Referring to fig. 1-6, the present embodiment provides a display for displaying images, in particular, a medical display used in an operating room, the display of the present invention includes a display screen, a housing 2, a transparent cover plate 3 and a sealing ring 1.
The display screen is a rectangular liquid crystal screen, and the upper surface of the display screen is used for displaying images. The casing 2 is wrapped on the periphery of the display screen, and a groove 21 is formed inside the casing 2.
In order to protect the display screen from being damaged, a layer of light-transmitting cover plate 3 needs to be attached to the outer side of the liquid crystal panel, so that the effects of preventing water and dust and preventing the display screen from being scratched are achieved. The light-transmitting plate of this embodiment adopts the glass apron of glass material in order to improve the printing opacity effect, and then improves the image quality display effect, and printing opacity apron 3 sets up in the top of casing 2 and display screen.
The sealing ring 1 is arranged around the edge of the inside of the shell 2 and correspondingly arranged in the groove 21, the upper surface 12 of the sealing ring 1 is in contact with the lower surface 13 of the light-transmitting cover plate 3, the lower surface 13 of the sealing ring 1 is in contact with the bottom surface of the groove 21, the side surface of the sealing ring 1 is provided with a continuous protruding portion 11, and the groove 21 is provided with a recessed portion 211 matched with the protruding portion 11.
From this, be provided with sealing washer 1 between printing opacity apron 3 and casing 2, sealing washer 1 can compression deformation, and the side of sealing washer 1 is provided with continuous bellying 11 to realize the multiple spot contact cooperation with the casing, and then promote waterproof, dustproof and prevent the effect of alcohol.
The material of the sealing ring 1 in the embodiment is silicon rubber which has good water resistance, alcohol resistance and ozone resistance, so that the medical display can be conveniently wiped by alcohol.
The utility model discloses in other embodiments, nitrile rubber is chooseed for use to the material of sealing washer 1, practices thrift the cost when playing waterproof dirt-proof.
In this embodiment, the bellying 11 of sealing washer 1 side encircles sealing washer 1 and forms continuous chimb, and the side includes medial surface and lateral surface, and medial surface and lateral surface all are provided with this continuous chimb, and recess 21 is provided with the depressed part 211 with bellying 11 adaptations. After the sealing ring 1 is assembled in the groove 21, the continuous convex part 11 is matched with the concave part 211, so that the sealing ring 1 is ensured not to be easily separated from the groove 21. The utility model discloses need not just can prevent that sealing washer 1 from droing at sealing washer 1 gum. Secondly, water, dust and alcohol cannot pass through the matching part of the convex part 11 and the concave part 211, so that the water, dust and alcohol cannot reach the inside of the display to play the roles of water and dust prevention and alcohol.
Further, the upper surface 12 of sealing washer 1 contacts with the lower surface 13 of printing opacity apron 3, and the lower surface 13 of sealing washer 1 contacts with the bottom surface of recess 21, and the upper surface 12 of sealing washer 1 all sets up to outer drum arcwall face with lower surface 13 to upper surface 12 and lower surface 13 shrink when avoiding making and sink, thereby avoid causing and contact surface contact failure, avoid reducing the protecting effect.
