Description
Technical field
The utility model relates to a kind of combined suspension crab-bolt.
Background technique
Existing suspension crab-bolt adopts common expansion anchor usually, because the expansion sleeve cylindrical is more smooth; Rotate easily during installation, be difficult to be inflated fixing, and adopt nut fastening in the end; Time has been grown loosening easily, its inner screw rod that adopts, and inconvenience connects other fixed block once more.Existing expansion anchor generally all expands in Lower Half during installation, and expansion is not played on top; And because the wall thickness of expansion sleeve is thinner, the easy deformation that is stressed during installation at first is to have caused inconvenient installation; Can't be installed to predetermined depth, next has reduced the fixed performance of crab-bolt.
The model utility content
To the deficiency that above-mentioned existing technology exists, the purpose of the utility model is to provide a kind of being easy to that the combined suspension crab-bolt of reliable performance is installed.
In order to achieve the above object, a kind of combined suspension crab-bolt of the utility model comprises expansion rod, expansion sleeve; Expansion rod one end has the tapering head; Expansion sleeve circumferentially is evenly equipped with some locating slots at inflating end, has the positioning bar that adapts to said locating slot on the conical surface of said expansion rod tapering head, has outside thread on the body of rod of this expansion rod; Said combined suspension crab-bolt also comprises an adapter sleeve; This adapter sleeve one end has rotary-tightening device, has internal thread on the adapter sleeve inwall, and the body of rod of said expansion rod wears the expansion sleeve rear thread and connects adapter sleeve.
Further, said expansion sleeve circumferentially has Device for preventing rotation, and this Device for preventing rotation is the decorative pattern of wedge shape convexity or convex-concave shape.
Further, said adapter sleeve middle part has strengthens section, and this reinforcement section and adapter sleeve are made into integration.
Further, the rotary-tightening device of said adapter sleeve is the mother that screws, and cooperates the mother that screws to be provided with pad, this pad and adapter sleeve split setting or be wholely set.
Further, the said adapter sleeve end that has the rotary-tightening device external piece that can be threaded.
Further, the inflating end of said expansion sleeve is provided with locating slot, and the other end is provided with corresponding technology groove, and the flute length of locating slot is greater than the flute length of technology groove.
The utility model has been broken through the conventional design scheme of expansion anchor, and with the expansion sleeve split setting of crab-bolt, the first half repacks inner screwed adapter sleeve into; Lower Half keeps the function of expansion sleeve, and adapter sleeve is the tension expansion rod when crab-bolt is installed, and it is fixing that crab-bolt is expanded; Adapter sleeve still leaves one section space after the installation, and joint outer part can be installed, because the reach in the expansion sleeve is longer; So improved the firm performance of the combination of crab-bolt, the back be installed be difficult for loosening; The expansion sleeve of the utility model is set up Device for preventing rotation at cylindrical, and the wedge shape that is provided with the protrusion surface is protruding, and this convexity can be embedded in the concrete hole wall of mounting hole, has improved surface friction drag, the convenient installation; The body of rod of the expansion rod of the utility model is shorter, under the prerequisite that satisfies use, has saved Manufacturing material.

Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to structure, characteristic and the effect of the utility model specify as after.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 7ly designed one of embodiment by the utility model, in this embodiment, a kind of combined suspension crab-bolt; Comprise expansion rod 3, expansion sleeve 2, expansion rod 3 one ends have tapering head 3-1, and expansion sleeve 2 circumferentially is evenly equipped with some locating slot 2-1 at inflating end; Have the positioning bar 3-2 that adapts to locating slot 2-1 on the conical surface of expansion rod tapering head 3-1; Several that the quantity of locating slot 2-1 and positioning bar 3-2 can be arranged to respectively be uniformly distributed with, adopt 4 in this embodiment by for example 2-6; Certainly also can adopt more than 6 settings according to actual needs, have outside thread on the body of rod of this expansion rod.
This combined suspension crab-bolt also comprises an adapter sleeve 1, and these adapter sleeve 1 one ends have female 1-1 that screws, and have internal thread on adapter sleeve 1 inwall, and expansion sleeve 2 is set on the body of rod of expansion rod 3, the body of rod of expansion rod 3 adapter sleeve 1 that is threaded.
In general, the outside diameter of the outside diameter of adapter sleeve 1 and expansion sleeve 2 is equal to, and can certainly adopt anisodiametric cylindrical, but will guarantee that adapter sleeve 1 and expansion sleeve 2 adjacent ends can be stablized leans.
The expansion sleeve 2 of the utility model can also adopt following setting, is provided with locating slot at inflating end, and the other end is provided with corresponding technology groove, and the shape of technology groove is similar with locating slot, but flute length less than locating slot, technology groove helps the expansion of expansion sleeve 2.
