[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the 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 connecting piece 2 and a quick-connect piece 3. The connecting plate 1 includes a first connecting plate 11 and a second connecting plate 12. A clamping space is formed between the first connecting plate 11 and the second connecting plate 12. The connecting piece 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12. The quick-connect piece 3 can be switched between a locked position and an unlocked position by rotation. When the quick-connect piece 3 is in the locked position, the quick-connect piece 3 can be clamped 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, and a clamping space is formed between the first connecting plate 11 and the second connecting plate 12. The clamping space can accommodate structures such as the column 4. The first connecting plate 11 and the second connecting plate 12 provide clamping force inward from both sides of the clamping space, so that the quick-connect structure can be installed and fixed on the structure such as the column 4. The connecting member 2 is usually a bolt, a nut or other fastener. The connecting member 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12, providing the first connecting plate 11 and the second connecting plate 12 with a clamping force along the axial direction of the connecting member 2, thereby improving the fixing reliability between the quick-connect structure and the structure such as the column 4. The quick-connect member 3 is mainly used to axially lock and limit the first connecting plate 11 and the second connecting plate 12 along the quick-connect member 3, so as to prevent the first connecting plate 11 and the second connecting plate 12 from loosening along the axial direction, thereby ensuring the installation stability and reliability of the quick-connect structure. After the staff puts the connecting plate 1 on the column 4, they use the connecting piece 2 to clamp the connecting plate 1 to the column 4 to complete the initial fixation, and then rotate the quick connector 3 to the locking position to achieve the stable installation of the quick-connect structure without complicated alignment or additional fastening steps. When disassembling, just rotate the quick connector 3 in the opposite direction to put it in the unlocked position, and the connecting plate 1 and the column 4 can be easily separated. The quick-connect structure provided by the present invention simplifies the installation and disassembly process of the quick-connect structure by setting the quick connector 3, greatly saving time and labor costs, and also reducing the safety risks of high-altitude operations.

[0030] In one embodiment of the present invention, the quick connector 3 includes a main body 31, a slide groove 32 is provided inside the first end of the main body 31, a through hole 33 is opened at a position of the slide groove 32 corresponding to the surface of the main body 31, and a clamping portion 34 is provided in the slide groove 32, and the clamping portion 34 can slide in the slide groove 32 and extend out of the through hole 33.

[0031] In the above technical solution, the main body 31 is the main bearing structure of the quick connector 3, and the main body 31 contains structures such as the slide groove 32 and the clamping part 34. The slide groove 32 is arranged inside the first end of the main body 31, and its function is to provide a moving track for the clamping part 34, and to enable the clamping part 34 to be retracted into the slide groove 32 to achieve unlocking. A through hole 33 is provided 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 clamping part 34 to extend out of the main body 31 during the sliding process. The clamping part 34 is the core component of the quick connector 3 to realize the locking and unlocking functions. It can slide in the slide groove 32 and extend through the hole 33 to be clamped and fixed with the clamping groove 112 on the first connecting plate 11 or the second connecting plate 12.

[0032] In one embodiment of the present invention, the clamping 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 arranged on the back side of the second stop surface 344, and the second guide surface 342 is arranged 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 along the radial direction of the main body. The first guide surface 341 gradually inclines from the inside to the outside in a direction away from the first end of the quick connector 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 along the radial direction of the main body.

[0033] In the above technical solution, the first guide surface 341 is mainly used for when the clamping part 34 moves to the position in contact with the clamping slot 112, the force of the clamping slot 112 on the clamping part 34 is decomposed into two vertical components through the inclined surface of the first guide surface 341, thereby guiding the quick connector 3 to smoothly clamp with the clamping slot 112 to avoid structural damage caused by hard collision. Under the action of the component force along the sliding direction of the clamping part 34, the clamping part 34 is retracted into the slide groove 32 until the clamping part 34 moves to above the clamping slot 112, and the first guide surface 341 is no longer in contact with the clamping slot 112. At this time, the clamping part 34 falls into the clamping slot 112 under the action of gravity, thereby realizing the clamping fixation between the clamping part 34 and the clamping slot 112. The cross-sectional area of ​​the second guide surface 342 gradually decreases in the direction away from the main body 31. When the second guide surface 342 is mainly used to guide the clamping part 34 to smoothly retract into the slide groove 32 when the quick connector 3 switches from the locked state to the unlocked state, so as to avoid the clamping part 34 from hard collision with the slide groove 32 during the retraction process and causing structural damage. When the quick connector 3 is rotated in the opposite direction to unlock, the second guide surface 342 contacts the inner wall of the clamping groove 112, and the clamping groove 112 applies a component force along the sliding direction of the clamping part 34 to the second guide surface 342. Under the action of the component force, the clamping part 34 slides into the slide groove 32 until the second guide surface 342 is out of contact with the clamping groove 112, and the second guide surface 342 is completely retracted into the slide groove 32. At this time, the quick connector 3 rotates to the unlocked position and can be smoothly withdrawn from the mounting hole 111, thereby releasing the connection and limit 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 clamping portion 34, ensuring that the clamping portion 34 can only be retracted when the quick connector 3 is rotated in the reverse direction to unlock, and will not be retracted 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 the clamping portion 34, ensuring that the clamping portion 34 cannot move away from the first guide surface 341 after being clamped and fixed in the slot 112, thereby further ensuring the stability and reliability of the quick connector 3 in locking and fixing the first connecting plate 11 and the second connecting plate 12 in the locked state.

[0034] In one embodiment of the present invention, a mounting hole 111 is provided on the first connecting plate 11 , and a card slot 112 is provided in the mounting hole 111 . When the card portion 34 slides to a locking position in the slide slot 32 , the card portion 34 can extend through the hole 33 and be fixedly engaged with the card slot 112 .

[0035] In the above technical solution, the mounting hole 111 provides a position for the quick connector 3 to penetrate the first connecting plate 11, and plays a role in positioning and supporting the quick connector 3. The clamping groove 112 cooperates with the clamping portion 34 to achieve the clamping fixation between the quick connector 3 and the first connecting plate 11. The through hole 33 is an opening designed on the main body 31, which allows the clamping portion 34 to extend out of the main body 31 when sliding to the locking position, and contact with the clamping groove 112 on the first connecting plate 11 to form a clamping connection.

[0036] In one embodiment of the present invention, four mounting holes 111 are arranged in a rectangular array, the quick connector 3 is arranged at a diagonal corner of the rectangular array of mounting holes 111, the clamping portion 34 includes a first stop surface 343, the first stop surface 343 faces the clamping space, and the connecting member 2 is arranged at another diagonal corner 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, which can provide evenly distributed fixing points, so that the first connecting plate 11 can be firmly and evenly clamped on the column 4, avoiding the asymmetric 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 one end of the microwave antenna under the action of the gravity of the microwave antenna. Therefore, the quick-connect structure has a tendency to rotate around the center of gravity of the quick-connect structure in the direction of the microwave antenna under the action of the torque. The quick-connect member 3 is set along a diagonal of the rectangular array of mounting holes 111, and the abutment between the quick-connect member 3 and the column 4 can effectively prevent the quick-connect structure from rotating. The first stop surface 343 of the clamping portion 34 is arranged toward the clamping space, so that the quick connectors 3 on the left and right sides of the column 4 need to rotate in opposite directions to unlock the quick connectors 3. This design can further improve the reliability of the locking and fixing of the quick connectors 3, and prevent the quick connectors 3 on the left and right sides of the column 4 from rotating in the same direction at the same time when the quick connection structure is subjected to vibration or rotation interference in the same direction, resulting in accidental unlocking. The connector 2 is arranged at another 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 effect and reliability of the first connecting plate 11 and the second connecting plate 12 clamping the column 4.

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

[0039] In the above technical solution, when the column 4 is set in the clamping space, by setting the pad 113 on the surface of the first connecting plate 11 facing the clamping space, the hard contact between 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 fixation failure caused by 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 and the outer contour of the column 4 form a better fit, 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 portion 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 enables the second connecting plate 12 to better fit the outer surface of the column 4 to form an arc surface contact. Compared with the plane contact, this design can increase the contact area, distribute the pressure, reduce the 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 portion 35 is provided in the slide groove 32, the clamping portion 34 is fixedly provided on the sliding portion 35, and a stop protrusion 36 is provided on the through hole 33, which can prevent the sliding portion 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 clamping portion 34 and the sliding portion 35 from completely sliding out of the sliding groove 32 and then detaching from the main body 31 during the sliding process of the sliding groove 32. The clamping portion 34 is fixedly arranged on the sliding portion 35. When the clamping portion 34 extends into the clamping groove 112 for clamping and limiting, the stop protrusion 36 can block the sliding portion 35, preventing the sliding portion 35 from sliding out of the through hole 33 along with the clamping portion 34 during the installation or removal process.

[0044] In one embodiment of the present invention, an end plate 311 is disposed at the second end of the main body 31 , and a handle 312 is fixedly disposed 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 on the first connecting plate 11 and the second connecting plate 12. On the other hand, the end plate 311 serves as the installation base of the handle 312 to improve the fixing strength and reliability of the handle 312.

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

[0047] In the above technical solution, a rotation mark is set to inform the operator of the exact rotation direction when locking or unlocking the quick connector 3, thereby avoiding the situation where the quick connector 3 is rotated in the wrong direction and causes incorrect unlocking or locking, thereby improving the reliability and efficiency of the installation.

[0048] In one embodiment of the present invention, anti-slip grooves 313 are provided on the surface of the main body 31 .

[0049] In the above technical solution, by setting the anti-skid pattern 313 on the surface of the main body 31, it is mainly used to provide additional friction, so as to reduce the risk of the operator slipping and dropping the quick connector 3 when picking up and installing the quick connector 3. In addition, after the quick connector 3 is installed to the locked position, the anti-skid pattern 313 contacts the inner wall of the mounting hole 111, which can increase the friction between the main body 31 and the mounting hole 111 and reduce the probability of the anti-skid pattern 313 slipping off along the circumferential direction. At the same time, the quick connector 3 fits tightly with the column 4, and the anti-skid pattern 313 on the main body 31 contacts the surface of the column 4, which can increase the friction between the main body 31 and the column 4, thereby improving the clamping and fixing effect of the quick connector 3 on the column 4.

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

[0051] In the above technical solution, the support plate 5 is located between the antenna body 6 and the quick-connect structure, and its main function is to carry the antenna body 6 and provide a plane on which the antenna body 6 can be stably placed. At the same time, the support plate 5 and the quick-connect structure are connected in a detachable manner such as bolts, so that when replacing or maintaining the antenna body 6, there is no need to disassemble the entire quick-connect structure, which greatly simplifies the maintenance process and improves work efficiency. By adopting the quick-connect structure in the above embodiment, the steps of installing and fixing the microwave antenna are simplified, the installation efficiency of the microwave antenna is improved, and the installation difficulty is reduced.

The first connecting plate 11 and the second connecting plate 12 provide clamping force inward from both sides of the clamping space, so that the quick-connect structure can be installed and fixed on the structure such as the column 4. The connecting member 2 is usually a bolt, a nut or other fastener, and the connecting member 2 is threadedly connected to at least one of the first connecting plate 11 or the second connecting plate 12, providing the first connecting plate 11 and the second connecting plate 12 with a clamping force along the axial direction of the connecting member 2, thereby improving the fixing reliability between the quick-connect structure and the structure such as the column 4. The quick-connect member 3 is mainly used to axially lock and limit the first connecting plate 11 and the second connecting plate 12 along the quick-connect member 3, so as to prevent the first connecting plate 11 and the second connecting plate 12 from loosening along the axial direction, and ensure the installation stability and reliability of the quick-connect structure. After the staff puts the connecting plate 1 on the column 4, they use the connecting piece 2 to clamp the connecting plate 1 to the column 4 to complete the initial fixation, and then rotate the quick connector 3 to the locking position to achieve the stable installation of the quick-connect structure without complicated alignment or additional fastening steps.
