Abstract
The utility model relates to an expansion screw nut, belonging to multipurpose installing structural members. The expansion screw nut is mainly used for the installation of safety door against burglary, and besides, the expansion nut can also be used to install or fix heavy objects on foundation structural members such as brick walls, concrete members, cement floor, etc. The expansion screw nut mainly comprises a conical pin 2, a screw nut main body 1, a gasket 3 and a screw bolt 4. The utility model is characterized in that one end of the screw nut main body 1, which is jagged is opened with a cross slot; the inner hole of the screw nut main body is matched with the conical pin; one end of the internal screw threads in the screw nut main body is used to fix object by the connection with the screw bolt 4.
Description
The utility model belongs to a kind of multipurpose mounting structure spare, and it is mainly used in the installation of anti-theft safety door, also can be used on the basic components such as brick wall, concrete member, cement floor installing or fixing weight.
Existing mounting structure spare adopts the EXPANSION ANCHOR BOLTS (see figure 3) more at large, and it mainly is made up of bolt body 5, expansion tube 6, packing ring 3, spring washer 7 and nut 8.(see figure 4) when EXPANSION ANCHOR BOLTS is used for the anti-theft safety door installation, must be special-shaped square steeel tube at first at doorframe 10(material) go up and weld angle steel 9, imbed and tighten with nut 8 after bolt body 5 in the body of wall 11 are passed mounting hole on the angle steel 9, this nut 8 exposes outside doorframe 10, gives removable visual sense.
The purpose of this utility model then is to design for the above-mentioned shortcoming that overcomes EXPANSION ANCHOR BOLTS.It is used for anti-theft safety door when installing, and only needs the hole by accomplishing fluently in advance on the steel pipe doorframe, directly doorframe is anchored on body of wall, and it is fastening imbeds in the doorframe with bolt head, can't dismantle when safety door is shut.
The utility model technical solution:
The utility model mainly is made up of nut main body 1, taper pin 2, packing ring 3 and bolt 4.Nut main body 1 has a jagged end and has cross recess, and its endoporus and taper pin 2 couplings are when taper pin 2 is squeezed into, the outside spreading in fluting position, make it fixing with body of wall 11, the other end of nut main body 1 has internal thread, and its effect is by linking and fixed object with bolt 4.
The utility model has the advantages that: easy to use, rational in infrastructure, solid and reliable.Be particularly useful for the installation of anti-theft safety door and the occasion of using the EXPANSION ANCHOR BOLTS inconvenience.

Fig. 2 is the left side view of expanding nut structural drawing.
Fig. 3 is the EXPANSION ANCHOR BOLTS structural drawing.
Fig. 4 is the sectional drawing of EXPANSION ANCHOR BOLTS when being used for safety door and installing.
Fig. 5 is the sectional drawing of expanding nut when being used for safety door and installing.
Fig. 6 is an expanding nut component part exploded view.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is when the installation that is used for anti-theft safety door, at first should select for use the drill hammer identical or smaller on body of wall 11, to punch with nut main body 1 external diameter, its degree of depth generally should be not less than the length of nut main body 1, then nut main body 1 being had cross recessed one end inserts in the porthole, again taper pin 2 is squeezed into fluting position to nut main body 1, make the outside spreading in nut main body 1 fluting position, to reach the purpose of fixing, then the doorframe 10 that is fixed is fixed together with nut main body 1 binding by bolt 4, packing ring 8 with body of wall 11.
The utility model can be made into series product, to adapt to the object of fixing various different force requests.
