Description

Door and window accessory suitable for different model depths Technical Field The invention relates to the technical field of door and window hardware, in particular to a door and window accessory applicable to different types of material depths. Background In the field of door and window manufacturing and installation, accessories such as lock boxes, handle seats and the like are usually required to be fixed in cavities of door and window profiles. At present, a common fixing mode is to directly lock the main part of the accessory on a preset position of the section bar through a screw. However, there are differences in the depth (i.e., the dimension in the front-to-back direction) of the cavities between different manufacturers and different series of door and window profiles. This results in fittings designed for a particular profile which often cannot be directly adapted to profile cavities of other depths. During installation, gaskets may need to be added, sectional materials may need to be cut or accessories may need to be replaced, so that the installation process is complicated, the efficiency is low, and the firmness and the attractiveness of installation may be affected. Therefore, there is a need for a universal door and window fitting structure that can flexibly accommodate different depth profile cavities. Disclosure of Invention The invention aims to provide a door and window accessory suitable for different types of material depths, and aims to solve the problems. In order to achieve the purpose, the invention adopts the following technical scheme that the door and window accessory suitable for different model depths comprises: The fixing base is provided with an opening at the rear side; The movable seat is accommodated in the fixed base in a sliding manner, and can extend backwards through the opening; the depth adjusting mechanism is arranged between the fixed base and the movable base, and can drive the movable base to move along the front-back direction relative to the fixed base so as to adjust the length of the movable base extending backwards along the opening. Further, the fixed base comprises two oppositely arranged first side plates, the movable seat comprises two oppositely arranged second side plates, the second side plates are provided with gourd holes for installing lock cylinders, and the first side plates are provided with avoidance holes corresponding to the gourd holes. Further, the depth adjusting mechanism comprises an adjusting bolt and an adjusting nut in threaded fit with the adjusting bolt, the adjusting bolt is rotatably mounted on the fixed base, and the adjusting nut is fixedly arranged on the movable seat. Further, the number of the adjusting bolts is two, and the adjusting bolts are respectively arranged on two opposite sides of the movable seat along the height direction. Further, a guiding structure for limiting the moving direction of the movable seat is arranged between the movable seat and the fixed base. Further, the guide structure comprises a sliding pin fixedly arranged in the fixed base and a sliding groove arranged on the side surface of the movable seat, and the sliding pin is in sliding fit with the sliding groove. Further, the guide structure comprises a guide groove arranged on the side surface of the fixed base and a guide protrusion arranged on the side surface of the movable seat, and the guide groove is in sliding fit with the guide protrusion. Further, the novel lock comprises a lock tongue assembly, the lock tongue assembly comprises a lock tongue and a lock tongue seat, the front end of the lock tongue is movably connected with the fixed base up and down, the rear end of the lock tongue is movably inserted into the lock tongue seat back and forth, and the lock tongue seat is movably connected with the movable seat up and down. Further, a notch is formed in the front side surface of the fixed base, and the lock tongue is in sliding fit with the notch and extends to the front of the fixed base at least partially. Further, the opposite ends of the fixing base along the height direction are provided with mounting portions, clamping pieces and fixing screws are arranged on the mounting portions, and the fixing screws penetrate through the mounting portions and are connected with the clamping pieces. Compared with the prior art, the structure has the beneficial effects that the length of the extending movable seat can be continuously and steplessly adjusted by arranging the fixed base and the movable seat which can slide relatively and providing the depth adjusting mechanism, when the structure is installed, the front side of the fixed base is propped against the front inner wall of the profile cavity, then the movable seat is driven to extend backwards by the depth adjusting mechanism until the movable seat is propped against the rear inner wall of the profile cavity, and finally the installation part is locked, so that the structure can be perfe
