Description

Technical Field

[0001] This invention relates to the field of display unit technology, and more particularly to a waterproof display unit. Background Technology

[0002] Wall-mounted LED displays are display devices installed on walls and are widely used in advertising, information display, stage backdrops, and other fields. Wall-mounted LED displays are mostly composed of multiple LED screens; the larger the wall-mounted LED display, the more LED screens are used. The front of each LED screen has several groups of LED beads arranged horizontally and vertically, with each group containing independently emitting R, G, and B primary color semiconductors.

[0003] Since wall-mounted LED displays are primarily used outdoors, they require high levels of waterproofing and other performance characteristics. Existing LED displays typically have a transparent panel, usually made of glass, covering the front. This panel is bonded to the LED display's housing using adhesive. Waterproofing relies on the adhesive's bonding strength, but outdoor use causes the adhesive to age rapidly, resulting in poor waterproofing. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a waterproof display unit, comprising a rectangular base shell with a plurality of LEDs arranged inside it. A front shell is fitted onto the front of the base shell, and a rubber ring is fitted onto the side wall of the base shell, with the rubber ring located between the base shell and the front shell. The front shell is made of a transparent material, and the use of the rubber ring ensures the waterproof performance of the display unit. Furthermore, the bent edges of the front shell fitted onto the side wall of the base shell lengthen the path for rainwater penetration, thus enhancing the waterproof effect to some extent.

[0005] An interface is located in the center of the back of the bottom shell, and a protective shell is fixedly connected to the outside of the interface. The interface includes a communication interface and a power supply interface, while the protective shell provides rain protection for the interface, thereby achieving a waterproof effect at the interface.

[0006] Preferably, a receiving groove is provided on the back of the bottom shell, and a handle is provided in the receiving groove. The handle is U-shaped, and its two ends are rotatably engaged in the receiving groove. The handle is designed to facilitate installation, make it easy to operate the display screen by holding the handle, and if necessary, a rope can be tied to the handle to prevent the display unit from falling.

[0007] Preferably, a stop bar is provided inside the bottom shell, and a tension spring is sleeved on the stop bar. One end of the tension spring is fixedly connected to the stop bar, and the other end is fixedly connected to the inner wall of the bottom shell. When the handle is rotated to the horizontal position, the stop bar supports the lower end of the handle. That is, under the action of the tension spring, the stop bar is kept extended into the receiving groove. The stop bar is provided so that when the handle is rotated to the maximum open position, i.e., when the handle is horizontal, it is locked in place, maintaining the position of the stop bar, which facilitates easy installation through the handle.

[0008] Preferably, a lever is slidably disposed on the back of the bottom shell, and the lever is fixedly connected to one end of the stop rod. By levering the stop rod, the stop rod is retracted into the bottom shell, thereby allowing the handle to be rotated and retracted into the receiving groove.

[0009] Preferably, a support strip is fixedly connected to the lower part of the back of the bottom shell, and threaded holes are provided on both the lower and upper parts of the back of the bottom shell. During the installation of the display unit, the support strip provides temporary support, facilitating the fixing of bolts and screws.

[0010] Preferably, a cover plate is provided on the front of the bottom shell, the cover plate covers the LED bead, and the edge of the cover plate is glued to the bottom shell. The cover plate further improves its waterproof effect.

[0011] The beneficial effects of the present invention are as follows: a front shell is provided, which is fitted onto the front end of the bottom shell, and a rubber ring is provided between the front shell and the bottom shell to ensure waterproof effect. In addition, a protective shell is provided on the back of the bottom shell, which waterproofs the inner interface. Furthermore, a cover plate fixed by adhesive is provided on the front of the bottom shell, which also serves to waterproof. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 4 As shown, a waterproof display unit includes a bottom shell 1 with a rectangular front profile. Several LED beads are arranged inside the bottom shell 1. By illuminating different colors, the display unit can display information. A front shell 5 is fitted onto the front of the bottom shell 1, and a rubber ring 7 is fitted onto the side wall of the bottom shell 1. The rubber ring 7 is used for waterproofing and is located between the bottom shell 1 and the front shell 5. The front shell 5 is made of transparent material, and its edges are vertically folded so that it fits over the front end of the bottom shell 1. This connection method increases the path length for rainwater penetration, which facilitates the installation of the sealing ring 7 and also enhances the waterproof effect to a certain extent.

[0020] An interface is provided in the middle of the back of the bottom shell 1. The interface includes a power supply interface and a communication interface. A protective shell 3 is fixedly connected to the outside of the interface. The protective shell 3 covers the interface and serves to waterproof it.

[0021] The back of the bottom shell 1 has a receiving groove, in which a handle 4 is placed. The handle 4 is U-shaped, and its two ends rotate and fit into the receiving groove. Similarly, the receiving groove is also U-shaped, and its design facilitates the placement of the handle 4. The handle 4 is provided for easy gripping and installation of the display unit.

[0022] Inside the bottom shell 1, there is a stop bar 10, which is a cylindrical rod. A tension spring 9 is sleeved on the stop bar 10. One end of the tension spring 9 is fixedly connected to the stop bar 10, and the other end is fixedly connected to the inner wall of the bottom shell 1. Under the action of the tension spring 9, the stop bar 10 is stretched into the receiving groove. When the handle 4 is rotated to the horizontal position, the stop bar 10 supports the lower end of the handle 4. That is, the stop bar 10 is set close to the rotation position of the handle 4. When the handle 4 is in use, it is pulled out of the receiving groove. When the handle 4 is rotated to the maximum value, that is, to the horizontal position, the stop bar 10 is not blocked by the handle 4 and extends into the receiving groove. At the same time, the side wall of the stop bar 10 contacts the lower end surface of the handle 4 in the horizontal position, that is, it supports the handle 4 and restricts its rotation again. This ensures that the handle 4 does not shake during use, which is not conducive to the installation and fixation of the display unit.

[0023] A lever 8 is slidably provided on the back of the bottom shell 1. The lever 8 is fixedly connected to one end of the stop lever 10. When it is necessary to retract the handle 4, slide the lever 8 to release the contact between the stop lever 10 and the handle 4, and then the handle 4 can be rotated into the receiving groove.

[0024] A support strip 2 is fixedly connected to the lower back of the bottom shell 1. The support strip 2 is a protrusion on the back of the bottom shell 1. Threaded holes are provided on the lower and upper back of the bottom shell 1. Bolts, screws and other connectors are used to fix the display unit on the corresponding support structure. The support strip 2 is provided to facilitate the display unit to be mounted on the support structure and connected with bolts and screws.

[0025] The front of the bottom shell 1 is provided with a cover plate 6, which covers the LED bead and protects it. The cover plate 6 is also made of transparent material, and the edge of the cover plate 6 is glued to the bottom shell 1 to further enhance its waterproof effect.

[0026] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
