The application discloses an explosion-proof liquid crystal display screen and relates to the technical field of explosion-proof liquid crystal display screens.The explosion-proof liquid crystal display screen comprises a base, a supporting seat fixed on the top of the base, a screen hinged on the top of the supporting seat, an outer frame fixed on the outer wall of the screen, and a square frame slidingly connected to the inner wall of the outer frame.When the square frame is impacted from the front side, the square frame moves towards the outer frame, and the compression of the return spring drives the square frame to move the transmission rod, further drives the L-shaped plate and the large limiting rod to move away from the outer frame.When the large limiting rod is separated from the rotating rod, the rotating rod and the protection plate are rotated under the return action of the large torsional spring, so that the protection plate is counterclockwise rotated to be parallel to the screen.When the screen is impacted from the front side and is tilted backward, the protection plate shields the screen to prevent sparks caused by secondary damage.

The utility model discloses a good wear resistance's PE water supply pipe relates to PE water supply pipe technical field. Including the water pipe main part, the right side end of water pipe main part is inserted with the connecting sleeve, and the connecting sleeve is fixed between the connection of locking mechanism and water pipe main part, and the locking mechanism includes the limiting ring and the thread cover, and the inner wall of water pipe main part is provided with first protection mechanism, and first protection mechanism includes first elastic coating, antistatic coating and bacteriostatic coating, and the outer surface of water pipe main part is provided with second protection mechanism, and second protection mechanism includes second elastic coating, temperature insulation coating, fire -retardant coating and wear -resisting coating. The utility model increases the elasticity and wear resistance of water pipe main part inner and outer side wall, makes water pipe main part have better wear resistance, makes it not easy to be damaged when being washed and rubbed, prolongs the life, and simultaneously, the connection between adjacent water pipe main part is more compact, and the protection function of water pipe main part end is increased, makes the connection more stable and firm.
