Abstract
The present invention relates to a kind of upset bolt, including key and be sheathed on the bolt sleeve outside key, key front end is fixedly connected with a tension piece can opened outside key both sides, bolt sleeve front end is coniform, during locking, bolt sleeve front end is resisted against tension piece, forces tension piece to be flared out, described bolt sleeve perisporium is provided with through hole, is provided with the stud that can outwards sting out between described key and bolt sleeve.Present configuration is simple, this configuration avoids existing expansion bolt easily to occur to skid to rotate and this defect that causes getting loose in the installation of existing composite light brick wall, by the bolt end with tension piece, the bolt sleeve utilizing taper in implementation process forces tension piece to open to prevent bolt from skidding, the stud that can outwards sting out, further ensures the anticreep of expansion bolt.
Description
Technical field
The present invention relates to a kind of upset bolt.
Background technology
Expansion bolt, be pipeline is propped up/hangs/bracket or equipment is fixing on the wall, on floor, a kind of special thread connector used on post.But the existing wall brick used that builds a building is essentially light-duty composite shaped block material, as first-class in foamed bricks, hollow brick, the installation carrying out expansion bolt on such metope easily occurs to skid and cause bolt can to rotate in brick, even falls off and causes the accident.
Summary of the invention
Rotate and this defect that causes getting loose to overcome existing expansion bolt easily to occur to skid in the installation of existing composite light brick wall, the present invention designs a kind of upset bolt, this expansion bolt includes key and is sheathed on the bolt sleeve outside key, described key front end is fixedly connected with a tension piece can opened outside key both sides, described bolt sleeve front end is coniform, during locking, bolt sleeve front end is resisted against tension piece, tension piece is forced to be flared out, described bolt sleeve perisporium is provided with through hole, is provided with the stud that can outwards sting out between described key and bolt sleeve.
Further, described tension piece has multiple, and the plurality of tension piece is around being formed in up-small and down-big umbrella.
Further, described key circumferentially portion is provided with helical groove, and described groove gradually becomes shallower as along the depth of groove of key direction of rotation, and described stud inner end is embedded in groove, and when bolt sleeve rotates, stud stings out from bolt sleeve.
Further, on rear side of described key, it is provided with external screw thread, is provided with the locking nut that can match with external screw thread on rear side of bolt sleeve, between locking nut and bolt sleeve, is provided with packing ring.
Compared with prior art, the method have the advantages that present configuration is simple, this configuration avoids existing expansion bolt easily to occur to skid to rotate and this defect that causes getting loose in the installation of existing composite light brick wall, by the bolt end with tension piece, the bolt sleeve utilizing taper in implementation process forces tension piece to open to prevent bolt from skidding, the stud that can outwards sting out, further ensures the anticreep of expansion bolt.

Detailed description of the invention
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
As shown in Fig. 1～2, the present invention designs a kind of upset bolt, this expansion bolt includes key 10 and is sheathed on the bolt sleeve 20 outside key, and described key 10 front end is fixedly connected with a tension piece 30 can opened outside key both sides, and described bolt sleeve 20 front end is coniform, tension piece 30 has multiple, multiple tension pieces 30 are around being formed in up-small and down-big umbrella, and during locking, bolt sleeve 20 front end is resisted against tension piece 30, tension piece 30 is forced to be flared out, to prevent bolt from deviating from.
Bolt sleeve 20 perisporium is provided with through hole 210, is provided with the stud 40 that can outwards sting out between described key 10 and bolt sleeve 20.
Key 10 circumferentially portion is provided with helical groove 110, and described groove 110 gradually becomes shallower as along the depth of groove of key 10 direction of rotation, and stud 40 inner end is embedded in groove, and when key 10 rotates, stud 40 stings out from bolt sleeve 20.Under the common effect of stud 40 and tension piece 30, it is ensured that the anti-skidding anticreep of bolt sleeve.
It is provided with external screw thread on rear side of key 10, is provided with the locking nut 50 that can match with external screw thread on rear side of bolt sleeve, between locking nut and bolt sleeve, is provided with packing ring.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent and modification, all should belong to the covering scope of the present invention.
