Abstract
An anchor expansion nut belongs to a connecting piece and mainly solves the problem of installing equipment on the ground. The anchor expansion nut comprises a columnar nut body provided with a central hole and is characterized in that an expansion sleeve coaxial with the nut body is abutted with the end of the nut body; the outer part of the expansion sleeve is cylindrical, the inner part of the expansion sleeve is provided with a conical hole, the diameter of the conical hole is same as that of the central hole of the nut body, at least two openings are arranged on the wall of the expansion sleeve in the axis direction, one end of each opening extends to the bottom end of the expansion sleeve; and a conical expansion plug arranged in the conical hole of the expansion sleeve can move axially in the conical hole under the action of an axial force. With the adoption of the anchor expansion nut, the ground equipment can be fixed conveniently, a plant environment is affected a little, and the potential safety hazard is avoided.
Description
Technical field
The present invention relates to a kind of link, particularly a kind of lower margin expanding nut.
Background technique
EXPANSION ANCHOR BOLTS is a kind of common threaded connector, is commonly used to pipeline, carriage are fixed on the wall or on the floor, perhaps machinery equipment fixed on the ground.During use, must get out first the hole of corresponding size at fixed body with electric impact drill (hammer), again in bolt, the expand tube load hole, screw nut and can make that swelling becomes one between bolt, expand tube, assembling set and the fixed body.Bolt tail has a major part, pipe slightly larger than the diameter of bolt of the outer surface cover of bolt, and the afterbody part has several roads opening, and after bolt tightening, the afterbody of major part just is brought to the pipe the inside of opening, and is large the pipe punching, reaches the purpose of expansion.
Above-mentioned stone bolt need destroy ground during installation, not only causes the workshop dust pollution, and the bottom surface needs again cure process, and cure process needs the regular hour, thereby can affect again the duration; Stone bolt partly exposes the earth's surface after female assembling simultaneously, equipment assembling docking difficulty, and easily clash into stone bolt, in case the stone bolt distortion makes the mobile device dismounting or reinstalls to become very difficult.The stone bolt potential safety hazard that also exists above ground level of exposing in addition.
Summary of the invention
The shortcoming that exists in order to overcome above-mentioned prior art the object of the present invention is to provide a kind of lower margin expanding nut, and this lower margin expanding nut stationary ground equipment is easy to use, and is little on the workshop condition impact, without potential safety hazard.
In order to address the above problem, the present invention by the following technical solutions:
A kind of lower margin expanding nut, comprise the column screw body with center hole, it is characterized in that, the end of described screw body is to being equipped with the ringfeder of coaxial inner conductor, described ringfeder outside is column, and inside is provided with tapered hole, and the Outside diameter of described tapered hole is identical with the diameter of screw body center hole, be provided with at least two openings along axial direction on the ringfeder wall, described opening one end extends to the end of ringfeder; One taper that is positioned at the ringfeder tapered hole rises by plug can be in described tapered hole axial displacement under the effect of axial force.
Described opening is four, is cross-shaped symmetrical along the ringfeder wall and distributes.
Described screw body and ringfeder are welded on one.
During use, the bottom surface pre-manufactured hole is set, rise the plug External Force Acting under in ringfeder to bottom offset, because the taper pore structure relates to, the ringfeder open part produces distortion, and the terminal oral area distortion of ringfeder is maximum, and whole lower margin expanding nut is also to bottom offset simultaneously, the lower end is close at the bottom of the hole of pre-manufactured hole, makes the lower margin expanding nut form back taper and be locked in hardened layer at hardened layer.
The invention has the beneficial effects as follows:
1: easy to process, the plug that rises after screw, ringfeder, the plug that rises can be processed is respectively put into ringfeder, then with the screw butt welding.
2: can be in enormous quantities: screw be produced in batches with thread rolling machine, but ringfeder, the plug finish forge batch production of rising.
3: not above ground level after the lower margin expanding nut assembling, tear behind the equipment lower margin expanding nut open and stay in hardened layer and not above ground level, without potential safety hazard.
4: during use, each hole can be installed one by one, be convenient to the operation adjustment.
5: face is damaged on ground few, add and do not play dirt man-hour, be beneficial to the dust-free workshop operation.
6: it is firm to use, under the plug External Force Acting that rises in ringfeder to bottom offset, simultaneously whole lower margin expanding nut is also to bottom offset, the lower end is close at the bottom of the hole of pre-manufactured hole, makes the lower margin expanding nut form back taper and be locked in hardened layer at hardened layer.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the present invention's bottom surface pre-manufactured hole structural representation when constructing;
Fig. 3 is the present invention's rear structural representation of constructing.
Among the figure: 1 screw body, 2 ringfeders, 3 plugs that rise, 4 weld seams, 5 openings, 6 pre-manufactured holes, 7 ground.
Embodiment
Shown in Figure 1, a kind of lower margin expanding nut comprises column screw body 1, establishes center hole in the screw body 1, and the end of screw body is provided with lead angle.One ringfeder, 2 inside are provided with tapered hole, the Outside diameter of described tapered hole is identical with the diameter of screw body center hole, and the ringfeder outside is column, lead angle on the top is provided with, upward form butt weld 4 between the lower lead angle of lead angle and screw body, through the one that is welded.Ringfeder 2 is identical with the shaft axis of screw body 1.
On ringfeder 2 walls, be provided with at least two openings 5 along axial direction, be preferably four, along the ringfeder wall be+font is symmetrical.Described opening one end extends to the end of ringfeder, and the other end is cecum; One taper that is positioned at the ringfeder tapered hole rises by plug 3 can be in described tapered hole axial displacement under the effect of axial force.
Screw body 1, ringfeder 2, the plug 3 that rises are processed by three parts, mainly are to enhance productivity and reduce process complexity.Three parts are processed separately, and during assembling, the plug 3 that will rise is inserted in the ringfeder 2, then ringfeder 2 and 1 welding of screw body.
Fig. 2, Fig. 3 are Construction State figure.
During construction, take suitable water drill bit 7 to bore pre-manufactured holes 6 in bottom surface, need mounting point, the aperture of pre-manufactured hole 6 is a bit larger tham the diameter of screw body 1.The present invention is inserted in the pre-manufactured hole 6, screw body 1 up, ringfeder 2 down, insert a push rod in screw body 1 and ringfeder 2 holes, the push rod overhead knocks push rod with tup on the end face of plug 3 that rises, rise the plug 3 External Force Actings under in ringfeder to bottom offset, simultaneously whole lower margin expanding nut is also to bottom offset, and the lower end is close at the bottom of the hole of pre-manufactured hole 6, makes the lower margin expanding nut form back taper and be locked in hardened layer at hardened layer.
