Groove She You not be had on the inside of step type connecting rod A and step type connecting rod B, stepped connecting rod A and stepped connecting rod B, made
The both ends of dynamic cylinder push rod are respectively engaged on the groove of stepped connecting rod A and stepped connecting rod B.Pressurized strut push rod left upper portion is solid
Determine connecting spring A, the lower part of spring A is connected with pressurized strut push rod left upper portion, and the upper end of spring A is recessed with stepped connecting rod B's
Slot connects.The right end of pressurized strut push rod is connected on the inside of stepped connecting rod A, groove left end and stepped connecting rod B inboard groove phase
Away from a distance, passes through pin A respectively in the upper end of stepped connecting rod A and stepped connecting rod B and is connected with one end of connecting rod B,
The other end of connecting rod B is connected by pin B with one end of connecting rod A.The other end of connecting rod A is fixed on vee tail by pin C
Movable end inside.The movable end of vee tail is flexibly connected with the fixing end of vee tail by fixed hinge, vee tail
Fixing end is located on the outer wall of cabin.The ascending track two sides of T-type empennage inside cabin, have groove, in groove
Interior fixed spring B, one end of spring B are connected with the inner wall of groove, the fixed spacing ball of the other end of spring B.The outer diameter of spacing ball
Less than the internal diameter of the circular groove on T-type empennage side wall.
In the use of the present invention, gunpowder explosion generates thrust in pressurized strut, piston push rod drives T-type empennage to be unfolded upwards,
Upper end pushes the groove on the inside of stepped connecting rod A in contact, constraint of the stepped connecting rod A in slideway on the right side of push rod simultaneously
Under move up through link mechanism drive right side vee tail expansion, push rod move upwards on the left of a period of time rear push-rod put down
Platform is contacted with stepped connecting rod B inboard groove, and is buffered by spring, the left side vee tail under the drive of link mechanism
It starts to spread out, two vee tails and T-type empennage do not collide mutually during expansion.Circular groove rises on T-type empennage side wall
Certain position, spacing ball, which is pushed in T-type empennage side wall circular groove under the action of spring B, realizes locking, T-type tail after locking
Wing position is fixed from generation movement, and push rod and T-type empennage lower end are connected and pass through push rod both ends platform and block stepped connecting rod
A, two vee tails of B and then locking left and right.
The invention has the following advantages over the prior art: the advantages of combining vee tail and T-type empennage, utilizes V-type
Empennage reduces the lateral dimension of guided missile, and the storing space of guided missile is saved convenient for storage, transport and transmitting, increases storing dress
The storage capacity set, T-type empennage increase whole controllability, and transport space can be saved by, which having reached, mitigates overall weight,
Control performance can be enhanced again, realize that the expansion of two kinds of empennages reduces the weight of guided missile entirety using a pressurized strut.Utilize rank
The boss height difference of ladder type push rod realizes that the delay of two vee tails is unfolded by push rod.
