This utility model relates to an integrated wine cork opening mechanism, including a cork, a support pad, and a rotating handle. The cork is inserted into the bottle neck, and the support pad is fixedly installed on the top of the cork. The outer diameter of the support pad is larger than the outer diameter of the cork and the inner diameter of the bottle neck. The height of the support pad is greater than the height of the cork. The outer periphery of the support pad is provided with external threads. The top of the rotating handle is provided with a through hole, and the inside of the rotating handle is provided with a longitudinally extending clearance groove and an internal thread that meshes with the external threads. When the user needs to open the cork, he only needs to drive the rotating handle to rotate. Under the interaction of the internal and external threads, the support pad and the cork will rise simultaneously from the through hole, thereby pulling the cork out of the bottle neck. There is no need to find a corkscrew. Moreover, the diameter of the through hole is larger than the outer diameter of the support pad, and the rotating handle is movably fitted around the neck of the bottle, hardly increasing the original height of the wine bottle, thus facilitating packaging. The structure is ingeniously and reasonably designed to meet the needs of use.

The utility model relates to a new energy commercial refitted refrigerator car refrigerating unit, which relates to the technical field of new energy refrigerator cars, and comprises an inner machine assembly, an outer machine assembly, a pipeline assembly and a high-voltage junction box, the outer machine assembly comprises a refrigerating part integration component and a condenser, the refrigerating part integration component comprises a base and a scroll compressor arranged on the base, and the condenser is arranged on the base. The base is arranged below a chassis of the vehicle body and located on the side edge of the power battery, the condenser is arranged below the chassis of the vehicle body and located behind the power battery, and the indoor unit assembly, the scroll compressor and the condenser are connected through the pipeline assembly. The outdoor unit assembly is divided into the refrigeration part integration assembly and the condenser which are installed respectively, the height of the whole vehicle is not increased, heat dissipation is facilitated, installation and maintenance are facilitated, the vortex compressor is controlled to work through the high-voltage junction box arranged below the chassis of the vehicle body, the wiring arrangement of pipelines is simplified, and the working efficiency is improved. In this way, the convenience of installation and maintenance of the refrigerating unit of the new energy commercial refitted refrigerator car is improved.

The present disclosure provides a connecting female head, a connecting male head, a connecting structure and a cleaning device, and relates to the technical field of cleaning device and mechanical arm connecting structure. The connecting female head is configured to be connected with the connecting male head in a docking mode. The connecting female head comprises a first main body part, a recess, a first magnetic attraction part and a first wiring terminal. The first main body part is configured to be connected with the cleaning device through a connecting piece. The recess is arranged on the first main body part and is configured to cooperate with a convex part of the connecting male head, so that the connecting female head and the connecting male head move synchronously. The first magnetic attraction part is arranged on the first main body part and is configured to be magnetically attracted and fixed with the connecting male head. The first wiring terminal is configured to be matched with a second wiring terminal of the connecting male head for electrical connection in response to the docking of the recess and the convex part. The connecting female head and the connecting male head can be quickly connected and separated, facilitating the disassembly, replacement and the like of the mechanical arm and the cleaning device.

The utility model relates to the technical field of engines, and discloses an engine system and a vehicle. The engine system comprises an engine, a hydraulic retarder, a thermostat and a radiator. Wherein the engine comprises a water pump, a cylinder cover and a cylinder cover hood, the water pump is provided with a water inlet for cooling liquid to enter, and a cylinder cover water jacket for cooling liquid to flow out is arranged in the cylinder cover; an inlet of the hydraulic retarder is communicated with the cylinder cover water jacket through a liquid outlet pipe; the thermostat is provided with a flow inlet and a flow return port, and the flow inlet is communicated with an outlet of the hydraulic retarder; a liquid outlet of the radiator is communicated with the water inlet, and a liquid return port of the radiator is communicated with the backflow port through a liquid return pipe. Wherein the liquid return pipe and the liquid outlet pipe are arranged on the side wall of the cylinder head cover and above the cylinder head in parallel, and the highest point of the liquid return pipe and the highest point of the liquid outlet pipe are not higher than the highest point of the cylinder head cover. According to the technical scheme, the cooling pipelines of the engine system are reasonably arranged, and the engine system has high integration level.
