Summary of the invention
There are the problems referred to above in the utility model for existing technology, a kind of tube rotation mechanism of LED fluorescent tube has been proposed, the rotating mechanism of this LED fluorescent tube can make the LED fluorescent lamp accurately adjust to needed position, makes the LED fluorescent tube be positioned at best light angle.
The utility model is realized by following technical proposal: a kind of tube rotation mechanism of LED fluorescent tube, comprise the plug one with locating ring and the plug two with clamping joint, described clamping joint is connected to plug one and plug two formation axial restraints is circumferentially rotated, it is characterized in that, be provided with tumbler between described plug one and the plug two, described tumbler is enclosed within outside the above-mentioned locating ring, one end of tumbler and above-mentioned plug two are connected, and are provided with when plug one and plug two relative rotations control plug one and plug two between the other end of described tumbler and the plug one and decide the angular turn structure by what certain angle rotated.
Fluorescent tube is fixed on the plug one, and plug two is fixed on the support, and locating ring is used for circumferentially fixedly tumbler, when rotating fluorescent tube, plug one is realized circumferentially rotating with plug, and tumbler rotates in deciding the angular turn structure, is accurately positioned in suitable lighting angle thereby will regulate the rotation of LED fluorescent lamp.
In the tube rotation mechanism of above-mentioned LED fluorescent tube, described plug two comprises connector and cover cap, described clamping joint is arranged on the connector bottom, and described connector forms axial restraint with the clamping of locating ring phase and circumferentially rotates, and described cover cap is connected to connector top.Driving cover cap by connector rotates.
In the tube rotation mechanism of above-mentioned LED fluorescent tube, describedly decide the angular turn structure and comprise several projections and be arranged on internal gear on the plug one, described projection is connected on the tumbler by elastic construction, described plug one is provided with groove, above-mentioned internal gear is positioned on the inwall of groove, and above-mentioned tumbler is installed in the groove and projection is stuck between adjacent two teeth of internal gear.When tumbler rotated, projection was received the active force of internal gear teeth wall, at this moment, elastic construction elastic deformation projection inside contracts, when projection rotates between lower two teeth, owing to be not subject to the active force of teeth wall, elastic deformation recovers, and projection plays again the effect of location to tumbler.
In the tube rotation mechanism of above-mentioned LED fluorescent tube, the described teeth that are arranged on the internal gear on the plug one are evenly distributed on the inwall of groove.Teeth evenly distribute, and the angle between adjacent two teeth is certain, so that the angle of tumbler rotation is certain, make the tube rotation location more accurate by the angle rotating light tube.
In the tube rotation mechanism of above-mentioned LED fluorescent tube, the upper end of described tumbler is provided with several equally distributed grooves, and described connector is provided with several and matches with the tumbler upper groove for tumbler being carried out the spacing limited block of circumferential and axial when connector and plug one clamping.When connector during with the clamping of locating ring phase, the limited block on the connector, just the groove with tumbler top matches, and tumbler is fixed.
In the tube rotation mechanism of above-mentioned LED fluorescent tube, also offer the stroke groove on the described plug one, described connector lower end is provided with the slide block that matches with the stroke groove.Because the reasons in structure of LED fluorescent lamp, the rotational angle of the travel limits fluorescent tube by the stroke groove is regulated the LED fluorescent tube in the larger travel range of illuminance.
Compared with prior art, the tube rotation mechanism of this LED fluorescent tube is by the internal gear of even distribution teeth and the projection on the tumbler, so that each rotation all is with certain angular turn, avoid occurring rotating excessive situation, and and elastic construction cooperates, projection can produce the sound with the teeth collision when rotating, make the user when rotating, can tentatively determine according to the sound situation of rotating, the displacement that has realized tube rotation is accurate, makes the LED fluorescent tube light angle that offers the best.
