[0002] A walkie-talkie is a portable communication device, usually used for short-range voice communication. It communicates via radio frequencies and does not rely on telephone networks or Internet connections. Therefore, it can still be used normally in environments with no signal coverage or incomplete communication infrastructure.
[0003] Wireless walkie-talkies are equipped with speaker vents. When the wireless walkie-talkies are in use, dust in the external environment can easily enter the inside of the walkie-talkie through the speaker vents. This situation is particularly prone to occur in deserts. Fine particles and sand and dust in the desert environment can easily enter the inside of the walkie-talkie through the speaker vents. Over time, this dust may accumulate on the internal components of the walkie-talkie, such as speakers and circuit boards, causing the speaker vents to be blocked or the sound output to be weakened.
[0004] Therefore, it is necessary to design a wireless intercom to solve the above problems. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figure 1-5 A wireless intercom includes an intercom 1, the intercom 1 having a plurality of speaker ports 2, a slidable sliding plate 3, the side surfaces of the sliding plate 3 being in contact with the side surfaces of the intercom 1, two opposite fixing plates 4 being fixed to the intercom 1, and a plurality of strip-shaped openings 5 being formed on the sliding plate 3;
[0026] The sliding plate 3 is slidably arranged between the two fixed plates 4 through a limiting assembly. The limiting assembly includes two limiting bars 61 and two limiting grooves 62. The two limiting bars 61 are respectively fixed on both sides of the sliding plate 3, and the two limiting grooves 62 are respectively opened on the sides of the two fixed plates 4. The two limiting bars 61 are respectively slidably arranged in the two limiting grooves 62. When the sliding plate 3 moves, the two limiting bars 61 and the two limiting grooves 62 play a role of limiting and guiding the movement of the sliding plate 3, ensuring the stability of the sliding plate 3 during the movement. When the sliding plate 3 moves downward, the several strip openings 5 are staggered with the speaker ports 2, and the sliding plate 3 blocks the several speaker ports 2. At this time, the sliding plate 3 can prevent dust or sand from entering the interior of the intercom 1 through the several speaker ports 2, thereby protecting the intercom 1. In summary, the staff can control the position of the sliding plate 3 to expose or block the speaker ports 2, and prevent dust or sand from entering the interior of the intercom 1 through the several speaker ports 2 when the intercom 1 is not in use;
[0027] The sliding plate 3 and the two fixed plates 4 are jointly provided with a positioning assembly, which includes four card slots 71, four grooves 72, four springs 73, four card blocks 74 and four convex hulls 75. The four card slots 71 are grouped in twos and are respectively opened on the sides of the two fixed plates 4. The four grooves 72 are grouped in twos and are respectively opened on both sides of the sliding plate 3. The four card blocks 74 are respectively slidably set in the four grooves 72. The side surfaces of the card blocks 74 are fitted with the groove walls of the grooves 72. The four springs 73 are respectively set between the four grooves 72 and the four card blocks 74. The four convex hulls 75 are respectively fixed on the four card blocks 74. When the cam 75 is in the shape of a hemispherical structure and the shape of the cam 75 is adapted to the shape of the slot 71, the two cams 75 can be subjected to force and retracted into the corresponding grooves 72 as the sliding plate 3 moves. When the two cams 75 are respectively moved to the two lower slots 71 on the two fixed plates 4, the two blocks 74 will pop out from the corresponding grooves 72 under the action of the corresponding springs 73. At this time, the two cams 75 are respectively inserted into the two lower slots 71 on the two fixed plates 4, and the position of the sliding plate 3 will be fixed.
[0028] The specific working principle of this utility model is as follows:
[0029] When the intercom 1 proposed by the present invention is in use, the plurality of strip-shaped openings 5 are arranged opposite to the plurality of speaker ports 2, such as Figure 1 As described above, at this time, the plurality of speaker ports 2 are in an exposed state, and the staff can transmit and receive sound through the plurality of speaker ports 2. In addition, in this case, the two convex bumps 75 are respectively stuck in the two upper slots 71 on the two fixing plates 4;
[0030] When the intercom 1 is not in use, the staff pulls down the sliding plate 3, and the sliding plate 3 moves downward, which can drive the two convex bumps 75 to move. Since the convex bumps 75 are hemispherical in structure and the shape of the convex bumps 75 matches the shape of the card slot 71, the two convex bumps 75 can be stressed and retracted into the corresponding grooves 72 when following the movement of the sliding plate 3. When the two convex bumps 75 move to the two lower card slots 71 facing the two fixed plates 4, the two card blocks 74 will pop out from the corresponding grooves 72 under the action of the corresponding springs 73. At this time, the two convex bumps 75 are respectively locked in The position of the sliding plate 3 will be fixed in the two lower slots 71 on the two fixing plates 4. When the sliding plate 3 moves downward, the several strip openings 5 are staggered with the speaker ports 2, and the sliding plate 3 blocks the several speaker ports 2. At this time, the sliding plate 3 can prevent dust or sand from entering the interior of the intercom 1 through the several speaker ports 2, thereby protecting the intercom 1. In summary, the staff can control the position of the sliding plate 3 to expose or block the speaker ports 2, and prevent dust or sand from entering the interior of the intercom 1 through the several speaker ports 2 when the intercom 1 is not in use.
[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
