Abstract

The utility model discloses a laser positioner, which comprises a body and a laser seat, wherein the laser seat is fixed on the body through an adjustment bolt and is provided with a laser transmitter; and the middle part of the body is provided with open holes adapted to laser transmission, and the lateral surface of the body is provided with an adjustable bracket. The laser positioner has the advantages of: 1, taking laser as an alignment wire to quickly determine the central fixed point of each layer of sleeve only by finding out a centre point according to a top layer and a bottom layer, and having high working efficiency; 2, not swinging and realizing accurate positioning because the laser alignment wire has good linearity and good stability; 3, realizing unobstructed mounting because the laser alignment wire does not obstruct the operations of mounting the sleeves and pipe clips; and 4, having convenient use and being fixed on the inner wall of the sleeve by the bracket.

Description

A kind of laser positioning instrument

Technical field

The utility model belongs to the building location instrument, is specifically related to a kind of laser positioning instrument.

Background technology

During building Zai An Zhuan Give soil stack, first procedure is that floor sleeve pipe and pipe clamp were installed.Existing installation method is to use the method alignment of hanging directrix earlier, installs again.As the installation of sleeve pipe, find sleeve pipe mounting center position accurately at top layer, and the center fixation point is set, line is weighed down down hang from the center point of fixity, find out the sleeve pipe mounting center, directrix limit tubing is hung on the limit successively, finishes each a layer sleeve pipe on the perpendicular line at last and installs; The and for example installation of pipe clamp, find the pipe clamp installation site accurately at top layer, the center fixation point is set, the criterion upper end is fixed on the central point, then the line bob is winched to bottom from top layer and find central point accurately, and central point is fixed on apart from line with a small circle greater than the directrix diameter weighs down on the criterion at one meter, criterion can be moved up and down, when with the directrix being centre-drilling hole or installation pipe clamp, should remove directrix (at this moment line weigh down move upward) to one side realizes not having and falls construction, the directrix that resets after construction is finished (at this moment line weighs down and moves downward) is finished the installation of each layer pipe clamp on the perpendicular line.There is following shortcoming in existing installation method: the one, and the existence of directrix produces installation process and hinders, and can't pass through casing wall when particularly sleeve pipe is installed, and needing layer by layer respectively, messenger wire weighs down inefficiency; The 2nd, line weighs down swing greatly, and bearing accuracy is low, and consuming time.

The utility model content

It is accurate that the purpose of this utility model provides a kind of measurement, efficient height, laser positioning instrument easy to use.

Realize that the technical scheme that above-mentioned purpose adopts is: the laser positioning instrument comprises body, laser bench, laser bench is fixed on the body by set screw, laser bench is provided with generating laser, and the body middle part is provided with the perforate that adapts to Laser emission, and the body side is provided with adjustable support.

Described adjustable support is two section telescopic bar structures, between each bar spring is set, and can regulate the length of support by spring; Perhaps pass through the length of screw adjusted support; Perhaps be threaded, regulate the length of support by rotating extensible arm.

Further technical scheme is:

Adopt pyramidal structure to cooperate between described laser bench and the generating laser.

The outer end of described support is provided with the plastic material piece;

On described generating laser, increase the generating laser wireless remote control receiving device, increase generating laser wireless remote control emitter simultaneously;

Also comprise the laser positioning dash receiver, the laser positioning dash receiver adopts cross structure.

The support of this laser positioning instrument is used for body is fixed on the inwall of sleeve, can regulate its length according to the different inner diameters of sleeve pipe, the plastic material piece of the outer end of support can increase the friction make body more secure fixation on sleeve; Adjust set screw and make generating laser be positioned at the central point of sleeve pipe, and make the laser spots center that aims at the mark; Adopt pyramidal structure to be combined with between laser bench and the generating laser and be beneficial to the stable and centering of generating laser; The emission of generating laser wireless remote control, receiving trap are used for the duty of far distance controlled generating laser, as switch, timing or the like.

The utlity model has following advantage:

1, only need to find out central point according to top layer and bottom, promptly available laser is quick and precisely located each layer sleeve pipe, high efficiency as directrix;

2, because of the laser directrix has fine linearity and stability, can not swing accurate positioning, quick;

3, the laser directrix can not hinder sleeve pipe and pipe clamp fitting operation, can realize accessible installation;

4, easy to use, only needing to be fixed on internal surface of sleeve pipe with support can fix;

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

Embodiment

See Fig. 1 to Fig. 3, the laser positioning instrument comprises body 4, laser bench 3, laser bench 3 is fixed on the body 4 by set screw 2, laser bench 3 is provided with the generating laser 8 that contains power supply, generating laser 8 is provided with generating laser wireless remote control receiving device 1, laser bench 3 and generating laser 8 adopt pyramidal structure 9 to cooperate, body 4 middle parts are provided with perforate, generating laser 8 stretches out downwards from perforate, body 4 sides are provided with three length-adjustable supports, support is by two section telescopic bars 5,6 form expansion link 5, spring 10 is set between 6, and the outer end of expansion link 6 is provided with block rubber 7; Also comprise generating laser wireless remote control emitter 11 and cross laser location dash receiver 12.

Also can be between the expansion link 5,6 of support by the length of screw adjusted support, perhaps two expansion links 5,6 adopt and are threaded, by the length of rotating extensible arm 6 adjusting supports.

Use of the present utility model and principle of work are as shown in Figure 4, the laser positioning instrument is installed in building top layer 14 sleeve pipes 15, body 4 relies on elastic force to be fixed on sleeve pipe 15 inwalls by the expansion link in the support 6, block rubber 7 on expansion link 6 outer ends can make body 4 more firm, open generating laser wireless remote control emitter 11, generating laser 8 is by emission laser 13 after its wireless remote control receiving device 1 received signal, the cross laser that adjustment set screw 2 has been had good positioning 13 aligning bottoms of laser is located on the central point of dash receiver 12, can finish whole floors 14 sleeve pipes 15 of this mounting points or the position line that pipe clamp is installed.Each layer sleeve pipe can directly be installed as center fixation point according to laser spots.The installation of pipe clamp then needs the center line alignment with drill bit, and electric hammer is perpendicular to metope, and boring hammers into the pipe clamp card base in the wall boring again, the pipe clamp center is overlapped with laser beam get final product.

The utility model can not have the emission of generating laser wireless remote control, receiving trap and special-purpose cross laser location dash receiver yet, can be used for the location equally, and is just so not convenient.
