Abstract
The utility model relates to an expansion bolt, in particular to an internally-fastening demounting type expansion bolt, which resolves the problem that an existing expansion bolt is single in function and inconvenient to demount. The internally-fastening demounting type expansion bolt comprises an internal thread sleeve, wherein a plurality of groove holes parallel to the axis of the internal thread sleeve are arranged on a column face of the inner end of the internal thread sleeve, an expansion lead screw with the tail portion in a conical shape and the head portion in an inner hexagonal or outer hexagonal shape is screwed in the internal thread sleeve, and a fixing lead screw is screwed at the outer end of the internal thread sleeve. The expansion bolt is reasonable and reliable in structural design, wide in function and purpose and capable of replacing all existing expansion bolts. Simultaneously, the expansion bolt can achieve free demounting, resolves inconvenience caused by not enabling to be pulled out, can be used repeatedly and has no effect on anchoring surface. The expansion bolt is convenient and quick to install and can simultaneously be installed on multiple vertical faces, thereby improving work efficiency by more than twice.
Description
Technical field
The utility model relates to EXPANSION ANCHOR BOLTS, is specially a kind of interior tightening and loosening formula EXPANSION ANCHOR BOLTS.
Background technique
Along with making constant progress of society in recent years, the continuous innovation of technology, the application of EXPANSION ANCHOR BOLTS are ripe gradually; The purposes of fixed object is only played in the effect of existing common EXPANSION ANCHOR BOLTS, and the form of screw rod or nut can not change, and purposes is more single; The scope of using is comparatively limited to, and satisfies for the application in various fields is very difficult, and is not quick detachable after installing simultaneously; Be unfavorable for the saving of cost, the consumption reduction of the energy, the practicality for society need, the theory of multipotency do not appear in embodiment.
Summary of the invention
The utility model provides a kind of interior tightening and loosening formula EXPANSION ANCHOR BOLTS in order to solve existing EXPANSION ANCHOR BOLTS function singleness and not easily detachable problem.
The utility model is to adopt following technological scheme to realize: interior tightening and loosening formula EXPANSION ANCHOR BOLTS; Comprise the internal thread sleeve pipe; The inner cylinder of internal thread sleeve pipe has some and slotted eye its parallel axes; And it is that cone structure, head are the bloated screw mandrel of interior hexagonal or outer-hexagonal that internal thread sleeve pipe the inner is screwed with afterbody, and internal thread sleeve pipe outer end is screwed with fixedly screw mandrel.During use, the screw mandrel that expands is screwed in the inner of internal thread sleeve pipe, is placed on then in the body of wall of pore-forming; Stretch in the internal thread sleeve pipe from the outside with spanner then, interior hexagonal through the screw mandrel head that expands or the outer-hexagonal screw mandrel that will expand is tightened, thus with internal thread sleeve pipe tensioner in body of wall; At this moment fixedly screw mandrel is screwed in internal thread sleeve pipe outer end; The anchoring filament club head is replaceable to be any screw thread products such as suspension ring, pipe clamp head or radiator hook, thereby realizes its multiple use, dismantles convenient reliable simultaneously.
The utility model reasonable in design is reliable, and the function multipurpose is wide, and instead has various EXPANSION ANCHOR BOLTSs now; Simultaneously can realize freely dismantling, solve and pulled out to come out the inconvenience that brings in the past, can also reuse, can not influence anchoring face; Quick and easy for installation, can carry out the fastening installation of many facades simultaneously, more than the twice before work efficiency can improve.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of internal thread sleeve pipe among Fig. 1.
Among the figure: 1-internal thread sleeve pipe, 2-slotted eye, the 3-screw mandrel that expands, 4-is screw mandrel fixedly.
Embodiment
Interior tightening and loosening formula EXPANSION ANCHOR BOLTS; Comprise internal thread sleeve pipe 1; The inner cylinder of internal thread sleeve pipe 1 has some and slotted eye 2 its parallel axes; And it is that cone structure, head are the bloated screw mandrel 3 of interior hexagonal or outer-hexagonal that internal thread sleeve pipe 1 the inner is screwed with afterbody, and internal thread sleeve pipe 1 outer end is screwed with fixedly screw mandrel 4.In the practical implementation process, it is too much that the diameter of perforating must not surpass the diameter of bolt, not firm to prevent anchoring.
