The embodiment of the application provides a device for detecting tooth root of goods of unmanned forklift, comprising an unmanned forklift, characterized in that: the bottom of the unmanned forklift is provided with a fork, and a tooth root sensing assembly is arranged at the root of the fork; the tooth root sensing assembly is embedded in the internal groove area of the fork, and the tooth root sensing assembly is lifted synchronously with the fork; the tooth root sensing assembly comprises a sensing plate, a proximity switch, a fixing support, a sensing bolt, a rotating shaft, a torsional spring and a bolt. The technical problem solved by the application is to provide a device for detecting tooth root of goods of unmanned forklift, which combines mechanical structure and inductive proximity switch to improve the stability and reliability of goods detection, enhance the adaptability to low-temperature environment, and reduce maintenance cost.

The invention discloses a photovoltaic module frame anti-seepage connection structure, and relates to the technical field of photovoltaic module frames, the photovoltaic module frame anti-seepage connection structure comprises a water tank and an anti-seepage unit, the water tank is characterized in that the two sides of the top surface of the water tank are attached to the bottom surfaces of two placement racks correspondingly attached to the inner side surfaces, the bottom ends of the two placement racks are fixedly provided with frames, and the frames are fixed to the bottom surfaces of the two placement racks; a fixing unit is arranged on the top surface of the frame; the water seepage prevention unit comprises a fixing screw rod, a support, a mounting bolt, a pressing and fixing frame, a fixing base, a spring groove, a pressing and fixing spring and a water seepage prevention pressing plate, according to the photovoltaic module frame water seepage prevention connecting structure, the water tank can be fixed to the top face of the photovoltaic support through cooperation of the frame and the clamping and fixing plate, and the fixing screw rod is rotated to enable the pressing and fixing frame to press and fix the photovoltaic module frame; the pressing and fixing spring contracts so that the anti-seepage water pressing plate can be pressed on the top face of the photovoltaic module frame, and the problem that water seepage occurs in connection between the photovoltaic module frames is solved in cooperation with the anti-seepage water pad.

The utility model relates to the technical field of lens protection, and discloses a lens module and an optical device, the lens module comprises a lens cover, a lens seat and a linkage member, one end of the lens seat is provided with a lens, one end of the linkage member is rotatably connected with the lens cover, the other end of the linkage member is rotatably connected with the lens seat, and when the lens cover rotates towards a second rotation direction relative to the linkage member, the lens cover rotates towards the second rotation direction. The lens cover can rotate to the outer side of the lens when the lens cover rotates in the first rotation direction relative to the lens base and the linkage piece rotates in the second rotation direction relative to the lens base, and the lens cover can rotate to the peripheral side of the lens base when the lens cover rotates in the first rotation direction relative to the lens base and the linkage piece rotates in the first rotation direction relative to the lens base; the end, close to the lens cover, of the linkage piece can extend towards the outer side of the lens base, the distance between the lens cover and the outer surface of the lens base is increased, a certain gap can be kept between the lens cover and the outer surface of the lens base all the time, direct contact abrasion of the lens cover and a functional structure on the lens base is avoided, the unfolding angle of the lens cover is increased, and the view of the lens is prevented from being shielded.

The utility model discloses an electric collapsible signal lamp mast which comprises a base and a mast body which are arranged on a ship deck, a movable column extending to the outside is arranged in the base, the mast body is arranged at the top end of the movable column, a U-shaped connecting frame is arranged at the bottom end of the movable column, the U-shaped connecting frame is connected with the base through a connecting shaft, and the mast body is connected with the base through the connecting shaft. An adjusting assembly connected with the movable column is arranged in the base. The device has the beneficial effects that the movable column rotates in the stroke hole space of the base, and the mast rotates along with the movable column, so that the movable column can be put down and lifted up; the adjusting assembly operates to drive the movable column to rotate, the mast can be easily lifted, and the labor-saving effect is achieved. When the mast is put down, the bracket can play a role in supporting the mast to prevent the mast from being in direct contact with the deck to be abraded, meanwhile, the falling mast can be fixed more conveniently, and the situation that the mast deforms due to the fact that the mast swings under the action of external force is prevented.
