Wherein: 1- mine car link block；2- rectangular channel；3- loop chain；4- thread groove；5- strip groove；6- bolt；7- limited block；
8- mounting base；9- back box；10- magnet.
Specific embodiment
As shown in Figure 1, the utility model discloses a kind of anti-drop devices of mine car bolt, comprising: mine car link block 1, square
Shape slot 2, loop chain 3, thread groove 4, strip groove 5, bolt 6, limited block 7, mounting base 8, back box 9, magnet 10, the mine car link block
Rectangular channel 2 is provided with inside 1, the iron hoop of 3 end of loop chain protrudes into rectangular channel 2, and the thread groove 4 is provided in rectangular channel 2
On the mine car link block 1 of side, the strip groove 5 is provided on the outside of mine car link block 1 relative to thread groove 4, the thread groove 4,
Strip groove 5 is connected with rectangular channel 2, the bolt 6 pass inwardly through strip groove 5,3 end of loop chain iron hoop after with 4 spiral shell of thread groove
Line connection, the affixed limited block 7 in 6 outer end of bolt, the mounting base 8 is fixed in 1 outer end face of mine car link block, and installs
Seat 8 is placed in 5 left side of strip groove, and the end face of the back box 9 towards 1 side of mine car link block is respectively arranged on the left side and the right side the side turned up
Edge, 9 left end of back box are transferred by pin shaft and mounting base 8, and the magnet 10 is fixed in the jink on 5 right side of strip groove
At 1 outer peripheral surface, the back box 9 is made of iron material, and can rotate counterclockwise around the pin shaft in mounting base 8 and wrap limited block 7
It covers.
Plane where the rectangular channel 2 and plane locating for 1 inner face of mine car link block are parallel each other.
The thread groove 4 extends internally from rectangular channel 2 but not through entire mine car link block 1.
The strip groove 5 runs through entire mine car link block 1 from rectangular channel 2 outward.
6 inner end of bolt is equipped with the external screw thread to match with thread groove 4.
The utility model is implemented: mine car link block 1 is installed on the outer end face of U-shaped mine car, when use first
The iron hoop of 3 end of loop chain is placed in rectangular channel 2, then bolt 6 is inserted into strip groove 5, bolt 6 passes through iron hoop and and screw thread
