5results about How to "Leveling precision" patented technology

The utility model relates to the technical field of surveying and mapping, in particular to an outdoor multifunctional surveying device which comprises a self-leveling support and a surveying unmanned aerial vehicle, and the surveying unmanned aerial vehicle is arranged at the top of the self-leveling support through a displacement guiding mechanism; the displacement guide mechanism comprises a vertical guide rod vertically arranged at the top of the self-leveling support, a rotating seat is rotatably arranged at the top of the vertical guide rod, a horizontal guide rod is horizontally arranged on the side portion of the rotating seat, the vertical guide rod and the horizontal guide rod are multi-stage telescopic rods, and a surveying probe set is arranged on the surveying unmanned aerial vehicle. The surveying unmanned aerial vehicle is restrained and guided through the vertical guide rod and the horizontal guide rod of the displacement guide mechanism, the operation difficulty of the unmanned aerial vehicle is reduced, and damage to the unmanned aerial vehicle due to misoperation is avoided; meanwhile, the unmanned aerial vehicle is restrained and guided by the displacement guide mechanism, the influence of outdoor wind power can be reduced or even avoided, precise hovering of the unmanned aerial vehicle is facilitated, and the measurement precision is improved.

The utility model relates to squatting pan technical field, and disclose an integrated self-levelling integrated squatting pan module, include: support leg, both sides of support leg are fixedly installed with angle steel bracket, the bottom of two angle steel bracket is fixedly installed with fixed support, the bottom of two fixed support is installed with two squatting pan bodies, the dismounting subassembly includes the installation groove on two squatting pan bodies and is fixedly installed two plug -in boards at two fixed support bottom, plug -in board sliding installation in the inside of installation groove, the utility model discloses the setting of dismounting subassembly can adopt the assembly type steel support, installs standardization, shortens the construction period, reduces the cost, can be accurate with the closed deodorization combination simultaneously, promotes the use performance of squatting pan, improves the bathroom environment, and the design is general, can adapt to different public building bathroom demand, is convenient for pipeline overhaul, reduces the cost.

The utility model relates to the technical field of assembly type buildings, in particular to an assembly type built-in connecting piece and an assembly type built-in hanging plate connecting device. The fastener is used for connecting and fixing the fastener and a wall and comprises a first connecting piece and a second connecting piece, the first connecting piece integrally extends into the wall and is fixedly connected with the wall, a screw hole is formed in the end, away from the wall, of the first connecting piece, and one end of the second connecting piece penetrates through the fastener, extends into the screw hole and is in threaded connection with the first connecting piece. The screwing process of the second connecting piece and the first connecting piece is easy to control, it is guaranteed that the second connecting piece and the first connecting piece are located at the proper position, then the fastener can be accurately leveled, and therefore it is guaranteed that the hanging plate is stably installed on the fastener subsequently.

The utility model discloses a clothes hanger lifting leveling structure which comprises an airing rod assembly and a suspension rope, a traction piece is arranged on the suspension rope, the traction piece is provided with a vertically-arranged threaded hole, a bolt is arranged in the threaded hole, a base is arranged on the airing rod assembly, a first through hole is formed in the base, a bolt rod of the bolt is located in the first through hole, and a bolt head is located below the base. The airing rod assembly is provided with an adjusting channel communicated with the outside and the bolt head. And the adjusting channel is arranged below the bolt head, so that a user can use a tool to rotate the bolt through the adjusting channel, the operation convenience and accuracy are further improved, meanwhile, the bolt head is protected against external interference, and the service life is prolonged. And the bolt head is positioned below the base and is exposed in a space below the airing rod assembly without an adjusting channel. The length of the hanging rope can be conveniently adjusted, the problem that the hanging rod assembly is inclined due to the fact that the lengths of the hanging ropes of the electric clothes hanger are inconsistent is effectively solved, and the electric clothes hanger has the advantages of being easy to operate and accurate in leveling.

The invention discloses a tool and method for machining a pin hole of a position marker, and solves the technical problems that the precision of machining the pin hole by a manual electric drill is low, the machining period of machining the pin hole by adopting a five-axis machining center is long, the requirement on the technical level of an operator is high, the machining efficiency is low, the large-batch production requirement is difficult to meet, and the production cost is high. The position marker pin hole machining tool comprises a base, a supporting rod, a leveling ejector rod, two upper pressing blocks, two side pressing blocks and four axial positioning pins, the outer frame is limited through the supporting rod, the inner frame is limited through the leveling ejector rod, meanwhile, the plane where the top face of the inner frame is located is parallel to the plane where the mounting platform is located by rotating the leveling ejector rod, and the position marker pin hole machining tool is formed. The leveling mode is simple and fast, finally, accurate axial limiting position adjustment is conducted on the alignment marker by rotating the screws on the side pressing blocks, the adjustment precision is high, operation is convenient and fast, and the pin hole machining time period is shortened.
