The invention provides a combined spliced door frame. A vertical pillar and a beam of the combined spliced door frame are each provided with steps corresponding to a door. The vertical pillar and the beam are each integrally formed through medal plates. The vertical pillar end of the vertical pillar and the beam end of the beam are spliced and combined, an inserting groove is formed in the low step of the vertical pillar end, and the high step of the vertical pillar end inwards retracts to form a first platform. A first inserting plate is arranged on the first platform in an extending mode, an inserting hole is formed in the high step of the beam end and matched with the first inserting plate in a corresponding mode, and the inserting hole is provided with an axial hole width for movement of the first inserting plate. The high step of the beam end is matched with the first platform in a corresponding mode, the low step of the beam end inwards retracts to form a second platform, and a second inserting plate is arranged on the second platform in an extending mode and matched with an inserting groove in a corresponding mode, and the second platform is matched with the low step of the vertical pillar end in a corresponding mode. Under the uncombined state, the vertical pillar and the beam are separated, conveying and moving are convenient, the more door frames are contained in the same space, the space is effectively utilized, and cost for conveying, storing and the like is reduced; and during crossed assembly combination, assembly is convenient, the structure is stable, and extra connecting pieces are not needed.

The invention discloses an injection molded raft shell, which relates to the field of raft shells. Aiming at the problems that the existing life raft shells are inconvenient to be assembled and connected at one side of the ship in an efficient and arbitrary manner, and at the same time it is inconvenient to store them stably, the following scheme is proposed , which includes an upper raft shell and a lower raft shell. A connecting plate is arranged on the rear side of the upper and lower raft shells close to one end face, and the upper and lower sides of the connecting plate are respectively connected with the upper raft shell, The lower raft shell is rotatably connected, the outer sides of the upper raft shell and the lower raft shell are fixedly fitted with arc-shaped plates in an array, and the adjacent sides of the two adjacent arc-shaped plates are provided with arc-shaped slide rails. The inner wall of each arc-shaped slide rail is provided with a plurality of limiting square holes in an array, and an arc-shaped slide plate is arranged between two adjacent arc-shaped slide rails. The device can be assembled and assembled conveniently, which is convenient for installation on one side of the ship and convenient for storage.

The invention discloses a fastening component which comprises a first buckle piece, a second buckle piece and an elastic device. The first buckle piece edge and the second buckle piece edge are respectively provided with a first notch and a second notch which are opposite to each other. The elastic device operates on at least one of the first buckle piece and the second buckle piece so that the first notch and the second notch close up to form a through hole. If an object that is larger than the through hole passes through the through hole, the object overcomes the elastic force of the elastic device to enable the first buckle piece and the second buckle piece to move in the opposite direction. The fastening component provided by the invention has the advantage that a fastened object can be more simply and conveniently assembled with the fastening component and is simply and conveniently pulled out. Due to two symmetrically arranged buckle pieces, pressure springs or spring pieces, the fastening component can be applied in the case of assembling a hanging sliding door.

The invention discloses a method for controlling the verticality of the painting of the base layer of the exterior wall of a high-rise building, and belongs to the field of painting of the base layer of the exterior wall of a building. On the outer wall A of the high-rise building, at a distance of 100mm from the outer corner of the outer wall, use an infrared plummet and an ink fountain to pop up a vertical ink line; at the upper and lower ends of the outer wall A, fix a positioning plate with expansion bolts, and the upper and lower positioning plates The outer side is tightened with a steel wire, the distance between the steel wire and the wall B is the base painting thickness required by the drawing design, and the steel wire is parallel to the vertical ink line; when painting the outer wall B, first press a thickness control board on the side of the outer wall A, The thickness control plate is parallel to the steel wire; first, the wall on the side of the outer wall B that is away from the steel wire, the width of which is not less than 500mm, is scraped and calendered, and then the entire outer wall B is painted; after the outer wall B is painted After the completion, repeat the above steps to paint the exterior wall surface A. In turn, it ensures the construction and perception quality of the exterior wall decoration of high-rise buildings, and finally achieves the best three-dimensional effect of high-quality projects.

The invention discloses a soft-packed battery module, which includes a soft-packed battery and a battery frame. The battery frame is sheathed around the soft-packed battery. The fixing glue, the invention also discloses the manufacturing method of the soft-pack battery module. In the present invention, the soft-packed battery cell and the regular-shaped cell frame are integrated into a soft-packed battery cell module, which has a uniform size endowed by the cell frame, and the soft-packed battery cell can be protected and strengthened by the cell frame and fixing glue, so that It has become a unit that is easy to assemble, store and transport, has higher strength and is more practical, which effectively solves the damage of the battery cells caused by the production and transportation of the soft-packed batteries, and greatly improves the pass rate and yield of the batteries. Moreover, it is convenient to realize the fully automated production of power batteries with pouch cells, which can greatly improve production efficiency.

The invention discloses a press type screwdriver head storage seat which consists of a seat body, a blocking buckle, a spring and a gland unit, wherein the gland unit comprises a gland, a gland extension rod and a screwdriver head storage base; the gland extension rod is provided with a locating column; the blocking buckle is arranged on the seat body; the gland unit is connected with the seat body in a sliding way, and the gland and an opening end of the seat body are closed with each other, or a pick-up gap is reserved between the gland and the opening end of the seat body; the locating column is connected with the blocking buckle in a blocking way, or is separated from the blocking buckle; the spring is arranged between the bottom of the screwdriver head storage base and a closed end of the seat body. After the press type screwdriver head storage seat is applied, storage and pick-up are conveniently carried out since the screwdriver head storage seat is in a press type; in the pick-up process, scattering is not easily caused; the press type screwdriver head storage seat is small in volume and convenient to carry; spacing grids are adopted, so that the storage space is divided into a plurality of independent storage spaces, and screwdriver heads are stored in a way of classification; the storage seat adopts a structure of splicing the seat body and the base, and the base is connected with the seat body by screw threads, so that assembly is convenient, and production is fast and convenient.
