Abstract

The utility model relates to a shock absorbing holder for a zoom and ultra-long focus lens, which is composed of a main bracket, a camera bracket, etc., wherein the front side of the main bracket is fixedly connected with an external sleeve pipe which is connected with an internal sleeve pipe in a sliding mode; the external sleeve pipe is fixed with a fixed support on which an elastic control knob of the front sleeve pipe is arranged; the other end of the internal sleeve pipe is fixed with a base of a front bracket, a bracket of a lens tube is arranged on the front bracket and a movable gravity center bracket on which a gravity center control button is arranged is installed on the internal and the external sleeve pipes. The utility model has the advantages that a camera and the holder can keep balance at any time, and the shock absorbing holder for a zoom and ultra-long focus lens which is free from the limitation of lenses with various focuses can be conveniently used.

Description

Zoom and the shockproof The Cloud Terrace of overlength focal length lens

The utility model is a kind of zoom and the shockproof The Cloud Terrace of overlength focal length lens, is used in use shockproof of zoom and overlength focal length lens, belongs to photographic equipment.

The Cloud Terrace on the traditional triangle frame is used for the fixing of fuselage more, and the fixing threaded hole that also has the overlength focal length lens to be connected with The Cloud Terrace designs the mode under lens barrel.The former is suitable for this dual mode the short-focus mirror head, and the latter is suitable for telephoto lens.But the former is that the camera lens damping effect of traditional The Cloud Terrace centering long focus is undesirable; Though the latter is applicable to the damping of overlength focal length lens, because of camera unsettled (nowhere fixing), vibratory source is again in fuselage interior, so when shutter rose and fell, the fuselage vibrations were unavoidable, picture also is difficult to the higher clearness of acquisition.In order to solve an above-mentioned difficult problem, wise professional photographer often carries two tripods, with the professional egative film that obtains amplifying for big ratio.So, the vibration problems of fuselage is to have solved, but weight has increased again.At various length focal length lenses of modern times, various additional eyeglasses and professional film itself is with regard under the very heavy situation, and travelling is incogitable especially at a distance to carry two tripods, but not so can't be closed fully in the egative film of the fine definition that requires again.

The purpose of this utility model is just in order to solve deficiency of the prior art, and proposed a kind of zoom and the shockproof The Cloud Terrace of overlength focal length lens.This The Cloud Terrace can be supporting with former tripod, and center (center of gravity) point directly is screwed on the The Cloud Terrace of former tripod gets final product.The very firm easy accent of this The Cloud Terrace.

The purpose of this utility model is achieved in that

Zoom and the shockproof The Cloud Terrace of overlength focal length lens are made up of master carrier, camera carriage, camera lifting control knob, camera lifter rack and camera retaining screw etc.At the fixedly connected outer sleeve in the front of master carrier, what be slidingly connected with outer sleeve is inner sleeve, on outer sleeve, fix a fixing holder, in the fixing holder anterior cannula degree of tightness control knob is arranged, fix a forestock stand at the other end of inner sleeve, the barrel carriage is installed on front rack, a movably center of gravity holder is installed on internal and external casing, the center of gravity control knob is arranged in the center of gravity holder.

The utility model has three width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.

Fig. 1, be stereo rearview of the present utility model;

Fig. 2, be planimetric map of the present utility model;

Fig. 3, be sectional side view of the present utility model;

Fig. 4, be locking device figure of the present utility model.

The utility model advantage compared with prior art is: camera and The Cloud Terrace are kept at any time Balance is not subjected to the restriction of various different focal camera lenses; 2, can directly be screwed on the The Cloud Terrace of former tripod, Easy to use; 3, simple in structure.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further:

Most preferred embodiment of the present utility model is shown in Fig. 1,2,3,4, and zoom and the shockproof The Cloud Terrace of overlength focal length lens are made up of master carrier 3, camera carriage 7, camera lifting control knob 9, camera lifter rack 13 and camera retaining screw 8 etc.The fixedly connected outer sleeve 1 in the front of master carrier 3, what be slidingly connected with outer sleeve 1 is inner sleeve 2, on outer sleeve 1, fix a fixing holder 5, in the fixing holder 5 anterior cannula degree of tightness control knob 11 is arranged, fix a forestock stand 6 at the other end of inner sleeve 2, barrel carriage 12 is installed on front rack 6, a movably center of gravity holder 4 is installed on internal and external casing, center of gravity control knob 10 is arranged in the center of gravity holder 4.Lifting control knob 9 joins with axle 18, fixedly connected teeth wheel 16, projection 17 on the axle 18, and corresponding with it gong silk 14 is by knob 15 controls.

In use,, be screwed to by following screw on the The Cloud Terrace of tripod, adjust length with outer sleeve 1 inner sleeve 2 that be slidingly connected, telescopic according to the length of camera lens with movably center of gravity holder 4.Adjust suitable after, tighten the anterior cannula degree of tightness control knob 11 in the fixedly holder 5 that is fixed on the outer sleeve 1, make inner sleeve 2 and outer sleeve 1 fastening.Camera is fixed on the camera retaining screw 8 on the camera carriage 7, and telephoto lens is held up by the barrel carriage on the front rack 6 12, and the height of camera can be regulated lifter racks 13 by camera bracket lifting control knob 9 and realize.Regulate lifting control knob 9, camera is risen to needs height, regulates 15 immediately, withstands the axle 18 of teeth wheel 16 later on by 14 gong silk precessions, therefore, has formed an opposite moment by 14 and 17, then tooth bar 13 lock (Gu) decide.Finish by the outer sleeve 1 and the adjusting of center of gravity holder 4 at the center of camera (center of gravity), after center of gravity is found accurately, tightens fixedly center of gravity of center of gravity control knob 10.

The utility model result of use is good, and is simple in structure, and easy operating is suitable for promoting the use of.
