Abstract
The utility model discloses a kind of recycling-type high-strength expansion bolt, comprise: expansion rod and expansion sleeve, described expansion sleeve is provided with multiple expansion nut, described expansion rod is provided with multiple expansion rod nut, described expansion sleeve is arranged on expansion rod outside, and expansion nut is positioned at the below of expansion rod nut, the bottom of described expansion rod is exposed to expansion sleeve.By the way, the utility model recycling-type high-strength expansion bolt, can improve structural strength, not fragile, can repeatedly use, easy to use.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of recycling-type high-strength expansion bolt.
Background technique
The EXPANSION ANCHOR BOLTS generally used at present is formed primarily of screw rod, expansion tube, hexagon nut, compression spring, pad, during use, tighten hexagon nut, make in the screw rod press-in expansion tube of band cone, expansion tube swells and is fastened in wall, this EXPANSION ANCHOR BOLTS is difficult to extract, even if use powerful being extracted, also body of wall will be damaged, and screw rod and expansion tube are also difficult to be separated, cannot reuse, cause the waste of resource.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of recycling-type high-strength expansion bolt, can improve structural strength, not fragile, can repeatedly use, easy to use.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of recycling-type high-strength expansion bolt, comprise: expansion rod and expansion sleeve, described expansion sleeve is provided with multiple expansion nut, described expansion rod is provided with multiple expansion rod nut, described expansion sleeve is arranged on expansion rod outside, and expansion nut is positioned at the below of expansion rod nut, and the bottom of described expansion rod is exposed to expansion sleeve.
In the utility model preferred embodiment, the top of described expansion rod is outer-hexagonal body, and bottom is cone.
In the utility model preferred embodiment, the quantity of described expansion nut is 2, and is symmetricly set on the upper end of expansion sleeve, and described expansion nut is hexagon nut.
In the utility model preferred embodiment, the quantity of described expansion rod nut is 2, and is symmetricly set on the upper end of expansion rod, and described expansion rod nut is hexagon nut.
The beneficial effects of the utility model are: the utility model recycling-type high-strength expansion bolt, can improve structural strength, not fragile, can repeatedly use, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model recycling-type high-strength expansion bolt one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, expansion rod, and 2, expansion sleeve, 3, expansion nut, 4, expansion rod nut.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of recycling-type high-strength expansion bolt, comprise: expansion rod 1 and expansion sleeve 2, described expansion sleeve 2 is provided with multiple expansion nut 3, described expansion rod 1 is provided with multiple expansion rod nut 4, it is outside that described expansion sleeve 2 is arranged on expansion rod 1, and expansion nut 3 is positioned at the below of expansion rod nut 4, and the bottom of described expansion rod 1 is exposed to expansion sleeve 2.
In addition, the top of described expansion rod 1 is outer-hexagonal body, and bottom is cone.
In addition, the quantity of described expansion nut 3 is 2, and is symmetricly set on the upper end of expansion sleeve 1, and described expansion nut is hexagon nut.
In addition, the quantity of described expansion rod nut 4 is 2, and is symmetricly set on the upper end of expansion rod 1, and described expansion rod nut 4 is hexagon nut.
The concrete using method of the utility model recycling-type high-strength expansion bolt is as follows: knock in the hole accomplished fluently by EXPANSION ANCHOR BOLTS entirety, nut is tightened, brill core machine fixed bearing is inserted in and sets, to screw on again instrument hold-doun nut, after using, unload instrument hold-doun nut, then expansion rod is impacted gently, make to occur between expansion rod and expansion sleeve loosening, be enclosed within by spanner on the nut on expansion sleeve, left rotation and right rotation applies an outside power simultaneously, knows that prize expansion sleeve takes off, then take off expansion rod, repeat above-mentioned steps and reusable.
Be different from prior art, the utility model recycling-type high-strength expansion bolt, can improve structural strength, not fragile, can repeatedly use, easy to use.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
