Abstract
The utility model provides an interphone positioning channel button apparatus, from up to down successively comprising a button cap, a tooth profile knob and a tooth profile groove. The tooth profile knob is provided with a round ball button, the lower end of which is uniformly provided with rotary teeth; the tooth profile groove is fixedly provided with a rotary shaft which is provided with a rotary channel section and a positioning channel section for movable positioning with the round ball; angle positioning teeth fitting with the rotary teeth are uniformly distributed in the tooth profile groove. According tot the utility model, the purposes of fixing a channel and accurately positioning each channel are realized by up and down movable positioning of the tooth profile knob and the fit positioning between the angle positioning teeth and the rotary teeth; the case of mis-turning to other channels in operation processes can be avoided so as to avoid inconvenience for users. The interphone positioning channel button apparatus has the characteristics of safe operation and a long service life and is suitable for the use of most interphone channel button apparatuses.
Description
Technical field
The utility model relates to a kind of PBU pushbutton unit, particularly a kind of locating channel PBU pushbutton unit of intercom.
Background technology
The intercom of commonly seeing comes receiving and transmitting signal through the knob CU channel unit.Knob on the intercom of being sold in the market is general to adopt the structure of directly coincideing, and does not have fixture, in frequent use, very easily comes off, and causes its useful life not long.After user's selective channel, also cause misoperation easily, often misroute other channels and make the intercom can not normal talking, bring very big inconvenience to both call sides.
Summary of the invention
In order to address the above problem; The utility model provides a kind of locating channel PBU pushbutton unit of intercom, comprises button cap, flute profile knob and flute profile groove from top to bottom successively, and said profile of tooth knob is provided with round ball button; Its lower end average mark is furnished with rotary teeth; Be fixed with rotation axis on the said flute profile groove, rotation axis is provided with rotation draw-in groove and the locating groove with circle ball button activity location, and average mark is furnished with the angle location tooth that coincide each other with rotary teeth in the described serrate slot.
Said button cap is provided with the profile of tooth knob is fixed on the screw on the rotation axis.
Said round ball button is located up and down and is rotated draw-in groove and locating groove.
The quantity of described angle location tooth is decided by the angular distribution of rotation axis.
The beneficial effect of the utility model is: because profile of tooth knob and corresponding respectively round ball button and the draw-in groove of being provided with of rotation axis; The profile of tooth knob carries out up and down location through circle ball button to rotation axis; The profile of tooth knob can be fixed and frequency modulation channel respectively when being pressed or pulling up, and then the user is unlikely to because knob can not carry out accurately fixing and misrouting to other channels to each channel.In profile of tooth knob and the serrate slot respectively average mark be furnished with the rotary teeth and the angle location tooth of mutual correspondence, the profile of tooth knob can accurately be located around the rotation axis flexible positioning formula on serrate slot rotation and to each channel.
Description of drawings
Fig. 1 is the overall structure figure of the utility model.
(mark among the figure: 1, button cap, 11, screw, 2, the profile of tooth knob, 21, the circle ball, 22, rotary teeth, 3, rotation axis, 31, rotate draw-in groove, 32 locating grooves, 4, serrate slot, 41, the angle location tooth)
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model is a kind of locating channel PBU pushbutton unit of intercom, by button cap 1, and profile of tooth knob 2, rotation axis 3 and serrate slot 4 are formed.Wherein, Button cap 1 is installed on the periphery of profile of tooth knob 2, plays the effect of the whole device of protection, is provided with screw 11 in the central authorities of button cap 1; Effect is that profile of tooth knob 2 is fixed on the rotation axis 3 to prevent that profile of tooth knob 2 from coming off from rotation axis 3, and rotation axis 3 is fixed in the central authorities of serrate slot 4.The profile of tooth knob is provided with round ball button 21 for 2 li; Corresponding being provided with rotated draw-in groove 31 and locating groove 32 on rotation axis 3; Circle ball button 21 can carry out up and down location respectively with two draw-in grooves; Making can be well with the channel fixed bit when profile of tooth knob 2 pulls up rotation frequency modulation and presses, the rotary teeth 22 of the lower end mean allocation of profile of tooth knob 2 and rotation axis 3 equal angular.Groove edge average mark in serrate slot 3 is furnished with the angle location tooth 41 with rotary teeth 22 each other identical angles; Rotary teeth 22 is coincide with angle location tooth 41 neatly locatees; The quantity of angle location tooth 41 is decided by the angular distribution of rotation axis 3, has also determined the Reasonable Orientation of profile of tooth knob to each channel simultaneously.As long as the user presses its knob after pulling up profile of tooth knob rotation in use and forwarding required channel to again, just can be fixed on the selected channel and can not misinformate, thereby guarantee instant normal talking to other channels.The utility model easy-to-operate, long service life, the installation that is fit to most of intercom locating channel button with manipulate.
Above-described, be merely a preferred embodiment of the utility model, can not limit the scope that this practicality is implemented, every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
