Description
Technical Field
The utility model relates to an electric power tool field especially relates to a prevent dismantlement structure of nut slippage screw rod nut.
Background
The key parts on large-scale projects such as bridges and large-scale machines such as automobiles need to be frequently used, the stress of the key parts has the characteristics of large load and large impact load, and the characteristics cause that nuts on the bolts are easy to loosen and even slip, thus causing accidents. If weld the nut dead on the screw rod, guaranteed that the nut can not the slippage, but when the nut need be dismantled in the maintenance, the nut dismantles inconvenient problem can appear. Therefore, the bolt in the prior art has the problem that the nut is easy to slip in the use process, and the nut is not easy to slip but is difficult to detach when being welded on the bolt.
As shown in fig. 2 to 6, a conventional nut slippage prevention bolt includes: a bolt; the bolt includes: bolt head 2 and screw 1; one end of the screw rod 1 is fixedly connected to the bolt head 2; the surface of the screw rod 1 is provided with a mounting hole 101, and the mounting hole 101 is vertical to the central axis of the screw rod 1; prevent nut slippage bolt still includes: an elastic fastener 4; the elastic clamping piece 4 comprises a clamping head 403, a guide rod 402 and an elastic mechanism 401; one end of the guide rod 402 is fixedly connected with a clamping head 403, the other end of the guide rod is fixedly connected with an elastic mechanism 401, the elastic mechanism 401 and the guide rod 402 are inserted into the mounting hole 101, and the clamping head 403 protrudes out of the surface of the screw rod 1; one end of the elastic mechanism 401 opposite to the connection position of the guide rod 402 is contacted with the bottom of the mounting hole 101, and the elastic direction of the elastic mechanism 401 points out of the mounting hole 101 from the inside of the mounting hole 101; the side of the chuck 403 facing the bolt head 2 is a surface perpendicular to the central axis of the screw rod 1, and the side opposite to the bolt head 2 is an inclined surface or a spherical surface.
The mounting hole 101 further comprises a stopper 102; the block 102 is fixedly connected to the edge of the opening, and the distance between the block 102 and the edge of the opening of the mounting hole 101 opposite to the edge is smaller than the diameter of the guide rod 402; the upper surface of the guide bar 402 is positioned in the mounting hole 101 below the stopper 102.
When the nut 3 is screwed down, the nut 3 rotates along the screw rod 1 to move towards the bolt head 2, when the nut 3 touches the inclined surface or the spherical surface of the chuck 403 opposite to the bolt head 2, the nut 3 has a downward pressure on the chuck 403, the nut 3 presses the chuck 403 into the mounting hole 101 through the inclined surface or the spherical surface, only the nut 3 needs to be rotated, the quick installation like a common nut can be realized, when the nut 3 is loosened by external force, the clamping head 403 of the elastic clamping piece 4 is exposed out of the surface of the screw rod 1, the surface of the clamping head 403 vertical to the central axis clamps the nut 3 to prevent the nut 3 from further moving towards the other end of the screw rod 1 opposite to the bolt head 2, can press dop 403 into the mounting hole 101 when nut 3 is dismantled to needs and let the back withdraw from nut 3, the utility model discloses can guarantee that nut 3 is not slipped in the use when, also can easily dismantle when dismantling. When the screw cap is used, the guide rod 402 is blocked in the mounting hole 101 below the guide rod by the block 102, so that the guide rod 402 is prevented from extending out of the surface of the screw rod 1, the screw cap 3 is blocked by the guide rod 402 when being screwed, and the safety problem caused by the elastic clamping piece 4 sliding out of the mounting hole 101 can be avoided.
However, when the nut 3 is disassembled, the elastic clamping piece 4 cannot be directly disassembled like a common nut due to blocking of the elastic clamping piece 4, the bolt can be unscrewed like a common bolt after the elastic clamping piece 4 is firstly pressed into the mounting hole 101, but the elastic clamping piece 4 is pressed into the mounting hole 101, and the problem that if the rod piece is used for pressing the elastic clamping piece 4, the rod piece can be pushed open by the nut 3 when the nut 3 is rotated, and the clamping head 403 of the elastic clamping piece 4 can be popped out of the surface of the screw rod 1 due to the fact that the upper part of the elastic clamping piece is not stressed after the rod piece is pushed open. Therefore, the spring catch 4 has a problem that it is difficult to press the mounting hole 101.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a prevent screw rod nut's of nut slippage dismantlement structure to solve above-mentioned problem.
The technical scheme of the utility model is that: a screw and nut dismounting structure for preventing a nut from slipping,
prevent screw cap slippage screw rod nut's dismantlement structure includes:
