Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is that the self-locking anchor head of easy expanding of the utility model expands the positive view before valve opens;
Fig. 2 be Fig. 1 in A-A to part-structure sectional view;
Fig. 3 is that the self-locking anchor head of easy expanding of the utility model expands the positive view after valve opens.
Specific embodiment
Below in conjunction with the utility model embodiment, the technical solution in the utility model embodiment is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of embodiment of the utility model, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work
Under the premise of every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 to 3, the self-locking anchor head of easy expanding of the utility model comprising anchor pole 1, casing 2, several expansions
Valve 3 and steel wire 4.
The anchor pole 1, including sequentially connected straight pipe 11, glissile segment 12, reducer 13 and latter end 14 from top to bottom.
Wherein, straight pipe 11, casing 2 are nested in 11 outside of straight pipe, and guiding sleeve 2 moves downward.
Glissile segment 12, when expansion valve 3 does not open, expansion valve 3 is attached to 12 outside of glissile segment, reduces integral diameter, side
Just it protrudes into drilling.11 diameter of straight pipe is greater than glissile segment 12, in this way, the step between straight pipe 11 and glissile segment 12 can rise
To position-limiting action, prevent expansion valve 3 from deviating from.
Reducer 13, guidance expansion valve 3 are gradually opened and are fixed.Upper part diameter is identical as glissile segment 12, lower diameter
It becomes larger, in this way, during expansion valve 3 gradually glides, the branch of banding effect and 13 surface of reducer by steel wire 4
Support effect, gradually opens.Fluted 10 are arranged on reducer 13, on the other side, expansion 3 surface of valve is correspondingly arranged on protrusion
30, limit is realized in the two cooperation.Specifically, groove 10 is disposed in proximity to 13 intersection of glissile segment 12 and reducer, protrusion 30 is set
It is disposed adjacent to expansion 3 top position of valve.In this way, be caught in groove 10 in the limited situation of 4 deformation of steel wire convenient for protrusion 30,
Steel wire 4 is prevented to be broken.Further, it is caught in groove 10 for the ease of protrusion 30, the groove 10 is square groove, and protrusion 30 is
Flat column protrusion.Specifically, the groove 10 is annular groove.Specifically, expansion 3 bottom inside of valve is provided with rounded corner.It avoids
Expansion valve 3 is withstood by groove 10, and inhibition cannot push down.
Specifically, expansion 3 length of valve is greater than the length of 13 inclined surface of reducer, expand the radius after opening, anchoring effect
Fruit is more preferable.
14 diameter of latter end is less than or equal to 13 lower diameter of reducer.
Several expansion valves 3 are attached to 1 outside of anchor pole and are symmetrical arranged with 1 center axis rotation of anchor pole, and 4 banding of steel wire is respectively expanded
Valve 3, casing 2 is nested in 1 outside of anchor pole and bottom alignment respectively expands 3 top of valve.Specifically, being opened for the ease of expansion valve 3, expand
Opening is arc surface at the top of valve 3, in this way, expansion valve 3 using protrusion 30 and 10 contact position of groove as dot, expands opposite set at the top of valve 3
2 bottom surface of pipe rotation, so that expansion 3 bottom of valve be opened.Specifically, expansion 3 surface of valve is provided with embedded groove 31, embedded groove 31 with
Protrusion 30 is respectively arranged at expansion 3 two sides of valve and in sustained height position, and it is interior and mutual therewith that steel wire 4 is set to embedded groove 31
It supports.In this way, using lever principle, so that expansion 3 bottom of valve is more laborsaving when opening.
The expanding method of the utility model is introduced below in conjunction with specific embodiment.
Embodiment 1
The expanding method of the present embodiment the following steps are included:
The self-locking anchor head of easy expanding is protruded into bottom hole in substrate surface prebored hole by S1;
S2 pushes away casing 2 along 1 outer wall of anchor pole down, until protrusion 30 is caught in groove 10;
S3 takes out casing 2, and injecting paste material is injected in hole.
Embodiment 2
The expanding method of the present embodiment the following steps are included:
A1 injects injecting paste material in substrate surface prebored hole in hole;
The self-locking anchor head of easy expanding is protruded into bottom hole by A2;
A3 pushes away casing 2 along 1 outer wall of anchor pole down, until protrusion 30 is caught in groove 10, takes out casing 2.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on
Within the protection scope of type.
