[0041] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as they do not conflict with each other.

[0042] Embodiment

[0043] As Figures 1 to 11 shown, the present embodiment provides a fall-resistant communication device, which comprises a box body 1 and a bottom box 8 connected to the bottom of the box body 1. In the present embodiment, the bottom box 8 is bolted to the bottom of the box body 1, and an instrument 10 is connected to the inside of the box body 1. In the present embodiment, the instrument 10 is an information security acquisition communication device main body, which is bolted to the inside of the box body 1. Of course, the aforementioned bolted connection can also be other existing common connection methods, which are not limited herein.

[0044] The box body 1 is in the shape of a regular cuboid, and the height of the box body 1 is greater than the height of the bottom box 8. The two sides of the box body 1 are respectively provided with air cushions 6.

[0045] The bottom box 8 is provided with a trigger structure 7 and a traction structure. The bottom box 8 is provided with an extrusion structure 4 and an air bag 5 located below the extrusion structure 4. The four corners of the bottom of the bottom box 8 are rotatably connected with walking wheels 9, which are used for supporting the bottom box 8 and also facilitate the movement of the box body 1 and the bottom box 8. The air bag 5 is connected to the air cushion 6 through an inflation pipeline. When the box body 1 is tilted to one side, the trigger structure 7 on this side will be hit and moved, and the movement of the trigger structure 7 drives the traction structure to act and in turn drives the extrusion structure 4 to make a downward movement. The extrusion structure 4 extrudes the air bag 5 to inflate the air cushion 6 connected to the air bag 5. The air cushion 6 expands outwardly to the tilted side of the box body 1, and the air cushion 6 abuts against the ground to support the box body 1, thereby buffering and protecting the box body 1 and the instrument inside the box body 1.

[0046] In the present embodiment, the extrusion structure 4 comprises a balance frame 41, a first sliding sleeve 42, a second sliding sleeve 43, a first extrusion rod 44 hinged to the first sliding sleeve 42, and a second extrusion rod 45 hinged to the second sliding sleeve 43. The balance frame 41 is rotatably connected to the bottom box 8 through a rotating shaft. The first sliding sleeve 42 and the second sliding sleeve 43 are respectively slidably sleeved on the balance frame 41 and located on both sides of the rotating shaft of the balance frame 41. Specifically, Figure 2As shown, the first pressing rod 44 is hinged to the rear side of the first sliding sleeve 42, and the second pressing rod 45 is hinged to the rear side of the second sliding sleeve 43. The air bags 5 include a first air bag 51 and a second air bag 52, and the first pressing rod 44 and the second pressing rod 45 are respectively located above the first air bag 51 and the second air bag 52. In the embodiment, the first pressing rod 44 and the second pressing rod 45 are in contact with or even slightly abut against the first air bag 51 and the second air bag 52, so that the time for the first pressing rod 44 to start effectively abutting against the first air bag 51 or the time for the second pressing rod 45 to start effectively abutting against the second air bag 52 is shortened during the tilting of the box 1, and the corresponding air bag 5 is inflated in time by being pressed, the air cushion 6 in communication with the pressed air bag 5 is inflated in time, and the air cushion 6 is inflated outward in time to buffer and support the tilting box 1. Of course, the first pressing rod 44 and the second pressing rod 45 can also not be in contact with the first air bag 51 and the second air bag 52 in the initial state.

[0047] As for the position of the triggering structure 7, the triggering structure 7 can be arranged inside the bottom box 8 or outside the bottom box 8 (for example, Figure 3 As shown, the triggering structure 7 can be arranged vertically (for example, Figure 3 As shown) or horizontally.

[0048] As for the structure of the triggering structure 7, as shown, Figure 2 The triggering structure 7 can be a triggering plate. When the triggering plate is arranged vertically on the bottom box 8, the triggering plate is stopped on the inner bottom wall of the limiting sleeve 74 (not shown in Figure 2 , see Figure 3 ) in the initial state of the box 1. When the box 1 is tilted, the triggering plate on the tilting side is hit by the ground, slides in the limiting sleeve 74 and moves upward. When the triggering plate is arranged horizontally on the bottom box 8, when the box 1 is tilted, the triggering plate on the tilting side is hit by the ground, slides in the limiting sleeve 74 and moves horizontally into the bottom box 8. As shown, Figure 3 Each triggering structure 7 includes an auxiliary wheel base 71, an auxiliary wheel 72 rotatably connected below the auxiliary wheel base 71, and a rack plate 73 connected above the auxiliary wheel base 71. Two limiting sleeves 74 are fixedly connected to the two sides of the bottom box 8. The limiting sleeves 74 can guide the movement of the triggering plate or the rack plate 73, so that the triggering plate or the rack plate 73 in the triggering structure 7 moves stably up and down, and is prevented from being tilted.

[0049] As shown, Figure 3As shown, the trigger structure 7 is two, located on both sides of the bottom box 8, for the convenience of explanation, the two trigger structures 7 are defined as the first trigger structure 7a and the second trigger structure 7b. Of course, the trigger structure 7 can be arranged only on the side of the box body 1 which is easy to be tilted. When the trigger structure 7 is arranged as two, the corresponding traction structure is also two, for the convenience of explanation, the two traction structures are defined as the first traction structure and the second traction structure.

[0050] As the first embodiment, as shown in the figure, Figure 2 As shown, the inner end of the first elastic traction member 32 of the first traction structure and the inner end of the second elastic traction member 33 of the second traction structure are connected to both ends of the balance frame 41 of the extrusion structure 4, of course, the middle part of the balance frame 41 can also extend upward to form a vertical extension, then, the inner end of the first elastic traction member 32 and the inner end of the second elastic traction member 33 are connected to the vertical extension. The outer end of the first elastic traction member 32 is connected to the top end of the first trigger structure 7a through the first guide wheel 232, and the outer end of the second elastic traction member 33 is connected to the top end of the second trigger structure 7b through the second guide wheel 223, and the first guide wheel 232 and the second guide wheel 223 are both located below the extrusion structure 4, in this way, the distance that the first elastic traction member 32 drives the left end of the balance frame 41 to tilt to the lower left or the distance that the second elastic traction member 33 drives the balance frame 41 to tilt to the lower right can be increased, thereby the force that the first extrusion rod 44 extrudes the first air bag 51 or the force that the second extrusion rod 45 extrudes the second air bag 52 is correspondingly increased, to ensure the inflation effect of the air cushion 6. When the box body 1 is tilted to the left side, the first trigger structure 7a is hit by the ground and slides in the limiting sleeve 74 and moves upward, the first elastic traction member 32 will drive the balance frame 41 to tilt to the lower left, correspondingly, the first sliding sleeve 42 which is sleeved on the balance frame 41 slides to the left end of the balance frame 41, driving the first extrusion rod 44 to move downward and extruding the first air bag 51, the air cushion 6 which communicates with the first air bag 51 is inflated, at the same time, the right end of the balance frame 41 is lifted to the upper right, and the second elastic traction member 33 is elongated. In the process of lifting the box body 1, the first trigger structure 7a has a tendency to move downward to the original position, correspondingly, the pulling force of the first trigger structure 7a on the first elastic traction member 32 is weakened, and the balance frame 41 gradually returns to the original position with the traction of the second elastic traction member 33, and the first elastic traction member 32 and the second elastic traction member 33 will also return to the original position. When the box body 1 is tilted to the right side, the principle of cooperation between the second trigger structure 7b, the second traction structure and the extrusion structure 4 is the same as when the box body 1 is tilted to the left side, which will not be described here. Of course, in the first embodiment, the first trigger structure 7a and the second trigger structure 7b can also be arranged transversely.

[0051] As the second embodiment, as shown in the figure, Figure 1 , Figures 3 to 11As shown, the traction structure is not directly connected with the trigger structure 7, but is driven through the transmission structure 2. The trigger structure 7 drives the corresponding traction structure through the corresponding transmission structure 2, and the traction structure drives the extrusion structure 4 to tilt to the corresponding side, thereby extruding the air bag 5 to inflate the air cushion 6 communicated with the air bag 5. In the embodiment, when the number of the trigger structure 7 and the traction structure is two, the number of the transmission structure 2 corresponds to two. Two transmission structures 2 are respectively arranged on both sides of the extrusion structure 4. Each transmission structure 2 includes a large bevel gear 21, a small bevel gear 22 engaged with the large bevel gear 21, a transmission gear 27 engaged with the upper part of the large bevel gear 21, a connecting gear 23 coaxially arranged with the small bevel gear 22, a movable gear 24 engaged with the connecting gear 23 up and down, a winding wheel 25 and a unwinding wheel 26 coaxially arranged with the movable gear 24, and a first guide wheel 28 and a second guide wheel 29 respectively located above the winding wheel 25 and the unwinding wheel 26. The winding wheel 25 and the unwinding wheel 26 are both fixed on the rotating rod 241 of the movable gear 24. The two unwinding wheels 26 are arranged adjacent to the extrusion structure 4, and the outer ends of the first elastic traction member 32 and the second elastic traction member 33 are respectively connected to the upper part of the corresponding winding wheel 25 through the third guide wheel 289 and the fourth guide wheel 298, and the first elastic traction member 32 and the second elastic traction member 33 are both in L-shaped structure. The first elastic traction member 32 and the second elastic traction member 33 are both made of a material with strong elasticity, and are preferably made of rubber material, so as to effectively pull the balance frame 41 to rotate, and because the first elastic traction member 32 and the second elastic traction member 33 are both elastic, the balance frame 41 can be pulled back to the original position. The transmission structure 2 further includes a connecting rod 201 hinged to the upper part of the large bevel gear 21, and a sector gear 20 hinged to the connecting rod 201. The teeth of the sector gear 20 are engaged with the teeth on the rack plate 73 of the trigger structure 7. Specifically, the sector gear 20 is rotatably connected to the notch 81 on the bottom box 8 through a bearing, so that the sector gear 20 can rotate smoothly and avoid shaking. The sector gear 20 is exposed outside the notch 81 of the bottom box 8, so as to be engaged with the rack plate 73 of the trigger structure 7. In the embodiment, part of the sector gear 20 is also located in the bottom box 8. Of course, the trigger structure 7 and the large bevel gear 21 can also be matched through other forms.

[0052] In addition, the teeth of the transmission gear 27 are engaged with the teeth of the stabilizing frame 13, the stabilizing frame 13 is located above the transmission gear 27 and extends out of the bottom box 8, and the transmission gear 27 is located at the top of the bottom box 8. When the box body 1 is tilted to one side, the stabilizing frame 13 is driven by the transmission gear 27 to move outwards to the tilting side of the box body 1, and the stabilizing frame 13 supports the box body 1 in the tilting state. If the box body 1 continues to tilt, the inflated air cushion 6 contacts the ground instead of the box body 1, so as to effectively buffer and protect the box body 1 and the instruments in it. Specifically, when the box body 1 is tilted to one side, the transmission gear 27 drives the stabilizing frame 13 to move outwards to the tilting side of the box body 1, and the stabilizing frame 13 supports the box body 1 in the tilting state. If the box body 1 continues to tilt, the inflated air cushion 6 contacts the ground instead of the box body 1, so as to effectively buffer and protect the box body 1 and the instruments in it. Figure 3In the perspective view, the stabilizer 13 is in L-shaped structure, and is in sliding cooperation with the bottom box 8 through the slide rail, so that the stabilizer 13 can slide horizontally stably, and the inner sides of the two stabilizers 13 abut against each other, and the outer ends of the two stabilizers 13 are located outside the bottom box 8. The stabilizer 13 is in L-shaped structure, including a horizontal sliding part and a vertical limiting part. The vertical limiting part cooperates with the inner wall of the bottom box 8 to limit the stabilizer 13, so as to avoid that the stabilizer 13 is completely slid out of the bottom box 8.

[0053] In the second embodiment, the trigger structure 7 is connected to the outer side of the bottom box 8 and extends towards the box body 1. The box body 1 is tilted to one side, and the trigger structure 7 at this side is impacted, slides in the limiting sleeve 74 fixedly connected to the bottom box 8 and moves upward. The trigger structure 7 includes an auxiliary wheel base 71, an auxiliary wheel 72 rotatably connected below the auxiliary wheel base 71, and a rack plate 73 connected above the auxiliary wheel base 71. In the vertical direction, the bottom of the auxiliary wheel 72 is not lower than the bottom of the walking wheel 9 installed at the bottom of the bottom box 8. In this embodiment, the bottom of the walking wheel 9 and the bottom of the auxiliary wheel 72 are at the same horizontal plane. The auxiliary wheel 72 and the auxiliary wheel base 71 cooperate to support the rack plate 73 during the movement of the bottom box 8, so as to avoid that the rack plate 73 directly contacts the ground, avoid the friction between the rack plate 73 and the ground, and prolong the service life of the rack plate 73. In addition, since the bottom of the auxiliary wheel 72 and the bottom of the walking wheel 9 are at the same horizontal plane, the auxiliary wheel 72 can be abutted by the ground in time during the tilting of the box body 1, thereby driving the rack plate 73 to move upward. In addition, during the process of supporting the box body 1, the auxiliary wheel 72 can rely on its own gravity to pull the corresponding rack plate 73 back to the original position quickly. Of course, the auxiliary wheel 72 can also not be provided, so that the rack plate 73 abuts against the inner bottom wall of the limiting sleeve 74 fixed to the bottom box 8, and the end of the corresponding rack plate 73 is impacted by the ground during the tilting of the box body 1, and then slides upward in the limiting sleeve 74.

[0054] In the second embodiment, each traction structure further includes a winding belt 31, each winding belt 31 crosses the rotating shaft 271 of the transmission gear 27, and the two ends of each winding belt 31 are wound on the winding wheel 25 and the unwinding wheel 26 in opposite directions through the first guide wheel 28 and the second guide wheel 29. The first guide wheel 28 and the second guide wheel 29 are rotatably arranged on the bottom box 8 through bearings, so that the first guide wheel 28 and the second guide wheel 29 can rotate stably. In this embodiment, the winding belt 31 is cut from a belt.

[0055] In the second embodiment, the balance frame 41 comprises a horizontal extension and a vertical extension, the horizontal extension is hinged to the inside of the bottom box 8, and the inner end of the first elastic traction member 32 and the inner end of the second elastic traction member 33 are both connected to the vertical extension.
