Description

Technical field

The invention relates to devices for applying liquid substances to various surfaces, in particular, to a construction gun for applying liquid substances to the surface, for example, foam and sprayable compositions.

State of the art

In modern construction, sealing substances are widely used, one of which is polyurethane foam. In addition to sealing properties, polyurethane foam has heat and sound insulating properties, and can also serve as a means of fixation and fastening. To apply the mounting foam, special construction guns are used, to which cylinders containing a liquid mixture are attached, forming a mounting foam when applied.

The gun for applying polyurethane foam typically includes a body, a barrel, at the end of which there is a tip for the exit of polyurethane foam and a rod located inside the barrel and forming a needle valve that controls the flow of foam. The composition of the gun also includes a handle, a lever for controlling the flow of foam and a cylinder attachment device. In the center of the tip there is a round hole for the exit of the mounting foam. A similar device is described, for example, in the source / 1 / RU 2488451 published on July 27, 2013 and in the source / 2 / “[Expert Advice] Choosing a gun for foam” // URL: https://kudo-purfoam.ru/blog / vibor-pistoleta-dlia-montaznoi-peni / (accessed March 18, 2020). The device described in the source / 1 /, selected by the applicant as the closest analogue (prototype) of the utility model.

In addition to polyurethane foam, various aerosols having a more liquid consistency are used in construction. Such materials include, for example, sprayed heaters used to warm buildings as an alternative to coil and plate heat insulators. Materials such as polyurethane foam are traditionally supplied in cylinders and can be applied to the work surface using the construction foam gun described above.

However, for uniform application of such material, it is necessary to obtain a wide spray pattern. Since the round outlet of the tip of a traditional gun does not allow to obtain the required spray pattern, special nozzles with an outlet of the desired shape are put on the tip to spray the insulation. Using these nozzles, you can obtain the desired spray pattern or change the direction of spraying.

Such nozzles are known, for example, from source / 3 / RU 193962 published on 11/21/2019, source / 4 / RU 2623276 published on 06/23/2017, and source / 5 / “Polynor insulation” // URL: http: // polymer- tyumen.ru/products/penopoliuretan_ppu/uteplitel-polynor-polinor-tyumen/ (accessed March 18, 2020).

Nozzles are independent devices and are most often sold separately from guns, while considering that the tips of different guns may have a different shape, the nozzle that fits one gun may not fit another gun. Thus, for spraying polyurethane foam and sprayed insulation using one construction gun, it is necessary to purchase nozzles suitable for this particular gun. In addition, since the nozzle is a separate and rather miniature device, it may be lost, especially in the specific operating conditions of construction guns. Finally, significant efforts are required to make the nozzle firmly attached to the gun tip. All of the above reduces the usability of tools for applying liquids and increases the execution time of the relevant work.

Based on the foregoing, the technical problem to which the utility model is directed is to create a universal construction gun suitable for both mounting foam and spraying compositions without the use of additional nozzles.

Utility Model Disclosure

The aforementioned technical problem is solved in this utility model by creating a construction gun for spraying liquid substances, comprising a body, a handle, a barrel, at the end of which there is a tip for the exit of liquid substance, and a device for attaching a cylinder with liquid substance, and a rod for controlling flow is placed in the barrel liquid substance connected to a control lever configured to move the rod, characterized in that the tip is made V-shaped, expanding in the direction of exit of the liquid substance.

As can be seen from the above, the construction gun design according to the utility model is generally similar to the construction of a traditional construction gun for polyurethane foam, which allows it to be used for applying polyurethane foam. At the same time, the execution of a V-shaped cut-out at the tip, expanding in the direction of liquid exit, allows the use of a construction gun also for spraying substances having a more liquid consistency and requiring application to a surface with a wider spray pattern without the use of additional nozzles.

In accordance with an embodiment of the utility model, the tip is made in the form of a fitting in which said V-neck is made.

This embodiment of the tip allows, if necessary, to put additional devices on the tip.

In accordance with an embodiment of the utility model, the tip is made integrally with the barrel.

In such an embodiment, the manufacturing process of the construction gun is simplified.

In accordance with another embodiment of the utility model, the tip is configured to detachably connect to the barrel.

This manufacture of the tip allows you to simplify the cleaning of the construction gun in case of contamination with residues of liquid substances.

In accordance with an embodiment of the utility model, the barrel is collapsible, which also helps facilitate gun cleaning.

In accordance with an embodiment, the attachment device of the container with the liquid substance is a universal adapter configured to attach to the adapter for cylinders of the "cross-shaped ring". This allows the device to be used with cylinders widely available on the market and equipped with cross-shaped adapters.

Brief Description of the Drawings

The following describes in detail an example implementation of a utility model with links to the attached drawings, in which:

in FIG. 1 schematically shows a construction gun according to a utility model in its entirety;

in FIG. 2 is a perspective view showing the tip of a construction gun according to a utility model;

in FIG. 3 shows a side view of the tip of a construction gun according to a utility model.

Utility Model Implementation

In FIG. 1 schematically shows a construction gun according to a utility model, indicated generally by the position number 1. The construction gun comprises a housing 2 connected to a barrel 3, at the end of which there is a tip 4, which is a nozzle for the exit of the substance to be applied to the surface to be treated. The barrel 3 can be made in the form of a single element or consist of two elements and be collapsible, which facilitates the process of cleaning it from the remnants of liquid substances.

The main elements of the construction gun 1 also include a handle 5, a control lever 6, for controlling the supply of liquid substance and a device 7 for securing the container containing the liquid substance to be applied.

In the described embodiment, the device 7 for mounting the container with a liquid substance is a universal adapter configured to attach to the well-known adapters of the type "cross-shaped ring" placed on the cylinders.

Inside the barrel 3 there is a rod 8 (partially shown in FIGS. 2 and 3), designed to control the flow of liquid substance leaving the cylinder and connected to the control lever 6. In the initial position, the rod 8 closes the outlet of the tip 4. Pressing the lever 6 for supplying liquid substance causes the rod 8 to move inside the barrel 3 so that the rod moves away from the outlet, opening a passage for the liquid substance.

Optionally, the construction gun 1 may also comprise an adjustment screw (not shown in the drawings). When changing the position of the screw, an increase or decrease in the stroke of the control lever 6 occurs. If the adjusting screw is fully tightened, then the control lever 6 is in a fully locked position. The adjusting screw is designed to control the volume of fluid supply, i.e. the thickness of the jet of foam emerging from the tip.

In terms of the features described above, the construction gun 1 is similar in design to a conventional construction foam gun. The materials used in the manufacture of such a gun, as well as the principle of its operation, are widely known and are not considered in detail in this application.

The tip 4, located at the end of the barrel, as a whole is a traditional tip used in the known construction guns for mounting foam. Such a tip may be made, for example, of brass and other suitable material.

According to a utility model, a V-shaped cutout 9 is made in the tip 4, expanding in the direction of exit of the liquid substance.

Such a V-shaped cutout 9 in the tip can be made in any suitable way, for example, using turning equipment.

The specified shape of the tip allows you to get a wide spray pattern, which is necessary when applying to the treated surface such substances as, for example, polyurethane sprayable insulation, or any other substances that require a wide torch and suitable for application using a construction gun of the above construction.

At the same time, a construction gun containing such a tip remains suitable for applying mounting foam. Due to the denser consistency of the mounting foam, as well as adjusting the speed or quantity of its supply by pressing the lever, it will not spatter when exiting the tip having a V-shaped cut, that is, the shape of the tip will not significantly affect the shape emerging from the tip of the foam mounting foam.

Thus, the proposed device is a versatile construction gun, suitable for both mounting foam and sprayable compositions without the need for additional nozzles.

At the same time, the design of the gun, which is itself suitable for spraying liquids of various consistencies, does not exclude the possibility of using additional parts, for example, if necessary, change the direction of spraying or use a flexible hose to “extend” the gun barrel or spray the substance in a hard-to-reach place .

For this, according to an embodiment of the utility model, the tip can be made in the form of a fitting to which the above-mentioned parts can be connected.

The tip 4 can be made in one piece with the gun, or connected to it in a detachable or one-piece way. The detachable connection may be, for example, a threaded connection or any other suitable connection.

It should be noted that according to the utility model, the tip 4 is an integral part of the construction gun and if it is removable, it is detached only if the gun is disassembled and / or cleaned.

As in the case of spraying mounting foam, and in the case of a sprayable composition, work with the construction gun 1 according to the utility model is carried out identically. To get started, a container containing a liquid substance to be applied to the surface to be treated — components of the mounting foam or sprayed composition — is attached to the device 7 for securing the balloon.

After that, holding the handle 5 of the gun in hand, apply the substance contained in the container to the surface to be treated, controlling the flow of the substance using the control lever 6.
