Abstract
The invention aims to provide a hammer installation type expansion bolt convenient to install, which comprises an expansion sleeve and a nail body, wherein the nail body is arranged in the expansion sleeve, a check sheet is arranged on a fixed end of the expansion sleeve, a fixed end of the check sheet and a sleeve wall are integrally connected, and a free end of the check sheet is arranged toward the direction of the fixed end of the expansion sleeve. The hammer installation type expansion bolt convenient to install is characterized in that a folding edge is arranged on one side of the expansion sleeve far away from the fixed end, and the thickness of the check sheet is bigger than the thickness of the sleeve wall of the expansion sleeve. When installing, a hole with a predetermined depth and a diameter is drilled on a wall by utilizing a bit firstly, then the expansion sleeve and the nail body are put into the hole, and the nail body is beaten by utilizing tools such as hammers and the like, and moves relative to the expansion sleeve. When the nail body moves, the end portion of the nail body can upwarp the free end of the check sheet to be clamped into the wall at the same time, and enables the expansion sleeve not to move relative to the wall, thereby achieving to fix the hammer installation type expansion bolt.
Description
Technical field
The invention belongs to technical field of fastening, be 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 object of the invention is to propose a kind of hammering mounting type EXPANSION ANCHOR BOLTS easy for installation.
Hammering mounting type EXPANSION ANCHOR BOLTS of the present invention 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 invention 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 the specific embodiment of the present invention 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.
