The utility model discloses a bridge expansion joint water-stop belt structure, and belongs to the field of water-stop belts. A bridge expansion joint water-stop belt structure comprises a water-stop belt body, the two ends of the water-stop belt body are fixedly connected with limiting strips A, a plurality of through holes are formed in the middle of the water-stop belt body, a drainage groove is formed in the lower side of the water-stop belt body, the two sides of the drainage groove are connected with connecting belts in a clamped and matched mode, the connecting belts are fixedly connected with the water-stop belt body, and the drainage groove is fixedly connected with a plurality of water guide plates. And the plurality of water guide plates are obliquely arranged. When rainwater and silt on a bridge floor flow to the water-stop belt body, the rainwater and the silt can flow into the drainage groove through the through holes, the rainwater can wash away the silt accumulated at the bottom of the drainage groove under the action of the guide plate, the silt can be rapidly discharged to the two ends of the drainage groove, and therefore the water-stop belt body is prevented from losing action, the service life of the water-stop belt body is prolonged, and the maintenance frequency is reduced. The practicability is high.

This utility model discloses an automatic diverting valve for vacuum pipelines, relating to the field of fluid control technology. The utility model includes a main pipeline with a flow-direction changing mechanism and a disassembly mechanism on its outer wall. By incorporating a valve plate, when the fluid direction needs to be changed, a controller starts a motor, which rotates a threaded rod. The rotation of the threaded rod moves a fixed frame, which in turn moves an internal rack, causing a bidirectional rack to move. This movement of the rack moves the valve plate, which, when it reaches another branch pipeline, compresses a pressure plate, thereby compressing the telescopic rod and spring. This mechanism, through the threaded rod driving the valve plate, closes the branch pipeline, changing the fluid flow direction. Simultaneously, the pressure plate enhances the seal between the valve plate and the branch pipeline.

The utility model discloses a sample constant-temperature preservation device for collecting pathogenic microorganisms, and particularly relates to the technical field of medical instruments, the sample constant-temperature preservation device comprises a moving assembly, the rear part of the moving assembly is fixedly connected with a fixed assembly, the front part of the moving assembly is rotatably connected with a placing assembly, and the moving assembly is fixedly connected with the fixed assembly. A containing plate is slidably connected to an inner cavity of the moving assembly, a constant-temperature assembly is fixedly connected to the inner cavity of the moving assembly, and a scraping assembly is rotationally connected to the front portion of the constant-temperature assembly. According to the sample constant-temperature storage device for collecting pathogenic microorganisms, the interior of the first shell can be cooled through the designed power assembly and the constant-temperature assembly, so that the interior of the first shell is always kept at a low temperature, and when the sample is placed for a long time, the sample cannot be deteriorated, so that the sample is prevented from losing the effect; the specimen for microbiological examination can be preserved at low temperature for 24 hours at most, and the temperature range is beneficial to keeping the activity of microorganisms.

The utility model relates to the technical field of research, development and design of computer accessories, in particular to a fixing structure of a heat dissipation device, which comprises a heat dissipation device body, a support and a fixing piece, the heat dissipation device body is assembled on the support, the fixing piece is provided with an insertion hole corresponding to the fixing piece, and the heat dissipation device body is inserted into the insertion hole. One end of the fixing piece is assembled in the radiator body through the inserting hole, a first installation hole is formed in the other end of the fixing piece, and a second installation hole corresponding to the first installation hole is formed in the support. And the other end of the fixing piece is assembled on the bracket through the matching of the mounting piece, the first mounting hole and the second mounting hole. The structure disclosed by the utility model has the advantages that the structure disclosed by the utility model can effectively resist impact caused by external forces such as bumping, collision and extrusion in a transportation process; the risk that the heat dissipation device is damaged in the transportation link is reduced, and performance reduction and service life shortening caused by transportation damage are avoided.
