[0061] A specific embodiment of the present invention discloses an installation device for a VHF radio receiving antenna, such as Figure 1 、 Figure 3 and Figure 4As shown, it includes an antenna mounting base assembly 100, a limit connection assembly 200, and a lifting assembly 300; the antenna fixing base assembly 100 includes a connecting piece 110 with a fixing hole; the limit connection assembly 200 includes a first unit 210 and a second unit 220; the first unit 210 includes a first mounting box 211 and a limit hole 212 provided on the first mounting box 211; the second unit 220 includes a plug-in piece 221; the lifting assembly 300 includes a screw rod 310 and a sleeve 320; the connecting piece 110, the first mounting box 211, and the screw rod 310 are connected in sequence from top to bottom; by passing the plug-in piece 221 through the fixing hole and the limit hole 212, the connection between the first mounting box 211 and the connecting piece 110 is completed; by rotating the sleeve 320, the screw rod 310 screwed to the sleeve 320 makes a reciprocating up and down movement, and the lifting of the antenna fixing base assembly 100 is completed.

[0062] In this embodiment, on the one hand, through the setting of the connecting piece 110 and the first mounting box 211, the antenna fixing base assembly 100 is placed in the first mounting box 211; on the other hand, through the setting of the fixing hole, the limit hole 212, and the plug-in piece 221, the detachable connection between the connecting piece 110 and the first mounting box 211 is realized, and further the plug-in limit connection between the antenna fixing base assembly 100 and the first mounting box 211 is realized, so as to realize the convenient installation and disassembly of the antenna fixing base assembly 100 and provide convenience for the installation and disassembly of the antenna 500.

[0063] In this embodiment, first, the connecting piece 110, the first mounting box 211, and the screw rod 310 are connected in sequence from top to bottom. Secondly, by rotating the sleeve 320 to drive the screw rod 310 to make a reciprocating up and down movement, and then the connecting piece 110 makes a reciprocating up and down movement along with the screw rod 310, so as to realize that the antenna fixing base assembly 100 drives the antenna 500 mounted thereon to make a reciprocating up and down movement, which is convenient for installing and disassembling the antenna 500 at a low place and eliminates the danger of working at heights.

[0064] Furthermore, considering the installation of the antenna, in this embodiment, the antenna mounting base assembly 100 further includes an antenna fixing base 120 and an antenna mounting groove, as Figure 2 shown, an antenna mounting groove is provided on the upper surface of the antenna fixing base 120 for mounting the antenna 500. The bottom surface of the antenna fixing base 120 is connected to the connecting piece 110 for connecting to the first mounting box 211.

[0065] Furthermore, the limit connection assembly 200 includes a first unit 210 and a second unit 220, as Figure 1 and Figure 3 shown, the first unit 210 and the second unit 220 are connected, and the installation and disassembly of the limit connection assembly 200 and the antenna mounting base assembly 100 are completed through the common action of the first unit 210 and the second unit 220.

[0066] In this embodiment, the first unit 210 includes a first mounting box 211 and limiting holes 212, as Figure 3 shown. The upper end of the first mounting box 211 is detachably connected to the antenna mounting base assembly 100, and the lower end of the first mounting box 211 is connected to the lifting assembly 300.

[0067] Considering the installation of the connecting member 110, the first mounting box 211 is provided with a mounting cavity matching the connecting member 110, and the contour of the mounting cavity matches the outer contour of the connecting member 110.

[0068] Considering the stability of the limit, two limiting holes 212 are provided and are oppositely arranged. The limiting holes 212 are provided on the side wall of the first mounting box 211, as Figure 3 shown. Exemplarily, the first mounting box 211 is a cubic structure with an open upper end and a mounting cavity. The cubic structure includes a first side wall and a second side wall opposite to the first side wall. Limiting holes 212 are respectively provided on the first side wall and the second side wall, and the two limiting holes 212 are oppositely arranged.

[0069] In this embodiment, the connection between the first mounting box 211 and the connecting member 110 is realized through the second unit 220. Specifically, the second unit 220 includes a plug-in member 221, a second mounting box 222 and a pull rod 223, as Figure 3 shown. Among them, the second mounting box 222 is connected to the first mounting box 211, and the second mounting box 222 is connected to the outer surface of the first side wall of the first mounting box 211.

[0070] Considering that the plug-in member 221 needs to move along the central axis direction of the limiting hole 212 during the limiting connection process, the second mounting box 222 includes a cavity for arranging the pull rod 223 and providing a moving space for the plug-in member 221. Through the limiting hole 212, the cavity communicates with the mounting cavity of the first mounting box 211, so as to realize that the pull rod 223 drives the plug-in member 221 to perform a linear reciprocating motion between the cavity and the mounting cavity, thereby realizing the connection and disconnection with the limiting hole 212 and the fixing hole.

[0071] To facilitate the plugging and limiting connection operation of the plug-in member 221, the first end of the pull rod 223 is connected to the plug-in member 221. Specifically, the first end of the pull rod 223 is arranged in the cavity, and the second end of the pull rod 223 passes through the cavity and is connected to the operation handle, which is convenient for the operator to hold, as Figure 3 shown.

[0072] Further, considering the connection stability between the first mounting box 211 and the second mounting box 222, as well as the connection stability of the plug-in member 221, the limiting hole 212 and the fixing hole, the second unit 220 further includes a spring 224, as Figure 3As shown, the spring 224 is disposed within the cavity and sleeved on the pull rod 223, and the spring 224 is disposed between the first end of the pull rod 223 and the inner wall of the second mounting box 222. The spring 224 expands and contracts along the central axis direction of the limiting hole 212. Through the elastic pressure of the spring 224, the stability of the connection between the first mounting box 211 and the second mounting box 222, as well as the stability of the connection between the plug-in member 221, the limiting hole 212, and the fixing hole, are achieved. Among them, the spring 224 is a return spring. Specifically: when the first mounting box 211 is not connected to the connecting member 110, based on the pressure of the spring 224, the plug-in member 221 is connected to the limiting hole 212. When the connecting member 110 is to be connected to the first mounting box 211, first, the spring 224 is compressed by pulling the pull rod 223, thereby driving the plug-in member 221 away from the limiting hole 212; second, the connecting member 110 is placed in the mounting cavity of the first mounting box 211; then, the pull rod 223 is released, and the spring 224 resets, pushing the plug-in member 221 through the limiting hole 212 on the first mounting box 211 and the fixing hole on the connecting member 110; finally, the connection between the connecting member 110 and the first mounting box 211 is completed, thereby realizing the connection between the antenna mounting base assembly 100 and the first mounting box 211. The disassembly process is also achieved through the expansion and contraction of the spring 224.

[0073] Further, considering the controllability of the compression of the spring 224, and thus controlling the moving displacement of the plug-in member 221, the second unit 220 further includes a limiting plate 225, as Figure 3 shown, the limiting plate 225 is disposed between the spring 224 and the plug-in member 221. The spring 224, the first end of the pull rod 223, the limiting plate 225, and the plug-in member 221 are arranged in sequence, and the first end of the pull rod 223, the limiting plate 225, and the plug-in member 221 are connected in sequence. This arrangement avoids the direct contact between the spring 224 and the plug-in member 221 and the limiting hole 212, avoids jamming, and improves the smoothness of the operation of the plug-in member 221.

[0074] Further, considering that the antenna is set at a high place, which is not conducive to installation and maintenance, the installation device of this embodiment is provided with a lifting assembly 300, as Figure 1 and Figure 4 shown, through the lifting assembly 300, the antenna mounting base assembly 100 is raised and lowered, and thus the installation and maintenance of the antenna are completed at a low place, eliminating the dangers and inconvenience in high-altitude operations. Among them, the lifting assembly 300 includes a screw rod 310 and a sleeve 320; the first mounting box 211 is connected to the upper end of the screw rod 310; by rotating the sleeve 320, the screw rod 310 screwed to the sleeve 320 makes a reciprocating up and down movement, thereby driving the first mounting box 211 to make a reciprocating up and down movement, so as to realize the up and down movement of the antenna mounting base assembly 100 connected to the first mounting box 211 and the antenna 500 mounted on the antenna mounting base assembly 100.

[0075] Further, considering the control of the rotation of the sleeve 320, the lifting assembly 300 further includes a driving assembly 330, as Figure 4 shown.

In this embodiment, rotating the rotating rod 331 drives the driving gear 332 to rotate, and then drives the driven gear 333 to rotate, thereby driving the sleeve 320 to rotate. When the axial position of the sleeve 320 remains unchanged, the sleeve 320 rotates, and the screw rod 310 screwed to the sleeve 320 displaces along the axial direction of the sleeve 320, thereby driving the first mounting box 211 to rise and fall, and thus completing the lifting of the antenna fixing base assembly 100.

[0076] Further, considering the convenience of rotating the rotating rod 331, the driving assembly 330 further includes a knob 334, as Figure 4 shown. The knob 334 is connected to the second end of the rotating rod 331.

[0077] Further, considering the support for the screw rod 310, the sleeve 320, and the driving assembly 330, the lifting assembly 300 further includes a support base 340, as Figure 4 shown.

The connecting plate 350 is connected to the top end of the screw rod 310, and through the connecting plate 350, the stable connection between the screw rod 310 and the first mounting box 211 is realized.

[0079] Further, considering the support for the antenna mounting base assembly 100, the limit connection assembly 200, and the lifting assembly 300, the installation device in this embodiment further includes a support assembly 400.

Through holes are provided on the upper support plate 410, and the sleeve 320 passes through the through holes. The sleeve 320 and the through holes do not displace in the direction of the central axis of the sleeve 320.

[0081] Exemplarily, in this embodiment, the upper support plate 410 can also provide fixed support for the screw rod 310, the sleeve 320, and the driving assembly 330. Specifically: The driving gear 332 includes a gear shaft in the middle and a gear on the outside. The gear shaft is connected to the gear.
