Technical Field

[0001] The utility model relates to the technical field of interphones, in particular to an interphone with anti-fall, waterproof and hidden display functions. Background Art

[0002] Walkie-talkie is a two-way mobile instant communication tool that can conduct calls at an effective distance without any network support and without incurring any call charges. It is suitable for relatively fixed and frequent call occasions. The existing intercom includes a shell body, a battery, a back cover and a button. A display screen is provided on the front side of the shell body, an aluminum plate is provided inside the shell body, a battery slot is provided on the aluminum plate, the rear side of the battery is opened and the battery is embedded therein, a buckle is provided on the inner end face of the back cover, and the shell body has a slot matching the buckle. The back cover can be detachably mounted on the rear side of the shell body through the cooperation of the buckle and the slot and seals the battery. The rear side of the shell body is provided with a back clip located in the upper range of the back cover, the back clip has a mounting portion and a clamping plate, the mounting portion is screwed on the rear side of the back cover, the clamping plate is hinged on the mounting portion and arranged opposite to the mounting portion, the button is located on the four sides of the shell body, and the button has a switch key and a PPT transmission button; when used, the buckle and the slot are clamped to realize the connection between the shell body and the back cover, and then the clamping plate is moved away from the mounting portion, so that a certain angle is formed between the clamping plate and the mounting portion, so that the entire intercom is fixed on a fixed object.

[0003] When the user is not using the walkie-talkie for work, the user will fix the walkie-talkie on a fixed object for easy carrying, such as putting it on the hand or fixing it on clothing. However, when the user is in a complex environment, the walkie-talkie is easy to slip from the user's hand or clothing due to sweating or collision, causing the walkie-talkie to fall, collide, or get wet. The rear cover and the shell body are easily separated and damaged due to the impact force generated by the fall, causing the battery to fall out, that is, the battery will collide; in addition, the outer side of the shell body also lacks a good anti-fall structure, and the shell body is also easily damaged by the impact force when it falls to the ground, which in turn affects the normal use of the walkie-talkie.

[0004] In view of this, the inventor of this case conducted an in-depth study on the problem, which resulted in this case. Utility Model Content
