A kind of spirit level and tripod thereon
Technical field
The present invention relates to total powerstation support technology field, more particularly to a kind of spirit level and tripod thereon.
Background technology
Spirit level is to set up the instrument that horizontal line of sight determines the ground point-to-point transmission discrepancy in elevation.Principle is to be surveyed according to measurement of the level principle Measure the discrepancy in elevation between ground point.Critical piece has telescope, pipe spirit level(Or compensator), vertical axis, pedestal, foot screw.
The Chinese patent that Authorization Notice No. is CN205859537U, the applying date is on May 31st, 2016 discloses a kind of survey Paint instrument tripod, including head is installed, the support bar that many one end are hinged with the installation head, the support bar it is another End is rotatably connected to a positioning disk with many mounting rods, and many mounting rod front ends distributions, which are connected with, different to be used to support Align member on the ground is connect, is provided for positioning the positioning disk between the support bar and the positioning disk in the branch The positioning component of position on strut.
Wherein, because three support bars need to be controlled respectively so that need once to open when in use and go forward side by side The adjustment of row difference, not only needs to adjust the size that every support bar opens, and needs to carry out the regulation of length for environment, It is relatively complicated.
The content of the invention
The purpose of the present invention one is to provide a kind of tripod, and it, which has, facilitates tripod to use, the effect of convenient regulation.
The present invention above-mentioned technical purpose one technical scheme is that:
A kind of tripod, including pedestal and some supporting legs, the bottom of the pedestal, which is vertically installed with a screw mandrel, the screw mandrel, to be set It is equipped with sliding sleeve, the sliding sleeve and is rotatably connected to a ballscrew nut fitting being connected with wire rod thread, the supporting leg and sliding sleeve Between be hingedly connected with pull bar;Ballscrew nut fitting turn can unidirectionally be limited by being provided between the sliding sleeve and ballscrew nut fitting Dynamic commutation ratchet mechanism.
It is arranged such, by ballscrew nut fitting and screw mandrel formation lead screw transmission mechanism, simultaneously as using rolling Ballscrew pair of nut, and connection is rotated between ballscrew nut fitting and sliding sleeve, when opening, drawing supporting leg in, pull bar can be in sliding sleeve It is upper to produce corresponding power up or down, i.e., power up or down is produced on ballscrew nut fitting, now active force Ballscrew nut fitting can be driven to rotate, and simultaneously drive slide on screw mandrel slide, by pull bar connect sliding sleeve and Supporting leg so that opening for supporting leg is consistent in the presence of sliding sleeve and pull bar.
More preferably, the commutation ratchet mechanism includes:
One ratchet, is integrally formed on lifting nut outer wall;
One shifting block, is embedded in sliding sleeve, is provided with positive pawl and anti-ratchet, and the pawl point of the positive pawl and anti-ratchet is relative Set;
One toggle, for stirring shifting block to control positive pawl/anti-ratchet to be engaged with ratchet.
It is arranged such, shifting block is stirred by stirring toggle, controls positive pawl or anti-ratchet to be engaged with ratchet with this, from And the one direction to ratchet is defined, one-directional rotation and the commutation of ratchet are realized.
More preferably:It is provided with the sliding sleeve and is embedded chamber for installing the arc of shifting block.
It is arranged such, it is spacing to shifting block progress, it is slightly moved, and be embedded when being engaged with ratchet by arc The side wall formation one-way check of chamber, starts to the unidirectional spacing of ratchet.
More preferably:The shifting block is in crescent shape, and its back side is provided with the allocating slot of arc;Set on the toggle There is a driving lever, one end of the driving lever is connected on the allocating slot of shifting block.
It is arranged such, when stirring toggle, drives driving lever to be moved in allocating slot, so as to promotes shifting block to occur small size pendulum It is dynamic, realize the replacing that positive pawl and anti-ratchet are engaged with ratchet.
More preferably:The rotating shaft set along screw mandrel direction of axis line is provided with the toggle, the driving lever is vertical It is arranged in rotating shaft.
It is arranged such, by rotating toggle come rotating shaft, so that drive driving lever to rotate around the shaft, and then promotion is dialled Small size swing occurs for block, realizes the replacing that positive pawl and anti-ratchet are engaged with ratchet.
More preferably:The toggle is fixed on a worm screw, and the driving lever is located at an axial line and screw mandrel axial line On parallel turbine, the worm screw engages with turbine.
It is arranged such, the swing of driving lever is controlled by turbine and worm, realizes what positive pawl and anti-ratchet were engaged with ratchet Change, in addition, it reversely can only can not promote driving lever to swing by unidirectional control, shifting block.
More preferably:The driving lever is an elastic telescopicing rod.
It is arranged such, the positive and negative ratchet on shifting block can play a part of unidirectional spacing ratchet, but simultaneously, unavoidably Ratchet still can cause resistance to the rotation of ratchet, and by the setting of elastic telescopicing rod, can effectively reduce the resistance of generation Power.
More preferably:The two ends of the sliding sleeve are connected by bearing with ballscrew nut fitting, the ratchet position Between two bearings.
It is arranged such, realizes that the rotation between sliding sleeve and ballscrew nut fitting is connected by the setting of rotating shaft.
The purpose of the present invention two is to provide a kind of spirit level.
The present invention above-mentioned technical purpose two technical scheme is that:
A kind of spirit level, including inspection apparatus and above-mentioned tripod, the inspection apparatus are installed on the pedestal of tripod.
In summary, the invention has the advantages that:It can realize that multiple supporting legs synchronize opening and closing Operation, and by the setting for the ratchet mechanism that commutates, unidirectionally spacing can be carried out to supporting leg so that it can stablize when in use It is placed on the ground, and supporting leg can be avoided to open when not in use.
