The invention discloses an assembly type underground garage. The garage comprises underground walls, a top plate, a bottom plate and at least three middle parking layers. Permanent upright columns are vertically arranged in the underground garage. The top plate and each middle parking layer both comprises a purlin supporting the corresponding underground wall, an oval ring bracket abutting against the inner wall of the purlin, two first supporting beams and a plurality of second supporting beams, wherein the two ends of each first supporting beam abut against the oval ring bracket and are supported on the corresponding permanent upright column, and the second supporting beams are supported between the first supporting beam and the oval ring bracket. The bottom parking layer is arranged on the bottom plate. The bottom parking layer and each middle parking layer are both provided with a vehicle carrying board capable of moving. Reinforcing treatment is conducted between prefabricated components of the underground garage, the integrity of the underground garage structure is improved, and accordingly the anti-seismic property of the underground garage is improved. The invention further discloses a building method of the underground garage.

The invention discloses a device for vapor deposition of films. The device comprises an upper reaction cavity cover, a reaction cavity base and a heater. The reaction cavity base is used for bearing substrates and is movably connected to the upper reaction cavity cover for forming a vapor deposition reaction cavity, and the back of the reaction cavity base makes contact with the heater for conducting heat. The reaction cavity base is round and is provided with an annular groove. The device for vapor deposition of the films can guarantee that the whole reaction cavity will not be deformed seriously, and therefore the uniformity of the films can be guaranteed.

The invention provides a clearance adjustment mechanism for an automobile steering device. The clearance adjustment mechanism comprises a steering device shell and further comprises a pressing seat embedded in the steering device shell in a sliding manner, and an adjusting part which is connected to the interior of the steering device shell and abuts against the pressing seat. Under the external force drive, the position of the adjusting part is changed in the steering device shell so that the pressing seat can slide in the axial direction of the steering device shell. Two elastic supporting arms which are oppositely arranged and have supporting faces are formed on the pressing seat. A blocking limiting part which can limit external expansion of the two elastic supporting arms through self blocking is further arranged on the pressing seat. By means of the clearance adjustment mechanism for the automobile steering device, the engagement effect between a rack and a gear can be ensured, the engagement clearance between the rack and the gear can be adjusted, damage of the pressing seat due to colliding and impacting can also be avoided, in addition, an existing spring structure is omitted, adverse influences caused by changing of spring force can be avoided, and a good use effect is achieved.

The invention discloses a supporting joint with a U-shaped steel plate. The supporting joint is mainly composed of a U-shaped steel plate, a cushion plate, a long-strip installing hole and a suspender; the cross section of the U-shaped steel plate is in the shape of U or groove, the upper end of the U-shaped or groove-shaped opening is provided with wing edges, wherein one wing edge is overlapped on a connection structure, and the other one wing edge is overlapped on a multi-tower structure; one end of the suspender is crossed through the middle part of the wing edge at one side of the U-shaped steel plate and connected with the connection structure, and the other end is connected with a bracket of the multi-tower structure; a long-strip installing hole is arranged on the wing edge of the U-shaped steel plate connected with the connection structure along the axial direction, and long-strip installing hole is connected with the connection structure through a bolt or an anchor; the wing edge at the other side of the U-shaped steel plate is connected with the multi-tower structure through the bolt or the anchor. The supporting joint with the U-shaped steel plate is simple in structure and convenient to construct; besides, the supporting joint is simple and reasonable in stress, and can be recovered in small shock and repaired in big shock; particularly, the supporting joint plays the functions of 'relative isolation' and 'fuse wire' to the connection structure and the multi-tower structure; besides, the practicability is strong.

The disclosure relates to a slide rule for learning decimal elements, which includes a base body, in which a plurality of parallel chute is arranged in a row, and a sliding sheet is arranged in the chute, and the hundred element is marked on the sliding sheet, and a plurality of sliding slots are arranged in the chute. The sheets can independently expand and contract along the chute so that the different slides are exposed outside the base. The present disclosure facilitates the learning of decimal elements.

The improved cushion structure of the present invention includes a body and an elastic body; the body has a first end and a second end, the first end is provided with a nose pad, and the second end of the body is provided with two tails pad, a connecting portion is formed between the nose pad and the two tail pads, and the body forms a recessed space between the nose pad and the tail pad and on the upper side of the connecting portion; the elastic body is combined with the In the recessed space of the body, it is used to support the external genitalia of the rider and avoid excessive compression, and at the same time, the design of the seat cushion can obtain a more beautiful overall appearance.
