Description

The invention relates to the field of engineering, and more particularly to devices for holding and uncoupling various objects with each other and can be used, for example, for aircraft (helicopters) for external suspension, transportation and uncoupling of loads, for test equipment (shock stands), as well as for shipbuilding in the field of rescue equipment.

Known locks used for transporting and uncoupling suspended goods, for example, patent RU 2429164, B64D1 / 02, priority 05.06.2010, patent RU 2081792, B64D1 / 02, priority 02.03.1994

From patent RU 20817892, class B64D 1/02, published on 06/20/1997 (the closest analogue), there is a self-locking lock used for transportation and uncoupling and comprising a housing with spring-loaded brackets pivotally connected to the rod, a lever and a latch made with protrusions interacting with leaf springs coaxially mounted with the protrusions on the housing.

The disadvantages of this self-locking lock are: the presence of a complex kinematically connected system of levers and for this reason large dimensions and mass, the presence of coil springs of different nomenclature difficult to manufacture, the absence of an alarm for the open position of the lock.

The technical problem, the solution of which the invention is directed, is to create a device design for holding and uncoupling the object, which allows to obtain a technical result, which is manifested in increasing the reliability of the device, simplifying the design, reducing the manufacturing cost, reducing the number of incoming parts and overall dimensions.

Obtaining the specified technical result is achieved using the inventive device for holding and uncoupling the object, consisting of an eye, acting as a body and containing a structural element for holding directly the device itself, the supporting and supporting surfaces for installing the remaining structural elements, as well as the reciprocal ear, balls, a locking shaft combined with a lever.

The essence of the proposed technical solution is illustrated by drawings, where figure 1 schematically shows a General view of a device for holding and uncoupling an object in a closed state (with a suspended object) with two balls and the corresponding number of holes and grooves under them;

figure 2 embodiment of the same device with n-number of balls and the corresponding number of holes and grooves under them;

figure 3 a device for holding and uncoupling an object with a lowered lever and, associated with it, a turning shaft locking;

in Fig.4 the same device with balls, driven into the grooves of the shaft of the locking, rotated ear turning;

figure 5 the same device after uncoupling the object.

The inventive device for holding and uncoupling an object consists of the eye of the main 1, on which the eye of the rotary 2, the locking shaft 3, the balls 4, the lever 5 are placed.

In the holes B of the eye of the main 1, between the eye of the swivel 2 and the locking shaft 3, balls 4 are enclosed.

The locking shaft 3 and the lever 5 are connected to each other and are a single unit. The locking shaft 3 is inserted into the Central hole of the eye of the main 1 and can rotate freely in it. On the surface of the locking shaft 3 there are grooves B with inclined surfaces, which, when combined with the holes B of the eye of the main 1 (Fig. 3), allow the balls 4 to move to the center of the locking shaft 3, and when the locking shaft 3 rotates to the initial state, the inclined surfaces of the groove B push balls 4 back.

The image of the principle of operation for clarity is shown only with two balls 4, holes B and grooves A and B, but n can be used in the design - the number of these elements as shown in figure 2. The number n depends on the geometric dimensions of these elements and the requirements for the loads they perceive.

In the initial state (Figure 1), an object 6 is enclosed between two ears 1 and 2, which acts on a device for holding and uncoupling the object with a force F. Balls 4 enclosed in the hole B of the eye of the main 1 between the groove A of the eye of the swivel 2 and the cylindrical surface the locking shaft 3 does not allow the swivel ear 2 to turn and release the object 6.

When combining the grooves B of the shaft of the locking 3 and the holes B of the eye of the main 1 (Figure 3), the object 6, under the action of the force F, starts turning the eye of the swivel 2, which in turn pushes the balls 4 into the grooves of the shaft of the locking, which does not interfere with its cylindrical surface rotation of the swivel eye (Figure 4).

Full detachment of the object from the device for holding and uncoupling the object is shown in Fig.5. To return the device for holding and uncoupling the object to its original state, it is necessary to bring the object 6 between the dilated ears 1 and 2, close them and put the lever 5 in a vertical position.

Open or closed the device can be determined by the position of the lever 5.

Thus, the claimed device allows structurally simple to carry out the retention and uncoupling of an object with various dimensions with minimal material costs.

Claims (1)

A device for holding and uncoupling an object consists of a main eye, a swivel eye, a locking shaft, balls and a lever, while the locking shaft and the lever are connected to each other and are a single unit, while the locking shaft is inserted into the central hole of the main eye and can freely rotate in it, while on the surface of the locking shaft grooves are made with inclined surfaces, which, when combined with the holes of the main eye, allow the balls to move to the center of the locking shaft, thereby ensuring the possibility of turning the eye of the swivel, and when the shaft of the locking is turned to its initial state, the inclined surfaces of the groove push the balls back, while when the shaft of the locking is in the initial position, the balls are located in the holes of the ear of the main between the groove of the eye of the swivel and the cylindrical surface of the locking shaft, thereby not allowing the swivel ear to crank.
