[0002] In the fields of communication, surveying, and emergency command, portable antenna equipment is a key component for signal transmission and reception, and its portability and ease of use directly affect operational efficiency. Traditional portable antenna equipment typically consists of an antenna body, a support structure, and adjustment components. The support structure often adopts a tripod form that can be unfolded / folded—three support legs unfold outward to form a stable support. When in use, it is unfolded to a preset angle and fixed by a locking mechanism (such as knobs, buckles, etc.). When folding it up, the support legs must be manually folded towards the center and then secured with straps, storage bags, or other auxiliary tools to prevent the support legs from accidentally coming apart during transportation or storage.

[0003] Traditional tripod legs need to be manually folded and aligned one by one, and to prevent them from unfolding after storage, the overall structural length cannot be changed after storage. In addition, existing foldable storage legs use multiple linkages to connect the support legs and support rods, making the structure relatively more complex. Utility Model Content

[0006] Furthermore, the inner wall of the sleeve is provided with several protruding ridges, and the bottom end of the sleeve is provided with an annulus. The outer surface of the annulus seat is provided with multiple sliding grooves and multiple limiting grooves. The sliding grooves and limiting grooves are distributed at intervals, and the protruding ridges cooperate with the sliding grooves or limiting grooves.

[0007] Furthermore, the base includes a column and a disc connected to the end of the column. The column extends into the stepped hole in the middle of the ring seat and is installed with a nut. The disc has a protrusion opposite to the column. Multiple hinge seats are provided on the outer side of the protrusion. The end of the support leg is installed on the hinge seat.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the fields of communication, surveying, and emergency command, portable antenna equipment is a key component for signal transmission and reception, and its portability and ease of use directly affect operational efficiency. Traditional portable antenna equipment typically consists of an antenna body, a support structure, and adjustment components. The support structure often adopts a tripod form that can be unfolded / folded—three support legs unfold outward to form a stable support. When in use, it is unfolded to a preset angle and fixed by a locking mechanism (such as knobs, buckles, etc.). When folding it up, the support legs must be manually folded towards the center and then secured with straps, storage bags, or other auxiliary tools to prevent the support legs from accidentally coming apart during transportation or storage.

[0027] Please see Figures 1-6 As shown, this utility model is a portable antenna device, including a rod-shaped structure.

[0028] The rod-shaped structure includes a sleeve 1 and an extension rod 2 connected in sequence. The sleeve 1 is connected to a retractable base, and a connector 10 is installed on the extension rod 2.

[0029] The extension rod 2 has a lower seat 201 sleeved on the sleeve 1 and an upper seat 202 connected to the connector 10 at both ends;

[0030] Connector 10 is an RF coaxial connector.

[0031] The sleeve 1 and extension rod 2 are made of PVC or ABS material and are vertically installed in a rod-like structure. The upper end of the sleeve 1 is provided with external thread, and the lower seat 201 is provided with internal thread. The lower seat 201 is fitted and installed on the upper end of the sleeve 1 through thread engagement. After installation, the extension rod 2 is located above the sleeve 1.

[0032] The base includes a ring seat 3 located inside the sleeve 1 and a base 4 connected to the bottom end of the ring seat 3;

[0033] The inner wall of the sleeve 1 is provided with several protruding ribs 101, and the bottom end of the sleeve 1 is provided with a ring body 102. The outer surface of the ring seat 3 is provided with multiple sliding grooves 301 and multiple limiting grooves 302. The sliding grooves 301 and the limiting grooves 302 are distributed at intervals, and the protruding ribs 101 cooperate with the sliding grooves 301 or the limiting grooves 302.

[0034] The base 4 is connected to multiple support legs 6. There are three support legs 6. When the three support legs 6 are retracted, they extend into the inside of the sleeve 1.

[0035] The base 4 includes a column 401 and a disc 402 connected to the end of the column 401. The column 401 extends into the stepped hole in the middle of the ring seat 3 and is installed with a nut 5. The disc 402 is provided with a protrusion 403 opposite to the column 401. Multiple hinge seats 404 are provided on the outer side of the protrusion 403. The end of the support leg 6 is installed on the hinge seat 404. The support leg 6 is provided with a chamfered structure 602 that contacts the disc 402.

[0036] Among them, there are three sliding grooves 301 and three limiting grooves 302, and three protruding ribs 101. The protruding ribs 101 are distributed along the axial direction of the sleeve 1, while the sliding grooves 301 and the limiting grooves 302 are distributed along the axial direction of the ring seat 3.

[0037] When the three support legs 6 need to be unfolded, pull the sleeve 1. The protrusion 101 inside the sleeve 1 slides along the slide groove 301 until the protrusion 101 disengages from the slide groove 301. Rotate the ring seat 3, the base 4, and the three support legs 6. After rotating 30°, the limiting groove 302 is aligned with the protrusion 101. Then, push the rotating ring seat 3 to extend into the sleeve 1, so that the end of the protrusion 101 extends into the limiting groove 302 until the end of the limiting groove 302 contacts the end of the limiting groove 302, thus separating the three support legs 6 to achieve support.

[0038] After the support leg 6 rotates, the chamfered structure 602 contacts the disc body 402, thus limiting the rotation of the support leg 6.

[0039] A magnet 601 is provided at the bottom of the support leg 6, and the magnet 601 is magnetically attracted to the ring 102.

[0040] When storing, the three support legs 6 are joined together, and the sleeve 1 is pushed onto the joined three support legs until the magnet 601 and the ring 102 are magnetically attracted to each other, so as to form a rod shape for storage.

[0041] In addition, when the entire structure is lifted, the three supporting legs 6 close together under the action of gravity.

[0042] This solves the problem that traditional tripods require the support legs to be manually folded and aligned one by one, and that the overall structural length cannot be changed after storage to prevent them from falling apart.

[0043] The lower body 201 is provided with multiple connecting seats 203, and a folding rod 7 is connected to the connecting seat 203. Multiple metal rods 9 are connected to the folding rod 7.

[0044] In addition, the metal rod 9 can be vertically installed by installing a connecting seat 203 on the vertical side of the lower seat 201.

[0045] The folding rod 7 has multiple slots 701, and a mounting base 8 is installed on the slot 701. At the same time, the metal rod 9 is inserted into the mounting base 8.

[0046] The extension rod 2 has a hollow structure, and a through groove 204 communicating with the hollow structure is opened on the outside of the extension rod 2.

[0047] When in use, flip the folding rod 7 downwards and insert the metal rod 9 into the round hole provided on the snap-fit ​​seat 8. When storing, pull out the metal rod 9 to store it.
