Fig. 2 is a lateral plan of existing captive screw mounting structure application；
Fig. 3 is the captive screw mounting structure of the utility model embodiment.
Wherein reference numeral is：1,11- captive screw, 2,22- nut is installed, 3,33- mounting plates, the first major arcs of 221-
Hole, 222- rectangular openings, the second major arcs of 223- hole.
Specific implementation mode
It elaborates to the utility model below in conjunction with attached drawing.
As shown in figure 3, the captive screw mounting structure of the utility model adjustable type, including captive screw 11 and installation
The bar portion of nut 22, captive screw 11 includes light bar segment and thread segment, and wherein light bar segment is set close to 11 head of captive screw
It sets, thread segment is arranged in the tail portion of captive screw 11, and the shape of installation nut 22 is identical as internal via shape.Nut 22 is installed
Endoporus is slotted hole, and slotted hole is by rectangular opening 222 and positioned at the first major arc hole 221 and the second major arc hole 223 at rectangular opening both ends
Composition.2/3 circle screw thread is provided in first major arc hole 221, the second major arc hole 223 is unthreaded hole or threaded hole, when the second major arc hole
For unthreaded hole when, rectangular opening is exactly to enable captive screw in rectangular opening and the second major arc together with the second major arc hole role
It is finely tuned up and down in hole；When being threaded in the second major arc hole, the second major arc hole is identical with the effect in the first major arc hole, when
When carrying out screw installation using the first major arc hole, rectangular opening and the second major arc hole captive screw can be enable in rectangular opening and
It is finely tuned up and down in second major arc hole；When carrying out screw installation using the second major arc hole, rectangular opening and the first major arc hole energy
Captive screw is enough set to be finely tuned up and down in rectangular opening and the second major arc hole；The width of rectangular opening is more than screw body
Partial diameter is less than major arc hole internal thread major diameter.
When carrying out module installation using the utility model, installation nut 22 is riveted on captive screw on mounting plate 33
Installation place, captive screw 11 screw in riveting installation nut 22, and the installation threaded hole on cabinet need to be with the circular arc of installation nut 22
Hole size corresponds to；Screw pass through riveting installation nut 22 thread segment after, at this time if there is on cabinet installation threaded hole with
The center of captive screw 11 on module mounting plate 33 is not at same center, the diameter of light bar segment in captive screw 11
