This invention discloses a personalized Gothic arch component for dental implant restoration and a method for determining digital jaw position relationships, belonging to the field of medical device technology. The component includes a mandibular tracing needle fixation bracket, a tracing needle, a maxillary Gothic arch tracing plate, and fixing screws. The mandibular tracing needle fixation bracket comprises a Y-shaped tracing needle positioning frame and a personalized implant fixation bracket. The tracing needle is fitted into the central groove of the mandibular tracing needle fixation bracket via a shaft-hole fitting structure. The maxillary Gothic arch tracing plate is U-shaped and adapts to the maxillary dental arch. Both the mandibular tracing needle fixation bracket and the maxillary Gothic arch tracing plate are provided with screw channels for matching fixing screws. The method for determining digital jaw position relationships includes: taking a digital impression; designing and 3D printing the above components using CAD / CAM; determining the vertical distance and centric relationship using the personalized Gothic arch; and transferring the maxillary-mandibular relationship for edentulous full-mouth implant restoration based on occlusal records and electronic facebow data, thereby improving the clinical applicability of the restoration.

The embodiment of the invention provides an automobile transport ship deck structure and a ship. According to the deck structure, a deck in the lower area of a cargo hold is in a continuous sheet deck form; a deck in the upper area of the cargo hold adopts a steel framework steel plate deck form; and the structural strength of the hull meets the design requirement. According to the embodiment of the invention, the number of continuous decks at the upper part is reduced, the continuous decks are changed into a frame structure, small thin plates are laid on the frame, and the structure is reinforced, so that on the premise that the structural strength requirement of the ship body is met, the thin plates are prevented from being damaged in the processes of cutting, blanking, assembling, welding, placing, transferring, turning over, hoisting and the like; and a large amount of inevitable repairing work caused by deformation is avoided, so that the construction cost is reduced, the construction time is shortened, and the safety and economical efficiency of the ship structure are improved.

The utility model belongs to new energy technology field, especially point to a kind of flexible photovoltaic carport, including the main stand and main support beam of transverse interval arrangement, several steel strands are arranged on two main support beams, and the both ends of steel strand are anchored in tension with main support beam, several longitudinal oblique drainage channels are arranged on the steel strand between two main support beams, longitudinal oblique drainage channel is connected with steel strand by first connecting piece, and photovoltaic panel assembly is spliced and is laid flat on the top of the canopy formed by main support beam and steel strand by second connecting piece installed on longitudinal oblique drainage channel;The utility model forms canopy bearing structure by the steel strand of transverse arrangement and main support beam, need not set up transverse purlin, reduce material cost and assembly complexity.

The application provides a bearing bracket suitable for normal placement of a thin plate segment and a design method thereof. The design method designs two types of general brackets corresponding to the structure interval according to the structure size of the thin plate segment and the total segment. The two types of brackets are calculated and analyzed by using a finite element calculation method, and the brackets meet the structural strength requirement. The finite element calculation and analysis of the normal placement scheme of the selected typical thin plate segment meet the accuracy construction requirement of the deformation of the segment and the bracket. The bracket structure is simple and reusable, has strong universality, can be suitable for the normal placement scheme of thin plate segments of various sizes, effectively controls the structural deformation of the thin plate segment, and provides favorable conditions for ship production and manufacturing transportation.

The utility model discloses a kind of connection structure of centrifugal fan volute and motor, including volute, volute side fixed connection damping component, the side of damping component away from volute is equipped with suction component, part structure of the suction component is inserted into volute and penetrates damping component, one is directly blocked vibration energy along the path of linear penetration rubber layer, avoid energy direct transmission;Two are forced vibration wave at the interface of staggered sheet and rubber repeatedly occurs reflection and scattering, significantly improve the dissipation efficiency of vibration energy, to further weaken vibration transmission intensity.
