The utility model relates to building decoration technical field, concretely disclose a kind of aluminium alloy door mounting structure, including frame, door leaf and side plate, the frame is connected with wall body, the side plate, door leaf is connected with frame, the frame includes: the main frame portion of being arranged in the corner of wall body, the main frame portion includes vertically arranged first type frame and second type frame, first type frame is provided with first connecting frame in one end away from second type frame, and first type frame is provided with first plug-in frame in one end away from second type frame;Sub-frame portion is arranged in the corner of another wall body, and the sub-frame portion includes third type frame, and the two sides of third type frame are provided with second connecting frame and third connecting frame respectively, and second connecting frame side is provided with second plug-in frame.The utility model is convenient for the quick installation connection of frame, wall surface, door leaf and side plate, and the accuracy of connection is improved simultaneously.

The utility model relates to photovoltaic module technical field discloses a kind of photovoltaic module gapless mounting structure, including first photovoltaic board: one side of the first photovoltaic board is equipped with second photovoltaic board, the front end of the first photovoltaic board and second photovoltaic board with one side is fixedly connected with two fixed blocks, the rear end of the first photovoltaic board and second photovoltaic board with other side is fixedly connected with two mounting plates, the bottom end of the first photovoltaic board and second photovoltaic board is equipped with contact pad, the surface of the mounting plate is equipped with two clamping grooves. The photovoltaic module gapless mounting structure, through the setting of the convenient gapless installation between first photovoltaic board and second photovoltaic board, when staff needs to install, only needs to be aligned and clamped, first photovoltaic board and second photovoltaic board can be realized quickly gapless installation connection, and then effectively improve installation efficiency, reduce installation difficulty.

This utility model relates to the field of casting mold technology and discloses a pulverized coal injection pipe casting refractory construction mold, including a lower mold. A positioning strip is provided on the upper side of the lower mold. An upper mold, which limits the positioning strip, is fixedly connected to the upper surface of the lower mold. An injection port is provided on the upper surface of the upper mold. A positioning component is installed on one side of the outer wall of the lower mold. The positioning component includes a hinge seat, one side of which is fixedly connected to one side of the outer wall of the lower mold. A clamping plate is rotatably connected to one side of the outer wall of the hinge seat. In this utility model, by placing the upper mold on the lower mold, positioning it with the positioning strip, and pressing down the L-shaped limiting rod, the rod drives the limiting shaft to slide in the inclined groove, thereby driving the clamping plate to rotate, ultimately causing the clamping plate to abut against and fix the upper mold. This design achieves a fast and automatic mold closing and locking effect, solving the problem of inconvenient installation of traditional molds and improving practicality.
