Utility Model Implementation

The quick lock coupling device is a connector or carabiner. In FIG. 1-6, 8 shows that the claimed connector includes the following elements (parts) in its design: a hollow cylindrical body (1), a thrust element (2), a locking cylindrical element (3), a thrust liner (4), a fixing piston (5 ) and spring (6). All the above elements (parts) are connected and form a single structure - the product. In addition, all of the above elements (parts) are functionally interconnected, which ensures the operability of the connector.

In FIG. 1 shows a General view of a hollow cylindrical body (1). The hollow cylindrical body (1) is a hollow cylinder (sleeve), open from both end ends to accommodate the corresponding elements of the connector. The hollow cylindrical body (1) on one side (11) has guide grooves (17) with restrictive chamfers (18) on the inner surface (10). The area occupied by these grooves and chamfers ranges from 10 to 30% of the total area of the inner surface of the cylindrical body (1). On the other hand (opposite side) of the cylindrical body (1), the inner surface is smooth to ensure effective sliding of the thrust element (2), which is installed in the internal volume of the cylindrical body (1) with the possibility of its movement in the longitudinal direction.

The stop element (2), as shown in FIG. 2, is a cylindrical part in the form of a sleeve with an annular chamfer and a cylindrical cavity, which is open from only one end side. Moreover, the other end side of the thrust element is closed and serves as a supporting element for parts of the connection and disconnection mechanism. The movement of the thrust element (2) inside the volume of the cylindrical body (1) is limited on the one hand by the fixing cylindrical element (3), and on the other hand, by the protrusions formed by chamfers and grooves. A spring (6) is installed in the internal cavity of the thrust element, which abuts against the inner surface of the end wall, the flat supporting part (7), with one end (one of its sides). And with its other end it abuts against the support insert (4), which is a washer with a central cylindrical protrusion, in which a hole is provided for installing any elements in it for connecting the claimed device with elements of consumer products. For example, a key ring may be inserted into this hole. The diameter of the washer may be less than the inner diameter of the cylindrical body (1), in which case the washer may enter the inner cavity of the cylindrical body (1). Moreover, the spring (6) works in compression and provides the possibility of elastic mechanical connection between the support insert (4) and the thrust element (2). In the case where the diameter of the washer is comparable to the outer diameter of the cylindrical body (1), the washer is rigidly fixed relative to the cylindrical body (1) by a fixing cylindrical element (3). The diameter of the liner may have a smaller diameter than the diameter of the inner cylindrical cavity of the cylindrical body (1), which ensures the mobility of the liner in the internal volume of the cylindrical body (1). For example, the liner (4) with this method of placement has the ability to rotate around its axis in the volume of the cylindrical body (1). In this case, the fixation of the liner (4) is provided on the one hand by a locking cylindrical element (3), and on the other hand, the liner (4) is spring-loaded by a spring (6).

The locking cylindrical element (3) is a cylindrical part, on one end of which there is an open cylinder cavity, and on the other there is an end wall with a central through hole (12) to allow the central cylindrical protrusion (13) of the supporting insert (4) ) Moreover, the Central cylindrical protrusion (13) contains a hole (14) for fixing relative to the elements of clothing or connecting elements. In any of the options, the locking cylindrical element (3) is mounted relative to the outer surface of the cylindrical body (1). Moreover, the inner diameter of the cylindrical element (3) is made larger than the outer diameter of the cylindrical body (1), to ensure pairing of part of the outer surface of the cylindrical body (1) and part of the inner surface of the cylindrical element (3). The cylindrical element (3) is fixed relative to the cylindrical body (1) by a threaded connection, i.e. the cylindrical element (3) can be screwed onto a part of the cylindrical body (1).

The fixing piston (5) is a complex part with a cylindrical working part, on which polyhedral protrusions (9) are mounted on one side and an annular stop with a diameter exceeding the diameter of the cylindrical working part of the fixing piston (5). On the end surface of the annular stop there is a central cylindrical protrusion (15) with an opening. This protrusion has a function similar to that of the protrusion of the support insert (4). Those. this protrusion with a hole is an element for which or to which an element of a consumer product, the product itself or a part thereof can be attached. For example, a ring with a bunch of keys can be inserted into the hole of the cylindrical protrusion on the piston (5), and a ring can be inserted into the hole of the protrusion on the insert (4), which is fixed in turn to the garment element.

The locking piston (5) contains an end support region (8), which is in contact with the flat support part (7) of the stop element (2),

The working part of the fixing piston is inserted into the cylindrical body from the side where there are guide grooves and restrictive chamfers. In this case, the protrusions (9) of the fixing piston, representing multifaceted elements, are in contact with the guide grooves and when the piston is pressed (for example, by applying a hand in the longitudinal direction of the cylinder to overcome the compression force of the spring), the protrusions fall into the grooves whose curved surfaces allow the piston to move, as in the longitudinal direction, and provide its rotation at an angle determined by the design of the grooves and protrusions. When the protrusions reach the corresponding point in the grooves, the protrusions slide along the guide surfaces into the corresponding restrictive chamfers and are fixed in them due to the force exerted on the piston by the thrust element (2), which in turn is affected by the spring force (6). When the piston (5) is pressed again, the protrusions come out of the restrictive chamfers (grooves) and slide along the groove guides so that they rotate through the angle and the direction of the protrusions towards the guides, providing a free exit of the fixing piston (5) from the inner space of the cylindrical body (1) .

On. FIG. 7 shows an example implementation of the claimed device. The claimed connecting device can, for example, be fastened with one part to the elements of clothing, and the other to hold an object: keys, a casing or a holder for bottles, etc.

In FIG. 8 shows a section through a cylindrical body (1). As can be seen in the drawing, the inner walls (surfaces) of the cylindrical body are provided with guide grooves (17) of a zigzag shape that contain restrictive chamfers (18). The outer surface of the cylindrical body (1) is provided with a thread (16) on one outer side for screwing the fixing cylindrical element (3).

In FIG. 9 shows the movement pattern of the protrusions (9) along the guide grooves (17) and the fixing of the protrusions in the restrictive chamfers (18). Each protrusion moves in its groove and is fixed in its restrictive chamfer. The working pattern of each protrusion is similar. As can be seen from the diagram, the protrusion (9) is a polyhedron, the five faces of which are working, i.e. interact with the walls of the guide grooves by sliding. So, at the entrance of the protrusion into the guide groove, one face works - it slides all the way along the groove wall, then, under the action of the spring on the piston, the protrusion moves downward, sliding along the other wall of the groove. Next, the protrusion falls into the boundary chamfer (18).

The presence of chamfers, a spring mechanism with a thrust element and a liner, grooves, protrusions of a multifaceted shape provides a quick movement of the piston with its subsequent fixation relative to the cylindrical body, which leads to the achievement of the specified technical result, namely, reducing the time of connection and disconnection of various kinds of consumer products or their components (increasing the efficiency of the connecting locking device).
