Description
Technical field
The utility model is related to support, more specifically to the jack column for supporting multiple objects.
Background technology
During photography, user is often supported to photographic equipments such as camera, video cameras using support, from
And lift the stability of photographic equipment.The support of similar structures can also be used to support telescope, microphone and gun etc.,
And the support of similar structures all plays the effect of improving stability.Support, while improving stability, can also change quilt
Supporting object terrain clearance, and in order to realize above-mentioned functions, support generally adopts telescopic structure design.Existing telescopic
Support includes the frame leg of varying number according to different demands, and every frame leg is adjustable telescopic frame leg, using the time-division
Do not adjust the length of every frame leg.For example, most commonly seen jack column includes three frame legs, if on flat ground
Using jack column, need to adjust three frame legs respectively to equal length, manual regulation error unavoidably, three frame legs hold
Situation different in size, the stability of impact jack column easily occur.In some cases, user need to adjust telescopic
To specific height, to reach the specific function of supported object, the such as terrain clearance by changing camera changes and takes support
Scape or lighting angle etc., adjust jack column to certain height it is necessary to adjust three frame legs to length-specific, and due to three
Bar frame leg and ground are supported at an angle it is impossible to directly carry out accurate adjustment to the height of expansion bracket.Other one
Under a little situations, user needs frequently to change the height of jack column, and needs jack column reaching certain height
Stable supporting role can be played afterwards, existing jack column adjusts height every time and all must adjust three frame legs respectively
Length, in addition to above-mentioned accommodation accuracy problem, adjust complex operation, less efficient.Existing frequently-used telescopic
When frame uses on broken terrain, need the length adjusting each bar frame leg respectively to adapt to ground, problem is to adjust
Good jack column is only applicable to corresponding ground region, once transfer jack column to other places, then needs according to ground
Situation adjusts the length of each bar frame leg again respectively, and complex operation is less efficient.The flexible of existing frame leg is generally come in fact by buckle
Existing, buckle has locking and unblock two states, and when buckle is in locking state, frame leg cannot stretch, and is in regular length, card
Buckle when released state, can manual adjusting bracket leg length, first unlock buckle during adjusting bracket leg length, manual adjusting bracket leg is stretched
Long or shrink, determine after length again by snap lock.For the telescopicing performance of reinforcing frame leg, frame leg is generally stretched by more piece
Contracting bar nesting combines, and also has multiple buckles simultaneously, according to required length, needs in adjustable telescopic rod using one
Or multiple buckle carrys out adjusting bracket leg length.Its function, push type card is realized by the way of the many locking using pressing of existing buckle
Buckle structure is simple, but Long-Time Service easily occurs wearing and tearing and affects locking function.Existing jack column is in structure and behaviour
Make all to have in mode and much have place to be hoisted.
