Description

A kind of The Cloud Terrace that promotes pitching band sucker with cam mechanism

Technical field:

The utility model relates to the comprehensive The Cloud Terrace in a kind of indoor and outdoor

Background technique:

The Cloud Terrace is a kind of electronic bearing device of using with pitching that rotates for visualizer.Very many of at present commercially available The Cloud Terrace, but on this link of control pitching, all be to adopt forms such as worm and gear or gear driven basically.

Said structure has several significant disadvantage, at first be that structure is complicated, highly high, because their structure will occupy the The Cloud Terrace certain height, seem higher behind the loading visualizer, secondly be that sealing is poor, water-proof performance is bad, this is because electrical appliance part need be placed in the compartment, and two arms of The Cloud Terrace pitching plate need to reach outside the top of compartment, are stretching out the just difficult sealing in place like this, and the arm that stretches out need extend, and has reduced the pitching useful load of The Cloud Terrace so again greatly.Example is an example for present widely used 301 The Cloud Terraces, 6.8 kilograms of its deadweights, high 28 centimeters, 12 kilograms of load-carryings, elevation axis outlet port water proofing property very poor (a packing less hole is arranged), the smallest and the most exquisite and for example present 303C The Cloud Terrace, its profile is similar to 301 The Cloud Terraces, and conduct oneself with dignity 1.1 kilograms (plastics system) is high 18 centimeters, faces upward only 10 °, 1.5 kilograms of load-carryings, and water proofing property is relatively poor equally.These The Cloud Terrace bottoms do not have powerful adsorbent equipment in addition, can not be adsorbed on the car item.

Summary of the invention:

The purpose of this utility model is the present situation that is at above-mentioned indoor and outdoor The Cloud Terrace, provide that a kind of structure is extremely simple, water proofing property fabulous (it is also irrelevant to rain cats and dogs), big from useful load at the bottom of heavy and light, the height, during pitching, and the The Cloud Terrace of adsorbent equipment (being fit to automobile uploads) is arranged at the bottom.

For achieving the above object, the utility model is mainly realized by following structure, promptly in the electrical equipment box of The Cloud Terrace, the direct-flow deceleration electric motor of two vertical shafts is set, one axially down, by big or small azimuth gear, whole The Cloud Terrace upper half part is horizontally rotated, the another motor, axle stretches out electrical equipment box top vertically upward, directly drive (shrinkage pool is arranged) that the bottom is a level, the upper-end surface becomes the columnar cam of inclination shape, do 360 ° rotation, each contacts with the push rod of a band roller in the upper edge of this cam and front and back, and push rod is fixed on and faces upward on the plate inner plane, electricity just can force the pitching plate to do continual pitching movement up and down in the continuous rotation of cam like this.

Because cam mechanism has multiple structural type, can order about the pitching plate in principle and do pitching movement up and down, example is for making the oblique circular cylinder cam on " people " font cam of one side band tooth plate, by small gear, the tooth plate on the shaft that makes progress, directly promoting the man type cam moves forward and backward, by push rod same as described above, can make the pitching plate do pitching up and down (but this scheme needs front and back should establish reversing switch, turns to change motor) again.The utility model compared with prior art has following outstanding feature and good effect.

1, make The Cloud Terrace when outdoor application, water proofing property is better: this is that packing less passage has only a motor box axis hole because motor box makes progress, and the pedestal of this sky is higher than the box face, has cam to be covered with, and the ball place also scribbles butter and never easily intakes.

2, simple in structure, highly low, diameter is little, from heavy and light: reason is to have cancelled spiral shell wheel, screw rod, cam be arranged on again the pitching plate below, do not account for clear space, motor is to adopt the motor and the limit stoper thereof of flat vertical shaft to do a little improvement, so the deadweight about 2.5 kilograms, height only the 10-12 centimetre less than 301 The Cloud Terraces half.

3, pitching useful load is big: reason is that pitching plate and pushing mechanism thereof all are arranged on the box face, so the arm of pitching plate is very short, also can be zero, roller on the push rod is along rising on the inclined-plane, so pitching load just can increase, under same motor drove, its thrust was bigger than 301 The Cloud Terraces.

4, powerful adsorbent equipment is arranged: reason is the magnet that is provided with some brute forces on the bottom surface of base, and it can be very stable is adsorbed on The Cloud Terrace on the iron and steel object such as automobile top.The part that turns edge in the bottom surface in addition also is provided with several screws, so that can fix The Cloud Terrace with screw in case of necessity.

The utility model is applicable to car and the indoor and outdoor place use that all are short, narrow and small.

The utility model will be further described below in conjunction with accompanying drawing and mode of execution:

Description of drawings:

Accompanying drawing 1, be overall structure cut-away view of the present utility model

Accompanying drawing 2, be the cut-away view at another kind of embodiment's pitching small gear place, top

Embodiment:

As shown in Figure 1, the utility model has an axle 2 in the center of base 1, this axle covers 13 down with motor box and fixes, in box, there is one to be fixed on the azimuth motor 5 that covers down on 13, its axle is connecting orientation small gear 4, orientation small gear 4 is engaged on the orientation gearwheel 3, because gearwheel 3 is fixed on the base 1 motionless, when so motor 5 rotates, principle by relative movement, force small gear 4 to make horizontal circular movement around gearwheel 3, thereby upper half part of whole The Cloud Terrace moving axis 2 that rotates is horizontally rotated with following cover 13.Under motor box, also fixing the pitching decelerator 11 of a vertical shaft in addition on the cover 13, pass on it is axial and cover 12 on the motor, and with a upper-end surface be inclination shape, bottom end is that the cylindrical body cam 7 on plane is connected, the bottom surface of cam 7 is recessed partly to be enclosed within on the pedestal of ball 10, and each one of the upper end-face edge of cam 7 and front and back are fixed on the push rod 8 of the band roller on the lower plane of pitching plate 9 and contact, when cam 7 rotates a circle like this, just can force pitching plate 9 to do pitching up and down once, and continuity is arranged by push rod 8.

On the bottom surface of base 1, be fixed with the extremely strong magnet of several magnetic force 16, pasting one deck thin rubber film 17 under it, The Cloud Terrace is adsorbed on the iron and steel objects such as automobile top, for changing means of fixation, part is routed up on bottom sides edge at The Cloud Terrace base 1, is provided with some circular holes 25, so that be screwed The Cloud Terrace.

As shown in Figure 2, be the another embodiment example: the axle of pitch motor 11 drives pitching small gear 20 and rotates, it drives " people " font cam 7 that a side is carved with gear and moves forward and backward along the pedestal 10 of band balls, the upper edge of man type cam 7 push rods 8 of two band rollers same and on pitching plate 9 lower planes contact, thus can force pitching plate 9 do about pitching move.But this scheme needs to establish reversing switch 22 at pitching plate front and back appropriate location, so that motor 11 counter-rotatings, cam 7 is done oppositely to move.

The utility model is applicable on the car and use in all short, narrow and small indoor and outdoor places.
