The locking stability of the push type self-locking mechanism can be improved by arranging the locking groove 25, and the male head 6 is prevented from moving rightwards due to vibration when being locked with the claw buckle 5, so that the male head 6 is separated from the claw buckle 5.
In a second aspect, the present invention provides a closure, in combination with fig. 14, the closure comprising: a first connecting piece 71, a second connecting piece 72 and the pressing type self-locking mechanism; the lock shell 1 is fixedly connected with the first connecting piece 71 through a fixing piece 13, and the male head 6 is fixedly connected with the second connecting piece 72 through a supporting plate 61. The first connecting member 71 may be a door frame, a box, a bracket, or the like, and the second connecting member 72 may be a door panel, a push plate, or the like. In this embodiment, the first connecting member 71 is a box, the second connecting member 72 is a door, and one end of the second connecting member 72 is pivotally connected to the first connecting member 71.
With reference to fig. 10, 11 and 14, the operation principle of the push type self-locking mechanism in the locking device is as follows:
when it is desired to lock the second connecting member 72 and the first connecting member 71 together, the inserting end 32 is located at the second clamping position 212, and the sliding block is located at the second working position. Firstly, the second connecting piece 72 is pressed towards the lock shell 1, so that one end of the male head 6, which is far away from the supporting plate 61, extends into the lock shell 1 through the opening and extends into the locking groove 25 to be abutted against the sliding piece 2; then, the second connecting element 72 is continuously pressed to move the sliding block backwards, that is, the sliding block is translated from the second station to the second rotation station, the inserting end 32 is moved from the second clamping point 212 to the second rotation point 214 through the second guiding post 33, in the process, the claw 5 swings rightwards relative to the sliding element 2 under the guiding action of the second guiding groove 172, that is, the claw 5 swings clockwise relative to the sliding element 2, and the first guiding post 52 moves from the second guiding groove 172 into the first guiding groove 171; when the sliding block moves to the second rotation point 214, that is, the sliding member 2 moves to the second rotation station, the pressing of the second connecting member 72 is stopped, at this time, the sliding block moves to the first station by the second rotation station under the action of the elastic member 4, that is, the sliding block moves forward, and the plugging portion moves to the first clamping point 211 from the second rotation point 214; when the sliding block moves to the first working position, the claw buckle 5 and the male head 6 are in locking connection, so that the second connecting piece 72 cannot move away from the first connecting piece 71.
When the second connecting element 72 needs to be separated from the first connecting element 71, the inserting end 32 is located at the first clamping point 211, and the sliding block is located at the first station. Firstly, pressing the second connecting piece 72 towards the lock case 1 to move the sliding block backwards, i.e. the sliding block is translated from the first station to the first rotation station, the inserting end 32 is moved from the first clamping point 211 to the first rotation point 213 through the second guiding column 33, in the process, the claw 5 swings leftwards relative to the sliding piece 2 under the guiding action of the second guiding groove 172, i.e. the claw 5 swings anticlockwise relative to the sliding piece 2, and the first guiding column 52 moves towards the front end of the movement of the second guiding groove 172; when the sliding block moves to the first rotation point 213, that is, the sliding block 2 moves to the first rotation station, the second connecting member 72 stops being pressed, at this time, the sliding block moves from the first rotation station to the second station under the action of the elastic member 4, that is, the sliding block moves forward, and the plugging part moves from the first rotation point 213 to the second plugging point 212; when the slide block is moved to the second position, the claw catch 5 is disengaged from the male part 6, so that the second connection member 72 can be moved away from the first connection member 71, and the male part 6 can be removed from the lock housing 1.
In this embodiment, the front-back length of the push type self-locking mechanism in the locked state is 41 mm, the up-down height is 8 mm, and the left-right length is 30 mm. The push type self-locking mechanism has simple structure and convenient assemblyThe vibration response test has the characteristics of convenience in installation, long service life, firm and stable locking, high space utilization rate and the like, and can meet the requirements of a vibration response test with a severe Bm level (the vibration amplitude is 3mm when the frequency f is less than or equal to 9Hz, and the acceleration is 10m/s when the frequency f is more than 9-200 Hz2Vibration of (2) and its fatigue life is greater than 1000 times.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
