Abstract: A door lock includes a lock latch, a first locking mechanism, and a second locking mechanism. The first locking mechanism and the second locking mechanism can be relatively screwed and tightened and assembled with the lock latch. The second locking mechanism includes an elastic buckle component and a ratchet portion, which can only be screwed and assembled in clockwise direction with the first locking mechanism due to the one-way engaging between the elastic buckle component and the ratchet portion. That is to say, through the design of the elastic buckle component and the ratchet portion of the second locking mechanism to engage with each other, the second locking mechanism can be prevented from being unscrewed relative to the first locking mechanism. This prevents the door lock from loosening due to children playing with it. In other words, the door lock of the present invention has the effect of preventing loosening.

Abstract: A door bolt lock structure contains: a casing, a drive element, a slide plate, and a head. The casing includes a cavity and a locking orifice. The drive element is accommodated in the cavity and includes a lock cylinder and a control lever. The slide plate slidably is received in the drive element and includes a holder, a groove, a free segment, a first locating orifice, and a second locating orifice. The head includes a trench and a threaded orifice, such that the threaded orifice is selectively aligned with the first locating orifice or the second locating orifice of the slide plate, and a second screw element is inserted through the locking orifice of the casing, the first locating orifice or the second locating orifice, and the threaded orifice of the head so as to adjustably move the head with respect to the slide plate.

Abstract: A door lock, assembled in a door sheet, is provided, wherein the door lock has a latch, a first locking mechanism, and a second locking mechanism, wherein the door lock is adapted to be assembled on the door sheet through coupling the first locking mechanism and the second locking mechanism onto the latch. The first locking mechanism and the second locking mechanism have a spiral resilient member screw and abut on a bulge so as to lock the first locking mechanism and the second locking mechanism corresponding to the door sheet. At the same time, an engaging member of the second locking mechanism can both resiliently abut against an upper engaging member and a lower engaging member of the first locking mechanism, so as to limit the lateral movement of the first locking mechanism and the latch, which is not only assembled conveniently. Besides, the engaging and abutting structures among the engaging member, the upper engaging member, and the lower engaging member as well as the spiral resilient member and the bulge are very simple and effective.

Abstract: A lock, adapted for being assembled on a door panel, is provided. The door sheet has an assembling hole and a latch slot connected and communicated with the assembling hole. The lock includes a latch assembly, a first locking mechanism, and a second locking mechanism. The latch assembly is assembled in the latch slot and extended into the assembling hole. The first locking mechanism and the second locking mechanism are assembled in the assembling hole from the two sides thereof respectively to automatically position and affix the latch assembly. Because the latch assembly can be to led to move and positioned in the latch slot and the assembling hole by the first locking mechanism and no screw or other tool are required for fastening in the entire process of the assembling, the present invention is therefore easy and convenient to assemble.

Abstract: A method, system and computer-readable medium for obtaining a temperature profile of a wellbore is disclosed. Raw temperature data are obtained from the wellbore using a distributed temperature sensing system. The raw temperature data includes noise. A numerical decomposition is performed on the raw temperature data within a dynamic window in a measurement space of the raw temperature data to obtain decomposition terms of order of first order and higher. An adaptive filter is applied to the decomposition terms of first order and higher within the dynamic window to reduce noise from the decomposition terms of first order and higher. The filtered decomposition terms of first order and higher are used to obtain a temperature profile of the wellbore.
