This utility model discloses a full-color LED large-screen display device, relating to the field of LED large screens. It includes an outer frame, with a display screen mounted on the front side of the frame. A mesh is installed at the bottom of the through-space of the outer frame, and a motor is installed above the mesh. A fan is connected to the output end of the motor. Air ducts are symmetrically arranged inside the outer frame, with air holes evenly spaced on both sides of the ducts. Heat-absorbing blocks are evenly spaced through the left and right sides of the outer frame, with through holes in the center of each block. Heat dissipation fins for auxiliary heat dissipation are evenly spaced on the back of the outer frame. During use, this full-color LED large-screen display device can evenly deliver air into the interior space of the large screen, and the internal heat is carried out to the outside through even airflow. Simultaneously, the heat-absorbing and guiding elements on the sides and the heat-absorbing and heat-dissipating components on the back can accelerate heat dissipation, thereby improving heat dissipation efficiency, extending the lifespan of the large screen, and preventing heat damage.

The utility model belongs to the technical field of solar water heaters, and particularly relates to a solar vacuum tube and a solar water heater. The solar vacuum tube comprises a vacuum tube body and a flow guide part, the flow guide part is arranged in the vacuum tube body, and a flowing channel is formed between the flow guide part and the inner wall of the vacuum tube body and used for fluid flowing. According to the solar vacuum tube provided by the invention, the flowing space of the fluid in the vacuum tube body is optimized, the circulating speed of the fluid in the vacuum tube body is increased, heat loss is reduced, and the heat gain of the solar vacuum tube is higher.

The utility model relates to the field of part connection, in particular to a plastic part clamping structure which comprises a buckle body of a front cover and a buckling position structure correspondingly matched with the buckle body and located on a rear cover extension plate, and a through hole is formed in the rear cover extension plate in a penetrating mode to form a buckling position part base body. The inner wall, close to the rear cover extension plate, of the buckling part base body extends and is provided with a flow rate expansion part penetrating through a through hole in a protruding mode, the upper surfaces of the buckling part base body and the flow rate expansion part extend and are provided with buckling guide parts in a protruding mode, the inner wall, close to the rear cover extension plate, of the buckling guide parts is an inclined guide plane, and the width of the flow rate expansion part is 1 / 2-1 of the width of the buckling part base body. The joint between the buckling position guide part and the buckling position part base body and the joint between the buckling position guide part and the flow velocity expansion part are chamfers, and the buckling position guide part, the buckling position part base body and the flow velocity expansion part are integrally formed to form a The structure can effectively prevent poor glue leakage at the buckle position in the production process of the plastic rear shell, avoids the dark crack defect, enhances the structural strength of the buckle position, and prolongs the service life of the product.

The utility model discloses a power control module, which comprises a power control module main body, and the power control module main body is rotatably connected with a height adjusting assembly used for adjusting the height of the power control module main body. The height adjusting assembly comprises a first connecting rod, a rotating block and a second connecting rod, a first clamping groove is formed in the power control module body, the rotating block is connected into the first clamping groove through a shaft, the rotating block is fixedly connected to one end of the first connecting rod, the first connecting rod is a cylinder, and the second connecting rod is slidably connected into the first connecting rod; and the second connecting rod is filled with paraffin. Compared with the prior art, the power control module is convenient for adjusting the gap between the lower end face of the power control module and the placement surface according to actual conditions, thereby increasing the air flowing space of the lower end face of the power control module, facilitating heat dissipation, and reducing the condition that the service life of the power control module is influenced by high temperature of the power control module.

This application provides an isolation protective headgear, including a headgear and a protective end piece integrally formed with the headgear. The headgear comprises a double-layer headgear formed by an inner protective layer and an outer protective layer, with a support frame disposed between the inner and outer protective layers, the support frame being disposed on the inner protective layer. A support airbag is disposed through the inner wall of the outer protective layer. This utility model, by adding a support airbag and a support frame that works in conjunction with the support airbag, effectively prevents the support frame from collapsing and conforming to the face due to sweat or deformation caused by movement, enhancing airflow space and improving comfort. Furthermore, the support frame, made of lightweight materials and hollow in design, significantly reduces weight, effectively preventing headaches or skin pressure injuries caused by a heavy support frame.
