Description
Technical field
The utility model relates to a kind of balance regulator, particularly a kind of magnetomechanical damping The Cloud Terrace balance regulator that is used for photographic camera or camera tripod.
Background technique
When taking, usually to use tripod as support with photographic camera or vidicon camera.Because photographic camera or vidicon camera have the needs that take a crane shot or face upward bat,, play the effect of balance adjustment so on tripod, the The Cloud Terrace that is used for fixing photographic camera or vidicon camera can be set.This balance adjustment is meant: in the certain of pitch angle scope, the operator can the manual adjustment photographic camera or the shooting direction of vidicon camera, unclamp hand after The Cloud Terrace can make photographic camera or vidicon camera keep current angle reposefully, can not shake or rotate.
On the existing The Cloud Terrace,, can use the mechanical damping disk technology in order to realize level and smooth shooting.This technology is used round surely copper sheet of multilayer and the moving circle of the multilayer copper sheet that axially is provided with along the mandrel of The Cloud Terrace, evenly smears damping grease between fixed, the moving circle copper sheet, and moving circle copper sheet group is fixedly connected with mandrel, and round surely copper sheet group is fixed through the ratchet cover plate and linked to each other with gearshift.When mandrel rotated, round surely copper sheet can rotate with moving circle copper sheet each other.Because the effect of damping grease can form the independent damping tray with a certain size damping force between fixed, the moving circle copper sheet, utilize the quantity of increase and decrease damping tray to realize the damping force size adjustment.The external end head of mandrel can fix with photographic camera or vidicon camera, and along with the adjustment of angle of shooting, mandrel also can rotate thereupon, and at this time the damping force of damping tray will the generation effect, and the prevention mandrel rocks.Utilize gearshift to regulate the quantity of damping tray, just can adjust the size of this damping force.After the size adjustment of this damping force is suitable, just can prevent rotating freely of mandrel, rock thereby make to take to be difficult for producing.
Because this mechanical damping dish must rely on frictional force to work, so in use there is following problem:
1, frictional force can produce wearing and tearing at work inevitably; Because the surface accuracy of copper sheet damping tray is very high; So will produce very big influence to uniformity to each of damping force in case wearing and tearing occur; Incipient wearing and tearing can cause the shooting shake under some angle, then can cause the obvious decline of The Cloud Terrace equilibrant after wearing and tearing are comparatively serious, therefore; Use the The Cloud Terrace balance regulator life-span of mechanical damping disk technology unsatisfactory, especially be not suitable for the situation of high power bust shot and frequent adjustment angle of shooting;
2, the mechanical characteristic of damping grease self is easy to change along with temperature variation, and the damping force when temperature is low is big, and the damping force when temperature is high is little, and therefore in the apparent in view place of temperature variation, this mechanical damping disk technology also has tangible narrow limitation;
3, in order to realize being adjacent to and unclamping of a plurality of damping trays, also special gearshift need be set on The Cloud Terrace, so just make the cost height and the complex structure of The Cloud Terrace.
The model utility content

Shown in Fig. 2 and 3; Ring magnet 104 is provided with four stop ears; Push rod 107 is as the damping adjustable lever; The one of which end withstands on the stop ear of ring magnet 104, and the other end then stretches out outside the carriage 106, promotes push rod 107 through the handwheel 110 that is arranged on carriage 106 outsides and axially moves towards annular iron plate 103.Corresponding these four stop ears have been offered four sections chutes on the inwall of shell 101, between chute bottom land and stop ear, press to be provided with spring 109.Spring 109 withstands ring magnet 104, makes ring magnet 104 remain with push rod 107 and contacts, and when handwheel 110 revolutions, spring 109 can jack-up ring magnet 104 and push rod 107.Handwheel 110 outsides also are provided with a pressing plate that prevents to come off 111.
During work, mandrel 102 is connected with vidicon camera or photographic camera, shell 101 is connected with tripod, along with the adjustment of angle of shooting, mandrel 102 can produce rotation.Owing to have magnetic attracting force between annular iron plate 103 and the ring magnet 104, can produce the rotation that certain damping force stops mandrel 102.Utilize handwheel 110 can adjust the distance between annular iron plate 103 and the ring magnet 104, thus the size of control magnetically damped power.Because the active force in magnetic field does not rely on parts to be in contact with one another; So, in the device of present embodiment, even the wearing and tearing of some positions occurred; Can not have influence on the size of magnetically damped power yet, thus the adverse effect that can greatly reduce wear the angle of shooting balance caused.
Embodiment two
Similar with embodiment one, present embodiment also is to have adopted magnetic attracting force between ring magnet and the annular iron plate as the source of damping force, and difference is the arrangement of ring magnet and annular iron plate.
As shown in Figure 4, in the magnetomechanical damping The Cloud Terrace balance regulator of present embodiment, be provided with annular iron plate fixed plate 208 with the key ways of connecting on the mandrel 202, annular iron plate 203 is fixedly installed on this annular iron plate fixed plate 208.Carriage 206 is set near the end of mandrel 202 through bearing 205, is equipped with the adjusting screw rod 207 that four edges circumferentially are uniformly distributed with on it, as the damping adjustable lever.Be arranged with ring magnet fixed plate 209 with the gap ways of connecting on the mandrel 202, ring magnet 204 is fixedly installed on this ring magnet fixed plate 209.Annular iron plate fixed plate 208 is between carriage 206 and ring magnet fixed plate 209.Ring magnet fixed plate 209 is provided with four lugs 210 corresponding to adjusting screw rod 207, is threaded between adjusting screw rod 207 and the lug 210.Also be provided with the shell 201 of a tubular in the annular iron plate 203 and ring magnet 204 outsides; These shell 201 interior sliding-grooves that offer axial perforation corresponding to the position of lug 210; So that hold adjusting screw rod 207, can also prevent that ring magnet fixed plate 209 is along with mandrel 202 rotates together simultaneously.The termination of mandrel 202 is passed carriage 206 and is linked to each other with fixing frame 211.
During work, vidicon camera or photographic camera are fixed on the fixing frame 211, when adjusting angle of shooting like this, mandrel 202 will rotate thereupon, and magnetically damped power can limit this rotation.Adjust the size that spacing between ring magnet 204 and the annular iron plate 203 just can be adjusted magnetically damped power through four adjusting screw rods 207.
The benefit of this structure is that annular iron plate 203 all is convenient for changing with ring magnet 204, is beneficial to maintenance, also is beneficial in same device and satisfies different use needs through the annular iron plate 203 of changing different size with ring magnet 204.
More than the disclosed more excellent specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
