Description

Technical Field

[0001] This utility model relates to the field of wireless communication equipment technology, and in particular to a novel sealing component. Background Technology

[0002] Common sealing methods include gasket seals, packing seals, mechanical seals, and non-contact seals. A mechanical seal is a device that prevents fluid leakage by having at least one pair of end faces perpendicular to the axis of rotation kept in contact and sliding relative to each other under the action of fluid pressure, the elastic or magnetic force of the compensation mechanism, and the cooperation of auxiliary seals.

[0003] Mechanical seals are mainly composed of a dynamic ring, a stationary ring, auxiliary seals, clamping components, and transmission components. The auxiliary seals mainly use sealing rings, which have excellent resistance to corrosion, tearing, compression deformation, ozone, sunlight, and weathering.

[0004] The seal has the following defects: after three to five years of long-term use, it may lose its elasticity due to aging, which may lead to cracking or expansion and leakage, and thus cause the seal to fail. Therefore, a new type of seal is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of sealing component, which aims to improve the problem that the existing technology may lose elasticity due to aging after three to five years of long-term use, resulting in easy cracking or expansion and leakage of the sealing component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel sealing element, comprising a sealing element body, a front end connector fixedly connected to the front inner wall of the sealing element body, a rear end connector fixedly connected to the rear inner wall of the sealing element body, an adjustment mechanism provided on the sealing element body, an auxiliary mechanism provided on the adjustment mechanism, the adjustment mechanism including a mating groove, the mating groove being formed on the rear inner wall of the sealing element body, a threaded groove being formed on the rear inner wall of the mating groove, a secondary groove being formed on the front inner wall of the sealing element body, a first mounting plate being threadedly connected to the inner wall of the threaded groove, a first sealing ring being fitted and connected to the rear outer wall of the first mounting plate, a second mounting plate being threadedly connected to the inner wall of the front of the secondary groove, and a second sealing ring being fixedly connected to the front and rear outer walls of the second mounting plate.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a directional mark, which is opened on the rear outer wall of the first sealing ring, and a groove is opened on the side outer wall of the sealing body.

[0008] As a further description of the above technical solution: there are two first sealing rings, and the two first sealing rings are respectively attached to the front and rear outer walls of the first mounting plate.

[0009] As a further description of the above technical solution: the thickness of the first sealing ring and the second sealing ring is five millimeters, the first sealing ring is attached to the rear outer wall of the sealing body, and the second sealing ring is attached to the front outer wall of the sealing body.

[0010] As a further description of the above technical solution: a reflective strip is fixedly connected to the outer side wall of the directional sign.

[0011] As a further description of the above technical solution: the groove is annularly formed on the outer side wall of the sealing body, and a frosted pad is fixedly connected to the outer side wall of the groove.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the front connector and rear connector, together with the adjustment mechanism, have a docking groove and threaded groove structure design to achieve a stable connection between the wireless antenna electronic components and the extended signal plug. With the help of double sealing rings, a multi-layer sealing protection is formed. At the same time, hydrogenated nitrile rubber material is used, which takes advantage of its excellent ozone resistance, high and low temperature resistance and fatigue resistance to significantly enhance the durability of the seal in complex environments, effectively prevent water, dust and other impurities from entering, and ensure the stability of antenna signal transmission.

[0013] 2. In this utility model, the threaded connection design of the first mounting plate, the second mounting plate and the threaded groove and the auxiliary groove in the adjustment mechanism allows the sealing ring to be disassembled and replaced independently, avoiding the need to replace the entire sealing component and greatly reducing maintenance costs; the design of the directional mark, reflective strip and frosted groove of the auxiliary mechanism not only provides directional guidance for installation, but also optimizes the operation process and improves installation efficiency and accuracy by improving grip comfort and friction.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a novel sealing element, comprising a sealing element body 1. A front connector 2 is fixedly connected to the inner wall of the front side of the sealing element body 1. The front connector 2 is used to connect with the electronic component end of a wireless antenna, providing a stable connection and ensuring a signal transmission path. A rear connector 3 is fixedly connected to the inner wall of the rear side of the sealing element body 1. The rear connector 3 is used to connect with the extended signal plug of the wireless antenna, providing an interface for signal extension. An adjustment mechanism 4 is provided on the sealing element body 1, and an auxiliary mechanism 5 is provided on the adjustment mechanism 4. The adjustment mechanism 4 includes a docking groove 41, which is used to accommodate the component corresponding to the rear connector 3, making the connection structure more compact and enhancing connection stability. The docking groove 41 is formed in the sealing element. The rear inner wall of the main body 1 has a threaded groove 42, and the front inner wall of the sealing body 1 has a secondary groove 422. The inner side wall of the threaded groove 42 is threadedly connected to the first mounting plate 43. The threaded groove 42 and the first mounting plate 43 cooperate to realize the detachable installation of the first mounting plate 43, which facilitates the subsequent replacement and maintenance of the first sealing ring 44. The rear outer wall of the first mounting plate 43 is fitted with the first sealing ring 44. The first sealing ring 44 is used to seal the connection between the wireless antenna extension signal plug and the rear connector 3 to prevent external water, dust, impurities, etc. from entering and affecting the antenna performance. The front inner wall of the secondary groove 422 is threadedly connected to the second mounting plate 45. The front and rear outer walls of the second mounting plate 45 are fixedly connected to the second sealing ring 46.

[0018] Reference Figures 1-3There are two first sealing rings 44, which are respectively attached to the front and rear outer walls of the first mounting plate 43. The thickness of the first sealing ring 44 and the second sealing ring 46 is five millimeters. The first sealing ring 44 is attached to the rear outer wall of the sealing body 1, and the second sealing ring 46 is attached to the front outer wall of the sealing body 1. The material of the first sealing ring 44 and the second sealing ring 46 is hydrogenated nitrile butadiene rubber (HNBR). After hydrogenation, the molecular chain saturation of this material is as high as 95%, which almost eliminates the double bond structure and significantly reduces ozone (O2). 3) Risk of cracking due to corrosion: Ordinary NBR can only withstand a few hours in a 50pphm ozone environment, while HNBR can withstand hundreds of hours, and its long-term operating temperature range is widened to -30℃~150℃ (some high hydrogenation grades can reach 170℃), which is more than 50℃ higher than NBR (-20℃~100℃). Moreover, it is not easy to harden and become brittle due to oxidation and cross-linking at high temperatures. At the same time, its dynamic fatigue life in long-term use is 2~3 times higher than that of NBR, making it suitable for high-frequency vibration environments (such as aerospace equipment and industrial mechanical seals), reducing cracks caused by repeated deformation.

[0019] Reference Figures 1-3 The auxiliary mechanism 5 includes a directional indicator 51, which is located on the outer rear wall of the first sealing ring 44. The directional indicator 51 provides the operator with installation direction guidance, avoiding the impact of incorrect installation direction on sealing effect and connection stability. A groove 52 is provided on the outer side wall of the sealing body 1. A reflective strip is fixedly connected to the outer side wall of the directional indicator 51. The reflective strip can reflect light in low light conditions, making the directional indicator 51 more conspicuous and facilitating the operator to accurately identify the installation direction in dim environments. The groove 52 is circumferentially located on the outer side wall of the sealing body 1. The circumferential groove 52 ensures that the operator can obtain good friction regardless of the angle from which they hold the sealing body 1, improving operational convenience. A frosted pad is fixedly connected to the outer side wall of the groove 52. The frosted pad further increases the friction of the groove 52, preventing the sealing body 1 from slipping from the hand during operation and increasing grip comfort.

[0020] Working principle: Personnel follow the directional indication of the directional sign 51, then grip the groove 52 with their hands, and rotate the sealing body 1 to thread the electronic component end of the wireless antenna to the front connector 2. This ensures that the second sealing ring 46 on the second mounting plate 45 of the front connector 2 is tightly attached to the connection point for sealing. The extended signal plug of the wireless antenna is then threaded to the rear connector 3, ensuring that the first sealing ring 44 on the first mounting plate 43 is tightly attached to the bottom of the plug for sealing. After several years of use, the sealing body 1 is separated from the connectors at both ends of the wireless antenna. The first mounting plate 43 is then rotated to separate from the threaded groove 42, and the first sealing ring 44 is replaced individually to reduce the high cost of replacing the entire sealing body 1. Then, the second mounting plate 45 is rotated to separate from the secondary groove 422, and the second sealing ring 46 is replaced individually.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
