[0031] Embodiment 1: An outdoor shortwave receiving device with stable installation, including a support base 1 and a support column 5. A second double-sided threaded rod 11 is rotatably connected to the inner wall of the support base 1. Second clamping blocks 15 are threadedly connected to both the left and right sides of the outer wall of the second double-sided threaded rod 11.

A spring 16 is fixedly connected to the rear end of the clamping block 17. The rear end of the spring 16 is fixedly connected to the inner wall of the telescopic rod 6. A turntable 8 is slidably connected to the top end of the telescopic rod 6. Limiting frames 22 are fixedly connected to both the front and rear sides of the top end of the turntable 8. The front and rear sides of a toothed plate 25 are respectively slidably connected to the opposite ends of the limiting frames 22. A bracket 18 is fixedly connected to the top end of the turntable 8.

The shape and size of the front end of the clamping block 17 are in conformity with the shape and size of the slots.

[0032] As Figure 1 、 Figure 3 and Figure 4 shown, first place the support base 1 on the ground, insert the fixing nails 2 into the ground where the support base 1 is placed to provide a limiting force, then install the support column 5 on the support base 1, rotate the double-sided threaded rod, so as to realize that the clamping blocks on the four sides are retracted into the groove 3, thereby fixing the support base 1 on the support base 1. Push the clamping block 17 into the telescopic rod 6 and lift it upward, thereby lifting the receiving device. After raising it to the optimal height, align the clamping block 17 with the slot on the support column 5. At this time, the clamping block 17 will move outward under the reaction force of the spring 16 and be stuck into the slot to limit the movement of the telescopic rod 6. Adjust the turntable 8 to adjust the angle of the receiving device, and open the limit on the turntable 8 to adjust the tilt angle of the receiving device.

[0033] Embodiment 2: A worm gear 13 is threadedly connected to the bottom end of the outer wall of the worm 12. A first double-sided threaded rod 10 is fixedly connected to the inner wall of the worm gear 13. The front and rear sides of the first double-sided threaded rod 10 are respectively rotatably connected to the front and rear sides of the inner wall of the support base 1. The inner walls of the first clamping blocks 14 are respectively threadedly connected to the front and rear sides of the outer wall of the first double-sided threaded rod 10. A regulating rod 4 is rotatably connected to the left end inner wall of the support base 1. The right end of the regulating rod 4 is fixedly connected to the left end of the second double-sided threaded rod 11. The outer walls of the second clamping blocks 15 are respectively slidably connected to the left and right side inner walls of the support base 1. Grooves 3 are evenly formed on the four sides of the bottom end of the support column 5. The opposite sections of the second clamping blocks 15 and the opposite sections of the first clamping blocks 14 are all in conformity with the grooves 3 in terms of shape and size.

[0034] As Figure 1 and Figure 2 shown, for disassembling the groove 3 from the support base 1, first rotate the regulating rod 4 clockwise. The regulating rod 4 will drive the second double-sided threaded rod 11 to rotate, thereby driving the worm 12 to rotate together, and will drive the worm gear 13 connected to the worm 12 and the first double-sided threaded rod 10 connected thereto to rotate. At this time, the worm 12 will drive the second double-sided threaded rod 11 to expand outwards, and the first double-sided threaded rod 10 will drive the first clamping blocks 14 to expand outwards, so as to release the restriction of the support base 1 on the groove 3. At this time, the groove 3 can be taken off from the support base 1.

[0035] Embodiment 3: A first knob 7 is fixedly connected to the front end of the first threaded rod 19. A slide plate 24 is slidably connected to the inner wall of the fixing plate 21. A second threaded rod 23 is rotatably connected to the top end of the fixing plate 21. A second knob 26 is fixedly connected to the top end of the second threaded rod 23. The bottom end of the slide plate 24 is slidably connected to the front side of the top end of the turntable 8. The rear end of the slide plate 24 is a bevel with a certain angle.

[0036] As Figure 3 、 Figure 4 and Figure 5 shown, the toothed plate 25 will contact the bevel of 24 and slide above the limiting frame 22 without contacting the turntable 8. When adjusting the orientation and tilt angle of the short-wave receiver 9, rotate the turntable 8 and indirectly drive the short-wave receiver 9 to rotate so as to adjust the orientation. When adjusted to the optimal orientation, rotate the first knob 7 to drive the first threaded rod 19 to move inwards and tightly adhere to the telescopic rod 6, thereby restricting the rotation of the turntable 8. At this time, the orientation is fixed. Then, adjust the tilt angle between the short-wave receiver 9 and the turntable 8 to obtain the optimal receiving position. When the adjustment is completed, push in the slide plate 24. The bevel of the slide plate 24 will squeeze the toothed plate 25, thereby moving the toothed plate 25 upwards along the limiting frame 22 and driving the toothed plate 25 to move upwards. When the toothed plate 25 moves and engages with the gear 20, stop the movement of the slide plate 24 and rotate the second knob 26 to move the second threaded rod 23 downwards and press the slide plate 24 tightly to make it in a fixed state, and the adjustment of the short-wave receiver 9 is completed.

[0037] Working principle: Place the support base 1 on the ground, hammer the fixing nails 2 into the ground through the openings on the support base 1, place the support column 5 on the support base 1, rotate the adjusting rod 4, the adjusting rod 4 will drive the second double-sided threaded rod 11 to rotate, thus driving the worm 12 to rotate together. At this time, it will drive the worm gear 13 and the first double-sided threaded rod 10 connected to it to rotate. At this time, the worm 12 will drive the second double-sided threaded rod 11 to contract inward, and the first double-sided threaded rod 10 drives the first clamping block 14 to contract inward. When the first clamping block 14 enters the groove 3 under the support column 5 and clamps the support column 5, at this time, the support column 5 will be fixed on the support base 1 and have strong stability with the indirect cooperation of the fixing nails 2. It realizes that the bottom of the device is provided with a detachable fixing device and there are multiple nails for auxiliary fixing, enabling it to have strong wind resistance during outdoor work, enabling it to receive signals stably, improving the stability of the device, thereby improving the communication quality and efficiency of the device. Then adjust the height of the telescopic rod 6, press the block 17 into the spring 16. At this time, the spring 16 will lose the fixation between the support column 5 and the telescopic rod 6. Lift the telescopic rod 6 to the optimal position and ensure that the block 17 is aligned with the opening on the support column 5. The block 17 will move outward under the reaction force of the spring 16 and snap into the opening on the support column 5, thus obtaining the limit between the support column 5 and the telescopic rod 6. At this time, the height will be fixed. Rotate the turntable 8 and indirectly drive the short-wave receiver 9 to rotate to adjust the orientation. When adjusted to the optimal orientation, rotate the first knob 7 to drive the first threaded rod 19 to move inward and tightly stick to the telescopic rod 6, thus restricting the rotation of the turntable 8. At this time, the orientation fixation is completed. Then adjust the inclination angle between the short-wave receiver 9 and the turntable 8 to obtain the optimal receiving position. When the adjustment is completed, push the slide plate 24. The inclined surface of the slide plate 24 will squeeze the toothed plate 25, thus moving the toothed plate 25 upward along the limit frame 22 and driving the toothed plate 25 to move upward. When the toothed plate 25 moves and engages with the gear 20, stop the movement of the slide plate 24 and rotate the second knob 26 to move the second threaded rod 23 downward and press the slide plate 24 tightly. At this time, the slide plate 24 will be restricted from moving. At this time, the adjustment of the short-wave receiver 9 is completed. It realizes that the device can adjust the receiving device in multiple directions, enabling it to find the optimal signal receiving position by rotating the receiving device outdoors, ensuring the continuity and stability of communication. In addition, rotating the receiving device also helps to receive signals in the full frequency band, improving the sensitivity and accuracy of signal reception.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
