The utility model discloses a kind of display cabinets for food sales, including main body, closed mechanism, extension mechanism and display mechanism, the closed mechanism includes closure door and locking piece, the extension mechanism includes extension rod and positioning piece, the display mechanism includes show stand and display lamp, under the mutual cooperation of above mechanism, the device can avoid food exposed in air, prevent dust, bacteria, insect pollution, improve health safety, thereby prolong the fresh-keeping time of food, reduce waste, in addition, the device increases the effective display area of display cabinet, it is especially useful when large or food variety, temporarily expand space, no additional equipment is needed, high flexibility.

The invention discloses a supporting frame for computer hardware teaching demonstration, and relates to the field of teaching supporting frames, the supporting frame comprises a supporting seat and a supporting cylinder arranged in the supporting seat, the supporting cylinder is slidably provided with a bearing box, the bearing box is internally provided with an upper layer cavity and a lower layer cavity, and the upper layer cavity is internally provided with a placing box; a placing plate is arranged in the lower-layer cavity, a control assembly is arranged in the supporting cylinder, a handle is fixedly arranged on the supporting cylinder, a first unfolding assembly is arranged in the handle and the upper-layer cavity, and a second unfolding assembly is arranged in the lower-layer cavity. During demonstration, the bearing box ascends, the placement box and the placement plate are unfolded to form a three-dimensional display space, the space utilization rate is maximized, the placement plate is in an inclined state, students in the back row can easily and clearly see the whole view and layout of the plate surface, the problem that the sight is blocked during static flat placement is solved, and the teaching efficiency of teachers is improved.

The application discloses a data comprehensive situation display method based on a recommendation model, constructs a data analysis recommendation model for data classification and fusion according to a special topic or a label dimension for global data in a background database, customizes a statistical analysis front visual chart plug-in, and binds and displays a front visual chart plug-in display framework and special topic data associated by the background data analysis recommendation model, customizes an embedded method for changing and displaying the display framework structure and layout of the front visual chart plug-in with time stages, integrates and analyzes the background data associated with the recommendation model to bind the front visual plug-in display framework for display and a front visual plug-in display framework dynamic change method, and realizes the process of dynamically pushing the background data to the front and visually customizing and displaying in the whole time flow and cycle.

The utility model provides a refrigerator drawer assembly, include: drawer assembly and storage component, the lower surface of drawer assembly is installed with the storage component for storage, the drawer assembly includes the drawer body for storage, the inside slide of drawer body is installed with the baffle one for separating space, baffle one sets up many groups, the storage component includes the storage box for storage, the inside magnetic attraction of storage box is installed with the baffle two for separating space, compared with prior art, the utility model has the beneficial effects as follows: through setting up drawer assembly, when using, drawer assembly and storage component cooperate, make the refrigerator internal article classification more definite, the storage groove one of drawer body is placed and does not need semi -sealed storage article, the lower storage component specially stores the thing needing semi -sealed storage, through baffle one and baffle two further subdivides the area, lets the refrigerator inside present the state of neat and orderly.

This invention relates to the field of railway freight positioning technology, specifically a railway freight positioning method and system based on BeiDou and multi-sensor fusion. The method includes: constructing a dynamic positioning observation model with BeiDou coordinates, inertial measurement unit output, wheel axle speedometer output, and environmental monitoring data as initial inputs; performing spatiotemporal consistency registration on multi-source heterogeneous positioning data to form a spatiotemporally synchronized observation sequence; establishing a positioning information flow and constructing a positioning observation confidence distribution map, separating high-confidence and low-confidence observation information; iteratively calibrating the dynamic positioning observation model using high-confidence observation information; reconstructing low-confidence observation information using the calibrated model, fusing the two to generate a globally consistent fused positioning result; performing a continuity check on the fused positioning result, and outputting the final positioning information. This method can improve the consistency and effectiveness of railway freight positioning and is adaptable to complex operating scenarios.
