Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 3, an embodiment of the present invention provides an intercom, including a body 1, an antenna 3 and a slider 2, wherein the antenna 3 is connected to the slider 2, the body 1 is provided with a slot 11 for accommodating the antenna 3 and the slider 2, the slider 2 is movably engaged in the slot 11, and the slider 2 slides along the slot 11 to accommodate the antenna 3 in or slide out of the slot 11.

The front of the body 1 is provided with a display screen 17 and a plurality of control keys 19. Specifically, the display screen 17 is arranged above the control key 19 and is used for displaying the frequency band, time and electric quantity of the display screen; the number of the control keys 19 is 12, the control keys comprise 10 number keys (0 to 9), 1 on-off key and 1 setting key, and a communication channel and time can be preset through the setting keys, so that the interphone automatically modulates the frequency. The buckle is arranged at the back of the body 1 and used for fixing the interphone on clothes or a belt during carrying, so that the interphone is convenient to carry during use.

The placing groove 11 is arranged on the left side of the body 1, the upper end of the placing groove 11 is opened, and the lower end is closed. The bottom of the placing groove 11 close to the opening end and the closed end is provided with a plug jack 15. In one of the plug openings 15, a plug is provided, by means of which dust is prevented from entering the plug opening 15 and causing a contact failure. In this embodiment, the upper and lower plugs 15 are connected to the signal transceiver in the body. Thus, the antenna 3 can communicate both when extended and when retracted. Experiments prove that when the power is 2 watts and the antenna 3 is retracted, the communication distance in a city is 700 m; when the power is 5 watts and the antenna 3 is retracted, the communication distance in the urban area is 3400 m.

Two side walls of the placing groove 11 are provided with guide grooves 112 for clamping the sliding block 2 and guiding the sliding block 2; one end of the guide slot 112 is open, and the other end is closed, and the opening direction of the guide slot is consistent with the direction of the antenna 3 sliding out of the placing slot 11. The opening end of the guide groove 112 is provided with a movable stop block 13, one end of the stop block 13 is provided with a clamping structure fixed with the body 1, so that when the stop block 13 is pushed horizontally, the stop block 13 is fixed on the body 1, the sliding of the sliding block 2 from the placing groove 11 is prevented, and meanwhile, the antenna 3 is replaced after the stop block 13 is horizontally pulled out.

The slider 2 includes a slider body 21 and 2 projections 213, and the projections 213 are formed by projecting portions of two opposite sides of the slider body 21 to respective outer sides. The slider 2 is engaged with the guide groove 112 through the projection 213 and is engaged with the installation groove 11.

A connecting piece used for connecting the antenna 3 and the body 1 is arranged in the sliding block 2. When the sliding block 2 moves, the connecting piece is arranged to move in order to ensure that the connecting piece is not abraded. Specifically, the connecting element is arranged in the slider body 21, the connecting element is connected with the antenna 3 through a signal transmission line, one end connected with the body 1 is a plug 25, and the plug 25 is not flush with the surface of the inner side of the slider 2 (the plug 25 is recessed in the slider 2).

In other embodiments, the connection end of the connecting element and the antenna 3 is also configured as a plug 25, the connection end of the antenna 3 and the connecting element is configured as a jack 15, and the connection end of the antenna 3 and the sliding block 2 can move up and down a certain distance in the sliding block 2.

The slider 2 is provided with a push button 23 on the outside for pushing the connector to move, so that the plug 25 can be inserted into or removed from the jack 15, and the antenna 3 can be connected with or disconnected from the body 1.

When the plug-in type plug connector works, the plug at the upper end of the bottom of the placement groove 11 is pulled out, the plug jack 15 at the upper end is exposed, and then the key 23 is pressed, so that the plug 25 of the connector is separated from the plug jack 15 at the lower end of the bottom of the placement groove 11; pushing the slide block 2 to push the antenna 3 out of the placing groove 11; when the sliding block 2 abuts against the stop block 13, the key 23 is pressed again, so that the plug 25 of the connecting piece extends out of the sliding block 2 and is inserted into the plug hole 15 at the upper end of the bottom of the accommodating groove 11, and the antenna 3 is connected with the body 1; and finally, the plug blocks the lower plug hole 15. When resting, the operation is reversed.

In the product of the utility model, the slide block 2 slides along the placing groove 11 to lead the antenna 3 to be contained in or slide out of the placing groove 11, thereby effectively preventing the antenna 3 from being damaged in the storage or carrying state and being convenient for replacing the damaged antenna 3 or the antenna 2 with stronger receiving capacity; and the upper and lower both ends of the slot 11 are all provided with the plug jack 15 connected with the signal receiving and transmitting device of the body 1, thus realizing that the interphone can communicate in any state of the antenna 3.
