Abstract
The utility model relates to a movable mounting rack for adjusting the position of a camera test chart, which solves the problems that the traditional test chart is fixed on a wall body and thus cannot move, and the camera test chart is generally inconvenient to use during installation due to factors of angle light. The movable mounting rack comprises bases, support posts and a chart mounting frame, wherein two ends of the support post are fixed to the base and the chart mounting frame; the chart mounting frame is an annular framework; a through hole in which the test chart is inserted is arranged on the lateral surface of the chart mounting frame; and a fastening device is arranged on the side edge of the chart mounting frame. The movable mounting rack has a simple structure; the test chart is quite conveniently mounted and dismounted and is firm after being mounted; the base can be horizontally adjusted and can freely move; and the utilization rate of the space of a test field is doubly improved.
Description
Technical field
The utility model relates to a kind of movable scaffold, relates in particular to a kind of movable scaffold that is used to regulate photographic camera test chart position.
Background technique
Generally when using the photographic camera test chart,, all can select to be fixed to be installed on the metope because its build is bigger.As distort test chart and resolution test target, at this moment just need be to the requirement of carrying out test site than higher, at first just needing can be for the roomy body of wall of installing, and the position of body of wall must meet the requirements, secondly two test charts also need to take certain place, space, and cost is higher.
Summary of the invention
The utility model has mainly solved: after test chart is fixed on the body of wall, do not possess mobility, the photographic camera test chart is installed regular meeting often because the factor affecting of angle light causes and uses inconvenience carrying out, also often need body of wall of building simultaneously, make cost improve; A kind of movable scaffold of photographic camera test chart that can be free movable is provided.
The technical solution adopted in the utility model is: the movable scaffold of photographic camera test chart, comprise base, supporting post, target installing frame, the two ends of supporting post are fixed on base and the target installing frame, described target installing frame is an annular frame, its side has and is used for the through hole that test chart inserts, and the incline of target installing frame is provided with securing means.
The movable scaffold of this photographic camera test chart can adopt lightweight material, like this behind the installation testing target, can random as required moving, and move conveniently.
As preferably, the base lower end is provided with three pulleys at least, and pulley is a universal wheels.
Pulley is installed under the base, can make things convenient for moving of the movable scaffold of photographic camera test chart, particularly universal wheels.
As preferably, securing means is a clamping bolt, and described incline is provided with a plurality of clamping bolts.
After in test chart inserts the target installing frame, the end of test chart is fixed, so just can be played the effect of fixing test target with clamping bolt.
As preferably, also be provided with level(l)ing mechanism between pulley and the base.
As preferably, described base is provided with leveling instrument.
By the use of level(l)ing mechanism and leveling instrument, can regulate the flat horizontal stroke of photographic camera test chart travel(l)ing rest.The horizontal adjustment structure can be fixed plate and the movable bolt that is fixed on the fixed plate, and pulley is fixed on down fixing, and the bolt head of movable bolt is fixed on the fixed plate, and bolt shank is connected with whorl of base, in order to regulate the vertical spacing of fixed plate and base.
As preferably, be provided with auxiliary rod between described supporting post and the base, auxiliary rod is symmetrical arranged about supporting pillar.
Auxiliary rod plays reinforces the supporting post function.
The beneficial effect that the utility model is obtained is: the utility model is simple in structure, and the test chart installing/dismounting is all very convenient, and is very firm after the installation, and base can horizontal adjustment, and can move freely, and significantly improves the test site utilization of space.
