This utility model discloses a rail mileage measuring device and a rail detector. The rail mileage measuring device includes a base, rollers, a connecting shaft, a coupling, and an encoder. The base has two fixing holes and a positioning part, with the positioning part located between the two fixing holes. The two fixing holes are screwed to the rail detector, and the positioning part abuts against the rail detector. The base also has a through hole penetrating the base, with a connecting shaft installed inside the through hole. The two opposite ends of the connecting shaft protrude out of the through hole and are respectively connected to the rollers and the coupling. The end of the coupling away from the connecting shaft is connected to the encoder. The rollers, connecting shaft, coupling, and encoder are coaxially arranged. The encoder is electrically connected to the rail detector through a wire. The rotation of the rollers directly drives the encoder through the coupling, converting mechanical motion into electrical signals in real time, eliminating the cumulative errors of traditional manual counting or indirect measurement. The rollers rotate more smoothly when in contact with the side of the rail, avoiding slippage or jamming.

According to the door and window gear transmission lock box for rapid installation, a side-screwing screw hole is formed in the side surface of at least one side of the transmission lock box and is matched with a mounting hole and a side-screwing screw in a lock box outer wrapping assembly, and rapid installation and fixation between a door and window profile and the transmission lock box are achieved. According to the design, the installation steps are simplified, the installation efficiency is improved, the stability and reliability of the lock box structure are effectively enhanced, screws can be prevented from being directly exposed on the surface, damage to the appearance of the lock box is avoided, and the overall attractiveness is improved. In addition, due to the matching mode of the side-screwing screw hole and the side-screwing screw, the lock box can be finely adjusted according to actual requirements in the installation process, and accurate positioning and stable operation of doors and windows are guaranteed. And meanwhile, the lock box cover plate body is tightly connected with the transmission lock box, and the wrapping function of the lock box outer wrapping assembly is achieved, so that the overall protection performance of the lock box is further improved, and the service life is prolonged.

This invention provides an adsorption device for hydrogen peroxide oxidation tail gas, comprising an adsorption tank, an inner filter cartridge, an outer filter cartridge, an adsorption chamber, several air inlets, an adsorption resin layer, an inlet pipe, and an outlet pipe; both the inner and outer filter cartridges are located inside the adsorption tank. This invention optimizes the traditional "flat-lay" structure into a "sleeve-type" coaxial double-layer filter cartridge structure, improving the contact efficiency between the tail gas and the resin, preventing the resin from being blown away or worn, extending its service life, and simplifying the filling process. The elimination of quartz sand filler also simplifies the filling process. The system adopts a "five-in-one-out" operating mode, enabling multiple adsorption tanks to operate in rotation. Combined with steam regeneration, nitrogen purging, and spray cooling processes, it achieves efficient resin regeneration and reuse, significantly reducing operating energy consumption and material replacement frequency. The adsorption system operates stably, has a compact structure, and can continuously and efficiently remove aromatic organic pollutants from the oxidation tail gas, balancing operational economy and environmental friendliness.
