Background technology
Connection between various general honeycomb bread board class large-sized sheet material and sub-truss is all that singe screw connects or singe screw is connected with nut combinations usually, shortcoming one: honeycomb bread board class large-sized sheet material can not separate with the connection between sub-truss and adjusts, when producing dislocation up and down, not easily leveling connects, and locking stability is good not.Shortcoming two: the corrosion resistant plate used due to honeycomb bread board class surface is all thin plate, single thread connects singe screw and nut combinations and in the middle of using, produces stress concentrate and cannot discharge stress, and the degree of balance regulates difficult thus can make the locally drawing crack damage of bread board corrosion resistant plate.
Summary of the invention
The invention provides a kind of special pair of screw thread coupling, object is to improve connection reliability between honeycomb bread board class large-sized sheet material and sub-truss, the light leveling of honeycomb bread board, and whole mechanism stable is reliable, be convenient to regulate, and not easily drawing crack honeycomb bread board surface stainless sheet steel.
Technical solution of the present invention is as follows:
A kind of special pair of screw thread coupling, its feature is that its formation comprises center connecting screw rod, has internal thread and externally threaded two-flight screw cover, upper spheric washer, tool female two-flight screw cover outer nut, lower peripheral surface packing ring and locking nut;
Described center connecting screw rod is one two sections of externally threaded stepped cylindrical screw rods, and one section is path external screw thread, and another section is large footpath external screw thread; This path external screw thread is threaded with the thin corrosion resistant plate of upper connected piece honeycomb bread board through after described upper spheric washer, this large footpath external screw thread is connected with the internal thread that described two-flight screw overlaps, and large footpath external screw thread afterbody is connected with the internal thread of locking nut through described lower peripheral surface packing ring;
The external screw thread of described two-flight screw cover is threaded with lower connected piece sub-truss, described two-flight screw cover outer nut is enclosed within outside two-flight screw cover, when two-flight screw cover to be connected with connected piece sub-truss put in place after two-flight screw overlapped outer nut lock at connected piece sub-truss lower bottom part place and two-flight screw external threading.
The externally threaded upper face of path of described center connecting screw rod is provided with centrally axisymmetric small arc-shaped groove, and being used for increases the pliability of this center connecting screw rod when being connected with upper connected piece honeycomb bread board, improves and regulates comfort level.
The screw socket upper surface of described two-flight screw cover is provided with inside rounding arc angle, for placing upper spheric washer, and adjustment use, thus make whole connector reliable and stable in the middle of use.
Described externally threaded external diameter end, large footpath has milled out a bit of square post, is convenient to adjustable wrench and installs adjustment.
Adjustment process of the present invention and effect: use large section of the square Zhu Shi center connecting screw rod of active handle center of rotation connecting screw rod afterbody to screw in the screwed hole matched in two-flight screw cover, allow small end external screw thread on the connecting screw rod of center mate through internal thread hole on the surperficial thin corrosion resistant plate of large spheric washer and honeycomb bread board be connected, utilize the end face conical surface contact Automatic Levelling that the land portions of spheric washer and two-flight screw overlap, when honeycomb bread board is levelling be in place after, the two-flight screw cover outer nut that two-flight screw puts is twisted to bread board direction, two-flight screw is overlapped lock with sub-truss.The locking nut of locking belt small sphere of exterior rearview packing ring, makes to lock between center connecting screw rod and honeycomb bread board, can realize locking with the independence of sub-truss and honeycomb bread board, and overall structure locking is reliable and stable.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, but should not limit the scope of the invention successively.
Refer to Fig. 1, Fig. 2, as seen from the figure, a kind of special pair of screw thread coupling of the present invention, comprises center connecting screw rod 1, two-flight screw cover 2, upper spheric washer 3, two-flight screw cover outer nut 4, lower peripheral surface packing ring 5, locking nut 6.Described center connecting screw rod 1 is one two sections of externally threaded stepped cylindrical screw rods, comprises one section of path external screw thread M1 and a section of large footpath external screw thread M2.Its path external screw thread M1 is threaded with the thin corrosion resistant plate of upper connected piece honeycomb bread board S1 through after upper spheric washer 3, its large footpath external screw thread M2 is connected with the internal thread M3 that two-flight screw overlaps 2, external screw thread M2 afterbody is connected with locking nut 6 internal thread through lower peripheral surface packing ring 5, is convenient to have regulated rear center's connecting screw rod 1 and two-flight screw to overlap locking between 2.There are two groups of symmetrical small arc-shaped groove C1 at the screw rod place at path external screw thread M1 place, being used for increasing the pliability of this center connecting screw rod 1 when being connected with upper connected piece honeycomb bread board S1, improving and regulating comfort level.Large external screw thread M2 external diameter end, footpath mills out a bit of square post F1 simultaneously, is convenient to adjustable wrench and installs adjustment.
Described two-flight screw cover 2, comprise one section of internal thread M3 and external screw thread M4, its internal thread M3 coordinates with the external screw thread M2 of center connecting screw rod 2, external screw thread M4 is threaded with the carrying out of lower connected piece sub-truss X1, simultaneously external screw thread M4 is connected with the internal thread that two-flight screw overlaps outer nut 4, when two-flight screw overlap 2 to be connected with lower connected piece sub-truss X1 put in place after two-flight screw overlapped outer nut 4 overlap 2 screw-threaded couplings at connected piece sub-truss X1 lower bottom part place and two-flight screw.Two-flight screw overlaps the 2 inside rounding arc angles in screw socket upper surface, for placing upper spheric washer 3 adjustment use, thus makes whole mechanism reliable and stable in the middle of use.
Show through on probation, the present invention utilizes the internal and external threads in structure independently to regulate to guarantee honeycomb bread board and so on being connected between large-sized sheet material with sub-truss to produce when dislocation is connected and can effectively leveling connection locking put in place, spheric washer guarantees that honeycomb bread board can easily leveling, locking nut improves this connector mechanism reliable lock and overall structure stability, integrated model balance is easy to adjust, Stability Analysis of Structures, connects reliable lock.
