Description

Technical Field

[0001] This invention relates to the field of microwave antenna installation technology, and more specifically, to a quick-connect structure and a microwave antenna. Background Technology

[0002] Microwave antennas are the cornerstone of communication technology, widely used in radar, satellite communications, mobile networks, and other scenarios. They are responsible for transmitting and receiving microwave signals, enabling high-speed, long-distance information transmission. Their directional control and beamforming capabilities are crucial for improving communication quality and anti-interference capabilities. In national security, economic activities, and social life, the high efficiency and stable connection of microwave antennas are indispensable, driving the rapid development and widespread adoption of modern communication networks.

[0003] Existing microwave antennas are typically mounted on supporting structures such as towers or columns using bolts or mechanical clips. However, these installation methods often suffer from drawbacks such as cumbersome operation and time consumption, especially when working at heights. Adverse weather conditions, such as strong winds, rain, snow, high temperatures, or low temperatures, increase the difficulty and risk of installation, making precise alignment of bolt holes or operation of clips more challenging and posing a safety hazard to installers. Furthermore, the complex installation process may increase the demand for specialized tools and skills, further raising installation and maintenance costs. Summary of the Invention

[0004] The main objective of this invention is to provide a quick-connect structure and microwave antenna that can solve the problems of cumbersome installation and low installation efficiency of existing microwave antennas.

[0005] To achieve the above objectives, according to one aspect of the present invention, a quick-connect structure is provided, including a connecting plate, a connector, and a quick-connect member. The connecting plate includes a first connecting plate and a second connecting plate, with a clamping space formed between the first connecting plate and the second connecting plate. The connector is threadedly connected to at least one of the first connecting plate or the second connecting plate. The quick-connect member can be switched between a locked position and an unlocked position by rotation. When the quick-connect member is in the locked position, the quick-connect member can be snapped and fixed with at least one of the first connecting plate or the second connecting plate.

[0006] Furthermore, the quick-connect fitting includes a main body, the first end of which has a groove inside, a through hole on the surface of the main body corresponding to the groove, and a snap-fit ​​part inside the groove, which can slide inside the groove and extend out of the through hole.

[0007] Furthermore, the snap-fit ​​part includes a first guide surface, a second guide surface, a first stop surface, and a second stop surface. The first guide surface is disposed on the back side of the second stop surface, and the second guide surface is disposed on the back side of the first stop surface. The first stop surface is adjacent to the first guide surface and the second stop surface. The first guide surface is an inclined surface extending radially along the main body. The first guide surface gradually slopes away from the first end of the quick-connect piece from the inside to the outside. The cross-sectional area of ​​the second guide surface gradually decreases along the direction away from the main body. Both the first stop surface and the second stop surface are planes extending radially along the main body.

[0008] Furthermore, the first connecting plate is provided with a mounting hole, and a slot is provided in the mounting hole. When the locking part slides in the slot to the locking position, the locking part can extend through the hole and lock and fix with the slot.

[0009] Furthermore, the four mounting holes are arranged in a rectangular array at intervals, the quick-connect is provided at one diagonal of the rectangular array of mounting holes, the snap-fit ​​part includes a first stop surface facing the clamping space, and the connector is provided at the other diagonal of the rectangular array of mounting holes.

[0010] Furthermore, a pad is provided on the surface of the first connecting plate facing the clamping space, and the surface of the pad facing the clamping space is an arc-shaped surface.

[0011] Furthermore, the middle part of the second connecting plate is an arc-shaped plate.

[0012] Furthermore, a sliding part is provided inside the groove, and a snap-fit ​​part is fixedly provided on the sliding part. A stop protrusion is provided on the through hole, which can prevent the sliding part from sliding out of the through hole and detaching from the main body.

[0013] Furthermore, an end plate is provided at the second end of the main body, and a handle is fixedly installed on the end plate.

[0014] According to another aspect of the present invention, a microwave antenna is provided, including a quick-connect structure, a tray and an antenna body, the antenna body being disposed on the tray, the tray and the quick-connect structure being detachably connected, and the quick-connect structure being the quick-connect structure described above.

[0015] The technical solution of this invention includes a connecting plate comprising a first connecting plate and a second connecting plate, forming a clamping space between them. This clamping space can accommodate structures such as columns. The first and second connecting plates provide clamping force from both sides of the clamping space, enabling the quick-connect structure to be installed and fixed onto structures such as columns. The connector is typically a bolt, nut, or other fastener, threadedly connected to at least one of the first or second connecting plates, providing clamping force along the axial direction of the connector to improve the reliability of the quick-connect structure's fixation to the structure. The quick-connect is mainly used to axially lock and limit the first and second connecting plates along the quick-connect, preventing them from loosening axially and ensuring the installation stability and reliability of the quick-connect structure. After the worker places the connecting plate onto the column, they use the connector to clamp the connecting plate onto the column for initial fixation. Then, by rotating the quick-connect to the locked position, a stable installation of the quick-connect structure can be achieved without complex alignment or additional tightening steps. During disassembly, simply rotate the quick-connect fitting in the opposite direction to the unlocked position to easily separate the connecting plate from the column. The quick-connect structure provided by this invention simplifies the installation and disassembly process by incorporating the quick-connect fitting, significantly saving time and labor costs, while also reducing safety risks associated with working at heights.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1 to 8 As shown, the present invention provides a quick-connect structure, which includes a connecting plate 1, a connector 2, and a quick-connect member 3. The connecting plate 1 includes a first connecting plate 11 and a second connecting plate 12, and a clamping space is formed between the first connecting plate 11 and the second connecting plate 12. The connector 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12. The quick-connect member 3 can switch between a locked position and an unlocked position by rotation. When the quick-connect member 3 is in the locked position, the quick-connect member 3 can be snapped and fixed with at least one of the first connecting plate 11 or the second connecting plate 12.

[0029] In the above technical solution, the connecting plate 1 includes a first connecting plate 11 and a second connecting plate 12, forming a clamping space between them. This clamping space can accommodate structures such as the column 4. The first connecting plate 11 and the second connecting plate 12 provide clamping force from both sides of the clamping space, enabling the quick-connect structure to be installed and fixed on the structure such as the column 4. The connector 2 is typically a bolt, nut, or other fastener. The connector 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12, providing clamping force along the axial direction of the connector 2 to the first connecting plate 11 and the second connecting plate 12, thereby improving the fixing reliability between the quick-connect structure and the structure such as the column 4. The quick-connect 3 is mainly used to axially lock and limit the first connecting plate 11 and the second connecting plate 12 along the quick-connect 3, preventing the first connecting plate 11 and the second connecting plate 12 from loosening axially, and ensuring the installation stability and reliability of the quick-connect structure. After the worker places the connecting plate 1 onto the column 4, the connector 2 is used to clamp the connecting plate 1 onto the column 4 to complete the initial fixation. Then, the quick-connect fitting 3 is rotated to the locking position, thus achieving a stable installation of the quick-connect structure without complicated alignment or additional tightening steps. For disassembly, simply rotate the quick-connect fitting 3 in the opposite direction to the unlocked position to easily separate the connecting plate 1 from the column 4. The quick-connect structure provided by this invention simplifies the installation and disassembly process by incorporating the quick-connect fitting 3, significantly saving time and labor costs, while also reducing the safety risks of working at heights.

[0030] In one embodiment of the present invention, the quick connector 3 includes a main body 31. A groove 32 is provided inside the first end of the main body 31. A through hole 33 is provided on the groove 32 at a position corresponding to the surface of the main body 31. A snap-fit ​​part 34 is provided in the groove 32. The snap-fit ​​part 34 can slide in the groove 32 and extend out of the through hole 33.

[0031] In the above technical solution, the main body 31 is the main load-bearing structure of the quick-connect fitting 3, and houses structures such as the slide groove 32 and the locking part 34 inside the main body 31. The slide groove 32 is located inside the first end of the main body 31, and its function is to provide a moving track for the locking part 34, allowing the locking part 34 to retract into the slide groove 32 to achieve unlocking. The through hole 33 is opened on the surface of the main body 31 at a position corresponding to the slide groove 32, and its main function is to allow the locking part 34 to extend out of the main body 31 during sliding. The locking part 34 is the core component in the quick-connect fitting 3 that realizes the locking and unlocking functions. It can slide in the slide groove 32 and extend out of the through hole 33 to engage and fix with the slot 112 on the first connecting plate 11 or the second connecting plate 12.

[0032] In one embodiment of the present invention, the snap-fit ​​portion 34 includes a first guide surface 341, a second guide surface 342, a first stop surface 343, and a second stop surface 344. The first guide surface 341 is disposed on the back side of the second stop surface 344, and the second guide surface 342 is disposed on the back side of the first stop surface 343. The first stop surface 343 is adjacent to the first guide surface 341 and the second stop surface 344. The first guide surface 341 is an inclined surface extending radially along the main body. The first guide surface 341 gradually slopes from the inside to the outside in a direction away from the first end of the quick-connect member 3. The cross-sectional area of ​​the second guide surface 342 gradually decreases in a direction away from the main body. The first stop surface 343 and the second stop surface 344 are both planes extending radially along the main body.

[0033] In the above technical solution, the first guide surface 341 is mainly used to decompose the force of the locking part 34 on the locking part 34 by the inclined surface of the first guide surface 341 into two vertical components when the locking part 34 moves to the position of contacting the locking groove 112. This guide surface 341 guides the quick connector 3 to smoothly engage with the locking groove 112, avoiding hard collisions that could cause structural damage. Under the action of the component force along the sliding direction of the locking part 34, the locking part 34 retracts into the sliding groove 32 until the locking part 34 moves above the locking groove 112. At this time, the first guide surface 341 no longer contacts the locking groove 112. The locking part 34 then falls into the locking groove 112 under the action of gravity, thereby achieving the locking and fixing between the locking part 34 and the locking groove 112. The cross-sectional area of ​​the second guide surface 342 gradually decreases along the direction away from the main body 31. When the second guide surface 342 is mainly used to guide the locking part 34 to smoothly retract into the slide groove 32 when the quick connector 3 switches from the locked state to the unlocked state, it avoids the locking part 34 from hard collision with the slide groove 32 during the retraction process, which would cause structural damage. When the quick connector 3 is rotated in the opposite direction to unlock, the second guide surface 342 comes into contact with the inner wall of the slot 112. The slot 112 applies a component force along the sliding direction of the locking part 34 to the second guide surface 342. Under the action of this component force, the locking part 34 slides into the slide groove 32 until the second guide surface 342 disengages from the slot 112 and the second guide surface 342 is completely retracted into the slide groove 32. At this time, the quick connector 3 is rotated to the unlocked position and can be smoothly pulled out from the mounting hole 111, thereby releasing the connection and limiting of the quick connector 3 to the first connecting plate 11 and the second connecting plate 12. When the quick-connector 3 is in the locked state, the first stop surface 343 contacts the inner wall of the slot 112 on the back side of the second guide surface 342 to stop the locking part 34, ensuring that the locking part 34 can only retract when the quick-connector 3 is rotated in the opposite direction to unlock, and will not retract when the quick-connector 3 is rotated in the forward direction. When the quick-connector 3 is in the locked state, the second stop surface 344 contacts the inner wall of the slot 112 to axially stop and limit the locking part 34, ensuring that the locking part 34 cannot move away from the first guide surface 341 after being locked in the slot 112, thereby further ensuring the stability and reliability of the quick-connector 3 in locking the first connecting plate 11 and the second connecting plate 12 in the locked state.

[0034] In one embodiment of the present invention, the first connecting plate 11 is provided with a mounting hole 111 and a slot 112 is provided in the mounting hole 111. When the locking part 34 slides in the sliding groove 32 to the locking position, the locking part 34 can extend through the through hole 33 and lock and fix with the slot 112.

[0035] In the above technical solution, the mounting hole 111 provides a position for the quick-connect part 3 to pass through the first connecting plate 11, and plays a role in positioning and supporting the quick-connect part 3. The slot 112 cooperates with the snap-fit ​​part 34 to realize the snap-fit ​​fixation between the quick-connect part 3 and the first connecting plate 11. The hole 33 is an opening designed on the main body 31, which allows the snap-fit ​​part 34 to extend out of the main body 31 when it slides to the locked position, contact the slot 112 on the first connecting plate 11 and form a snap-fit.

[0036] In one embodiment of the present invention, four mounting holes 111 are arranged in a rectangular array at intervals, quick-connect member 3 is disposed at one diagonal of the rectangular array of mounting holes 111, snap-fit ​​part 34 includes a first stop surface 343 facing the clamping space, and connector 2 is disposed at the other diagonal of the rectangular array of mounting holes 111.

[0037] In the above technical solution, the four mounting holes 111 are arranged in a rectangular array at intervals, providing evenly distributed fixing points. This ensures that the first connecting plate 11 can be firmly and evenly clamped onto the column 4, avoiding asymmetrical force and deformation of the connecting plate that may be caused by single-point fixing. When the microwave antenna is installed on the first connecting plate 11, the quick-connect structure will generate a downward force at the end where the microwave antenna is installed under the gravity of the microwave antenna. Therefore, under the action of torque, the quick-connect structure tends to rotate around its center of gravity in the direction of the microwave antenna. The quick-connect piece 3 is arranged along one diagonal of the rectangular array of mounting holes 111. The contact between the quick-connect piece 3 and the column 4 effectively prevents the quick-connect structure from rotating. The first stop surface 343 of the snap-fit ​​part 34 is oriented towards the clamping space, so that the quick-connect pieces 3 on the left and right sides of the column 4 need to rotate in opposite directions to unlock them. This design can further improve the reliability of the locking and fixing of the quick-connect pieces 3 and avoid the situation where the quick-connect pieces 3 on the left and right sides of the column 4 rotate in the same direction at the same time when the quick-connect structure is subjected to vibration or rotational interference in the same direction, resulting in accidental unlocking. The connector 2 is located at the other diagonal of the rectangular array of mounting holes 111, so that the axial force applied by the connector 2 to the first connecting plate 11 and the second connecting plate 12 is more uniform, thereby improving the clamping effect and reliability of the first connecting plate 11 and the second connecting plate 12 on the column 4.

[0038] In one embodiment of the present invention, a pad 113 is provided on the surface of the first connecting plate 11 facing the clamping space, and the surface of the pad 113 facing the clamping space is an arc-shaped surface.

[0039] In the above technical solution, when the column 4 is placed in the clamping space, by setting a pad 113 on the surface of the first connecting plate 11 facing the clamping space, the hard contact between the surface of the first connecting plate 11 and the surface of the column 4 is reduced, the wear of the first connecting plate 11 is reduced, and the service life is extended, thereby reducing the risk of fixing failure due to poor contact or wear. Setting the surface of the pad 113 facing the clamping space as an arc surface can significantly increase the contact area between the pad 113 and the column 4, and make the surface of the pad 113 fit better with the outer contour of the column 4, which helps to disperse the pressure of the column 4 on the first connecting plate 11 and avoid structural deformation or damage caused by excessive local pressure.

[0040] In one embodiment of the present invention, the middle part of the second connecting plate 12 is an arc-shaped plate 121.

[0041] In the above technical solution, the design of the arc plate 121 allows the second connecting plate 12 to better fit the outer surface of the column 4 and form an arc surface contact. Compared with the planar contact, this design can increase the contact area, distribute pressure, reduce local stress concentration, and make the second connecting plate 12 more firmly fixed on the column 4.

[0042] In one embodiment of the present invention, a sliding part 35 is provided in the groove 32, a snap-fit ​​part 34 is fixedly provided on the sliding part 35, and a stop protrusion 36 is provided on the through hole 33. The stop protrusion 36 can prevent the sliding part 35 from sliding out of the through hole 33 and detaching from the main body 31.

[0043] In the above technical solution, the stop protrusion 36 is mainly used to prevent the locking part 34 and the sliding part 35 from completely sliding out of the slide groove 32 and detaching from the main body 31 during the sliding process in the slide groove 32. The locking part 34 is fixedly mounted on the sliding part 35. When the locking part 34 extends into the locking groove 112 for locking and limiting, the stop protrusion 36 can block the sliding part 35, preventing the sliding part 35 from sliding out of the through hole 33 along with the locking part 34 during installation or disassembly.

[0044] In one embodiment of the present invention, an end plate 311 is provided at the second end of the main body 31, and a handle 312 is fixedly provided on the end plate 311.

[0045] In the above technical solution, the end plate 311 is located at the second end of the main body 31. On the one hand, the end plate 311 can serve as a stop structure to prevent the quick connector 3 from being inserted too deeply and coming out from the side of the mounting hole 111 away from the insertion direction when the quick connector 3 is inserted through the mounting hole 111 onto the first connecting plate 11 and the second connecting plate 12. On the other hand, the end plate 311 serves as the mounting base for the handle 312, improving the fixing strength and reliability of the handle 312.

[0046] In one embodiment of the present invention, a rotation indicator is provided on the end plate 311, which indicates the locking rotation direction or the unlocking rotation direction of the quick connector 3.

[0047] In the above technical solution, by setting a rotation indicator, the operator is informed of the accurate rotation direction when locking or unlocking the quick connector 3, so as to avoid the situation where the quick connector 3 is rotated in the wrong direction, resulting in incorrect unlocking or locking, thereby improving the reliability and efficiency of installation.

[0048] In one embodiment of the present invention, the surface of the main body 31 is provided with anti-slip texture 313.

[0049] In the above technical solution, the anti-slip texture 313 on the surface of the main body 31 is mainly used to provide additional friction, reducing the risk of the quick-connect part 3 slipping and falling when the operator picks up and installs it. Furthermore, after the quick-connect part 3 is installed in the locking position, the anti-slip texture 313 contacts the inner wall of the mounting hole 111, increasing the friction between the main body 31 and the mounting hole 111 and reducing the probability of the anti-slip texture 313 slipping circumferentially. Simultaneously, the quick-connect part 3 fits tightly against the column 4, and the anti-slip texture 313 on the main body 31 contacts the surface of the column 4, increasing the friction between the main body 31 and the column 4, thereby improving the clamping and fixing effect of the quick-connect part 3 on the column 4.

[0050] See also Figures 1 to 8 As shown, the present invention also provides a microwave antenna, including a quick-connect structure, a support plate 5 and an antenna body 6. The antenna body 6 is disposed on the support plate 5, and the support plate 5 and the quick-connect structure are detachably connected. The quick-connect structure is the quick-connect structure of the above embodiment.

[0051] In the above technical solution, the support plate 5 is located between the antenna body 6 and the quick-connect structure. Its main function is to support the antenna body 6 and provide a flat surface for stable placement of the antenna body 6. Simultaneously, the support plate 5 and the quick-connect structure are connected by detachable means such as bolts, allowing for replacement or maintenance of the antenna body 6 without disassembling the entire quick-connect structure, greatly simplifying the maintenance process and improving work efficiency. By adopting the quick-connect structure in the above embodiment, the steps for installing and fixing the microwave antenna are simplified, the installation efficiency of the microwave antenna is improved, and the installation difficulty is reduced.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: The connecting plate 1 includes a first connecting plate 11 and a second connecting plate 12, forming a clamping space between the first connecting plate 11 and the second connecting plate 12. This clamping space can accommodate structures such as the column 4. The first connecting plate 11 and the second connecting plate 12 provide clamping force from both sides of the clamping space, enabling the quick-connect structure to be installed and fixed on structures such as the column 4. The connector 2 is usually a bolt, nut, or other fastener. The connector 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12, providing clamping force along the axial direction of the connector 2 to the first connecting plate 11 and the second connecting plate 12, improving the fixing reliability between the quick-connect structure and structures such as the column 4. The quick-connect 3 is mainly used to axially lock and limit the first connecting plate 11 and the second connecting plate 12 along the quick-connect 3, preventing the first connecting plate 11 and the second connecting plate 12 from loosening along the axial direction, and ensuring the installation stability and reliability of the quick-connect structure. After the worker places the connecting plate 1 onto the column 4, the connector 2 is used to clamp the connecting plate 1 onto the column 4 to complete the initial fixation. Then, the quick-connect fitting 3 is rotated to the locking position, thus achieving a stable installation of the quick-connect structure without complicated alignment or additional tightening steps. For disassembly, simply rotate the quick-connect fitting 3 in the opposite direction to the unlocked position to easily separate the connecting plate 1 from the column 4. The quick-connect structure provided by this invention simplifies the installation and disassembly process by incorporating the quick-connect fitting 3, significantly saving time and labor costs, while also reducing the safety risks of working at heights.
