Abstract

A kind of brass stud, belongs to mechanical fastener technical field.It comprises copper stud body and the first stud of being equipped with at copper stud body two ends and the second stud, first stud and at least one stud termination of the second stud arrange stop bit post, copper stud body is Special-Shaped Column body structure, and damaged surface is made up of with two the circular arc faces being connected two planar surface portion both sides respectively two planar surface portion be parallel to each other.The utility model is by being set to the special-shaped column structure be made up of with two the circular arc faces being connected two planar surface portion both sides respectively parallel two planar surface portion by copper stud body, in rundown process, two planar surface portion can be clamped with pliers to screw in, effectively can prevent from skidding and twist tighter simultaneously, and stop bit post is set at the first stud and at least one stud termination of the second stud, avoid stud thread root and be all screwed into body element tapped hole, reduce the stressed powerful of this thread root, thus improve its working strength, extend working life.

Description

A kind of brass stud
Technical field
The utility model belongs to mechanical fastener technical field, is specifically related to the brass stud that a kind of structure is simple, easy to connect, mechanical strength is good.
Background technique
Stud is all threaded cylindrical fastening pieces in a kind of two ends, is widely used in the connection of valve, mechanical structure etc.Connecting rod in the middle of existing pair of ice stud, connecting rod two ends are provided with threaded screw rod, two ends rely on screw thread to be connected with other component, and general stud is all be screwed into completely in the tapped hole of body element, by the squeezing action of thread root and main body screw, stud is used to be fixed in body element, thread root is stressed maximum, and in the course of the work because vibration etc. makes it rupture, and middle part is cylindrical structure, bad operation when making to tighten, program is tightened in impact.
Model utility content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide the brass stud that a kind of structure is simple, easy to connect, mechanical strength is good.
Described a kind of brass stud, the first stud comprising copper stud body and be equipped with at copper stud body two ends and the second stud, it is characterized in that the first described stud and at least one stud termination of the second stud arrange stop bit post, described copper stud body is Special-Shaped Column body structure, and damaged surface is made up of with two the circular arc faces being connected two planar surface portion both sides respectively two planar surface portion be parallel to each other.
Described a kind of brass stud, is characterized in that on described circular arc face, interval arranges one group of stiffening rib.
Described a kind of brass stud, it is characterized in that described stop bit post is for circular or square structure, its external diameter is less than the external diameter of equal first stud and the second stud.
Described a kind of brass stud, it is characterized in that the first described stud and the second stud termination all arrange stop bit post, the first stud and stop bit column length summation, the second stud and stop bit column length summation are all greater than the length in the main body screw hole be threaded with the first stud and the second stud.
Above-mentioned a kind of brass stud, the first stud comprising copper stud body and be equipped with at copper stud body two ends and the second stud, the first described stud and at least one stud termination of the second stud arrange stop bit post, described copper stud body is Special-Shaped Column body structure, and damaged surface is made up of with two the circular arc faces being connected two planar surface portion both sides respectively two planar surface portion be parallel to each other.The brass stud that the utility model obtains by adopting above-mentioned technology, by copper stud body being set to the special-shaped column structure be made up of with two the circular arc faces being connected two planar surface portion both sides respectively parallel two planar surface portion, in rundown process, two planar surface portion can be clamped with pliers to screw in, not only effectively prevent from skidding, and it is laborsaving, tighten more convenient, and the utility model arranges stop bit post at the first stud and at least one stud termination of the second stud, in connection procedure, avoid stud thread root and be all screwed into body element tapped hole, thus reduce the stressed powerful of this thread root, reduce suffered stress, thus improve its working strength, extend working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional profile structural representation of the utility model copper stud body.
In figure: 1-stop bit post, 2-first stud, 3-copper stud body, 301-planar surface portion, 302-stiffening rib, 303-circular arc face, 4-second stud.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described:
As depicted in figs. 1 and 2, a kind of brass stud, comprise copper stud body 3 and be equipped with the first stud 2 and the second stud 4 at copper stud body 3 two ends, in the first described stud 2 and the second stud 4, one of them stud termination arranges stop bit post 1, also can be that two stud terminations arrange stop bit post 1 respectively, this stop bit post 1 is circular or square structure, its external diameter is less than the external diameter of equal first stud 2 and the second stud 4, first stud 2 and stop bit post 1 length summation, second stud 4 and stop bit post 1 length summation are all greater than the length in the main body screw hole be threaded with the first stud 2 and the second stud 4, such thread root of the first stud 2 and/or the second stud 4 of avoiding screws in body element tapped hole, thus reduce the stressed of thread root, avoid in working procedure because vibration etc. makes this brass stud rupture, improve its working life.
As shown in Figure 2, copper stud body 3 is set to Special-Shaped Column body structure and replaces existing cylindrical structural by the utility model, the damaged surface of this copper stud body 3 is made up of with two the circular arc faces 303 being connected two planar surface portion 301 both sides respectively two planar surface portion 301 be parallel to each other, during use, two planar surface portion 301 can be clamped with pliers to carry out tightening operation, avoid the skidding of cylndrical surface, increase stressed, make to tighten more laborsaving, in order to improve the intensity of brass stud, the utility model interval on circular arc face 303 arranges one group of stiffening rib 302, in the utility model embodiment, each circular arc face 303 is provided with 3 groups of stiffening ribs 302, improve it by force intensity.
