Description
Technical field
It the utility model is related to new expanding screw adjusting screw apparatus field, the expansion that especially a kind of arm extending type can be recycled
Screw equipment.
Background technology
Expanding screw adjusting screw used in everyday, is mostly that afterbody has crack, the screw for strutting afterbody by internal-flange bolt and expanding
Nail, this screw have following several respects deficiency in practical application：1st, the volume of afterbody expansion is very limited, is unfavorable for fixed screw
Rivet nut portion.It can not expand for second and utilize again if the 2, this screw expansion is once rear invalid or replaces position, after taking-up, in fact
Border is mostly disposable, very uneconomical.If the 3, running into loose cement wall, at all can not fixed screw rivet nut portion, have
When cannot replace position again, to installation equipment belt it is difficult.
Utility model content
To solve the above problem present in the prior art and actual conditions, the utility model provides a kind of arm extending type expansion
Screw, including bolt, nut, screw rivet nut, bolt coat, bolt include the horizontal handle at top, and the bolt coat casing is set
Outside bolt top side, bolt coat bucket includes the integrated metal transverse arm of two lateral wall institute bands and the horizontal overcoat at top
Cylinder, the horizontal outer sleeve are set on horizontal handle；The screw rivet nut is hollow type, and top is taper, and the horizontal stroke of bolt coat bucket is outer
Sleeve and lateral wall are located in the cavity of screw rivet nut, and the afterbody of the screw rivet nut is equipped with through hole, and screw rivet nut is equipped with both sides
The hole for the flexible metal transverse arm that wall is opened, the nut match with bolt thread and connect with the afterbody of screw rivet nut.
Preferably, the material of the transverse arm is iron or steel.
Preferably, the head of the bolt is taper.
The utility model provides the expanding screw adjusting screw that a kind of arm extending type can recycle, it is necessary to extended multiple gold when expanding
Belong to transverse arm, prick on the cement wall around screw, 1-2 times of increase screw volume, metal of retracting when not used can be expanded
Transverse arm, restores to the original state, while is taper at the top of screw, also using hammering within the walls.The present invention has very strong practicality and warp
Help benefit, it is while technically simple, it is easy to make, cost will not be increased.
Brief description of the drawings
Further illustrate with reference to the accompanying drawings and detailed description：
Fig. 1 is the longitudinal sectional drawing of the utility model arm extending type expanding screw adjusting screw unswollen state.
Fig. 2 is the longitudinal sectional drawing of the utility model arm extending type expanding screw adjusting screw swelling state.
Embodiment
As shown in Figure 1, 2, the utility model discloses a kind of arm extending type expanding screw adjusting screw, including bolt 1, nut (nut)
2nd, screw rivet nut 3, bolt coat 4；Bolt 1 includes the horizontal handle 1-1 at top；It is horizontal that the body of bolt 3 is equipped with the flexible metal opened two side
The hole 3-1 of arm；Bolt coat bucket 4 includes the integrated metal transverse arm 4-1 of two lateral wall institute bands and the horizontal overcoat bucket 4-2 at top；
The top tapered of screw is beneficial to hammer within the walls；The head of bolt is also taper, and protection screw thread is beneficial to when external force impacts.
A kind of arm extending type expanding screw adjusting screw operation principle：Bolt is driven to be moved to outer within the walls by rotary nut (nut),
Bolt promotes the bolt coat of set on the outside to move by the horizontal handle at top, so as to drive the metal transverse arm on bolt coat in spiral shell
Stretching motion in the hole in adjusting screw body portion, reaches expansion or unexpanded state.
A kind of arm extending type expanding screw adjusting screw uses step：(1) punched using electric drill in cement wall surface.(2) will be unexpanded
The screw of state is hammered into hole.(3) nut (nut) 2 is rotated clockwise with instrument.(4) bolt 1 is outwards divided a word with a hyphen at the end of a line, and passes through top
Horizontal handle 1-1 drive horizontal overcoat bucket 4-2, so as to drive bolt coat bucket 4 also outwards to divide a word with a hyphen at the end of a line.(5) it is moved out in bolt coat bucket 4
During row, the integrated metal transverse arm 4-1 of both sides stretches out outside by the hole 3-1 of screw body sidewall, pricks the water of surrounding
In mud wall, so as to fix screw rivet nut portion.(6) during expanding screw adjusting screw to be removed, with instrument rotary nut (spiral shell counterclockwise
It is female) 2, other operational process and swelling state operational process contrast, screw finally return to original unswollen state, use
Instrument takes out expanding screw adjusting screw, can reuse.
The present invention is not limited to other several iron (steel) transverse arm expanding screws only by taking six iron (steel) transverse arm expanding screw adjusting screws as an example
Adjusting screw.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
