Description

Structure is waved in the Christmas tree twisting

The utility model relates to a kind of Christmas tree, particularly a kind of artificial Christmas.

During Christmas Day, in various occasions, can see Christmas tree miscellaneous everywhere, having plenty of and adopt true tree decoration to form, more is the artificial Christmas that utilizes plastic rubber ejaculate molding to make, on these trees, also hang and bind various small bell, bright ball, present and miniature bulb and decorated, these structures though also can reach the effect that some are viewed and admired and modify, lack the excellent effect of the Nature trees dynamic concept.

The purpose of this utility model is to provide a kind of improved Christmas tree twisting to wave structure, it have similar with trees in the Nature dynamically, cooperate corresponding ornament, the effect of make its richer decoration, viewing and admiring and playing.

Utility model is achieved in that Christmas tree twisting waves structure one transmission mechanism and be installed in the trunk, and the twisting of transmission mechanism waved output and stretched in the trunk; Output outer surface and trunk touch, and drive rod in wave shape stretches through in the endoporus of the elastic tube of output; One electric appliance component is installed in the trunk, and its motor is to drive with transmission mechanism and is connected; The output that motor drives transmission mechanism through transmission mechanism orders about the trunk twisting that touches with output and waves.

Transmission mechanism can be the band transmission and gear drive constitutes jointly multi-stage speed-reducing transmission device or gear drive multi-stage speed-reducing transmission device; Output elastic tube one end is installed in the recessed edge of end cap place; Drive rod one end of output is installed in the main shaft of output precision; Pore radius is less than the maximum height of drive rod waveform crest apart from center line in the elastic tube, and diameter of bore is then greater than the drive rod diameter of axle.

The utility model mat motor-driven, output is rocked with the waveform of its drive rod in rotation, one end is fixed, other end output freely is the twisting swinging condition, therefore and the trunk that touches of output wave along with producing to twist, at this moment, Christmas tree is the Nature state as swaying in gentle breeze especially, improved the appreciative value of Christmas tree, and at the same time, the small bell of decorating on Christmas tree can shake and sends the melodious sound along with trunk, bright ball, miniature bulb is under the setting off of the light shadow of the trees, sparkling and crystal-clear flicker is too beautiful to be absorbed all at once, makes Christmas tree bring bigger enjoyment to the people, thereby has more and view and admire, the value of decorating.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

With reference to Fig. 1, Christmas tree twisting is waved structure and is included trunk 1, trunk 2, transmission mechanism 3 and electric appliance component 4, and its trunk 1 and trunk 2 are made and are connected with by plastic cement and be one, and trunk 2 can ccontaining transmission mechanism 3 for hollow and the structure of electric appliance component 4.

Transmission mechanism 3 (shown in Fig. 2,3,4) includes housing 31, band transmission 32, jackshaft 33, axle 34, idler gear 35, output precision 36, end cap 37, output 38, wherein:

Housing 31 outsides set firmly motor 41, and motor 41 shaft extensions are passed housing 31 wall portions and stretched into housing 31 inboards;

Band transmission 32 comprises small pulley 321 on the shaft extension that is installed in motor 41, with 322, big belt wheel 323 and and big belt wheel 323 be the pinion 324 of one, wherein can be multiple selective structures such as plane section, V-type cross section, circular section or profile of tooth with 322, big belt wheel 324 slides on the fixed axis that is supported on housing 1;

Jackshaft 33, one ends are fixed on housing 1, and the other end is fixed on end cap 37, jackshaft 33 upper sliding sleeve idler gears 35, and idler gear 35 is one by gear wheel 351 and pinion 352 and forms, pinion 324 engagements on 351 of gear wheels and the big belt wheel 323;

Axle 34, one ends are fixed on housing 1, the other end and output precision 36 windings;

Output precision 36 is formed one by master gear 361 and main shaft 362, pinion 352 engagements of master gear 361 and idler gear 35, and master gear 361 slides over axle 34;

End cap 37, its cover plate 371 can be fixedly arranged on housing 1, and connected mode can be with bolt or bonding etc., and a flange 372 is established at the center of cover plate 371, and the endoporus of flange 372 just can be with the main shaft of output precision 36 and is slidingly matched, and constitutes an end bearing of output precision 36;

Output 38, include an elastic tube 381 and drive rod 382, elastic tube 381 can be whippy plastic cement pipe, rubber tube or similar pipe, one end of elastic tube 381 is installed in recessed edge 372 centers of end cap 37, be same axis status with the main shaft 362 of output precision 36, its other end then is the free end of free state; Drive rod 382 can be made by steel wire or similar material, and an end of drive rod 382 is installed in main shaft 362 centers of output precision 36, and its other end is the free end of free state then, and the axis of drive rod 382 is in wave shape, and this waveform can be at least one wave band; The radius of elastic tube 381 endoporus 3811 of output 38 is less than the maximum height of drive rod 382 waveform crests apart from center line, and by this, when drive rod 382 rotations, the largest motion track of its waveform will force the fixing elastic tube of an end 381 to produce twisting and wave; The diameter of endoporus 3811 is convenient to the two assembling greater than the diameter of axle of drive rod 382;
