Description

Technical Field

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

[0002] In today's rapidly developing communication technology, backpack antennas are key equipment in scenarios such as field operations and emergency communications, and their performance and convenience directly affect communication quality and work efficiency. Existing backpack antennas have relatively simple connection methods to their housings, mostly using plug-and-play or bolt fixing. When walking in complex terrain or engaging in strenuous activity, the antenna is prone to loosening or even falling off. Furthermore, most backpack antenna housings and frames use traditional bolt connections or simple snap-fit ​​structures, making assembly and disassembly extremely inconvenient. For backpack antennas with bolt connections, assembly requires the use of screwdrivers and other tools to tighten multiple bolts one by one, a time-consuming and laborious process that can easily cause localized deformation of the housing or frame due to uneven force. Disassembly also requires operating on each bolt sequentially; in complex environments such as the field, lack of tools or limited operating space further increases the difficulty of assembly and disassembly, seriously affecting the timeliness of emergency communications and other tasks. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses a backpack antenna, comprising a housing 1. Multiple mounting holes are provided on the top surface of the housing 1, into which an antenna 3 is inserted. Two connecting blocks 6 are symmetrically arranged on one side of the housing 1, each with a snap-fit ​​assembly. A mounting frame 5 is fixedly connected to the connecting blocks 6 via the snap-fit ​​assembly. A guide groove 9 for inserting the connecting blocks 6 is provided on one side of the mounting frame 5. A base plate 4 is fixedly connected to the bottom of the mounting frame 5. Two shoulder straps 2 are symmetrically arranged on one side of the mounting frame 5. The bottom surface of the housing 1 abuts against the top surface of the base plate 4. The housing 1 and mounting frame 5 are made of high-strength engineering plastic, which is lightweight and strong. Quick docking is achieved through the cooperation of the snap-fit ​​assembly and the guide groove 9. The shoulder straps 2 are made of non-slip, wear-resistant nylon with a specially treated surface. Their symmetrical arrangement conforms to ergonomics, improving the portability and efficiency of the device. The snap-fit ​​assembly includes multiple mounting grooves on one side of the two connecting blocks 6, each containing a spring 8. One end of the spring 8 is fixedly connected to a locking block 7. A rectangular through groove is opened on the opposite surface of the mounting frame 5 and the connecting block 6. A slider 14 is installed in the rectangular through groove. Multiple locking slots 10 corresponding to the locking block 7 are opened on the opposite surface of the slider 14 and the connecting block 6. The spring 8 is model YZ-50, which has good elasticity and fatigue resistance. Its elastic cooperation with the locking block 7 allows the housing 1 and the mounting frame 5 to automatically lock together when they are connected. The design of the slider 14 and the locking slots 10 can further adjust the locking strength. Three sleeves are equidistantly arranged on one side of the slider 14. A threaded rod 11 is rotatably installed in one of the three sleeves. Guide posts 12 are sleeved in the other two of the three sleeves. The threaded rod 11 is model TR12×3, which has high transmission efficiency. Its cooperation with the guide post 12 converts the rotational motion into linear motion, realizing precise displacement control of the slider 14. Compared with traditional bolt connections, the operation is simpler and faster, improving the efficiency of equipment assembly.

[0020] In this utility model, both the threaded rod 11 and the guide post 12 are mounted on the mounting frame 5. One end of the threaded rod 11 passes through the outer wall of the mounting frame 5 and is coaxially fixed to a knob 13. By rotating the threaded rod 11 through the knob 13, the slider 14 can be remotely controlled to move without additional tools, making operation more convenient in complex environments such as the field. The threaded rod 11 is model TR12×3, ensuring the stability and accuracy of the transmission. A groove 16 is provided in the mounting hole, and a connecting post is fixedly connected to the bottom of the antenna 3. Multiple expansion plates 15 are fixedly connected to the bottom surface of the connecting post along the axial side. The lower end of the expansion plate 15 is provided with a protrusion 17 corresponding to the groove 16. The antenna 3 adopts... Made of aluminum alloy, it has good conductivity and corrosion resistance. The interlocking structure of the expansion plate 15 and the groove 16 makes the connection between the antenna 3 and the housing 1 tighter, improving the stability of signal transmission. A limiting ring is fixedly installed in the middle of the outer wall of the expansion plate 15. An expansion post is sleeved inside the expansion plate 15. The top of the expansion post passes through the gap between multiple expansion plates 15 and is fixedly installed with an abutment ring 18 sleeved on the outer wall of the expansion plate 15. By pushing the abutment ring 18, the expansion post is controlled to open or close the expansion plate 15, realizing the quick installation and disassembly of the antenna 3. The operation is simple and the connection is firm. The expansion plate 15 is made of high-strength alloy material to ensure structural strength and durability.

[0021] Working principle: When using this utility model, first align the connecting block 6 of the housing 1 with the guide groove 9 of the mounting frame 5 and insert it. The spring 8 in the mounting groove of the connecting block 6 is in its natural state. The locking block 7 extends out of the mounting groove under the elastic force of the spring 8. When the connecting block 6 is fully inserted into the guide groove 9, the locking block 7 is aligned with the locking groove 10 on the slider 14. The spring 8 pushes the locking block 7 into the locking groove 10, thus achieving the initial fixation of the housing 1 and the mounting frame 5. Next, rotate the knob 13. The knob 13 drives the threaded rod 11 to rotate. Since one sleeve of the slider 14 is threadedly connected to the threaded rod 11, and the other two sleeves are sleeved on the guide post 12, the guide post 12 restricts the rotation of the slider 14. The rotation of the threaded rod 11 causes the slider 14 to rotate along the guide post 12. Move the slider 14 to the column 12 and precisely adjust its position by controlling the rotation direction and angle of the knob 13, so that the slot 10 and the block 7 can fit together more tightly, enhancing the stability of the connection between the housing 1 and the mounting frame 5. Then, when installing the antenna 3, insert the bottom connecting column of the antenna 3 into the mounting hole on the top surface of the housing 1. At this time, the expansion plate 15 is in a contracted state. After the connecting column is fully inserted into the mounting hole, push the abutment ring 18 downward. The abutment ring 18 drives the expansion column to move down. The expansion column opens up multiple expansion plates 15, so that the protrusion 17 at the lower end of the expansion plate 15 is inserted into the groove 16 in the mounting hole, realizing a firm connection between the antenna 3 and the housing 1. When disassembling, reverse the above steps to quickly complete the disassembly. At this point, the device is in use.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
