2. then, the spiral track quick door main body 60 is assembled at the installation position (the specific assembly process and principle are the assembly mode of the existing spiral track quick door main body 60, which is not improved in the present application and is not described in detail again), so that the hinge chain wheels 70 are matched and positioned in the light curtain track 90;

3. secondly, buckling a guide rail II 20 on the guide rail I10, so that a first limiting clamping protrusion II 202 is clamped in a first limiting clamping groove I1012, and a limiting clamping protrusion I1013 is clamped in a limiting clamping groove II 203, transversely positioning the guide rail II 20 to prevent the guide rail II 20 from longitudinally moving, and ensuring that a transverse overlapping surface II 201 of the guide rail II 20 is in contact with a transverse overlapping surface I1011 of the guide rail I10;

4. then, the mounting position of the self-tapping screw is positioned by the positioning groove 50 on the guide rail II 20, the self-tapping screw penetrates through the transverse overlapping surface II 201 of the guide rail II 20 and the transverse overlapping surface I1011 of the guide rail I10 and is locked and fixed in the overlapping part 101 of the guide rail I10, and therefore the mounting of the guide rail I10, the light curtain 302, the hinge wheel 70 and the guide rail II 20 is completed;

when the maintenance or the maintenance of light curtain 302 or hinge wheel 70 need to be carried out, then only need pull down self tapping screw, take off II 20 of guide rail from I10, carry out the dismantlement maintenance of light curtain 302 or hinge wheel 70 again, easy and simple to handle, effectively avoided current light curtain 302 guide rail integrated into one piece, need wholly dismantle when carrying out the maintenance of light curtain 302, lead to complex operation's problem.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
