Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a fast locking mechanism and an antenna. Background Technology

[0002] Currently, antenna feeds are primarily secured to the antenna's central body using bolts. For antennas with a diameter exceeding 4.5 meters, the feed is installed at the center of the central body. Disassembling the feed requires operators to use tools to remove the fixing screws. In vehicle-mounted antenna configurations, disassembling and assembling the feed requires operators to stand on a maintenance ladder, which presents safety hazards due to its height and is inconvenient, while also being time-consuming. If the feed and antenna central body are fixed for an extended period, the contact surfaces become tightly fitted, making separation difficult.

[0003] Therefore, a fast locking mechanism and antenna are needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick locking mechanism and antenna that can improve safety, reduce the difficulty of operation, and shorten the time for disassembly and assembly.

[0012] In some embodiments, a guide groove is provided on the connecting rod along the extension direction of the connecting rod, and the connecting rod cooperates with the guide block through the guide groove.

[0013] In some embodiments, the guide groove is an arc-shaped groove or an inclined groove, and when the driving member drives the connecting rod to move away from the locking hook, the locking member can move radially away from the cylinder.

[0014] In some embodiments, the driving component is an electric cylinder, the cylinder body of which is fixedly mounted on the fixed plate, and the output end of the electric cylinder is rotatably connected to the connecting rod.

[0015] In some embodiments, a locking wheel is rotatably sleeved on the locking member.

[0016] In some embodiments, the ejection assembly includes a cylinder, a push rod, and an elastic element. The cylinder is fixedly mounted on the fixed plate, the push rod passes through the cylinder with one end extending out of the cylinder, the elastic element is located in the cylinder with one end abutting against the cylinder and the other end abutting against the push rod. When the locking assembly engages with the locking hook, the push rod abuts against the flange of the cylinder.

[0038] To facilitate the assembly and disassembly of the antenna feed source and center body, improve the safety of assembly and disassembly, reduce the difficulty of operation, and shorten the assembly and disassembly time, such as... Figures 1-7 As shown, this utility model provides a quick-locking mechanism. The quick-locking mechanism includes a fixed plate 1, a locking assembly 2, a locking hook 4, and an ejection assembly 3.

[0039] The fixing plate 1 is bolted to the central body 100, and a driving component 5 is mounted on the fixing plate 1. The locking assembly 2 is connected to the driving component 5. The locking hook 4 is fixed to the cylinder 210 of the feed source 200. The driving component 5 can drive the locking assembly 2 to move toward the locking hook 4 to engage with the locking hook 4, or to move away from the locking hook 4 to separate from the locking hook 4. The ejection assembly 3 is mounted on the fixing plate 1, and the ejection assembly 3 can push the contact surface between the cylinder 210 and the central body 100 to separate.

[0040] When the feed source 200 needs to be installed on the center body 100, the drive component 5 drives the locking assembly 2 to engage with the locking hook 4 on the cylinder 210, thereby connecting the feed source 200 to the center body 100. When the feed source 200 needs to be disassembled, the drive component 5 drives the locking assembly 2 to separate from the locking hook 4, and the push-out assembly 3 pushes out the cylinder 210, thus separating the feed source 200 from the center body 100. Through this method, automatic locking and unlocking of the feed source 200 can be achieved, improving safety, reducing operational difficulty, and shortening disassembly and assembly time.

[0041] In some embodiments, the locking assembly 2 includes a connecting rod 21 and a guide block 22. The connecting rod 21 is connected to the driving member 5, and the guide block 22 is fixedly mounted on the fixed plate 1. The connecting rod 21 and the guide block 22 are slidably connected. A locking member is provided at the end of the connecting rod 21, which can cooperate with the locking hook 4. With the above arrangement, during the process of the driving member 5 driving the connecting rod 21 to move the locking member, the guide block 22 plays a guiding role, so that the connecting rod 21 can only move along the set path, thereby ensuring that the connecting rod 21 can drive the locking member to cooperate with or separate from the locking hook 4.

[0042] In some embodiments, a guide groove 211 is provided on the connecting rod 21 along its extension direction, and the connecting rod 21 engages with the guide block 22 through the guide groove 211. By providing the guide groove 211, the guide groove 211 engages with the guide block 22 during the movement of the connecting rod 21, thereby ensuring that the connecting rod 21 moves along the trajectory set by the guide groove 211.

[0043] In some embodiments, the guide groove 211 is an arc-shaped groove or an inclined groove. When the driving member 5 drives the connecting rod 21 to move away from the locking hook 4, the locking member can move radially away from the cylinder 210. With the above arrangement, during the movement of the driving member 5 driving the connecting rod 21, the connecting rod 21 deflects at a certain angle while moving, thereby moving the locking member away from the locking hook 4. During the subsequent axial removal of the cylinder 210 of the feed source 200, interference between the cylinder 210 and the locking hook 4 is avoided, ensuring smooth subsequent disassembly and assembly processes.

[0044] In some embodiments, the driving component 5 is an electric cylinder, the cylinder body of which is fixedly mounted on the fixed plate 1, and the output end of the electric cylinder is rotatably connected to the connecting rod 21. The electric cylinder mainly consists of a motor and a lead screw and nut structure. The nut serves as the output end. During the rotation of the lead screw driven by the motor, the nut moves along the axial direction of the lead screw, thereby driving the connecting rod 21 connected to the nut to move. By controlling the forward and reverse rotation and the speed of the motor, the direction and speed of movement of the connecting rod 21 can be controlled, facilitating the control of the engagement or disengagement of the locking component and the locking hook 4. In other embodiments, a pneumatic cylinder or a motor-driven gear and rack structure can also be used as the driving component 5; no further restrictions are imposed here.

[0045] In some embodiments, a locking wheel 23 is rotatably sleeved on the locking member. This arrangement enables the friction generated by the engagement between the locking member and the locking hook 4 to be rolling friction, thereby reducing wear on the locking member and the locking hook 4.

[0046] In some embodiments, the ejection assembly 3 includes a cylinder 31, a push rod 32, and an elastic element. The cylinder 31 is fixedly mounted on the fixing plate 1. The push rod 32 passes through the cylinder 31, with one end of the push rod 32 extending out relative to the cylinder 31. The elastic element is located in the cylinder 31, with one end abutting against the cylinder 31 and the other end abutting against the push rod 32. When the locking assembly 2 engages with the locking hook 4, the push rod 32 abuts against the flange of the cylinder 210. In this embodiment, the elastic element is a compression spring. During the installation of the feed source 200, the feed source 200 pushes the push rod 32 to move, thereby compressing the elastic element. The locking assembly 2 cooperates with the locking hook 4 to lock the feed source 200. At this time, the elastic element is in a compressed and energy-storing state. When the locking assembly 2 is released from the locking hook 4, the push rod 32 abuts against the flange of the cylinder 210 under the action of the elastic element, and pushes the cylinder 210 to move relative to the center body 100, thereby separating the contact surfaces of the cylinder 210 and the center body 100. In other embodiments, an electric push rod or a cylinder can also be used as the ejection assembly 3, and no further restrictions are imposed here.

[0047] In some embodiments, a reinforcing rib 11 is provided on the side of the fixing plate 1 facing away from the driving member 5. By providing the reinforcing rib 11, the structural strength of the fixing plate 1 can be improved.

[0048] In some embodiments, the locking hook 4 has a first mounting hole, and the cylinder 210 has a second mounting hole opposite to the first mounting hole. A fastener passes through the first mounting hole and connects to the second mounting hole. In this embodiment, the fastener is a bolt. Installing the locking hook 4 in this manner facilitates quick assembly and disassembly.

[0049] This application also provides an antenna, which includes a central body 100, a feed 200, and a quick-locking mechanism as described above. The cylindrical body 210 of the feed 200 passes through the central body 100, and the quick-locking mechanism is disposed between the central body 100 and the cylindrical body 210. In this embodiment, two sets of quick-locking mechanisms are provided to ensure a stable connection between the feed 200 and the central body 100. By providing a quick-locking mechanism, safety can be improved, the difficulty of operation can be reduced, and the disassembly and assembly time can be shortened.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
