The invention discloses an assembling integrated support hanger and connecting pieces thereof. The assembling integrated support hanger structurally comprises a base, an upright column, a crossbeam, a first connecting piece and a second connecting piece; the upright column is made of C-type steel, and the crossbeam is made of H-type steel; connecting holes are respectively formed in the base, the two ends of the upright column and the two ends of the crossbeam. Aiming at the special structure of the H-type beam, the first connecting piece is shaped like a T-shaped structure when being connected with the upright column and the crossbeam, and aiming at the stability of a central upright column, the second connecting piece is in a trapezoidal structure when being connected with the upright column and the crossbeam. The assembling integrated support hanger provided by the invention adopts special connecting pieces, namely T-shaped and trapezoidal connecting pieces, aiming at different stress requirements of different structures, so that the stability degree of the support hanger is improved while the mounting is facilitated as well, the stress is reliable, and the construction is safe.

The invention discloses a detachable supporting hanging frame which structurally comprises a vertical column, a cross beam, a first connector, a second connector and a supporting connector, wherein the vertical column and the cross beam are both made of C-shaped steel; connecting holes are formed in the two ends of the vertical column and the cross beam; a connecting hole is formed in the supporting connector; the first connector comprises a first component; the cross section of the first connector is T-shaped; the first component comprises a cross edge and a bent edge; the second connector comprises a first fixed edge, a second fixed edge and a third fixed edge; the second connector has an integrated structure; the first and second connectors are used for meeting different structure and stress demands; the mounting is convenient while the stable degree of the supporting hanging frame is increased; the force bearing is reliable; the construction is safe.

The invention discloses a plug structure for bedding. The plug structure comprises a column 1 and a cross bar connected with the column, and the column and the cross bar are connected through a connector 8 which comprises a cylinder 21 and a clamped hook body 22, wherein the clamped hook body comprises a hook-shaped part hooked at the column and a straight-edge part clamped at one side of the column; a cylinder port at the other side of the cylinder is formed with an internally retracted outer edge; and the cross bar is connected at the outer edge. The invention further provides basic forms of single-layer beds or bunk beds and apartment beds based on the above connecting structure. The bedding provided by the invention is beautiful, simple, firm, durable, green, and environmentally friendly. By using a stamping process, a welding process is omitted and production cost is reduced; and by using a component connecting form such as inserting and combining, size is reduced and transportation and installation are facilitated.

The invention provides a permanent magnetic submersible linear motor and a manufacturing method thereof. The permanent magnetic submersible linear motor comprises a mover, a stator and a casing which are sequentially arranged from inside to outside, and resin filling materials are embedded into a gap between the stator and the mover and a gap between the stator and the casing. According to the permanent magnetic submersible linear motor, the gap between the stator and the mover and the gap between the stator and the casing are embedded through the resin filling materials, fully mixing and stirring the filling materials and then embedding the filling materials into the motor stator with an embedding tire are only required in an embedding process, welding during connecting a stainless steel cylinder with a stator core can be avoided, improving safety and quality reliability of the motor is facilitated, moreover, the embedded materials after curing exist in a solid mode, so the motor needs no quite high sealingness, processing precision and dimension requirements of each part of the motor are relatively loose, dimension in the embedding process depends on the embedding tire, and precision is higher compared with the stainless steel cylinder.

The invention provides a circuit board interconnecting device which comprises a signal wire, wherein the signal wire is connected with circuit board modules on different printed circuit boards, a shielding device used for signal reflux is arranged adjacent to the signal wire, and the shielding device is crimped on the circuit module on the printed circuit board through a separating rib. Accordingto the technical scheme, the shielding devices crimped on the circuit boards on different printed circuit boards are directly connected with the separating ribs on the first circuit module and the second circuit module, so the embodiment of the invention realizes the interconnection of the signal reflux, avoids the welding procedure, improves the consistency of the assembly, and reduces the cost.

The invention discloses a double-decker bed based on a plug-in type guardrail. The double-decker bed comprises a vertical post (1) as well as an upper and a lower layer bed surrounded by beams, wherein the upper layer bed is provided with a ladder stand (3); one outer side in the length direction of the upper layer bed is provided with an upper layer bed guardrail; the upper layer bed guardrail comprises a vertical rod (12) and an outer handrail (4); the outer handrail comprises a horizontal straight rod part and an arc-shaped connection rod part; the external end of the horizontal straight rod part is connected to the vertical post (1) by a connecting piece (8); and the arc-shaped connection rod part is connected to the lower beam (2) by an intermediate unit (11). The bed disclosed by the invention has the following characteristics of beauty, simplicity, fastness, endurance and environment friendliness. With the adoption of a stamping technique, the welding process is omitted, so that the production cost is reduced; and with the adoption of an insertion and combination part connection mode, the volume is reduced, and the bed is convenient to transport and mount.

The invention discloses a preparation process and a product of the upper cover of a liquefied petroleum gas bottle. The preparation process of the upper cover of the liquefied petroleum gas bottle includes A, blank pretreatment, B, blank extrusion molding and C, cover body rough blank trimming treatment. The upper cover of the liquefied petroleum gas cylinder includes a cover body and a valve seat, the cover body and the valve seat are made by extrusion, the cover body and the valve seat are integrally formed, and a through hole is provided in the center of the valve seat Threads are provided on the through holes. In the present invention, the valve seat and the upper cover are arranged in an integrated structure, which avoids the welding process of the traditional gas cylinder, reduces the number and length of the welding seams of the whole gas cylinder, and improves the use safety of the gas cylinder; , because there is no relative sliding between the metal material and the inner wall of the extrusion cylinder, the metal flow is uniform during the extrusion process. Compared with the traditional stamping method, the parts prepared by the traditional stamping method have higher dimensional accuracy and a tighter structure; compared with the existing technology, the manufacturing process is reduced, and the production is improved. Improve processing efficiency and reduce production costs.
