Abstract
The invention discloses an expansion bolt which comprises an expansion sleeve (1) and a fixed bolt sleeved with the expansion sleeve. A liner plate (3) is arranged at the tail end of the expansion sleeve, and an expansion top bolt (4) for pushing the liner plate (3) to expand and fix the liner plate is arranged at the connection of the expansion sleeve and the liner plate. The liner plate is in an internal conical shape. The expansion top bolt is trapezoidal. The inner wall at the front end of the expansion sleeve is threaded. According to the expansion bolt provided by the invention, innovatively, the way of stretching outward the common expansion bolt is converted into the way of pressuring the expansion bolt inwardly, so that, on the one hand, the bolt is pulled out, and on the other hand, the expansion sleeve is prevented from being exposed out of the fixed surface. Two bolts are used to fix, so that not only is a common fixing manner realized, but also the hiding purpose is realized. If the bolt is damaged, the bolt can be replaced by common bolts.
Description
Technical field
The present invention relates to a kind of EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS is the very high fixed block of routine use frequency, but conventional EXPANSION ANCHOR BOLTS all is to adopt the bottom taper bolt outwards to stretch, expansion sleeve is expanded, so bolt all is to exceed fixed pan, for there being the fixing situation of hiding requirement to realize, if stationary plane is loose, be easy to EXPANSION ANCHOR BOLTS is pulled out, impact is fixing, and bolt is impaired can't substitute with plain bolt.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of EXPANSION ANCHOR BOLTS, this EXPANSION ANCHOR BOLTS innovation ground becomes inside press mode from the mode of the outside drawn expanded of conventional EXPANSION ANCHOR BOLTS, prevent from pulling out on the one hand bolt, prevent that on the other hand expansion sleeve from exposing stationary plane, adopt two kinds of bolts to fix, both can realize conventional means of fixation, can realize again the purpose of hiding, if bolt failure can also adopt plain bolt to substitute.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
A kind of EXPANSION ANCHOR BOLTS, the fixing bolt that comprises expansion sleeve, socket-connects with expansion sleeve; The end of described expansion sleeve is provided with liner plate, with the joint of liner plate, is provided with for promoting liner plate its expansion top of expanding fixing is fastened in expansion sleeve.
As the further optimized project of a kind of EXPANSION ANCHOR BOLTS of the present invention, described liner plate is inner conical, and fasten as trapezoidal on described expansion top.
As the further optimized project of a kind of EXPANSION ANCHOR BOLTS of the present invention, the front inner wall of described expansion sleeve is shape of threads.
As the further optimized project of a kind of EXPANSION ANCHOR BOLTS of the present invention, the outer wall of described fixing bolt is shape of threads.
As the further optimized project of a kind of EXPANSION ANCHOR BOLTS of the present invention, the outer wall of described fixing bolt front end is shape of threads.
The present invention adopts above technological scheme, compared with prior art has following technique effect:
1, this EXPANSION ANCHOR BOLTS innovation ground becomes inside press mode from the mode of the outside drawn expanded of conventional EXPANSION ANCHOR BOLTS, prevents from pulling out bolt on the one hand, prevents that on the other hand expansion sleeve from exposing stationary plane.
2, adopt two kinds of bolts to fix, both can realize conventional means of fixation, can realize again the purpose of hiding.
If 3 bolt failure can also adopt plain bolt to substitute.

Number in the figure: the 1-expansion sleeve, the 2-screw thread, 3-inner conical liner plate, 5-expansion push rod, 6-polished rod fixing bolt, 7-screw thread, 8-outside thread fixing bolt, 9-pad, 10-nut are fastened in the trapezoidal expansion of 4-top.
Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is described in further detail:
As shown in Figure 1 and Figure 2, EXPANSION ANCHOR BOLTS is by expansion sleeve 1(band internal thread 2), inner conical liner plate 3, trapezoidal expansion top fasten 4, expansion push rod 5 forms.
First get out suitable hole at stationary plane before fixing, expansion sleeve 1 is filled in the good hole of brill, then expansion push rod 5 is filled in the expansion sleeve 1, used hammer to knock the part that expansion push rod 5 exposes stationary plane, the other end of expansion push rod 5 withstands on trapezoidal expansion top and fastens on 4, promotion expansion top is fastened 4 and is moved forward, the inner conical liner plate 3 of compressing opening forces it to expand, and reaches fixing purpose, after fixing, take out expansion push rod 5.
As shown in Figure 3, if there is not special fixedly requirement, the user can be with outside thread 7 with outside thread fixing bolt 8() screw-in expansion sleeve 1, again fixed object is enclosed within on the outside thread fixing bolt 8 that (outside thread fixing bolt 8 can withstand on trapezoidal expansion top after screwing in and fasten on 4, the top that prevents from expanding is fastened 4 mobilely backward, guarantees that inner conical liner plate 3 keeps swelling states, thereby plays the anticreep effect), then put into pad 9, screw at last nut 10.Pad 9, the structure of nut 10 such as Fig. 5, shown in Figure 6.
As shown in Figure 4, if the requirement of hiding bolt is arranged, as: what hang is shelving board, and the user can be with outside thread 7 with polished rod fixing bolt 6() screw in expansion sleeve 1, again fixed object is enclosed within the polished rod part of polished rod fixing bolt 6, reach hiding purpose.
