Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of walkie - talkies, and particularly relates to a waterproof and anti - fall walkie - talkie. Background Art
[0002] A walkie - talkie is a terminal device for trunking communication. It can not only be used as a terminal device for trunking communication, but also as a professional wireless communication tool in mobile communication. The walkie - talkie is not restricted by the network. In places where the network is not covered, the walkie - talkie allows users to communicate easily. The walkie - talkie provides one - to - one and one - to - many call modes. Press - to - talk, with simple operation, making communication more free. Especially in the cases of emergency dispatch and collective collaborative work, these features are very important. At the same time, its call cost is low and it is convenient to use.
[0003] Although the above - mentioned prior art can solve corresponding technical problems, there are still certain defects: when the existing walkie - talkie is in use, if it accidentally falls from a height, since there are a large number of precision circuit board components inside the walkie - talkie, when it falls and contacts the floor, it is easy for the impact force generated by the fall to be applied to the surface of the walkie - talkie, causing violent shaking inside it, and transmitting the impact force through the outer shell. As a result, the precision components inside the walkie - talkie become loose or damaged, and its anti - fall performance is poor. It is easy to be damaged when it falls. And if the falling position has accumulated water, it is very easy for some of the accumulated water to enter the walkie - talkie, causing a short - circuit inside it and making it even easier for the walkie - talkie to be damaged. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a waterproof and anti - fall walkie - talkie with strong anti - fall ability and not easy to be damaged in view of the defects and deficiencies of the prior art.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions: a waterproof and anti - fall walkie - talkie, including a body and a talk port arranged on the front surface of the body. The body includes an outer shell and a circuit structure arranged inside the outer shell on the back. The outer wall of the circuit structure is coated with a waterproof bag. The side wall of the outer shell is penetrated with a side pressure block that fits the side wall of the circuit structure. The bottom of the outer shell is penetrated with a drain pipe. The bottom of the inner wall of the drain pipe is provided with a blocking net. The inner wall of the drain pipe is provided with a shrinking block. A light ball that can freely roll and block the shrinking block is arranged between the bottom of the blocking net and the shrinking block on the inner wall of the drain pipe. When the walkie - talkie falls, the side pressure block absorbs excessive impact, and the water entering is discharged unidirectionally through the cooperation of the drain pipe, the shrinking block and the light ball.
[0006] Further improvement is: an antenna is arranged on the top of the body.
[0007] Further improvement is: a display board is arranged on the front of the body.
[0008] Further improvement: A control panel is provided on the front of the body.
[0009] Further improvement: Hollow elliptical balls made of rubber material are provided on both the upper and lower surfaces of the inner wall of the outer casing.
[0010] Further improvement: A slot is provided on the inner wall of the outer casing, and a slider slidably connected to the slot is provided at the rear side of the circuit structure.
[0011] Further improvement: The side pressing block includes a wind pressure pipe penetrating through the side wall of the outer casing and a deformation ball provided at the end of the wind pressure pipe with its outer wall fitting against the side wall of the circuit structure.
[0012] Further improvement: A flow dividing piece is provided in the wind pressure pipe, a rotating shaft is movably clamped on the inner wall of the wind pressure pipe, and a plurality of resistance pieces are provided on the outer wall of the rotating shaft which can fit against and slide on the inner wall of the wind pressure pipe and the surface of the flow dividing piece.
[0013] Further improvement: An inner core is provided on the inner wall of the deformation ball, and an extrusion piece is provided between the outer wall of the inner core and the inner wall of the deformation ball.
[0014] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: When the present utility model drops, the impact generated will pass through the side pressing block provided beside the circuit structure, and then the deformation ball of the side pressing block will deform to absorb the impact. At the same time, the resistance pieces are used to prevent the gas in the deformation ball from being discharged too quickly outward, providing buffering and additional supporting performance, avoiding the circuit structure from swinging rapidly and being damaged, thereby reducing the impact of the impact generated during dropping on the circuit structure. At the same time, if the walkie-talkie gets water, it can be discharged through the drain pipe, and in cooperation with the lightweight ball and the shrinkage block, the water that enters can only be discharged and cannot flow back, and in cooperation with the waterproof bag outside the circuit structure, the waterproof effect is effectively improved, making the walkie-talkie less likely to be damaged when dropped.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Refer to Figures 1-3As shown in the figure, the technical solution adopted in this specific embodiment is as follows: a waterproof and anti-drop walkie-talkie, including a body 1 and a walkie-talkie port 5 provided on the front surface of the body 1. The body 1 includes an outer casing 11 and a circuit structure 12 provided inside the outer casing 11 on the back. The outer wall of the circuit structure 12 is coated with a waterproof bag. A side pressure block 14 that penetrates and fits with the side wall of the circuit structure 12 is provided on the side wall of the outer casing 11. The side pressure block 14 includes a wind pressure pipe 22 that penetrates through the side wall of the outer casing 11 and a deformation ball 21 provided at the end of the wind pressure pipe 22 with its outer wall fitting with the side wall of the circuit structure 12. A drain pipe 15 penetrates through the bottom of the outer casing 11. A blocking net 18 is provided at the bottom of the inner wall of the drain pipe 15. A shrinkage block 16 is provided on the inner wall of the drain pipe 15. A light ball 17 that can freely roll and block the shrinkage block 16 is provided between the blocking net 18 and the bottom of the shrinkage block 16 on the inner wall of the drain pipe 15. When the walkie-talkie falls, the side pressure block 14 absorbs excessive impact and discharges the water that enters unidirectionally through the drain pipe 15 in cooperation with the shrinkage block 16 and the light ball 17. When in use, a signal wave is emitted outward through the circuit structure 12. At this time, the sound is input to the body 1, so that the sound penetrates the outer casing 11 and is received by the circuit structure 12 and then converted into a signal wave and emitted outward to achieve the effect of outputting voice. At the same time, by receiving the external signal through the circuit structure 12 and converting it into sound, the effect of receiving voice can be achieved. When the walkie-talkie accidentally falls, it will cause the outer casing 11 to be strongly impacted, and the impact will be transmitted to the internal circuit structure 12 inside it. At the same time, the outer casing 11 will deform and squeeze the circuit structure 12. At this time, a relative displacement will occur between the circuit structure 12 and the side pressure block 14 provided on the side wall of the outer casing 11, thereby causing the circuit structure 12 to squeeze the side pressure block 14, and then causing the deformation ball 21 of the side pressure block 14 to deform. At this time, the air inside it will be pushed and squeezed to the wind pressure pipe 22. Since the inner diameter of the wind pressure pipe 22 is smaller than that of the deformation ball 21, the outflow speed of the air flow is greatly reduced. Thus, a certain air pressure is maintained in the inner cavity of the deformation ball 21, and after absorbing the pressure when being squeezed, the air is slowly discharged. At this time, the slowly deformed deformation ball 21 can provide support to prevent the circuit structure 12 from directly colliding with the outer casing 21 and causing damage, and at the same time absorb the inertial force generated by the fall, thereby making the circuit structure 12 more stable inside the outer casing 11 and preventing excessive inertia from being applied to the circuit structure 12 and causing damage. At the same time, if the outer casing 11 is damaged and water enters after the fall, then after picking up the walkie-talkie, make the drain pipe 15 face downward, so that the water flows downward. At the same time, cooperate with the waterproof bag to isolate the circuit structure 12. After the water flows downward, it can push the light ball 17 that fits on the shrinkage block 16 to move, thereby making the light ball 17 no longer fit on the shrinkage block 16, and then discharging the accumulated water. And after the fall, if the accumulated water tries to backflow, it will push the light ball 17, making it block on the shrinkage block 16, thereby preventing the accumulated water from entering and preventing the accumulated water from entering the outer casing 11 through the drain pipe 15 after the fall, making the walkie-talkie less likely to be damaged when it falls;
[0021] An antenna 2 is provided at the top of the body 1, which is beneficial to making the intensity of signal reception and transmission higher;
[0022] A display panel 3 is provided on the front of the body 1, which is beneficial to observing walkie-talkie data such as battery power;
[0023] A control panel 4 is provided on the front of the body 1, which is beneficial to more conveniently controlling the walkie-talkie;
[0024] Hollow elliptical balls 13 made of rubber are provided on the upper and lower inner walls of the outer casing 11, which is beneficial to buffering the upper and lower sides of the circuit structure 12 through the elliptical balls 13 after the walkie-talkie drops, making it less likely to be damaged;
[0025] A slot is provided on the inner wall of the outer casing 11, and a slider 19 slidably connected to the slot is provided at the rear of the circuit structure 12, which is beneficial to enabling the circuit structure 12 to move up and down along the slot in cooperation with the slider 19, and thus better offsetting the inertia from the up and down directions and being less likely to be damaged;
[0026] A flow dividing piece 23 is provided in the air pressure pipe 22, a rotating shaft 24 is movably clamped on the inner wall of the air pressure pipe 22, and a plurality of resistance pieces 25 that can be attached to and slide on the inner wall of the air pressure pipe 22 and the surface of the flow dividing piece 23 are provided on the outer wall of the rotating shaft 24. After the gas is pressed into the air pressure pipe 22 due to pressure, it is divided by the flow dividing piece 23 and impacts the resistance pieces 25, so that the resistance pieces 25 rotate along the rotating shaft 24 and slowly release the gas. At the same time, the impact force generated by the gas absorbing pressure will become the driving force for the rotation of the resistance pieces 25 and be offset, thereby further improving the elastic support effect of the deformation ball 21. At the same time, the pressure of the deformation ball 21 can be converted into the rotational driving force of the resistance pieces 25 through the air flow, so as to better absorb the pressure and further avoid the circuit structure 12 being damaged due to inertia;
[0027] An inner core 26 is provided on the inner wall of the deformation ball 21, and an extrusion piece 27 is provided between the outer wall of the inner core 26 and the inner wall of the deformation ball 21, which is beneficial to improving the support performance of the deformation ball 21 and preventing the deformation ball 21 from directly collapsing and causing the circuit structure 12 to collide with the outer casing 11.
[0028] Working principle of the present utility model: When the present utility model is in use, it emits signal waves outward through the circuit structure 12. At this time, sound is input into the body 1, enabling the sound to penetrate the outer housing 11 and be received by the circuit structure 12 and then converted into signal waves and emitted outward to achieve the effect of outputting voice. At the same time, by receiving external signals through the circuit structure 12 and converting them into sound, the effect of receiving voice can be achieved. When the walkie-talkie accidentally drops, it will cause the outer housing 11 to be strongly impacted, and the impact will be transmitted to the internal circuit structure 12 inside it. At the same time, it will cause the outer housing 11 to deform and squeeze the circuit structure 12. At this time, it will cause a relative displacement between the circuit structure 12 and the side pressure block 14 provided on the side wall of the outer housing 11, thereby causing the circuit structure 12 to squeeze the side pressure block 14, and then causing the deformation ball 21 of the side pressure block 14 to deform. At this time, the air inside it will be pushed and squeezed to the air pressure pipe 22. Since the inner diameter of the air pressure pipe 22 is smaller than that of the deformation ball 21, the outflow speed of the air flow is greatly reduced. Thus, a certain air pressure is maintained in the inner cavity of the deformation ball 21, and when it is squeezed, it absorbs the pressure and slowly discharges the air. At this time, the slowly deforming deformation ball 21 can provide support to prevent the circuit structure 12 from directly hitting the outer housing 21 and causing damage, and at the same time absorb the inertial force generated by the fall, thereby making the circuit structure 12 more stable inside the outer housing 11 and preventing excessive inertia from being applied to the circuit structure 12 and causing damage. At the same time, if the outer housing 11 is damaged and water enters after the fall, then after picking up the walkie-talkie, make the drain pipe 15 face downward, thereby making the water flow downward. At the same time, cooperate with the waterproof bag to isolate the circuit structure 12. After the water flows downward, it can push the light ball 17 attached to the shrinkage block 16 to move, thereby making the light ball 17 no longer adhere to the shrinkage block 16, and then discharging the accumulated water. And after the fall, if the accumulated water tries to backflow, it will push through the light ball 17 and block it on the shrinkage block 16, thereby preventing the accumulated water from entering and preventing the accumulated water from entering the outer housing 11 through the drain pipe 15 after the fall, making the walkie-talkie less likely to be damaged when it drops.
