Description
Technical field
It the utility model is related to plant equipment manufacturing technology field, and in particular to a kind of adaptive circuit plate screw.
Background technology
Screw, also someone cry its " screw "（Screw）, " screw rod "（Lead screw）.Screw is common name in fact, and screw,
Lead screw is all mutually distinguishing.Screw is typically named wood snail in fastening wooden part, working of plastics.Lead screw is machine screw（Machinery
Screw）, be front end tack that, pitch is smaller, uniformly, is generally used for fastening metal, machine part.
Traditional circuit board with mounting hole is mostly normal screws simple in construction with screw, and lead screw is mostly cylinder knot
Structure, same specification screw can only coordinate with a screw, therefore cause the screw of thousands of kinds of different sizes, not only waste
Resource, also considerably increases production cost.
Utility model content
The utility model overcomes the shortcomings that above-mentioned, and provides a kind of adaptive circuit plate screw.
To achieve these goals, the utility model is to realize by the following technical solutions：The adaptive circuit plate
Include threaded rod, screw head, through hole, backing plate with screw and lengthen valve；The left end right angle setting backing plate of the threaded rod, backing plate
Right sidewall middle and upper part and middle and lower part one lengthening valve is installed respectively, the left side installation screw head of backing plate, screw head
Middle part sets through hole；The threaded rod, screw head, through hole, backing plate and lengthening valve are integrally formed；The longitudinal direction of the threaded rod is horizontal
Section is ellipse；The longitudinal cross-section of the screw head is rectangle；The longitudinal cross-section of the through hole is rectangle or ellipse
Shape；The longitudinal cross-section of the backing plate is rectangle；The longitudinal cross-sectional area of the backing plate is 1.3 ~ 1.6 times of screw head.
Preferably, the longitudinal cross-sectional area of the through hole is 0.5 ~ 0.7 times of longitudinal cross-sectional area of screw head.
Preferably, the longitudinal cross-sectional area of the through hole is 0.6 times of longitudinal cross-sectional area of screw head.
Preferably, the longitudinal cross-section of the through hole is rectangle.
Preferably, the longitudinal cross-sectional area of the backing plate is 1.5 times of screw head.
The beneficial effects of the utility model are：It is simple in construction, it is easy to operate, in the present invention in adaptive circuit plate screw
Backing plate and the screw for causing the screw to be adapted to all size that coordinates for lengthening valve, the scope of application are more extensive.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The implication of reference in figure, 1, threaded rod, 2, screw head, 3, through hole, 4, backing plate, 5, lengthen valve.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
With screw to achieve these goals, the utility model is to come by the following technical solutions to the adaptive circuit plate
Realize：Adaptive circuit plate screw includes threaded rod 1, screw head 2, through hole 3, backing plate 4 and lengthens valve 5；Threaded rod 1
A lengthening valve 5, a left side for backing plate 4 are installed in left end right angle setting backing plate 4, the right sidewall middle and upper part of backing plate 4 and middle and lower part respectively
Screw head 2 is installed in side, and the middle part of screw head 2 sets through hole 3；Threaded rod 1, screw head 2, through hole 3, backing plate 4 and lengthening
Valve 5 is integrally formed；The longitudinal cross-section of threaded rod 1 is ellipse；The longitudinal cross-section of screw head 2 is rectangle；Through hole 3 is indulged
It is rectangle or ellipse to cross section；The longitudinal cross-section of backing plate 4 is rectangle；The longitudinal cross-sectional area of through hole 3 is screw terminal
0.6 times of the longitudinal cross-sectional area in portion 2；The longitudinal cross-section of through hole 3 is rectangle；The longitudinal cross-sectional area of backing plate 4 is spiral shell
1.5 times of silk head 2.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
