[0020] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0021] See attached Figure 1 As shown, in this embodiment, a universal waterproof structure includes a first plug-in portion 1 and a second plug-in portion 2 that are relatively plugged in and matched, wherein the first plug-in portion 1 and the second plug-in portion 2 can be used in a variety of assembly structures, such as referring to the attached Figure 3 The vibrator box 100 shown in the figure, and the Figure 7 The outdoor omnidirectional TV antenna shown is often used in outdoor environments, and has high requirements for the waterproof performance of the joints to prevent water vapor from penetrating into the product from the joints.

[0022] See attached Figure 1 and 2 As shown, in this embodiment, the first plug-in portion 1 is formed with an insert block 11, wherein the outer edge of the end face of the insert block 11 is sleeved with a main sealing ring 3, and the inner circumferential surface, outer circumferential surface and two ring end faces of the main sealing ring 3 are all formed with annular collapse grooves 31, and each annular collapse groove 31 is located at the midline position of the surface. The structural design of the annular collapse groove 31 is adopted. When the main sealing ring 3 is squeezed by an external force in any direction, the space formed by the annular collapse groove 31 is utilized to enable the main sealing ring 3 to collapse and deform toward the annular collapse groove 31, which not only facilitates the installation of the main sealing ring 3, but also the main sealing ring 3 can be pressed and fit the splicing position after being compressed, especially suitable for splicing positions with interference fit.

[0023] Further, the main sealing ring 3 is as shown in the attached Figure 2 The structure shown is a ring structure before installation. Because it has certain stretching properties, it can adapt to the insert block 11 structures of different shapes, which is not specifically limited here.

[0024] In this embodiment, the second plug-in portion 2 is formed with a slot 21 for interference fit with the plug-in block 11, that is, the size of the plug-in block 11 is equal to or slightly larger than the size of the slot 21, so that when the first plug-in portion 1 and the second plug-in portion 2 are relatively plugged in, there is an interference fit between the plug-in block 11 and the slot 21, thereby eliminating the gap between the two as much as possible, effectively preventing water vapor from penetrating into the product through the gap.

[0025] Therefore, when the main seal ring 3 is inserted into the slot 21 along with the plug block 11, the main seal ring 3 is compressed and deformed by the interference squeeze of the inner wall of the slot 21 and the plug block 11. Specifically, the main seal ring 3 is compressed and deformed during the insertion process. Since the main seal ring 3 has multiple annular collapse grooves 31, it is compressed and deformed by the multi-directional squeeze of the slot 21 and the plug block 11, so that the plug block 11 can be smoothly inserted into the slot 21 relative to the slot 21, avoiding abnormal problems such as the main seal ring 3 being stuck during the insertion process. In addition, after the plug block 11 is inserted into the slot 21 relative to the slot 21, the plug block 11 and the slot 21 will squeeze the main seal ring 3 to make it press and fit the gap between the end of the plug block 11 and the inner bottom surface of the slot 21. Therefore, not only the interference fit between the plug block 11 and the slot 21 and the compression and fitting effect of the main sealing ring 3 effectively eliminate the gap between the plug block 11 and the slot 21, but also it is ensured that no water vapor will penetrate into the interior of the product from the gap, thereby achieving the IPX4 waterproof level.

[0026] Furthermore, a stepped groove is formed on the outer edge of the end face of the plug block 11 for the main sealing ring 3 to be mounted, wherein the depth of the stepped groove is less than the radial thickness of the main sealing ring 3 and the height of the stepped groove is less than the axial thickness of the main sealing ring 3. Therefore, through the structural design of the stepped groove, when the main sealing ring 3 is mounted on the plug block 11, the main sealing ring 3 partially protrudes from the end face and the outer peripheral surface of the plug block 11, thereby ensuring that the main sealing ring 3 can still fit the inner wall of the slot 21 after being compressed and deformed.

[0027] In order to facilitate the understanding of the above-mentioned universal waterproof structure, further explanation is given below in combination with specific implementation methods.

[0028] Implementation method 1: See attached Figure 3-6As shown, the two antennas need to be plugged into the vibrator box 100 respectively, and the joints between the antenna and the vibrator box 100 need to be waterproofed. Based on this, each antenna at this time is inserted into the first plug-in portion 1 as a rod body 200 (that is, one rod body 200 is fixedly inserted into one first plug-in portion 1), so that one end of the rod body 200 extends through the end surface of the plug block 11 of the first plug-in portion 1, and the vibrator box 100 is formed with two slots for the two rod bodies 200 and the first plug-in portion 1 to be plugged in and out (that is, each slot corresponds to the slot 21 of the second plug-in portion 2), and the inner bottom surface of the slot 21 of the second plug-in portion 2 (equivalent to the vibrator box 100) is formed with a plurality of slots. A functional groove is formed on the rod body 200 end portion for engagement with, whereby when the rod body 200 (equivalent to the antenna) is plugged into the slot 21 (equivalent to the slot of the vibrator box 100) of the second plug-in portion 2 along with the plug-in block 11 of the first plug-in portion 1, the rod body 200 will also be plugged into the functional groove, and with the help of the relative plug-in fit between the second plug-in portion 2 and the sealing effect of the main sealing ring 3, the joint between the rod body 200 and the vibrator box 100 is ensured to be better sealed, thereby effectively playing a waterproof role.

[0029] Implementation method 2: See attached Figure 7-11 As shown, the V-band component with the antenna needs to be plugged into the outdoor omnidirectional TV antenna base 300, and the joint between the antenna and the outdoor omnidirectional TV antenna base 300 needs to be waterproofed. Based on this, the antenna at this time is correspondingly arranged on the second plug-in part 2 as the rod body 200 (that is, the bottom of the shell of the V-frequency component is correspondingly formed with the second plug-in part 2 and the slot 21), so that one end of the rod body 200 extends through the inner bottom surface of the slot 21 of the second plug-in part 2, and the outdoor omni-directional TV antenna seat 300 is formed with a first plug-in part 1 for the rod body 200 and the second plug-in part 2 to be plugged in and matched, and the end surface of the plug-in block 11 of the first plug-in part 1 is formed with a functional groove for the end of the rod body 200 to be embedded. Therefore, when the rod body 200 (equivalent to the antenna) is relatively plugged into the plug-in block 11 of the first plug-in part 1 along with the slot 21 of the second plug-in part 2, the rod body 200 will also be plugged into the functional groove, and with the help of the relative plug-in fit between the second plug-in part 2 and the sealing effect of the main sealing ring 3, it is ensured that the splicing position between the rod body 200 and the outdoor omni-directional TV antenna seat 300 is better sealed, and effectively plays a waterproof role.

[0030] In summary, both the first and second embodiments can achieve effective waterproofing effects, have certain versatility, and can effectively prevent water vapor from penetrating to ensure the sealing of the joints. This universal waterproof structure can be applied not only to the joints between the antenna and the vibrator box 100, but also to the joints between the antenna and the outdoor omnidirectional TV antenna base 300, and has broad application prospects.

[0031] Furthermore, in the first embodiment, in order to further improve the waterproof performance, the first plug-in part 1 is further formed with a stopper 12 arranged around the outer periphery of the rear end of the plug-in block 11, and the second plug-in part 2 is further formed with a step groove arranged around the slot 21 and used for the stopper 12 to be embedded; in addition, a secondary sealing ring 121 is arranged between the stopper 12 and the step groove (the secondary sealing ring 121 is sleeved around the outer periphery of the stopper 12). Thus, the secondary sealing ring 121 is used to seal the embedded stopper 12 and the step groove, thereby preventing external water vapor from penetrating from the gap between the stopper 12 and the step groove, further improving the waterproof effect.

[0032] In short, this universal waterproof structure has the advantages of excellent waterproof performance, simple structure, and strong versatility, and provides a reliable solution for waterproofing of outdoor equipment at the joints.
