 advances and the compression plate 220 advances a certain distance, thereby causing the contents of the cartridge body 120 to come out through the nozzle 100.

When the cartridge according to an embodiment of the present invention is mounted on the guide body 240 and the trigger 250 is pulled, the rod rod 230 moves forward and pushes the inside of the cartridge body 120, the cartridge Contents stored in the body portion 120 are discharged through the nozzle portion 100.

That is, the rod rod 230 is moved forward by the operation of the trigger 250, and in the state before the trigger 250 is pulled, the flow prevention portion 260 is attached to the spring 261 on one side of the guide groove 262. ) is provided to be elastically supported, and when the trigger 250 is pulled, it moves forward together with the rod rod 230 and is caught in the guide groove 262, so that only the rod rod 230 moves forward. At this time, when the spring 261 is caught in the guide groove 262, the spring 261 is in a tense state. In this process, the flow prevention portion 260 comes into close contact with the buffer member 263 and absorbs noise and shock.

Then, when the trigger 250 is released, the spring 261 forces the flow prevention unit 260 to move backwards, and thus the rod rod 230 coupled to the flow prevention unit 260 moves backwards. At this time, the flow prevention unit 260 moves backward and returns to its initial state.

In this way, by pulling the trigger 250, after the forward motion of the rod rod 230, the flow prevention portion 260 is moved backward by the distance of the guide groove 262 by the spring 261, and the rod rod 230 By forcibly moving backwards, the contents stored within the cartridge body 120 can be prevented from being discharged forward.

It is preferable that the elastic force of the spring 261 is applied to one side of the flow prevention unit 260, so that the flow prevention unit 260 is tilted backward. In this case, the inclination of the flow prevention unit 260 is adjusted to the fixed handle ( It is preferable that it is formed to correspond to the slope of 251).

According to one embodiment of the present invention, the outer diameter of the cartridge stopper 130 is made smaller than the cartridge body 120, and the trigger 250 is activated by the pressure inside the cartridge body 120 generated when the trigger 250 is pulled. After pulling, the cartridge stopper 130 retreats so that the internal pressure continues to act in the direction of the nozzle unit 100, thereby preventing the flow.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those skilled in the art can make various modifications and variations from this description.
