The invention discloses a building component of a cross-shaped special-shaped structure and a mounting method thereof. The building component comprises a central supporting mechanism, and the central supporting mechanism comprises a square pipe; and the reinforcing mechanism is fixedly arranged on the surface of the center supporting mechanism in a sleeving mode, the reinforcing mechanism comprises an installation sleeve arranged on the surface of the square pipe in a sleeving mode, fixing plates are fixedly connected to the four corners of the surface of the installation sleeve, welding blocks are fixedly connected to the surfaces of the fixing plates, and traction pieces are fixedly connected to one sides of the welding blocks. The invention aims to solve the technical problems that when an existing cross-shaped building component forms a steel structure column, flexible adjustment is not convenient to carry out according to different building requirements and load conditions, the diameter of the steel structure column is easily too large or too small, and the internal space and bearing requirements of a building are difficult to meet.

This article discloses a door assembly and a vehicle. The door assembly includes a first door body, a second door body, and a guide rail. The first door body is rotatably mounted on the vehicle body, and the second door body is slidably mounted on the vehicle body, with the second door body positioned below the first door body in the height direction. The guide rail includes a front guide rail disposed at the free end of the first door body and a rear guide rail disposed on the vehicle body. The rear guide rail abuts against the front guide rail to form a complete track for the sliding of the second door body. The door assembly features a novel and technologically advanced opening mechanism, and the door provides a tight seal.

This utility model relates to the field of LED lighting technology, specifically to an assembly-type maintenance and replacement device for LED lights, comprising: a lamp holder; a slot formed on the side wall of the lamp holder; a lampshade structure mounted on the lamp holder, the lampshade structure including a lampshade body, the lampshade body being movably mounted on the lower side of the lamp holder, a movable groove formed on the side wall of the lampshade body, a slider provided on the inner wall of the movable groove, and a guide groove formed at the inner edge of the top surface of the lampshade body. This utility model, by forming a guide groove at the inner edge of the top surface of the lampshade body, increases the opening space at the upper end of the lampshade body. When installing the lampshade body, it is not necessary to precisely align the lampshade body with the lamp holder, increasing the installation tolerance of the lampshade body. Furthermore, when the guide groove abuts against the bottom surface of the lamp holder, it guides the lampshade body to cover the outer side of the bottom surface of the lamp holder, achieving convenient installation of the lampshade body at the bottom of the lamp holder and improving the practicality of the device.

The present invention discloses a building component of a cross-shaped structure and an installation method thereof, which comprises a central support mechanism, wherein the central support mechanism comprises a square tube; a reinforcing mechanism, wherein the reinforcing mechanism is fixedly sleeved on the surface of the central support mechanism, wherein the reinforcing mechanism comprises a mounting sleeve sleeved on the surface of the square tube, wherein the four corners of the mounting sleeve surface are fixedly connected with a fixing plate, wherein the surface of the fixing plate is fixedly connected with a welding block, and one side of the welding block is fixedly connected with a pulling piece. The technical problem to be solved by the present invention is that the existing cross-shaped building components are not convenient for flexible adjustment according to different building requirements and load conditions when forming steel structure columns, which easily leads to the diameter of the steel structure columns being too large or too small, making it difficult to meet the internal space and load-bearing requirements of the building.

The first side door and the second side door are oppositely arranged, the end door is provided with a first door leaf hinged to the box body, the air inlet is provided with an air inlet cover, a plurality of air guide strips are arranged on the air inlet cover at intervals, every two adjacent air guide strips form an air inlet channel, sound insulation parts are arranged on the surfaces of the air guide strips, and the first side door is provided with a second door leaf hinged to the box body. The second side door is provided with a third door leaf hinged to the box body. The movable air compressor comprises the case. The container type case for the air compressor and the movable spiral air compressor have the beneficial effects of being simple in structure, good in noise reduction and shock absorption effect and convenient to maintain.

The present invention relates to a die forging tool and a forging method for a large flange at the end of an end shaft with a large shaft diameter ratio. The forging tool comprises an upper jaw body and a lower jaw body. The upper jaw body is provided with a mounting hole whose axis is parallel to the end shaft. The front and rear sides of the upper jaw body are respectively provided with pin holes. A support platform extending outward from the side of the jaw body is provided below the pin hole. The top surface of the support platform is provided with a downwardly concave arc. An arm is passed through the mounting hole. The arm comprises an arm rod extending into the mounting hole and a clamping block fixed to one end of the arm rod. The clamping block is provided with a clamping arc facing the large flange at the end of the shaft and matching the outer diameter of the large flange at the end of the shaft. The tooling of the present invention is simple to manufacture and has a large opening space. It can be extended under a movable crossbeam for rotation operation. It is suitable for clamping forgings with larger diameters and smaller cross-sectional thicknesses. It saves a large number of gasket sets and does not need to manufacture a special rotating platform with holes. It reduces the labor intensity of workers and improves production efficiency, thereby improving economic benefits.
