Abstract

The utility model relates to a multipurpose building line plumb, which belongs to a construction tool. The line plumb is a cone; the geometric center of the bottom plane of the cone is connected with a line handle; the center of the line handle has a through hole. The multipurpose building line plumb is characterized in that the geometric center of a plumb body has a blind hole; the geometric center of a plumb head has a through hole; a plot pen is connected to the through hole of the plumb head; the plumb head and the plumb body are connected. The multipurpose building line plumb can draw out a measured or positioned point at the same time measuring and positioning. When the multipurpose building line plumb is not required to draw out the measured or positioned point, the upper end of the plumb body is provided with a solid plumb head. The line plumb has simple structure, convenient operation and labor saving. When the plot pens of different color are used, different drawing effects can be achieved.

Description

How to weigh down with building line

The utility model relates to a kind of building operation instrument, and specifically building line weighs down.

At present, when the survey axis was drawn in building operation, it was a round metal cone that employed line weighs down, and the geometric center in round metal cone baseplane connects wired carrying, and there is a through hole at the center that line is carried; With on the face that the baseplane is connected a semicircle indent is arranged.During use, threading in the online through hole of carrying the center, portable this line is inverted the round metal cone, and promptly line weighs down and just can do to measure or the location use.Weigh down the point of measuring or locating with this line, need an other people that the point measured or location is depicted with red, orchid, wasted manpower and used inconvenient.

The purpose of this utility model is that a kind of save manpower and easy to use manyly weigh down with building line will be provided.

The purpose of this utility model is achieved in that this line weighs down by weighing down body and weighing down head and forms, and the geometric center of weighing down body has blind hole, and weighing down several leading what center has through hole, weighs down in the through hole of head to be connected with tracer, weighs down head and weighs down body and be connected formation one cone after the connection.

In the such scheme because line weighs down by weighing down body and weigh down head and forms, measure or the location in depict again and measure or during the point of location, as long as be with the bob head of tracer by dress weighing down the body front end; When the point that does not need to describe to measure or locate,, reached the novel purpose of this reality weighing down the body front end by adorning solid bob head.This line weighs down simple in structure, easy to use, has saved the labour, when using the tracer of different colours, can reach the different effects of describing.

Be described further in conjunction with the embodiments with reference to the accompanying drawings below.

Accompanying drawing is the novel structural drawing of this reality.

Embodiment: this line weighs down by weighing down body 2 and weighing down 5 and forms, and bob body 2 is a Rotary-table, and the blind hole 3 of indent is arranged in Rotary-table roundlet table top geometric center; The geometric center connection of big round table surface is wired carries 1, line is carried 1 center a through hole, line carry 1 with face that big round table surface is connected on a semicircle indent is arranged, weighing down 5 is cone, weigh down a geometric center of 5 through hole is arranged, be connected with tracer 4 in the through hole of bob head, the nib of tracer 4 protrudes and is the summit of cone; Pen portion after one's death insert to weigh down in the blind hole of body 2, when the point that does not need to describe to measure or locate, is weighing down body 2 front ends by adorning solid bob 5, weigh down 5 with weigh down body 2 and be connected formation one level and smooth cone after connecting.Threading in the online through hole of carrying 1 center during use, portable this line-cone body will be inverted, the cone summit is downward, measure or the location after can directly on determined point, depict mark.

Claims

1, a kind of how the bob with building line, line weighs down and is cone, geometric center in the baseplane of cone connects wired carrying, there is a through hole at the center that line is carried, it is characterized in that: the geometric center of weighing down body has blind hole, weighing down several leading what center has through hole, weighs down in the through hole of head to be connected with tracer, weighs down head and is connected with the bob body.

2, according to claim 1 many with the building line bob, it is characterized in that: described bob is as Rotary-table; Weighing down head is cone.

3, according to claim 1 many with the building line bob, it is characterized in that: the described bob head that is connected with the bob body can be solid bob head.
