Embodiment
In order to make those skilled in the art further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, accompanying drawing only provide with reference to and usefulness is described, be not to be used for limiting the utility model.
Fig. 2, Fig. 3 and Fig. 4 are respectively the utility model first embodiment's three-dimensional exploded view, combination schematic representation and assembled sectional view.The utility model provides a kind of improved packing screw structural, as Fig. 2, Fig. 3 and shown in Figure 4, includes a screw body 10, a packing assembly 20 and a Coupling 30, wherein:
Screw body 10 is a cylindrical body, and heart place has a screw section 11 therein, and screw section 11 can be an internal thread.Screw body 10 two ends have extended a shank 12 and a junction 13 respectively.Shank 12 can be the shape of regular hexagon or square, is a regular hexagon in the present embodiment, and it can be for the rotation of tool holder such as open-end wrench.Joint 13 can be a circular shaft, offers a recess 131 (as shown in Figure 5) in its end face center, and the riveted that is beneficial to joint 13 connects.
Fig. 5 and Fig. 6 are respectively user mode schematic representation () and (two) of the utility model when being used for fixing body.As Fig. 5 and shown in Figure 6, elder generation's preboring one blind hole 41 on a wall surface 40 during construction, one end of packing screw of the present utility model is placed the ingress of blind hole 41, use a strike instrument (as: iron hammer) directly to knock a shank 12 of screw body 10 again, knock in the blind hole 41 this packing screw also fixing, because the bottom in blind hole 41 is developed in the bottom surface of Coupling 30, in the process that screw body 10 moves, packing assembly 20 is advanced to Coupling 30 to be pressed into, the cambered surface 23 of packing assembly 20 is outwards backed down and embedded on the internal face of blind hole 41 by the conical surface of Coupling 30, reach strong fix.The screw section 11 of screw body 10 can connect for the retaining ring 50 of a standard size, and retaining ring 50 has a bending hook part 51 and a spiro tooth part 52.Bending hook part 51 is a circular shape, can match with the excircle of the body (as: water pipe, gas pipe etc.) of various different purposes.Spiro tooth part 52 can be fixedlyed connected by screw thread mutually with the screw section 11 of screw body 10.With the solid excircle of bending hook part 51 buttons at body, and spiro tooth part 52 is being aligned the screw section 11 of screw body 10, with a shank 12 of instrument or the direct rotation screw body 10 of hand, it is mobile that retaining ring 50 is drawn close to wall surface 40 directions, thereby body is fixedly mounted.
Fig. 7 is the utility model second embodiment's a assembled sectional view.As shown in Figure 7, the joint 13 of screw body 10 is made of large and small waney hole 132,133, and the front end of packing assembly 20 is provided with protruding axle 25 and one screw 26.Protruding axle 25 can insert in the macroscopic void 132 of screw body 10, make the small holes 133 of screw 26 corresponding to screw body 10, again screw is inserted in the small holes 133 of screw body 10 and screw in the screw 26 of packing assembly 20, screw body 10 and packing assembly 20 are closely linked into an integrated entity, but screw body 10 can produce mutual rotation with packing assembly 20.
In sum, improved packing screw structural of the present utility model has following advantage: because screw body of the present utility model is provided with a shank, can directly it be knocked in the hole of wall surface with instrument, in installation process, recombinant need be do not dismantled earlier, engineering time and cost can be significantly shortened.This screw body and Coupling are for separating setting, and in screw body rotating process, this Coupling can't produce reciprocal moving, and therefore can not make this packing screw outwards be extracted and come off.The use that can cooperatively interact with the retaining ring of a standard size of this screw body, only need be on wall surface when the fixed installation body preboring one blind hole, can reduce the usage quantity of packing screw.
Improved packing screw structural of the present utility model has practicability, novelty and creativeness, structure of the present utility model also never sees like product and public use, more do not publish before the application on any publication, meet the requirement of utility application fully.
The above only is embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are done, or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope that the utility model contains.
