However, existing protective structures still have shortcomings in terms of sealing, allowing moisture to easily penetrate the interior. Over time, this can lead to corrosion or damage to internal components, affecting the antenna's lifespan. Furthermore, the cables between the antenna and the mounting post are usually exposed, lacking effective protection. They are not only susceptible to mechanical damage and environmental corrosion but may also affect signal transmission quality. Utility Model Content

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment provides a communication antenna protection device, such as... Figures 1-4 As shown, the communication antenna protection device includes a column assembly 1, a protective cover 2, a mounting plate assembly 3, a variable diameter positioning cylinder 4, a first sealing ring 5, and a telescopic conduit 6. The column assembly 1 includes a column body 11 and a connecting hole seat 12. The column body 11 has a vertically extending inner cavity 111, and its side wall has a first connecting hole 112 communicating with the inner cavity 111. The connecting hole seat 12 is fixed to the outer wall of the column body 11 and communicates with the first connecting hole 112. The protective cover 2 has a first opening 21 at the bottom. The mounting plate assembly 3 is disposed inside the protective cover 2 for mounting the communication antenna 100. The first end of the mounting plate assembly 3 is detachably connected to the inner wall of the protective cover 2. The side wall of the protective cover 2... Adjustably connected to the column body 11, used to adjust the included angle between the mounting plate assembly 3 and the column body 11; the variable diameter positioning cylinder 4 includes a first small diameter section 41 and a large diameter section 42 connected together, the outer wall of the second end of the mounting plate assembly 3 is inserted into the inner wall of the variable diameter positioning cylinder 4, the outer wall of the large diameter section 42 is inserted into the side wall of the first opening 21, and the large diameter section 42 is rotatably connected to the column body 11; the first sealing ring 5 is disposed between the first small diameter section 41 and the side wall of the first opening 21; the two ends of the telescopic cable tube 6 are respectively connected to the variable diameter positioning cylinder 4 and the connecting hole seat 12, used to allow the cable from the communication antenna 100 to pass through the variable diameter positioning cylinder 4 and the telescopic cable tube 6 into the inner cavity 111 of the column body 11.

[0039] The communication antenna protection device, through the adjustable connection structure between the protective cover 2 and the support column assembly 1, enables flexible adjustment of the orientation of the communication antenna 100, which is beneficial for optimizing signal coverage. The communication antenna protection device uses a variable-diameter positioning cylinder 4 that plugs into the bottom of the protective cover 2, combined with a first sealing ring 5 to achieve a seal at the interface, effectively preventing moisture and humidity intrusion and improving the sealing performance of the protective cover 2. A telescopic cable conduit 6 forms a continuous cable protection channel between the variable-diameter positioning cylinder 4 and the mounting column assembly 1, avoiding cable exposure and enhancing overall protection reliability. This communication antenna protection device, while maintaining a compact structure, balances the adjustable angle of the communication antenna 100, interface sealing, and cable protection, improving the adaptability and service life of the communication antenna 100 in complex environments.

[0040] like Figure 1 As shown, the variable diameter positioning cylinder 4 also includes a second small diameter section 43. The second small diameter section 43 and the first small diameter section 41 are respectively disposed at both ends of the large diameter section 42. The second small diameter section 43 is plugged into the telescopic conduit 6. By setting the second small diameter section 43 at the other end of the large diameter section 42, a direct and reliable connection between the variable diameter positioning cylinder 4 and the telescopic conduit 6 is achieved. The plug-in connection between the second small diameter section 43 and the telescopic conduit 6 not only facilitates installation and positioning and effectively limits the relative displacement between the two, improving connection stability, but also ensures the continuity and sealing of the cable channel.

[0041] In this embodiment, the telescopic conduit 6 is made of corrugated tubing. Corrugated tubing possesses excellent axial telescopicity and flexibility, enabling it to adapt to relative positional changes between the protective cover 2 and the mounting post assembly 1. This is particularly effective in preventing excessive bending or stress on the cable when adjusting the angle of the communication antenna 100. Its corrugated structure provides telescopic functionality while also offering some resistance to pressure and mechanical impact, helping to protect the internal cables from damage. Furthermore, corrugated tubing typically has good sealing performance, further preventing moisture, dust, and other foreign matter from entering the cable channel, thus improving overall protection reliability. This structure is compact, lightweight, and easy to install, making it suitable for the wiring protection of outdoor communication antennas 100.

[0042] like Figure 1 and Figure 2As shown, the mounting plate assembly 3 includes a first plate 31, a second plate 32, and a mounting cylinder 33. The first plate 31 and the second plate 32 are perpendicularly connected, and the mounting cylinder 33 is connected to the second plate 32. The first plate 31 extends axially along the variable-diameter positioning cylinder 4 and is used to mount the communication antenna 100. The second plate 32 extends radially along the variable-diameter positioning cylinder 4. The outer wall of the mounting cylinder 33 is inserted into the inner wall of the variable-diameter positioning cylinder 4, and the second plate 32 is used to limit the axial displacement of the mounting cylinder 33. The first plate 31 extends axially along the variable-diameter positioning cylinder 4, providing a stable mounting base for the communication antenna 100; the second plate 32 extends radially and is connected to the mounting cylinder 33, and its end face can effectively limit the axial movement of the mounting cylinder 33, enhancing the overall structural rigidity. The insertion and engagement of the outer wall of the mounting cylinder 33 with the inner wall of the variable-diameter positioning cylinder 4 achieves precise positioning while also facilitating assembly and angle adjustment. This structure not only improves the stability and accuracy of the installation of the communication antenna 100, but also takes into account adjustability and ease of maintenance, which helps to extend the service life of the communication antenna 100 in complex environments.

[0043] like Figure 2 As shown, the communication antenna protection device also includes a fastening spring 7. The first sealing ring 5 is stepped, and the fastening spring 7 is sleeved on the outer periphery of the small-diameter section of the first sealing ring 5, with its two ends abutting against the second plate 32 and the stepped surface of the first sealing ring 5, respectively. By using a stepped first sealing ring 5 and a fastening spring 7 on the outer periphery of its small-diameter section, the continuous elastic force of the spring presses the stepped surface of the first sealing ring 5 outward, significantly enhancing the sealing contact pressure between the first sealing ring 5 and adjacent components. This structure can effectively compensate for changes in the sealing gap caused by processing errors or long-term vibration, maintain stable sealing performance, and prevent moisture from entering the interior of the protective cover 2 from the interface, thereby improving the reliability of the communication antenna 100 during long-term operation in humid environments.

[0044] In this embodiment, the material of the first sealing ring 5 can be selected from ethylene propylene diene monomer (EPDM), silicone rubber (VMQ), fluororubber (FKM), or chloroprene rubber (CR). EPDM has excellent weather resistance, ozone resistance, and low-temperature resistance, making it suitable for a wide temperature range environment; silicone rubber (VMQ) has outstanding high and low temperature resistance, good resilience, and resistance to compression set; fluororubber (FKM) has excellent high-temperature resistance, oil resistance, and chemical resistance, making it suitable for harsh working conditions; chloroprene rubber (CR) has balanced overall performance, with good oil resistance, aging resistance, and mechanical strength. All of the above materials can provide a reliable elastic seal, adapting to outdoor humidity, temperature differences, and ultraviolet radiation, ensuring that the first sealing ring 5 maintains effective sealing force and structural integrity over a long period.

[0045] like Figure 2As shown, the sidewall of the first opening 21 extends inward to form an annular inner extension 22, which abuts against the stepped surface of the first sealing ring 5. The annular structure of this inner extension 22 allows for a surface-contact sealing fit with the stepped first sealing ring 5, significantly increasing the sealing contact area and improving the fit and uniformity of the sealing interface. Through the axial limiting and supporting effect of the inner extension 22 on the stepped surface of the first sealing ring 5, displacement or deformation of the first sealing ring 5 due to internal pressure or external vibration can be effectively prevented, ensuring the long-term stability of the seal. This structure effectively improves the static sealing and dynamic vibration resistance performance of the protective cover 2 at the interface, enhancing the overall water-proof and moisture-proof capabilities of the communication antenna protection device.

[0046] like Figure 2 As shown, the second plate 32 has a through hole 321, which is connected to the mounting cylinder 33 for cable passage. The through hole 321 provides a centralized and orderly cable path, avoiding messy cable arrangement inside the protective cover 2 and reducing the risk of signal transmission quality degradation due to bending and tangling. The cable can be directly introduced into the protective cover 2 and connected to the antenna through the internal space of the mounting cylinder 33 and the through hole 321. This not only simplifies the assembly process but also enhances the transition protection of the cable at moving parts, reduces the possibility of cable wear during repeated adjustments, and helps maintain the stability of the electrical connection and extend the cable's service life.

[0047] like Figure 1 and Figure 2 As shown, the mounting plate assembly 3 also includes a reinforcing plate 34, with adjacent sides of the reinforcing plate 34 used to connect the first plate 31 and the second plate 32, respectively. By adding the reinforcing plate 34 and forming a stable triangular or near-triangular support structure at the connection between the first plate 31 and the second plate 32, the overall rigidity and deformation resistance of the mounting plate assembly 3 are significantly enhanced. This structure can effectively distribute the stress generated by the weight of the communication antenna 100 and external vibrations, reduce fatigue damage at the connection between the first plate 31 and the second plate 32, and improve installation stability. The introduction of the reinforcing plate 34 improves the structural reliability of the mounting plate assembly 3 during long-term use, which is beneficial for maintaining antenna pointing accuracy and signal transmission quality.

[0048] like Figure 3As shown, the mounting plate assembly 3 includes four reinforcing plates 34, which are spaced apart on both sides of the first connecting plate. By symmetrically and spaced apart on both sides of the first plate 31, the overall stiffness and bending strength of the connection area between the first plate 31 and the second plate 32 are significantly enhanced. This symmetrical layout can evenly distribute loads and vibrations from different directions, effectively suppressing the twisting or resonance phenomena that may occur in the first plate 31 when installing a large or multi-band communication antenna 100, and improving structural stability. Specifically, in this embodiment, the first plate 31, the second plate 32, the mounting cylinder 33, and the reinforcing plates 34 are welded together.

[0049] like Figure 1 As shown, the inner wall of the protective cover 2 is provided with a limiting seat 23, and the limiting seat 23 is provided with a limiting groove 231. The first plate 31 is inserted into the limiting groove 231. Through the insertion and engagement of the limiting groove 231 and the first plate 31, the mounting plate assembly 3 is accurately positioned and quickly installed within the protective cover 2, effectively limiting the movement of the first plate 31 and enhancing the structural rigidity and stability of the communication antenna 100 installation. This limiting structure can distribute the external load on the communication antenna 100, reduce the impact of vibration on the connection parts, and facilitate the initial calibration of the installation angle during assembly, thereby improving the overall reliability and maintenance efficiency of the device.

[0050] like Figure 1 As shown, the communication antenna protection device also includes a second sealing ring 8, which is disposed between the connecting hole seat 12 and the telescopic conduit 6. By providing the second sealing ring 8 at the connection between the connecting hole seat 12 and the telescopic conduit 6, the assembly gap at the interface between the two is effectively filled, forming a reliable static sealing structure. The second sealing ring 8 can prevent environmental media such as rainwater and moisture from entering the inner cavity 111 of the column body 11 through the gap between the connecting hole seat 12 and the telescopic conduit 6, avoiding the risk of corrosion and short circuit of the internal cables.

[0051] Specifically, the material of the second sealing ring 8 is neoprene rubber. Neoprene rubber has good weather resistance, oil resistance, and ozone aging resistance, and can adapt to harsh environments such as outdoor temperature changes, ultraviolet radiation, and rain erosion for a long time. Under compression, it can provide a durable and stable elastic recovery force, ensuring that the interface between the connecting hole seat 12 and the telescopic conduit 6 maintains effective sealing pressure, delaying the decline in sealing performance caused by the aging of the second sealing ring 8 material, and significantly improving the service life and sealing reliability of this connection part.

[0052] like Figure 1As shown, the column assembly 1 also includes a first connector 16 and a second connector 17 that are rotatably connected. The end of the first connector 16 away from the second connector 17 is rotatably connected to the column body 11, and the end of the second connector 17 away from the first connector 16 is rotatably connected to the protective cover 2. By setting a dual-rotation connection structure, the protective cover 2 and the internal antenna can be flexibly adjusted with multiple degrees of freedom in the horizontal and pitch directions, significantly improving the precise control capability of the antenna orientation and the optimization potential of the signal coverage range. This structure can effectively adapt to different installation environments and signal coverage requirements, while dispersing the stress generated by external wind loads and vibrations, reducing the load on a single connection point, enhancing the stability and fatigue resistance of the overall structure, and extending the service life of the communication antenna protection device under complex working conditions.

[0053] like Figure 1 As shown, the column assembly 1 also includes a positioning ring 13, a locking seat 14, and a fastener 15. The positioning ring 13 is fixedly connected to the column body 11, and a positioning groove 131 is set around the side wall of the positioning ring 13. The locking seat 14 includes a locking ring 141 and a third connector 142. The locking ring 141 has an adjustment slot extending through to both end faces along its axial direction. The outer wall of the locking ring 141 and the adjustment slot have two radially extended portions 1411. The fastener 15 passes through the two extended portions 1411 to lock the locking ring 141 in the positioning groove 131. The third connector 142 is fixedly connected to the locking ring 141 and rotatably connected to the large-diameter section 42. This structure, through the cooperation of the positioning groove 131 and the locking ring 141, realizes the stepless adjustment and reliable locking of the protective cover 2 and the antenna in the horizontal direction. When the fastener 15 is loosened, the retaining ring 141 can rotate flexibly within the positioning groove 131, facilitating the adjustment of the orientation of the communication antenna 100. When the fastener 15 is tightened, the two extensions 1411 are compressed, locking the retaining ring 141 into the positioning groove 131, effectively maintaining the adjusted position. The third connector 142 rotatably connects the retaining ring 141 to the large-diameter section 42, further realizing the adjustment of the pitch direction. This structure significantly improves the flexibility and locking reliability of the angle adjustment of the communication antenna 100, adapting to various signal coverage requirements, while the overall structure is compact, facilitating installation and maintenance. In this embodiment, the fastener 15 is a combination of bolts and nuts. Specifically, the positioning ring 13 is welded to the column body 11.

[0054] Optionally, such as Figure 4As shown, the snap-fit ​​ring 141 can also adopt a split structure, specifically composed of two semicircular rings that fit together. The two semicircular rings are engaged in the positioning groove 131 of the positioning ring 13 and locked in place by the fastener 15. The third connecting piece 142 is fixedly connected to the outside of one of the semicircular rings. This split structure facilitates assembly and adjustment. During operation, simply engage the two semicircular rings in the positioning groove 131 and apply a clamping force using the fastener 15 to achieve a tight fit and reliable fixation between the snap-fit ​​ring 141 and the positioning groove 131. The third connecting piece 142 is fixed to a single semicircular ring, ensuring stable load transmission through the rotating connection structure between it and the large-diameter section 42. This design improves assembly convenience and maintenance efficiency while ensuring adjustment functionality and locking reliability.
