Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the utility model.It removes
Non- otherwise indicated, all technical and scientific terms used herein has the ordinary skill with the utility model technical field
The normally understood identical meanings of personnel.
It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root
According to the illustrative embodiments of the utility model.As used herein, unless the context clearly indicates otherwise, otherwise singular
Form be also intended to include plural form, additionally, it should be understood that, when in the present specification use term "comprising" and/or
When " comprising ", existing characteristics, step, operation, device, component and/or their combination are indicated.
As shown in Figs. 1-5, a kind of to run through bolt positioning tool 10, including lower raft 1, U is provided in the lower raft 1
Type bolt notch 2,1 upper surface of lower raft are located at 2 side of U-bolt notch and are provided with openable or block U-bolt
The movable snap-gauge 3 of notch 2,1 upper surface of lower raft are additionally provided with the attachment strap 4 of projecting edge.
Here, lower raft 1 is used for and 21 clearance fit of bolt positioning groove mouth in plane in rack 20, i.e. lower raft
1 planform is substantially consistent with the planform of bolt positioning groove mouth 21 in plane in rack 20, and bolt positioning groove mouth
21 planform is roughly triangular；Attachment strap 4 has multiple, and is welded on lower raft top surface edge, attachment strap 4 when installation
21 edge of bolt positioning groove mouth is supported in fall from the bolt positioning groove mouth 21 of plane in rack 20 to prevent positioning tool 10,
It plays and the identical supporting role of attachment strap 4 at the edge that this movable snap-gauge 3 also protrudes from lower raft 1；It is placed in down through bolt 30
In U-bolt notch 2 in portion's bottom plate 1；Movable snap-gauge 3 is L-shaped, and at U-bolt notch 2, another side passes through one side bumper
Two connection bolts 5 are movably fixed to the side of U-bolt notch 2；It is U-shaped in lower raft 1 being not loaded into through bolt 30
Before bolt notch 2, the connection bolt 5a in front of movable snap-gauge 3 i.e. at U-bolt notch 2 is not installed, and movable snap-gauge 3
The connection bolt 5b at rear is loosely fixed by movable 3 opposing lower portions bottom plate of snap-gauge, 1 activity, and movable snap-gauge 3 passes through loosening at this time
Connection bolt 5b can opposing lower portions bottom plate 1 rotate by a certain angle and then open that U-bolt notch 2 is convenient to be packed into through bolt 30
In U-bolt notch 2 in lower raft 1, after being fitted into the U-bolt notch 2 in lower raft 1 through bolt 30, rotation
Turning a work dynamic snap-gauge 3 makes one side bumper at U-bolt notch 2 to prevent skidding off through bolt 30 from U-bolt notch 2, and then twists
