Technical field
The utility model is related to mechanical spare and accessory parts technical field, and in particular to a kind of upset bolt.
Background technology
Expansion bolt is the engineering securing member commonly used in construction, and traditional expansion bolt is by bolt, tube expansion, flat
Packing ring, spring pad and nut composition.During its principle is the hole first got to expansion bolt on ground or metope, then twisted with spanner
Nut on tight expansion bolt, makes bolt walk toward outside, and the tube expansion of outside is remained stationary as, force the big first expansion set under bolt
Strut so as to which the whole hole of overflow, expansion bolt are stuck in wall, but traditional expansion bolt major part can only be used for fixed object,
It is rarely useful doing some other effects, function is too single.
Utility model content
The technical problems to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of upset bolt,
Use in providing amenities for the people, increases the security for using.
In order to solve above-mentioned technical problem, the utility model provides following technical scheme:A kind of upset bolt,
Including screw rod, expansion tube, packing ring, spring washer, nut and band ring nut, one end of the screw rod is threaded, the spiral shell
The bar other end is processed as up-small and down-big cone, and the section of the one end of the cone that described screw rod one end is processed into close to screw thread is little,
The section of the one end away from screw thread is big, and the diameter of the little head end of cone that described screw rod one end is processed into is identical with screw diameter, institute
Diameter of the diameter of the cone stub end being processed into screw rod one end slightly larger than expansion tube before unexpanded is stated, the expansion tube is set in
On screw rod, the packing ring and spring washer are successively set on screw rod on the part of expansion tube, the nut and band ring nut
Set on screw rod on threaded position.
Preferably, described expansion tube one end is provided with symmetrical expansion slits, and the expansion slits have four, described swollen
Swollen joint-cutting is distributed in cruciform symmetry.
Preferably, the expansion tube is provided with one end of expansion slits and is provided with locking teeth, and the locking teeth is four, the lock
Tight tooth is arranged on the expansion tube between two expansion slits.
Preferably, the band ring nut can also be snap-on nut and hook nut.
Preferably, the screw rod, expansion tube, packing ring, spring washer, nut and band ring nut are 304 stainless steels
Make.
The beneficial effect reached by the utility model is:The utility model can be made using the expansion tube for being provided with expansion slits
Expansion tube uniform force, compression strength are big, strengthen with the laminating degree of structural member, wear-resistant, extend the service life of expansion bolt,
Increase with ring nut design, greatly expands the use range of expansion bolt simultaneously.
