n first sealing rings 910 are uniformly arranged at intervals along the axial direction of the bolt 8, and the first sealing rings 910 are sleeved on the outer side of the bolt 8;
N+1 second seal rings 920 are uniformly arranged at intervals along the axial direction of the bolt 8, and the second seal rings 920 are sleeved on the outer side of the first seal ring 910;
N third seal rings 930 are uniformly arranged at intervals along the axial direction of the bolt 8, and the third seal rings 930 are sleeved on the outer side of the second seal ring 920;
Wherein n is 3 or more;
Of the plurality of second seal rings 920, the section of the second seal ring 920 contacting the bottom surface of the first connecting column 6 and the section of the second seal ring 920 contacting the bottom surface of the insertion hole 710 are both trapezoidal, and the sections of the remaining second seal rings 920 are hexagonal;
The surface of the first sealing ring 910 contacting the second sealing ring 920 is a first convex slope formed by two first slopes 911, and the surface of the third sealing ring 930 contacting the second sealing ring 920 is a second convex slope formed by two second slopes 931.
The third sealing element 9 ensures the sealing performance of the connection of the bolts 8 and the connection supporting capacity of the first connecting column 6 and the second connecting column 7, and on the premise that the bottom shell 1 has stronger supporting capacity, the first connecting column 6 and the second connecting column 7 play a main supporting role, and the first connecting column 6 and the second connecting column 7 break when being stressed too much;
Therefore, the third seal 9 is provided as a multi-layer supporting seal structure, and due to the special structure of the three-layer seal ring, when the lock bolt 8 or the mask 2 is stressed above, the second seal ring 920 with the trapezoid cross section in contact with the first connecting post 6 and the second seal ring 920 with the trapezoid cross section in contact with the insertion hole 710 are subjected to extrusion, under the contact action of the first convex inclined surface and the second convex inclined surface with the second seal ring 920, the first seal ring 910 and the third seal ring 930 in contact with the second seal ring 920 are extruded, and then all the second seal ring 920, the first seal ring 910 and the third seal ring 930 in contact in sequence are extruded, the first seal ring 910 forms a sealing abutting action on the outer peripheral surface of the bolt 8, the third seal ring 930 forms a sealing abutting action on the inner peripheral surface of the insertion hole 710, and the second seal ring 920 forms a sealing abutting action with the first seal ring 910 and the third seal ring 930, so that a multi-layer seal is formed in the axial direction;
In addition, the multi-layer seal also plays a role in elastic support for the connection of the first connecting column 6 and the second connecting column 7, when the mask 2 is stressed, acting force sequentially acts on the multi-layer sealing ring, and the elastic support force can be formed by playing a role in damping under the elastic recovery acting force of the sealing ring, so that the first connecting column 6 and the second connecting column 7 are in non-rigid connection, and breakage caused by overlarge stress is prevented; moreover, the levelness of the connection of the mask 2 can be ensured, so that the stress uniformity of the mask 2 is improved, the mask 2 is prevented from being damaged due to uneven stress, and meanwhile, the third sealing piece 9 can also have an anti-loosening effect on the installation of the bolt 8; the third sealing member 9 is installed inside the bottom shell 1 and is not exposed to the external environment, so that the service life of the third sealing member can be further prolonged.
As shown in fig. 12, further, a first elastic supporting cavity 940 is formed between the first protruding inclined surface, the second protruding inclined surface, and the opposite sides of the two adjacent second sealing rings 920;
a second elastic supporting cavity 950 is formed between the outer circumferential surface of the bolt 8, the inner circumferential surface of the second sealing ring 920 and the opposite side surfaces of the two adjacent first sealing rings 910;
The outer ring surface of the second seal ring 920, the inner peripheral surface of the insertion hole 710, and the opposite sides of the adjacent two third seal rings 930 form a third elastic supporting cavity 960 therebetween.
Because the first sealing ring 910, the second sealing ring 920 and the third sealing ring 930 are all arranged at intervals in the axial direction, the first elastic supporting cavity 940, the second elastic supporting cavity 950 and the third elastic supporting cavity 960 can be formed, and the three elastic supporting cavities are all sealing cavities after being installed, so that the sealing device also has elastic capability, and can further improve the supporting performance of the third sealing piece 9 and the supporting capability.
In addition, the cavity formed among the bottom surface of the jack 710, the first sealing ring 910 at the bottom end and the second sealing ring 920 at the bottom end is a drainage cavity, because the bolt 8 is not sealed with the second through hole formed in the bottom surface of the jack 710, if water is permeated from the bottom of the bottom shell 1, the water will enter the cavity first, the first sealing ring 910 is sealed with the bolt 8, the second sealing ring 920 is sealed with the bottom surface of the jack 710, and the first sealing ring 910 is also sealed with the second sealing ring 920, so that the cavity is compressed and the air pressure is increased as long as the third sealing member 9 is extruded after the mask 2 is stressed, so that the water entering the cavity is discharged, and the waterproof performance is further improved.
As shown in fig. 13, a process for producing an LED floor tile interactive screen with a waterproof function includes:
the manufactured LED lamp panel 3 is placed into a container 13 containing nano waterproof liquid for soaking, and after the soaking is finished, the LED lamp panel 3, the mask 2 and the bottom shell 1 are assembled in a sealing way;
The nano waterproof liquid level is higher than that of the nozzle 14, a water pump 15 is arranged outside the container 13, the water pump 15 can pump the nano waterproof liquid in the container 13 to the nozzle 14, and jet flow formed by the nozzle 14 can disturb the nano waterproof liquid.
In order to ensure the waterproof performance of the LED floor tile interactive screen, the manufactured LED lamp panel 3 is soaked by adopting the nano waterproof liquid, so that the waterproof, dampproof and anti-corrosion performances of the LED lamp panel 3 can be improved;
In order to improve the soaking speed and the soaking effect, a nozzle 14 is arranged on at least one side of the container 13, a water suction pump 15 sucks nano waterproof liquid from the bottom of the container 13 to the nozzle 14, then jet flow is formed by the nozzle 14 to form disturbance on the nano waterproof liquid so as to enable the nano waterproof liquid to circularly flow, the liquid level of the nano waterproof liquid is higher than that of the nozzle 14, the purpose of the arrangement is to prevent the nano waterproof liquid from being attached to the LED lamp panel 3 due to the fact that the jet flow and air are mixed to form bubbles, in addition, when the LED lamp panel 3 is placed in the nano waterproof liquid, a small amount of bubbles are generated on the surface of the LED lamp panel 3, if the bubbles exist all the time, the nano waterproof liquid is difficult to attach to the position, and therefore the waterproof performance is affected; jet flow generated by the nozzle 14 is sprayed towards the LED lamp panel 3 in a high-pressure divergent mode, bubbles on the surface of the LED lamp panel 3 can be broken rapidly, so that the nano waterproof liquid can be quickly and comprehensively attached to the LED lamp panel 3, the soaking efficiency and the attaching quality are improved, and the waterproof performance of the LED lamp panel 3 is further improved.
