Description

Technical Field

[0001] The utility model relates to the field of Beidou positioning antenna assembly, in particular to a snap - type assembly structure for the shell of a Beidou positioning antenna. Background Technique

[0002] The Beidou positioning antenna is a special antenna for receiving signals from the Beidou satellite navigation system. The Beidou satellite navigation system is a global satellite navigation system independently built and operated by China. Together with the GPS of the United States, the system of Russia, and the system of the European Union, it is known as one of the four major global satellite navigation systems.

[0003] The assembly of the shell of the Beidou positioning antenna is an important link to ensure that the antenna can work stably in various environments. The shell not only protects the internal antenna components but also ensures good signal reception.

[0004] However, most of the existing shells of Beidou positioning antennas and their assembly structures usually consist of a sealing ring, screws, protective tape, and a bottom shell. During assembly, the shell and the bottom shell need to be docked first, and then the basic assembly is completed through threaded through - holes and screws. Then, the assembled shell is reinforced with a sealing ring and protective tape, etc. However, this method is relatively cumbersome and time - consuming. And in the case of long - term use or harsh environments, there may be a situation of seal failure, resulting in internal components getting damp or damaged. Especially when disassembling, it is necessary to unscrew the screws one by one, which is time - consuming and laborious. And after multiple disassembly and assembly operations, the screws may become loose or damaged, affecting the stability of the overall structure. Content of the Utility Model

[0021] As Figure 2 and Figure 3As shown in the figure, the limiting mechanism includes a lifting plate 6, a rotating frame 7, a sliding block 8, a clamping block 9, a spring 10 and a clamping ring 11. A lifting plate 6 is arranged at the top of the connecting ring 5, and the inner side of the lifting plate 6 is slidably connected to the outer side of the thread. The outer side of the lifting plate 6 is symmetrically hinged with rotating frames 7 in the circumferential direction for driving the forward and backward movement of the clamping block 9.

The limiting blocks 14 and the limiting plates 15 are clamped and matched, which can further enhance the structural stability.

[0023] During assembly, first place the base 1 at the desired position, then screw the threaded rod 2 into the threaded hole at the top of the base 1 until it is firmly fixed; then adjust the height of the threaded rod 2 as needed and ensure that it is perpendicular to the base 1. The base 1 and the threaded rod 2 are tightly connected through the threaded hole. Subsequently, put the turntable 4 on the threaded rod 2, and then screw the threaded sleeve 3 on the threaded rod 2 to fix the height of the turntable 4. Then slide the connecting ring 5 to the outside of the threaded sleeve 3 and adjust the position so that it fits with the top of the turntable 4. The turntable 4 is fixed on the threaded rod 2 through the threaded sleeve 3. The connecting ring 5 slides on the outside of the threaded sleeve 3 to ensure a stable connection. Next, put the lower shell 101 on the outside of the turntable 4 to ensure that it covers the turntable 4 and is higher than the turntable 4. Then ensure that the lower shell 10 1, the bottom of the lower shell 101 is fitted with the middle of the turntable 4, so that the lower shell 101 is firmly fixed on the turntable 4, and the lower shell 101 covers the outside of the turntable 4 to form a complete shell bottom structure. Then, the middle shell 102 is installed on the top of the lower shell 101, and then the antenna module 12 is installed in the center of the top of the middle shell 102, ensuring that the connecting antenna 13 passes through the lower shell 101 and extends outward. The middle shell 102 is installed on the top of the lower shell 101, and the antenna module 12 is located in the center of the top of the middle shell 102 to ensure smooth signal transmission. Next, the lifting plate 6 is installed on the top of the connecting ring 5, and then the card block 9 is installed in the slide groove inside the middle shell 102 through the sliding block 8 and the rotating frame 7 to ensure that the card block 9 slides freely, and then the position of the card block 9 is adjusted to make it in the absence of the snap ring 11. The upper shell 103 is clamped at the top of the middle shell 102 to ensure a tight fit, and then the clamping ring 11 is ensured to cooperate with the clamping block 9, so that the upper shell 103 is firmly fixed on the middle shell 102, and the limit block 14 in the upper shell 103 is clamped with the limit plate 15 at the top of the middle shell 102 to enhance the structural stability. The upper shell 103 is clamped to the top of the middle shell 102 to ensure a firm connection; when disassembling, first manually rotate the turntable 4 so that the turntable 4 and the threaded sleeve 3 are threaded and drive the connecting ring 5 to move, so that the connecting ring 5 pushes the lifting plate 6, and then the rotating frame 7 drives the clamping block 9 to move upward and disengage from the middle shell. The sliding groove inside 102, the lifting plate 6 drives the rotating frame 7 to disengage the block 9 from the sliding groove, and release the locking state of the upper shell 103 and the middle shell 102. Then, the upper shell 103 is removed from the limiting mechanism to ensure that the snap ring 11 is separated from the block 9. The snap ring 11 is separated from the block 9, so that the upper shell 103 can be easily removed. Then, the middle shell 102 is gently lifted up to separate it from the lower shell 101. The middle shell 102 is separated from the lower shell 101, so that the antenna module 12 can be taken out from the lower shell 101, and then the connecting ring 5 is slid off the threaded sleeve 3, and the turntable 4 is removed. The connecting ring 5 slides down, and the turntable 4 is removed accordingly. Finally, the threaded rod 2 is unscrewed from the base 1 to complete the entire disassembly process. The threaded rod 2 is unscrewed to complete the disassembly of the entire structure.
