A lock tongue 5 is vertically slidably disposed in the middle of the lock case 1. Through grooves 10 are formed on the left and right sides of the lock tongue 5 along the length direction of the lock tongue 5. A baffle 19 is provided on the side of the lock tongue 5 away from the lock case 1. In this embodiment, the baffle 19 is L-shaped, one end of which is opposite to the side of the lock tongue 5 away from the lock case 1, the other end of which is opposite to the bottom end of the lock tongue 5, and a telescopic spring 16 is provided on the other end of it. The end of the telescopic spring 16 away from the baffle 19 is connected to the bottom end of the lock tongue 5. The purpose is to enable the lock tongue 5 to be reset after moving. In this embodiment, four through holes 7 are formed on the baffle 19 and are arranged in two pairs diagonally. Four positioning holes 11 corresponding to the through holes 7 one by one are formed on the inner wall of the lock case 1 opposite to the baffle 19. The through holes 7 and the positioning holes 11 are connected and locked by positioning bolts (not shown in the drawing). The purpose is that the baffle 19 can be disassembled from the lock case 1 later.

[0026] An L-shaped support plate 8 is fixed to the side wall of the baffle 19. One end of the support plate 8 away from the baffle 19 is rotatably connected to a V-shaped dial 6 through a rotating rod 9. One end of the dial 6 away from the rotating rod 9 is located in the through groove 10 of the lock tongue 5. A linkage member is provided between the dial 6 and the extended end 4 of the handle 2. The linkage member includes a linkage piece 12, a linkage rod 13 rotatably connecting it to the lock case 1, and a driving block 14 provided at one end of the linkage piece 12 facing the lock tongue 5.

[0027] The linkage piece 12 is arranged in an irregular shape and is rotatably connected to the inner wall of the lock case 1 through the linkage rod 13. One end of the linkage rod 13 is in contact with the extended end 4 of the handle 2, and a driving block 14 is provided at the other end of it. It should be noted that the driving block 14 can adopt a cylindrical shape or a bent piece integrally formed with the linkage piece 12. The purpose is to contact the outer wall of one end of the dial 6 provided with the rotating rod 9. In this embodiment, the driving block 14 on the right is a cylinder, and the driving block 14 on the left is designed as a bent piece integrally formed with the linkage piece 12. A torsion spring 15 is sleeved on the outer wall of the linkage rod 13. The purpose is to enable the linkage piece 12 to be reset after moving. In this embodiment, two groups of linkage members are provided and are arranged oppositely at the left and right ends of the lock tongue 5.

[0028] A through sliding groove 17 is provided on the side of the baffle 19 away from the lock tongue 5. A T-shaped pull rod 18 is vertically slidably arranged at the sliding groove 17. One end of the pull rod 18 passes through the through groove 10 through the sliding groove 17, and the other end is located outside the lock housing 1. The purpose is to facilitate the personnel to drive the lock tongue 5 to move from the other end of the handle 2 on the lock housing 1, so that when in use, the door can be opened bidirectionally from inside and outside the installation object of this lock.

[0029] When the personnel install the lock, the lock tongue 5 needs to be installed upward. As Figures 1 to 3 shown, the front end of the lock tongue 5 is upward, the dial 6 is located on the right side of the baffle 19, the front end of the dial 6 is located in the through groove 10 of the lock tongue 5, and the driving block 14 on the linkage piece 12 at the same end as the dial 6 inside the lock housing 1 contacts the outer wall of the dial 6. At this time, when the personnel pull the handle 2, the handle 2 rotates around the central axis of its connection with the lock housing 1, and the extended end 4 of the handle 2 begins to move downward and rotate, pushing the linkage piece 12 at the right end inside the lock housing 1 to start rotating around the central axis of the linkage rod 13. The end in contact with the extended end 4 moves downward, and the end with the driving block 14 begins to rotate upward around the central axis of the linkage rod 13, pushing the dial 6 to rotate around the central axis of the rotating rod 9, so that the end of the dial 6 located inside the through groove 10 begins to rotate downward, pressing down the lock tongue 5, so that the front end of the lock tongue 5 moves into the lock housing 1, the telescopic spring 16 begins to be compressed, and at the same time the torsion spring 15 begins to store energy. When the personnel release the handle 2, the extended end 4 no longer presses down one end of the linkage piece 12. At this time, the torsion spring 15 begins to drive the linkage piece 12 to reset, the driving block 14 begins to rotate upward, and the telescopic spring 16 begins to reset, pushing the lock tongue 5 to extend out of the lock housing 1.

[0030] When the lock tongue 5 of the lock is upward and the personnel need to install the lock tongue 5 downward. As Figures 4 to 7As shown, the personnel first open the interior of the lock shell 1, and then start to remove the positioning bolts on the baffle 19 one by one. After taking them out, the lower baffle 19 can be taken out, and the lock tongue 5 is simultaneously taken out from the middle of the lock shell 1, and then the plane is rotated forward or reversed 180 degrees to make the lock tongue 5 face downward, and then the lock tongue 5 is put back into the middle of the lock shell 1, the through hole 7 on the baffle 19 is aligned with the positioning hole 11 on the lock shell 1, and the positioning bolts are installed back one by one. At this time, the front end of the lock tongue 5 faces downward, the paddle 6 is located on the left side of the baffle 19, and the driving block 14 on the linkage piece 12 located on the left side of the lock shell 1 contacts the outer wall of the paddle 6. When the personnel pulls the handle 2, the extended end 4 of the handle 2 located at the left end inside the lock shell 1 will start to rotate and move downward, pressing the position The linkage piece 12 at the left end inside the lock shell 1 rotates around the central axis of the linkage rod 13, and the driving block 14 of the linkage piece 12 begins to push the paddle 6, so that the paddle 6 is located at one end of the through groove 10 of the lock tongue 5 and rotates upward, pulling the lock tongue 5 downward to move vertically back to the lock shell 1, and the torsion spring 15 outside the linkage rod 13 begins to accumulate force, and the telescopic spring 16 at the bottom end of the lock tongue 5 also begins to compress. When the person loosens the handle 2, the extended end 4 at the left end of the handle 2 is no longer subjected to force to press down the linkage piece 12, and the torsion spring 15 begins to reset, driving the linkage piece 12 to rotate and move upward around the central axis of the linkage rod 13, and the driving block 14 no longer rotates to push the paddle 6, and the telescopic spring 16 begins to reset and push down, and the front end of the lock tongue 5 moves vertically out of the lock shell 1.

[0031] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
