Preferably, described first reinforcing bar 3 and the second reinforcing bar 12 are rigid rod.
Preferably, the length that bar 12 reinforced by described first reinforcing bar 3 with second is equal.
Further, the second end of described 3rd universal joint 4 distance away from bearing pin 7 end face is equal with first wing plate 6 upper end distance away from bearing pin 7 end face；The second end of described 4th universal joint 10 distance away from bearing pin 7 end face is equal with second wing plate 6 upper end distance away from bearing pin 7 end face.
The beneficial effects of the utility model are:
When using safety pin of the present utility model, being first inserted in the collar by bearing pin, the mode that is then threaded connection by baffle plate is connected with the end face of bearing pin；Baffle plate plays barrier effect, in case shotpin axle comes off, and the therefore diameter being directly greater than the collar of baffle plate.After baffle plate is fixed, by the first Fixing shrink ring on the first wing plate, and by the second Fixing shrink ring on the second wing plate.Owing to the second end of the 3rd universal joint distance away from bearing pin end face is equal with the first wing plate upper end distance away from bearing pin end face；The second end of the described 4th universal joint distance away from bearing pin end face is equal with the second wing plate upper end distance away from bearing pin end face；The connection of the first retainer ring and the first wing plate, and the connection of the second retainer ring and the second wing plate plays and prevents out of stock function further.
The utility model simple in construction, low cost, easy to use, and it is possible to prevent out of stock.
Accompanying drawing explanation
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model mine safety pin.
Detailed description of the invention
Embodiment 1
A kind of mine safety pin, including bearing pin 7, bearing pin 7 end face is provided with thread groove 11, and baffle plate 1 is arranged below the screw rod 14 threadeded with thread groove 11.
Baffle plate 1 has been arranged with the first universal joint 2 and the second universal joint 13 further below；The first end of the first universal joint 2 is connected with baffle plate 1, the second end of the first universal joint 2 and first is reinforced the first end of bar 3 and is connected, the first end of the first the second end reinforcing bar 3 and the 3rd universal joint 4 connects, and the second end of the 3rd universal joint 4 connects the first retainer ring 5；The first end of the second universal joint 13 is connected with baffle plate 1, the second end of the second universal joint 13 and second is reinforced the first end of bar 12 and is connected, the first end of the second the second end reinforcing bar 12 and the 4th universal joint 10 connects, and the second end of the 4th universal joint 10 connects the second retainer ring 9.First reinforcing bar 3 and the second reinforcing bar 12 are rigid rod, and the first reinforcing bar 3 is equal with the length of the second reinforcing bar 12.
The first wing plate 6 and the second wing plate 8 it is fixedly installed on bearing pin 7；First retainer ring 5 is connected with the first wing plate 6, and the second retainer ring 9 is connected with the second wing plate 8.The shape of the first wing plate 6 and the second wing plate 8 closely cooperates with first collar 5, second collar 9 respectively；After first collar 5 is enclosed within the first wing plate 6, can the first universal joint 2 and the 3rd universal joint 4 be stretched, after second collar 9 is enclosed within the second wing plate 8, the second universal joint 13 and the 4th universal joint 10 stretch；So may further ensure that baffle plate 1, without departing from bearing pin, plays and prevents out of stock effect.
The second end of the 3rd universal joint 4 distance away from bearing pin 7 end face is equal with first wing plate 6 upper end distance away from bearing pin 7 end face；The second end of the 4th universal joint 10 distance away from bearing pin 7 end face is equal with second wing plate 6 upper end distance away from bearing pin 7 end face.
When using safety pin of the present utility model, being first inserted in the collar by bearing pin, the mode that is then threaded connection by baffle plate is connected with the end face of bearing pin；Baffle plate plays barrier effect, in case shotpin axle comes off, and the therefore diameter being directly greater than the collar of baffle plate.After baffle plate is fixed, by the first Fixing shrink ring on the first wing plate, and by the second Fixing shrink ring on the second wing plate.Owing to the second end of the 3rd universal joint distance away from bearing pin end face is equal with the first wing plate upper end distance away from bearing pin end face；The second end of the 4th universal joint distance away from bearing pin end face is equal with the second wing plate upper end distance away from bearing pin end face；The connection of the first retainer ring and the first wing plate, and the connection of the second retainer ring and the second wing plate plays and prevents out of stock function further.
