Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, a kind of bolt with locking functions, including nut 1 and screw rod 2, the inner wall of screw rod 2 is socketed
There is a protective jacket 16, protective jacket 16 is disposed with the first water accepting layer 17,18 and second water accepting layer 19 of rubber layer from the inside to surface, and first
17 and second water accepting layer 19 of water accepting layer is that absorbing resin material is made, and rubber layer 18 is made of rubber material, is inhaled by first
Water layer 17, rubber layer 18 and second water accepting layer 19 are used cooperatively, and be can be very good to carry out waterproof to the bolt, are improved the spiral shell
The water resistance of bolt, is provided with the first push rod 3 at the center at the top of nut 1, and the two of 1 top of both sides and nut of the first push rod 3
Side has been fixedly connected with the second magnet 21, and the first push rod 3 is flexibly connected by the second magnet 21 with nut 1, the first push rod 3
One end passes through nut 1 and extends to the inside of screw rod 2, and the bottom of the first push rod 3 is fixedly connected with extrusion ball 4, the first push rod 3
Front be provided with sliding rail 5, the front of sliding rail 5 slidably connects sliding block 6, and the top of sliding block 6 is fixedly connected with the second push rod 7,
One end of second push rod 7 and the front of the first push rod 3 have been fixedly connected with the first magnet 20, and the second push rod 7 passes through the first magnetic
Iron 20 is flexibly connected with the first push rod 3, and the both sides of sliding block 6 are connected with linking arm 8, and one end of linking arm 8, which is fixed, to be connected
The first nail tip 9 is connected to, the outer surface of screw rod 2 offers first through hole 10, and the first nail tip 9 passes through screw rod 2 and extends to outside it
Portion, can be very square by being used cooperatively for sliding rail 5, sliding block 6, the second push rod 7, linking arm 8, the first nail tip 9 and first through hole 10
Linking arm 8 is moved in first through hole 10 just, and linking arm 8 is expressed to it is parallel with first through hole 10, it is achieved thereby that
Secondary fixation of first nail tip 9 to the bolt improves the anti-loosening property of the bolt again, and the bottom of screw rod 2 is fixedly connected with
Punch 11, the inner wall of punch 11 are fixedly connected with supporting rod 12, and the quantity of supporting rod 12 is four, and two supporting rods 12 are one
Group, one end of supporting rod 12 are fixedly connected with elastic piece 13, and the side of elastic piece 13 is fixedly connected with the second nail tip 14, linking arm
8 and second the angle of nail tip 14 and horizontal position be 30 degree, the outer surface of punch 11 offers the second through-hole 15, and the second nail
Point 14 passes through punch 11 and extends to outside it, is followed closely by the first push rod 3, extrusion ball 4, supporting rod 12, elastic piece 13, second
Being used cooperatively for 14 and second through-hole 15 of point, can very easily squeeze elastic piece 13 using extrusion ball 4, in elasticity
Second nail tip 14 is extruded out from the second through-hole 15 under the active force of piece 13, facilitates the second nail tip 14 and the bolt is carried out
It is fixed, improve the anti-loosening property of the bolt.
When in use, the first push rod 3 is pushed down on first, and the first push rod 3 pushes extrusion ball 4 to move downward, then squeezes
Ball 4 squeezes elastic piece 13, and under the action of elastic piece 13, the second nail tip 14, which is extruded out, consolidates the bolt
It is fixed, then sliding block 6 is pushed to be moved in sliding rail 5 by the second push rod 7, linking arm 8 is pushed into first under the action of sliding block 6
In through-hole 10, then continue to push sliding block 6, linking arm 8 starts to rotate, when linking arm 8 turns to horizontal position, stops pushing away
The secondary fixation to the bolt can be completed in movable slider 6 at this time.
In conclusion the first push rod 3, extrusion ball 4, supporting rod 12, elastic piece should be passed through with the bolt of locking functions
13rd, the second nail tip 14 and the second through-hole 15 are used cooperatively, and very easily elastic piece 13 can be squeezed using extrusion ball 4
Pressure, second nail tip 14 is extruded out from the second through-hole 15 under the active force of elastic piece 13, and it is right to facilitate the second nail tip 14
The bolt is fixed, and improves the anti-loosening property of the bolt, passes through sliding rail 5, sliding block 6, the second push rod 7, linking arm 8, first
Linking arm 8, can very easily be moved in first through hole 10 by being used cooperatively for nail tip 9 and first through hole 10, and will connection
Arm 8 be expressed to it is parallel with first through hole 10, it is achieved thereby that secondary fixation of first nail tip 9 to the bolt, improves this again
The anti-loosening property of bolt.
