Description

Easy replaceable one-touch hose connector {Coupling type Hose Connector}

The present invention relates to a connector that leads to the interconnection of a main hose through which water is supplied and an auxiliary hose for extending the length of the main hose. More specifically, it relates to a connector in the middle of the connector that interconnects the main hose and the auxiliary hose. By constructing the parts in a form that can be separated and reassembled, not only is it extremely easy to attach and detach the auxiliary hose from the main hose, but it is also able to fundamentally solve the water leakage problem caused by hose diameter expansion caused by repeating the hose connection and removal process several times. This relates to a simple replaceable one-touch hose connector that maximizes convenience of use and efficiency due to ease of handling, use, maintenance, and repair resulting from a structure differentiated from the existing one.

Typically, a hose must be provided to supply various types of water stored in a faucet or tank to a designated location, and sometimes, in order to supply water to an unexpected range, the problem is overcome by connecting an auxiliary hose to the main hose.

For example, a method of connecting the main hose and the auxiliary hose is to insert an auxiliary hose with a smaller diameter than the inner diameter of the main hose into the inner diameter of the main hose and then secure the overlapping area by wrapping it with waterproof tape. However, in this method, it is difficult to provide hoses of diameters that can be inserted into each other, and soon water leaks occur at the connection area.

This is not only a problem for connecting a pair of hoses, but the same problem applies to connecting a water nozzle and a hose, and a 'connector' is provided for the purpose of solving this problem. However, existing connectors have a cumbersome structure not only for connecting with the hose, but also for connecting, so they do not guarantee satisfactory use efficiency.

Meanwhile, in relation to existing connectors, Registered Utility Model Publication No. 20-0155869, “Water Inlet Hose Connector for Electric Washing Machine,” is published, and the technology is used to connect the water inlet hose to the water cock, that is, the wash water inlet hose of the electric washing machine. The purpose is to provide a connector. This connector has a separate filter built in between the binding member and the connection member, and is further equipped with a viewing tube that allows the filter state to be identified from the outside, making it possible to easily identify the state of the connector. Here, the connector strengthens the coupling between the faucet and the binding member by inserting the binding member into the faucet and tightening a plurality of bolts around the binding member.

The above technology is inconvenient in use because it requires manipulating several bolts to connect or separate the connector, which is commonly seen around us. In addition, with frequent use, the bolts are worn out or the area where the bolts are inserted is easily damaged. There was a problem with the lifespan being short, such as becoming impossible.

Other technologies related to existing connectors include Registered Patent Publication No. 10-0623939, “Hose Kink Prevention Connector and Method of Manufacturing the Same,” which is a hose connector with a plurality of steps at one end and a hose fixed at the other end. ;And, an air tool connector having a plurality of steps at one end and an air tool connected to the other end; And, a male connection tube inserted into the inner diameter of the hose connector at one end and having an elastic ring and a sealing ring at the other end; And, air A female connector inserted into the inner diameter of the tool connector and coupled to one end of the male connector; and a plurality of metal balls inserted into the inner diameter of the air tool connector and the hose connector, respectively, to rotate the female connector and the male connector. It is a technology consisting of ; and a cover that is attached to one end of the air tool connector and the hose connector to prevent the metal ball from coming off. This technology makes it convenient to use the hose because the metal ball rotates freely, preventing the hose from becoming twisted.

In the above technology, the nozzle of the air tool is coupled to the air tool connector, separate parts are provided to enable the air hose to be coupled to the hose connector, and when the air tool and air hose are each coupled, each metal ball is bolted to the other. A method of connection is proposed by fastening in the form of a combination of and nut.

However, since the above technology is such that the metal ball rotates freely within the air tool connector and the hose connector, when the air tool connector and the hose connector are later separated from each other, each metal ball is connected to the air tool connector and the hose connector. It cannot be separated because it spins around in the tube.

In other words, in the above technology, if one of the air tool connector and the hose connector is damaged and loses its function, and if the hose connector is replaced because the diameter of the air hose is different, partial replacement is not possible, so the connector from the air tool is not possible. There is an inconvenience in having to separate and replace them all.

As mentioned above, existing connectors do not detach on their own, or even if detached, operation is cumbersome, so they endure the inconvenience of using them as is without detaching as much as possible.

As a result, there is an urgent need for a new concept hose connector that can more quickly and conveniently connect and separate different pairs of hoses, thereby maximizing the speed and convenience of hose replacement.

In addition, the same reference numerals refer to the same elements throughout the specification.

The present invention relates to a connector that leads to the interconnection of a main hose through which water is supplied and an auxiliary hose for extending the length of the main hose.

Above all, the present invention is configured in a form that can separate and reconnect the middle part of the connector connecting the main hose and the auxiliary hose, so that not only is it extremely easy to attach and detach the auxiliary hose from the main hose, but the process of connecting and removing the hose is repeated.

The present invention is a connector (1) for connecting a pair of different hoses. This connector is used in various situations such as connection between hoses, as well as connection between water nozzles and hoses, connection between pipe bodies and hoses, and connection between pipe bodies. It is assumed that it can be used accordingly.

The connector (1) is divided into a main body (100) coupled to one edge of the main hose, and a connection body (200) connected to one edge of the auxiliary hose, and a connection body at the bottom of the main body. It is characterized by a structure and technology that are integrated by directly connecting.

The main body 100 is divided into a frame 110 that allows internal intervention of the main hose, and an operation unit 120 that strongly tightens the overlapping area between the frame and the main hose to induce restraint of the main hose.

The structure of the frame 110 consists of an insertion part 111 from the bottom, a fastening part 112 on the upper side of the insertion, and a fastening part 113 on the upper side of the fastening part, and can be provided in various forms as shown in FIG. 3. .

The insertion part 111 is made of a cylinder of a set diameter and is connected by fitting the upper part of the connection body 200. In particular, packing is interposed in the area overlapping with the connection body to completely prevent water leakage that may occur between the insertion part and the connection body. prevent it from happening.

The fastening portion 112 refers to a portion that protrudes upward from the insertion portion with a diameter slightly enlarged compared to the insertion portion 111. The fastening part 112 has screw threads formed along its outer circumference, and the manipulation part 120 is installed overlapping the fastening part through the screw threads.

The tightening part 113 is made of a cylinder of a set diameter, and the end of the main hose is connected by fitting, and a protrusion 113a in the reverse direction is formed along the outer circumference to prevent the fitted main hose from coming off. The tightening part 113 has a diameter of upper and lower narrowing, so that the coupling force can be increased by the expansion force of the main hose when inserting the main hose, and by forming a plurality of protrusions 113a at equal intervals in the vertical direction, it is connected to the main hose. The bonding force can also be increased by maximizing the friction force.

The manipulation unit 120 is installed overlapping the frame 110 through the upper side of the tightening part 130, and is connected to the thread of the fastening part 112 to rise or fall on the fastening part depending on the degree and direction of tightening.

For example, a preset clearance is secured between the outer diameter of the tightening part 130 and the inner diameter of the operating part 120 to allow insertion of the main hose, and whenever the tightening part 130 descends on the fastening part 112, As the inner diameter of the fastening part approaches the protrusion (113a) of the fastening part, the free space is gradually reduced, and as a result, the side of the main hose inserted into the protrusion is strongly pressed. Accordingly, the main hose is restrained in the fastener 130. When the operation unit 120 is turned in the reverse direction again and raised and lowered from the fastening unit 112, the reduced free space expands as the operation unit moves away from the protrusion 113a, and as a result, the restraining force applied to the main hose is released.

The connecting body 200 is coupled to one end of the auxiliary hose and is connected to the main body 100 coupled to the main hose to receive water discharged from the main hose and supply it to the auxiliary hose.

The connection body 200 includes a housing 210 coupled to an auxiliary hose; and a locking part 220 that induces manual operation by the user so that the housing can be restrained to the main body 100; and a manipulated locking part. It is composed of a spring 230 that automatically returns to its original position.

The housing 210 is made of a cylindrical shape with upper and lower inner cylinders, providing a coupling space so that the insertion part 111 of the main body 100 is vertically inserted, and at the same time, it takes over the water provided by the faucet and supplies it to the hose.

The structure of the housing 210 consists of a coupling portion 211 based on the lower side, a seating portion 212 protruding above the coupling portion, and a restraining portion 213 protruding above the seating portion.

The coupling portion 211 is made of a cylinder of a set diameter and the end of the auxiliary hose is fitted and connected. In particular, an inverted triangular second protrusion 211a is formed along the outer circumference to prevent the fitted auxiliary hose from being separated.

The seating portion 212 extends and protrudes from the top of the coupling portion 211 with a diameter slightly expanded compared to the coupling portion, and serves to seat the locking portion 220 and limit the range of downward movement of the locking portion. .

The restraining part 213 extends and protrudes from the top of the seating part 212 with a diameter somewhat reduced compared to the seating part, and the insertion part 111 of the main body 100 is vertically intervened in the upper and lower inner space, and the outer The spring 230 and the locking part 220 are installed to overlap and play the role of fixing the vertically inserted insertion part according to the operation of the locking part.

This restraint portion 213 includes a plurality of through holes 213-1 formed at set intervals on the outer circumference, and further includes a fixing plate 213-2 interposed on the side of each through hole. As the vertical position of the locking part 220 changes, the fixing member 213-2 enters or leaves the internal space of the restraining part 213 through the through hole 213-1.

For example, the fixture 213-2 enters the inner space of the restraint portion 213 when the locking portion 220 is raised and lowered and fixes the insertion portion 111 of the main body 100 vertically interposed in the inner space of the restraint portion, Conversely, when the locking part is lowered, it deviates from the internal space of the restraining part and releases the fixing force with the insertion part.

In order to separate the auxiliary hose from the main hose as described above, the locking portion 220 of the connection body 200 is lowered from the restraining portion 213 to separate the restraining portion and the insertion portion 111. When separated in this way, the main body (100) remains in the main hose, and the connection body (200) remains in the auxiliary hose. When reconnected later, the main hose and The auxiliary hose is connected immediately.

On the other hand, the fixture 213-2 is formed in a wedge shape and is exposed and released into the inner space of the restraint portion 213 through the through hole 213-1 to form a pressing portion ( 213-2a); and an elastic portion 213-2b that is bent at a right angle from the pressing portion and extends downward and is in close contact with the outer peripheral surface of the restraint portion, but is made of a curved surface perpendicular to the set and is caught on the inner diameter of the locking portion 220. .

And the locking portion 220 further includes a pressing piece 221 formed at a position corresponding to the fixing member 213-2 in the inner diameter. As described above, when the locking part 220 is raised and lowered on the restraining part 213, the pressing piece 221 gradually presses the curved surface of the elastic part 213-2b, and the pressing part 213-2a moves into the inner space of the restraining part. It is composed of principles that lead to entry into . Meanwhile, when the locking part 220 moves up and down on the restraining part 213, the elastic part 213-2b is forcibly brought into close contact with the restraining part by the pressing force of the pressing piece 221, and the locking part descends on the restraining part and presses. As the piece gradually escapes from the elastic portion, when the pressing force is released, the elastic portion that was in close contact with the restraining portion returns to its original state, and the pressing portion (213-2a) that entered the inner space of the restraining portion naturally leaves the inner space.

The spring 230 is vertically disposed on the upper side of the restraining portion 213, the lower side is mounted on the seating portion 212, and the pressing piece 221 of the locking portion 220 is stacked on the upper side. In this way, the spring 230 is contracted by the pressing piece 221 when the user lowers the locking part 220, forming an elastic force, and when the user removes the locking part from his hand, the contracted spring is tensioned and the locking part is automatically opened. Raise and return to original position.

In other words, the one-touch hose connector of the present invention includes a main body 100 that is tightened and coupled to the main hose for interconnection of the main hose and the auxiliary hose; and the main body 100 is connected vertically at the top and the hose is at the bottom. The coupled housing 210, the locking portion 220 that is overlapping and coupled to the outside of the housing and lifts or lowers by manual operation to restrain the main body, and is interposed between the housing and the locking portion to return the lowered locking portion to its original position. It consists of a connecting body 200 made of a spring 230 and tightened with the auxiliary hose. In the process of vertically interfering with each other, the main body and the connecting body are mutually detached depending on whether or not the position is constrained by side pressure, so that the auxiliary hose is connected. While allowing arbitrary extension or replacement of the main body 100, in particular, the edge of the main hose is inserted into the upper and lower inner space, and a protrusion 113a in the reverse direction is formed to protrude along the outer circumference of the fitted hose. It includes a frame 110 that prevents separation; and an operating unit 120 that is overlapping and coupled to the outside of the frame and pressurizes and fixes the main hose inserted into the protrusion. The frame 110 is made of a cylinder of a set diameter. An insertion portion 111 in which the upper part of the connection body 200 is connected by fitting, and a packing for preventing water leakage is interposed on the overlapping surface with the connection body; and a thread is formed along the outer circumference and protrudes upward with an expanded diameter compared to the insertion portion.
