The utility model relates to the field of integrated cookers, and particularly discloses a handle-free drawer structure, which comprises a main body and a drawer arranged at the front end of the main body in a drawable manner, a drawer door is arranged in front of the drawer, a light-transmitting area is arranged on the drawer door, a sensor is arranged in the light-transmitting area in the drawer, the sensor is fixed on the main body, and the handle is fixed on the main body. A pushing mechanism capable of ejecting the drawer out is arranged on the main body, the sensor is connected with the pushing mechanism, and when the light-transmitting area is shielded by an external object, the sensor senses the condition and drives the pushing mechanism to eject the front end of the drawer out of the main body. A handle does not need to be designed, the front end of the drawer can extend out of the main body only by blocking the shading area with a hand during use, and then the drawer is convenient to pull; the appearance structure is simple, dust is not easy to deposit after no handle is arranged, and cleaning is convenient.

This utility model discloses a water-pumping structure for a pet water fountain, including a base supporting a water tank. The base houses a rotary drive assembly comprising a drive motor, a magnetic turntable connected to the motor, and magnets mounted on the turntable. A water-pumping assembly is located at the bottom of the water tank, including a water inlet cover connected to a water inlet slot, a magnetic rotor within the water inlet cover, and a water delivery pipe connected to the water inlet cover. When the motor rotates, the rotary assembly uses magnetic force to drive the magnetic rotor of the water-pumping assembly to rotate. The centrifugal force generated by the rotating magnetic rotor draws water into the water inlet cover, through the water channel, and into the water delivery pipe, from where it is transported upwards to the water tray. This utility model, through the separate base, water tank, and water-pumping structure, not only achieves complete separation of water and electricity in the pet water fountain and reduces manufacturing and maintenance costs, but also makes cleaning the pet water fountain simple, easy, and thorough.

The utility model relates to the technical field of building engineering, especially interlaced steel structure module's connecting joint of stacking. The utility model discloses two groups of connecting components oppositely arranged up and down, every connecting component includes the horizontal setting connecting end plate, the outer sleeve and inner sleeve that are all connected with the connecting end plate perpendicularly and are horizontally interval arrangement, and the inner wall on the outer sleeve and the outer wall on the inner sleeve all are equipped with annular protruding, two connecting components with its connecting end plate and outer sleeve are connected in the bottom of upper module and the top of lower module, the outer sleeve and inner sleeve located in the upper can be inserted with the inner sleeve and outer sleeve located in the lower, and the inner sleeve after corresponding insertion is located in the inside of outer sleeve and forms the grouting space between both. Through being equipped with annular protruding on the inner wall of outer sleeve and the outer wall of inner sleeve, it can enhance the anti -pulling capacity of connecting joint, and the structure appearance is simple, and the production difficulty is reduced obviously.

The utility model relates to photovoltaic support technical field discloses the prefabricated concrete structure for photovoltaic support installation, it includes the window machine, the bottom movable joint of window machine has the bottom plate, the surface fixed connection of bottom plate top has the slide rail, the surface fixed connection of bottom plate is located the limit stop at slide rail both sides, the surface screw thread connection of bottom plate is located the limit stop one side has bolt. The sleeve frame for fixing photovoltaic support can use nut and first threaded column to carry out the convenient dismounting, using connecting plate and nut, utilizing second threaded column and third threaded column on concrete pier, multiple concrete piers can be connected together, make the lower structure of photovoltaic support whole more stable, the through slot structure on connecting plate can satisfy the connecting demand of different interval concrete pier, multiple connecting plate combination, still can make the array type arrangement connection of large quantity concrete pier, to satisfy the layout demand of large area photovoltaic panel.
