Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of antennas, and in particular to a quick locking mechanism and an antenna. Background Art
[0002] Existing antenna feeds are primarily fixed to the antenna center body with bolts. For antennas with a diameter exceeding 4.5 meters, the feed is installed in the center of the center body. When disassembling the feed, the operator needs to use tools to remove the fixing screws. When the antenna is in vehicle-mounted mode, disassembling and assembling the feed requires the operator to stand on a maintenance ladder. The operating position is relatively high, posing certain safety risks and inconvenient operation, and disassembly and assembly are relatively time-consuming. If the feed and the antenna center body are fixed for a long time, the contact surface will be tightly attached, making it difficult to separate the feed and the center body.
[0003] Therefore, a quick locking mechanism and an antenna are needed to solve the above problems. Summary of the Invention

For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.
[0036] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.
[0037] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.
[0038] In order to facilitate the disassembly and assembly of the feed source and the center body of the antenna, and to improve the safety of disassembly and assembly, reduce the difficulty of operation, and shorten the time of disassembly and assembly, such as Figure 1-Figure 7 As shown, the present invention provides a quick locking mechanism. The quick locking mechanism includes a fixing plate 1, a locking assembly 2, a locking hook 4 and a pushing assembly 3.
[0039] The fixing plate 1 is bolted to the central body 100 and is provided with a driving member 5. The locking assembly 2 is in driving connection with the driving member 5. The locking hook 4 is fixed to the cylindrical body 210 of the feed source 200. The driving member 5 can drive the locking assembly 2 toward the locking hook 4 to engage with it, or away from the locking hook 4 to disengage it. The ejection assembly 3 is provided on the fixing plate 1 and can push the cylindrical body 210 away from the contact surface of the central body 100.
[0040] When the feed source 200 needs to be installed on the central body 100, the driver 5 drives the locking assembly 2 to engage the locking hook 4 on the cylinder 210, thereby connecting the feed source 200 to the central body 100. When the feed source 200 needs to be removed, the driver 5 drives the locking assembly 2 to separate from the locking hook 4, and the ejection assembly 3 ejects the cylinder 210, thereby separating the feed source 200 from the central body 100. This method can achieve automatic locking and unlocking of the feed source 200, improve safety, reduce operational difficulty, and shorten assembly and disassembly time.
[0041] In some embodiments, the locking assembly 2 includes a connecting rod 21 and a guide block 22. The connecting rod 21 is in driving connection with the driving member 5. The guide block 22 is fixedly mounted on the fixed plate 1 and is slidably connected to the connecting rod 21. A locking member is provided at the end of the connecting rod 21, and the locking member can engage with the locking hook 4. Through the above arrangement, when the driving member 5 drives the connecting rod 21 to move the locking member, the guide block 22 acts as a guide, so that the connecting rod 21 can only move along a set path, thereby ensuring that the connecting rod 21 can drive the locking member to engage or disengage with the locking hook 4.
[0042] In some embodiments, a guide groove 211 is provided on the connecting rod 21 along the extension direction of the connecting rod 21, and the connecting rod 21 cooperates with the guide block 22 through the guide groove 211. By providing the guide groove 211, the guide groove 211 cooperates 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 arcuate groove or an oblique groove. When the driving member 5 drives the connecting rod 21 to move away from the locking hook 4, the locking member can move away from the cylinder 210 along the radial direction of the cylinder 210. Through the above arrangement, when the driving member 5 drives the connecting rod 21 to move, the connecting rod 21 deflects at a certain angle while moving, thereby moving the locking member away from the locking hook 4. When the cylinder 210 of the feed source 200 is subsequently removed along the axial direction, interference between the cylinder 210 and the locking hook 4 is avoided, thereby ensuring that the subsequent disassembly and assembly process proceeds smoothly.
[0044] In some embodiments, the driving member 5 is an electric cylinder, the cylinder body of the electric cylinder is fixedly set on the fixed plate 1, and the output end of the electric cylinder is rotatably connected to the connecting rod 21. The structure of the electric cylinder is mainly a motor and a screw-nut structure. The nut serves as the output end. In the process of the motor driving the screw to rotate, the nut moves along the axial direction of the screw, thereby driving the connecting rod 21 connected to the nut to move. By controlling the forward and reverse rotation and speed of the motor, the movement direction and speed of the connecting rod 21 can be controlled, which facilitates the control of the engagement or separation of the locking member and the lock hook 4. In other implementations, a cylinder can also be used as the driving member 5, or a motor-driven gear rack structure can be used as the driving member 5, and no excessive restrictions are made here.
[0045] In some embodiments, the locking member is rotatably sleeved with a locking wheel 23. Through the above arrangement, the friction generated by the cooperation between the locking member and the lock hook 4 can be rolling friction, thereby reducing the wear of the locking member and the lock hook 4.
[0046] In some embodiments, the ejection assembly 3 includes a cylinder 31, a push rod 32, and an elastic member. The cylinder 31 is fixedly mounted on the fixed plate 1, the push rod 32 is passed through the cylinder 31, and one end of the push rod 32 extends relative to the cylinder 31. The elastic member is located in the cylinder 31, and one end of the elastic member abuts against the cylinder 31, and the other end of the elastic member abuts against the push rod 32. When the locking assembly 2 is engaged with the locking hook 4, the push rod 32 abuts against the flange of the cylinder 210. In this embodiment, the elastic member 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 member, and the locking assembly 2 cooperates with the locking hook 4 to lock the feed source 200. At this time, the elastic member is in a compressed energy storage state. When the locking assembly 2 is separated from the locking hook 4 and in the released state, the push rod 32 abuts against the flange of the cylinder 210 under the action of the elastic member and pushes the cylinder 210 to move relative to the central body 100, thereby separating the contact surface between the cylinder 210 and the central body 100. In other embodiments, an electric push rod or a pneumatic cylinder can also be used as the pushing assembly 3, and no further restrictions are imposed here.
[0047] In some embodiments, a reinforcing rib 11 is provided on a 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 lock hook 4 has a first mounting hole, and the barrel 210 has a second mounting hole opposite 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. This method of mounting the lock hook 4 facilitates quick assembly and disassembly.
[0049] This application also provides an antenna comprising a central body 100, a feed source 200, and the aforementioned quick-locking mechanism. The cylindrical body 210 of the feed source 200 is inserted into 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 source 200 and the central body 100. The provision of the quick-locking mechanism improves safety, reduces operational difficulty, and shortens assembly and disassembly time.
