Abstract
The utility model discloses a built-in bolt, which comprises a screw rod used for being screwed into an object and a bolt head detachably connected with the screw rod, and the screw rod is provided with a concave screw rod connecting part. According to the utility model, the bolt head can be separated from the screw rod after the screw rod is screwed into a board, therefore, screw connecting structure is not damaged and the screw head is prevented from being exposed.
Description
Technical field
The utility model relates to a kind of connection set, particularly a kind of built-in screw that is applicable to household.
Background technique
When processing furniture such as desk or cupboard, often need to use screw that different planks is linked together.
Present screw generally includes screw rod and the screw head that links together, in case after screw hammered into plank, its screw head was exposed to the outside usually, so people need to knock screw head usually, it is embedded plank inner.
Yet, adopt said method that the way that screw head embeds plank inside is imappropriate, because this will destroy the screw connection structure of screw and plank.
Summary of the invention
The purpose of this utility model provides a kind of built-in screw that screw connection structure can avoid again screw head to expose that neither destroys.
Above-mentioned purpose of the present utility model is achieved in that a kind of built-in screw, comprising:
Be used for screwing in the threaded stem of object;
The screw head of described threaded stem removably connects.
Preferably, described threaded stem has the threaded stem joint of indent.
Screw head of the present utility model can separate with threaded stem, thereby not destroy screw connection structure after threaded stem screw in plank, avoids again screw head to expose simultaneously.
Preferably, described screw head joint has the screw head joint of protrusion.
Preferably, described threaded stem joint is the screw with internal thread.
Preferably, described screw head joint is for having externally threaded screw rod.
Preferably, described threaded stem joint is polygonal groove.
Preferably, described screw head is the projection that matches with described polygonal groove.
Preferably, described threaded stem joint is the triangle groove.
Preferably, described screw head joint is triangle convex.
Built-in screw of the present utility model also comprises for the filling member of inserting described threaded stem joint.
With respect to prior art, the utlity model has: do not destroy screw connection structure, avoid screw head to expose and the technique effect of use.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of built-in screw of the present utility model;
Fig. 2 is the screw head formation schematic diagram of built-in screw of the present utility model.
Embodiment
Fig. 1 has shown the structure of built-in screw of the present utility model, as shown in Figure 1, comprising:
Be used for screwing in the threaded stem 1 of object;
The screw head 2 of described threaded stem 1 removably connects.
Preferably, described threaded stem 1 has the threaded stem joint 12 of indent.
Screw head 2 of the present utility model can separate with threaded stem 1, thereby not destroy screw connection structure after threaded stem 1 screw in plank, avoids again screw head to expose outside plank simultaneously.
In addition, screw head 1 of the present utility model has the screw head joint 12 of protrusion.
In addition, described threaded stem joint 11 is for having the screw of internal thread.Described screw head joint 21 is for having externally threaded screw rod.
In addition, described threaded stem joint 11 is polygonal groove, and screw head joint 21 is the projection that matches with described polygonal groove.
In addition, threaded stem joint 11 is the triangle groove, and screw head joint 21 is triangle convex.
On the other hand, built-in screw of the present utility model also comprises for the filling member of inserting described threaded stem joint.This filling member is preferably soft material.
The utility model at first combines screw head 2 and threaded stem 1 in use, among the screw screw-in plank of recycling screw-driver after will this combination, then takes out screw head 2, will screw in the sinking space that threaded stem causes with filling member and fill up.
Technique effect of the present utility model is very significant, does not only destroy screw connection structure but also can also avoid screw head to expose.
Although above the utility model is had been described in detail, the utility model is not limited to this, and those skilled in the art of the present technique can carry out various modifications according to principle of the present utility model.Therefore, all modifications of doing according to the utility model principle all should be understood to fall into protection domain of the present utility model.
