Specific embodiment
In order to preferably state the utility model, it is further described for the utility model below in conjunction with the accompanying drawings.
Refer to Fig. 1 and Fig. 3, the fastening structure with auto-lock function of the present utility model, including with the screw thread of the first part 6
The threaded portion 1 of connection and the cylindrical portion 2 being fastenedly connected with the second part 7, threaded portion 1 and cylindrical portion 2 are formed in one structure.It is logical
The connection of threaded portion 1 and cylindrical portion 2 is crossed, the first part 6 and the second part 7 are fastenedly connected.Threaded portion 1 is provided with and the first part 6
The external screw thread 3 that installing hole internal thread matches.The upper end of cylindrical portion 2 is provided with the upper coarse and lower fine fluting 4 no less than two.
Fastening structure with auto-lock function of the present utility model, the external screw thread 3 of threaded portion 1 directly with the first part 6 in
Screw thread is threadably secured connection, and now fastening structure is fastenedly connected with the first part 6.Then cylindrical portion 2 is pressed by pressure
In entering the installing hole of the second part 7, because the upper end of cylindrical portion 2 is provided with upper coarse and lower fine fluting 4, fluting 4 is subject in installing hole
The lateral pressure of hole wall is installed, cylindrical portion 2 is pressed in installing hole and does not fall out, and can be fitted close with the second part 7, play certainly
The effect of lock.Compared with prior art, the fastening structure with auto-lock function of this case, simple structure, fastening structure is located at the
Between one part 6 and the second part 7, play a part of stealthy connect, fastening structure will not be exposed, do not interfere with the first part
6 and second part 7 it is attractive in appearance.Without the need for extraly opening up for placing conventional screw head or bolt on the second part 7
The placement space of head, reduces the processing cost of kit.
In the present embodiment, the fluting 4 no less than two is opened up along the cross-sectional uniformity of cylindrical portion 2, and no less than two
The center of fluting 4 is identical with the angle between the center of gravity of cylindrical portion 2.When fluting 4 is pressed in installing hole, the fluting being uniformly arranged
