It is still another object of the present invention to provide a novel set screw.
In order to achieve the above object, the utility model provides a novel set screw, a serial communication port, include:
the bolt head, the shank of bolt, fixed bolt pole and arc control piece, the shank of bolt bottom has the bolt hole, the bolt hole with the shank of bolt is concentric, the diameter of bolt hole does half of shank of bolt diameter, the degree of depth of bolt hole equals the diameter of bolt hole, bolt hole inner wall is provided with the screw thread, the diameter of fixed bolt pole with the diameter of bolt hole is the same, be provided with the screw thread on the fixed bolt pole, the distance between the arc control piece left and right sides both ends is than the little 1mm of diameter of shank of bolt, the radian of arc control piece equals the radian of its fixed steel pipe, the width of arc control piece equals half of distance between both ends about its body.
Preferably, the bolt head, the bolt rod, the fixed bolt rod and the arc-shaped control piece are all made of metal materials.
Preferably, the bolt head is hexagonal in shape.
Preferably, one end of the bolt rod with the bolt inner hole is chamfered.
Preferably, the threads on the bolt inner hole and the fixed bolt rod are triangular threads.
The utility model discloses at least, include following beneficial effect:
1. a novel holding screw, its design that adopts two parts structure utilizes the diameter of bolt pole poor, can the quick fixation steel pipe, and difficult pine takes off.
2. A novel holding screw, its simple structure, reasonable in design is fit for using widely.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
Drawings
Fig. 1 is a schematic structural view of a novel set screw according to the present invention.
In the figure: 1. the bolt head, 2, the bolt rod, 201, the bolt hole, 3, the fixed bolt rod, 4, the arc control piece.
Detailed Description
The present invention is further described in detail below with reference to the drawings and examples so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1, one embodiment of the present invention provides a novel set screw, which includes:
bolt head 1, shank of bolt 2, fixed shank of bolt 3 and arc control piece 4, 2 bottoms of shank of bolt have bolt hole 201, bolt hole 201 with shank of bolt 2 is concentric, the diameter of bolt hole 201 does half of the 2 diameters of shank of bolt, the degree of depth of bolt hole 201 equals the diameter of bolt hole 201, bolt hole 201 inner wall is provided with the screw thread, the diameter of fixed shank of bolt 3 with the diameter of bolt hole 201 is the same, be provided with the screw thread on the fixed shank of bolt 3, the distance between the both ends is than about arc control piece 4 the diameter of shank of bolt 2 is little 1mm, the radian of arc control piece 4 equals the radian of its fixed steel pipe, the width of arc control piece 4 equals about its body half of the distance between the both ends.
Further, the bolt head 1, the bolt rod 2, the fixed bolt rod 3 and the arc-shaped control sheet 4 are all made of metal materials.
Further, the bolt head 1 is hexagonal in shape.
Further, one end of the bolt rod 2 with the bolt inner hole 201 is chamfered.
Further, the threads on the bolt inner hole 201 and the fixed bolt rod 3 are triangular threads.
The utility model discloses a use method does: when the steel pipe fixing device is used, the fixing bolt rod 3 is temporarily fixed in the bolt inner hole 201, then the fastening bolt is placed in a steel pipe hole to be fixed, the arc-shaped control piece 4 is in close contact with the outer wall of the steel pipe, the bolt head 1 is screwed until the steel pipe is fixed, the fixing bolt rod 3 can be screwed into the bolt inner hole 201 along with screwing of the bolt head 1 into the bolt inner hole, but the diameters of the bolt rod 2 and the fixing bolt rod 201 are different, the depth of the bolt rod 2 which can be screwed into a circle is 2 times of the depth of the fixing bolt rod 201 which can be screwed into a circle, and the steel pipe can be fixed by utilizing the difference.
While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application suitable for this invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details shown and described herein without departing from the general concept defined by the claims and their equivalents.
