Description
【Technical field】
The present invention relates to the technical field of nut, especially a kind of anti-technical field for pulling rivet nut.
【Background technology】
With the development of automotive light weight technology technology, by using aluminum alloy materials and more nonmetallic zero on vehicle body
Lightweight may be implemented in part, reaches better energy-saving and environment-friendly effect to mitigate body quality.Currently, car body of aluminum alloy is big
The structure of aluminium alloy extrusions skeleton combination covering, the wherein connection type of aluminium alloy extrusions is all used predominantly to weld and rivet.
Have simple for process for the opposite welding of riveting, equipment, frock clamp are at low cost, and vehicle body is not susceptible to deformation etc. in assembly
Therefore feature realizes that the connection of aluminium alloy extrusions, application are also increasingly extensive by way of riveting.
Rivet nut is to realize that staking connects by hand riveter, it is suitable for image space pipe, pipe etc. and is not easy to be pressed
The occasion of riveting operation.Rivet nut does not need tapping thread when applying, and need not weld, can one using pneumatically or manually hand riveter
Secondary rivet clasp, convenient, fast, existing riveting nut can influence to connect in use there is a phenomenon where nut and plank skidding
Firmness.In addition, if stroke tunes too large when hand riveter draws aluminum nut or air pressure tune get Tai Gao is easy to pull screw thread.
【Invention content】
The purpose of the present invention is exactly to solve the problems of the prior art, proposes that one kind is anti-and pulls rivet nut, can pass through
Diameter is set in the first Nut column and first increases the second through-hole reduced again from top to bottom so that the first Nut column is when by staking
Drum is to bulging position control first from most weak spot, cuts ring by first, second cuts ring and slitting is cut into be fixed
Plate surface to prevent plate to be fixed from skidding, by increase the second nut column bottom wall thickness and separation nut and hand riveter and
The fixed internal thread of bolt prevents nut thread from being pulled to enhance pull-off force and shearing force of the nut when by staking.
To achieve the above object, the present invention propose it is a kind of anti-pull rivet nut, including screw head, the first Nut column and the
The upper and lower ends of two Nut columns, first Nut column are connected with screw head and the second Nut column respectively, second nut
The side upper end of column is connected with first and cuts ring, and described first cuts and be connected with second on ring and cut ring, if the bottom surface of the screw head is equipped with
Dry item slitting, the screw head are internally provided with first through hole, and first Nut column is internally provided with the second through-hole, and described second
Nut column is internally provided with third through-hole and fourth hole, the first through hole, the second through-hole, third through-hole and fourth hole phase
The inner wall of connection, the first through hole, third through-hole and fourth hole is equipped with internal thread.
Preferably, described first cuts ring and second and cut ring and be gradually reduced from bottom to end thickness, described second cuts ring
The end end of cutting ring higher than first.
Preferably, the section of the slitting is triangular in shape, the slitting is gradually reduced from top to bottom thickness.
Preferably, the bottom surface of the screw head is additionally provided with coarse lines.
Preferably, the first through hole is identical with the diameter of third through-hole, the diameter of second through-hole is from top to bottom
First increase and reduce again, the diameter at second through-hole both ends with first through hole and third through-hole diameter, the fourth hole
Diameter is less than the diameter of third through-hole.
Preferably, the diameter of first Nut column is less than the diameter of the second Nut column.
One or more of ring is cut preferably, can also be arranged in addition to described first cuts ring and second cuts ring.
Beneficial effects of the present invention：The present invention first increases reduce again from top to bottom by the way that diameter is arranged in the first Nut column
The second through-hole so that the first Nut column when by staking first from most weak spot drum to control bulging position, pass through
First cuts ring, second cuts ring and slitting is cut into plate surface to be fixed to prevent plate to be fixed from skidding, by increasing the second spiral shell
The wall thickness and separation nut of female column bottom and hand riveter and the fixed internal thread of bolt are to enhance nut when by staking
Pull-off force and shearing force prevent nut thread from being pulled.
The feature and advantage of the present invention will be described in detail by embodiment combination attached drawing.
