It is clamped between bolt 5 and nut, inserted terminal is pressed on convex ribs 12 to realize.
The cross section of the inserted terminal of connector 3 is convex shape, is provided in one end of the close convex ribs 12 of inserted terminal to two
The ontology of the boss 33 of interval projection between convex ribs 12, boss 33 and inserted terminal forms convex shape structure.Inserted terminal it is convex
Platform 33 is embedded between two convex ribs 12, reduces the thickness of inserted terminal.And connector 3 has the inclined-plane 34 arranged in opposite directions, inclined-plane
34 be along the direction close to the side of connector holding tank 15 towards the side of close fastener holding tank 16, towards aluminium alloy
The inner inclination setting of profile.Two inclined-planes 34 of connector 3 have been cooperatively formed along close to the side of connector holding tank 15
Towards the direction of the side close to fastener holding tank 16, the two sides of convex ribs 12 are to be in the shape of the letter V arrangement to form bore gradually
The throat structure of contraction.
When technical staff assembles the body frame in the utility model, the column 2 and crossbeam 1 of body frame will be first formed
It is placed on corresponding position, then two inserted terminals of connector 3 is respectively corresponded to the connector for being embedded into column 2 or crossbeam 1 again
In holding tank 15, the convex ribs 12 of 15 bottom of connector holding tank are enable to be supported inserted terminal, and adjust on inserted terminal
Perforation 32 is corresponding with the interior coupling part 6 in fastener holding tank 16, and bolt 5 is enable smoothly to penetrate.Interior coupling part 6 is spiral shell
It is female to screw cooperation with bolt 5, inserted terminal can be pressed on convex ribs 12, realize connector 3 and column 2 or crossbeam 1 and fix
Connection is then to realize to fix by connector 3 between column 2 and crossbeam 1.
Fluted 31 are arranged on the inserted terminal of connector 3, the depth of groove 31 is not less than the thickness on the head of bolt 5,
The head of bolt 5 can be made to submerge in groove 31, and the inserted terminal of connector 3 is embedded in holding tank, technology people
Interior trim 4 can be directly anchored on the surface of column 2 or crossbeam 1 by member, not have protrusion on the outer surface of column 2 or crossbeam 1
Structure will not play interference to the installation of interior trim 4, can be improved the aesthetics of body frame.
In order to guarantee the reliability being spirally connected, when bolt 5 and interior coupling part 6 are spirally connected, locking place can be carried out
Reason, smears locking glue, or locking glue, Lai Shixian bolt 5 are smeared in the screw hole of interior coupling part 6 on the screw thread of bolt 5
It is locking with interior coupling part 6.
In other embodiments, bolt is also provided in fastener holding tank, the head of bolt is embedded into fastening
In part holding tank, the bar portion of bolt is extend into connector holding tank out of fastener holding tank, is cooperated with nut.
In other embodiments, fastener holding tank and connector holding tank can also pass through other shapes in aluminium alloy extrusions
Formula is formed, such as the width by being integrally formed the fastener holding tank and connector holding tank that are formed is inconsistent, and fastener holds
It receives the narrower width of slot, can satisfy the head of inserted num or bolt.
In other embodiments, the boss on connector can also be not provided with gradient, and be arranged to flat face, accordingly
Inclined-plane is no longer set on the convex ribs of aluminium alloy extrusions, and is arranged to flat face, the interval between two convex ribs is not less than boss
Width.
In other embodiments, there are no more groove, the head of bolt or nuts can protrude connector on connector
Surface the depth of connector holding tank is increased, head or the nut of bolt are enable in order to guarantee the flatness of body frame
Enough it is embedded into connector holding tank, and no longer protrudes the upper surface of connector holding tank.
