Abstract
The invention relates to an interphone having a modified adjusting knob, which comprises an interphone body and a plastic shell covered on the interphone body. The interphone body is at least connected with two adjusting knobs which are on the same central line; and at least one of the adjusting knobs is positioned inside the plastic shell. By effectively modifying the adjusting knobs, the shortcomings that the adjusting knob of the traditional interphone is easy to bend and the error operation is easy to occur are overcome.
Description
Technical field
The present invention relates to a kind of intercom, be meant the improved intercom of a kind of adjusting knob especially.
Background technology
Intercom is mainly used in industries such as public security, civil aviaton, transportation, water conservancy, railway, manufacturing, building, service, is used for contact and command scheduling between the member of community, links up efficient and improves the quick reaction capability of handling accident to improve.Along with intercom gets into the commercial market, people's out on tours, shopping also begin to use more and more intercom.Intercom does not receive network limits, and in the not yet covered with networks place of arriving, intercom can let the user easily link up; Intercom provides one to one, and the talking mode of one-to-many is said once pressing; Simple to operate; Order is linked up freer, especially under the situation of intervention schedule and collective's cooperative work, because intercom has above-mentioned advantage; Even if so in today that mobile phone is popularized, intercom still occupies a tiny space on market.
Traditional intercom mainly comprises intercom body, volume/switch adjusting knob and frequency adjustment knob etc.Said adjusting knob comprises that the plastics knob and the end that are positioned at the intercom body outside are fixedly connected the power transmission shaft that the other end is connected with the circuit of intercom body interior with the plastics knob.Present intercom volume/switch adjusting knob and frequency adjustment knob concern nothing more than two kinds of positions, specify with reference to the accompanying drawings.
With reference to Fig. 4; Intercom comprises that mainly intercom body 10, antenna 13, volume/switch adjusting knob 11 and frequency adjustment knob 12 connect together through the power transmission shaft 111,121 of two coaxial lines; The plastics knob 112 of volume/switch adjusting knob 11 is positioned at plastics knob 122 tops of frequency adjustment knob 12; Though this intercom is easy to use,, make that the power transmission shaft 111 that stretches out intercom body 10 is long because its two plastics knobs 112,122 all are positioned at the outside of intercom body 10; Usually can intercom be dropped because of carrier's unconscious running, cause power transmission shaft 111 flexural deformations.
With reference to Fig. 5, the plastics knob 141,151 of volume/switch adjusting knob 14 and frequency adjustment knob 15 lays respectively at the left and right sides at intercom body 10 tops.Because the intercom own vol is less, therefore two plastics knobs 141,151 just lean on closerly.Though a wherein plastics knob and then misoperation of rotation of another knob 151,141 in 141,151 o'clock usually can appear rotating in the generation of diastrophic situation in the time of can effectively avoiding dropping.
Summary of the invention
The invention provides the improved intercom of a kind of adjusting knob, its purpose is to overcome the adjusting knob easy deformation of traditional intercom and the defective that is easy to generate misoperation.
The improved intercom of a kind of adjusting knob comprises the intercom body, is coated on the plastic casing of intercom body, and said intercom body is connected with the adjusting knob of two concentricity lines at least, and said adjusting knob has an inboard that is positioned at plastic casing at least.
The side of said plastic casing upper end is provided with lateral opening, and the said adjusting knob that is positioned within the plastic casing partly protrudes said lateral opening.
Said adjusting knob comprises volume/switch adjusting knob and the frequency adjustment knob that is connected with the intercom body, and said volume/switch adjusting knob comprises that part is positioned at the volume power transmission shaft and the fixedly sleeved volume plastics knob on the volume power transmission shaft of intercom body interior; Said frequency adjustment knob comprises that part is positioned at the frequency power transmission shaft and the fixedly sleeved frequency plastics knob on the frequency power transmission shaft of intercom body interior, said frequency power transmission shaft hollow, and be sheathed on the volume power transmission shaft; Said volume plastics knob and frequency plastics knob lay respectively at the outside at said plastic casing top with inboard; Said frequency plastics knob portion protrudes from said lateral opening.
Said frequency power transmission shaft and volume power transmission shaft are cylindrical, and lateral surface is equipped with groove; The madial wall of said frequency plastics knob and volume plastics knob is respectively equipped with the projection with above-mentioned groove fit.
Said frequency plastics knob is gear-like; And its upper surface is provided with frequency scale equally spacedly; The top of said plastic casing be provided with one can observe the component frequency scale opening, and the plastic casing of said opening lateral margin be provided with one be used for the reading frequency scale pointer.
Said frequency scale and pointer are carved respectively in said frequency plastics knob upper surface and plastic casing top.
Can know by the above-mentioned description of this invention; Compared with prior art; The invention has the advantages that: because volume/switch adjusting knob and the coaxial socket of frequency adjustment knob; And volume plastics knob and frequency plastics knob separate with plastic casing, therefore can overcome the adjusting knob easy deformation of traditional intercom and the defective that is easy to generate misoperation effectively.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 6; The improved intercom of a kind of adjusting knob; Comprise intercom body 1, antenna 6, be coated on the plastic casing 2 of intercom body 1, volume/switch adjusting knob 3 and the frequency adjustment knob 4 that is connected with intercom body 1, said volume/switch adjusting knob 3 comprises that part is positioned at the inner volume power transmission shaft 31 of intercom body 1 and fixedly sleeved in the volume plastics knob 32 of volume power transmission shaft 31 upper ends; Said frequency adjustment knob 4 comprises that part is positioned at the inner frequency power transmission shaft 41 of intercom body 1 and fixedly sleeved in the frequency plastics knob 42 of frequency power transmission shaft 41 upper ends; Said frequency power transmission shaft 41 hollows; And be sheathed on volume power transmission shaft 31; Said volume plastics knob 32 and frequency plastics knob 42 lay respectively at the outside at said plastic casing 2 tops with inboard, thereby effectively avoid the generation of misoperation; The side of said plastic casing 2 upper ends is provided with a lateral opening 5, and said frequency plastics knob 42 parts protrude from said lateral opening 5, frequency plastics knob 42 adjustings of frequency through protruding from lateral opening 5.
With reference to Fig. 2, said frequency power transmission shaft 41 is cylindrical with volume power transmission shaft 31, and lateral surface is respectively equipped with groove 411,311; Said frequency plastics knob 42 is respectively equipped with the projection (not drawing among the figure) that cooperates with above-mentioned groove 411,311 with the madial wall of volume plastics knob 32; Frequency plastics knob 42, volume plastics knob 32 are connected together with frequency power transmission shaft 41, volume power transmission shaft 31 securely, thereby effectively regulate the size of volume or frequency and the open/close state of control intercom.
