The invention relates to table lamp treatment equipment. The table lamp treatment equipment comprises a base plate, a limiting device, a hollowed-out clearing device, a wrinkled clearing device, an auxiliary device and a cleaning device. The limiting device is installed at the rear end of the base plate. The hollowed-out clearing device is installed at the left end of the base plate. The cleaningdevice is installed at the right end of the base plate. The wrinkled clearing device is installed in the middle of the front end of the base plate. The auxiliary device is installed on the left side of the front end of the base plate. The table lamp treatment equipment can solve the difficult problems that lamp covers of different materials and structures need to be cleaned in a targeted mode by people under the condition of fixing the lamp covers in an existing lamp cover cleaning process, when the lamp covers are fixed, one hand of people needs to limit the lamp covers and the other hand ofpeople needs to clean the lamp covers; when a hollowed-out part is cleaned, people need to clean the hollowed-out part with toothpicks; when a wrinkled part is cleaned, people need to clean the surface of the wrinkled part with the help of tools; and when the lamp covers of different materials are cleaned, people need to clean the lamp covers of different types in a targeted mode.

The invention relates to the field of electric vehicles, in particular to an electric tricycle for transportation; it includes a car body, a carriage and a motor; the top of the car body is fixedly connected with a carriage; The inside of the block is fixedly connected with a motor; the output shaft of the motor is fixedly connected with a first bevel gear; the surface of the connecting block is connected with a screw rod for rotation; the surface of the screw rod near the top of the screw rod is fixedly connected with a first Two bevel gears; the surface of the nut of the screw mandrel is fixedly connected with a connecting rod; the surface of the connecting rod near the bottom of the connecting rod is rotatably connected with a pressure plate; through the present invention, the tail of the electric tricycle is increased with an automatic lifting function part , which is convenient for workers to load and unload goods and passengers to ride, reducing the work intensity of staff loading and unloading goods. At the same time, for special people, the pressure plate can be directly up and down automatically, without more auxiliary personnel, which is convenient for special personnel. Travel short distances quickly.

The invention discloses hollow glass with a built-in sun-shading curtain. The hollow glass comprises two glass media, the sun-shading curtain between the two glass media and a traction mechanism for controlling the sun-shading curtain, as well as a traction device fixed on the traction mechanism; an operation device is arranged outside the hollow glass and is opposite to the traction device; at least one of the operation device and the traction device contains magnetic material, and the operation device and the traction device are in magnetic connection; and at least one of the operation device and the traction device is provided with a first support structure, a first rotating shaft is fixed on the first support structure, a rolling wheel with a resistance position is mounted on the first rotating shaft, and at least two positions where the rolling wheel which are in contact with the hollow glass are nearest to the first rotating shaft in one rotation cycle of the rolling wheel. As the rolling wheel with the resistance position is selected, when the sun-shading curtain stops the motion, the sun-shading curtain is not only under the action of the friction force of the contact surface, but also is regulated by the component force of magnetic force in the horizontal direction, and the hollow glass further has the automatic position-limiting function, the operation difficulty is reduced and the operation hand feeling is improved.

The invention belongs to the field of life, and particularly relates to an automatic anti-skid tray and a use method thereof. The anti-skid tray comprises a tray body; the tray body is internally provided with a liquid storage cavity; the liquid storage cavity is filled with gasification liquid with the low boiling point; the upper end of the tray body is fixedly connected with a heat conduction sheet; the lower end of the heat conduction sheet is fixedly connected with a plurality of heat conduction rods; the lower ends of the heat conduction rods extend into the liquid storage cavity; an annular cavity communicating with the liquid storage cavity is formed in the tray body; an annular opening communicating with the annular cavity is formed in the side wall of the liquid storage cavity; an air bag is fixedly connected in the annular opening; a plurality of annular plates are arranged on the upper side of the air bag; and the diameters of the multiple annular plates are sequentially increased from inside to outside. The temperature of a utensil is utilized for heating the gasification liquid with the low boiling point, the gasification liquid is vaporized and fills up the air bag,a limiting rod is jacked by the air bag, and the utensil is limited, so that the utensil is prevented from sliding on the surface of the tray and the situation that soup in the utensil overflows or the utensil falls to the ground is greatly reduced.
