Description

Technical Field

[0001] This utility model belongs to the field of waterproof technology, and in particular relates to a waterproof structure for an outdoor LED display screen and the display screen thereof. Background Technology

[0002] Current outdoor LED displays are assembled by using magnets on the back of the modules to hold them in place with the screw heads of the housing. The module's signal terminals are then plugged into the housing's signal ports. A rubber ring is used to seal the contact surface between the module's bottom shell and the housing for waterproofing. However, this rubber ring sealing method has poor waterproofing. If the module is not properly assembled, or if the magnets are not sufficiently magnetic, the display can deform under heat during outdoor use. This can cause gaps between the rubber ring and the housing, leading to water leakage during rain, product defects, increased maintenance costs, reduced product lifespan, and even risks such as short circuits.

[0035] Reference Figure 1-13 As shown, an outdoor LED display waterproof structure includes a sealing ring 1 and a buckle 2. The sealing ring 1 has an inner flange 11 at its upper end and an "n"-shaped groove 12 between the inner flange 11 and the inner wall of the sealing ring 1. The sealing ring 1 has an outer flange 13 at its lower end. The buckle 2 has a pressure plate 21 and a hook 22. The pressure plate 21 has a through hole 23 at its center corresponding to the sealing ring 1. The hooks 22 are symmetrically arranged on the through hole 23 of the pressure plate 21, and the hooks 22 are arranged facing outwards.

[0036] The inner flange 11 and outer flange 13 of the sealing ring 1 work together to achieve a sealed seal at the connection. The snap fastener 2 ensures that the sealing ring 1 is tightly connected to the connector, so as to fix the sealing ring 1 to prevent it from shaking or deforming, thereby improving the sealing degree and more effectively preventing failure when the connector is deformed.

[0037] Furthermore, the cross-section of the sealing ring 1 is racetrack shaped.

[0038] The shape of the sealing ring 1 corresponds to the opening of the sealing element and can be square, round, or other shapes.

[0039] Furthermore, the upper end face of the sealing ring 1 is provided with at least one annular protrusion 14.

[0040] The annular rib 14 can improve the tightness between the pressure plate 21 and the annular rib 14.

[0041] Furthermore, the lower end face of the sealing ring 1 is provided with a groove 15; the outer side of the sealing ring 1 is provided with a plurality of sealing rings 16.

[0042] The groove 15 facilitates the fit between the sealing ring 1 and the surface of the sealing element; the sealing ring 16 facilitates the fitting of the sealing element into the sealing ring 1 and ensures a tight fit.

[0043] Furthermore, a downwardly extending limiting plate 24 is provided at the through hole 23.

[0044] The limiting plate 24 restricts the inner flange 11 of the "n"-shaped groove 12.

[0045] Furthermore, the maximum size of the pressure plate 21 does not exceed the maximum size of the inner flange 11. Preferably, the maximum size of the pressure plate 21 is the same as the maximum size of the upper end of the sealing ring 1.

[0046] Furthermore, the maximum size of the pressure plate 21 is larger than the maximum size of the upper end of the sealing ring 1, such as... Figure 3 , 7 As shown in 11 and 13.

[0047] An outdoor display screen includes a module 3 and a housing 4, wherein the waterproof structure described above is provided between the signal holes 5 of the module 3 and the housing 4.

[0048] Furthermore, combined Figure 1 , 2 As shown in Figures 4, 5, 6, 8, 9, 10, and 12, the sealing ring 1 of the waterproof structure is fitted onto the signal hole 5 on the back of the bottom shell of the module 3. The ear 51 of the signal hole 5 is embedded in the "n"-shaped groove 12. The lower end of the sealing ring 1 is in contact with the back of the bottom shell of the module 3. The signal hole 5 of the housing 4 is fitted onto the sealing ring 1 and presses against the outer flange 13. The pressure plate 21 of the snap fastener 2 is pressed against the upper end face of the sealing ring 1, and the hook 22 is engaged with the hook 22 on the front of the bottom shell of the module 3.

[0049] During assembly: ① A sealing ring 1 is installed at the signal hole 5 on the back of the bottom shell of module 3; ② The "n"-shaped groove 12 of the sealing ring 1 is inserted into the ear 51 of the signal hole 5 on the bottom shell of module 3, and the lower end face of the sealing ring 1 is in contact with the bottom shell of module 3; ③ The pressure plate 21 of the snap fastener 2 presses down on the upper end face of the sealing ring 1, and two hooks 22 are provided at the bottom; ④ During installation, first insert the sealing ring 1 into the ear 51 on the back of the bottom shell, so that the ear 51 covers the sealing ring 1 inside and out; insert the snap fastener 2 into the signal hole 5 on the back of module 3, the two hooks 22 are locked into the inner surface of the bottom shell, and the pressure plate 21 presses down on the sealing ring 1 to fix the sealing ring 1 so as not to shake or deform; ⑤ Install module 3 into the box 4, and the sealing ring 16 on the side of the sealing ring 1 is tightly fitted and sealed with the inner wall of the signal hole 5 of the box 4 to achieve waterproof function.

[0050] Furthermore, combined Figure 3 , 4 As shown in 5, 7, 8, 9, 11, and 13, the pressure plate 21 of the buckle 2 is pressed against the upper end face of the sealing ring 1 and the edge of the signal hole 5 of the housing 4.

[0051] During assembly: ① A sealing ring 1 is installed at the position of the signal hole 5 on the back of the bottom shell of module 3; ② The "n"-shaped groove 12 of the sealing ring 1 is inserted into the ear 51 of the signal hole 5 on the bottom shell of module 3, and the lower end face of the sealing ring 1 is in contact with the bottom shell of module 3; ③ The pressure plate 21 of the snap fastener 2 presses down on the upper end face of the sealing ring 1, and two hooks 22 are provided at the bottom; ④ The surface of the pressure plate 21 presses down on the upper end of the sealing ring 1, and the width of the surface of the pressure plate 21 is greater than the step width of the signal hole 5 of the frame of the housing 4, so that the pressure plate 21 can press down on the housing 4 at the same time; ⑤ During installation, first insert the sealing ring 1. The ears 51 on the back of the bottom shell are fitted with the sealing ring 1 both inside and out. The module 3 with the sealing ring 1 fitted is installed into the housing 4, and the signal holes 5 are inserted. Then, the buckle 2 is inserted into the module 3 through the signal hole 5 on the back of the housing 4. The two hooks 22 are locked into the inner surface of the bottom shell, and the surface of the pressure plate 21 presses the sealing ring 1 to fix the sealing ring 1 so that it does not shake or deform. At the same time, the widened surface of the buckle 2 contacts the stepped surface of the housing 4 frame, so that the module 3 and the housing 4 frame are tightened together, improving the sealing degree and more effectively preventing the module 3 from failing when it is deformed.
