Description

The utility model relates to transport, and concerns the protection of a vehicle against unauthorized use.

It is known “DRAGON” DEVICE FOR PREVENTION OF UNAUTHORIZED USE BY THE TRANSPORT MEANS ”PM RU 20892 [1], which contains a locking pin for interaction in working position with the vehicle body, with a locking mechanism located inside the locking pin on the end side, with a locking pin and a locking pin, and a locking pin with a locking pin and a locking pin. to the steering shaft of the coupling, with a recess for the stopper made in it, provided with a spring installed in a shaped curly with an orienting lip. The axis of the lock coincides with the axis of the pin.

A disadvantage of the known construction is the complexity of the installation of the device, the unreliability of mounting the coupling on the steering shaft. In fact, the steering wheel can be turned without opening the lock, which leads to the possibility of theft and low reliability of the device.

Closest to the claimed technical solution is “A DEVICE FOR PREVENTION OF UNAUTHORIZED USE OF A VEHICLE.” PM RU 113217 [2], containing a lock with a mechanism of secrecy, consisting of a stationary cylindrical body and a movable unit located inside the fixed case, the mobile unit is connected with a locking mechanism, consisting of a stationary cylindrical body and a movable unit located inside the stationary case, the mobile unit is connected with a locking mechanism, which consists of a stationary cylindrical body and a movable unit located inside the stationary case, the mobile unit is connected to a locking mechanism, which consists of a stationary cylindrical body and a movable unit located inside the fixed case, the mobile unit is connected to a locking mechanism, which consists of a stationary cylindrical body and a mobile unit located inside the stationary case, the mobile unit is connected to a locking device, which consists of a fixed cylindrical body and a movable unit located inside the fixed case. by means of a flexible thrust placed in a protective casing, the lock case being rigidly connected to the front part of the protective casing, and on the opposite side from the lock located on the housing latch bolt, coupled to a respective end of the flexible rod. The end of the flexible thrust opposite the bolt is connected to the movable block of the lock by means of a rocker mechanism, and the axis of the cylinder of the lock is perpendicular to the axis of the protective casing part.

A disadvantage of the known device is low reliability due to the presence of the rocker mechanism. The disadvantage is also a narrow scope associated with a limited course of the locking bolt, driven by a rocker mechanism. The disadvantage also lies in the complexity of monitoring the status of the device.

The technical result of the proposed utility model is to increase the reliability of the device, expanding the scope, increasing the possibility of visual control of the device state.

The technical result is achieved in that a device for preventing unauthorized use of a vehicle (anti-theft device), containing a lock with a secrecy mechanism, consisting of a fixed cylindrical body and a movable block (containing a cylindrical larva, in which a mechanical key is inserted into the cylinder end, and the secret part blocks movement movable body in the absence of a key with the required set of projections), located inside the fixed body, movable The lock is connected to the locking bolt by means of a flexible thrust (for example, in the form of a thermally unprocessed extension spring) housed in a (rigid) protective casing (serving for mechanically rigid connection of all parts of the device), and the lock body is rigidly connected to the end of the protective casing (for example , welding), and on the opposite end of the lock of the protective casing there is a locking bolt (for example, in the form of a cylindrical pin inserted into the end of the casing of the flexible rod) connected to the corresponding end of the flexible rod thrust (for example, by pressing the end of the flexible thrust into the locking bolt) is characterized by the fact that the end of the flexible thrust opposite the bolt is rigidly connected to the movable block of the lock’s secrecy mechanism (for example, by fixing in the adapter fixed on the movable block of the lock) , in the field of fastening of flexible thrust to the movable block of the lock, there is a return spring.

In the case of the lock, there may be a guide longitudinal groove, the axis of which is parallel to the cylinder axis of the case, and the movable block of the lock contains a protrusion that can be moved along the guide groove and with a fixing recess adjacent to the groove. The specified groove and the protrusion allows the movable unit to move along the cylinder axis of the body, and when the protrusion of the fixing recess is reached, when the movable unit rotates around the axis of the cylinder, it is fixed in it. Fixing the movable part of the lock (and, accordingly, the bolt) prevents accidental pressing of the larva during the movement of the vehicle.

The return spring may be conical. A conical spring can be installed between washers of different diameters, which reduces the number of additional parts of the device.

The lock may include a cylinder shaped retainer connected to the movable body unit and an opening in the fixed part of the body opposite the retainer in the locked position of the lock. The presence of the lock will reliably fix the movable block of the lock while maintaining the compactness of the device.

Additionally, there may be means of securing the device in the form of a plate with holes rigidly connected to the casing of the flexible rod. The configuration of the plate with holes can vary for use in various car interiors.

The device using the PP.1-5 Formula is shown in Fig 1 (section of the castle part) and Fig 2 (general view with a partial section), where:

1 - cylindrical case of the lock;

2 - movable block of the lock;

3 - locking bolt;

4 - flexible thrust;

5 - mobile casing guard;

6 - return spring;

7 - longitudinal groove;

8 - a ledge of the mobile block of the lock;

9 - locking recess;

10 - a clamp;

11 - an opening for a clamp in the motionless case of the lock;

12 - means of fastening the housing

The device to prevent unauthorized use of the vehicle acts as follows: The cylindrical body of the lock 1 connected to the protective cover of the movable link 5 and the fixing means 12 constitute the static part of the device that is fixed inside the vehicle body. The movable block of the lock 2 is connected to one end of the flexible thrust 4, the locking bolt 3 is connected to the other end of the flexible thrust. The axis of the lock coincides with the axis of the flexible thrust adjacent to the lock of the protective casing. The movement of the movable part of the castle has a rotational component around the axis of the castle and a translational component along the axis of the castle. When moving the movable block of the lock 2 into the body of the lock 1: the protrusion of the movable block of the lock 8 slides along the longitudinal groove 7, the return spring 6 is compressed, the flexible rod moves the locking bolt out. At the end of the movement, the lock 10 enters the hole for the lock 11, which corresponds to the "closed" position, the vehicle is blocked for movement. When opening the lock, the latch 10 emerges from the opening of the latch 11, the movable unit moves in the opposite direction, partially goes outside the lock body under the influence of the return spring 6. At the end of the movement, the protrusion of the movable block of the lock 8 enters the locking recess 9, which corresponds to the "open" position , with the vehicle unlocked for movement.

The device can be installed in any vehicle to block almost any control lever; it is enough to change the configuration of the means of fastening the hull to the existing geometric configuration of the cabin.

The technical result is an increase in the reliability of the device is achieved by the absence of a mechanism for converting rotational motion into translational, which reduces the number of parts in general, the number of rubbing parts and the number of situations leading to breakage (for example, the release of a lock cam from an eyelet loop, etc.)

The technical result - the expansion of the scope is achieved by obtaining the possibility of a wide variation of the length of the ledge of the bolt, which allows you to block most of the used control levers in modern cars.

The technical result is an increase in the ability to visually monitor the state of the device is achieved by the fact that in some cases when leaving the vehicle, however, it is possible to visually monitor the state of the device (locked or not) as the moving part of the lock (protrudes from the body or not). In the unlocked state, you can visually see the part of the movable block protruding beyond the limits of the cylindrical body, which can be given a contrasting color to improve visibility.

Industrial application. The utility model can be successfully used to produce reliable, universal devices to prevent unauthorized use of the vehicle (anti-theft devices).
