Abstract
The invention relates to a multifunctional bolt, which comprises a bolt head, a flange, threads and a screw rod. The multifunctional bolt is characterized in that the bolt head is a hexagon shape, the tightening part of the bolt head is heightened, the flange is tightly attached to the bolt head, and at least one annular groove is formed in the screw rod and is used for mounting a clamping spring. By adopting the structure, the multifunctional bolt has the advantages that the defect of easiness in slippage in the sleeve cylinder tightening process is effectively overcome, the tightening torque is improved, the connection of the bolt is more tight and reliable, and the fetching and use of the bolt are convenient when a first fixing part and a second fixing part are fastened.
Description
Technical field
The present invention relates to a kind of Multifunctional bolt, belong to fastener areas.
Background technique
Existing bolt is constructively simple, and be mostly bolt head, screw rod and screw thread composition, but such bolt tightness when fastening object is unreliable, when articles, safety index exists hidden danger.Therefore introduce flange plate, but the face of tightening is not increased at bolt head position by common flange plate, this reduces lifting surface area, screw-down torque does not reach requirement, is very easy to skid when this just makes sleeve tighten.
Sieve is said when fastening first fixed block and the second fixed block at present on the other hand, and screw rod is first through the through hole of the first fixed block, then screw hole that is direct and the second fixed block, such operation and fetch all inconvenient, bolt is easily lost, and when again installing, causes and uses inconvenience.
Summary of the invention
The object of the invention is: a kind of operation is provided, fetches conveniently, tighten the large Multifunctional bolt conveniently tightened of position lifting surface area.
Technological scheme of the present invention is: a kind of Multifunctional bolt, comprise bolt head, flange plate, screw thread and screw rod, described bolt head is hexagon, and is increased at the position of tightening on bolt head, bolt head is close to by flange plate, and described screw rod is provided with the annular groove that at least one can install jump ring.
The quantity of described annular groove is at least two, and parallel to each other.
The ratio described bolt head being tightened the effective height in face and the nominal diameter of screw rod is 0.55-0.65.
Because affiliated screw rod is provided with annular groove, when fastening first fixed block and the second fixed block, by the through hole of the bar of bolt through the first fixed block, then Baltimore groove is blocked with jump ring, when being connected with the second fixed block again, directly by through the screw rod of the first fixed block and the screw hole of the second fixed block, operate, fetch all inconveniences; After dismounting, bolt is stuck on the first fixed block all the time, again installs and does not need to find.
The advantage that the present invention has and good effect are: effectively solve the defect of easily skidding when sleeve is tightened after adopting said structure, perfect screw-down torque, make bolt more reliably fastening when connecting, facilitate simultaneously bolt the fetching of fastening first fixed block and the second fixed block, use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Wherein 1, flange plate 2, bolt head 3, annular groove 4, screw rod
Embodiment
As shown in Figure 1, a kind of Multifunctional bolt, comprises bolt head 2, flange plate 1, screw thread and screw rod 4, described bolt head 2 is in hexagon, and increased at the position of tightening on bolt head 2, bolt head is close to by flange plate 1, described screw rod 4 is provided with at least one annular groove 3 can installing jump ring.
The quantity of described annular groove 3 is at least two, and parallel to each other.
The ratio described bolt head 2 being tightened the effective height in face and the nominal diameter of screw rod 4 is 0.55-0.65.
Because affiliated screw rod 4 is provided with annular groove 3, when fastening first fixed block and the second fixed block, by the through hole of the bar of bolt through the first fixed block, then Baltimore groove is blocked with jump ring, when being connected with the second fixed block again, directly by through the screw rod 4 of the first fixed block and the screw hole of the second fixed block, operate, fetch all inconveniences; After dismounting, bolt is stuck on the first fixed block all the time, again installs and does not need to find.
Adopt the defect effectively solving after said structure and easily skid when sleeve is tightened, perfect screw-down torque, makes bolt more reliably fastening when connecting, facilitate simultaneously bolt the fetching of fastening first fixed block and the second fixed block, use.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
Claims (3)
