This utility model discloses a mold for manufacturing composite floor slabs, relating to the technical field of building component production equipment. It includes a base with legs fixed to its upper end. Support plates are connected to the upper ends of the four legs. A forming hole is provided in the middle of the support plate, and a demolding component is provided at the forming hole. A side mold structure is provided above the forming hole. The side mold structure includes first side plates positioned at opposite ends of the forming hole and located above it. A second side plate is positioned between the ends of the two first side plates. Each end of the first side plate has a locking slot, and the ends of the second side plate are respectively engaged inside the two locking slots. In this utility model, the positioning pin cooperates with the positioning hole, and the locking block engages with the locking groove, improving the positioning accuracy and stability of the side mold. The electromagnetic vibrator can compact the concrete, eliminate air bubbles, and facilitate demolding. The hydraulic push rod drives the support plate for convenient demolding. The positioning groove prevents stones from supporting the reinforcing mesh, ensuring the quality of the composite floor slab pouring.

The application discloses a foundation pit slope protection and reinforcement device for civil engineering, which comprises at least one slope protection plate, at least one fixed plate, at least one movable plate, two reverse pushing mechanisms, at least one one-way mechanism, an X-shaped connecting rod frame, at least one connecting rod, a first long rod, four butt joints, a second long rod and at least one sliding block. The reverse pushing mechanism, the fixed plate and the movable plate are arranged to effectively support the collapse point in time from the initial small-range collapse according to the characteristics of the foundation pit collapse, the timely support of the collapse point can effectively prevent the collapse of the whole surface of the foundation pit, and the large number of casualties and property losses can be avoided. Furthermore, the first long rod, the second long rod and all the connecting rods are arranged to link all the one-way mechanisms to extend and preventively support the whole pit wall, maintain the shape of the foundation pit, disperse the support force of the single reverse pushing mechanism or the one-way mechanism and increase the overall bearing capacity of the pit wall.

The utility model relates to the technical field of compressor screw machining, and provides a clamping device for compressor screw machining to solve the problems that an existing clamping conveying device is difficult to adapt to a long screw and cannot stably support the long screw, so that the grinding precision and efficiency are low. The device is composed of a bottom frame, a movable mechanism and a fastening mechanism. The movable mechanism enables the mounting shell to flexibly move to be matched with the length of the screw rod through fixing blocks, sliding rods and sliding sleeves which are fixed to the two sides of the top of the bottom frame. A semicircular mounting seat of the fastening mechanism is arranged in a mounting shell, a movable rod is pushed by a spring, so that the semicircular mounting seat is attached to a screw rod, and rollers on the inner side of the semicircular mounting seat can support the screw rod and reduce friction force during grinding. In addition, the two semicircular mounting bases are symmetrically arranged, the inner side rolling wheels make contact with the screw rod in an all-dimensional mode, and even supporting during grinding is guaranteed. Practical application verifies that the clamping device effectively improves the stability, precision and efficiency of screw grinding, and powerful support is provided for high-quality development of the compressor screw machining industry.

This application relates to the field of armored reels for steel strip coils, and more particularly to an armored reel adaptable to steel strip coils with multiple inner diameters. It includes a fixed base and an adjusting assembly. The fixed base has multiple guide grooves on its surface, arranged in a circular array around the central axis of the fixed base and extending radially along the base. The adjusting assembly includes an inner diameter adjusting ring coaxial with the fixed base and multiple sliders. Each slider engages with a guide groove. The outer circumferential surface of the inner diameter adjusting ring is conical and movable in a direction perpendicular to the fixed base. The sliders abut against the outer circumferential surface of the inner diameter adjusting ring. When the inner diameter adjusting ring moves, the sliders slide along the guide grooves. This application, through the cooperation of the inner diameter adjusting ring and the sliders, achieves effective support for steel strip coils with different inner diameters, featuring flexible adjustment and wide applicability, significantly improving the versatility and stability of the armored reel.

The utility model discloses a refrigerator relates to refrigerator technical field, wherein, the refrigerator includes box and water receiving structure, and the box is equipped with the cavity of compressor installation, and the lower extreme of cavity is equipped with the installation mouth, and the rear side end of box has the bottom end part, and the water receiving structure includes the mounting piece and water receiving box, and the mounting piece is located in the installation mouth, and the water receiving box sets up the upper end of mounting piece, and the mounting piece forms the support part, and the support part projects downward setting all to bottom end part, and the support part is at the front side of bottom end part, and the part between mounting piece and bottom end part of water receiving box projects downward to form the box body bottom, wherein, the support part and bottom end part form the first ground contact inclined plane, and the box body bottom is no less than the first ground contact inclined plane, so that the box body bottom projects downward on the first ground contact inclined plane when the refrigerator rotates, avoids the water receiving box to support the box, thereby solve the problem that the water receiving box is easily damaged because of the load when the refrigerator rotates.
