The application discloses a kind of LKJ simulation training platform human-computer interaction equipment, comprising: shell, the side of the shell is equipped with display device and control button;And disinfection device, be equipped on shell, for the surface disinfection of display device and control button.It is provided with disinfection device on shell, by driving member drives pull rope turnover piece, so that pull rope turnover piece pulls and is cleaned piece from horizontal state rotates to vertical state and then moves from the one end of guide pillar to the other end, in the process of movement, cleaning piece disinfects the surface of display device and control button, prevent dust and bacteria etc. from causing damage to display device simultaneously also prevent bacteria from spreading between different training personnel, when cleaning piece moves to the other end of guide pillar, it is automatically rotated from vertical state to horizontal state and resets and moves to the initial position of guide pillar, realize that cleaning piece is automatically stowed, do not affect the use of the human-computer interaction equipment.

The utility model relates to headrest folding technical field discloses a kind of foldable storage's car seat headrest support structure, including seat, the headrest rod is installed in the seat, the similar side of multiple headrest rods is fixedly connected with locking leaf, the lower end of multiple locking leaf is fixedly connected with rotating center rod between adjacent, rotating center rod middle fixed mounting multiple limit stake, the outer wall left and right sides of rotating center rod are rotatably connected with lock plate, spring two is installed in the rotating center rod outer wall between multiple lock plate and limit stake.The utility model in the prior art, when needing to fold headrest, exert force on back cover, and then will act on connecting rod, the force received by connecting rod will act on the top of lock plate, and at the same time, spring two mounted on rotating center rod will be applied, so that the lock plate will rotate under the action of spring two.

This utility model discloses a ground-mounted plastic greenhouse for aquaculture, specifically relating to the field of aquaculture greenhouse technology. It includes multiple greenhouse support rods, with a plastic film sandwiched between the support rods. A fixing plate is fixedly connected to the bottom of each support rod, and a retraction mechanism is provided between the support rod and the fixing plate. The retraction mechanism includes an arc-shaped tube fixed to the top of the fixing plate, and a sliding sleeve is slidably connected to the outer side of each support rod. This utility model, by setting up a retraction mechanism and a winding mechanism, uses a motor-driven winding roller to control the retraction of the connecting rope, thereby causing the sliding sleeve to slide on the support rod. This achieves assisted unfolding and automatic retraction of the plastic film, eliminating the need for manual operation, saving manpower, and quickly completing the retraction of the plastic film, thus improving work efficiency. Especially when rapid response to weather changes is required, the plastic film can be unfolded or retracted in a timely manner, providing a good environment for aquaculture.

The utility model discloses a child's pushchair framework, bottom support frame includes front leg and with the rear leg rotatable connection of front leg, and the lower extreme of front leg and rear leg is equipped with the wheel, and the upper end rotatable connection of bottom support frame has the support rod, and the upper end rotatable connection of support rod is close to the lower extreme position of hand push pole and is connected, and the transmission rod articulated with both is equipped between the lower extreme of hand push pole and rear leg, and the linkage rod articulated with both and can drive the traction assembly activity when transmission rod rotates folding or unfolding relative to rear leg is equipped between transmission rod and close to its lower extreme position and traction assembly, and the rear side rotatable connection of seat frame upper end and rear leg, and the connecting rod articulated with both and can drive seat frame relative to front leg close or unfold when traction assembly drives front leg and rear leg close or unfold is equipped between seat frame front side and traction assembly. The utility model discloses simple structure, and the nimble folding.

This invention discloses an intelligent temperature-sensing explosion-proof unmanned aerial vehicle (UAV) for tunnels, relating to the field of UAV technology. It includes a fuselage, wings, and a detection system. A mounting frame for the detection system is installed on the fuselage. A drive wheel is rotatably mounted on the mounting frame and connected to a first drive mechanism. A rotating frame is rotatably mounted on the drive frame, with one end connected to a second drive mechanism and the other end housing the detection unit. Through the cooperation of the first and second drive mechanisms, the detection unit can achieve full-angle rotation in the horizontal direction and adjustment of the pitch angle in the vertical direction, significantly improving the detection field of view. The detection unit is equipped with a cleaning mechanism that utilizes the Venturi effect to adsorb dust and has a self-cleaning function. The wings automatically fold and unfold via a planetary gear set and a locking mechanism. This invention has a compact structure, flexible and reliable detection capabilities, and is suitable for complex environments such as tunnels.
