Abstract
The utility model relates to an expansion pin, which discloses an expansion fastening connector that is used on walls. The expansion pin comprises an expansion sleeve and an expansion pin. The expansion pin is characterized in that one end of the expansion sleeve is provided with internal screw threads and a connector, of which the screw threads are combined with the internal screw threads. The other end of the expansion sleeve is provided with a cracked slot. The expansion pin has the advantages of high installation speed and convenient use. The expansion pin can be widely used for the connection on various walls.
Description
The utility model relates to a kind of expansion fastening connection piece, particularly relates to a kind of expansion fastening connection piece that is used on the wall.
Before the applying date, the known widely used expansion fastening connection piece that is used on the wall is an EXPANSION ANCHOR BOLTS, and it is made of expansion set, screw bolt and nut.Mainly there is the shortcoming that installation rate is slow, use inconvenience in it.
The purpose of this utility model provide a kind of installation rate fast, easy to use be used for expansion fastening connection piece on the wall.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of new structure expansion pin of the present utility model comprises expansion set and the pin that expands, and it is characterized in that a end at described expansion set is provided with internal thread and has and the be harmonious link of screw thread of this internal thread, has at the other end of described expansion set and splits groove.The purpose that internal thread and link are set at an end of above-mentioned expansion set is to play interconnect function.Having the purpose of splitting groove at the other end of above-mentioned expansion set is that this end of guaranteeing described expansion set pin that can be expanded strut, thereby the quick distending of expansion set is fixed.
The utility model by said structure, owing to use the pin swelling means of fixation that expands, and be provided with at an end of expansion set and split groove, thereby make the utility model fast swelling fix, simultaneously since an end of expansion set be provided with internal thread and have and the be harmonious link of screw thread of this internal thread, thereby make the utility model can realize linkage function flexibly, so the utlity model has installation rate advantage fast, easy to use.
Below in conjunction with the drawings and specific embodiments, the utility model is done further detailed description.
Fig. 1 is the utility model embodiment's a sectional view;
Fig. 2 is the utility model embodiment's a right elevation.
Embodiment: as shown in Figure 1 and Figure 2, a kind of new structure expansion pin comprises expansion set 1 and the pin 2 that expands, and is provided with internal thread 3 and has and the be harmonious link 4 of screw thread of this internal thread 3 at an end of described expansion set 1, have at the other end of described expansion set 1 and to split groove 5, split groove 5 and be cross recess.
On wall, open earlier a hole during use, expansion set 1 is assembled with the pin 2 that expands put into the hole together, impact the pin 2 that expands, expansion set 1 distending is fixed, then with in the link 4 screw-in expansion sets 1 with a lance.
