A swing arm type mortise and tenon joint
ActiveCN224591973URealize three-dimensional adjustable functionAdjust the relative gap
This utility model discloses a hinged structure with a rotating arm, which is mainly composed of a door leaf fixing component assembly, a rotating arm assembly, a door frame fixing seat, and a shaft A. The door leaf fixing component assembly includes a door leaf hinge, a shaft B, a bushing, a flat-head screw A, a T-shaped adjusting foot, a flat support A, and a positioning device A. The mounting plate of the door leaf hinge is provided with at least a screw hole A and a mounting hole A for installing the T-shaped adjusting foot. Adjusting the T-shaped adjusting foot can easily adjust the relative gap between the door leaf and the door frame. The rotating arm assembly includes a rotating arm A, a positioning device B, a countersunk screw A or a flat-head screw A. The positioning device B includes a tubular device body, a compression spring B, and a steel ball A. The rotating arm A is connected and fixed to the rotating arm B (23) through the connecting part A and the connecting part B of the rotating arm A (23) with a countersunk screw A to form a space A for concealing the door leaf cover sealing strip and a space B for the door frame clearance.

An EGR check valve and an EGR system
ActiveCN224282797UOpen resistance is smalllarge opening angleInternal combustion piston enginesExhaust gas recirculationExhaust fumesCheck valve
This application discloses an EGR one-way valve and an EGR system. The EGR one-way valve includes a base and a valve plate. A rotating shaft is provided at the fixed end of the valve plate, and a bushing is provided on the base. The valve plate is rotatably connected to the base through the bushing that cooperates with the rotating shaft. The opening of the valve plate of the EGR one-way valve disclosed in this solution is affected by the friction between the rotating shaft and the bushing. The friction between the rotating shaft and the bushing is much smaller than the restoring force generated by the deformation of the valve plate in related technologies, which reduces the opening resistance of the valve plate and increases the opening angle of the valve plate, thereby reducing the exhaust gas resistance and helping to improve the engine EGR rate. By changing the fixing method of the valve plate, the valve plate does not deform during the opening process, and the valve plate does not block the opening area, increasing the opening area at the same opening angle. At the same time, the valve plate does not deform, reducing the risk of the valve plate breaking due to frequent opening and closing, and extending the service life of the valve plate.

Multi-lattice bin disposable stacked double-fold eyelid sticker storage box
ActiveCN224090703UExtended service lifeImprove practicalityNon-removalbe lids/coversInternal fittingsStructural engineeringMechanical engineering
The utility model relates to the technical field of storage boxes, and discloses a multi-lattice bin disposable stacked double-fold eyelid sticker storage box which comprises a storage box body. The storage box is made of acrylic materials, so that the whole storage box looks more exquisite and attractive, the partition plates are fixed on the inner wall of the storage box, different types of double-fold eyelids can be stored in a separated mode through the partition plates, the different double-fold eyelids are prevented from being intertwined, a user can store and take the double-fold eyelids conveniently, and the practicability of the whole storage box is improved; a sleeving groove is formed in the outer wall of the storage box and avoids the plastic sealing cover, meanwhile, a plastic clamping block is fixed to the outer wall of the sleeving groove, when the plastic clamping block makes contact with the first plastic clamping block, the plastic sealing cover can be fixed and prevented from being accidentally opened, and a flexible connecting plate is fixed to the outer wall of the storage box, so that the plastic sealing cover is prevented from being accidentally opened. The flexible connecting plate and the plastic sealing cover are fixed, the plastic sealing cover and the storage box are connected through flexible plastic, and meanwhile the flexible connecting plate prevents the opening angle of the plastic sealing cover from being too large.

Intelligent intercepting well based on gear rotating weir gate and electric flow limiter
The invention relates to the technical field of municipal drainage, rain and sewage diversion and water pollution control, in particular to an intelligent intercepting well based on a gear rotating weir gate and an electric flow limiter, which comprises a well body structure, a gear driving rotating weir gate unit, an electric flow limiter unit, a sensing monitoring unit and an intelligent control unit. The intelligent control unit obtains information such as upstream incoming water total amount, rainfall intensity, pollution concentration and downstream liquid level, solves target interception flow, and performs cooperative control according to an opening-flow mapping relation and an angle-diversion capability mapping relation in a sequence of firstly controlling the electric flow limiter unit and then controlling the gear-driven rotary weir gate unit. Therefore, dynamic optimization of closure and diversion is realized, and pollution control, flood drainage safety and system operation reliability are considered.
