Utility model content
In view of this, the purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of sound level meter support meanss,
Solve the technical problem that sound level meter can not rapidly adapt to different height noise measuring point, freely can quickly adjust sound level meter
Highly, it is simple in construction, it is easy to operate.
To reach above-mentioned purpose, the utility model uses following technical scheme：A kind of sound level meter support meanss, including cylinder
Body, hoisting mechanism and handle；Cylinder includes square tube and is arranged on the projection of square tube outer wall；Square tube is the hollow length of upper and lower side closing
Cube barrel structure, square tube top surface and bottom surface are equipped with string holes, and top surface sets two string holes, and bottom surface sets a string holes；
Hoisting mechanism includes spring, fixture, drawstring, link and fixed pulley system；Lower spring end is fixed on square tube bottom surface
Side, spring upper end are fixed on fixture lower surface；Fixture upper side is fixed in drawstring one end, and the other end sets link, and drawstring is another
End first passes through fixed pulley system, and then from square tube bottom surface, string holes passes, and is fixed on finally by link on projection；Number of slugs is
Several；
Fixed pulley system is arranged on the upside of square tube top surface, and fixed pulley system includes fixed pulley, bearing and wheel shaft；Wheel shaft runs through
Fixed fixed pulley, wheel shaft are installed on bearing；
Square tube horizontal cross-section is square, and the square tube wall on projection opposite sets slide rail, and short transverse of the slide rail along square tube is set,
Fixture is engaged with slide rail.
Further, projection is uniformly arranged along the short transverse of square tube.
Further, groove is set to be engaged with slide rail on fixture.
The beneficial effects of the utility model are：

Embodiment
It is specific embodiment of the utility model below, the technical solution of the utility model is further described, but
The utility model is not limited to these embodiments.
Embodiment 1
A kind of sound level meter support meanss, including cylinder, hoisting mechanism and handle 2.As shown in Figure 1-2, cylinder includes square tube 1
With the projection 12 for being arranged on square tube outer wall.Square tube 1 is the hollow cuboid barrel structure of upper and lower side closing, the top surface of square tube 1 and bottom surface
String holes is equipped with, top surface there are two string holes, and there is a string holes bottom surface, is available for drawstring 4 to pass through.
Hoisting mechanism includes spring 5, fixture 9, drawstring 4, link 13 and fixed pulley system.Sound level meter 3 is held in fixture 9
On.The lower end of spring 5 is fixed on the upside of the bottom surface of square tube 1, and the lower surface of fixture 9 is fixed in the upper end of spring 5.Folder is fixed in the one end of drawstring 4
Have 9 upper sides, the other end sets link 13, and the other end of drawstring 4 first passes through fixed pulley system, then worn from the bottom surface string holes of square tube 1
Go out, as shown in Figure 4, be fixed on finally by link 13 on projection 12.The quantity of projection 12 is several.
Fixed pulley system is arranged on the upside of the top surface of square tube 1, and fixed pulley system includes fixed pulley 6, bearing 7 and wheel shaft 8, drawstring
4 are wrapped in the top of fixed pulley 6；Wheel shaft 8 runs through fixed fixed pulley 6, and wheel shaft 8 is installed on bearing 7, and fixed pulley 6 can freely turn
It is dynamic.
As shown in figure 3, the horizontal cross-section of square tube 1 is square, the square tube wall on the opposite of projection 12 sets slide rail 10, such as the institute of accompanying drawing 2
