And the installation efficiency of the connecting piece is influenced.

The utility model discloses a kind of semi-trailer unloading devices, belong to semi-trailer field, including semi-trailer, the top of semi-trailer is fixedly connected with vertical plate, the top of semi-trailer is rotatably connected with several conveying rollers;The top of semi-trailer is fixedly connected with two protective plates, the top inside of protective plate is fixedly connected with three electric push rods, the bottom output rod of electric push rod is fixedly connected with driving frame, the inside sliding connection of driving frame has two round rods;Through the cooperation of above each device, by setting object carrier plate, it is placed to predetermined position, by the cooperation of insert block and clamping groove to limit object carrier plate, not only improve the stability of object carrier plate in the process of transportation, also provide guarantee for the stable transportation of goods, the two protective plates of the top of semi-trailer can also play certain limiting effect to goods, reduce the collapse accident caused by goods due to inclination, greatly reduce the wobble of object carrier plate in the process of transportation.

The invention provides an indoor intelligent security camera for smart home and a use method, which relates to the field of cameras and comprises a moving mechanism: the moving mechanism is an intelligent security camera body, which is a spherical structure; a cleaning piece is mounted on the bottom of a support piece on the cleaning mechanism; a gear on a transmission piece meshes with a wedge-shaped tooth on a contact piece; and a lower synchronous wheel is mounted on both sides of the top of the cleaning piece: the moving piece is driven to move back and forth by the top piece, so that when the main body moves to the cleaning piece, the wedge-shaped tooth at the bottom of the contact piece meshes with the gear on the transmission piece, so that the transmission piece drives the synchronous wheel to rotate inside a circular hole on the support piece, and through the effect of belt transmission on the synchronous wheel, the synchronous wheel drives the cleaning piece to flip left and right, so that the cleaning piece cleans dust on the main body, thereby solving the problem that the existing intelligent security camera cannot clean dust on the camera when the camera moves during use.

The utility model relates to the technical field of wooden furniture, and discloses a wooden furniture mounting structure which comprises a wood board, and a mounting mechanism is mounted on one side of the wood board. According to the wooden furniture mounting structure, a wood plate is held to move, the wood plate is inserted into the mounting frame, after the wood plate enters the mounting frame, the surface of the wood plate is in contact with an anti-skid pad, so that the movement of the wood plate is limited, and then a screw rod is inserted into the mounting frame and the wood plate, so that the movement of the wood plate is limited; and finally, a nut is held to rotate, the nut is arranged on the surface of the screw in a sleeving mode, the splicing position of the wood board can be fixed, and the problems that fixing is conducted simply through a steel nail, after a wooden home is used for a certain time, the steel nail is prone to shifting in the wood board, a groove is dug in the wood board in the shifting process of the steel nail, and the wood board cannot be damaged are solved. And when the wooden home furnishing is stressed, the steel nails can move in the grooves, so that the problem that the stability of the wooden home furnishing is reduced is solved.

The utility model discloses a cylindrical surface support which comprises an upper seat plate, a plane stainless steel sliding plate, a lower seat plate, a middle seat plate, a plane sliding plate, a cylindrical surface stainless steel sliding plate and a cylindrical surface sliding plate, and the plane stainless steel sliding plate is fixed on the lower surface of the upper seat plate; the upper surface of the lower seat plate is a concave cylindrical surface; the lower surface of the middle seat plate is a convex cylindrical surface matched with the concave cylindrical surface; the plane sliding plate is fixed to the upper surface of the middle base plate and abuts against the plane stainless steel sliding plate to form a plane sliding friction pair. The cylindrical surface stainless steel sliding plate is fixed on the convex cylindrical surface; the cylindrical sliding plate is fixed to the concave cylindrical surface and abuts against the cylindrical stainless steel sliding plate to form a rotating friction pair. The cylindrical surface support with the overturn-preventing and beam-falling-preventing functions adopts a plane and rotating friction pair structure, can flexibly rotate in the radial direction of the cylindrical surface, realizes the rotation of a bridge in the longitudinal direction of the bridge, cannot rotate in the axial direction of the cylindrical surface, prevents a beam body from rotating in the transverse direction of the bridge to cause an overturn beam-falling accident, and improves the safety of the bridge. The technical problem of design of different base plate type height-adjusting supports is solved.
