Abstract

A multifunctional plumb bob for building survey comprises a reverse taper plumb bob body and a liftinglug arranged at the central position of the upper end of the plumb bob body. The plumb bob is arranged to be an upper and a lower segments. An axial blind hole is arranged at the center of the bottom of the upper plumb bob; an axial via hole is arranged at the center of the lower plumb bob and the hole is equipped with a drawing pen. A clip spring is arranged at the joint of the upper and the lower plumb bob bodies; the upper and the lower plumb bob bodies are connected by thread. When measuring, a tie wire is carried by hand to enable the plumb bob to droop; the drawing pen arranged at the top end of the cone can draw directly when survey point is needed to be marked by the pen. The device saves manpower and the drawing pen arm can be fixed by the clip spring arranged at the joint of the upper and the lower plumb bob bodies and convenient for drawing.

Description

A kind of construction account is many to be weighed down with line

Technical field

The utility model relates to a kind of building operation instrument, and especially a kind of line of measuring the buildings verticality weighs down.

Background technology

In the prior art, employed line bob is the back taper metallic object of an integral body when drawing the survey axis in the building operation, and planar central is provided with hanger on metallic object, threading in hanger, and it is sagging that portable this line also weighs down line, can measure buildings.This instrument is convenient and practical, but shortcoming be measure or the location after, need an other people to measure and mark with pen, waste time and energy and inconvenient.

Summary of the invention

The purpose of this utility model provide a kind ofly collect measurement, indicate one, save manpower, easy to use manyly weigh down with line.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: many falling body that comprises back taper and the hangers that are arranged on center, falling body upper end of weighing down with line of this construction account, described falling body is set to upper and lower two sections, bottom center at last falling body is provided with axial blind hole, center at following falling body is provided with axially extending bore, and ruling pen is housed in the hole; Upper and lower falling body is connected by screw thread.

Junction at upper and lower falling body also is provided with cavity, and jump ring is housed in cavity, and the penholder of ruling pen contacts with jump ring.

Described jump ring comprises that deck and two ends are the steel wire of symmetric curvature, and fixation with steel wire is on deck, and the two ends of steel wire contact with the penholder of ruling pen respectively.

The cylindrical and the endoporus of described deck all are upturned respectively, and the coboundary of cylindrical perk bends inwards, and the steel wire middle part is stuck in the groove of bending back formation; Symmetria bilateralis at the hole wall of endoporus perk is provided with breach, and the two ends of steel wire are stuck in indentation, there, and the distance between the steel wire two ends is less than the diameter of drawing penholder.

Because falling body is set to removable upper and lower two sections, and is equipped with ruling pen in falling body, will measure when marking and can directly describe at needs with pen, saved manpower.The jump ring that is arranged on upper and lower falling body junction can be fixed the drawing penholder, is convenient to describe.

Embodiment

Many falling body that comprises back taper and the hangers 1 that are arranged on center, falling body upper end of weighing down with line of this construction account, described falling body is set to upper and lower two sections, bottom center at last falling body 2 is provided with axial blind hole, center at following falling body 3 is provided with axially extending bore, blind hole is corresponding with through hole, and ruling pen 4 is housed in the hole.Be respectively arranged with screw thread on the position that last falling body 2 and following falling body 3 are worked in coordination, upper and lower falling body is connected by screw thread.For ruling pen being fixed in the falling body hole, also be provided with the cavity of diameter in the junction of upper and lower falling body greater than the falling body hole, in cavity, be provided with jump ring, the penholder of ruling pen 4 contacts with the jump ring endoporus.Described jump ring comprises that deck 5 and two ends are the steel wire 6 of symmetric curvature, and steel wire 6 is fixed on the deck 5, and deck 5 is fixed on the bottom surface of falling body 2, and the two ends of steel wire 6 contact with the penholder of ruling pen 4 respectively.In the present embodiment, described deck 5 is sheet metals of a ring-type, by pressing and fixing in the cavity of last falling body 2 and following falling body 3 junctions, the cylindrical of thin slice and endoporus all upwards bend perk respectively, and the coboundary of cylindrical perk bends inwards again, and the middle part shape of steel wire 6 is corresponding with the cylindrical of deck 5 and be stuck in the groove that cylindrical bending back forms.The center curvature that the two ends of steel wire 6 correspond respectively to deck 5 becomes parallel U-shaped.The diameter of deck 5 endoporus is a bit larger tham the penholder diameter of ruling pen 4, upwards bend at deck 5 endoporus on the inner hole wall of symmetrical both sides of perk place and be respectively arranged with breach, the two ends of steel wire 6 are stuck in indentation, there and contact with the side of hole wall, and hole wall plays position-limiting action to the elasticity two ends of steel wire 6.In order to make steel wire to penholder certain holding force be arranged, the distance between steel wire 6 two ends is less than the diameter of drawing penholder.When the two ends of steel wire 6 contacted with the penholder of ruling pen 4, penholder can make the two ends of steel wire 6 leave the hole wall side.

In addition, the curved shape at the two ends of steel wire 6 can also be set to the semicircular arc with respect to deck 5 center curvatures, this moment, the peak of semi arch was stuck in the indentation, there that deck 5 endoporus hole wall both sides are provided with, and can clamp penholder when the penholder with ruling pen 4 contacts.

During measurement, it is sagging that portable backguy is weighed down line, and the ruling pen that is arranged on the cone tip can will be measured when marking with pen at needs and directly describe, and save manpower.The jump ring that is arranged on upper and lower falling body junction can be fixed the drawing penholder, is convenient to describe.
