Description
Technical field
The utility model relates to survey instrument field, and more particularly, it relates to a kind of levelling staff bracket.
Background technology
In tight measurement of the level under various conditions, especially in route leveling, generally by staffman's hand steered levelling staff from start to finish, the delineation numerical value that spirit-leveling instrument reads levelling staff under the state of sight line level is operated by observation person, require in observation process that levelling staff is in vertical steady state (SS) all the time, and then reading exact numerical, but staffman helps easy fatigue for a long time, and slight skew can occur scale in support process, secondly calibration process needs 3 people to complete suitable disabled person's power.
For solve above-mentioned application number be 201020128556.6 Chinese patent disclose a kind of levelling staff bracket, eliminate artificial demand of helping scale, scale is fastened by the semiclosed cover arranged, although solve artificial support to cause fatigue and the problem affecting calibration accuracy, but the kind of scale has a lot of semi-enclosed cover card can only be applicable to suitable scale, if the length and width of scale can not blocks adaptation with cover overlap that block just cannot nonadjustable signal, in addition scale needs to insert cover card above cover card when fixing, first the very high installation and removal process of scale can be pretty troublesome.
Utility model content
For the deficiency that prior art exists, installation and removal that the purpose of this utility model is to provide a kind of levelling staff bracket to facilitate scale and the size of any scale can be applicable to.
For achieving the above object, the utility model provides following technical scheme:
A kind of levelling staff bracket, comprise support and scale, described support is removably connected with clamping body, described clamping body comprises clamping part and connecting portion, described clamping part comprises grip block and governor motion, described grip block offers groove, and described governor motion is threadedly connected to described grip block, and described governor motion carrys out the scale of adaptive different size for the width changing groove.
By technique scheme, scale to be stuck in groove and to be locked by governor motion, and the width that governor motion can change groove goes for the scale of different size, and installation and removal scale is convenient.
As preferably, the sidewall of described grip block offers threaded hole, described governor motion comprises compact heap, threaded post and rotating part, described threaded post is located between compact heap and rotating part, described threaded post is threadedly connected in threaded hole, described compact heap is placed in groove, and the rotation of described rotating part can change the distance between compact heap and grip block sidewall and be fixed scale.
By technique scheme, only need the width rotating rotating part just adjustable groove, and governor motion is threaded with grip block, is threaded and itself has auto-lock function, easy to adjust.
As preferably, described connecting portion is L-shaped fixture block, and described support comprises hack lever and fixed block, and described hack lever is articulated with fixed block, and described fixed block offers mounting hole, and described fixture block is connected in mounting hole.
By technique scheme, snap fit convenient disassembly, only need be connected on fixed block by fixture block when needs use, easy to operate.
As preferably, described rotating part comprises contiguous block, and described contiguous block is equipped with the body of rod.
By technique scheme, arranging of the body of rod reduces power required when rotating rotating part, increases the moment of rotating.
Compared with prior art, the advantage of levelling staff bracket described in the utility model is: the clamping that can be applicable to different model different size scale, and scale be installed on convenient disassembly.
