In view of the deficiencies of the prior art, the present invention provides a kind of novel screws with movable screw cap.
The present invention is realized by following technological means solves above-mentioned technical problem：
A kind of novel screw with movable screw cap, including stud, the upper end of the stud are provided with the square of both ends open
Shape hole, the stud are both provided with limiting slot at the both ends open of rectangular opening, and the limiting slot is horizontally disposed, and the square
The distance of limiting slot in the vertical direction at the both ends open of shape hole is identical with the diameter of stud；It is equipped in the rectangular opening
Movable block, the movable block can be freely movable in rectangular opening, and the movable block is rectangle identical with rectangle hole shape,
Setting is there are two limit protrusion on the movable block, the positions of described two limit protrusions respectively at rectangular opening both ends open
The position of limiting slot is corresponding.
Preferably, a kind of novel screw with movable screw cap, the rectangular opening is vertically arranged, and institute
The length for stating movable block is more than the diameter of stud.
Preferably, the length of a kind of novel screw with movable screw cap, the movable block is that stud is straight
1.75-2 times of diameter.
Preferably, a kind of novel screw with movable screw cap is provided on the bottom face of the stud
The both ends of index line, the index line are respectively directed to two openings of rectangular opening.
The advantage of the invention is that：The screw with movable screw cap of the present invention, which can be used in, to be needed to stay in cap nut
The connection of two articles when in closed cavity solves the problems, such as that normal screws oncomelania cap is difficult to across wire hole so that screw
Application range it is wider, when use, is more convenient.
Further, since the length of movable block is more than the diameter of stud, and the 1.75- that the length of movable block is stud diameter
2 times, ensure the extended rectangular opening in the both ends of movable block, and that stretches out is of convenient length, ensures the fastness after screw is fixed.

Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
A kind of novel screw with movable screw cap, including stud 1, the upper end of the stud 1 are provided with both ends and open
The rectangular opening 2 of mouth, the stud 1 are both provided with limiting slot 3 at the both ends open of rectangular opening 2, and 3 level of limiting slot is set
It sets, and the distance of the limiting slot 3 at 2 both ends open of the rectangular opening in the vertical direction is identical with the diameter of stud 1；Described
Movable block 4 is installed in rectangular opening 2, the movable block 4 can the freely activity in rectangular opening 2, the movable block 4 is and square
The identical rectangle of 2 shape of shape hole, there are two limit protrusion 5, the positions of described two limit protrusions 5 for setting on the movable block 4
It sets corresponding with the position of limiting slot 3 at 2 both ends open of rectangular opening respectively.
It in practical applications,, first will be movable when encountering the application requirement such as Fig. 1 by taking Fig. 1 in background technology as an example
Block is vertical to be put into rectangular opening, and two on movable block limit protrusion is respectively placed in its corresponding limiting slot, is then held
Firmly wire hole is stretched into the upper end of stud by the lower end of stud, and the upper end of stud is stretched into the cavity of object A, then rotates spiral shell
Column, due to gravity（Due to having used gravity, screw of the invention is mainly used for screw and is horizontally or diagonally arranged
The case where；If screw is vertically arranged when fixed, movable block is difficult to move, the feelings that the not applicable screw is placed vertically
Condition）, movable block movement, at this time the both ends of movable block stretch out rectangular opening, then thru-bolt and will be twisted with the nut that stud coordinates
Tightly, due to the position-limiting action of two limit protrusions, the length that rectangular opening is stretched out at movable block both ends is identical, at this point, movable block plays
The effect of cap nut achievees the purpose that connect object A with object B and stays cap nut in the cavities.Carrying for the present invention is lived
The screw of dynamic cap nut can be used in the connection of two articles when needing to stay in cap nut in closed cavity, solve common spiral shell
Adjusting screw nut is difficult to the problem of across wire hole so that the application range of screw is wider, and when use is more convenient.
Preferably, the rectangular opening 2 is vertically arranged, and the length of the movable block 4 is more than the diameter of stud 1；It is described
The length of movable block 4 is 1.75-2 times of 1 diameter of stud.
Since the length of movable block is more than the diameter of stud, and 1.75-2 times that the length of movable block is stud diameter, it protects
The extended rectangular opening in both ends of movable block is demonstrate,proved, and that stretches out is of convenient length, ensures the fastness after screw is fixed.
Preferably, index line 6 is provided on the bottom face of the stud 1, the both ends of the index line 6 are respectively directed to rectangle
Two openings in hole 2.
Index line is set on the bottom face of stud, can easily observe the direction of rectangular opening opening, be adjusted when easy to use
Rotation position.
The screw with movable screw cap of the present invention can be used in two when needing to stay in cap nut in closed cavity
The connection of object solves the problems, such as that normal screws oncomelania cap is difficult to across wire hole so that the application range of screw is wider, makes
Used time is more convenient；Further, since the length of movable block is more than the diameter of stud, and the length of movable block is stud diameter
1.75-2 times, ensure the extended rectangular opening in the both ends of movable block, and that stretches out is of convenient length, ensures secured after screw is fixed
