A danger indicating device for highway engineering comprises a main indicating board (1) and an auxiliary indicating board (2) arranged on the main indicating board in a sleeving mode. The outer plate surface of the main indicating plate and the outer plate surface of the auxiliary indicating plate are provided with rectangular concave plate surfaces, indicating plate screw holes (15) are machined in the four corners of each concave plate surface respectively, the concave plate surfaces are sequentially covered with a warning board and a transparent plate, mounting holes are machined in the four corners of the transparent plate, and mounting screws (14) penetrate through the mounting holes and then are screwed into the indicating plate screw holes, so that the warning board is formed. The transparent board and the warning board are clamped and installed on the main indicating board and the auxiliary indicating board respectively; supporting mechanisms which are used in a matched mode are arranged in the main indicating board (1) and the auxiliary indicating board (2) respectively. The warning device can be drawn and pulled, is convenient to carry and transport, facilitates replacement of warning content, and is convenient to stably place and install.

A wireless charging system for automobiles includes a ground-based power transmitting platform and an on-board power receiving platform. The ground-based power transmitting platform is mounted on the ground and is elastically deformable in the vertical direction. The on-board power receiving platform is mounted on the chassis of the automobile. When the automobile is charging, the on-board power receiving platform presses against the ground-based power transmitting platform, which is in a compressed state. By setting up the ground-based power transmitting platform on the ground and the on-board power receiving platform on the chassis of the automobile, the two platforms are in close contact during charging. The ground-based power transmitting platform is in a compressed state, maintaining a pressing relationship, thus eliminating the need for foreign object detection and liveness detection. The system is simple, small and compact, and improves charging efficiency.

The application discloses a portable grinder, which belongs to the technical field of household appliances and specifically relates to a portable grinder which comprises an upper shell, a grinding part arranged at the lower end of the upper shell, and a lower cup body. The grinding part comprises a driving shaft rotatably connected to the lower end of the upper shell, a conical head fixedly connected to the lower end of the driving shaft, and a grinding blade fixedly connected to the lower end of the conical head. A driving motor is fixedly connected to the inside of the upper shell, and the output shaft of the driving motor is fixedly connected to the driving shaft. The conical head is arranged on the driving shaft, and the conical head is located above the grinding blade. When the material moves and falls in the lower cup body, the conical head first receives the falling material. The conical surface of the conical head disperses the material to all directions, guides the material to be evenly spread in the radial direction, and then the material falls on the lower grinding blade, so that the direct impact on the center of the blade (usually the most fragile or stress-concentrated area) is reduced, the connection between the blade and the transmission shaft is protected, the service life of the blade is prolonged, and the failure risk is reduced.

The utility model discloses a portable transducer clamp relates to transducer technical field for solving the technical problem of traditional transducer clamp structure complex, inconveniently portable and inconvenient installation, a portable transducer clamp, including with longitudinal watertight joint hole's transducer fixed frame, the bottom of transducer fixed frame is connected with base by fixed link, the top of transducer fixed frame is provided with the connecting mechanism for with rope is connected, transducer fixed frame and base adopt POM material to make, by this, the utility model has simple structure easy to install, all -round protection, light weight easy to carry etc. advantage, solved the technical problem existing in the prior art.

The utility model relates to material transferring equipment which comprises a hanging frame carrying table, a material hanging frame horizontally and rotatably arranged on the hanging frame carrying table, a roll shaft transferring module horizontally transferring the hanging frame carrying table and an adjusting module adjusting the horizontal rotation angle of the material hanging frame entering the roll shaft transferring module. The rotating platform module is used for driving the hanger carrying table, the roll shaft transferring module and the adjusting module to synchronously and horizontally rotate; the multiple material hanging frames are arranged, and the adjusting module is arranged below the roller shaft transferring module. According to the scheme, the equipment is suitable for multi-row hanging tools for automatic feeding and discharging, more products can be stored in a limited space, the number of times of manual feeding and discharging of empty and full hanging tools is greatly reduced, and the continuous operation time is prolonged; and more materials can be hung and transferred through the multiple material hanging racks on the multiple hanging rack carrying tables, the space utilization rate is high, and the overall size is compact and small.

The utility model belongs to vehicle engineering technical field, concretely is a kind of armored vehicle turret posture control mechanism, including front cover;The front cover end portion is rigidly connected with shell;The front cover end portion is rigidly connected with back cover;The shell lateral wall is equipped with aviation plug;The input shaft is rotatably connected in the middle part of the front cover and back cover, and the input shaft outer wall is equipped with rotating handle;Its characterized in that: the shell inner wall is rigidly connected with boss;Multiple sets of connecting holes are arranged in the middle part of the shell;The middle part of the shell is equipped with mounting hole, and plug is installed in the inner wall of mounting hole;Multiple sets of first through holes are arranged in the bottom of the shell;The shell inner part is three functional areas, uses electric signal as the feedback mode of turret posture control mechanism, removes the transmission and the large amount of mechanical transmission components, such as speed reduction mechanism, etc. in the traditional structure using gear, and the present mechanism uses modularization package, so it is small and exquisite compact.
