Description
Technical field
The utility model belongs to bolt field, more particularly, to a kind of bolt.
Background technique
Common bolt connection failure and the biggish occasion of stress pre-tighten with it is locking, in working environment
It is easy to happen corrosion phenomenon in the case where poor, leads to Joint failure.Meanwhile common bolt influences aesthetics, it is not easy to tight
Gu substantially not applicable in life.
There are various bolts in existing technology, but they all have some unified drawbacks, are easy split
It unloads, is stolen, screw is easy Automatic-falling in vibration environment, needs running check or installs anti-drop device, most of spiral shell additional
Nut and screw can occur while rotating when nail installation, installation is inconvenient.
Utility model content
The purpose of the utility model is to provide a kind of structure is simple, convenient and practical Mobyneb bolt is especially suitable for house
It is used under the conditions of front yard and high intensity.
The technical solution of the utility model is: the utility model discloses a kind of bolts, including bolt head, bolt buckle and spiral shell
Column, the stud include upper screw thread and lower screw thread, it is characterised in that: the bolt head upper surface is the spherical surface of protrusion, bolt head
A raised tenon is arranged in lower surface, and the bolt buckle is cylindricality, and four angles of the bolt buckle lower surface are set as cambered surface, spiral shell
The groove of the notch of one with the cooperation of bolt head lower surface tenon, the tenon that the bolt head passes through bolt head is arranged in the upper plane of bolt button
With the groove of the notch mortise-tenon joint of bolt buckle, the bolt buckle and Stud connection part are set as fillet, the upper screw thread and lower spiral shell
Have among line one section it is non-threaded, the stud is set as chamfering far from bolt head side.
Further, the length of tenon of the smooth no grooving of the spherical surface of the bolt head upper surface, lower surface is less than the groove of the notch
Effect is optimal.
Further, the groove of the notch is a blind hole.
Further, the upper screw thread is located at close to bolt buckle side.
Further, the upper screw thread is located at close to bolt buckle side.
Further, the lower screw thread is located remotely from bolt buckle side.
Further, the major diameter of the upper screw thread and lower screw thread is greater than stud diameter.
The utility model has the advantages and positive effects of:
1, the bolt head of bolt and bolt buckle are by mortise-tenon joint, and bolt buckle is completely covered in bolt head after installation is complete,
And it combines closely with workpiece, bolt, not easy to disassemble can be hidden, prevent from stealing, and bolt head is smooth, there is ornamental value.
2, the bolt buckle of bolt is quadrangular, when installation in stud bolt slot, if cooperated with nut, is kept away in installation process
Exempt from nuts and bolt common rotation, if the upper screw thread of itself and lower screw thread provide the effect of fastening and positioning without nut,
And stud can be used in high-intensitive large scale equipment, and intermediate non-threaded area can install workpiece.
3, the fillet of bolt can provide buffering in fastening bolt, prevent the damage to screw thread, and after tightening can
Certain pretightning force is enough provided.
4, the cambered surface at four angles of bolt buckle lower plane makes it facilitate installation, reduces abrasion.

Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
It as shown in Figs. 1-2, is the utility model structure diagram
A kind of bolt, including bolt head, bolt buckle and stud, the stud include upper screw thread and lower screw thread, and feature exists
In: the bolt head upper surface is the spherical surface of protrusion, and a raised tenon is arranged in bolt head lower surface, and the bolt buckle is column
Shape, four angles of the bolt buckle lower surface are set as cambered surface, and one and bolt head lower surface tenon is arranged in the upper plane of bolt buckle
The groove of the notch of head cooperation, the bolt head pass through the tenon of bolt head and the groove of the notch mortise-tenon joint of bolt buckle, the bolt buckle
Be set as fillet with Stud connection part, have among the upper screw thread and lower screw thread one section it is non-threaded.
The smooth no grooving of the spherical surface of the bolt head upper surface, it is optimal that the length of tenon of lower surface is less than groove of the notch effect.
The groove of the notch is a blind hole.
The upper screw thread is located at close to bolt buckle side.
The upper screw thread is located at close to bolt buckle side.
The lower screw thread is located remotely from bolt buckle side.
The major diameter of the upper screw thread and lower screw thread is greater than stud diameter.
After bolt is installed, bolt head 1 is installed additional at bolt buckle 2, both made more beautiful outside bolt, while bolt head
1 is close to workpiece, prevents from being stolen, is also prevented from the corrosion of external sewage.
The structure of bolt buckle 2 makes that whether there is or not nuts to be applicable in, and when having nut, bolt buckle 2 sticks into bolt mounting groove can
To prevent screw bolt and nut in installation process from rotating together, when no nut, there is the groove of the notch 7 of allen wrench in bolt buckle 2.
Bolt buckle 2 and 5 junction of stud are provided with fillet 3, provide buffering during the installation process, avoid damaged screw,
Certain pretightning force is provided simultaneously.
It is provided with screw thread 4 and lower screw thread 6 on stud 5, tightening and positioning can be played the role of, while can be applicable in more
Kind situation, non-threaded region can install workpiece, for the fitting depth of different length, the position of adjustable nut.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
