This application relates to a spacing adjustment device, a cabinet, and a refrigerator, specifically in the field of refrigerator technology, and aims to provide a device for facilitating the adjustment of the spacing between the door and the cabinet when closed. The spacing adjustment device includes a housing, a support assembly, and an adjustment assembly. The housing has an adjustment cavity, and a first insertion hole and a second insertion hole communicating with the adjustment cavity. A portion of the support assembly is located within the adjustment cavity, and another portion of the support assembly extends out of the adjustment cavity via the first insertion hole. A portion of the adjustment assembly is inserted into the second insertion hole, and a portion of the adjustment assembly is located within the adjustment cavity. The adjustment assembly is configured to have a switchable first state and a second state. When the adjustment assembly is in the first state, the portion of the adjustment assembly located in the adjustment cavity is drively connected to the support assembly to adjust the insertion depth of the support assembly within the first insertion hole. When the adjustment assembly is in the second state, it prevents the adjustment assembly from driving the support assembly to adjust the insertion depth within the first insertion hole.

The utility model relates to the technical field of building construction, and discloses an internal corner template. The internal corner template comprises a template main body with a right triangle-shaped cross section, wherein the template main body comprises a side inclined surface and two side right-angle surfaces; the internal corner formwork further comprises a butt joint piece, a connecting assembly and a driving assembly, and the butt joint piece is movably arranged on the side inclined face in the extending direction of the side inclined face and can be connected with the plane formwork. The connecting assembly comprises a first connecting piece and a second connecting piece, the first connecting piece penetrates through the formwork body in the vertical direction, the position of the first connecting piece in the vertical direction is adjustable, one end of the second connecting piece is hinged to the first connecting piece, and the other end of the second connecting piece is hinged to the butt joint piece; the driving assembly is detachably arranged on the formwork body, and the driving assembly is connected with the first connecting piece and used for driving the first connecting piece to move vertically. By using the internal corner template, the overall stability of a template system after the plane template and the internal corner template are closed can be ensured, the difficulty of mold closing operation is reduced, and the mold closing speed is increased.

The air blowing mechanism of this application includes: a base, a first air nozzle disposed on the base, and a second air nozzle disposed on the base; the base has a gas outlet, and the gas outlet has a first reflective wall and a second reflective wall on both sides; the first air nozzle faces the second reflective wall, and the second air nozzle faces the first reflective wall, so as to form a vortex between the first reflective wall and the second reflective wall.

The application discloses a sewing machine cloth feeding flatness adjusting system and method and a sewing machine. The adjusting system comprises a first visual sensor, a second visual sensor, a third visual sensor, a sewing machine control system, a track control module, a time sequence control module, a stitch control module, a tension control module and a cloth dragging wheel control module. The first visual sensor is arranged above a thread storage groove of a presser foot and avoids a needle. The second visual sensor is arranged above a left side or a right side of the presser foot. The third visual sensor is arranged above a front side of the presser foot. The first visual sensor, the second visual sensor and the third visual sensor are in communication connection with a signal input end of the sewing machine control system. Signal output ends of the sewing machine control system are in communication connection with the track control module, the time sequence control module, the stitch control module, the tension control module and the cloth dragging wheel control module. The application can adjust the cloth feeding flatness of the sewing machine.
