Description

A kind of levelling rod for the measurement of the level

Technical field

The utility model relates to measurement of the level technical field, in particular to a kind of levelling rod for the measurement of the level.

Background technique

Level is the instrument for establishing horizontal line of sight measurement ground point-to-point transmission height difference.Generally in level use process, It needs to place levelling rod on the ground and carries out mating measurement.The scale used when levelling rod is the measurement of the level, it is with good wood The materials such as material or glass reinforced plastic, aluminium alloy are made.Level ruler is long to be generally 3m, and two secondary for one, and is two-sided (black, red face) The ruler of scale is printed with black and white or graduation red and white every 1cm.

Existing levelling rod is generally stood on ground by the hand steered mode of construction personnel, then reads personnel from level Eyepiece on read levelling rod reading.But levelling rod needs to keep vertical in use as a kind of precision instrument State.Construction personnel manually helps levelling rod to will lead to oblique leveling staff, causes measurement data deviation big.

Utility model content

The purpose of the utility model is to provide a kind of levelling rods for the measurement of the level, are supported by being arranged on blade Bar has achieved the effect that fixed blade.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of levelling rod for the measurement of the level, including blade, the opposite sides on the blade are scale face, the ruler Another two sides with it are blank face, and sliding block is provided in two blank faces, and the sliding block is sliding along the length direction of blade Dynamic cooperation；The locking bolt being threadedly engaged with it is equipped on the sliding block, one end of the locking bolt is pushed against in the sky On fine flour；Several support rods are rotatably connected on the sliding block.

By adopting the above technical scheme, rotary supporting rod is supported on it on ground, so that the position of fixed blade, reduces people The case where work support causes measurement accuracy to decline.In use, unscrewing locking bolt and slide downward sliding block, so that the length of support rod Degree is greater than the distance of sliding block to blade bottom.Rotary supporting rod to form certain angle between support rod and vertical blade simultaneously Degree, and support rod bottom is pushed against on ground.Then locking bolt is tightened, fixed sliding block is in the relative position of blade.

Further preferably are as follows: two support rods are provided on each sliding block, described support rod one end passes through ten thousand It is rotationally connected on the sliding block to wheel.

By adopting the above technical scheme, any angle is capable of forming between support rod and sliding block, to improve the branch of support rod Effect is supportted, the stability of blade is reinforced.

Further preferably are as follows: one end on the support rod far from sliding block is rotatably connected to conflict plate, the conflict plate Area is greater than the section of the support rod.

By adopting the above technical scheme, increase the contact area between support rod and ground, to improve the support of support rod Effect.It is rotationally connected on support rod due to contradicting plate, conflict plate is all contacted with ground.

Further preferably are as follows: described one end contradicted on plate far from the support rod, which is fixed with, grabs plot, described to grab plot Section from contradict plate on to far from contradict plate direction in reduce setting.

By adopting the above technical scheme, the connection effect for contradicting plate and ground is further increased, to improve the branch of support rod Support effect.When the ground of measurement is soil layer, grabbing plot can be plugged into soil layer, improve the support effect of support rod.

Further preferably are as follows: described grab has additional raised line far from the side for contradicting plate on plot.

By adopting the above technical scheme, the frictional force grabbed between plot and ground is improved, to enhance support rod to blade Support effect.

Further preferably are as follows: the support rod includes the first rod piece being connected on sliding block and is embedded at first rod piece The second internal rod piece；First rod piece and the coaxial arrangement of the second rod piece, and second rod piece is matched along the sliding of the first rod piece It closes；It is equipped with the fixing bolt being threadedly engaged with it on first rod piece, one end of the fixing bolt is pushed against in described the On two rod pieces.

By adopting the above technical scheme, the length of support rod is adjusted, it can be between blade so as to expand support rod The angular range of formation, to expand the scope of application of levelling rod.

Further preferably are as follows: mounting groove, length direction of the mounting groove along the blade are offered in the blank face Perforation opens up；The sliding block is set in the mounting groove, and is placed in the mounting groove after support rod rotation.

By adopting the above technical scheme, it when being protected to sliding block and support bar top, and not using levelling rod, can utilize Mounting groove stores support rod.

Further preferably are as follows: the side of the mounting groove inner wall is fixed with fixed rope, and opposite the one of the mounting groove inner wall Side has additional fixation kit, for fixing hanging one end of fixed rope.

By adopting the above technical scheme, it further facilitates and support rod is stored, reduce support rod and dropped out from mounting groove The case where occur.

Further preferably are as follows: the fixation kit includes the trough plate being fixed on the mounting groove inner wall, the flute profile The notch of plate is arranged towards fixed rope；The hanging one end of the fixed rope is provided with fixed plate, offers in the fixed plate logical Hole；The notch of the fixed plate and trough plate is mating, and the first spiral shell being threadedly engaged with it is equipped on the trough plate Bolt, first bolt pass through the through-hole and push against on the trough plate.

By adopting the above technical scheme, when needing for support rod to be accommodated in inside mounting groove, rotary supporting rod is located at In mounting groove.Then fixed plate is inserted into the notch of trough plate, tightens the first bolt and passes through through-hole and push against in slot On shape plate；It is easy to operate.

Further preferably are as follows: spirit level is had additional in the blank face, plane is perpendicular to the ruler where the spirit level The length direction of body.

By adopting the above technical scheme, convenient that blade is leveled, so that blade is in a vertical state, it is accurate to improve measurement Degree.

In conclusion the utility model has the following beneficial effects: by the fixed blade of setting support rod, reduction is manually helped The case where water holding object staff causes measurement accuracy to decline.
