Detailed description of the invention
For the benefit of the understanding to the present invention, illustrates below in conjunction with drawings and Examples.
Referring to Fig. 1 to Fig. 4, the present invention provides a kind of nut mounting device, and it can be used for upper and lower of life line system
Organize the installation exercise of connected nut between frame, but concrete application is not limited to this, such as has other between nut and lower carriage
Can rotate in order to draw nut that to be tightened against the installing mechanism of bolt the most applicable.
Specifically, nut mounting device of the present invention mainly includes the lower bracket 10 being provided with bolt 30 and by nut 40
It is installed on the upper bracket 20 of described lower bracket 10.Wherein:
As it is shown on figure 3, described lower bracket 10 has a pedestal 11, described pedestal 11 has an end face 12, described bolt
30 are convexly equipped on described end face 12.In the present embodiment, the main body that described pedestal 11 has an inverted T shape combine that both sides tiltedly set
Support part institute constitutor；More specifically, described pedestal 11 and bolt 30 can be the objects being bonded by two components, it is also possible to
It it is the overall object formed by welding or other combination technology means commonly used in the art.
As shown in Figure 1 and Figure 2, described upper bracket 20 has a base 21, and described base 21 has relative end face 211
And bottom surface 212, described end face 211 is provided with connecting rod 22 and is connect with a guide 24 groups by spacer pin 23；And described base 21
End face 211 is arranged with corresponding described nut 40 shape and a nut groove 25 for size, and described nut groove 25 bottom land is provided with a through hole
26, described through hole 26 connects the bottom surface 212 of described nut groove 25 and described base 21, in order to place described bolt 30, thus relatively
Good for circular port, but be not limited to this, it is as the criterion so that described bolt 30 can be placed smoothly.
In the present embodiment, the pedestal 11 of the corresponding described lower bracket 10 of base 21 of described upper bracket 20 is installed, and
Base 21 bottom surface 212 of described upper bracket 20 is pasted after fastening nut 40 with pedestal 11 end face 12 of described lower bracket 10
Close.
In the present embodiment, described base 21 is provided with two connecting rods 22, and described guide 24 is the component being configured to π shape,
There are transverse tube 241 and two montants 242；Described transverse tube 241 inner hollow is provided with a through wires hole 243, in order to place life line 27；
Described two montants 242 of described guide 24 connect with two connecting rods 22 on described base 21, and are worn by described spacer pin 23
Put described two montants 242 and connecting rod 22, make guide 24 be connected on connecting rod 22；Therefore nut mounting device of the present invention is in institute
Stating after guide 24 wears and strain life line and obtain location, make upper bracket 20 to be rotated further by, tool is prevented effectively from top and props up
Frame 20 rotates the Advantageous Effects unscrewing nut 40.
As shown in Figure 3, Figure 4, described bolt 30 is convexly equipped on pedestal 11 end face 12 of described lower bracket 10, in order to place
Described through hole 26, and pass described nut groove 25 after described nut 40 is installed.
As shown in Figure 2, Figure 3, Figure 4, described nut 40 is configured to hexagon, is similarly hexagonal in order to accommodating being fixed on
In nut groove 25, and rotarily driven by described upper bracket 20 thus to be tightened against described bolt 30 outside.
The concrete structure of nut mounting device of the present invention described above, below please compound conjunction and refer to Fig. 3, Fig. 4, this is described
The installation method of bright nut mounting device.
First described bolt 30 is placed through hole 26 and the nut groove 25 of described upper bracket 20, makes bolt 30 top be positioned at
Between two connecting rods 22 of described upper bracket 20；Nut 40 is inserted between described two connecting rods 22 by now, and is manually screwed into bolt
30 tops；When bolt 30 is tentatively twisted in bolt 30 behind location, mention described upper bracket 20, make nut 40 alignment insert nut
In groove 25, making the lower half of nut 40 be placed in described nut groove 25, the first half is exposed to outside nut groove 25, whereby, due to
Nut 40 has identical non-circular structure with nut groove 25 and size is suitable so that nut 40 can the most securely be housed
In nut groove 25, and will not dally in nut groove 25；Finally, described spiral shell can be driven by the described upper bracket 20 of rotation
Female 40 rotate, so that nut 40 is screwed into described bolt 30 easily, and in base 21 bottom surface 212 of upper bracket 20 with dynamic
After fitting with pedestal 11 end face 12 of lower bracket 10, make nut 40 and upper bracket 20 be tightened and be installed on lower bracket 10
On.
Further, the present invention is mounted on the base 21 of described upper bracket 20 by being directed to part 24；At nut
After 40 are tightened against described bolt 30, the life line 27 of life line bearing 100 is placed described guide 24, when straining described life
After line 27, the transverse tube 241 of described guide 24 is i.e. located in same orientation, and then traction makes described base 21 fixing no longer
Rotate.
According to upper, the present invention passes through aforementioned nut erecting device and installation method thereof, by the end in described upper bracket 20
The methods that seat 21 arranges nut groove 25, really and effectively improve small space and cannot use the tired of instrument fastening nut 40
Difficulty, self is fabricated to a nut screwing tool by the upper bracket 20 of life line bearing, except ensureing each of life line bearing
The function of ingredient, has more accelerating construction progress, saves manpower simultaneously and reduces the danger of steel house surface construction
Deng Advantageous Effects.
Being described in detail the present invention above in association with drawings and Examples, those skilled in the art can basis
