Abstract
The utility model relates to the technical field of connecting pieces, in particular to a combined bolt. The combined bolt comprises a first threaded rod with external threads, a first nut fixed to one end of the first threaded rod, a second threaded rod with external threads and a second nut fixedly arranged at one end of the second threaded rod. A threaded hole is formed in the middle of the first nut in the axis direction and the second threaded rod can be inserted into the threaded hole to be matched with the threaded hole in a threaded mode. In the use process, a sheet material can be fixed through matching of the first threaded rod and the first nut, another sheet material can be fixed by inserting the second threaded rod into the first threaded rod and through matching between the second threaded rod and the second nut, and a plurality bolts can be arranged in the same way so as to realize fixing of a plurality of sheet materials. In follow-up disassembling, connection of other sheet materials cannot be affected when a prior sheet material is disassembled.
Description
Technical field
The utility model relates to link technical field, is specifically related to a kind of combined bolt.
Background technique
Existing plain bolt is only the nut of screw rod, one, and this spline structure can not meet the use of specific occasion, while linking together as multi-layered board is superposeed, just need to adopt very long bolt, and during dismounting, after bolt is pulled down, all sheet material just can become flexible.
Model utility content
For above-mentioned technical problem, the utility model provides a kind of combined bolt simple in structure, easy to use.
Realize the technical solution of the utility model as follows:
Combined bolt, comprise and there is externally threaded the first screw rod, be fixed on first nut of first screw rod one end, there is externally threaded the second screw rod, and the second nut that is fixedly installed on second screw rod one end, at the first nut middle part axial direction, offer screw, above-mentioned the second screw rod can insert in screw and its screw-thread fit.
Described screw extends to 1/3 place of the first screw rod.
The external diameter of described the second screw rod is the 1/4-1/3 of the first screw rod external diameter.
Described the second nut middle part axial direction offers the through hole that extends to the second screw rod end face.
Described through hole is circular port, and it is the 1/6-1/5 of the second screw rod external diameter.
Adopted such scheme, in use, by being fixed a sheet material the first screw rod and coordinating of the first nut, and by the second screw rod, insert in the first screw rod and with coordinating of the second nut and can another sheet material be fixed again, the like, a plurality of bolts can be set, realization is fixing to a plurality of sheet materials, in dismounting afterwards, during the upper sheet material of dismounting, can not have influence on the connection of other sheet materials.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Referring to Fig. 1, combined bolt, comprise and there is externally threaded the first screw rod 1, be fixed on first nut 2 of first screw rod one end, there is externally threaded the second screw rod 3, and the second nut 4 that is fixedly installed on second screw rod one end, at the first nut middle part axial direction, offering screw 5, above-mentioned the second screw rod 4 can insert in screw and its screw-thread fit.In concrete enforcement, screw 5 extends to 1/3 place of the first screw rod.The external diameter of the second screw rod is the 1/4-1/3 of the first screw rod external diameter.At the second nut middle part axial direction, offer the through hole 6 that extends to the second screw rod end face, can carry out antirustly to adding Lubricants in through hole, through hole be circular port, and it is the 1/6-1/5 of the second screw rod external diameter.
