The purpose of the present invention is cancelling pressure-riveting process connection, using the technique that is spirally connected, first existStainless steel lock two installation
M6 thread is attacked at end, and doing a step surface prevents hexagon nut with flange installation rear catch from having shaking and the risk that falls off, finally lock
Button is bent into U-shaped, and specific size is according to lower Fig. 3 bending, and away from being L, lock height is H1 at bending center；Put into lock stiffening plate two
It installs in threaded hole, and selects band two M6 loading end nuts of anti-skid teeth urgent, as shown in figure 4, spiro connecting piece is selected (to be spirally connected
The stud section of part is hexagon flange bolt) it is urgent across front hatch cover lock body assembly and preceding housing assembly.
Relative to the riveted structure of the prior art as shown in Figure 1, lock 5, which installs threaded hole installation end with stiffening plate 4, is
Pressure-riveting process, because stiffening plate is aluminium sheet, lock is stainless steel material, has shaking after the softer the two riveting of stiffening plate substrate and falls off
Risk, hair lid have shaking phenomenon when lock sticks into latch hook when closed.
The application provides a kind of front hatch cover metal plate lock and reinforces plate assembly structure, as shown in figures 2 and 5, including lock 5 with
The stiffening plate 4 of front hatch cover；The interlude of stiffening plate is set there are two connecting hole, and lock 5 is equipped with installation threaded hole；It latches 5 and adds
Strong plate 4 is connected using spiro connecting piece；Spiro connecting piece includes the stud 1 of U-shaped structure, and the both ends of stud are equipped with bolted joint 3；Spiro connecting piece
Stud through installation threaded hole, to realize fixed lock, two bolted joints are one-to-one to run through two connecting holes, and by nut lock
It is fixed；The diameter of stud is greater than the diameter of connecting hole, and the diameter of connecting hole is greater than the diameter of bolted joint.
The spiro connecting piece that the application uses is equipped with step 2, step surface and nut the cooperation locking lock of step on bolted joint
With front hatch cover, the outer diameter of step is twice or twice or more of bolted joint diameter；Wherein, the outer diameter of step is the two of stud outer diameter
Times；Nut is hexagon nut with flange, in order to guarantee the stability of locking, the anti-skidding rotating gripper of installation loading end band of nut.Spiral shell
The end of connector is equipped with chamfering.The length of bolted joint is 3 times or more of connecting hole thickness.
Preferably, spiro connecting piece is process using following steps: selection stainless steel column, processing stainless steel column both ends are spirally connected
Head respectively revolves one step surface of riveting at bolted joint, then carries out bending processing from middle section to stainless steel column.
As in Figure 2-4, specific embodiment:
