Abstract
The utility model discloses a kind of gradient meter based on lead, is related to teaching aid, and the utility model includes tablet and protractor, and equipped with shaft, which is inserted on the side of tablet at the places 1cm above the midpoint of protractor bottom edge；Protractor bottom edge midpoint is connected to connecting rod, and lead is connected on the other end of connecting rod；The side that tablet installs protractor is equipped with reference to item, parallel with the bottom edge of tablet with reference to item；When being parallel to horizontal plane with reference to item, the zero graduation line of protractor is overlapped with reference to item；When needing to measure the gradient of some plane, pedestal is put on this plane, protractor is under the tenesmus effect of lead, the zero graduation line of protractor still maintains parallel with horizontal plane, which but overlapped at this time with angle line of protractor with reference to item, then the angle that the gradient of this plane is indicated for this protractor angle line.
Description
Technical field
The utility model is related to teaching aids, and in particular to a kind of gradient meter based on lead.
Background technology
It is the angle measurement work that the indispensability such as line, construction, installation, decoration, finishing, management, quality supervision, examination is tested in project planning
Tool, is mainly used in the measurement of flatness, levelness, verticality, the gradient.Compared to traditional " seeing that bubble moves, discernable by eye "
Measurement method, the measurement method of electronic horizontal ruler " detection of electrons, number display " is more accurate and intuitively.And the current gradient
The cost of meter is higher and using complexity, is unsuitable to apply in teaching.
Utility model content
The utility model aim is to solve the above problems, and the utility model provides a kind of gradient meter based on lead,
Its is simple in structure, of low cost, is suitable for teaching and uses.
The purpose of this utility model is achieved through the following technical solutions：
A kind of gradient meter based on lead, including two tablet, protractor same connecting rods, protractor bottom edge midpoint
Shaft is equipped at the 1cm of top, which is inserted on the side of tablet；The both ends on the protractor bottom edge respectively with a connecting rod one
End is fixed, and the other end of two connecting rods is interconnected and fixed, this, which is connected and fixed on a little, is additionally provided with lead, the lead and protractor
The line at bottom edge midpoint is parallel to plumb line always；The side of the tablet installation protractor, which is equipped with, refers to item, the reference
Item is parallel with the bottom edge of tablet；When being parallel to horizontal plane with reference to item, the zero graduation line of the protractor is overlapped with reference to item.
Further, the tablet bottom edge is equipped with chassis, and the lower surface of the chassis is parallel with reference to item, and chassis makes this
Utility model can be more stably placed in plane in use.
By using the utility model, following advantageous effect can be generated：The utility model includes tablet and protractor, amount
Shaft is equipped with above the midpoint of angle device bottom edge at 1cm, which is inserted on the side of tablet；Protractor bottom edge midpoint is connected to connecting rod,
It is connected to lead on the other end of connecting rod；The side that tablet installs protractor is equipped with reference to item, flat with reference to the bottom edge of item and tablet
Row；When being parallel to horizontal plane with reference to item, the zero graduation line of protractor is overlapped with reference to item；When the slope for needing to measure some plane
When spending, pedestal is put on this plane, protractor is under the tenesmus effect of lead, and the zero graduation line of protractor still maintains and water
Plane is parallel, but is overlapped at this time with which angle line of protractor with reference to item, then the gradient of this plane is this protractor angle
The angle that line is indicated.
Description of the drawings
Attached drawing described herein is used for providing further understanding the utility model embodiment, constitutes the one of the application
Part does not constitute the restriction to the utility model embodiment.In the accompanying drawings：
Fig. 1 is the stereoscopic schematic diagram of the utility model.
Label and corresponding parts title in attached drawing：1- tablets, 2- protractors, 3- refer to item, 4- connecting rods, 5- leads,
6- chassis.
Specific implementation mode
To make the purpose of this utility model, technical solution and advantage be more clearly understood, with reference to embodiment and attached drawing,
The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this
Utility model is not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of gradient meter based on lead, including tablet 1, the same connecting rod 4 of protractor 2 two, it is described
Shaft is equipped with above 2 bottom edge midpoint of protractor at 1cm, which is inserted on the side of tablet 1；The two of 2 bottom edge of the protractor
One end respectively with a connecting rod 4 is held to fix, the other end of two connecting rods 4 is interconnected and fixed, this is connected and fixed on a little and is additionally provided with
The line of lead 5,2 bottom edge midpoint of the lead 5 and protractor is parallel to plumb line always；The tablet 1 installs protractor 2
Side, which is equipped with, refers to item 3, described parallel with the bottom edge of tablet 1 with reference to item 3；When being parallel to horizontal plane with reference to item 3, the amount
The zero graduation line of angle device 2 is overlapped with reference to item 3；1 bottom edge of tablet is equipped with chassis 6, the lower surface of the chassis 6 and with reference to item 3
It is parallel.
Above-described specific implementation mode, to the purpose of this utility model, technical solution and advantageous effect carried out into
One step is described in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
It changes, improve, should be included within the scope of protection of this utility model.
