Abstract
The utility model discloses a level ruler. The level ruler comprises a ruler body, wherein at least one magnet is arranged inside the ruler body; at least one magnetic plate is arranged on the side surface of the magnet; the magnetic plate is arranged in the level ruler and comprises a magnetic end which is exposed out of the surface of the level ruler. By adoption of the level ruler disclosed by the utility model, adsorption capacity of the level ruler to a workpiece can be increased, and labor power and time waste can be effectively reduced.
Description
Technical field
The utility model relates to a kind of surveyor's staff.
Background technology
The surveyor's staff of general requirements all is a general workplace basically, also is that surveyor's staff is measured that plane of using, and places on the plane of object being measured, estimates in the measuring position.A prerequisite of Ce Lianging is exactly like this, and tested plane can provide firm support for surveyor's staff, can allow surveyor's staff work under static state.Yet a lot of operating modes and unlike hope ideal, such as measuring thing at tubulose, or measured is that two operating personnel carry out with regard to needs under the situation of end face, this has wasted time and manpower undoubtedly.By magnet is set, thereby can adsorb testee in surveyor's staff, but such design absorption affinity is insecure, surveyor's staff drops easily, still can't deal with problems.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the defective of fixing insecure consumption plenty of time of prior art surveyor's staff and manpower, a kind of surveyor's staff to be provided.
The utility model is to solve above-mentioned technical matters by following technical proposals:
A kind of surveyor's staff comprises a blade, and the inside of described blade is provided with at least one magnet, its characteristics are, the side of described magnet is provided with at least one magnetic conduction sheet, and described magnetic conduction sheet is arranged in the described surveyor's staff, and comprises the magnetic conduction end that is exposed to described surveyor's staff surface.Described magnetic conduction end can effectively be adsorbed on the measured workpiece, is not easy to come off.
Preferably, described surveyor's staff also comprises a magnetic box, the upper surface of described magnetic box comprises some magnetic conductive grooves, and the upper surface of described magnetic box is arranged in a pilot hole that is arranged on the described blade, described magnet and described magnetic conduction sheet are arranged in the described magnetic box, and the magnetic conduction end of described magnetic conduction sheet is arranged in described magnetic conductive groove.Described magnetic box has been fixed described magnet and described magnetic conduction sheet, makes that connection is more firm.
Preferably, described magnetic box comprises a pedestal and a lid that is detachably connected, and described magnetic conductive groove is arranged on the upper surface of described lid.
Preferably, the correspondence position of described pedestal and described lid is provided with threaded ends, and corresponding described threaded ends connects by screw.Connect by screw, made things convenient for the fitting operation of surveyor's staff.
Preferably, described pedestal is provided with a spring, and the upper end of described spring is connected with described magnetic conduction sheet with described magnet.The elastic force that described spring produces makes described magnetic conduction end be not easy to withdraw in the surveyor's staff.
Preferably, described pedestal is provided with a reference column, and the lower end of described spring is set on the described reference column.Reference column can be fixed described spring, avoids described spring dislocation.
Preferably, the inside of described blade is provided with two and lays bar, and described magnetic box is arranged on described laying on the bar.The described bar of laying provides stabilised platform, makes described magnetic box stablize and lays, and effectively increased the interior space availability ratio of surveyor's staff.
Preferably, described magnet is ndfeb magnet.Ndfeb magnet is the strongest permanent magnet of magnetic now, also is the magnet of normal use, is widely used in various products.
Preferably, the material of described magnetic conduction sheet is iron.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge namely gets each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: by utilization of the present utility model, can increase surveyor's staff to the adsorptive power of workpiece, effectively reduce manpower and waste of time.

Embodiment
Enumerate preferred embodiment below, and come the clearer the utility model that intactly illustrates by reference to the accompanying drawings.
As depicted in figs. 1 and 2, the surveyor's staff of present embodiment comprises a blade 1,3, two magnetic conduction sheets 4 of a magnet and spring 222.
Present embodiment also comprises a spring 222.Because the inner space of blade 1 is bigger, magnet 3 and magnetic conduction sheet 4 are not easy to fix, so be provided with a spring 222 below magnet 3 and magnetic conduction sheet 4.After spring 222 distortion, produce an elastic force, the below that elastic force acts on magnet 3 and magnetic conduction sheet 4 makes magnet 3 and magnetic conduction sheet 4 withstand blade 1, has finished fixing.
The material of magnetic conduction sheet 4 is iron, is easy to be magnetized by magnet 3.
During use, magnetic conduction end 41 is adsorbed on the measured workpiece, just can vacates hand and measure.
Embodiment 2
As shown in Figure 3 and Figure 4, the surveyor's staff of present embodiment comprises a blade 1, a lid 21, pedestal 22,3, two magnetic conduction sheets 4 of a magnet, screw 5 and spring 222.
The correspondence position of pedestal 22 and lid 21 is provided with threaded ends 211 and threaded ends 221, and corresponding described threaded ends connects by screw 5.
The upper end of spring 222 is connected with magnetic conduction sheet 4 with magnet 3.The elastic force that spring 222 produces makes magnetic conduction end 41 be not easy to withdraw in the surveyor's staff.
The inside of blade 1 is provided with two and lays bar 12, and pedestal 22 is arranged on to be laid on the bar 12.Lay bar 12 stabilised platform is provided, make pedestal 22 stablize and lay, and effectively increased the interior space availability ratio of surveyor's staff.
The material of magnetic conduction sheet 4 is iron, is easy to be magnetized by magnet 3.
During use, magnetic conduction end 41 is adsorbed on the measured workpiece, just can vacates hand and measure.
Though more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
