DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0029] Embodiment one: refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , a telephone with anti-falling function, comprising a main body 1 and a microphone 2, the upper end surface of the main body 1 is provided with a placing groove, the microphone 2 is installed in the placing groove, and the main body 1 and the microphone 2 are connected through a telephone line 3. The lower end of the main body 1 is fixed with a supporting leg.

[0030] Refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the center of the lower end surface of the main body 1 is provided with a suction cup 4, and the suction cup 4 is connected with a suction assembly 5 through a communication pipe 6. The communication pipe 6 is a negative pressure resistant hose.

[0031] The suction assembly 5 comprises an outer drum 501 fixed on one side of the main body 1. An inner core 503 is rotatably and sealingly connected in the outer drum 501. The end of the inner core 503 away from the main body 1 extends to the outside of the outer drum 501. A square rod 504 is slidingly arranged in concentric with the side of the inner core 503 away from the main body 1. A rotating sleeve 502 is fixedly arranged on the square rod 504 in concentric. The rotating sleeve 502 is spline connected with the outer drum 501. Anti-skid lines are processed on the outer edge of the rotating sleeve 502. When the rotating sleeve 502 is separated from the outer drum 501, the rotating sleeve 502 can make the inner core 503 rotate through the square rod 504.

[0032] The outer edge of the inner core 503 in the outer drum 501 is fixed with a rotating plate 5031, and the rotating plate 5031 is rotatably and sealingly connected with the inner edge of the outer drum 501. The inner edge of the outer drum 501 is fixed with a fixed plate 5011, and the fixed plate 5011 is rotatably and sealingly connected with the outer edge of the inner core 503. An air suction cavity 8 and an air exhaust cavity 9 are formed between the rotating plate 5031 and the fixed plate 5011. The inside of the suction cup 4 is communicated with the air suction cavity 8 through the communication pipe 6. Air holes 7 are formed on the outer drum 501, and the air holes 7 are communicated with the air exhaust cavity 9.

[0033] Place the main body 1 on the desktop, then press the main body 1, so that the supporting leg of the main body 1 tightly abuts against the desktop, then move the rotating sleeve 502 away from the outer drum 501. When the rotating sleeve 502 is separated from the outer drum 501, the inner core 503 can be rotated through the rotating sleeve 502 and the square rod 504. When the inner core 503 rotates, the rotating plate 5031 rotates, the volume of the air suction cavity 8 increases, the air in the suction cup 4 enters the air suction cavity 8 through the communication pipe 6, the volume of the air exhaust cavity 9 decreases, and the air in the air exhaust cavity 9 is exhausted through the air holes 7. When the suction cup 4 is adsorbed to the desktop, the rotating sleeve 502 is spline connected with the outer drum 501, so as to position the inner core 503 and the rotating plate 5031, and prevent the air in the air suction cavity 8 from flowing back to the suction cup 4.

[0034] When the main body 1 needs to be moved, the sleeve 502 is separated from the outer drum 501, the inner core 503 is rotated through the sleeve 502 and the square rod 504, the rotating plate 5031 rotates when the inner core 503 rotates, the volume of the air suction cavity 8 decreases, the air in the air suction cavity 8 enters the suction disc 4, the volume of the air exhaust cavity 9 increases, and the air outside the outer drum 501 enters the air exhaust cavity 9 through the air hole 7. The air in the air suction cavity 8 enters the suction disc 4, the suction force between the suction disc 4 and the table surface decreases, and then the main body 1 can be moved.

[0035] Embodiment two: based on embodiment one, referring to Figures 1-3 As shown in the figure, the sliding ring 403 is fixed at the center of the suction disc 4, the fixed tube 401 is sealingly inserted into the sliding ring 403 and slides in the sliding ring 403, the upper end of the fixed tube 401 is blocked, the upper end of the fixed tube 401 is fixedly connected with the lower end of the main machine, the upper stop ring 402 is fixed on the fixed tube 401 above the sliding ring 403, the lower stop ring 404 is fixed on the fixed tube 401 below the sliding ring 403, and the part of the fixed tube 401 above the upper stop ring 402 is communicated with the communication tube 6.

[0036] When the main body 1 is stably placed on the table surface, the main body 1 is pressed towards the table surface, at this time, the suction disc 4 and the sliding ring 403 are blocked by the upper stop ring 402, when the main body 1 is pressed towards the table surface, the suction disc 4 is compressed, and part of the air in the suction disc 4 is exhausted. When the inner core 503 and the rotating plate 5031 are rotated through the sleeve 502 and the square rod 504 after the sleeve 502 is separated from the outer drum 501, the air in the suction disc 4 is exhausted through the fixed tube 401 and the communication tube 6 into the air suction cavity 8. When the air in the suction disc 4 is exhausted by rotating the inner core 503 and the rotating plate 5031, the suction disc 4 and the sliding ring 403 can move up and down on the fixed tube 401 until the sliding ring 403 is blocked by the lower stop ring. It can be avoided that the resistance of the table surface to the main body 1 and the repulsion between the suction disc 4 and the table surface are repelled, and the air in the suction disc 4 is prevented from being exhausted, which causes the suction disc 4 to fail to be adsorbed to the table surface.

[0037] Embodiment three: based on embodiment one, referring to Figure 1 and Figure 9 As shown in the figure, the telephone line 3 includes a spiral segment 303 and straight segments 304 on both sides of the spiral segment 303, the straight segments 304 on both sides of the spiral segment 303 are fixed with buckles 301, and the two buckles 301 are connected through an elastic band 302. Preferably, the elastic band 302 penetrates the spiral segment 303 of the telephone line 3.

[0038] Because the straight segments 304 on both sides of the spiral segment 303 of the telephone line 3 are connected through the elastic band 302, during the process of moving the microphone 2 to the user's ear when answering the phone, the spiral segment 303 and the elastic band 302 are stretched at the same time, and the normal use of the microphone 2 is ensured.

[0039] When the microphone 2 falls, the movable distance of the microphone 2 is reduced under the elastic action of the elastic band 302, damage of the microphone 2 caused by falling and hitting the ground can be avoided, and the microphone 2 can be effectively protected.

[0040] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
