Fixed element - a part equipped with a pin, when the lock is closed, forms a structural and functional integrity with the locking device.

Utility model - a lock for a rotary hatch of a vehicle (hereinafter referred to as a lock) is used to lock the hatch 20 in the closed position, closing the cavity in the vehicle, opened and closed by rotation relative to the axis of rotation 21 Fig. one.

The lock for the rotary hatch of the vehicle includes a fixed element 1, provided with a pin 3, and a locking device 2. The fixed element 1 can be installed on the body 22 near the circumference of the cavity to be closed, in this case the locking device is installed on the hatch in such a way that when the hatch is closed the slot 8 of the holder 6 covered the pin 3. The lock is opened and closed by a cylinder mechanism 5 passing through the hatch skin. Depending on the design intent, the installation locations of the fixed element and the locking device can be mutually changed.

When describing the utility model, the position of the elements of the locking device corresponding to the closed position is shown in Fig. 2, 3, 4 and open in Fig. 5, 6.

The finger 3 can be made in the form of a protruding axial pin having a cross-sectional shape of a circle or a polyhedron.

The locking device 2 is provided with a base plate 4, a rotary cylinder mechanism 5, a holder 6, a latch 8 and torsion springs 14, 15 (Fig. 2-6).

The support plate 4 is made with elements for attachment, for example, threaded holes 23.

In particular cases of execution, the base plate can be equipped with rigidly fixed support pins 16, 17, 18 to limit the movements of the latch in the open position, and the holder in the open and closed positions, respectively.

Rotary cylinder mechanism 5 is designed to open the lock, and is mounted on a base plate, one end 24 of the mechanism goes outside the hatch skin and is equipped with a suval element or a rotary handle to ensure rotation when opening or closing the locking device, and the other is equipped with a rotary leash 19.

The cylinder mechanism 5 can be made in the form of a shaft mounted in the sleeve of the base plate 4 on an interference fit, for example H7/g6, allowing the shaft to rotate under external force.

The holder 6 is mounted on the axis 7, rigidly fixed on the base plate 4, with the possibility of rotation. The holder 6 is made with a slot 8 to hold the finger in the closed position, with a thrust 25 and supporting 26, 27 surfaces.

The profile of the slot 8 of the holder is profiled in such a way that, when the hatch is closed, the pin of the fixed element enters the slot and, in contact with its contour, creates a force that rotates the holder to the closed position. 2-4. Profile profiling of the slot of the holder is carried out by the method of graphic design.

The latch 9 is mounted on the axis 11 rigidly fixed on the base plate 4 with the possibility of rotation.

The latch 9 is made in the form of a rocker, at one end with a stop 10 for contact with the stop surface 25 of the holder 6, in order to lock the holder 6 in the closed position and shoulder 12 on the other. The shoulder is provided with a pressure surface 13 for contact with the leash 19 of the cylinder mechanism when the lock is opened and a supporting surface 28.

, в направлении перемещения держателя 6 из закрытого в открытое положение, а фиксатора 9 из открытого в закрытое, соответственно.Torsion springs 14, 15, create moments of force

, in the direction of movement of the holder 6 from the closed to the open position, and the latch 9 from the open to the closed position, respectively.

Springs 14, 15 can be wound from steel wire, for example B-2A according to GOST 9389-75 Carbon steel wire, spring. Specifications, put on the axis and sealed with one end on the support plate, and the other on the surface of the holder and retainer, respectively.

In the case of installation, the support pins 16, 17, 18 limit the movement of the latch in the open, and the holder 6 in the open and closed positions, by contact with the supporting surfaces 26, 27, 28, which can be made in the holder 6 and the latch 9 to abut against these pins when they are in their extreme positions, respectively.

The utility model works as follows

When the hatch 20 is open, the elements of the locking device are in the open position Fig. 5, 6.

If an appropriate support pin is installed, the holder 6 is supported by the support surface 26 in the pin 17, which limits its movement caused by the moment of force from the torsion spring 14, and the latch 9 can be supported by the support surface 28 in the pin 16, which limits its movement in the open position caused by rotation leash 19 of the cylindrical mechanism to the open position.

, стремящейся удержать держатель в положении открытия, поворачивает держатель в положение закрытия Фиг. 2-4.When the hatch is turned to close, the pin 3 of the fixed element enters the slot 8 of the holder and, when the pin moves in a straight line relative to the base plate 4, due to contact with the surface of the profile contour of the slot 8, it creates a force that overcomes the moment of force of the torsion spring 14

, tending to hold the holder in the open position, rotates the holder to the closed position FIG. 2-4.

The location of the holder in the closed position, corresponding to the closed position of the hatch, is provided by the design study of the lock elements and its installation on the vehicle.

When the hatch is closed, the cylinder mechanism rotates until the leash 19 turns to the closed position, at which its power contact with the pressure surface 13 of the latch arm stops.

пружины кручения 15, фиксатор поворачивается в положении закрытия Фиг. 2-4, при этом упор 10 фиксатора входит в контакт с упорной 25 поверхностью держателя и предотвращает его поворот в положение открытия.Under the influence of the moment of force

torsion springs 15, the latch rotates in the closed position Fig. 2-4, the stop 10 of the latch comes into contact with the stop surface 25 of the holder and prevents it from rotating to the open position.

Further rotation of the holder 9 in the closing direction, caused by the moment of force of the spring 15 moving the latch 9 to the closed position, can be limited, if appropriately installed, by the support pin 18 coming into contact with the bearing surface 27 of the holder.

Elements of the locking device are transferred to the closed position Fig. 2-4.

The profiles of the contact surface of the retainer stop 10 and the support surface 25 of the holder are determined by the graphic design method in order to prevent the holder from rotating when external loads are applied, for example, from moving a finger with an allowable deformation of the structure.

If it is necessary to open the lock, turn the cylinder mechanism in the direction of opening, while the leash 19 turns and comes into contact with the pressure surface 13 of the latch arm 12 and, overcoming the moment of force from the spring 15, turns the latch in the direction of the opening position Fig. 5, 6, while the stop 10 comes out of contact with the stop 25 surface of the holder.

The movement of the latch 9 in the direction of opening may be limited, if appropriately installed, by the support pin 16 coming into contact with the bearing surface 28 of the latch.

от пружины сжатия 14, держатель 6 поворачивается в направлении положения открытия. Перемещение держателя 6 может быть ограниченного опорным штифтом 17, входящим в контакт с опорной поверхностью 26.Under the action of force, from the movement of the finger 3 relative to the base plate, transmitted to the contour of the slot 8 at the point of contact and the moment of force

from the compression spring 14, the holder 6 rotates in the direction of the opening position. The movement of the holder 6 may be limited by the support pin 17 coming into contact with the support surface 26.

Elements of the locking device are transferred to the opening position Fig. 5, 6.

Since in the proposed technical solution, the design of the latch is simplified and the compression springs are replaced by torsion springs, the achievement of the technical result is de-energized - the simplification and reduction in the dimensions of the structure.
