Abstract
The utility model discloses a cement screw. The rear part of a cement screw body is provided with a screw or screw threads. When the utility model is used, the cement screw is hammered into cement through an iron hammer, and an object can be arranged by using a common screw or a common nut. The installation is convenient, and the object arranged on the utility model can be disassembled. The utility model solves the problem that the cement screw can not be disassembled, and is suitable for arranging the objects which probably need disassembling on the cement.
Description
The utility model relates to a kind of cement nail.
At present, the method for fixed object is with cement nail or setscrew on cement.Cement nail is the object of the outer appearance iron nail made with Hard Alloy Steel, and it is made up of nail point and nail body.Cement nail hammers into cement with iron hammer.Cement nail hammers into conveniently, but can not dismantle.Setscrew is made up of big tail screw, split thimble, pad, compression spring, a nut.During use, on cement, bore a hole with electric hammer earlier, put into setscrew, and screw nut, split thimble is swollen at big tail screw afterbody, thereby setscrew is fixed on the cement.At this moment screw out nut, both can on setscrew, install and fix object.Though this method is detachable, need electric hammer when installing for the first time, not too convenient.
The purpose of this utility model is can not dismantle at above-mentioned cement nail, the first shortcoming not too easily of installing of setscrew, and what provide is a kind of easy for installation, demountable Cement screw.
The utility model is a Cement screw, is realized by following technological scheme, and Cement screw is made up of nail point and nail body, follows closely after one's death that portion is provided with screw thread, and this screw thread can be an internal thread, also can be outside thread.With iron hammer Cement screw is hammered in the cement during use, both available normal screws or nut freely screw in to screw out and have installed and fixed object.
The utility model compared with prior art, its advantage be the CONCRETE SCREWS ailing after one's death portion be provided with internal thread or outside thread, so not only easy for installation for the first time, and the object of installing can be dismantled repeatedly.Fastening piece when being used for the conduct object that installation may need be dismantled on cement.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the overall structure cut-away view of the utility model internal thread form.
Fig. 2 is the overall structure cut-away view of the utility model external thread form.
As shown in Figure 1, the utility model Cement screw 1 is made up of nail point 3 and nail body 9, follows closely body 9 rear portions and is provided with internal thread 4 (internal thread 4 certain must have screw).With iron hammer Cement screw 1 is hammered in the cement 8 during use, both available normal screws 2 freely screws in to screw out and has installed and fixed object.
As shown in Figure 2, the utility model Cement screw 5 is made up of nail point 3 and nail body 9, and nail body 9 rear portions are provided with outside thread 7.With iron hammer Cement screw 5 is hammered in the cement 8 during use, both available plain nut 6 freely screws in to screw out and has installed and fixed object.
Fastening piece when the utility model is used for the conduct object that installation may need be dismantled on cement.
