Abstract
The utility model provides a simple to operate's hammering installation formula expansion bolts. The utility model discloses a hammering installation formula expansion bolts includes the expansion sleeve and the nail body, the nail body is installed in expansion sleeve, expansion sleeve's stiff end is equipped with the non return piece, the stiff end of non return piece and a section of thick bamboo wall body coupling, the free end of non return piece is towards expansion sleeve's stiff end orientation, one side that its characterized in that expansion sleeve kept away from the stiff end is equipped with the hem, the thickness of non return piece is greater than expansion sleeve's section of thick bamboo the thickness of the wall. In when installation, at first utilize the drill bit to drill out the hole of desired depth and diameter on the wall, then put into expansion sleeve with the nail body should be downthehole, utilize instrument such as hammer to strike the nail body, make that it personally experiences sth. Part of the body to follow closely removes for expansion sleeve. When the nail body moved, the tip of the nail body will be with the free end perk of non return piece and block into the wall, make expansion sleeve more relative wall move, realized fixed to hammering installation formula expansion bolts.
Description
Technical field
The utility model belongs to technical field of fastening, is related specifically to a kind of EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS in general be expansible anchor of metal, its fixation principle is as follows: EXPANSION ANCHOR BOLTS utilize wedge shape gradient to impel expand produce friction bond stress, reach fixed effect.One, bolt is screw thread, and one has tapering.Outer bread one iron sheet cylinder, there are some otch one end of iron sheet cylinder, they are filled in hole that wall is accomplished fluently together, then split nut, nut pulls outward bolt, tapering is drawn in iron sheet cylinder, and the incision of iron sheet cylinder is by spreading, so tightly fixing on the wall, be generally used for fastening on the material such as cement, brick such as protective grating, rain cover, air-conditioning.
Above-mentioned EXPANSION ANCHOR BOLTS needs to utilize bolts and nuts to coordinate when mounted, and it is convenient not to install.
Summary of the invention
The purpose of this utility model proposes a kind of hammering mounting type EXPANSION ANCHOR BOLTS easy for installation.
Hammering mounting type EXPANSION ANCHOR BOLTS of the present utility model comprises expansion sleeve and rivet nut, described rivet nut is installed in expansion sleeve, the fixed end of described expansion sleeve is provided with non-return sheet, and the fixed end of described non-return sheet is connected with barrel one, and the free end of non-return sheet is towards the fixed end direction of expansion sleeve; It is characterized in that expansion sleeve is provided with flanging away from the side of fixed end; The thickness of described non-return sheet is greater than the thickness of the barrel of expansion sleeve.
When mounted, first (diameter in this hole should equal or slightly larger than the diameter of expansion sleeve to utilize drill bit on wall, get out the hole of predetermined depth and diameter, the degree of depth in this hole should slightly larger than the length of expansion sleeve), then expansion sleeve and rivet nut are put into this hole, utilize the instruments such as hammer to knock rivet nut, rivet nut is moved relative to expansion sleeve.While rivet nut movement, the free end of non-return sheet will tilt and snap in wall by the end of rivet nut, expansion sleeve cannot be moved by opposing sides again, achieve fixing hammering mounting type EXPANSION ANCHOR BOLTS.Above-mentioned flanging can be used for fixing other parts, directly bears pulling force, instead of utilizes rivet nut to bear pulling force, deviates from the possibility of expansion sleeve because this reducing rivet nut.
Further, the thickness of described non-return sheet is increased to free end gradually by fixed end, and less power can be utilized like this to knock in rivet nut to sleeve depths.
Further, described expansion sleeve is the cylinder structure that sheet material is rolled into, and described non-return sheet is arranged on expansion sleeve with impact style, to reduce costs.
Further, the end of described rivet nut is taper, so that rivet nut is mobile to body of wall inside.
Hammering mounting type EXPANSION ANCHOR BOLTS of the present utility model instead of the mode of rotating bolt when mounted by the mode of knocking rivet nut, therefore install very convenient, fixed effect strengthens greatly.
Accompanying drawing explanation
Fig. 1 is the structure sectional view (non-installment state) of the hammering mounting type EXPANSION ANCHOR BOLTS of embodiment 1.
Fig. 2 is the structure sectional view (installment state) of the hammering mounting type EXPANSION ANCHOR BOLTS of embodiment 1.
Accompanying drawing indicates: 1, expansion sleeve; 2, non-return sheet; 3, rivet nut; 4, flanging.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and working principle etc. of embodiment of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the hammering mounting type EXPANSION ANCHOR BOLTS of the present embodiment comprises expansion sleeve 1 and rivet nut 3, described rivet nut 3 is installed in expansion sleeve 1, the fixed end of described expansion sleeve 1 is provided with non-return sheet 2, the fixed end of described non-return sheet 2 is connected with the barrel one of expansion sleeve 1, and the free end of non-return sheet 2 is towards the fixed end direction of expansion sleeve 1; It is characterized in that expansion sleeve 1 is provided with flanging 4 away from the side of fixed end; The thickness of described non-return sheet 2 is greater than the thickness of the barrel of expansion sleeve 1, and the thickness of non-return sheet 2 is increased to free end gradually by fixed end, and less power can be utilized like this to knock in rivet nut 3 to sleeve depths.
Further, the cylinder structure that described expansion sleeve 1 is rolled into for sheet material, described non-return sheet 2 is arranged on expansion sleeve 1, to reduce costs with impact style.
Further, the end of described rivet nut 3 is taper, so that rivet nut 3 is mobile to body of wall inside.
As shown in Figure 2, when mounted, first (diameter in this hole should equal or slightly larger than the diameter of expansion sleeve 1 to utilize drill bit on wall, get out the hole of predetermined depth and diameter, the degree of depth in this hole should slightly larger than the length of expansion sleeve 1), then expansion sleeve 1 and rivet nut 3 are put into this hole, utilize the instruments such as hammer to knock rivet nut 3, rivet nut 3 is moved relative to expansion sleeve 1.While rivet nut 3 movement, the free end of non-return sheet 2 will tilt and snap in wall by the end of rivet nut 3, expansion sleeve 1 cannot be moved by opposing sides again, achieve fixing hammering mounting type EXPANSION ANCHOR BOLTS.Above-mentioned flanging 4 can be used for fixing other parts, directly bears pulling force, instead of utilizes rivet nut 3 to bear pulling force, deviates from the possibility of expansion sleeve 1 because this reducing rivet nut 3.
