Abstract

The utility model relates to an expansion nut, comprising a nut sleeve 1 and an expansion screw bolt 2. The utility model is characterized in that the nut sleeve 1 is provided with a prearranged ruptured zone; the tail end of the expansion screw bolt 2 which is installed in the nut sleeve 1 is cone-shaped; the front end face of the expansion screw bolt is provided with six thousands counter bores. The utility model has the advantages that the expansion nut is provided with all functions of the existing expansion bolts, the application of the expansion bolt is more widely, and besides, the performance of the expansion bolt is more superior.

Description

Nut with expanding sleeve

The utility model relates to a kind of expanding nut.

At present, in construction and installation, and in the family daily life, mounting article mostly adopts most popular EXPANSION ANCHOR BOLTS on the market, and the structure of EXPANSION ANCHOR BOLTS is: at bolt tail one section cone is arranged, the bolt outer cover is equipped with the metallic sheath that an afterbody is processed with predetermined zone of fracture, when moving forward with nut drive bolt, the zone of fracture of metallic sheath afterbody is played fixation by the cone distending.EXPANSION ANCHOR BOLTS is more convenient when fixed object, and application surface is also very wide, but because there is following shortcoming in the problem of working method that its structure is made peace: (1) is because effective active length of EXPANSION ANCHOR BOLTS is definite, so mounting article thickness is restricted.(2) have many objects not allow the outside thing of this object plane to occur being higher than fixedly the time, EXPANSION ANCHOR BOLTS then can't realize this function, as electrical switch is installed, and door and window etc. on the building.

The purpose of this utility model provides a kind of structure more reasonable with regard to being to overcome existing deficiency in the prior art, outside all functions that not only have traditional expansion bolt and had, and use more extensive, the expanding nut that performance is more superior.

The purpose of this utility model realizes by following measure: be processed with predetermined zone of fracture on the nut sleeve, the afterbody that is installed in the cinch bolt in the nut sleeve is taper, is processed with six side's counterbores on its front-end face.

Designed afterbody is that the cinch bolt of taper can be integral structure in the utility model, also can form for the tapered sleeve by suit.

The advantage that the utility model is compared existing EXPANSION ANCHOR BOLTS is: structure is more reasonable, all functions that not only have traditional expansion bolt and possessed, and application area is more extensive, because this expanding nut can be fixed in the wall or the inside of other object, and can become the plane, so can solve some special mounting needs with body surface.For example door and window etc. on the building only needs have openning hole on framework in advance, punches on wall according to the position in hole again, inserts expanding nut, and framework is put well on request, and is directly fixing with screw again.And can select the screw of different length for use according to the thickness of installation object.These advantages all are that EXPANSION ANCHOR BOLTS is incomparable.

The drawing of accompanying drawing is described as follows:

Fig. 1 cuts open figure for the utility model embodiment 1 master.

Fig. 2 cuts open figure for the utility model embodiment 2 master.

The utility model is done to describe in detail below in conjunction with accompanying drawing:

As shown in the figure: the utility model is made up of nut sleeve 1 and cinch bolt 2, wherein, be processed with predetermined zone of fracture on the nut sleeve 1, the afterbody of cinch bolt 2 is a cone structure, this cone structure can be an integral body (as shown in Figure 1) with the cinch bolt body, also can form (as shown in Figure 2), be processed with standard six side's counterbores on the front-end face of cinch bolt 2 by the tapered sleeve 3 that is sleeved on the cinch bolt.

The utility model in use, select for use suitable drill bit to punch will installing on the object earlier, as wall, wood, concrete column etc., in the expanding nut load hole, rotate cinch bolt with hexagon spanner then, cinch bolt then moves forward, predetermined zone of fracture on the nut sleeve will reach the purpose that expands and tighten up, after expanding nut installs by the cone distending of cinch bolt afterbody, according to size, thickness that object is installed, suitably select screw that object is installed and get final product again.

Claims

1, the utility model relates to a kind of expanding nut, it is characterized in that: it is made up of nut sleeve (1) and cinch bolt (2), nut sleeve is processed with predetermined zone of fracture on (1), and the afterbody that is installed in the cinch bolt (2) in the nut sleeve (1) is taper, is processed with six side's counterbores on its front-end face.

2, expanding nut according to claim 1 is characterized in that: the tapering part of cinch bolt (2) afterbody is that the tapered sleeve (3) by suit forms.

3, expanding nut according to claim 1 is characterized in that: the thread section that cinch bolt (2) is anterior and the tapering part of its afterbody are an overall structure.
