Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Embodiment 1: As Figure 1 and Figure 2 shown, a pressing rod type flat lock includes a first fixed seat 1 and a second fixed seat 2 arranged oppositely. The outer surface of the first fixed seat 1 is provided with a pressing rod mechanism 3, the inside of the second fixed seat 2 is provided with an adjusting mechanism 4, and the outer surface of the adjusting mechanism 4 is provided with a lock sleeve 5 that cooperates with the pressing rod mechanism 3.

[0022] The adjusting mechanism 4 includes a mounting block 41 placed inside the second fixed seat 2. T-shaped grooves 42 are opened at the top and one side of the mounting block 41. A T-shaped block 43 is slidably connected inside the T-shaped groove 42. One end of the T-shaped block 43 is fixedly connected to a threaded sleeve 44. Adjusting screws 45 that are threadedly connected to the inside of the threaded sleeve 44 penetrate and are rotatably connected to both sides of the outer surface of the second fixed seat 2. Knobs 46 are rotatably embedded in both sides of the outer surface of the second fixed seat 2, and one end of the knob 46 is fixedly connected to one end of the adjusting screw 45.

[0023] Through the above technical solution, when in use, rotate the corresponding knob 46 to drive the adjusting screw 45 to rotate. Through the thread, the threaded sleeve 44 and the T-shaped block 43 can be driven to move, and then the mounting block 41 can be driven to move, and the position of the lock sleeve 5 can be adjusted, so as to facilitate cooperation with the locking tongue 35, thus solving the problem that it is inconvenient to adjust the existing flat lock after installation.

[0024] The outer surface of the lock sleeve 5 is provided with a locking screw 6 penetrating through it. One end of the locking screw 6 is threadedly connected to the inside of the mounting block 41. A plurality of positioning rods 7 are fixedly connected in sequence on the outer surface of the lock sleeve 5, and a plurality of positioning holes that cooperate with the positioning rods 7 are opened on the outer surface of the mounting block 41.

[0025] Through the above technical solution, the lock sleeve 5 can be easily installed on the mounting block 41 by means of the locking screw 6. The cooperation between the positioning rod 7 and the positioning hole can limit the position of the lock sleeve 5 to prevent sliding.

[0026] The pressing rod mechanism 3 includes two fixed blocks 31 symmetrically and fixedly connected to one side of the outer surface of the first fixed seat 1. A handle 32 is rotatably connected through the two fixed blocks 31. One end of the handle 32 is fixedly connected to a push block 33. A U-shaped frame 34 is fixedly connected to the outer surface of the first fixed seat 1. A lock tongue 35 that cooperates with the lock sleeve 5 is slidably connected inside the U-shaped frame 34. A connecting plate 36 is fixedly connected to the outer surface of the first fixed seat 1. A spring 37 is fixedly connected between one end of the connecting plate 36 and the lock tongue 35. Mounting holes are provided around the outer surfaces of the first fixed seat 1 and the second fixed seat 2.

[0027] Through the above technical solution, rotating the handle 32 can drive the push block 33 to move in an arc, thereby pushing the lock tongue 35 so that one end of the lock tongue 35 enters the inside of the lock sleeve 5 to achieve the locking operation. When the handle 32 is reset, the spring 37 will automatically drive the lock tongue 35 to reset to achieve the unlocking operation.

[0028] Working principle: During installation, the first fixed seat 1 and the second fixed seat 2 are installed at corresponding positions through the respective mounting holes. During use, rotating the corresponding knob 46 drives the adjusting screw 45 to rotate. Through the thread, the threaded sleeve 44 and the T-shaped block 43 can be driven to move, and then the mounting block 41 can be driven to move, and the position of the lock sleeve 5 can be adjusted, so as to facilitate the cooperation with the lock tongue 35, thereby solving the problem that it is inconvenient to adjust the existing flat lock after installation.

[0029] Rotating the handle 32 can drive the push block 33 to move in an arc, thereby pushing the lock tongue 35 so that one end of the lock tongue 35 enters the inside of the lock sleeve 5 to achieve the locking operation. When the handle 32 is reset, the spring 37 will automatically drive the lock tongue 35 to reset to achieve the unlocking operation
