Abstract
The invention relates to a novel expansion bolt. The novel expansion bolt comprises a bolt body and a bolt sleeve arranged outside the bolt body in a sleeved mode, wherein a tension piece capable of expanding outwards to the two sides of the bolt body is fixedly connected to the front end of the bolt body, and the front end of the bolt sleeve is conical. When the expansion bolt is locked, the front end of the bolt sleeve abuts against the tension piece so that the tension piece can be forced to expand outwards. Through holes are formed in the peripheral wall of the bolt sleeve, and a protruding nail capable of protruding outwards in a piercing mode is arranged between the bolt body and the bolt sleeve. The novel expansion bolt is simple in structure, the defect that when an existing expansion bolt is installed in an existing light composite brick wall, the existing expansion bolt can slide and rotate easily, and consequently the expansion bolt loosens is overcome; due to the bolt end with the tension piece, the tension piece is forced to expand through the conical bolt sleeve in the implementation process so that the bolt can be prevented from sliding; anti-disengaging of the expansion bolt is further guaranteed due to the protruding nail capable of protruding outwards in the piercing mode.
Description
Technical field
The present invention relates to a kind of upset bolt.
Background technique
eXPANSION ANCHOR BOLTS, be pipeline is propped up/hangs/bracket or equipment are fixing on the wall, a kind of special thread link used on floor, on post.But the existing wall brick adopting that builds a building is light-duty composite shaped block material substantially, as first-class in foamed bricks, hollow brick, the installation of carrying out EXPANSION ANCHOR BOLTS on such metope is easily skidded and causes bolt in brick, to rotate, and even comes off and causes the accident.
Summary of the invention
Easily skid and rotate and this defect that causes getting loose in the installation of existing composite light brick wall in order to overcome existing EXPANSION ANCHOR BOLTS, the present invention designs a kind of upset bolt, this EXPANSION ANCHOR BOLTS comprises key and is sheathed on the bolt sleeve of key outside, described key front end is fixedly connected with the tension piece that can open outside key both sides, described bolt sleeve front end is coniform, when locking, bolt sleeve front end is resisted against tension piece, force tension piece outwards to open, described bolt sleeve perisporium is provided with through hole, is provided with the protruding nail that can outwards sting out between described key and bolt sleeve.
Further, described tension piece has multiple, and described multiple tension pieces are up-small and down-big umbrella around formation.
Further, described key is provided with helical groove along peripheral part, and described groove shoals gradually along the depth of groove of key sense of rotation, and described protruding nail inner end is embedded in groove, and in the time that bolt sleeve rotates, protruding nail stings out from bolt sleeve.
Further, described key rear side is provided with outside thread, and bolt sleeve rear side is provided with the locking nut that can match with outside thread, between locking nut and bolt sleeve, is provided with packing ring.
Compared with prior art, the present invention has following beneficial effect: the present invention is simple in structure, this structure has avoided existing EXPANSION ANCHOR BOLTS easily to skid and rotate and this defect that causes getting loose in the installation of existing composite light brick wall, by the bolt end with tension piece, in implementation process, utilize the bolt sleeve of taper to force tension piece to open to prevent that bolt from skidding, the protruding nail that can outwards sting out, has further ensured the anticreep of EXPANSION ANCHOR BOLTS.

Fig. 3 is the protruding pin structure schematic diagram of the present invention.
Fig. 4 is bolt arrangement generalized section of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Fig. 1～2, the present invention designs a kind of upset bolt, this EXPANSION ANCHOR BOLTS comprises key 10 and is sheathed on the bolt sleeve 20 of key outside, and described key 10 front ends are fixedly connected with the tension piece 30 that can open outside key both sides, and described bolt sleeve 20 front ends are coniform, tension piece 30 has multiple, multiple tension pieces 30 are up-small and down-big umbrella around formation, and when locking, bolt sleeve 20 front ends are resisted against tension piece 30, force tension piece 30 outwards to open, to prevent that bolt from deviating from.
Bolt sleeve 20 perisporiums are provided with through hole 210, are provided with the protruding nail 40 that can outwards sting out between described key 10 and bolt sleeve 20.
Key 10 is provided with helical groove 110 along peripheral part, and described groove 110 shoals gradually along the depth of groove of key 10 sense of rotation, and protruding nail 40 inner ends are embedded in groove, and in the time that key 10 rotates, protruding nail 40 stings out from bolt sleeve 20.Under the acting in conjunction of protruding nail 40 and tension piece 30, ensure the anti-skidding anticreep of bolt sleeve.
Key 10 rear sides are provided with outside thread, and bolt sleeve rear side is provided with the locking nut 50 that can match with outside thread, between locking nut and bolt sleeve, is provided with packing ring.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
