The invention provides a lifting furniture device used for a small apartment type house. The lifting furniture device comprises a bed body, a rectangular groove is formed in the top face of the bed body, a plurality of scissors-fork type mechanisms are hinged to the bottom face of the rectangular groove, a bed board parallel to the top face of the rectangular groove is arranged in the rectangulargroove, and the bed board and the scissors-fork type mechanisms are hinged. Two longitudinal first rotary shafts are arranged on one side on the upper portion of the bed body, gears on the two first rotary shafts are meshed with each other, and transverse second rotary shafts are arranged on the front side and the rear side on the upper portion of the bed body respectively. It can be achieved thatspace is effectively utilized, a user does not need to move away other furniture below the bed body, it is achieved that the bed body ascends and descends through a motor, and the user cannot place the furniture higher than 80 centimeters below the bed body. When people are at rest, an anti-mosquito effect can be achieved, in summer, wind from a fan or an air conditioner can be blocked, and the situation that the wind from the fan or the air conditioner is directly blown to the user, so that the user does not feels well is avoided. The lifting furniture device can be used as a cot bed to be used in a theme hotel, residents in the hotel can obtain novel residential experience, the curiosities of people are easily seized, and the occupancy rate of the hotel is increased.

The invention provides a roller shutter door and window, which is characterized in that each shutter blade is of a structure provided with U-shaped clamp openings at the two ends; the top of each shutter blade is provided with an upper hook body; the upper part of each shutter blade is provided with an upper rotating part; each curtain blade is of an arc-shaped structure; the top end of each curtain blade is provided with a lower rotating part; each upper rotating part is matched with the corresponding lower rotating part; an upper clamp groove and a lower clamp groove are formed in the inner surface of each curtain blade; the middle part of each curtain blade is provided with a plurality of sieve screen-shaped through holes; the middle part of each lower clamp groove is provided with a sound absorption rubber strip; the upper end and the lower end of each end clamp are provided with projected parts; each end clamp is matched with the upper clamp groove and the lower clamp groove which are formed in the corresponding curtain blade through the projected parts; the projected part of the lower end of each end clamp is matched with the corresponding lower clamp groove and just reaches the position of the corresponding sound absorption rubber strip; and the bottom of each curtain blade is provided with a lower hook body. The requirements of an inhabitant can be comprehensively met; by combining a main body with the shutter blades, the regulation can be effectively performed according to the requirements of the inhabitant; the ventilation effect is achieved, and meanwhile, a good insect prevention effect is achieved; and a prying-resistant function, a anticollision function, a sound absorption function and a convenient-to-repair function are also added.

The invention discloses an LED light source with a long range and a wide range, which belongs to the technical field of lighting equipment, and includes a light source assembly. Spotlight. In the present invention, through the cooperation of the designed first concentrating component, heat dissipation component and control component, the divergence angle of the light can be adjusted on the propagation path of the concentrating light, the brightness can be increased, and the concentrating effect is very good. It improves the penetration of light, effectively increases the range and radiation range of light, and reduces the loss of electric energy, achieving the effect of energy saving and emission reduction, and the air filter plate can absorb the moisture introduced into the airflow in the connection cover Harmful substances such as dust and dust are isolated outside, and the external conduction effect of high-temperature air is used to realize the drying treatment of the air filter plate, and to remove impurities in the filter holes of the air filter plate, ensuring the air purification treatment effect of the air filter plate.

The invention belongs to the field of power distribution cabinets, and in particular relates to an insect-proof power distribution cabinet for a communication base station, which includes a cabinet body, the side wall of the cabinet body is provided with a ventilation opening, and the inner side wall of the ventilation opening is fixedly connected with a The heat dissipation ring, the inner ring side wall of the heat dissipation ring is sealed and rotatably connected with an annular rotating plate, the inner side wall of the heat dissipation ring is fixedly connected with an annular sealing partition, and the annular sealing partition divides the heat dissipation ring into an evaporation chamber and a condensation chamber, the evaporation chamber is filled with evaporating liquid, an exhaust pipe and a return pipe are arranged in the annular sealing partition, a fixed plate is fixedly connected to the side wall of the inner ring of the annular sealing partition, and the The fixed plate is in sliding sealing connection with the annular rotating plate. The invention can cause the evaporating liquid to evaporate through the temperature change in the cabinet, drive the fan blades to rotate to dissipate heat, and the fan blades rotate to throw out the insect repellent liquid in the liquid storage tank, drive away the mosquitoes at the vents, and prevent mosquitoes from entering the power distribution cabinet cause short circuit damage to the device.
