Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Fig. 1 is the side-looking structural representation of a preferred embodiment of hand tighten screw assembly of the present utility model; Fig. 2 is the sectional structure schematic representation when not connecting of a preferred embodiment of the linkage structure of application hand tighten screw assembly of the present utility model; Sectional structure schematic representation when Fig. 3 is the connection of a preferred embodiment of linkage structure of application hand tighten screw assembly of the present utility model (among the figure for structure show clear, and not shown label).
Figure 1 shows that a preferred embodiment of hand tighten screw assembly of the present utility model, as shown in Figure 1, the comprising of the utility model hand tighten screw assembly: hand tighten screw spare A, rivet spare B.
Wherein, hand tighten screw spare A comprises head 1 and bar portion 2.Head is used for hand contact with hand when twisting, and therefore as preferably, head 1 has rolled straight burr, so that make things convenient for hand stubborn stressed.Bar portion 2 comprises thread section 2a and smooth section 2b, and as shown in fig. 1, the radial dimension of smooth section 2b forms the step surface of an annular less than the radial dimension of thread section 2a between them; Thread section 2a is provided with outside thread.The center of rivet spare B is provided with inconsistent tapped hole 4 in aperture and smooth hole 5, they are concentric hole, just their axis overlaps, wherein tapped hole 4 is provided with internal thread, and its aperture is less than the aperture of smooth hole 5, so form the step surface of annular between tapped hole 4 and the smooth hole 5, the side that rivet spare B is positioned at above-mentioned smooth hole 5 is provided with riveted structure 3.
Shown in Figure 2 is a preferred implementation using the linkage structure of hand tighten screw assembly shown in Figure 1, and as shown in Figure 2, the linkage structure of application hand tighten screw assembly of the present utility model is except also comprising: upper cover plate 6, lower cover plate 7.Wherein upper cover plate 6 is provided with the hole 8 of sprouting, and can match with the outside thread of the thread section of above-mentioned hand tighten screw spare A in this hole 8 of sprouting.Lower cover plate 7 and rivet spare B riveted joint, rivet spare B passes lower cover plate 7 and is riveted on the lower cover plate 7 by riveted structure 3.
With reference to Fig. 2 and Fig. 3, when connecting, hand tighten screw spare A is from a side shown in Fig. 2, thereby pass upper cover plate 6 by the precession hole 8 of sprouting, after waiting to pass, that sprout hole 8 correspondences is smooth section 2b, because the radial dimension of smooth section 2b is less than thread section 2a, and the size in the hole 8 of sprouting is the size that is slightly less than thread section 2a, because upper cover plate 6 has certain plasticity, in precession, can pass, so in case after thread section 2a screws out, remove unartificial position of specially adjusting hand tighten screw spare A, outside oppositely screwing out, by the size of smooth section 2b less than the hole 8 of sprouting, so under the state of freely placing, hand tighten screw spare A is in the state of inclination all the time, the step surface between smooth section 2b and the thread section 2a guarantees that hand tighten screw spare A and upper cover plate 6 do not break away from.
In the time upper cover plate 6 and lower cover plate 7 will being linked together, as long as the tapped hole 4 that the thread section 2b of hand tighten screw spare A is aimed at rivet spare B screws and upper cover plate 6 constituted with lower cover plate 7 fixedly connected, smooth hole 5 is used to hold the remaining part of hole 8 and hand tighten screw spare A bar portion 2 of sprouting.When needing dismounting, the head of hand rotation hand tighten screw spare A screws out tapped hole 4 with thread section 2b, can separate upper cover plate 6 and lower cover plate 7, and hand tighten screw spare A and upper cover plate 6 can not break away from again simultaneously, convenient assembling once more.Such linkage structure is applicable to the tabular assembly that needs frequent dismounting.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technological scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the present utility model.
