Description

Technical Field

[0001] The utility model relates to the technical field of intercoms, in particular to a flip cover protection structure of an intercom. Background Art

[0002] Walkie-talkies are two-way mobile communication tools that allow you to make calls without any network support and without incurring phone charges. They are suitable for relatively fixed and frequent calls. There are currently three types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies. Currently, most walkie-talkies do not have protective covers, leaving buttons and speakers exposed to the outside, which results in the walkie-talkies not being very waterproof or dustproof.

[0003] For example, patent application number CN201921716437.X discloses a walkie-talkie with a protective cover, including a walkie-talkie and a protective cover, a hinge storage groove is provided at the bottom end of the back of the walkie-talkie, a card slot and a buckle storage groove are provided at the upper end of the back of the walkie-talkie, a card block is slidably connected inside the slide groove, a lead screw is rotatably connected above the card block, the top of the lead screw passes through the walkie-talkie and is fixedly connected with a knob, a first hinge is fixedly connected to the bottom of the back of the walkie-talkie, a buckle is welded to the top of the protective cover, a connecting block is welded to the upper end of the front of the protective cover, a groove is provided on the upper surface of the connecting block, and a hanging buckle is welded to the back of the left and right ends of the protective cover, a bottom cover is provided at the bottom of the protective cover, and the right end of the bottom cover is fixedly connected to the first hinge. By buckling the protective cover with the front of the walkie-talkie, the buttons and speakers of the walkie-talkie can be protected, and it plays a waterproof and dustproof role. By hanging the protective cover, the walkie-talkie can be hung at a desired place, which is convenient for carrying the walkie-talkie.

[0004] The device is connected by a rotating protective cover on the top of the intercom, but the protective cover is connected to the intercom and is not easy to remove. For people who do not like to use flip covers, this intercom is not considered. At the same time, the protective cover is buckled and has poor stability. When people move, it is easy to accidentally touch it and cause the protective cover to flip over. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4 In the utility model, a flip cover protection structure of an intercom includes an intercom body 1, a display screen 2, a button 3 and a speaker 4, the display screen 2, the button 3 and the speaker 4 are all installed on the top of the intercom body 1, the intercom body 1 is detachably connected with a mounting frame 5, the inner wall of the mounting frame 5 is rotatably connected with a synchronous shaft 6, the top of the synchronous shaft 6 is fixedly connected with two flip columns 7, the top of the intercom body 1 is slidably connected with a protective cover 8, the display screen 2, the button 3 and the speaker 4 are all located at the bottom of the protective cover 8, the left side of the protective cover 8 is fixedly connected with two guide plates 9, the guide plate 9 is slidably connected to the top of the flip column 7, the bottom of the protective cover 8 is fixedly connected with a linkage block 10, the top of the mounting frame 5 is provided with two movable grooves 11, the bottom end of the linkage block 10 is located inside the movable groove 11, and the two sides of the linkage block 10 are fixedly connected with expansion blocks 12, and the inner wall of the movable groove 11 is fixedly connected with two extension plates 13, the extension plate 13 is located at the top of the extension block 12 and is slidably connected with the extension block 12.

[0022] Positioning pins 14 are threadedly connected to the left and right sides of the mounting frame 5 , and positioning holes 15 are opened on the left and right sides of the intercom body 1 . The positioning pins 14 penetrate the mounting frame 5 and extend to the inside of the positioning holes 15 .

[0023] Two magnetic blocks 18 are fixedly connected to the top of the mounting frame 5 , and a metal sheet 19 is connected to the linkage block 10 . The metal sheet 19 is located on the left side of the magnetic block 18 and is magnetically connected to the magnetic block 18 .

[0024] The user clamps the mounting frame 5 on the intercom body 1 so that the position of the positioning pin 14 is aligned with the positioning hole 15. Then the user passes the positioning pin 14 through the mounting frame 5 and connects it inside the positioning hole 15, thereby quickly completing the connection of the protective cover 8. Then the user flips the protective cover 8 so that the protective cover 8 is at the top of the intercom body 1, and the linkage block 10 and the expansion block 12 are inside the movable groove 11. Then the user slides the protective cover 8 to the right so that the expansion block 12 is located at the bottom of the extension plate 13, and the guide plate 9 slides on the flip column 7 until the metal The sheet 19 fits with the magnetic block 18, and the linkage block 10 is restricted to remain stable, so that the protective cover 8 remains stable. When the intercom body 1 is not in use, the protective cover 8 can play a role in dust and drop prevention. When the button 3 needs to be operated, the user can slide the protective cover 8 to the left to expose the display screen 2, and the linkage block 10 slides synchronously until the expansion block 12 moves out from the bottom of the extension plate 13. At this time, the expansion block 12 is not restricted and is at a certain distance from the extension plate 13. The user flips the protective cover 8 to make the synchronization shaft 6 start to rotate, thereby completing the opening of the protective cover 8.

[0025] In the utility model, a protective cover 8 is provided on the top of the intercom body 1 to prevent the intercom switch from being turned on or off due to accidental operation or touch, thereby reducing operational errors. At the same time, dust, pollutants or moisture can be prevented from entering the inside of the intercom, thereby improving its dust and water resistance, which is particularly important in outdoor, harsh environments or special workplaces, and can extend the service life of the intercom. At the same time, the protective cover 8 needs to slide before it can be flipped under the restriction of the extension plate 13, thereby reducing the risk of accidental flipping, and preventing the protective cover 8 from being accidentally opened or closed due to misoperation or touch, thereby ensuring that the intercom is always in the state expected by the user and improving the stability of the protective cover 8.

[0026] See also Figures 1 to 3 , wherein: a guide groove 16 is opened on the guide plate 9 , and the top end of the flip column 7 is located inside the guide groove 16 and is slidably connected to the inner wall of the guide groove 16 .

[0027] In the present invention, the setting of the guide groove 16 can improve the stability between the guide plate 9 and the flip column 7, so that the guide plate 9 and the flip column 7 slide more smoothly, thereby completing the flipping of the protective cover 8.

[0028] See also Figure 1 and 3 , wherein: a transparent plate 17 is fixedly connected to the top of the protective cover 8 , and the transparent plate 17 is located on the top of the display screen 2 .

[0029] In the present invention, when the protective cover 8 is in the protective state, the user can also observe the specific situation of the display screen 2 through the transparent plate 17 to prevent errors in the band channel and reduce the steps required for the user to operate.

[0030] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and its improved conception of the utility model, which should be included in the protection scope of the utility model.
