[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] Please see Figure 1-5 A novel concealed pipe lock includes a connecting plate 1, a first lock body shell 2 mounted on the side wall of the connecting plate 1, a sleeve 3 mounted on the inner wall of the first lock body shell 2, a gasket 4 mounted on the outer wall of the sleeve 3, a second lock shell 5 mounted on the outer wall of the gasket 4, and a bolt 6 mounted on the inner wall of the first lock body shell 2. Both the inner and outer walls of the sleeve 3 are threaded, and the sleeve 3 is threadedly connected to the first lock body shell 2. The sleeve 3 is movably connected to the gasket 4, and the sleeve 3 is threadedly connected to the bolt 6. In use, by installing sleeves 3 of different lengths inside the first lock body shell 2, placing an appropriate number of gaskets 4 according to the door thickness, and then fixing with bolts 6, the installation of the device can be accommodated for different door thicknesses.

[0027] Please see Figure 1-5 A novel concealed pipe lock comprises a lock cylinder 7 mounted on the outer wall of a first lock body shell 2, a lock cylinder cover 8 mounted on the outer wall of the lock cylinder 7, a rotating shaft 9 mounted on the side wall of the lock cylinder cover 8, a rotating rod 10 mounted on the inner wall of the lock cylinder cover 8, a handle 11 mounted on the side wall of the rotating rod 10, a spring 12 mounted on the side wall of the handle 11, and a latch lock 13 mounted on the side of the rotating rod 10 away from the handle 11. The lock cylinder cover 8 and the lock cylinder 7 form a rotating structure via the rotating shaft 9, and the lock cylinder cover 8 is movably connected to the rotating rod 10, locking... The latch 13 forms a rotating structure with the lock cylinder cover 8 via the rotating rod 10, and the lock cylinder cover 8 is engaged with the lock cylinder 7. When using the device, the lock cylinder cover 8 is rotated by the rotating shaft 9, so that the lock cylinder cover 8 closes the opening of the lock cylinder 7. Then, it is pulled outward, and the spring 12 rebounds to insert the latch 13 into the lock cylinder 7. Then, the handle 11 is rotated to fix the lock cylinder cover 8 with the latch 13 and protect the inside of the lock cylinder 7 to prevent external water and debris from entering the inside of the lock cylinder 7.

[0028] Please see Figure 1-5A novel concealed pipe lock is described, wherein a buffer protective sleeve 14 is installed on the outer wall of the lock cylinder 7, and buffer pads 15 are installed on the inner walls of the first lock body shell 2 and the second lock shell 5. Anti-corrosion paint 16 is applied to the outer walls of the first lock body shell 2 and the second lock shell 5. The buffer protective sleeve 14 is fitted onto the lock cylinder 7, and the inner wall of the buffer protective sleeve 14 is tightly fitted to the outer wall of the lock cylinder 7. The inner walls of the first lock body shell 2 and the second lock shell 5 are tightly fitted to the surface of the buffer pads 15, and the first lock body shell 2 and the second lock shell 5 are glued to the anti-corrosion paint 16. When using the device, the buffer protective sleeve 14 fitted onto the lock cylinder 7 effectively protects the lock cylinder 7 from damage when subjected to impact.
