A small cake tea press forming mold is used in cooperation with an oil press (48) and comprises an upper mold and a lower mold. The upper mold comprises an upper bearing board (1), a positioning board (25), guide columns (5) and a plurality of upper column heads (7); the lower mold comprises a frame, a mold cavity board (4), a connection board (39), a movable board (8), a jack column (11), a lower mold support column (14), two air cylinders I (12), two air cylinders II (13), two air cylinders III (15), two connection blocks (22), two small supports (41), two platens (47) and two support blocks (3); the mold cavity board (4) is provided with mold holes (40) corresponding to the upper column heads (7); the movable board (8) is provided with lower column heads (10) corresponding to the mold holes (40). During operation, firstly, the oil press (48) is started, then steamed tea base raw materials are put into the mold holes (40), and then the press is performed and the pressured is maintained. The labor intensity is low and the production efficiency is high.

The invention relates to a set of large diameter rocket thrust chamber with discharging regenerative cooling partition plates. There are ten kinds such as a liquid oxygen kerosene large or oversize orgiant thrust chamber, a hydrogen oxygen large or oversize thrust chamber, a hydrogen peroxide large or oversize or giant thrust chamber and a hydrogen-rich hydrogen oxygen large or oversize thrust chamber. The regenerative cooling partition plates with fine and long axial holes and with or without end heads in a 13(10) area, a 29(22) area and a 45(34) area are provided, and thus high frequency unstable combustion can be effectively inhibited. An inner cooling improving mode of annular gaps is further provided, so that a liquid film or a gas film is attached to the wall more evenly. A reinforced double-conical-shell head additionally provided with a third bearing connecting piece and a fourth bearing connecting piece is arranged. Axial holes used for gas nozzles and small diameter holes used for liquid nozzles form a straight-flow type injector. The thrust chamber is simple in structure and good in generality, and the number of parts is reduced greatly. The technical difficulty is low,the lead time can be shortened, and the cost is reduced. The hydrogen peroxide thrust chamber and the hydrogen oxygen thrust chamber can be reused for 25-200 times and 2-25 times correspondingly. Theset of large diameter rocket thrust chamber is suitable for manned lunar-landing Mars-landing rocket engines and the like.

The invention discloses a building joint of a modular house combining and splicing structure. The building joint comprises a corner element and a connecting piece connected with the corner element. The corner element comprises a square tube column and a partition board arranged in the square tube column and dividing the interior of the square tube column into multiple square cells. A plurality of bolt holes are formed in the four faces of the square tube column and the partition board respectively. The connecting piece comprises a fixing plate and conical vertical tubes arranged on the fixing plate and capable of being inserted into the square cells in the square tube column to be fixed, and the shape and the size of the fixing plate are same with those of the bottom of the square tube column. The four conical vertical tubes on the fixing plate are distributed on the fixing plate shaped like the Chinese character of 'tian'. The bolt holes are formed around the conical vertical tubes. A building steel column is connected to the bottom face of the fixing plate. The connecting piece is connected with one corner element or two corner elements or three corner elements or four corner elements. The building joint has the effects of being good in structure universality, flexible to splice, simple in structure and convenient to assemble and disassemble.

The invention discloses an interface structure of an electronic product and relates to the technical field of interfaces. The interface structure mainly aims at achieving the purposes that an integralstructure in which a wire is directly connected with a PCB is achieved, unified normative manufacturing is achieved, structural universality is great, design and manufacturing of complicated PCB pinboards are not required, and therefore the efficiency is improved. The structure includes a housing, a soft cable, the wire and the PCB. The PCB is arranged in the housing and consists of a PCB port; one end of the wire is electrically connected to a connection end of the PCB port; the soft cable at least wraps one end of the wire and the connection end of the PCB port. The interface structure is used for standardizing an interface of the electronic product.

Disclosed is a neutral gear and reverse gear switch structure in a gearbox. The neutral gear and reverse gear switch structure comprises a shell and a touch rod; the touch rod is arranged in the shell; the switch also comprises a switch core part; a core part mounting sinking table is arranged in the shell; a touch rod mounting sinking table is arranged in the middle part of the bottom surface of the core part mounting sinking table; a touch rod sliding hole is formed in the middle part of the bottom surface of the touch rod mounting sinking table; one end of the touch rod is matched with the touch rod mounting sinking table in a limiting manner while the other end of the touch rod is glidingly matched with the touch rod sliding hole; the lower end of the switch core part is matched with the top of the core part mounting sinking table in a tight clamping manner; and the bottom surface of the switch core part is matched with the core part mounting sinking table in a sealing manner through an oil-preventing membrane and a first sealing ring in sequence. The neutral gear and reverse gear switch structure is excellent in sealing property, capable of effectively preventing oil liquid from entering the switch, and high in durability and high in reliability.
