Detailed Description
The telescopic antenna structure provided by the embodiment is used for an interphone terminal, the interphone terminal comprises a main shell 1, an antenna 2 is installed on the main shell 1, an electric signal butt joint 21 is arranged at the bottom of the antenna 2, an electric signal butt joint hole 11 matched with the electric signal butt joint 21 is formed in the main shell 1, and the electric signal butt joint 21 is detachably connected with the electric signal butt joint hole 11; the main shell 1 is further provided with a containing hole 12 for containing the antenna 2 along the length direction of the main shell, a plurality of guide sliding grooves 13 are uniformly distributed on the inner side surface of the containing hole 12 along the circumferential direction of the containing hole, and guide sliding tables 22 which are respectively matched with the guide sliding grooves 13 one by one are arranged on the outer side surface of the antenna 2; an elastic part 14 is additionally arranged at the bottom of the accommodating hole 12, and two ends of the elastic part 14 are respectively abutted against the bottom of the accommodating hole 12 and the bottom of the antenna 2; a sealing sliding groove 15 is additionally arranged at the opening of the containing hole 12, a sealing cover plate 3 is arranged in the sealing sliding groove 15 in a sliding mode, two sealing bosses 31 are symmetrically arranged on the side face of the sealing cover plate 3, and a sealing clamping groove 16 matched with the sealing bosses 31 is arranged on the inner side face of the sealing sliding groove 15; an annular sealing groove 17 is formed in the bottom surface of the sealing sliding groove 15 along the outer side of the opening of the accommodating hole 12, and an elastic sealing member (not shown in the figure) is filled in the annular sealing groove 17.
It should be noted that, referring to fig. 1, when in use, the electrical signal docking connector 21 at the bottom of the antenna 2 is connected to the electrical signal docking hole 11 on the main housing 1, and then the normal use is ready. In this embodiment, the electrical signal docking head 21 is in threaded connection with the electrical signal docking hole 11, so that the antenna 2 can be conveniently mounted and dismounted.
When the interphone terminal is not needed, the antenna 2 can be placed in the containing hole 12 of the main shell 1, the antenna 2 is convenient to store, and the antenna 2 is prevented from being lost. Simultaneously, can avoid among the prior art, fixed connection structure leads to the risk of antenna 2 rupture between antenna 2 and the intercom terminal. The convenience is brought to carrying of the interphone terminal. Specifically, the guide sliding tables 22 on the outer side surfaces of the antennas 2 are respectively inserted into the guide sliding grooves 13 on the inner side surfaces of the accommodating holes 12 in a one-to-one correspondence manner, so that the antennas 2 can be inserted into the accommodating holes 12. By adding the structure of the guide chute 13 and the guide sliding table 22, the antenna 2 can be fixed in the accommodating hole 12, and the antenna is prevented from shaking in the accommodating hole 12 and being damaged. After the antenna 2 is placed in the accommodating hole 12, the sealing cover plate 3 slides in along the sealing sliding groove 15, and the stability of installation of the sealing cover plate 3 is ensured through clamping between the sealing boss 31 and the sealing clamping groove 16. Meanwhile, the annular sealing groove 17 is additionally arranged at the bottom of the sealing sliding groove 15, and an elastic sealing element is filled, so that the sealing performance between the sealing cover plate 3 and the sealing sliding groove 15 can be ensured, and substances such as water and the like are prevented from entering the accommodating hole 12 through a gap between the sealing cover plate 3 and the sealing sliding groove 15.
It should be noted that the bottom of the accommodating hole 12 is provided with an elastic member 14, and the elastic member 14 is provided as a spring. After the sealing cover plate 3 is installed, the sealing cover plate 3 is abutted to the top of the antenna 2, so that the antenna 2 is pressed to the bottom of the accommodating hole 12, and the spring at the bottom of the accommodating hole 12 deforms under the extrusion action of the antenna 2. When the antenna 2 needs to be taken out, the sealing cover plate 3 slides out of the sealing sliding groove 15, the antenna 2 loses the pressure of the sealing cover plate 3 and extends out of the accommodating hole 12 under the action of the elastic restoring force of the spring, and therefore a user can take the antenna 2 out of the accommodating hole 12 conveniently.
Further, the cross sections of the guide sliding chute 13 and the guide sliding table 22 are semicircular, so that the friction force between the guide sliding chute 13 and the guide sliding table 22 is reduced, and the antenna 2 is convenient to mount and take out. The number of the guide sliding chute 13 and the number of the guide sliding table 22 are respectively set to six, so that the stress between the guide sliding chute 13 and the guide sliding table 22 is ensured to be uniform, the stability of the antenna 2 in the accommodating hole 12 is improved, and the movement of the antenna is limited.
Further, elastic sealing element sets up to the sealing rubber strip, and the sealing rubber strip is with low costs, and is sealed effectual, simple to operate makes things convenient for the change in later stage.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
