Embodiment

[0014] This embodiment is a locking mechanism for folding airfoils used in a certain type of guided ammunition.

[0015] figure 1 , figure 2 It is a schematic diagram of the structure of this embodiment.

[0016] The folding airfoil locking mechanism involved in this embodiment is composed of an airfoil shaft 1, a fixed pin 2, a tension spring 3, a locking pin 4, an airfoil 5, an unfolding spring 6, an opening retaining ring 7, and a rotating pin 8 , the airfoil 5 and the expansion spring 6 are inserted into the groove of the airfoil shaft 1, fixed by the rotating pin 8, so that the airfoil 5 can rotate around the rotating pin 8, and tends to the unfolded state under the action of the expanding spring 6; the rotating pin 8 Open retaining rings 7 are installed at both ends to ensure the positioning of the rotating pin 8; the fixed pin 2 passes through the two pin holes of the airfoil rotating shaft 1, and a tension spring 3 is connected to both ends; the locking pin 4 passes...

Abstract

A folding airfoil clamping locking mechanism mainly comprises an airfoil rotary shaft (1), a fixed pin (2), a tension spring (3), a locking pin (4), an airfoil (5), an unfolding spring (6), an openingblocking ring (7) and a rotary pin (8). The unfolding spring (6) pushes the airfoil (5) to rotate around the rotary pin (8) to the specific position. The tension spring (3) pulls the locking pin (4),thus the locking pin (4) is embedded into a limiting groove of the airfoil rotary shaft (1), and the airfoil (5) is located. According to the folding airfoil clamping locking mechanism, an existing folding airfoil clamping locking structure is simplified, the size and mass are reduced, cost is lowered, and the defects that an existing guided munition folding airfoil mechanism is large in size, high in mass and price and difficult to assemble are overcome.

Description

technical field [0001] The invention belongs to the technical field of guided munitions, in particular to a folding airfoil locking mechanism for guided munitions. Background technique [0002] At present, the commonly used airfoil folding methods in domestic guided munitions are: marble-type submerged folding mechanism and block elastic shaft-type folding mechanism, which are large in mass and volume, difficult to assemble, and complex in structure. Contents of the invention [0003] The object of the present invention is to provide a spring bayonet type folding airfoil locking mechanism in order to reduce the mass and volume of the existing airfoil folding mechanism of guided munitions, simplify the structure and reduce the cost. [0004] The folding airfoil locking mechanism involved in the present invention is composed of an airfoil shaft 1, a fixed pin 2, a tension spring 3, a locking pin 4, an airfoil 5, an unfolding spring 6, an opening retaining ring 7, and a rotat...
