DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that it is easy for those skilled in the art to implement these embodiments. However, the present invention can also be implemented in various forms, so the present invention is not limited to the embodiments described below.

[0025] like Figure 1 , Figure 2 As shown, a multi-stage stable satellite narrowband communication device comprises four parts: a box 1, a narrowband communicator 2, a stopper 3, and a stable vibration damper 4;

[0026] The box body 1 is a quadrangular prism with a chamber inside, and the upper cover of the box body 1 is connected to the four walls of the box body 1 by means of, but not limited to, a lock, and a handle is provided in the center of the upper cover of the box body 1;

[0027] The narrowband communicator 2 has a display screen and various interfaces and buttons on its front, an array antenna on its top, and a groove at the bottom of the side wall of the narrowband communicator 2;

[0028] The stopper 3 includes: a telescopic support seat 31; a carrying plate and a clamp 32;

[0029] The telescopic support seat 31 is fixedly disposed in the cavity of the box body 1 and is located at the center of the bottom.

[0030] The carrying plate is fixedly mounted on the telescopic support seat 31, and a cross-shaped slide groove is provided on the carrying plate;

[0031] A spring is provided at the bottom of the carrier plate, the spring surrounds the telescopic support seat 31, and the bottom of the spring is fixedly arranged with the bottom surface of the inner cavity of the box body 1;

[0032] The clamps 32 are four in number and are respectively embedded in the cross slots of the carrier plate through movable blocks. The movement of the clamps 32 can be controlled by a hydraulic or electric control device.

[0033] The front end of the clamp 32 is flexible, which can prevent the clamp 32 from causing damage to the narrowband communicator 2 when squeezing it;

[0034] The stable vibration damper 4 includes: an elastic air cushion 41, a compression ring 42, a limiting ring 43, a counterweight block 44, a track 45, and a slider 46;

[0035] The elastic air cushion 41 (made of flexible material, such as rubber, to enhance its buffering effect) is annular and fixedly arranged in the cavity of the box body 1, and can play a buffering role when the narrowband communicator 2 is hit;

[0036] The elastic air cushion 41 is divided into two parts, the upper and lower parts, with the restriction ring 43 as the boundary, and the height of the upper part is flush with the narrowband communicator 2;

[0037] The lower part of the elastic air cushion 41 covers the entire bottom of the box 1 and surrounds the telescopic support seat 31 at the center of the ring;

[0038] The elastic air cushion 41 has a filled lower part and a deflated upper part, and due to the action of the limiting ring 43, the gas flow between the two parts is restricted;

[0039] The compression ring 42 is coaxially arranged with the carrier plate and located at the outer edge of the carrier plate, and can compress the elastic air cushion 41 as the carrier plate descends;

[0040] The limiting ring 43 is movably arranged on the track 45 via a slider 46 and can move along the track 45;

[0041] The limiting ring 43 presses the elastic gas cushion 41 against the side wall of the housing 2 to limit the gas flow in the elastic gas cushion 41;

[0042] The counterweight blocks 44 are four in number and are equidistantly and annularly arranged at the bottom of the restriction ring 43, and can drive the restriction ring 43 to reset after the restriction ring 43 moves;

[0043] The rails 45 are four in number, equidistantly and annularly arranged vertically on the side wall of the box body 1, and are used to limit the movement trajectory of the compression ring 42;

[0044] There are four sliders 46, one end of each slider 46 is equidistantly and annularly fixedly disposed inside the limiting ring 43, and the other end is embedded in each track 45, so that the limiting ring 43 can move along the track 45;

[0045] The working principle of this utility model:

[0046] Before using the utility model, the narrowband communicator 2 is first placed in the center of the box 1, and then the clamp 32 is controlled to move along the slide groove of the carrier plate, so that the clamp 32 is tightly embedded in the groove at the bottom of the narrowband communicator 2, completing the positioning of the narrowband communicator 2, waiting for subsequent use;

[0047] When the narrowband communicator 2 is vibrated by an external force, the carrier plate presses the telescopic support seat 31 and the spring downward to achieve the first stage of buffering. At the same time, the compression ring 42 on the outer edge of the carrier plate applies pressure to the elastic air cushion 41 below it, and the elastic air cushion 41 is compressed, thereby completing the second stage of buffering. Due to the pressure applied by the compression ring 42 at this time, the gas in the lower half of the elastic air cushion 41 pushes the limiting ring 43 under pressure to make it rise along the track 45. The gas in the lower half of the elastic air cushion 41 can enter the upper half, and the upper half of the elastic air cushion 41 expands to fill the gap between the narrowband communicator 2 and the side wall of the box body 1, thereby performing the third stage of buffering. When the external force interference disappears, the limiting ring 43 can be reset under the action of the counterweight block 44 below it and drive the elastic air cushion 41 to reset, thereby achieving buffering and ensuring the stability of the narrowband communicator 2.
