Description

[0001] FIELD OF TECHNOLOGY

[0002] The utility model relates to pipeline fittings, namely to devices for regulating the flow rate of gases or liquids flowing through pipes with elastic walls, and can be used in medical equipment, chemical engineering, pneumatic systems, irrigation systems, aeration and in aquarium keeping.

[0003] STATE OF THE ART

[0004] Various types of devices for regulating flow in flexible hoses are known in the art. In particular, valves installed in a hose cut onto fittings are widely used. The disadvantage of such devices is the need to cut the hose, which compromises its integrity and creates a risk of leaks at the connection, especially when using aggressive media. Furthermore, installation and removal of such valves is difficult and requires special tools.

[0005] Also known are adjustable clamps (such as roller or slot clamps), which do not require cutting the hose and operate by localized compression. For example, a roller clamp for infusion systems is known, where the degree of compression of the tubing is adjusted by the position of the roller. A disadvantage of such devices is the difficulty in accurately fixing the position of the adjusting element, as well as the possibility of spontaneous loosening or displacement.

[0006] A prior art invention describes a hose tap (patent RU 2655893C2) comprising a housing with an elastic hose located inside and pressure elements in the form of two rollers. The rollers are mounted on eccentric shafts and are located on opposite sides of the hose.

[0007] The rotation mechanism is a system of gears and shafts, driven by a rotary handle. When the handle is turned, the rollers move in an arc, clamping the pipe. The clamping position can be changed by turning the handle.

[0008] The disadvantages of this device are the complexity and bulkiness of the design, due to the presence of gears, shafts and eccentrics, as well as the impossibility of installing it on an existing pipeline system without dismantling it, since the branch pipe must be placed inside the housing.

[0009] A prior art soft-walled tube clamp (RU Patent No. 237776111) is known, comprising a housing and a channel for passing the soft-walled tube. Two snap-lock latches are provided on the end faces of the housing, along the side. The outer contour of the housing extends along one side of the plane to a height such that, after the latches are closed, the upper plane is parallel to the lower plane. The inner contour of the housing is oval, smoothly transitioning into a triangular surface designed to clamp the soft-walled tube. Triangular surfaces within the housing are conjugated with the inner contour. Openings for accommodating the tube are provided in the center of the end faces of the housing, and the latches are designed to open to form a slit for passing the tube through the opening.

[0010] The disadvantages of the known clamp are the lack of the ability to precisely regulate the flow, the low reliability of the snap locks, which are subject to destruction due to cyclic loads leading to fatigue of the latch material, as well as the impossibility of one-handed operation, which requires simultaneously holding the body and fixing the locks.

[0011] Of the known technical solutions, the closest in purpose and technical essence to the claimed object is a hose clamp for an aquarium and liquid food products (model Schlauchklemme, published on the Printables online platform, 2023 / source https: / / www.printables.com / model / 1366071-schlauchklemme-fur-aquarium-flussignahrung-etc-sch). The known clamp comprises a housing formed from three parts, one of which has a bed for placing a hose, a threaded stop and a threaded and knurled cap screwed onto the stop. When the cap is screwed onto the stop, the hose located in the bed is compressed and the flow is blocked.

[0012] The disadvantages of the known clamp are the difficulty of installation, due to the need to disassemble the device into three parts, the impossibility of using one hand due to the lack of knurling on the lower part of the housing, leading to slippage, as well as increased wear of the hose due to its local compression by flat structural elements.

[0013] DISCLOSURE OF THE ESSENCE OF THE UTILITY MODEL

[0014] The objective of the utility model is to create a simple, reliable and sealed device for regulating the flow in an elastic hose, ensuring easy installation without damaging the integrity of the hose, the ability to precisely adjust with one hand and increasing the service life of the hose due to the gentle effect on it.

[0015] The technical result is to simplify the design.

[0016] This technical result is achieved by a hose clip comprising a bottom cover (cradle) and an upper cover with a fixed stem, each formed as a single piece. The bottom cover is ribbed on the outside. A cylinder is coaxially positioned within the bottom cover, with a threaded outer surface. The cylinder has a through-hole forming a hose cradle. A longitudinal slit (gap) is made in the cylinder wall, extending from the top of the cylinder to the opening. This slit provides lateral access to the opening, allowing the hose to be placed in the cradle by inserting it transversely through the slit, without the need to thread the hose through the end or cut it. The slit is narrower than the opening diameter, requiring gentle finger pressure on the hose during installation and ensuring its retention in the cradle after installation.

[0017] The top cap is ribbed on the outside. The interior of the top cap is threaded to match the threads on the bottom cap cylinder. A rod with a spherical free end is coaxially attached to the top cap. When the top cap is screwed onto the bottom cap cylinder until it stops, the outer edges of both caps align flush, forming a single surface, ensuring a compact device and preventing accidental snagging. The spherical shape of the rod end ensures even pressure distribution on the hose wall, preventing localized damage and reducing wear. Ribbed surfaces on both caps allow for a secure grip and one-handed operation, even when wet.

[0022] IMPLEMENTATION OF A UTILITY MODEL

[0023] Further, all components of the proposed utility model are described in detail with reference to the drawings and the reference numbers indicated therein for a more complete understanding of the scope and all technical aspects of the claimed technical solution by a person skilled in the art.

[0024] The hose clip tap consists of a lower cover (1) (Fig. 1) and an upper cover (2) (Fig. 2), made integral with the rod 3. Both main parts are manufactured as single-piece parts by casting or 3D printing from a hard material, such as plastic, metal, composite, etc.

[0025] The bottom cover (1) is provided with a knurling (4) on the outside. Inside the bottom cover (1), a cylinder (5) is located coaxially with it, at the base of which a through longitudinal hole (6) is made, passing through the bottom cover (1) and forming a bed for placing a hose. In the wall of the cylinder (5), a longitudinal cut (slot) (7) is made, extending from the top of the cylinder to the hole (6). The longitudinal cut (7) provides access to the hole (6) from the side, which allows you to fix the tap clip on the hose already installed in the system by inserting it transversely. The width of the slot (7) is less than the diameter of the hole 6, therefore, during installation, light compression of the hose with your fingers is required, and after installation, the walls of the slot prevent the hose from spontaneously falling out. A thread (8) is made on the outer surface of the cylinder (5).

[0026] The top cover (2) is provided with knurling (9) on the outside. The inner cavity of the top cover (2) has an internal thread (10), mating with the thread (8). A rod (3) is coaxially attached to the top cover (2), the free end (11) of which has a spherical shape. The knurling (4) and (9) can be made, for example, in the form of vertical or horizontal grooves, as well as at any angle to the longitudinal axis of the part, providing a rough surface for more secure fixation in the user's hand. The bottom cover (1) and the top cover (2) can be made round, square, oval, triangular, or any other shape convenient for gripping and rotating. The given examples of shapes do not limit the scope of legal protection, but only illustrate possible design options.

[0027] The installation and use of the device is as follows.

[0028] The lower cover (1) and the upper cover (2) are separated. The user selects the desired location on (Fig. 3) the hose (12) and lightly squeezes it with his fingers, thereby reducing its cross-section. Then, through the gap (7), the user places the hose into the longitudinal opening (6) of the lower cover until it stops. After releasing the compression, the hose straightens out and is securely fixed in the opening. Next, the upper cover (2) is oriented with the rod (3) towards the cylinder of the lower cover, and the rod is inserted inside the cylinder. By rotating the upper cover, its internal thread (10) engages with the thread 8 on the cylinder. With further screwing, the upper cover is lowered, and the rod (3) moves progressively toward the hose. The free end (11) of the rod acts on the hose (12), deforming it and pinching the clearance. When fully screwed on, the outer edges of both covers are flush.

[0029] The device is operated with one hand: the bottom cap (1) is gripped in the palm of the hand with the little, ring, and middle fingers, and the top cap (2) is rotated with the thumb and index finger using the knurled grip (9). The knurled grip ensures a secure grip, even when hands are wet. The degree of hose compression is smoothly adjusted by rotating the top cap. When fully tightened, the flow is completely shut off. The spherical shape of the rod end distributes pressure evenly across the hose wall, preventing localized damage and extending the hose's lifespan.

[0030] The proposed technical solution does not require tools for installation, ensures a tight seal by maintaining the integrity of the hose, allows for one-handed operation of the device, is securely fixed, provides smooth flow adjustment and is gentle on the hose.
