Description

Quick installed nail

The utility model relates to the mechanical fasteners technical field, especially relates to a kind of expansion principle of utilizing object is carried out fastening expandable nail.

At present, the most ripe commercially available expandable nail, its structure mainly is made of swell fixture body and expansion sleeve and nut, and its working principle is: the expansion sleeve of inserting the expandable nail in nail hole is being oppressed by fastener, passes through rotary nut, pulling expandable nail body, by expandable nail body wedge end, " pawl " of carving the distending expansion sleeve and hole wall " are critical " and realize fasteningly, and the major defect of this expandable nail is: 1, operation inconvenience and operating time are long, especially during hanging operation, it is very painstaking to work; 2, after fastening the finishing, the screw that protrudes fastener is oversize, forms potential safety hazard; When 3, expandable nail is not critical with hole wall, both do not fall nut down in inflation process, can not pull out expandable nail yet, be unfavorable for the replacing of fastener; 4, boring is installed inconvenient greater than bolt specification.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of simple to operate, operating time weak point, no expandable nail potential safety hazard are provided, are beneficial to the expandable nail that fastener is changed.

The purpose of this utility model is achieved in that

The utility model is made up of body, screw thread, nail hole, cross recess, nail, nut and cleft hand, be respectively arranged with nail hole and cross recess before and after in body, outer surface with respect to the body of following closely the hole is provided with screw thread, the outer body of cross recess forms cleft hand, when fastening object, nut screwing formula ground is fixed as one with body, and nail is fixed in the nail hole of body, and its head is inserted into the interior distending cleft hand of cross recess and is fixed on the datum hole inwall.

The utility model has following advantage with respect to prior art:

Because the utility model is provided with nail hole and cross recess, utilize the cross recessed special construction, make the body formation cleft hand of its corresponding part, only need during operation nail is inserted in the nail hole, the hammer of exerting oneself goes into can realize fastening, so install very convenient quick; Ding end is all inserted in the nail hole simultaneously, can not cause potential safety hazard; Also be easy to simultaneously the replacing of fastener.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the elevational cross-sectional view of body of the present utility model;

Fig. 2 is the elevational cross-sectional view of behaviour in service of the present utility model;

Fig. 3 is an A-A face sectional view of the present utility model;

Fig. 4 is a B-B face sectional view of the present utility model;

Fig. 5 is another embodiment's of the utility model a elevational cross-sectional view.

This Quick installed nail is made up of body 1, screw thread 2, nail hole 3, cross recess 4, nail 5, nut 6, cleft hand 7, be respectively arranged with nail hole 3 and cross recess 4 before and after in body 1, outer surface with respect to the body 1 of following closely hole 3 is provided with screw thread 2, form cleft hand with respect to cross recess 4, body 1, when fastening object, nail 5 is inserted in the nail hole 3, and its head penetrates the cross recess 4 interior swollen cross recesses of opening is fixed on the datum hole inwall cleft hand 7, nut 6 revolving types link to each other with the end of body 1, and fixing fastened object.

Another embodiment of the present utility model is that the right-hand member at body 1 is provided with incorporate cap 8, in installation process, cap 8 can be directly fixing fastener.
