Abstract
The invention belongs to the technical field of aircraft structures and relates to a quickly-disassembled rotary opening cover lock. The quickly-disassembled rotary opening cover lock comprises a lock seat, a lock tongue, a special-shaped pin, a spring and a steel ball. The lock tongue is connected to the lock seat through the special-shaped pin. The steel ball and the squeezed spring are installed in an annular groove of the lock seat. One side of the steel ball abuts against a groove of the lock tongue, and the other side of the steel ball makes contact with the squeezed spring. According to the quickly-disassembled rotary opening cover lock, an opening cover can be quickly opened and locked, the size of a lock body is small, and meanwhile the damage to the structure of the opening cover is small; the quickly-disassembled rotary opening cover lock can be applied to aircraft bodies, missile pylons and other skin opening covers.
Description
Technical field
The invention belongs to aircaft configuration technical field, relate to a kind of quick-release type and rotate lid lock.
Background technology
Lid is the requisite a kind of structure member of aircraft, and in lid, mostly installing port cover lock realizes the quick opening and closing of lid. It is big that current lid locks mostly volume, is unfavorable in small-sized lid and installs, and needing the big opening of lid is installed, lid structural strength is caused destruction by this simultaneously. The lid lock jerky effort of opening and closing, is not easy to operation simultaneously.
Summary of the invention
It is an object of the invention to: propose a kind of quick-release type and rotate lid lock, simple in construction, easy to use, it is simple to use in small size lid.
The technical scheme is that a kind of quick-release type rotates lid lock, including:
Lock (1), dead bolt (2), abnormity pin (3), spring (4) and steel ball (5);
Lock (1) top is the cuboid-type of one end lower bands jagged (11), and lock (1) bottom is square plate structure; The part of breach (11) is just had small sircle hole (13) by lock (1) top; Lock (1) corner, bottom has circular hole (15), lock (1) bottom and lock (1) top small sircle hole (13) coaxial position are provided with big hole (12), having the elongated slot (14) that two ends are circular in the middle of lock (1) bottom face, breach (11) is just connected by described elongated slot (14) and lock (1) top; Dead bolt (2) is middle with the rectangle having an area of hole (22) with a few font breach (23) with sphenocephaly (21) other end for one end; It is cylindrical with the abnormity of flat recess (32) with thin cylinder (33), the middle cylinder (31) that eliminates with both sides, bottom that abnormity pin (3) is a top; Spring (4) is normal spiral spring shape, and steel ball (5) is for spherical;
Dead bolt (2) is connected on the breach (11) of lock (1) by abnormity pin (3), dead bolt (2) can rotate within the specific limits around the axis of abnormity pin (3) under the drive of abnormity pin (3), spring (4) and steel ball (5) are arranged in lock (1) bottom elongated slot (14), steel ball (5) side and spring (4) end thereof contacts, opposite side contacts with a few font breach (23) of dead bolt (2).
The invention have the advantage that quick-release type of the present invention rotates lid lock construction simple, volume is little, it is reliable, easy to operate to lock, and can install and use in small size lid, and service life, factory, greatly improved lid lock ease for use, reliability.

Detailed description of the invention
Below the present invention is described in further details.
The technical problem to be solved in the present invention is: solving current lid, to lock mostly volume big, is unfavorable in small-sized lid and installs, and needing the big opening of lid is installed, lid structural strength is caused destruction by this simultaneously. The lid lock jerky effort of opening and closing, the problem being not easy to operation simultaneously.
Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5. Quick-release type of the present invention rotation lid lock includes: lock 1, dead bolt 2, abnormity pin 3, spring 4 and steel ball 5;
Lock 1 top is the cuboid-type of one end lower bands jagged 11, and lock 1 bottom is square plate structure; The part of breach 11 is just had small sircle hole 13 by lock 1 top; Corner, lock 1 bottom has circular hole 15, and lock 1 bottom and lock 1 top small sircle hole 13 coaxial position are provided with big hole 12, has the elongated slot 14 that two ends are circular in the middle of lock 1 bottom face, and breach 11 is just connected by described elongated slot 14 with lock 1 top; Dead bolt 2 is that one end is middle with the rectangle having an area of hole 22 with a few font breach 23 with sphenocephaly 21 other end; It is cylindrical with the abnormity of flat recess 32 with thin cylinder 33, the middle cylinder 31 that eliminates with both sides, bottom that abnormity pin 3 is a top; Spring 4 is normal spiral spring shape, and steel ball 5 is spherical;
Dead bolt 2 is connected on the breach 11 of lock 1 by abnormity pin 3, dead bolt 2 can rotate within the specific limits around the axis of abnormity pin 3 under the drive of abnormity pin 3, spring 4 and steel ball 5 are arranged on bottom lock 1 in elongated slot 14, steel ball 5 side and spring 4 end thereof contacts, opposite side contacts with a few font breach 23 of dead bolt 2.
