Description
Technical field
The utility model relates to a kind of fasteners.
Background technique
One end of the body of rod is usually arranged in cap head by existing fastener, and needs two for some special fastening requirements
Head fastens simultaneously, causes existing fastener that cannot be applicable in, and existing firm part can only play fixed function, not have close
The function of leakproof is sealed, even if some firm parts are equipped with sealing glue, but these sealing glues can cover the portion on the body of rod
Divide screw thread, will affect firm effect.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide one kind to be able to carry out bidirectional fastening, not only have
There is sealing and anti-leakage performance, moreover it is possible to guarantee the fastener of fastening effect.
The utility model proposes a kind of fastener, including the body of rod and the cap body that the body of rod middle section is arranged in, institute
It states cap body and circumferentially exceeds the body of rod circumferential direction, the body of rod is divided into the first bar and the second bar by the cap body, it is characterised in that: institute
Stating the first and second bar is threaded rod, and it is recessed that the cap body is equipped with the annular placed for glue towards the side of first bar centre
Slot, the annular groove are connect with the edge-smoothing of the cap body, are formed between the edge of the cap body and the annular groove
Step surface passes through one section of polished rod connection between first bar and the cap body.
Further, the number of threads of first bar is greater than the number of threads of second bar.
Further, the one end of first bar far from the cap body is hexagonal bar.
Further, the depth of the annular groove is the 0.1-0.3 of the cap body thickness.
Further, the length of the polished rod is 1.5-3 times of the annular groove depth.
Further, first bar is identical as the length of second bar.
Further, the length of the hexagonal bar is a quarter of first pole length.
Further, the width of the step surface is the one third of the shank diameter.
According to the above aspect of the present invention, the utility model at least has the following advantages: the fastener is by being arranged cap body in the body of rod
Centre, so that the body of rod is formed the first and second bar, and the first and second bar is threaded rod, so as to realize bidirectional fastening, passes through cap
The design of annular groove on body, can place glue in annular groove, can by the setting of polished rod for sealing and anti-leakage
Guarantee that glue will not cover the screw thread on the first bar, to guarantee fastening effect.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model fastener.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Embodiment one: a kind of fastener, including the body of rod 1 and the cap body 2 that the body of rod middle section is arranged in, the cap body
Circumferential circumferential beyond the body of rod, the body of rod is divided into the first bar 3 and the second bar 4 by the cap body, and first and second bar is equal
For threaded rod, the cap body is equipped with the annular groove 5 placed for glue towards the side of first bar centre, and the annular is recessed
Slot is connect with the edge-smoothing of the cap body, forms step surface 6 between the edge of the cap body and the annular groove, and described the
It is connected between one bar and the cap body by one section of polished rod 7.
The number of threads of first bar is greater than the number of threads of second bar.
The one end of first bar far from the cap body is hexagonal bar 8.
The depth of the annular groove is the 0.1-0.3 of the cap body thickness.
The length of the polished rod is 1.5-3 times of the annular groove depth.
First bar is identical as the length of second bar.
The length of the hexagonal bar is a quarter of first pole length.
The width of the step surface is the one third of the shank diameter.
The fastener makes the body of rod form the first and second bar, and the first and second bar is equal by the way that cap body to be arranged in the centre of the body of rod
, by the design of annular groove in cap body, glue can be placed in annular groove for threaded rod so as to realize bidirectional fastening
Liquid can guarantee that glue will not cover the screw thread on the first bar by the setting of polished rod for sealing and anti-leakage, to guarantee tight
Gu effect.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
