The plug-in mechanism is designed on the transmitting cylinder and used for ensuring reliable storage and transportation connection and transmitting separation of the falling connector.

According to the separation movement direction, the plug-in mechanism can be divided into an axial plug-in mechanism and a radial plug-in mechanism; according to the source of separating force, the plugging and unplugging mechanism can be divided into an active unplugging mechanism driven by electromagnetic, hydraulic, motor and the like and a passive unplugging mechanism which enables the shedding connector to be separated by the axial movement of the projectile body and the thrust of the engine during the missile launching, and the like are common shearing type separating mechanisms, four-bar linkage separating mechanisms, direct pulling and unplugging mechanisms and the like. The axial plug-in type socket is required to be installed by protruding a bulge on the projectile body, occupies the radial space of the launching cylinder, is not beneficial to the miniaturized design of the barrel-mounted missile and is rarely adopted; the active pulling-out type chain length transmission is complex in mechanism and lower in reliability compared with a passive separation type chain length transmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail by the following detailed description with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

The embodiment provides a plug mechanism for a small barrel-type launching missile, which has simple structure and reliable performance, and ensures that a barrel-type missile falling connector is reliably plugged during storage and transportation and is safe and reliable to separate during launching.

As shown in fig. 1 to 3, the inclined slide rail type radial plug mechanism includes: the device comprises a support 1, a guide seat 2, a drop plug 3, a drop-in reed 4 and a reed bracket 5; the support 1 is fixed on the transmitting cylinder, two symmetrical inclined slide rails are arranged on the support 1, namely, two right trapezoid vertical plates which are parallel to each other and have the same structure are arranged on the surface of the support 1, the inclined edges of the right trapezoid vertical plates are used as the inclined slide rails, and the inclined direction of the inclined slide rails is obtained after the inclined slide rails incline upwards by a set angle along the axial direction of the transmitting cylinder. As shown in fig. 3, the inclination angle of the inclined slide rail is alpha, the value range of the inclination angle alpha is generally 25-35 degrees, and the inclination angle alpha can be comprehensively selected according to factors such as the separation stroke of the falling connector, the radial space of the transmitting cylinder and the like. The smaller the inclination angle α, the smoother the separation process, but the larger the corresponding separation stroke.

The upper end of the guide seat 2 is provided with two inclined slide ways, the lower surfaces of the two inclined slide ways are respectively in sliding fit with the two inclined slide rails on the support 1, namely the guide seat 2 can slide upwards along the inclined slide rails on the support 1; the lower end of the guide seat 2 is fixedly connected with the drop plug 3, so that the drop plug 3 is driven to slide when the guide seat 2 slides along the inclined slide rail. The drop plug 3 is radially connected with the drop socket at the upper end of the missile (namely, the connection direction of the drop plug 3 and the drop socket is along the radial direction of the missile). The guide seat 2 drives the drop plug 3 to slide along the inclined slide rail, so that the axial motion of the missile can be converted into the radial motion of the drop plug 3 (the sliding along the inclined slide rail is the combined motion of the radial motion and the axial motion, and compared with H0 and H1 and L2 in FIG. 4).

The drop plug 3 is provided with two asymmetric guide pins 7 which have the functions of separating and guiding with the drop socket and preventing misplug; the length of the guide pin 7 is slightly larger than that of the connector pin, so that the function of protecting the pin and separating and guiding in the separation process can be achieved; the diameters of the two guide pins 7 are different, and the anti-misplug function is achieved.

The upper surface of the inclined slide way at the upper end of the guide seat 2 is provided with continuous steps, and each inclined slide way is matched with one release and insertion reed 4 and is used for compressing and limiting the guide seat 2; specific: the support 1 is connected with a reed bracket 5 through a connecting screw 6, one end of the inserting and removing reed 4 is connected with the reed bracket 5, and the other end is pressed on the step of the corresponding inclined slideway, so that the guide seat 2 is pressed by the inserting and removing reed 4.

The plug-out reed 4 plays a role of pressing the limiting guide seat 2 (the plug-out plug 3), and when in storage and transportation, the plug-out reed 4 presses the plug-out plug 3 on the elastomer through the pressing guide seat 2 (namely, ensures the reliable connection between the plug-out plug 3 and the plug-out plug on the elastomer); and when the device is launched, the continuous steps on the guide seat 2 are propped against, so that the guide seat 2 is prevented from rebounding and interfering with the subsequent elastomer. The sum of the pressing force of the release spring 4 and the inserting and pulling force of the release connector is larger than the maximum overload force during storage, transportation and carrying of the barreled missile, so that the limit reliability can be ensured, and the pressing force mainly depends on the width, the thickness and the initial deformation of the release spring 4.

The plug-in mechanism is installed manually and automatically separated along with the movement of the missile during launching. During storage and transportation, the cylindrical guided missile has vibration and impact environments, and the guide seat 2 is pressed on the missile through deformation of the two plugging-out reeds 4 on the basis of controlling plugging-in and unplugging force of the plugging-out connector. Meanwhile, the clearance between the guide seat 2 and the support 1 is reasonably controlled, so that the loose of the falling plug 3 and the falling socket on the bullet is prevented; after the firing, the missile moves along the axial direction of the firing barrel, and after the clearance between the support 1 and the guide seat 2 is eliminated, the falling plug 3 moves along the inclined guide rail of the support 1, so that the falling connector is separated.

As shown in fig. 4, during launching, the missile drives the drop plug 3 to move axially along the launching tube, and due to the limit of the inclined slide rail on the support 1, the guide seat 2 enables the drop plug 3 to move along the inclined slide rail, namely, the inclined slide rail enables the drop plug 3 to move radially through the axial movement of the missile, and then the drop plug 3 is separated from the drop connector; meanwhile, the continuous step design of the guide seat 2 is adopted, the drop plug 3 is limited by the drop-out reed 4, and the rebound of the drop plug 3 is prevented from interfering with the subsequent elastomer. The falling plug 3 moves under control and has definite track in the process of launching and separating, and the missile moves to separate the falling plug 3 automatically.

The foregoing is a further detailed description of the invention in connection with specific embodiments, and it is not intended that the invention be limited to such description. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
