Abstract
The utility model discloses an insertion type expansion screw nail, being composed of a screw base, an expansion tube and a screw bolt. The utility model is characterized in that the screw base is provided with a big head and a small head, the small head in inserted into the expansion tube, an inner wall of the screw base is provided with a screw thread, the screw thread matches with the screw bolt and the screw bolt is screwed in from the small head of the screw base inserted into the expansion tube.
Description
A kind of plug-in type swell fixture belongs to building materials field.
The present swell fixture that generally uses on the market, screw base and bolt part are divided into one, and wall external application nut tightens up, because the thickness of wall body difference, swelling degree difference, regular meeting finds in use to install that afterwards exposed parts is too many, influences attractive in appearancely, and is difficult to take off.
The utility model mainly is for overcoming a kind of novel setscrew that above defective designs, and installs the back exposed parts seldom, and the time spent is not easy to dismounting.
Design scheme of the present utility model is:
A kind of plug-in type swell fixture, by screw base, expansion tube, bolt is formed, it is characterized in that one of screw base big one little, the microcephaly inserts in the expansion tube, the screw base inwall has screw thread, and screw thread cooperates with bolt, and bolt screws in from the microcephaly of the screw base of insertion expansion tube.
Describe in detail below in conjunction with accompanying drawing:
A kind of plug-in type swell fixture, by screw base 1, expansion tube 2, bolt 3 is formed, it is characterized in that screw base 1, one big one little, the microcephaly inserts in the expansion tube 2, screw base 1 inwall has screw thread, screw thread cooperates with bolt 3, and bolt 3 screws in from the microcephaly of the screw base 1 of insertion expansion tube 2.
This structure tights a bolt in use, and the screw base inner thread is because to be matched with bolt be to creep into expansion tube and since one of screw base big one little, when major part enters, push expansion tube naturally it fully opened, thereby reach fixedly purpose.Like this, exposed parts only is the bolt part.In addition, the time only need oppositely looser a bolt in dismounting and just can easily transfer to.
The utility model is simple in structure, wide application, and design is unique.
