Description
Technical field
The utility model is related to a kind of attachment means, it particularly relates to a kind of anti-loosening connector.
Background technology
In the prior art, attachment means have a variety of.Wherein, a kind of the more commonly used device is to use nut and screw rod knot
Structure.Through hole is provided with nut, the through-hole wall is provided with internal thread.Screw rod outer surface is provided with external screw thread.Screw rod is screwed in into spiral shell
In female through hole, external screw thread and internal thread are adapted.So play connection function.But the attachment means of the structure are for a long time
After use, screw rod and nut can produce loosening, be unfavorable for the fixing of connection.This is the technology that those skilled in the art face
Problem.
The content of the invention
Technical problem：Technical problem to be solved in the utility model is：A kind of anti-loosening connector is provided, it connects tool
There is stability, be not likely to produce loosening phenomenon.
Technical scheme：In order to solve the above technical problems, the utility model embodiment is adopted the following technical scheme that：
A kind of anti-loosening connector, the device includes outer nut, inner nut and screw rod, and outer nut includes top layer and is connected to
It is provided with bottom below top layer, top layer in first through hole, bottom and is provided with the second through hole, inner nut is located in the second through hole, institute
State and third through-hole be provided with inner nut, screw surface is provided with the first external screw thread, the hole wall of first through hole and third through-hole be provided with
The first internal thread that first external screw thread is adapted；The outer surface of inner nut is provided with the second external screw thread, and the hole wall of the second through hole is provided with
Second internal thread, the second external screw thread and the second internal thread are adapted；And second externally threaded rotation direction and the first externally threaded rotation direction
Conversely.
As preference, the height of the inner nut is more than the height of bottom.
As preference, described anti-loosening connector, in addition to packing ring, provided with projection in the endoporus of the packing ring；Institute
Screw surface is stated provided with the notch along screw axis direction, projection is located in notch.
Beneficial effect：Compared with prior art, the anti-loosening connector of the utility model embodiment, including it is outer nut, interior
Nut and screw rod, inner nut are located in the second through hole of outer nut, the thread rotary orientation coordinated between inner nut and screw rod and outer spiral shell
The thread rotary orientation coordinated between female and screw rod is identical, the thread rotary orientation coordinated between outer nut and screw rod and outer nut and inner nut
Between the thread rotary orientation that coordinates it is opposite.So, operationally, in the event of the situation of loosening, it is assumed that be adapted on outer nut with screw rod
The first internal thread have the trend turned clockwise, then the second internal thread being adapted on outer nut with internal thread has rotation counterclockwise
The trend turned.Because the first internal thread and the second internal thread are arranged on outer nut simultaneously, and inner nut and outer nut are adapted,
So outer nut can not rotate, inner nut can not also rotate.It is thus to realize anti-loosening effect of connection member.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model embodiment；
Fig. 2 is the top view of the utility model embodiment middle washer.
Have in figure：Outer nut 1, top layer 101, bottom 102, inner nut 2, screw rod 3, packing ring 4, projection 401.
Embodiment
Below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
As shown in figure 1, the utility model embodiment provides a kind of anti-loosening connector, including outer nut 1, the and of inner nut 2
Screw rod 3.Outer nut 1 includes top layer 101 and is connected to the bottom 102 of the lower section of top layer 101.First through hole, bottom are provided with top layer 101
The second through hole is provided with layer 102.Inner nut 2 is located in the second through hole.Third through-hole is provided with the inner nut 2.The surface of screw rod 3
Provided with the first external screw thread, the hole wall of first through hole and the hole wall of third through-hole are respectively equipped with first be adapted with the first external screw thread
Internal thread；The outer surface of inner nut 2 is provided with the second external screw thread, and the hole wall of the second through hole is provided with the second internal thread, the second external screw thread
It is adapted with the second internal thread；And the second externally threaded rotation direction and first externally threaded oppositely oriented.
Using said structure anti-loosening connector when, first by inner nut 2 be arranged on outer nut 1 on, inner nut 2 is revolved
In the second through hole for entering bottom 102.Second external screw thread of inner nut 2 and the second internal thread of the second through hole are adapted.After installation,
Again by inner nut 2 and the integral installation of outer nut 1 to screw rod 3.The first internal thread in the first through hole of the top layer 101 of outer nut 1
It is adapted with the first internal thread in the third through-hole of inner nut 2 with the first external screw thread of screw rod 3.Thus complete the peace of part
Dress.Due to the second externally threaded rotation direction and first externally threaded oppositely oriented, so operationally, in the event of the situation of loosening,
Assuming that the first internal thread has the trend turned clockwise, then the second internal thread has the trend of rotate counterclockwise.Due to outer nut 1
The first internal thread and the second internal thread are above provided with simultaneously, and inner nut 2 and outer nut 1 are adapted, so outer nut 1 can not revolve
Turn, inner nut 2 can not also rotate.It is thus to realize anti-loosening effect of connection member.Whole part is simple in construction.
As preference, the height of the inner nut 2 is more than the height of bottom 102.If the height of inner nut 2 is less than bottom
The height of layer 102, then inner nut 2 can not be completely screwed into the second through hole of bottom 102.Therefore, the height of inner nut 2 is set
It is set to the height more than bottom 102.So may insure that inner nut 2 is completely screwed into bottom 102, i.e., the top surface of inner nut 2 and
The bottom surface contact of top layer 101.Meanwhile, in this way, also helping dismounting.Because the bottom of inner nut 2 is located at the outer of bottom 102
Side, it is possible to screw out inner nut 2 from the through hole of bottom 102 second.
As preference, as depicted in figs. 1 and 2, described anti-loosening connector, in addition to packing ring 4, the packing ring 4
Provided with projection 401 in endoporus；The surface of screw rod 3 is provided with the notch along the axis direction of screw rod 3, and projection 401 is located in notch.Peace
During dress, packing ring 4 is located at the top of outer nut 1.When the projection 401 on packing ring 4 is located in notch, packing ring 4 can not rotate.This is conducive to
Reduce the loosening trend of inner nut 2 and outer nut 1.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
