It is directly welded on block, when block use finishes storage, ground nail is produced collision with other objects.
Then, for it is identified above the shortcomings that, we providing a kind of had contraction type ground nail and is adjusted using chute
The track and field block of two pedal unit distances, to reach the purpose for having more more practical value.
Utility model content
The purpose of this utility model is to provide a kind of track and field block, existing to solve to propose in above-mentioned background technology
Block U-lag side wall, the method for adjusting front and rear pin stampede device, using the supporting card form of neck realize that position is consolidated more
Fixed, this mode easily makes the front and rear pin stampede device after regulation that angle displacement occur, and the generation of this displacement is to training or competing
Quality is had a certain impact, and the ground nail on existing block is directly welded on block, and block use, which finishes, deposits
When putting, ground nail is easily set to produce the problem of colliding with other objects.
The purpose and effect of the utility model track and field block, are reached by technological means in detail below：
A kind of track and field block, wherein, the track and field block includes：
Main body, stampede device, slide plate, sliding block, tighten bolt, back seat, ground nail sub-assembly, tapped blind hole and chute；
The U-shaped two side of the main body offers row's tapped blind hole and a chute, and chute is located at row's screw thread
The bottom side of blind hole；The side of the stampede device is provided with sliding block；The slide plate is welded on the side of sliding block, and the end face of slide plate is passed through
Wear cooperation and be provided with and tighten bolt；The stampede device is slidably fitted on chute by sliding block；The top surface and main body of the back seat
U-lag bottom on front side of be mounted on ground nail sub-assembly.
Further, the bottom surface of the sliding block offers the strip fluting for coordinating with chute.
Further, the ground nail sub-assembly is telescopic sleeve combining structure, and back seat offers and ground nail sub-assembly
Corresponding through hole.
With existing structure in comparison, the utility model has the following advantages that：
1. the ground nail structure on original block is changed to contractile combined set formula by we from original welded type
Structure, pass through our improved this structures so that after the ground nail use on block rotating shrinking in screw shell,
It is safer when ensureing to deposit after block use, and there is good protective effect to ground nail, global design more adduction
Reason, while we will arrange groove on original block with make adjustments two stampede device distances two, be changed to chute and thread jack
Formula, stampede device recycle thread jack to realize and fixed after being adjusted by slide, by our practical tests, pass through chute
The possibility that two stampede devices slided produce angle displacement substantially reduces, than the existing side that stampede device is fixed using open flume type
Formula is more stable.
